Description

Technical Field

[0001] The present invention relates to the technical field of testing equipment, and in particular to an automated experimental testing device for a rotary opening and closing product and a testing system thereof. Background Art

[0002] In the electrical industry, with the rapid development of technologies such as smart grids, industrial automation, and smart homes, the requirements for electrical control and switching equipment are increasing, especially for those equipment components that require frequent rotation operations to switch circuit states or adjust parameters, such as universal transfer switches, knobs, relays, contactors, as well as miniature circuit breakers, small and micro isolating switches, etc. The stability and durability of their performance are directly related to the safety and reliability of the entire electrical system.

[0003] According to national standards GB / T14048.5 and its related series (such as GB / T10963 and GB / T16917), these rotating control electrical components must undergo a series of rigorous rotating tests to verify their operating performance, durability, safety protection mechanisms, and compliance with various technical indicators specified in the standards under different operating conditions. However, traditional rotating test equipment often has the following limitations:

[0004] Single function: Many traditional devices can only perform basic rotation operation tests and lack advanced functions such as multi-parameter synchronous monitoring, fault simulation, and real-time data analysis.

[0005] Low degree of automation: The testing process requires a lot of manual intervention, which is not only inefficient but also prone to human errors, affecting the accuracy of test results.

[0006] Insufficient test accuracy: For miniature rotary control components, accurate measurement and control of parameters such as rotation angle, speed, and torque is a major challenge. Traditional equipment often finds it difficult to meet high-precision requirements.

[0007] Limited scope of application: Rotary control components of different specifications and models require different test fixtures and test procedures. Traditional equipment often lacks flexibility and scalability, making it difficult to meet diverse testing needs.

[0008] Weak data processing and analysis capabilities: The collection, organization, and analysis of test data are cumbersome, and it is difficult to quickly generate intuitive test reports, which is not conducive to subsequent quality control and product development.

Before the countdown ends, the experimenter can terminate the system operation at any time.

[0029] A testing method for a test system of an automated experimental testing device for a rotary opening and closing product comprises the following steps:

[0030] Step 1: First, adjust the distance between the upper and lower mounting plates in the fully compatible mounting plate using the mounting plate adjustment mechanism according to the specific structure of the experimental product to ensure that the spacing between the mounting plates meets the installation requirements of the experimental product;

[0031] Step 2: Place the experimental product on the adjusted fully compatible mounting plate and secure it with the fixtures on the mounting plate. After the product is installed, fine-tune the mounting plate adjustment mechanism again to ensure that the position of the experimental product is roughly consistent with the predetermined experimental position, and then lock the sample mounting platform.

[0032] Step 3: Use the front-to-back adjustment mechanism in the three-dimensional six-way adjustment mechanism to initially move the test mechanism to the appropriate position of the experimental product, and lock the front-to-back adjustment mechanism. Further fine-tune the vertical adjustment mechanism and the horizontal adjustment mechanism to fully align the center points of the experimental product and the adjustable rotary cylinder. Use the focus calibration module to ensure accurate centering of the center point. After alignment is complete, lock all adjustment mechanisms.

[0033] Step 4: After ensuring that the test mechanism and the sample are aligned, precisely connect the various parts of the three-section adjustable connecting transmission assembly, including the first sample fixing section, the second front-to-back adjustment section, and the third up-and-down adjustment section, to the handle of the experimental product. First, connect the clamp to the front end of the adjustable rotary cylinder, and then adjust the positions of the third up-and-down adjustment section and the second front-to-back adjustment section in sequence according to the sample position until the first sample fixing section can be accurately connected to the experimental product. Based on the specific conditions of the experimental product, including whether there are irrelevant human operation sections, the required driving force, and the handle angle, flexibly select the connection method and adjust the force arm position and the front-to-back position of the connecting transmission component, and finally lock all relevant connecting parts;

[0034] Step 5: According to the initial position of the experimental handle, adjust the initial position of the adjustable rotary cylinder to ensure that the starting position of the test mechanism is consistent with the starting position of the experimental product. Then, according to the angular displacement requirements of the experimental product, adjust the rotation stroke of the test mechanism to ensure that there will be no incomplete closure or over-travel during the experiment;

[0035] Step 6: Open the air valve to supply air. Supply air to the adjustable rotary cylinder through the PLC touch screen all-in-one machine and the solenoid pilot valve. Use the inlet and outlet air valve adjustment screws on the adjustable rotary cylinder to adjust the air supply flow. At the same time, the focus calibration module in the control system will monitor the displacement time between the initial and final positions and automatically calculate whether the running speed meets the standard requirements. When the speed adjustment meets the requirements, the system will automatically give a prompt. The experimenter will lock the position of the air valve adjustment screw according to the signal to complete the speed adjustment.

