[0065] Example

[0066] like Figure 1As shown, the present invention is a test system suitable for a launch vehicle test launch process, comprising a binding data reading module, a test launch process organization module, a test launch operation execution module, a custom operation interface module, and a network execution interface module. The binding data reading module is used to read process binding data and test operation data from a file, the test launch process organization module is used to group multiple test operations into various test items, the test launch operation execution module is used to load and process various test operations, the custom operation interface module is used to create a custom operation function, and the network execution interface module is used to execute device interface data processing operations.

[0067] The binding data reading module uses a universal method to read the test process binding data and test operation data from the data file. Each data includes the test operation name, network sending interface name, test operation code and sending data. The module first completes the sequential reading of local data files stored in formats such as xml, txt, and dat, and then further converts them into a universal string list data format. Each line of content in the local data file is stored in a hash table format, and all the content in a file is stored in a list consisting of hash tables of all rows. The hash table key value is the attribute name of the string type, and the data value uses the C++ general data type.

[0068] The test launch process organization module completes the test process organization according to the process binding data, and controls the start and end of the process, and the start and end positions of the control process execution. This module reads the data list stored in the module according to the binding data, and further processes it into sequentially arranged test operation information to complete the test process loading. Each processed test operation contains information such as the operation name, operation parameters, and the sent qualified mark. Then, according to the user's input in the software interface, select the start position of the test process and the stop position of the test process. After the interface input confirms the start of execution, all test operation information is traversed in turn and sent to the test operation processing module for execution. After all operations are executed or the user inputs the stop operation, the test process is stopped.

[0069] The test launch operation execution module first completes the loading of the operation dictionary according to the test operation data file input by the binding data reading module, wherein each operation contains information such as the operation name, operation parameters, execution external communication interface, and custom function, and the content in the dictionary is stored in a fixed test operation information data type. Further, according to the test operation information input by the test launch process organization module, the operation item with the matching name is found from the operation dictionary, and the custom operation interface execution function and the virtual function of each network execution operation interface are executed in sequence. When a certain interface has a test result returned or all interfaces have been executed, the test operation is exited, and the execution result and execution success mark are returned to the test launch process organization module.

[0070] The network execution interface module is used for external communication interface message processing operations, completing functions such as network message sending and receiving between the software and various test devices. The module has different forms such as TCP external communication interface, UDP external communication interface, serial communication interface, etc., all of which inherit from the same general virtual interface object. Usually the software will have multiple different types of external communication interface instances, all of which are added to an execution list and are called by the upper-level test launch operation execution module. When the interface type changes or is added, only one external communication interface needs to be modified or added through the configuration file, without involving changes to other modules, so as to achieve universal and easy-to-expand interfaces when the software communicates with different test devices.

[0071] After receiving the test operation input, the network execution interface module will first determine whether it is an operation of this interface based on the execution interface information contained in the current operation. If it is an operation of this interface, the communication message will be sent according to the operation data of the data, and the execution result will be returned. If it is not an operation of this interface, it will be skipped directly and the next interface will be executed.

[0072] The custom operation interface module completes the creation of custom operation functions. This module binds a unique custom operation function pointer to each custom operation. When the test launch operation execution module detects that an operation is a custom operation, it will call the corresponding function pointer to complete the operation without executing the external communication interface. All custom operation functions have unified input and output parameters, that is, the test operation information type in the operation dictionary. In order to realize the generalization of different types of test operations, when a new test operation needs to be added, it only needs to modify the bound function implementation.

[0073] A test system for a launch vehicle test process of the present invention comprises the following steps:

[0074] Step 1: After the software is started, the binding data reading module reads the binding data from the local configuration file and processes the data into a common string list format that is easy for the software to read. If the reading is successful, it will continue to the next step, otherwise it will prompt an error. Further, the data is output to the test launch process organization module and the test launch operation execution module.

[0075] Step 2: The test launch process organization module completes the test process organization according to the input binding data. The test operations in the data are organized into test items in a certain order. Furthermore, the user sets the start and end positions of the process execution and controls the start of the process execution. The test operations in the process are read in sequence and output to the test launch operation execution module.

[0076] Step three, after receiving a test operation input from the process organization module, the test launch operation execution module sets the parameters of the operation according to the name, interface, attribute value, etc. of each test operation read from the binding data, and further cyclically calls the network execution interface and the custom operation interface to complete the test operation execution.

[0077] Step 4: After the network execution interface or the custom operation interface completes the operation execution, it will feed back the execution result to the test launch operation execution module. Further, the execution result is fed back to the test launch process organization module. When the module determines that the operation has been successfully executed, it will continue to execute the next operation in sequence, otherwise it will stop executing and prompt an error.

After reading the above content, it will be apparent to those skilled in the art that various modifications and substitutions of the present invention will occur.
