Monorail turnout position switch rapid detection device and detection method thereof

Abstract

The invention relates to a monorail turnout position switch rapid detection device and a detection method thereof. The device comprises a connecting unit, a detection unit, a signal processing unit and a display unit. The connecting unit is connected with the position switch and the detection unit; the signal processing unit is connected with the detection unit and the display unit; the detectionunit comprises a bridge, a direct-current high-voltage generator, a leakage current tester, an analog quantity input module, a digital quantity input module and a first PLC. The electric bridge is electrically connected with the connecting unit, the analog quantity input module and the first PLC; the direct-current high-voltage generator is connected with the connecting unit and the first PLC; theleakage current tester is connected with the connecting unit, the analog quantity input module and the first PLC; the analog quantity input module is connected with the first PLC; the digital quantity input module is electrically connected with the connecting unit and the first PLC; and the first PLC is connected with the signal processing unit. The device can realize detection of a plurality ofdominant faults and recessive faults of the position switch, and can output a result in real time.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and in particular relates to a quick detection device and a detection method for a switch position switch of a single track. Background technique [0002] Monorail transportation in the field of rail transportation has become an important means of transportation for people to go out. In the traffic organization of monorail traffic, in order to meet the needs of vehicles changing lanes, it is necessary to set up monorail switches to realize the lane changing of vehicles between different tracks. In the operation process of a single track switch, multiple mechanisms are often required to complete the line change operation. Each mechanism is equipped with several position switches as detection equipment in the mechanism motion control to ensure that each mechanism of the turnout operates according to the predetermined position or stroke. , stop or limit protection. [0003] Under the existing...

Problems solved by technology

Although this method can judge the state of the position switch to a certain extent, it depends on the experience and proficiency of the maintenance personnel, has certain uncertainty, and the inspection is not comprehensive enough, the efficiency is low, and the performance of the position switch is reduced. It cannot be found, and can only be repaired after the position switch fails, which is not conducive to the safe and reliable operation of the turnout, and has a certain adverse effect on the normal operation of monorail traffic; while the existing position switch detection device has a cumbersome mechanism, single function, and cannot be used. Quick inspection of the position switch at the single track switch site
