Of Vintage Hydraulic Machine Automation Acquisition And Processing System Realization

The old hydraulic universal material testing machine calculated by hand and manual judgment to issue the test report.The disadvantages of this testing method are low precision, loading rate below standard, out control of test process, great human factors, and easily to misjudgment and fairness of an unsatisfactory etc.This article is coming under this kind of Background.Firstly,through the detailed study on the working principle and oil-way structure of the old hydraulic and omnipotent material testing machine.Transformation of its hardware, solving the above-mentioned shortcomings of the machine,meeting the requirements of modern testing. Then according to the testing organization's workflow, aspect of implementation, test specification and use of compiling detection system , Automatic entrust, charges, collect samples, test, data processing flow,, for the received signal to automatically calculate, and automatically determine the test results and issue the test report.This not only mining and develop the potential of old hydraulic testing machine,but also put the entire testing process from sample collection to issue the results are incorporated into the same test system, so that the whole flow is automatic controlled by computer, greatly accelerated the detection Speed, shorten the period of test results, saving a lot of staff and implementation costs. The main points are as follows:1,Making a change for W-100 and W-600B,add pressure sensor, displacement sensor, electric valves and converter for W-100 and W-600B,and discussing detailed of the new hardware installation and how to achieve automatic control.2,Detailedly to analyze the whole process of test work and the defect of the original manual shift ,to posting the issue which need to solve. According to the part of actual work to design the correspondence model.3,Edit the software.4,Combine operation of equipment and software system, and do much comparison work.Through the above transformation not only achieve the three sets of universal testing machine equipment from data collection, transmission, analysis and calculation ,and automatic print result.But also realize the whole testing process combined to one operating system,especially unifies financial processing and the testing , has solved a big difficult problem which the finance difficulty in controls.The transformed equipment meets the requirements of all parties concerned, from precision and test speed. And the transformation is simple, it can save significantly manpower on data calculation, results judgment and report issue. The prospects will be incredible if we promote it over the country.
