Automatic split phase passing ground sensing device detection system

Abstract

The invention discloses an automatic split phase passing ground sensing device detection system which comprises a magnetic field detection probe (2), a camera (3), a control box (4) and an industrialpersonal computer (5). The magnetic field detection probe (2) and the camera (3) are mounted on the left side and the right side of the outside of a train (1), and the control box (4) and the industrial personal computer (5) are mounted inside the train (1); the magnetic field detection probe (2) is connected with the control box (4) by RS385 bus, the control box (4) is connected with the camera (3) by a power line and is connected with the industrial personal computer (5) by RS232 bus, and the industrial personal computer (5) is connected with the camera (3) by a network cable. The automaticsplit phase passing ground sensing device detection system has the advantages that magnetic fields of a ground sensor can be dynamically measured by the magnetic field detection probe; images of the ground sensor can be acquired by the camera; the appearance and the performance of the ground sensor can be detected, accordingly, substandard ground sensors can be timely discovered, electrified splitphase passing accidents due to problems of the ground sensors can be effectively prevented, the reliability of automatic split phase passing systems can be improved, the operation intensity can be relieved for field staffs, and the operation difficulty can be lowered for the field staffs.

Description

technical field [0001] The invention belongs to the technical field of automatic phase separation function detection of electric locomotives, in particular to a detection system for an automatic phase separation ground induction device. Background technique [0002] The electrified railway grid adopts single-phase power supply, while the power system is a three-phase power supply system. In order to make the electrified railway take current from the three-phase grid of the power system basically symmetrical, the electrified railway adopts the method of taking current by phase separation and segmentation, that is, a phase separation area is set every 20-25km, and adjacent phase separation areas are composed of two phases of different phases. There is a power supply dead zone of about 30m in the adjacent phase-splitting area, so there is a problem of how the electric locomotive passes through the phase-splitting area. In order to prevent short circuit between phases, the "aut...

Problems solved by technology

The existing automatic detection equipment for the automatic phase separation system is aimed at the detection of the vehicle-mounted part, that is, the induction receiving device and the control system. For the detection of the ground induction device, at present, manual detection is carried out regularly to each phase separation point with magnetic field measurement equipment. There are many problems such as high strength, long detection cycle, the accuracy of detection data is affected by human operation, inconvenient test data concentration, and inconvenient tracking and analysis. Feedback from the job site urgently needs an automatic measurement device to solve this problem.
