LED Intelligent Lighting System Based On Internet Of Things

With the rapid development of the internet and semiconductor technology,people have more and more requirements on the city road lighting,which hopefully can be networked,intelligent and energy saving.Therefore,people pay much attention when intelligent lighting occurs.Compared with the traditional road lighting,there are obvious advantages of intelligent lighting,with the computer as the control platform processing the relevant information,wireless transmission of information with the use of wireless communication technology,the perfect combination of the two technologies.Remote control lighting,which not only reduces the workload of management personnel,but also can monitor,manager and maintain of the lighting conditions in rail-time.Provide and adjust the LED lamp according to the actual needs and the feedback data from the scene,which really save electricity protect the environment.Here designs a LED intelligent lighting system based on the Internet of things for the current situation of residential quarters and outdoor square street lamps.Design and develop LED intelligent lighting system based on Zig Bee technology.Firstly,the sensor module is installed on the LED street lamp to detect changes in illumination,temperature and pedestrian and vehicle activity.Then,the Zig Bee module is used for the LED street lamp to carry on the network and the data transmission,and then completes the intelligent transformation which realizes the automatic control and the energy saving for the traditional LED street lamp system.During the whole system design and development,in order to solve sensor of false positives and false negatives,the coordinator burden,data congestion and off network and so on,the stability of the system is improved by the method of soft decision,node binding,point-to-point communication,node dropping detection and re-access.Finally,through the design and development of the system and the construction and verification of the demonstration system,the wireless network of LED street lamp is realized.Open and close the switch of the automatic control system according to the environmental change of illumination.According to the status of pedestrian and vehicle,the corresponding LED street lamp can be adjusted and controlled,and the state of the LED street lamp is monitored andmanaged to achieve the purpose of saving energy and reducing consumption.
