For ripple detection instrument, the precision of amesdial is relatively low, it is impossible to meet the requirement of measurement high-precision workpiece.And existing amesdial
Structure limits the possibility that it lifts precision.
Electronic compass, also known as digital compass, electronic compass can be divided into flat electronic compass and three-dimensional electronic compass.Plane
Electronic compass requires that user must keep the level of compass when in use, otherwise when compass run-off the straight, can also provide course
Change and actually course is not changed.Although requiring very high when flat electronic compass is to using, but if can guarantee that sieve
Carrier appended by disk is all the time if level, and plane compass is that a kind of cost performance is selected well.Three-dimensional electronic compass overcomes plane
Electronic compass strict limitation in use, because three-dimensional electronic compass adds obliquity sensor inside it, if electronics
During compass run-off the straight slope compensation can be carried out to compass, accordingly even when compass run-off the straight, course data still accurate nothing
By mistake.Sometimes for overcoming temperature drift, compass also can built-in temperature compensation, reduce inclination angle to greatest extent and point to the temperature at angle
Drift.Widely used is three axle strapdown reluctance type Digital Magnetic Compass, and this compass has anti-shake and vibration resistance, course precision
It is higher, have the advantages that electronic compensation to interference field, be desirably integrated into control loop progress data link, thus be widely used in
The fields such as Aeronautics and Astronautics, robot, navigation, vehicular autonomous navigation.
Marine Geology research institution is used for the seismic survey instrument of detecting deep crustal motion, when being debugged before it dispatches from the factory,
The electronic compass integrated to instrument internal is needed manually to be demarcated, the corner accuracy needed during due to demarcation is high, every millisecond
Rotation error cannot be greater than 1/10000 degree.Individual in the prior art, there is no can be directly to complete returning for above-mentioned demarcation operation
Turn equipment, related apparatus for rotating velocity of rotation and corner accuracy are all unable to reach use requirement.
