Intelligent System Architecture Design Based On Narrowband Internet Of Thing

Narrowband Internet of Things technology has developed into many fields such as sports,medical care,transportation,agriculture,and home furnishings,relying on the advantages of low bandwidth,low power consumption,wide coverage and large number of connections.Narrowband Internet of Things technology has promoted the birth of a batch of Internet of Things devices.With the increase in the number of terminal devices and the gradual expansion of applicat ion scenarios,it will inevitably bring about the diversified needs of communication technology and the pressure of data transmission.At present,the communication scheme of the narrowband Internet of Things system is relatively single,it is difficult to support the fusion of multiple communication technologies,the reliability of data transmission is poor,and the standby time is short under low power consumption.Therefore,this paper designs and implements a low-power narrowband IoT intelligent system architecture suitable for flexible configuration of multiple protocols.The architecture integrates adaptive sliding window technology,multiple narrowband integration,ultra-low power consumption technology,and remote upgrade technology to improve the compatibility,scalability,and stability of the narrowband Internet of Things.Aiming at the problem of the single communication scheme of the narrowband IoT system,a variety of narrowband integrated IoT system models are proposed,which can make the system compatible with multiple communication technologies such as NB-IoT and Power UTC.Aiming at the problem of insufficient data transmission reliability,a narrowband IoT system model with adaptive sliding window communication is designed and implemented.The sliding window management method is adopted to ensure the stability of data transmission through the terminal device network layer.In view of the short standby time under low power consumption,an ultra-low power consumption narrowband IoT software and hardware platform is proposed.Through hardware equipment selection,reasonable battery scheme selection,and stable and fast software business processing functions,The standby time of the system.The intelligent system architecture based on the narrowband Internet of Things designed in this paper has been put into practical application.It has been installed and used in college campuses,community residential buildings,power stations and other places,and has been operating stably for nearly two years.
