[Abstract]:With the development of urbanization in our country, the streetlight lighting system in cities is expanding. However, due to the bad weather conditions, there are problems such as power outage, insufficient power supply and so on. At the same time, electricity is saved. Increasing the utilization rate of streetlight controllers is an urgent problem for the urban streetlight lighting system. At present, the energy efficiency of street lamps in major cities is generally low, and the electricity consumption of street lamps is high, which increases the economic burden of the management and use units. The traditional street lamp controller has the problems of low intelligence, poor communication stability, inconvenient management and control, uneven distribution of road illumination. The wireless intelligent street lamp system designed in this paper adopts ZigBee wireless ad hoc network technology, which can realize the intelligent, information and high reliability of the street lamp energy saving control system. The system consists of three parts: upper computer system management software, wireless street lamp gateway and wireless street lamp controller. As ZigBee network coordinator, wireless street lamp gateway can be placed in the monitor room. On the one hand, it is responsible for the establishment and configuration of the ZigBee network, on the other hand, it connects with the host computer through Ethernet, feedback the network status and receives the control instructions of the host computer in real time. As the ZigBee network router, the wireless street lamp controller is placed inside the lamp pole. It can monitor the voltage, current, power and other parameters of the lighting circuit, and control the intelligent turn on and off of the street lamp. In ZigBee network, its function is to allow other devices to join the network and multi-hop route maintenance. Firstly, this paper introduces the research background, research status, purpose and significance, then analyzes the device types of ZigBee technical standard ZigBee network, and introduces the composition of ZigBee protocol layer in detail, including physical layer, medium access control layer. Network layer and application layer, then the overall design of wireless streetlight intelligent system is carried out, and the network topology, routing protocol and so on are studied. The system adopts the routing protocol which combines Cluser-Tree algorithm and AODVjr algorithm. The simulation analysis on NS2 platform shows that the redesigned intelligent street lamp routing protocol outperforms the former two. Then, the ZigBee RF module based on CC2530 is designed, and the schematic diagram and the matters needing attention in the PCB design are given. The software development of ZigBee protocol stack is carried out, and the various modules and operation mechanism of Z-Stack protocol stack are studied, the startup flow of ZigBee module is designed, and the function development of API interface is realized. Finally, the system installation and test are carried out in Weinan, Shaanxi Province. A total of 93 controllers are installed, including 1 wireless street lamp gateway and 92 wireless street lamp controllers. The actual operation results show that the system is running well and has high popularization value.
