Internet of things gas meter

Abstract

Provided is an internet of things gas meter. The gas supply measurement function of the gas meter belongs to the gas meter, and the charge management function belongs to a circuit; a valve which can be automatically switched off without power is installed in a mechanical gas meter, an internet of things communication control circuit is overlaid on the mechanical gas meter, and a center management computer is used for conducting centralized information management on dispersed gas supply through a communication network and an internet of things network; by means of each gas supply unit mechanical switch charging status generated through mechanical detection measurement of the gas meter, energizing is conduced immediately and instantaneously, and after charging is confirmed through internet of things interactive communication and data exchange, a new round of gas supply is conducted; after warning is conducted when the gas supply condition is not met and charged gas capacity continuous to be completely supplied, the valve in the gas meter is automatically switched off without power; management, control and charging all meet the uniform measurement reading conforming to the legislative purpose of the measurement law; internet of things closed-loop payment switching of electronic money and physical commodities is achieved; the major illegal current situations that existing electronic gas meters adopt double measurement, double control and double display, and the whole industry violates the national measurement law in a large scale are thoroughly changed.

Description

technical field [0001] The present invention relates to a flow measurement device; more specifically, it relates to a central management computer that conducts centralized / decentralized management and charging through a wireless mobile communication network and the Internet of Things. The circuit in the device only instantaneously Power-on work, or regular communication to test circuit equipment, real-time protocol encrypted communication and charge management, open the valve installed in the device; when the gas supply conditions are not met, the Internet of Things gas meter that can automatically shut off the valve in the device does not require electricity . Background technique [0002] At present, the publicly known and public Internet of Things gas meters are in the primary stage of research and development, trial and use. One is that the Internet of Things technology, as the 2.0 version of the Internet, is improving its security and the scope of application by leaps ...

Problems solved by technology

Therefore, there is a major structural defect: there are two kinds of measurement data and two kinds of measurement results, mechanical measurement and electronic measurement at the same time! Such measuring instruments are contrary to the legislative purpose of "unified measurement standards" of the Metrology Law, and are illegal measuring instruments! That is to say, the daily gas supply, gas consumption, and payment management are all electronic data, and the measurement, control and display results are mechanical data, while the electronic data is only the electronic pulse alteration in the mechanical detection process; one gas consumption data is two Display, there may be two different metering readings: the fee payment is based on the electronic pulse modification, and the gas used to control the gas supply is also an electronic pulse modification; and the electronic data may be inconsistent with the mechanical data in actual management, and the gas supply pipe gas The department stipulates that when there is inconsistency, the mechanical display data shall prevail, and the electronic data shall only be used as reference data! This kind of industrial and large-scale violation of the fundamental legislative purpose of "unified measurement standards" in the National Metrology Law cannot last for a long time and last forever! 2. Existing IoT gas meters must be powered continuously for 24 hours. Even if it is only a very small power supply in the dormant state of the circuit, the electronic metering pulse must be powered. If the power supply fails, metering, deduction, and valve closing cannot be realized , The IoT gas meter management work will fail and fail! However, at present, even the highest quality batteries in the world have a certain failure rate of sudden death during the normal service life; Supplying current will inevitably lead to the loss of control of the smart gas meter! At present, large-capacity farad capacitors are installed on many smart gas meter circuits. This is the de facto dual power supply, which reduces the occurrence of out-of-control situations, but does not fundamentally solve the problem. Instead, a new gas supply has appeared. Fault phenomena, electronic gas meters often cause gas supply interruption due to power supply problems, and replacing batteries and disassembling gas meters is a labor-intensive and time-consuming process for users and increases management costs. Battery replacement has become a highly professional daily work for electronic gas meters , affecting the gas supply and consumption, increasing the management cost and workload of the gas supply pipeline company

3. Since many gas meters are closed at the user for a long time, the external credit seal of the gas meter is easily damaged, especially the electronic gas meter has a circuit inside. The external credit seal of the gas meter is a big problem, and there are management blind spots
