基于PhotoMos的前置数据采集器的开发

Data collection and drivers design based on the PhotoMos relays

利用AT90S8535单片机开发前置数据采集器,每路信号使用PhotoMos光继电器进行信号隔离,抗干扰能力强。介绍了AT90S8535单片机与计算机之间的串行通信,以及采集器的驱动程序的开发。

A data collection module is developed by using the AT90S8535 and each signal is isolated by PhotoMos relays,so that it has antijamming capability.The paper presents the method of the communication between the AT90S8535 and the computer along with the driver design of data collection.
