摘　　要：文中设计采用区别于广域物联网的窄带物联网技术进行预付费燃气表的通信传输,解决了广域物联网所需基站多、覆盖范围小的问题。应用NB-IoT技术的预付费燃气表装置的设计采用模块化的方式。主控制器选择MSP430F4152,采用SARA-N2系列模块实现无线数据的传输功能,软硬件设备相互配合,更好地实现数据的实时监测、自动传输、物联网付费及远程调价等功能。通过低功耗测试实验表明,该装置通信性能好,计费测量准确,电能消耗量低,使用寿命长。In this design,the narrow-band Internet of Thing(NB-IoT)technology different from the wide-area IoT is used to carry out the communication transmission of the prepaid gas meter,which solves the problems that the wide-area IoT requires many base stations and has a small coverage. The prepaid gas meter device applying NB-IoT technology is designed in a modular manner. The MSP430F4152 is selected as the main controller,the SARA-N2 series modules are adopted to realize the transmission function of the wireless data,and the hardware and software devices are cooperative with each other to better realize the functions of real-time monitoring and automatic transmission of data,IoT payment and remote price adjustment,etc.The testing experiment results of low-power consumption show that the device has good communication performance,accurate billing measurement,low power consumption and long service life.
