Description
Technical field
Embodiments of the present invention are related to IR remote controller field, more specifically, embodiments of the present invention are related to one kind
Multi-way remote control method of reseptance.
Background technology
Remote controler, particularly IR remote controller, are widely used to the products such as projection, air-conditioning, TV, to make to allow remote control to connect
Receive it is sensitive, can use Multi-way remote control receive.Multi-way remote control is received, if multiple signals parallel connection is often led to receiving sensitivity on the contrary
Reduce;Remote signal all the way is received according to an IO, then takes multichannel I/O port resource.
The content of the invention
The purpose of the present invention is for the defects of above-mentioned background technology, there is provided a kind of single channel I/O port is sampled by AD and received
Multi-way remote control signal, saves I/O port resource.
In order to reach above-mentioned technique effect, the present invention takes following technical scheme:A kind of Multi-way remote control method of reseptance, bag
Include following steps:
The output pin of Multi-way remote control receiver, is followed by same AD thief hatch by series resistance;
Rational resistance value is set, allows Multi-way remote control receiver all to export combination and all possesses different voltage;By fixed
When sample AD magnitudes of voltage, the anti-output state for releasing current whole receivers of remote-control sytem.
Further technical solution is:Multi-way remote control receiver is specially two-way receiver of remote-control sytem, is the first remote control respectively
Receiver and the second receiver of remote-control sytem, the output pin series resistance R1 of first receiver of remote-control sytem, second remote control connect
The output pin series resistance R2 of device is received, for receiver of remote-control sytem when not receiving signal, its output is high level (Vcc), is received
Level is 0 during signal;The output of two-way receiver of remote-control sytem has 4 kinds of combinations:Only the first receiver of remote-control sytem receives;Only second remote control
Receiver receives;Two-way receives;Two-way does not receive.
Further technical solution is:The specific voltage condition of AD thief hatch is as follows:
When only the first receiver of remote-control sytem receives infrared signal, AD thief hatch voltage conditions are:High level is Vcc;It is low
Level is Vcc*R2/ (R1+R2);
When only the second receiver of remote-control sytem receives infrared signal, AD thief hatch voltage conditions are:High level is Vcc;It is low
Level is Vcc*R1/ (R1+R2);
When two-way receiver of remote-control sytem receives signal at the same time, AD thief hatch voltage conditions are:High level is Vcc;Low level
For 0.
When the equal no signal of two-way receiver of remote-control sytem:AD mouthfuls of voltages are Vcc always.
Further technical solution is:Multi-way remote control receiver is more than 3 tunnels, the resistance of each road receiver of remote-control sytem series connection takes
Value is suitable, the state of each road receiver of remote-control sytem can be parsed by AD thief hatch voltages, and then parse their received contents.
Sampled the invention discloses a kind of single channel I/O port by AD and receive Multi-way remote control signal, it includes:Receiver of remote-control sytem,
AD conversion mouth, divider resistance.Receiver of remote-control sytem, using active reception head, its effect is to receive down radio signal carrier
Come, be converted into corresponding low and high level signal, generally represent 1 with high level, low level represents 0.Multi-way remote control receiver it is defeated
Outlet passes through resistor coupled in parallel, is consequently formed a bleeder circuit;Simultaneously because receiver of remote-control sytem output pin is during idle time in height
Level, therefore pull-up power supply each other.System only needs the magnitude of voltage of this bleeder circuit of regular check, it is possible to analyzes each distant
The voltage status of receiver output is controlled, and then decodes specific remote control mode.
Compared with prior art, the present invention with following beneficial effect:
The present invention provides a kind of single channel I/O port, the method that Multi-way remote control is received by the way of AD conversion.In current IC collection
In the case that Cheng Du is very high, this method saves I/O port resource, facilitating chip encapsulation.
Brief description of the drawings
Fig. 1 shows circuit diagram according to embodiments of the present invention.
Fig. 2 is NEC infrared remote control form schematic diagrams of the embodiment of the present invention
Fig. 3 is a kind of flow chart of Multi-way remote control method of reseptance of the embodiment of the present invention.
Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to embodiments, to the present invention
It is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not used to
Limit the present invention.
Embodiment
As shown in Figure 1, the output pin of the first receiver of remote-control sytem 1, is connected, R1 resistance is 10K Europe by R1 and AD samplings;
The output pin of second receiver of remote-control sytem 2, by R2 and AD using connecting, R2 resistance is 5K Europe.The remote signal of reception is NEC
The telecontrol code of form.
For NEC infrared remote controls form as shown in Fig. 2, black portions are high level, white is low level.With reference to Fig. 3.Its
In above 9ms high level and 4.5ms low levels represent remote control seeker;Four parts such as Address and Command are below
The data of 8bit, wherein 560us high level+560us low levels represent bit0, and 560us high level+1690us low levels represent
bit1。
To ensure that two-way remote signal can be resolved out, it is necessary to analyze the first receiver of remote-control sytem 1, the second remote control reception
Device 2 individually receives signal, while receives signal and at the same time 4 kinds of situations of no signal:
1:When only the first receiver of remote-control sytem 1 receives infrared signal, AD thief hatch voltage conditions are:High level is Vcc;
Low level is Vcc*R2/ (R1+R2)=1/3Vcc;
2:When only the second receiver of remote-control sytem 2 receives infrared signal, AD thief hatch voltage conditions are:High level is Vcc;
Low level is Vcc*R2/ (R1+R2)=2/3Vcc;
3:When two receivers of remote-control sytem receive signal at the same time, AD thief hatch voltage conditions are:High level is Vcc;Low electricity
Put down as 0;
4:When two equal no signals of receiver of remote-control sytem:AD mouthfuls of voltages are Vcc always.
4 kinds of situations are it is recognised that two-way remote control reception situation can be parsed more than.
Although reference be made herein to invention has been described for explanatory embodiment of the invention, however, it is to be understood that ability
