Ceramic pressure alarm for freeway automobile overweight

Abstract

The invention discloses a ceramic pressure alarm for freeway automobile overweight, comprising a piezoelectric ceramic circuit, a rectification and storage circuit, a power amplification circuit and a measurement and indication circuit, wherein the rectification and storage circuit rectifies and stores a voltage signal generated by the piezoelectric ceramic circuit; the power amplification circuit is connected with the rectification and storage circuit; the measurement and indication circuit measures and indicates the output signal of the power amplification circuit; the piezoelectric ceramic circuit is connected with the rectification and storage circuit; the power amplification circuit is connected with the measurement and indication circuit; and the piezoelectric ceramic circuit is composed of piezoelectric ceramics PZT. The ceramic pressure alarm has the advantages of simple structure, reasonable design, low cost and good use effect, is convenient in installation and intuitional in display, is simple and feasible, can instantaneously display automobile weight, provides references for management personnel, and effectively solves the problem of accurately measuring automobile load so as to guarantee driving safety to a great degree.

Description

technical field [0001] The invention relates to a pressure alarm, in particular to an overweight ceramic pressure alarm for highway vehicles. Background technique [0002] At present, vicious casualty accidents caused by overweight vehicles on highways occur frequently. The special nature of highways makes it difficult for supervisory departments to accurately grasp the load status of vehicles from time to time. Grasp, but often when a traffic accident has taken place and the cause is traced, it is found that it is caused by the overweight of the car. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an automobile overweight ceramic pressure alarm, which has a simple circuit, reasonable design, low cost, convenient operation and installation, and good use effect. The weight is displayed in an instant, providing reference for management personnel, and effectively solving the problem of accurate measurement of vehic...
