The method for controlling the mode under the normal water use condition comprises the following steps: setting a single continuous water consumption threshold under a normal water consumption working condition in a controller; the reed switch sensor collects water flow data and transmits the water flow data to the controller; the controller compares the water flow data acquired by the reed switch sensor with a single continuous water consumption threshold under the normal water consumption working condition; if the collected water flow data exceeds a single continuous water consumption threshold under the normal water consumption working condition, the controller controls the water pipe on-off control valve to be closed;

The method for controlling the mode of the sudden water supply working condition comprises the following steps: setting an automatic water supplementing threshold value of the closestool under the sudden water supply working condition in the controller; the water pressure sensor detects whether water exists in the water inlet pipeline and transmits the water to the controller; if the water pressure sensor firstly transmits a water-free signal to the controller, then transmits a water signal to the controller, and the controller judges a sudden water-supply working condition; the reed switch sensor collects water flow data and transmits the water flow data to the controller; the water pressure sensor detects water pressure state data and transmits the data to the controller; if the water flow data collected by the reed switch sensor does not reach the automatic water supplementing threshold value of the closestool, the water pressure drops again and the controller judges that water is used by people; if the water pressure is stable during the period that the water flow data collected by the reed pipe sensor does not reach the automatic water supplementing threshold of the closestool, the controller judges that the water leakage phenomenon exists after the water flow data collected by the reed pipe sensor reaches the automatic water supplementing threshold of the closestool, and controls the water pipe on-off control valve to be closed.
The specific embodiment is as follows: firstly, under the normal water consumption working condition control mode, a control key 10 is arranged on the controller, the control key is provided with an addition and subtraction key and a reset key, through the addition and subtraction key, a user can set a single continuous water consumption threshold under the normal water consumption working condition, the controller knows the water consumption through the reed switch sensor, the water consumption is compared with the threshold each time, the controller stops using water, the memory value can be automatically cleared for waiting for the next water consumption to be remembered, and the like. If the water consumption of the user at one time occasionally exceeds the set threshold value, the user only needs to turn off the faucet during the water consumption without resetting the set value, the controller can automatically clear the water flow signal transmitted by the reed switch sensor and memorize the water flow signal and immediately turn on the water consumption, if the water consumption of the user at one time occasionally exceeds the set threshold value, the spherical valve is closed, the reset key is needed to be manually pressed to clear the water consumption to release the valve, and the function can prevent the ageing of the indoor pipeline and the water leakage of the connected metal hose due to the burst of the water pressure high pipeline from being reduced to the minimum water leakage.
Secondly, under the drip working condition control mode, the drip metering movement can reach the drip metering standard by utilizing the drip metering movement, if a water pipeline in a user is damaged due to quality problems and the construction process, or a tap is not connected with the pipeline in place, the drip metering movement can drive a gear assembly by means of the connection of an impeller of the drip flow movement impulse movement, the gear assembly is different in size and drives a magnetic head to rotate by a proportional transmission sensing gear, a signal is output to a controller by a matching reed switch sensor, the condition that the drip is stopped by setting the number of 500 milliliters of water for two hours to be a threshold value under the condition that the controller recognizes metering, and the controller considers that the condition of micro-leakage is formed after the time and the water quantity reach the threshold value, and the electric actuator is commanded to stop water supply by manually overhauling the pipeline. At this time, the add-subtract key is pressed at the same time to release the micro-leakage closing valve, or the key is used to open or close the micro-leakage monitoring function to switch each other to use the micro-leakage.
Thirdly, under the sudden water supply condition control mode, when the collective water supply system is shut down, a water faucet is opened and forgets to close, so that a large number of water leakage accidents are prevented after water supply is started: because the product is provided with the water pressure sensor, the water pressure of the water inlet pipeline is monitored, the water pressure is lost after the water is stopped, and the controller considers that the water is stopped. After the period of time, the controller obtains an incoming water signal. At this time, no water flow flows through the movement, 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 indoors.
