Research On The Key Technologies Of Intelligent Streetlight Management And Control Based On 6LoWPAN

With the development and progress of society,the idea of ??bringing forward the wisdom of the city is also gradually implemented in the national urban planning,and intelligent street management and control system as an important infrastructure for municipal construction,is an important branch of the construction of the wisdom of the city.In this paper,intelligent street lighting management and control system for the demand,through the horizontal comparison Zigbee applied to industrial automation or intelligent home networking technology,select the universal,universal applicability,with IP addressing,low power consumption and other advantages 6LoWPAN technology.The intelligent street lamp management and control platform based on 6LoWPAN is constructed,and the following research work is carried out:Improved 6LoWPAN hierarchical routing protocol HiLow.By improving the HiLow address allocation algorithm and the path recovery strategy,the hierarchical routing protocol can support the dynamic topology and enhance the stability of the 6LoWPAN network and the reliability of the routing protocol.The simulation results show that the algorithm can complete the data forwarding Function,the nodes in the routing tree to select the candidate parent node in the routing tree to ensure that the routing tree load balancing,improve network performance and make the node survival time has also been extended.The improved HiLow routing protocol provides a better alternative solution for 6Lo WPAN routing.Design and implementation of the sensor nodes,street lights controller node and6 LoWPAN edge router composed of intelligent street light control platform of the underlying network.The streetlight controller,which is installed on each street lamp,realizes the functions of control,monitoring,sensor data acquisition and network communication.The data communication between street lamp and streetlight is realized based on 6Lo WPAN wireless ad hoc network technology.Through the street network exchange,data can be6 LoWPAN edge router,to achieve streetlight and the communication between the Internet.At the same time,intelligent street light controller can also be RFID technology,active tags from the collection,active sensor signal to achieve the function of sensor networks.
