Shell bears air pressure Realtime Alerts method
Technical field
The present invention relates to computer control fields more particularly to a kind of shell to bear air pressure Realtime Alerts method.
Background technique
General stationary film projectors are made of the part such as transmission, film trasport, optics, playback, body and electric appliance.Movable type is put
Not with sound amplifier, loudspeaker etc. on film projector.The effect of cinematographic projector each section is as follows:
Running part: supplying kinetic energy by motor, passes to film trasport portion through gear, sprocket wheel, toothed belt, turbine worm etc.
Point.In fixed multi-purpose three-phase synchronous motor;Monophase machine is generally used in movable type;Special type is generally required with connection
Motor is locked, it is synchronous between equipment to guarantee.
Film trasport part: coiled film is sent to gate irradiation by feed disk to mirror picture, and makes light through playback part
It learns vocal cord signal and is converted to audio-frequency current.Then the film shown is wound again.It by supply, receiving can (or piece arm) and
Feed, interval, the sprockets such as take up, the composition such as intermittent motion mechanism, various pulleys, film gate and picture frame width regulating device.Narrow glue
Piece movable type projector is mostly used interval in-and-out movement and replaces intermittent film transport gear.The core of cinematographic projector is intermittent movement
Mechanism, continuous rotation is become intermittent rotary by it, and is matched with barn door, rests on film steadily when light passes through
At gate, blur-free imaging is in screen;It is quickly pulled down when light is occluded, in order to avoid expose trace when film movement.Standard electric
Shadow movement speed is 24 lattice/second, and in order to reduce scintillation effect, the every lattice shading of barn door twice, flicker frequency is increased to per second
48 times.Most popular intermittent motion mechanism is Ma Erdi cross vehicle
Have a guide pin 2 on the cam 1 of continuous rotation, it often with cross vehicle 3 is radially slotted engages primary, cross vehicle just revolves
Turn 1/4 week, therefore transmission shaft every revolution (by a~e), just 90 degree of the rotation of intermittent film transport gear 4, and film is pulled into a lattice.
For cam during e → a → b, cross vehicle is static.Certain narrow gauge projectors do not have to machine using optics intermittent compensation
Tool indexing mechanism is conducive to protect film, but picture brightness damages.Slice receiving mechanism of slice is increased with piece coil diameter and speed slows down, with
Reduce tension.
Opticator: it is made of light source, reflective or condenser, projection lens, lamp box, ventilation and heat mechanism etc..Work as film
In gate intermittently staying, opticator illuminates the frame in frame window, and is amplified by projection lens, is incident upon in screen.
Different screen sizes and screen distance, using the projection lens of different focal length;When projection deformation wide screen film, separately widen screen
Camera lens.Light source also difference due to projector purposes is different, such as incandescent lamp, bromine tungsten filament lamp, xenon lamp.Light source power is high when screen is big.
Playback part: the acoustic information that optics on film or magnetic track record is reduced into tone currents, through sound amplifier
Or loudspeaker is converted into sound.This part is made of exciter bulb, excitation camera lens, light sword, photoelectric tube, vibration absorber or magnetic head.
Some narrow gauge projectors also install erasure and magnetic recording head additional in this part for the ease of voluntarily dubbing.
Body part: being the frame of support and connecting components.Generally to install electrical equipment, conducting wire etc. in rack.
Exterior panel or surface are equipped with instrument, indicator light and Operation switch etc..

Bear in air pressure real-time alarm system in the shell: the domain identification equipment is in the power scenario image
Pixel gray value to each pixel of its neighborhood gray value mean value departure degree be more than limitation when, determine that it is side
Edge pixel.
Bear in air pressure real-time alarm system in the shell: the air pressure alarm equipment includes that voice plays chip and lamp
Optical drive apparatus, the voice plays chip and the light driving equipment is all connect with the pressure sensor.
Bear in air pressure real-time alarm system in the shell: the voice plays chip for indoor in the review of a film by the censor
When real-time air pressure is transfinited, playing transfinites corresponding audio alert file with air pressure;
Wherein, the light driving equipment carries out different colours based on the specific value of the indoor real-time air pressure of the review of a film by the censor
Light drive operation.
In addition, being born in air pressure real-time alarm system in the shell: the frequency duplex communications that Frequency Division Duplex device uses
Mode, that is, fdd mode, its main feature is that on two symmetrical frequency channels of separation (uplink and downlink frequency interval 190MHz), system into
Row receives and transmission, reception and transmission channel is separated with protection frequency range, while can also break through for two generations using technologies such as packet switch
The bottleneck of development realizes high-speed data service, and the availability of frequency spectrum can be improved, and increases power system capacity.But FDD must be using pairs of
Frequency, i.e., in the bandwidth of every 2x5MHz provide third generation business.Which can make full use of when supporting symmetrical service
The frequency spectrum of downlink, but when asymmetrical packet switch (internet) works, the availability of frequency spectrum then substantially reduces (due to low uplink
Load causes the availability of frequency spectrum to reduce about 40%), in this regard, the advantage that tdd mode has FDD incomparable.
Air pressure real-time alarm system is born using shell of the invention, it is not high for projection equipment reliability in the prior art
And played data acts the technical issues of degree can not be recognized effectively, the real-time air pressure born for the shell of projection equipment carries out
Measurement improves the reliability of projection equipment to carry out different alarm operations based on the real-time air pressure;Using what is automatically analyzed
Mode carries out field assay to the movement rank of the film broadcasting content of current detection, avoids causing film inspector's eyes
Damage;Edge noise performance is eliminated better than opening and closing operation processing and opening and closing operation processing protection mesh using corrosion expansion process
Characteristic of the details better than corrosion expansion process is marked to have built and be based on the basis of carrying out noise profile situation analysis to image
The Morphological scale-space mechanism of image content features overcomes the originally stiff various defects of image procossing mechanism bring, thus
Solves above-mentioned technical problem.
