摘要:

为预防铁路机务高压隔离开关操作过程中发生高压触电、高空坠落等重大人身伤害事故,利用网络通信、虹膜识别、连锁控制、计算机编程、大数据处理等信息化控制技术,研究不安全行为机控预防机制;采用定性分析法辨识隔离开关操作过程的不安全行为,针对辨识出的不安全行为研究监控系统;系统设计操作权限、分闸、验电、接地防护、合闸5个功能模块,模块设计内容涵盖隔离开关操作中可能发生不安全行为的所有项点,现场实践验证,消除隔离开关操作中存在的简化申请流程、分闸股道不匹配、验电无效、未撤线合闸等重大人身安全隐患。研究表明:该系统可使作业人员正确佩戴防护用品,规范操作隔离开关,实现作业过程由“人控”向“机控”的管控升级。

Abstract:

During the operation of high-voltage locomotive disconnectors of railways, serious personal injuries may happen, and they were caused by high-voltage electric shock and high-altitude falling. In order to prevent these accidents, information control technologies such as network communication, iris recognition, interlocking control, computer programming, and big data processing were used. The mechanism of machine control and prevention of unsafe behaviors was studied. The unsafe behavior during the operation of disconnectors was identified by qualitative analysis, and the monitoring system was studied accordingly. The system involved five functional modules, including operating authorization, opening, verification of live parts, grounding protection, and closing. The design content of the modules covered all the points where unsafe behaviors may occur during the operation of disconnectors. Field practice verified that the system could eliminate the major personal safety hazards during the operation of disconnectors. These hazards were caused by simplified application processes, mismatched opening tracks, invalid verification of live parts, and closing without line withdrawal. The results show that the system can make operators wear protective equipment correctly and standardize the operation of disconnectors. As a result, the operation process will shift from human control to machine control.
