1) Smart lighting can adopt a unified platform architecture and a discrete (vertical) platform architecture or a mixed architecture.
2) At this stage, the construction of smart lighting basically adopts a separate platform architecture. Based on resource conservation and high efficiency, taking into account industry policies and data control, a hybrid architecture can be used for pilot projects in the near future, and useful explorations for building a unified platform architecture in the future
3) The intelligent lighting unified IoT management platform can solve common problems for developers in application development such as multi-protocol adaptation, massive connection, data storage, device management, rule engine, event alarm, resource management, etc., shorten the application development cycle and reduce the application The development cost promotes the innovation and upgrading of traditional enterprise applications.
In the tide of smart city construction, the Internet of Things, big data, cloud computing and other technologies are used to build urban smart lighting, solve the existing shortcomings and problems of urban public lighting, promote the improvement of urban public lighting management, and promote energy saving and emission reduction; at the same time, use street lamp pole Resource advantages, integrating multiple technologies, realizing the comprehensive utilization of light poles, improving the level of intelligence of urban infrastructure, and laying a solid foundation for a smart city that truly realizes the integration of information resource sharing, has become an important part of smart city construction. Based on the architectural concept of the construction of a new smart city, the intelligent lighting platform architecture is proposed.
(1) Field equipment layer:
Provide a series of monitoring and management equipment required for lighting management, including single light controllers, gateways (centralized controllers), smart street lights, multi-function poles, etc.
(2) Network layer:
The network layer provides the function of network connection for intelligent lighting. Of course, single lamp control and sensors on the light pole can also provide local short-distance communication capabilities, such as RF or PLC communication, through the Guangcheng network on the gateway device (centralized controller) Communication capability (3/4G/fiber light) for remote connection.
(3) Platform layer:
The unified IoT platform realizes equipment access authentication, flexible adaptation of various terminals, and processing of massive equipment management data. The platform supports the access of different terminal types, shields different terminal interfaces and network differences for the service platform, and provides service capability opening to the service platform.
(4) Intelligent lighting business service layer:
Realize various application functions of the system, such as lighting control subsystem, multifunctional street light pole subsystem, operation and maintenance management subsystem and other subsystem modules.
Intelligent lighting construction mode
Discrete (vertical) architecture is adopted at this stage
At this stage, smart lighting is mostly built in a discrete (vertical) mode. The lighting management department builds its own management and service platform. If it needs to be connected to the smart city management system, data exchange and sharing will be carried out through API.
Pilot hybrid architecture in the near future
The hybrid mode can be adopted in the near future. As the connotation of intelligent lighting continues to expand, it not only includes the control of lighting business, but also includes sensing devices integrated on lamps or mounted light poles, especially the use of NB-1oT access methods. The advantages of a unified IoT platform are becoming more apparent. However, other equipment mounted on the multi-function pole, such as camera equipment, information release equipment, due to industry policies and data control lights, the related services of these equipment still adopt the vertical mode of discrete self-built and self-managed.
In the future, it will inevitably move towards a unified platform architecture
In the future, smart lighting will cover the comprehensive services of smart cities supported on multi-function poles. It is necessary to conduct unified access management for smart city services, and to open up data management and sharing. The use of a unified platform construction model is an inevitable choice.
Unified IoT platform: Operator's IoT platform
The operator’s Internet of Things platform is an open platform and ecological environment based on Internet of Things technology and industrial characteristics. By adapting to various network environments and protocol types, it supports the rapid access of various sensors and smart hardware and big data services. Provide a wealth of APT and application templates to support the development of various industry applications and smart hardware, which can effectively reduce the cost of IoT application development and deployment, and meet the requirements of device connection, protocol adaptation, data storage, data security, and big data analysis in the IoT field And other platform-level service requirements.
The platform solves common problems in application development such as multi-protocol adaptation, mass connection, data storage, device management, rule engine, event alarm, and resource management for developers, shortens the application development cycle, reduces application development costs, and promotes traditional enterprise application innovation upgrade.
When using smart lighting terminal controllers (such as single lamp controllers, sensor lights) that support narrowband Internet of Things (NB-1oT), the lighting terminal controller needs to be connected to the NB-1oT connection due to the need to manage and optimize the On the platform, the lighting terminal controller communicates with the central management system (lighting management system) through the Internet of Things platform.
The communication interface between the terminal controller based on NB-1oT technology and the Internet of Things platform, which is connected to the Internet of Things management platforms of different operators. The interface between the IoT platform and the central management system/lighting management system.
The terminal controller and the Internet of Things platform communicate through data messages, which are called messages. According to different requesters of the message, it can be externally called command message and event message. The command message is a message that the platform actively sends to the terminal. After the terminal receives the command message and executes it, it sends a command response to the platform. Command messages mainly include switch lights, dimming control, configuration operations, etc.
An event message is a message that the terminal actively reports to the platform, and the platform sends an event response to the terminal after receiving the message. Event messages mainly include collected lamp data, fault alarms, etc. Since the IoT platforms used by various operators are different, specific explanations are made for different operator platforms.
