Infrared scanning vehicle separator having automatic heating function

Abstract

The invention relates to an infrared scanning vehicle separator having automatic heating function, is mainly composed of a pair of a transmitter and a receiver which are arranged at opposite positions and comprises a housing arranged inside a protective covering; the front end of the housing fixes an optic window of heating glass by a sealing bar; the transmitter or receiver consisting of same number of infrared transmitting tubes or receiving tubes is fixed in the middle of the housing; the invention is characterized in that the lower surface of the optic window of heating glass is tightly stuck to a temperature switch, a transmitter or receiver control circuit and drive circuit connected with the temperature switch are installed in the middle of the housing, and the transmitter is communicated with the receiver by synchronous communication lines. The invention has the beneficial effects that the control circuit and drive circuit can be automatically started to heat the vehicle separator heating glasses under bad weather (rain, snow and fog) and the heating of heating glass is controlled by software in pulse control manner, thereby avoiding damages caused by long-term electrifying of heating glass. The window of heating glass on the protective covering is removed, thereby reducing attenuation for infrared transmitted lights.

Description

technical field [0001] The invention belongs to the equipment for separating passing vehicles used in the road toll collection system by weight, and in particular relates to an infrared scanning vehicle with automatic heating function working in the field environment and in bad weather (rain, snow, fog) Splitter. Background technique [0002] The infrared scanning vehicle separator is a device used in the highway toll collection system to separate the passing vehicles. At present, the vehicle separators on the market are installed in the protective cover, and the protective cover is equipped with heating glass, temperature switch, humidity switch and other components, and the heating function is realized through these components. In the case of bad weather (rain, snow, fog), avoid the window of the vehicle separator from being covered by rain, snow, and fog, which will affect the normal use. The structure of the current product is that there are two layers of optical windo...

AI Technical Summary

Problems solved by technology

Each layer of window will attenuate the infrared emission light, and the attenuation will be more serious in bad weather conditions

At present, the product controls the heating of the heating glass through a temperature switch and a humidity switch. The two switches are connected in parallel. When any switch is turned on, the heating glass will be heated, which will easily cause the heating glass to be in a heating state for a long time (especially in winter) , which accelerates the damage of the heated glass
