The modified structure of the present invention will be described in detail below by way of specific examples.
An intelligent control method of an intelligent water meter comprises a microleakage monitoring method and an explosion-leak monitoring method, wherein the microleakage control method comprises the following steps: when the sensor senses that the water meter impeller rotates and the pressure difference exists on the two sides of the check valve 400 but is smaller than the rated pressure difference, the check valve 400 is in a closed state, because the pressure difference exists in the microleakage, water flow is sprayed onto the impeller through the fine hole 4022 under the driving of the pressure difference and enables the auxiliary impeller 300 to rapidly rotate, when the sensor senses that the auxiliary impeller 300 rotates, timing is carried out through a first timing module of the controller 200, when the time reaches a first rated maximum time for one time, water leakage is determined, at the moment, the electromagnetic valve control module controls the electromagnetic valve 700 to be closed, otherwise, data is cleared through the first timing clear module and enters a waiting period, when the sensor senses that the water meter impeller stops rotating and the pressure difference exists on the two sides of the check valve 400 but is smaller than the rated pressure difference, at the moment, the check valve 400 is in a closed state, because the pressure difference exists in the microleakage, the water flow is sprayed onto the impeller through the fine holes 4022 under the driving of the pressure difference, the auxiliary impeller 300 is enabled to rotate rapidly, the inductor is used for timing through the second timing module of the controller 200 when sensing the rotation of the auxiliary impeller 300, when the second rated maximum time is reached at one time, water leakage is judged, at the moment, the electromagnetic valve 700 is controlled to be closed through the electromagnetic valve control module, otherwise, the data is cleared through the second timing clearing module, and the waiting period is started; the explosion leakage control method comprises the following steps: when the pressure difference exists on the two sides of the check valve 400 but is greater than the rated pressure difference, the check valve 400 opens the auxiliary impeller 300 to rotate, the impeller revolution counting module of the controller 200 counts, when the rated maximum revolution is reached once, water leakage is judged, the electromagnetic valve 700 closes, otherwise, the impeller revolution counting zero clearing module clears the data, and the waiting period is started. By the monitoring method, the water meter can monitor the water leakage of the water pipe, and the monitoring method has the effects of monitoring and judging time periods in a micro-leakage manner and high monitoring precision.
When the impeller of the water meter does not rotate and the auxiliary impeller rotates, the micro-leakage is a very small water leakage phenomenon, and the micro-leakage can be judged in a relatively short time from the fact that the second rated maximum time is less than the first rated maximum time, and the electromagnetic valve is closed. When the water meter impeller and the auxiliary impeller work, the water meter impeller and the auxiliary impeller can only sense the primary rotation time of the auxiliary impeller to judge whether the water meter impeller leaks slightly. Of course, if the impeller of the water meter is not monitored, the judgment of the micro-leakage can be carried out only by sensing the one-time rotation time of the auxiliary impeller.
Simultaneously, in order to complete the intelligent operation, the structure design and the expansion of the intelligent water meter are as follows:

The one-way valve 400 is provided with the fine hole 4022, water passing through the fine hole 4022 can be sprayed onto the auxiliary impeller 300 and rotate the auxiliary impeller 300, and the micro water flow expansion effect is realized through the design of the one-way valve 400 and the fine hole 4022, so that the micro water flow expansion device has the advantages of simple structure and low manufacturing cost. The auxiliary impeller 300 is provided with a sensor for sensing the number of revolutions of the impeller and the time for one-time rotation, and the sensor and the solenoid valve 700 are connected to the controller 200, respectively. The water meter realizes the functions of explosion leakage and micro leakage monitoring of the water meter on the water pipe by combining the auxiliary impeller 300 with the inductor and the controller 200, and water can be cut off timely when the water leakage condition occurs, so that the effect of reducing water resource waste is achieved.
The controller 200 includes an impeller revolution counting module for counting the revolutions of the auxiliary impeller 300 and having a rated maximum revolution within a continuous time, an impeller revolution counting zero clearing module for clearing the count value of the impeller revolution counting module, a rated revolution input module for inputting the rated maximum revolution of the impeller revolution counting module, a first timing module for timing the revolutions of the auxiliary impeller 300 and having a first rated maximum duration within the continuous time, a first timing zero clearing module for clearing the timing value of the first timing module, a first rated timing input module for inputting the first rated maximum duration of the first timing module, a wireless control module, and an electromagnetic valve control module for controlling the electromagnetic valve 700. Through wireless control module, can realize the control to this water gauge through wireless terminal such as cell-phone, the prerequisite of course needs cell-phone installation terminal APP control system, and the system of this type is more ordinary on the market now, so just no need be described redundantly here. And the control range comprises the display of the reading of the water meter, the numerical adjustment of the rated revolution input module and the control of the opening and closing of the electromagnetic valve 700. And then the effect of high-end wireless intelligent operation has been reached.

The diameter of the nozzle hole 4032 is larger than that of the fine hole 4022, the diameter of the second groove 4031 is gradually reduced along the direction from the opening to the nozzle hole 4032, the second groove 4031 is of a cone-like structure, the water flow pressure of the second groove 4031 can be effectively expanded for the second time, and the micro-leakage water flow expansion effect is further guaranteed, and high-precision monitoring is finally achieved. And a sealing ring 405 is provided at the contact of the connection post 4033 with the groove inner wall of the first groove 4021. Compared with the scheme of directly arranging the fine holes 4022 on the valve plate 402, the design of combining the pressure collecting nozzle 403 by the arrangement of the fine holes 4022 has the advantages that the monitoring failure caused by blockage of the fine holes 4022 is prevented, and the installation requirements of the check valve 400 can be effectively reduced by the structure of the first grooves 4021 and the second grooves 4031. And the rotating speed of the impeller is adjusted by adjusting the distance between the nozzle hole 4032 and the impeller, so that the monitoring flexibility and controllability are ensured.
Of course, in the design, in order to ensure the sealing performance, a sealing ring 405 may be provided on the mating contact surface of the first groove 4021 and the connecting column to perform sealing.
Example two:
as is known, the water meter body 100 necessarily has a water meter impeller (not shown), and particularly, a sensor for monitoring the water meter impeller is provided on the intelligent high-end water meter.

The water meter impeller is monitored through the sensor, when the sensor senses that the water meter impeller does not work, the sensor senses that the auxiliary impeller 300 works, and after the auxiliary impeller 300 lasts for a relatively short time, the water pipe microleakage is judged. Of course, the relative shorter is the determination method compared to the first embodiment, and the solenoid valve 700 may be closed. Thereby shortening the time of micro leakage and reducing the waste amount. Other technical features are the same as those of the implementation, and thus are not described herein again.
