Abstract

The invention provides a digital axle recognizer. The digital axle recognizer comprises a metal section, a recognizer cavity and multiple piezoelectric sensors equidistantly encapsulated in the recognizer cavity, the inner portion of the recognizer cavity is provided with a circuit board fixing element, the fixing element is provided with a circuit connecting board, the circuit connecting board isa block welding board, and the piezoelectric sensors are electrically connected with the circuit connecting board; the metal section is provided with a left end soft sealing plug, a sealing element,a right end soft sealing plug and a sealing element, wherein an elastic fixing element is added on a leading-out terminal, and the inner portion of the recognizer cavity is sealed by high-strength potting glue. The digital axle recognizer has the advantages that the piezoelectric sensors are adopted, the number of tires is judged through the compressed number of the piezoelectric sensors, so thatsignals are accurate and stable, and the overall structure is simplified, and the size is reduced.

Description

technical field [0001] The invention relates to a digital axle identifier. Background technique [0002] Axle identifier, also known as vehicle type identifier, is an important part of the weight toll system, mainly used to detect the number of axles passing through the vehicle and the number of tires per axle, usually composed of piezoelectric sensors, when the vehicle passes, it will The piezoelectric sensor signal is converted into a tire number signal and so on. However, the existing wheel axle recognizer has a complex assembly structure and is very destructive to the road surface when the equipment is installed, which brings inconvenience to use. [0003] In order to solve the above existing problems, people have been seeking an ideal technical solution. Contents of the invention [0004] The purpose of the present invention is to provide a digital axle identifier to address the deficiencies of the prior art. [0005] In order to achieve the above object, the techn...
