红外线遥控器控制理论
The cheapest way to remotely control a device within a visible range is via Infra-Red light.
最便宜的方法以远程控制装置内的视觉范围是通过红外光。
Almost all audio and video equipment can be controlled this way nowadays.
几乎所有的音频和视频设备可以控制这种方式现在。
Due to this wide spread use the required components are quite cheap.
由于这种广泛使用的必要组成部分是相当便宜。
Thus making it ideal for us hobbyists to use for our own projects.
从而使我们的业余爱好者的理想选择使用我们自己的项目。
This part of my knowledge base will explain the theory of operation of IR remote control, and some of the protocols that are in use in consumer electronics.
这部分的知识基础我将解释该理论的运作红外线遥控器,以及一些协议正在使用的消费电子产品。
Infra-Red Light
红外光
Infra-Red actually is normal light with a particular colour.
红外线实际上是正常的光线特别的颜色。
Us humans can't see this colour because it's wave length of 950nm is below the visible spectrum.
我们人类无法看到这个颜色因为它波长为950nm低于可见光谱。
That's one of the reasons why IR is chosen for remote control purposes, we want to use it but we're not interested in seeing it. Another reason is because IR LEDs are quite easy to make, and therefor can be very cheap.
这是原因之一是挑选红外遥控器控制的目的,我们要使用它但我们不希望看到它。另一个原因是因为红外发光二极管是非常容易,并为此可以很便宜。
Although we humans can't see the Infra-Red light emitted from a remote control doesn't mean we can't make it visible.
虽然我们人类无法看到的红外线发光从远程控制并不意味着我们不能看见它。
A video camera or digital camera can "see" the Infra-Red light as you can see in this picture.
一台摄像机或数码相机可以“看到”的红外线光正如您所看到的这张图片。
Unfortunately for us there are many more sources of Infra-Red light. The sun is the brightest source of all, but there are many others, like: light bulbs, candles, central heating system, and even our body radiates Infra-Red light.
不幸的是我们有更多的来源的红外光。太阳是最聪明的来源所有的,但也有许多其他国家,如:灯泡,蜡烛,中央供暖系统,甚至我们的身体闪耀红外光。
In fact everything that radiates heat, also radiates Infra-Red light.
事实上一切辐射热,还辐射红外光。
Therefor we have to take some precautions to guarantee that our IR message gets across to the receiver without errors.
为此我们必须采取一些预防措施以保证我们得到的红外光谱信息的接收器没有错误。
Modulation
调制
Modulation is the answer to make our signal stand out above the noise. With modulation we make the IR light source blink in a particular frequency.
调制答案是使我们的上述立场的信号噪音。调制我们的红外光源闪烁在某个特定的频率。
The IR receiver will be tuned to that frequency, so it can ignore everything else.
红外接收器将被调整到该频率,因此可以忽略一切。
You can think of this blinking as attracting the receiver's attention.
你可以认为这闪烁吸引接收机注意。
We humans also notice the blinking of yellow lights at construction sites instantly, even in brought daylight.
我们人类可以看到闪烁的黄色灯光在建筑地盘瞬间,即使在白天带来。

