If according to user's control, from remote controller transmission infrared signal, just be input to the infrared ray acceptance division 12 that image display 10 1 sides possess, infrared signal is converted to the digital signal pulse.
Afterwards, be input to the microprocessor 11 of image display 10, the relevant exercises of image displays such as ON/OFF of the channel up/down of control customer requirements, volume control, power supply.
Such remote controller makes the user carrying out the button input more at a distance, not control image display with this directly near image display, and therefore, this has brought convenience to the user.
But image display is dispersed in many places when being provided with, such as, in places such as the exhibition of image display, sale agent shop, public places, has following inconvenience, be each image display of control, should move identical control action near each image display that disperses to be provided with.
Summary of the invention
The present invention is for solving above-mentioned variety of problems, and its purpose is, such equipment is provided, and promptly by once control, can control the remote control equipment of an above image display that disperses to be arranged on many places.
Remote control equipment of the present invention is characterised in that by following part and constitutes: receive the infrared signal of remote controller transmission, with the infrared ray acceptance division of digital signal pulse output; According to the output of above-mentioned infrared ray acceptance division, the microprocessor of control image display; The signal of above-mentioned infrared ray acceptance division output is transferred to the transhipment department of above-mentioned microprocessor and external image display unit.
In addition, above-mentioned transhipment department is characterised in that it possesses input terminal and lead-out terminal, by above-mentioned microprocessor and above-mentioned lead-out terminal, makes the signal that receives by above-mentioned input terminal be transferred to outside image display.
Remote control equipment of the present invention has such advantage, in the time of promptly by display device of remote controller control, also can control a plurality of image displays that connect therewith.

Embodiment
Below with reference to accompanying drawings remote control equipment of the present invention is elaborated.
Fig. 2 is the figure of explanation remote control equipment of the present invention.
Remote control equipment of the present invention comprises following part: receive the infrared signal of remote controller transmission, the infrared ray acceptance division 20 of output digital signal pulse; According to the signal of the output of above-mentioned infrared ray acceptance division 20, the microprocessor 22 of control image display; The signal of above-mentioned infrared ray acceptance division 20 outputs is transferred to the transhipment department 21 of above-mentioned microprocessor 22 and external image display unit.
It is as follows to describe transhipment department 21 in detail.The output of above-mentioned infrared ray acceptance division 20 is the base stage of resistance R 6 with the transistor Q3 that is connected in series, between the base stage of resistance R 3 connection transistor Q3, the emitter.
In addition, transistor Q3 connects the 5V power supply by emitter, and collector electrode connects the positive pole of diode D4.
Here, the negative pole of diode D4 is connected with the resistance R of ground connection 4, and connects with resistance R 5, and No. 2 PIN of the negative pole of the voltage stabilizing didoe D3 of anodal and ground connection and the input terminal 211 of No. 1 PIN terminal ground connection are connected.
No. 3 PIN of above-mentioned input terminal 211 are connected with No. 3 PIN of the lead-out terminal 212 of No. 1 PIN ground connection, connect by resistance R 8 between No. 2 and No. 3 PIN, No. 3 PIN is connected with the negative pole of the voltage stabilizing didoe D2 of plus earth, connects the base stage of the transistor Q1 of grounded emitter by resistance R 7.
The collector electrode of transistor Q1 connects the 5V power supply by resistance R 1, is connected with the base stage of the transistor Q2 of ground connection by resistance R 2 by emitter then, and the collector electrode of transistor Q2 is connected with the 5V power supply, and emitter is connected with the input of microprocessor 22.
More than the remote control equipment of the present invention with transhipment department 21 of Gou Chenging is when the image display single movement, if import infrared signals to infrared ray acceptance division 20 from remote controller, infrared ray acceptance division 20 is just with the output of digital signal pulse signal, and the collector electrode output of transistor Q3 oppositely increases amplitude signal.
In addition, by the 2-3 PIN and the resistance R 7 of diode D4 and input terminal 211, and, oppositely increase amplitude through transistor Q1.Also be input to microprocessor 22 at the collector electrode of the transistor Q1 emitter by transistor Q2, infrared signal is transferred to microprocessor 22, makes image display controlled.
Simultaneously, as shown in Figure 3, when being connected a plurality of image display by input terminal with lead-out terminal, the infrared signal of remote controller 30 transmission is connected with No. 3 PIN with No. 2 PIN of image display I 40 input terminals 41, and cuts off No. 2 PIN and No. 3 PIN of lead-out terminal 42.
At this moment, infrared signal is connected with microprocessor by transistor Q3 → Q1 → Q2, and therefore, image display I 40 carries out regular event because of infrared signal.
In addition, the input terminal 51 of image display II 50 is by No. 3 PIN and the ground wire GND received signal of image display I 40 lead-out terminals 42, also be input to microprocessor by transistor Q1, Q2, image display II 50 makes action with the signal of image display I 40.
At this moment, No. 2 PIN and No. 3 PIN of the input terminal 51 of image display II 50 are cut off, and therefore the remote control of control itself is impossible, can only control with the output signal of image display I 40.
In addition, be example with the input terminal 61 of image display III 60, from the lead-out terminal 52 received signals input of image display II 50, make action, when being connected, equally by lead-out terminal 62 transmission signals with other image display.
Therefore, remote control equipment of the present invention is operated the image display of central controlling chamber by remote controller, can control a plurality of image displays that connect therewith simultaneously.
