Background technique

The satellite automatic test system is the core of the satellite comprehensive test ground support equipment. It is a large-scale distributed computer network system composed of test service software and test application software. The test service software provides test data processing, distribution, storage, ground equipment management and remote control instruction management services; the test application software completes the sending of remote control instructions, the setting of ground equipment, the real-time display of test data and test information, the query of test information and analyze. Through the information interaction between the software, the processing, display, analysis and evaluation of satellite uplink and downlink data are jointly completed. the

In the past, the test application software was aimed at the interface service provided by the test service software, and the interface module was implemented by itself. This implementation method has the following shortcomings: 

1) The test application software that needs to have the functions of command sending and telemetry data display needs to complete the complex communication protocol conversion with the test service software, which reduces the development efficiency of the software and increases the development cycle. the

2) The test application software that needs to have the function of querying and analyzing historical data needs to complete the communication with the test database (one of the test service software) and the analysis of the test data table structure. Due to the different types of test databases of different models, the table structure It is not the same, resulting in increased difficulty in software development and poor versatility. the

As satellite testing has higher and higher requirements for ground software, the development mode of previous testing application software has poor reusability and high coupling, which is not suitable for improving the automation level of satellite testing systems and cannot quickly respond to the development requirements of satellite testing application software. the

If the network connection is successfully established, the network connection is obtained. The handle is used for data communication with the test service software, and then automatically sends a check-in message to the test service software, receives the time calibration message from the test service software and completes the system time calibration, and simultaneously notifies the test application software that the network connection is successful, and then enters the step ( 5); If the network connection fails to be established, then inform the test application software of the failure type, then return to step (4), and continue to wait for the connection command of the test application software;

(5) The test application software sends a subscription request command to the data subscription service interface, and the message is sent to the test service software after being packaged by the data subscription service interface, and then enters step (6);

(6) The data subscription service interface receives the test data corresponding to the subscription request command forwarded by the test service software, the data subscription service interface unpacks the test data, returns the test data to the test application software after extraction, and then continues to execute the steps (6) Until the test application software actively requests to disconnect, so as to complete a data subscription process;

(7) The data query service interface waits to receive the network connection command of the test application software, the data query service interface identifies the type of test database to be accessed by the test application software, constructs the database network connection string, and then calls the connection to the monitoring port of the corresponding database The function applies to establish a network connection. If the network connection is successfully established, the handle of the connection is obtained for data communication with the database, and then enters step (8); if the network connection fails, the test application software is notified of the failure type, and then restarts Execute step (7) and continue to wait for the connection command of the test application software. the

(8) The test application software sends the type and parameter content of the required query information to the data query service interface, and the data query service interface translates the type and parameter content of these query information into SQL statements of one or more corresponding databases, and converts them Send it to the database for query operation, and at the same time wait for the return message from the database in a synchronous manner. If the return message from the database is received within the specified time, the return message will be unpacked, and the query result will be extracted and returned to the test application The software thus completes the query process of the test data, and then performs step (8) until the test application software actively requests to disconnect; if the return message from the database is not received within the specified time, the error code is returned to the test application software, and then perform step (8), until the test application software actively requests disconnection;
