The second is that we can observe in not 8 high-order microcontroller fields of microcontroller employ, the trend that the microcontroller of the 32-bit microcomputer replaces 16 bit microcontrollers continuously is quite obvious, the microcontroller of the 32-bit microcomputer surmounted 16 microcontrollers for the first time in 2006, the accounting for rate has occupied the second, its number of outloading will rise continuously at the same time, by 2010, the 32-bit microcomputer microcontroller will have an opportunity to be up to 32.62% of the taking rate of market, become another important microcontroller application.

Summary: This text propose one Fu set up leaf USB simple and easy to realize in data collecting system in the spectrometer. Keyword: USB; Microcontroller; Multiple channel; Data acquisition

The foreword will often meet the situation needing to input various analog signals in the computer observes and controls the system, must need to change A/D at this moment. In some actual projects sometimes, choose some dedicated data collecting cards in order to gather some analog quantity, not only make the system more complicated,but also not apt to realize the function is expanded, increases the systematic design cost yet. On the other hand, the USB interface is easy to operate more and more widely used, so the USB interface of the Apparatus is a development trend. XFT-1 type open Fu set up leaf, vary spectrometer, adopt classical the intersection of Michael and modest interferometer, the light intensity after interfering changes with movement of the index glass, the electro-optic recipient target transforms the mere strong signal of secular change that is received for the corresponding voltage signal. In order to remove because not even errors caused of the migration velocity of the index glass, adopt the double channel in the module, measure the reference light (He-Ne laser) at the same time And after examining the light source, utilize and consult photic information to correct the position error of optical measurement examined. In XFT-1 type open Fu sets up the leaf and varies the spectrometer, have adopted such simple and easy USB data collecting system that this text put forward. In view of the economic, practical factor, have adopted one-chip computer and common USB interface chip in the system, will both combine the data acquisition system design which will realize the USB interface. The epistasis PC has adopted C # language programming, the data real-time display that gets gathering, handling the analysis, data to keep and print.

The hardware, circuit design this, system regards ADuC841 of ADI Company as the core to realize data acquisition and control. This one-chip computer lasts single instruction cycle 20MIPS 8052 kernels and 8 passways of 420Ksps at a high speed, 12bit A/D converter, support online download. Control device and ADC have integrated and shortened development time, has improved the stability of the system. This text regards oozing the permanent USB interface chip CH375 in Nanjing as the core and realizes USB data transmission. The following characteristic: Compatible USB2.0; Shield the associated USB agreement under the built-in firmware mode, finish canonial USB and enumerate the configuration procedure automatically, do not need local end control device to do any treatment at all, has simplified the firmware programming of the one-chip computer; One grade of interface of provision of equipment of common Windows driver program, offer API to employ the layer interface through DLL. The interface circuit diagram of ADuC841 and CH375 is shown as in Fig. 1. Two kinds of data link connecting means that and run side by side that ADuC841 and CH375 are serial. Adopt the way of running side by side in the module in order to improve the speed, link P0 mouth of ADuC841 with parallel bus of CH375. Besides reading and writing signal connection, adopt A14 as the address bit. A14 =0,Show it is the data on the data bus; A14 =1,Order on representing the data bus. In USB transmission course, ADuC841 and CH375 touch off through external interruption, adopts INT0 external interruption pin of ADuC841 to connect with INT # pin of CH372 directly. CH375 exports as the low level in normal working hour ACT # pin, so add a luminescent diode and point out whether the USB interface chip is the normal operation between power and this pin. The luminescent diode one has killed and offered important information for debugging of the lower-position unit procedure bright.

