Detailed Implementation
[0016] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
[0017] like Figure 1 As shown, an embodiment of the present invention proposes a method for determining the layout location of a media device on a launch vehicle, comprising the following steps: Step 101: Obtain observation event data from the launch vehicle; Step 102: Determine the observation requirement data based on the observed event data; Step 103: Obtain the installation location data of the media device based on the preset rocket structure layout data; Step 104: Map the observed event data and the media device installation location data to obtain mapped data; Step 105: Obtain the initial media device layout location based on the mapping data, the observation event data, and the observation requirement data; Step 106: Based on the verification results of the initial media device layout position, adjust the initial media device layout position to obtain the media device layout position on the target arrow.
[0018] The method for determining the layout location of onboard media devices in a launch vehicle according to embodiments of the present invention acquires observation event data on the launch vehicle, determines observation requirement data based on the observation event data, determines media device installation location data based on preset rocket structure layout data, maps the observation event data and media device installation location data to obtain mapped data, obtains the initial media device layout location based on the mapped data and observation requirement data, and finally adjusts the initial media device layout location based on the verification results to obtain the target onboard media device layout location. This method can improve the accuracy of onboard media device layout, reduce the number of unnecessary devices to control costs, weight and power consumption, and achieve the best balance between observation efficiency and economy.
[0019] In this embodiment, a camera is used as an example of a media device for explanation.
[0020] In an optional embodiment of the present invention, step 101 includes: Step 1011: Obtain the flight sequence and mission objectives of the launch vehicle; Specifically, the flight sequence of a launch vehicle generally includes stages such as pre-launch preparation, ascent phase, interstage separation, fairing separation, satellite-rocket separation, final stage shutdown, and on-orbit mission. Mission objectives can include monitoring targets, such as verifying the start / shutdown sequence, synchronization, and operating status of multiple engines (e.g., plume stability, plume symmetry); confirming the integrity of interstage separation actions (e.g., unlocking, separation, and remote safety); verifying the fairing separation sequence, symmetry, and protection effect on the payload; confirming the safe separation of the satellite from the final stage and initial attitude stability; and evaluating the impact of liquid surface sloshing on the rocket's attitude control (e.g., longitudinal coupling vibration suppression), etc.
[0021] Step 1012: Determine the observation event data on the launch vehicle based on the flight sequence and mission objectives.
[0022] Specifically, historical flight sequences and mission objectives of launch vehicles can be stored in relation to observed events to create a pre-defined observation event database. Then, based on the acquired flight sequences and mission objectives, the corresponding observation events are retrieved from this database and used as the observation event data for the launch vehicle, thus improving processing efficiency. This observation event data for the launch vehicle includes, but is not limited to: time-sharing start-up, shutdown, and operational status of the first-stage multi-engine parallel system; interstage separation processes (which may include primary and secondary separation depending on the separation method); fairing separation processes (including transverse and longitudinal separation); satellite-launch separation processes; propellant tank surface sloshing; and other events of special interest (such as booster separation and special mechanism actions). The corresponding observation event data is determined based on the actual situation and the launch vehicle's flight sequence and mission objectives.
[0023] In an optional embodiment of the present invention, step 102 includes: Step 1021: Determine the observation target, observation angle, and observation parameters based on the observed event data; Specifically, the observation target is extracted directly from the observation event data. From the perspectives of mechanical principles, motion trajectory and optical imaging, the best viewing angle (such as frontal view, side view, top view, and bottom view) is analyzed. Based on the size, distance and expected displacement range of the observation target, the required field of view range parameters and depth parameters of the media device are determined to ensure that the entire process of the target event can be clearly captured.
[0024] Here, some of the observed event data and the observed targets extracted from them can be shown in Table 1: Table 1. Observational event data and the observation targets extracted from them.
