Design Of Control System Based On Single-chip Wet Spreader

In winter, especially in the cold area, highway icing has great hidden danger to the safety of artificial icing time consuming and low efficiency, obviously does not meet the demand of the social development of modern high speed. With the development of science and technology, spreader has gradually replaced the artificial ice melting operation. However the spreader in technology introduction, self development ability is weak, resulting in technology introduction spreader expensive, application and maintenance cost is high, self-developed spreader snowmelt in low efficiency, spreading precision, resulting in waste of snowmelt agent, irreversible damage to the highway, the environment will be. Based on the efficiency of spreading machine core or control system. Therefore, the design of a set of effective snowmelt deicing, damage degree, high degree of automation of multifunctional snow spreader is imperative. This paper is in reference to the Qinghai Jieshen equipment manufacturing group company from South Korea to introduce RSW-800 wet type spreading machine based on through to MCU as the core controller developed control system, closed loop control, through the PID algorithm to achieve accurate on spreading density, spreading width, deicing salt, and humidity control, improve the degree of automation, reduce the maintenance cost of application is built. In addition, based on the Qinghai Jieshen equipment manufacturing group company from South Korea imported RSW-800 wet spreader separation of the man-machine interface, easy to operate the disadvantages of independent development based on touch screen visualization interface system, and PC through the serial communication connection, so as to integrate the function of the operation interface, and easy to get started with the purpose of.This paper mainly introduces the wet dusting machine working process, learn from the Qinghai Jieshen equipment manufacturing group company from South Korea introduced RSW-800 wet spreader and expounds the existing problems. On this basis, independent design and development a single-chip automatic control system and interface system based on. The introduction of single-chip microcomputer and peripheral hardware circuit selection, design, software programming, the simulation results under the experimental conditions.
