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...
Embodiment 3
[0079] An embodiment of the present invention provides a storage medium containing computer-executable instructions, and the computer-executable instructions are used to execute the methods described in the foregoing embodiments when executed by a computer processor.
[0080] The computer-readable storage medium of the present invention detects the real-time visibility of each site and analyzes the size of the site's visibility information, and analyzes the change trend of the adjacent site's visibility information and the change of the site, through data collection and analysis of the base station 4 Collect the visibility data measured by all stations to obtain the visibility change curve of the entire monitored road, and combine the individual visibility changes of each station with the correlation of the visibility changes of adjacent stations according to the curve change trajectory of the past, such as every minute and every ten minutes in the past Judging the occurrence r...
