Digital companion hard drive Cautions

Recently, I have a few friends in the digital companion warranty not too hard sometimes not recognized, there is also an important data need to Nikon D50 Battery Charger use. Fortunately, hard drive data can be export with professional software, but the drives have been overwhelmed, unable to continue services for the Photographer, it is recommended to replace the hard disk and then.

Powerful new digital camera

Pixels high, dual image stabilization, wide angle, 16:9, more light ... the basic elements of the home digital camera is gradually being drained, what expectations people will it? Gradually new boring yawn parameters rising again and again. Encourage them to purchase only

Is the "new", "parameters to improve" these people had gas something. Faced with this dilemma, manufacturers, how to increase the bright spot in the new models

Attract consumers to it?
Reference to examples of the IPOD, in fact, from a technical point of view, superior technology is not the IPOD with its successful main factors, of course, advertising. From the product itself, users continue to discover the fun in the process, thus more and more love for the IPOD is IPOD factor in winning. We are saying is that the main purpose of JVC AA-V16, AA-VG1 Charger the users to buy products, the most important issue is not a business need to be considered in making the product, the main function of the product is not a product to victory. IPOD aside its other aspects, just beautiful appearance, good sound quality, it is definitely enough to achieve such a success, because many people can do. Your IPOD to allow others to enjoy music, and other vendors' products can be. So to emphasize here is the distance of the peripheral differentiation, the main function with the same market competitors on the difference will be negligible. We are used to listening to music, then in addition to allowing users to meet the enjoyment of music, but also gives the user what this is the real distinction between opponents, beat his opponent. In short, the fun of the word, users achieve their goals is to achieve the purpose of the process is the main fun of.

Based on the the VB6.0 monolithic voltage inspection of the fuel cell system design

The fuel cell is a new driving force for the 21st century is expected to replace the internal combustion engine of the vehicle fuel system, it is a H2 and O2 of the chemical through the electrode reaction to be directly converted into electrical energy. A fuel cell stack, the multi-plate cells in series together to form the entire performance of the stack and single cell voltage has a great relationship. Therefore necessary to capture the voltage value of the single cell under different conditions, to find out the relationship between the H2 and O2 reaction environment and the single cell voltage by analyzing the development of fuel cell. This paper is to introduce fuel cell monolithic  Panasonic DMW-BCJ13PP Battery Charger voltage inspection test, analyze the system of units in progress 25kW fuel cell car project design. The system host computer software developed using VB6.0 programming language, the language is powerful, object-oriented and visual programming, friendly interface, particularly suitable for the graphical interface in the Windows environment and the user program preparation, data acquisition by more than 8-bit PIC microcontroller as the core data acquisition module to complete.

Composition and working principle of the 2 systems

The system consists of the host computer, the host microcontroller and a number of data acquisition module, shown in Figure 1. The host computer for an industrial control computer, its main function is to implement and host microcontroller through RS-232 serial communication receiver to collect data and send control commands; real-time display of the single cell voltage and draw the same time monolithic voltage changes trend curve; measurement data classification is saved to the database, and with a variety of mathematical analysis on the measurement results.

Master monolithic receiver control from the host computer command


Figure 1 System composition diagram

Control of each data module, and each module sent the data to be forwarded to the host computer via RS-232 serial port. The host microcontroller and data acquisition module with RS-485 bus to communicate, and set the main structure, the host microcontroller is set to host various data acquisition module from the machine. Host microcontroller in the detection of receipt of the host computer command, in accordance with the round robin way in turn to each data acquisition module hair collection command, issued an acquisition command after waiting to receive the collection module collecting data, if the waiting time received within the collection module sends back the collected data, the data package will be forwarded to the host computer; If you wait for the timeout still does not receive data directly down an acquisition module fat acquisition command, and so repeated the cycle continues.

Hardware and software constitute the data acquisition module is exactly the same, and communication through the RS-485 bus and the host microcontroller. Each data acquisition module in receipt of the test command from the host microcontroller 16 is responsible for testing the battery voltage value is sampled, and then sampling from the 16 battery voltage value package to send to the host microcontroller. Each data acquisition module can be taken in 16 single cell voltage, a corresponding increase or decrease the number of data acquisition module based on the total number of cells.