The system software of systematic software design is by the lower-position unit procedure (firmware procedure) , USB systematic driver program and three parts of utility program form. Utilize USB agreement to transmit the machine format model and is shown as in Fig. 2. Data acquisition and data transmission subroutine that the software program of this system mainly includes language C wrote the one-chip computer, and the data real-time display which the epistasis PC written with C # gathers, handling analysis, data keeping and procedure of sealing. The firmware procedure of the program device of the lower-position unit is a core of the data collecting system, the lower-position unit procedure mainly utilizes KeilC51 to be written. In order to reduce the complexity and increase the maintainability of the procedure, the lower-position unit programming adopts and inquires about the way carried out again in order that the PC spreads over through the USB interface first. Presume the agreement in upper computer and lower-position unit communication, presume corresponding command word and check field in the agreement. The master command word has systems that finds whether it is normal and presuming sampling frequency, presuming that samples the point size, samples the enabling signal etc. or not. The intersection of lower-position unit and for scan the intersection of command word and variable constantly, see it effective main program. It is original to be monitored the command word and set invalid, after the upper computer sends out the new command word, the lower-position unit enters the interrupt subroutine to receive the command word, the command word sets effective. After the content that the lower-position unit scans the new command word, carry out corresponding operation, then will wait to monitor the command word to set invalid and continue waiting for the new command word. The function of the task of refinement of this kind of design, help to develop, debug and safeguard. The data acquisition subroutine runs after the main program receive and start the course command word of data acquisition. After the one-chip computer receives the command word that the upper computer sends through USB over, start the course of data acquisition. It utilize slices of inner timer set for, gather time interval, pay data acquisition with slices of inner ADC. In the interrupt subroutine while booking, the one-chip computer will gather the data of two passways, deposite them in the buffer in certain order, then check whether the buffer is full, if the buffer is discontented, the sub end of program of timer interrupt, otherwise send the data in the buffer to the upper computer through CH375, clear out the buffer, the sub end of program of timer interrupt. It is easy to develop a great advantage of USB driver program, this system. Nanjing oozed the permanent company to already offer the general USB driver program to user. Only need installation Off-The-Shelf USB to drive the erection procedure, it has offered a lot of interface functions for development of the utility program. Because mainly adopt and upload in batches and download the way in batches, mainly use CH375ReadData, functions such as CH375WriteData,etc.. This part does not need writer. The procedure upper computer procedure of the upper computer can adopt many kinds of software development tools, this system has written the utility program with C # language under Visual Studio2005 development environment. Mainly finish reading, revealing, keeping, opening and printing the work of data,etc.. It is the key part of the upper computer procedure that the data read the course. For in from under location machine-readable data fetch at influence by interface smoothness that be responded to, make use of multithread to realize the data to read in the programming. Data acquisition work finish in single sub thread, but main the intersection of thread and piece responsible for, finish mouse, keyboard response in user. In the sub thread of data acquisition, offer API to employ the layer interface to visit the buffer in USB driver program directly through DLL. After succeeding in turning on the apparatus, utilize CH375WriteData interface function to write the command word in the buffer, send the order to the one-chip computer; Utilize CH375ReadData interface function to read the data in the buffer, the data gathered. Under Visual Studio2005 development environment, it is relatively lower to write the difficulty of program development of the upper computer. It is ocular that the real-time display of data has increased course of data acquisition. The data gathered set up a software timer through GDI + drawing on PictureBox controlling part, paint the figure once through regular hour again while being every, because the time interval is less than 0.1s, it is a curve of continuous change visually. Machine format save and it opens functions to be to utilize StreamWriters and StreamReader completion of C in the # mainly. Print data and figure and mainly use PrintDocuments, after transferring Print method, characters and graphic output that will need printing in PrintDocument_PrintPage incident or painting again and can be printed.

The simple connection which utilizes one-chip computer and USB interface chip is the getting extendible data acquisition module of a USB interface to conclude the speech, need, expand data storage outside, meanwhile, still very abundant acquisition system this peripheral hardware and the intersection of I/O and resource carry on expansion functionally on the abundant slice with ADuC841. In XFT-1 type open Fu sets up the leaf and varies the spectrometer system, have utilized ADuC841 to pass the synchronous electric machine control Michael modest interferometer index glass seat. Through testing, the precision great of sampled data of this system, the transmission rate is very fast, the characteristic is steady, after through linking with PC, not merely make the memory capacity of the data great, and apt to carry on data processing, economy simple, set up leaf vary spectrometer characteristic steady in the system in XFT-1 open Fu.

"Enterprise's whole competitiveness of spare part of the Chinese car shows a tendency to glide, because value host computer more than the spare part the thought is serious, the lagging behind has become the maximum obstacle of industry's development of spare part of the Chinese car. "

" lagging behind " It is a great obstacle of industry's development of spare part of the Chinese car. China's auto industry committee member of consultative committee Chen GuangZu thinks, the reason why will present " lagging behind " ,Because of " Value host computer more than the spare part " The thought has been existing in Chinese car trade all the time, has influenced the development of the spare part trade. In addition, the scientific and technological progress of international automobile industry changes with each passing day, make China actually strengthened on the backward spare part industry and disparity of world level. This kind of " lagging behind " Behave on the advanced product market particularly obviously.

Chen GuangZu thinks, according to development of the global automobile industry, the informationization has already widely permeated in, the integration of automobile industry and information industry brings about the deep change in automobile industry chain, Chinese cars industry are backward a lot in this respect. He points out, the country supports very much in this respect, have organized the relevant department many times, invite the numerous experts including academician of the Chinese Academy of Sciences and Chinese Academy of Engineering, carry on the discussion on automobile industry and integration question of the information industry, but still there is not a result of essentiality so far.

At the the intersection of South Korean and car MCU that assemble ' Microcontroller) Supplied mostly by South Korean Samsung electronics corporation, the level that the South Korean automobile industry grows with each passing hour is thus clear. And MCU assembled on the Chinese car all adopt the imported products, and because MCU characteristic is higher and higher, must truss up and design, need to tell the other side the data to go on in coordination with the design. If there is less output, some transnational MCU Companies will improve price, this innovates for spare part enterprises to causes and does not threaten small. Moreover, triodes in the Chinese car electricity generator factories are nearly all adopted and imported, the reason is afraid it influences quality that the products which Chinese enterprises produce are unreliable. The diodes, such fundamental original paper of triode all depend on import, it is obvious the Chinese car electronic product demands urgently to further innovate.

