摘要
介绍一种远程数据采集系统，该系统采用ＳＴＤ总线工控机，使用由ＡＴ命令集控制的ＭＯＤＥＭ调制解调技术，通过公用电话网络进行远程数据通讯，可以实现多采集结点的实时远程数据采集、处理及管理功能。讨论该系统的设计特点，并对远程通讯中的求和校验、定时解锁、通讯失败补救等措施进行论述。
A remote data sampling system employing the industrial computer with the STD BUS is introduced in this paper. The hardware construction and the software design of the system, and the steps concerning with the remote data communication, are discussed. The system, with the techniques of Modem controlled by AT orders, can sample, process and manage data from remote multi sampling spots via public telephone network.
