根据季节性的室外光线变化及是否存在阴雨天气的影响，设定不同的系统上电时间，系统上电后，按上图3的流程实施教室的节能用电设置。由于天气的变化对光线的影响比较明显，除上述自动控制外，还应能够结合手动的调节。另外，新的用电设备的加入等特殊情况的用电事先预留控制端口，方便加入整体控制。
教室用电控制的所有节电均为终端节点，通过ZigBee将信号无线传输到各个教室的协调器节点，由协调器节电将信息通过RS232总线或GPRS方式传送到控制中心，由控制中心做出相关响应信息，经由协调器节点，到达各个终端节点，选择灯的亮、灭及亮度，选择相应的节能用电模式。
Based on the seasonal changes in outdoor light and the effect of rainy weather, it sets a different system of power-on time. After the systerm is power-on, according to the process of the Figure 3, it sets to implement energy-saving classroom. As the weather changing obviously impact on the light, in addition to the above-mentioned automatic control, it should also be combined with manual adjustment. Moreover, the addition of new electrical equipment and other special situations electricity reserve control port in advance to facilitate the accession to the overall control.
Energy saving control of the classroom are terminal nodes. The wireless signal through ZigBee transmit to the coordinator node in each classroom. The coordinator node sends the information through the RS232 bus or GPRS to the control center. Relevant responsing information, which is made by the control center , through the coordinator node to reach each terminal node, select the lights on, off and brightness, and select the appropriate energy saving pattern.
According to the change of seasonal and whether there are outdoor light, the rainy weather effects on different systems, system electric power according to the above three after the implementation of the electricity energy flow. Due to the change of weather effects of light, in addition to the obvious automatic control, still should be able to manually adjust the combination. In addition, the new electric equipment to the power of the special circumstances, such prior obligate control ports, convenient to join the whole control.
All of the power control for terminal node, electricity ZigBee through wireless transmission to the signal of the tuner node, the coordinator electricity-saving information through RS232 bus or GPRS to control center, the way to control center by relevant information via coordinator, response to each node, the choice of the lamp, end nodes, bright brightness, and select the energy saving electricity mode.
