Design Of Control System For Synchronous Lithotripsy Sealing Car Based On Machine Vision

The surface of the road and deck needs to be tested before the synchronous spilt of the asphalt and crushed stone.According to the surface evenness,the width of the pavement is controlled by the spray amount of the asphalt and the crushed stone.In order to improve the quality of highway protection and maintenance,it is urgent to improve and apply the new technology in order to improve the quality of the maintenance and maintenance of the highway.Therefore,we carried out machine vision based synchronous gravel seal vehicle control system.On the basis of analyzing and studying the synchronous rubble sealing vehicle at home and abroad,the optimization design of synchronous gravel seal car based on machine vision is put forward.The scheme combines the machine visual function sensing technology with the electric and hydraulic control of the sealing car.According to the conditions of the road and the environment,the speed,the speed of the pump,the asphalt or the stone spray are controlled,and the spraying precision,the synchronism and the wrapping strength are improved.According to the technical index of synchronous lithotripsy sealing car based on machine vision,the research and design of the hardware system,software system and test experiment of the control system of the sealing car are carried out.The system works in order under the control of the total control board: the industrial camera identifies the surface of the pavement and the collection of the image information,and transmits it to the industrial control machine through Ethernet,and then transfers the results to the system control board through RS-485 communication,and the total control board can adjust the asphalt and stone according to the detected temperature and speed.The amount of spray.In this paper,a speed measuring system based on machine vision is designed.Through the establishment of speed detection model,camera model,and the calibration and image processing,the speed of the synchronous lithotripsy seal car is calculated by the light flow method.The synchronous sealing technology realizes the synchronous spreading of asphalt and stone according to the speed and temperature,and ensures the maximum surface contact between the two.It has achieved the basic requirement of forming the asphalt stone wear layer through the rolling or roller compacted by the daily vehicles.The cost is low,the energy consumption is small,the waterproof and skidding effect is good,and it has high resistance.Grinding and durability.In particular,the introduction of machine vision makes the development of the vehicle new breakthrough for the homemade of similar equipment.It is also a specific application of machine vision in road recognition.It provides valuable experience for machine vision in the field of industrial control intelligent control.
