[0002] Pursuing extremely high object motion speeds has always been an important direction of science and technology. From the perspective of the energy source for launch, so far, human society has gone through three stages: mechanical energy launch, chemical energy launch, and electromagnetic energy launch. Electromagnetic launch refers to a launch method that includes electromagnetic energy. Its emergence is an inevitable result of the integration of electrification and the transformation of electrical energy. With advantages such as cleanliness, high efficiency, sustainability, pollution-free, and ultra-high speed, electromagnetic launch technology will have broad application prospects in many fields such as aerospace, transportation, scientific research, and national defense and military.

It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0045] In one embodiment, Figure 1 Schematic structural diagram of an electromagnetic launch system provided by an embodiment of the present invention. This embodiment is applicable to the situation of accurately controlling the launch speed of the current projectile to be launched and improving the concealment and hit rate. As Figure 1 shown, the system includes: a control module 1, a multi-stage energy storage module 2, a multi-stage electromagnetic launch module 3, and an electromagnetic launch track 4; the number of stages of the energy storage module 2 is the same as that of the electromagnetic launch module 3; each electromagnetic launch module 3 is sequentially sleeved outside the electromagnetic launch track 4; an initial launch position is provided on the electromagnetic launch track 4; the energy storage module 2 is electrically connected to the electromagnetic launch module 3 and is used to discharge the stored electric energy to the electromagnetic launch module 3 so that the electromagnetic launch module 3 provides power for launching the current projectile 5; the control module 1 is electrically connected to the electromagnetic launch module 3 and is used to determine the number of stages of the electromagnetic launch module 3 to be turned on so that the turned-on electromagnetic launch module 3 provides power for the current projectile 5 and propels the current projectile 5 to be launched from the initial launch position on the electromagnetic launch track 4.

[0046] Among them, the energy storage module 2 is used to store electric energy and provide power to the electromagnetic launch module 3 through discharging. The energy storage module 2 may include, but is not limited to, at least one energy storage capacitor. The electromagnetic launch module 3 is a structure that converts electric energy into electromagnetic force to achieve the accelerated launch of the current projectile 5. In this embodiment, both the energy storage module 2 and the electromagnetic launch module 3 are multi-stage structures, and the number of stages of the energy storage module 2 is the same as that of the electromagnetic launch module 3, so that the electric energy stored in each stage of the energy storage module 2 can be discharged into the corresponding stage of the electromagnetic launch module 3. Additionally, Figure 1 By arranging the electromagnetic launch modules 3 on both sides of the electromagnetic launch track 4, it is exemplarily shown that the electromagnetic launch modules 3 are successively sleeved around the periphery of the electromagnetic launch track 4, and there is a preset distance between the electromagnetic launch modules 3. In actual setting, each stage of the electromagnetic launch modules 3 can be directly wound around the periphery of the electromagnetic launch track 4. Generally, the arrangement direction of the electromagnetic launch modules 3 is parallel to the axial direction of the electromagnetic launch track 4, so that the current projectile 5 can achieve step-by-step acceleration when launched from the initial launch position of the electromagnetic launch track 4 and finally reach the preset launch speed. The electromagnetic launch track 4 is a device that uses electromagnetic energy to replace traditional mechanical energy or chemical energy for launching. It conducts contact feeding through a linear guide rail and uses electromagnetic force to push the current projectile 5 to accelerate within the track. The control module 1 is the core control structure of this system and is used to determine the number of stages of the electromagnetic launch module 3 to be turned on and control the corresponding electromagnetic launch modules 3 to be turned on in sequence, so that the electric energy in the energy storage module 3 can provide forward power for the current projectile 5 through the turned-on electromagnetic launch modules 3, thereby pushing the current projectile 5 to be launched from the initial launch position on the electromagnetic launch track 4.

[0047] Specifically, when controlling the launch speed of the current projectile 5 to accurately reach the preset launch speed when the current projectile 5 exits the electromagnetic launch track 4, by electrically connecting the same-stage energy storage module 2 and the electromagnetic launch module 3, and the control module 1 is electrically connected to each electromagnetic launch module 3. After each stage of the energy storage module 2 is fully charged or the electric energy reaches a certain value, the control module 1 will determine the number of stages of the electromagnetic launch module 3 that need to be turned on to make the current projectile 5 reach the preset launch speed, and control the corresponding number of stages of the electromagnetic launch module 3 to be turned on in sequence. At this time, the electric energy stored in the energy storage module 2 will provide accelerating power for the current projectile 5 through the turned-on electromagnetic launch modules 3 in sequence, convert the electric energy into electromagnetic force, push the current projectile 5 to be launched from the initial launch position on the electromagnetic launch track 4 under the action of the electromagnetic force, and exit the electromagnetic launch track 4 at this speed to be launched to the target object to improve the hit rate.

