Detection tool for ATC system

Abstract

The invention discloses a detection tool for an ATC system. When voltage values of various interface point locations of a connecting device are measured, an external connector of the tool is in matched connection with the connecting device, various connecting noodles of the external connector are correspondingly inserted into the interface point locations of the connector, and measurement circuitscorresponding to the interface point locations one to one can be formed. Switches on the measurement circuits are turned on / off in sequence, the measurement circuits are switched on in sequence, andthen the voltages of the interface point locations are measured through voltmeters in sequence. According to the detection tool for the ATC system, through automatic matching and reliable connection of the external connector and the connecting device, errors caused by human factors in the detection process are greatly avoided, and the detection reliability is improved. The electric shock risk existing in the detection process is avoided, and the test safety factor is improved. Besides, in the way of adding the switches to the measurement circuits, it is convenient for a tester to carry out anexperiment, the detection operation is simple and convenient, and the detection efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of ATC detection, in particular to an ATC system detection tool. Background technique [0002] ATC (Automatic Train Control) is called the automatic train control system. It is mainly composed of three parts: ATS (Automatic Monitoring System), ATP (Automatic Protection System) and ATO (Automatic Operation System). This system is mainly used to control the safe operation of trains. Today It has been widely used in the subway lines of various cities in our country. [0003] The ATC system is one of the more important systems in the operation phase of the subway vehicle, so the inspection and debugging of the ATC system is particularly important. At present, the detection and debugging of the ATC system are realized by detecting the corresponding hardware equipment, that is, after performing corresponding operations, the voltage detection is performed on the corresponding connector interface points on the cont...

Problems solved by technology

The existing detection method is manual measurement with a multimeter, which requires three operators to operate at the same time, one person is responsible for operating and recording the experimental data, one person is responsible for operating the positive test lead of the voltmeter to connect it to the point to be measured, and the last person is responsible for the voltage. Connect the negative meter lead to the negative line and observe the voltage indication at the same time. This detection method is time-consuming and labor-intensive. During the operation, it is prone to misconnection, measurement error, electric shock, etc., which makes it difficult to guarantee the quality and efficiency of the automatic train control system test.

[0004] Therefore how to solve the time-consuming, laborious and low accuracy problems of ATC system detection is a technical problem that those skilled in the art need to solve at present
