Description

Technical Field

[0001] This invention relates to a wired / wireless communication transmission system. Background Technology

[0002] In the field of modern communication technology, wired communication and wireless communication are the two core transmission methods, each with its own advantages and disadvantages: wired communication is widely used in scenarios with high reliability requirements due to its stable transmission and strong anti-interference capabilities, but it is limited by the laying of transmission lines and has poor mobility; wireless communication does not require the laying of physical lines and has the characteristics of being unrestricted by communication distance, rapid establishment, and good mobility, which can meet the communication needs of mobile scenarios, but it has drawbacks such as transmission quality being easily affected by environmental interference, signal being easily intercepted, poor confidentiality, and being greatly affected by natural factors.

[0003] In existing technologies, wired / wireless communication devices typically adopt a separate assembly structure of "computer system + voice communication system." This type of device has the following significant drawbacks: First, low system integration results in bulky and heavy devices with poor portability, failing to meet the flexible operation requirements of mobile scenarios. Second, high hardware costs and complex assembly hinder mass application. Third, rudimentary human-computer interaction design lacks intuitive operation interfaces and convenient control methods, leading to a poor user experience. Fourth, a single and fixed communication method, often only supporting wired connections to switches, limiting adaptability and the ability to flexibly switch communication modes according to actual scenarios. Fifth, no specific design addresses the confidentiality deficiencies of wireless communication, resulting in insufficient data transmission security.

[0004] With the increasing demands for intelligence, miniaturization, portability, and security in mobile communication scenarios (such as land-based operations and fieldwork), traditional split-type communication devices can no longer meet market needs.

Housing: It adopts a fully sealed, fanless design and is made of high-strength aluminum alloy, which combines lightweight and impact resistance. The surface of the housing is rationally arranged with function buttons, power switch, status indicator lights, and external connectors (including aviation plug interface and debugging interface). The installation position of each component corresponds precisely with the circuit interface. It is also treated with sealing, dustproof, mildewproof, salt sprayproof and vibration-resistant processes to meet the usage requirements of harsh environments such as land vehicles. Physical parameters: The volume is optimized to 250mm×165mm×40mm, and the weight is controlled to within 3kg, making it easy to carry by hand or fix to the launch vehicle with a special bracket.

[0021] The wireless transceiver is a communication relay terminal, including a main control board, wireless communication module, power module, status indicator lights, external connectors, and a housing. Main control board: It adopts a low-power microprocessor and is connected to the wireless communication module, power module, status indicator and external connector through circuits.

[0022] Core features include: Dual communication mode switching function: This device supports both wired Ethernet communication and wireless communication modes. Users can manually or automatically switch between these modes as needed. After switching, the corresponding status indicator light will illuminate to indicate the current communication mode. Wired communication mode: The display and control device and the wireless transceiver device establish a wired connection through the switching module, using fiber optic Ethernet cable as the transmission medium. The transmission path is "display and control device → switching module → fiber optic Ethernet cable → wireless transceiver device → Ethernet → switch". It has a high transmission rate and strong anti-interference ability, and is suitable for scenarios with high requirements for communication stability. Wireless communication mode: The transmission path is "display and control device → wireless communication module → wireless transceiver device → Ethernet → switch", which is suitable for scenarios without transmission lines or requiring mobile operation.

[0023] To address the inherent weakness of wireless communication in terms of security, this device encrypts all transmitted signals (including wired and wireless command and status data). Encryption algorithms can be selected from symmetric algorithms such as AES-256 or asymmetric algorithms such as RSA. The encryption / decryption modules are integrated into the main control boards of both the display and control equipment and the wireless transceiver. Commands or data are encrypted by the encryption module on the transmitting end's main control board and decrypted by the decryption module on the receiving end's main control board, ensuring data security during transmission.

[0024] The human-machine interface is equipped with a color LCD screen and physical function buttons, forming a user-friendly interface. The function buttons are connected to the main control board via circuitry, allowing users to select items, switch communication modes, and issue commands. The button signals are collected and processed by the main control board to execute the corresponding functions. The LCD screen unit is connected to the main control board via a display driver circuit, displaying the launch vehicle's operating status information (such as power status, communication status, etc.), the real-time location information of surrounding vehicles, and operation feedback information in a clear and convenient manner.

[0025] The navigation and positioning function and display control device support the installation of general map software and are compatible with GPS data format and inertial group data format. The location data source is: the GPS module and the inertial group data interface are connected to the main control board through the circuit. After the main control board processes the location data, it controls the LCD screen unit to display the navigation path and the location of surrounding vehicles through the display driver circuit, so as to realize the functions of navigation, vehicle positioning and real-time information display of surrounding vehicles.

[0026] The communication transmission process of this device is as follows: Command issuance process: The user inputs a command through the function keys or touch interface of the display and control device. The command signal is transmitted to the main control board. After processing the command, the main control board selects the transmission path according to the current communication mode—in wired mode, it is sent to the wireless transceiver via the switching module and fiber optic Ethernet cable; in wireless mode, it is sent to the wireless transceiver via the wireless communication module. After receiving the command, the wireless transceiver is processed by the main control board and forwarded to the external switch via Ethernet, thus completing the command issuance. Status feedback process: Status data from external devices is transmitted to wireless transceivers via a switch. The wireless transceivers then forward the data to the display and control device via wired or wireless communication. After processing the data, the main control board of the display and control device transmits it to the LCD screen unit for display via the display driver circuit, thus completing the status feedback. Encryption process: Before the instruction or data is transmitted, the encryption module of the main control board of the sending end (display and control device or wireless transceiver device) performs encryption processing, and the decryption module of the main control board of the receiving end (wireless transceiver device or display and control device) performs decryption processing to ensure the security of data during transmission.