3 Data Acquisition Module

The acquisition of the single cell voltage in the inspection system is completed by each data module. The data acquisition module is based on PIC16F873 microcontroller as the core plus some external circuit shown in Figure 2. The PIC16F873 microcontroller is Microchip's production of a reduced instruction set (RISC), Harvard dual-bus and two-stage instruction pipeline structure cost-effective 8-bit embedded controllers, high integration, speed, low operating voltage, power consumption is low, the I / O directly drive the instruction simple and easy to use and features.

Host computer communication program design

Application VB6.0 embedded MSComm control will be able to send and receive serial data through a simple setup and programming. The MSComm control provides properties and methods of a series of packaged standard serial communication, and Nikon D5000 Battery Charger use it to build the application and the serial connection, complete the send and receive serial data. Its initialization properties set as follows:

The if MSComm1.PortOpen = True Then
MSComm1.PortOpen = False
End If
MSComm1.CommPort, = CommNum 'serial number
9600 baud, no parity, 8 data bits, one stop bit.
MSComm1.Settings = 9600, N, 8,1
MSComm1.InputLen = 0
MSComm1.RThreshold = 20 'to receive data threshold
MSComm1.SThreshold = 0 'Send able to fulfill the raw event
MSComm1.InputMode = comInputModeBinary

'Communications for the binary mode
MSComm1.PortOpen = True 'Open the serial port
MSComm1.InBufferCount = 0 'clear the receive buffer
MSComm1.OutBufferCount = 0 'clear the transmission buffer
Up bits of the next bit machine sends the data frame format shown in Figure 3:

Figure 3 receives the data frame type

Each frame of data consists of 20 bytes are: frame mark the beginning of a byte is FF; one byte of data group; 16 bytes of data; one byte checksum, the checksum and the group number and 16 bytes of data between the XOR result; last byte frame marks the end of the FD. 16 bytes of data, each byte represents a battery voltage value, an integer from 0 to 255 the number divided by 100 and get the actual voltage value, generally single cell voltage of 0.5V ~ 1.2V . By MSComm serial communication receive data can be used two ways to achieve a query, the other is the event trigger. In this system, select the event trigger mode, a receive events triggered whenever the number of data bytes in the receive buffer reaches 20. Receive communications procedures are as follows:

Private Sub MSComm1_OnComm ()
The dim InputData () As Byte
Dim strSum As Byte
Dim i As Integer
Dim Volvalue (0 To 18) As Single
With MSComm1
Select the Case. The CommEvent determine the communication event
comEvReceive: received 20 bytes of data
InputData = Input 'read the receive buffer
If InputData (0) = 253 And InputData (18) = 237 Then 'determine the received frame format correctly whether
For i = 1 To 17 Step 1
Volvalue (i) = InputData (i)
Next I
strSum = InputData (1)
For i = 2 To 17 'calculate the checksum
strSum = InputData (i) Xor strSum
Next I 'will accept the data validation and send checksum and XOR
If strSum = 0 Then 'If receive data is correct
Volvalue (N) = InputData (i) / 100
'Conversion to get the actual voltage value
............ Data Processing
Case Else
MSComm1.InBufferCount = 0 'clear the receive buffer
The MsgBox serial communication error
Exit Sub
End Sub

At this point is to pay attention to when reading data from the buffer the array InputData () must be defined as type Byte can not be Integer or JVC GZ-MG20U Battery Charger  Single, because the receive mode is set to binary. The host computer to send fewer instructions are very simple in this careful analysis.

5 Conclusion

A new, clean energy fuel cell more optimistic about the prospects for the 21st century, about the technology all help to promote further development to the practical stage. In this paper, made in the design of monolithic voltage detection and analysis system. For fuel cells, but can also learn from other similar multi-point detection and control system design.

Monitor use 9 Q: TV can use it for monitors

A monitor with TV and what is the difference? Why can not the TV as a monitor to use?

