摘要
介绍了一种通用PC插卡式工业I/O开关量采集板。分别从工业开关量I/O卡的系统构成和结构特点、PC插卡的地址选择、输入输出接口电路硬件的研制与软件编程的实现等方面进行了详细论述。整个采集卡以可编程逻辑器件PLD为核心元件,具有工作可靠,控制简单,通用性强,性价比高等特点。
A general I/O switches acquisition adapter is introduced for PC plug - in card. Firstly the functional requisitions and fundamental structure of industrial I/O card is described briefly; then address choice of the digital card have been discussed in detail involving the input & output interface circuit principle, software programming and its implementation. Together with PLD the core component designed the whole acquisition card has the characteristics of working reliably, controlling simply, strong currency and high ratio of performance & price etc.
