Research On Wireless Network Technology In Office Intelligent Lighting System

Most current office intelligent lighting systems using cable connected to the controller in order to realize the lamp control,networking equipment of switch and sensor need battery or power supply.The system installation requires slotted wiring,maintenance need replacement battery frequently.In this dissertation,the passive wireless office combine wireless networking technology and indoor light energy harvesting technology of intelligent lighting system,which without slot wiring installation,equipment like switches and sensors realized by energy self-sufficient,dispensing with maintenance.This dissertation mainly focuses on the wireless networking technology and the light energy collection technology of office intelligent lighting system,and implements the network equipment without power supply line and data line.This dissertation shows the overall scheme of intelligent office lighting system and designs the wireless gateway and node in the system.A kind of wireless signal transmitter is designed to collect indoor light energy and realize the passive wireless switch and sensor.The topology of the wireless network is proposed,and the process of the network establishes and nodes enter the network are proposed.At the same time,it designs the network data transmission mechanism and self-recovery mechanism,which ensures the stable transmission of network data.In the process of rapid grouping of wireless networking technology,information islands are of common occurrence,which leads to insufficient utilization of network resources.In this dissertation,a rapid detection mechanism based on virtual link technology and hand-held testing device is proposed,then the mechanism is simulated and analyzed.The analysis shows that this mechanism can search for information island effectively,and the processing is superior to the traditional search method.In this dissertation,the test software of wireless network and the analysis tool of airborne wireless packet are developed,which is used for the monitoring analysis of wireless network,at last,the packet loss rate and power consumption of the wireless network are tested.The experimental data show that the wireless network can meet the requirements of the office intelligent lighting system.