In fact, China has some good car electronic product manufacturing enterprises too, but overwhelming majority of these enterprises produces the vehicle carried electronic product, the enterprises producing vehicle-controlled electronic product are few. Chen GuangZu shows, the vehicle carried automatically controlled products are the leading part which promote the car characteristic, but because the difficulty is large, it is very slow to develop in China. China can already produce ABS now ' Anti-lock brake system) Wait for the car electronic product, they can use on independent brand car. Develop ESP in a more cost-effective manner in the world at present ' Electronic stabilization system) ,China is studying too, but will really apply to the car, will need quite long period. Its major cause is, ESP and car some procedure degrees of correlation in design are greater, should organize in coordination with the design, but there are doubts in the completed car factory, have increased the difficulty of development of ESP.

At information age, the products are upgraded very fast. Chinese car spare part enterprises should improve the competitiveness, must innovate constantly. Chen GuangZu points out, Chinese car spare part enterprises have not accomplished this. For example small-scale the intersection of diesel engine and the intersection of rail and technology altogether, need, run, go on, control rationally to the high speed of car. Use spring in the past, use electromagnetic valve after altogether rail technology appears, and third generation rail technology adopt piezoelectric ceramics together, China some factory trial-produce too, but because characteristic reach require, have to import. Developing the nanometer piezoelectric ceramics in the world at present, may compress volume and pump one greatly. It is a very big problem whether Chinese enterprises could keep up with.

On the existing advanced products, already there is very great disparity with the world level in China, the development to the new spare part of future is a blank even more or stays in academic discussion. At present, Delphi, Siemens, Company, SKF of Sweden, develop and coil out to pass the movable property product, use the products in substituting direction machine,etc.. This kind of product should actually use the technological principle of a kind of electromagnetic rheology, substitute mechanical drive through the way that the particle in the liquid is condensed and frozen degree, totally change the car and control the way. Chen GuangZu points out, have seen the research that some theses introduced in this respect 3 years before, but can't predict the progress altogether in many aspects such as research, application, fund, technical support of combination involving production,teaching,research, country or locality, enterprise,etc..

New series S12XS are the supplement to high-performance series S12XE, The goal is orientated as body of a motor car and passenger's comfortableness application

The report of 16 days of Japan's economic news, NEC electronics corporation and auspicious the Sa 's (Renesas) Negotiating and amalgamating, if reach an agreement, can be expected to leap to Japan's chip fabrication tap, the annual camp charges and approaches 13 billion dollars.

The report points out, negotiation between both parties has already entered the final stage, has hoped to reach an agreement before the end of April. It is reported, the new company may continue to use NEC electronic name, and continue being listed in Tokyo stock exchange.

Spokesman, Company of NEC, show to this chip department is assess ways of different promotion competitiveness under command, and auspicious Sa forms an alliance to select, but not made any decision yet. Auspicious spokesman Sa refuses to comment. Amalgamate into news, encourage, NEC stock exchange rise park, lock in Tokyo 16 such as stock price, act as, charge so as to 930 Japanese yen.

Auspicious Sa is the second largest chip manufacturer in Japan, established jointly by Hitachi and Mitsubishi Electric; NEC electron ranks the third, 65% of the stock rights are held by NEC Company.

The last fiscal year stopping at the end of March, it was each about 680 billion Japanese yen and 555 billion Japanese yen that the camp of two companies charged.

If NEC electron and auspicious Sa amalgamates, replaceable rival's Toshiba, become the first largest chip manufacturer in Japan, and it is second only to Intel and the third major chip factory in electronic world of Samsung for the rank to leap to.

On the other hand, auspicious Sa is a very pointed microcontroller manufacturer of the world too, have 20% taking rate of market in the whole world; NEC electron rank the intersection of residence and time, global city accounting for rate 11%. The binding energy of both sides improves the accounting for rate in the global city to 30%, think of Karl semi-conductive company (FreescaleSemiconductor) from flying Vie for the leading throne that plays the market of microcontroller.

The analyst shows, after NEC electron and auspicious Sa are integrated, if can come to inspiration to make a profit through fully rectifying, can receive the positive benefit, the financial situation of the parent company can be expected to optimize too.

Mitsubishi unites securities analyst's field on the island and says on day in Tokyo: "Long-term the intersection of view and it, amalgamate, can let the two avoid in microcontroller and the intersection of mobile phone and the intersection of chip and the intersection of market and blind competition. "

Global economy slows down and ties down the chip price to drop sharply, chip manufacturers endure the bitterness that supply surplus and demand are weak and weary to the fullest extent too.

A lot of owners have already taken and dropped in production and reduced the staff etc. and rectified the measure in order to seek survival. However, because the economic recovery has not presented dawn yet, they will be whole to regard as and spend the route of prosperous severe winter of the semiconductor industry in comfort.

The chip manufacturers of Japan's memory must reach the company, reach an agreement with the government of Taiwan at the beginning of this month, plan to exchange important chip technology for the stock right of a new chip factory in Taiwan.
