It is used to collect the current location information of the water dispenser and report it to the host computer in real time by the main board 1.

[0034] The following section will describe in detail the installation and application principles of each component and the controller electronics.

[0035] 1. Motherboard 1 The motherboard 1 is directly fixed inside the housing using screws and other fasteners. Connections to other electronic devices are primarily via electrical connections, achieved through ribbon cables and interfaces. For example, it is electrically connected to the LCD screen 6, the cavity speaker 3, the NFC card reader module, the valve control button 5, the indicator light 8, the Bluetooth module, the NB module, and the GPS module via corresponding interfaces and ribbon cables to achieve data transmission and signal control.

[0036] The mainboard 1 is located inside the casing and is the core component of the entire water dispenser controller. It is usually located in a relatively stable position inside the casing that is easy to connect with other components, so as to ensure smooth wiring connections between the components.

[0037] Motherboard 1 can be, for example, an M-100 model motherboard, which has a high-performance processor, abundant interface resources and a stable power supply system, and can meet the various functional requirements of the water dispenser controller.

[0038] The motherboard, as the core of the entire system, has a processor responsible for handling various input signals and executing corresponding programs. It receives data from various modules through interfaces, such as display data from the LCD screen and interactive information from the NFC card reader module, processes it according to preset programs, and then sends the processing results to the appropriate devices, such as controlling the LCD screen display or triggering the cavity speaker alarm. This allows for the organic integration of various functional modules, improving system stability and reliability. Furthermore, the abundant interface resources facilitate expansion and upgrades, allowing for the addition or replacement of other functional modules according to different needs.

[0039] 2. LCD screen 6 The LCD screen 6 is fixed to the motherboard 1 using brackets and screws, and the electrical connection is made via a ribbon cable to the display interface of the motherboard 1. The ribbon cable ensures stable signal transmission, enabling the LCD screen to accurately display the information sent by the motherboard. The LCD screen 6 is located above the motherboard 1 and is fixed and displays information through the mounting window 9 in the upper area of ​​the cover glass 7. This positioning design allows users to directly observe water intake information.

[0040] For example, the L-200 model LCD screen is used, which has high resolution, high contrast and good viewing angle, and can clearly display various water intake information.

[0041] The LCD screen controls the transmission and blocking of light by changing the arrangement of liquid crystal molecules, thus displaying images. The motherboard 1 sends water usage information (such as cumulative water usage, usage time, total price, card balance, and water dispenser status) to the LCD screen's driver chip in the form of digital signals. The driver chip controls the arrangement of liquid crystal molecules based on these signals, thereby displaying the corresponding text and numbers. This intuitive display of water usage information allows users to easily monitor their water usage in real time. High resolution and a good viewing angle ensure clear display under different lighting conditions and viewing angles.

[0042] 3. Cavity speaker 3 The cavity speaker 3 is fixed inside the housing with screws, and the electrical connection is made to the audio output interface of the motherboard 1 via an audio cable. The audio cable transmits the audio signal output from the motherboard 1 to the cavity speaker, enabling it to produce sound. The cavity speaker 3 is located inside the housing near the sound output port 10 of the front cover 4, allowing the sound to be propagated more effectively to the outside. An S-300 model cavity speaker can be used, which features high sound quality, high volume, and good bass performance, enabling clear system alarm announcements.

[0043] The mainboard 1 sends the alarm signal as an audio electrical signal to the drive circuit of the cavity speaker. The drive circuit controls the diaphragm of the speaker to vibrate according to the change of the electrical signal, thereby generating sound. The sound is transmitted to the outside through the sound output port on the front shell 4. It can promptly and clearly broadcast system alarms to remind users of abnormal conditions of the water dispenser. High sound quality and high volume ensure that the alarm sound can be clearly heard by the user.

[0044] 4. Cover glass 7 The cover glass 7 is secured to the window of the housing using sealing strips and clips, ensuring a tight fit and preventing dust and moisture from entering. The NFC card reader module is electrically connected to the mainboard 1 via a ribbon cable, and the barcode label is directly affixed to the surface of the cover glass 7.

[0045] The cover glass 7 covers the front window of the housing, and the barcode label and NFC card reader module are located in a position that is easy for the user to operate. The mounting window 9 is located in the upper area to fix the LCD screen 6.

[0046] The cover glass 7 can be, for example, the G-400 model, which features high transparency, high strength, and good abrasion resistance. The NFC card reader module uses the N-500 model, which features high sensitivity and fast response.

[0047] The barcode label provides a QR code for water dispensing. After the user scans the QR code with their mobile phone, the information is sent to the host computer via the network. The host computer then sends relevant instructions to the motherboard 1. The NFC card reader module interacts with the user's NFC card through electromagnetic induction, reads the information on the card, and sends the interaction information back to the motherboard 1.

[0048] The highly transparent cover glass does not affect the LCD screen's display quality while protecting internal components from external damage. The inclusion of a barcode label and NFC card reader provides diverse water dispensing options for user convenience.

[0049] 5. Valve control button 5 The valve control button 5 is installed in the mounting hole of the front housing 4 via a button base and screws. The electrical connection is made via a wire to the input interface of the main board 1. The wire transmits the signal of the button being pressed or released to the main board 1. The valve control button 5 is located on the front housing 4, in a convenient position for user operation. Users can directly press the button to control the opening and closing of the valve.

