Description

Technical Field

[0001] The present invention relates to the technical field of aircraft bus communication and interface services, and in particular to an assembleable aircraft ORU service unit. Background Art

[0002] Assembled spacecraft have revolutionized the traditional form of aerospace products. Various orbital replaceable units (ORUs) are mounted on the center wall of the spacecraft to meet different missions. The intelligent modular satellite iBOSS project, funded by the German DLR, aims to develop a new type of modular spacecraft capable of receiving services and being assembled on orbit. iBOSS transforms the subsystems of traditional satellites into specific standard modules and reassembles these modules through standard interface connections to form maintainable modular spacecraft. Spacecraft designed based on this approach are replaceable, maintainable, and upgradeable. The reconfigurable science and exploration satellite ROSE proposed by NASA's Goddard Space Flight Center contains six relatively small modules, each of which has a module interface unit (MIU) that provides a standard electrical interface between the module and the spacecraft. The module interface unit provides the basic framework for a distributed integrated electronic design approach.

[0003] Functions such as analog telemetry acquisition, remote control command actuation, serial bus communication, and power drive control are the senses, tentacles, and nerves of the aircraft. They are distributed throughout every compartment and ORU of the aircraft and are the core of the entire aircraft's status monitoring, operational control, and data transmission. A literature review of existing technologies reveals that the status of interface service units is typically determined by summarizing the requirements of the entire aircraft.

[0004] For example, patent application number CN114513244B, "Spacecraft Integrated Intelligent Information System," discloses an integrated modular architecture based on a shared resource mechanism, constructed from a series of standardized, universal hardware modules. Based on a unified electronic architecture and standardized hardware modules, it employs a switching network to ensure high-reliability, high-bandwidth data transmission, creating a universal, open hardware platform for space-based intelligent computing, onboard processing, efficient transmission, and network collaboration. Patent application number 201810547745.8, "A Satellite Intelligent Open Integrated Electronic System," discloses a universal integrated electronic system architecture, including a central control module, a multi-level bus data conversion module, and a low-speed telemetry acquisition and remote control distribution module. The central control module forwards commands to the multi-level bus data conversion module via a high-speed bus. The multi-level bus data conversion module forwards commands to the low-speed telemetry acquisition and remote control distribution module via a medium-speed bus. The low-speed telemetry acquisition and remote control distribution module then forwards commands to the satellite's non-fast real-time control equipment via a low-speed bus. Command control is achieved through layer-by-layer forwarding across high-, medium-, and low-speed multi-level networks. Application No. 201811392208.7, "An Integrated Interface Control Device and Onboard Integrated Electronic System," discloses an integrated interface control device that enables data exchange between an integrated electronic management unit and other individual devices in the integrated electronic system. The device receives remote control packets from the management unit via a serial communication unit and routes them to other individual devices. It also receives telemetry packets from other individual devices via the serial communication unit and forwards them to the management unit. The device can parse remote control packets and send OC commands to control the power distribution module. Patent Publication No. CN106411571B, "A Reconfigurable Onboard Electronic System," discloses a reconfigurable onboard electronic system. This invention replaces the existing shared bus network or point-to-point connections with a switched network, focusing on networking and information, and enhancing system reliability through redundant design. In this reconfigurable onboard electronic system, devices exchange data via an onboard network switch. The onboard network switch consists of a payload switch and a platform switch, which are connected to the payload switch via a payload network interface. Payload-related devices in the onboard electronic system are connected to the payload switch, while platform devices in the onboard electronic system are connected to the platform switch.

[0005] However, the use of traditional interface expansion units cannot meet the local service needs of telemetry, remote control, communication, drive and other interfaces in each ORU area of the aircraft.

[0006] Regarding the connection between the ORU and the aircraft itself, a literature search of existing technologies revealed that existing research focuses primarily on mechanical and electrical connection interfaces, with less attention paid to specific interface services. For example, patent publication number CN113873797B, "A Standardized Integrated Interface for On-Orbit Replaceable Units: Electromechanical, Thermal, and Information Integration," discloses an integrated interface consisting of a frame and capture adapter module, a mechanical locking module, a high-voltage and information transmission module, a control module, and a heat exchange module, but does not specifically address electrical interfaces or information networking solutions.

[0007] Regarding the regional control and interface service requirements within the ORU of an assembleable aircraft, the following issues exist:

[0008] 1. To meet the regional management and control needs within each ORU, a universal and unified regional control center needs to be built to meet the requirements of ORU regional control and joint collaborative control with the aircraft itself;

[0009] 2. In view of the differences in the types and quantity of telemetry, remote control, communication, drive and other interfaces within each ORU, it is necessary to build a universal and unified regional interface service center to meet the regional interface service requirements of ORUs;

[0010] 3. To meet the regional low-speed, high-reliability, healthy data transmission, medium-speed, high-precision mission data transmission, and high-speed, high-bandwidth payload data transmission requirements within each ORU, it is necessary to build a universal, unified regional network exchange center to meet the requirements for building branch networks for the ORU regional management plane, control plane, and data plane.

[0011] 4. In order to meet the data transmission requirements of the management plane, control plane, and data plane between each ORU and the aircraft body, the ORU needs to provide a bearer environment for the management plane, control plane, and data plane backbone network, relying on the ORU to support the reliable construction and continuous replacement evolution of the backbone network.

In this case, the ORU network communication module's control plane backbone network interface is directly connected to the aircraft control switching module. Similarly, if the ORU performs switching functions for the aircraft's data plane backbone network, the ORU service unit must be configured with an aircraft data switching module.
