摘要
基于GPRS/ADSL网络,开发高效、稳定、开放的SCADA系统。通过开发稳定可靠的通信服务器软件,实现上位机与下位机以OPC协议和Modbus协议进行通信,采集数据储存于数据库,实现冗余通信。
Based on the GPRS/ADSL network, an effective, stable and exoteric SCADA system is developed. Through the development of stable and reliable communication server software, the communication between upper-level machine and lower-level machine on OPC protocol and Modbus protocol is realized. The redundancy communication is realized by storing the acquired data in database.
