Height-limiting rod anti-collision warning device and method employing crash sensor

Abstract

The application discloses a height-limiting rod anti-collision warning device employing a crash sensor. The device comprises a height-limiting rod, a pre-limiting rod arranged in front of the height-limiting rod, crash sensors and a control module arranged on the pre-limiting rod, and a warning device arranged on the height-limiting rod, a first crash sensor and the warning device are connected with the control module through a signal line or a wireless control module, a function of warning drivers of over-limit vehicles is provided, when the front vehicle exceeds the height, the driver of thefront vehicle is reminded to take brake measures and the driver of the rear vehicle is reminded to improve alert, and when the driver of the over-limit vehicle collides with the height-limiting rod due to failure of timely control of the vehicle, evidence can be taken in time, and the emergency is informed of a traffic accident police-calling station to facilitate subsequent processing. Accordingto the device, the structure is simple, the practicality is high, the accuracy is high, the work is reliable, the cost is low, function improvement of the conventional height-limiting rod on the roadcan be performed to achieve the goal of the device, and the material is saved.

Description

technical field [0001] The present application relates to the technical field of road traffic, in particular to a height limit pole anti-collision warning device and method using a collision sensor. Background technique [0002] On urban and rural roads, it is a common phenomenon in the whole country to set up height limit poles for the purpose of protecting bridges, culverts or weight limit. But every once in a while, there will be so many reports on the news that trucks, trucks, and even buses hit the ceiling poles, and in severe cases, the cars were destroyed and people died. The function of the height limit pole is intended to warn vehicles not to pass at super heights. This kind of warning does not have to be at the cost of car crashes. [0003] The Chinese patent "Intelligent Road Height Limit Anti-collision Warning Device in Power Production Area" (authorized announcement number CN105160936B) provides an intelligent road height limit anti-collision warning device in ...

Problems solved by technology

[0005] Chinese patent CN201120327833.0 discloses a powder-type insulated high-speed micro-collision switch, which can effectively solve the problems of existing glass mercury switches with large volume, blind spots in work, and unstable consistency and repeatability. The technical solution is, It includes a closed cavity, mercury and an insulating frame. There is a closed cavity on the insulating frame. There are first electrodes and second electrodes extending out of the frame and insulated from each other in the frame. The contacts of the first electrode and the second electrode are connected to the The cavity is connected, the cavity is filled with mercury, and a layer of insulating powder is adsorbed on the inner surface of the cavity and the mercury. This utility model is compact in structure, small and unique, easy to use, reliable and stable in operation, and is an innovation in microelectronic switches.

[0008] Existing anti-collision devices for height limit poles have problems including: inaccurate height limit detection, defects of missed detection and false alarms; height limit detection devices are disposable (destroyed when super high), and cannot be detected before recovery ;When overtaking vehicles are detected, the reminder measures for the driver are not effective; the cost is high; there are defects such as lack of measures to remind follow-up vehicles
