The whole part of the data acquisition is build in a computer as two data acquisition cards. they are front card and rear card. the front card composed of four modules. they are : coin circuit module, data flow controller module, sdram array module and system bus interface module. the rear card composed of four odules. they are : asynchronous serial port interface module, adc control odule, ecg signal process module and gate control data produce module
數據採集模式實現部分的大部分工作是在前面板上完成的，後面板主要是一些外圍電路。前面板採集卡上從物理上來說主要有四塊電路:符合電路，數據流控制器電路， sdram陣列和系統總線介面電路組成。後面板採集卡從總體物理上主要有四塊電路組成: 485串列通信電路， adc控制電路，心電數據處理電路和門控信號產生電路。 -
Fieldbus builds up interconnections among field instruments and field control units by providing a wholly digital, bi - directional and multi - variant communication path, which has no i only greatly improved the reliability and ability of anti - disturbance, but also sharply reduces the costs of installation and routine maintenance. can ( controller area bus ) belongs to the asynchronous communication network
現場總線使得現場儀表之間、現場儀表與控制設備之間構成網路互連系統，實現全數字化、雙向、多變量的數字通訊，這大大地提高了系統的可靠性和抗干擾能力，同時節省了整個系統的投資、安裝及後期維護費用。
