Third, some functions:
1. Automatically clear: the computer receives the test start command, and the measurement system automatically clears it.
2. Automatic return: After the automatic identification test breaks, the movable beam automatically returns to the initial position at high speed.
3, automatic save: test data and experimental conditions automatically save the disk, to prevent data loss caused by sudden power failure forgotten to save the disk
4, the test process: the test process and measurement, display, analysis, etc. are completed by the microcomputer
5, display mode: data and curve dynamic display with the test process
6. Reproduction of results: The test results can be arbitrarily accessed, and the data curve can be reanalyzed.
7. Curve traversal: After the test is completed, the mouse can be used to find the point-by-point force value and deformation data of the test curve, which is convenient and practical for obtaining test data of various materials.
8. Comparison of results: Multiple test characteristic curves can be superimposed, reproduced, enlarged, and presented with different colors for analysis and comparison;
9. Curve selection: You can select the stress strain, force time, intensity time and other curves to display and print according to your needs;
10. Batch test: After the test with the same parameters is set once, the test of a batch of samples can be completed in sequence;
11, test report: (according to customer needs)
Tensile: maximum force, tensile strength, elongation at break, elastic modulus, etc. Bending: compression of maximum force, bending strength, deflection, elastic modulus, etc.: maximum force, compressive strength, yield strength, elastic modulus, etc. The test report can be programmed and printed in the format required by the user;
12, limit protection: with program control and mechanical two-level protection;
13. Overload protection: automatically stop when the load exceeds 10% of the rated value;
Emergency stop: There is an emergency stop switch for emergency shutdown of the whole machine power supply;
Automatic diagnosis: The system has automatic diagnosis function, and the measurement system and the drive system are over-pressed, over-current, over-temperature, etc., and the abnormal situation is immediately stopped;
14. Implement independent operation of the host and the microcomputer;
Fourth, the reliability of the computer control test machine accuracy in the electrical part mainly in hardware and software; generally speaking, the more complex the system reliability is lower, under the conditions of guaranteed function, try to choose components with high integration and new technology. , reducing the number of components and solder joints. Our company is more than 3 times larger than other manufacturers' software code in software. However, due to the modular software structure and the structure of debugging and separating, the software of our company has already got rid of the level of laboratory-level products; specifically, the experiment The room-level product is that the main program constantly modifies its functions. Every time you debug, you need to re-modify the main program to make the main program mature. This software separates the main program from the automatic calculation program and report files. The user's request is modified; the developer concentrates on making the main program mature without adding functionality, and the debugger is only responsible for modifying the automatic calculation program and report file, and because the software is based on the MS-ACCESS database, the advantages of the database approach in the data processing side Played out, the automatic calculation program is greatly simplified, and the report file is visually produced using Crystal Reporter, which is simple and reliable.
