Embodiment
A kind of remote control display screen system, is characterized in that comprising switch module, driver module, display module, main control module, remote control module, converter and communication terminal; Wherein display module is connected in driver module; Driver module is connected with Switching Power Supply; Main control module is connected with Switching Power Supply; Driver module is connected with main control module; Remote control module is connected with main control module; Converter is connected with main control module; Communication terminal is connected with converter.
A kind of remote control display screen system of the present invention, described main control module adopts STC89C58 single-chip microcomputer.The frequency of operation of described main control module is 22.1148MHz, improves frequency and makes display more stable, and the defeated outbound signal of P0 mouth, after 74HC154 decoding, produces the road wheel stream display of advancing that row gating signal sends into display screen.Single-chip microcomputer P2 mouth is connected with 8 bit shift register 74HC595.Described remote control module adopts infrared remote control module.Described infrared remote control module adopts HS0038 infrared receiving terminal.Described display module adopts LED dot matrix screen, and system display 16 row, the 64 bright white 5mm LED the arranged diode that glows is built into.Often the anode of row 64 LED is connected to line and draws, and 16 row 16 interfaces are as common anode line interface end, and convenient and row cutting model calling, realizes location and the scanning of row; Often the negative electrode of row 16 LED is connected and draws, and every 8 alignments form an interface, conveniently connects with row driver module, realizes storage and the scanning of register data, thus be built into display screen system.LED display screen has 16 row altogether, carries out decoding select amplify through TIP127 and convert high level to a slice 74HC154 to 16 row LED, thus gating line.Column scan drives the scheme adopting parallel data serial transmission, data latches 74HC595.64 row drive with 8 pieces of 74HC595 chips, and 8 pieces of 74HC595 join end to end, before the displacement output of one piece of 74HC595 be connected to next block 74HC595 and input, the serial data input of first piece of 74HC595 is connected with single-chip data output terminal.: transmitting terminal input signal is sent into infrared transmitting tube and is launched after amplifying, and at receiving end, after receiving tube receives infrared signal, amplifies process be reduced into control signal by amplifier.Press some buttons, single-chip microcomputer identifies this button, and the pulse of certain frequency launched by single-chip microcomputer to the port being connected to infrared transmitting tube simultaneously.The carrier pulse of this pulse and about 38 kHz is modulated, and then Hyblid Buffer Amplifier is carried out in modulated pulse, and electric energy conversion is luminous energy by excitation infrarede emitting diode, makes infrarede emitting diode launch the infrared ray of certain frequency.After receiving control system receives this infrared light, obtained the frequency of this infrared light by Timer/Counter in single-chip microcomputer, then this frequency is sent to CPU, by CPU, this signal is decoded, identify control signal, thus controlling functions is implemented to control circuit, complete whole distant control function.Use the remote control circuit that infrared emission, receiver are formed, receiver of remote-control sytem is by receiving and identifying infrared light, judge control operation, whole Infrared Remote-Control Sending, receiving course are come, displaying contents can be upgraded easily, change display mode, make design have more the convenience of practicality and operation control.
