摘要
本文设计了一种智能风扇控制系统,该系统以STC89C52单片机为核心,由DS18B20温度传感器、热释电传感器、舵机、LCD1602液晶显示屏、按钮等元器件组成。整个系统先由温度传感器采集外界温度并传送至单片机进行智能显示工作。热释电传感器会检测周围人的方位信号,并将此信号发送到单片机,单片机通过对该信号的判定识别,再向舵机发出控制信号,实现智能转向的功能。在整个工作过程中,单片机都会对整个系统的模式进行判断,并进行相应的控制。
The paper designs a novel intelligent fan＇s control system which is based on the MCU as the core,and is composed of heat temperature sensor DS18B20,heat release electric sensor,actuator,LCD1602 LCD display,buttons and other components. Outside temperature is measured by the temperature sensor and is sent to the SMC to display intelligently. Then the position signaling of people is measured and sent to the micro-controller. After that,the signal is processed by the micro-controller and the micro-controller sends out controlling signals,so as to realize the automatic steering function. During the whole working process,the micro-controller judges modes of the whole system,and controls the correspondingly.
