Second, the main functional characteristics of the tensile testing machine software tensile testing machine
1 hardware
The main controller adopts the most advanced 32-bit ARM processor in 2 1 century, and its processing speed reaches the level of Pentium-class general-purpose computer. Compared with the traditional 8-bit single chip microcomputer measurement and control system, the overall performance is greatly improved, the operation speed is faster and the control accuracy is higher.
The core device of data acquisition adopts the latest ultra-high precision 24-bit AD in the United States, and the sampling rate can reach 2000 times per second, which can capture the instantaneous change process of force and the whole process resolution can reach 500,000 grids. The original 6-point calibration technology is adopted to further improve the accuracy, and the force measurement accuracy is better than the national 0.5 (highest) standard.
The displacement encoder adopts quadruple frequency technology, and the displacement resolution is improved by 4 times, and the highest is 0.0005 mm
Pulse and voltage output control mode can control any servo motor, variable frequency motor or DC motor through pulse or voltage control interface to realize smooth stepless speed regulation. In addition, the output of switch signals such as up, down and stop can be used to directly drive external relays or electromagnetic valves, and can be used to control DC motors or pneumatic and hydraulic power devices.
Advanced three closed-loop technology of speed, displacement and force can realize accurate arbitrary waveform control.
Rich interface expandability: up to 4 channels of 24-bit analog input, 3 channels of 16-bit analog output, 3 channels of pulse output, 3 channels of AB-phase photoelectric encoder input, 9 channels of switch input, 8 channels of switch output, 1 USB interface, 1 RS232 interface, 1 RS485 interface, 4 types.
All input and output interfaces adopt high-speed photoelectric isolation technology, which has strong anti-interference ability.
2. Software
Windows standard style, clear operation mode, detailed help documents and tips make it the easiest software to use in the testing machine industry at present, and your debugging and software training efficiency will be significantly improved.
Using multi-thread parallel processing technology, the curves of force-displacement, force-time, displacement-time and stress-strain can be displayed in real time during the test, and you can switch to the desired curve screen at will to check the user settings.
Standardized test process control and report output template can define any number of test standards for users to call, covering almost all test standards such as GB, ASTM, DIN, JIS and BS. Flexible and powerful self-defined test method, with constant speed, positioning displacement, constant force, constant force rate, constant stress, constant stress rate, constant strain rate and other control modes. , which can realize complex multi-step nested loop control, and can set up functions such as automatic return, automatic fracture judgment and automatic zero return.
Powerful auxiliary tools for data analysis, statistics and graph analysis, with the functions of zooming in, zooming out, translating, crosshairs, clicking and so on. Multiple historical test data can be converted into graphics and displayed simultaneously for comparative analysis. Up to 7 kinds of interval settings, 30 kinds of manual point picking and 60 kinds of automatic point picking functions. There are many statistical functions, such as maximum, minimum, average, high and low average, median, standard deviation, population standard deviation, CPK value and so on.
A completely open method of editing test results allows users to get any desired test results. More than 400 calculation results, such as maximum force, breaking force, peeling force, tensile strength, shear strength, tear strength, maximum deformation, yield force, elongation, elastic modulus, ring stiffness, non-proportional elongation, interval minimum force, interval average force, constant elongation force and constant elongation force, are automatically calculated by computer for users to choose and call.
The innovative Microsoft Word report format is simple and easy to use. As long as you can use Word, you can edit the beautiful report you want.
The authority management system enables you to lock any functional module of the software, and divide the software operation into multiple authority levels, so that unauthorized operators cannot touch unauthorized modules, and the software runs more safely and reliably.
All-digital calibration system, the calibration process is simple and efficient, and the calibration data is protected by upper and lower computers.
The powerful unit system can adapt to any unit system in the world, such as gf, kgf, N, kN, tf, lbf, ozf, tf(SI), tf(long), tf(short) and so on, and can be extended to any number of units.
More important protection mechanism: the setting of power, travel and displacement out-of-range protection, and the setting of hardware protection for upper and lower limit travel switches.
Test data management is simple, intuitive and efficient: a single test data is stored in the form of Windows standard documents, and the storage path and file name can be set freely. It avoids the shortcomings that the database file will become larger and larger and the running speed will become slower and slower when the traditional measurement and control software stores the test data in database format. As long as your hard disk is large enough, the test data can be saved indefinitely.
All operations have shortcut keys, and the manual control box can be externally connected. All common buttons such as fast forward, fast down, middle up, middle down, slow up, slow down, zero, return, test, pause and end can be externally connected.
Multi-language one-button switching: Simplified Chinese, Traditional Chinese, English and ten languages will be launched soon, including Japanese, Korean, Russian, German, French, Spanish and Portuguese.
Portable application, without installation, can be directly copied to the computer for use (serial port driver needs to be installed first), making it easier to maintain and upgrade.
