Research On Large Public Building Energy Consumption Data Wireless Remote Monitoring And Energy-saving Management Systems

Large-scale public buildings is usually referred to as monomer building area more than 2 million square meters in the office, using central air conditioning, business, tourism, science-education-culture-health, communication and transportation hub and other public buildings. According to the worldwide literature, the proportion of cities'and towns' building area is less than 4%, but energy consumption of building energy consumption has accounted for as to the above 20%. But unfortunately, because of the energy consumption level place is restricted, some local large-scale public buildings energy consumption data statistic inaccurately, and management oversight,public building energy waste is serious and energy-saving task is severe.Therefore, based on the analysis of several key communication technology, using ZigBee and GPRS network technology build large-scale public buildings energy consumption data wireless transfer measurement network system of building energy consumption,to accurately subentry measure the Building energy consumption of large-scale public buildings,and remote the energy data transmission to the superior management center,management personnel to energy consumption by configuration software real-time data monitoring and management. This paper mainly through research on ZigBee technical characteristics and agreement buld a energy data acquisition network based on ZigBee-Mesh network to subentry measurement the buliding's energy consumption;Designed the the software and hardware for the all function ZigBee network equipment(FFD),and use the low power consumption ATmega128 single-chip microcomputer as the master chip,with 2.4 GHz IEEE 802.15.4 standard low power consumption low voltage CC2420 chip as RF modules acquisition node equipments, adopts the ICCV7 V7.22 compiler for program compiles, through the AVR Studio 4.0 as the simulation software for the program.Finished the design on the energy consumption data wireless remote monitoring system which is based on the configuration software WebAccess with B/S network architecture,use this system as a platform for an energy management of building energy consumption, and the system takes Access database as the data storage. Finally, this paper completed the research on energy consumption of large public building wireless remote monitoring and energy management system.This paper provided a good foundation by research on energy consumption data subentry measurement and wireless acquisition network for the large-scale public building enetgy consumption data with networked, informationized, transparencily. Completed the design of energy saving and energy monitoring system as a practical technology of large-scale public buildings for energy saving transformation and energy audit,accomplished the goals in large-scale public buildings energy conservation.
