全电子计算机联锁系统信息传输网络的设计

摘要

为满足全电子计算机联锁系统联锁机和执行机之间信息传输速率和可靠性的要求,设计了基于CAN总线和RS422总线智能通信单元的信息传输网络.该网络采用光纤通信技术、双网冗余技术和自愈网技术,保证传输速率和可靠性.现场运行情况表明,该网络能够满足全电子计算机联锁系统对信息传输的要求.%This article mainly introduced the design and implementation of information transmission network based on the CAN bus and RS422 bus intelligent communication unit. The network could meet the requirements of the information transfer rate and reliability of the All-electronic Computer Interlocking System. It was used fiber-optic communications technology, double network redundant technique and self-healing network technology to ensure the transmission rate and reliability. Results of field operations indicated that the network could meet the requirements of information transmission, for the All-electronic Computer Interlocking System.
