Description

technical field [0001] The invention relates to an underground roadway vehicle monitoring device, which belongs to the field of electronic technology. Background technique [0002] At present, vehicle speed measurement mainly includes radar speed measurement, laser speed measurement, video speed measurement, ground induction coil speed measurement and so on. Radar speed measurement uses the Doppler effect to calculate the target speed through the Doppler frequency shift. Laser speed measurement adopts the principle of laser distance measurement, that is, conducts laser distance measurement on the measured object twice with a specific time interval, and obtains the moving distance of the measured object within this period, so as to obtain the moving speed of the measured object. Video speed measurement is to use the two-dimensional position of the vehicle in the vehicle image and the corresponding parameters determined in advance to calculate the actual three-dimensional pos...

Problems solved by technology

[0003] However, in special environments such as vehicle speed measurement in mine tunnels, due to the characteristics of narrow tunnels, low illumination, large construction volume and large amount of dust, it is impossible to use the above speed measurement equipment for speed measurement

And because the underground environment is special, the uphill and downhill slopes and slopes and road conditions are different, it is impossible to use the traditional speed limit mode to limit the speed. Therefore, it is necessary to improve the existing technology
