IoT Smart Gas Meter

Abstract

An internet of things intelligent gas meter is characterized in that a sole code is provided for each gas meter, a center management computer performs integrated information management through a mobile information communication network, an internet of things and an intelligent card network offline terminal, the due charge state of each gas supply unit is measured by mechanical detection of the gas meter, new-round gas supply is performed by opening a valve after instant communication and data exchange charge confirmation, integrated information management control of dispersed gas meter gas supply is achieved, an alarm is given when next-round gas supply conditions are not met, the valve in the gas meter is automatically cut off without instructions or power after residual gas is supplied, measured data of the gas meter are not subjected to A / D (analog to digital) conversion, control is not subjected to D / A (digital to analog) conversion, management and charge only have one type of measured data meeting unified measurement requirements of metrological law legislation objectives, and the major law violation status quo of industry-wide large-scale national metrological law violation of electronic gas meters using mechanical / electronic gas supply data for double measurement, double control and double display is possibly finished.

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

AI Technical Summary

Problems solved by technology

Mechanical gas meter measurement 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 gas meter, including remote meter reading gas meter and radio, photoelectric, infrared meter reading and other gas meters. Convert (A / D conversion) into electronic digital signals, use specially installed wires or use radio to transmit to the management side; electronic meter reading gas meters usually do not have control valves, only meter reading, no direct charging, no control, lack of management implementation means of transition equipment

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 gas supply, gas consumption, and payment management are all electronic data, the measurement and display results are mechanical data, and the electronic data are only electronic alterations in the mechanical detection process; one gas consumption data has two displays, 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 if the electronic data is inconsistent with the mechanical data in actual management, the gas supply pipe department will stipulate that there is inconsistency 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!

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