Description

Technical Field

[0001] The invention relates to the technical field of fog detection instruments, and in particular to an intelligent control method, equipment and storage medium for a fog detector lens protection window. Background Art

[0002] Monitoring and early warning of fog on highways are of great significance to protecting people's driving safety. The visibility data provided by the atmospheric visibility measuring instrument provides a scientific and reliable basis for us to issue early warnings in a timely manner. However, the most important factor affecting atmospheric visibility is fog. Therefore, instruments specifically used to detect fog concentration are particularly important for daily transportation. Since fog detectors usually work outdoors, affected by environmental conditions such as wind, rain, and dust, the measurement accuracy of the instrument lens will be seriously reduced after being contaminated. Effective protection of the lens can maintain the stability of visibility measurement accuracy. In order to solve similar problems, a large number of patents have been disclosed in the field of atmospheric visibility detectors, such as the utility model patent "Optical Antenna Protection Window Glass of Atmospheric Visibility Instrument" (patent number: CN201503388U) discloses a method for preventing the protection window glass from being affected by water vapor. This method ensures that water vapor does not condense on the protection window glass through a heating device, but it cannot solve the problem of dust in the air depositing on the protection window glass, causing abnormal attenuation of light and affecting measurement accuracy. For example, the invention patent "A visual detection method and device for window mirror pollution of a transmission-type sight range visibility meter" (patent number: CN201610245605) discloses a method based on optical measurement. This method controls the opening and closing of the imaging window, converts the grayscale values ​​of the collected clean window mirror image and the actual window mirror image into optical intensity, calculates the extinction coefficient and compares them. It can obtain a closer to the real result for the extinction caused by non-uniformly distributed pollution, improve the accuracy of visibility measurement and the identification of pollutants, but it cannot protect the lens.

[0039] It should be further explained that, in the specific implementation process, the detection result is compared with the set threshold value, and the motor working mode is controlled by the controller, thereby controlling the probe sampling time and the switching time of the protective window.

[0040] Based on the same inventive concept, the present invention also provides a computer device, which includes: one or more processors, and a memory for storing one or more computer programs; the program includes program instructions, and the processor is used to execute the program instructions stored in the memory. The processor may be a central processing unit (CPU), or other general-purpose processors, digital signal processors (DSP), application-specific integrated circuits (ASIC), field-programmable gate arrays (FPGA) or other programmable logic devices, discrete gates or transistor logic devices, discrete hardware components, etc. It is the computing core and control core of the terminal, which is used to implement one or more instructions, specifically for loading and executing one or more instructions in a computer storage medium to implement the above method.

[0041] It needs to be further explained that, based on the same inventive concept, the present invention also provides a computer storage medium, on which a computer program is stored, and the computer program is executed by a processor to execute the above method.

By comparing the ambient temperature T, the ambient humidity H, the particle concentration N and the temperature threshold T0, the humidity threshold H0, and the particle concentration threshold N0, the corresponding working mode is selected. The control circuit board 6 is also connected to the probe 5.
