The service performance integrated testing method of a polar ship communication and navigation system according to claim 1, characterized in that: The method for implementing step S3 is: Step S31: test data storage: storing the collected test data of the communication system equipment in step S21 and the test data of the navigation system equipment in step S22 in a test data storage unit; Step S32: test data analysis and evaluation and service performance grading: the test data described in step S2 is expanded and compared with the recommended service threshold and the minimum service threshold described in step S1. If the result indicator in the test data is greater than or equal to the recommended service threshold, it is marked as recommended; if the result indicator is less than the recommended service threshold but greater than or equal to the minimum service threshold, it is marked as qualified; if the result indicator is less than the minimum service threshold, it is marked as warning; Step S33: Based on the test data described in step S2, annunciate the disconnected communication mode and the satellite navigation mode with no signal as a warning; Step S34: Generate a test brief: Generate a test brief for the current cycle according to the hardware detection result in step S1, the test data result in step S2, and the service performance grading result in step S3; And send the test briefing back to the shore center.
4. A service performance integrated test system for polar ship communication and navigation systems is used to execute the method described in any one of claims 1 to 3, characterized in that: include: Configuration module, test module, processing module and visualization module; The configuration module includes a system detection unit, a hardware detection unit, a device operation detection unit and a test configuration unit. The system detection unit detects and identifies the types of devices of the communication system and the navigation system installed on the ship side; The hardware detection unit identifies the communication mode supported by the communication system device and the satellite navigation mode supported by the navigation system device; The device operation detection unit detects whether the devices of the system to be tested can operate normally, and marks the devices of the system to be tested that cannot operate normally with a warning mark; The test configuration unit sets a configuration file according to actual needs, and the configuration file includes: test content, test cycle, recommended service threshold and minimum service threshold; The test module includes a communication test unit for implementing ship-to-shore communication test on the communication system equipment and a positioning test unit for implementing satellite navigation positioning test on the navigation system equipment. The two units receive the test tasks of the corresponding types sent by the configuration module, determine the target system to be tested corresponding to the test tasks, control the target system to be tested to execute the test tasks, and obtain the service performance of the target system; The processing module comprises a test data storage unit, a test data analysis unit and a test report generation unit; The test data storage unit stores the test data acquired in the test module; The test data analysis unit compares the data obtained from the test module test with the recommended service threshold and the minimum service threshold in the test task, and marks a recommendation if the result indicator is greater than or equal to the recommended service threshold, marks a passing mark if the result indicator is less than the recommended service threshold but greater than or equal to the minimum service threshold, and marks a warning if the result indicator is less than the minimum service threshold; The test report generating unit generates a test report according to the hardware detection result, the test data and the service performance grading result; The visualization module includes a visualization unit and an early warning unit; The visualization unit displays various test results of the equipment of the system to be tested in the test briefing in a graphical or tabular form, supports sorting specific communication methods or navigation methods according to different indicators, and visualizes the service performance grading results of various communication and navigation methods: green marking is recommended; Standards that meet the standards are marked in yellow; The warning mark is red; the warning unit generates warning information for the specific communication method or navigation method with the warning mark, and displays the warning information.
