Research on Adaptive Control Strategy of Intelligent Spray System

By looking back the research status both at home and abroad, the overall plan of the target spray control system of self-propelled target sprayer is formulated. Based on the speed to dynamically adjust the sampling frequency by single chip microcomputer controller to realize three consecutive sampling methods for identifying targets and the algorithm of interference signal filtering, solenoid valve is used to control the spray opening and closing, combining with technology of target based on laser sensor. In this paper, main components of the hydraulic circuit are selected and STCI2CSA60S2 is set as the core to design the connection of single chip processor module, signal detection module, matrix key module, liquid crystal display module, alarm indicator module and serial interface communication module. Based on the C language, the handler and target discrimination algorithm is written, including the processing of the main program, the target sampling, detection, alarm indication and matrix button subroutine.