TV monitor in a simple but functional than in performance, but requires demanding than the TV, to reflect the following three points:

First, the image sharpness: As traditional TV stations to receive the RF signal emitted, the signal corresponding to the bandwidth of the video image is typically less than 6M, which is usually greater than 400 TV lines of resolution, requiring a monitor high image resolution, so the professional circuit in the channel on the monitor than traditional TV in terms of compensation and should have the bandwidth to enhance the circuit, so that a wider passband, higher image resolution.

Second, color reproduction, clarity if the main video channel from the amplitude-frequency characteristics of the decision, the reduction degree mainly by the monitor in red (R), green (G), blue (B) three primary colors of color phase signal and the luminance JVC GZ-MG21U Battery Charger signal is determined. As the monitor is usually observed as a static image, and thus the requirements of the monitor color fidelity higher than the TV, so the video amplifier channel professional monitors in brightness, color processing and R, G, B treatment should have accurate compensation circuit and a delay circuit to ensure that the light / color signal and R, G, B signals of phase synchronization.

Third, machine stability: monitor closed-circuit monitoring system in the form, usually 24 hours a day, 365 days a year using a continuous uninterrupted power (and the TV is usually only work a few hours a day), and some monitors application environment may be more difficult, requiring higher reliability and stability of the monitor. Compared with the TV, in the design, monitor current, power, temperature, and anti-radio interference, electrical shocks and failure-free margin and the average use of time are much larger than the TV, but must also monitor use of fully shielded metal enclosure to ensure electromagnetic compatibility and interference performance; in the selection of components, and monitor the use of components of the pressure, current, temperature, humidity and other characteristics of various components used to be higher than the TV; In the installation, commissioning and machine components, especially the aging process requirements, monitor requirements are higher, making the TV the whole time on the aging temperature is usually in the power line about 8 hours, and monitor machine you need to heat aging, humidity aging lines on the closed environment of the aging power more than 24 hours, to ensure overall stability.

Second, interlaced and progressive Monitor Monitor What is the difference?

Mainly refers to interlaced and progressive scan CRT monitor. Monitor image is two-dimensional image, and its reproduction process is two-dimensional input image into a string of pixels in the horizontal scan through the screen from left to right to achieve the uniform movement; vertical scan will be horizontal scan line at a constant rate by the vertical movement. Interlaced scanning refers to a scanned image Nikon EN-EL11 Battery Charger is divided into two, the first field (odd field) 1,3,5 and other odd-numbered scan lines, the second field (even field) even-numbered scan lines 2,4,6 and so on, two occasions together to form a complete image (ie one). So for the PAL system, the 50 scans per second, field, field frequency is 50HZ, the frame rate to 25HZ; for NTSC, the field frequency is 60HZ, the frame rate of 30HZ, although in the human visual screen to reproduce the is a continuous image, but the odd occasion even field switch will cause the screen flashes and significant effect of line spacing line. The progressive scanning refers to the scan line to scan line by line in sequence mode. Interlaced monitor with the image of poor quality, low-resolution, large and flicker noise and serious shortcomings. Progressive scan monitor is interlaced in order to eliminate the defects, the analog video signals into digital signals by digital color decoding, storage and control using digital signal technology to achieve a signal line or re-use (ie, slow read, high-speed readout) of 50HZ progressive scan mode, or further increase the frame rate to achieve 60HZ, 75HZ 85HZ so progressive scan mode. Progressive scan technology due to the input signal through the A / D converter into a digital signal by the digital video decoding and digital image processing circuit for horizontal and vertical scanning process, the channel bandwidth is greatly enhanced (up to 10MHZ-20MHZ), greatly improving clarity noise greatly reduced, while eliminating the progressive display line spacing between lines and line flicker, and frame rate of increase (such as 60HZ-85HZ) is to reduce or eliminate a large area flicker.

