Detailed ways

In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In the related art, technicians use handheld cameras to record the assembly information of each device during the final assembly of the launch vehicle. When multimedia files need to be viewed on site, these files need to be imported from the camera to the computer, which is time-consuming and inefficient. When inspections or tracing of technical problems are required, a lot of manpower, material resources and time are required to find the on-site assembly information of a certain device. These multimedia records cannot be effectively managed and have low utilization rates.

FIG. 1 is a schematic diagram of a structure of a multimedia recording system provided by the present invention. As shown in FIG. 1 , the multimedia recording system 100 includes:

The data acquisition device 110 is electrically connected to the data processing device 120 and is used to collect assembly information of each device in the spacecraft to obtain multimedia records of each device;

The data processing device 120 is used to associate and store the multimedia records of each device with the nodes in the BOM tree of the spacecraft;

Among them, the BOM tree is determined based on the various devices in the spacecraft and the subordinate relationships between the various devices.

Specifically, the spacecraft in the embodiments of the present invention are various types of aircraft that perform specific tasks such as exploring, developing, and utilizing space and celestial bodies, including launch vehicles, artificial satellites, space shuttles, and space stations.

When a spacecraft is being assembled, it is necessary to record the assembly information of each device in a multimedia manner to facilitate on-site inspection or later problem tracing. The equipment here includes the various functional devices of the spacecraft, as well as the connectors that connect the various functional devices. The assembly information is the status of each device before and after installation, installation process records, and other information in the process of connecting the various functional devices to form a spacecraft. For example, for any connector, the assembly information may include the connector code, connector installation requirements, whether the connector is properly plugged in, connector connection status, and connector connection post-processing (heat protection treatment).

Multimedia records are files such as images, videos, and audios that record device assembly information. Therefore, the data acquisition device 110 may be a multimedia acquisition device such as a camera.

When the data acquisition device 110 acquires the assembly information of each device in the spacecraft and obtains the multimedia record of each device, the multimedia record of each device is sent to the data processing device 120. The data processing device 120 associates and stores the multimedia record of each device with the node in the BOM tree of the spacecraft.

BOM (Bill of Material) is a file that converts the composition of equipment and the materials involved into a data format that can be recognized by computers. In other words, it describes the equipment structure in a data format and is a device structure data file that can be recognized by computers. The BOM tree of a spacecraft refers to a file that uses a tree structure to represent the equipment structure of a spacecraft. The equipment structure of a spacecraft can be decomposed and the BOM tree of a spacecraft can be created based on the various devices and the subordinate relationships between the various devices.

Taking a three-stage launch vehicle as an example, the rocket can be divided into the first stage, the second stage and the third stage, wherein each stage includes an attitude control engine and a track control engine. Then the three-stage launch vehicle can be taken as the first-stage node, each stage as the second-stage node, and the engine as the third-stage node. According to the subordinate relationship of each device, the connection relationship between the nodes is constructed to obtain the BOM tree of the rocket. After the assembly information of each device of the rocket is collected by a data acquisition device, a plurality of multimedia records are obtained, and these multimedia records are associated with the corresponding devices, so that each device and the multimedia records of each device can correspond one to one, thereby realizing structured storage. The association relationship between the multimedia record and the BOM tree can be recorded in the form of a two-dimensional table. For example, when it is necessary to query a certain attitude control engine in the rocket, the multimedia record corresponding to the attitude control engine can be quickly retrieved through the two-dimensional table.

The data acquisition device 110 may be composed of a general camera for general scenes and an endoscope camera for special scenes. The endoscope camera is used to perform multimedia acquisition of assembly information of equipment inside the spacecraft. For example, for a component installed in a pipeline, the endoscope camera may be inserted into the pipeline to acquire the installation image or installation video of the component.

The data processing device 120 may be a desktop computer, a laptop computer, or a tablet computer installed at the assembly site of the spacecraft.

