A DC switch machine control system and control method

Abstract

The embodiment of the present invention discloses a DC switch machine control system and control method. In the control system, the interlock execution layer includes a rectifier for converting alternating current into direct current, and the interlock execution layer is connected to the AC power supply. The alternating current of the alternating current power supply is converted into direct current and input to the direct current switch machine. In this system, since the AC power supply cannot drive the DC switch machine, even if the device between the AC power supply and the DC switch machine fails, causing the AC power supply and the DC switch machine to be misconducted, the DC switch machine will not be caused by the uncontrollable power supply. The danger brought by the abnormal operation of the track machine ensures the safety of the circuit.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of switch machine control, in particular to a DC switch machine control system and control method. Background technique [0002] The electric switch machine is an electrical device used to control the rotation of the switch and detect the position of the switch. According to the driving power supply, it is divided into two types: DC electric switch machine and AC electric switch machine. At present, the commonly used DC switch machines mainly include ZD-6 DC electric switch machines, which adopt a four-wire interface. The four wires include a special line for rotation, a special line for indication, and a line for positioning, rotation and positioning. , a reverse rotation and reverse representation line. Its rated driving voltage is 160V DC and its current is 2A. [0003] In the all-electronic computer interlocking, or the electronic execution layer design of computer electronics...

Problems solved by technology

[0007] The present invention aims to solve the problem that the devices selected in the existing circuit for controlling the switch machine are easily broken down. Since the power supply is uncontrollable, the device may cause fatal danger after the device breaks down, and the circuit safety is not guaranteed.

[0008] On the other hand, the present invention solves the problem that the existing devices need to be replaced once they break down, the maintenance cost is too high, the traffic operation of the track line is affected, and the interlocking system for controlling the switch machine needs to be connected to the track through a long cable. The control of the switch machine next to it is easy to affect the control of the switch machine due to the fault of the cable
