Description

Technical Field

[0001] The present invention relates to the field of security technology, and in particular to an intelligent security management system based on 5G, AI and UWB positioning technologies. Background Art

[0002] Intelligent security management is a mode that uses advanced technologies such as the Internet of Things, big data, and artificial intelligence to achieve intelligent, data-based, and refined operational management of security equipment. It can be widely used in finance, logistics, e-commerce, education, and other fields that require a large number of people in and out, goods movement, information confidentiality, and other security needs. The advantages of intelligent security management are: 1. High security efficiency: Through intelligent management, remote monitoring, real-time warning, and rapid response can be achieved to improve security efficiency; 2. Reduce operating costs: Intelligent management can reduce the workload of human inspections and reduce labor costs. At the same time, through data analysis, safety hazards can be discovered in advance and the occurrence of safety accidents can be reduced; 3. Improve user experience: The intelligent access control system can realize face recognition, card swiping recognition, etc., to improve user experience; 4. Improve corporate image: Intelligent security can enhance the company's security image and enhance customer trust.

[0003] Most existing intelligent security management systems rely on traditional video surveillance and personnel patrol methods, which have many limitations in complex industrial environments. For example, traditional monitoring systems cannot accurately locate personnel positions in real time, and have limited management and control capabilities for high-risk work areas. In addition, existing positioning technologies, such as GPS and RFID, are often limited by signal interference and positioning accuracy in industrial environments, making it difficult to meet high-precision and real-time requirements. Intelligent security management systems need to use cameras with more data to collect images of on-site operations and upload them to the host computer to replace manual inspections. However, the more cameras there are, the better. The more cameras there are, the more difficult it is to manage, which also leads to an increase in the workload of manually reviewing the content of the images. Specifically, the current intelligent security management system still needs to be improved in the following aspects: 1. Insufficient positioning accuracy: Traditional positioning technologies such as GPS have weak signals and low positioning accuracy in industrial plants and cannot meet the needs of accurate positioning of personnel.

[0004] 2. Limited real-time monitoring capabilities: Traditional monitoring systems lack the ability to analyze real-time data (image content) and are unable to quickly identify and respond to abnormal behavior.

[0005] 3. Low system integration: There is a lack of effective data interaction and integration between different security systems, resulting in serious information island phenomenon, difficulty in manual review and low management efficiency.

[0006] 4. Poor scalability and flexibility: Existing systems are often difficult to expand flexibly according to actual needs and cannot adapt to changes in future business development. Summary of the invention
