Description

Technical Field

[0001] This utility model relates to the field of intelligent hinge linkage technology, and in particular to an intelligent hinge and electric door lock linkage system. Background Technology

[0002] Smart furniture represents an efficient lifestyle sought after by modern people, while intelligent access control and security management systems are a new type of modern security management system. It integrates microcomputer automatic identification technology and modern security management measures, involving numerous new technologies such as electronics, mechanics, optics, computer technology, communication technology, and biotechnology. It is suitable for various confidential departments. Existing electric hinge devices can be opened and closed by sending control signals; existing access control systems include fingerprint recognition systems, facial recognition systems, password systems, and voice recognition systems.

[0003] However, most existing access control technologies integrate human body sensing, voice modules, and fingerprint modules into smart locks. But due to the limited space in smart locks, they cannot store large-capacity batteries, resulting in short battery life. On the other hand, existing electric hinge devices cannot intelligently detect resistance, which makes the motors on the electric hinge devices easy to burn out. Summary of the Invention

[0004] Existing smart access control systems integrate most functions into the door lock, but due to the limited space of the door lock, their battery life is short, and the electric hinge mechanism has a low level of intelligence, making the motor prone to burnout.

[0005] To address the aforementioned issues, a smart hinge and electric door lock linkage system is proposed. This system integrates a control board for access control, a human detection module, a voice interaction module, and a remote control module into the smart hinge device's control board. Only the actuator is located on the electric door lock. The entire system is controlled by a controller on the control board. It uses an external power supply during operation and only switches to a battery-powered module during power outages. This solves the problem of short battery life in existing smart access control systems, which integrate most functions into the door lock but are limited by the lock's space. Furthermore, by integrating a current detection module into the control board, the system stops the door opening and closing when the motor stalls, thus preventing motor burnout.

[0050] Existing smart access control systems integrate most functions into the door lock, but due to the limited space of the door lock, their battery life is short, and the electric hinge mechanism has a low level of intelligence, making the motor prone to burnout.

[0051] To address the aforementioned issues, a smart hinge and electric door lock linkage system is proposed.

[0052] Firstly, a smart hinge and electric door lock linkage system, such as Figure 1 , Figure 1 This is a schematic diagram of the modular structure of the intelligent hinge and electric door lock linkage system in this application; it includes an intelligent hinge device and an electric door lock; the intelligent hinge device is electrically connected to the electric door lock; the intelligent hinge device includes a hinge door leaf section and a hinge door frame section; a control board and a hinge motor are arranged inside the hinge door leaf section; the hinge door leaf section and the hinge door frame section are rotatably connected through the hinge motor; the control board integrates a controller, a power management module, and a motor drive module; an external power interface is arranged on the hinge door frame section; the external power interface is electrically connected to the power management module through a hinge cable, and is used to supply power to the linkage system through the power management module; the motor drive module is electrically connected to the hinge motor; the controller is electrically connected to both the motor drive module and the electric door lock.

[0053] The controller is used to acquire various switching signals to control the linkage between the hinge motor and the electric door lock. These various switching signals include:

[0054] Human body induction switch signal, switch button switch signal, smart terminal switch signal, remote control switch signal, and voice switch signal.

[0055] In this embodiment, a control-type APP can be installed on the smart terminal to transmit switch signals. The voice switch signals include offline voice switch signals and smart voice switch signals, and can also be sent via Bluetooth.

[0056] In this embodiment, an external power interface or energy storage module is arranged in the hinge frame. This external power interface or energy storage module supplies power to the power management module on the control board via a wiring connection to the hinge, and then supplies power to the intelligent hinge device and electric door lock through the power management module. The controller obtains open or close commands through a switch button integrated on the control board, a human body detection module arranged in the hinge door leaf, a voice interaction module, or a remote control module. The controller sequentially transmits the open or close commands to the electric lock and motor drive module. When the external power supply is interrupted, the power management module obtains electrical energy from the energy storage module to supply power to the intelligent hinge device and electric door lock. During door opening and closing, the controller uses a current detection module to detect the motor current; based on the detected current value, it determines whether the motor is stalled, and controls the door to stop opening and closing if the motor is stalled. By integrating the control board for access control, the human body detection module, the voice interaction module, and the remote control module into the control board of the smart hinge device, only the actuator is arranged on the electric door lock. The entire system is controlled by the controller on the control board. It uses an external power supply when powered, and only uses the energy storage module to supply power when the power is off. This solves the problem of short battery life of existing smart access control systems that integrate most functions into the door lock but are limited by the door lock's space. By integrating a current detection module into the control board, the door opening and closing is stopped when the motor stalls, which also solves the problem of the motor being easy to burn out.

