Embodiment Construction
[0029] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0030] Refer to attached figure 1 , System structure introduction: Taking a two-way intersection as an example, the possible collision positions of vehicles in the intersection are four intersection conflict points in the intersection. Taking the direction from east to west as an example, vehicles in this direction may collide with vehicles traveling from south to north at point P1, and may also collide with vehicles traveling from north to south at point P2, because the position of point P1 is from east to west The earliest possible collision point for vehicles in the west direction, here we define point P1 as the "most dangerous point" in this direction. The definitions of P2, P3, and P4 are similar. The speed measuring position and early wa...

The invention discloses a signal-control crossroad vehicle collision avoidance pre-warning system. The signal-control crossroad vehicle collision avoidance pre-warning system comprises three modules which are an information collecting module, an accident judging module and an accident pre-warning module. In information collection, a laterally-installed microwave detector is mainly adopted to carry out vehicle-speed collection, a single-chip microcomputer is used for processing speed signals and making right judgment for vehicles possible to collide, and finally an LED electronic displayer and a lamp flicking device are used for carrying out accident pre-warning. The signal-control crossroad vehicle collision avoidance pre-warning system is reasonable in design, the anti-collision pre-warning function is added on the basis of a vehicle-speed measuring technology in the prior art, the signal-control crossroad vehicle collision avoidance pre-warning system effectively supplement traffic lamps and only warns when possible collision is detected, and therefore the signal-control crossroad vehicle collision avoidance pre-warning system is good in pre-warning effect for a road user, and has a certain effect on reducing accident rate of a crossroad.
Description
technical field [0001] The invention relates to a vehicle anti-collision early warning system, in particular to a signal control vehicle anti-collision early warning system at an intersection. Background technique [0002] There are many types of accidents at intersections, among which traffic accidents between vehicles are more common, and the accident rate is higher at night. Such accidents are generally accompanied by traffic violations, mainly for running red lights and speeding. [0003] my country's current preventive measures for traffic accidents at intersections are mainly reflected in the following aspects: (1) laws and regulations; (2) traffic signs and markings; (3) signal control measures. [0004] However, the above-mentioned measures will depend on the premise that the driver abides by the traffic rules, and they cannot play a role for drivers who are lucky. For example, when there is less traffic at night, the phenomenon of drivers speeding and running red ...
