A mutual backup weapon emergency abandonment control system

Abstract

The present invention discloses a weapon emergency abandonment control system that backs up each other. First, the components with the weapon emergency abandonment control function are designed as double backups. Each component has a PANIC module responsible for completing the emergency abandonment of the weapon. Each PANIC module completes the emergency abandonment function of the main weapon of the single-side hanging point and the emergency abandonment function of the backup weapon of the opposite-side hanging point, ensuring that when a single hanging point failure occurs in the main weapon emergency abandonment function, the backup weapon emergency abandonment function can still smoothly complete the weapon emergency abandonment task as expected; secondly, the emergency power supply is divided into two levels of power supply, the first level is controlled by FPGA to generate a controlled emergency power supply, and the second level is divided into left and right hanging points and uses 2 independent power supplies to avoid the loss of the weapon emergency abandonment function due to the emergency power supply problem; finally, the weapon emergency abandonment output result is monitored by the recovery circuit. The present invention can ensure safe and reliable control of weapon emergency abandonment.

Description

Technical Field

[0001] The invention belongs to the technical field of aircraft hanging object management, and in particular relates to a weapon emergency abandonment control system. Background Art

[0002] Emergency jettisoning is a function that requires emergency jettisoning of weapons carried by the attachment point when the attachment management system fails and normal weapon jettisoning and firing cannot be carried out, or when an emergency occurs. Normally, an aircraft's weapon emergency jettisoning function is equipped with a component, and the component contains a set of independent module circuits to implement the weapon emergency jettisoning function. Each attachment point has a corresponding knob. For example, when the knob is selected at 1, it is necessary to perform emergency jettisoning on the weapon at attachment point 1, and the same applies to other attachment points. When the weapon emergency jettisoning function needs to be enabled in an emergency, after the aircraft provides emergency power supply, select the knob to the number corresponding to the target attachment point, and then cooperate with the logical interlocking and software control conditions to realize the emergency jettisoning of weapons at the target attachment point.

[0003] Since electronic components have a certain failure rate, and the circuit cross-linking relationship on the aircraft is complex, when other functional circuits are abnormal, it is possible that overcurrent will flow to the weapon emergency jettison function circuit, burning related electronic components. Regardless of any of the above situations, if a single point failure occurs in the control circuit corresponding to a certain hanging point, it is possible that the emergency jettison function of the weapon at that hanging point will fail, resulting in serious consequences such as the weapon cannot be jettisoned when it is needed, or the weapon is mistakenly jettisoned when it is not needed. Summary of the invention

[0004] In order to overcome the deficiencies of the prior art, the present invention provides a weapon emergency abandonment control system that backs up each other. First, the components with the weapon emergency abandonment control function are designed as double backups. Each component has a PANIC module responsible for completing the weapon emergency abandonment. Each PANIC module completes the main weapon emergency abandonment function of the single-side hanging point and the backup weapon emergency abandonment function of the opposite-side hanging point, ensuring that when a single hanging point failure occurs in the main weapon emergency abandonment function, the backup weapon emergency abandonment function can still smoothly complete the weapon emergency abandonment task as expected; secondly, the emergency power supply is divided into two levels of power supply, the first level is controlled by FPGA to generate a controlled emergency power supply, and the second level is divided into left and right hanging points and uses 2 independent power supplies to avoid the loss of the weapon emergency abandonment function due to the emergency power supply problem; finally, the weapon emergency abandonment output result is monitored by the recovery circuit. The present invention can ensure safe and reliable weapon emergency abandonment control.

[0005] The technical solution adopted by the present invention to solve the technical problem is as follows:

[0006] A mutually backed-up weapon emergency abandonment control system comprises a component 1, a component 2 and a plurality of hanging points, each component comprises a PANIC module for realizing a weapon emergency abandonment control function, and the software and hardware designs of the component 1 and the component 2 are completely the same;

[0007] The PANIC module in component 1 completes the main control function of emergency weapon abandonment for all odd-numbered hanging points and the backup control function of emergency weapon abandonment for all even-numbered hanging points; the PANIC module in component 2 completes the main control function of emergency weapon abandonment for all even-numbered hanging points and the backup control function of emergency weapon abandonment for all odd-numbered hanging points;

[0008] The emergency power supply of components 1 and 2 is controlled at two levels. The first level is implemented by FPGA control in each component. The emergency power supply is started only when the emergency function is needed. When it is not needed, the emergency power supply is always in the off state.

[0009] The PANIC modules in component 1 and component 2 are responsible for the second-level control of the emergency power supply of their respective components. After adding a protection circuit to the controlled emergency power supply generated by the first-level emergency power supply control, two emergency power supplies are independently supplied. When one of the emergency power supplies fails, the other emergency power supply completes the power supply function;

[0010] The weapon emergency abandonment control system adopts a key signal veto mechanism. The key signal is at the highest priority of condition judgment. When a key signal is collected, even if other conditions are met, the weapon emergency abandonment function is still not allowed to be executed;

[0011] The weapon emergency abandonment control system collects the weapon emergency abandonment output through an optical coupler and monitors the weapon emergency abandonment output result;

[0012] Furthermore, the critical signal is a no-shooting signal.

