Thus, it solves the problem of the inability to achieve intelligent and automated control of the water supply in the prior art.
[0024] Specifically, Figure 1 This is a schematic diagram of an intelligent water supply and control leakage detection device provided in an embodiment of this application.
[0025] like Figure 1 As shown, the intelligent water supply and control leakage detection device 10 includes: a water supply pipeline network 11, an intelligent solenoid valve group 12, a distributed leakage monitoring network 13, a human body sensor 14, and an intelligent controller 15.

Based on at least one of the human body detection signal of the human body detection sensor 14 and the leakage detection signal of the distributed leakage monitoring network 13, the controller controls the opening and closing of the intelligent solenoid valve assembly 12 to realize the water supply control of the water supply pipeline network 11.
[0027] It is understood that, in this embodiment of the application, by setting up an intelligent solenoid valve group 12 and a distributed leakage monitoring network 13 on the water supply pipeline network 11, and setting up a human body detection sensor 14 around the water supply pipeline network 11, the intelligent controller 15 controls the opening and closing of the intelligent solenoid valve group 12 by at least one of the detection signals from the human body detection sensor 14 and the leakage detection signals from the distributed leakage monitoring network 13, so as to realize timely detection of leakage and timely cutting off of water source, realize intelligent and automated management of water supply, effectively prevent water waste and avoid potential safety hazards.
[0028] Among them, the intelligent solenoid valve group 12 can be a bistable 24V DC solenoid valve, which can be installed downstream of the main inlet valve of the water supply pipeline.
[0029] Furthermore, the water supply network 11 includes water pipes, inlets, inlet valves, and water terminals.
[0030] Among them, the water terminal is the final link in the entire water supply process, which is the equipment or location where the water is finally used.
[0031] Furthermore, the distributed leak monitoring network 13 includes multiple leak detection sensors.
[0032] The distributed leakage monitoring network 13 of this application embodiment includes multiple leakage detection sensors to improve the accuracy of leakage detection. The leakage detection sensors can be set at locations prone to leakage or at intervals of a certain distance (e.g., 0.8m).
[0033] Furthermore, the leak detection sensor consists of a pressure sensor, a humidity sensor, and an acoustic detection unit.
[0034] The leakage detection sensor in this application embodiment is composed of a pressure sensor, a humidity sensor, and an acoustic detection unit, which simultaneously detects leakage through multiple methods to improve the accuracy of leakage detection.
[0035] Specifically, the system collects water pressure fluctuation signals in real time through a pressure sensor, humidity change signals through a humidity sensor, and abnormal vibration signals of the pipeline through an acoustic detection unit. These signals are combined to determine the leak detection signal. Among them, the acoustic detection uses frequency domain analysis to identify abnormal sound patterns in the pipeline from 20Hz to 2kHz, distinguishing between normal water use and leakage.
[0036] Furthermore, the human body detection sensor is a photoelectric diffuse reflection sensor.
[0037] Furthermore, the intelligent controller 15 includes a power conversion module, a programmable control unit, and a relay unit. The programmable control unit analyzes data and generates control commands, while the relay unit drives the intelligent solenoid valve group, start / stop buttons, and linkage alarm devices.
[0038] The intelligent controller 15 of this application embodiment includes a power conversion module, a programmable control unit, and a relay unit. The programmable control unit is used to analyze the data of the water leakage detection sensor and the human body detection sensor and generate control commands. The relay unit drives the intelligent solenoid valve group, the start / stop button, and the linkage alarm device.
[0039] In addition, the power conversion module of this application embodiment is 220V AC to 24V DC, and supports backup battery power supply after power failure.
[0040] Furthermore, the programmable control unit includes a PLC industrial control board and a control program, wherein the control program is equipped with an adaptive algorithm.
[0041] Furthermore, the relay unit is a multi-channel opto-isolated relay.
[0042] The relay unit in this application embodiment can be a multi-channel opto-isolated relay, which drives an intelligent solenoid valve group, a start / stop button, and an alarm device through an input / output 24V relay group with opto-coupling.
[0043] Furthermore, it also includes an alarm device connected to the smart controller 15, which alarms when a leak is detected in the water supply pipeline network.
[0044] The intelligent water supply and control leakage detection device 10 in this application embodiment also includes an alarm device, which can alarm when a leak is detected in the water supply pipeline network 11, so as to notify the user of the leak in a timely manner, reduce water waste and unnecessary economic losses.
[0045] Furthermore, the alarm device includes at least one acoustic alarm unit and an optical alarm unit.
[0046] Specifically, such as Figure 2 As shown, the intelligent water supply and control leakage detection device in this application embodiment includes: a water supply pipeline network, an intelligent solenoid valve group, a central controller, a human body detection sensor, and a distributed leakage monitoring network.
[0047] The water supply pipeline network consists of water pipes, water meters, main inlet valves, and water terminals.
