Intelligent control system and unloading control method for heat preservation semi-trailer transport vehicle

Abstract

The invention discloses an intelligent control system and an unloading control method for a heat preservation semi-trailer transport vehicle. The intelligent control system comprises a remote controller, a receiver, a detection unit and a plurality of control valves. The remote controller, the detection unit and the plurality of control valves are respectively connected with the receiver; the remote controller is used for sending an instruction through a wireless communication signal, and the receiver is used for receiving the instruction through the wireless communication signal; the detection unit comprises a driving distance detection unit and a belt conveying distance detection unit which are electrically connected with the receiver; each control valve comprises a rear cover door ascending electromagnetic valve, a rear cover door descending electromagnetic valve, a stock bin cover opening electromagnetic valve, a stock bin cover closing electromagnetic valve and a material conveying belt motor speed regulating proportional valve which are electrically connected with the receiver. According to the invention, the unloading speed is automatically adjusted to ensure that the height of the material level in an aggregate bin of a paver is not changed, the continuous material conveying of a transport vehicle and the continuous paving of the paver are realized, and the pavement paving flatness of the paver is improved.

Description

technical field [0001] The invention relates to an intelligent control system and a material unloading control method of an insulated semi-trailer transport vehicle, belonging to the technical field of engineering machinery. Background technique [0002] Insulated semi-trailer transport vehicles will gradually replace the first four dump trucks and the rear eight dump trucks for the transportation of asphalt mixture due to their advantages of heat preservation, large single-transportation volume, and safe unloading. [0003] At present, the insulated semi-trailer transport vehicles mostly use the belt conveying method to transport the asphalt mixture in the silo to the collecting hopper of the paver. During the construction process, the push rollers of the paver cling to the tires of the insulated semi-trailer truck to push the truck forward. When unloading, the operator of the paver observes the material level in the collecting hopper of the paver with the naked eye. When ...

AI Technical Summary

Problems solved by technology

However, when the paver is working at night, due to factors such as dark lights and smoke from the asphalt mixture, the sight of the paver operator will be affected, and the rear-view camera cannot clearly capture the material level in the paver collecting hopper. The operator of the paver and the driver of the transport vehicle cannot correctly judge the material level, resulting in insufficient material supply to the paver, which seriously affects the construction quality
