Technical field

The present invention relates to intellectual water meter field, specially a kind of Multifunctional intelligent water meter.

Background technique

Currently, selling various intellectual water meters in the market, there has been no Multifunctional intelligent water meter, Multifunctional intelligent water meter is to count Measure water while, also have the function of prevention and control surprisingly metal run out, leak, play the role of water conservation, safe water, be show The product being badly in need of for family.

Summary of the invention

The present invention provides a kind of Multifunctional intelligent water meter, the Multifunctional intelligent water meter, including water flow sensor, water level are visited Survey device, wireless encoding signal receiver, single chip machine controlling circuit, power supply, key control panel, liquid crystal display, electrically operated valve, Wireless encoding signal projector, alarm, characterized in that the water flow sensor output signal and single chip machine controlling circuit are defeated Enter end to be connected, the water level detector is connected with single chip machine controlling circuit input terminal, the wireless encoding signal receiver It is connected with single chip machine controlling circuit input terminal, the electrically operated valve is connected with single chip machine controlling circuit output end, the nothing Line coding signal projector is connected with single chip machine controlling circuit output end, the alarm and single chip machine controlling circuit output end It is connected.The water flow sensor uses precision higher elements, and 1 to 100 chong channels will be sent out by flowing through one liter of water.Described presses Key control panel can control opening, closing for electrically operated valve, and can set the disposable maximum flow of Multifunctional intelligent water meter allows to count Amount, can set the disposable flow longest of Multifunctional intelligent water meter allows the time.

Single-chip microcontroller uses memoryless mode, and under normal circumstances, Multifunctional intelligent water meter only records the water flowed through.

When have it is unexpected metal run out, water leakage situation occurs when, the water level on ground reach a certain height, and water level detector is met water and led Logical, single chip machine controlling circuit movement makes electrically operated valve be powered and rotates closing, and electrically operated valve, which realizes, to be automatically closed.It is wireless simultaneously Coded signal emitter emits signal, alarm whistle.The second step precautionary measures are, when have it is unexpected metal run out, water leakage situation When, the water flow of Multifunctional intelligent water meter is flowed through, is more than that the preset disposable maximum flow of Multifunctional intelligent water meter allows Quantity acts single chip machine controlling circuit, and electrically operated valve is powered to rotating and close.The letter of wireless encoding signal projector transmitting simultaneously Number, alarm whistle.The third step precautionary measures are, when have it is unexpected metal run out, water leakage situation occurs when, flow through Multifunctional intelligent water meter Time of flow, be more than that the preset disposable flow longest of Multifunctional intelligent water meter allows the time, make single-chip microcontroller control electricity Road movement, electrically operated valve are powered to rotating and close.Wireless encoding signal projector emits signal, alarm whistle simultaneously.It is wireless to compile Code signal transmitter, wireless encoding signal receiver can be connect with mobile phone or device Host.

The beneficial effect of the invention patent is:

(1) practical to manufacture and design on the basis of original intellectual water meter.

(2) it solves the problems, such as to save water, solve safe water again, be the good product benefited the nation and the people.

Detailed description of the invention

Fig. 1 is Multifunctional intelligent water meter circuit block diagram；

In figure: water flow sensor 1, water level detector 2, wireless encoding signal receiver 3, single chip machine controlling circuit 4, electricity Source 5, key control panel 6, liquid crystal display 7, electrically operated valve 8, wireless encoding signal projector 9, alarm 10

Specific embodiment

Following further describes the present invention with reference to the drawings.

Purpose according to the present invention is to provide a kind of Multifunctional intelligent water meter in the figure, and the water flow sensor 1 is defeated Signal is connected with 4 input terminal of single chip machine controlling circuit out, the water level detector 2 and 4 input terminal phase of single chip machine controlling circuit Connection, the wireless encoding signal receiver 3 are connected with 4 input terminal of single chip machine controlling circuit, the electrically operated valve 8 and monolithic 4 output end of machine control circuit is connected, and the wireless encoding believes that No. 2 transmitters 9 are connected with 4 output end of single chip machine controlling circuit It connects, the alarm 10 is connected with 4 output end of single chip machine controlling circuit.The water flow sensor 1 is higher using precision Element, 1 to 100 chong channels will be sent out by flowing through one liter of water.The key control panel 6 can control opening, closing for electrically operated valve 8 It closes, can set the disposable maximum flow of Multifunctional intelligent water meter allows quantity, can set the disposable flow of Multifunctional intelligent water meter Longest allows the time.

Single-chip microcontroller uses memoryless mode, and under normal circumstances, Multifunctional intelligent water meter only records the water flowed through.

When have it is unexpected metal run out, water leakage situation occurs when, the water level on ground reach a certain height, and water level detector 2 meets water Conducting, single chip machine controlling circuit 4 act, and so that electrically operated valve 8 is powered and rotate closing, electrically operated valve 8, which realizes, to be automatically closed.Simultaneously Wireless encoding signal projector 9 emits signal, and alarm 10 is blown a whistle.The second step precautionary measures are, when have it is unexpected metal run out, leak feelings When condition occurs, the water flow of Multifunctional intelligent water meter is flowed through, most more than the preset disposable flow of Multifunctional intelligent water meter It is big to allow quantity, act single chip machine controlling circuit 4, electrically operated valve 8 is powered to rotating and close.Wireless encoding signal projector simultaneously 9 transmitting signals, alarm 10 are blown a whistle.The third step precautionary measures are, when have it is unexpected metal run out, water leakage situation occurs when, flow through more function The time of flow of energy intellectual water meter is more than that the preset disposable flow longest of Multifunctional intelligent water meter allows the time, makes list Piece machine control circuit 4 acts, and electrically operated valve 8 is powered to rotating and close.Wireless encoding signal projector 9 emits signal, alarm simultaneously Device 10 is blown a whistle.Wireless encoding signal projector 9, wireless encoding signal receiver 3 can be connect with mobile phone or device Host.

The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes Change and improvement all fall within the protetion scope of the claimed invention.Claimed range of the invention by appended claims and Its equivalent thereof.
