NB-IoT燃气表节能和气量告警方法设计

Energy Saving and Gas Volume Warning Method Design For NB-IoT Smart Gas Meter Prepaid Mode

近年来,窄带物联网(NB-IoT)技术的出现推动了相关设备的发展,基于NB-IoT的新型智能燃气表将被逐步推广开来。然而现有的计费方式只是简单的利用表内计算模块,会出现意外断气的情况。为了很大程度上避免由于余额不足导致燃气表关阀从而造成的使用延迟,提升用户的使用体验,同时也满足对NB-IoT智能燃气计费表的低功耗要求,面向预付费模式设计了一种节能和气量告警处理方法。该方法通过减少NB-IoT智能燃气表的同步请求发起次数以及多阈值设置进行用户警报提醒。仿真结果表明,上述方法可以在合理的时间对用户作出余额的提醒从而切实保证用户的使用体验,同时达到进一步降低燃气表能耗的目标。

In recent years, the emergence of Narrowband Internet of Things(NB-IoT) technology has promoted the development of related equipment, and new intelligent gas meters based on NB-IoT will be gradually promoted. However, the existing charging method simply uses the in-table calculation module, and there can be an unexpected gas outage. In order to largely avoid the use delay caused by the insufficient balance of the gas meter, improve the user experience, and meet the low power consumption requirement of the NB-IoT smart gas meter,we designed an energy saving and gas volume alarm processing method based on prepaid mode. The method performs user alarm reminding by reducing the number of synchronization request initiations of the NB-IoT smart gas meter and the multi-threshold setting. The simulation experiment shows that the method can remind the user of the balance at a reasonable time to ensure the user’s experience and achieve the goal of further reducing the energy consumption of the gas meter.
