Abstract

The invention relates to an instant speed measuring instrument and belongs to the vehicle speed measurement method field. In the use process of the instant speed measuring instrument of the invention, firstly, the instant speed measuring instrument is started and operate normally, and aligns with a vehicle running ahead so as to measure the speed of the vehicle; electromagnetic waves reflected by an object are transmitted to an infrared imaging chamber; the infrared imaging chamber transmits time and the distance of infrared wavelength which are recorded by driving simulation to a micro processor, so that the time and the distance of infrared wavelength can be processed; and finally, the time and the distance of infrared wavelength can be converted into digital signals which are displayed by a display screen. The instant speed measuring instrument of the invention has the advantages of fast and accurate speed measurement, simple structure, low cost, convenient installation, use and maintenance. The instant speed measuring instrument of the invention is not affected by natural environment and weather conditions, and can realize all-weather speed measurement.

Description

technical field [0001] The invention relates to an instant speed measuring instrument, which belongs to the field of vehicle speed measuring methods. Background technique [0002] Infrared imaging technology is a promising high-tech. Electromagnetic waves longer than 0.78 microns are located outside the red of the visible light spectrum. They are called infrared rays and infrared radiation. Part of it is called near-infrared, and the part with a wavelength of 2.0-1000 microns is called thermal infrared. In nature, all objects can radiate infrared rays. Therefore, using the detector to measure the infrared difference between the target itself and the background can obtain infrared images formed by different thermal infrared rays, and even use the "red shift" and "blue shift" of infrared rays. Measurements while driving are of great significance. [0003] With the continuous development of traffic safety in our country, it is very important to accurately measure the speed of...
