Motor vehicle radar speed measurement meter field simulation method and detection device

Abstract

The invention provides a motor vehicle radar speed measurement meter field detection device and a simulation method which are used for on-site detection of a detected motor vehicle radar speed measurement meter. The device comprises a movement target simulation device, a microwave frequency counter, a microwave power meter, an industrial control machine, a closed-loop control pan-tilt and a range finder function unit. The movement target simulation device receives microwave signals of the detected motor vehicle radar speed measurement meter, doppler signals are superimposed, then modulation microwave signals are emitted to the detected motor vehicle radar speed measurement meter, the microwave frequency counter and the microwave power meter receive microwave emission frequency and emission power of the microwave signals respectively, the industrial control machine is connected with the microwave frequency counter / the microwave power meter, the ranging finder and the closed-loop control pan-tilt so as to receive and process data, control operation of function units and coordinate the detection device to automatically finish the whole detection process, the problem that authenticity and repeatability in the motor vehicle radar speed measurement meter on-site detection process are difficult to consider is solved, and a scientific, safe and efficient on-site simulation scheme is provided for detection.

Description

technical field [0001] The invention relates to an on-site detection device for a motor vehicle radar speedometer, and also provides a field simulation method for a motor vehicle radar speedometer. Background technique [0002] According to the World Health Organization, approximately 1.24 million people die each year as a result of road traffic collisions, and an additional 20 to 50 million suffer non-fatal injuries, many of whom are disabled. Estimates made in 2000 put the economic cost of road traffic crashes at approximately US$ 518 billion. And China is one of the countries with the largest number of traffic accident deaths in the world. Since the end of the 1980s, the number of annual traffic accident deaths in China has exceeded 50,000 for the first time, and China (excluding Hong Kong, Macao and Taiwan) has hundreds of thousands of traffic accidents every year. Since the beginning of the year, the number of deaths due to traffic accidents has ranked first in the wor...

Problems solved by technology

[0011] The purpose of the present invention is to provide a kind of on-the-spot simulation method and detection device of a motor vehicle radar speedometer, to solve the existing simulation method and detection device that do not fully consider the inconsistency between the microwave emission frequency and the nominal value of the motor vehicle radar speedometer and the width and width of the main lobe of the radar. The different installation angles of the radar can neither fully reflect the speed measurement characteristics of the motor vehicle radar speedometer, nor can it fully guarantee the accuracy of the motor vehicle radar speedometer after it is installed on the speed measurement site, and there are uncertainties with the existing on-site detection methods Large size, poor safety, low efficiency, inability to perform full-scale detection and repeatability measurement, etc.
