Problems solved by technology

Taking a train of 6 trains as an example, there are 20 current collectors on both sides of the vehicle. The measurement process takes about 40 minutes by 2 people (1 person for measurement and 1 person for recording), which is very time-consuming, wastes human resources, and is cumbersome to record. Error-prone, due to manual measurement, measurement accuracy cannot be guaranteed

Abstract

The invention relates to an online intelligent detection system for pressure of a current collector for rail transit, which belongs to the technical field of rail transit detection devices. The systemcomprises an upper computer placed on a DCC of a vehicle depot and a lower computer in two-way communication with the upper computer through a wireless communication module, and the lower computer isfixed to one side of a station track; detection devices are installed on the two sides of the station track in the direction of the warehouse-out end of a vehicle depot application warehouse respectively, each detection device comprises a contact rail and a pressure sensor, a movable face is arranged on the contact face of each contact rail, and the back of each movable face is connected with thecorresponding pressure sensor to form an acquisition channel. the upper part, the side part or the lower part of each contact rail is in contact with the current collector; the pressure sensor is indynamic contact with the current collector and transmits an acquired current collector pressure signal to the lower computer; and the lower computer stores the processed data in an SD card and transmits the processed data to the upper computer through the wireless communication module. The pressure sensor with higher precision is adopted, the pressure value of the current collector can be intelligently and automatically measured, and manpower is greatly saved.

Description

technical field [0001] The invention relates to an online intelligent detection system for the pressure of a current receiver used in rail transit, and belongs to the technical field of rail transit detection devices. Background technique [0002] In addition to pantograph-catenary way, electric-driven rail vehicles can also receive power from the third rail through the current collector installed on the bogie. According to the vehicle maintenance regulations, subway vehicles must measure, record and archive the pressure value of the current collector regularly, and adjust the current collectors that are not within the standard range to ensure that the vehicle has good current receiving performance. The traditional measurement method adopts the manual way to measure the receivers one by one, the measuring tool is a spring pressure gauge, and records one by one. Taking a train of 6 trains as an example, there are 20 current collectors on both sides of the vehicle. The measur...
