Abstract

In rice planting technology, the planting depth of seedlings has high requirements for transplanters, which directly determines the survival rate and tillering effect of seedlings. Aiming at the problems of low automation degree and low working efficiency of rice transplanter, the rice transplanter is designed under WSN (Wireless Sensor Network) technology, and its electric control system is optimized and analysed. In this paper, in order to optimize the overall working performance of the electronic control mechanism system of adjustable width and narrow row high-speed rice transplanter, the discipline analysis of the electronic control mechanism system is carried out based on WSN (Wireless Sensor Network) technology. Combined with the working characteristics of electronic control mechanism and the influence index of design parameters, the multidisciplinary design optimization framework of electronic control mechanism is established, and the optimization objectives, design variables and constraints at system level and discipline level are determined, and the multidisciplinary design optimization mathematical model of electronic control mechanism is constructed. Finally, the optimization results are analysed. The results show that the optimized design variable value can significantly improve the overall working performance of the adjusting mechanism of the electronic control system.
