　　在樓宇自控網(wǎng)絡(luò)中采用以太網(wǎng)的優(yōu)點(diǎn)是：實(shí)現(xiàn)了從管理層(信息網(wǎng))到現(xiàn)場(chǎng)設(shè)備控制層(控制網(wǎng))的“一網(wǎng)到底”，即實(shí)現(xiàn)人們期望的通信協(xié)議的兼容和統(tǒng)一；這樣系統(tǒng)擴(kuò)展起來也比較方便；與智能建筑中其它系統(tǒng)(信息網(wǎng)通信自動(dòng)化系統(tǒng)和辦公自動(dòng)化系統(tǒng))集成起來更加容易。其缺點(diǎn)是：首先，目前開發(fā)基于以太網(wǎng)的控制系統(tǒng)產(chǎn)品的難度較大，開發(fā)費(fèi)用和成本相對(duì)還是較高，用戶可以選擇的廠商也很有限，壟斷利潤(rùn)較高，研發(fā)成本還沒有被消化，這些都導(dǎo)致產(chǎn)品價(jià)格過高。其次，以太網(wǎng)的實(shí)時(shí)性、可靠性等方面還有待進(jìn)一步完善。

　　就目前而言，不管是應(yīng)用在樓宇自控網(wǎng)絡(luò)中的基于現(xiàn)場(chǎng)總線的FCS還是以太網(wǎng)，都有論文聯(lián)盟wWw.LWl論文聯(lián)盟WWW.LWLM.COM整理m.com其優(yōu)點(diǎn)和缺點(diǎn)。隨著時(shí)間的推移和技術(shù)的進(jìn)步，它們也必將會(huì)被進(jìn)一步完善。據(jù)統(tǒng)計(jì)，我國(guó)目前有從事樓宇自動(dòng)化業(yè)務(wù)的企業(yè)3000家以上，產(chǎn)品供應(yīng)商約3000家。另外，隨著我國(guó)紹濟(jì)的快速發(fā)展和人們生活水平的不斷提高，建筑和社區(qū)的數(shù)字化建設(shè)正在興起，F(xiàn)CS和以太網(wǎng)都必將在樓宇自控領(lǐng)域中獲得更廣泛的應(yīng)用，在今后相當(dāng)長(zhǎng)的時(shí)間內(nèi)，兩者在競(jìng)爭(zhēng)的同時(shí)也將繼續(xù)并存。
