Visibility detector

Abstract

The invention discloses a visibility detector in the technical field of visibility detection, an infrared spectrum sensor is fixedly arranged at the center of the bottom of an inner cavity of a shell, and a first laser, a second laser and a third laser are sequentially, uniformly and fixedly assembled in the circumferential direction of the inner wall of the shell anticlockwise; a laser field is formed among the first laser device, the second laser device and the third laser device, a scattering state aerosol layer is arranged in the laser field, a storage battery is fixedly arranged at the bottom of an inner cavity of the electric control box, a control box is electrically connected to the left side of the top of the storage battery, and an information collector is electrically connected to the control box. The right side of the top of the storage battery is electrically connected with a power supply controller, so that the measurement result is more reliable, the sensitivity and the resolution of the system are improved, the detection stability can be improved in unit time, the defect of poor stability of traditional forward and backward scattering single-point transmitting and receiving is overcome, and the detection sensitivity and the resolution are greatly improved.

Description

technical field [0001] The invention relates to the technical field of visibility detection, belongs to the scope of atmospheric meteorological automatic detection devices, and is particularly suitable for a monitoring instrument for fog (visibility) monitoring of traffic roads and expressway road-type environments urgently needed in the field of intelligent transportation, specifically a visibility Detector. Background technique [0002] Fog is one of the extreme weather forms. The suddenness, regionality, mobility and other characteristics of cloud fog have brought great harm to traffic safety. At present, there is no good way to monitor and prevent it. When fog occurs, the visibility will suddenly decrease, which will have a serious impact on traffic and cause delays in airport flights; railways and highways are likely to cause major accidents and seriously threaten the safety of human life and property. At present, many countries in the world have given high priority to...

Problems solved by technology

When fog occurs, the visibility will suddenly decrease, which will have a serious impact on traffic and cause delays in airport flights; railways and highways are likely to cause major accidents and seriously threaten the safety of human life and property. At present, many countries in the world have given high priority to the detection of fog s concern

[0003] At present, the technology of visibility monitoring equipment in my country is backward, the market is monopolized by foreign products, and the price is expensive, which makes it impossible to implement real-time monitoring of atmospheric visibility on highways and shipping channels in my country.

However, in my country, the environmental visibility and cloud monitoring of highways are almost blank, so it is impossible to realize the real-time monitoring and forecasting of highway local and regional visibility and cloud fog. Therefore, we propose a visibility detector
