The specific implementation mode is as follows: firstly, under the normal water use condition control mode, be equipped with control button 10 on the controller, the control button has plus-minus button and reset button, through plus-minus button, the user can set for the continuous water consumption threshold value of single under the normal water use condition, the controller learns the water yield that flows through the tongue tube sensor, and water controller can remember the water consumption at every turn and compare with the threshold value, and the controller that has stopped using water can automatic clear memory value and wait for next water use to remember again, so on and so on the circulation. If the water consumption of a user once at an accident exceeds the set threshold value, the user only needs to close the water faucet in the water using period without changing the set value again, at the moment, the controller cannot obtain a water flow signal transmitted by the reed pipe sensor, the controller can automatically clear and memorize the water flow signal and immediately open the water faucet again, if the water consumption of the user once at an accident exceeds the set threshold value, the ball valve is closed, and the reset key needs to be manually pressed to clear the water excess for closing the valve, so that the function can prevent the water leakage caused by the aging of an indoor pipeline and the burst of a connected metal hose due to a high water pressure pipeline from being reduced to the minimum water leakage.

At this time, the plus-minus key is pressed to release the micro-leakage closing valve, or the micro-leakage monitoring function is switched on or off by the plus-minus key to allow the micro-leakage monitoring function to be used for water leakage.
Thirdly, under the sudden water supply working condition control mode, the water tap is opened after the water supply system stops supplying water, and the water tap is forgotten to be closed, so that a large amount of water running accidents are prevented after the water supply system stops supplying water: because this product is installed water pressure sensor, has monitored inlet channel water pressure, loses water pressure after cutting off the water supply, and the controller thinks the cutting off the water supply. After a period of time, the controller obtains the water coming signal. At this time, no water flows through the machine core, the reed switch sensor does not obtain a signal, the controller considers that the indoor toilet water tank is in a full water state, the faucet is in a complete closing state, and water is normally supplied to the indoor. If water flows through the machine core at the moment, the controller learns that water is supplied to the indoor through the reed pipe sensor, at the moment, the measured flow is set to be not more than 26 liters of water within 90 seconds as a threshold value, the water quantity is used for considering that indoor closestool water is used during the water cut-off period, the closestool can automatically supply water after water comes, at the moment, the controller learns that water flows into the indoor through the reed pipe sensor, monitors and analyzes water pressure condition data during the automatic water supply period of the indoor closestool through the water pressure sensor, and during the automatic water supply period of the closestool, the water pressure drops next time, and the controller believes that the multi-branch water pipe faucet is opened for water. When the water pressure is stable and does not drop again during the automatic water replenishing of the closestool, the controller considers that a faucet is not closed indoors when the water amount flowing into the room exceeds a threshold value, and the controller commands the electric actuator to close the ball valve to stop water supply when the water runs out, so that misjudgment that people use water when the closestool with the incoming water is automatically replenished is accurately analyzed. Under normal conditions, the national standard water-saving closestool can fill the indoor pipe within the time and the water quantity until water does not enter any more. The controller can not obtain the water flow signal transmitted by the reed switch any more to deem that the indoor water valve is normally closed, and then the water flow flows through the indoor water, which is considered as the indoor water, so that the water safety is ensured by the single water consumption set by the user.
Fourthly, an IC card induction coil is arranged, a controller automatically opens a valve after the card is inserted, the controller has the functions of warning and overdraft, when the balance of the IC card is insufficient and the residual water amount is 0, the controller can close the prompting valve through an LED prompting lamp connected with a threshold value, the controller also has the functions of automatically accumulating water consumption, memorizing the power failure, automatically storing and transferring the residual water amount and the accumulated water consumption, when the power failure occurs, the residual water amount can be taken out by a transfer card and transferred to other meters or returned to the original meter, a micro-power consumption display is normally closed, the static working current is less than 16 microamperes, the service life is long, the ball valve can be repeatedly read and written for more than 10 ten thousand times, the anti-blocking function is also realized, when 10 cubic meters of water are consumed, a ball valve switch is prevented from being scaled and blocked and can not rotate for 1 time, a lithium battery is internally arranged, logic encryption is provided according to different requirements of, meanwhile, the IC card can be read through remote transmission without being brushed.
