基于STC单片机的智能风扇控制系统
首发时间:2022-01-25
摘要:本文所设计的智能语音风扇控制系统采用两个STC89C52单片机分别作为主机和从机的核心,利用主从一体的HC-05蓝牙模块实现两个单片机之间的短距离无线数据传输,实现了对风扇的智能控制和手动控制这两种工作模式。在智能控制模式下,通过NRK11语音识别芯片接收语音信号,利用DS18B20数字温度传感器实时测量温度,对风速与语音信号、温度的关系进行建模,最终获得匹配的最佳风扇转速;在手动控制模式下,通过独立按键实现对风扇的换挡。同时,通过NRK11语音识别芯片接收语音信号,也可以实现对小灯亮灭的控制。实验测试表明,该系统具有较强的稳定性,可以广泛应用。

Intelligent fan control system based on STC MCU
Abstract:The intelligent voice fan control system designed in this paper uses two STC89C52 single chip microcomputer as the core of the host and the slave, and uses the master-slave HC-05 Bluetooth module to realize the short-distance wireless data transmission between the two single chip microcomputer, and realizes the intelligent control and manual control of the fan.In the intelligent control mode, the voice signal is received by NRK11 voice recognition chip, and the temperature is measured by DS18B20 digital temperature sensor in real time. The relationship between wind speed and voice signal and temperature is modeled, and the optimal fan speed is finally obtained.In manual control mode, the fan can be shifted by independent keys.At the same time, NRK11 speech recognition chip to receive voice signals, can also achieve the control of small light off.Experiments have shown that the system has strong stability and can be widely used.
