家庭自動化無線技術可以節省能源

　　今天，大多數工程師花了大量的時間專注于生產節能產品。然而，在更大的計劃中，即使在能源效率低的家庭或辦公室使用節能產品也不會對整體能源消耗產生太大影響。家庭和樓宇自動化是適當集成的技術能極大地影響總能源使用。

　　直到最近，一個真正的節能住宅或建筑必須從地面設計，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，因為它不支持翻新市場。

　　這就是低成本、可靠的無線技術發揮作用的地方。一些建筑自動化標準正在出現并競相接受，承諾節約能源，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化是一個必然發展的領域。

　　本文描述了一些新出現的無線家庭和樓宇自動化標準以及用于使它們工作的設備。

　　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.
