Synthetic Parameter Testing System for Facilities Environment Based on Internet of Things

According to the need of facilities environment monitoring,a synthetic parameter testing system for facilities environment based on Internet of Things was designed and developed. This system could real-time monitor all environment parameters and long-distance observation and processing of the data could be achieved through GPRS and Internet. The design scheme of this system,techniques of Internet of Things,including wireless sensor network technology based on ZigBee,GPRS and sensor technology,were described in this paper. The principle of LEACH routing protocol was introduced briefly on the basis of wireless sensor networks node. The system adopted adaptive weighted fusion algorithm to fuse collected data and got more reasonable results. It realized real-time monitoring of facilities environment,wireless transmission of data and search of all environment parameter reports. Experiments showed that the system had stable performance,low power consumption,fast transmission rate,long transmission distance,and each indicator had reached the design requirement,which could better meet the requirement of facilities environment monitoring.
