Description

Technical Field

[0001] This utility model relates to the field of rocket propulsion control technology, specifically to a long-distance, multi-channel controllable rocket booster launch control device. Background Technology

[0002] In applications such as drones, rocket launches, and pyrotechnics control, launch controllers, as critical control devices, undertake the important tasks of ignition control and status monitoring of pyrotechnics (such as igniters and boosters). Currently, most launch controllers on the market are single-unit control devices with relatively limited functionality, capable of controlling only a single channel. They cannot meet the demands for multi-unit collaborative control and high reliability and safety under complex operating conditions. Especially in scenarios such as multi-unit formation and cluster launches, traditional launch controllers exhibit significant shortcomings in communication range, multi-channel control, safety, and fault diagnosis.

[0003] For example, some existing rocket launch controllers use wireless communication, but this communication range is limited and susceptible to interference, leading to control delays. Furthermore, existing rocket launch controllers have serious vulnerabilities in their misoperation protection mechanisms, lacking effective physical isolation and logical verification methods. Operators performing complex and high-risk operations may trigger misoperations due to fatigue, negligence, or misjudgment. Such misoperations not only cause significant economic losses but also affect the safety and reliability of the entire system. In addition, existing launch controllers are inadequate in battery management, fault diagnosis, and voltage detection, failing to monitor battery status accurately and in real time. This can lead to insufficient power during the rocket's flight phase, preventing the rocket from completing its intended mission at critical moments, or even causing flight failure. Moreover, the lack of effective fault warning and self-checking mechanisms means that when launch control fails, the cause of the failure is unknown. Utility Model Content

In summary, the above describes the specific implementation of this remotely controllable multi-channel rocket booster launch control device. I. Product Overview This remotely controllable multi-channel rocket booster launch control device (hereinafter referred to as "launch control device") is a specialized control device designed for rocket launch, multi-machine collaborative control, and other scenarios. It is mainly used for remote ignition control of rocket boosters. For status monitoring and fault diagnosis, the equipment adopts a separate design for the operation and launch control ends. It achieves stable communication within 800 meters via a frequency-hopping wireless communication module and supports at least eight independent launch control channels. This meets the needs of complex scenarios such as multi-rocket cluster launches and formation coordination. The core advantages of the equipment include: long-distance high-stability control: 800-meter wireless communication distance, strong anti-interference capability, ensuring control reliability in complex electromagnetic environments; multi-channel collaborative control: eight or more independent launch control channels, supporting simultaneous or time-sharing control of multiple rocket boosters; and multiple safety protections: a physical + logical dual-layer anti-accidental touch mechanism to avoid safety accidents caused by misoperation. Intelligent fault diagnosis: Real-time monitoring of channel voltage, battery status, communication quality, etc., generating clear fault codes and suggesting solutions. Dual battery pack guarantee: 29V / 68V dual voltage output, automatic switching, ensuring stable power supply under extreme conditions. The operating terminal is a user-controlled terminal with integrated core operating components, specifically: Power switch 4: Located on the left side of the operating terminal, a push-button design, used to turn the operating terminal power on / off. When on, display unit 9 lights up; when off, all functions stop operating. Unlock button 5: A red raised button with a physical protective cover to prevent accidental touches, used to unlock the ignition command. In the locked state, unlocking is required before ignition can be triggered. Ignition button 6: Green button, used to send ignition commands to the selected channel, only effective when unlocked and in "ignition mode". Test button 7: Blue button, used to check the connection status of the launch control channel and rocket booster in "test mode", without triggering actual ignition. Mode selection knob 8: Can rotate to switch between "test mode" and "ignition mode": Test mode: used for equipment self-test and booster connection status detection, only outputs detection signals and does not start ignition. Ignition mode: used for formal launch, can output ignition signals and trigger booster operation. Display unit 9: 2.A 4-inch LCD touchscreen displays the following information in real time: Equipment status: current mode test / ignition, communication status normal / interrupted; Parameter data: launch control voltage 29V / 68V, operating terminal battery voltage, resistance values ​​of each channel; Fault information: fault codes such as F.01, C.43, etc., and brief prompts; Channel status: selected channel number and corresponding status normal / abnormal; Channel selection keys: the number keys below the display unit correspond to channels 1-8, used to switch the launch control channel to be controlled. The launch control terminal is the execution terminal directly connected to the rocket booster, installed