Abstract
PURPOSE: To improve the precision and reliability of a monitor by automatically giving an alarm and exercising external control when a gal speed or seismic scale calculated from a two-way shock on a horizontal plane exceeds a set value while displaying and recording the arithmetic result.
CONSTITUTION: According to a fixed program, micro computer 12 analyzes the values of signals X and Y input alternately at fixed intervals to calculate a gal speed or seismic scale indicating an actual shock and sends a signal showing the arithmetic result to display unit 18 via interface 16 for digital display. Further, the computer sends the signal to printer 20 and magnetic recorder 23 via interfaces 19 and 21 together with a signal showing the current time, thereby recording the obtained data. When the arithmetic result exceeds an alarm level set by digital switch 28 via interface 27, computer 12 puts alarm contact 26 into operation via interface 24. Consequently, the precision and reliability of the monitor improve.
