4、 Basic system configuration
5、 Software Introduction
The controller of the LGX testing machine consists of a main control board, a keyboard, and a display driver board, as shown in the following figure. The main control board collects force and displacement signals, drives the motor to move according to the test procedures, and obtains the required results. The main control board adopts an ARM series 32-bit processor, which is powerful and fast in operation. The following will explain the specific signal wiring, and the main control board is connected to both the keyboard and the display driver board to receive keyboard commands and output display information. The keyboard can be a key keyboard or a thin film keyboard. The LCD display can display test curves and multiple test results in real time, and can be connected to various models of needle printers or thermal micro printers to print test curves and results. There are many types of driving motors, such as DC speed controllers, stepper motors, servo motors, frequency converters, proportional valves, etc. It can be used in both harsh environments in factory production workshops and clean environments in laboratories, with fast and flexible operation.
The front of the measuring and control instrument can be divided into two parts:LCD display section, keyboard.The graph is as follows:
5.1Introduction to the functions of each part of the face key:
LCD screen: displayForce value, peak value, displacement, velocity, promptWait.
Keyboard: Used in conjunction with LCD to control operations and changes in various parameter values, as well as to control the operation of motors.
5.2Introduction to each button:
Name and Function:
[↑], [↓]The two keys, [←], are used in conjunction with [Calibration] and [Settings] to select and modify data. Below are examples interspersed in the introduction of the functions of other keys.
[Settings]Press the [Settings] key to display
This is also the state that enters directly after booting up. The first line is highlighted in reverse, indicating that the default is the first line. Press the [↑] and [↓] keys to switch between the three options. After selecting one option, press the [Settings] key to display it
The last two lines are operation prompts, with the first line highlighted in white, indicating that the default is the first line. Press the [↑] and [↓] keys to switch between multiple options, all of which are the parameters required for the previous selection. Different selections in the previous step result in different contents and numbers of options on this screen. Select an option with the [↑] and [↓] keys, and the option will be highlighted in white. Press the [Settings] key, and the last digit of the option content will flash, indicating that it can be modified. Press the [↑] and [↓] keys, and the digit will change between 0-9. Press the [←] key, and the digit will flash forward one digit. After modifying the content of the option, press the [Settings] key, and the number will stop flashing. The entire parameter item will continue to be highlighted in white. Press the [↑] and [↓] keys to select other parameter items. After all the parameters have been modified, press the [Reset] button to save all the previous modifications and enter the normal test state.
Parameter setting instructionsSet a total of 10 or more parameters (depending on the function). During a regular tensile test, apply force at a certain speed until the specimen is damaged. Before conducting the test, set the test parameters and automatically stop the pulling or crushing process. Record the maximum force, maximum strength, maximum deformation rate, and calculate the yield strength automatically.
The set parameters are:
1. Test speed: When the test button is pressed, the crossbeam moves at this speed to apply force
2. Return speed: After breaking or crushing the sample, the crossbeam returns at this speed. 0 indicates that the crossbeam does not return when the sample ruptures
3. Reduce the displacement by mm before returning, and adjust the number of times to make the position accurate when returning.
4. Force assisted movement direction 0- downward, 1- upward
5. Force units, 0->N, 1-kN, 2->kg
6. Whether to use an extensometer, 0 means not needed
7. Number, with each experiment, the number automatically increases. If a certain experiment is redone, the number can be modified, so that future experiments will start from that number. The default value for startup is 0. If set to other values, the previously saved test results can be queried.
8. Sample area, used for calculating maximum strength, maximum force divided by area equals maximum strength
9. The length of the specimen is used to calculate the deformation rate. The maximum deformation at fracture divided by the length equals the deformation rate
10. Pre tightening force, taking the tension spring wire as an example, the sample is generally not straight. If the pre tightening force is set to 50N, it means that the sample becomes straight when the force is 50N. From then on, it is used as the starting point for calculating deformation, usually set to 0
11. The initial force for breaking the shape is determined, and the breaking judgment is only carried out when it is greater than this force
12. The sample is considered to have broken when the force drops to 70% of the maximum value, with a default value of 70.
13. Whether to return, 0 indicates that the crossbeam does not return when the sample ruptures, and 1 indicates that the crossbeam automatically returns at a return speed when the sample ruptures
14. If the number of groups is less than 2, it indicates no grouping; if it is greater than 2, it indicates grouping. For example, if set to 3, after conducting 3 experiments, there will be a prompt indicating that the number of groups has been reached. At this time, if you press the query key to query the results, you can see the results of each experiment and the average of the three experiment results. Maximum 500
15. X-axis coordinate, maximum deformation. Properly setting this number can make the test curve on the LCD screen look beautiful. Generally, from the beginning of the experiment to the failure of the specimen, the amount of deformation should be filled in here. Even if the filling is not appropriate, it has no effect on the test results, only the curve display is aesthetically pleasing.
16. The Y-axis coordinate (N) of the curve can be set appropriately to make the test curve on the LCD screen look beautiful. Generally, it can be set slightly higher than the maximum test force here. Even if the filling is not appropriate, it has no impact on the test results.
17. Year, used for printing, if 0, do not print date
18. Month, used for printing, if 0, do not print date
19. When printing, if it is 0, do not print the date
After the specimen is damaged, the test results are automatically obtained, which include:
Maximum force value, tensile strength, breakpoint deformation rate
