摘　　要：本系统旨在实现对加热炉中水的温度进行远程无线测控。采用红外温度传感器检测加热炉表面的热辐射能量并转换为电压信号,电压信号经调理电路处理后由无线单片机NRF9E5I进行A/D转换及发送预处理,再通过发送电路以一定频率进行无线发送,接收端的无线单片机NRF9E5II接收这一频率的信号进行处理,取出水的温度信息由液晶显示器显示水的温度。同时加热的时间信息也一并发送,当温度达到设定值时NRF9E5II再回发关闭信号关闭加热器。该测试系统测量精度高、信号稳定、传输距离长,实现了加热设备的远程无线测控。Aiming at wireless measurement and control of the water temperature in the heating stove. Infrared temperature sensor detects the surface radiation energy of the stove and converts it into voltage signal; the signal is disposed by regulating circuit, and then the A/D converting circuit and pre- disposal circuit of wireless NRFgE5,subsequently the signal is transmitted by wireless transmitting circuit within the NRFgE5 at certain frequency. Another wireless NRFgE5 at the receiving part receives this signal and extractives the temperature information and displays on LCD after disposed. At the same time, the heating rime is also being transmitted, when the temperature arrives at the set value, the shut signal is transmitted back and the stove is closed. This system has the character of high precision, stabilization and far- distance. Thus the remote water temperature is tested.
