摘　　要：数据中心一些关键部位的温度监控系统存在温度设置不合理的问题。为此,提出一种基于nRF24L01的无线多点温度高频实时采集设计方案,给出具体的系统硬件电路和软件实现。该系统的硬件电路中各温度传感器与单片机的I/O端口一一对应,利用I/O端口标识温度传感器,提高采集频率。软件实现部分通过对数据进行压缩处理,减少发送数据量,提高无线传输效率、降低功耗,从而实现温度数据的传输、显示并存档等功能。实验结果表明,该系统能以1 Hz的采集频率同时对多个温度点进行实时采集,采集温度的误差小于0.5℃,丢包率小于5%,并提高了无线通信的传输效率。This paper analyzes current status and challenges of the temperature monitoring system for the critical components of data center.To address the challenges,the design of real-time wireless high frequency multi-point temperature sampling system based on nRF24L01 is presented,and hardware circuit as well as software implementation of the system is described.Temperature sensors of the hardware circuit are in accord with the I/O ports of the micro control unit,and the I/O ports are also used to identify the temperature sensors to improve the efficiency of wireless transmission;At the software implementation,in order to reduce the data transmitted as well as improve efficiency of the wireless transmission and reduce power consumption,the data is compressed,thereby the transmission,display and storage of the temperature data are implemented.Measured results show that the system can sample the temperature for many points with the frequency of 1 Hz at the same time.The error is less than 0.5 ℃,the rate of package loss is less than 5%,and improves the transmission efficiency of communication.
