【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。
[Abstract]:The temperature monitoring system in some key parts of the data center has the problem of unreasonable temperature setting. Therefore, a design scheme of wireless multi-point temperature real-time acquisition based on nRF24L01 is presented, and the hardware circuit and software implementation of the system are given. In the hardware circuit of the system, each temperature sensor corresponds to the I / O port of the single chip microcomputer, and the temperature sensor is identified by using the I / O port to improve the acquisition frequency. The software realizes the functions of temperature data transmission, display and archiving by compressing the data, reducing the transmission data, improving the wireless transmission efficiency and reducing the power consumption. The experimental results show that the system can collect multiple temperature points simultaneously with a frequency of 1 Hz. The error of acquisition temperature is less than 0.5 鈩，
