Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of numerical control technology, and in particular to an automatic testing method and system for a numerical control system supporting manual intervention. Background Art

[0002] At present, the automatic testing method of CNC system mainly uses G instruction program as the input content of test case. When the test case is executed for the first time, it is first verified by manual testing. If it is executed correctly, a standard template data file of the test case is created. The template file records the instruction domain data generated during the execution of the test case. If the test case is executed again later, it can be detected whether the instruction domain data generated during the execution is consistent with the data in the template file. If they are consistent, the test case is executed correctly, otherwise it is executed incorrectly.

[0003] The main defects of the above-mentioned existing automated testing methods are that the input data items of the test cases are limited to G code files, and some common manual intervention operations of CNC systems during the execution of G code are not supported, such as switching processing modes (automatic, single-stage, manual), switching processing states (cycle start, feed hold), modifying G instruction parameters (tool compensation, coordinate system), manually moving the feed axis, etc. In fact, more CNC system software defects are generated during manual intervention operations, which indirectly reflects that the integrity of current CNC system automated testing is poor and the test coverage is low.

[0004] Therefore, how to improve the integrity and test coverage of automated testing is a technical problem that needs to be solved urgently. Summary of the invention

[0053] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other arbitrarily without conflict.

[0054] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0055] Embodiment 1

[0056] Figure 1 A flow chart of a method for automated testing of a numerical control system supporting manual intervention is provided in an embodiment of the present invention. This embodiment is applicable to situations where a numerical control system performs automated testing of test cases. The method can be executed by an automated testing system for a numerical control system supporting manual intervention.

[0057] like Figure 1 As shown, the method specifically comprises the following steps:

[0058] S101: Recording template data generated by test cases during manual testing.

[0059] It should be noted that in the embodiments of the present invention, there are two types of tests, namely manual testing and automatic testing. Manual testing is performed manually. When a test case is executed by the numerical control system in the numerical control device, it is manually determined whether the test process and test results meet expectations. Automatic testing is to simulate the numerical control panel, generate a test case script, and then control the numerical control device to perform the test by the automated test program.

[0060] The purpose of manual testing is to screen out test cases that meet expectations and record the data generated by the test cases during the testing process as template data.

[0061] The purpose of automatic testing is to determine whether the test case is suitable for the current CNC system. By comparing the test data generated by the test case in the automatic testing process with the template data generated by the test case in the manual testing process, it can be determined whether the test case is suitable for the current CNC system.

[0062] Manual testing does not use the simulated CNC panel, but is performed manually based on automatic test operations and manual intervention operations. Both manual testing and automatic testing involve the running of G code programs. Therefore, by matching different lines of G code programs in manual testing with those in automatic testing, and confirming that the template data and test data generated when each line of G code program is running are compared, it can be determined whether the test case is suitable for the current CNC system.

[0063] Among them, the template data and test data include: the starting position of the operation point, the end position, the motion trajectory, the moving speed, the acceleration, the time, etc.

[0064] S102: Identify automatic test operations and manual intervention operations in the test case, and generate a test case script in a test case script generation area in the simulated numerical control panel.

[0065] In the embodiment of the present invention, the test case is actually a set of collections, including: test environment, operation steps, input data and expected results, etc. In order to verify whether the execution result of the test case is consistent with the expected result, it is necessary to provide the test case to the numerical control system in the numerical control device.

[0066] The operation steps in the test case include: automatic test operation and manual intervention operation.

[0067] In the embodiment of the present invention, the automatic test operation does not refer to the operation of the statements in the G code, but refers to the operation based on the G code program, including: the selection, loading, running, stopping and other operations of the G code program. The manual intervention operation refers to the operation based on the key events and the numerical control system, including: pressing the NC button, pressing the MCP button, restarting the numerical control system, updating the numerical control system version and other operations.

[0068] Automatic test operation actually refers to the related operations on the G code program. After the user selects a G code program, the automatic test system on the PC will automatically execute the G code program; the G code program can be a pre-written program or a manually input program.