In the picture above you can see a modulated signal driving the IR LED of the transmitter on the left side.
上面图片中你可以看到一个调制信号驱动红外发光二极管的发射器的左边。
The detected signal is coming out of the receiver at the other side.
信号检测出来的接收机在另一边。
In serial communication we usually speak of 'marks' and 'spaces'.
串行通信中我们通常讲的'商标'和'空间' 。
The 'space' is the default signal, which is the off state in the transmitter case.
的'空间'就是默认的信号,这是关闭状态的发射情况。
No light is emitted during the 'space' state.
没有灯光的过程中排放的'空间'的状态。
During the 'mark' state of the signal the IR light is pulsed on and off at a particular frequency.
在'商标'状态信号的红外光脉冲和关闭在某个特定的频率。
Frequencies between 30kHz and 60kHz are commonly used in consumer electronics.
频率30kHz和60kHz常用的消费电子产品。
At the receiver side a 'space' is represented by a high level of the receiver's output.
在接收端一个空间,由一个高层次的接收器输出。
A 'mark' is then automatically represented by a low level.
一个标记'然后自动由一个较低的水平。
Please note that the 'marks' and 'spaces' are not the 1-s and 0-s we want to transmit.
请注意'商标'和'空间'不是1 - s和0 - S我们要转交。
The real relationship between the 'marks' and 'spaces' and the 1-s and 0-s depends on the protocol that's being used.
真正的关系'商标'和'空格'和1 - s和0硫取决于协议被使用。
More information about that can be found on the pages that describe the protocols.
更多信息可以发现对网页的描述协议。
The Transmitter
发射机
The transmitter usually is a battery powered handset.
发射机通常是电池供电的手持设备。
It should consume as little power as possible, and the IR signal should also be as strong as possible to achieve an acceptable control distance.
它应是有限的权力消费尽可能和红外信号也应该那样强劲可能达成一项可接受的控制距离。
Preferably it should be shock proof as well.
最好应该防震以及。
Many chips are designed to be used as IR transmitters.
许多芯片的目的是用作红外发射机。
The older chips were dedicated to only one of the many protocols that were invented. Nowadays very low power microcontrollers are used in IR transmitters for the simple reason that they are more flexible in their use.
旧的芯片只有一个专门的许多协议的发明。现在非常低功耗微控制器中使用的红外发射器理由很简单他们更灵活的使用。
When no button is pressed they are in a very low power sleep mode, in which hardly any current is consumed.
如果没有按下按钮他们是在一个非常低功耗的睡眠模式,在这种几乎没有任何电流消耗。
The processor wakes up to transmit the appropriate IR command only when a key is pressed.
该处理器唤醒转交适当的红外命令只有当一个键被按下。
Quartz crystals are seldom used in such handsets.
石英晶体是很少使用这种手机。
They are very fragile and tend to break easily when the handset is dropped.
他们是非常脆弱的而且往往容易打破时手机被丢弃。
Ceramic resonators are much more suitable here, because they can withstand larger physical shocks.
陶瓷谐振器更适合这里,因为他们可以承受较大的物理冲击。
The fact that they are a little less accurate is not important.
但事实是他们并不太准确一点并不重要。
The current through the LED (or LEDs) can vary from 100mA to well over 1A!
目前通过的LED (或发光二极管)可以不同百毫安远超过1A款!
In order to get an acceptable control distance the LED currents have to be as high as possible.
为了得到一个可接受的控制距离的LED电流必须尽可能地高。
A trade-off should be made between LED parameters, battery lifetime and maximum control distance.
权衡之间应作出的LED参数,电池寿命和最高的控制距离。
LED currents can be that high because the pulses driving the LEDs are very short. Average power dissipation of the LED should not exceed the maximum value though.
LED电流可高因为脉冲驱动LED的很短。平均功耗的LED不应超过最大值虽然。
You should also see to it that the maximum peek current for the LED is not exceeded.
您应该也会看到它的最大展示的LED电流不超过。
All these parameters can be found in the LED's data sheet.
所有这些参数可以在LED数据表。
A simple transistor circuit can be used to drive the LED.
一个简单的晶体管电路可用于驱动LED的。
A transistor with a suitable HFE and switching speed should be selected for this purpose.
晶体管合适HFE和开关速度应选择用于这一目的。
The resistor values can simply be calculated using Ohm's law.
该电阻值可以简单地计算欧姆定律。
Remember that the nominal voltage drop over an IR LED is approximately 1.1V.
请记住额定电压下降的红外灯约1.1V 。
The normal driver, described above, has one disadvantage.
正常的驱动程序,如上所述,有一个不利的地位。
As the battery voltage drops, the current through the LED will decrease as well.
在电池电压下降,目前的LED将通过减少以及。
This will result in a shorter control distance that can be covered.
这将导致在较短的控制距离可包括在内。
An emitter follower circuit can avoid this.
排放跟随电路可避免这种情况。
The 2 diodes in series will limit the pulses on the base of the transistor to 1.2V.
2二极管系列将限制脉冲的基础上的晶体管以1.2V电压
The base-emitter voltage of the transistor subtracts 0.6V from that, resulting in a constant amplitude of 0.6V at the emitter.
该基地发射的晶体管电压减去0.6V从,从而不断振幅0.6在排放。
This constant amplitude across a constant resistor results in current pulses of a constant magnitude.
这种不断的幅度在不断电阻电流脉冲成果的不断规模。
Calculating the current through the LED is simply applying Ohm's law again.
通过计算电流的LED只是适用欧姆定律一次。

