A IOT of "strategic highland" is intelligent street lamp?

Recent intelligent lighting industry events, than HUAWEI recently in the world's largest ICT Technology Exhibition CeBIT 2016 released the first multi-level intelligent lighting control networking solutions. HUAWEI in the city street lighting in the industry application of the entrance, entered the field of smart lighting. Coincidentally, ZTE also announced the "BluePillar" program as an important landing lights the wisdom of its smart city strategy. In addition, CISCO and CREE reached a strategic cooperation in the city of intelligent lighting, both with their own lighting technology and Ethernet technology, to jointly promote the smart lighting market. Several industry heavyweights a movement stirred the intelligent lighting in a pond, and they are almost the same, no choice for intelligent lighting intelligent Home Furnishing hot point, but intelligent street lighting in the wisdom of the city on the first layout. Does this mean that things of the wind changed, intelligent lighting in the family temporarily dead, or the city of intelligent lighting market, technology is already mature? The status of intelligent street lighting in the end how? Energy saving lamp is still intelligent killer in intelligent path of city street lamp, energy saving features very attractive. The energy consumption of city street huge really annoying, such as street lighting power consumption per year in London is as high as about 56000000 degrees! Intelligent lighting scheme of HUAWEI this come up with the killer, claiming for HUAWEI's solution than originally about saving 80%. At first glance, intelligent lighting scheme energy-saving effect of HUAWEI is indeed astonishing, but for the industry people, the saving of 80% is not so magical. Because there is a traditional high pressure sodium lamp 50%-60% (power 400W) replaced with more energy-efficient LED lighting (power 150W) debuff brought. However, apart from the changing light source does not talk, indeed in the intelligent lighting management optimization system for city street lamp electricity saving out of a force. First, intelligent lighting system will calculate the time of sunrise and sunset on local longitude, in different seasons and different months or even one day to dynamically adjust the lamp switch time, thus not only saving will be more convenient; secondly, install infrared sensor, radar or camera to measure the real-time traffic flow data, people in the Street and then, automatically reduce the brightness of the streetlight basis, or interval lights. However, supply chain engineer technical director Liu Hongbin Shandong Wisdom Life Data Systems Co. Ltd., said this: "this solution is not mature, the accuracy rate is not too high, only in the suburbs et al traffic particularly where few effect is good. To compare the current popularity of the interval on function as an example, the accurate rate is not too high in the case of interval lights may cause light dead, driving safety." Centralized management has been out! Distributed management become the trend in the development of as mentioned in the street lamp control to save energy by means of intelligent street lamp, below about the control system communication architecture. At present, the intelligent lighting system is usually equipped with a gateway in every kilometer range, dozens of lights within the scope of the use of ZigBee, PLC, 433 and other means of communication and connection to the gateway, the gateway through the 3G and 4G transmission to the cloud. In addition, intelligent lighting scheme of HUAWEI's first use of the IPv6 based 6LoWPAN technology to complete the road communication, it has low power consumption, since the wireless networking features and fast cure. It is reported that ZigBee is a new generation of smart grid standards in SEP2.0 has adopted 6LoWPAN technology, with the smart grid deployment, the future will completely replace ZigBee standard. Thus, 6LoWPAN will become a mainstream communication in the future of intelligent street lamp. : Based on intelligent lighting communication architecture lamp ZigBee communication protocol is a switch, the communication architecture mentioned above based on intelligent control dimming. While the traditional street lamp generally adopts centralized control mode, the installation of a controller only in gateway. The usual control street lamp switch, adjust the brightness of the operation to go through the gateway, gateway once problems or broken network, street lamp can not be controlled by more than one day in the street, "and It is often seen. Zhenghui phenomenon. In view of this situation, the local controller is intelligent lights are installed in each scheme of intelligent street lamp, written some simple control instructions, even off the net every street lamp can still work. More importantly, install controller, monitoring module in each street after street, city managers can manage for each lamp, distributed control. Not only the lamp status, position, power and other information at a glance, when the lamp fails the system will automatically send notification sent to the administrator timely maintenance, this management model has changed the past manual inspection situation, save manpower cost, and improve management efficiency. Intelligent lighting will produce a new business model, new industry chain participation scheme for street lamp intelligent benefits obviously, but our city lights are still non intelligent traditional sodium lamp, meet the intelligent transformation of the resistance is not really small. First of all, the high cost of LED street to a substantial energy saving all need to replace sodium lamp LED lamp, LED lamp and a cost of more than 1000 yuan; secondly, the construction speed of the intelligent upgrade slow, high cost: if the intelligent transformation of sodium lamp, only need to add a controller at every street lamp pole, the transformation only needs more than a week; and to replace the LED sodium lamp, the transformation to a few months. Finally, although has made considerable progress, LED lamps with still some defects: such as penetration is not strong enough, to illuminate the fog and haze; scattering ability than sodium, irradiation range." Liu Hongbin said. Although intelligent resistance is not small, but the government's determination to not small. At present, more than 95% have more than 76% sub provincial city, prefecture level city, a total of about more than 500 city are put forward to build a smart city. However, the wisdom of the city is still in the initial stage, the system construction is too complex, and the city of intelligent lighting project will undoubtedly become the best place to fall. To promote the transformation in government policy support and the LED industry, the city will further the development of intelligent street lamp. In the near future, based on the intelligent street lamp in the wisdom of the city and become the carrier of intelligence traffic, and play more roles. First, light poles will be added a variety of equipment. For example a lamppost with electronic display to provide convenient information and for advertising operations; installed cameras monitoring road condition; there is a key alarm button on a lamppost. Second, an environmental meteorological station. The increase of PM2.5, temperature and humidity sensor in the intelligent gateway, broadcast the local meteorological and environmental city comprehensive information on the display screen. Third, laying fiber in the street line, the street became the WiFi base station, the implementation of the WiFi hotspot. Summary thus, city street in addition to all kinds of intelligent control and energy saving, in the future is no longer a lamppost in the traditional sense, but the evolution of intelligent city lighting is even part of the wisdom of the city. This will involve a huge industrial chain, chip, sensor, LED lighting, communication module, cloud platform will have a huge market opportunity, HUAWEI, ZTE, CISCO's strong incoming is not hard to understand.
