[Abstract]:As a result of the rapid development of society, the per capita energy demand is increasing day by day, resulting in a series of urgent problems, such as the shortage of energy resources and environmental pollution, and the study of low pollution. Renewable new energy sources and their power generation technologies have attracted the attention of all countries, especially the wind-to-wind complementary power generation technology, which has become a research hotspot in various countries at present, in which the typical wind complementary street lamp lighting system has been put into use in some areas. But because the research is not deep enough, there are some problems, such as low cost performance ratio, short life span and low level of intelligent monitoring. For some small and medium-sized cities with abundant scenery and resources, a cross structure street lamp monitoring system is designed during the transition period before the street lamp lighting system uses new energy sources: on both sides of the highway, one side of the street lamp remains the same as the conventional LED street lamp. The other side is replaced by the LED street lamp with complementary scenery and adopts the network structure of ZigBee and GPRS to monitor the cross type street lamp system to realize the intelligent management of the street lamp and to improve the power supply reliability of the street lamp on the basis of energy saving. Firstly, the paper expounds the research status of wind power complementary generation technology, street lamp lighting monitoring system and the theory of ZigBee and GPRS wireless communication technology, analyzes the components and existing problems of the wind complementary LED street lamp system. The architecture of cross structure street lamp system is put forward, and the overall design of cross type landscape complementary street lamp monitoring system based on ZigBee and GPRS is carried out, including the network topology and network flow of cross structure street lamp system. The improved routing algorithm and communication protocol are combined with Cluster-Tree and AODV algorithm. Thirdly, the hardware circuit of the street lamp monitoring system is designed, including the terminal node circuit of LED street lamp with complementary scenery. Conventional LED street lamp routing node circuit and subnet gateway circuit, in which the terminal node, routing node and the core controller of the coordinator in the gateway are all selected CC2430 chip. The street lamp node circuit includes radio frequency circuit, power supply circuit, and so on. Data acquisition circuit and LED street lamp drive and control circuit. Finally, the software part of the street lamp monitoring system is designed, including the control flow of the street lamp node. The work flow of the subnet gateway and the monitoring flow of the main control center. The design of the cross wind complementary street lamp monitoring system improves the power supply reliability of the street lamp on the basis of energy saving.
