Design And Realization Of Environment Monitoring Platform For Computer Room Based On Data Fusion

There are still problems in the application of wireless sensor network in the environment monitoring of computer room.Wireless sensor network nodes generally carry small capacity batteries for power supply,and once the battery power is exhausted,the nodes will be in the state of death,which severely limits the service life of WSN.Moreover,the data collected by environment monitoring in the computer room are transmitted directly without processing,which leads to unnecessary energy consumption,data redundancy and abnormality.Therefore,how to improve energy utilization rate and transfer effective data as far as possible has become the key to restrict the development of environmental monitoring in computer room.The main work of this paper includes the following three aspects:(1)Deeply studied and analyzed the basic idea and operation mechanism of SEP protocol.An improved optimal clustering algorithm based on SEP protocol is proposed.According to the cluster structure of SEP protocol,the network region was optimized according to the regional first election strategy with different competition time and residual energy factors,so as to balance the energy consumption in the region.In this region,the optimal cluster head number is proposed and the common distance factor is considered.By organically combining the single-hop and multi-hop forwarding within the cluster,the two-layer routing transmission between zone head and cluster head is realized,which effectively balances the average energy consumption of sensor nodes,thus improving the network life and robustness.The new improved algorithm is applied to MATLAB simulation environment,proving the effectiveness of the algorithm.(2)By combining the proposed routing protocol with data fusion technology,this paper introduces the corresponding data fusion algorithm in the data transmission stage to solve the problems of data redundancy and errors in the data collection of computer room environment monitoring,and proposes the multi-stage data fusion algorithm,mdf-psep,based on the p-sep protocol.This scheme combines the clustering structure of routing protocol,and adopts different data fusion algorithms at different levels of the protocol.In the process of data transmission,the data in the network are fused and processed.Through experiments,it is proved that the transmission mode in which the improved algorithm generates the optimal estimation values improves the data validity and reduces the network energy consumption.(3)Set up the environment monitoring platform in the computer room,and applied the proposed algorithm and data fusion scheme in practice.Finally,the realization process of the module of the system is described in detail,and the overall function design and implementation of the sensor node,gateway,client and server in the system are described.The computer room environment monitoring platform based on data fusion makes the environment data collection more accurate and the network energy consumption more balanced.
