Description

Technical Field

[0001] This invention belongs to the field of flight control technology for avionics equipment, and specifically relates to a method and system for selecting control channels in a flight control system based on calendar priority. Background Technology

[0002] In a flight control system, the flight control computer is the core component, responsible for processing flight data, executing control algorithms, and outputting control commands. To ensure system reliability and redundancy, flight control systems typically employ a primary / backup (or redundant) configuration, meaning they are equipped with multiple flight control computers. One computer serves as the primary computer, responsible for the main flight control tasks, while the others act as backups. When the primary computer malfunctions or cannot function properly, the backup computers can quickly take over the control tasks, ensuring the safe flight of the aircraft.

[0003] The initial primary / backup selection strategy after the flight control computer (FNC) is powered on is crucial for ensuring the safe, stable, and efficient operation of the aircraft. When the flight control system is first activated after power-on, it is essential to ensure that the FNC computer in optimal condition and with the most stable performance is selected as the primary computer to handle flight control tasks. An inappropriate primary computer selection may lead to erroneous or missed flight control commands, potentially causing loss of control or a crash. When selecting the primary / backup FNC computer for the first time after power-on, it is also crucial to ensure that the selected primary computer can operate stably and work collaboratively with other system components. If the primary computer has performance instability or incompatibility issues with other systems, it may cause abnormal interruptions or malfunctions in the flight control system during flight, thereby affecting the aircraft's stability.

[0004] Common primary / standby selection strategies for flight control computers (FCCs) upon power-up include: default selection (priority selection), manual selection, and a combined selection strategy. The default selection (priority selection) strategy typically determines which FCC is the primary computer based on its installation location and preset priority. The manual selection strategy allows pilots or ground control personnel to manually select the primary / standby FCC based on actual conditions and needs, providing greater flexibility. The combined selection strategy can be customized and optimized according to different flight missions, aircraft types, and operating environments.

[0005] While the aforementioned common selection strategies can effectively achieve the initial primary / standby selection after the flight controller computer is powered on, they all have certain shortcomings. The default selection strategy (priority selection strategy) cannot dynamically adjust based on the current state of the flight controller computer, lacking flexibility, and a fixed default selection of the primary computer poses potential safety risks. Furthermore, a fixed default selection strategy can lead to an uneven usage frequency among the primary flight controller computers. The manual selection strategy relies on manual operation, increasing the risk of human error, and in emergency situations, it may fail to respond quickly and make correct decisions. A comprehensive selection strategy requires the integration and optimization of multiple selection methods, resulting in higher development difficulty and implementation complexity, and higher costs for maintenance and upgrades. Summary of the Invention

[0006] The purpose of this invention is to provide a method and system for selecting control channels in a flight control system based on calendar priority, so as to overcome the shortcomings of the prior art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: In a first aspect, the present invention provides a method for selecting control channels in a flight control system based on calendar priority, comprising: After the flight control system is powered on / reset, each flight control computer selects a control channel according to the power-on startup sequence, and the flight control computer corresponding to the selected control channel becomes the master flight control computer. When the flight control system receives the avionics transmission date, it reselects the control channel based on calendar priority, and the flight control computer corresponding to the reselected control channel becomes the master flight control computer. If the flight control system does not receive the avionics transmission date, it will retain the flight control computer selected in the power-on startup sequence as the master flight control computer.

[0008] Furthermore, after the flight control system is powered on / reset, each flight control computer selects a control channel according to the power-on startup sequence. The flight control computer corresponding to the selected control channel serves as the master flight control computer, including: For each flight control computer, control channels are acquired and relinquished based on self-declaration and self-revocation. If it finds that there is no control channel and it is valid, it declares itself as a control channel after waiting for the response time. If it finds that there are multiple control channels including itself and its own priority is not the highest among the multiple control channels, it revokes its self-declaration.

[0009] Furthermore, when the flight control system receives the avionics transmission date, it reselects the control channel based on calendar priority, including: If the calendar date is an odd number, the control channel is selected with the first fixed priority; if the calendar date is an even number, the control channel is selected with the second fixed priority.

[0010] Furthermore, the first fixed priority and the second fixed priority are preset priority orders among several flight control computers.

[0011] Furthermore, the number of flight control computers is two or three.

[0012] Furthermore, when reselecting the control channel, the first fixed priority and the second fixed priority of the two flight control computers are FCC1 > FCC2 and FCC1 < FCC2, respectively. The first and second fixed priorities of the three flight control computers are FCC1 > FCC2 > FCC3 and FCC2 > FCC1 > FCC3, respectively.

[0013] In a second aspect, the present invention provides a data rearrangement system accelerated by vector library matrix operation operators, comprising: The channel selection module is used to select the control channel according to the power-on startup sequence after the flight control system is powered on / reset. The flight control computer corresponding to the selected control channel becomes the master flight control computer. The reselection module is used by the flight control system to reselect the control channel based on calendar priority when it receives the avionics transmission date. The flight control computer corresponding to the reselected control channel becomes the main flight control computer. If the flight control system does not receive the avionics transmission date, it will retain the flight control computer selected in the power-on startup sequence as the master flight control computer.

[0014] Furthermore, when the flight control system receives the avionics transmission date, it reselects the control channel based on calendar priority, including: If the calendar date is an odd number, the control channel is selected with the first fixed priority; if the calendar date is an even number, the control channel is selected with the second fixed priority.

