College Teaching Building Energy Management Control System Based On ZigBee

With the continuous construction and expansion of colleges and universities,the campus area has been continuously expanded,and the number of teaching buildings has also increased rapidly.A large number of electrical equipment for heating,ventilation and lighting in teaching buildings cannot be managed meticulously under the traditional management system,which cannot satisfy the requirement of energy-efficiency and working on-demand,which also increase management cost and leads to the waste of energy.In order to solve the above problems and achieve the goal of meticulous management,the classroom energy management system is designed based on ZigBee wireless sensor network technology.The system hardware circuit part is composed of data acquisition processing,output control and wireless data transmission modules,in which CC2530 chip is selected as the main control chip,DS18B20 module is chosen to measure temperature,human body infrared sensing module and photoresistor module to collect and brightness data of the classroom.Solid state relay and solenoid valves are adopted to control electrical equipment such as heating,ventilation and lighting.The wireless communication network composed of router node and coordinator node which implement wireless transmission of data.The control module can automatically control the opening and closing of lights,air conditioners and heating equipment of the classroom according to control strategy base on the data collected by the classroom terminal node sensors,which is meanwhile transmitted to the upper computer for monitoring.The upper computer software design is written in C# language under VS2013 programming environment The host computer has a remote control function,which can remotely control the classroom lights,air conditioners and heating solenoid valves when needed.The lower computer software is written in C language under the IAR programming environment.PCB design of the system hardware part,installation and debugging have been completed.The data acquisition and control functions of the classroom terminal nodes are tested.Classroom terminal node information monitoring and remote control functions of upper computer are tested and achieve the design requirements and objectives.
