Detailed implementation manners

[0010] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0011] The terms "first", "second", etc. in the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein. In addition, the "and / or" in the present application means at least one of the connected objects, and the character " / " generally indicates an "or" relationship between the associated objects before and after. It should be noted that the data involved in the present application are all obtained under the premise of obtaining user authorization.

[0012] The following will describe in detail the technical solutions provided by each embodiment of the present application in conjunction with the drawings.

[0013] Figure 2 Schematic diagram of the process of a test method provided by an embodiment of the present application. As Figure 2 shown, the test method of the embodiment of the present application is applied to a conversion unit, and specifically may include the following steps: S201, receive the control instruction sent by the host computer. The control instruction is generated by the host computer according to the test process in at least one functional module of at least one test unit in the selected test project, and is generated according to the project test process.

[0014] In the embodiment of the present application, the execution subject of the test method of the embodiment of the present application is the conversion unit in the test device.

[0015] Figure 3 It is a schematic structural diagram of the test system of the embodiment of the present application, as Figure 3 shown. The test system of the embodiment of the present application includes: the device under test 3 and a test device connected to the device under test 3. The test device includes a host computer 4 and a conversion unit 5. The host computer 4 is connected to the device under test 3. The host computer 4 includes a test tool 41. The test tool 41 includes at least one pre-constructed test project. The test project includes at least one test unit. The test unit includes at least one functional module. The functional module is deployed with a test process corresponding to the function. The conversion unit 5 is respectively connected to the host computer 4 and the device under test 3. The host computer 4 may specifically include, but is not limited to, a mobile phone, a tablet computer, a desktop computer, a portable notebook, etc.

[0016] In the embodiment of the present application, the conversion unit 5 replaces the injection molding machine control system 1 in the related art Figure 1 and is communicatively connected to the test tool 41 in the independently developed host computer 4 and communicatively connected to the device under test 3. The conversion unit 5 communicates with the test tool 41 in the host computer 4 through a communication protocol (for example: Ethernet, ModebusTCP). The test tool 41 in the host computer 4 is communicatively connected to the servo driver in the device under test 3. The communication protocol used can be obtained by intercepting the data packets between the servo driver and the supporting test tool 41 with a packet interception tool, so as to solve the difficulty that data acquisition and control cannot be performed by simulating packet sending under the private protocol of the servo driver. The communication protocol analysis is as Figure 4 shown.

[0017] Each test project can be constructed through the following steps: as Figure 5 shown, each function of the device under test is independently encapsulated into a functional module (such as a motor enabling module, a valve control module, a driver write module, etc.). The functional module is deployed with a test process corresponding to the function. The tester selects each corresponding functional module according to the actual test requirements. The selected functional modules are freely combined to form different test units (such as no-load test unit, load test unit, limit test unit, temperature rise test unit, etc.). Different test units are automatically sorted according to the test process to form a final test project for subsequent automatic testing.

[0018] Taking the temperature rise test unit and the limit test unit as examples, the test processes corresponding to the test units are described in detail below.

[0032] S706, decrease the pressure (10), record sRegulat as pressure decrease. Return to step S703.

[0033] S707, whether the actual rotational speed can be maintained. If so, execute step S708. If not, execute step S713.

[0041] S715, halve the pressure numerical variable iRegPress. Return to step S714.

[0042] After the test starts, the user selects a test project from multiple test projects according to the test requirements. After selecting the test project, the user can further select at least one test unit to be tested in the test project, and at least one functional module to be tested in the test unit. The test tool in the host computer automatically generates the test process corresponding to the selected test project, that is, the project test process, according to the test process in the test project, and automatically executes the test based on the project test process. Specifically, the host computer generates at least one corresponding control instruction according to the generated project test process, and sends the control instruction to the conversion unit. The conversion unit receives the control instruction sent by the host computer. The control instruction may specifically include, but is not limited to, the enable control instruction of the motor, the speed control instruction of the motor, etc.

[0043] S202, send the control instruction to the device under test for the device under test to execute the control instruction.

