摘要
针对目前广域物联网在智能燃气表控制系统存在传输距离短、覆盖范围小、需要基站多等问题,提出了一种基于窄带物联网(NB-IoT)技术传输方式的无线智能燃气表。系统以KL36为微控器,采用BC95无线模块实现功能设计,给出了控制系统详细的硬件和软件设计方法。测试结果表明:利用NB-IoT技术克服了广域物联网存在的问题,系统具有稳定、可靠等优点,有很好的推广前景和应用价值。
Aiming at the problems of short transmission distance,small coverage range and more base stations are needed in intelligent gas meter control system of wide area internet of things,a wireless intelligent gas meter based on narrow-band Internet of things(NB-IoT)transmission mode is proposed.The system uses KL36 as micro controller,uses BC95 wireless module to realize function design,and gives the detailed hardware and software design method of control system.The test results show that the NB-IoT technology overcomes the problems exist in wide area Internet of things,and has the advantages of stability and reliability,it has good prospect and application value.
