【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.更多还原

【Abstract】 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.更多还原