[0069] Manual intervention operation actually refers to the human intervention in the code operation during the automatic operation of the G code program, such as switching the processing mode (automatic, single-stage, manual), switching the processing status (cycle start, feed hold), modifying the G command parameters (tool compensation, coordinate system), manually moving the feed axis, etc.

[0070] Figure 2 Schematic diagram of a simulated numerical control operation panel of a numerical control system automatic testing method supporting manual intervention provided by an embodiment of the present invention, such as Figure 2 As shown, the simulated CNC panel includes: CNC system interface display area, NC panel, MCP panel and test case script generation area.

[0071] Before identifying test cases, also include:

[0072] S211: The interface of the numerical control device is projected into the numerical control system interface display area through the remote desktop protocol.

[0073] S212: Mapping the NC keys of the numerical control device with the NC panel in the simulated numerical control panel.

[0074] S213: Mapping the MCP button of the numerical control device with the MCP panel in the simulated numerical control panel.

[0075] In the embodiment of the present invention, after the numerical control device is mapped to the numerical control system interface display area, a corresponding relationship between the NC panel keys and the NC keys is established, and a corresponding relationship between the MCP panel keys and the MCP keys is established.

[0076] When simulating the CNC panel to identify the test case, for each manual intervention operation in the test case, the simulated CNC panel will further identify whether it is an NC key operation of the CNC device or an MCP key operation, and correspond the NC key operation to the NC panel key in the simulated CNC panel, and correspond the MCP key operation to the MCP panel key in the simulated CNC panel.

[0077] Preferably, different NC panel buttons in the NC panel can be corresponded with different identifiers. Table 1 provides some NC operation contents and their identifiers. As shown in Table 1, a correspondence between NC panel buttons and identifiers is established. When the simulated numerical control panel recognizes an NC button operation, the corresponding NC panel button is first searched according to the correspondence between the NC panel button and the NC button; then the corresponding identifier is searched according to the correspondence between the NC panel button and the identifier, and then a manual intervention operation instruction is generated.

[0078] Table 1

[0079]

[0080] Preferably, different MCP panel buttons in the MCP panel can be corresponded with different identifiers. Table 2 provides some MCP operation contents and their identifiers. As shown in Table 2, a correspondence between MCP panel buttons and identifiers is established. When the analog numerical control panel recognizes the MCP button operation, the corresponding MCP panel button is first searched according to the correspondence between the MCP panel button and the MCP button; then the corresponding identifier is searched according to the correspondence between the MCP panel button and the identifier, and then a manual intervention operation instruction is generated.

[0081] Table 2

[0082]

[0083] In an embodiment of the present invention, the manual intervention operation in the test case can be decomposed into indivisible minimum sub-steps. Each time an NC button or an MCP button is pressed, a minimum sub-step is generated. Each minimum sub-step can correspond to an NC panel button or an MCP panel button and is represented by an identifier in a fixed format.

[0084] Furthermore, the test case script generation process is as follows:

[0085] S221: The simulation numerical control panel generates automatic test operation instructions according to the automatic test operation.

[0086] Automatic test operation instructions can be expressed in the format of "operation type (operation content, waiting time)". For example, "PROG_SEND (O13773.txt, 3000)" means sending the G code program named O13773.txt to the CNC system and waiting for 3s.

[0087] S222: The simulating numerical control panel generates a manual intervention operation instruction according to the manual intervention operation.

[0088] Manual intervention operation instructions can be expressed in the format of "operation type (operation content, waiting time)". For example, "NC_KEY (RESET, 10)" means pressing the reset button and waiting for 10ms; "MCP_KEY (CYCLE_START, 3000)" means pressing the cycle start button and waiting for 3s.

[0089] S223: The simulation numerical control panel determines the execution time of each instruction according to the operation time of each operation.

[0090] The test case includes various operation contents and the operation time of each operation content. By reading this information and restoring it in the way of program running, each instruction and the execution time of each instruction are obtained, and the playback of the test case is realized.

[0091] S224: In the test case script generation area of ​​the simulated numerical control panel, write each instruction and the execution time of each instruction in chronological order.