The Receiver
接收器
Many different receiver circuits exist on the market.
许多不同的接收电路存在于市场。
The most important selection criteria are the modulation frequency used and the availability in you region.
最重要的选择标准是调制频率使用以及是否在你地区。
In the picture above you can see a typical block diagram of such an IR receiver.
上面图片中你可以看到一个典型的方框图这样一个红外接收器。
Don't be alarmed if you don't understand this part of the description, for everything is built into one single electronic component.
不要惊慌如果你不理解这部分的描述,一切是建立在一个单一的电子元件。
The received IR signal is picked up by the IR detection diode on the left side of the diagram.
收到的红外信号是上升的红外探测二极管左边的图。
This signal is amplified and limited by the first 2 stages.
这个信号是有限的扩增和第一2阶段。
The limiter acts as an AGC circuit to get a constant pulse level, regardless of the distance to the handset.
该限制器行为作为AGC电路得到不断脉冲水平,无论距离到手机上。
As you can see only the AC signal is sent to the Band Pass Filter.
正如你所看到的唯一的交流信号发送到带通滤波器。
The Band Pass Filter is tuned to the modulation frequency of the handset unit. Common frequencies range from 30kHz to 60kHz in consumer electronics.
该带通滤波器调谐的调制频率的手机部门。共同频率范围从30kHz到60kHz的消费电子产品。
The next stages are a detector, integrator and comparator.
下一阶段是一个探测器,集成和比较。
The purpose of these three blocks is to detect the presence of the modulation frequency.
的目的这三个区块是发现存在的调制频率。
If this modulation frequency is present the output of the comparator will be low.
如果这是本调制频率的输出将是比较低。
As I said before, all these blocks are integrated into a single electronic component.
正如我前面所说,所有这些模块集成到一个单一的电子元件。
There are many different manufacturers of these components on the market.
有许多不同制造商的这些组成部分在市场上。
And most devices are available in several versions each of which are tuned to a particular modulation frequency.
和大多数设备可在多种版本每个调谐其中某一调制频率。
Please note that the amplifier is set to a very high gain.
请注意放大器设定为非常高的增益。
Therefore the system tends to start oscillating very easily.
因此系统往往很容易开始振荡。
Placing a large capacitor of at least 22µF close to the receiver's power connections is mandatory to decouple the power lines.
把一个大电容至少22μF靠近接收器电源连接是强制性的以解耦的电源线。
Some data sheets recommend a resistor of 330 Ohms in series with the power supply to further decouple the power supply from the rest of the circuit.
一些数据表推荐一个330欧姆的电阻串联电源供应器以进一步解耦电源的其他电路。
There are several manufacturers of IR receivers on the market. Siemens, Vishay and Telefunken are the main suppliers here in Europe.
有几个厂家的红外接收器在市场上。西门子, Vishay的和德律风根是主要的供应商在欧洲。
Siemens has its SFH506-xx series, where xx denotes the modulation frequency of 30, 33, 36, 38, 40 or 56kHz.
西门子有其SFH506 - 20系列,其中xx是指调制频率的30 , 33 , 36 , 38 , 40或56kHz 。
Telefunken had its TFMS5xx0 and TK18xx series, where xx again indicates the modulation frequency the device is tuned to.
德律风有其TFMS5xx0和TK18xx系列,其中xx再次表明调制频率的调谐器。
It appears that these parts have now become obsolete.
看来这些地区现在已经过时了。
They are replaced by the Vishay TSOP12xx, TSOP48xx and TSOP62xx product series.
他们所取代的Vishay TSOP12xx , TSOP48xx和TSOP62xx产品系列。
Sharp, Xiamen Hualian and Japanese Electric are 3 Asian IR receiver producing companies.
夏普公司,厦门华联和日本电气3亚洲红外接收器生产公司。
Sharp has devices with very cryptic ID names, like: GP1UD26xK, GP1UD27xK and GP1UD28xK, where x is related to the modulation frequency. Hualian has it's HRMxx00 series, like the HRM3700 and HRM3800.

