Abstract

The utility model provides a photography time delay controller, which comprises a casing, wherein an operation keyboard and a display screen are arranged on the casing, a singlechip electrically connected with the operation keyboard and the display screen, and a voltage stabilizer electrically connected with the singlechip are arranged in the casing. The photography time delay controller is characterized in that a sensor input interface and an output controller electrically connected with the singlechip are respectively arranged on the casing. Objects to be shot and ambient environment can be detected through probes such as infrared ray, laser, microphones and the like, detected signals are transmitted to the singlehcip through the sensor input interface to be processed, and the starting of the controller is controlled through the singlechip, so the synchronous precise control on a flash lamp and a shutter is realized, and meanwhile, an electromagnetic valve can also be controlled to generate precise and controllable liquid drops. Thereby, the shooting on the liquid drops with different sizes at different speeds can be realized, and the requirement on the shooting environment can be reduced, so the shooting successful rate is improved, the parameter setting and regulation is simple and clear, the maneuverability is high, the structure is simple, the cost is low, and the expansibility is good.

Description

The photography overrun control

Technical field

The utility model provides a kind of overrun control, and especially a kind of photography overrun control belongs to photograph utility appliance technical field.

Background technology

In photographic process, especially in high-speed photography, very important problem is will control flash of light to take place to open the synchronous of the moment with shutter constantly, to obtain best shooting effect.Being used to cause the flashlamp flash of light device synchronous with taking phenomenon at present has: use the shot object motion parts to remove to be switched on or switched off conductive contact; The sound that sends with acoustic pickup inspected object motion process (as collision), and produce electric pulse with testing result; Use shot object to switch on or off the light beam that leads to photovalve, thereby produce electric signal etc.This type of device only can reach and draw the sudden strain of a muscle function, can not constantly control flash of light.An other class device is on the basis of said apparatus, has installed delay circuit (for example monostalbe trigger etc.) additional, can realize the control constantly of glistening.But this type of device is made of mimic channel usually, and the circuit complexity can not reach the accurate control of time.Above-described well known device all fails to reach the interlock of flash of light and shutter.Therefore it is low to cause taking success ratio, and the apparatus structure complexity that has is strict to shooting condition, uses inconvenient.

Summary of the invention

For overcoming all deficiencies that above-mentioned well known device exists, the utility model provides a kind of photography overrun control.

The utility model is finished by following technical proposal: a kind of photography overrun control, comprise that ribbon gymnastics on it makes the housing of keyboard and display screen, be provided with the single-chip microcomputer that is electrically connected with operation keyboard and display screen in the housing, and the voltage stabilizer that links to each other with monolithic electromechanics, it is characterized in that being respectively equipped with on the housing and dynamo-electric sensor input interface and the o controller that links to each other of monolithic.

Described sensor input interface is a Schmidt trigger, Schmidt trigger is by switching diode and sound probe or infrared probe or the movable grafting of laser probe, finish incoming level conversion and input voltage shaping, and detect the motion state of subject by sound probe or infrared probe or laser probe, produce the acceptable detectable voltage signals of single-chip microcomputer, and send single-chip microcomputer to handle through the sensor input interface detected signal.

Described o controller is made up of phase inverter and high-power FET, with as being used by monolithic processor controlled electronic switch.

Described o controller is made as solenoid valve controller respectively, photoflash controller and shutter controller, and respectively by interface corresponding on the housing respectively with solenoid valve and flashlamp and shutter is movable pegs graft, so that after single-chip microcomputer is handled detection signal, respectively flashlamp and shutter are controlled by photoflash controller and shutter controller, to realize object is implemented the accurately control synchronously of flash of light and shutter, by solenoid valve controller solenoid valve is controlled, to produce accurately controlled drop, thereby realize different sizes, the shooting of the drop of friction speed is taken as the collision scene that two of continuous generation is dripped.

Described voltage stabilizer provides required 5V and 3.3V DC voltage for each several part.

Described keyboard is made of 4 microswitches, is responsible for finishing user's input.

Described display screen is a LCD display, is made of the lattice liquid crystal display screen of level conversion driver and a slice 128*64, can clearly systematic parameter and running status be shown to the user.

Described single-chip microcomputer is the STC90C58 single-chip microcomputer, finishes the coordination and the control of whole device by the firmware program of inside.

The utlity model has following advantage and effect: adopt such scheme, can be easily by infrared, laser, detected subject of probe such as microphone (sound) and surrounding environment, and send single-chip microcomputer to carry out delay process through the sensor input interface the detected signal, unlatching by the Single-chip Controlling o controller, thereby realize accurately control synchronously to flashlamp and shutter, can also control solenoid valve simultaneously, to produce accurately controlled drop, thereby realize different sizes, the shooting of the drop of friction speed is taken as the collision scene that two of continuous generation is dripped.The utility model reduces the requirement to shooting environmental, thereby improves the success ratio of taking, and it is simple and clear, workable, simple in structure to make parameter that adjustment is set, and cost is low, favorable expandability.
