Problems solved by technology

The defect of the GPS differential positioning system is that its positioning accuracy will be interfered by factors such as weather and electromagnetic environment. Under harsh conditions, the positioning error can be more than 4 meters, which is likely to cause the control center to give wrong instructions
The sensor positioning system installs a sensor on each signal machine and a ground transponder on each channel. The transponder needs to be powered from the signal machine through a wired method. The construction is very complicated, and the workload of later maintenance and repair is also very large.

Abstract

The invention discloses an overrunning prevention system and an overrunning prevention method for locomotive propulsion. The system comprises passive radio frequency identification tags, train head equipment, locomotive equipment, a ground control center and portable control equipment, wherein the passive radio frequency tags can be used for storing position information; the train head equipment can be used for reading the position information in the ground tags, and transmitting the position information through a wireless link; the locomotive equipment can be used for receiving and forwarding the position information, receiving control signaling, and executing corresponding operation; the ground control center can be used for acquiring the statuses of signal lamps, receiving the position information from the locomotive equipment, and querying the status of the signal lamp of a track where a locomotive is located according to the position information to determine whether to transmit an alarming signal to the locomotive equipment or not; the portable control equipment can be used for receiving the alarming signal forwarded by the locomotive equipment, and transmitting a control instruction input by an operator to the locomotive equipment through the wireless link. The overrunning prevention system is high in positioning accuracy and low in mounting and maintenance cost, and can also be used for automatically controlling overrunning in case of an emergency, so that the shunting propulsion running safety is greatly improved.

Description

technical field [0001] The invention relates to the field of railway control, in particular to a railway shunting operation control system. Background technique [0002] Most of the current shunting operations use the traditional shunting system. During the train advancement process, the connector observes the status of the front signal light (installed on the signal machine), and then manually sends instructions to the shunting operator to control the train to advance or stop. If the wrong signal is given by the operator due to negligence or obstruction of vision due to bad weather, the locomotive will take off and cause serious damage. [0003] At present, there are some relatively advanced shunting systems at home and abroad. In these shunting systems, a special positioning system is used to locate the position of the locomotive, and then the control center issues instructions to the shunting staff according to the position of the locomotive and the status of the signal l...
