Description

Technical Field

[0001] The present invention relates to the technical field of water meters, and in particular to a three-proof smart water meter. Background Art

[0002] With the advancement of intelligent management of urban water supply systems, smart water meters are widely used, and their performance plays a decisive role in the rational use and scientific management of water resources. However, traditional water meters have many problems that are difficult to ignore.

[0003] In terms of waterproof and moisture-proof, the protection measures of traditional water meters are relatively weak. When facing humid environments or accidental flooding, the internal components are easily damaged. Mechanical parts may rust due to moisture and malfunction, and electronic components may also be damaged by water vapor corrosion, which not only seriously affects the measurement accuracy of the water meter, but also greatly shortens its service life.

[0004] Traditional water meters lack effective identification and prevention mechanisms for the problem of reverse installation of water meters. Some users steal water by reverse installation of water meters in order to evade water charges, which not only causes economic losses to water supply companies, but also leads to unnecessary waste of water resources and undermines the fairness and rationality of water resource use.

[0005] In addition, the measurement sensitivity of traditional water meters is low and the starting flow rate is high, making it difficult to detect slight water pipe leaks. In this case, water resources continue to be lost unnoticed, exacerbating the tense situation of water resources.

[0006] In view of this, the present invention proposes a three-proof smart water meter to solve the above problems. Summary of the invention

[0007] In view of this, the present invention proposes a three-proof smart water meter, which can solve the problems of waterproofing and moisture-proofing, preventing the water meter from being inverted, preventing water pipe dripping and users from stealing water, realizing accurate measurement and efficient management of water resources, and significantly improving the reliability and stability of the water meter operation.

[0019] When the water flow rate information is greater than the preset water flow rate threshold, the control module judges that the water meter is used normally.

[0020] Further, when the control module judges the humidity condition of the water meter according to the humidity information and the preset water meter humidity threshold, it includes:

[0021] When the humidity information is within the preset water meter humidity threshold, the control module judges that the water meter humidity is normal;

[0022] When the humidity information is greater than the preset water meter humidity threshold, the control module judges that the water meter has a humidity risk.

[0023] Further, when the control module controls the operating states of the execution module and the alarm module according to the judged installation direction, usage status, and humidity condition of the water meter, it includes:

[0024] When the control module determines that the water meter is installed upside down, and / or when the control module determines that there is a risk of water leakage in the water meter, and / or when the control module determines that there is a risk of moisture in the water meter, the control module controls the execution module to close the water flow and simultaneously controls the alarm module to give an alarm;

[0039] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features described in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0040] With the advancement of intelligent management of urban water supply systems, smart water meters have been widely used. However, traditional water meters have many problems that are difficult to ignore.

[0041] In terms of waterproofing and moisture-proofing, the protection measures of traditional water meters are relatively weak. When facing a humid environment or accidental flooding, the internal components are easily damaged. This not only seriously affects the metering accuracy of the water meter, but also greatly shortens its service life. Traditional water meters lack effective identification and prevention mechanisms. In order to evade water charges, some users steal water by reversing water meters, which not only causes economic losses to water supply companies, but also leads to unwarranted waste of water resources, undermining the fairness and rationality of water resource use.

[0042] In addition, the measurement sensitivity of traditional water meters is relatively low, and the starting flow rate is relatively high, making it difficult to detect minor water pipe leaks. In this case, water resources continue to be lost unconsciously, exacerbating the water resource shortage situation.

[0043] Therefore, the present invention proposes a three-proof intelligent water meter to solve the problems of waterproofing, moisture-proofing, preventing the water meter from being installed upside down, preventing water pipe leaks, and preventing users from stealing water, realizing accurate measurement and efficient management of water resources, and significantly improving the reliability and stability of the water meter operation.

[0044] Refer to Figure 1 , in some embodiments of the present application, a three-proof intelligent water meter includes: a detection module, a measurement module, a protection module, a control module, an execution module, and an alarm module.

[0045] Specifically, the detection module real-time detects the water flow direction information at the water meter inlet and sends the water flow direction information to the control module; the measurement module real-time collects the water flow rate information at the water meter outlet and sends the water flow rate information to the control module; the protection module real-time monitors the humidity information of the water meter and sends the humidity information to the control module.

[0046] Specifically, the detection module is arranged inside the water meter inlet; the measurement module is arranged at the water meter outlet; the protection module is precisely matched with the size and structure of the water meter.

[0047] Specifically, the measurement module adopts a high-precision flow measurement chip and combines advanced digital signal processing technology to accurately measure minute flow rates, enabling the measured flow rate of the water meter to reach below 1 L / h, greatly improving the measurement sensitivity of the water meter.