Therefore, progressive monitor, once available, will be welcomed by the users. Of course, as a progressive monitor the use of a line or re-use, frequency than interlaced line doubling, from 15625HZ into 31250HZ, 75Hz line frequency of progressive 46875Hz. Line frequency increased, the line output level of stability and reliability will be severely tested, the whole design and manufacturing costs greatly increased, so the machine's price is higher.

Third, the nominal 100Hz monitors currently on the market is interlaced or progressive?

If the problem 2 above, due to obvious defects 50HZ interlaced monitor, we can be achieved through the fold line 50Hz progressive scan, or times of market means to achieve 100Hz interlaced scan, the other can also fold lines + frequency (50Hz field * frequency * 1.2 or 1.5) form a 60Hz or 75Hz progressive scan line by line, but so far, we have yet to find domestic and foreign R & D and chip manufacturers are offering multiple lines + times the field that is 100Hz progressive technology and chips, in addition, To achieve 100Hz progressive displays, CRT deflection coil is exposed to 62500Hz line frequency to the driving frequency, the frequency of the tube Takayuki current technology is also difficult to manufacture them (except the monitor display tube used), it can be concluded that the is currently on the market can only monitor the nominal 100Hz 100Hz interlaced monitor.

100Hz interlaced scanning TV market in previous years has been all the rage, the representative chip solutions such as Philips MK-9 frequency processing module, Toshiba's Digital 100 module. But with the United States pixel technology and other times the Panasonic Lumix DMC-FS37 Battery Charger company's Trident (change) frequency of 60Hz (75Hz) the emergence of progressive processing module. 100Hz interlaced scanning technology has gradually been eliminated. 100Hz and 50Hz interlaced interlaced scanning technology also exists between the lines flashing, as in the crawling, creeping line, image and so rough and jagged edges. The 60Hz and 75Hz progressive scan monitor frame is due to the high technology and progressive ideal 100Hz scanning to eliminate the above defects, thus 100Hz 60Hz interlaced technology has largely been replaced by technology or 75Hz progressive.

Fourth, why the more vulnerable to monitor the magnetization? If the monitor is the magnetization should I do?

CRT monitor to the surrounding magnetic field and with magnetic material, such as metal cabinets MFL etc will generate an additional electron gun electron beam deflection, impact color purity and electron gun R, G, B tri-precision electron beam trajectory. In addition, the color picture tube inside the metal cover plate and the bracket to negative external explosion rings and other metal parts in the move will change the color monitor and the orientation of the magnetic field, magnetization of the magnetic field between these components, directly or indirectly affect the picture tube color purity and convergence, the screen will result in a partial cast. Therefore proposed as the monitor display is placed north and south (north-south perpendicular to the screen) and away from magnetic objects, as weakening the impact of the geomagnetic field. Monitor equipped with automatic degaussing circuit, the monitor can be used every time you boot normally CRT to eliminate the internal metal parts are the effects of external magnetic field. If the monitor is magnetized (expressed as poor color purity) relatively minor phenomenon, many times you can switch the magnetization of the metal parts to be demagnetized; serious even if the magnetic switch is still many times poor color purity, it had to use an external degaussing the method.

Network video server and its matrix of product you want to say four

Intelligent network video technology development and product homogenization of competition in the market share. As network video technology to further mature and stable, and increasingly large market applications, customer on network video technology awareness continues to improve, and begin to expect more features. And early of intelligent monitored, and behavior analysis, are concentrated in Hou end server Shang, cannot completed mass of parallel check, but as chip processing ability of improve, in network video server Shang integrated Intelligent analysis algorithm became may, this helps implementation large system Xia of security checks, conducive to will network video monitored products import to more high-end of monitored area, include airport monitored, and Metro monitored, and financial monitored industry and so on. At the same time intelligent technology will further enhance the technological content of network video, improve factory the barriers to JVC Everio GZ-MS120 Battery Charger  entry will help manufacturers out of disorder competition of the low price situation is conducive to large manufacturers to consolidate existing resources, networked video bigger and stronger. Emergence of a networked video itself has features to IT, is different from the traditional monitoring of important differences, with intelligent technology in network video play function on this most popular carriers, it will further enhance the dominance of Internet video, promote the upgrading of traditional monitoring industry.

