This paper sums up some new points about the scanning circuit , like the compensating state and jumping in the cluster of non - linearity coefficient 摘要本文綜述了補(bǔ)償狀態(tài)和非線系數(shù)曲線中的跳變等有關(guān)掃描電路的新論要點(diǎn)。
There are a lot of methods available to create test vector . the thesis addresses their characteristics of the methods and special structure of boundary scan circuit respectively and come to a conclusion of pseudo - exchausive testing the most rational method applied to this situation 測試矢量的生成方法很多,本文在研究了各種方法的特性,以及邊界掃描電路的特殊結(jié)構(gòu)后,采用了偽窮舉法生成測試矢量。
This thesis discusses the realization of pcbs ict production through a concrete example in which boundary scan technology is applied , and presents a new method to improve the test speed , based on the analysis of boundary scan circuit and means for vector creation . he applys boundary scan ( bs ) to boundary - scan device on the board where bs features by easy vector creation , need less knowledge of the device 本文結(jié)合一個(gè)具體電路板在線測試實(shí)現(xiàn),首先討論了在ict中,采用邊界掃描元件測試技術(shù)實(shí)現(xiàn)在線測試生產(chǎn);并在分析歸納各種測試方法的基礎(chǔ)上探索一種新的改進(jìn)方法,即將deltascan技術(shù)與邊界掃描技術(shù)相結(jié)合以減少測試矢量,增加測試速度的一種實(shí)用方法。
By the advantage of high precision , strong anti - interference ability , long lifespan , etc , grating scale is the chief sensor in displacement measurement . however , as is restricted by the beam path structure , the scan frequency of the scaning circuit , etc , the maximum available measuring speed has a inverse proportion relationship to the measuring pace of a single grating scale 光柵尺具有精度高、抗干擾能力強(qiáng)、壽命長等優(yōu)點(diǎn),成為微納米位移測量的主要工具,但由于受光路結(jié)構(gòu)及信號(hào)檢測電路掃描頻率等因素的限制,單個(gè)光柵尺測量的最大允許移動(dòng)速度與其測量步距成反比。
On the one hand of hardwar : first of all , the thesis introduces the interiror structure of pic18f8260 and its distinguishing with other singlechip ; secondly , having narrated the structure and performance of gsm communicate module - tc35i module and the hardware performance process of communications interface of gsm ; thirdly , having studied the drived principle and dynamic scanned circuit of led ’ s panel ; lastly , having put forward serial interface circuit which the application of system . on the other hand of software which have accomplished the running of hardware : in design , utilizing mscomm control to realize the serial communication between computer and cell phone , utilizing at command to realize the cell phone control and sms receiving and sending operation , the pdu ( protcol data unit ) 設(shè)計(jì)上,利用mscomm控件實(shí)現(xiàn)計(jì)算機(jī)與gsm模塊間的串口通信,使用at指令實(shí)現(xiàn)對(duì)gsm模塊的各種控制和短信的收發(fā),分析發(fā)送和接收短消息的pdu ( protcoldataunit )格式、短信內(nèi)容、手機(jī)號(hào)碼、 smsc (短消息服務(wù)中心)號(hào)碼等;單片機(jī)與pc機(jī)之間的通信采用pic中c語言和c + +語言編程,以中斷方式實(shí)現(xiàn)pic18f8260與led的通信,同樣利用mscomm控件從漢字字庫的提取點(diǎn)陣碼,最后顯示在led上。