[0025] In one specific embodiment, the observation target is the separation surface (axial direction), whose motion characteristic is mainly axial relative displacement. It is necessary to directly observe the change in the separation gap (such as the distance from 0 to complete separation) to reflect the separation progress. Therefore, the corresponding observation perspective is frontal (along the longitudinal axis). The observation target is the separation surface (radial offset), whose motion characteristic is radial slight oscillation. It is necessary to clearly capture the lateral offset of the separation surface to determine whether the separation is symmetrical. Therefore, the corresponding observation perspective is side-view (perpendicular to the longitudinal axis). The observation target is the engine nozzle, whose motion characteristic is axial injection plus vector oscillation. It is necessary to observe the vector oscillation angle from the side and observe the nozzle expansion / contraction state from the front. Therefore, the corresponding observation perspective is side-view plus frontal view. The observation target is the fairing half, whose motion characteristic is radial expansion (longitudinal split). It is necessary to avoid the rocket body obstructing the observation of the half's expansion angle and separation trajectory. Therefore, the corresponding observation perspective is side-view. The observation target is the tank liquid surface, whose motion characteristic is swaying in the vertical acceleration direction. It is necessary to maximize the capture of the undulation amplitude of the liquid surface and avoid "visual compression" caused by the perspective being parallel to the swaying direction. Therefore, the corresponding observation perspective is perpendicular to the swaying direction.
[0026] In practice, historical observation events and their corresponding historical observation targets and perspectives can be stored in an event and target database. The corresponding observation targets and perspectives can be directly extracted from the database through the observation events in the observation event data to improve work efficiency.
[0027] The observation parameters include the field of view angle parameter and the depth of field parameter.
[0028] pass The field of view parameters are calculated; where F is the field of view parameter. The total coverage width required for the observed target, , To observe the maximum width of the target itself, Let D be the maximum horizontal displacement range during the observation event, and D be the distance between the media device and the observation target.
[0029] pass The depth-of-field parameters are calculated; among them, For depth of field parameters, For the long-term parameters, D is the distance between the media device and the observed target, f is the lens focal length, and N is the aperture coefficient (f / value). Among them, the depth-of-field parameter must meet the following requirements: ,in, This refers to the range of object distances for observing the motion of the target.
[0030] Step 1022: Determine the observation requirement data based on the observation target, the observation angle, and the observation parameters.
[0031] Specifically, the observation requirements data include the observation target, observation perspective, and observation parameters.
[0032] In an optional embodiment of the present invention, step 103 includes: Step 1031: Determine candidate installation locations based on preset rocket structure layout data; Specifically, based on the structural diagrams, functions, and locations of each structure in the pre-set rocket structural layout data, all locations that meet the conditions for installing media devices can be preliminarily determined as candidate installation locations, such as the engine compartment, inter-compartment section, carbon dioxide rear bottom, short shell, satellite support, etc.
[0033] Step 1032: Filter the candidate installation locations according to preset filtering conditions to obtain media device installation location data.
[0034] Specifically, preset screening criteria may include: the structural strength of the installation location must be able to withstand the weight of the media device and fixing equipment, vibrations during flight, and must not penetrate load-bearing structures; it must withstand extreme environments, avoid direct exposure to rocket jets, separation debris, and propellant leakage areas, must not obstruct the operation of critical equipment, and must meet installation space requirements. All candidate installation locations are screened using these preset screening criteria, and those meeting the criteria are included in the media device installation location data. In practice, analysis can be conducted to determine if the candidate installation location's line of sight is obstructed by other components (such as conduits, cables, and structural parts), and to assess the vibrations, impacts, temperatures, and electromagnetic environments it will experience during flight. This helps determine if the environmental requirements for media device operation are met. The ease of implementation, including installation space, wiring, power supply, and thermal control, can also be assessed to ensure compliance with the preset screening criteria. Further, specific range values can be set for each condition in the preset screening criteria to determine if a candidate installation location falls within these ranges; if so, it can be included in the media device installation location data.
[0035] In an optional embodiment of the present invention, step 104 includes: Step 1041: Determine the mapping matrix based on the observed event data and the media device installation location data; Specifically, the observed event data is used as row data and the media device installation location data is used as column data to form a mapping matrix, which serves as the basis for subsequent analysis of the observation effectiveness of each media device installation location for each observed event.
[0036] Step 1042: Verify the observation validity of the mapping matrix according to the preset verification conditions to obtain the mapping data.
[0037] Specifically, the preset verification conditions include: designating the media device installation location that provides the most direct and complete view of the observed event as the primary observation location; designating the media device installation location that provides a side view, supplementary view, or backup view of the observed event as an auxiliary / verification observation location; and designating the media device installation location that cannot be effectively observed due to obstruction or poor viewing angle as an unobservable location. Based on these preset verification conditions, the validity of each media device installation location data in the mapping matrix is verified, and each location is marked as at least one of the following: primary observation location, auxiliary / verification observation location, or unobservable location. The marked mapping matrix is the mapping data.