Japanese Electric has a series of devices that don't include the modulation frequency in the part's ID.
日本电气有一系列的设备不包括调制频率的部分编号。
The PIC-12042LM is tuned to 36.7kHz, and the PIC12043LM is tuned to 37.9kHz.
事先知情同意, 12042LM调谐36.7kHz和PIC12043LM调谐37.9kHz 。
The End?

Security is of no importance if I want to control my VCR or TV set.
安全是没有意义的如果我想控制我的录像机或电视机。
But when it comes to opening doors or cars it literally becomes a 'key' feature!
不过开门或汽车它实际上已成为'关键'的功能!
Maybe I will cover this issue later, but not for now.
也许我将涉及这一问题后,但不是现在。

Protocol
议定书

An IR message is transmitted by sending 14 pulses.
红外传输邮件发送14个脉冲。
Each pulse is 10µs long.
每个脉冲10μs长。
Three different time intervals are used to get the message across: 100µs for a logic 0, 200µs for a logic 1 and 300µs for the lead-in and lead-out.
三个不同的时间间隔是用来获取信息传递: 100μs的逻辑0 , 200μs的逻辑1和300μs的铅和铅的。
The preliminary pulse is used by the receiver to set the gain of the amplifier.
初步脉冲所使用的接收器来设置增益的放大器。
Then follows a lead-in delay of 300µs, after which the starting pulse is given.
接着一个牵头的延迟300μs ,之后开始脉冲给出。
The first bit sent is always logic 0, which has a delay duration of 100µs.
第一位发送总是逻辑0 ,其延迟时间100μs 。
This start bit can be used to calibrate the timing of the receiver.
这开始位可用来校准时间的接收器。
After the start bit follow 4 bits (MSB first) that represent the address of the message.
开始后位后续4位(最高有效位在前)代表的地址信息。
After that a total of 6 bits (MSB first) for the command are transmitted.
此后共有6位(最高有效位在前)的命令传送。
A trailing pulse should follow this command.
尾随脉冲应遵循此命令。
Finally another 300µs delay follows before the very last pulse, functioning as a lead-out.
最后再拖延如下300μs前最后脉搏,运作作为引出线。
There are a few things the receiving software can check to verify the validity of the received message.
有几件事接收软件可以检查核实所收到的邮件。
The lead-out interval should be 3 times longer than the start bit time, which has a duration of 100µs.
率先进行的间隔应该是3倍以上的开始有点时间,有时间100μs 。
Bit times should not be off by more than ±20% of the start bit length for logic 0s, or 2x the start bit length for logic 1s.
比特时代不应该关闭超过± 20 %的启动位长度为逻辑0 ,或2x开始位长度为逻辑1秒。
Don't keep waiting for pulses after 360µs after the last received pulse.
不要让等待脉冲后360μs后最后收到的脉搏。
It's very likely that the transmission is interrupted or no transmission took place at all if you have to wait longer than that.
这很可能是传输中断或没有传播发生在所有如果你不得不等待更长。
The preliminary pulse serves only AGC purposes and may be ignored by the receiving software.
初步脉冲只能自动增益控制宗旨和可能会被忽略的接收软件。
Decoding of the message should start at the Start pulse.
译码的信息应该从开始时的脉搏。
Address and Command