near the launch pad. Specific components are as follows: Launch control channel 10: at least 8 independent interfaces numbered 1-8, each corresponding to a rocket booster connection. The port and interface are labeled with channel numbers to ensure connection compatibility. Status indicator 11: Each channel has a three-color LED indicating its status: solid green: channel connection is normal, awaiting command; flashing yellow: channel is in test mode, receiving detection signals; solid red: channel fault such as abnormal voltage or loose connection; flashing green: ignition command executed, booster starts normally. Dual battery pack 12: Contains two built-in rechargeable batteries, outputting 29V battery 1 and 68V battery 2 voltages respectively, adapting to the voltage requirements of different rocket booster models. Battery status is transmitted in real-time to the operation terminal display unit. Automatic switching relay: Automatic switching device between the two battery packs; when the currently used battery voltage... When the voltage drops below 25V, it automatically switches to the other battery pack. During the switching process, the display unit will indicate "Battery Switching," which does not affect the continuity of control. Charging module 15: Type-C charging interface, located on the right side of the generator control unit, is used to charge the dual battery packs. The red indicator light next to the interface illuminates during charging and turns green when fully charged. Power switch 4: Main power control for the generator control unit. When turned on, the status indicator light flashes 3 times before entering standby mode. Unlock switch: A physical switch linked to the unlock button on the operating terminal, ensuring that the generator control unit can only receive ignition commands after the operating terminal is unlocked, forming a dual anti-accidental touch protection. It adopts frequency hopping wireless communication technology and is built into both the operating terminal and the generator control unit, requiring no manual operation and handling both. The system transmits signal commands, status data, and fault information between devices. The default communication distance is 800 meters, which may be shortened due to obstacles. Communication quality needs to be tested in advance. Integrated into the device, it monitors the following parameters in real time and generates fault codes: Channel voltage: Compares the ignition sampling voltage with the generator control voltage. If they are inconsistent, a channel fault is triggered, such as F.01-F.08. Communication status: If there is no signal transmission for 300ms, it is determined as a communication interruption, such as F.21, C.41. Battery voltage: When the generator control battery is below 25V or the operating battery is below 23V, a low battery alarm is triggered, such as F.22, C.42. Operation logic: If a misoperation is detected, such as when the test and ignition buttons are pressed simultaneously, a logic error is triggered, such as C.43. Site Requirements: The operating terminal must be placed in an open area within 800 meters of the launch point, avoiding large metal objects that could obstruct the communication signal and cause attenuation. The transmitter / control unit must be fixed to a stable platform next to the launch pad, secured with bolt 13 to prevent vibration from causing loosening. Electromagnetic Environment: Keep away from high-voltage power lines, radar stations, and other strong electromagnetic interference sources. If necessary, use an electromagnetic shield (optional accessory) to cover the transmitter / control unit to ensure stable communication. Weather Conditions: Operation is prohibited in severe weather conditions such as heavy rain, thunderstorms, or wind speeds ≥10m / s to prevent short circuits or rocket launch deviation. Visual Inspection: Inspect the operating terminal and transmitter / control unit casings for damage, loose buttons, and foreign objects such as dust and metal shavings on the interfaces. If any are found, clean them with a dry, soft cloth. Power Supply Inspection: Operating end: Press and hold the power switch for 43 seconds. After the display unit lights up, check the battery voltage. It should be ≥23V. If it is lower than 23V, it needs to be charged through the Type-C interface. During charging, it will display "Charging". When fully charged, it will display "Sufficient power". Transmission control end: Turn on the power switch and observe the dual battery pack voltage display unit. It will display "Battery 1 Voltage" and "Battery 2 Voltage" simultaneously. Both should be ≥25V. If it is lower than 25V, it needs to be charged through charging module 15. Prioritize charging the 29V battery, which is the default main power supply. Communication test: After both the operating end and the transmission control end are powered on, the "Communication" icon on the display unit should be solid green. If it flashes or turns red, the device position needs to be rearranged until communication is stable. You can send a signal through "Test Mode" to check the delay. The normal delay should be <100ms. Confirm that the launch control power supply is off. Connect the rocket booster ignition wires to launch control channel 10 according to their numbers: channel 1 to booster 1, channel 2 to booster 2, and so on. Ensure the plug is fully inserted and you hear a "click" sound. Tighten the fixing nut at the interface. After connecting, gently pull the wire to check for looseness. If the interface comes loose, reconnect it to avoid poor contact that could lead to ignition failure. Turn on the launch control and operating terminal power supplies in sequence. The launch control