[0002] Museum remote playback equipment refers to the use of modern information technology to enable visitors to watch or interactively experience the exhibits and content in the museum through the Internet without being present in person. These devices usually include video playback systems, audio guide systems, virtual reality VR technology or augmented reality AR technology, and other digital display methods. Museum remote playback equipment not only allows the display and protection of cultural heritage to be no longer restricted by time and space, but also improves the convenience and immersion of exhibitions, provides visitors from all over the world with a richer and more personalized exhibition experience, and promotes the dissemination of cultural heritage and the expansion of educational functions. The security control of museum remote playback equipment is crucial because it involves the transmission and storage of a large amount of cultural assets and sensitive information. Effective security control can prevent unauthorized access, data leakage or malicious attacks on the system, and ensure the integrity and confidentiality of exhibits and explanations. In addition, security control can also prevent the negative impact of equipment failure or data corruption on the visitor experience, and ensure the smooth and safe experience of users during remote viewing. By strengthening security measures, museums can better protect digital assets and avoid infringement or abuse of cultural heritage, thereby promoting its healthy and sustainable development and dissemination.

[0003] At present, traditional remote device security control systems are not fully suitable for museum remote playback equipment. They lack specific mechanisms for the protection of cultural assets and are difficult to effectively prevent the illegal theft or tampering of digital cultural relics. In addition, the timeliness and effectiveness of equipment management are also insufficient, and there is a lack of unified evaluation standards, making it difficult to provide consistent security guarantees. Summary of the invention

[0050] In the formula, Indicates the percentage of remote playback devices that are in the enabled state to the total number, i.e., the enable rate of remote playback devices. This accurately counts the device utilization rate and ensures the healthy state of high-frequency used devices.

[0051] The calculation process of recovery factor Hsx is as follows:

[0052] From the remote playback devices whose operation status is turned on, they are classified into movable playback devices YS and fixed playback devices GS according to the playback function. Among them, the remote playback devices with wearable function are classified as movable playback devices YS, such as rental guide machines and virtual tour guide devices, which only serve tourists visiting offline.

[0067] If the IP address of the i-th user account has been changed ≥ 2 times, the risk score Fxpf of the i-th user account will increase by 1 point;

[0068] In a single visit to an exhibition area, if the visit duration of the i-th user account is ≥ 1.5 times the interaction duration Hdsc of the exhibition area, the risk score Fxpf of the i-th user will increase by 2 points, which will reduce the cost of manual monitoring, quickly identify potential illegal operations, protect the safety of cultural assets, and comprehensively evaluate the strong prevention and control capabilities;

[0069] The early warning management unit is set with a fixed range of opening threshold KQY, recovery threshold HSY and duration threshold SCY.

When the opening rate Kql exceeds the opening threshold KQY, it means that the scheduling space of the museum's remote playback equipment is insufficient, and a corresponding scheduling early warning signal is generated. It is recommended to manage the number of visitors in different time periods and recover the visitors. When the coefficient Hsx exceeds the recovery threshold HSY, it means that the load level of the remote playback device has been overloaded, and a corresponding recovery warning signal is generated. It is recommended to recycle the movable playback device YS or shut down the fixed playback device GS. When the interaction time Hdsc exceeds the time threshold SCY, it means that the layout of the cultural relics in the exhibition area is too tight, and there is a risk of failure of security management. A vulnerability warning signal is generated, and it is recommended to optimize the layout of cultural relics in the exhibition area. The risk score Fxpf≥1 indicates that there is a risk of illegal theft of cultural assets in the exhibition area. A corresponding theft warning signal is generated, and it is recommended to forcibly log off the user account. Intelligent control is timely and effective.

After testing, the battery capacity of the rental tour guide was 100%, the remaining power was 80%, the historical maintenance times were 2 times, and the historical usage time was 100 hours. The calculation formula of the rental tour guide recovery coefficient Hsx is as follows:

[0074]

[0075] In the formula, Represents the ratio of battery capacity to remaining power, and 0.6 represents the evaluation weight for the ratio of battery capacity to remaining power. It represents the ratio of the historical maintenance times to the historical usage time, that is, the maintenance frequency of the rented tour guide. 0.4 represents the evaluation weight for the maintenance frequency. α1+α2=1. According to the weights of α1 and α2, the recovery coefficient Hsx of the rented tour guide is 0.758.