[0036] Step 7: After the experimenter completes all the above steps and confirms that they are correct, he / she will first perform a manual run test to check whether the experimental product is running normally and meets the standard requirements. After confirmation, various experimental data are set according to the experimental requirements, and the experimental system is started for formal experiments. During the experiment, the data acquisition module will collect experimental data in real time, and the experimental status and results can be displayed through the experiment display module.

[0037] The present invention has the following beneficial effects:

[0061] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0062] like Figure 1-5 As shown, the present invention is an automated experimental testing equipment for rotary opening and closing products, including a three-section adjustable connecting transmission component 1, a sample mounting platform 2, a support stand 3, a three-dimensional six-direction adjustment mechanism 4 and a control unit 5. The three-section adjustable connecting transmission component 1 includes a first sample fixing section 11, a second front-to-back adjustment section 12, and a third up-and-down adjustment section 13. One end of the first sample fixing section 11 is connected to the second front-to-back adjustment section 12 by a movable screw, and the other end is connected to the sample placed on the sample mounting platform 2 for applying rotational force and testing. One end of the second front-to-back adjustment section 12 is connected to the first sample fixing section 11 by a movable screw. The fixed segment 11 is connected by a movable screw, and the other end is connected to the third up and down adjustment segment 13 by a movable screw. One end of the third up and down adjustment segment 13 is connected to the second front and rear adjustment segment 12 by a movable screw, and the other end is clamped and fixed to the three-dimensional six-direction adjustment mechanism 4. The three-dimensional six-direction adjustment mechanism 4 is installed on the right side of the support frame 3 for adjusting the position of the test equipment, and the sample mounting platform 1 is installed on the left side of the support frame 3 for adjusting the installation position of the sample. The control unit 5 is installed below the support frame 3 and connected to the three-dimensional six-direction adjustment mechanism 4 for controlling the position and operation of the three-dimensional six-direction adjustment mechanism 4.

[0063] By adopting the above technical solution, the first sample fixing section 11 is used as a component directly connected to the sample to ensure that the sample is stable and can accurately transmit rotational force during the test. Its design makes sample installation convenient and quick, and is applicable to samples of various specifications; the second front and rear adjustment section 12 is connected to the first sample fixing section 11 and the third upper and lower adjustment section 13 through a movable screw, so as to achieve precise adjustment of the sample in the horizontal front and rear direction, thereby enhancing the adaptability of the equipment to different test scenarios; the third upper and lower adjustment section 13 is connected to the second front and rear adjustment section 12 and the three-dimensional six-way adjustment mechanism 4, and is responsible for the vertical adjustment of the sample in the upper and lower directions. The three-stage design makes the entire transmission assembly highly flexible in three-dimensional space, and the product connection component has a large adjustment range, which can be adjusted according to the size and position of the test product handle. With the cooperation of the upper and lower front and rear components, it can be connected to the handle of the product under test at any position, and has extremely high compatibility. Through the cooperation of these three components, the length of the torque arm of the driving experimental product can be adjusted arbitrarily to meet the size of the driving torque of the experimental product. At the same time, the connecting component can make fine adjustments to the axial distance between the driving mechanism and the experimental product in a small range. As a supplement to the axial adjustment of the large driving platform, the connection of the product is more precise. The experimental product and the product connecting component are connected through a tight fit to test products that do not have irrelevant human operation sections, and the loose margin connection can achieve compatibility with some products with irrelevant human operation sections.

[0064] The three-stage adjustable connection transmission assembly 1 also includes a clamp 14 and an adjustable rotary cylinder 15. The clamp 14 is connected to the third upper and lower adjustment section 13 to fix the position of the third upper and lower adjustment section 13. The rear end of the clamp 14 is installed on the adjustable rotary cylinder 15. The adjustable rotary cylinder 15 adjusts the positions of the clamp 14 and the first sample fixing section 11, the second front and rear adjustment section 12, and the third upper and lower adjustment section 13 at the front end to achieve the purpose of rotating the sample.