Development of surveillance technology is to make it easier for customer application development, even in the matrix of this body is no exception. As a representative of traditional analog surveillance system, matrix is also begin to networked, intelligent direction. Albert world matrix has the support of network transmission, remote control, WEB access, as well as macro command operations, intelligent features such as cascading, which for the matrix of development open up a new road

Road.

Network video server market has formed a complete industry chain system, including upstream programme provides manufacturers, chip manufacturers, original manufacturers, dealers, manufacturers, and the broader public customers and industry groups. And have formed a powerful network video original manufacturers, these manufacturers will lead the development of Panasonic DMC-TZ15 Battery Charger network video product and market application occupies an absolute mainstay. In the network video market, foreign products occupy a small percentage are basically domestic manufacturers in the world. Now with the construction of national system for the safe cities, as well as the Beijing Olympics and other big events online, and China's security market is developing rapidly, network video applications is March. In this context, as Telecom, China Netcom and IT giants such as Samsung, Huawei, ZTE, intervention, but also in capital, technology and ideas had a significant impact on the network video market, in favour of bigger and stronger the network video market.

Major problems currently facing the online video market is the lack of uniform specifications, lack of industry standards. Algorithm does not have independent intellectual property rights, each taking its own algorithms to standard devices are not compatible with each other. Expect Chinese AVS standard can application soon entered a substantive stage.

Forecasts for the future from the survey of the history. Time in DVR also have raised questions about analog products. But till today, as represented by the matrices occupy enough analog monitoring equipment is still in the market share. Online video is still in development, rapid growth in this period of time is indeed very eye-catching, but it is not a replacement of DVR product positioning. Network video is suitable for networks, distributed monitoring, the centralized management of applications. DVR suitable for Nikon Coolpix S210 Battery Charger  areas of concentrated monitoring system. Both in its own environment that has a significant technical advantage and price advantage. In addition, in the application of industry, computer products represented by DVR with feature-rich, strong computing power, it can be change, the interface electronics products, so I think it is a network video product for quite a long time to come, DVR products, matrix products win the world situation.

Albert world of network video products include two kinds of DSP ASIC class product line. Currently algorithms to achieve a standard algorithm of MEPG4 and H.264. And according to different applications, you can provide a better algorithm to application environment standard. Also is developing intelligent algorithm technologies with independent intellectual property rights. In terms of product lines, heaven and Earth have been established include Albert network video server, network, network cameras, network video decoder changeup Dome, network high speed dome camera, network, network matrix multiple product lines. In the field of wireless, Albert world of network video products, including 3G, has a wide range of wireless applications to achieve a product integration. In the area of digital, Albert heaven already broke through the all-digital high definition network camera technology, mega pixels can be achieved levels of clarity.

World Albert of intelligent network matrix specifically for complex video monitored system provides powerful flexible of intelligent management, in processor engine, and communications bus schema, and high density video capacity, and Chinese macro directive programming operation, and MSIP intelligent integrated platform, and HD character overlay technology, and vector quantity speed control, and Panasonic Lumix DMC-FZ7 Battery Charger multilevel composite protection, aspects, implementation has innovation design, WEB set controlled management, and derivative intelligent module platform, and double line Chinese display, technology breakthrough, more close to market user of actual application demand, More in line with the trend of the future development of the matrix product

High-end micro hard disk activating multimedia mobile marketing

MP3 players, media players and Smartphones when you become a new growth point of consumption, suitable for portable devices that huge storage means becoming a bottleneck restricting the development of handheld devices. In fact, designers of portable products always have to think hard on more efficient use of storage space.When people try to place the video content in a portable device, massive storage is a necessary equipment. While Flash technology's price/capacity ratio has fallen, but still not as good as for the mechanical hard drive technology miniaturization even more quickly. In May 2004, the price of NAND Flash memory products to dive again, but 1GB Flash memory prices are still about $ 200 and Cornice company was launched in February 2004, using miniature hard drive technical production of the third generation of storage units (Storage Element,SE) capacity of 2GB and bulk prices are below $ 70. Although miniature hard drives on Panasonic Lumix DMC-LX3 Battery Charger  the volume and power consumption is higher than the Flash, but have little to an acceptable level. Cornice 2GB storage unit volume for 5x42.8x36.4mm, when the average current of 290 Ma, standby current of 100 micro-Ann. Currently available in popular HDD060 MP3 player Philip Muvo2 MP3 player and the innovation and technology on the use of such micro-hard disk enables massive storage.

