[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be described in more detail below with reference to the embodiments of this utility model. In the examples, the same or similar reference numerals denote the same or similar components or elements having the same or similar functions throughout. The described embodiments are some, but not all, embodiments of this utility model. The embodiments described below with reference to the embodiments are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. The embodiments of this utility model will be described in detail below with reference to their specific implementation.

[0020] The technical solution for this integrated dome display control device can be divided into the following main steps:

[0021] (1) Startup and initialization

[0022] Power Start-up: When the system starts up, the user can choose to send a start signal to the dome display system via a host computer (remote control) or a touch screen (local control). The main control system in the power control cabinet controls the AC contactors and circuit relays through circuit control board signals to connect the power supply. The AC contactors convert 380V AC power to 220V AC power and supply power to the dome display system, top fan, bottom fan, and video transmission power supply through the circuit relays.

[0023] (2) Local or remote control selection

[0024] Users can choose to control the dome display system via a host computer (remote control) or a touchscreen (local control). The host computer enables remote monitoring and operation, while the touchscreen supports local operation.

[0025] The host computer or touch screen sends operation commands to the main control system, which then coordinates and controls each module according to the commands.

[0026] (3) Environmental monitoring and regulation

[0027] Environmental Information Acquisition: The environmental information monitoring module is responsible for collecting data such as temperature, humidity, and smoke levels inside the dome. The data is transmitted to the main control system via data acquisition boards.

[0028] Automatic adjustment: The main control system sends adjustment signals to the bottom fan through the PWM interface of the control output board based on environmental information, and adjusts the air volume according to actual needs to ensure that the temperature and humidity inside the dome are maintained within a suitable range; the main control system sends control commands to the air cooler through the RS485 interface of the command forwarding board based on environmental information to achieve heat dissipation of the dome.

[0029] The top fans are always on, providing basic cooling for the dome screen and require no adjustment. The bottom fans are controlled via the main control system.

[0030] Alarm function: If the environmental information exceeds the preset safety range (such as excessive smoke or excessive temperature), the main control system can trigger an alarm and take corresponding safety measures, such as shutting down some equipment or starting emergency ventilation.

[0031] (4) Video processing and display

[0032] Multi-source video overlay: The video overlay device can receive multiple video sources and integrate them, and output the partitioned display to different display units, thereby realizing dynamic display of multiple screens and multiple partitions.

[0033] Graphic correction: The graphic correction device receives the video signal that needs to be processed and converts the planar video signal into a curved video signal suitable for dome display.

[0034] Video transmission and playback: The video signal to be sent is converted into an optical signal by the video transmitting device and transmitted to the video relay device. The video relay device converts the received optical video signal into an electrical signal and transmits it to the display unit. The display units cooperate with each other to display synchronously, realizing a 360-degree panoramic high-definition display within the dome screen.

[0035] The video signals that need to be superimposed can be sent sequentially to the video superimposition device, the image correction device, and the video transmission device through a gigabit switch for corresponding processing, and then transmitted to the video forwarding device via optical fiber.

[0036] Video signals that do not require superposition can be sequentially sent to the graphics correction device and the video transmission device through a gigabit switch for corresponding processing, and then transmitted to the video forwarding device via optical fiber.

[0037] (5) Power supply and display control

[0038] Centralized power management: The centralized power control module monitors the power supply of the entire display system and adjusts the power supply status of each display unit (such as brightness adjustment, whether the display unit is powered on or off), to ensure reasonable power distribution and continuous operation of the equipment.

[0039] (6) Real-time monitoring and system adjustment

[0040] System monitoring: The main control system monitors the operating status of each module in real time, and ensures the stable operation of the system through environmental information monitoring modules, centralized power control modules, etc.

[0041] Troubleshooting and Recovery: If a system malfunctions, the main control system can issue corresponding commands through the command forwarding board and control output board to shut down the problematic module or restart the device. After the system recovers, the main control system will automatically return to normal operation.

[0042] (7) Shutdown and System Protection

[0043] Power-off command: Users can send a power-off command via the host computer or touchscreen. Upon receiving the power-off command, the main control system will sequentially shut down each module to ensure data is safely saved and prevent current overload.

[0044] Equipment power failure protection: The main control system gradually disconnects the power supply and safely shuts down the system by controlling the AC contactor and circuit relay through the circuit control board.

[0045] Through this series of steps, the integrated dome display control device can achieve a stable 360-degree panoramic visual display, while ensuring the system's stability and ease of operation, meeting the needs of high-end displays and immersive experiences.

[0046] The functions of each module are described below:

[0047] The touchscreen is electrically connected to the main control system of the power control cabinet to enable local control of the dome screen.

[0048] The display unit has a curved structure, and multiple display units can be spliced ​​together to form a dome screen, allowing users to stand inside the dome screen to view the images displayed by the display unit.

[0049] The environmental information monitoring module is used to collect environmental information such as temperature, humidity, and smoke. The data is then sent to the main control system via the data acquisition board for alarm and temperature and humidity control.

[0050] A centralized power supply module is used to centrally supply power to several display units.

[0051] The centralized power control module is used to monitor and adjust the centralized power supply module, such as brightness and whether the display unit is powered on.

[0052] The bottom fan is located below the dome and is connected to and controlled by the main control system via a control output board. The main control system can adjust the bottom fan according to the information collected by the environmental information monitoring module, thereby controlling the temperature inside the dome to remain constant and making the users inside the dome feel comfortable.

[0053] The video transmission power module is used to power the video forwarding device. The video forwarding device connects to the video transmission device over long distances via optical fiber. The video forwarding device can convert the received optical video signal into an electrical signal and transmit it to the display unit to play the video.

[0054] Video overlay devices can overlay different received video sources to achieve partitioned display of multiple display units.

[0055] Video overlay equipment can receive video signals that need to be processed and correct planar video signals to be suitable for curved dome screens.

[0056] The video overlay device receives the video signal to be sent, converts it from an electrical signal to an optical signal, and sends it to the video forwarding device through optical fiber, thus realizing the long-distance transmission of curved video signals.

[0057] Gigabit switches serve to expand network ports and communicate with video transmission devices, image correction devices, and video overlay devices via Ethernet, enabling them to monitor and control these devices.
