Description

BACKGROUND OF THE INVENTION

[0002] From the single-unit acceptance and delivery to the overall satellite assembly in the satellite factory, the overall satellite factory acceptance test, and then to the launch, various ground tests need to be experienced. The main test stages involved in the satellite development process generally include single-unit acceptance tests, overall satellite stage tests, environmental experiment stage tests, satellite ground station TT&C docking tests, launch site tests, etc. In order to complete the test work at each stage, test instructions suitable for different stages need to be sent. During the single-unit acceptance and delivery, CAN instructions need to be sent to the lower computer by simulating the satellite service through the bus monitoring software. During the overall satellite stage, remote control instructions need to be sent to the satellite by simulating the ground TT&C station. During the docking experiment stage between the satellite and the satellite ground TT&C station, complete remote control frame full-frame instructions need to be sent. The basic format of the satellite instructions is fixed characters plus valid data codes plus checksums as specified by the protocol. For CAN instructions, its basic format is the arbitration field, the control field plus the valid data field. The arbitration field and the control field are 4-byte fixed characters. The valid data field contains 1 byte of data packet identification, four bytes of valid instructions, and 1 byte of checksum SUM. SUM is the cumulative sum of the data packet and the valid bytes; for remote control instructions, its format is basically the leading header plus the data field plus the error control field. The leading header includes information such as the satellite version number and the spacecraft identification frame length. This part is fixed characters; the data field is the actual valid instruction code, and the length is generally fixed. If the valid characters are not enough for the fixed length, characters need to be filled; the error control field is the exclusive OR sum checksum; the remote control frame has a higher-level protocol encapsulation on top of the remote control instruction. The remote control frame format is generally the satellite synchronization word, the mode word, the remote control injection data, and the CRC checksum;

[0003] As the management center of the satellite mission, the on-board computer needs to communicate with each lower computer through the CAN bus; the TT&C ground station and the satellite perform information interaction tasks such as telemetry, remote control, and data transmission according to the specified interface protocol; it can be seen that from the single unit to the subsystem and then to the overall satellite, different-level tests need to generate test instructions according to different communication interface protocols to complete the corresponding test tasks. Regardless of the test instructions at which stage, the valid data of these instructions are 4-byte code instructions, also known as basic instructions. This basic instruction code is provided by the single-unit developer and is a command that allows external devices to perform relevant operations on this single unit, and it is the content that will cause the single unit to generate an actual response. Different formats of test instructions are each encapsulated on the basis of the basic instruction.

[0004] Currently, the test instructions have the following problems:

[0005] 1) The generation of the current instruction does not consider integrating each test stage. For example, the single-machine acceptance test belongs to the scope of work of the subsystem designers, the overall satellite test belongs to the scope of work of the overall designers, and the ground TT&C docking also belongs to the scope of work of the overall designers. In the previous working methods, each stage was independent of each other, the transfer of test instructions had no inheritance and was not traceable, and the frequent changes in the technical status during the development brought great challenges to the management of the final test instruction version.

[0006] 2) The current test instruction generation method does not achieve batch processing of test instructions for the entire satellite development stage. Specifically:

[0007] The existing tools can meet the generation of single test instructions without batch processing. Even if batch processing is carried out, it is only for the remote control instructions in the overall satellite test stage, and the test instructions in the single-machine acceptance stage and the full-frame instructions of the remote control frames required for docking with the satellite TT&C ground station are not considered. That is, a batch processing method for the remote control information in the entire satellite development stage cannot be realized, which severely restricts the current remote control information processing efficiency.

Concatenate the four-byte basic instruction code and the check code corresponding to the four-byte basic instruction code to obtain the valid test instruction corresponding to the four-byte basic instruction code until the valid test instruction corresponding to each four-byte basic instruction code is obtained.

[0047] The present invention can batch generate valid test instructions, greatly improving the efficiency of instruction generation and also solving the problem of instruction version control caused by frequent changes in the technical state.

[0048] Optionally, in the above technical solution, it further includes:

[0049] S4. Generate a remote control instruction list according to the valid test instruction that is a remote control instruction, and generate a full-frame remote control instruction corresponding to each remote control instruction in the remote control instruction list.

[0053] The technical effects of the present invention are as follows:

[0054] 1) It can provide guidance for testers and guide testers to complete the production of commands for the entire process of satellite development. For satellite comprehensive testers, they generally do not have access to the previous acceptance and subsequent docking tests, and their work has strong limitations. Through this method, the work scope of satellite comprehensive testers can be extended to acceptance tests and docking tests, broadening the work scope of satellite comprehensive testers and improving the satellite comprehensive test ability.

[0055] 2) It has strong versatility and ease of use. By copying the 4-byte commands in the ICD file into the software and clicking the button, the required test commands can be generated.

[0056] 3) The efficiency of generating test commands is greatly improved. For example, it used to take 5S to generate one test command, and 500 seconds for 100 commands. Now, using the same time, not only can 100 commands be batch-generated within the time of one command, but also the test commands required for each stage can be generated, greatly improving the test efficiency.

And the test commands for each stage are integrated into one page, with clear corresponding relationships and traceability, greatly improving the efficiency of command generation and also solving the problem of command version control caused by frequent changes in the technical status.