[0048] It can be understood that the control module 1 controls the activation of each level of the electromagnetic emission module 3 in sequence. For example, if the total number of levels of the electromagnetic emission module 3 is 10, and the control module 1 determines that 3 levels of the electromagnetic emission module 3 need to be activated. At this time, before activating the first 3 levels of the electromagnetic emission module 3, the control module first controls the activation of the first-level electromagnetic emission module 3. After activation, the current projectile 5 is accelerated from the initial launch position under the action of the activated first-level electromagnetic emission module 3. When the current projectile 5 reaches the preset position, the control module controls the activation of the second-level electromagnetic emission module 3 to achieve continuous acceleration of the current projectile 5. After the second-level electromagnetic emission module 3 is activated for a certain period of time, the control module controls the first-level electromagnetic emission module 3 to turn off. Similarly, after the current projectile 5 is launched to the preset position on the electromagnetic emission track 4 surrounded by the second-level electromagnetic emission module 3, the control module 1 controls the activation of the third-level electromagnetic emission module 3. After the current projectile 5 runs for a certain period of time, the control module controls the second-level electromagnetic emission module 3 to turn off, so that the current projectile 5 is launched under the acceleration of the third-level electromagnetic emission module 3. After reaching the preset launch speed, the control module 1 controls the third-level electromagnetic emission module 3 to turn off, so that the current projectile 5 is launched at a constant speed at the current preset launch speed until it exits from the electromagnetic emission track 4.

[0049] In the technical solution of the embodiment of the present invention, by electrically connecting the energy storage module of the same level to the electromagnetic emission module and the control module to each electromagnetic emission module, after the energy storage module of each level is stored, the control module will determine the number of levels that the electromagnetic emission module needs to be activated to make the launch speed of the current projectile reach the preset launch speed, and control the activation of the corresponding levels of the electromagnetic emission module. At this time, the electric energy stored in the energy storage module will provide the power for the current projectile to accelerate forward in sequence through the activated electromagnetic emission module, and promote the current projectile to be launched from the initial launch position on the electromagnetic emission track to reach the preset launch speed. Using the above system, by the control module determining the number of levels of the electromagnetic emission module to be activated, the current projectile is launched under the action of electromagnetic force, which improves the concealment while ensuring that the current projectile accurately reaches the preset launch speed, realizes precise control of the launch speed, improves the hit rate of the projectile, and reduces the maintenance cost.

[0050] In another specific embodiment, optionally, Figure 2 is the structural schematic diagram of the second electromagnetic emission system provided by the embodiment of the present invention. Refer to Figure 2As shown, the electromagnetic emission module 3 includes a driving unit 31 and electromagnetic coils 32. Each electromagnetic coil 32 is successively sleeved around the periphery of the electromagnetic emission track 4; the control module 1 is electrically connected to each driving unit 31, and in the same stage, the energy storage module 2 is electrically connected to the electromagnetic coil 32 through the driving unit 31; the control module 1 is used to determine the number of stages for which the driving unit 31 is closed, and control the driving unit 31 to be closed successively, so that the electric energy stored in the energy storage module 2 is discharged to the electromagnetic coil 32 successively through the closed driving unit 31, providing power for the current projectile 5 and pushing the current projectile 5 to be launched from the initial launch position on the electromagnetic emission track 4.

[0051] Among them, the driving unit 31 is a bridge connecting the energy storage module 2 and the electromagnetic coil 32. When the driving unit 31 is closed, the electric energy stored in the energy storage module 2 is transmitted to the electromagnetic coil 32 through the closed driving unit 31, generating an electromagnetic force. In this embodiment, the driving unit 31 may include, but is not limited to, a switch. The electromagnetic coil 32 is a device that uses the principle of electromagnetic induction to accelerate the projectile. Its core is to generate a magnetic field through a current-carrying coil, and then use the interaction force between the magnetic field and the projectile to achieve acceleration. And, the current projectile 5 is usually a conductor and can be accelerated under the action of the electromagnetic force.

