Title:
OPERATION CONTROLLER FOR ELECTROMAGNETIC PUMP
Document Type and Number:
Japanese Patent JPS57152006
Kind Code:
A
Abstract:
PURPOSE:To drive an electromagnetic pump accurately, by counting a pulse from an oscillator with a preset counter executing a processing routine with an interrupting signal given to a microcomputer when the counted value is coincident with a set value. CONSTITUTION:The result of operation of a microcomputer 1 is set to a preset counter 9, and when the counter 9 counts pulses from an oscillator 3 and the value reaches a count set value, the count output is amplified at a pump driving circuit 7 via a waveform shaper 6 to drive an electromagnetic pump 8. Simultaneously, the count output is given to the computer 1 as an interference signal and an interruption processing routine is executed with a preset program. This processing is operated with a data given from the computer 1 extenally, a frequency data to drive the pump 8 is written in a memory and the data to drive the next pump 8 is transferred to the counter 9. Thus, the pump 8 can be driven in response to the result of the operation of the computer 1.
