Abstract
The utility model discloses an electronic screen information transmission device which relates to a technique that can transmit information via electronic screens such as a TV or various displays, etc., and can be used for information transmission between electronic screens and programmable toys, small products, teaching experiments or domestic appliances. The transmission device comprises a photoelectric signal transmitter and a photoelectric signal receiver, wherein the photoelectric signal transmitter is composed of a single chip computer (SCM) connected with a small light, and is connected with an electronic displaying screen via an RS232 communication line. The circuit of the photoelectric signal receiver is formed by connecting a photoelectric sensor, a signal processing circuit, a logic control SCM and an input-output control circuit. The utility model has the operating principle that the flickering small light on a photoelectric signal generator is shot and displayed on a TV; users point the photoelectric signal receiver to flickering small light spots on the TV screen and then can directly download a program. The utility model can also be applicable to programmable toys, small products, teaching experiments and domestic electric appliances.
Description
Technical field
The utility model relates to a kind of external transmitter that is used for the information of transmitting with television screen or display, and this transmitter is applicable to the information transmission of toy, game machine, little making, education experiment and household electrical appliance and electronic curtain.
Background technology
At present, infotech is quite flourishing, and image media electrical equipment such as televisor are extremely general, and medium all utilize screen display performance medium content.Televisor shows the content of TV station by display, all the other household electrical appliance such as video camera etc., and situation in any case all is to watch to the people, not more the utilization.In view of this, how to make televisor (comprising various displays) not only be used for display image, simultaneously can also be as a window that transmits information, and this window and toy or little making, education experiment, household electrical appliance etc. are linked to each other, give these media devices increases a brand-new function.Put it briefly, allow exactly display not only as one in general sense real interface but also can utilize its very little some area, set up one extremely simple and be a Low-cost Information output window, the routine data that photoelectric signal receiver is obtained can be applied on the Jig-saw-puzzle toy or education experiment and household electrical appliance of high intelligence, thereby expanded the mode that practical application form and information are transmitted greatly, innovation motivation of the present invention just place.
The utility model content
At the deficiencies in the prior art, the purpose of this utility model provides a kind of electronic curtain data transmission machine, screen transmission information by televisor (comprising various displays), its lampet launching procedure by glimmering in the TV programme, aim at little luminous point on the TV screen with photoelectric signal receiver and receive program and be applied in programmable Jig-saw-puzzle toy (electric intelligent toys) or aspects such as education experiment, household electrical appliance, little making, it can provide a kind of convenience, simple, control program downloaded forms that cost is minimum.
The purpose of this utility model is achieved through the following technical solutions: a kind of electronic curtain data transmission machine, this transmitter comprises photosignal transmitter and photoelectric signal receiver, the photosignal transmitter connects by the communication interface of data communication line with electronic curtain, photoelectric signal receiver is connected and composed successively by photoelectric sensor, signal processing circuit, logic control single-chip microcomputer, the logic control single-chip microcomputer is connected with input/output control circuit, its photoelectric sensor inputs to the logic control single-chip microcomputer after sending induced signal to the signal processing circuit processing.
Described photosignal transmitter portion connects lampet by a single-chip microcomputer and constitutes.
With video recorder the lampet that glimmers on the photosignal transmitter is filmed, broadcasts on TV, the little luminous point that spectators just can directly aim on the screen with photoelectric signal receiver has directly received program.
Advantage of the present utility model shows: people are directly downloaded from television screen by very simple mode.Its radiating portion can be put in the studio and not influence the normal broadcast of program, each action that program is compiled can convey to spectators by the flicker number of times and the frequency of lampet, and spectators only need use receiving trap to aim at the little luminous point that glimmers on the televisor, just can receive the program of work such as control programmable toy, household electrical appliance.The utility model can provide a kind of information transmission mode of the simplest, the minimum most convenient of cost.
Description of drawings
Fig. 1 is the circuit theory diagrams of the utility model photosignal transmitter portion.
Fig. 2 is the circuit theory diagrams of the utility model photoelectric signal receiver part.
Embodiment
A kind of electronic curtain data transmission machine, comprise photosignal transmitter and photoelectric signal receiver, as shown in Figure 1, the photosignal transmitter connects by the communication interface of data communication line with electronic curtain, and the photosignal transmitter portion connects lampet by a single-chip microcomputer and constitutes; The model of single-chip microcomputer can be 16AI 0346.As shown in Figure 2, photoelectric signal receiver is connected and composed successively by photoelectric sensor, signal processing circuit, logic control single-chip microcomputer, and the model of single-chip microcomputer can be AT90S2313, and the photoelectric sensor among the figure is a photodiode.
As other scheme of the present utility model, photoelectric sensor and signal processor can be parallel multiplex, the output of its multichannel all connects single-chip microcomputer, and single-chip microcomputer can connected storage, and photovoltaic sensing element can be photoresistance, photoelectric tube, photodiode or photoelectric cell unit.
Its circuit working principle can be understood like this: glitter by the coding to special pattern cursor on the television display, electric signal can be experienced and convert to the photoelectric sensor of receiver delicately, via signal processing circuit it is done necessary the processing, by the logic control single-chip microcomputer signal is made up again, and decoding forms corresponding control programs, by imput output circuit, can effectively control the Be Controlled object.
