[0002] In the process of using CO2 phase change technology to eject each unit in the phase change ejection box, the existing launch tube phase change ejection device usually adopts manual operation, which is highly random.

[0029] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0030] like Figure 2 As shown, the first embodiment of the present invention proposes an automatic sequential ignition control system for a CO2 phase change ejection device, including a CAN bus 10, a digital input module 20, a controller 30 and a digital output module 40, wherein the digital output module 20 is correspondingly connected to a plurality of phase change ejection units 21, and the controller is electrically connected to the CAN bus 10, the digital input module 20 and the digital output module 40 respectively, and is used to ignite and eject corresponding shells in the plurality of phase change ejection units 21 according to the ignition command sent from the CAN bus 10 or the digital input module 20.

[0031] In the above structure, see Figures 2 to 5In the automatic sequential ignition control system for a CO2 phase-change ejection device provided in this embodiment, a floating unit 22 is provided on the digital output module 20. The controller is electrically connected to the floating unit 22 and is used to unlock the phase-change ejection device, completely lowering the ejection box to the ground and placing it in a free state. The digital output module 20 is provided with a sliding unit 23, which includes an upper sliding unit 231 and a lower sliding unit 232. The controller is electrically connected to the upper sliding unit 231 and the lower sliding unit 232, respectively, to control the ejection box to slide up and down along the sliding frame. The controller 30 is provided with input ports and output ports. The input ports include a CAN bus input port 31 and a digital input port 32. The output ports include a floating unit output port 33, a sliding unit output port 34, and a digital output port 35. In this embodiment, the controller 30 uses the model EPEC3724. The phase change ejection unit 21 includes a left 1 ejection bullet, a left 2 ejection bullet, a left 3 ejection bullet, a left 4 ejection bullet, a left 5 ejection bullet, a right 1 ejection bullet, a right 2 ejection bullet, a right 3 ejection bullet, a right 4 ejection bullet and a right 5 ejection bullet.

[0032] The present invention provides an automatic sequential ignition control method for a CO2 phase change ejection device, which is applied to the automatic sequential ignition control system of the above-mentioned CO2 phase change ejection device. The automatic sequential ignition control method for the CO2 phase change ejection device includes the following steps:

[0033] Step S100: Use two electrical connectors to connect the left ejection box and the right ejection box in the phase change ejection device to multiple phase change ejection units respectively. Each electrical connector controls different ejection tubes on the left ejection box and the right ejection box respectively through multiple pins. The left ejection box is arranged in layers with the left 1 ejection tube, the left 2 ejection tube, the left 3 ejection tube, the left 4 ejection tube and the left 5 ejection tube; the right ejection box is arranged in layers with the right 1 ejection tube, the right 2 ejection tube, the right 3 ejection tube, the right 4 ejection tube and the right 5 ejection tube; the left 3 ejection bullet is centered on the left ejection box, and the right 3 ejection bullet is centered on the right ejection box; each ejection tube is loaded with a corresponding ejection bullet.

[0034] The ejection sequence can be to first eject the projectile in the middle of the left ejection box and the right ejection box, and then choose to eject from both sides.

[0035] The ejection order can also be as follows: left 1 ejection tube -> right 2 ejection tube -> left 2 ejection tube -> right 1 ejection tube -> left 3 ejection tube -> right 3 ejection tube -> left 4 ejection tube -> right 5 ejection tube -> left 5 ejection tube -> right 4 ejection tube.

[0036] Step S200, the controller connects the corresponding digital output signal through logical judgment according to the ignition command sent by the CAN bus or the digital input module, and controls the left 1 ejection bullet, the left 2 ejection bullet, the left 3 ejection bullet, the left 4 ejection bullet, the left 5 ejection bullet, the right 1 ejection bullet, the right 2 ejection bullet, the right 3 ejection bullet, the right 4 ejection bullet and the right 5 ejection bullet to ignite and eject according to the preset ejection order.

[0037] Furthermore, the automatic sequential ignition control method of the CO2 phase change ejection device provided in this embodiment further includes, before step S200:

[0038] Step S200A: When the phase-change ejection device is ready to be in place, the sliding unit is controlled to telescope the sliding cylinder installed on the ejection bracket, and the left ejection box and the right ejection box are moved downward together with the sliding frame. When close to the ground, the floating valve connected to the floating unit is energized to connect the rod chamber and the rodless chamber, thereby unlocking the phase-change ejection device and completely lowering the ejection box to the ground, causing the ejection box to be in a free state.

