Sampling resistor R1 is 300 Ω, and sampling resistor R2 is 300 Ω, and sampling resistor R3 is 50 Ω, and sampling resistor R4 is 50 Ω.
Rigid body around a fulcrum high-speed rotation is referred to as gyro.Usually said gyro is to refer in particular to symmetric top, and it is a uniform quality distribution, has the rigid body of axisymmetric shape, and its geometirc symmetry axis is exactly its axis of rotation.Got by fly hind wing (specialization is balancer) is bionical.The principle of gyroscope is exactly, and the direction of the rotary shaft indication of a rotating object, when not affected by external force, will not change.People, according to this reason, keep direction with it, and the thing manufactured just is gyroscope.We are the most in fact also with this principle.Wheel turns to be less susceptible to down the soonest, because axletree has the strength of one holding level.Its power operationally to be given by gyroscope, makes it quickly rotate, and typically can reach hundreds of thousands per minute and turn, can be with work really long days.Then read the direction indicated by axle by multiple method, and automatically data signal is passed to control system.In actual life, the feed motion that gyroscope occurs is to occur under the effect of gravity torque.
According to the characteristic of gyro high speed rotating, improve the duty instrument of gyro logging instrument.Can control gyroscope according to the instruction of host computer and work in big rate mode and little rate mode, big rate mode is lifting pattern, and downhole instrument does not gather data, reduces power consumption, extends the service life of instrument；Little rate mode, downhole instrument controls the hitting turning point of gyro, gathers multi-group data at 0 ° and 180 ° respectively, the method using data to process, and chooses useful data computer azimuth, hole deviation etc., utilizes turning characteristic elimination error；
Function switching signal CR signal is sent by communication board, is used for controlling Product Status switching (" 1 " is 3.3V ~ 5V voltage, and " 0 " is less than 0.5V voltage, with DGND for reference to ground).When CR signal is " 1 ", then gyro inlet point surveys pattern, state of i.e. logging well (under this state, gyro is used for differentiating earth angle rate signal, it is impossible to follow the tracks of big input angle speed, and it allows 3 °/s of input angle speed)；When CR signal is " 0 ", then gyro enters lifting pattern (under this state, gyro resolution reduces, it is impossible to differentiates earth angle speed, but there is bigger angular speed input, it is ensured that during gyro lifting, vibrations received and impact will not produce damage to gyro).
Status feedback signal TR is sent by servo circuit plate, for system response product duty at that time；" 1 " represents that product work is surveying a pattern, " 0 " represent your product work lifting pattern (" 1 " is 3.3V ~ 5V voltage signal, and " 0 " be less than 0.5V voltage signal, with DGND be with reference to).
Gyro output is main by sampling resistor of connecting on gyroscopic couple device, and torquer electric current is converted into voltage output.During well logging state, sampling resistor is designed as 300 Ω, now gyro has higher resolution, earth rate can be told thus settle accounts for orientation, but owing to Increasing of Servo Power Amplifier voltage max is 15V, therefore can be that the maximum current that torquer provides receives restriction, therefore gyro cannot follow the tracks of bigger input angle speed；During lifting pattern, sampling resistor becomes 50 Ω, and gyro resolution reduces, but owing to sampling resistor reduces, 15V power amplifier can be that torquer provides bigger operating current, and therefore according to big angular speed input, gyro can ensure that gyro is not damaged by.
In Fig. 2, L1, L2 are dynamic tuning gyroscope instrument torquer coil (20 ± 2 Ω).When gyroscope exists turning rate input, servo loop applies to control electric current to torquer coil, forms control moment, makes gyro to measure element tracks input angular velocity, forms closed-loop path.Can be characterized the size of gyroscope sensitivity angular speed by the electric current of L1, L2, the current signal of L1, L2 is converted into the voltage signal output signal as gyroscope sensitivity angular speed by sampling resistor R1, R2, R3, R4.
YLH, YLL, XLH, XLL represent the high low side of dynamic tuning gyroscope instrument two-way torquer respectively.U1 and U2 is optocoupler and device (internal be made up of light emitting diode and phototriode), due to internal not physically connected, can well suppress noise, has the volume advantage such as by force little, contactless, anti-interference.K001 position relay, carries out switch switching by the height of control signal.R1, R2, R3, R4 are sampling resistor.When communication board CR signal is " 1 ", diode within U1 is not turned on, U1 is caused not work, YLL and XLL passes through resistance R1(300 Ω) and R2(300 Ω) difference ground connection, TR signal is low level due to U2 input signal, be U2 does not works, TR signal remains at high level state, i.e. one state, thus gyro is maintained at a survey pattern, when i.e. well logging state old party communication board CR signal is " 0 ", U1 works, YLL and XLL passes through resistance R3(50 Ω) and R4(50 Ω) ground connection, U2 input has high level signal, U2 is worked, TR signal drags down and becomes low level, it is " 0 ", gyro is operated in lifting pattern.
Understand, trail angle speed with sampling RC be inversely proportional to, when RC get over hour, electric current is the biggest, and the angular speed of tracking is the biggest, and vice versa；I.e. under some survey pattern, following rate is little, and under lifting pattern, following rate is big.
This well logging flexible gyroscope, in the case of gyrostat is not transformed, uses this measurement pattern, by the improvement on circuit, it is achieved that gyrostat be not required to power down static in the case of, carry out instrument on carry or transfer.After which eliminating a survey, gyrostat needs the static time.It is greatly saved the log-time of individual well gyro, alleviates instrument and repeatedly power on the impact to electric elements, substantially prolongs the service life of electric elements and gyro.It is more importantly the labor intensity significantly reducing the upper well of personnel.
