Design And Implementation Of Falling Weight Impact Tester Control System

Falling weight impact tester as the determination of all kinds of plastic pipe impact resistance toughness necessary test equipment, widely used in determination of resistance to impact toughness of various kinds of plastic tubing. Falling weight impact tester for plastic pipe material impact operating automation level is not high, test process is given priority to with manual operation, by artificial way of the authors of the completed test data record, test report, test conclusion determine not only low efficiency, but also for mistakes, such as cheating is difficult to avoid, to a large extent influence the accuracy of the plastic pipe material impact test results.This paper is aiming at these problems, using computer software, automation control, database and other technical design has realized the drop hammer impact testing machine control system, the key to solve the lack of Falling weight impact tester data processing capacity and low efficiency of manual test.This paper on falling weight impact tester control system development present situation at home and abroad has carried on the simple introduction, then the falling weight impact tester control system design has carried on the demand analysis, from two aspects of functional and nonfunctional requirements are expounded, and then analyzes the realization of system solutions, compared the main technology available, determine the concrete scheme of implementation system, choose the main technical, then to illustrate the general design scheme of the system, the system design including PC and the function module design, the system communication protocol design, database design, etc., the one by one, finally from the two aspects of PC and lower machine introduces the method to realize the system function, system login, experiments of PC information recorded, test status, test results determine parts, such as lower machine equipment type selection, the design of the power supply and the main program, display, receiving data, such as part of the design and realization method are introduced.Tested and run for a period of time, proof design of falling weight impact tester control system is better done in the process of impact test machine control, data management, result determination, and other functions, has good stability and reliability, improve the efficiency of the impact test, reached the predetermined target.
