Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0024] A multifunctional centralized control device for conferences includes a protective box 101. A protective cover 102 is bolted to the bottom of the protective box 101. An adhesive strip 103 is fixedly installed on one side of the protective cover 102. After the protective box 101 and the protective cover 102 are fixed together, a chamber 104 is formed. A control motherboard 105 is fixed to the protective box 105 with bolts. The heat-generating point of the control motherboard 105 is attached to a heat spreader 107 with thermal grease. The heat dissipation end of the heat spreader 107 is connected to the cooling end of a semiconductor board 108 with thermal grease. The heating end of the semiconductor board 108 faces a heat dissipation window 109. An exhaust fan 110 is bolted to the heat dissipation window 109.

[0025] The heat dissipation window 109 is located at the top of the protective box 101. An air inlet window 111 is provided on the side of the protective box 101 adjacent to the heat dissipation window 109. A filter mesh 112 is installed inside the protective box 101 on the side of the air inlet window 111 by bolts.

[0026] The above solution forms a sealed chamber by bolting the protective box and cover, achieving physical protection and electromagnetic shielding for the internal components. By controlling the thermal grease between the motherboard's heat-generating area and the heat spreader, the core heat source can be quickly dissipated. The close connection between the heat spreader and the cooling end of the thermoelectric cooler generates uniform heat distribution and actively transfers heat. The design of the thermoelectric cooler's heating end facing the heat dissipation window allows for forced exhaust of accumulated heat using an exhaust fan. The combination of the air intake window and filter cloth ensures clean intake of external air while preventing dust accumulation within the chamber. Adhesive strips prevent movement during overall placement.

[0027] In this embodiment, preferably, a display screen 113 is installed through the protective box 101 on the side away from the air intake window 111, an indicator light 114 is fixedly installed on the protective box 101 adjacent to the display screen 113, and a USB interface 115 is installed through the protective box 101 adjacent to the indicator light 114.

[0028] With the above solution, the display screen installed across the side away from the air intake can display the equipment's operating parameters and operation interface in real time; the indicator lights set near the display screen can provide feedback on power status and fault warnings through color changes; and the USB interface on the side of the indicator lights can enable plug-and-play data transfer from external storage devices.

[0029] In this embodiment, preferably, the protective box 101 has an infrared learning window 116 on the side adjacent to the USB interface 115. The infrared learning window 116, the display screen 113, the indicator light 114 and the USB interface 115 are respectively fixedly connected to the control motherboard 105 through flexible wires.

[0030] The above solution, through the opening design of the infrared learning window, can receive and learn infrared remote control signals; by connecting the display screen, indicator lights, USB interface and infrared learning window with flexible wires, the stability of signal transmission can be ensured and the circuit damage caused by mechanical vibration can be reduced.

[0031] In this embodiment, preferably, a first power interface 118 is installed through the protective box 101 on the side away from the infrared learning window 116, a second power interface 119 is installed through the protective box 101 on the side adjacent to the first power interface 118, and a network interface 120 is installed through the protective box 101 on the side adjacent to the second power interface 119.

[0032] The above solution, through the dual-power supply design of the first and second power interfaces, enables seamless switching and redundancy protection of the main and backup power supplies; through the through-installation of the network interface, a high-speed wired data transmission channel can be established to ensure real-time response to conference control commands.

[0033] In this embodiment, preferably, two sets of RS485 interfaces 121 are installed through the protective box 101 on the side adjacent to the network interface 120, an RS232 interface 122 is installed through the protective box 101 on the side adjacent to the RS485 interface 121, and an infrared transmitter 123 is installed through the protective box 101 on the side adjacent to the RS232 interface 122.

[0034] The above solution, with its symmetrical layout of two sets of RS485 interfaces, allows for the simultaneous connection of multiple audio devices while avoiding signal crosstalk; the independent setting of the RS232 interface ensures compatibility with traditional control terminal devices; and the directional installation of the infrared transmitter port enables the precise transmission of learned control signals to the target device.

[0035] In this embodiment, preferably, an I / O digital interface 124 is installed through the protective box 101 on the side adjacent to the infrared emitting port 123, a high-definition input interface 125 and a high-definition output interface 126 are respectively installed through the protective box 101 on the side adjacent to the I / O digital interface 124, and a relay port 127 is installed through the protective box 101 on the side adjacent to the high-definition input interface 125.

