On-line Monorail Pantograph Monitoring System

Abstract

The invention discloses an online monorail car pantograph monitoring system which comprises a detection box body arranged on a steel rail, a bending contact line, a programmable logic controller (PLC), a double ultrasonic detection device, a photoelectric switch, a lateral contact pressure measurement device, a pantograph detection device and an automatic switch protection door. The system is ingenious and reasonable in design, the wrong vehicle information extraction is effectively avoided by employing the design of the double ultrasonic probes, wrong judgment is avoided, and the smooth operation and safety of rail transit is ensured. The bending contact line has the bending structural design, and the abrasion conditions of the sliding plate are conveniently, clearly, intuitively and accurately obtained; the whole detection process of the lateral contact pressure measurement device is rapid and flexible, and the measurement accuracy and stability of the product are wholly improved; and moreover, the automatically opened / closed protection door can open or close the detection window, waterproof, dustproof and other functions are realized on the basis that the detection vision field of the detection equipment is not blocked during operation, and normal operation of the detection equipment is guaranteed.

Description

technical field [0001] The invention relates to monitoring system technology, in particular to an online monorail vehicle pantograph monitoring system. Background technique [0002] During the operation of the light rail, the light rail train takes power through the contact between the sliding plate on the pantograph and the contact wire, which is used as the traction power supply of the light rail train and the power supply of other electrical equipment. In the high-speed electrified light rail train line system, the light rail train must maintain a stable state of flow. Therefore, as the key current-taking equipment directly in contact with the contact line, the state of the pantograph slide is extremely critical, and it is related to whether the locomotive can take power from the contact line stably and reliably. Due to the long-term contact between the pantograph slide plate and the contact wire, wear and tear will inevitably occur, resulting in poor electrical performa...

Problems solved by technology

[0005] However, since the existing contact lines are all linear, it will partially block the skateboard, that is, there are omissions, which cannot be fully observed, and it is easy to cause misjudgment
