Description

Technical Field

[0002] Water resources have become a hot topic. Water is a special and irreplaceable resource, as well as a reusable and renewable one. With continuous social progress and development, the uneven spatial distribution of water resources in my country has increasingly become a significant constraint on the country's socio-economic development. Along with rapid economic development, people's demands for water supply quality and the reliability of water supply systems are constantly increasing. To ensure water supply stability, two water sources are usually set up: a main water source and a backup water source. When the main water source is insufficient, the valve of the backup water source can be opened to supply water through it. However, when water is supplied through the main water source, there may be leaks in the valve of the backup water source. Simultaneous supply from both sources may lead to water pressure irregularities, affecting normal water supply. Therefore, how to automatically determine if a valve is leaking and repair it promptly is of great significance for improving water supply stability. Summary of the Invention

[0016] Optionally, the water supply system further includes a second variable frequency water pump disposed between the water storage device and the water supply pipeline;

[0017] The method further includes:

[0024] If the water level is lower than the second preset water level threshold, a water shortage alarm message will be generated.

[0025] Secondly, this disclosure provides a valve leakage detection device applied to a water supply system, wherein the water supply system includes a backup water source and a valve, and a main water source, a water storage device, a first variable frequency water pump, and a water supply pipeline connected in sequence. The backup water source is connected to the water supply pipeline and the first variable frequency water pump respectively through the valve. The first variable frequency water pump is used to transport water from the main water source in the water storage device to the water supply pipeline. The device includes:

[0026] The detection module is used to detect the inlet pressure of the water pipeline in real time;

[0027] The control module is used to reduce the frequency of the first variable frequency water pump multiple times if the inlet pressure is greater than the preset pressure, and to obtain the inlet pressure of the water pipeline after each reduction of the frequency, wherein the water supply pressure of the backup water source is greater than the preset pressure.

[0041] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0042] It should be noted that all actions involving the acquisition of signals, information, or data in this disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the location is situated, and with authorization from the owner of the relevant device.

[0043] Figure 1 This is a block diagram illustrating a water supply system according to an exemplary embodiment. For example... Figure 1 As shown, the water supply system includes a backup water source 1, a valve 2, a main water source 3, a water storage device 4, a first variable frequency water pump 5, and a water supply pipeline 6. The main water source 3, the water storage device 4, the first variable frequency water pump 5, and the water supply pipeline 6 are connected in sequence, and the backup water source 1 is connected to the water supply pipeline 6 and the first variable frequency water pump 5 through the valve 2.

[0044] Water supply pipeline 6 is used for domestic or industrial water use. Water storage equipment 4 can be a water storage tank, water storage vessel, etc. The first variable frequency water pump 5 is used to transport water from the main water supply source 3 in the water storage equipment 4 to the water supply pipeline 6. When supplying water to the water supply pipeline 6, the first variable frequency water pump 5 dynamically adjusts its operating frequency according to the water consumption to maintain the inlet pressure of the water supply pipeline at a preset pressure (e.g., 0.55 MPa), thereby achieving stable water supply. The water supply pressure of the backup water source is greater than the preset pressure.

[0045] Figure 2 This is a flowchart illustrating a valve leakage detection method according to an exemplary embodiment, wherein the method can be applied to the aforementioned water supply system. Figure 2 As shown, the valve leakage detection method may include the following S201 to S203.

[0046] In S201, the inlet pressure of the water pipe is monitored in real time.

[0047] In this disclosure, the inlet pressure of the water pipe can be obtained by a pressure sensor installed at the inlet of the water pipe.

[0048] In S202, if the inlet pressure is greater than the preset pressure, the frequency of the first variable frequency water pump is reduced multiple times, and the inlet pressure of the water pipeline is obtained after each frequency reduction.

[0049] In S203, the valve is checked for leaks based on the change in the inlet pressure of the water pipe after each reduction in frequency.

[0050] In this disclosure, when the valve cavity of the backup water source leaks, the inlet pressure of the water pipe equals the supply pressure of the backup water source. At this time, the inlet pressure of the water pipe is greater than the preset pressure (the supply pressure of the backup water source is greater than the preset pressure). Therefore, when the inlet pressure is greater than the preset pressure, it may be due to leakage in the valve cavity. Thus, when the inlet pressure of the water pipe is greater than the preset pressure, the frequency of the first variable frequency water pump can be reduced multiple times consecutively, and the change in the inlet pressure of the water pipe after each frequency reduction can be observed to determine whether the valve is leaking based on the changes each time.

[0051] Specifically, if the inlet pressure of the water pipe does not change after each reduction in frequency, then the valve is confirmed to be leaking; otherwise, the valve is confirmed to be not leaking.

