Abstract

The invention discloses a turnout control system which comprises multiple position switches, a switch frequency converter, a corresponding switch motor, an on-off reverser, a corresponding on-off motor and a PLC device. The PLC device comprises a control module, a fault detection module and an HMI display screen, wherein the control module is used for controlling the switch frequency converter todrive the switch motor to act and controlling the on-off reverser to drive the on-off motor to act in a preset control mode; the fault detection module is connected with the multiple position switchesand used for detecting whether the multiple position switches are disconnected or not and generating corresponding disconnection fault information if disconnection occurs; and the HMI display screenis connected with the PLC device through an industrial Ethernet and used for displaying state information of the turnout control system in real time, wherein the state information comprises the disconnection fault information. The turnout control system is simple in control circuit, high in control reliability and long in service life.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a turnout control system. Background technique [0002] At present, in the logical control of the turnout, the control part mainly uses safety relays, time relays, etc. The extensive use of relays and time relays makes the connection lines of the control system more complicated, and arcs and mechanical wear may occur when the contacts are switched on and off, which affects the life of the relays and has poor reliability. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the above-mentioned technologies at least to a certain extent. For this reason, the object of the present invention is to propose a kind of switch control system. The system can improve the reliability of the switch motion control, and has simple control circuit and long service life. [0004] In order to achieve the above object, the embodiment of th...
