DETAILED DESCRIPTION

[0025] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] In order to avoid the phenomenon that staff spend a lot of time borrowing keys before going to the station, which affects work efficiency, see Figures 1 to 6 , an embodiment of the present invention provides a multifunctional door lock system, which includes: a ZigBee gateway 1, an unlocking device and a power supply unit.

[0027] Usually the base station is equipped with a power FSU (Field Supervision Unit). Based on this, the ZigBee gateway 1 uses the power FSU of the base station to wirelessly connect to the base station operation platform 2 on the remote side. Figure 2The ZigBee gateway 1 includes: a ZigBee coordinator 11, a controller 12 and an antenna. The controller 12 is connected to the ZigBee coordinator 11 through a serial port to exchange data with the unlocking device, and is also connected to the antenna to exchange data with the base station operating platform 2. The antenna can be an antenna based on mobile communication technology, such as a 3G antenna, a 4G antenna 13 and a 5G antenna. The type of the controller 12 can be CORTEX-A8, the model is AM335X, and the model of the ZigBee coordinator 11 can be EM357.

[0028] The unlocking device includes: a ZigBee module 3 and a door lock control unit. The ZigBee module 3 is connected to the ZigBee gateway 1, and the door lock control unit is used to unlock the door lock of the base station under the control of the first unlocking instruction. The first unlocking instruction is generated by the base station operation platform 2 after receiving the unlocking request, and then sent to the ZigBee gateway 1, and the ZigBee gateway 1 is forwarded to the ZigBee module 3, and then transmitted to the door lock control unit. The unlocking request is issued by the user through a dialogue with the base station operation platform 2. The unlocking request includes the base station ID and the door lock ID. For example, the user is a maintenance personnel. When he arrives at the base station, he contacts the base station manager located on the base station operation platform side by calling, and tells the base station manager the base station ID and the door lock ID. The base station manager sends the corresponding first unlocking instruction through the base station operation platform 2. In other embodiments, the base station operation platform 2 can identify the unlocking request said by the maintenance personnel, and then directly send the corresponding first unlocking request. The door lock control unit includes: a door lock control center 4 and a drive motor 5. The door lock control center 4 is used to verify the first unlocking instruction, determine the correctness and completeness of the data contained therein, and then compare whether the base station code and the lock code are consistent. If they are consistent, it is determined that the instruction is correct, and then the drive motor 5 is controlled to execute the unlocking and door opening action to achieve the remote door opening effect of the base station operation platform 2. When applied, there is a gear-shaped buckle structure on the outer ring of the key lock cylinder of the door lock, and the door is opened by driving the buckle structure by the drive motor 5. The model of the door lock control center 4 can be STM32L431, and its sleep current is <6.0uA, which is beneficial to reduce energy consumption requirements and extend battery life when the power supply unit is a battery. The unlocking method corresponding to this instruction is the ZigBee remote unlocking method. The model of the ZigBee module 3 can be EM357. The structural schematic diagram of the ZigBee module 3 is shown as follows. Figure 3 shown.

[0029] There are many types of people who perform local operations on the base station. In addition to the aforementioned maintenance personnel, who can be called the first user, there will also be base station managers, who can be called the second user. For this reason, the present invention also includes: a Bluetooth module 6, which is connected to the first portable terminal 7 via Bluetooth technology, and receives a second unlocking instruction issued by the APP on the first portable terminal 7, and the second unlocking instruction is used to control the door lock control unit to unlock the door lock. The first portable terminal 7 is held by the second user, which can be a smart phone, a tablet computer or a notebook. Specifically, the door lock control unit 4 is used to verify the second unlocking instruction, determine the correctness and completeness of the data contained therein, and then compare whether the base station code and the lock code are consistent. If they are consistent, it is determined that the instruction is correct, and then the drive motor 4 is controlled to perform the unlocking and door opening action to achieve a local wireless door opening effect. The unlocking method corresponding to the unlocking instruction is the Bluetooth wireless unlocking method. The model of the Bluetooth module 6 can be CC2640. The structural schematic diagram of the Bluetooth module 6 is shown in Figure 4 shown.

[0030] There are many types of personnel who perform local operations on the base station. In addition to the maintenance personnel and base station management personnel mentioned above, there will also be door lock manufacturer personnel who install and debug the door lock protocol. This person can be called a third user. For this reason, the system also includes: an RS485 module 8, which is connected to the second portable terminal 9 through an RS485 wired serial port, and receives a third unlocking instruction issued by the second portable terminal 9. The third unlocking instruction is used to control the door lock control unit to unlock the door lock. The second portable terminal 9 is held by a third user, which can be a smart phone, a tablet computer or a notebook. Specifically, the door lock control center 4 is used to verify the second unlocking instruction, determine the correctness and integrity of the data contained therein, and then compare whether the base station code and the lock code are consistent. If they are consistent, it is determined that the instruction is correct, and then the drive motor 5 is controlled to perform the unlocking and door opening action to achieve the local RS485 door opening effect, which is convenient for protocol debugging. The unlocking method corresponding to the unlocking instruction is the RS485 wired serial port unlocking method. The model of RS485 module 8 can be TP8485E. The structural schematic diagram of RS485 module 8 is shown in Figure 5 shown.

