Description
Technical field:
The present invention relates to electronic device field, particularly relate to a kind of fixed photoelectric measure speeding sensor.
Background technology:
Tachogenerator is the instrument measuring measured object travelling speed.The increment of unit interval intrinsic displacement is exactly speed.Speed is vector, has size and Orientation, and the size of speed is called as speed, and speed comprises linear velocity and rotary speed, and what correspond just has slotted line speed pickup and measure rotary speed sensor, and they are collectively referred to as tachogenerator.
Nonopaque type tachogenerator is made up of with holes or breach return dish, light source and photoelectric tube.When disk rotates with measured axis, light can only by being irradiated on photoelectric tube because of hole or breach.When photoelectric tube is illuminated, its back resistance is very low, so export an electric impulse signal.When light source is covered by disk, photoelectric tube back resistance is very large, and output terminal does not just have signal to export.Like this, according to the hole count on disk or breach number, the rotating speed of measured axis can be measured.Disc hole or breach number are taken as still usually, and when therefore measured axis often circles, photoelectric transformer is exportable 60 pulse signals just.If the time-base signal getting electronic counter is 1s, then can directly read measured axis rotating speed.
The principle of reflective tachogenerator is the same with Nonopaque type,, by photoelectric tube, the change of the light of impression is converted to change in electric, but it obtains pulse signal by the reflection of light, the measuring point normally reflectorized material being pasted on measured axis forms reflecting surface.Conventional reflecting material is the special reflection paper tape that tests the speed, and also can replace with reflectorized materials such as aluminium foils, sometimes can also be coated with white paint as reflecting surface at tested position.Light projector and reflecting surface need suitably to configure, and distance is 5-15M between the two usually.When measured axis rotates, photovalve accepts pulsating photograph, and exports corresponding electric signal and to make a gift to someone electronic counter, thus measures the rotating speed of measured axis.
The waveform comparison of photo electrical tacho generator output signal is regular, and be near the mark square wave, and almost state no interference signal produces.But Nonopaque type can make light source life reduce due to vibrations, thus has under the condition compared with strong motion and should not adopt.Simultaneously traditional photo electrical tacho generator ubiquity reaction is insensitive, the problems such as reliability is low.
Summary of the invention:
In order to solve the problem, the invention provides a kind of structure simple, equipment precision is high, is quick on the draw, practical technical scheme:
