A mine locomotive collision avoidance method and device based on segmented hybrid ranging

Abstract

The invention discloses a mine locomotive anticollision method and device based on segmented hybrid distance measurement. According to the method, radio signals are used as synchronous communication signals in the whole distance measurement process, different propagation characteristics of a radio, sound waves and ultrasonic waves are utilized for performing remote distance measurement, middle-distance distance measurement and close-distance distance measurement on mine locomotives, the radio response of the radio is utilized for performing remote distance measurement, energy intensity detection of the sound waves is started and utilized for performing middle-distance and remote rough distance measurement after the radio communication response is completed by the two locomotives, finally, transmission time of the ultrasonic waves is restarted and utilized for close-distance distance measurement, and corresponding motions are executed according to the distance measurement results of all segments; the characteristic that the performance of radio transmission and performance of the sound wave transmission are hardly affected by light rays, dust, smoke and air humidity in the environment under a mine is utilized; when an error exists in sound wave detection, the ultrasonic waves can be utilized for precise measurement. The method is high in environmental adaptability, large in detection range, high in distance measurement precision and high in reliability.

Description

technical field [0001] The invention relates to a mine locomotive anti-collision method and device, in particular to a mine locomotive anti-collision method and device based on segmented hybrid ranging, and belongs to the technical field of mine locomotive anti-collision methods and devices. Background technique [0002] At present, most mine locomotives are not equipped with anti-collision devices, but rely on the driver's naked eye observation to determine whether there is a car ahead, and take corresponding measures according to the results of the naked eye observation. However, when the dispatcher misoperates or the driver is fatigued, a collision may occur due to failure to detect the locomotive in front in time, thereby causing a safety accident. [0003] With the rapid development of science and technology, in order to reduce the collision of mine locomotives, people have developed a variety of methods and devices for collision avoidance warning, commonly used methods...

AI Technical Summary

Problems solved by technology

[0004] The anti-collision warning method and device based on computer vision or image, laser or infrared ranging is to use laser or infrared ranging device to detect the situation around the mine locomotive; Harsh, high temperature, humidity, and dusty, the anti-collision device using the optical principle is easily affected by factors such as underground lighting conditions, dust, and air humidity. For example, dust will be adsorbed on the optical lens, resulting in system failure or large measurement errors. False reporting or missing reporting will occur, with low detection accuracy and low reliability;

[0005] Although the anti-collision early warning method based on the underground signal collection and closing system and RFID precise positioning will not be affected by underground lighting conditions, dust, air humidity and other factors to produce false or missed reports, the detection accuracy is high, but when it is implemented, it needs Layout of a large number of line sensors such as axle counters in the information collection and closing system and card readers in the RFID positioning system is costly, and it will also cause difficulties in system installation and maintenance, affecting its own practicability and application effect, which is not conducive to promotional use

[0006] In addition, the different devices involved in the above two methods also have the same problems as the method
