Detecting method for vehicle tire and detecting sensor

Abstract

The present invention discloses detection method and detecting sensor for vehicle tire. The detecting sensor includes lining, detection circuit board on the lining with electrodes, electrically isolating layer on the detection circuit board and with hole in the position corresponding to the electrodes, elastic conducting layer on the electrically isolating layer, and elastic casing on the elastic conducting layer and fixed on the lining. When no vehicle passes, the electrodes are in off state, and during vehicle passing, the conducting layer is pressed to turn on the electrodes and some signal is output. The present invention has simple structure, and can detect tire number by means of several detection circuits. The present invention may operate in harsh condition and is accurate and durable.

Description

technical field [0001] The invention relates to a sensor, in particular to a sensor and a detection method for vehicle tire detection. Background technique [0002] According to the requirements of the mandatory national standard GB1589-2004 "Outline Dimensions, Axle Load and Quality Limits of Road Vehicles", it is very important to correctly identify the number of vehicle tires in the road transport vehicle weight toll system and over-limit and overload detection system. Technology. [0003] The detection of the number of vehicle tires is essentially a detection device that detects the width of the tires through a certain number of sensors spaced at a certain distance and distributed perpendicular to the direction of driving. Currently widely used detection sensors include load cells, micro switches, photoelectric switches and proximity switches such as Hall switches. Its main defects are as follows: 1. The detection sensor uses the detection device of the load cell, has ...

Problems solved by technology

The biggest disadvantage is that it is not easy to detect low-speed moving objects (such as vehicles with a speed of less than 10 kilometers per hour), and cannot detect stationary or near-stationary objects (such as vehicles with a speed of less than 5 kilometers per hour)

[0004] In summary, due to the fact that the vehicle tire detection environment currently used is open 24 hours a day, and the interference effects of rain, ice, snow, sand and direct sunlight, etc., these detection sensors and devices installed with detection sensors inevitably have some insurmountable serious problems. Defects, which eventually lead to the failure of the detection function

The result is a low tire recognition rate, or even non-working