A control message is divided into two groups, an address of 4 bits and a command of 6 bits.
控制消息是分为两组,一个地址4位和命令的6位。
Addresses range from 1 to 16, and commands range from 1 to 64.
地址范围为1到16 ,并命令范围从1到64 。
Before the address and command are sent, 1 is subtracted from both values to get them in the range 0 to 15 and 0 to 63.
之前的地址和命令的发送, 1减去这两个值让他们在范围0到15 0到63 。
Addresses are used in pairs.
地址是用于对。
A pair of addresses is a value of 1 to 8 (0 to 7 actually), and it's inverted counter part 16 to 9 (15 to 8 actually).
一对地址是一个价值1至8 ( 0到7实际上) ,这倒计数器部分16日至9 ( 15日至8实际上) 。
The lower value address is transmitted the first time a key is pressed.
较低的价值转交地址是第一次键被按下。
The address value of all subsequent messages will be the inverted value of this first address until the key is released.
地址价值其后所有的邮件将倒置价值首先解决的关键是直到获释。
This enables the receiver to interpret repeat codes properly.
这使接收解释重复代码正确。
Messages are repeated every 130ms as long as the key remains pressed.
邮件都重复130ms只要关键仍然压。
Transmitter

It can be set to generate 3 different address pairs.
它可以设定为产生3个不同的地址对。
A fourth option is transmitting any of the 16 addresses.

接收机
The ITT protocol makes no use of a modulated carier, so the previously mentioned IR receivers won't work for this protocol.
议定书的ITT公司没有使用调制carier ,所以前面提到的IR接收器将不能正常工作本议定书。
Intermetall has created the TBA2800 for use with this protocol.
Intermetall创造了TBA2800使用本议定书。
It is a highly senisive IR detection circuit and should be shielded completely inside a metal box that is connected to ground, leaving only a small hole just in front of the IR diode.
这是一个高度senisive红外检测电路并应在一个完全屏蔽金属盒连接到地面,只留下一个小洞前面红外二极管。

There is actually not much more to be told about this IC.
其实不是更被告知这个集成电路。
Just connect it as shown in the diagram as shown above, and it should work.
只要将它连接所显示的图如上所示,它应该工作。
You can chose between a normal high going output, and an inverted low going output.
您可以选择正常高之间去输出,去倒低产出。
It depends on the rest of your circuitry which one you should use.
这取决于其他的电路你应该使用。
In case of excessive interference you could reduce the sensitivity a little by grounding pin 6 via a 10k resistor.
如果在过度干预可以减少一些敏感性的接地引脚6通过的10K电阻。

NEC Protocol
NEC公司议定书
To my knowledge the protocol I describe here was developed by NEC.
据我所知第一议定书说明这里是由NEC公司。
I've seen very similar protocol descriptions on the internet, and there the protocol is called Japanese Format.
已经看到非常相似的协议说明在互联网上,有所谓的协议是日本格式。

The total transmission time is constant because every bit is repeated with its inverted length.
总传输时间是永恒的因为每个位重复其倒长度。
If you're not interested in this reliability you can ignore the inverted values, or you can expand the Address and Command to 16 bits each!
如果你不感兴趣的可靠性可以忽略倒值,或者您也可以扩大地址和命令以16位每个!
A command is transmitted only once, even when the key on the remote control remains pressed.
命令传递只有一次,即使在关键的遥控器上仍然压。
Every 110ms a repeat code is transmitted for as long as the key remains down.
每110ms重复代码转交只要关键仍然下跌。
This repeat code is simply a 9ms AGC pulse followed by a 2.25ms space and a 560µs burst.

