Water meter, with M_bus data remote transmission function, used for tiered pricing

Abstract

The invention discloses a water meter, with an M_bus data remote transmission function, used for tiered pricing. The water meter comprises a water meter base body, a water meter single-chip microcomputer, a clock module, a flow sensor metering circuit, a radio frequency card communication circuit, a UART serial communication circuit and an executor, wherein the clock module, the flow sensor metering circuit, the radio frequency card communication circuit, the UART serial communication circuit and the executor are connected with the water meter single-chip microcomputer. A UART serial port of the water meter single-chip microcomputer is connected with a former-level M_bus concentrator through the UART serial port communication circuit, the radio frequency card communication circuit is connected with a radio frequency IC card of a user in an induction mode and is connected with a corresponding signal end of the water meter single-chip microcomputer, and a control signal output end of the water meter single-chip microcomputer is connected with the control signal input end of a valve in the water meter base body through the executor. All kinds of meters are connected through M-buses, and therefore wiring and connection in energy-consuming intelligent management systems in residence communities, office spaces and the like are greatly simplified. The water meter has the advantages of being simple in structure, low in manufacturing cost and high in reliability.

Description

technical field [0001] The invention relates to the field of instrument energy consumption monitoring, in particular to an energy consumption intelligent management system using MBus for various instruments or related devices, in particular to a water meter with M_bus bus data remote transmission function for ladder pricing. Background technique [0002] The meter bus (MBus) is a new type of bus structure. The main feature of MBus is to simultaneously supply power and transmit serial data through two non-polar transmission lines, and each substation (confirmed with a different ID) is connected in parallel on the MBus bus . When MBus is used in the energy consumption intelligent management system of various instruments or related devices, relevant data or signals can be collected and transmitted.

AI Technical Summary

Problems solved by technology

[0003] At present, the meters installed in residential quarters, office places and other areas usually do not carry out energy consumption management, and use manual meter reading for data collection. Modeling, analysis, planning, etc. all bring great difficulties

In addition, manual meter reading cannot achieve timely meter reading, and it is not easy to implement monthly step-by-step billing
