The temperature of mine is related to mine safety and miners ’ health.Currently, in the monitoring of the temperature of mine , there are some problems like limitations of wire wiring ,not flexible of wireless distribu-tion network and waste of energy .To solve these problems ,there is a design based on the ANT protocol of wire-less sensor network .The program based on wireless sensor network principles , a small system is designed consti-tuted by eight nodes terminal and a receiving terminal based on the nRF 24AP2,with the use of RS232 bus to exchange data with the host computer .Finally,the data are displayed on the computerthrough the interface which is programmed by Labwindows /CVI.After testing,the data is correct and the performance of this system com-plies with the requirements .%矿井环境温度是关乎矿井安全及矿工身体健康的主要因素。目前，在矿井温度监测中，存在有线布线局限，无线布网不灵活，能源浪费等问题。针对这些问题，提出了基于ANT技术的无线传感器网络设计方案。该方案根据无线传感器网络设计原理，以nRF24 AP2芯片为基础设计了8个节点终端和一个接收终端组成的小规模系统，并用RS232总线与上位机进行数据交换，最终通过上位机上Lab-Windows/CVI编写的显示界面实现数据显示。经检测，数据显示准确且系统性能符合初步设计的要求。
