铁路计算机联锁系统中通用输入输出接口研究

Study on common IN and OUT-interface in Computer Interlocking System

通过将计算机联锁系统中的输入输出接口从其它的执行模块中分离,可以使系统中各个模块的功能更加单一,更加专门化。提高整个系统的安全可靠性,也更有利于故障诊断及故障的排除。通过CAN总线组网,实现方便。输入模块采集设备状态上传给监测机,输出模块接收联锁机下发的执行命令,对现场设备进行控制。

By separating the IN and OUT-interface from the other blocks in Computer Interlocking System, could singularize and specialization the blocks in the System. Such could develop the reliability of the whole System, at the same time, it convenient for diagnosing failures and removing failures. To build a net by CAN bus was very convenient to come true. The IN-block sampled the states of equipments and sends them to the monitoring computer; The OUT-block received commands sent by the Interlocking computer to control the equipments.
