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 ， 因为它的波长为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的注意。

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的输出。

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硫取决于协议的被使用。

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的数据表。

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的从，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靠近接收器的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.

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.

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.

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。

地址1和16总是用来控制电视机。

Other address pairs are not always uniquely linked to a particular equipment family.

其他地址并不总是对独特的连接特定的设备的家庭。

Receiver 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.

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.
