Embodiment 1

[0064] Example 1, see figure 1 , 2 , 3, 4, the electric locomotive maintenance operation safety monitoring system includes a monitoring machine 1, and the monitoring machine 1 is connected with the master station PLC module 2, and its feature is that it also includes the master station PLC module 2 through the field bus Connected to the communication module 3, the communication module 3 is connected to the PLC module 4 of the slave station, the ID card reader 5, the actuator 6 and the visual input and output system 7 are respectively connected to the PLC module 4 of the slave station, the actuator 6 and the roof image The camera 8 is correspondingly arranged on the column 10 on one side of the track 8 of the electric locomotive maintenance operation, and the roof image camera 8 is connected to the monitoring machine 1 through the video board 9 .

[0065] The monitoring machine 1 is a PC or an industrial computer. The model of the communication module 3 is EM 277. The communi...

Embodiment 2

[0091] Example 2, see Figure 5 , the control method of the electric locomotive maintenance operation safety monitoring system, if offline operation is selected, the operation steps are:

[0092] (1) Voice prompts to swipe the card for operation and maintenance;

[0093] (2), judging whether the receiving of the ID card number is completed, if completed, then enter the next step, if not completed, return to the previous step;

[0094] (3), input the locomotive number, and judge whether the locomotive number is input, if it has been input, then enter the next step, if not input, continue to input the locomotive number and continue to judge;

[0095] (4) The guardian obtains and judges the location of the locomotive, ID card number, extension number and locomotive number, if correct, then enters the next step, if not, returns to the first step;

[0096] (5) The guardian confirms whether the opening condition is satisfied, if it is satisfied, it will enter the next step, if not...

Abstract

The present invention relates to the technological field of operating safety network control of electric locomotive preparation, and in particular to an operating safety monitoring system of the electric locomotive preparation. The monitoring system comprises a monitoring machine (1) which is connected with a main station PLC module (2); the main station PLC module (2) is connected with a communication module (3) through a field bus; the communication module (3) is connected with a slave station PLC module (4); an ID card reader (5), an actuator (6), and a visualized input and output system (7) are respectively connected with the slave station PLC module (4); the actuator (6) and a vehicle roof image camera (8) are correspondingly arranged on a standing column (10) which is arranged on one side of a track for the electric locomotive preparation; the vehicle roof image camera (8) is connected with the monitoring machine (1) through a video board card (9). The monitoring system greatly shortens the time of preparation, improves the working efficiency, guarantees the personal safety of the repairing personnel of the vehicle roof and the safety of the equipment, and reduces the hidden danger which results from insecure factors in the operating process.

Description

Technical field: [0001] The invention relates to the technical field of electric locomotive maintenance operation safety network control, in particular to a safety monitoring system for electric locomotive maintenance operation. Background technique: [0002] After electric locomotives (including EMUs) return to the depot each time, they must be reconditioned in the section. During the maintenance operation, the work area must be an isolated non-electric area, that is, the catenary with a rated voltage of 27.5KV is disconnected through the isolating switch before the maintenance operation, and another ground wire is connected. [0003] In the prior art, the isolation switch, the operation of the grounding wire and the safety monitoring link in the maintenance operation process of the electric locomotive have been operated manually since the operation of the electrified railway in my country. First of all, the locomotive to be prepared must stop before entering the isolation...
