基于6LoWPAN的井下数据采集器设计

Design of underground data collector based on 6LoWPAN

针对目前井下数据采集装置存在功能简单、配置复杂、扩展性差等问题,设计了一种基于6LoWPAN的井下数据采集器。该数据采集器采用CC2530芯片实现井下多种参数的采集和无线收发,并通过移植在CC2530芯片上的Contiki系统6LowPAN协议栈实现UDP通信。测试结果表明,该数据采集器进行基于6LoWPAN的UDP通信时丢包率为0.15%,A/D接口的测量误差在0.2%以内。

For problems of simple functions,complex configuration and poor expandability of existing underground data collector,an underground data collector based on 6LoWPAN was designed.CC2530 chip is used to realize collection and wireless transmission of underground multiple parameters.6LoWPAN protocol stack provided by Contiki system is transplanted in CC2530 chip to realize UDP communication.The test results show that the data collector can realize UDP communication based on 6LoWPAN with packet loss rate of 0.15%and measuring error of A/D interface within 0.2%.