[0065] By adopting the above technical solution, the connection and fixation between the clamp 14 and the third upper and lower adjustment section 13 ensures the stability of the third upper adjustment section 13 during the test, prevents position displacement caused by external force or vibration, and ensures the accuracy and reliability of the test. The introduction of the adjustable rotary cylinder 15 enables the clamp 14 and the first sample fixing section 11, the second front and rear adjustment section 12, and the third upper and lower adjustment section 13 connected to its front end to be rotated and adjusted as a whole, which not only realizes the rotation test of the sample, but also allows the user to flexibly adjust the rotation angle and speed according to experimental requirements, greatly expanding the test function and application range of the equipment. In addition to having the function of connecting the two, the clamp 14 can also perform wide-range positioning for product handles whose initial rotation angle is not in the vertical position by adjusting the position of the fixing hole of the clamp 14 on the adjustable rotary cylinder 15, and perform fine positioning by adjusting the starting angle of the cylinder, thereby providing comprehensive compatibility for various types of products.

[0066] The sample mounting platform 2 includes a fully compatible mounting plate 21 and a mounting plate adjustment mechanism 22 . The fully compatible mounting plate 21 is mounted on the mounting plate adjustment mechanism 22 to support up and down movement.

[0067] By adopting the above technical solution, the design of the fully compatible mounting plate 21 enables it to support the installation of a variety of experimental products of different sizes, shapes, and specifications, enhancing the versatility and compatibility of the equipment, allowing the same equipment to be used for testing a variety of different types of products, reducing equipment costs and test preparation time. The mounting plate adjustment mechanism 22 allows the fully compatible mounting plate 21 to move up and down in the vertical direction. This flexible adjustment capability allows the equipment to be adjusted according to different testing requirements.

[0068] The fully compatible mounting plate 21 includes an upper mounting plate 211 and a lower mounting plate 212. The opening positions of the upper mounting plate 211 and the lower mounting plate 212 are symmetrical up and down. The upper mounting plate 211 and the lower mounting plate 212 are both mounted on the mounting plate adjustment mechanism 22.

[0069] The mounting plate adjustment mechanism 22 includes a mounting plate slider 221 and a mounting plate heavy-duty rail 222. The mounting plate heavy-duty rail 222 is vertically installed on the support stand 3. Mounting plate sliders 221 are installed at both ends of the upper mounting plate 211 and the lower mounting plate 212. The upper mounting plate 211 and the lower mounting plate 212 are mounted on the mounting plate heavy-duty rail 222 through the mounting plate slider 221 and move up and down for adjustment.

[0070] By adopting the above technical solution, it is compatible with the installation of products of various models, specifications and structures that currently need to conduct such experiments. The mounting plate has two adjustable mounting hole types, which are compatible with the installation specifications of all types of rotary buttons currently. It has two sets of adjustable mounting guide grooves, which are compatible with all current product requirements for installation through external bolts. For specific products that need to be installed in a box for testing, this type of guide groove can also be fully compatible with the box.

[0071] The three-dimensional six-way adjustment mechanism 4 includes a front-to-back adjustment mechanism 41, an up-and-down adjustment mechanism 42 and a left-to-right adjustment mechanism 43. The adjustable rotary cylinder 15 is installed on the left-to-right adjustment mechanism 43 to adjust the left-to-right position of the first dimension. The left-to-right adjustment mechanism 43 is installed on the up-and-down adjustment mechanism 42 to adjust the up-and-down position of the second dimension. The up-and-down adjustment mechanism 42 is installed on the front-to-back adjustment mechanism 41 to adjust the front-to-back position of the third dimension.

[0072] Adjustment sliders 44 are installed on the back of the front and rear adjustment mechanism 41, the up and down adjustment mechanism 42 and the left and right adjustment mechanism 43. The surfaces of the up and down adjustment mechanism 42, the front and rear adjustment mechanism 41 and the support platform 3 are provided with adjustment heavy-duty rails 45. The adjustment slider 44 on the back of the front and rear adjustment mechanism 41 is connected and slid with the adjustment heavy-duty rails 45 on the surface of the support platform 3. The adjustment slider 44 on the back of the up and down adjustment mechanism 42 is connected and slid with the adjustment heavy-duty rails 45 on the surface of the front and rear adjustment mechanism 41. The adjustment slider 44 on the back of the left and right adjustment mechanism 43 is connected and slid with the adjustment heavy-duty rails 45 on the surface of the up and down adjustment mechanism 42.

