Description

Technical Field

[0001] The present invention relates to the field of aircraft load management, and in particular to an expandable universal airborne mission management system. Background Art

[0002] With the continuous increase in the types of special manned or unmanned aircraft products, the types of installed mission payloads are also increasing. There are many problems in how to achieve comprehensive management of different types of mission payloads. The existing technology usually requires different mission payloads to be equipped with customized management devices designed to achieve the management of their own mission payloads. When multiple mission payloads are installed on the same aircraft platform, how to uniformly schedule, manage, convert interfaces, store data, and download data for mission payload equipment becomes very complicated, and more equipment is used. The universal mission payload management system has become very important, and it will achieve the goal of universalization from multiple aspects such as payload data interface, mission payload control and status feedback, data storage, and payload data download; the mission payload system commonly hung on general aircraft is composed of aerial cameras, optoelectronic pods, multi-function radars, laser fluorescence detectors, and other mission payloads, which are composed of their front-end detection units and corresponding display and control equipment. Due to the limitation of data link bandwidth, generally only one (or two) mission payload target information (such as images, points, etc.) is transmitted in real time. At this time, a selection device is needed to complete the mission payload target information path selection. It is planned to use an airborne mission management system to complete this function. The airborne mission management system can realize the access, management, storage, display and control, and download functions of different types of aircraft and multi-mission payload equipment.

[0003] However, the current designs of airborne mission management systems all design the Windows operating system and the embedded operating system separately. Since it is more difficult to develop the two operating system software compatible with one mission management computer, and the compatibility and stability of the system in software and hardware are higher, the existing airborne mission management systems are not integrated together and cannot achieve the commonality of the two operating systems. Summary of the invention

[0004] The purpose of the present invention is to provide an extensible universal airborne mission management system, which has common functions for manned aircraft and unmanned aircraft, can be adapted according to different payload equipment requirements, does not require secondary development for different payload equipment, and has strong expansion capabilities.

[0015] The task management unit realizes the functions of uploading, loading, returning and modifying task data;

[0016] The payload equipment monitoring unit is used for payload command control. It sends control commands to the mission payload equipment through the bus to realize payload equipment control. It receives payload working status data sent by the payload data interface module through the bus and monitors the payload working status and data, including initialization data and real-time flight data.

[0017] Access and distribution unit: realizes the access, automatic distribution, audio signal management and conversion of signals and data of the payload data interface module and the data transmission interface module, as well as the access, collection and transmission of bus data;

[0019] Furthermore, the mission data includes mission route planning, mounting scheme, payload initialization parameters, air traffic control equipment configuration parameters, and signal mapping relationships.

[0020] Furthermore, the uploading, loading, transmitting back and modifying of the mission data are specifically as follows: the mission management unit uploads the mission data through the data link before the flight or loads the mission data through the local ground inspection software, and can change the mission data during the flight, receive and parse the control instructions from the data transmission interface module, switch the control mode between the program control mode and the instruction mode according to the control instructions, and generate control instructions according to the control authority, control mode, mounting scheme and mission route conditions; when there are multiple independent data links, manage the control authority of the ground control instructions from different data links; in manned aircraft, manage the control authority from the ground payload remote control instructions and the airborne display and control system.

[0021] Furthermore, the real-time flight data in the payload equipment monitoring unit includes position, attitude and speed.

[0022] Furthermore, the signals and data received and distributed by the access and distribution unit include: video signals, synchronization data, remote control and telemetry data, and pulse-per-second signals.