[0039] like Figures 2 to 5 As shown, the automatic sequential ignition control system and method of the CO2 phase change ejection device provided in this embodiment has the following working principles:

[0040] The CO2 phase change ejection device is a device that ejects the projectile by generating high pressure during the process of converting solid CO2 into gaseous CO2. The CO2 phase change ejection device mainly includes a right ejection box 100, a left ejection box 200, an ejection bracket 300 and an ignition control system 400. The structure of the CO2 phase change ejection device is as follows: Figure 3 shown.

[0041] The left and right ejection boxes are exactly the same and can be loaded with 5 ejection tubes or other different numbers of ejection tubes. If it is placed on the left side of the ejection bracket 300, it is defined as the left ejection box 200, and if it is placed on the right side of the ejection bracket 300, it is defined as the right ejection box 100. Each ejection box contains 5 ejection tubes, namely, the left ejection tube 1, the left ejection tube 2, the left ejection tube 3, the left ejection tube 4, the left ejection tube 5, the right ejection tube 1, the right ejection tube 2, the right ejection tube 3, the right ejection tube 4 and the right ejection tube 5. Figure 3 The left ejection box and the right ejection box are connected to different input ports of the ignition control system controller through two electrical connectors to realize automatic identification of the left ejection box and the right ejection box. Different pins are defined on each electrical connector to control the five different ejection tubes on the ejection box. The schematic diagram of the ignition control system is shown in the figure. Figure 2 shown.

[0042] The ignition control system receives the ignition command through the CAN bus or digital input signal (DI), and connects the corresponding digital output DO signal through logical judgment to ignite and eject the corresponding bullets among the left 1 to left 5 bullets and the right 1 to right 5 bullets.

[0043] The ejection order is as follows: left 1 ejection tube -> right 2 ejection tube -> left 2 ejection tube -> right 1 ejection tube -> left 3 ejection tube -> right 3 ejection tube -> left 4 ejection tube -> right 5 ejection tube -> left 5 ejection tube -> right 4 ejection tube. The automatic ejection order is as follows: Figure 4 shown.

[0044] If all the projectiles in the ejection tube have been ejected, the projectile icon and ejection sequence arrow on the screen will turn gray. If the projectile is in the ejection waiting state, the projectile icon will be green and the ejection sequence arrow will be purple. The number of ejections can be set according to the specified number. After confirming the number of ejections, press the ejection start button. The ignition control system will eject the three projectiles in the left ejection tube 2, the right ejection tube 1, and the left ejection tube 3 in a specific time sequence. Once the ejection is completed, the corresponding projectile icon and ejection sequence arrow will turn gray.

[0045] This ejection method offers two advantages over traditional random launch: First, the ejection starts from the upper layer of the left and right ejection boxes, then the middle layer, and finally the lower layer. This lowers the center of gravity of the ejection box on the ejection bracket, preventing the vibration generated during continuous launch from affecting the launch accuracy of subsequent projectiles. Second, the CO2 phase change ejection device uses ground-supported ejection, and the huge thrust generated during the ejection process is reacted to the ground through the bottom of the phase change unit.

[0046] When the ejection device is ready to be in place, the sliding oil cylinder installed on the ejection bracket 300 is extended and retracted to move the left ejection box and the right ejection box downward together with the sliding frame. When close to the ground, the floating valve is energized to connect the rod chamber and the rodless chamber. This unlocks the ejection device and completely lowers the ejection box to the ground. The ejection box is in a free state, which can eliminate the influence of the upward impact generated during the launch on the sliding oil cylinder; the bottom end of the phase change unit 500 contacts the ground to realize the ground support of the ejection box. The support state of the ejection device is as follows: Figure 5 shown.

[0047] In order to adapt to the ejection requirements of medium-hard ground, the projectiles in the middle of the left and right ejection boxes are ejected first, and then ejected from both sides. This can solve the problem of ground deformation caused by random ejection during the ejection process, which causes the landing area to be squeezed towards the middle into a bulge, affecting the accuracy of subsequent ejections.

[0048] The automatic sequential ignition control system and method for the CO2 phase change ejection device provided in this embodiment, compared with the prior art, uses a CAN bus, a digital input module, a controller, and a digital output module, wherein the digital output module is correspondingly connected to multiple phase change ejection units, and the controller is electrically connected to the CAN bus, the digital input module, and the digital output module, respectively, for igniting and ejecting corresponding shells in the multiple phase change ejection units according to the ignition commands sent from the CAN bus or the digital input module. The automatic sequential ignition control system and method for the CO2 phase change ejection device provided in this embodiment improves the accuracy of projectile ejection through automatic ejection; improves the visualization of projectile ejection, and can timely understand the status of each projectile; automatically controls the ejection in sequence, reduces system disturbances, and improves the stability and accuracy during the continuous ejection process; and automatically controls the ejection in sequence, which can adapt to the ejection requirements of complex ground and improve the accuracy of ejection.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the invention.
