" having the intellectual water meter that multiple anti-power failure is stolen water " of my company's research and development adopted the different electrical power power supply on valve open and close control problem, the user is when removing battery, and valve can close valve accurately, thereby fundamentally stopped to steal the existence of water phenomenon.
(3) utility model content
The purpose of this utility model is: when the user removed battery, the situation that valve can not normally be closed proposed a kind of intellectual water meter that multiple anti-power failure is stolen water that has at present intellectual water meter.
The technical scheme in the invention for solving the technical problem is:
Having multiple anti-power failure steals the intellectual water meter internal control circuit of water and contains: power supply circuit, microcontroller, valve controling circuit, sample circuit, radio-frequency card read/write circuit.In order to realize the user when removing battery, intellectual water meter is valve-off normally, it is characterized in that: microcontroller partly is connected with power supply circuit, valve controling circuit, sample circuit, radio-frequency card read/write circuit etc. respectively.Power supply circuit: adopt dry cell to provide normal working voltage to microcontroller, the positive pole of dry cell is connected with the emitter of triode P1 in addition, for valve controling circuit provides out the valve power supply, the positive pole of dry cell also is connected with the anode of diode D2, the negative pole of dry cell is connected with the negative pole of energy-storage travelling wave tube E1, be connected with the emitter of triode P2 after the negative pole of E1 is connected with the negative electrode of D2, close the valve power supply for valve controling circuit provides.At ordinary times, under the situation of battery electric quantity abundance, utilize the open and close of dry battery power by-pass valve control, when the user removes battery, utilize energy-storage travelling wave tube institute reserve of electricity to close the valve power supply for valve controling circuit provides.Valve controling circuit is made up of triode P1, P2, N1, N2, N3, N4, resistance R 14, R30, R31, R32, R33, R34, R35, capacitor C 17, voltage stabilizing diode D3, D4 and motor valve.Sample circuit adopts goes alone the reed pipe sampling, and microcontroller detects a low level and a high level is an efficiently sampling signal.Principle of work of the present utility model and workflow are as described below: under the normal situation of battery electric quantity, microcontroller has inquired pulse, when being the water consumption of unit volume, examine and make cuts unit volume user's surplus water of controller, when surplus water is not enough in the table, microcontroller is carried out and is closed the valve actuation of an alarm, this moment, the user only needed card is placed on the card induction zone, can resume water supply, if surplus water is 0 in the microcontroller, then microcontroller is carried out the valve closing action, during this period, if the amount of batteries deficiency, after the user would remove battery, utilize energy-storage travelling wave tube E1 institute reserve of electricity to close the valve power supply for valve controling circuit provides, valve can normally be closed.
The utility model internal control circuit cooperates the intellectual water meter structure of my company's patent of invention " but the battery case of early warning power failure and intellectual water meter " accompanying drawing 4 to use.
The beneficial effects of the utility model are:
(1) the utlity model has multiple anti-power failure and steal the intellectual water meter of water and adopt advanced radio-frequency card technology, the management of the use of water theory of the back water of paying dues has earlier been avoided the drawback of manual metering.
(2) the utlity model has intellectual water meter that multiple anti-power failure steals water when the battery electric quantity deficiency is removed battery, utilize the energy-storage travelling wave tube in the circuit to provide power supply, make just normal close valve of intelligent electric meter, thereby stopped illegal user's water phenomenon steathily for closing valve.
(3) the utlity model has multiple anti-power failure, to steal the intellectual water meter of water simple in structure, easy to use, for management of the use of water department and user have brought benefit.
