4. Description of main functions of software
The measurement and control software is used for microcomputer control electronic universal testing machine for all kinds of metal and nonmetal (such as, man-made board, etc.) test, in accordance with the corresponding standards to complete real-time measurement and display, real-time control, and a variety of functions such as data processing and result output.
(1) the rights management, the operators of different levels have different operating authority, actionable menu, etc are also different, even ordinary operator operation is simple, convenient, fast, and effective protection system;
(2) real-time measurement and display test force and peak, displacement, deformation and other signals;The real-time acquisition and control of NT mode platform of Win2000 and WinXP are realized.Accurate timing and high-speed sampling are realized.
(3) the real-time display of various test curves such as load-deformation, load-displacement and other test curves can be switched on at any time, and the amplification and reduction of the curve are very convenient;
(4) parameters of computer storage, set, load, and zero and calibration operations from the software, the parameters can be convenient for storage and transfer into, so that a host with multiple sensors can easily switch, and there is no limit to the number of;
(5) support uniform velocity displacement control mode;The standard reference curve is given in the process of debugging parameters of senior operators, so that the effect of each parameter on the effect can be observed.
(6) analyze data by man-machine interaction.Processing methods widely used meet the GB/T 228-2010 metal material room temperature tensile test method "requirement, can be automatically calculated elastic modulus, yield strength, extension strength and other performance parameters, can also be artificial intervention analysis process, improve the accuracy of analysis;Other data processing can be performed according to the standard provided by the user.
(7) test data to a text file storage, to facilitate the user query, and the use of any general commercial reports, word processing software then made on the test data processing, convenient transfer data network at the same time;
(8) the data curve can be recorded and saved in the whole process, and it has the demonstration function to realize the test curve.It can also be compared with the curve superposition, which makes it easier to compare and analyze.
(9) the test report can be printed according to the user's requirement format.The user can select the report and output basic information and test results and the content of the test curve to meet all the needs.
(10) realize the digital zero and automatic calibration of the test force and deformation, which facilitates the operation and improves the reliability of the machine.Various parameter system Settings are stored in the file format for easy preservation and recovery.
(11) can be used in Win98, Win2000, WinXP and other operating systems.The control of test process, change of beam movement speed, parameter input and other operation can be completed with keyboard and mouse.
(12) it can automatically identify and support external point movement control, so that it is convenient to install the sample.
(13) it has overload protection automatic stop function, and can automatically judge the sample fracture and automatic stop.Depending on the user's requirements, the above software functions will be added or changed.
