Train obstacle detection and comprehensive early warning protection system

Abstract

The invention discloses a train obstacle detection and comprehensive early warning protection system. The system comprises a radio wave communication ranging device, a laser radar detection device, avisual detection and analysis device, a contact type obstacle and a derailing detection device. The radio wave communication ranging device, the laser radar detection device and the visual detection and analysis device are mounted on the head of a train, and the contact type obstacle and the derailing detection device are mounted at the bottom of the head of the train. The radio wave communicationranging device, the laser radar detection device, the visual detection and analysis device, the contact type obstacle and the derailing detection device send acquired or detected data to a system host, and the system host receives data and transmits the intelligently-analyzed data to a man-machine interaction terminal. According to the train early warning protection system, a multi-sensor communication detection measure in which a non-contact manner and a contact manner are combined is adopted, other trains, obstacles and people are detected in an omni-bearing manner from a far distance to aclose distance to contact, other manners can continue to be used for detection under the condition that one detection manner fails, and the operation safety of the train is guaranteed.

Description

technical field [0001] The invention relates to the field of train anti-collision early warning, in particular to a train obstacle detection and comprehensive early warning and protection system. Background technique [0002] With the rapid development of the national economy, the demand for rail transportation is increasing. With the improvement of transportation efficiency requirements, sometimes the ATP automatic protection system must be cut off in actual operation. In this case, the traditional blocking method cannot ensure the safety of transportation. For train collision avoidance, there are currently some solutions, but most of them are early warning methods of a single signal source. Because the current rail transportation environment is complex, and the satellite positioning of entering and exiting tunnels is often inaccurate, and the coverage of traditional communication signals is not comprehensive. Therefore, there are bound to be many blind spots in a single...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that the existing single signal source early warning method for train collision avoidance mostly has many blind spots, and the contact detection method is used for obstacle detection. When an obstacle is detected, the accident has occurred. The purpose is to Provides a train obstacle detection and comprehensive early warning and protection system, which uses a variety of sensor communication detection methods combining non-contact and contact, to detect other trains and obstacles in an all-round way from long-distance to short-distance and then to contact When one of the detection methods fails, the detection can be continued by other methods, which ensures the safety of the train operation, and can also detect and deal with it in time when the train derails.
