Intelligent traffic deceleration strip based on capacitance change

Abstract

A deceleration strip for intelligent transportation based on capacitance change relates to the technical field of intelligent transportation and comprises a road, and a T-shaped groove is formed in the top of the road. According to the intelligent traffic deceleration strip based on capacitance change, a piston block is matched with a rubber pad for use; when a vehicle slowly passes through the deceleration strip, the turbid liquid in the liquid storage tank is slowly stressed; at the moment, the piston block can slowly move downwards through the hydraulic principle; the contact area between the piston block and the turbid liquid is large, at the monment, the piston rod does not move downwards; when the piston block moves to the bottommost part, the dielectric plate can reduce the relativearea between the positive plate and the negative plate; the voltage of the circuit reaches the maximum access voltage of the piezoresistor, the top of the rubber pad and the road surface of the roadare at the same height, the turbid liquid becomes solid after being powered on, vehicles can pass through the turbid liquid conveniently, and therefore the effect of slow passing without vibration isachieved, the vehicle taking experience is remarkably improved, and safety of passengers and the vehicles is guaranteed.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a speed bump for intelligent transportation based on capacitance change. Background technique [0002] Speed ​​bumps are frequently used traffic aids on highways. They are mainly placed at intersections where vehicles need to slow down to remind vehicles to slow down. Many drivers deeply feel the damage caused by speed bumps, whether they pass through the speed bumps quickly or slowly. Passing through the speed bump at high speed will produce a strong vibration, which will reduce the driving experience. [0003] Most of the current deceleration belts are made of hard rubber, which has poor shrinkage. No matter passing through the deceleration belt at a slow or fast speed, there will be a sense of vibration. The vibration produced by fast passing is to remind the driver to drive safely, but when passing slowly The resulting vibration will not only reduce the co...

Problems solved by technology

[0003] Most of the current deceleration belts are made of hard rubber, which has poor shrinkage. No matter passing through the deceleration belt at a slow or fast speed, there will be a sense of vibration. The vibration produced by fast passing is to remind the driver to drive safely, but when passing slowly The shock generated will not only reduce the comfort of the people sitting in the car, but the strong shock will easily cause damage to the vehicle, easily cause traffic accidents, and seriously threaten personal safety. Therefore, a speed bump is urgently needed to reduce or avoid the shock
