用于温室的多功能电机控制系统设计

IGreenhouse is an important component of modern agriculture in China. For the environment of greenhouse crop special growth, the different service of various need to be offered by the controlling motor. There are issues which are the characteristics of greenhouse operation, motor varieties, equipment upgrade difficulties, and resources waste .In this paper, with the single chip processor as the main control device and MOSFET as the main power switch device, the working principle、design and realization of the system are expounded from two aspects of hardware and software. The double machine communication is made of the single-chip microcomputer STC12C08AD and STC12C5A60S. The implementation of a variety of motor drive and control is made of the double machine communication、encoder speed、dc power supply、LCD display. This multi-function motor drive system can realize motor PI regulation speed, and has a function of under voltage、over voltage、over current protection. The greenhouse multifunction operation and controlling are achieved.
