摘要

以Pt100等RTD传感器为前端采集元件，以STC12C5A60S2微处理器为核心控制器，在现场模块中建立温度采集、LED显示和nRF24L01变送器。然后通过USB连接到笔记本电脑上，通过短距离无线单元实现数据处理和存储。在现场试验和数据分析过程中，采用最小均方算法对采集数据进行处理。结果表明，当铂电阻电路放大倍率为35倍时，温度采集值呈现最佳的线性关系和较小的滞后。

Application of RTD Sensor in the Real Time Measurement and Wireless Transmission

The RTD sensors (such as Pt100) were taken as front end acquiring component and STC12C5A60S2 micro-processor was used as the core controller to establish the temperature acquisition, LED display and nRF24L01 transmitter in the field module. Then the data processing and storage was realized by the short distance wireless unit through the USB connection to the laptop. In the process of field test and data analysis, the least mean square algorithm was applied to process acquired data. The result shows that the values of temperature acquisition exhibit an optimal linearity and a smaller hysteresis when amplification ratio of the platinum resistor circuit was chosen 35 times.
