IoT Smart Water Meter

Abstract

The invention provides intelligent water meters adopting IoT (Internet of Things). Each meter is endowed with a unique code, and a central management computer is used for centralized information management through a mobile information communication network, an internet-IoT network and an offline terminal of an intelligent card network; a fee charging state of each water supply unit is generated through mechanical detection and measurement of the meters, fee charging is confirmed through instant communication and data exchange, and then valves are opened for a new round of water supply, and centralized information management control of water supply of disperse water meters is realized; alarm is performed when conditions of the next round of water supply are not met and surplus water is supplied continuously, and then the valves in the water meters are switched off automatically without an instruction or a power supply; measurement data of the water meters is not subjected to A / D (analog / digital) conversion or is controlled to be not subjected to D / A conversion; only one measurement data is provided for management and fee charging, and the requirement for unified measurement specified in the purpose of legislation of the Metrology Law is met; the current serious illegal situations that electronic water meters adopt double measurement, double control and double display of mechanical / electronic water supply data and the whole industry violates the Metrology Law of China on a large scale possibly end.

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, the Internet, and the Internet of Things. Power-on work, real-time protocol encryption communication and charge management, open the valve installed in the device; the Internet of Things smart water meter that can automatically shut off the valve in the device without power when the water supply condition is not met. Background technique [0002] At present, the publicly known water meters have mainly gone through four generations and are in use at the same time. The first generation is a mechanical water meter. The mainstream mechanical water meter uses "velocity" and "volume method" to measure the volume of water passing through the water meter, and Instantaneous flow and cumulative flow readings are displayed by mecha...

Problems solved by technology

The measurement of mechanical water meters is reliable, but it completely relies on manual door-to-door meter reading, which is highly dependent on data collectors and users. The error rate of manual collection and manual input of original data is high, and the reliability of original data collection is not high; the management methods are primitive and backward, low efficiency

The second generation is electronic meter reading water meters, including remote meter reading water meters and wireless, photoelectric, infrared meter reading and other water meters. It is a mechanical water meter superimposed with non-electrical electrical measuring devices, and the water volume is converted by analog / digital (A / D conversion) into the number of electronic pulses, which are transmitted to the management side with specially installed wires or radio; electronic meter reading water meters usually do not have control valves, only meter reading, no direct charging, no control, and it is a transitional device that lacks management and execution means

This working mode of analog / digital (A / D) and digital / analog (D / A) conversion in mechanical measuring instruments and used for electronic control has major defects: there are two kinds of measurement data and two kinds of measurement results at the same time. ! Contrary to the legislative purpose of "unified measurement standards" of the Metrology Law, it is an illegal measuring instrument! That is, the daily water supply, water use, and payment management are all electronic data. The measurement detection and display results are mechanical data, and the electronic data are only electronic artifacts in the mechanical detection process; one water data has two displays and two different measurement readings : The payment is based on the electronic pulse modification, and the control of water supply is also an electronic pulse modification; and if the electronic data is inconsistent with the mechanical data in actual management, the water supply department stipulates that the data should be displayed mechanically when there is inconsistency 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!

[0004] At the same time, since many water meters have been working at the user's site 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
