The Development History of Smart Gas Meters
Looking at the development of smart gas meters, the development process of smart gas meters from initially only being able to achieve pre - payment and control functions to the current integration of functions such as data sensing, air - based value storage, querying, remote monitoring, and real - time warning has gone through three development stages.
1.Initial Stage - Card type Gas Meters
The IC - card gas meter takes the diaphragm gas meter as the basic meter and realizes the pre - payment function through the IC card. It solves the problem of traditional manual meter - reading and charging, reduces the operating costs of gas companies, and also facilitates users to pay fees.
In the early days, IC - card gas meters had problems such as poor valve reliability, easy corrosion of the card slot, and inability to adjust gas prices in a timely manner due to gas volume hoarding. However, it was still the main form of smart gas meters at that time.
2.Exploration Stage - Remote - reading Gas Meters
After 2000, products such as CPU - card smart gas meters and integrated smart gas meters were successively launched, which improved information storage and security. At the same time, remote - reading gas meters began to develop, including wired remote - reading meters and wireless remote - reading meters. Through communication technologies, remote meter - reading and data transmission were realized, but there were problems such as complex construction and limited coverage.
3.Development Stage - IoT Gas Meters
IoT gas meters achieve functions such as real - time data transmission and remote control through mobile communication networks, and support services such as tiered pricing and safety warnings. In 2017, Shenzhen Gas Group carried out a pilot project of remote meter - reading using NB - IoT technology, marking the entry of NB - IoT smart gas meters into the stage of practical application. The NB - IoT technology has the characteristics of low power consumption, wide coverage, and large connection capacity, further improving the performance and reliability of smart gas meters.
At present, IoT smart gas meters have become the mainstream in the market. IC - card gas meters are gradually being replaced, but some old - fashioned users are still using them.
The smart gas meter industry continues to develop in the direction of intelligence and IoT - connectivity. In the future, more efficient data transmission, a safer gas - using environment, and more convenient user services will be achieved.
