Below in conjunction with the drawings and specific embodiments, concrete introduction is done to the present invention.
Control system of the present invention using the Set Top Box of broadcasting and TV as control objectives, because the coded format of the remote control of Set Top Box is compatible, so control objectives is extensive.
Coding due to the set-top box remote controller of broadcasting and TV adopts 32, so need to decode to set-top box remote controller remote control mode.
General infrared remote control system is all be made up of three parts: infrared remote-controlled signal reflector, infrared remote-controlled signal receiver, microcontroller and peripheral circuit thereof.
Wherein, infrared remote-controlled signal reflector is used for producing remote control code pulse.Drive infrared transmitting tube export infrared remote-controlled signal, remote control accepting header is amplified remote signal, detection, shaping, finally demodulate remote control code pulse.
Most of remote control code pulse signal is all be modulated on the square wave of 38KHZ, after Hyblid Buffer Amplifier, deliver to infrarede emitting diode, is converted into infrared signal and launches.
Coded format: data format includes guidance code, user code, numeric data code and numeric data code radix-minus-one complement, coding always accounts for 32.Data radix-minus-one complement be numeric data code anti-phase after coding, can be used for the error correction to data during coding.Attention: the user code of second segment also can be configured to the radix-minus-one complement of first paragraph user code in remote control application circuit.
Fig. 1 (a) to Fig. 1 (d) gives the transmitted waveform of set-top box remote controller.Wherein, Fig. 1 (a) is the complete waveform of launching, and Fig. 1 (b) is the guidance code waveform launched, the transmitted waveform that Fig. 1 (c) is binary zero, the transmitted waveform that Fig. 1 (d) is binary one.
From Fig. 1 (a) to Fig. 1 (d) we: no matter be 0 signal or 1 signal, their low duration is all identical, but their high level lasting time is different, can identify that the current signal received is in guidance code according to the high level lasting time of pulse, or position " 0 " or position " 1 ".
Based on this rule, with reference to Fig. 2, the decoding process of Set Top Box is as follows:
Arm processor accepts infrared waveform, obtains high level time, then several threshold values of the high level time of acquisition and setting is compared:
(1) if high level time is more than or equal to 5.0ms, then current demand signal is invalid signals, otherwise execution step (2) continues to compare;
(2) if high level time is greater than 4.0ms, then current demand signal is initial signal, otherwise execution step (3) continues to compare;
(3) if high level time is greater than 1.2ms and be less than 1.8ms, then current demand signal is 1 signal, otherwise execution step (4) continues to compare;
(4) if high level time is greater than 0.2ms and be less than 1.0ms, then current demand signal is 0 signal, otherwise is invalid signals.
The user code of Set Top Box is 16, after Set Top Box receives initial signal, can judge whether to have received 32 bit data, if receive 32 much of that, stops receiving, if do not receive enough 32, continues to receive, and by data to shifting left.
