Embodiment 1

[0056] like image 3 As shown, this embodiment is implemented according to the following steps:

[0057] 1. The user sends a micro water leakage detection instruction to the smart water meter through the user terminal.

[0058] 2. The smart water meter detects the water flow within 10 minutes.

[0059] 3. Determine whether the water flow within 10 minutes is continuously greater than zero and less than the suspected micro-leakage threshold Q0. If not, then

[0060] 4. Feedback to the user terminal that there is no water leakage. If yes, it is preliminarily judged that there may be a slight water leakage, and then go to step 5.

[0061] 5. Close the water inlet valve.

[0062] On the one hand, it avoids the continued occurrence of micro-leakage, and on the other hand, it continues to execute the secondary judgment to avoid judgment errors.

[0063] 6. The intelligent water meter detects whether the instantaneous pressure drop of the water pressure when the water inlet valv...

Embodiment 2

[0071] This embodiment is implemented on the basis of the first embodiment.

[0072] In this example, as Figure 4 The micro water leakage detection system shown is implemented, the system includes an indoor waterway 1, a smart water meter 3, a number of water equipment 2 and a number of distributed water leakage detection sensors 4, and these distributed water leakage detection sensors 4 are distributed and installed in each water equipment 2. On the waterway, it is used to detect the water leakage of each water equipment 2. It is connected to the smart water meter 3 through the wireless module. After encountering water, the circuit is turned on, and the water leakage detection information is reported to the smart water meter 3 based on the wireless module.

[0073] Based on this system, this embodiment is based on the first embodiment, such as Figure 5 As shown, after step 8, perform the following steps:

[0074] 9. Detect the detection information of the distributed wate...

Embodiment 3

[0081] In this embodiment, the micro water leakage detection is started according to the set time period to ensure the normal water consumption of the user. Specifically, such as Image 6 shown:

[0082] 1. The user sets the specific implementation time period for the smart water meter to start the micro-leakage detection through the user terminal.

[0083] For example, the user may set 3:00 a.m. as the time period for micro-leakage detection through the user terminal APP.

[0084] 2. The smart water meter receives and saves the settings of the user terminal.

[0085] 3. The smart water meter judges the time based on the network connection or its own timing device, and starts the micro water leakage detection at 3:00 in the morning.

[0086] For the specific micro water leakage detection process, refer to Embodiment 1 or Embodiment 2.

[0087] 4. After the micro water leakage detection is completed, the water leakage alarm information is sent to the user terminal.

Abstract

The invention discloses a water leakage detection method and an intelligent water meter, and the method comprises the steps: the intelligent water meter detects the water flow rate in a first set time period, and closes a water inlet valve when the water flow rate is continuously greater than zero and less than a suspected micro water leakage threshold value; the intelligent water meter detects the accumulated pressure drop of the water pressure within a second set duration; when the accumulated pressure drop is larger than a limit value, a micro water leakage alarm is given out. The situation of slow water leakage or micro water leakage at home is monitored by combining judgment of the water flow within the first set time length and judgment of the accumulated pressure drop of the water pressure within the second set time length, and the technical problem that an existing indoor waterway cannot monitor the phenomenon of slow water leakage or micro water leakage is solved.

Description

technical field [0001] The invention belongs to the technical field of smart home, and in particular relates to a water leakage detection method and an intelligent water meter. Background technique [0002] With the increase of working conditions and people's needs, the water meter is not only a single tool for measuring water consumption, but can be equipped with highly targeted intelligent functions according to the use occasion or demand, such as detecting water temperature, water quality, water pressure, water flow, etc. [0003] Among them, obtaining the water flow can reflect the user's water consumption, and at the same time, based on the monitoring of the water flow, it can also know whether there is water leakage in the user's water system, so that an alarm can be prompted, which is helpful for safe water use and water conservation. [0004] However, most of the existing methods for detecting water leakage by monitoring the flow rate of a water meter perform water ...
