摘要
针对集宁至包头段增建第二双线工程,完成了在计算机联锁系统中对涉及安全输入信息的关键继电器增加后接点采集的接口电路设计,实现了闭环逻辑安全运算检查,进一步提高了计算机联锁系统的可靠性及安全性。
Based on the Jining-Baotou Second line project,the author completes the design of the interface circuit for the added back contacts collection of key relay related to safe input data in the interlocking system,which realizes the examination of close-loop logic safety calculation,and further improves the reliability and the safety of the interlocking system.
