Description

Technical Field

[0001] The present invention relates to the field of digital product design, and specifically, to a three-dimensional wiring design method and system for satellite thermocouples. Background Art

[0002] A thermocouple is a temperature measuring sensor used in the satellite thermal test process, and it needs to be removed after the thermal test is completed. In actual use, the thermocouple is generally pasted and assembled on a single machine in the satellite cabin and is connected to a plug for collecting data outside the cabin through a cable. The satellite thermocouple wiring design is to design the wiring of the thermocouple from the pasting point in the satellite cabin to the plug outside the cabin. Generally, dozens to hundreds of thermocouples are used in a single thermal test, and the main cost of the thermocouple wiring is mainly determined by the length of the connecting cable. Since the length of the cable required for each thermocouple is different, through a more accurate wiring design, the actual required length of the thermocouple cable can be obtained, thereby reducing waste and lowering costs.

[0003] The satellite thermocouple layout design is similar to the satellite cable design. The Chinese patent "Satellite Low-Frequency Cable Design System, Design Software Architecture and Design Method" (Publication No.: CN106294929A) provides a satellite low-frequency cable network design system, design software and design method. This patent realizes the integrated layout and design of the cable. By conducting a detailed design of each cable on the computer-aided design model, the processing drawing of the cable and the three-dimensional routing path diagram for human-computer interaction are finally obtained. The above method is very suitable for the cables that need to go to space with the satellite. Each cable has an accurate length, thus achieving the purpose of reducing the weight of the products going to space. However, for the thermocouples that are only used once in the thermal test process, it is necessary to optimize the wiring design method and the accurate design results to achieve the purpose of improving the design efficiency, reducing losses and lowering costs.

[0004] Currently, no patents on the satellite thermocouple layout design have been found. Summary of the Invention

[0220] Embodiment 6 is a preferred example of Embodiment 1, which is used to illustrate the present invention more specifically.

[0221] Figure 1 It is a schematic diagram of the composition of a satellite thermocouple 3D wiring design system constructed according to the present invention. The system is realized based on the secondary development of 3D modeling software, and includes a data preparation module, a partition definition module, a bundle point design and management module, a thermocouple assembly and management module, a cable path design module, and a design result output module. The following is a specific explanation of each of them.

[0222] The data preparation module is used to derive the thermocouple wiring design model for subsequent wiring and sort out the thermocouple list information table according to the specified template. The thermocouple wiring design model is derived based on the three-dimensional design model of the entire satellite. It contains all the information of the three-dimensional design model of the entire satellite and an empty skeleton module for storing the routing geometric information generated by subsequent designs; the thermocouple list contains attribute information such as thermocouple number, equipment code, equipment name, thermocouple assembly position, affiliated partition, and connected plug number. The list information template and examples are as follows Figure 2 as shown.

[0223] The partition definition module is used to identify the regional surface on the thermocouple wiring design model, create partitions, and associate one or more regional surfaces with the partitions. Combining Figure 3 , the process and method for identifying the main surface of the region are as follows:

[0224] (1) Referring to the thermocouple list, find the assembly surface Fac where the thermocouple is located on the thermocouple wiring design model;

[0225] (2) Select Fac (or auxiliary surface Fn), and the system automatically calculates the distance L1 from the center point to the farthest point on the surface edge;

[0226] (3) Determine whether L1 is greater than the given standard value Lmax. If L1 is greater than Lmax, go to (4); if L1 is less than or equal to Lmax, go to (5);

[0227] (4) Create two or more auxiliary surfaces F1, F2......Fn on Fac to replace Fac, and then go to (2) for calculation;

[0228] (5) Identify the Fac or Fn that meets the determination requirements as the main surface of the region.

[0229] After the definition of the main surface of the region is completed, corresponding partitions are created on the three-dimensional model according to the partition information in the thermocouple list information, and then the main surface of the region is associated with the partition where it is located. One partition can contain multiple main surfaces of the region, and one main surface of the region belongs to only one partition.

[0230] The bundle point design and management module automatically creates partition bundle points in the partition, adjusts the position of the bundle points as needed, and edits the attribute information of the bundle points. When the position of the automatically generated partition bundle point in the three-dimensional model is not conducive to actual bundling, the position of the bundle point needs to be adjusted. Editing the attribute information of the bundle point mainly includes renaming the number and name of the bundle point, etc.

[0231] The thermocouple assembly layout and management module assembles thermocouples in the partition as needed and designs the wiring between the thermocouples and the bundle points, and calculates the common design length of all thermocouples to the bundle points in this partition. Combining Figure 4, the calculation steps for the common design length of thermocouples within a partition are as follows:

[0232] (1) Select 1 thermocouple farther from the bundling point within the partition for assembly, design the wire routing between the thermocouple and the bundling point, and the system calculates the wire routing length Lr;

[0233] (2) The system automatically calculates the automatic wire routing length Lf from the farthest point at the partition edge to the bundling point. Lf has considered the avoidance of other models within the partition during the calculation process;

[0234] (3) Take the larger value L (L = Max{Lr, Lf}) of Lr and Lf as the wire routing length from all thermocouples within the partition to the bundling point; when the distance from the thermocouple to the bundling point is significantly less than the distance from the partition edge to the bundling point, the wire routing design calculation of Lr can be omitted and directly use Lf as the value of L.

