Design And Implementation Of LED Intelligent Lighting System Based On Cloud Platform

Lighting is an integral part of human life, with the development of science and technology, the traditional lighting control mode can not meet the needs of people. In addition, the current situation is not optimistic about the lighting energy consumption Based on these, a novel technical architecture of LED intelligent lighting control system is designed, using low power LED as the light source and combining the cloud computing technology, sensing technology and wireless communication technology. Based on this architecture, three LED intelligent lighting systems are implemented in different scenarios.The implementation of the program is mainly from two parts: hardware and software. In the design process of the hardware adhere to modular methods of design standards, and package the hardware in the form of function, so the hardware system is divided into six main modules to carry out detailed design and analysis, such as controller module, ZigBee module, infrared remote control module, Ethernet module, sensor module and LED driver module. Besides, the LED driver module includes two ways: switching power supply LED driver and adjustable light LED driver. Users can choose driver module according to their own lighting conditions. The software system of the project is mainly divided into three parts: the communication module, the mobile terminal application and the implementation module. In the communication module, the relevant agreements were analyzed in detail, including NEC infrared protocol, ZigBee protocol, EDP protocol used by OneNet cloud platform and Ethernet module and HTTP protocol used by OneNet cloud platform and mobile terminal application, and according to those protocols, the data transfer function between modules is realized. In order to meet the specific requirements of the project, a mobile terminal application was developed through Studio Android, which mainly comprises three parts of the login module, user interface and network communication module. In the execution module, after receiving the data from the wireless receiver, the controller analysis the device ID and the state and finally realize the control of the state of the LED lighting device by combining with detection data of light intensity sensor.By the module function test, in order to avoid the data loss, the limit distance between the infrared or the ZigBee network nodes is 8 meters and 30 meters respectively indoor. Program tests show that the architecture has good feasibility, flexibility and applicability. Compared with the traditional intelligent lighting system, lighting system based on this architecture can not only realize large-scale network, and make full use of technical advantages of cloud platform, realize the remote monitoring function of the mobile terminal, and has the characteristic of high safety, good scalability, portability and price, etc., and has wide prospects in applications.
