In recent years, the national policy has been pushing the wisdom of the city, and Intelligent street lighting as the most basic public facilities in the construction of Intelligent city, has attracted much attention. And according to the "Thirteen-Five" urban green lighting planning goals, China will be 46% of the growth rate of 12 million new LED lights, and the transformation of 50% of the existing street lamps, the total scale of 29 billion yuan. The huge market naturally attracts many enterprises ' eyes, but there are many problems to be solved.
Street Lamp Control market blossoming, standard compatibility is the trend
Intelligent lighting many standards have not been unified, and in outdoor lighting, especially intelligent street lighting, in addition to the mainstream power line carrier communication technology (cable control technology), there are Lora, ZigBee-oriented wireless control technology.
Lora is able to communicate at a lower power distance, using battery power or other energy-collecting methods, and lower data rates extend battery life and increase network capacity. The Lora signal is also very powerful for building penetration, and is ideal for low-cost, large-scale IoT deployments.
The ZigBee technology is born in the application environment complex industrial place, also therefore has the extremely high security, the reliability, the low power consumption, the self-organization network ability and so on the merit, for the intelligent Illumination Street lamp, the control system can the complex changeable environment natural more reliable.
However, with the advent of Nb-iot technology, the industry for Nb-iot will become the mainstream of Internet wireless control technology calls increasingly high. In the last installment, we also introduced in detail the technical advantages and application scenarios of Nb-iot.
In addition to the advantages of low power consumption, low cost and high stability, compared with Lora and ZigBee, Nb-iot's biggest feature is that the transmission distance reaches an astonishing 10km and can cover a small county seat. And a base station can take $number terminals, which means that the management of each street lamp is easy and easy, while the depth of the underground parking lot, underground pipelines and other fields. At present, many intelligent street lighting projects have used Nb-iot technology.
Nuclear "core" is the main power of innovation
The development of Intelligent Street lamp also puts forward new requirements for intelligent control chip in its application system: with the improvement of intelligent control chip and driving power technology, the problems of heat dissipation, light decay, power supply and transmission stability of LED street lamps are solved, and the continuous and rapid decline of the price also improves the cost-performance of the intelligent streetlight System.
In addition, as more functions are integrated into the smart chip, the chip has become the main technology innovation components, the current smart chip not only need to be updated with intelligent control technology, power line carrier, WiFi, Bluetooth, GPRS, 4G, Rola and other communications technology according to customer requirements, Requirements can be compatible with each other, while the future Smart Street control chip is given more possibilities.
AI makes smart street lights
At present, the Intelligent Street lamp is to realize remote centralized control and management of street lamp by using power line carrier and wireless communication technology, 3G communication, cloud computing, Internet of Things and mobile network technology. It has automatic adjustment brightness, fault active alarm, lighting cable anti-theft, remote control, remote meter reading and other functions.
Intelligent street lamps can greatly enhance the level of public lighting management, save power resources, reduce the cost of operation. The essence of Intelligent Street lamp is the fine management of illumination.
It can be said that where there is a street lamp, where is the city's management area, in the era of Intelligent city, based on the city's widely distributed street lamps to establish a network of street lights, can avoid the city's basic networks of sensor facilities, the duplication of capital investment.
Today, artificial intelligence technology is in the ascendant: in the first half of this year, Coger and Alphago's man-machine war ended with Alphago's victory, which also pulled people's attention back to artificial intelligence.
The combination of streetlight control system and artificial intelligence, which is one of the urban infrastructure, has a natural advantage. The huge amount of data collected by it is only artificially processed, and it is difficult to be fully applied. The intervention of AI technology can effectively complement this short plate. In short, artificial intelligence recognizes that the potential business benefits of technology are much greater than the cost savings brought about by automation, which is mainly embodied in:
Faster action and decision making (e.g., street environment detection, planning and scheduling)
Better results (e.g., control flexibility, power monitoring, demand forecasting)
Higher efficiency (i.e., better use of sensor equipment and control equipment),
Lower costs (e.g., automatic control and response mechanisms reduce labor costs)
Larger scale (i.e., large-scale tasks that cannot be carried out by human resources)
Product and service innovation (from adding new features to creating new products)
It is foreseeable that in the near future, people will see the smart street lighting system brings more surprises and convenience.
