| The safe standard of the automobile is divided into the active safety standard, general safe standard and passive and safe standard. The active safe standard mean the pilot adopts according to the road circumstance the measure avoids to let the insurance feeling, active prevention trouble in involve of the vehicle technique request; General safety the standard is the technique request to the vehicle structure, main technique parameter, the sketch signal etc; The passive safety standard avoids or reduces in the trouble to the harmful technique request of the car wife member.The headrest of a chair of automobile is an important device that protects passenger's neck and heads, belonging to the passive and safe function realm, need to be according to the GB11550- a chair of 1995《automobile headrest function requests and experiments the method》of request carries on the examination, if not agree with the up to standard request, can't pack the car usage. Because relating to the passenger's life safety to the examination of the headrest directly, so need a set of accuracy high, the test system that credibility like to evaluate the function of a chair of automobile.Along with the technical development of virtual instrument, adopt the low cost software to turn the technique, research to manufacture each kind of multi-function intelligence test equipment to present fast fierce develop its power, and the gradual batch quantity enters the industry test realm. Especially in the professions, such as machine, metallurgy and test...etc., have already melted into the virtual instrument of various type in great quantities, its outstanding function, stronger function expands sex, transplantation, good data on-line processing ability and the data communication ability of solid hours and person's machine of the amities to hand over with each other terrace, get each profession researcher's widespread concern.This text combined the virtual instrument technique to develop a chair of automobile headrest examination conjecture test system. The point discusses a chair of automobile headrest examination system to constitute, soft hardware of the development, the control system of the pedestal design. Detailed studied the data to collect the selection, the signal interference of the card to repress, the language of C is in software develop of application. The test system that studies the development obtained the good result in the application.Should test the system to mainly have the following characteristics:①The whole test process of completes automatically under PC machine and the control of the softwares, automation and intelligences that carried out the test process turn;②Can actually the hour collect various experiment the data and output with the curve or the data form;③The ability logarithms according to carry on the backup with print;Have the auto reports to the police to experiment the function of the system with automatic close, that the system circulates the safe credibility with the assurance;④The test system interface amity, be easy to the operation, the system function can expand sex good, test the accuracy is high, the stability compare good, the cost is low, simple easy to maintenance etc. characteristics.Pass the actual test to experiment, proved that system complete satisfy the request of the test. |
