Problems solved by technology

[0002] With the development of science and technology, more and more detection instruments have been applied to people's lives. Road and traffic detection equipment has also been widely used beside vehicles and roads. Most vehicles now use cameras to collect road traffic information. , but the camera can only take images, and cannot judge and remind the roads of rain, snow, icing, etc. Various states still need people to judge, and the camera function will be greatly reduced when it is dark

Abstract

The invention discloses a road surface state instrument control circuit, and the circuit comprises a control acquisition system and an infrared luminescence acquisition system; the infrared luminescence acquisition system can emit infrared light and acquire infrared signals, and the control acquisition system can judge the road surface state according to the infrared signals and send road surface information and environment information to a user. The control acquisition system and the infrared luminescence acquisition system are connected through an interface module, and the control acquisition system comprises a main control module, and a power supply module, a communication module, a Bluetooth module, an environment detection module, a data conversion module, a storage module and an indication module which are connected with the main control module; and the infrared luminescence acquisition system comprises an infrared LED driving module and an infrared signal receiving module. The road surface state can be judged by integrating the temperature and humidity of the environment where the instrument is located, the road surface temperature and the dew point according to different LED infrared signals of the road surface in various states, and the road surface state detection device has good market application value.

Description

technical field [0001] The invention relates to the field of detection instruments, in particular to a road surface state instrument control circuit. Background technique [0002] With the development of science and technology, more and more detection instruments have been applied to people's lives. Road and traffic detection equipment has also been widely used beside vehicles and roads. Most vehicles now use cameras to collect road traffic information. , but the camera can only take images, and cannot judge and remind the roads of rain, snow, icing, etc. Various states still need people to judge, and the camera function will be greatly reduced when it is dark. Contents of the invention [0003] The present invention aims at the deficiencies of the existing road surface detection equipment, and provides a road surface state instrument control which can judge the state of the road surface according to the difference of LED infrared signals in various states of the road surf...