[0052] Specifically, when the control module 1 determines the number of stages for which the electromagnetic emission module 3 is turned on, it is essentially determining the number of stages for which the driving unit 31 in the electromagnetic emission module 3 is closed. After determining the number of stages for which the driving unit 31 is closed, the control module 1 controls the driving unit 31 to be closed successively, so that the electric energy stored in each stage of the energy storage module 2 is transmitted to the electromagnetic coil 32 through the corresponding closed driving unit 31. The electromagnetic coil 32 generates a magnetic field under the action of the electric energy, forming an electromagnetic force, and the electromagnetic force will accelerate the speed of the current projectile 5 transmitted in the electromagnetic emission track 4, so as to uniformly exit from the electromagnetic emission track 4 after reaching the preset launch speed.

[0053] Optionally, Figure 3 is a schematic structural diagram of the third electromagnetic emission system provided by the embodiment of the present invention. Figure 4 is a schematic structural diagram of a set of working timings provided by the embodiment of the present invention. Refer to Figure 3 and Figure 4 As shown, the system further includes a mode selection module 6; the mode selection module 6 is electrically connected to the control module 1; the control module 1 is further used to determine at least one set of working timings of the current projectile 5 according to different modes selected by the user and output them, so as to determine the number of stages for which the driving unit 31 is closed according to the working timings. A set of working timings includes a plurality of pulse signals, each pulse signal is used to control the on / off of one stage of the driving unit 31, and the number of pulse signals in a set of working timings is the same as the number of stages for which the driving unit 31 is closed.

[0054] Among them, the mode selection module 6 is a button key or a touch key for the user to make selections, realizing the interaction between the system and the user. In this embodiment, the mode selection module 6 may include multiple different keys, such as a speed gear selection key, an insurance mode key, a firing mode key, etc.

[0055] Specifically, after the user selects different mode keys according to needs, different selection instructions will be generated. The control module 1 obtains different selection instructions, determines at least one set of working timings of the current projectile 5 according to different selection instructions, and outputs the working timings to determine the number of stages for which the driving unit 31 is closed. One set of working timings includes multiple pulse signals, each pulse signal is used to control the on / off of one stage of the driving unit 31, and the number of pulse signals in one set of working timings is the same as the number of stages of the driving unit 31. That is to say, after the control module 1 determines the number of stages for which the driving unit 31 is closed, the pulse signals of the corresponding stages include high and low level signals, and the pulse signals of the remaining stages are all low level. And usually, referring to Figure 4 , if the total number of stages of the driving unit 31 is n stages, and when the control module 1 determines that the number of stages for which the driving unit 31 is closed is 3 stages, then the first pulse signal to the third pulse signal in one set of working timings include high and low level signals, and the fourth pulse signal corresponding to the 4th stage driving unit 31 to the nth pulse signal corresponding to the nth stage driving unit 31 only include low level signals, that is, only the first 3 stages of the driving unit 31 are controlled to be closed, and the 4th stage to the nth stage driving unit 31 are not closed. In addition, to ensure that the current projectile 5 is accelerated and fired and accurately reaches the preset firing speed, when setting the pulse signals, usually the time point when the next stage driving unit 31 is closed is before the time point when the previous stage driving unit 31 is disconnected, that is, the rising edge of the pulse signal corresponding to the next stage driving unit 31 is before the falling edge of the pulse signal corresponding to the previous stage driving unit 31.

[0056] Optionally, continuing to refer to Figure 3 and Figure 4 , the mode selection module 6 includes the firing mode 61, the speed gear mode 62, and the system insurance mode 63 of the current projectile 5; the control module 1 is also used to determine a set of working timings and output them according to the speed gear selected by the user when it is determined that the system insurance mode 63 is the on-insurance mode and the firing mode 61 of the current projectile is the single-shot mode; when it is determined that the system insurance mode 63 is the on-insurance mode and the firing mode 61 of the current projectile 5 is the burst mode, determine multiple sets of working timings and output them according to the speed gear selected by the user.

[0057] Among them, the launch mode 61 of the current projectile 5 includes a single-shot mode and a continuous-fire mode. The single-shot mode is that the user quickly leaves after pressing the launch mode button, and the continuous-fire mode is that the user continuously presses the launch mode button until the projectile is launched to a preset number and then leaves. The speed gear mode 62 is the gear corresponding to the preset launch speed finally reached by the current projectile 5. Usually, the speed gear module 62 includes a low speed gear, a medium speed gear, and a high speed gear. Different gears correspond to different preset launch speeds, which can also be understood as the target launch speeds. Different preset launch speeds can be determined according to the different speed gears selected by the user, so that the number of stages of the electromagnetic launch module 3 turned on by the control module 1 is different. The system insurance mode 63 is a protection setting provided to prevent accidental triggering resulting in the launch of the projectile. Usually, the system insurance mode 63 includes an insurance-on mode and an insurance-off mode. When the user does not trigger the system insurance mode 63 button, it is defaulted to the insurance-off mode. At this time, when the user presses the launch button or the launch mode, the current projectile 5 will not be launched either; only when the user turns on the insurance, that is, when in the insurance-on mode, the system will work normally to realize the launch of the current projectile 5.

