摘要
针对在工农业生产中温度测点距离远、监测环境范围大、布线不便等特殊环境,采用集成芯片PT2262/PT2272构建了无线方式传输温度数据,温度由DS18B20温度传感器采集,设计了以AT89C51单片机为核心的温度数据采集系统的硬件电路以及软件系统,实验测试表明,系统采集的温度绝对误差小于0.3℃,无障碍传输距离达4.2m。集成芯片的采用,使得系统微型化,且性能稳定、精度高、使用简洁。
In the industrial and agricultural production in the temperature measuring point distance,environment monitoring range,wiring inconvenience and other special environment,to construct the transmission temperature data wirelessly using integrated chip PT2262/PT2272,temperature acquisition by DS18B20 temperature sensor,the design of hardware circuits of temperature data acquisition system based on AT89S51 microcontroller as the core of the system and the software,test results show temperature acquisition：System of collecting temperature absolute error is less than 0.3℃,the wireless transmission distance up to 4.2 meters.By integrated chip,make the system miniaturization,and stable performance,high precision,simple to use.
