Technical Field

[0001] This invention relates to the field of integrated system technology, and in particular provides a master-slave mode control method for an airborne meteorological mission integrated system. Background Technology

[0002] With the increasing frequency of extreme weather events, which have had a certain impact on society and the economy, people hope to achieve the goal of artificial weather intervention and better cope with meteorological disasters by conducting in-depth research on atmospheric physical processes and combining engineering technologies from multiple disciplines such as meteorology, physical chemistry, aeronautical science, and computer science. In order to achieve better results in weather modification operations, meteorological mission aircraft, with their real-time detection capabilities, powerful payload capacity, and stable and continuous operational capabilities, have gradually become a highly influential weather modification technology.

[0003] Meteorological mission aircraft typically comprise multiple complex systems, including detection subsystems, operational seeding subsystems, operational monitoring subsystems, air-to-ground communication subsystems, and integrated information subsystems. They carry various onboard equipment to adapt to different operational objectives. Therefore, this places higher demands on the integrated capabilities of airborne meteorological mission systems, particularly in areas such as integration and coordination, intelligent decision-making, mission scheduling, resource allocation, and conflict avoidance. Mission flights are generally completed collaboratively by multiple personnel. The airborne meteorological mission integrated system should be configured with different modes according to personnel responsibilities. This means supporting collaborative operation by multiple personnel, avoiding conflicts between different operators, and facilitating easy mode switching to adapt to dynamic adjustments in personnel responsibilities. Summary of the Invention

[0004] The purpose of this application is to provide a master-slave mode control method that supports multi-person collaborative operation, avoids conflicts between different people's operations, and facilitates mode switching.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a master-slave mode control method for an airborne meteorological mission integrated system, wherein the airborne meteorological mission integrated system includes a first display and control computer, a second display and control computer, a first detection subsystem and a first mission subsystem disposed on the first display and control computer, and a second detection subsystem and a second mission subsystem disposed on the second display and control computer, wherein the control method of the first display and control computer is the same as and performed simultaneously with the control method of the second display and control computer, and the method includes:

[0006] S1: Read the configuration file of the first display and control computer to obtain the default master-slave mode of the first display and control computer;

[0007] S2: The first display and control computer receives the heartbeat information from the second display and control computer via bus communication;

[0008] S3: Determine whether the current task integration system is in dual-machine working state based on whether the first display and control computer receives heartbeat information. If yes, proceed directly to S4. If no, set the master-slave mode of the first display and control computer to the default master-slave mode and send heartbeat information to the second display and control computer before returning to S2.

[0009] S4: Determine if it is the first judgment cycle. If yes, set the first display control computer to a master-slave mode that is mutually exclusive with the second display control computer, and proceed to S7; otherwise, the first display control computer receives the heartbeat information of the second display control computer through bus communication, and proceed to S5.

[0010] S5: Determine whether the first display control computer has received the master-slave mode switching command from the second display control computer. If yes, switch the master-slave mode of the first display control computer and proceed to S6. If no, proceed directly to S6.

[0024] When a display and control computer's task subsystem switches from "display mode" to "master control mode", the task integration software of that display and control computer reopens the data interface of the task subsystem, and the display and control computer communicates with external devices.

[0025] When the detection subsystem of a display and control computer switches from "master control mode" to "display mode", the task integration software of the display and control computer closes the interface for sending commands to the detection device;

[0026] When the detection subsystem of a display and control computer switches from "display mode" to "master control mode", the task integration software of the display and control computer opens the interface for issuing commands to the detection device.
