Mesh網(wǎng)絡(luò)有助于節(jié)約能源通過智能LED在家居照明控制

　　節(jié)能可以通過切換到LED照明在家里是眾所周知的。它已被廣泛記錄，低功耗，高效率的LED燈具可以降低功耗超過80%時(shí)相比，傳統(tǒng)的來源，如鹵素和白熾燈。不太好理解的是，智能照明控制可以刮掉更多的電費(fèi)賬單。智能控制功能，通過傳感器和無線網(wǎng)絡(luò)，包括自動(dòng)調(diào)光和關(guān)閉燈在無人的房間。

　　智能照明控制的市場，越來越多地被安裝作為家庭自動(dòng)化系統(tǒng)的一部分，被認(rèn)為是一個(gè)巨大的機(jī)會(huì)，在更廣泛的物聯(lián)網(wǎng)（物聯(lián)網(wǎng)）運(yùn)動(dòng)。然而，市場增長的關(guān)鍵是靈活和靈活的配置和安裝，以及成本低，投資回報(bào)快。

　　本文將考慮一些適用于國內(nèi)應(yīng)用的控制策略和無線網(wǎng)絡(luò)協(xié)議，專注于新的替代方案，建立ZigBee光鏈路。這些包括專有的協(xié)議，如線程和csrmesh技術(shù)。

　　ZigBee benefits

　　For some years， ZigBee Light Link has been regarded as the protocol of choice for smart lighting in the home， and has begun to amass a sizeable installed base. ZigBee has a number of advantages over alternative network strategies for home automation. It is established， proven， well supported and dedicated to low power sensing and control applications that demand low latency. Importantly， it is designed to support a mesh network topology， allowing alternative routes between controllers and nodes. This is essential for a flexible and scalable system， such as domestic lighting， that requires centralized， automatic， and programmable controls， as well as remote and manual ‘point’ controls.
