Any changes or adjustments to their relative relationships, without substantially altering the technical content, shall also be considered within the scope of implementation of this utility model.

[0049] Since the existing Ku-band high-beam rate under the "Global Network" cannot meet the needs of users, in order to improve communication quality and meet the needs of big data networks, a Ka-band high-throughput network is integrated into the "Global Network" to improve the overall network transmission capacity, and global coverage is achieved through a Ka-band and Ku-band dual-band multi-baseband system network.

[0050] like Figures 1 to 3 As shown, this utility model embodiment provides a shipborne Ka / Ku dual-band fusion satellite communication terminal controller architecture, including a controller base 1 and a main control board 2, a switch module 3, a WIFI and expansion module 4, a lighting control board 5, a power supply module 6, and a functional interface module 7 respectively mounted on the controller base 1. This architecture, through the functional combination and corresponding design selection of each module, forms an overall hardware controller architecture that meets the product's functional requirements. Furthermore, it enables protocol communication between the controller architecture and the dual-band fusion antenna and two sets of modems via selectable switching interfaces. Specific settings are as follows:

[0051] Please refer to Figure 1 The main control board 2 is used as the core processor for data processing and protocol communication. The main control board 2 can use, but is not limited to, the Rockchip RK3568 development board as the core processor to meet the requirements of high performance and low power consumption. The main control board 2 has a motherboard WAN port. The input end of the switch module 3 is connected to the motherboard WAN port of the main control board 2 through a circuit. The output end of the switch module 3 is provided with several sets of forwarding WAN ports to expand the motherboard WAN port of the main control board 2, providing a dedicated electrical signal path for any two network nodes connected to the switch module 4, thereby realizing the convergence and separation of two modem service networks and management networks.

[0052] Please refer to Figure 1 and Figure 3The WIFI and expansion module 4 is electrically connected to the main control board 2 via its USB interface. Specifically, the WIFI and expansion module includes a WiFi board and a USB-to-HUB expansion board. The WiFi board and the main control board are connected by a circuit, and the main control board is remotely connected to the mobile terminal through the WiFi board. This allows the main control board to access the wireless network and thus access the wired network, making it easier for the terminal to remotely control the device. The USB-to-HUB expansion board also has an extended WAN port 41, which, in addition to providing the external interface of the main control board 2, can also provide an additional WAN port to assist in subsequent data collection or third-party network access.

[0053] Because USB communication only exists between the host and the device in a USB communication system, and each communication must be initiated by the host, while devices cannot communicate with each other, a HUB is used to expand the interface.

[0054] More specifically, the USB to HUB expansion board is connected to the main control board via a circuit, and the USB to HUB expansion board has a USB signal expansion and conversion chip, which transmits the main control board's USB total signal to the USB signal expansion and conversion chip via the miniPCIE interface, and then further expands and converts it into 4 USB signals before outputting them through the 20-pin terminal.

[0055] Please refer to Figure 1 and Figure 2 The controller base 1 has a control switch 11 and status lights 12 respectively on its front side; the control switch 11 is connected to the main control board 2 by a circuit and is used to perform power on / off operation; the status lights 12 are provided in at least four groups, including power light, Ka network, Ku network and fault light, to indicate the communication network switching status and the overall function operation status in real time through at least four groups of status lights 12.

[0056] Please continue to refer to this. Figure 1 and Figure 2The lighting control board 5 is connected to the main control board 2 and the status lights 12 via circuits to transmit the control signals output by the main control board 2 to the corresponding status lights 12.

Specifically, the communication interface module 51 includes a Ka management interface, a Ka service interface, a Ku management interface, and a Ku service interface, all of which are configured as RJ45 network ports.

[0057] More specifically, the Ka management interface and the Ku management interface are respectively configured with interface gateway, subnet mask and IP address, and the Ka management interface and the Ku management interface can be selectively switched to communicate with the Ka modem or the Ku modem via the OpenAMIP protocol; the Ka service interface and the Ku service interface are respectively configured with the service IP address of the Ka modem or the Ku modem, so as to verify the current satellite network status according to the service IP address of the modem, and at the same time, they can access their respective service networks to realize the function of ship-side IP service data access to the corresponding satellite network.

[0058] Optionally, the selectable switching method includes, but is not limited to, manual switching and automatic switching when the network is disconnected.

[0059] Please continue to refer to this. Figure 1 and Figure 2 The functional interface module 7 is located on the front of the controller base 1, and is connected to the main control board 2 via the switch module 3. Specifically, the functional interface module 7 includes a user local area network (LAN) interface, an ACU interface, and a debugging interface. The LAN interface, ACU interface, and debugging interface are all configured as RJ45 network ports, used to connect to the ship's service network through the LAN interface, and communicate with the currently connected Ka or Ku service interface according to the switching status, thereby realizing the user LAN access to the corresponding baseband network function. At the same time, the ACU interface can be used to access the ACU communication address, port number, gateway, and subnet mask information. In addition, the debugging interface can be used to directly connect to external terminals to assist in troubleshooting.
