家庭自動(dòng)化無線技術(shù)可以節(jié)省能源

　　今天，大多數(shù)工程師花了大量的時(shí)間專注于生產(chǎn)節(jié)能產(chǎn)品。然而，在更大的計(jì)劃中，即使在能源效率低的家庭或辦公室使用節(jié)能產(chǎn)品也不會(huì)對整體能源消耗產(chǎn)生太大影響。家庭和樓宇自動(dòng)化是適當(dāng)集成的技術(shù)能極大地影響總能源使用。

　　直到最近，一個(gè)真正的節(jié)能住宅或建筑必須從地面設(shè)計(jì)，整合所有的布線，有線傳感器和有線控制所需的智能使用能源。多年來，這一直是阻礙市場的絆腳石，因?yàn)樗恢С址率袌觥?/p>

　　這就是低成本、可靠的無線技術(shù)發(fā)揮作用的地方。一些建筑自動(dòng)化標(biāo)準(zhǔn)正在出現(xiàn)并競相接受，承諾節(jié)約能源，并提高我們的生活方式、舒適度、安全性和健康。無線家庭和樓宇自動(dòng)化是一個(gè)必然發(fā)展的領(lǐng)域。

　　本文描述了一些新出現(xiàn)的無線家庭和樓宇自動(dòng)化標(biāo)準(zhǔn)以及用于使它們工作的設(shè)備。

　　Early attempts

　　The first attempt at wireless connectivity for home automation came from BSR， who later became X-10. These modular blocks plugged into outlets and allowed remote control and timed events to dictate when something turned on or off， as well as controlling the intensity level for dimming of incandescent bulbs.

　　By using the power lines as the signaling medium， X-10 devices did not require any new communication wires and thus called themselves wireless. Although crude by current standards， these devices were somewhat effective， though there were issues when a controller was on a different phase of the power line than the controlled device.
