在節能減碳潮流下,校園電費支出中佔最大比例的兩部分,分別為教室照明與空調系統。校園教室使用具固定而規律的特性,將固定的課表資料鍵入網路資料庫,配合校園中現有網路環境,利用ZigBee的閘道器來連結資料庫與所有教室ZigBee控制節點,以網路資料庫規劃的排程,配合ZigBee來管控校園教室區的照明與空調系統。在不改變學生對熱舒適度的反應下,對教室分離式空調主機作負載控制最佳化,達到節能減碳的目的。並且利用ZigBee網路來監控校園各教室的照明與空調系統的使用狀況,方便管理人員利用網路來對教室照明與空調做遠端控制,以達管控方便及節省人力的目的。
In the trend of energy saving and carbon emission reduction, the biggest parts of campus electricity bill come from classroom lighting and air-conditioning. The use of campus classroom has the feature of regularity. When we link fixed class schedules with Network database and match up with the available campus Network, and then we are able to use Gateway in ZigBee to connect the database and all the classroom ZigBee nodes. By using Network database and ZigBee to control classroom lighting and air conditioning, under the circumstances that it don’t change student’s response to thermal comfort, we can optimize the load control for the separable air-conditioning. In this way ,we can avoid the consumption of electricity at school will not exceed the contract capacity on Power rate and thus save on electricity bill and reduce the emission of carbon dioxide。The utilization of ZigBee Network to monitor the use of campus classroom lighting and air conditioning also enable the management personnel’s to remote control the classroom lighting and air conditioning.
