Detailed Implementation

[0016] A networked electronic screen security management system includes a video control center 1 and several security terminals 3. The video control center 1 and each security terminal 3 are connected and controlled by a networked cloud monitoring system 2. Each security terminal 3 includes an electronic screen 31 that plays content. The networked cloud monitoring system 2 includes a content playback control security monitoring system and a hardware connection security monitoring system within the security terminal 3. The content playback control security monitoring system is used to perform high-precision monitoring of the content played on the electronic screen 31, and the hardware connection security monitoring system is used to monitor the hardware connection security of the security terminal 3.

[0017] In this embodiment, the security terminal 3 includes an electronic screen 31, a broadcast control box 36, and a main control box 37. The video control center 1 connects to the main control box 37 in each security terminal 3 via the network-connected cloud monitoring system 2, and sends commands to the main control box 37 via a 4G or 5G network. The main control box 37 in each security terminal 3 transmits the execution status back to the video control center 1 via a 4G or 5G network. The electronic screen 31 includes various types of electronic media display formats, including large screens for city landmarks, small screens, electronic screens in communities, electronic screens at bus stops, and electronic screens in other scenarios.

[0018] In this embodiment, the hardware connection security monitoring system within the security terminal 3 includes an electronic screen 31, a power distribution box 38, a main control box 37, a video processor 33, and a playback control box 36. The power distribution box 38 is connected to the electronic screen 31 and the main control box 37, providing them with power. The main control box 37 and the playback control box 36 are connected via a network cable. A video processor 33 is installed between the playback control box 36 and the electronic screen 31. The video processor 33 converts the uncompressed digital audio and video signals transmitted from the playback control box 36 into digital signals that can be played by the electronic screen 31.

[0019] In this embodiment, an HDMI monitoring box 34 is provided between the broadcast control box 36 and the video processor 33. The upstream and downstream of the HDMI monitoring box 34 are connected to the broadcast control box 36 and the video processor 33 respectively via HDMI cables. The HDMI monitoring box 34 is also connected to the main control box 37 via a 485 communication cable, and the detection results of the HDMI monitoring box 34 are synchronously fed back to the main control box 37.

[0020] In this embodiment, a network cable monitoring box 32 is provided between the video processor 33 and the electronic screen 31. The upstream and downstream of the network cable monitoring box 32 are connected to the video processor 33 and the electronic screen 31 respectively via network cables. The network cable monitoring box 32 is also connected to the main control box 37 via a 485 communication line, and the detection results of the network cable monitoring box 32 are synchronously fed back to the main control box 37.

[0021] The main control box 37 is responsible for detecting unauthorized plugging and unplugging of various video output interfaces of the electronic screen 31. The HDMI detection box 34 monitors the continuity of the line between the broadcast control box 36 and the video processor 33, and the network cable detection box 32 monitors the continuity of the line between the video processor 33 and the electronic screen 31. Once an unauthorized plugging or unplugging is detected, it may mean that there is an illegal operation. At this time, the main control box 37 can quickly receive the information fed back in real time by the HDMI detection box 34 or the network cable detection box 32, and at the same time instruct the power distribution box 38 to immediately cut off the power to the electronic screen 31, issue an alarm, and send a text message to a designated mobile phone number in an emergency where the system is under illegal attack, effectively preventing the electronic screen 31 from displaying illegal content and avoiding adverse social impact.

[0022] In this embodiment, a capture box 35 is also included, used to capture data of the playback content. One end of the capture box 35 is connected to the playback control box 36 via an HDMI cable, and the other end is connected to the main control box 37 via a network cable. The capture box 35 can capture the video images output by the playback control box 36 in real time and analyze the media frame by frame. By comparing the similarity between the images in the media content and the images of the video detection box itself, the number of times the video is played can be accurately recorded.

[0023] In this embodiment, the content broadcast control security monitoring system includes an electronic screen 31, a broadcast control box 36, a broadcast control cloud 4, and a monitoring cloud 5. The monitoring method of the content broadcast control security monitoring system includes the following steps: S1. Submit the video source to be played to the video control center 1. The video source is manually reviewed to confirm that it meets the playback requirements. S2. After the source content is approved, the source is mirrored (i.e., the approved source is re-recorded and output in a special playback format to prevent the source from carrying viruses), forming a mirrored source file. S3. Upload the mirrored source files to the monitoring cloud 5 for filing; S4. Upload the mirrored source file to the broadcast control cloud 4; S5 and Broadcast Control Cloud 4 simultaneously send playback instructions and pre-play content to Broadcast Control Box 36. The pre-play content is the mirrored video source uploaded to Broadcast Control Cloud 4. After receiving the instruction, S6 and broadcast control box 36 compare the pre-broadcast content sent by broadcast control cloud 4 with the mirrored source file filed in monitoring cloud 5. S7. The comparison results include the following two situations: S7-1, The comparison failed, meaning that the pre-play content issued by the broadcast control cloud 4 is inconsistent with the mirrored source material filed in the monitoring cloud 5, and there is a possibility that the playback source material has been hacked and tampered with by software. The power supply of the distribution box in the security terminal 3 is turned off, and an alarm is issued at the same time. S7-2, Comparison passed, meaning that the pre-play content issued by the broadcast control cloud 4 is consistent with the mirrored source of the video file registered in the monitoring cloud 5, and the electronic screen 31 plays according to the time and number of times specified in the playback instruction; S8. Once the publication is complete, the broadcast control box 36 will disconnect from the network, or automatically disconnect from the network after a timeout.

[0024] The process of steps S1-7 is called uploading. The entire monitoring method adopts three steps: manual review, monitoring cloud 5 filing, and comparison of source files to ensure that the content finally played on the electronic screen 31 will not be tampered with by software intrusion, thus ensuring the security of the played content.

[0025] In this embodiment, each electronic screen 31 is connected to a main control box 37. The main controller establishes identity information for each electronic screen 31, enabling unified access, unified management, and unified broadcast control.

[0026] In this embodiment, the electronic screen 31 is connected to a fan, an air conditioner, and a temperature and humidity controller. The digital temperature and humidity controller detects data and provides real-time feedback on the temperature and humidity of the electronic screen 31. The temperature and humidity of the device can be manually or automatically controlled, and the information is transmitted to the main control box 37. The backend can also remotely set the automatic power-on / off temperature, for example, automatically turning off the screen when the temperature exceeds the product's set safe operating temperature of 65 degrees Celsius.

[0027] In this embodiment, dual monitoring of hardware and software is achieved, which greatly improves the level of security control of the electronic screen 31.
