[Abstract]:The airfield navigation light system is an important visual navigation aid equipment to ensure the aircraft safe take-off and landing. The single lamp monitoring management system can realize the automatic inspection and maintenance optimization management of the lighting system. Single lamp monitoring and management system consists of two parts: single lamp monitoring wireless sensor network and single lamp information management system. Single lamp monitoring wireless sensor network collects and transmits lamp level patrol information. The single lamp information management system is responsible for the management of information such as patrol data. How to reduce the energy consumption of network nodes and effectively manage the information collected by nodes is the key problem to be solved in the system. The compression of node monitoring information can be realized. To reduce the energy consumption of wireless sensor network nodes, In this paper, the temporal and spatial correlation of monitoring information on cluster head node and convergence node is analyzed. The feasibility of all kinds of data compression algorithms is demonstrated. On the basis of this, a data compression scheme combining differential coding and pipeline compression algorithm is proposed, which is based on the comparison of compression effects of monitoring information under different shared prefix bits. An optimized data compression strategy is developed, which determines the optimal number of shared prefix bits to be processed by the pipeline compression algorithm. The function and running time of the shared prefix extraction algorithm are tested on the hardware platform. The feasibility of the extraction method is proved. The pipeline compression algorithm is improved and simulated. The simulation results show that, The improved pipeline compression algorithm can compress the data of cluster head node and convergence node to about 60% of the initial data. According to the design method of management information system, a single lamp information management system based on C / S mode is established. The system can provide decision basis for staff to carry out maintenance according to the situation. The application of single lamp information management system can further improve the lighting. The support capability of the system and the safety of civil aviation flight lay the foundation.
