Automatic safety protection control system and method for railway crossing of metallurgical enterprise

Abstract

The invention relates to an automatic safety protection control system for a railway crossing of a metallurgical enterprise, and the system comprises a track circuit signal collector, a remote control host, a crossing controller and a crossing protection device; the track circuit signal collector and the crossing controller are in signal connection with the remote control host; the track circuit signal collector is used for collecting track circuit signals and turnout state signals and analyzing the signals to obtain condition instructions that a train approaches a crossing, and the crossing protection device comprises a crossing signal machine, a crossing barrier machine, an uplink proximity sensor, a downlink proximity sensor and a safety protection sensor. The crossing controller comprises a CPU module, a proximity sensor interface, a railway signal module and a safety protection module, the uplink proximity sensor and the downlink proximity sensor are both connected to the proximity sensor interface, the crossing signal machine is connected to the railway signal module, and the safety protection sensor and the crossing barrier machine are connected to the safety protection module. According to the invention, intelligent and automatic control of crossing protection equipment is realized.

Description

technical field [0001] The invention relates to the technical field of automation in metallurgical production, in particular to an automatic safety protection control system and method for railway crossings in metallurgical enterprises. Background technique [0002] The traditional railway crossing safety management mode in the factory is divided into two types: manned and unattended. Among them, the railway crossing in the metallurgical enterprise often adopts the manned mode because of the large traffic flow and the flow of people. Manned crossings are equipped with railway crossing signals and safety protection equipment such as telephones, wireless intercoms, crossing signals, fence machines, and proximity sensors in accordance with standard regulations. The crossings are closed / opened under the operation and management of crossing workers, and road crossings are guaranteed manually. The safety of vehicles and pedestrians and the smooth passage of trains through the cros...
