Abstract

The embodiment of the invention discloses an image-based train safe operation control system and method. The system comprises a vehicle-mounted device; the vehicle-mounted equipment comprises a vehicle-mounted image recognition module; the ground equipment comprises a trackside occupation identification module and a safety processing center; the safety processing center is configured to obtain the position information of the current train, the position information of the front train of the current train and the occupation condition of each section in the route direction of the current train; determining an authorization terminal point of the current train according to the position information of the current train, the position information of the front train of the current train and the occupation condition of each section in the route direction of the current train; and controlling the operation of the current train according to the authorized terminal point of the current train and the operation parameters of the current train. According to the system, no matter whether the route direction of the current train is occupied or not, safe operation of the current train can be ensured, so that traffic accidents can be avoided, and reliable and safe operation of the train is ensured.

Description

technical field [0001] The embodiments of the present invention relate to the field of railway signal control in rail transit, and in particular to an image-based system and method for controlling safe operation of trains. Background technique [0002] The current rail transit operation control system mainly realizes the interval control of train tracking intervals and overspeeding, etc., but the safety of personnel and the safety protection of the trackside are not included in the scope of railway signal safety protection. The side foreign matter invades the limit and causes a train accident. At the same time, with the rapid development of image technology and computer technology, the train control system based on image perception technology will become the future development direction, and can greatly simplify the number of trackside equipment and on-board equipment in the traditional train control system, simplify the system structure, It reduces the maintenance workload...
