Development of Bridged Crane Dynamic Strain Test System

This system is the main part of bridged crane diagnonsis system. It can collect 8 channel signals from resistance strain bridge， and transmit the collected data to a main computer for successional software identification. This system takes advantage of singlechip MC 8098 software and hardware functions so as to make circuit structure simple and theratio of property to price raisesmuch more. The realization of parallel communication for using printer adapter port of PC in this system not only significantly increases the speed of data transmission， but also portable PC computer is used possibly. This system， therefore， has very outstanding characters of downsizing， intelligence， and timesaving.
