Description
Technical field
The utility model relates to the dynamic analysis device systems of a kind of automated test device, particularly a kind of rate gyroscope.
Background technology
Rate gyroscope is used for induction and imports axial angular velocity along it, and exports proportional with it simulating signal, is widely used in the vehicles such as aircraft, boats and ships and automobile.Under some harsh environment for use, as the guidance of guided missile, rate gyroscope need satisfy certain dynamic perfromance usually, therefore need test gyrostatic dynamic perfromance when producing, as frequency characteristic, step response etc.
Method of testing commonly used is: use the swing of Swaying Test Platform analog sine, test its amplitude versus frequency characte by frequency characteristic analyzer; Use the anxious platform and notes instrument or oscillograph of stopping to test its step response, obtain parameters such as rise time, damping ratio.But this method need be bought specialized apparatus and instrument, and investment needs place and maintenance than big and equipment.
By at the inner self check coil that increases of gyroscope, and feed electric current to the self check coil, can simulate the angular velocity signal of extraneous input, make gyro produce deflection along the output shaft direction, thereby obtain exporting Dynamic Signal.This mode is simple relatively, has replaced tilter, has suddenly stopped equipment such as platform with the mode of current excitation, but still needed equipment such as signal generator, notes instrument and spectrum analyzer, is difficult for carrying and carries when the transition test.
The utility model content
The utility model purpose: at the problems referred to above, the purpose of this utility model provides a kind of simple, portable device systems that the dynamic perfromance of rate gyroscope is analyzed.
Technical scheme: a kind of dynamic analysis device systems of rate gyroscope, comprise computer, the circuit board that data collecting card is housed, the gyroscope that has the self check coil, described data collecting card is connected by cable with described circuit board, described circuit board carries out power amplification with the output signal of described data collecting card, can drive described gyrostatic electric current to produce, described gyrostatic output signal is gathered by the analog input port of described data collecting card.
Described data collecting card is PCMCIA-6036E.
Beneficial effect: compared with prior art, the utility model has the advantages that by computer, data collecting card and simple circuit design and realize rate gyroscope is carried out dynamic characteristic test, with respect to conventional test methodologies, have realize simple and easy, be convenient for carrying characteristics such as test result is directly perceived.
Description of drawings
Accompanying drawing is the utility model system logic synoptic diagram.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only is used for explanation the utility model and is not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims institute restricted portion to the modification of the various equivalent form of values of the present utility model.
As shown in drawings, a kind of dynamic analysis device systems of rate gyroscope comprises computer 2, the circuit board 3 that PCMCIA-6036E data collecting card 1 is housed, the gyroscope 4 that has the self check coil.Data collecting card 1 and circuit board 3 are connected by cable, circuit board 3 is used for the output signal of data collecting card 1 is carried out power amplification, to produce the self check coil of enough current drives gyroscopes 4, the analog input port of data collecting card 1 is gathered the output signal of gyroscope 4 simultaneously.
Because the analog output turnover rate of PCMCIA-6036E data collecting card 1 is 1024 samples/sec, can not produce the upper frequency sine wave, usage counter is short mouthful for this reason, the exportable upper frequency square wave of counter, through emulation and actual testing authentication, use square wave and sinusoidal wave as pumping signal, the test effect is in full accord.If adopt the data collecting card of higher turnover rate, can use the directly high-frequency sinusoidal signal of output of analog output mouth.
The software of realizing the utility model operation uses the graphic programming instrument LabVIEW of NI to write.Use this software to produce at the counter port of data collecting card: 1, frequency is that 1～500HZ continually varying square-wave pulse signal is used for frequency characteristic test, and frequency increment can be by the software setting; 2, step signal, namely the rising edge of square-wave pulse or negative edge are used for the step response test.Pumping signal carries out importing gyrostatic self check coil after the power amplification through circuit board, gyroscope can produce corresponding output signal, output signal is connected to the analog input port of data collecting card, software can be gathered and wave recording and carry out analytical calculation and draw amplitude-frequency, phase frequency curve, and the parameter of system's rise time, overshoot and damping ratio.
This software comprises following functional module:
Make data acquisition be stuck in the pulse signal of the counter port generation certain frequency of appointment by the DAQmx module, obtain the voltage signal of gyroscope output to be measured at the analog input port of appointment, can carry out the scan round of a plurality of frequencies by For or While circulation;
From the data of gathering, calculate frequency, amplitude and the phase place of gathering signal by Extract Tone module, be that horizontal ordinate amplitude, phase place are ordinate again with the frequency, use the XYGraph module in software, to draw frequency characteristic, by retrieval, near 0HZ amplitude 0.707, be the frequency band of system in the output signal amplitude of all frequency component correspondences;
By Transition Measurement module, can obtain rise time and the overshoot of system, because system is similar to 2 rank underdamping systems, can further calculate the damping ratio of system according to formula.