[0044] In the embodiment of the present application, after receiving the control instruction sent by the host computer, the conversion unit sends the control instruction to the device under test. The device under test receives the control instruction sent by the conversion unit and executes the control instruction.

[0045] S203, obtain the status data of the device under test after executing the control instruction.

[0046] In the embodiment of the present application, the conversion unit obtains the status data of the device under test after executing the control instruction. Among them, the status data may specifically include, but is not limited to, the oil temperature data, pressure data, etc. in the oil circuit.

[0047] S204, send the status data to the host computer for the host computer to generate a test result according to the status data sent by the conversion unit and / or the status data sent by the device under test, and the allowable range of the corresponding status data in the project test process.

[0048] In the embodiment of the present application, the conversion unit sends the obtained status data of the device under test after executing the control instruction to the host computer. The device under test can also directly send the status data after executing the control instruction to the host computer. The host computer generates a corresponding test result according to the status data sent by the conversion unit and / or the status data sent by the device under test, and the allowable range of the corresponding status data in the project test process. If the status data is within the allowable range of the corresponding status data, the test result is that the test passes. If the status data is not within the allowable range of the corresponding status data, the test result is that the test fails.

[0049] Before judging whether the status data is within the allowable range of the corresponding status data, the received status data can also be filtered, such as median filtering. The specific process of median filtering can be as follows: Such asFigure 8 As shown in the figure, the host computer stores the received status data curve into the curve database, and can intercept a section of stable status data in the status data curve. For this section of status data, the median filtering method is used: sample N times (for example, N = 5), sort the N data in ascending order through the bubble algorithm, then judge the parity of N, and finally take the median of the N data. For example, sample the first to fifth data, sort them in ascending order, and take the data ranked third. Among them, it is very important to intercept the appropriate data segment for analysis, and the data at the start and end of the servo motor should be excluded. Therefore, the database statement "ORDER BY (graph_x+0) DESC LIMIT 1" can be used to determine the time at the end of the curve at this time, and take the data of the previous few seconds before this time.

[0050] Furthermore, the test method of the embodiment of the present application may further include: automatically generating a corresponding test report including multiple test results according to multiple test results, which is convenient for problem tracing.

[0051] The embodiment of the present application can also automatically establish a test resume based on multiple test reports. It can also automatically upload the test report to the company database system in the cloud for easy remote viewing.

[0054] The host computer 4 is communicatively connected to the fourth communication module NET of the device under test 3 through the second communication module NET2, that is, the device under test 3 sends the status data after executing the control instruction to the second communication module NET2 of the host computer 4 through the fourth communication module NET.

Figure 3 The conversion unit 5 in it may further include an emergency stop switch 54, and the emergency stop switch 54 is connected to the protocol conversion module 53 for connecting or disconnecting the connection between the protocol conversion module 53 and the host computer 4.

[0061] Correspondingly, the above step "generating an analog control signal according to the control instruction" may specifically include the following steps: converting the control instruction in the first protocol format sent by the host computer into a control instruction in the second protocol format, and the second protocol format is the protocol format supported by the analog input / output module in the conversion unit; controlling the analog input / output module to generate an analog control signal according to the control instruction in the second protocol format.

[0062] In an embodiment of the present application, the protocol conversion module converts the control instruction in the first protocol format sent by the host computer into a control instruction in the second protocol format supported by the analog input / output module, and sends it to the analog input / output module. The analog input / output module generates an analog control signal according to the received control instruction in the second protocol format.

The servo driver 31 is respectively connected to the analog input / output module 51 and the host computer 4; the amplification module 32 is connected to the analog input / output module 51.

[0065] In an embodiment of the present application, the analog input / output module sends the generated analog control signal to the corresponding module in the device under test, such as a servo driver, an amplification module, etc.

[0066] Further, the above step S204 of "sending the status data to the host computer" may specifically include the following steps: converting the status data obtained from the device under test into status data in the first protocol format; sending the status data in the first protocol format to the host computer.

[0067] In an embodiment of the present application, the conversion unit converts the status data obtained from the device under test into status data in the first protocol format through the protocol conversion module, and sends the status data in the first protocol format to the host computer.
