;散熱風(fēng)扇·通道連接適配器板等 1．1 計算機(jī)計算機(jī)的主要功能是通過usb接口控制測試診斷平臺，進(jìn)而完成測試平臺系統(tǒng)自檢、通道輸入/輸出的定義、發(fā)送測試激勵數(shù)據(jù)、接收響應(yīng)數(shù)據(jù)、數(shù)據(jù)計算與分析等工作。1．2 usb通信卡usb通道卡是連接計算機(jī)與測試平臺的橋梁。它的主要功能一方面是將計算機(jī)發(fā)送的控制命令、數(shù)據(jù)送到測試平臺的主mcu，使測試平臺完成各種測試任務(wù)；另一方面是將測試平臺中多mcu系統(tǒng)的自檢信息和測試結(jié)果送往計算機(jī)，以供計算機(jī)進(jìn)行判斷與分析。usb通信卡是基于ftdi公司的ft8u245bm芯片組成的，具有數(shù)據(jù)傳送數(shù)據(jù)高（達(dá)8mb/s）和即插即用等優(yōu)點。1．3 多mcu系統(tǒng)構(gòu)成的測試平臺多mcu系統(tǒng)由一個mcu和四個從mcu組成。所有的mcu均采用philips公司的p89c668單片機(jī)芯片，其內(nèi)部有可isp/iap編程的64kb flash程序存儲器和8kb ram，每個機(jī)器周期可采用六個時鐘周期，是傳統(tǒng)單片機(jī)（80c51）的兩倍。在其余雙工增強(qiáng)型uart中具有幀錯誤檢測和自動地址識別功能，另外還具有可編程的時鐘輸出功能及可編程的計數(shù)器陣列（pca）等，是philips公司mcu
