[0043] Embodiment 1

[0044] Figure 1 The digital test and interpretation system of a communication satellite transponder provided by the first embodiment of the present invention is shown, comprising a user operation control module 10, a comprehensive test module 20, a reading rule analysis control module 30 and a data processing module 40, wherein:

[0045] The user operation control module 10 is used to receive user operation instructions to trigger the generation of corresponding control instructions; wherein the control instructions include test control instructions, judgment rule control instructions and data analysis and processing control instructions; the comprehensive test module 20 is connected to the user operation control module 10, and is used to receive and respond to the test control instructions to control the test equipment 50 to generate an uplink excitation signal and transmit it to the satellite communication repeater 60, and receive the downlink test data fed back by the satellite communication repeater 60 through the test equipment 50; the judgment rule parsing control module 30 is connected to the user operation control module 10, and is used to receive and parse the judgment rule control instructions, and load the corresponding judgment rules into the data analysis and processing module 40 based on the judgment rule control instructions; the data processing module 40 is respectively connected to the user operation control module 10, the comprehensive test module 20 and the judgment rule parsing control module 30, and is used to receive the downlink test data in real time, and respond to the data analysis and processing control instructions to analyze and process the downlink test data through the judgment rules to generate corresponding judgment results.

[0046] The comprehensive test module 20 of this embodiment is directly connected to the test equipment 50, and can then send instructions through the comprehensive test module to remotely control the test equipment 50 and receive the test results of the test equipment 50 (i.e., the downlink test data fed back by the satellite communication repeater); the test equipment 50 includes but is not limited to a spectrum analyzer, a vector network analyzer, and a general ground inspection device.

[0047] The interpretation result is specifically presented in the form of a report, that is, the downlink test data is processed and analyzed by the data analysis and processing module based on the loaded interpretation rules to generate a corresponding interpretation result report.

[0048] The judgment rule analysis control module 30 is mainly used to control and manage the judgment rules, such as Figure 3 As shown, the judgment rules include indicator compliance judgment rules, data consistency judgment rules for each test stage, and test coverage judgment rules; the judgment rule analysis control module 30 of this embodiment stores the indicator requirements of the payload test items, the tightened indicators based on expert experience, and the test item coverage table. The judgment rule analysis control module 30 supports the addition, modification, deletion, and storage of judgment rules.

[0049] Preferably, the data processing module 40 is specifically used for: judging the compliance of the downlink test data with the preset indicators according to the indicator compliance judgment rules; judging the consistency of the downlink test data obtained in different test stages according to the data consistency judgment rules of each test stage; and judging the coverage of the actual test items of the downlink test data with the target test items of all test configurations in the predetermined test item coverage table according to the test coverage judgment rules.

[0050] Among them, when analyzing and processing the downlink test data based on the indicator compliance judgment rule, the preset indicator is determined based on the indicator requirements of the payload test project, that is, the preset indicator refers to the standard indicator that meets the requirements of the test project; the data processing module 40 determines the processing logic for the compliance judgment of the downlink test data according to the loaded indicator compliance judgment rule and judges the downlink test data according to the determined processing logic. For the same test configuration, the test results in different test stages should not be too different, otherwise the difference in the results needs to be analyzed even if the indicator requirements are met; for this, the data processing module 40 compares the downlink test data obtained in different test stages based on the loaded data consistency rules of each test stage to determine the consistency by comparing the results. The data processing module 40 of this embodiment can also perform test coverage analysis based on the test coverage judgment rule. The test coverage analysis takes into account the missing test items caused by abnormal shutdown of the machine, human operation errors, etc., and is a means of guaranteeing abnormal working conditions, ensuring the comprehensiveness and adequacy of the test, and avoiding problems such as insufficient testing.

[0051] Optionally, performing coverage judgment on the actual test items of the downlink test data and the target test items of all test configurations in a predetermined test item coverage table according to the test coverage judgment rule includes:

[0052] S1. According to a predetermined test item coverage table, each test configuration and its required test items are read from the current test configuration library one by one to form a test set.

[0053] S2. Generate a measured set consisting of tested items according to the actual test situation of receiving the downlink test data in real time.

[0054] S3. Determine whether the difference between the set to be tested and the measured set is an empty set.

[0055] S4. If the difference between the set to be tested and the measured set is not an empty set, the difference between the set to be tested and the measured set is used as a new set to be tested, and the process returns to repeat steps S2 to S3.

[0056] S5. If the difference between the set to be tested and the measured set is an empty set, return to step S1 to read the next test configuration and its required test items from the current test configuration library one by one to form the set to be tested, and repeat steps S2 to S3 until all test configurations and their required test items in the current test configuration library are read.

[0057] In specific implementation, the data processing module 40 performs test coverage analysis based on the algorithm logic determined by the test coverage judgment rule. The algorithm logic of the test coverage analysis in this embodiment is as follows: suppose that all test configurations in the test item coverage table constitute a full set U, of which there are L test configurations, and each test configuration is a subset G i (1≤i≤L), the test items required for the test configuration constitute the elements of the set G i , the sequence of steps is:

[0058] (1) Initialize the algorithm and read the i=1th test configuration and its required test items in the current test configuration library, i.e., set G1. Let the input set to be tested of the algorithm be M=G i .

