Design of Computer Control System of Mobile Asphalt Concrete Mixer

Abstract:

In order to achieve the application requirements of a mobile asphalt concrete mixer, a distributed computer control system of the mixer is developed with an industrial control computer and a S7-200 PLC. Through analyzing the operation principle of mixer, main functions and specifications of the system are proposed. In this paper, the hardware constitution and the software design method of the system are introduced in detail, and the working process of the asphalt concrete mixer can be controlled automatically and intelligently in real time. Moreover, the functions of batching control, process monitoring and data management has been realized. Test results show that the asphalt concrete mixer works stably and reliability.