should be turned on first to ensure the communication module starts first. The operating terminal display unit will enter the self-test interface, displaying "Communication connection in progress," "Channel detection in progress," and "Battery status detection" in sequence. After completion, it will prompt "Self-test normal." If there is a fault, the corresponding code will be displayed directly. Troubleshooting should be performed according to the "Troubleshooting" section. Rotate the module. Select mode by turning knob 8 to "Test Mode" and pressing "Test Button 7". All status indicator lights 11 on the transmitter control end should flash yellow twice simultaneously, then return to solid green, indicating that the equipment hardware is normal. Channel selection: Press the "Channel Selection Key" on the operating terminal to select the channel to be tested, such as channel 1. The display unit will simultaneously display "Current Channel: 1". Parameter setting: Touch the "Transmitter Control Voltage" option on the display unit and select the test voltage of 29V or 68V, which must be consistent with the booster's rated voltage. Send test command: Press "Test Button 7". The operating terminal will display "Testing...", and the status indicator light 11 of the corresponding channel on the transmitter control end will turn yellow and flash. At the same time, the display unit will update the "Channel Resistance Value" in real time. The normal range must be consistent with the booster's instruction manual, such as 1.5-3Ω, Result Judgment: If "Test Normal" is displayed and the indicator light returns to green, it means the channel and booster connection is normal. If "F.01" is displayed indicating a voltage error in Channel 1, check if the booster wiring is loose or the model is incompatible. Reconnect and test again. Repeat the operation: Test all channels that need to be used at least twice according to the above steps to ensure consistent results. Unused channels can be skipped, but their status must be confirmed as "Not Enabled". Mode Switching: Rotate the mode selection knob 8 to "Ignition Mode". The display unit will prompt "Please confirm the ignition mode, do not operate incorrectly". Press the "Confirm" key to enter. Channel and Voltage Confirmation: Select the target channel, such as Channel 1, and confirm the "Generator Control Voltage" on the display unit. The voltage should be consistent with the booster's rated voltage of 29V or 68V. If inconsistent, touch the "Generator Control Voltage" switch and wait 5 seconds for the system to adjust the output. Unlocking operation: Open the physical protective cover of unlock button 5, press and hold the unlock button for 3 seconds. The display unit will indicate "Unlocked, ignition ready." Simultaneously, the generator control end unlock switch will activate to release the mechanical lock. Ignition command transmission: Confirm that there are no personnel in the vicinity of the launch warning range, press "Ignition button 6." The operating terminal will display "Ignition command sent." The status indicator light 11 of the corresponding channel on the generator control end will flash green 3 times and then remain on, indicating successful ignition. Status feedback: Within 10 seconds after ignition, the display unit will receive the "Ignition feedback" signal from the generator control end and indicate "Ignition successful." "Channel 1 complete". If there is no feedback within 10 seconds, "Ignition not confirmed" will be displayed. The status of the transmitter control end must be checked immediately; it may be due to a fuse protection trigger. See the fault handling section. Follow the "Test Mode" procedure to complete the test of all channels to be launched, ensuring they are all "normal". Switch the operating terminal to "Ignition Mode". Press the "Channel Selection" key to select the channels to be launched in sequence, such as channels 1-4. Press the "Batch Selection" key to confirm. The display unit will indicate "Channels 1-4 selected". Confirm that the transmitter control voltage is consistent. If the channel voltages are different, they need to be launched in batches. After unlocking, press and hold the ignition button for 5 seconds to initiate the batch ignition command. The status indicator lights for channels 1-4 on the transmitter control end will flash green simultaneously. After completion, a "Batch ignition successful" message will be simultaneously displayed. If a certain channel fails to ignite... If a fire failure occurs, such as channel 3 displaying "F.03", subsequent operations must be stopped immediately. Troubleshoot according to the fault handling procedure. After troubleshooting, launch that channel separately. After all rockets have been launched, first turn off the power to the launch control terminal, then turn off the power to the operating terminal to avoid residual voltage damaging the equipment. Disconnect the rocket booster from the launch control channel, organize and coil the wires for storage, clean the equipment surface, and check the interfaces for burn marks. If any are found, lightly sand them with fine sandpaper before use. Then, place the equipment in a dedicated protective box for moisture and shock protection. Equipment faults are indicated by fault codes displayed on the display unit. The specific handling methods are as follows: Code meaning: F.01 corresponds to an error in the sampling voltage of channel 1. The ignition sampling voltage is inconsistent with the launch control voltage. F.02-F.08 corresponds to channels 2-8, and so on. Possible causes: loose booster wiring, channel interface oxidation, abnormal output voltage at the transmitter / controller end. To troubleshoot, turn off the transmitter / controller end power, unplug and replug the booster wiring for the corresponding channel, wipe the interface with an alcohol swab to remove the oxide layer, restart the device and enter test mode, and check the channel voltage. If the error persists, replace the transmitter / controller end; it may be due to an internal pressure sensor malfunction. F.21 indicates no signal received by the transmitter / controller end for 300ms; C.41 indicates no signal received by the operator end for 300ms. Possible causes: distance exceeding 800 meters, electromagnetic interference, or obstruction of equipment location. Interference source, troubleshooting steps: Confirm the distance between the operating end and the transmitter / controller is ≤800 meters. Remove obstructions such as metal plates or large equipment. Restart the communication module and simultaneously press and hold the "Communication" button on both the operating end and the transmitter / controller for 5 seconds. Retest the communication status. If the interference occurs frequently, replace the standard accessories of the spare communication module and record the location of the interference source to avoid in the future. Code meaning: F.22 indicates that the transmitter / controller's battery 1 is <25V, F.23 indicates that the transmitter / controller's battery 2 is <25V, C.42 indicates that the operating end's battery is <23V. Troubleshooting steps: Immediately stop operation and connect the charger to the corresponding battery. The generator control unit prioritizes charging battery 1. The operating unit must be powered off for charging. In emergencies, the generator control unit battery can be manually switched to a fully charged battery via the "Battery Switching" option on the display unit. Batteries stored for a long time should be recharged to 80% capacity once a month to avoid depletion and lifespan reduction. Code meanings: C.43 indicates simultaneous operation of the test and ignition buttons, or a mismatch between mode and command, such as pressing the ignition button in test mode. C.44 indicates pressing the ignition button without unlocking. Handling steps: Release all buttons, wait 5 seconds, and then operate again. Strictly follow the "unlock first, then..." command. If the "re-ignition" and "mode and command matching" rules are frequently triggered, check if the button is stuck. Wipe the button contacts with an alcohol swab. Replace the button module if necessary. Symptom: After ignition, the channel indicator light is constantly red, and there is no feedback from the generator control end. Possible cause: The channel current exceeds 5A. If the booster is short-circuited, the fuse protection device will automatically disconnect the circuit. Handling steps: Turn off the generator control end power. Replace the fuse protection device for the corresponding channel. Use a fuse of the same specification, such as 5A / 250V. Check if the booster is short-circuited. Measure the resistance with a multimeter. If it is short-circuited, the resistance value is <0.5Ω, try again after replacing the faulty booster. Cleaning: Wipe the surface of the operating end and the generator control end with a dry, soft cloth. Blow away dust from the interface with compressed air. Do not rinse directly with water or detergent. Connection check: Check all wires for damage or breakage, and check the interface for deformation. If any are found, replace the wires with high-temperature resistant wires with a temperature resistance ≥125℃. Parameter recording: Record the usage time, channel status, and fault codes in the equipment logbook if applicable, for easy problem tracing. Environmental requirements: Store in a dry, ventilated indoor environment at a temperature of -10℃ to 40℃ and a relative humidity ≤60%. Keep away from corrosive gases such as acid and alkali mists. Battery handling: Charge all batteries to 80% capacity and store them separately from the equipment to avoid leakage and corrosion. Recharge every 3 months. Packaging protection: Wrap the operating end and generator control end in an anti-static bag and place them in a dedicated protective box. Place a desiccant in the box and replace it monthly. Voltage calibration: Use a standard voltmeter to test the output voltage of the generator control end at 29V / 68V. The error must be ≤ ±0.5V; contact the manufacturer for calibration if this limit is exceeded. Communication calibration: Use a signal tester to check the packet loss rate within an 800-meter distance; it must be ≤0.1%. If this limit is exceeded, adjusting the communication module frequency requires professional personnel. Operation qualifications: Operators must undergo professional training and be familiar with the equipment functions and rocket launch procedures. Unlicensed operation is strictly prohibited. Operation procedures: Strictly follow the sequence of "Test → Confirm → Unlock → Ignition." Skipping tests and directly igniting is prohibited. Playing or answering phone calls during operation is prohibited to avoid distraction and misoperation. Emergency handling: In case of accidental ignition (e.g., accidental triggering), immediately press the large red "Emergency Stop" button on both the operating and launch control terminals to cut off all outputs. Modification is prohibited: Unauthorized disassembly of the equipment casing or replacement of non-original parts such as fuses or batteries is strictly prohibited, as this may lead to equipment failure or safety accidents. Disposal: After the equipment reaches its service life, it is recommended to contact the manufacturer for recycling. Discarding electronic components and batteries indiscriminately is prohibited; environmentally friendly dismantling is required.
