Study And Develop On The Data Acquisition And Netting System Of Dynamometers For Motorcycle Engine

Engine test-bed experiment is the main means of testing the performance ofengines. Its level of automation and control precision affects the tested data's collectionand anaiysis directly. To insure control precision in the manufacture and scientificresearch, and to improve the level of automation, it is necessary to acquisit testing dataand distribute these data to Intranet.On the base of the developing condition about the engine test-bed experirnent, wedevelop the new type of computer measurement and control system based on virtualinstrument techniques. The system, which is a computer-based acquisition and nettingsystem, provides a new, fiexibility and high efficiency means for the structure design,principle research and performance test.This thesis discusses the design and implementation of the computer measurementand aquisition system for engine test-bed experiment. Aiming at the important problemsin the experiment,it analyses the structure,working principle and the performance ofthe system in particular, and discusses the development at the software design. At thesame time, it also discusses the data dealing measure. Based on the general andflexibility of the system, it has the function of adjusting the engine's speedautomatically and completing the process of the data acquisition and analysis. So thework of noting the data and drawing the graph is made simple. And it can save time andmanpower, increase the productivity and improve the working condition.The practical application proves that the new type of computer acquisition andnetting system for engine test-bed experiment possesses strong flexibility andexpandability.
