With the acceleration of China’s urban modernization, the reform of water, heat, electricity, gas and other energy prices has been the focus of the Central Economic Work Conference in recent years.
Som en framväxande kommunikationsteknik inom Sakernas Internet är NB-iot en ny smalbandig mobilkommunikationsteknik, LPWAN (Low Power Wide Area Network). Den har fördelarna med bred täckning, låg strömförbrukning, låg kostnad, stor anslutning och hög säkerhet. Den är lämplig för långdistanstjänster med låg hastighet och låg strömförbrukning, och har ett brett användningsområde.
On June 16, 2016, the NB-iot technology agreement was approved by 3GPP Wireless Access Network (RAN) Technical Specification Group meeting, and the standardization was successfully completed, indicating that THE NB-iot will soon enter the commercial scale phase. Intelligent water, gas, heat and electricity meter is widely promoted because it can realize real-time energy metering, remote meter reading, remote payment and other functions.Lithium subbattery or IOT battery pack are commonly used in these meters as working and backup power. At the same time, flow meter, gas tester and other intelligent instruments are gradually changing to disposable lithium battery in order to meet the requirements of long service life. It can be said that the development of intelligent instruments in the future will have an increasingly close and inseparable relationship with disposable lithium battery.
