Description

Technical Field

[0001] The invention relates to the technical field of spacecraft assembly, and in particular to a method for decoupling satellite north and south cabin cable networks. Background Art

[0002] The satellite low-frequency cable network is the hub of the low-frequency power and signal connection of the entire satellite, and is a key equipment for the satellite power supply and distribution subsystem. At present, the design and production of the cable network includes two parts: one is to design the satellite low-frequency cable network contact table according to the distribution relationship of the power distribution resources, pyrotechnic resources, telemetry resources, remote control resources, heaters and other resources of each subsystem; the other is to complete the cable direction design and branch design according to the "single machine-electrical connector-contact" connection relationship represented by the satellite unit position layout diagram and the satellite low-frequency cable network contact table. Taking the current communication satellite as an example, the satellite units are mainly distributed on the north and south instrument cabin boards. With the substantial increase in satellite power demand, the number of satellite units has gradually increased. The demand and allocation of various resources have become more complicated, resulting in more complex cable network connection relationships and a huge number of branches. During the design process, it is easy for the cables of the north and south instrument cabins to be coupled into a large bundle or several large bundles. This situation makes the cable network direction design more difficult. The physical cable products cannot be assembled during the installation of the entire satellite, or there is interference with the satellite's intermediate bearing cylinder. Therefore, designers need to decouple the coupling cables of the north and south instrument cabin boards.

[0003] Traditional decoupling design requires designers to manually count and locate coupling points. However, with the complexity of cable branching relationships, the coupling points of the north-south instrument panel coupling cables may contain multiple or even dozens of coupling points. Manually locating all coupling points in hundreds of electrical connectors of dozens of single machines and selecting appropriate transition solutions for decoupling is a huge process with a huge workload and is prone to problems such as connection relationship drawing errors and single-machine equipment missing statistics, making the cable network decoupling design time-consuming, error-prone, and inefficient. Summary of the invention

[0004] The purpose of the present invention is to provide a satellite north and south cabin cable network decoupling method to solve the problems of traditional cable network decoupling design methods being time-consuming, error-prone and inefficient, and to meet the increasing model mission requirements.

[0005] In order to achieve the above object, the present invention provides a method for decoupling a satellite north and south cabin cable network, comprising the steps of:

[0008] According to the stand-alone electrical connector position information corresponding to each of the stand-alone electrical connectors in the stand-alone position layout auxiliary table, a cable contact point expected connection relationship matrix is ​​generated to avoid different cabin board connection coupling rules; wherein the elements in the cable contact point expected connection relationship matrix are used to characterize whether the connection relationship between each of the stand-alone electrical connectors belongs to the expected state;

[0013] If the cables do not have a coupling connection relationship or have been decoupled from different cabin cables by the transition electrical connector, it is determined whether there is a cable to be parsed with the next sequence cable number;

[0014] If there are cables to be parsed with the next sequence cable number, the coupling connection relationship analysis and processing are performed on the cables to be parsed in sequence until the parsing processing of all cables in the cable network contact table is completed.

[0015] Optionally, the elements in the cable contact connection relationship matrix are 0 and 1, and the element 1 in the cable contact connection relationship matrix represents that there is a contact connection relationship between the corresponding two stand-alone electrical connectors, and the element 0 in the cable contact connection relationship matrix represents that there is no contact connection relationship between the corresponding two stand-alone electrical connectors.

[0017] Optionally, solving the coupling matrix of the cable corresponding to the cable number according to the cable connection relationship matrix and the cable connection expected connection relationship matrix includes:

[0018] The coupling matrix of the cable corresponding to the cable number is obtained by subtracting the Hadamard product of the cable connection relationship matrix and the cable connection expected relationship matrix from the cable connection relationship matrix.

[0019] Optionally, judging whether the cables have a coupling connection relationship according to the coupling matrix includes:

[0020] It is determined whether the coupling matrix is ​​an all-zero matrix. If it is not an all-zero matrix, it is determined that the corresponding cables have a coupling connection relationship.

At the same time, it greatly reduces the complexity of the relationship between cable branches, reduces the difficulty of the route and laying of the cable network during the satellite assembly process, and effectively improves the efficiency and accuracy of the digital design of the cable network.