[0073] By adopting the above-mentioned technical solution, the three-dimensional six-way adjustment mechanism 4 can achieve precise position adjustment in the three dimensions of front and back, up and down, and left and right. By adjusting the sliding of the slider 44 on the heavy-duty rail 45, the smoothness and precision of the adjustment process are ensured. The multi-dimensional adjustment capability greatly improves the adaptability of the experimental equipment to experimental products of different shapes, sizes and characteristics. After the adjustment is completed, each adjustment mechanism can strongly lock the slider to ensure that no displacement occurs during the experiment. The locking mechanism ensures the accuracy and reliability of the test and avoids test errors caused by position changes. The front and rear adjustment mechanism 41 uses heavy thickened steel plates as the bearing platform, which is tightly connected to the drive platform gantry frame. It not only provides strong support force, but also ensures the stability of the entire adjustment mechanism during the adjustment process. Through the design of a reasonable adjustment range and heavy structure, the three-dimensional six-way adjustment mechanism 4 can achieve large-scale adjustment of the experimental product in various dimensions.

[0074] The control unit 5 includes an electrical control box 51, a PLC touch screen all-in-one machine 52, a signal indicator 53 and an electromagnetic pilot valve 54. The electrical control box 51 and the PLC touch screen all-in-one machine 52 are installed on the side of the support stand 3, the signal indicator 53 is installed on the top of the electrical control box 51, and the electromagnetic pilot valve 54 is installed under the support stand 3 and is respectively connected to the electrical control box 51 and the adjustable rotary cylinder 15, and the PLC touch screen all-in-one machine 52 is connected to the electrical control box 51.

[0075] By adopting the above technical solution, the electrical control box 51 is used to install the electrical control components of this set of special experimental equipment, including various drive relays, DC power supply, input and output interfaces, etc. The PLC touch screen all-in-one machine 52, as the core control component, works closely with the electrical control box 51 to achieve precise control of actuators such as the adjustable rotary cylinder 15. By pre-setting programs or adjusting parameters in real time, the rotation angle, speed, etc. of the cylinder can be precisely controlled to ensure the accuracy and repeatability of the experimental process. The signal indicator 53 is installed on the top of the electrical control box 51 and can intuitively display the operating status and fault information of the equipment. Once an abnormal situation occurs in the equipment, the signal indicator will immediately sound an alarm to remind the user to take timely measures to prevent the accident from expanding. The electromagnetic pilot valve 54, as a key component of the control air circuit, is closely connected to the electrical control box 51 and the adjustable rotary cylinder 15. Through the control signal sent by the electrical control box 51, the electromagnetic pilot valve can accurately control the on-off and flow of the air circuit, thereby achieving precise control of the cylinder.

[0076] A test system for automated experimental testing equipment for rotary opening and closing products, comprising:

[0077] Focus calibration module A, such as Figure 7 , by connecting an external laser and a focus receiver for center focus calibration of the center position of the adjustable rotary cylinder 15, and by connecting a high-precision photoelectric switch for measuring whether the speed of the adjustable rotary cylinder 15 meets the experimental threshold;

[0078] Experimental demonstration module B, such as Figure 9 , used to select experimental projects and display the data content and status of partition modules.

[0079] Experimental Demonstration Module B includes:

[0080] Parameter input module C is used to set all experimental control parameters for dual current experiments, such as Figure 10 Time from ten times the current test closing to sample closing (time from ten times the current test closing to sample closing); time from sample closing to ten times the current test closing (time from ten times the current test closing to one times the current test closing); time from one close to sample closing (time from one times the current test closing to sample disconnection); time from sample disconnection to one minute (time from sample disconnection to one times the current test closing); experimental interval time. The three experimental processes of sample closing to ten times the current test closing, ten times the current test closing to one close, and one close to sample closing are the key stages of the entire experiment. In order to ensure the time accuracy requirements of some special experiments, the time of these three places can be measured by the following methods: Figure 11 The time base switch button switches between 100 milliseconds and 10 milliseconds to improve the experimental control accuracy. The status indication of each experimental control unit in the experiment is shown as follows: Figure 12 The three indicator lights indicate the real-time status of each experimental control unit during the experiment. The number of experiments is as follows: Figure 13 The number of experiments is input into the input box, which determines the number of experiments. This parameter is input into module C. There is an implicit check function in the program control. If the experimental parameters exceed the maximum allowable value due to the experimenter's mistake, the system cannot be started and the experimenter will be prompted to review the parameters.

