物联网下智能水表系统的设计与实现

Design and implementation of intelligent water meter system based on internet of things

为解决目前水表的功耗大、信号覆盖低等问题,保证数据安全可靠传输,设计并实现一种基于物联网技术的智能水表系统.该水表以STM8L101F3超低功耗单片机为系统主控芯片,实现对水表流量数据的采集,借助NB-IoT无线网络使用MQTT协议将数据接入阿里云物联网平台,实现数据传输以及远程控制.设计采用蜂窝窄带物联网NB-IoT(narrow band Internet of things)技术,将设备接入阿里云物联网云平台,解决了智能水表数据采集和传输过程中网络吞吐率小、覆盖面积小、功耗大、数据安全性能低等实际问题,不仅实现了水表智能便捷化的管理,更可为未来新型智慧城市的发展提供技术上的支持.

In order to solve the problems of higher power consumption and lower signal coverage,while ensuring the safe and reliable transmission of data,this paper designed and implemented a new intelligent water meter system based on the technology of Internet of Things(IOT),which realize the water meter traffic data collection by using ultra-low power consumption single-chip STML101F3 as the system master control chip system.With the aid of NB-IoT wireless network using the MQTT protocol data access to connect the Ali cloud IoT platform,it achieved data transmission and remote control.This design adopted the technology of Narrow Band Internet of Things(NB-IoT)and connected the equipment to Aliyun Internet of Things Platform to solve the practical problems of limited data throughput,narrow area coverage,high power consumption,lower data security performance and etc.It not only realizes the intelligent water meter management,but also provided technology support for the future development of new smart cities.