The multimedia recording system provided by the embodiment of the present invention collects assembly information of each device in a spacecraft through a data collection device to obtain multimedia records of each device, and associates and stores the multimedia records of each device with nodes in a BOM tree of the spacecraft through a data processing device, so that the multimedia records correspond to each device in the spacecraft one-to-one, so that the multimedia records are effectively stored and managed, which solves the technical problems in the prior art that the recording of assembly information of each device of the spacecraft is relatively scattered and the utilization efficiency is low, improves the efficiency and accuracy of querying spacecraft assembly information through multimedia records, improves the data utilization rate of multimedia records, and improves the efficiency of solving spacecraft assembly problems.

Based on the above embodiment, the data processing device includes:

A BOM navigation module, electrically connected to the control module, for creating a BOM tree for the spacecraft using various devices in the spacecraft as nodes and the subordinate relationships between the various devices in the spacecraft as edges;

A control module, electrically connected to the storage module, for associating the multimedia records of each device with the nodes in the BOM tree respectively;

The storage module is used to store multimedia records and BOM trees of various devices.

Specifically, from a functional point of view, the data processing device may include a BOM navigation module, a control module and a storage module.

The BOM navigation module is used to create a BOM tree for a spacecraft with each device in the spacecraft as a node and the subordinate relationship between each device in the spacecraft as an edge. In addition, the BOM navigation module can also be used to provide users with a custom navigation item function, so that users can quickly query the multimedia records of the installation or operation of each device in the spacecraft through the BOM navigation module. The implementation of the BOM tree is based on the storage structure of a two-dimensional table to realize the storage and access of the tree.

The implementation method includes the following steps:

Step 1: Create the storage structure of the BOM tree

Taking each device in the spacecraft as a node, the parent node of each node is determined according to the subordinate relationship between each device, and a BOM tree is created. The storage and access of the BOM tree are realized through the storage structure of a two-dimensional table, as shown in Table 1:

Table 1 BOM based on table storage structure

Serial number Field Name type meaning Remark 1 ItemID INT Node identification number Counting starts from 1 2 ItemParnetID INT ItemID's parent node ID The default value of the root node is 0 3 ItemName TEXT Node Name

Step 2: Load and display the tree node 2D data

FIG2 is a flow chart of the BOM tree loading and display method provided by the present invention. As shown in FIG2, the stored tree node information is loaded from the table into the memory, a temporary storage node container MapItems is created, and the data is processed one by one. If the field ItemParnetID of the node is 0 or does not exist, a new parent node is created; if it exists, the new node is used as the child node of the node. This cycle is repeated until each piece of data is processed. After processing, it can be displayed on a display connected to the data processing device.

Step 3: Save node data to a two-dimensional table

FIG3 is a flow chart of the BOM tree saving method provided by the present invention. As shown in FIG3 , to save the tree nodes, firstly, the node information is recursively stored in the container vItemInfo according to the recursive method, and finally, all the node information of the container vItemInfo is saved in the data table.

The control module is used to associate the multimedia records of each device with the nodes in the BOM tree. For example, when obtaining a video or image of any connector in the spacecraft during installation, in response to the user's operation, the node corresponding to the connector is determined in the BOM tree, and then the video or image is associated with the node, for example, in a key-value pair manner, with the node name of the node as the key and the storage address of the video or the image as the value.

The storage module is used to store multimedia records and BOM trees for each device. For example, for any connector, the corresponding multimedia record includes the connection scene image of the connector. When storing, it can also store information such as the connector code, connector, connector requirements, whether it is plugged in place, whether there are heat protection requirements, heat protection images, notes, etc., as shown in Table 2:

Table 2 Connector storage information table

Serial number Field Name type meaning Remark 1 ItemID INT Node identification number Display ItemName 2 ConectorCode char Connector code 3 Conector char Connectors 4 ConectorReq TEXT Connector requirements 5 Isok BOOL Is the connection in place? 6 ConectorPhoto TEXT Connector connection scene image 7 isProtectHeat BOOL Is there any heat protection requirement? 8 ProtectHeatPhoto TEXT Heat protection image 9 Remark TEXT Remark
