All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1

The basic information configuration of the concurrent tasks generally comprises task types and task execution parameter association file information, and the basic information can be expanded according to task characteristics. In this embodiment, two task types, namely a test flow and a periodic query, are defined, concurrent task types can be expanded according to actual needs, and the task execution parameter associated file information is a corresponding csv file name and path.
And the concurrent task execution parameter configuration is different according to different task types. The test flow type is suitable for sequentially executing various 1553B instruction test items, the test items are distinguished in a configuration information mode, the configuration information is stored in a CSV file mode, each line is configured with 1553B message instruction sending and command return interpretation parameter information, a 1553B test configuration mode can be designed into a BC- > RT and BC < -RT message mode, and input parameters and test criteria of a 1553B communication test function are configured according to the BC- > RT and BC < -RT message modes. The periodic query task parameters comprise BC < -RT message related parameters and query period setting.
Preferably, the starting of concurrent task testing according to the configuration information includes:
extracting the concurrent task information from the concurrent task basic information, and creating and starting concurrent multithreading; the communication instruction test execution process is controlled by setting three control states of starting, suspending and continuing.
Specifically, concurrent task information in a task basic information ini file is extracted, multi-task concurrency is achieved by adopting a multi-thread technology, and concurrent multi-threads are created and started. The test thread completes test flow tasks such as 1553B time sequence test and the like, and comprises the steps of simulating BC to send BC- > RT write messages to realize sending test instructions, and simulating BC to send BC < -RT read messages to realize data read-back. And 3, simulating BC by a 1553B period telemetry task thread at a 20ms period to send BC < -RT read messages, and periodically acquiring telemetry data.
And controlling concurrent tasks, namely controlling the 1553B communication instruction test execution process by setting three control states of starting, suspending and continuing. When the test task is started, a 1553B test thread and a 1553B cycle telemetry task thread are started simultaneously, when the test process is suspended, firstly, the cycle telemetry task is locked by adding mutual exclusion to ensure that the cycle task is executed and completed, when the test process is suspended, logic locking is executed on a complete test item in the test thread to ensure that the test is executed and completed, then the suspension is executed, and when the test is started again, the mutual exclusion lock is released to continue executing subsequent tests.

and setting an interrupt service program, and protecting the whole process of the interrupt service function by setting a completion flag switch in the interrupt service program.
Specifically, a test application and drive separation layered decoupling mode is adopted for design, a 1553B communication instruction test function and a 1553B communication board card operation are separately designed, a drive layer processes a bottom hardware communication operation and a multi-task concurrent resource protection processing logic, reliable data concurrent communication is achieved, and a test application layer achieves execution time sequence and function logic of a 1553B test function.
And packaging the 1553B test board card driving interface function to realize application function decoupling, wherein the bottom layer interface is uniformly packaged into two functional interfaces of 1553 BSendBCtotRT and 1553 BRcvRTtoBC. Both threads may call the bottom two functional interface functions when performing 1553B communication operations.

When the process in each functional interface function is processed, firstly, a Mutex lock is opened, then a BC is simulated to send 1553B messages (RT- > BC and RT < -BC), the completion of the triggering execution of the interrupt service function is waited, a response message MsgA is read after the data of the response message is updated, the data is read from the extracted RT response message MsgA to complete a complete RT- > BC data reading process, the operation of reading the DataA data is completed, and finally, the Mutex lock is closed, and the operation is completed.
And setting an interrupt service program, wherein two functional interfaces 1553 BSendBCtotRT and 1553BRcvRTtoBC related to the 1553B message sent by the simulation BC interact data with an interrupt service function, and the interrupt service function executes the updating operation of the bottom layer data message. And a finishing mark switch is set in the interrupt service program to protect the whole process of the interrupt service function. Meanwhile, the data is updated by the bottom layer by adopting the interrupt service program, so that the MT data can be recorded in the interrupt service program.
Through the processing, correct message communication logic can be executed in the multithread scheduling process, correct time sequence of execution of each thread is shown in the following figure 2, a test thread sends RC- > BC read message MsgA at T0, an interrupt service function is triggered to execute data reading operation from a board card, the reading operation is finished at T1, the test thread A takes out valid data DataA, a remote measurement thread sends RC- > BC read message MsgB at T2, the interrupt service function is triggered to execute data reading operation from the board card, the reading operation is finished at T3, and the remote measurement thread B takes out the valid data DataB.
If the concurrency protection operation is not adopted, a data reading exception may occur, fig. 3 is a possible exception execution time sequence diagram of a multitask concurrency test RC- > BC read message based on 1553B communication, when an interrupt service function executes to send a message, the execution time sequence of each thread is shown in fig. 3, at a time point 1553B at T0, the test thread sends an RC- > BC read message MsgA to trigger an interrupt service function to read DataA from a board, when reading of DataA is not completed at a time point T1, 1553B telemetry thread B sends an RC- > BC read message MsgB, when reading of DataA is completed at a time point T2, 1553B telemetry thread B takes out exception data DataA (valid data is DataB), and at the same time, the MsgB message triggers the interrupt service function to read DataB from the board, and when reading of DataA is completed at a time point T3, 1553B test thread a takes out exception data DataB (valid data is DataA). Fig. 4 is another possible abnormal execution timing diagram of a multitasking concurrent test RC- > BC read message based on 1553B communication. When data is read during execution of the interrupt service function, the execution timing of each thread is shown in fig. 4, at a time 1553B at T0, the test thread sends an RC- > BC read message MsgA to trigger the interrupt service function to read data from the board, at a time T1, the test thread a takes out valid data DataA, at a time 155 2, the remote measurement thread sends an RC- > BC read message MsgB to trigger the interrupt service function to read data from the board, at a time T3, the RT message data is read when the read operation is not completed, and at a time 1553B, the test thread a takes out the non-updated abnormal data DataA (the valid data is DataB).
