This circuit working principle is as follows:
1, when gyro sphere and tracking ball are complementary
Signal transformer BS primary coil 30,31 produces equal and opposite in direction to centre tap, the 330HZ signal voltage that phase place is opposite.Wherein by 30 signal voltage V to the centre tap
30The loop that produces at a last electric bridge is:
When the positive half cycle of signal, electric current is through 30 → D
1→ C
1→ R
1→ centre tap is at C
1On just produce negative down half-wave DC voltage; When the signal negative half period, electric current is through centre tap → R
1→ C
2→ D

2Interior 110V, 50HZ AC current direction to change the rotation direction of gyro sphere, reach to presetting the purpose that true heading is rotated.
The conversion control circuit principle of work is as follows:
1, when gyro sphere and tracking ball are complementary
By phase depending on rectification and tracking circuit as can be known, pull-up resistor R at this moment
2, R
3On direct-flow signal voltage phase isopolarity opposite, polarized relay J
3Two working coils produce the electromagnetic attraction of opposite sign but equal magnitude, make the middle contact of relay neither upwards also closed downwards, therefore, and pilot relay J

8Excitatory for the 110V50HZ alternating current, the main and sub-coil electric current produces rotating magnetic field, makes the gyro sphere brass housing that is in this magnetic field produce eddy current, and this eddy current interacts with rotating magnetic field again and produced electromagnetic torque.
Before just startup gyrocompass and gyro sphere are not energized, this electromagnetic torque will make gyro sphere do the orientation rotation, and under above-mentioned assumed condition, anti-spiral shell ball will can arrive in common 20 seconds and preset on the true heading to the little direction rotation in course.
Because gyro sphere is suspended in the liquid, it is very faint that gyro sphere rotates the fluid friction moment that produces, so its rotatory inertia will make gyro sphere break through the equilibrium position to rotating a mismatch angle less than presetting the true heading direction.Because the closed loop of system is controlled automatically, this moment, system produced reverse mismatch signal again, through phase depending on rectification, made J again
3The downward closing of contact of middle contact, connect pilot relay J
2, its loop:
+ 15V → R
9→ J
3Middle contact → J
3Lower contact → J
2Coil → ground
Relay J
2Work, (this moment is because J for two normally opened contact closures

2→ J
2Following normally opened contact → K
8→ S contact → F
2→ 130
Obviously the direction of current that flows through secondary coil is with aforementioned opposite, and the rotating magnetic field direction of generation is also opposite, and gyro sphere will promptly preset the revolution of true heading direction to increasing the course.Along with reducing of amplitude of fluctuation, rotatory inertia also reduces thereupon, and process several hunting period of gyro sphere just has been controlled on the true heading that presets.A large amount of tests show, are controlled in time on the true heading generally about 50 seconds from starting to gyro sphere.

The delay circuit principle of work is as follows:
When switch places " normally " position, K
1, K
3Closure, 27-27 ', 28-28 ' be by switch connection, gyro sphere starts when just starting compass, so the time can not quicken automatically to start.
When switch places " automatically " position, K

3Disconnect, when just starting compass because delay circuit has direct current signal output, thus two relays do not work, its contact (27-27 '), (28-28 ') disconnection, gyro sphere can not be powered.
Choose different capacitor C
5And resistance R
5Value, can change time of time delayed signal output, promptly can control gyro sphere and start needed time delay, native system is set at 2-4 minute, is enough to guarantee that gyro sphere was controlled on the true heading before energising.After starting about 2-4 minute, delay circuit is promptly exported direct current signal, adds to solid-state relay J
4J
5, the actuating of relay, two contacts (27-27 '), (28-28 ') closure, connect gyro sphere 120V330HZ three-phase alternating-current supply, the gyro motor running, gyro sphere begins to set up momentum moment H.
Usually, gyro sphere energising instantaneous, gyro sphere can depart from the certain angle of true heading, but system is under closed-loop control, and following the tracks of mismatch signal can make gyro sphere turn back in the range of control once more.But, (momentum moment will increase with the rising of gyro motor rotating speed because gyro sphere has had momentum moment H, about 10-15 minute, reach ratings), according to the gyroscope characteristic as can be known, the electromagnetic torque M that be added on the gyro sphere vertical axial this moment can not directly make it make azimuth rotation to the true heading direction, but make the gyro sphere main shaft around its horizontal axis electromagnetic torque direction precession.Produce elevation angle θ by precession, the gyro sphere that center of gravity is moved down produces the gravitational torque M θ along horizontal axis, thereby makes gyro sphere around the slow precession of vertical axial true heading direction.In other words, the gyro sphere with momentum moment is sought true heading by gravitational torque.In the time of in it turns back to the true heading range of control once more, electromagnetic torque disappears, but center of gravity moment still exists, so continuing precession probably, gyro sphere goes out the Be Controlled scope again and mismatch, reverse mismatch signal produces reverse electromagnetic torque M once more, gyro sphere elevation angle θ is slowly reduced round about, until θ angle reversion, gyro sphere is again under reverse gravitational torque M θ effect, once more to the equilibrium position---and true heading is returned precession.So repeatedly, through the swing in several cycles, gyro sphere has been stabilized on the true heading the most at last, shows through a large amount of tests, approximately needs 30-50 branch clock time from starting compass to gyro sphere stable (precision ± 1 ° 0).

The 110V50HZ single-phase alternating current, provides+the 15V DC voltage to delay circuit and conversion control circuit through stabilized voltage supply to the power supply of this device by master compass binding post 130,131.
Because gyro sphere course and master compass tracking ball course are inconsistent, the mismatch signal of tracking is promptly arranged from 30,31 outputs, its marking current differs in size through the induction electromotive force that BS goes up the lower coil generation, through phase-sensitive rectifier circuit at pull-up resistor R