[0058] Specifically, when the user presses different selection buttons, the control module 1 controls the working timing and outputs according to the different command signals generated when the user presses different buttons. That is to say, when the control module 1 determines that the system insurance mode 63 selected by the user is the insurance-on mode and the launch mode 61 of the current projectile 5 is the single-shot mode, it means that the user's current requirement is a single shot. Then, only a set of working timing can be output to control the launch of the current projectile 5 in the single-shot mode, and the specific form of the pulse signal in a set of working timing is determined according to the speed gear selected by the user and output. Among them, the specific form of the pulse signal is Figure 4 the high and low levels or the low level form shown. When the control module 1 determines that the system insurance mode 63 selected by the user is the insurance-on mode and the launch mode 61 of the current projectile is the continuous-fire mode, it means that the user's current requirement is continuous fire. Then, multiple sets of working timing need to be output so that a set of working timing controls the launch of one current projectile 5, and the specific form of the pulse signal of each set of working timing is determined according to the speed gear selected by the user and output, realizing the interaction between the system and the user, improving the user experience, avoiding accidental triggering, and improving safety.

[0059] In another specific embodiment, optionally, Figure 5 is the structural schematic diagram of the fourth electromagnetic launch system provided by the embodiment of the present invention. Refer to Figures 3 to 5As shown in the figure, the system further includes a display module 7; the display module 7 is electrically connected to the control module 1 and is used to display the speed gear mode 62, the launch mode 61, the system insurance mode 63, and at least one set of working timings, so that the user can intuitively know the launch mode 61, the speed gear mode 62, the system insurance mode 63, and each set of working timings of the current projectile 5, promptly discover abnormal situations, and quickly eliminate the basic abnormal causes when abnormalities occur, thereby improving the launch efficiency and hit rate. Among them, the display method of the display module 7 may include but is not limited to devices such as a display screen, a liquid crystal screen, or a projector that can be used for display, and no limitation is made here. Additionally, when the number of projectiles is multiple, the display module 7 can also display the remaining number of projectiles for the staff to view.

[0060] Optionally, continuing to refer to Figure 5 , the energy storage module 2 includes at least one energy storage capacitor 21, and the energy storage capacitors 21 are connected in parallel with each other.

[0061] Among them, the energy storage capacitor 21 is an electronic component that uses the characteristics of a capacitor to store and release electrical energy. Specifically, when the electrical energy of a single energy storage capacitor 21 can meet the electrical energy required by an electromagnetic coil 32, this embodiment can set the primary energy storage module 2 to include only one energy storage capacitor 21; when the electrical energy of a single energy storage capacitor 21 cannot meet the electrical energy required by an electromagnetic coil 32, this embodiment can set the primary energy storage module 2 to include at least one energy storage capacitor 21, and the energy storage capacitors 21 are connected in parallel with each other to ensure the accelerated launch of the current projectile 5. In this embodiment, the energy storage capacitor 21 may include but is not limited to aluminum electrolytic capacitors.

[0062] Optionally, continuing to refer to Figure 5 As shown in the figure, the system further includes a power supply module 8; the energy storage module 2 further includes a clamping diode 22; the power supply module 8 is electrically connected to each of the parallel energy storage capacitors 21 through the clamping diode 22 and is used to supply power to each energy storage capacitor 21.

[0063] Among them, the power supply module 8 is a power source used to supply power to the energy storage capacitor 21. The clamping diode 22 is an element that uses the one-way conductivity of a diode to limit the potential at a certain point in the circuit. Its function is to fix a certain part of the signal waveform at a selected level without changing the waveform of the signal, ensuring the stability and safety of the circuit.

[0064] Specifically, when supplying power to each energy storage capacitor 21, the power supply module 8 is electrically connected to each of the parallel energy storage capacitors 21 through the clamping diode 22, so that the electrical energy in the power supply module 8 is transmitted to each energy storage capacitor 21 through the clamping diode 22, realizing the power supply to each energy storage capacitor 21. It can be understood that this embodiment is described by taking the energy storage module 2 including multiple parallel energy storage capacitors 21 as an example, and it can also be described by taking one energy storage capacitor 21, and no specific limitation is made.

