A safety interlock system for locomotive maintenance work

Abstract

The invention discloses a safety interlock system for a servicing work of an engine. The safety interlock system for the servicing work of the engine comprises a disconnecting switch controller, an automatic grounding device, an automatic electricity tester, an engine guide device, a video monitoring device, a PLC (Programmable Logic Controller) sub station, a PLC master station and a monitoring center. The safety interlock system for the servicing work of the engine provided by the invention prevents accidents caused by personal factors such as negligence and lassitude of essence-spirit of workers by various means such as remote control of the disconnecting switch, automatic electricity test, video monitoring and estimation and the like, and meanwhile realizes synchronous joint operation of field staff and staff in a dispatching room through the monitoring center, thereby shortening the overhauling time and improving the overhauling efficiency of the engine.

Description

technical field [0001] The invention relates to the field of locomotive maintenance operation safety, in particular to a safety interlocking system for locomotive maintenance operation. Background technique [0002] Locomotive maintenance operation is an important part of locomotive operation and maintenance. It has the characteristics of frequent locomotive entry and exit, high maintenance operation density, and three-dimensional crossover. Putting into use a good technical state has become one of the key points of railway work. At present, the safety monitoring of locomotive maintenance operations is generally done manually, and the supervisors need to be highly alert 24 hours a day, paying attention to the closure of the isolating switch, the operation of the operators on the three-story platform, and the raising of the pantograph on the roof. Landing situation, the entire monitoring process is extremely time-consuming and energy-consuming, and a slight negligence will c...

AI Technical Summary

Problems solved by technology

At present, the safety monitoring of locomotive maintenance operations is generally done manually, and the supervisors need to be highly alert 24 hours a day, paying attention to the closure of the isolating switch, the operation of the operators on the three-story platform, and the raising of the pantograph on the roof. Landing situation, the entire monitoring process is extremely time-consuming and energy-intensive, and a slight negligence will cause personal injury accidents

Moreover, since the isolating switch is manually operated, once an abnormal situation occurs in the isolating switch, it is very easy to cause personal injury accidents.
