NB-IoT smart gas meter solution

According to the national 'Thirteenth Five-Year PlanThe deepening transformation of the system further promotes the development of natural gas. The proportion of natural gas in the primary energy consumption structure has increased from 5.9% in 2015 to 9%-10% in 2020. The pipeline network construction has increased by 40,000 kilometers, with an average annual growth rate. 10%. The gasification population increased by 140 million to 470 million, an increase of 42%, and the average annual growth rate increased by 10%. The natural gas field will usher in new opportunities for rapid development. Faced with the rapid development of the meter reading industry, traditional smart gas meters have many problems in solving the pain points of gas customers, such as unstable data transmission, high power consumption, and low meter reading success rate. And NB-IoT has the characteristics of high security, wide coverage, large connection, low power consumption and low cost, which can better solve the above problems and better meet the development needs of gas customers. Common problems in the gas industry 1. Difficulty in meter reading, difficulty in charging, and payment 2. Poor supply and sales of pipe network, transmission and distribution leakage 3. Physical leakage of pipe network, measurement error of meters 4. User stealing gas 5. Gas pipe Network security 6. Complicated tiered price billing, frequent price adjustments, and accurate measurement basis. At present, ordinary mechanical watches account for 60%-70% of the stock in the gas meter market in my country, and the rest are various types of smart meters, most of which are IC Card prepaid smart meter. The following are the characteristics of various types of meters: 1. Ordinary mechanical meters: mechanical metering is not intelligent, requiring manual meter reading 2. IC card prepaid meters: prepaid, single household control, requiring cards as a medium 3. Wired remote transmission meters: Requires wiring in advance and wired connection 4. Short-distance wireless meter: point-to-point or centralized reading, remote control 5. GPRS Internet of Things meter: based on GPRS cellular network, timing reading, remote control Compared with NB-IOT gas meters, smart gas meters The disadvantages are as follows: 1. Data stability. Since many smart meters use technologies such as small wireless for smart meter transmission, they use an ad hoc network established by an unlicensed spectrum, and their data stability, security, and reliability are worrying. 2. High power consumption; if an external power supply is required, communication costs will be increased. For example, the built-in battery will consume too much power, and frequent battery replacement will increase maintenance costs. 3. Network coverage issues: Many domestic gas meters are installed in corridors, indoors or underground, and the installation environment is relatively complex, causing over-standard rates and instability, so the network requirements are high. 4. Capacity issue: In an environment with a high installation density of gas meters, the current network cannot meet the simultaneous access of high-density equipment. NB-IoT gas meters can help gas meter companies reduce meter reading costs, real-time data analysis, scientific meter management, timely troubleshooting, reduce operating costs, and improve operating efficiency; 1. Data security and reliability: NB-IoT is based on The network established by authorized spectrum has high security guarantee in terms of anti-interference ability, data security, technical service, etc., and it is easy to promote at the same time. 2. Low power consumption: NB-IoT has the characteristics of low power consumption. Taking Sanhuo Communication NB-IoT gas meter as an example, its built-in battery can be used for the meter to work normally for more than 8 years. 3. Network coverage: NB-IoT has the characteristics of wide coverage and deep coverage, which can solve the problem of complex gas meter installation environment. 4. Large capacity: NB-IoT has a large capacity, which can meet the simultaneous access of a large number of devices. In the future, not only gas meters need to be connected to the Internet, but also water meters, electricity meters, door locks, trash cans, manhole covers, street lights and other equipment need to be connected to the Internet. NB-IoT's low power consumption, wide coverage, large capacity, and low cost will help. The Internet of Things realizes the connection of all things faster.