[0038] In an optional embodiment of the present invention, step 105 includes: Step 1051: Determine the location of the media device based on the mapping data, the observation event data, and the observation demand data; Specifically, the set of observed events is ,in, For the i-th observed event (such as interstage separation, engine start-up, etc.), the set of media device installation locations is: in, For the installation location of the j-th media device (e.g., inter-cabinet section, short shell, etc.), the mapping data is: ,in, Weights are assigned to the observed events in the mapped data, with observed events having a weight of 1 considered as general events and observed events having a weight greater than 1 considered as important events. The location of the media device is determined through the following steps: Initialize the overridden event set Select location set Each time, select the position from the remaining positions that covers the most uncovered events. ,join in The events covered by this event are added to S until S = E, where E is the set of all observed events in the mapped data. The above steps ensure that each observed event has at least one observation location.
[0039] For important observation events (its weight) ),pass Ensure important observation events At least This method utilizes multiple locations for coverage, enabling multi-view coverage of important observation events, where n represents the number of observation locations in the mapped data. For each element in the mapping data, the element represents whether the installation location of the j-th media device can effectively observe the i-th observation event. For decision variables, the value can be 0 or 1. Then choose the location Install media devices, if Then do not select the position Install media devices.
[0040] pass Calculated position The coverage efficiency, according to Sort the data in descending order, and select the top h positions (where h is an integer greater than 1) as the media device positions. For position The coverage efficiency, where m is the number of observed events. For each element in the mapping data, it represents whether the installation location of the j-th media device can effectively observe the i-th observation event.
[0041] The initial set of media device locations is determined through the above steps. .
[0042] In addition, it is possible to predict potential events. and the corresponding mapping matrix ,verify If not satisfied, supplement the coverage. The minimum number of positions required to obtain the final set of positions. ,in, For the initial set of media device locations, For the set of locations of the target media devices, .
[0043] Step 1052: Determine the number of media devices based on their locations; Specifically, through The number of media devices, k, is calculated.
[0044] Step 1053: Obtain the initial media device layout position based on the number of media devices and the position of the media devices.
[0045] Specifically, the initial media device layout includes the number of media devices and their locations.
[0046] In an optional embodiment of the present invention, step 106 includes: Step 1061: Perform a simulation test based on the initial media device layout position to obtain the simulation test results; Specifically, the 3D model of the launch vehicle can be imported into the simulation testing software. The 3D model models the media devices and mounting brackets according to actual scale (simplifying the model while retaining key parameters such as lens optical axis direction and field of view). The flight sequence of the launch vehicle, the observation target, the observation angle, and the observation parameters are used as input parameters to the simulation testing software for simulation testing. The spatial region where the event occurs (e.g., the interstage separation surface is located between the top of the first stage and the bottom of the second stage) is located, and the positions of candidate media devices associated with the event are activated (based on the mapping matrix). The model generates a "field cone" (a three-dimensional cone with the lens as the vertex and the field angle parameter as the angle, representing the observable range) for the media device. The event process (such as the dynamic process of the separation surface from closing to completely separating) is simulated frame by frame to obtain the simulation test results. Here, the simulation test results include the observation results of each media device (such as the observed target area).
[0047] Step 1062: Visually verify the layout position of the initial media device based on the simulation test results to obtain the verification results; Specifically, the occlusion rate is calculated as the area of the occluded target divided by the total area of the target. If the occlusion rate is 0 or less than the preset value, the verification result is considered good; if the occlusion rate is greater than or equal to the preset value, the verification result is considered poor.
[0048] Step 1063: Adjust the initial media device layout position according to the verification result to obtain the media device layout position on the target arrow.
[0049] Specifically, if the verification result indicates poor observation results, adjustments need to be made to the initial media device layout, including the position and quantity of the media devices, to ensure unobstructed observation of the target and achieve the desired effect. These adjustments can be made in at least one of the following ways: adjusting the media device position (e.g., moving it from the outside to the inside of the tank section to avoid obstruction by the support), adjusting the media device angle (e.g., increasing the pitch angle by 10° to avoid obstruction by the tank head), increasing the media device's field of view (e.g., from 30° to 45°), moving the installation position to a more distant location (increasing the observation distance to expand the coverage area), replacing the lens with a large depth-of-field lens, adding a media device image stabilization bracket, or adding a new installation position with a different angle (e.g., supplementing the original frontal view with a side view), etc.