In addition, the word "connected" here includes any direct and indirect electrical connection means. Indirect electrical connection means include connection through other devices.

[0033] As the number of satellites and functional requirements increase, the cable network connection relationship becomes more complicated. In order to achieve the purpose of reducing the complexity of the relationship between cable branches, alleviate the difficulty of the cable network's direction and laying during the satellite assembly process, effectively solve the problem of the traditional cable network decoupling design method being time-consuming, error-prone, and inefficient, and meet the increasing model mission requirements; the present invention provides a satellite north and south cabin cable network decoupling method, by quickly parsing the satellite low-frequency cable network contact table, analyzing the existence of cross-cabin coupled cables on the north and south cabins, solving the problem of cable coupling between north and south cabins in the traditional cable network design process. The present invention has significant advantages in the decoupling of large multi-branch complex cross-cabin coupled cables.

[0034] Figure 1 The satellite north and south cabin cable network decoupling method provided by the first embodiment of the present invention includes the following steps:

[0035] S101: Get an input file, which includes a cable network contact table and a stand-alone position layout auxiliary table; the cable network contact table of this embodiment is a table used to record the relevant information of each contact in the satellite low-frequency cable network, and each cable has a one-to-one corresponding cable number in the cable network contact table, that is, the cable number is used as the corresponding identification of each cable; and each cable includes a starting end and at least one branch for connecting to the corresponding stand-alone electrical connector; the stand-alone position layout auxiliary table is a table used to record the position information of each stand-alone electrical connector. The input file of this embodiment can be a package file of the cable network contact table and the stand-alone position layout auxiliary table, so after obtaining the input file, it is necessary to extract the cable network contact table and the stand-alone position layout auxiliary table through parsing; then enter step S102.

[0036] Optionally, a cable network point table template such as Figure 3 As shown, based on the keyword "cable number" in the table, the number of cables in the contact table can be parsed, wherein a cable with a certain cable number has a corresponding starting end, branch 1, branch 2, and branch 3; the starting end in the table is specifically single machine 1-electrical connector 1, branch 1 is single machine 2-electrical connector 1, branch 2 is single machine 2-electrical connector 2, and branch 3 is single machine 3-electrical connector 1, and the contact numbers in the table correspond one-to-one to the contacts on the single machine-electrical connector.

[0037] S102: Sequentially extract the stand-alone electrical connector information corresponding to the cable number from the cable network contact table, and parse the cable contact connection relationship in the stand-alone electrical connector information to generate a cable contact connection relationship matrix between each stand-alone electrical connector; wherein the elements in the cable contact relationship matrix are used to characterize whether each of the stand-alone electrical connectors has a contact connection relationship. Specifically, according to the order of the cable numbers, the stand-alone electrical connector information corresponding to the current cable number can be extracted in sequence, and the stand-alone electrical connector information includes information such as the stand-alone electrical connector mark and the contact number of the stand-alone electrical connector, such as Figure 3 As shown; after extracting the information of N stand-alone electrical connectors of the current cable to be analyzed, the contact connection relationship between each other is determined according to the contact number between each stand-alone electrical connector, thereby forming an N×N cable contact connection relationship matrix H, in which different elements are used to represent whether each stand-alone electrical connector has a contact connection relationship between each other; for example, the elements in the cable contact connection relationship matrix are 0 and 1, and the element 1 in the cable contact connection relationship matrix represents that the corresponding two stand-alone electrical connectors have a contact connection relationship, and the element 0 in the cable contact connection relationship matrix represents that the corresponding two stand-alone electrical connectors do not have a contact connection relationship. Combined with Figure 3 The cable contact connection relationship H that can be constructed by the single-machine electrical connector information corresponding to the cable number shown is:

[0038]

[0039] The elements in the matrix H are defined as follows: if there is a contact connection relationship between the single-machine electrical connectors, it is recorded as "1", and if there is no contact connection relationship between the single-machine electrical connectors, it is recorded as "0".

[0040] S103: Generate a cable contact point expected connection relationship matrix based on the single-machine electrical connector position information corresponding to each single-machine electrical connector in the single-machine position layout auxiliary table to avoid different cabin board connection coupling rules; wherein the elements in the cable contact point expected connection relationship matrix are used to characterize whether the connection relationship between each single-machine electrical connector belongs to the expected state.

