Problems solved by technology

[0006] The transmissive visibility measuring instrument does not make uniform assumptions about the atmosphere, but directly measures the transmittance and extinction coefficient of the atmosphere. The measurement accuracy of the visibility is high, but the detection range and accuracy depend on the length of the baseline, and the installation is complicated. Due to the influence of the transmittance error The measurement error is relatively large when the visibility is high, and the error caused by lens pollution is relatively large
[0007] The front-scattering visibility measuring instrument is compact in structure, small in size, easy to install and maintain, and has a wide measurement range. The pollu

Embodiment 1

[0036] Such as figure 1 As shown, the visibility detection system of the present invention includes: several visibility detection stations 5, the visibility detection stations 5 are used to detect the atmospheric visibility information of the location; data collection and analysis base station 4, the data collection and analysis base station 4 The visibility detection station 5 is connected by wired or wireless means; the data acquisition and analysis base station 4 receives the atmospheric visibility information measured by the visibility detection station 5 in real time, and fits the visibility information of each station.

[0037] The visibility detection system of the present invention, by detecting the real-time visibility of each site and analyzing the size of the site visibility information, and analyzing the change trend of the adjacent site visibility information and the change of the site, through data collection and analysis Base station 4 collects all Based on the ...

Embodiment 2

[0052] Such as Figure 5 As shown, the present embodiment also provides a method for early warning of cloud fog on expressways, including the following steps:

[0053] S101: By installing a set of miniature visibility detection detectors 3 every 100 meters on the monitored road section, and saving the actual latitude and longitude and altitude information of the site to the data processing unit 304.

[0054] By installing wireless micro-backscatter visibility detection detectors 3 continuously in a large area, the continuity and accuracy of the measured data can be guaranteed, making the calculation of the direction of highway fog more scientific and accurate. Each wireless micro-backscatter visibility The detection detectors all save the longitude, latitude, altitude and high speed of the site to provide a scientific basis for the algorithm and prediction of the fog's moving direction.

[0055] S102: Measure the visibility information of the installation site through the wir...

Abstract

The invention provides a visibility detection system and method and a computer readable storage medium. The system comprises a plurality of visibility detection stations which are used for detecting the atmospheric visibility information of a located position; a data acquisition and analysis base station is connected with the visibility detection stations in a wired or wireless mode; and the dataacquisition and analysis base station receives the atmospheric visibility information measured by the visibility detection stations in real time, and fits the visibility information of each station. The visibility detection system detects the real-time visibility of each station through the visibility detection equipment to judge the occurrence range and the moving direction of agglomerate fog, calculates the visibility danger level and the moving direction of the agglomerate fog according to the calculated data, sends the visibility danger level and the moving direction of the agglomerate fogto the expressway monitoring center and gives an early warning to inform a driver.

Description

technical field [0001] The invention relates to the fields of optical measurement and intelligent transportation, and more specifically, the invention relates to a visibility detection system, method and computer-readable storage medium. Background technique [0002] Changes in weather conditions, especially extreme weather conditions, have brought huge risks to road vehicles, which not only seriously affect transportation, but also cause serious losses to national property and people's lives and properties. Therefore, the monitoring of road weather conditions is an important basis for the scientific operation of highways. Visibility is an important meteorological observation element. Due to the influence of the microclimate environment in local areas, the small-scale dense fog formed is called group fog, which is also an important factor affecting visibility. Due to its characteristics of strong suddenness, obvious locality, small size, and high concentration, the driver's ...