[0048] Specifically, the control module is electrically connected to the detection module, the measurement module, the protection module, the execution module, and the alarm module respectively.

[0049] Specifically, the control module judges the installation direction of the water meter according to the water flow direction information transmitted by the detection module and the preset normal water flow direction, and also judges the usage status of the water meter according to the water flow rate information transmitted by the measurement module and the preset water flow rate threshold; it also judges the moisture condition of the water meter according to the humidity information and the preset water meter humidity threshold.

[0050] It can be understood that the installation direction of the water meter includes normal direction and upside-down installation, the usage status of the water meter includes normal usage and risk of water leakage, and the moisture condition of the water meter includes normal humidity and risk of moisture.

[0051] Specifically, the control module controls the operation status of the execution module and the alarm module according to the judged installation direction, usage status, and moisture condition of the water meter.

[0052] Specifically, the control module receives the information transmitted by the detection module, the metering module, and the protection module in real time, and compares the received information with the preset water flow direction, water flow rate threshold, and water meter humidity threshold. Once the control module detects abnormal information, it immediately makes a judgment and controls the operating states of the execution module and the alarm module to restore the water meter to its normal operating state.

[0053] It can be seen that through the mutual cooperation of the control module with the detection module, the metering module, the protection module, the execution module, and the alarm module, the present invention can promptly detect abnormal conditions of the water meter, effectively prevent the water meter from being installed upside down, leaking water, and solve the problem of the water meter being at risk of getting wet, thereby improving the reliability and stability of the water meter.

[0054] Reference Figure 1 , in some embodiments of the present application, when the control module determines the installation direction of the water meter based on the water flow direction information transmitted by the detection module and the preset normal water flow direction, it includes:

[0055] When the water flow direction information transmitted by the detection module is consistent with the preset normal water flow direction, the control module determines that the water meter is normal.

[0056] When the water flow direction information transmitted by the detection module is inconsistent with the preset normal water flow direction, the control module determines that the water meter is installed upside down.

[0057] It can be understood that the preset normal water flow direction is the water flow direction when the water meter is normally installed. Once the water flow direction information is inconsistent with the preset normal water flow direction, it indicates that the installation direction of the water meter is abnormal, and the control module will determine that the water meter has a risk of being installed upside down.

[0058] Reference Figure 1 , in some embodiments of the present application, when the control module determines the usage status of the water meter based on the water flow rate information transmitted by the metering module and the preset water flow rate threshold, it includes:

[0059] When the water flow rate information is within the preset water flow rate threshold, the control module determines that the water meter has a risk of leaking water.

[0060] When the water flow rate information is greater than the preset water flow rate threshold, the control module determines that the water meter is in normal use.

[0061] It can be understood that when the water meter is in normal use, the water flow has a certain water flow rate. The preset water flow rate threshold is the minimum water flow rate when the water meter is in normal use. When the detected water flow rate information is within the preset water flow rate threshold, it indicates that the water flow rate is extremely small, and the control module will determine that the water meter has a risk of leaking water and control the execution module and the alarm module to promptly send a message prompt and restore the water meter to its normal operating state.

[0062] Reference Figure 1, in some embodiments of the present application, when the control module determines the moisture condition of the water meter according to the humidity information and the preset water meter humidity threshold, it includes:

[0063] When the humidity information is within the preset water meter humidity threshold, the control module determines that the water meter humidity is normal.

[0064] When the humidity information is greater than the preset water meter humidity threshold, the control module determines that the water meter has a moisture risk.

[0065] Specifically, the water meter humidity threshold is set to 60% relative humidity to ensure that the humidity sensor can accurately and reliably monitor the internal humidity change.

[0066] Reference Figure 1 , in some embodiments of the present application, when the control module controls the operating states of the execution module and the alarm module according to the judged installation direction of the water meter, the usage state of the water meter, and the moisture condition of the water meter, it includes:

[0067] When the control module determines that the water meter is installed upside down, and / or, the control module determines that the water meter has a leakage risk, and / or, the control module determines that the water meter has a moisture risk, the control module controls the execution module to close the water flow and simultaneously controls the alarm module to give an alarm.

[0068] When the control module determines that the water meter direction is normal and the water meter is in normal use, the control module controls the execution module to open the water flow.

[0069] It can be understood that when problems such as the water meter being installed upside down, leakage risk, and moisture risk occur, it is necessary to close the water flow and give an alarm to prevent the water flow from flowing out normally and protect water resources. After the problems of the water meter being installed upside down and leakage are solved, it is necessary to open the water flow to restore the water meter to its normal use state.