The first pulse is called the pre-pulse, and is made up of a 500µs burst followed by a 2.5ms pause, giving a total of 3 bit times.
第一个被称为脉冲预脉冲,并是由一个500μs爆裂之后2.5ms暂停,使共有3位次。
Then the Start bit is transmitted, which is always a logic "1".
然后开始位传播,这始终是一个逻辑“ 1 ” 。
This pulse can be used to calibrate the bit time on the receiver side, because the burst time is exactly half a bit time.
此脉冲可用于校准位时的接收方,因为突发的时间正是50位的时间。
The next 8 bits represent the IR command, which is sent with LSB first.
在未来8位代表红外命令,这是一起发送LSB的第一。
The command is followed by a 4 bit device address.
该命令之后4位器件地址。
Finally a 4 bit subcode is transmitted, which can be seen as an extension to the address bits.
最后4位子传播,它可以被看作是一个扩展的地址位。
A message consists of a 3ms pre-pulse and 17 bits of 1ms each. This adds up to a total of 20ms per message.
一个消息由一个3ms预脉冲和第17位1ms每个。这增加了总的20ms每封邮件。
Every time a key is pressed on the remote control a start message is transmitted containing a command of $FE and address/subcode of $FF.
每次键被按下遥控器上的一个开端信息传播含有命令为FE和地址/子法国法郎美元。

停止信息也使用命令$ FE和地址/子$法郎。
Every sequence can be treated as one single sequence at the receivers end because of the start and stop messages.
每个序列可以被视为一个单一的顺序在接收结束因为开始和结束的信息。
Accidental key bounces are effectively eliminated by this procedure.
意外反弹的关键是有效地消除了这个程序。
The receiver may decide to honour the repeated messages or not.
该接收机可以决定履行或不重复的邮件。
Eg cursor movements may repeat for as long as the key is pressed.
例如光标移动可重复的只要键被按下。
Numerical inputs better don't allow auto repeat.

Sometimes a message may appear to be shorter because the first half of the start bit S1 remains idle.
有时邮件可能会更短因为今年上半年一开始有点仍然闲置。
And if the last bit of the message is a logic "0" the last half bit of the message is idle too.
如果最后一点的信息是一个逻辑“ 0 ”后半叶位的邮件闲置太多。

As long as a key remains down the message will be repeated every 114ms.
只要一个关键仍是下降的消息将反复每114ms 。
The toggle bit will retain the same logical level during all of these repeated messages.
位的切换将保留相同的逻辑水平在所有这些重复的邮件。
It is up to the receiver software to interpret this auto repeat feature.
它是由接收器软件来解释这种自动重复功能。

PS: I had rather a big error on this page for quite some time now.
答:有一个大错误而在此网页上的相当一段时间。
For some mysterious reason the LSB and MSB of the address and command were reversed.
一些神秘的原因了LSB和最高有效位的地址和命令被扭转。
I can recall correcting this error before, but somehow an old version of the description must have sneeked its way to the internet again.
我记得前纠正这个错误,但不知过旧版本的描述必须sneeked方式到Internet了。
Pre-defined Commands
预先定义的命令
Philips has created a beautiful list of "standardised" commands.
飞利浦已经建立了一个美丽的名单“标准化”的命令。
This ensures the compatibility between devices from the same brand.
这确保了设备之间的兼容性来自同一品牌。
A very nice feature, often to be missed with other brands, is the fact that most devices are available twice in the table allowing you to have 2 VCRs stacked on top of each other without having trouble addressing only one of them with your remote control.
一个非常棒的功能,往往错过与其他品牌的事实是大部分器件都采用两次表让您有2录像机堆叠顶端对方而不必麻烦处理只是其中之一与您的远程控制。
I can only show a limited list of standard commands, for this list is about all I know right now.

Other Protocols
其他协议
Many other protocols exist on the market.
许多其他协议的存在在市场上。
Most often it is impossible to find out who has invented the protocol.
最常见的是不可能知道谁发明了该议定书。
If I stumble upon one of these obscure protocols I will try to decipher it as far as I can and show it on this page.
如果我失败后其中的一个模糊的协议我将试图破解它我可以并显示在此网页上。

I realise that a few big brands are still missing in my descriptions, like Philips RC6, RCMM and B&O.
我知道一些大品牌仍然失踪在我的描述,如飞利浦RC6 , RCMM和B &
Lack of information and lack of time are the main reasons why I haven't added these protocols to my knowledge base yet.
缺乏有关的资料和时间是主要的原因我没有说这些协议对我国的知识基础还没有。