[0059] (2) After the test is completed, the measured set N is generated based on the actual test situation.

[0060] (3) Determine whether the difference between the set to be tested M and the measured set N is an empty set; if the difference is not an empty set, set the set to be tested M = MN, and repeat steps (2) to (3); if the difference is an empty set, execute step (4).

[0061] (4) Let i=i+1, and determine whether i≤L. If i≤L, repeat steps (2) to (3); otherwise, terminate the test coverage analysis algorithm immediately.

[0062] Preferably, the user operation control module 10 is also used to provide a human-computer interaction interface, and the human-computer interaction interface is used to generate corresponding control instructions according to the user's trigger operation. The human-computer interaction interface is specifically used to authorize the user to log in, and the authorized user generates corresponding test control instructions, judgment rule control instructions, and data analysis and processing control instructions, etc. through corresponding trigger operations on the human-computer interaction interface according to needs; further, the user operation control module 10 receives the judgment result fed back by the data processing module 40 and visualizes the judgment result, replays the judgment result, and processes the judgment result through the human-computer interaction interface; the user operation control module 10 is also used to manage and control the judgment rules pre-stored in the judgment rule analysis control module.

[0063] like Figure 2As shown, the user operation control module 10 is specifically used to realize the control function of the system, and its functions may include human-computer interaction function, management and control function of interpretation rules, command editing and sending function, and interpretation result report management function. Among them, the human-computer interaction function facilitates the operation and use of other tools, the interpretation rule management and control function is specifically divided into interpretation rule addition, interpretation rule deletion, and interpretation rule update, etc.; the command editing and sending function is specifically divided into test control instructions, interpretation rule control instructions, and data analysis and processing control instructions. The interpretation result report management function is specifically divided into interpretation result visualization, interpretation result storage, interpretation result playback, and interpretation result deletion.

[0066] S101: The system is initialized to load the test configuration, the test item coverage table and the judgment rule library; Step S101 is specifically initialized by the digital test judgment system of the communication satellite transponder, and the system initialization includes loading the test configuration, the test item coverage table and the judgment rule library; the judgment rule library pre-stores a number of processing rules, such as indicator compliance judgment rules, data consistency judgment rules for each test stage, and test coverage judgment rules.

[0067] S102: Reading corresponding test configurations from the test configuration library in sequence;

[0068] S103: parsing the test items and interpretation rules required by the test configuration into test control instructions and interpretation rule control instructions respectively; combining Figure 5 It can be seen that the generated test control instructions and judgment rule control instructions are sent to the comprehensive test module and the judgment rule analysis control module respectively.

[0069] S104: Control the test equipment to generate an uplink excitation signal according to the test control instruction and transmit it to the satellite communication repeater, and receive the downlink test data fed back by the satellite communication repeater through the test equipment; specifically, the test equipment is controlled to generate an uplink excitation signal according to the test control instruction through the integrated test module, and the uplink excitation signal is sent to the satellite communication repeater, and the satellite communication repeater transmits the fed back downlink test data to the integrated test module through the test equipment.

[0070] S105: Loading corresponding interpretation rules from the interpretation rule library according to the interpretation rule control instruction; specifically, the interpretation rule analysis control module controls the data analysis processing module to load corresponding interpretation rules according to the interpretation rule control instruction.

[0071] S106: Analyze and process the downlink test data received in real time according to the loaded judgment rules to generate corresponding judgment results. The data analysis and processing module simultaneously receives the downlink test data of the comprehensive test module, and analyzes the downlink test data based on the loaded judgment rules to obtain corresponding judgment results; no human intervention is required and the judgment results are obtained quickly, which reduces the manual operation cost, saves the test time, and improves the test quality.

[0072] Furthermore, after step S106, the method further includes:

[0073] S107: Based on the test item coverage table, determine whether all test items corresponding to the test configurations have been executed; specifically, the test coverage analysis algorithm of the above embodiment can be used to determine whether all test items corresponding to the test configurations have been executed; please refer to the contents of the above embodiment for the test coverage analysis algorithm, which will not be repeated here.

[0074] If the test items corresponding to all test configurations have not been executed, return to the step of reading the corresponding test configurations in sequence from the test configuration library to read the test configurations of the next order for test interpretation, that is, return to step S102 to reselect the test configurations of the next order and enter the subsequent steps S103 to S107. This process is carried out synchronously with the real-time reception of downlink test data. Therefore, in the subsequent repetition of steps S102 to S107, the downlink test data will be synchronously updated for analysis until the test items corresponding to all test configurations have been executed. If the tests of all test configurations are completed, the digital test interpretation task is terminated.

[0075] In summary, the present invention realizes the integration of testing and interpretation, greatly reduces the manual operation cost, improves the testing and interpretation efficiency, and saves testing time; at the same time, through specific interpretation rules, the interpretation ability and interpretation accuracy of identifying abnormal transponder performance, as well as the ability to handle abnormal test conditions, are greatly improved, thereby improving the test quality.