[0052] In the above technical solution, when the inlet pressure of the water pipeline is greater than the preset pressure, the frequency of the first variable frequency water pump is reduced multiple times, and the inlet pressure of the water pipeline is obtained after each reduction in the frequency of the first variable frequency water pump. This allows for the automatic determination of whether the valve is leaking based on the changes in the inlet pressure of the water pipeline after each reduction in the frequency of the first variable frequency water pump, facilitating timely valve repair and improving water supply stability. Furthermore, determining whether the valve is leaking based on the changes in the inlet pressure of the water pipeline after multiple frequency reductions improves the accuracy of valve leakage detection.

[0053] The following is a detailed explanation of the specific implementation method for determining whether a valve is leaking based on the change in the inlet pressure of the water pipe after each reduction in frequency, as described in S203 above. Specifically, if the inlet pressure of the water pipe does not change after each reduction in frequency, then the valve is determined to be leaking.

[0054] In one possible implementation, prior to the steps of repeatedly reducing the frequency of the first variable frequency water pump, the valve leakage detection method may further include the following steps:

[0055] Determine if the first variable frequency water pump has malfunctioned;

[0056] If the first variable frequency water pump does not malfunction, then the process of reducing the frequency of the first variable frequency water pump is repeated multiple times.

[0057] When the inlet pressure of the water pipeline exceeds the preset pressure, the system does not directly determine whether the valve is leaking. Instead, it first checks whether the first variable frequency water pump is malfunctioning. If the first variable frequency water pump is not malfunctioning, the system then checks for valve leaks, which involves repeatedly reducing the frequency of the first variable frequency water pump. If the first variable frequency water pump is determined to be malfunctioning, then the system determines that the inlet pressure of the water pipeline exceeding the preset pressure is due to a faulty first variable frequency water pump. This allows for quick identification of the cause of the water pressure change, enabling timely implementation of appropriate measures to further improve water supply stability.

[0058] The following is a detailed description of the specific implementation method for determining whether the first variable frequency water pump has malfunctioned. Specifically, it can be determined through the following steps (1) and (2):

[0059] Step (1): Increase the frequency of the first variable frequency water pump and obtain the inlet pressure of the water pipeline after increasing the frequency.

[0060] Step (2): If the inlet pressure of the water pipe after increasing the frequency is equal to the inlet pressure of the water pipe before increasing the frequency, then it is determined that the first variable frequency water pump has not malfunctioned.

[0061] When the inlet pressure of the water pipe exceeds the preset pressure, the frequency of the first variable frequency water pump can be increased to determine whether the first variable frequency water pump has malfunctioned based on the change in the inlet pressure of the water pipe. If the inlet pressure of the water pipe does not change before and after increasing the frequency, it indicates that the change in the inlet pressure of the water pipe is not caused by a malfunction of the first variable frequency water pump, and in this case, it is determined that the first variable frequency water pump is not malfunctioning. If the inlet pressure of the water pipe changes before and after increasing the frequency, it indicates that the change in the inlet pressure of the water pipe is caused by a malfunction of the first variable frequency water pump, and in this case, it is determined that the first variable frequency water pump has malfunctioned.

[0062] like Figure 3As shown, the above-mentioned water supply system may further include a second variable frequency water pump 7 installed between the water storage device 4 and the water supply pipeline 6. The first variable frequency water pump 5 is the main water pump, and the second variable frequency water pump 7 is the standby water pump. When the first variable frequency water pump 5 fails, the second variable frequency water pump 7 can be started to ensure normal water supply and further improve water supply stability. Specifically, the above method may also include the following steps:

[0063] If the first variable frequency water pump fails, the second variable frequency water pump will be controlled to operate, so as to transport water from the main water supply source in the water storage equipment to the water supply pipeline.

[0064] In one possible implementation, the above method may further include the following steps:

[0065] If the valve leaks, a leak alarm message will be generated.

[0066] In this disclosure, leakage alarm information can be issued in the form of sound, flashing lights, messages, etc., to remind staff to repair valves in a timely manner and ensure water supply stability.

[0067] In one possible implementation, the above method may further include the following steps:

[0068] Real-time monitoring of water levels in water storage equipment;

[0069] If the water level is higher than the first preset water level threshold, an overflow alarm message will be generated;

[0070] If the water level is lower than the second preset water level threshold, a water shortage alarm message will be generated.

[0071] In this disclosure, the water level of the water storage device can be monitored in real time by a water level sensor installed in the water storage device; when the water level of the water storage device is higher than a first preset water level threshold, an overflow alarm message is generated to remind staff to take appropriate measures to avoid safety problems caused by overflow and to avoid water waste; when the water level of the water storage device is lower than a second preset water level threshold, a water shortage alarm message is generated to remind staff to take appropriate measures to avoid water supply interruption and improve water supply stability.
