Abstract

The invention discloses a computer interlocking system and a working method thereof, wherein the computer interlocking system comprises an interlocking machine, a communication gateway and a turnout, signal and railway execution unit; the signal execution unit comprises a signal lamp control unit, a protective unit and a signal acquisition unit, wherein the protective unit comprises a logic protection unit and a signal safety relay, the logic protection unit receives first signal state information and second signal state information respectively output by a first signal controller and a second signal controller, and the first signal controller, the second signal controller and the logic protection unit all receive system feedback information acquired by the acquisition unit; the first signal state information, the second signal state information and the system feedback information are logically compared by the logic protection unit through hardware, and a signal lamp abnormal signal for controlling the signal safety relay is output according to a comparison result; and under the condition that the signal lamp abnormal signal is output, the signal safety relay is only controlled by the signal lamp abnormal signal, so that the signal execution unit is led to be safe from faulty.

Description

technical field [0001] The invention relates to a computer interlocking system for a station and a working method thereof, in particular to the improvement of a signal execution unit for controlling the display of a signal machine in the computer interlocking system. Background technique [0002] The current computer interlocking system generally includes an interlocking machine and a communication gateway, as well as a turnout execution unit, a signal execution unit, a track execution unit, and a scattered execution unit controlled by the interlocking machine, wherein the turnout execution unit is responsible for controlling the switch machine Drive the turnout for fixed operation and anti-operation positioning; the signal execution unit is used to control the display of the shunting signal machine and the signal machine entering and leaving the station, that is, to control the display of various signal lights; the track execution unit is the lowest track state acquisition u...