[0070] Reference Figure 1 , in some embodiments of the present application, the normal water flow direction, water flow rate threshold, and water meter humidity threshold of the water meter are preset in the control module.

[0071] Reference Figure 1 , in some embodiments of the present application, the execution module includes an electric shut-off valve.

[0072] Specifically, when the control module controls the execution module to close the water flow, it includes: the control module controls the electric shut-off valve to block the water flow; when the control module controls the execution module to open the water flow, it includes: the control module controls the electric shut-off valve to open the water flow.

[0073] Specifically, the electric shut-off valve is installed at the water outlet of the water meter to ensure that the opening and closing direction of the valve is completely consistent with the water flow direction. The electric shut-off valve adopts a high-precision electric actuator and has the ability to quickly respond to control signals and can block the water flow instantly.

[0074] It is understandable that by controlling the electric shut-off valve to block the water flow, the phenomenon of water theft caused by the reverse installation of the water meter and water leakage of the water meter can be effectively prevented.

[0075] Reference Figure 1 , in some embodiments of the present application, the alarm module includes an audible and visual alarm and a wireless communication component.

[0076] Specifically, when the control module controls the alarm module to give an alarm, it includes: the control module controls the audible and visual alarm to give an audible and visual alarm, and the control module controls the wireless communication component to send an information prompt to the management department.

[0077] Specifically, the information prompt sent by the wireless communication component to the management department includes text messages and voice calls.

[0078] It is understandable that by sending an alarm message to the management department, the specific situation of the reverse installation of the water meter is detailedly informed, so that the management department can take corresponding measures in a timely manner.

[0079] Reference Figure 1 , in some embodiments of the present application, the control module includes a processor and a memory; the detection module is configured with an electromagnetic induction type water flow direction sensor; the metering module is configured with a thermal flow sensor; the protection module is configured with a humidity sensor.

[0080] Specifically, the electromagnetic induction type water flow direction sensor is installed inside the water inlet of the water meter. Ensure that the magnetic field direction of the sensor is perpendicular to the water flow direction to obtain the best induction effect.

[0081] Specifically, the thermal flow sensor is accurately installed in the water flow channel of the water meter to ensure that the water flow can evenly and smoothly flow through the heating element and the temperature detection element of the sensor.

[0082] Specifically, the humidity sensor is installed at a position inside the water meter where the humidity is easy to detect, such as above the electronic component board.

[0083] Reference Figure 1 , in some embodiments of the present application, the protection module includes a protective housing, and the protective housing is used to prevent moisture from invading the inside of the water meter.

[0084] Specifically, the protective housing is made of PC-ABS alloy material to ensure the waterproof performance of the protective housing.

[0085] It can be seen that through the setting of the detection module, the present invention can detect the water flow direction of the water meter in real time, and through the setting of the control module, it can achieve rapid and accurate detection of the inverted installation situation of the water meter. Once the control module determines that the water meter is inverted, it will immediately control the electric cut-off valve to block the water flow and give an audible and visual alarm. At the same time, it will send an alarm message to the management department to prompt the water meter to return to the normal use state, effectively curbing the behavior of users stealing water by inverting the water meter and effectively safeguarding the interests of water supply enterprises and the normal order of water resource management.

[0086] Through the setting of the metering module, the present invention can accurately detect minute flow rates, timely discover water pipe leakage phenomena, and effectively avoid waste of water resources. At the same time, the intelligent recognition function for abnormal flow patterns further enhances the ability to prevent users from stealing water, improves the reliability of the water meter, and promotes the rational utilization of water resources.

[0087] Through the setting of the protection module, the present invention can monitor the humidity information of the water meter in real time. It can not only timely discover abnormal humidity conditions of the water meter, but also effectively prevent moisture from invading the interior of the water meter, providing all-round protection for mechanical and electronic components. It significantly improves the stability and reliability of the water meter in humid or waterlogged environments, greatly extends the service life of the water meter, and ensures consistent measurement accuracy.

Moreover, the present application can take the form of a computer program product implemented on one or more computer-usable storage media (including but not limited to disk memories, CD-ROMs, optical memories, etc.) containing computer-usable program codes.

[0090] These computer program instructions can also be stored in a computer-readable memory that can direct a computer or other programmable data processing apparatus to work in a particular manner, such that the instructions stored in the computer-readable memory produce a manufacture including the instruction gardening device, and the instruction gardening device implements the processes Figure 1 one process or multiple processes and / or blocks Figure 1 the functions specified in one block or multiple blocks.
