Description
Technical field
The utility model belongs to avionics field, particularly relates to a kind of magnetoelectric tachometric transducer exerciser.
Background technology
Magnetoelectric tachometric transducer is mounted on Helicopter Main Reducer, together with taking turns with the hum on being configured in helicopter, for survey aircraft minimax gyroplane rotate speed.Warning when aircraft reaches minimum and maximum rotating speed is responded to by GCZ-3A gyroplane rotate speed Magnetic Sensor.As can be seen here, magnetoelectric sensor plays vital effect in gyroplane rotate speed system, before installation, must carry out verification to it, ensures that it is functional, otherwise can affect the work of whole rotary speed system.Also there is no at present the checkout equipment for this component.
Summary of the invention
Goal of the invention: a kind of magnetoelectric tachometric transducer exerciser is provided, can tests sensor performance, avoid fault product directly to install, thereby improve efficiency and the quality of aircraft general assembly.
Technical scheme: a kind of magnetoelectric tachometric transducer exerciser, comprise rotation speed source 1 and phonic wheel 2, described rotation speed source 1 comprises primary power 101, control gear 102 and actuating unit 103, described actuating unit 103 and phonic wheel 2 mechanical erections.
Described actuating unit 103 is motor.
Described control gear 102 comprises touch screen 102a and frequency converter 102b, adopts nine needles serial port to connect and control between touch screen 102a and frequency converter 102b.
Beneficial effect: the utility model is reasonable in design, staff is in the time of detecting sensor, outside connection simply, easy and simple to handle.This exerciser can be tested sensor performance on the one hand, avoids fault product directly to install, thereby improves efficiency and the quality of aircraft general assembly, has simplified on the other hand test routine, has improved work efficiency.And this exerciser also has compatibility.

Fig. 2 is the utility model test connection layout;
Fig. 3 is the utility model test principle figure.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, refers to Fig. 1 to Fig. 3.
A kind of magnetoelectric tachometric transducer exerciser, comprises rotation speed source 1 and phonic wheel 2, and described rotation speed source 1 comprises primary power 101, control gear 102 and actuating unit 103, described actuating unit 103 and phonic wheel 2 mechanical erections.
Described actuating unit 103 is motor.
Described control gear 102 comprises touch screen 102a and frequency converter 102b, adopts nine needles serial port to connect and control between touch screen 102a and frequency converter 102b.
Rotation speed source 1 is the drive source of whole exerciser.Phonic wheel 2 is cores of whole exerciser, and its effect is to follow actuating unit 103 motors to rotate together, then makes Magnetic Sensor sense tach signal.The effect of primary power 101 is to carry out basis power supply to whole exerciser, provides operating voltage to exerciser.The effect of 102a touch screen is to carry out procedure operation, sends work order, makes actuating unit 103 motors carry out work.The effect of 102b frequency converter is the three-phase alternating current that the single-phase alternating current of primary power 101 is become to actuating unit 103 machine operation, for it provides operating voltage.Frequency converter 102b is directly connected with touch screen 102a by nine needles serial port simultaneously, can directly receive like this work order of being sent by touch screen 102a, makes actuating unit 103 machine operation.The effect of actuating unit 103 motors is to provide tach signal after receiving the work order of being sent by touch screen 102a, and then drives phonic wheel 2 to work together.
Process of the test: primary power 101 connects rotation speed source 1 after 220V just electricity, but does not connect, press lower switch after rotation speed source 1 connect, now frequency converter 102b powers on, actuating unit 103 motors also power on, but do not have instruction not work.Power module G2 powers on, and connects touch screen 102a.By touch screen, 102a operates, and by nine needles serial port, instruction is sent to frequency converter 102b, sends instruction machine operation by frequency converter 102b to actuating unit 103 motors.Actuating unit 103 driven by motor phonic wheels 2 are worked together.
Below in conjunction with accompanying drawing, the utility model is elaborated.
With reference to figure 3, by external primary power 101 220V power supply, through Illuminated Switch S9,220V electricity is added to 91,92,95 pins of frequency converter 102b, also give power module G2 power supply simultaneously.After frequency converter 102b, by 96,97,98,99 pins, three-phase electricity is added on actuating unit 103 motors and is powered to motor.Primary power 101 becomes 24V direct current to touch screen 102a power supply after G2, makes its work.
Test pacing items:
Phonic wheel 2 technical parameters: 30 teeth, tooth pitch 20mm.
The gap of sensor and phonic wheel 2: 0.12 ± 0.01mm
1) before energising, check
Connect the line by Fig. 2, check that whether wiring is firm.
First rotation speed source 1 is received in 220V AC power.
2) performance test
Output voltage: at output terminal external load resistance 100K Ω, electric capacity 250PF.In the time that rotating speed is 2540r/min, measure the voltage of output, scope should be at (30-70) VP-P.
3) after being completed, close instrument power source, remove cable and wire, put instrument in order.
