IoT Water Meter

Abstract

Provided is an internet of things water meter. The water supply measurement function of the water meter belongs to the water 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 water meter, an internet of things communication control circuit is overlaid on the mechanical water meter, and a center management computer is used for conducting centralized information management on dispersed water supply through a communication network and an internet of things network; by means of each water supply unit mechanical switch charging status generated through mechanical detection measurement of the water 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 water supply is conducted; after warning is conducted when the water supply condition is not met and charged water capacity continuous to be completely supplied, the valve in the water 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 water 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 is only instantaneously activated during each round of water supply Electric work, or regular communication to test circuit equipment, real-time protocol encryption communication and charge management, open the valve installed in the device; when the water supply conditions are not met, the Internet of Things water 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 water meter is in the initial stage of research and development trial and use. One is that the Internet of Things technology, as version 2.0 of the Internet, is improving its se...

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 water supply, water use, and payment management are all electronic data, and the measurement, control, and display results are mechanical data, while electronic data is just an electronic pulse modification in the mechanical detection process; one water data can be displayed in two ways, possibly There are two different metering readings: the fee payment is based on electronic pulse alterations, and the control of water supply is also electronic pulse alterations; and the electronic data may be inconsistent with the mechanical data in actual management, and the water supply department stipulates that there are inconsistencies. When unified, the mechanical display data shall prevail, and the electronic data shall be used as reference data only! 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 Internet of Things water 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. The management work of the Internet of Things water meter will fail and fail! However, at present, even the highest quality batteries in the world have a certain failure rate of sudden death within the normal service life; Current, it will inevitably lead to out of control of the smart water meter! At present, large-capacity farad capacitors are installed on many smart water 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, new water supply failures appear. , Electronic water meters often cause water supply interruptions due to power supply problems, and replacing batteries and dismantling water meters is labor-intensive and time-consuming for users and increases management costs. Battery replacement has become a highly professional daily work for electronic water meters, affecting water supply. Increase the management cost and workload of the water supply company

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