[Abstract]:With the development of social economy, the city street lamp lighting system has become the window to show the charm of the city. While the street lamp lighting system brings convenience and beauty, it also meets many problems. At present, the utilization ratio of the street lamp in every big city is not high. There is a serious waste of electricity. At the same time, various industrial pollution incidents have occurred in recent years, and the haze weather phenomenon sweeping the central and eastern part of China has increased, and the existing urban lighting system has not responded to the low visibility caused by haze. Therefore, municipal departments need an intelligent street lamp control system with high efficiency and low energy consumption. In order to solve this problem, a new type of intelligent street lamp control system is designed in this paper. Through the combination of ZigBee and GPRS communication technology and multi-sensor, the intelligent control response of street lamp, the collection of environmental parameters and the saving of energy can be realized. The main contents of this paper are as follows: (1) the requirement of intelligent streetlight network is analyzed in this paper. An improved AODVjr routing protocol is designed based on the network requirements. The feasibility analysis of street lamp and the analysis of data are carried out by using OPNET simulation software. (2) an embedded system based on STM32 is designed to realize the remote control of street lamp and the collection and storage of environmental parameters. The communication and data transmission between the intelligent gateway and the monitoring center is realized by using SIM900A, and the wireless ZigBee short distance ad hoc network is constructed to ensure the smooth and timely self-repair of the street lamp network. (3) the performance of the instrument is tested. The results show that the temperature resolution is 0.1 鈩
