Intelligent tap water meter of self-power supply automatic meter reading capable of remotely cutting off water

Abstract

The invention relates to an intelligent running water meter, wherein the intelligent running water meter does not need an external power supply; the inside of the intelligent running water meter can automatically generate electrical energy; and the intelligent running water meter can remotely control water break and automatically performs meter reading. The intelligent running water meter consists of a Hall switch, an GSM / GPRS module, a singlechip, a microgenerator, a solenoid valve, a drive circuit of the solenoid valve, a standby charging battery, a power supply, a detection circuit of the power supply, a microphone, a display module, an impeller and a gear cluster, wherein the singlechip calculates the water flow rate through the Hall switch, the GSM / GPRS module receives a control instruction and transmits flow data, and the solenoid valve controls water flow; and the microgenerator can convert water-flow kinetic energy into the electrical energy and supplies the electrical energy to the system. The system can analyze flow data in unit time to find the phenomena of water leakage and water seepage, save water, automatically perform meter reading and simultaneously urge users to pay dues in time by means of voice prompt and water break, and particularly can automatically generate the electrical energy for an internal circuit to use and avoid the troubles of power failure, deliberate power-down of users and so on when the external power supply is used.

Description

Technical field [0001] The invention relates to a remote control and unmanned automatic meter reading tap water terminal system, especially an intelligent tap water terminal system that does not need an external power supply and can automatically generate electric energy inside to work for a long time. Background technique [0002] As we all know, the traditional meter reading method of water meters is that the meter reading personnel regularly go door-to-door to copy the data, and then go to each house to ask for it after settlement of the fee. The error is large, the statistical workload is heavy, and there are many human errors, which bring real estate managers and users. Great inconvenience. At present, there is an automatic meter reading system for tap water, which is mainly composed of an electronic flowmeter and a GSM / GPRS module, and can transmit data to the central controller through the GSM / GPRS network to complete the automatic meter reading process, but this auto...

[0002] As we all know, the traditional meter reading method of water meters is that the meter reading personnel regularly copy the data from door to door, and then go to each house to ask for it after the settlement of the fee. The error is large, the statistical workload is heavy, and there are many human errors, which bring real estate managers and users. great inconvenience

At present, there is an automatic meter reading system for tap water, which is mainly composed of an electronic flow meter and a GSM / GPRS module, and can transmit data to the central controller through the GSM / GPRS network to complete the automatic meter reading process, but this automatic meter reading system needs The power supply is provided externally. In the event of a power outage or intentional power outage by the user, there will be a problem of inaccurate measurement.
