◆ 液晶屏幕 使用液晶屏顯示的遙控器經(jīng)更加直觀的顯示數(shù)據(jù),或許在不久還可以使用觸 摸屏進(jìn)行遙控。 ◆ 自學(xué)能力 自學(xué)遙控器可以接收并且記下另一個(gè)遙控器代碼格式,然后可以發(fā)射這種代碼格式的代碼去控制能夠識(shí)別這種代碼的設(shè)備。下面是一些遙控技術(shù)在該科技領(lǐng)域的特殊應(yīng)用。用這種方法做成的遙控系統(tǒng)雖然并不完美,但是卻是減少了很多干擾。通常為 980 納米的波長(zhǎng)。首先,紅外遙控的遙控距離只有 30 英尺,還需要視線,也就是說(shuō)紅外信號(hào)不能穿過墻壁或者看不到的地方。就會(huì)將光脈沖轉(zhuǎn)換為 001 0010 的二進(jìn)制電信號(hào),然后將這個(gè)二進(jìn)制信號(hào)傳給微處理器。 :音量增大“命令。找出其他一些高科技含量的遙控技術(shù),例如用無(wú)線射頻技術(shù)遙控電腦。t be long before you have a single remote control to manage every electronic device in your life. 無(wú)線遙控器怎樣工作 Julia Layton 著 紅外遙控工作原理 世界上第一個(gè)無(wú)線遙控器是在一戰(zhàn)中以發(fā)射無(wú)線電波來(lái)指引德國(guó)海軍摧毀盟軍的船只。re meant to extend the operating range of the IR remote control from about 30 feet to about 100 feet (give or take) and allow the signal to perate walls and glass cabi enclosures. The remote automatically transmits both IR and RF signals for every mand. When you hook up an RFtoIR converter (sometimes included with IR/RF remotes, sometimes sold as addons) on the receiving end, it receives and converts the signal back into the infrared pulses the device can understand. Now you39。t need to input the mand codes yourself a learning remote picks up and stores the signals another remote sends out. All learning remotes are considered universal remotes because they can control more than one device. Macro mands A macro is a series of mands that you program to occur sequentially at the push of a single button. These macros can be anything you want, such as an activity mand. You can set up a macro that lets you push one button to activate, in order, everything that needs to happen for you to watch a movie or listen to a CD. (Some remotes e with activity mands preprogrammed, and others let you download macros from the Inter.) PC connectivity There are remotes that connect to your PC via the USB port so you can install programming software and download mand codes and personalized graphic icons (for remotes with LCD screens). LCD screen A remotecontrol LCD screen may simply display data, or it may be a touchscreen that receives user input. User interfaces Most remotes still utilize the simple buttonpushing method,
