An accurate obstacle avoidance linkage control system for the dust suction port of a track road cleaning vehicle

Abstract

The invention relates to a linkage control system, in particular to the linkage control system capable of allowing a dust suction inlet of a track street clearing vehicle to avoid obstacles accurately. The linkage control system is characterized in that a vehicle body is connected with a support, a driven wheel is arranged on the support and connected with a driving wheel on a wheel through a chain, and a tensioning wheel is connected with the chain. A laser, a camera and an alternating current servo motor are fixed under the vehicle body, an industrial personal computer and a servo driver are fixed on the vehicle body, the industrial personal computer is connected with the displayer, the alternating current servo motor is connected with a lead screw connected with a nut seat connected with the dust suction inlet, and the driven wheel is connected with an encoder. A self-programmed program meeting requirements is embedded into the industrial personal computer. By means of the technical scheme, the linkage control system capable of allowing the dust suction inlet of the track street clearing vehicle to avoid obstacles accurately has the advantage of being convenient to install and debug, accurate and reliable in judgment and strong in practicability.

Description

technical field [0001] The invention relates to a control system, in particular to an accurate obstacle avoidance linkage control system for a dust suction port of a track road surface cleaning vehicle. Background technique: [0002] At present, the systems used for obstacle avoidance mainly include: laser radar imaging technology scans and displays information such as the three-dimensional image, distance and speed of the target by laser scanning, and performs target positioning and identification. The disadvantage lies in the high requirements for the laser and its scanning device, and poor imaging quality. , slow speed, complex structure, bulky size and high cost. Ultrasonic ranging technology uses ultrasonic sensors as ranging sensors, which can be used for obstacle avoidance of indoor mobile robots, cars, etc. Influences such as changes in the incident angle with the target object, and the resolution is poor.
