Locomotive position monitoring and safety controlling device based on track circuit and control method thereof

Abstract

The invention relates to a locomotive position monitoring and safety controlling device based on a track circuit and a control method thereof. The device comprises a fixed device and a vehicle-mounted device. The fixed device comprises a communication server, a centralized traffic control main machine, a data radio station base station, a global position system (GPS) time service device and a computer interlock system. The vehicle-mounted device comprises a safety control main machine, a vehicle-mounted data radio station, a vehicle-mounted GPS time service device, a display, an alarm voice box, a braking device and a sensor. Based on the devices and a current industrial site computer interlock system, the locomotive position monitoring and safety controlling device based on the track circuit and the control method thereof achieve real-time calculation for an accurate position where a locomotive runs on a railway through utilizing the occupied and idle time of the track circuit and according to the collected running speed of the locomotive, can predict whether the locomotive runs on the basis of observing regulations according to the position and by referring to the conditions of a signal machine, a track switch and other signal devices, and carries out early warning and braking before violation of the regulations. Accordingly, the purpose of guaranteeing safe driving is achieved.

Description

technical field [0001] The invention relates to the technical field of locomotive position detection and driving safety control, and discloses a locomotive position detection and safety control method based on a track circuit. Background technique [0002] At present, the railway track on the industrial site is electrically composed of multiple sections, each of which is called a track section, and each section of the track section has a track circuit detection device for detecting whether the locomotive is pressed on the section. When the locomotive is running on the railway, the matching computer interlocking system can detect that the locomotive is in a certain section in real time through the track circuit detection device, and then control the signal machine in the station to display different modes according to the signal interlocking rules. The driver of the locomotive drives according to the display mode of the signal machine, so as to achieve the purpose of safely d...

Problems solved by technology

[0004] For the positioning method using GPS, the position of the locomotive can be easily located, but when the locomotive is operating inside the factory building, the GPS device will not work, and there are certain shortcomings. At the same time, considering the cost, power supply, and maintenance convenience, etc., Usually the GPS positioning equipment is only installed inside the locomotive head, not on the wagon skin, so that it can only locate the position of the locomotive head, but cannot locate the position of the rear of the car where the carriage is articulated, nor can this method be used to detect a train of locomotives In this way, it is difficult to realize the safety protection function when the locomotive is carrying out jacking operations, and it is impossible to achieve active protection against illegal driving such as speeding and running red lights.

[0005] For the method of adding a point transponder, it is necessary to install a card reader on each locomotive head, and install a point transponder at a specific position on the
