Description

Technical Field

[0001] This application relates to the field of rockets, specifically to an integrated safety control method and system for launch vehicles. Background Technology

[0002] The launch vehicle safety control system is a component of the rocket's self-destruct control function, used to destroy the rocket if it deviates from its safe flight path. The general principle of a rocket safety control system is as follows: Figure 1 As shown, a safety command receiver is at its core. Upon receiving a remote control command, it outputs an external safety self-destruct signal. The control system, upon receiving this signal, executes the self-destruct sequence. In traditional safety systems centered on a safety command receiver, the safety system can only translate remote control commands sent from the ground and convert them into an external safety self-destruct signal, which is then output to the control system. The control system then executes the self-destruct sequence. The safety system's functional design is relatively simple. During rocket flight, due to the safety control strategy's tendency to protect the rocket, in extreme cases where the rocket's attitude becomes unstable, the control system may not trigger the attitude self-destruct signal before the rocket's structure suffers a destructive failure. This damages the power supply and signal lines of the safety command receiver. In this situation, the ground-based self-destruct signal cannot destroy the damaged rocket, posing a significant risk to personnel and property on the ground.

[0003] Therefore, how to provide an integrated launch vehicle safety control method to improve the reliability of the self-destruct safety system has become an urgent problem to be solved in this field. Summary of the Invention

[0004] This application proposes an integrated launch vehicle safety control system, including a safety control antenna, a safety control assembly, and a safety power supply unit; the safety control antenna is used to send remote control commands to the safety control assembly; The safety power supply unit is connected to the safety control assembly to provide the safety control assembly with primary power, including instrument power and pyrotechnic power. The safety control assembly is connected to both the safety control antenna and the safety power supply unit to receive remote control commands sent through the safety control antenna and to output self-destruct signals to the self-destruct device or self-destruct pyrotechnic device according to the remote control commands.

[0005] As mentioned above, the safety control unit also receives attitude self-destruct signals sent by the control system unit and outputs the self-destruct sequence to the self-destruct device or self-destruct pyrotechnic device.

[0006] As described above, the security control assembly includes a security command receiver, a radio frequency signal translation module, a self-destruct signal logic combination module, and a self-destruct timing control output module. The security command receiver is used to receive remote control commands from the security antenna and send the remote control commands to the radio frequency signal translation module. The radio frequency signal translation module is used to translate the remote control commands into self-destruct signals and send them to the self-destruct signal logic combination module. The self-destruct signal logic combination module is used to control the output of the self-destruct timing. The self-destruct timing control output module is used to receive the self-destruct timing and output the power supply from the pyrotechnic bus to the self-destruct device or self-destructing pyrotechnic item.

[0007] As shown above, the safety control unit simultaneously receives the attitude self-destruct signal output by the control system, and after passing through the self-destruct signal logic combination module, it also controls the output of the self-destruct timing sequence.

[0008] As mentioned above, the safety control assembly includes a pyrotechnic timing circuit test module, which connects to the self-destruct device or self-destructing pyrotechnic through a test switch.

[0009] As described above, during testing, the test switch closes to connect the circuit, and after the test, the test switch opens. This allows the self-destruct timing output circuit to be tested and the circuit resistance value to be obtained and fed back to the ground test system.

[0010] As shown above, the logic self-destruct module is an OR gate.

[0011] An integrated launch vehicle safety control method includes the following steps: receiving remote control commands; translating the remote control commands into self-destruct signals; and outputting the self-destruct signals to a self-destruct device or a self-destruct pyrotechnic device.

[0012] As mentioned above, this also includes receiving attitude self-destruct signals.

[0013] As mentioned above, this also includes performing self-testing of the timing circuit of pyrotechnic devices.

[0014] This application has the following beneficial effects: The integrated launch vehicle safety control method and system proposed in this application can operate autonomously. The execution of the self-destruct mechanism is completely independent of control or other systems, and it can independently complete the ground self-destruct command, thereby improving the reliability of the safety self-destruct system.

Detailed Implementation

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0019] The safety control system provided in this application has dedicated instrument power supply and pyrotechnic power supply. The safety control combination in the safety control system integrates modules such as safety control command receiver, radio frequency signal translation, self-destruct signal logic combination, self-destruct timing control output, and pyrotechnic timing loop self-test. It can independently complete external safety self-destruct output and complete functions such as pyrotechnic timing loop self-test during ground testing.

[0020] Example 1 like Figure 2 As shown, this application provides a safety control system, which includes a safety control antenna 210, a safety control assembly 220, and a safety power supply unit 230.

[0021] The security antenna 210 is used to send remote control commands to the security control assembly 220.

[0022] The safety power supply unit 220 is connected to the safety control assembly 230 and is used to provide the safety control assembly with a primary power supply, including instrument power supply and pyrotechnic power supply.

[0023] The safety control assembly 230 is connected to the safety control antenna 210 and the safety power supply unit 220 respectively, and is used to receive remote control commands sent through the safety control antenna 210, and output self-destruct signals to the self-destruct device or self-destruct pyrotechnics according to the remote control commands.

[0024] The safety control assembly 220 can also receive attitude self-destruct signals sent by the control system unit and output the self-destruct sequence to the self-destruct device or self-destruct pyrotechnic device.

[0025] Specifically, the security control assembly 220 includes a security control command receiver, a radio frequency signal translation module, a self-destruct signal logic combination module, a self-destruct timing control output module, and a pyrotechnic timing loop self-test module.

[0026] The security control command receiver receives the remote control radio frequency signal (remote control command) from the security control antenna.

[0027] After receiving the remote control radio frequency signal from the security control antenna, the security control command receiver sends the remote control radio frequency signal to the radio frequency signal translation module. The radio frequency signal translation module translates the remote control radio frequency signal into a self-destruct signal and sends it to the self-destruct signal logic combination module.

[0028] After the self-destruct signal passes through the self-destruct signal logic combination module (OR gate), it controls the output of the self-destruct timing sequence. After receiving the self-destruct timing sequence, the self-destruct timing sequence control output module outputs the power supply from the pyrotechnic bus to the self-destruct device or the self-destructing pyrotechnic item.

[0029] The safety control assembly can simultaneously receive the attitude self-destruct signal output by the control system, and after being combined with logic (OR gate), it can also control the output of the self-destruct timing.

[0030] Since the safety control assembly includes a pyrotechnic timing circuit test module, the pyrotechnic timing circuit test module connects to the self-destruct device or self-destructing pyrotechnic through a test switch.

[0031] During testing, the test switch closes to connect the circuit, and after the test is completed, the test switch opens. This allows the test to be completed on the self-destruct timing output circuit and the circuit resistance value to be obtained and fed back to the ground test system.

[0032] Example 2 like Figure 3 As shown, this application provides a design method for an integrated launch vehicle safety control system, which specifically includes the following steps: Step S310: Receive remote control command.

[0033] The security control command receiver receives the remote control radio frequency signal from the security control antenna.

[0034] Step S320: Translate the remote control command into a self-destruct signal.

[0035] After receiving the remote control radio frequency signal from the security control antenna, the security control command receiver sends the remote control radio frequency signal to the radio frequency signal translation module. The radio frequency signal translation module translates the remote control radio frequency signal into a self-destruct signal and sends it to the self-destruct signal logic combination module.

[0036] Step S330: Output the self-destruct signal to the self-destruct device or self-destruct pyrotechnic device.

[0037] After the self-destruct signal passes through the self-destruct signal logic combination module (OR gate), it controls the output of the self-destruct timing sequence. The self-destruct timing sequence control output module outputs the power supply from the pyrotechnic bus to the self-destruct device or the self-destructing pyrotechnic item.

[0038] This also includes receiving attitude self-destruct signals.

[0039] The safety control assembly can simultaneously receive the attitude self-destruct signal output by the control system, and after being combined with logic (OR gate), it can also control the output of the self-destruct timing.

[0040] This also includes conducting self-testing of the timing circuit of pyrotechnic devices.

[0041] The pyrotechnic timing circuit test module connects to the self-destruct device or self-destructing pyrotechnic through a test switch.

[0042] During testing, the test switch closes to connect the circuit; after testing, the test switch opens. This allows for the testing of the self-destruct timing output circuit and the acquisition of the circuit resistance value, which is then fed back to the ground testing system. The self-testing of the pyrotechnic timing circuit can also be performed during ground testing.

[0043] Although the examples referenced in this application are described for illustrative purposes only and not for limiting the scope of this application, changes, additions and / or deletions to the implementation may be made without departing from the scope of this application.

[0044] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
