The Bluetooth module uses the MS44SF11-nRF52820 Bluetooth chip as a PCBA board with integrated Bluetooth data function. The electronic parking lock is also provided with a remote control key for opening and closing the electronic parking lock separately in the event of a signal interruption. The parking space management integrated machine adopts a floor-standing foundation installation mode, and is centrally powered by a power line. The parking space management integrated machine and the parking space electronic lock are controlled and connected by a signal line, and the signal line and the power line are arranged by pre-buried or exposed wire trough threading.

The alarm information is fed back to the information processing module and sent to the parking owner's mobile phone; 7. Power module, including charging pile management (you can choose whether to add charging pile function) and equipment self-power management (including all-in-one self-power, electronic parking lock power, lighting and display module power, etc.); at the same time, in the equipment self-power mode, you can choose not to connect the power cord, use 48V lithium battery for power supply, which can maintain operation for 90 days, and the lithium battery can be charged separately; 8. Display module: LCD display module, which displays parking space information, parking space owner’s contact number, parking time, charging time, etc.; 9. Lighting module: 2-way lighting module plus 6W fill light, providing night lighting, assisting license plate recognition, controlled by the all-in-one control module; The electronic parking lock of this embodiment: 1. The lifting module is in a fixed lifting state when there is no vehicle. It is controlled by the integrated machine control module and the wireless control module. The lifting is controlled by the integrated machine signal line and the remote control key. At the same time, the lifting module status will be fed back to the integrated machine database acquisition module in time and sent to the mobile phone. When the lifting module is artificially damaged and forcibly changed, the alarm information will be fed back to the database acquisition module. At the same time, the information processing module issues a command, and the control module captures the alarm information and transmits the information; 2. The license plate recognition module automatically recognizes the license plate information of the vehicle entering the warehouse, transmits the information to the database collection and information management module of the management integrated machine, compares it with the entered license plate information, and issues a command through the control module to control the parking lock to drop or remain stationary; 3. The wireless control module is equipped with an infrared receiver to facilitate wireless control of an independent (infrared transmitter) remote control key within a short distance of 10 meters, which is convenient for emergency parking in special circumstances.

[0023] The client of this embodiment is a mobile phone APP: 1. Information reading and writing module: parking space owners can read and write parking space information through the APP, and check the parking space status in real time to see whether it is occupied; 2. Remote control module: remotely control the all-in-one machine through the mobile phone to control power output, parking lock lifting status, lighting on and off, etc.

[0024] The parking space management all-in-one machine makes parking space management more convenient. Car owners do not need to get out of the car or use a remote control to control the lifting of the parking space lock. The license plate recognition automatic parking space lock can autonomously identify the license plate and number through the license plate recognition module. In conjunction with the mobile phone APP applet, the lifting and lowering of the parking space lock can be controlled through the linkage of the control module and the lifting module. The lock is lowered when the car enters and raised when the car leaves, which greatly improves the convenience of life and basically solves the trouble of getting on and off the car. The linkage with the parking lot management system and the parking space guidance system can effectively standardize parking space management, and a unified power supply can be used instead of lithium batteries, which can reduce the trouble of annual battery charging. At the same time, it can be used as a charging pile to charge new energy vehicles; in the property joint management mode, the license plate data is entered once, and the background centrally processes the allocation of permissions to reduce the friction caused by grabbing parking spaces; each system is linked and coordinated, and parking management is in place in one step, improving management efficiency and improving car owner satisfaction.

[0025] Example 2 The difference between this embodiment and embodiment 1 is that this embodiment provides an integrated parking space management method based on the Internet of Things, including: When a vehicle enters the garage, the license plate information is collected and uploaded through the license plate recognition module of the electronic parking lock; The information is compared through the information processing module of the parking space management integrated machine. After the comparison is passed, the control module is used to control the display module to display the electronic comparison result information, and at the same time control the electronic parking space lock to open and lower. If the comparison fails, the control module controls the language module to give a voice reminder, and the alarm information is sent to the client through the alarm module.

[0026] Specifically, The license plate recognition method in this embodiment is: a high-definition license plate recognition camera and an image recognition algorithm are integrated into the electronic parking lock. The camera can use a device with high resolution, wide dynamic range and low illumination performance to ensure that the license plate image can be clearly captured under different lighting conditions (such as strong light during the day and dim light at night). The image recognition algorithm is based on the convolutional neural network (CNN) technology in deep learning, and a high-precision license plate recognition model is obtained through training with a large amount of license plate image data.

[0027] When a vehicle enters the parking space recognition area, the camera automatically captures the license plate image. The captured image data is transmitted to the processing unit in the license plate recognition module, and the image is analyzed using the trained CNN model. The model first pre-processes the image, including grayscale, noise reduction, edge detection and other operations, and then extracts the license plate area features and matches them with the license plate template in the database to accurately identify the license plate number. The identified license plate number information is uploaded to the parking space management integrated machine in real time through the wireless control module for subsequent processing.

