A swing type pre-limit rod and a vehicle super-height detection method

Abstract

The invention discloses a swing type pre-limit rod, which is characterized in that the pre-limit rod comprises a column, a swing part and a swing sensor; The upright column is matched and fixed on theoutside of the channel; The swing part is arranged on the top of the column, horizontally arranged on the lower edge, extends over the channel and can rotate in the horizontal plane; The sensor is used for detecting a position change of the swing member. The invention not only reduces the damage of the vehicle, but also reduces the damage of the vehicle. And can be automatically returned and reused. It can detect the obvious displacement of the swing member, detect the vehicle collision swing member, judge the overheight of the incoming vehicle, and send a detection signal to the outside. Theutility model has the advantages of simple structure, reliable operation, long-term stable and reliable operation, low construction cost and low maintenance cost.

Description

technical field [0001] The present application relates to the technical field of channel traffic, in particular to a swing type pre-limit rod and a vehicle super-height detection method. 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 power produc...

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: the vehicle is damaged after colliding with the height limit pole; the height limit detection device is disposable (destroyed when it is too high), and cannot be detected before recovery; the height limit detection is inaccurate , there are deficiencies of missed detection and false alarms; when overtaking vehicles are detected, the reminder measures for the driver are not effective; the cost is high; there are deficiencies such as lack of measures to remind follow-up vehicles
