Description

Technical Field

[0001] The present invention relates to the technical field of remote control, in particular to a safety control system suitable for remote playback equipment in museums. Background Art

[0002] Museum remote playback equipment uses modern information technology to enable visitors to view or interact with museum exhibits and content online without having to be physically present. These devices typically include video playback systems, audio guide systems, virtual reality (VR) or augmented reality (AR) technology, and other digital display methods. Museum remote playback equipment not only frees the display and preservation of cultural heritage from the constraints of time and space, but also enhances the convenience and immersion of exhibitions, providing visitors from around the world with a richer and more personalized experience, promoting the dissemination and educational benefits of cultural heritage. Security control of museum remote playback equipment is crucial, as it involves the transmission and storage of large amounts of cultural assets and sensitive information. Effective security controls can prevent unauthorized access, data leaks, or malicious system attacks, ensuring the integrity and confidentiality of exhibits and content. Furthermore, security controls can prevent equipment failure or data corruption from negatively impacting the visitor experience, ensuring a smooth and secure user experience during remote viewing. By strengthening security measures, museums can better protect digital assets, prevent the infringement or misuse of cultural heritage, and promote its healthy and sustainable development and dissemination.

[0003] At present, traditional remote equipment security control systems are not fully suitable for museum remote playback equipment. They lack specific mechanisms for the protection of cultural assets and cannot 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.

[0046] The intelligent control module consists of a device evaluation unit, a security assessment unit, and an early warning management unit. The device evaluation unit performs classification processing based on the device data set, and then analyzes the remote playback device activation rate Kql and the recovery coefficient Hsx of each remote playback device in real time.

[0047] The calculation process of the open rate Kql is as follows:

[0048] According to the device data set, filter out remote playback devices with an operating state of on according to the operating state, and mark the number of remote playback devices with an operating state of on as K, and mark the number of remote playback devices with an operating state of off as G, where K+G=n;

[0049]

[0050] In the formula, Indicates the percentage of remote playback devices in the enabled state out of the total number, i.e., the remote playback device enablement rate. This accurately measures device utilization and ensures the health of frequently used devices.

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

[0052] Remote playback devices in the enabled state are classified into portable playback devices YS and fixed playback devices GS according to their playback functions. Remote playback devices with wearable functions, such as rental audio guides and virtual tour guides, are classified as portable playback devices YS, serving only offline visitors. Remote playback devices without wearable functions are classified as fixed playback devices GS, such as video playback devices and augmented reality (AR) devices, serving not only offline visitors but also online user accounts.

According to the weights β1 and β2, the recovery coefficient of the a-th remote playback device is obtained, which accurately evaluates the load level of the two devices and effectively reduces maintenance costs;

[0060] The security assessment unit divides the artifacts into groups according to the exhibition area number based on the artifact dataset and then calculates the interaction duration Hdsc for each artifact group. The calculation process is as follows:

[0061] Based on the cultural relic dataset, cultural relic groups are divided according to the exhibition area numbers. Cultural relic groups with the same exhibition area number are grouped together.

[0062] The number of artifacts in a single artifact group is preset to be e, the number of artifacts displayed via the mobile playback device YS is f, and the number of artifacts displayed via the fixed playback device GS is g, where f+g=e;

[0063]

[0064] In the formula, JS o Indicates the duration of the explanation of the oth cultural relic. The oth cultural relic is displayed through the mobile playback device YS. JS p Indicates the duration of the explanation of the p-th cultural relic. The display of the p-th cultural relic is carried out through the fixed playback device GS. The total duration of explanations by individual cultural relic groups in a single exhibition area is the interactive duration of that exhibition area. This helps avoid overcrowding, improves the visitor experience, and screens popular exhibition areas, providing a basis for decision-making in exhibition area scheduling.

[0065] The early warning management unit analyzes the risk score Fxpf of each user account based on the access data set. The calculation process is as follows:

[0066] The initial value of each user account risk score Fxpf is preset to 0, and then the access record of the i-th user account in the access data set is extracted;

[0067] If the IP address of the i-th user account has 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 be increased by 2 points, which will reduce the cost of manual monitoring, quickly identify potential illegal operations, protect the safety of cultural assets, and comprehensively assess the 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. Combined with the opening rate Kql, recovery coefficient Hsx, interaction duration Hdsc and risk score Fxpf, it evaluates the scheduling space and load level of the museum's remote playback equipment, and determines whether there is a risk of failure in security management of the layout of cultural relics in the exhibition area, and whether there is a risk of illegal theft of cultural assets in the exhibition area. 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 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 close, and there is a risk of failure in security management. A vulnerability warning signal is generated, and it is recommended to optimize the layout of the 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.

[0070] Example 1: In this experiment, the Anhui Provincial Museum was selected as the experimental object. According to statistics, on January 1, the total number of remote playback devices in the museum was 100, and 75 devices were currently in the open state. The opening rate Kql of the museum was calculated as follows:

[0071]

[0072] In the formula, 75% represents the percentage of remote playback devices in the open state among the total number, which is the activation rate of the museum's remote playback devices.

[0073] Example 2: In this experiment, a rental guide was selected as the experimental object. After testing, the battery capacity of the rental guide was 100%, the remaining power was 80%, the number of historical maintenance times was 2, and the historical usage time was 100 hours. The calculation formula for the recovery coefficient Hsx of the rental guide 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 rental guide. 0.4 represents the evaluation weight for the maintenance frequency. α1+α2=1. According to the weights α1 and α2, the recovery coefficient Hsx of the rental guide is 0.758.
