An intelligent tester for track circuit shunt parameters and its implementation method

Abstract

The invention relates to an intelligent track circuit shunt parameter tester and a test method thereof. The intelligent track circuit shunt parameter tester comprises a hand-held tool that matches the shape of the surfaces of steel rails and a test instrument that is connected to a contact copper board of the hand-held tool via a copper wire. The hand-held tool has three parts, namely, an integrated outer sheath with a handle, the contact copper board with the same arc shape as the surface of the steel rails and a rust-removing filing board. The copper wire is led out from the contact copper board of the hand-held tool. The instrument is arranged in a customized housing. Two copper pillars are installed at the top of the housing and are connected to the copper wire on the back of the housing. After the instrument is mounted in the housing, shunt electrical signals can be effectively obtained through the two copper pillars, and calculation is automatically carried out according to the electric signals. The technical scheme provided by the invention can solve the problem of poor contact of the tester which may be caused due to corrosion of the steel rail, and the rail surface voltage between the two steel rails and the shunt current after the two steel rails are shunted can be measured efficiently and conveniently.

Description

technical field [0001] The invention relates to a track circuit tester, in particular to an intelligent tester for track circuit branch parameters and a realization method thereof. Background technique [0002] The track circuit is a circuit composed of the track circuit system equipment and the rail line. The track circuit system equipment forms a complete circuit through the rail line, and the track circuit signal is transmitted to the train through the rail to control the train to run at different speeds on the railway line. or parking. [0003] In order to ensure that the track circuit signal can be reliably received by the train, it is very necessary to test the track circuit signal on the rail line. The track circuit signal test on the rail line mainly includes the rail surface voltage test between two rails and the shunt current test after the two rails are split. [0004] At present, there are two main problems in the test of track circuit parameters: 1. Because th...

Problems solved by technology

[0004] At present, there are two main problems in the test of track circuit parameters: 1. Since the rail line is exposed to the air, the surface is oxidized and corroded, so the test results are often inaccurate during the track surface test or branch test; 2. .The shunt resistance between the two rails is 0.15Ω or 0.25Ω according to the railway standard. The current shunt test tooling is simple and the resistance value error is large, which is difficult to meet the standard requirements, and the operation is inconvenient, the work efficiency is low, and the test accuracy is low.
