Problems solved by technology

[0003] However, the existing asphalt transfer technology can only use the travel switch to judge the stop position of the material transfer device, and it is impossible to predict the travel position of the material transfer device in advance, and it is impossible to accurately control the operation of the transfer device. It also exists in similar application scenarios

Embodiment Construction

[0037] Such as figure 1 As shown, it is a schematic diagram of the principle of the material transfer control system provided by the embodiment of the present invention. There can be one finished product warehouse for the material, or multiple parallel ones, such as the No. 1 finished product warehouse and No. 2 finished product warehouse shown in the figure. The material transfer device of asphalt mixture is pulled by the traction equipment, and can run along the track from the discharge port of the mixing main engine to the material connection port of the finished product warehouse. For the material transfer device, the discharge port of the material processing device is the material transfer device The first interface for loading materials and the material receiving port of the finished product warehouse are the second interface for unloading materials from the material transfer device. The positions of the first interface and the second interface of each finished product wa...

Abstract

The invention relates to the automatic control technology and provides a system, a method and a device for controlling material transfer, which are used for realizing intelligently automatic control of material transfer. The system for controlling material transfer comprises a dragging device, a position detecting device and a control device. By the system, the method and the device for controlling material transfer, automatic control of a material transfer cart is realized, and running speed of the material transfer cart can be reduced in advance before the material transfer cart stops, so that the material transfer cart can stop quickly and accurately at the low-speed state. Safety potential hazards caused by sudden change of the speed is avoided by speed reduction of the material transfer cart, safety during material transferring is improved, and meanwhile, the material transfer cart can run at a higher speed before deceleration, and accordingly efficiency of material transfer is improved.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to an automatic material transfer control technology. Background technique [0002] Asphalt mixing equipment (referred to as asphalt plant) is one of the key equipment for asphalt pavement construction. The material is mixed at the specified temperature to form a uniform mixture. In the asphalt concrete mixing plant, the finished product is often sent to the finished product warehouse by the material transfer device for heat preservation and storage, and then sent to the construction site by the transport vehicle. With the improvement of the production capacity of the asphalt concrete mixing plant and the increasing scale of traffic construction, the Higher requirements are placed on the safety and efficiency of material transfer devices for finished product transportation. [0003] However, the existing asphalt transfer technology can only use the travel switch to judge the stop ...