[0050] Valve control button 5 can be selected from models such as B-600, which has a good feel and durability.

[0051] When the user presses the valve control button, the internal contacts of the button close, generating an electrical signal. This signal is transmitted to the main board 1 via a wire. The main board 1 then controls the valve to open or close based on the received signal.

[0052] Therefore, the operation is simple and intuitive, and users can control the valve opening and closing at any time as needed, which improves the flexibility of water intake.

[0053] 6. Rear shell 2 and front shell 4 The rear shell 2 and the front shell 4 are connected by screws or clips to ensure the airtightness and stability of the shell. The power interface 12 and signal interface 11 on the rear shell 2 are used to connect to external power sources and other devices.

[0054] The rear shell 2 is located at the rear of the entire water dispenser controller, and the front shell 4 is located at the front. Together, they form a housing to protect the internal electronic equipment.

[0055] The rear shell 2 and the front shell 4 are made of plastic, which has good strength and corrosion resistance.

[0056] The power interface 12 on the rear shell 2 introduces external power to the motherboard 1, providing power support for the entire system. The signal interface 11 is used for data transmission and communication with other devices, such as connecting to a host computer. The plastic shell is lightweight, low-cost, and has good insulation and corrosion resistance. The combined design of the rear and front shells facilitates the installation and maintenance of internal electronic equipment.

[0057] 7. Indicator light 8 Indicator light 8 is fixed to the cover glass 7 through mounting holes, and the electrical connection is made to the output interface of the main board 1 via a wire. The wire transmits the control signals from the main board 1 to the indicator light, controlling its on / off state.

[0058] Indicator light 8 is located on the cover glass 7, in a prominent position for easy observation by the user. The main board 1 sends control signals based on the system's operating status. When a system malfunction occurs, the main board 1 sends a signal to illuminate the indicator light, causing it to light up as an alarm indication. The on / off status of the indicator light visually indicates the system's operating status, allowing users to promptly detect abnormalities.

[0059] 8. Bluetooth module The Bluetooth module is integrated into the housing and connected to the Bluetooth interface of motherboard 1 via a ribbon cable. The ribbon cable enables data transmission and communication control between the Bluetooth module and motherboard 1.

[0060] The Bluetooth module is located inside the housing, close to the motherboard 1, to reduce signal transmission distance and interference. A Bluetooth module such as the BT-900 can be used, which features high transmission rates and stable connection performance.

[0061] The Bluetooth module communicates wirelessly with the host computer via the Bluetooth protocol. Motherboard 1 sends the data to be transmitted to the Bluetooth module, which then transmits the data to the host computer as Bluetooth signals. Simultaneously, the Bluetooth module receives instructions from the host computer and transmits them back to motherboard 1.

[0062] Bluetooth communication is wireless and convenient, facilitating short-range data transmission and communication control between the water dispenser controller and the host computer.

[0063] 9. NB Module Specific connection method: The NB module is integrated and installed inside the housing, and connected to the NB interface of motherboard 1 via a ribbon cable. The ribbon cable ensures a stable connection and data transmission between the NB module and motherboard 1.

[0064] The NB module is located inside the housing, adjacent to the Bluetooth module, facilitating unified management and wiring. The NB-1000 model NB module can be selected, featuring low power consumption and wide coverage.

[0065] The NB module is based on NB-IoT (Narrowband Internet of Things) technology and communicates remotely with the host computer via the operator's base station. Motherboard 1 sends data to the NB module, which then transmits the data to the host computer via the base station. Simultaneously, it receives instructions from the host computer and transmits them back to Motherboard 1.

[0066] The Bluetooth module and the NB module are independently connected to the Bluetooth interface and NB interface of the motherboard 1, respectively, and both operate in parallel. They are installed side by side in the housing for easy connection and management with the motherboard 1.

[0067] When Bluetooth communication is normal, motherboard 1 transmits data and performs communication control with the host computer via the Bluetooth module. When Bluetooth communication fails or exceeds the Bluetooth communication range, motherboard 1 automatically switches to the NB module for communication, ensuring continuous data transmission. This redundant communication structure improves the system's reliability and stability; even if one communication method fails, the other can still guarantee normal data transmission.

[0068] 11. GPS module The GPS module is integrated into the housing and connected to the GPS interface on the motherboard 1 via a ribbon cable. The ribbon cable enables data transmission between the GPS module and the motherboard 1.

[0069] The GPS module is located inside the housing, ideally close to the top of the housing, to achieve better satellite signal reception. For example, the G-1100 model GPS module can be used, which features high accuracy and fast positioning capabilities.

[0070] The GPS module receives satellite signals, calculates the current geographical location of the water dispenser, and sends the location information to the mainboard 1 in the form of a digital signal. The mainboard 1 then reports the location information to the host computer in real time. This high-precision positioning function can accurately obtain the location information of the water dispenser in real time, facilitating remote management and monitoring by the host computer.

[0071] The controller can be installed on the water dispenser, and its usage is as follows: 1. Water hose Unscrew the hose cap and connect the hose to the water inlet.
