Transmission method visibility detection device and method applied in field of transportation

Abstract

The invention relates to a transmission method visibility detection device applied in the field of transportation. The transmission method visibility detection device consists of single bodies which can be configured according to requirements and can operate independently and further comprises a pair of detection devices, wherein one detection device transmits detection light beams; the other detection device receives and analyzes attenuation generated by the detection light beams from the transmitting end to the receiving end and then acquires a visibility numerical value accordingly; each configured visibility detection device is provided with interfaces and protocols merged or jointed with data actually measured by other similar visibility detection devices; and a long-distance and high-regional-resolution visibility numerical value representation belt consists of a plurality of detection regions on the basis of the interfaces and protocols which are jointed mutually. In a transmission method visibility detection method applied in the field of transportation by using the device, the visibility numerical value is analyzed by detecting the change of the received light beams; a receiver converts the variable of the detected light beams into the variable of electrical parameters; and the current visibility numerical value is inquired by inquiring the numerical value relationship stored in a visibility control database.

Description

technical field [0001] The present invention relates to a transmission method visibility detection method and device applied in the field of traffic, in particular to a high-regional resolution visibility detection method which is mainly used in the field of road traffic and inland waterway traffic and can configure the visibility value. device. [0002] Background technique [0003] The change in visibility is the light attenuation phenomenon caused by the scattering and absorption of light by atmospheric suspended matter. The World Meteorological Organization has a clear definition of visibility, that is, the Meteorological Optical Line of Sight (MOR), which expresses the attenuation of a specific light source to a predetermined value by the atmospheric environment. The path distance traveled is the visibility distance. [0004] The existing international visibility detection detection methods are mainly to detect the visibility state of a monitoring point, and specu...
