计算机联锁安全接口防护技术的运用和研究

接口功能是计算机联锁设备安全功能的重要组成部分,通过对计算机联锁安全相关接口在运用中存在的典型风险进行分析,采取继电器双接点采集、继电器双断驱动、安全通信协议传输等技术措施,对接口存在风险进行防护,使继电器驱采接口和安全通信接口发生故障时,计算机联锁的控制输出能够导向安全侧,保障计算机联锁在普速和高速铁路的安全可靠运用。

Research and Application of Computer Interlocking Safety Interface Protection Technology

Interface function is one key part of safety functions of computer interlocking equipment.Through analyzing the typical hazards in the application of safety-related interfaces of the computer interlocking system,technical measures opposed to protect against the hazards in its interfaces,such as relay double-contact acquisition,relay drive double-break,safety communication protocol.so,the control signal output of the computer interlocking system could be directed to the safety side when its relay drive interface or safety communication interface fails,thus ensuring the safe and reliable operation of the computer interlocking system in high-speed railways and ordinary railways.