[0235] The cable path design module groups the partitions, assembles the three-dimensional model of the plug, and designs the wire routing from the bundling point to the plug. The partition grouping and plug assembly module creates groups on the three-dimensional model according to the thermocouple list information and adds the affiliated partitions. One group corresponds to one plug; the three-dimensional model of the plug is assembled at the corresponding spatial position in the three-dimensional design model of the thermocouple according to the actual position of the plug. The cable path design module designs the cable wire routing from the partition bundling point to the corresponding plug, defines some key points on the cable wire routing as path control points on the three-dimensional model, and then generates the three-dimensional model of the cable from the bundling point, control points to the plug in sequence, and supports directly referencing the completed cable model, finally completing all cable wire routing designs.

[0236] The design output module outputs the completed thermocouple information and the plane branch diagram of the thermocouple wire routing. As Figure 5 shown in the thermocouple information diagram, in the last column, such as "4386(4500)", "4386" is the design length value, and "4500" is the closest standard length value selected upward in the library; as Figure 6 shown in the output cable branch diagram, this branch diagram can guide the manufacture and bundling of the cable.

[0237] Combined with Figure 7 , the three-dimensional cable routing design method for satellite thermocouples includes the following steps:

[0238] Step 1: Sort out and form a thermocouple layout information list, read in the three-dimensional design model of the entire satellite and derive a thermocouple cable routing design model based on the entire satellite design model;

[0239] Step 2: On the thermocouple cable routing design model, identify and define the surface area where the thermocouple needs to be assembled with reference to the thermocouple layout list information, and combine one or more surfaces into a partition according to certain rules;

[0240] Step 3: Creation, position adjustment and attribute information management of the bundling points of the thermocouple wiring within the partition;

[0241] Step 4: Read in the thermocouple list information and associate each thermocouple with its corresponding partition. Plan the wiring between the thermocouple and the bundling point as needed, and calculate the common design length L1 of all the thermocouples within the partition to the bundling point;

[0242] Step 5: Assemble the plug, and design the wiring between the partition bundling point and the connected plug, with the wiring length being L2;

[0243] Step 6: Calculate the thermocouple length information L = L1 + L2, and output the thermocouple design result, including the thermocouple report and the flattened cable branch diagram.

[0244] In summary, the three-dimensional wiring design system and method for satellite thermocouples provided by the present invention can achieve fast and accurate wiring of thermocouples, and finally generate the reports and branch diagrams required for the thermocouple wiring design, which can effectively reduce the waste of thermocouple connection cables and reduce the cost of satellite development.

When the partition contains multiple main surfaces of the area, the clustering point is located on the main surface of the area closest to the middle. The clustering point refers to the centralized bundling point of all the connecting cables of the thermocouples in the partition. The cluster point position and information management module adjusts the position of the created cluster point and edits the information, including the number and name of the cluster point; Thermocouple and partition association module reads in the thermocouple list information and automatically associates it with the partition defined in the 3D model according to the partition information where the thermocouple is located; Thermocouple assembly and bundle point path design module. Select the thermocouple that is the farthest from the bundle point and at the outermost edge in this partition as needed, design the wire routing from this thermocouple to the bundle point, and obtain the wire length Lr; when the distance between the thermocouples in the partition and the edge of the curved surface is greater than the preset value, do not actually assemble the thermocouples and design the wire routing; automatically calculate the longest wire routing length Lf from each point on the main surface of the area in the partition to the bundle point; the module uses the larger value of Lr and Lf as the cable length in this partition, and if there is no Lr, directly use Lf as the cable length in this partition; Partition grouping and plug assembly module creates groups on the 3D model according to the thermocouple list information, and adds the partitions to the corresponding groups. One group can contain multiple partitions, one partition belongs to only one group, and the thermocouples on all partitions contained in one group are connected to the same plug, and one grouping corresponds to one plug; assemble the 3D model of the plug at the corresponding spatial position in the 3D design model of the thermocouple according to the actual position of the plug; Cable path design module designs the cable routing from the partition bundle point to the corresponding plug, defines the key points on the cable routing on the 3D model as path control points, and then sequentially connects the bundle point, each control point and the plug to generate the 3D model of the cable, and supports referencing the existing 3D model of the cable to complete the design of all cable routings; the path control points are some key points on the cable routing path; Cable flattening branch diagram output module flattens the 3D model of the cable into a 2D branch diagram for output, and marks the length information on each branch; Thermocouple statistical report output module outputs a statistical report containing thermocouple numbers, cable lengths, locations, and connected plug numbers.
