A HIGH-RELIABILITY DISTRIBUTED ETHERNET MEASUREMENT AND CONTROL SYSTEM

摘要

A high-reliability distributed Ethernet measurement and control system includes a main central control computer (1) with the function of communication. The main central control computer (1) is connected with a network exchanger (4) via communication lines. The network exchanger (4) is connected with the node devices (9, 10, 11, 12, 13) via communication lines. The node devices (9, 10, 11, 12, 13) are connected with multiple sensors and operating devices (14, 15, 16, 17, 18) respectively via AD/DA board. Output of each sensor and control instructions transmitted to the operating devices are converted and then transmitted via a common data bus.
