Title:
SYSTEM FOR CHANGING OVER AZIMUTH MEASURING APPARATUS
Document Type and Number:
Japanese Patent JPH01178811
Kind Code:
A
Abstract:
PURPOSE:To prevent the generation of disorder caused by the erroneous change over the operation of an azimuth measuring apparatus, by outputting a signal for synchronizing/changing over the azimuth signal of the azimuth measuring apparatus when an operating signal is received and performing change-over control after tuning. CONSTITUTION:The contact signal of a use system selection switch 90e1b is guided to a tuning order control part 90e2 and a tuning start display part 90e is allowed to light to output a change-over control signal to a change-over control part 90b. The change-over control part 90b outputs a change-over signal to a change-over element 4b to make an azimuth signal synchronous. After the finish of tuning, a tuning finish display part 90e5 is allowed to light and a change-over signal is outputted to a change-over actuator 90f and a rotary solenoid 90f1 is operated to change over a gyroscopic change-over element 6b toward a gyrocompass 1b. After the finish of change-over, a tuning finish display part 90e4 puts out lights and a use system display part 90c2 lights and the change-over element 4b is changed over from a contact (d) to a contact (c).