[0031] The system also includes: a key 10, which matches the door lock. When the key is inserted into the key lock cylinder 21 of the door lock and turned, the door lock can be unlocked. This unlocking method is a physical key unlocking method, which is suitable for base station managers to bring keys to the station or maintenance personnel to borrow keys to the station, etc., and is used to realize physical unlocking on the local base station side.

[0032] In order to facilitate the installation and maintenance of the system, the power supply unit is a battery, such as a lithium battery 22, which can be a 3.6V lithium battery. Since it is powered by a battery, after the battery has been used for a period of time, its voltage will drop and may not be able to meet the power required for the normal operation of the system. In order to prevent the battery from affecting the normal operation of the system, the system also includes: a battery voltage detection circuit 24, which is used to detect the current voltage and remaining power of the battery. The door lock control center 4 is used to generate a low voltage alarm message when the remaining power is lower than the preset power threshold, and send the low voltage alarm message to the base station operating platform 2 through the ZigBee module 3 and the ZigBee gateway 1 in sequence. The base station operating platform 2 displays the low voltage alarm message and saves it, and then notifies the maintenance personnel to go to the station to replace the battery. The structural diagram of the battery voltage detection circuit 24 is shown in Figure 6 shown.

[0033] In order to realize real-time monitoring of the door lock of the base station, the system also includes: a sensing module 25, which is used to sense the current switch state of the door lock, such as the door opening state or the door closing state. The door lock control center 4 of the door lock control unit is connected to the sensing module 25, and is used to send the current door lock state to the base station operation platform 2 through the ZigBee module 3 and the ZigBee gateway 1 in sequence when the state of the door lock changes. The base station operation platform 2 can display and save the current switch state of the door lock. The sensing module can be a door magnetic switch. When applied, a magnet is installed at the fixed position of the door frame, and a door magnetic sensor is provided in the door lock. When closing the door, the magnet attracts the door magnetic sensor. Therefore, when the magnet attracts the door magnetic sensor, it indicates that the current switch state is the door closing state; when opening the door, the magnet does not attract the door magnetic sensor. Therefore, when the magnet does not attract the door magnetic sensor, it indicates that the current switch state is the door opening state.

[0034] Sometimes the door lock of the base station may be forced to open due to external factors, such as illegal intrusion. In order to further monitor the door lock, the door lock control center 4 of the door lock control unit of the present system is also used to determine whether the current door lock state is an open state. If it is determined to be yes, that is, the door lock state is switched from a closed state to an open state, then the unlocking instruction for changing the door lock state to an open state is searched. If found, the unlocking method corresponding to the unlocking instruction is sent to the base station operation platform 2 through the ZigBee module 3 and the ZigBee gateway 1 in sequence. Otherwise, an alarm message is generated, and the unlocking alarm message is sent to the base station operation platform 2 through the ZigBee module 3 and the ZigBee gateway 1 in sequence. The base station operation platform 2 can notify the base station management personnel that the door lock is damaged and take the next step.

[0035] In order to improve the battery life of the system, the unlocking device has a low power consumption mode and a wake-up mode. In the low power consumption mode, the ZigBee module 3 and the Bluetooth module 6 do not work. At this time, the radio frequency circuits of the ZigBee module 3 and the Bluetooth module 6 are turned off to make each module reach the lowest power consumption. At the same time, the wireless data of the ZigBee gateway 1 and the first portable terminal 7 cannot be received. In the wake-up mode, the ZigBee module 3 and the Bluetooth module 6 work. At this time, the radio frequency circuits of the ZigBee module 3 and the Bluetooth module 6 are turned on, and the wireless data of the ZigBee gateway 1 and the first portable terminal 7 can also be received. The switching between the two modes can be triggered by pressing the operation button 23 or changing the door lock state.

[0036] The multifunctional locking system further includes: a status indicating unit, which is used for human-computer interaction and can indicate the operating status of the unlocking device, such as indicating the current device working status (or awake mode) / sleep (or low power mode) of the unlocking device. The status indicating unit can be an LED indicator 26.

[0037] A multifunctional locking system provided by an embodiment of the present invention has low power consumption and ultra-long battery life, can support multiple unlocking methods adapted to multiple scenarios, and can implement changes in door lock status and current door opening methods to ensure safety and practicality, facilitate the platform to record and count the number and methods of unlocking, and can effectively avoid illegal intrusions and manual prying alarms.

[0038] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
