Full-electronic turnout position detection device

Abstract

The invention discloses a full-electronic turnout position detection device. The device comprises a 110VAC reference signal circuit, a positioning detection circuit, an anti-position detection circuit, a normal indication relay and a reverse indication relay which are respectively connected with a forward direction drive circuit and a backward direction drive circuit. The 110VAC reference signal circuit comprises circuits X1, X2, X3, X4 and X5 connected with a switch machine, the positioning detection circuit is connected with the circuits X2 and X4, a diode is installed on the circuit X4, theanti-position detection circuit is connected with the circuits X3 and X5, a diode is installed on the circuit X5, the circuit X1 is connected with a fire wire, the forward direction drive circuit isconnected with a first processor, the backward direction drive circuit is connected with a second processor, and the normal indication relay and the anti-position indication relay are connected with the first processor and the second processor. By the combination of the outer switch machine and the diode, the detection of a position signal is achieved, and the circuit structure is simple.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a switch machine. Background technique [0002] The switch machine is an important executive device used in rail transit. It is used to turn the switch to switch and lock the switch point rail or core rail, and expresses the position and state of the switch point rail or core rail in the supervision interlocking area. Cut off the driving power of the point machine after the point machine is over-current or the turnout is in place, the point machine module enters the display circuit, and uploads the collected position status of the turnout. If the turnout is not locked, it will alarm in time and guide the safety side. [0003] There are two modes of operation for the switch machine: electric and manual. When the equipment is normal, it adopts electric mode to realize the fixed and reverse drive of the switch machine through the unified control of the switch controller; when...

AI Technical Summary

Problems solved by technology

[0005] 1. The specific signals used in the switch machine drive and switch position acquisition circuits need to be generated by special circuits, which increases the complexity of the circuits and also needs to ensure the reliability of the signals;

[0006] 2. The drive signal of the switch machine and the acquisition link of the switch position are long, and it needs to go through multiple modules (switch machine control module, execution input module, core processing module) to complete the judgment;

[0007] 3. The cabinet structure of the turnout control system is relatively large, takes up a lot of space, and has high hardware costs
