Under the conditions of rate gyroscope combined test inspection requirements.
The technical solution of the present invention is:
A kind of gyro duty self-check system, it is characterized in that: include being arranged on the X within gyroscope,
Y, Z road self-inspection coil, be arranged on the self-test signal circuit within tester, on and off switch K1, select switch
K2, control computer；Described self-test signal circuit is constant-current source circuit；Described on and off switch K1 is used for controlling
Whether self-test signal exports；Described selection switchs K2 for controlling which gyro self-inspection letter signal exports to
Self-inspection coil；Described X, Y, Z road self-inspection coil is for producing the disturbance torque of X, Y, Z gyro respectively；
Described control computer receives and processes the output signal that gyro is corresponding.
Above-mentioned constant-current source circuit is output as the direct current signal of 50 ± 2mA；The described threshold range set is as 5.5
±1.5°/s。
A kind of gyro duty self-sensing method, comprises the following steps:
1) constant-current source circuit produces constant direct current self-test signal；
2), in the self-inspection coil of X, Y or Z road gyro that this direct current self-test signal sends into gyroscope, produce dry
Disturb moment；
3) gyroscope sensitivity disturbance torque, exports an output signal corresponding to this self-test signal；
4) this output signal is compared with setting threshold value, thus judge that gyro the most normally works.

Help.
Accompanying drawing explanation
Fig. 1 is the theory diagram of the present invention.
Detailed description of the invention
The equipment that the present invention mainly uses is rate gyroscope combined unit tester.Main from software and hardware two side
Face realizes above-mentioned functions.In the case of rate gyroscope combined stationary and closed circuit working, by applying to product
The self-test signal of certain fixing magnitude, makes rate gyroscope combined system disturbance torque occur, in closed loop feedback system
System is formed final output；Output data separating according to rate gyroscope combination goes out corresponding to self-test signal
Output signal；By software, output signal calculated and compare with input signal, to confirm gyro
The most normally feed back this input self-test signal, in this, as the foundation judging that gyro the most normally works.
The principle of the invention:
The present invention is at one piece of constant-current source circuit of tester indoor design, and the output of this circuit is as self-test signal
Input quantity, selects a certain road of speed control Gyro to detect by switch.
The gyroscope indoor design that the present invention combines at rate gyroscope self-inspection coil, by self-inspection coil
Injection current, thus gyroscope is applied disturbance torque, through the closed feedback system within rate gyroscope combination
System, forms final output signal.
Output signal is sent into and is controlled computer (being included in tester) by the present invention, is believed with self-inspection by software
Number carry out the comparing calculation of polarity and amplification, and compare with the normal range set, whether draw
Qualified conclusion.Wrong data red display is proposed warning, and provides the prompting of " defective ".
As it is shown in figure 1, self-test signal circuit one the 50 ± 2mA of output in rate gyroscope combined unit tester
Direct current signal.Whether this signal of K1 on-off control exports.Which top this signal of K2 on-off control exports to
Spiral shell.Control computer acquisition to after gyro output signals, judge whether to meet 5.5 ± 1.5 °/s by software
Scope.If in the range of, export " qualified " printed words；If going beyond the scope, " do not conform to red display
Lattice " printed words.
Present invention achieves the Autonomous test of the gyro that works under resting state, meet the gyro test after the assembling of whole bullet and cover
Lid inspection requirements, and by checkings such as dynamic environmental test and target range whole bullet auxiliary tone tests, reached expection
Purpose and requirement.
