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.
NB-iot on nouseva viestintäteknologia esineiden internetin alalla, ja se on uusi kapeakaistainen matkapuhelinverkkoon perustuva LPWAN-teknologia (Low power Wide Area Network). Sen etuna on laaja peittoalue, alhainen virrankulutus, alhaiset kustannukset, suuri yhteyskapasiteetti ja korkea turvallisuus. Se soveltuu pitkän matkan, alhaisen virrankulutuksen ja monipäätteiden esineiden internet -palveluihin, ja sillä on laaja valikoima sovellusmahdollisuuksia.
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.
