Description

Vehicle-mounted subway door V degree monitoring device Technical Field The utility model relates to the technical field of subway door detection, in particular to a vehicle-mounted subway door V degree monitoring device. Background With the rapid development of urban rail transit, the safety reliability and reliability of subway door systems are increasingly emphasized. The subway door is used as an important channel for passengers to get on or off the train, and the normal operation of the subway door directly relates to the safety of the passengers and the normal operation of the train. At present, the state identification of the door leaf of the vehicle door mainly carries out data monitoring from two aspects of vehicle-mounted door controller detection and vehicle section field periodic inspection. The vehicle section field periodic inspection is to measure the V degree of the vehicle door manually by a tape measure, so as to identify the door state, and repair the vehicle door with abnormal data by manually adjusting the mechanical structure of the vehicle door. In actual measurement, a tape measure is mostly used for measurement, the measured value can be calculated to obtain the V-degree size of the door page, and because the machine measurement depends on the hand feeling and experience of operators, single debugging parameter results often cannot meet the specifications, so that repeated measurement is required to be slower, the measuring accuracy of the tape measure is lower, and the error is larger.
