Description

TECHNICAL FIELD

[0001] The utility model relates to intelligent water management technical field, concretely relates to a kind of intelligent water control device. BACKGROUND

[0002] In prior art, water control equipment generally adopts traditional user identity verification method, such as password input, magnetic card reading and the like. These traditional methods have many inconveniences and limitations in practical application. First, password input needs user to remember complex password sequence, and manually input each time, which is not only cumbersome, but also prone to verification failure due to memory failure, affecting user experience. Secondly, although magnetic card reading simplifies the operation to some extent, it still requires user to carry specific card, which increases physical burden, and the card is easy to lose or damage. Once lost, user will not be able to use water control equipment, and the security and convenience are limited. In addition, whether password input or magnetic card reading, security risks caused by human factors cannot be avoided, such as password being spied or magnetic card being copied, thereby reducing the security of the system.

[0003] Currently, with the popularity of mobile payment and Internet of Things technology, users are more and more inclined to use more convenient and secure identity verification method. However, the existing water control machines on the market mostly adopt the mode of providing static two-dimensional code for users to scan. Although this mode simplifies the operation of the equipment and reduces the demand for additional hardware, it is prone to copying and theft due to the difficulty in changing the static two-dimensional code, resulting in security problems. Secondly, the use of static two-dimensional code may exist that the smart device needs to communicate with the cloud platform after scanning the code, submit consumption application to the cloud platform, and then issue consumption instruction to the control unit through the cloud platform. After the control unit feeds back the consumption situation, the cloud platform sends the consumption result to the smart device. The existence of multiple information transfer links greatly affects the recognition and response speed, and the use of static two-dimensional code often accompanies the process of manual scanning, which may take some time, especially in poor light or when the two-dimensional code is damaged.

[0004] Therefore, there is an urgent need for a more efficient, convenient and secure intelligent water control device in the prior art to solve the problems of cumbersome, inconvenient and low security of user identity verification. UTILITY MODEL CONTENT

The metering data can also be uploaded to a cloud platform, providing users with water usage statistics and analysis functions.

[0058] The operation process of the intelligent water control device is as follows: The user logs into the relevant software through a smart device, such as a mobile phone, retrieves a QR code, and points the phone screen towards the camera component 4. The camera component 4 captures and obtains the QR code information and transmits it to the decoding component. The decoding component converts the QR code information into text data and sends it to the control unit. The control unit then initiates a consumption request to the cloud platform. After receiving the consumption request, the cloud platform obtains the user's water usage permissions and billing information, issues a consumption command to the control unit, and simultaneously notifies the user of the consumption status on their mobile phone. The control unit sends an opening command to the valve unit according to the consumption command. The valve unit opens the water source according to the command and monitors the water consumption in real time through a water metering sensor. When the user stops using water or reaches the set water consumption level, the control unit sends a closing command to the valve unit, and the valve unit closes the water source, completing one water usage operation. This significantly improves the reading response speed compared to traditional static QR codes.

[0059] Through the above operating process, the intelligent water control device can realize intelligent control of water sources, meet users' precise water needs, and has functions such as remote monitoring, data storage and multiple authentication methods, which significantly improves the intelligence level of the device and the user experience.
