[0026] Example 1

[0027] This embodiment provides a water management system. Figure 1 As shown, the water management system includes multiple smart faucets, multiple pressure sensors, a non-polarity two-bus, a regional controller and a system host. When the temporary water system at the construction site is being constructed, the water management system can be deployed at the same time.

[0028] The water management system is described in detail below.

[0029] In some embodiments, multiple smart faucets are installed at water use points in the water supply network, PVC conduits are laid along the water supply network and non-polar two-buses are laid, multiple pressure sensors are segmented and arranged on the water supply network, and a "hand-in-hand" wiring method is adopted between the smart faucets and the pressure sensors, and the smart faucets and pressure sensors are finally connected to the system host through the non-polar two-bus. The system host can display the opening, closing and alarm status of all smart faucets in the water supply network for precise monitoring and control. At the same time, the two-bus wiring method is adopted to simplify the installation process, facilitate debugging, and reduce maintenance costs. At the same time, the system operates under the safe voltage of DC24V, ensuring the electrical safety of the construction site.

[0030] In other embodiments, when the project is large or independently dispersed, multiple regional controllers can be added to the system. The water supply network is divided into multiple areas according to the actual water demand of the project. Each area is equipped with a regional controller. The smart faucets and pressure sensors in the area are connected to the regional controller in the area through a non-polarity two-bus. Multiple regional controllers are connected to the system switchboard through CAN communication lines. Each regional controller can display the opening, closing and alarm status of all smart faucets in the area, conduct precise monitoring and control, and collect information and feedback to the system host.

[0031] In other embodiments, the system host has a reserved communication interface that can be connected to the network system of the smart construction site to achieve remote monitoring and management of data.

[0032] As a specific implementation of smart faucets, smart faucets have independent address coding, which enables the regional controller or system host to accurately monitor the status of each faucet. Smart faucets have two working modes: automatic sensing and manual control. Smart faucets use the automatic sensing working mode by default. When people start using them, they can be opened manually first. If the user forgets to turn off the faucet when leaving, the system will automatically sound an alarm and turn off the faucet to eliminate water waste and potential risks. If the user needs continuous water supply, he can switch to manual control working mode or set the time for automatic shutdown.

[0033] As a specific implementation of the pressure sensor, the pressure sensor can monitor the water pressure changes in the water supply network in real time. At night or non-working hours, when all faucets are shown to be closed and the pressure drop detected by the system exceeds the normal range, the zone controller and the system host will automatically alarm to remind the on-duty personnel of possible pipe network leakage problems, so as to promptly discover and resolve potential risks.

[0034] Example 2

[0035] This embodiment provides a smart faucet, which is used in the water management system in embodiment 1. Figure 2 and Figure 3 As shown, the smart faucet includes a faucet body and a module box. The module box is mounted on the water pipe behind the faucet body. A sensing device, an alarm, a control module and a solenoid valve are arranged in the module box. The sensing device, the alarm and the solenoid valve are all connected to the control module. The sensing device includes an infrared sensor and a water flow sensor. The infrared sensor is used to sense whether there are people within a certain range around the faucet. The sensing range of the infrared sensor can be 1 meter. The water flow sensor is used to detect the duration of water flow when there are no people within a certain range of the faucet. The control module is used to control the alarm to sound and the solenoid valve to close. The alarm is used to sound an alarm to remind people who use water, and the solenoid valve is used to cut off the water flow of the faucet.

[0036] In some embodiments, see Figure 4 As shown, the outside of the module box is also provided with a display screen, a manual mode button, an automatic mode button and other function buttons. The display screen is connected to the sensor and is used to display the automatic closing time of the faucet. Both the manual mode button and the automatic mode button are connected to the control module and are used to switch the faucet between automatic sensing and manual control working modes. Other function buttons include an increase button and a decrease button for setting the automatic closing time, a confirmation button and a reset button. The confirmation button is used to confirm after adjusting the automatic closing time, and the reset button is used to reset the automatic closing time. The automatic closing time is in seconds by default, and a long press switches to minutes or hours. When long pressed, the display screen will show the measurement unit of the current stage.

[0037] Specifically, the faucet is usually in automatic sensing mode. If the user does not close the faucet in time after use, the infrared sensor in the sensing device detects that there is no person within a certain range near the faucet and the water flow sensor detects the continuous existence of water flow. When the continuous existence time of the water flow reaches the delayed closing time set by the control module, the control module controls the alarm to automatically sound an alarm and force the electromagnetic valve to close to cut off the water supply to the faucet. The default delay time set by the control module is 15s, and the delay time can be adjusted according to actual needs through the increase and decrease buttons in the function buttons. This automatic sensing design not only avoids the waste of water resources, but also reduces the damage to facilities that may be caused by long-term water flow.

[0038] In order to meet different construction needs, such as long-term water use or other specific operations, users can switch to manual control mode to ensure water supply. At the same time, the automatic closing time of the faucet can be set according to water demand. In this way, even without supervision, the effective use of water resources can be guaranteed.

[0039] Those skilled in the art should understand that the present invention can be implemented in many other specific forms without departing from the spirit and scope of the present invention. Based on the embodiments of the present invention, any changes and modifications made by ordinary technicians in the field of the present invention according to the above disclosure are within the scope of protection of the claims.