Embedded reflect low cost strategy

"Our product called SE instead of a hard disk, because compared to standard hard drive, SE uses a voltage supply, electricity supply, on the main system drive and features such as caching, omits repeated signals to achieve lower cost and lower power consumption. "Cornice China Sales Manager Gao Ping in EDN CHINA magazine interview says.

There are a number of manufacturers involved in micro hard drive market, including traditional hard drive manufacturers Seagate, Hitachi, Toshiba and Huitong micro hard disk technology companies in southern China. But these vendors have to plug-in external products, mainly popular CF II on the PDA interface. Cornice products is embedded or built-in, although there was no  Nikon MH-65 Battery Charger removable flexibility, but you can reduce the total cost. "We use embedded policy, again in order to cut costs, embedded product than CF-II external hard drives in terms of cost savings 30-50%," Gao Ping said, "price of MP3 player is a very important consideration for consumers. ”

A few GB capacity 1-inch miniature hard in fact fill hundreds of MB of Flash memory and a gap between the dozens of GB. Compared with 1.8-inch hard drive, 1-inch miniature hard drive size has been reduced to a keychain size, power consumption also dropped to one-tenth, capacity is about 10 times the mainstream Flash products, micro hard drive is expected to be in a very excellent performance/price/volume ratio of activation portable class were originally part of high-end consumer market. A few GB capacity of the space can hold thousands of MP3 songs, two-hour VHS quality, MPEG compressed video, thousands of 1MB size, you can use to print photos of digital photos, or a complete GPS map of the continent, can also be used to copy or move a few large software. GAO Ping said that the current digital cameras sold in partner in both volume and price is not satisfactory, using miniature hard drives will significantly reduce the cost and volume.

Currently Cornice company provides embedded micro-hard disk 1.0GB, and 1.5GB three kinds of specifications.

Ideal medium for mobile video

Not hard to find, and for most audio applications such as MP3, miniature hard disk might just provide the convenience of having to frequently revise songs, on video applications, however, as the DV format tape the whole plate of video from a digital camera for an hour about space 0.5GB NM, so a few GB capacity happens to meet a couple of hours of video storage requirements. Miniature hard  JVC BN-VF823 Battery Charger drives will be replaced very soon new video of DV tapes to become a more ideal mobile storage media.Using miniature hard disk camcorder tape operations of not only omits the complex institutions considerably reduced volume, also does not have the precision machinery manufacturing Chinese manufacturers have the ability to enter the field of camera technology. Stored on the hard disk on the video tape editing and file management more convenient, do not need to DV conversion to other formats, enables playback of arbitrary starting point. If a 3.5-inch hard disk or recordable CD as the ultimate video storage media, than DV tape media costs reduced by more than half. Within a year or two, using miniature hard drive digital camera and camcorder combo products will be available at that time a dedicated camera products will end.Cornice Chairman Kevin Magenis said that 2GB micro hard drives as one of the important target market for video cameras.

Although mobile phone products and with mini-hard drive-free press, but with the multimedia mobile application download starts, miniature hard drive storage technology will be the only competent.

Embedded SE Cornice with proprietary 20-pin connector, but compatible with IDE interface specification. Since SE only retained the preamplifier and control circuits, such as your hard disk, hard disk drives, cache, clock and other functions must be performed by an external  Nikon EN-EL2 Battery Charger dedicated circuit or central processing unit that integrates these features to complete. Currently offers match with Cornice SE chip manufacturers including TI, Sigmatel, Philips, Freescale, Genesys Logic and Telechip company.
