At CEBIT 2016 in Hannover, Germany, Huawei released the first multi-level intelligent control lighting IoT solution, which aims to enter the intelligent lighting field with urban street lighting as the entry point. Under the concept of “Internet of Everything and Intensive Integrationâ€, ZTE Corporation also took the lead in launching the “Blue Pillar†intelligent street lamp integrated solution integrating the street lamps, charging piles, base stations and smart city information collection. . So what is the difference between their respective smart street lighting solutions and traditional street lighting solutions? Let's take a look.
Huawei: On-demand lighting, energy efficiency up to 80%
Multi-level intelligent control lighting IoT solution integrates urban lighting street lights into the IoT network and visually manages them based on GIS. Managers can clearly understand the status information of each street and every street lamp; through the application of flexible lighting strategies It can accurately control the switching status and illumination brightness of each street lamp, realizing on-demand illumination, and energy saving efficiency up to 80%.
Huawei and partner ESL (Enika Smart Light as) jointly released lighting Internet of Things solutions
1. The lighting strategy "combination boxing" comes together to ensure high efficiency and energy saving . A street light controller is installed for each street light to control the switch and dimming. Different from the industry's use of streetlight access methods such as Wi-Fi, Huawei uses IPv6-based 6LoWPAN technology, which has low power consumption, self-discovery, self-organizing network, and can be self-healing quickly, and can be better and better. Sensors and other smart devices interact. In the control of street lamps, the lighting strategy has a set of "combination boxing", which can be calculated based on the local latitude and longitude. The lighting duration of different seasons, different months and even every day can be dynamically adjusted. It can also be combined with the built-in brightness sensor. Third-party traffic, human flow sensors, etc. are linked, or intelligently adjusted according to actual weather and environmental conditions. For example, when the traffic flow is scarce late at night, the brightness of the street lights is turned down, and the lights are turned on at intervals; in the rainy weather with poor lighting conditions, the lights are turned on according to the brightness perception. The Huawei solution is based on LED street lights and uses a combination of lighting strategies. Compared with traditional street lamps such as high-pressure sodium lamps, the energy-saving efficiency is as high as 80%.
2. Visual management, street lamp online inspection, failure of the prophet . The solution uses GIS-based visual management. One person can manage thousands of street lights in multiple blocks. The number of street lights, street lights, installation location, installation time and other information in each block is clear at a glance. When the street light fails, the system will automatically alarm and send a message to notify the maintenance personnel to repair it in time. The system can also manage the life cycle of street lamps, anticipate possible failures in advance, and achieve forward-looking maintenance. This management mode has changed the situation of relying on manual regular street inspections in the past, which not only saves labor costs but also improves management efficiency.
3. Multi-level intelligent control, multi-level protection, more reliable . Traditional street lights generally use centralized control and cannot accurately control individual street lights. When the control network is faulty, it is not uncommon for many street lamps to appear "competing with the sun" during the day, resulting in waste of energy. Multi-level intelligent control is the biggest feature of Huawei's solution. It includes two levels of local intelligent control and one-level network intelligent control. Both the Agile IoT Gateway and the Street Light Controller can be equipped with lightweight agile planning components to support the localization of lighting strategies to form a two-level local intelligent decision-making mechanism. When the uplink network of the agile gateway fails, it can quickly switch to the local control strategy; when the 6LoWPAN sensor network fails, the streetlight controller can work completely offline and operate independently. Multi-level intelligent control minimizes the dependence of street lights on the control network.
4. Open up at multiple levels and draw a blueprint for a smart city . Another major feature of the Huawei solution is the adoption of a full-level open architecture. The underlying control chip can be developed based on the open source lightweight operating system Liteos. Devices from different vendors can interact better based on unified standards; agile gateways support virtualization architecture, partners can develop and install customized applications; agile controllers It provides a standard northbound interface for third-party application systems, which facilitates the expansion of various service components, and achieves all-round linkage with intelligent transportation, environmental monitoring, and urban governance, providing first-hand big data for municipal management.
ZTE: Multi-task hardware solutions and product integration
The "Blue Pillar" smart street light solution consists of ZTE's Blue Box smart charging pile, 4G iMacro new concept base station, smart control box and intelligent street light, which realizes the integration of hardware solutions and products for multiple tasks. It realizes a traditional street light pole, which is a 4G/5G base station and an electric vehicle charging pile. It can also collect comprehensive information of cities such as meteorology, environment, transportation and security. The large-screen outdoor LED screen can also provide convenience information and use. Advertising operations.
Make full use of the light pole resources and integrate into the surrounding environment, which has high concealment. It not only solves the problem of difficult site selection for 4G networks, but also builds WIFI hotspots, urban environmental monitoring, security management, and number of hot zone areas for governments and operators. Statistics provide guarantees and can provide value-added services such as targeted advertising and municipal information dissemination.
Sites have lower unit costs and higher site density . It is beneficial for operators to obtain site resources while saving land, saving electricity and saving resources. The government, operators, citizens, car owners and other parties benefited, and the operator's business field has also expanded, from communication operations to urban service integrated operations.
In response to the increasingly demanding and potential market for green energy promotion, electric vehicle charging and car networking, the “Blue Pillar†smart street lighting solution subtly integrates base stations, light poles and charging piles. Achieve one-time rapid deployment, providing a convenient solution for operating companies such as towers, not only to solve the road and community coverage problems, but also to make the information exchange of street lamps through the base station to be intelligent and integrated into the Internet of Everything.
China IOT Conference Series [The 3rd China LED Intelligent Lighting Innovation Application Summit Forum ] will invite Zigbee Alliance, WiFi, Bluetooth and 2.4G technology major supplier executives to share their market insight and latest development results, I hope you can grasp This rare opportunity to exchange, find better business opportunities, and find a higher partner.
