The invention provides a torque over-limit alarm system for a traction motor of an alternating-current drive internal combustion locomotive. The torque over-limit alarm system comprises a server, a WEB client and locomotive-mounted equipment, wherein the locomotive vehicle-mounted equipment comprises a vehicle-mounted antenna, a locomotive vehicle-mounted comprehensive information detection device, a locomotive microcomputer display screen and a locomotive microcomputer network control system, the locomotive microcomputer display screen is connected with the locomotive microcomputer network control system, receives and displays the actual torque of a locomotive traction motor and the running speed of a locomotive and transmits the actual torque and the running speed to the locomotive vehicle-mounted comprehensive information monitoring device, the locomotive vehicle-mounted comprehensive information monitoring device is connected with the vehicle-mounted antenna and the locomotive microcomputer display screen and used for sending the actual torque and the running speed of the motor to a server in an encrypted mode, and the server judges whether the torque of a traction motor exceeds a limit value or not according to the actual torque and the running speed, and sends the alarm information to the WEB client. The system is advantaged in that the system can remotely diagnose whether the motor exceeds the torque limit value or not in the using process and give an alarm, and great help is provided for motor fault analysis.
本发明提供了一种交流传动内燃机车牵引电机力矩超限值报警系统,包括服务器、WEB客户端、机车车载设备;所述机车车载设备包括车载天线、机车车载综合信息检测装置、机车微机显示屏、机车微机网络控制系统;所述机车微机显示屏与机车微机网络控制系统连接,接收并显示机车牵引电机实际力矩和机车运行速度并传输至机车车载综合信息监测装置;所述机车车载综合信息监测装置分别与车载天线、机车微机显示屏连接,用于将电机实际力矩和运行速度加密发送至服务器;所述服务器根据实际力矩和运行速度判断牵引电机力矩是否超限值,并向WEB客户端发出报警信息。本系统能够远程诊断电机在使用过程中是否超力矩限值并发出警报,对电机故障分析具有极大帮助。
