Study Of The Impact Of Body Movement Signal Acquisition Technology

Moving object that will cause high-speed compacting intermittently exists in many experimental equipment, at the same time, transient parameters in impacting process needed measuring. In this paper, basing on the drop hammer device, a suit of storage test system fixed on the moving object is designed. Transient parameters in the impacting process are storaged and then transmitted to computer by wireless method, and parameters of data acquisition can be set by computer. The main content includes: applying complex programmable logic device to acquire and memorize data high speedily, useful data range of the multiplex transient parameters is caught and transmitted to computer so they can be displayed, analyzed and saved.