[0081] Data acquisition module D, such as Figure 14 , used to collect real-time data of various experiments during the experiment. There are two analog data acquisition channels and two digital data acquisition channels. The analog data acquisition channel can select current and voltage signals according to the different transmitters used by the experimenters. The digital acquisition channel can be freely selected according to whether the auxiliary contacts of the relevant experimental products are normally open or normally closed. Therefore, the selection of these four channels has great flexibility. The four channels can be selected at the same time or only one or several channels can be selected for use. The collected data will be provided to the sample monitoring and system protection units in the protection area as a basis for judgment;

[0082] Protection selection module E, such as Figure 15 , which is an area that provides monitoring and protection for the experimental status of experimental products and the operational safety of the experimental system during the experiment. In the dual-current experiment, an external control unit is required as a companion test. The data collected by analog quantity cannot be used as the basis for sample monitoring. Therefore, in this system, digital quantity monitoring is adopted for sample monitoring of dual-current experiments. The relationship between the change of digital quantity and time is used to judge whether the experimental sample is damaged. The system protection is selected as the highest protection level of this special experimental system. Therefore, both analog and digital data will be read and analyzed. If the system finds that the data of any channel in all channels meets the protection requirements and meets the protection time setting, it will immediately start the protection function and cut off the experimental power supply. At the same time, the system can be seamlessly connected with the highest level protection system of the laboratory. When necessary, it can start the large system protection and directly cut off the main power supply of the experimental line to protect the safety of the experimental system.

[0083] Experimental control module F, such as Figure 16, used for comprehensive control of the experiment, including local start and stop, remote start and stop, experiment confirmation, time base selection, clear / reset, sample normally open and normally closed selection. Local start and stop is activated when the remote / local selection switch is in the local state. The button can be used to control the permission of the experimental system on site. It is mainly used for system debugging and sample simulation testing; remote start and stop is used to switch the start and stop position selection of the experimental system. During normal experiments, the button is placed in the remote position, and the experimental system is started and stopped by remote control to ensure the safety of the experimental personnel; the experiment confirmation button is used for the experimental personnel to confirm whether the experimental parameters, experimental product installation, etc. are completed. After confirming that all experimental preparations are completed, the experiment personnel press this button to the confirmation state, and the experimental control system can enter the ready-to-run state. If the experiment confirmation button is not in the confirmation state, the experimental system cannot be started. At the same time, if an abnormality is found during the experiment, press this button and the system It can stop immediately, so this button also has the implicit emergency stop function; the time base selection button is used to switch the time calculation unit of the main sequence experiment stage and the monitoring and protection time in the experimental system. It can be switched between 10 milliseconds and 100 milliseconds in the parameter input module C to improve the accuracy of experimental control and protection; the clear / reset button is used to clear and reset the protection or alarm situation during the experiment. Only after the experimenter has dealt with the relevant abnormal situation, he can press this button to clear the fault lock and alarm and reset the system to the initial state. The experimenter can restart the experiment after resetting the parameters according to the experimental process. The sample normally open and normally closed selection button is used to select the experimental product structure state. If the experimental product contact is a normally closed structure, the experimenter needs to select this button as normally closed to conduct the experiment. If the experimental product contact is a normally open structure, the experimenter needs to select this button as normally open to conduct the experiment;

[0084] Status indication module G, such as Figure 17 , used to indicate the real-time status of the system operation, to remind the experimenters to pay attention to the system operation status;

[0085] Run the timing module H, such as Figure 18 , which is the countdown between the start of the experimental system and the formal conduct of the experiment, so that the experimenter can reserve the final review time before the formal conduct of the experiment. Before the countdown ends, the experimenter can terminate the system operation at any time.

[0086] A testing method for a test system of an automated experimental testing device for a rotary opening and closing product comprises the following steps:

[0087] Step 1: First, according to the specific structure of the experimental product, adjust the distance between the upper mounting plate 211 and the lower mounting plate 212 in the fully compatible mounting plate 21 through the mounting plate adjustment mechanism 22 to ensure that the spacing between the mounting plates meets the installation requirements of the experimental product;

[0088] Step 2: Place the experimental product on the adjusted fully compatible mounting plate 21 and secure it with the fixture on the mounting plate. After the product is installed, fine-tune the mounting plate adjustment mechanism 22 again to ensure that the position of the experimental product is roughly consistent with the predetermined experimental position, and then lock the sample mounting platform 2.

[0089] Step 3: Use the front-to-back adjustment mechanism 41 of the three-dimensional six-directional adjustment mechanism 4 to initially move the test mechanism to the appropriate position of the test product, and lock the front-to-back adjustment mechanism 41. Further fine-tune the test mechanism using the up-down adjustment mechanism 42 and the left-to-right adjustment mechanism 43 to fully align the center points of the test product and the adjustable rotary cylinder 15. Use the focus calibration module A to ensure accurate centering of the center points. After alignment is complete, lock all adjustment mechanisms.