[0041] Optionally, a single machine location layout auxiliary table template such as Figure 4 As shown, the single-machine position information here includes "South cabin board" / "North cabin board", and each single-machine electrical connector is distributed on the "South cabin board" or "North cabin board"; the rule for avoiding connection coupling between different cabin boards means that if there is a connection relationship between the single-machine electrical connectors on the north and south cabin boards, the cable network will form a connection coupling between the north and south cabin boards, so it is not desired that the single-machine electrical connectors between the north and south cabin boards have a connection relationship; on the contrary, it is a desired state if there is a connection relationship between the single-machine electrical connectors on the same cabin board; therefore, based on the actual record of each single-machine electrical connector in the single-machine position layout auxiliary table and its contact information, the "rule for avoiding connection coupling between different cabin boards" can be used to avoid the connection coupling between the single-machine electrical connectors on the south and north cabin boards. "Generate a cable contact point expected connection relationship matrix, for example, based on the extracted N stand-alone electrical connector position information, generate an N×N cable contact point expected connection relationship matrix Q, in which different elements are used to represent whether the interface connection state between each stand-alone electrical connector is in the expected state; for example, the elements of the cable contact point expected connection relationship matrix are 0 and 1, and the element 1 in the cable contact point expected connection relationship matrix represents that the corresponding two stand-alone electrical connectors are expected to have a connection relationship, and the element 0 in the cable contact point expected connection relationship matrix represents that the corresponding two stand-alone electrical connectors are not expected to have a connection relationship. Combined Figure 3 The cable contact expected connection relationship matrix Q that can be constructed from the single-machine electrical connector information corresponding to the cable number shown is:

[0042]

[0043] Among them, the elements in the matrix Q are defined as follows: with the position of the south deck as the reference position, there can be a connection relationship between the single-machine electrical connectors on the south deck, and the corresponding elements in the cable contact expected connection relationship matrix Q are recorded as "1"; there can be a connection relationship between the single-machine electrical connectors on the north deck, and the corresponding elements in the cable contact expected connection relationship matrix Q are recorded as "1"; if there is a connection relationship between the single-machine electrical connector on the south deck and the single-machine electrical connector on the north deck, the cable network will form a connection coupling between the north and south decks, so the single-machine electrical connectors between the north and south decks do not want to have a connection relationship, so the corresponding elements in the cable contact expected connection relationship matrix Q are recorded as "0".

[0044] S104: Solve the coupling matrix of the cable corresponding to the cable number according to the cable connection relationship matrix and the cable connection expected connection relationship matrix. Specifically, step S104 includes: subtracting the Hadamard product of the cable connection relationship matrix and the cable connection expected connection relationship matrix from the cable connection relationship matrix to obtain the coupling matrix of the cable corresponding to the cable number. Assume that the coupling matrix of the cable is W, then the coupling matrix W is obtained by subtracting the Hadamard product of the cable connection relationship matrix H and the cable connection expected connection relationship matrix Q from the cable connection relationship matrix H: W = HH⊙Q.

[0045] S105: Determine whether the cable has a coupling connection relationship according to the coupling matrix. Specifically, step S105 includes: determining whether the coupling matrix is ​​an all-zero matrix. If it is not an all-zero matrix, determining that the corresponding cable has a coupling connection relationship. If the coupling matrix W obtained by solution is an N×N all-zero matrix, it means that the cable does not have north-south cross-cabin coupling; conversely, if the coupling matrix W is not an all-zero matrix, it means that the cable has north-south cross-cabin coupling. Specifically, the coupling connection relationship of the matrix W is parsed. If the element in the matrix W is "1", it means that there is a coupling connection relationship between the two stand-alone electrical connectors corresponding to the element, and it is necessary to interrupt it by setting a transition in the subsequent steps; if the element in the matrix W is "0", it means that there is no coupling connection relationship between the two stand-alone electrical connectors corresponding to the element. In combination with the above optional examples, the cable coupling matrix W obtained by solution is:

[0046]

[0047] From the coupling matrix W of the cable, it can be determined that there is a north-south panel coupling connection relationship at the contact points between "stand-alone 1-electrical connector 1" and "stand-alone 2-electrical connector 2"; there is a north-south panel coupling connection relationship at the contact points between "stand-alone 2-electrical connector 1" and "stand-alone 3-electrical connector 1"; at this time, it is necessary to decouple the coupling connection relationships between these different panels.

[0048] S106: If the cables are coupled to each other, decoupling of cables from different cabins is performed by setting at least one transition electrical connector according to a preset decoupling transition rule.

[0049] In specific implementation, step S106 includes: if it is determined that there is a coupling connection relationship between the cables, then based on the analysis result of the coupling connection relationship of the cables, a target transition rule is selected from the preset decoupling transition rules; based on the setting number of transition electrical connectors determined by the target transition rule, the transition decoupling of cables of different cabins is performed by setting the transition electrical connectors. That is, this embodiment generates a corresponding transition scheme according to the coupling connection relationship between the north and south cabins, and the generation of the transition scheme follows different transition setting principles; the transition electrical connector of this embodiment preferably adopts the J36A series electrical connector, and the number of cores of the electrical connector includes 9 cores, 17 cores, 26 cores, 38 cores, 52 cores, 62 cores, and 74 cores.

[0050] Optionally, the decoupling transition rule includes a single coupling bundle single transition rule, a rule for minimizing the number of transition electrical connectors, and a rule for bundling cables of the same signal type. That is, this embodiment can use three transition schemes to perform transition decoupling on the coupling connection relationship in the cable; the specific transition schemes are as follows:

[0051] Transition plan 1: Following the single coupling bundle single transition rule, all coupling connections between two stand-alone electrical connectors are defined as a coupling bundle, that is, a transition electrical connector is set through a coupling bundle to interrupt it, so as to achieve the purpose of decoupling the north and south cabin cable networks.

[0052] Transition plan two: follow the rule of minimizing the number of transition electrical connectors, that is, according to the number of coupling contacts of the north and south cabin cable networks, uniformly set one or several transition electrical connectors (the number of electrical connector cores matches the number of coupling contacts), that is, maximize the merging of coupling bundles for transition settings, reduce the number of transition electrical connectors, and achieve the purpose of decoupling the north and south cabin cable networks.

[0053] Transition plan three: follow the same signal type cable bundling rules, according to the actual use requirements, the same signal type cables are combined for transition settings, each signal type is uniformly set with one or several transition electrical connectors (the number of electrical connector cores matches the number of coupling contacts) to achieve the purpose of decoupling the north and south cabin cable network. According to the actual use requirements and the number of satellite transition electrical connector settings, select the appropriate transition plan for the north and south cabin cable transition decoupling.

[0054] Figure 2 The satellite north and south cabin cable network decoupling method provided by the second embodiment of the present invention is shown. This embodiment is based on the first embodiment and further includes:

[0055] S107: If the cables do not have a coupling connection relationship or have been decoupled from different cabin cables through transition electrical connectors, determine whether there is a cable to be parsed with the next sequence cable number.

[0056] S108: If there are cables to be analyzed with the next sequence cable number, the coupling connection relationship analysis and processing of the cables to be analyzed are carried out in sequence until the analysis and processing of all cables in the cable network contact table are completed. That is, it is determined whether the currently processed cable is the last cable in the analyzed cable network contact table. If not, the cables of the next sequence are analyzed in the order of cable numbers; if so, the processing flow ends.

[0057] To sum up, the satellite north-south cabin panel cable network decoupling method provided by the present invention can quickly analyze and locate the cables with north-south cabin coupling connections among the numerous single machines and electrical connectors of the satellite, and provide transition coupling solutions for different application scenarios, thereby achieving the purpose of shortening the design time of the north-south cabin panel decoupling of the satellite cable network. At the same time, it greatly reduces the complexity of the relationship between cable branches, alleviating the difficulty of the route and laying of the cable network during the satellite assembly process.

[0058] The method according to the present invention can be implemented on a computer as a computer-implemented method, or implemented in dedicated hardware, or implemented in a combination of the two. The executable code or part thereof for the method according to the present invention can be stored on a computer program product. The example of a computer program product includes a memory device, an optical storage device, an integrated circuit, a server, online software, etc. Preferably, the computer program product includes a non-temporary program code component stored on a computer-readable medium so as to perform the method according to the present invention when the program product is executed on a computer.
