Description
本发明属于照明控制技术领域，尤其涉及一种教室照明智能控制系统。The invention belongs to the technical field of lighting control, and in particular relates to a classroom lighting intelligent control system.
随着国家对人才的日益重视，各类大、中专院校不断扩招，教室不断扩建，使得教室照明成为校园建设中非常重要的部分。As the country pays more and more attention to talents, various universities and colleges continue to expand enrollment, and classrooms continue to expand, making classroom lighting a very important part of campus construction.
在复杂的教室环境中，照明控制首先要考虑正常环境下的室内光照调节。实际教室的使用中，经常存在室内光照足够时，灯具不能够合理及时关灭的现象，同时还存在着使用人员离开教室后灯具未能及时关灭的现象，同时，室内人员的分布对照明系统也有极大的影响，人员的区域性的集中分布或者是个体性的分散分布，造成教室的灯具全开或灯具常开，这些现象都会造成极大的资源浪费，不符合节能环保的需求。In a complex classroom environment, lighting control must first consider indoor lighting adjustment under normal circumstances. In actual classroom use, there is often a phenomenon that the lamps cannot be turned off in a reasonable and timely manner when the indoor light is sufficient. At the same time, there is also a phenomenon that the lamps cannot be turned off in time after the users leave the classroom. At the same time, the distribution of indoor personnel affects the lighting system. It also has a great impact. The regional centralized distribution of personnel or the individual scattered distribution causes the lamps in the classroom to be fully turned on or the lamps are always on. These phenomena will cause a great waste of resources and do not meet the needs of energy conservation and environmental protection.
另一方面，还存在教室中自然光照度难以满足使用者的需求时，灯具不能及时打开的现象，对使用者的眼睛造成很大的伤害，以及，在复杂的教室环境下，教学进行的过程中经常需要人工调节照明强度，严重浪费了教学时间。On the other hand, when the natural illuminance in the classroom is difficult to meet the needs of the users, the lamps cannot be turned on in time, causing great damage to the eyes of the users, and in the complicated classroom environment, during the teaching process It is often necessary to manually adjust the lighting intensity, which seriously wastes teaching time.