[0057] In this embodiment, the various modules of the system's intelligent function are arranged in the intelligent hinge device, which is powered by an external power supply, thus solving the problem of short battery life. Figure 2 , Figure 2 This is a schematic diagram of a specific embodiment of the intelligent hinge and electric door lock linkage system in this application; the controller outputs to the motor drive module through two output control pins (DO) to control the forward and reverse rotation of the motor. In this embodiment, the hinge motor can be a DC geared motor.

[0058] In this embodiment, the controller uses an industrial-grade 32-bit processor with a built-in watchdog timer to ensure reliable 24 / 7 operation. The motor drive module can use an AT DC motor drive dedicated chip.

[0059] In a preferred embodiment, an energy storage module is also arranged inside the hinge frame; the energy storage module is electrically connected to the power management module through the hinge wiring, and is used to supply power to the linkage system during power outages.

[0060] In this embodiment, the energy storage module can be a 12V lithium battery. Under normal circumstances, the energy storage module stores electricity through an external power source, and supplies power to the system in the event of a power outage. The 12V lithium battery can be externally mounted on the hinge frame.

[0061] In a preferred embodiment, the control board also integrates a current detection module; the current detection module is electrically connected to both the power management module and the controller, and is used to send a stall signal to the controller when the detected electrode current exceeds a specified threshold, causing the controller to stop the hinge motor. Figure 2 In this process, the motor stall current is detected, and the controller performs high-precision AD sampling. Combined with an external operational amplifier, high-precision motor drive current detection is achieved.

[0062] In a preferred embodiment, the control board also integrates a speed regulation module; the speed regulation module is electrically connected to both the power management module and the controller, and is used to regulate the motor speed. In this embodiment, as... Figure 2 The speed regulation module is connected to the DC geared motor through the wiring terminals. When adjusting the speed, the motor current can be adjusted by a variable resistor to achieve the purpose of speed regulation.

[0063] In a preferred embodiment, the control board also integrates a switch button; the switch button is electrically connected to the controller via a first control pin DI, and is used to transmit a switch signal to the controller.

[0064] like Figure 2 In this embodiment, the switch button is electrically connected to the controller via a terminal block and the first control pin DI, transmitting the received switch signal to the controller.

[0065] In this embodiment, the control board also integrates a Type-C emergency power interface; the Type-C emergency power interface is used to connect an emergency power source, which can be a 20W fast charging interface, connecting an external power source to charge the battery storage module in an emergency, and also supplying power to the smart hinge device and electric door lock.

[0066] In a preferred embodiment, the control board also integrates a human body detection module; the human body detection module is electrically connected to the controller via a second control pin DI, and is used to transmit the acquired human body signals to the controller.

[0067] like Figure 2 The human detection module can be implemented as a human detector module, electrically connected to the second control pin DI via a terminal block. The human detection module can use a 2.4G microwave human detector with adjustable sensitivity.

[0068] In a preferred embodiment, a voice interaction module and a remote control module are also arranged inside the hinge door leaf section; the voice interaction module is electrically connected to the controller through the third control pin and the fourth control pin, and is used to transmit voice control commands and output interactive voice; the remote control module is electrically connected to the controller through the fifth control pin and the sixth control pin, and is used to transmit remote control commands to the controller.

[0069] like Figure 2 The voice interaction module can be implemented as an offline voice module, electrically connected to the third control pin RX and the fourth control pin TX via terminal blocks. Multiple voice control keywords can be customized, such as "open door," "close door," "please open door," and "please close door."

[0070] The remote control module can be implemented as a 433M remote control receiver module, which is electrically connected to the controller through the fifth and sixth control pins. The 433M wireless frequency band has the characteristic of strong penetration.

[0071] This invention discloses a smart hinge and electric door lock linkage system. By integrating a control board for access control, a human body detection module, a voice interaction module, and a remote control module into the control board of the smart hinge device, only the actuator is located on the electric door lock. The entire system is controlled by a controller on the control board. It uses an external power supply during operation and only uses a battery storage module for power during power outages. This solves the problem of short battery life in existing smart access control systems, which integrate most functions into the door lock but are limited by the lock's space. Furthermore, by integrating a current detection module into the control board, the door opening and closing is stopped when the motor stalls, thus preventing motor burnout.