[0050] A specific embodiment of the method for determining the layout position of the onboard media device of a launch vehicle according to an embodiment of the present invention includes: Step 111: Obtain observation event data from the launch vehicle; The system acquires the launch vehicle's flight sequence and mission objectives, and retrieves onboard observation event data from a pre-defined observation event database. These observation events include, for example, first-stage engine operation, interstage separation, second-stage engine operation, fairing separation, and satellite-launch separation.
[0051] Step 112: Determine the observation requirement data based on the observed event data; The observation target is extracted directly from the observed event data, and then the observation angle and parameters for observing the target are determined. This serves as the observation requirement data, providing a basis for subsequently determining the installation location and quantity of media devices. For example, interstage separation requires observation of the unlocking of the separation surface and the separation process of the two bodies from the front or side.
[0052] Step 113: Obtain the installation location data of the media device based on the preset rocket structure layout data; Based on the preset rocket structure layout data, all possible locations for installing media devices are listed, and then filtered according to preset filtering conditions to obtain the media device installation location data.
[0053] Step 114: Map the observed event data and the media device installation location data to obtain mapped data; The observed event data is used as row data and the media device installation location data is used as column data to form a mapping matrix. Then, the validity of the matrix is verified according to preset verification conditions to obtain the mapping data.
[0054] Step 115: Obtain the initial media device layout location based on the mapping data, the observation event data, and the observation requirement data; Based on the observation targets, viewing angles, and parameters in the observation requirements data, as well as preset standards, such as ensuring that each key observation event on the list has at least one main observation location where media devices can clearly and reliably cover it; for particularly important events (such as interstage separation and satellite-launch separation), consider deploying media devices from different angles to provide multi-dimensional image data for comprehensive analysis and to form a certain degree of redundancy, improving the reliability of data acquisition; prioritize installation locations where a single media device can clearly observe multiple key events simultaneously, optimizing the viewing angle and field of view to cover the most events with the fewest media devices, thereby reducing the total number; while meeting the requirements of the current model, consider the possible evolution of subsequent models (such as the addition of booster separation events after changing to a universal core stage bundled configuration, changes in fairing separation observation locations, etc.), and appropriately reserve interfaces and fields of view for compatibility or easy expansion when selecting installation locations. First, assign weights to the observation events in the mapping data, then determine the media device locations based on the mapping data, observation event data, etc., and then obtain the number of media devices. The media device locations and the number of media devices together constitute the initial media device layout.
[0055] The initial media device layout is as follows: one media device is installed in the short shell behind the second-stage oxygen tank, which can be used to observe the interstage separation process forward and the second-stage engine operation status backward (one device for multiple purposes, covering two events); two media devices are installed on the satellite support, which can be aligned with the fairing and satellite interface respectively, for optimal observation of fairing separation and satellite-rocket separation (multi-angle coverage of important events); one media device is installed in the first-stage engine nacelle for observing the first-stage engine operation status (dedicated); two media devices are installed in the inter-tank section, whose viewpoints can cover interstage separation (as an auxiliary viewpoint) and the overall status of the rocket body, and reserve the field of view for future observation of the separation of the universal core stage bundled configuration fairing (compatibility design).
[0056] Step 116: Based on the verification results of the initial media device layout position, adjust the initial media device layout position to obtain the media device layout position on the target arrow.
[0057] A 3D model of the launch vehicle equipped with media devices arranged according to the initial media device layout was imported into simulation testing software for simulation testing. The perspectives at various stages of flight were simulated to check for obstructions and sufficiency of the field of view. Based on the verification results, the installation position, angle, or number of devices was adjusted until all observation requirements were fully met. Table 2 shows the final determined layout of the target rocket's onboard media devices. Table 2 Layout and location of the target rocket's onboard media device
[0058] The method for determining the layout and location of onboard media devices in a launch vehicle, as described in this invention, establishes a scientific and systematic analysis and decision-making process. It comprehensively considers the key action sequences, structural layout constraints, and optical observation requirements during the flight mission, thereby accurately determining the placement and quantity of media devices. This method not only ensures reliable observation of critical events such as engine operation, stage separation, fairing jettisoning, and satellite-launch separation, effectively supporting fault diagnosis and flight verification, but also focuses on optimizing resource allocation, reducing unnecessary equipment to control cost, weight, and power consumption, achieving the best balance between observation efficiency and economy. It can be widely applied to the design of various launch vehicles, especially suitable for the development of new models and the optimization of electrical systems in improved models.