[0013] Furthermore, the weapon emergency jettisoning control system includes 12 hanging points, all odd-numbered hanging points refer to the 6 hanging points 1 / 3 / 5 / 7 / 9 / 11, and all even-numbered hanging points refer to the 6 hanging points 2 / 4 / 6 / 8 / 10 / 12.

[0014] The beneficial effects of the present invention are as follows:

[0015] The present invention solves the problem of failure of weapon emergency abandonment mission caused by single point failure during the weapon emergency abandonment process, and can ensure safe and reliable control of weapon emergency abandonment. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 This is a schematic diagram of the primary and backup control of the dual backup component weapon emergency abandonment of the present invention.

[0017] Figure 2This is a schematic diagram of the two-level control of emergency power supply of the present invention. DETAILED DESCRIPTION

[0018] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0019] In order to solve the problem of failure of weapon emergency abandonment function caused by single point failure, the present invention proposes a high-reliability weapon emergency abandonment control design with mutual backup to ensure safe and reliable weapon emergency abandonment control.

[0020] A mutually backed-up weapon emergency abandonment control system comprises a component 1, a component 2 and a plurality of hanging points, each component comprises a PANIC module for realizing a weapon emergency abandonment control function, and the software and hardware designs of the component 1 and the component 2 are completely the same;

[0021] The PANIC module in component 1 completes the main control function of emergency weapon abandonment for all odd-numbered hanging points and the backup control function of emergency weapon abandonment for all even-numbered hanging points; the PANIC module in component 2 completes the main control function of emergency weapon abandonment for all even-numbered hanging points and the backup control function of emergency weapon abandonment for all odd-numbered hanging points;

[0022] The emergency power supply of components 1 and 2 is controlled at two levels. The first level is implemented by FPGA control in each component. The emergency power supply is started only when the emergency function is needed. When it is not needed, the emergency power supply is always in the off state.

[0023] The PANIC modules in component 1 and component 2 are responsible for the second-level control of the emergency power supply of their respective components. After adding a protection circuit to the controlled emergency power supply generated by the first-level emergency power supply control, two emergency power supplies are independently supplied. When one of the emergency power supplies fails, the other emergency power supply completes the power supply function;

[0024] The weapon emergency abandonment control system adopts a key signal veto mechanism. "No firing" is the key signal with the highest priority in condition judgment. When a key signal is collected, even if other conditions are met, the weapon emergency abandonment function is still not allowed to be executed;

[0025] The weapon emergency abandonment control system collects the weapon emergency abandonment output through an optical coupler and monitors the weapon emergency abandonment output result; Specific embodiment:

[0027] When the pilot needs to safely and reliably jettison the weapon carried on the hanging point during combat or training, or when the weapon cannot be launched normally or special circumstances occur, the pilot can perform the following operations:

[0028] Emergency power is provided on board to power two components that back up each other;

[0029] The two components that back up each other are both designed with FPGA control circuits that control the power-on of the emergency module. By making the relevant control conditions effective, the PANIC module in the component is supplied with controlled emergency power.

[0030] like Figure 1 As shown, the PANIC module in component 1 completes the main control function of the weapon emergency abandonment of the six hanging points 1 / 3 / 5 / 7 / 9 / 11 and the backup control function of the weapon emergency abandonment of the six hanging points 2 / 4 / 6 / 8 / 10 / 12, and the PANIC module in component 2 completes the main control function of the weapon emergency abandonment of the six hanging points 2 / 4 / 6 / 8 / 10 / 12 and the backup control function of the weapon emergency abandonment of the six hanging points 1 / 3 / 5 / 7 / 9 / 11;

[0031] like Figure 2 As shown, the emergency power supply is controlled at two levels. The first level is implemented by the FPGA control in each component to ensure that the emergency power is always in a controlled state. The emergency power is only started when the emergency function is needed. When it is not needed, the emergency power is always in a shut-off state.

[0032] like Figure 2 As shown, the PANIC module in a single component is responsible for the second-level control of the emergency power supply. After adding a protection circuit to the controlled emergency power generated by the first-level emergency power supply control, it is divided into two independent power supplies. When one of the emergency power supplies fails, the other emergency power supply can ensure that the corresponding function is successfully completed without being affected.

[0033] The critical signal veto mechanism is adopted. The critical signal is at the highest priority of condition judgment. When the critical signal is collected, the weapon emergency jettison function is still not allowed to be executed even if other conditions are met.

[0034] The weapon emergency abandonment output is collected through optical coupling and the weapon emergency abandonment output result is monitored.
