| 摘 要： | 现有无线传感器网络节点配备的传感器可测量温度范围有限。为满足煤田火区监测需要，针对应用较普遍的JN5139节点，采用K型热电偶高温传感探头、MAX6675放大与数字转换器，设计一种无线传感器网络高温监测节点。通过SPI接口将MAX6675与 JN5139相连，对数据进行移位和进制转换处理。在不同环境下对高温节点进行测试，结果表明节点测量结果正确、功能正常，并具有较好的扩展性和移植性。

| Abstract: | At present,the measurable temperature range of sensors which is standard configured by Wireless Sensor Network(WSN) nodes is limited.In order to fulfill the demand of coalfield fire area monitoring,a high temperature sensor node of WSN based on JN5139 node that is widely used is designed.Type-K thermocouple and MAX6675 amplification and digital converter are used in the high temperature gathering part.MAX6675 and JN5139 are connected through SPI interface and the shifting and data transmission processing are controlled by JN5139 through software.Results show that the temperatures are confirmed correct in different actual environment and it also has expansibility and portability. |