[0036] The above solution integrates an I / O digital interface to receive external sensor signals and intelligently adjust environmental parameters; the independent channel design of high-definition input and output interfaces enables bidirectional transmission of lossless audio and video signals; and the high-power control function of the relay port can safely drive high-power external devices.

[0037] In this embodiment, preferably, the relay port 127, the first power interface 118, the second power interface 119, the network interface 120, the RS485 interface 121, the RS232 interface 122, the infrared transmitter port 123, the IO digital interface 124, the high-definition input interface 125, and the high-definition output interface 126 are respectively soldered to the control motherboard 105 via pins.

[0038] The above solution eliminates poor contact caused by loose connectors by directly soldering all interface pins to the control motherboard; the modular and centralized layout of the interfaces simplifies cable management and improves equipment maintenance efficiency.

[0039] In this embodiment, a multifunctional centralized conference control device is used such that, when the protective box 101 and the protective cover 102 are tightly fixed with bolts to form a sealed chamber 104, the internal control main board 105 is bolted to the center of the chamber 104. The heat generated in its heating area is quickly conducted to the surface of the heat spreader 107 through a tightly adhered thermal grease. The high thermal conductivity of the heat spreader 107 is used to evenly diffuse the heat to the entire heat dissipation end. The heat dissipation end of the heat spreader 107 is in seamless contact with the cooling end of the thermoelectric cooler through another layer of thermal grease. The thermoelectric cooler transfers heat from the cooling end to the heating end based on the Peltier effect. The heat generated at the heating end is accelerated by the heat dissipation fins that are tightly attached to the inside of the heat dissipation window 109. At this time, the exhaust fan 110 installed on the heat dissipation window 109 starts to operate. Forced airflow is exhausted outward from the heat dissipation window 109 at the top of the protective box 101. Simultaneously, the air intake window 111 at the lower side wall of the protective box 101 draws in external air under negative pressure. A multi-layer composite filter cloth 112 installed inside the air intake window 111 provides double interception of dust from the external air. The outer stainless steel mesh blocks large particles, while the inner electrostatic fiber layer adsorbs fine dust, ensuring the cleanliness of the air entering the chamber 104. The clean airflow forms a diagonal circulation path within the chamber 104, flowing in through the air intake window 111 and along the surface of the heating area, absorbing residual heat from the control motherboard 105 and surrounding components. Finally, carrying the heat, it is efficiently exhausted through the heat dissipation window 109, achieving dynamic temperature balance within the equipment. The control motherboard 105 (using a PVC circuit board, integrating an ARM Cortex) The A7@Max.1.3GHz chip, DDR3 4G RAM, and 2GFlash flash memory, under stable operating conditions, maintain signal connection via flexible wires to the display screen 113, indicator lights 114, USB interface, and infrared learning window 116, which are installed through the side wall of the protective box 101. The display screen 113 displays the device's operating status and conference control parameters in real time. The indicator lights 114 provide feedback on power, network, and fault information through color changes. The USB interface provides a plug-and-play data transmission channel for external storage devices. The infrared learning window 116 receives remote control signals and completes code learning. The control motherboard 10... 5. Simultaneously manage the power distribution of two sets of power interfaces. The first power interface 118 is connected to the main power supply line, and the second power interface 119 serves as a redundant backup. The network interface 120 establishes a wired data transmission channel. The two sets of RS485 interfaces 121 and RS232 interfaces 122 are respectively connected to the audio equipment and environmental control module in the conference system. The infrared transmitter 123 sends the learned control signals to the controlled equipment. The IO digital interface 124 receives external sensor signals. The high-definition input and output interfaces transmit lossless audio and video signals through the HDMI protocol. The relay port 127 controls the start and stop of external high-power devices.All electrical pins of the interfaces are integrated onto the corresponding pads of the control motherboard 105 by soldering, eliminating the risk of loose connectors and ensuring the stability and anti-interference capability of signal transmission. During equipment operation, the synergistic effect of the semiconductor cooling chip and the forced air cooling system keeps the temperature of the core components below the safe threshold. The composite filtration system significantly reduces the internal dust accumulation rate. The modular layout of multiple interfaces significantly improves cable management efficiency. The overall structure achieves high-density functional integration within a limited space, meeting the stringent requirements of the conference environment for equipment reliability, quiet operation, and ease of use.
