Abstract:

 By taking advantage of the timing function of single-chip microcomputer AT89C51,the proper application of external interruption to design timing,the use of the digital pipes driven by serial shift registerSN74HC164N to display time,and the design of the circuit board according to the circuit principle drawing,the automatic timing device which can be applied to the long-term property test of fiberglass reinfoced plastics(FRP) pipes has been made, which solves the difficult problem of long time data collection in the long-term property test of FRP pipes.

Key words: FRP pipe, long-term property, single-chip microcomputer
