[0053] The open layer 170 is used to provide an API interface and an authorization mechanism to allow external access.

[0054] In the embodiment of the present invention, the front-end equipment includes at least one type of camera IPC and network video recorder NVR, which is used to collect video data in the park.

[0055] The device layer is the foundation of the entire video aggregation platform, mainly including various types of camera IPCs, network video recorders (NVRs) and other hardware devices. These devices are responsible for collecting video data and are the starting point of information sources.

[0056] Various types of camera IPCs have different functions and features to meet the needs of various monitoring scenarios in the park. For example, the camera IPC may include the following components:

[0057] High-definition image acquisition unit: collects high-resolution video images to ensure the clarity and details of the video images, and provides accurate visual information for subsequent video analysis and monitoring;

[0058] Wide dynamic range imaging module: Automatically adjusts exposure parameters under different lighting conditions, such as strong direct light, shadow areas, etc., to ensure uniform brightness and contrast of the image and obtain clear and discernible video images;

[0059] Low-light enhancement function component: In dark environments, such as campus roads and parking lots at night, it can enhance the brightness and clarity of images, effectively improving the camera's monitoring capabilities in low-light environments;

[0060] Intelligent PTZ control device: It can realize horizontal and vertical rotation of the camera, as well as lens zoom and focus operations, so as to facilitate remote control of the camera's shooting angle and field of view, and realize accurate monitoring of specific areas in the park;

[0061] The data transmission interface has a variety of data transmission interfaces, such as Ethernet interface and wireless transmission interface (such as WIFI, 5G, etc.), to ensure that the collected video data can be transmitted to the network layer stably and efficiently.

[0062] The network video recorder (NVR) is used to store and manage video data collected by front-end devices. For example, it may include the following components:

[0063] Large-capacity storage device: built-in large-capacity hard disk or support for external storage devices, capable of storing long-term video data to meet the storage needs of park video surveillance data;

[0064] Video data encoding and compression unit: Use efficient video encoding formats (such as H.264, H.265, etc.) to encode and compress the collected video data, reducing the data storage space and transmission bandwidth while ensuring video quality;

[0065] The data management and retrieval function module can classify, manage, mark and index the stored video data, so that users can quickly retrieve and query the video data of a specific time and place, and improve the efficiency of data management and use;

[0067] Backup and recovery module: It has the ability to automatically back up video data regularly and quickly restore data when it is lost or damaged, ensuring the security and integrity of video data.

[0068] In an embodiment of the present invention, the network layer is used to build a transmission network for each front-end device and a shared transmission network for information exchange between the device layer and the system through one or more network transmission methods such as 5G, WIFI, local area network and the Internet; when transmitting video streams and business data, encryption is performed by adopting national encryption algorithms and private encryption algorithms.

[0069] The network layer includes all network infrastructures that connect various layers, ensuring high-speed data transmission and network stability. The "network layer" builds a front-end equipment transmission network and an information exchange shared transmission network. The front-end equipment transmission network uses 5G, WIFI, LAN, Internet and other network transmission methods to enable front-end equipment to access the park's shared exchange platform through the network.

[0070] The network layer integrates multiple network transmission methods such as 5G, WIFI, LAN, and the Internet to form a complementary network transmission system to meet the network access needs of different areas and scenarios in the park. In densely populated areas or scenarios that require high-speed mobility (such as park patrols), 5G or WIFI networks are preferred to ensure real-time transmission of video data; in relatively fixed areas with high bandwidth requirements (such as monitoring centers), stable and high-speed data transmission can be achieved through LANs or the Internet.

[0071] Deploy high-performance firewalls and intrusion detection systems (IDS) / intrusion prevention systems (IPS). The firewall can control access to network traffic based on preset security policies to prevent external illegal access and leakage of internal sensitive data; IDS / IPS monitors network traffic in real time, identifies and prevents various network attacks, such as hacker intrusion, malware propagation, DDoS attacks, etc., to ensure the security and stability of the network layer.

[0072] Encryption technology is used to encrypt and transmit video data and sensitive business data, supporting national encryption algorithms and industry standard encryption algorithms (such as AES, RSA, etc.). Data is encrypted before transmission to ensure that the data is not stolen or tampered with during network transmission. Only authorized recipients can use the corresponding decryption key to decrypt the data, ensuring the confidentiality and integrity of the data.

[0073] Establish a network security authentication and authorization mechanism to authenticate the identity of devices accessing the network and users accessing system resources. Use certificate-based authentication methods (such as digital certificates, CA authentication) or other security authentication technologies (such as Oauth, JWT, etc.) to ensure the legitimacy of devices and users. According to the permission settings of users and devices, perform detailed authorization management on the network resources, services, and data they access to prevent unauthorized access and operations.

[0074] Scan the network for vulnerabilities regularly to promptly discover security vulnerabilities in network devices, operating systems, applications, etc. It has the function of automatically or manually triggering vulnerability repair, which can timely update system patches and upgrade software versions, reduce the risk of network system attacks, and ensure the security of the network layer.

[0077] Specifically, the access layer performs strict identity authentication on the accessed devices to ensure that only legally authorized devices can access the system. Authentication methods based on digital certificates and device unique identification are used to prevent security risks caused by illegal device access. At the same time, according to the device type and permission settings, the device access scope, accessible resources, etc. are finely authorized to ensure the security of the system.

[0078] During device access and data transmission, encryption technology is used to ensure secure data transmission. It supports encryption of transmitted data to prevent data from being stolen or tampered with at the access layer, and uses secure and reliable encryption algorithms (such as national encryption algorithms, industry standard encryption algorithms, etc.) to ensure data confidentiality and integrity.

[0079] The access layer has the function of status monitoring and automatic reconnection of access devices, and monitors the online status of access devices in real time. Once the device is offline or there is a connection abnormality, it can automatically try to reconnect to ensure the continuous access of the device. At the same time, the quality of the access link is monitored and optimized to ensure the stability of data transmission and reduce data transmission interruptions caused by network fluctuations.

[0080] The access layer monitors and controls the traffic of access devices in real time to prevent individual devices from occupying too many network resources and affecting the normal access and data transmission of other devices. According to the overall system load and device priority, the access bandwidth is reasonably allocated to ensure the overall stable operation of the access layer.

[0081] The data layer is responsible for storing and managing all video data, image data, and business data.

[0082] The data layer can adopt a distributed storage architecture, using a distributed file system or object storage technology to build a data storage architecture, and store video data, image data, and business data in multiple storage nodes in a dispersed manner, with the following features:
