Abstract
Description
Technical Field
[0001] This application relates to the field of cold missile launch control technology, and in particular to a wireless graded ignition device and ignition method for cold launch. Background Technology
[0002] Cold launch (also known as cold missile launch, missile ejection, or missile catapult) is a launch method that relies on the excitation tube of an external ejection system to generate power, propelling the missile away from the launch device and to a predetermined altitude before igniting the main engine. Before launch, the missile's flight trajectory and altitude need to be determined by controlling the launch angle and thrust.
[0003] Currently, the thrust of cold firing is mostly controlled by adjusting the specifications and quantity of the excitation tubes. One method, changing the excitation tube specifications to alter the thrust, requires modifying the parameters within the excitation tube during production. While this method allows for precise thrust control, it necessitates pre-production line modifications, which are difficult and time-sensitive. Furthermore, each parameter change necessitates the re-production of excitation tubes, rendering previously manufactured tubes unusable and resulting in resource waste. The method of controlling the number of excitation tubes to change the thrust is more immediate, allowing for immediate modification and avoiding resource waste and additional production line changes. However, this method offers a relatively fixed range of thrust options, lacking the precision to finely control the thrust magnitude. Summary of the Invention
[0004] Therefore, it is necessary to provide a wireless staged ignition device and ignition method for cold launch that has strong timeliness and high adjustment accuracy in changing the launch thrust, in order to address the above-mentioned technical problems.
[0005] A wireless staged ignition device for cold launch, the device comprising: a ground station, a launch timing controller, and a plurality of excitation tubes connected to the launch timing controller;
[0006] The ground station is used to set different ignition timing schemes and generate ignition timing control signals, and wirelessly transmits the ignition timing control signals to the transmission timing controller. The ground station includes host computer software and a P900 master radio. The host computer software is used to set different ignition timing schemes and generate ignition timing control signals, and wiredly transmits the ignition timing control signals to the P900 master radio. The P900 master radio is used to wirelessly transmit the ignition timing control signals to the transmission timing controller.
[0007] The launch timing controller receives and reads the ignition timing control signal transmitted from the ground station, and ignites the excitation tube in stages according to the ignition timing control signal. The launch timing controller includes a P900 slave radio, an integrated baseboard, relays, and a battery. The P900 slave radio receives the ignition timing control signal wirelessly transmitted from the P900 master radio and transmits it via wired connection to the integrated baseboard. The integrated baseboard is connected to the load of the excitation tube via a relay, and is used to read and perform staged control of the ignition timing of the excitation tube according to the ignition timing control signal. The battery is connected to the load of the excitation tube via a relay, and is used to ignite the excitation tube in stages according to the ignition timing under the control of the integrated baseboard. The relay provides connection between the integrated baseboard and the load of the excitation tube, and between the battery and the load of the excitation tube. When the relay is open, the battery is connected to the load of the excitation tube, providing ignition current; when the relay is closed, the battery is disconnected from the load of the excitation tube, stopping ignition.
[0008] Furthermore, the ground station and the launch timing controller also include an RS422 serial port cable;
[0009] In the ground station, the RS422 serial cable is used to transmit the ignition timing control signal to the P900 master radio via a wired connection between the host computer software and the P900 master radio. In the transmission timing controller, the RS422 serial cable is used to transmit the ignition timing control signal received by the P900 slave radio to the integrated backplane via a wired connection between the P900 slave radio and the integrated backplane.
[0010] Furthermore, the integrated baseboard includes a voltage conversion module, a TTL to 422 module, a TTL to 232 module, and a microcontroller;
[0011] The voltage conversion module is used to convert the voltage provided by the battery into the operating voltage of the microcontroller.
[0012] The TTL to 422 module is used to connect to the P900 radio via an RS422 serial cable, acquire the ignition timing control signal received by the P900 from the radio, convert the signal, and transmit the converted ignition timing control signal to the microcontroller via UART4 serial communication.
[0013] The TTL to RS232 converter module is used to connect to the reserved debugging serial port via an RS232 serial cable. It converts the debugging signal input through the reserved debugging serial port and then transmits the converted debugging signal to the microcontroller via USART2 serial communication.
[0014] The microcontroller is used to perform graded control of the ignition timing of the excitation tube by receiving the converted ignition timing control signal, and to perform debugging analysis by receiving the converted debugging signal.
[0015] Furthermore, the integrated baseboard also includes several PC ports and GND ports, with the number of PC ports matching the number of relays; the PC ports are connected to the positive terminal of the relays, and the GND ports are connected to the negative terminal of the relays.
[0016] Furthermore, the microcontroller in the integrated baseboard is also used to monitor the ignition of the excitation tube by automatically detecting the status of the PC port. When an abnormality is detected, the integrated baseboard generates an abnormal signal and sends it to the P900 slave radio. The P900 slave radio then wirelessly transmits the abnormal signal to the P900 master radio in the ground station. When the ground station receives the abnormal signal, it automatically stops the excitation tube from igniting.
[0017] Furthermore, the launch timing controller also includes a load indicator light. One end of the load indicator light is connected to the connection line between the PC port on the integrated baseboard and the positive terminal of the relay, and the other end is connected to the connection line between the GND port on the integrated baseboard and the negative terminal of the relay. The load indicator light is used to test and check whether the ignition signal is given normally. When the ignition signal is given normally, the load indicator light is lit; otherwise, the load indicator light is off.
[0018] Furthermore, the launch timing controller also includes a control switch, a load switch, and a fuse plug. The control switch is used to control the power supply to the integrated backplane; the load switch is used to control the load power supply to the excitation tube; and the fuse plug is used to short-circuit the load ends of the excitation tube.
[0019] Furthermore, the launch timing controller also includes a program indicator light, which is connected to the integrated baseboard and is used to indicate whether the ignition program is running normally. When the control switch is turned on, the program indicator light flashes for 0.5 seconds. After ignition is completed, the program indicator light stays on. If the program indicator light goes out or flashes abnormally, it indicates that there is a problem with the integrated baseboard.
[0020] Furthermore, the positive terminal of the battery in the launch timing controller is connected to the power input port on the integrated base plate through the control switch. The positive terminal of the battery is also connected to the positive terminal of the relay through the control switch and the load switch in sequence. The negative terminal of the relay is connected to the positive terminal of the load of the excitation tube to provide ignition for the excitation tube.
[0021] The negative terminal of the battery is connected to the GND port on the integrated base plate, the negative terminal of the fuse plug, and the negative terminal of the load of the excitation tube, respectively. The positive terminal of the fuse plug is connected to the connection line between the negative terminal of the relay and the positive terminal of the load of the excitation tube.
[0022] An ignition method based on the above-mentioned wireless graded ignition device for cold emission, the method comprising:
[0023] The ground station is set to send initial data to the transmission timing controller. After the P900 in the transmission timing controller receives the correct initial data from the radio, it sends a connection signal back to the P900 master radio in the ground station, thus establishing a wireless connection between the ground station and the transmission timing controller.
[0024] After the wireless connection is established, different ignition timing schemes are set in the host computer software of the ground station and ignition timing control signals are generated. The ignition timing control signals are then wirelessly transmitted to the transmission timing controller via the P900 main radio.
[0025] After receiving the ignition timing control signal from the radio, the P900 in the transmission timing controller enters the ready-to-transmit mode and feeds back the ready-to-transmit signal to the P900 main radio.
[0026] The P900 main radio receives the ready-to-transmit signals and feeds them back to the host computer software. It unlocks the ignition button on the host computer software and manually checks whether the transmission environment is normal.
[0027] If normal, click the ignition button on the host computer software and send an ignition signal to the P900 slave radio via the P900 master radio. After receiving the ignition signal, the P900 slave radio will ignite the excitation tube in stages according to the ignition timing control signal.
[0028] If an anomaly is detected, further determine whether to continue transmitting. If transmitting continues, the transmission timing controller exits the standby mode and re-receives the ignition timing control signal from the 900 main radio to enter standby mode again; otherwise, click the emergency stop button on the host computer software in the ground station to stop the excitation tube ignition program.
[0029] The aforementioned wireless staged ignition device and ignition method for cold emission have the following technical advantages:
[0030] 1. By setting the same ignition timing scheme and generating ignition timing control signals on the ground station, multiple excitation tubes can be ignited in stages according to the ignition timing set in the ignition timing control signals. There is no need to change the parameters or number of excitation tubes. The cold launch thrust can be precisely controlled simply by the different ignition timing of the excitation tubes. Moreover, the ignition timing set by the ground station can be accurate to the millisecond level, and the thrust adjustment is timely and highly accurate.
[0031] 2. Two P900 master and slave radios are used to realize long-distance wireless data transmission between the ground station and the transmission timing controller. The ignition of the excitation tube is remotely controlled through the ignition timing scheme set by the host computer software, which enables the test personnel to operate remotely throughout the cold launch process and ensures the safety of the test personnel.
[0032] 3. The transmission timing controller is equipped with a self-test function and can promptly provide feedback to the ground station via radio to ensure safety in case of transmission abnormalities. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0038] In one embodiment, it is assumed that three excitation tubes are required for cold emission, such as Figure 1 As shown, a wireless staged ignition device for cold launch is provided. The device includes: a ground station, a launch timing controller, and three excitation tubes connected to the launch timing controller.
[0039] The ground station is used to set different ignition timing schemes and generate ignition timing control signals, and wirelessly transmits these signals to the transmission timing controller. The ground station includes host computer software and a P900 master radio. The host computer software is used to set different ignition timing schemes and generate ignition timing control signals, and wiredly transmits these signals to the P900 master radio. The P900 master radio is used to wirelessly transmit the ignition timing control signals to the transmission timing controller. Specifically, the host computer software can be built using Visual Studio programming software. The interface of the host computer software built using Visual Studio is shown below. Figure 2 As shown, the ignition timing of the excitation tube is controlled by setting delay 1 and delay 2 in the host computer software and clicking "send parameter". Then, the ignition timing in the launch timing controller is read by clicking "read parameter".
[0040] The launch timing controller receives and reads the ignition timing control signal transmitted from the ground station, and ignites the three excitation tubes in stages according to the ignition timing control signal, such as... Figure 3 As shown, the transmission timing controller includes a P900 slave radio, an integrated baseboard, relays, and a battery. The P900 slave radio receives ignition timing control signals wirelessly transmitted from the P900 master radio and transmits them wired to the integrated baseboard. The integrated baseboard, connected to the relays, is then connected to the loads corresponding to the three excitation tubes, used to read and perform graded control of the excitation tube ignition timing according to the ignition timing control signals. The battery, connected to the relays, is then connected to the loads corresponding to the three excitation tubes, used to ignite the excitation tubes in stages according to the ignition timing under the control of the integrated baseboard. The relays provide connections between the integrated baseboard and the loads of the excitation tubes, and between the battery and the loads of the excitation tubes. When the relays are open, the battery is connected to the loads of the excitation tubes, providing ignition current; when the relays are closed, the battery is disconnected from the loads of the excitation tubes, stopping ignition. Specifically, a 3S battery is used.
[0041] Furthermore, the ground station and the launch timing controller also include an RS422 serial port cable;
[0042] In the ground station, the RS422 serial cable is used to transmit the ignition timing control signal to the P900 master radio via a wired connection between the host computer software and the P900 master radio. In the transmission timing controller, the RS422 serial cable is used to transmit the ignition timing control signal received by the P900 slave radio to the integrated backplane via a wired connection between the P900 slave radio and the integrated backplane.
[0043] Furthermore, the integrated baseboard includes a voltage conversion module, a TTL to 422 module, a TTL to 232 module, and a microcontroller;
[0044] The voltage conversion module is used to convert the voltage provided by the battery into the operating voltage of the microcontroller. Specifically, the voltage conversion module can be a DC12V to 5V module, which is used to convert the 12V voltage provided by the 3S battery into the 5V operating voltage of the microcontroller.
[0045] The TTL to 422 module is used to connect to the P900 radio via an RS422 serial cable, acquire the ignition timing control signal received by the P900 from the radio, convert the signal, and transmit the converted ignition timing control signal to the microcontroller via UART4 serial communication.
[0046] The TTL to RS232 converter module is used to connect to the reserved debugging serial port via an RS232 serial cable. It converts the debugging signal input through the reserved debugging serial port and then transmits the converted debugging signal to the microcontroller via USART2 serial communication.
[0047] The microcontroller is used to perform graded control of the ignition timing of the excitation tube by receiving the converted ignition timing control signal, and to perform debugging analysis by receiving the converted debugging signal. Specifically, the microcontroller can be an STM32H743.
[0048] Furthermore, the integrated baseboard also includes several PC ports and GND ports, with the number of PC ports matching the number of relays; the PC ports are connected to the positive terminal of the relays, and the GND ports are connected to the negative terminal of the relays.
[0049] Furthermore, the microcontroller in the integrated baseboard is also used to monitor the ignition of the excitation tube by automatically detecting the status of the PC port. When an abnormality is detected, the integrated baseboard generates an abnormal signal and sends it to the P900 slave radio. The P900 slave radio then wirelessly transmits the abnormal signal to the P900 master radio in the ground station. When the ground station receives the abnormal signal, it automatically stops the excitation tube from igniting.
[0050] Furthermore, the launch timing controller also includes a load indicator light. One end of the load indicator light is connected to the connection line between the PC port on the integrated baseboard and the positive terminal of the relay, and the other end is connected to the connection line between the GND port on the integrated baseboard and the negative terminal of the relay.

When the ignition signal is given normally, the load indicator light is lit; otherwise, the load indicator light is off.
[0051] Furthermore, the launch timing controller also includes a control switch, a load switch, and a fuse plug. The control switch controls the power supply to the integrated baseboard; the load switch controls the load power supply to the excitation tube; and the fuse plug short-circuits the load terminals of the excitation tube. The excitation tube load will not ignite if the fuse plug is not removed. During a formal launch, both the control switch and the load switch must be open, and the fuse plug must be removed for the excitation tube load to ignite and launch.
[0052] Furthermore, the launch timing controller also includes a program indicator light, which is connected to the integrated baseboard and is used to indicate whether the ignition program is running normally. When the control switch is turned on, the program indicator light flashes for 0.5 seconds. After ignition is completed, the program indicator light stays on. If the program indicator light goes out or flashes abnormally, it indicates that there is a problem with the integrated baseboard. At this time, the ignition test needs to be stopped and the equipment needs to be checked.
[0053] Furthermore, the positive terminal of the battery in the launch timing controller is connected to the power input port on the integrated base plate through the control switch. The positive terminal of the battery is also connected to the positive terminal of the relay through the control switch and the load switch in sequence. The negative terminal of the relay is connected to the positive terminal of the load of the excitation tube to provide ignition for the excitation tube.

[0057] Ground station connected: The ground station is set to send initial data to the transmission timing controller. After the P900 in the transmission timing controller receives the correct initial data from the radio, it sends a connection signal back to the P900 master radio in the ground station, thus establishing a wireless connection between the ground station and the transmission timing controller.
[0058] Timing settings: After the wireless connection is established, the host computer software in the ground station sets different ignition timing schemes and generates ignition timing control signals, and then wirelessly transmits the ignition timing control signals to the transmission timing controller through the P900 master radio.
[0059] Entering standby mode: After receiving the ignition timing control signal from the radio, P900 in the transmission timing controller enters the standby mode and feeds back the standby signal to the P900 main radio.
[0060] Human judgment of whether it is normal: The P900 main radio will feed back the received ready-to-transmit signal to the host computer software, unlock the ignition button of the host computer software, and manually judge whether the transmission environment is normal.
[0061] If normal, click the ignition button in the host computer software of the ground station and send the ignition signal to the P900 slave radio through the P900 master radio. After receiving the ignition signal, the P900 slave radio will ignite the excitation tube in stages according to the ignition timing control signal.
[0062] If an anomaly is detected, further determine whether to continue transmitting. If transmitting continues, the transmission timing controller exits the standby mode and re-receives the ignition timing control signal from the 900 main radio to enter standby mode again; otherwise, click the emergency stop button on the host computer software in the ground station to stop the excitation tube ignition program.

[0064] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