[0028] Wireless communication method in this embodiment: The system in this embodiment adopts wireless communication technologies such as Bluetooth, ZigBee or Wi-Fi. Bluetooth technology (such as low-power Bluetooth) is used for short-range, low-power device connection, which is suitable for communication between the client (mobile phone APP applet) and the parking space management integrated machine; ZigBee technology can be used for stable communication between the parking space management integrated machine and the electronic parking space lock, which has the characteristics of low power consumption and strong self-organizing network capability; Wi-Fi technology can be used for the connection between the system and external networks (such as property backend management system, cloud server) to realize remote data transmission and management.

[0029] A Bluetooth module (such as MS44SF11 - nRF52820 Bluetooth chip), ZigBee communication module or Wi-Fi module is integrated into the parking space management machine. The electronic parking lock is equipped with a corresponding wireless communication module. The client establishes a connection with the parking space management machine through Bluetooth to realize the entry of vehicle information and the sending of remote control commands. The parking space management machine and the electronic parking lock exchange data through the ZigBee network to transmit information such as license plate recognition results and control commands (such as opening or closing the parking space lock). When data needs to be transmitted to an external network, the Wi-Fi module sends parking space usage data, alarm information, etc. to the property background management system or cloud server, and the property staff can monitor the parking space situation in real time.

[0030] The database management method in this embodiment: In this embodiment, a relational database (such as MySQL) or a non-relational database (such as MongoDB) is used to store vehicle information, parking space information, user information, etc. The database management system is responsible for data storage, retrieval, update and deletion operations, and ensures the integrity and security of the data.

[0031] In the database acquisition module of the parking space management integrated machine, the collected vehicle information (including license plate number, vehicle model, owner contact information, etc.), parking space number, user authority and other data are stored in the database. When the vehicle enters the warehouse, the information management module queries the corresponding vehicle information from the database for comparison. At the same time, the database sets up a user authority management mechanism to ensure that only authorized users (such as car owners and property management personnel) can access and modify relevant data. The database backup and recovery function can prevent data loss and ensure the reliability of the system.

[0032] The information comparison and control method in this embodiment: In the information management module of the parking space management integrated machine, the information comparison algorithm is implemented using programming technology (such as C++, Java, etc.). The algorithm matches the license plate information uploaded by the electronic parking space lock with the vehicle information stored in the database. The control module controls the opening and closing of the parking space lock and the operation of other related devices (such as display module, voice module, alarm module) through circuit control technology (such as relay control) according to the comparison result.

[0033] When the license plate recognition information is transmitted to the parking space management integrated machine, the information comparison algorithm first accurately matches the license plate number. If the match is successful and the vehicle and parking space information correspond (such as the parking space number bound to the vehicle is consistent with the current parking space), the control module sends an opening signal to the lifting module of the electronic parking space lock through the relay control circuit to lower the parking space lock. At the same time, the control display module displays a welcome message to prompt the owner to park. If the comparison is unsuccessful, the control module triggers the voice module to issue a prompt tone to inform the owner that the parking space is incorrect, and sends the abnormal information to the client (such as the owner's mobile phone APP) and the property background through the alarm module, while keeping the parking space lock closed to prevent illegal parking.

[0034] The remote control method in this embodiment: The remote control function is realized through the client (mobile phone APP applet). The APP development adopts cross-platform development technology (such as Flutter, React Native) to ensure compatibility on different operating systems (iOS, Android). The communication between the APP and the parking space management machine is based on a secure network protocol (such as HTTPS) to ensure the security of command transmission.

[0035] The car owner opens the APP applet on the mobile phone and enters the remote control interface after logging in and authenticating. There is a button to control the parking lock on the interface. When the car owner needs to remotely operate the parking lock (such as when a friend parks for him or she temporarily authorizes others to park), click the corresponding button, and the APP will send the remote control command to the parking management integrated machine via Bluetooth or Wi-Fi (depending on the device connection status), and the parking management integrated machine will then forward the command to the electronic parking lock to remotely open or close the parking lock.

[0036] The intelligent alarm method in this embodiment: The intelligent alarm function is realized by using sensor technology and software algorithms. A variety of sensors can be set in the parking space management integrated machine and the electronic parking space lock, such as vibration sensors, illegal intrusion detection sensors, etc. At the same time, the time management and logical judgment algorithms in the system are combined to determine abnormal situations.

[0037] When the vibration sensor detects abnormal vibrations in the electronic parking lock or near the parking space (perhaps someone is trying to destroy the parking lock or illegally move the vehicle), or the illegal intrusion detection sensor detects someone entering the parking area when the parking lock is not opened, the sensor transmits the signal to the parking management machine. The information management module combines the current time (such as non-normal vehicle entry and exit time) and system logic to determine whether it is an abnormal situation. If so, the alarm module is triggered. The alarm module can realize the alarm function through a variety of methods such as sound alarm (sounding an alarm at the parking management machine), pushing alarm messages to the client (notifying the car owner), and sending alarm information to the property backend (notifying the property staff to deal with it in time).

[0038] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