[0090] Step 4: After ensuring that the test mechanism and the sample are aligned, the various parts of the three-section adjustable connecting transmission assembly 1, including the first sample fixing section 11, the second front-to-back adjustment section 12, and the third up-and-down adjustment section 13, are precisely connected to the handle of the experimental product. First, the clamp 14 is connected to the front end of the adjustable rotary cylinder 15. Then, the positions of the third up-and-down adjustment section 13 and the second front-to-back adjustment section 12 are adjusted in sequence according to the position of the sample until the first sample fixing section 11 can be accurately connected to the experimental product. According to the specific conditions of the experimental product, including whether there are irrelevant human operation sections, the required driving force, and the handle angle, the connection method is flexibly selected and the force arm position and the front-to-back position of the connecting transmission component are adjusted. Finally, all relevant connecting parts are locked.

[0091] Step 5: According to the initial position of the experimental handle, adjust the initial position of the adjustable rotary cylinder 15 to ensure that the starting position of the test mechanism is consistent with the starting position of the experimental product. Then, according to the angular displacement requirements of the experimental product, adjust the rotation stroke of the test mechanism to ensure that there will be no unclosed or over-stroke during the experiment;

[0092] Step 6: Open the air valve to supply air, supply air to the adjustable rotary cylinder 15 through the PLC touch screen all-in-one machine 52 and the electromagnetic pilot valve 54, adjust the air flow rate by adjusting the inlet and outlet valves on the adjustable rotary cylinder 15, start the laser assembly, and at the same time Figure 7After the button under the laser position focus in the interface is in the start state, adjust the position of the adjustable rotary cylinder 15 until the laser focus receiver at the center point of sample rotation receives the laser signal. After the laser position focus signal light is on, lock the position of the relevant mechanism after the center focus work is completed, connect the drive mechanism and the experimental product, and then perform the experimental speed calibration. Place a high-precision photoelectric switch at the start and end positions of the experiment, enter the standard value at the speed standard requirement value, and then click Start. At the same time, drive the system by controlling the pilot solenoid valve 54, and adjust the inlet and outlet air volume by controlling the air valve screw. The system's built-in program will automatically calculate the speed according to the feedback signal from the photoelectric switch. When the speed adjustment meets the input value, the system in place indicator light will light, the speed adjustment is completed, lock the control air valve screw, and then press the return button to the previous level, and the system will return to the welcome interface.

[0093] Step 7: After the experimenter completes all the above steps and confirms that they are correct, Figure 6 After pressing the Welcome button on the Welcome screen, Figure 8 Select the experimental project on the experiment selection interface. The system enters the display interface of the experiment display module B. Select the experimental parameter time in the parameter input module C. Enter 5 (500ms) for the interval from ten to sample, 2 (200ms) for the interval from sample to ten, 1 (100ms) for ten to one, 2 (200ms) for one to sample minute, and 5 (500ms) for sample minute to one minute. Enter 100 (10s) for the experimental interval. Switch to the time base to be used. This experiment uses 100ms. Enter 5000 in the experiment number interface (the number of experiments specified in the third program segment standard).

[0094] Enter the data acquisition module D settings. In this experiment, we use analog channel 1 as the system voltage acquisition and monitoring, analog channel 2 as the experimental current acquisition and monitoring, and digital channel 1 is connected to the normally closed contact of the experimental sample for monitoring. Input an input value of no more than 250 for analog channel 1, and enter 100 here (voltage monitoring 100V). Input an input value of no more than 20A for analog channel 2, and enter 2A here (current monitoring 2A). Set digital channel 1 as a normally closed button. After setting, set the input and exit buttons of these three channels to input. At this time, data acquisition of all three channels is fully activated.

[0095] Enter the protection selection module E setting, the sample monitoring input is 110 (11 seconds), and the sample monitoring button is selected to be put into use, then the sample monitoring is automatically put into use. The system automatically monitors the selection of the digital channel and does not need to be manually set again. The system protection time is set to 6 (600 milliseconds);

[0096] After confirming that all parameters have been set, ensuring that the operating conditions of the experimental equipment are sufficient and error-free, select the experiment confirmation button in the experiment control module F, and a 10-second countdown will appear in the operation timing module H between the start of the experimental system and the formal experiment, so that the experimenter has a final review process before the formal experiment. Then start the experiment. During the experiment, the status indication module G is used to indicate the real-time status of the system operation to remind the experimenter to pay attention.
