摘要
介绍了一种典型的远程系统模型,探讨了其所涉及的关键技术,作为模型的实例,在计算机及其软件、数据库系统的支持下,利用开发工具自行开发了一套基于上位机/PLC及其网络的数据采集与检测系统.该系统具备经由PSTN或Internet/In-tranet的数据采集、控制远程PLC设备、传输现场动态数据采集与检测数据的功能.
Presented a typical model of remote serial communication system, and studied the key technology. With the support of computer and database, SCADA （supervisory control and data acquisition） system based on remote serial communication of PLC/host computer and their network are developed as an illustration by a developing tool. Data acquisition and its software are capable of inquiring and controlling PLC devices, transmitting check data of plant floor and doing trouble shooting via PSTN （public switched telephone network） or Internet/Intranet.
