[0028] In order to more clearly explain the control card of the hybrid matrix novel integrated central control function of the present invention, the following Figure 2 The modules in the embodiments of the present invention are described in detail.

[0029] The first embodiment of the present invention is a hybrid matrix control card with integrated central control functions. The modules are described in detail as follows:

[0030] The serial interface of the panel interface 01 is connected to one end of the signal processing module 07, and the second end of the signal processing module 07 is connected to the first end of the central control interface module 02; the network interface of the panel interface 01 is connected to the first end of the network switching module 06, and the second end of the network switching module 06 is connected to the first end of the central control card module 04; the third end of the network switching module 06 is connected to the second end of the central control interface module 02; the second end of the central control card module 04 is connected to the third end of the central control interface module 02; the fourth end of the central control interface module 02 is connected to the first end of the hybrid matrix control card module 03; the third end of the central control card module 04 is connected to the second end of the hybrid matrix control card module 03, and the third end of the hybrid matrix control card module 03 is connected to the backplane connector 05; the power supply module 08 is connected to the power supply port of the hybrid matrix control card module 03 and the power supply port of the central control card module 04, respectively.

[0031] In this embodiment, the signal transmitted by the panel interface 01 is the serial communication signal of the external controllable device and the instruction of the external control client. The serial communication signal is transmitted to the central control interface module 02 for signal processing and feedback, and the instruction of the external control client is transmitted to the central control card module 04 for signal processing and feedback.

[0032] The signal processing module 07 includes a signal conversion chip 21, a digital isolation chip 20 and an isolated power supply 18; the panel interface 01 is connected to the first end of the signal conversion chip 21, the second end of the signal conversion chip 21 is connected to the first end of the digital isolation chip 20, and the second end of the digital isolation chip 20 is connected to the hybrid matrix control card module 04.

[0033] The signal processing module 07 includes a signal conversion chip 21, a digital isolation chip 20, and an isolated power supply 18. The signal conversion chip 21 receives a serial communication signal as input. The signal conversion chip 21's tri-state differential line driver and differential input line receiver convert the serial communication signal into a UART signal, which is then transmitted to the hybrid matrix control card module via the digital isolation chip 20. The input signals of the signal processing module 07 are mostly RS232 / RS485, and the output signal is UART.

[0034] In this embodiment, the network switching module 06 includes a Gigabit Ethernet switch chip that implements the functions of an external switch, saving the cost of an external switch and network cabling. Users simply connect to the external network interface to access the entire hybrid matrix system, transmit commands through the control card, and obtain feedback data.

[0035] In this embodiment, the central control interface module 02 includes an embedded Ethernet controller 19, which integrates a 100M PHY, MAC, internet processor, register manager, memory, and host interface. The first end of the Ethernet controller 19 is connected to the network switch module 06, which is then connected to the hybrid matrix control card module 03 via the host interface 01. The central control interface module 02 is used to convert external input signals into serial or parallel communication signals, and transmit the serial or parallel communication signals to the hybrid matrix control card module 03 via the host interface. The hybrid matrix control card module 03 processes the serial or parallel communication signals and transmits them to the central control interface module 02. The central control interface module 02 then transmits the processed signal instructions to the external interface. The central control interface module 02 primarily processes communication signals, such as UART signals and MDI signals.

[0036] In this embodiment, the hybrid matrix control card module 03 includes an MCU chip and peripheral circuits. These are responsible for receiving central control window opening commands and performing communication functions. The command signals from the hybrid matrix control card module 03 are transmitted via the matrix system's backplane to other boards in the matrix system, enabling functions such as switching audio and video signals.

[0037] In this embodiment, the hybrid matrix control card module 03 also includes a differential line driver receiver module, the input signal of the differential line driver receiver module is a UART signal, and the output is an RS485 signal. The hybrid matrix control card module (03) uses an ST-ST MCU chip. The chip supports 6 groups of UART inputs and 3 groups of SPI, allowing efficient signal processing and complex algorithm execution, and has a highly configurable capability. It can efficiently calculate and store instructions input from the external interface, and control and transmit communication signals to the hybrid matrix system. Each driver and receiver of the differential line driver / receiver has independent input and output pins for full-duplex bus communication design. Hybrid matrix control card module.

[0038] In this embodiment, the central control card module 04 includes a central control core board that supports RMII and RGMII interfaces, full-duplex and half-duplex operation, and TCP segmentation offload and UDP segmentation offload network acceleration. The central control core board is connected to the hybrid matrix's novel integrated central control function control card via a PCI-E slot. The central control card module integrates network interface communication signals connected to the central control interface module and serial low-speed signals from the hybrid matrix control card module, enabling the transmission and implementation of client commands parsed from the network port.

[0039] In this embodiment, the central control card module 04 also includes an RTC circuit module, which serves as its clock circuit. The hybrid matrix control card module controls the RTC circuit module's power enable pin. The central control card module's PCI-E slot connection interface with the new control card includes: one RGMII interface, one debug serial port (UART), a power control pin, and an RTC clock pin.

[0040] In this embodiment, the backplane connector 05 includes: a power on / off unit, an input control unit, an output control unit, and a panel control unit; the power on / off unit includes a level detection circuit, which determines whether the control card is turned on by level changes. The input signal of the backplane connector module (05) is a UART serial port signal and an SPI high-speed serial signal. The backplane connector module (05) is consistent with the backplane connector of the traditional hybrid matrix control card, so that the new control card can adapt to the traditional hybrid matrix architecture. The signal definition of the backplane connector is consistent with the backplane connector of the traditional hybrid matrix, so as to ensure that the control card of the new hybrid matrix integrated central control function can conform to the architecture of the traditional hybrid matrix.

[0041] like Figure 3 As shown, the external controllable device 11 is connected to the central control card module 04 (i.e., the central control core board) via the central control interface module 02. This allows for the sending and receiving of commands from the external controllable device, which includes devices such as cameras and power sequencers that communicate using the RS484 / RS232 protocol. An external video source 14 is connected to the matrix chassis backplane 16 via a matrix input board 15. Audio and video signals are transmitted to the matrix chassis backplane 16. The hybrid matrix control card 10, which integrates central control functions, then switches signals according to commands from the external operating platform 09, transmitting the audio and video signals from the matrix output board 13 to the image display 12.
