Problems solved by technology

However, when driving at night or in foggy weather, it is difficult for the driver to ensure the safe running of the tram. At the same time, the train driver must always be alert to the occurrence of traffic jams, speeding, rushing, and too close to each other during the operation. Various dangerous emergencies, if things go on like this, will inevitably cause driver fatigue driving, and there is currently no stable and reliable technology or system that can solve this problem

Embodiment Construction

[0045] First of all, in this embodiment, the present invention provides a tram safety detection and early warning system. For details, please refer to figure 1 , is characterized in that, comprises train positioning equipment, radar, line database, control center, vehicle-mounted control host computer and audible and visual alarm, and train positioning equipment, radar, vehicle-mounted control host computer and acousto-optic alarm are all arranged in the train.

[0046] Train positioning equipment is used to detect train position information and driving status information.

[0047] The radar is a millimeter-wave radar, installed horizontally on the front of the train, and used to detect the status of obstacles in front of the train. The obstacles in front include stationary obstacles, pedestrians and vehicles. The detection range of the millimeter-wave radar is as follows: image 3 As shown, it has the ability to detect up to 200 meters.

[0048] The line database transmits l...

Abstract

The invention provides an early warning system and method for tram safe driving detection. The system can detect a front obstacle of a tram in real time and classify the risk grades of line invading obstacles; when the system detects a near obstacle, the system can conduct early warning for a driver to slow down so as to achieve safe driving. Meanwhile, the system can conduct early warning processing on splitting-of-point accident, train overspeed, train premature advance, over-close train distance and other faults which hazard traffic safety, inform the driver of fault information in advance,and remind the driver to drive carefully so as to ensure the safe operation of a train; the system has the advantages of being good in human-machine interface, simple, clear, easy to understand and easy to operate; under heavy weather conditions such as heavy fog and heavy rain, the system can also ensure the safe and reliable operation of the train, and the system achieves the detection and early warning function to the front dangerous working condition of the tram, and effectively relieves the driver's driving fatigue symptoms.

Description

technical field [0001] The invention relates to the technical field of safe running of trams, in particular to a detection and early warning system and method for safe running of trams. Background technique [0002] Tram safety detection and early warning is an emerging technology hotspot. It is different from the operating environment of independent road rights such as subways and high-speed rail. In order to ensure the safe driving ability of modern trams under mixed road rights, train drivers need to observe in real time In the road ahead, if you find an obstacle encroaching on the line, you need to slow down in advance to prevent accidents. However, when driving at night or in foggy weather, it is difficult for the driver to ensure the safe running of the tram. At the same time, the train driver must always be alert to the occurrence of traffic jams, speeding, rushing, and too close to each other during the operation. Various dangerous emergencies, if things go on like ...