[0092] In the embodiment of the present invention, each line in the test case script, that is, an automatic test operation instruction or a manual intervention operation instruction, represents an atomic operation, and each atomic operation consists of three parts: operation type, operation content and waiting time.

[0093] Table 3 provides some operation types and their identifiers. As shown in Table 3, the operation types can be classified according to the different functions of the operation objects, including: key response, G code file sending and loading, CNC system restart and CNC system version update. Among them, G code file sending and loading corresponds to automatic test operation instructions; key response, CNC system restart and CNC system version update correspond to manual intervention operation instructions.

[0094] Table 3

[0095]

[0096] The operation content can be determined according to the operation type, see Table 1 and Table 2. Table 1 contains common operation content in NC_KEY type, and Table 2 contains common operation content in MCP_KEY type. The operation content is specifically represented by CNC system panel keys, G code file names, or CNC system standard upgrade package file names.

[0097] The waiting time indicates the interval time after the atomic operation is completed and before the next atomic operation starts to be executed, and the unit is ms.

[0098] The test case script can be loaded and executed by the automated test system. During the loading process, the automated test system parses the case script line by line from the beginning to the end of the file, converts each atomic operation into a line of executable code statements, and the automated test system executes the converted code statements in sequence to realize the playback of the test case in the numerical control device.

[0099] S103: Read the test case script and send instructions to the numerical control device; perform automatic testing according to the instructions and record the test data generated during the test.

[0100] After reading the test case script, the automated test system sends each instruction and the execution time of each instruction to the numerical control device through the Talnet protocol.

[0101] The key event receiving program in the numerical control device receives the manual intervention operation instruction and the execution time of the manual intervention operation instruction, and interprets it as a key event.

[0102] It should be noted that the underlying operating system of the numerical control device starts the key event receiving program, which calls the key event processing function of the operating system layer according to the manual intervention operation instruction. The key event receiving program can use<linux / input.h> The struct input_event in the simulation defines each key input event on the CNC panel. The defined key input event is written to the keyboard device file in the / dev / input / directory, which can trigger the key event processing function of the underlying operating system. At this time, the operating system notifies the CNC system process of the key event to realize the playback of the test case script.

[0103] The numerical control system in the numerical control device receives the automatic test operation instruction and the execution time of the automatic test operation instruction, as well as the key event, performs automatic testing, and records the test data generated during the testing process.

[0104] S104: Detect whether the test case passes the test based on the test data and template data. Specifically:

[0105] The line numbers of the G code program in the manual test and the generated template data are collected at a predetermined period, and each data segment of the template data is marked using the collected G code line numbers to form first instruction domain data.

[0106] The line numbers of the G code program in the automatic test and the generated test data are collected in the same cycle, and each data segment of the test data is marked using the collected G code line numbers to form second instruction domain data.

[0107] Since both manual and automatic tests involve the execution of G code programs, by matching different lines of G code programs in manual and automatic tests, and confirming that when each line of G code program is running, the corresponding template data and test data are compared to determine whether the test case is suitable for the current CNC system.

[0108] If the data in the first instruction domain is consistent with the data in the second instruction domain, it is detected that the test case has passed the test; if the data in the first instruction domain is inconsistent with the data in the second instruction domain, it is detected that the test case has not passed the test.

[0109] Preferably, the numerical control system in the manual test and the numerical control system in the automatic test can be the same system or different systems. Further, the numerical control system in the manual test and the numerical control system in the automatic test can be different versions of the same numerical control system.

[0110] The technical solution of an embodiment of the present invention discloses an automated testing method for a CNC system that supports manual intervention. First, in order to facilitate unified identification and management, the manual intervention operations in the test case are scripted; secondly, the recording of the test case script is realized through the remote desktop protocol and the user input on the simulated CNC panel; thirdly, the playback of the test case script is realized by utilizing the Talnet protocol and the built-in secondary development interface of the CNC system; finally, the correctness verification of the test case execution result is completed by combining the instruction domain big data technology.

[0122] Furthermore, the numerical control system in the numerical control device is used to receive automatic test operation instructions and the execution time of the automatic test operation instructions, as well as the key events, perform automatic testing, and record test data generated during the testing process.
