Title:
DIGITAL OSCILLATION CONTROLLER
Document Type and Number:
Japanese Patent JPS59140522
Kind Code:
A
Abstract:
PURPOSE:To shorten the time required for programming, by constituting an oscillation controller in the digital system with a microprocessor as the central component to eliminate the individual difference of condition setting programming. CONSTITUTION:The oscillation controller is provided with a keyboard switch 11, from which a frequency target oscillation quantity and other numerical data are inputted, and a touch switch 12 which selects an operation mode or the like, and information of these switch groups are subjected to code conversion in a parallel I/O interface 13 and are stored in an RAM 15A of a main control part 15. A CPU 15C displays data from switches 11 and 12 on a display device 16 in accordance with a program in an ROM 15B to control a digital sine wave oscillator 20. The output of the oscillator 20 is subjected to D/A conversion by a converter 23, and the magnitude of the output is controlled by a multiplication- type D/A converter 25, and a sample 31 of an oscillation generating machine 30 is excited with a current attained by amplifying the output in an amplifier 29. The oscillation quantity detected by an acceleration sensor 32 of an oscillating table is amplified by a charge amplifier 33 and is so controlled by the CPU 15C that it coincides with data set by the switch 11.
