[0032] The embodiment of the present invention converts energy and generates electricity based on the mechanical energy when the door body 1 rotates, and performs trigger-type power supply based on the trigger switch. Only the electrical energy for the first use needs to be provided, and the mechanical energy during each door opening can provide sufficient electrical energy for subsequent identity authentication and unlocking, realizing the energy closed-loop of power generation and power consumption of the access control system, eliminating the need for mains wiring or external power supply, reducing the installation cost and usage cost, and improving the security of the access control system.

[0033] Refer to Figure 4 , further as an optional implementation manner, a processor and an electric control door lock are installed in the door lock device 20. The identity recognition module and the electric control door lock are both electrically connected to the processor.

[0034] Specifically, the processor is used to perform authentication and recognition based on the identity information obtained by the identity recognition module. When the authentication is passed, the electric control door lock is opened so that the door body 1 can be opened.

[0035] Refer to Figure 3 and 4 , further as an optional implementation manner, the identity recognition module includes at least one of a fingerprint recognition module 202 and an RFID recognition module 201.

[0036] Refer toFigure 4 Further as an optional implementation, a switch circuit is also installed in the access control device. The trigger switch is electrically connected to the switch circuit. The switch circuit is a circuit that remains powered on for a certain number of seconds after being triggered by the trigger switch. The power supply terminals of the processor and the electric control door lock are both electrically connected to the switch circuit, and the switch circuit is electrically connected to the power generation device 28.

[0037] Specifically, the trigger end of the trigger switch is in contact with the identity recognition module. When the user performs identity recognition (pressing the fingerprint, swiping the RFID card), the trigger switch can be triggered, and then the switch circuit is powered on, so as to provide electrical energy for the processor and the electric control door lock for a certain period of time for identity authentication and access control unlocking.

[0038] Refer to Figure 4 Further as an optional implementation, a charging circuit and a storage battery are installed in the power generation device 28. The generator 27 is electrically connected to the storage battery through the charging circuit, and the storage battery is electrically connected to the switch circuit.

[0039] Specifically, the storage battery is used to store the electrical energy generated by the generator 27. When the switch circuit is triggered, the storage battery supplies power to the processor and the electric control door lock through the switch circuit.

[0040] Refer to Figure 4 Further as an optional implementation, a voltage monitoring module is also installed in the power generation device 28, and the storage battery is also electrically connected to the processor through the voltage monitoring module.

[0041] Specifically, the voltage detection module is used to monitor the power of the storage battery (reflected by the voltage). When the power of the storage battery is insufficient, it can be reported to the staff through the processor.

[0042] Refer to Figure 3 and 4 Further as an optional implementation, an emergency contact 203 is also embedded on the door lock device 20, and the emergency contact 203 is electrically connected to the charging circuit.

[0043] Specifically, when the power of the storage battery is insufficient, the storage battery can be manually charged through the emergency contact 203 and the charging circuit.

[0044] Refer to Figure 4 Further as an optional implementation, a wireless transmission module is also installed in the door lock device 20. The wireless transmission module is electrically connected to the processor. The wireless transmission module is used to communicate with the server through the upper computer. The access control system further includes a user terminal, and the user terminal is communicatively connected to the server.

[0045] Specifically, when the identity authentication is successful, the door opening information can be generated by the processor and uploaded to the server through the wireless transmission module and the upper computer. The user terminal can download the door opening information of the access control system from the server.

[0046] The system structure of the embodiment of the present invention is described above. The working principle of the embodiment of the present invention is described in detail below.

[0047] During operation, the user presses the fingerprint recognition module to trigger the trigger switch, and the trigger switch operation triggers the switch circuit to turn on the battery (with a certain initial charge), and then the processor and other electrical components are powered through the switch circuit; when the user is identified by fingerprint recognition or by the RFID recognition module, the processor controls the electric door lock to unlock, and then the user pushes the door body to open the door body, and at the same time, the processor sends the door opening signal to the host computer through the wireless transmission module, and the host computer uploads the switch information to the server for subsequent reference; when the user opens the door body, the rotation of the door body drives the movement of the rotating shaft, and the movement of the rotating shaft drives the movement of the hollow tube, and then the movement of the hollow tube drives the energy supply cylinder to rotate on the rotating seat. At the same time, the movement of the hollow tube drives the movement of the hollow piston, and then the gas in the energy supply cylinder is pushed to the connecting pipe through the No. 2 one-way valve, and then the air enters the energy storage cylinder through the connecting pipe. Under the action of the No. 2 one-way valve, the gas can only enter the energy storage cylinder. In the cylinder, air enters the energy storage cylinder and pushes the energy storage piston up, and then the energy storage piston rises to store energy under the action of the counterweight. At the same time, under the action of the air pressure in the energy storage cylinder, the air in the energy storage cylinder is discharged downward through the capillary tube. The diameter of the capillary tube is small, and the gas is slowly released through the capillary tube. After the gas is discharged from the capillary tube, it pushes the generator fan to move. The rotation of the generator fan drives the generator to work, and then the generator works to charge the battery through the charging circuit. After the battery is charged, it supplies energy through the switching circuit; the voltage monitoring module monitors the battery voltage, wherein the voltage monitoring module has a backup power supply. The backup power supply directly powers the processor when the battery voltage is too low, and then sends the voltage signal to the processor. After processing, the processor sends the information packet to the host computer through the wireless transmission module. The host computer uploads the signal to the server, and the server sends the signal to the user end. After receiving the information, the user end carries a power supply to connect the emergency contact to charge the battery.

[0048] The above describes the system structure and working principle of the access control system of the embodiment of the present invention. It can be recognized that the embodiment of the present invention performs energy conversion and power generation based on the mechanical energy of the door body when it rotates, and performs trigger-type power supply based on the trigger switch, which can provide sufficient power for subsequent identity authentication and unlocking, and realizes the energy closed loop of power generation and power consumption of the access control system. There is no need for AC wiring or external power supply, which reduces the installation cost and use cost, and improves the security of the access control system. In addition, the embodiment of the present invention is suitable for scenes such as hotels where the number of door openings and closings is high. By opening and closing the door, power can be effectively generated, and the door opening information can be effectively counted through the Internet of Things. When accidents such as theft occur, it is convenient for subsequent investigations and can effectively reduce power consumption.

[0051] 2) Uploading the door opening information to the server to realize the Internet of Things function of access control information;

[0052] 3) Charging the battery through the door opening and closing actions. Under the action of the energy storage cylinder, the instantaneous action energy of the door opening and closing can be stored, and the energy is released and then generated electricity, thereby realizing the power generation function, and the power generation amount is large, and the function of the device not being connected to an external power supply can be realized;

[0053] 4) Avoiding the problem that the door cannot be opened due to insufficient battery voltage through the voltage monitoring module and emergency contacts, with high reliability.