[0065] Optionally, referring further to Figure 5 , the system further includes an indicator light 9, and the indicator light 9 is connected in series between the power supply module 8 and the clamping diode 22.

[0066] Among them, the indicator light 9 is an electronic component that can be used for lighting. According to requirements, the indicator light 9 can also be replaced with a light-emitting diode for series connection. Specifically, during the normal launch process of the current projectile 5, the driving unit 31 corresponding to the closed stage is in the closed state. At this time, the system works normally and the indicator light 9 is in the lit state. When the driving unit 31 is broken down due to too high voltage or other conditions, at this time the driving unit 31 is in an open circuit, the system works abnormally, and the indicator light 9 goes out. Therefore, the working state of the driving unit 3 can be determined by the lighting or extinguishing of the indicator light 9, discovered and solved in time, the troubleshooting is simplified, the reliability and safety of the system are improved, and the operation and maintenance are facilitated.

[0067] Optionally, referring further to Figure 5 , the system further includes a monitoring module 10 and an alarm module 11; the control module 1 is electrically connected to the monitoring module 10 and the alarm module 11 respectively; the monitoring module 10 is used to monitor the charging and discharging voltages of each level of the energy storage module 2 and the on-off voltage of the driving unit 31; the control module 1 is further used to determine the number of stages for the electromagnetic emission module 3 to be turned on when the charging voltage reaches the preset launch voltage; when the discharging voltage is greater than the preset discharging voltage, or the on-off voltage of the driving unit 31 is greater than the preset on-off voltage, the control module 1 controls the alarm module 11 to give an alarm.

[0068] Among them, the monitoring module 10 is used to monitor the charging voltage and discharging voltage of each level of the energy storage module 2, as well as the on-off voltage of the driving unit 31.

When the control module 1 determines that the discharging voltage is greater than the preset discharging voltage, it indicates that the discharging voltage is too large, which is likely to cause waste and excessive loss; or when it determines that the on-off voltage of the driving unit 31 is greater than the preset on-off voltage, it indicates that the driving unit 31 is open-circuited, and the control module 1 will control the alarm module 11 to give an alarm to prompt the staff to make adjustments or repairs.

[0071] Among them, the switch 311 includes an IGBT high-power switch. The freewheeling diode 312 is connected between two adjacent stages of the energy storage module 2, and is used to send the remaining electric energy after the previous stage energy storage module 2 discharges to push the current projectile 5 to accelerate to the next stage of the energy storage module 2 for storage, so as to be used as the pre-stored voltage for the next stage to accelerate the current projectile 5, realize the accelerated launch of the next stage of the current projectile 5, improve the launch efficiency, and reduce the cost. In addition, the control module 1 controls the drive unit 31 to close, which essentially controls the switch 311 to close, so as to realize the transmission of the electric energy in the energy storage module 2 to the electromagnetic coil 32 through the switch 311, and push the current projectile 5 to accelerate and launch.

[0073] Among them, the electrode control mechanism 12 is a mechanical structure for realizing the loading of the remaining projectiles.

[0075] S110. Determine the number of stages of the electromagnetic launch module to be turned on, so that the turned-on electromagnetic launch module provides power for the current projectile and pushes the current projectile to be launched from the initial launch position on the electromagnetic launch track.

[0076] Specifically, when controlling the launch speed of the current projectile to accurately reach the preset launch speed in the electromagnetic launch track, first determine the number of stages that the electromagnetic launch module needs to be turned on to make the current projectile reach the preset launch speed, and control the corresponding stages of the electromagnetic launch module to be turned on in sequence. At this time, the electrical energy stored in the energy storage module will provide the driving force for the current projectile to accelerate forward through the closed electromagnetic launch module, convert the electrical energy into electromagnetic force, and push the current projectile to be launched from the initial launch position on the electromagnetic launch track under the action of the electromagnetic force. After reaching the preset launch speed, it will exit the electromagnetic launch track at this speed and be launched to the target object to improve the hit rate.

[0077] The technical solution of the embodiment of the present invention determines the number of stages of the electromagnetic launch module to be turned on, so that the turned-on electromagnetic launch module provides power for the current projectile and pushes the current projectile to be launched from the initial launch position on the electromagnetic launch track. Using the above method, the current projectile is launched under the action of electromagnetic force by determining the number of stages of the electromagnetic launch module to be turned on, which improves the concealment while ensuring that the current projectile accurately reaches the preset speed, realizes the precise control of the launch speed, improves the hit rate of the projectile, and reduces the maintenance cost.
