摘要
以AT89S52单片机为核心,由温度传感器及放大模块,采集数据处理模块,键盘数码管模块,语音模块和LCD显示模块组成。其中利用性能良好的温度传感器来实现温度和电压的变换,经过高精度的OP放大器后再通过12位的采样,保证了采样的精度。最后又通过软件操作,实现报警温度预置,LCD、LED显示,语音播放等功能实现了人机互动。
The AT89S52 SCM is the core of the entire system, which is composed of the temperature sensor module, data collection module, data processing module, keyboard number tube module, voice module and LCD display module. The temperature sensor of good performance is used to transform temperature into electrical pres- sure. The accuracy of sampling is guaranteed by the OP magnifier of high precision and 12 bit sampling. Such interactive functions as warn temperature initialization, LCD or LED display and sound playing are realized.
