[Abstract]:At present, most of the lighting equipments in the classrooms of colleges and universities in our country adopt the mode of independent management by the students or the management by the special personnel. It often appears the waste phenomenon such as long light during the day, no one turning on the light, and all the lights of one person being turned on. In response to the call of the country to promote energy conservation and emission reduction, it is of great value to study and realize the lighting energy-saving control system of university classrooms. Aiming at the serious problem of lighting energy waste in university classroom, this paper designs and implements a kind of lighting energy saving control system for university classroom. The system includes several classroom control units, campus network communication system and control center. The classroom control unit is composed of multi-class terminal nodes and unit controllers. The terminal nodes transmit the collected data to the unit controller through 2.4G wireless radio frequency communication. The unit controller transmits the instruction to the terminal node after the analysis and processing to perform the action of the switch lamp. The communication between the classroom unit controller and the control center depends on the school local area network. The communication between the bus data signal and the classroom unit controller signal is realized by using the wired bus distribution mode, which is stable and reliable and avoids the trouble of rewiring. The control center realizes the state monitoring, real-time control and information management of each classroom through visual interface. The method of sub-area control is adopted to overcome the problem of turning on more than one lamp when the students' seats are scattered, and the multi-mode control strategy is adopted to further meet the multi-purpose needs of the classroom and to make the system run more flexibly and humanized. The threshold of number is introduced to control the number of switches according to the use of classroom and the number of people. The opening and closing upper limit values of light intensity are introduced to effectively avoid the system disturbance of frequent switching lights caused by light intensity greater than the lower limit when the light is insufficient to turn on the light. The hardware part of this system mainly designs the classroom control unit which consists of all kinds of terminal nodes and classroom unit controller. The whole system has the advantages of low power consumption, low cost, simple operation and strong practicability.
