Research Of Data Transmission In Building Energy Consumption Monitoring System

Building energy consumption monitoring system is an integrated platform withdata acquisition, data transmission, data monitoring, energy management, energyconsumption publicity and statistical analysis. It achieve the monitoring of energyconsumption resource data such as water, electricity, gas, heating and refrigerationequipment within the building and environmental information such as indoor andoutdoor temperature, humidity, CO2concentration by network technology.Detected from the data can be used to optimize computing and energy-savingcontrol of the related energy consumption equipment in order to achieve thepurpose of energy consumption statistics, energy audit and building energyefficiency.This project is relying on research projects in Guangdong Province. Build awireless monitoring network to real-time transfer monitoring data to the systemmonitoring and management center. Wireless data transmission network is thevector of the data transmission in system, its performance will directly determinethe overall system performance. This paper analyzes problem such as datatransmission interference, load balancing face to wireless monitoring network inthe building environment. Ease the load pressure of a single sink node by deployingmore than one sink node in Monitoring network. We proposed a multi-sink nodemessage scheduling mechanism based on message urgency and dynamic loadbalancing strategy (DRBSLB) based on the proportion for multiple sink nodeenergy consumption imbalance. In order to ensure the reliability of dynamic loadbalancing strategy based on the ratio, we introduced automatic learning machines tomake the strategy has a self-learning function.Verification by NS2simulation tool, message deadline to meet the rate can beincreased by nearly10%, if multi-sink node message scheduling mechanism basedon message urgency used in some of the existing routing protocols. The networknode death time extend more than10times by using DRBSLB protocol. It balancedload, improve the reliability of data transmission, extend the network lifetime andhas great significance to improve the performance of building energy consumptionmonitoring system.