[0048] The intelligent solenoid valve assembly uses a bistable 24V DC solenoid valve, installed downstream of the main water inlet valve, to ensure that the water supply to the entire water supply system can be quickly cut off when the leakage detection sensor detects a leak.
[0049] The intelligent controller integrates the following modules: a power conversion module that converts 220V AC to 24V DC, supporting backup battery power after power failure; a programmable control unit, including a PLC industrial control board and control program, equipped with an adaptive algorithm to analyze sensor data in real time and generate control commands; and a multi-channel opto-isolated relay, including a group of 24V input / output relays with optocouplers, a drive solenoid valve (i.e., an intelligent solenoid valve group), start / stop buttons, and linkage alarm devices. The intelligent controller is connected to the solenoid valves, the distributed water leakage monitoring network, and the human body detection sensor, respectively.
[0050] Human body detection sensors can be photoelectric diffuse reflection sensors, used to detect the presence of a human body in order to control the locking and unlocking of solenoid valves.
[0051] The distributed leak monitoring network includes multiple leak detection sensors, consisting of pressure sensors, humidity sensors, and acoustic detection units. One group is deployed every 0.8 meters along the pipeline, which is a multi-point deployment method. It collects water pressure fluctuations, humidity changes, and abnormal vibration signals of the pipeline in real time. Among them, the acoustic detection unit of the leak monitoring network uses frequency domain analysis to identify abnormal sound patterns in the pipeline from 20Hz to 2kHz, distinguishing between normal water use and leakage.
[0052] In the intelligent water supply and leakage detection device of this application embodiment, the intelligent controller controls the on / off state of the solenoid valve through a preset program. For example, when a human body is in the detection area of the human body sensor, the solenoid valve is locked in the energized state, allowing water to flow out. When the human body leaves the sensor detection area for more than a preset time (such as 5 seconds), the solenoid valve automatically de-energizes and closes, cutting off the water supply, thus achieving automatic water supply cut-off when no one is using water. When the leakage detection sensor detects a leak, the intelligent controller immediately cuts off the power supply to the solenoid valve, putting the solenoid valve in the open state, stopping the water supply, and activating multiple alarms (local sound and light + remote APP push), issuing a leakage alarm signal through the alarm indicator light or alarm, so as to immediately cut off the water supply and issue an alarm signal when a leak is detected.
[0053] The principle of the intelligent water supply control and leakage detection device in this application embodiment is as follows:
[0054] 1. After pressing the start button, the solenoid valve will remain energized and open as long as there is no leakage. In this state, the human body detection sensor will not function, and the water supply will continue as normal, with water flowing continuously when the faucet is turned on. When an elderly person or child is home alone, the stop button can be pressed. At this time, the solenoid valve will be de-energized, and no water will flow even if the faucet is open, as long as the person is not within the human body detection sensor area. When a person enters the human body detection sensor area, the solenoid valve will be energized and locked, allowing water to flow continuously when the faucet is turned on. If the faucet is left on, the solenoid valve will automatically de-energize and close 5 seconds after the person leaves the human body detection sensor area, automatically cutting off the water supply.
[0055] 2. In the event of a leak, the power supply to the solenoid valve will be cut off, putting the solenoid valve in the off state, stopping the water supply, and triggering a leak alarm. The solenoid valve will remain de-energized until the leak is resolved. The intelligent solenoid valve assembly is installed after the output of the main water valve, close to the main water valve, ensuring no water flows from the pipe. Pressing the stop button will deactivate the leak alarm. If the leak persists, the alarm will sound again. Specifically, if... Figure 3 As shown, the water leakage detection device obtains power through a power connection and may send the water leakage detection signal to the FX2N module (i.e., the specific type in the PLC mentioned above). The FX2N module controls the on / off state of the optocoupler-isolated relay through its output pins (YO, Y1, Y2), thereby realizing the control of the intelligent solenoid valve group.
[0056] The intelligent water supply control and leakage detection device of this application embodiment is mainly applicable to household water supply. It can supply water normally under normal circumstances, and can cut off the water supply and promptly alarm when the user forgets to turn off the tap for a period of time. When a leak occurs, it can detect it in time, cut off the water supply and alarm in time. It integrates water-saving, safety and early warning functions, and is especially convenient for empty nest elderly families and families with children. It can help users reduce unnecessary economic losses.
[0057] According to the embodiments of this application, the water supply control and leakage detection device sets up an intelligent solenoid valve group and a distributed leakage monitoring network on the water supply pipeline network, and sets up human body detection sensors around the water supply pipeline network. The intelligent controller controls the opening and closing of the intelligent solenoid valve group through at least one of the detection signals from the human body detection sensors and the leakage detection signals from the distributed leakage monitoring network, so as to realize timely detection of leakage and timely cut-off of water source, realize intelligent and automated management of water supply, effectively prevent water waste and avoid potential safety hazards.