[0015] Thirdly, the present invention provides a computer device, including a memory, a storage device, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the steps of a flight control system control channel selection method based on calendar priority.

[0016] Fourthly, the present invention provides a computer-readable storage medium storing a computer program, which, when executed by a processor, implements the steps of the aforementioned method for selecting a control channel of a flight control system based on calendar priority.

Simultaneously, it balances the usage frequency of each flight control computer, increases the reliability history of each computer, and enhances the aircraft's safety, performance optimization capabilities, fault diagnosis and prevention capabilities, and data analysis and decision support capabilities.

[0029] Example 1, please refer to Figure 1 This invention provides a method for selecting control channels in a flight control system based on calendar priority, comprising: After the flight control system is powered on / reset, each flight control computer selects a control channel according to the power-on startup sequence, and the flight control computer corresponding to the selected control channel becomes the master flight control computer. When the flight control system receives the avionics transmission date, it reselects the control channel based on calendar priority, and the flight control computer corresponding to the reselected control channel becomes the master flight control computer. If the flight control system does not receive the avionics transmission date, it will retain the flight control computer selected in the power-on startup sequence as the master flight control computer.

[0030] This invention improves the flexibility of the initial primary / backup selection process after the flight control computer is powered on, without introducing manual operation, and without incurring additional development difficulties or maintenance and upgrade costs. Simultaneously, it balances the usage frequency of each flight control computer, increases the reliability history of each computer, and enhances the aircraft's safety, performance optimization capabilities, fault diagnosis and prevention capabilities, and data analysis and decision support capabilities.

[0031] Example 2: This invention provides a method for selecting control channels in a flight control system based on calendar priority, comprising: The technical problem to be solved by this invention is to propose a flight control system control channel selection method based on calendar priority, based on the existing priority selection strategy, to improve the flexibility of the first primary / backup selection process after the flight control computer is powered on without introducing manual operation, and without causing additional development difficulty and maintenance and upgrade costs.

[0032] A method for selecting control channels in a flight control system based on calendar priority is provided. This method is based on a priority selection strategy, and only flight control computers with valid channels can participate in the selection. The method includes the following steps: For each flight control computer, control channels are acquired and relinquished based on self-declaration and self-revocation. That is, if it finds that there is no control channel and it is valid, it declares itself as a control channel after waiting for the response time. If it finds that there are multiple control channels including itself and its own priority is not the highest among the multiple control channels, it should revoke its self-declaration.

[0033] After the system is powered on / reset, each flight control computer selects the control channel according to the power-on startup sequence.

[0034] If the aircraft is on the ground and receives the current date from the avionics system, it will force a calendar priority selection (i.e., if the current calendar date is odd, the control channel will be selected with fixed priority 1; if the current calendar date is even, the control channel will be selected with fixed priority 2) to select the control channel.

[0035] If the aircraft is on the ground and has not received the current date from the avionics system, the flight control computer selected in the power-on startup sequence will remain as the primary flight control computer.

[0036] Example 3: This invention provides a method for selecting control channels in a flight control system based on calendar priority, comprising: a. For each flight control computer, control channels are acquired and relinquished based on self-declaration and self-revocation. That is, if it finds that there is no control channel and it is valid, it declares itself as a control channel after waiting for the response time. If it finds that there are multiple control channels including itself and its own priority is not the highest among the multiple control channels, it should revoke its self-declaration.

[0037] b. After the system is powered on / reset, each flight control computer selects the control channel according to the power-on sequence.

[0038] c. If the aircraft is on the ground and receives the current date from the avionics system, force a calendar priority selection (i.e., if the current calendar date is odd, select the control channel with fixed priority 1; if the current calendar date is even, select the control channel with fixed priority 2) to select the control channel.

[0039] d. If the aircraft is on the ground and has not received the current date from the avionics system, the flight control computer selected in the power-on startup sequence shall remain as the primary flight control computer.

[0040] The present invention will now be described in further detail with reference to the accompanying drawings.

[0041] Step 1: After the system is powered on / reset, each flight control computer selects the control channel according to the power-on sequence.

[0042] Step 2: Determine if the current date has been received from the avionics system.

[0043] Step 3: If the aircraft is on the ground and receives the current date from the avionics system, a calendar priority selection is forcibly performed. If the current calendar date is odd, a control channel is selected using fixed priority 1 (FCC1>FCC2>FCC3); if the current calendar date is even, a control channel is selected using fixed priority 2 (FCC2>FCC1>FCC3). For each flight control computer, control channels are acquired and relinquished based on its own declaration and revocation. That is, if it finds that there is no control channel currently available and it is valid, it declares itself as a control channel after waiting for the response time. If it finds that there are multiple control channels, including itself, and its own priority is not the highest among the multiple control channels, it should revoke its own declaration.

[0044] Step 4: If the aircraft is on the ground and has not received the current date from the avionics system, the flight control computer selected in the power-on startup sequence will remain as the primary flight control computer.

[0045] Another embodiment of the present invention provides a data rearrangement system accelerated by vector library matrix operation operators, comprising: The channel selection module is used to select the control channel according to the power-on startup sequence after the flight control system is powered on / reset. The flight control computer corresponding to the selected control channel becomes the master flight control computer. The reselection module is used by the flight control system to reselect the control channel based on calendar priority when it receives the avionics transmission date. The flight control computer corresponding to the reselected control channel becomes the main flight control computer. If the flight control system does not receive the avionics transmission date, it will retain the flight control computer selected in the power-on startup sequence as the master flight control computer.
