摘要
介绍了以CF卡为存储介质的长时间无人值守多路温度采集系统。系统采用单片机控制40路数字温度传感器DS18B20按采样间隔进行测量,将采集得到的数据按Excel文件格式记录,方便后续分析处理,实现了低能耗的电池供电模式。文章对硬件电路部分以及软件部分做了较详细的叙述,介绍了存储数据的文件系统。通过实践证明,该多路温度采集系统可以实现大范围分层次多点的温度数据测量。
A multi-channel digital temperature measurement without monitoring based on CF card is introduced. The temperature sensor is used as a detector in answer to the command of the singlechip, and then the data collected will be recorded in the form of Excel, which realizes the model of low consumption of battery. Both hardware design and software design are introduced in the essay in details, including system of recording data. From experience, this system can detect the temperature in a large spatial range.
