The development of smart city not far from it, because it is everywhere......

With the rise of the smart city concept, the layout of major companies around the smart city related fields. As the street can be seen everywhere in the city infrastructure, its importance is self-evident. So, the future of smart lighting which will bring changes to the street? For the construction of smart city and what it means? In this paper, Deutsche Telekom Ag (German: Deutsche Telekom AG) machine to machine capacity center vice president J RGENHASE said that the street will become the foundation of wisdom municipal network, providing services in terms of parking control, waste management and traffic flow.

The next generation of street lighting network. The world has been in the city can be intelligent lighting remote control system. Not only can reduce the cost of electricity, but also can realize the demand driven lighting, reducing carbon dioxide emissions. The current design even further: "networking experts will light" as a multifunctional communication network node of smart city "".

Now, the main use of street lighting. However, the future will play a more functional street. For example, the trash is full, the lamp will inform the garbage collection service center, or recorded changes in traffic volume, and the data input of the intelligent transportation system (ITS). Street lighting will no longer be isolated, but the network part of city infrastructure.

This vision is based on the Internet of things (IoT) and the rise of the concept of smart city. The object and the position of every imaginable can be networked: cars, containers, and even street parking lot, watches, glasses and pen. They can be all kinds of parameter measurement in the environment, can also be the daily work of digital. The core of this change is the machine to machine (M2M) automatic switching between communication and networking equipment or between the control center and data.

Smart city solutions are considered to reduce energy and maintenance costs, the key regulatory requirements in accordance with the climate protection and provide better service to the public. Intelligent lighting plays a central role in this respect. In fact, in many city, street problems accounted for about 20% of public complaints, the intelligent system can make the maintenance process automation. Plus LED, programmable lighting management system will be the city power to reduce the cost of 70%.

Not only artificial light

Machine to machine (M2M) what is communication? For example, here. For example, in the industrial field, M2M is used for remote machines and equipment maintenance. Technical staff can see the wear parts of the situation in the distance. If an error occurs or the system detects the preset mode, will automatically alert the staff. This improves the production, maintenance and use of resources of transparency. Intelligent lighting system provides similar benefits. In order to identify defective lamps, you do not need to rely on night patrol or public complaints, the system can display the state of the lighting in the center of things.

When the things around us is intelligent, their function is more. For example, in Boston Park, there are intelligent people can be charged to the bench, intelligent mobile phone and tablet computer. At the same time, the park bench also measured environmental factors, such as air quality and noise level. They become a "charging station" and "measuring instrument". Similarly, the network is not only used for lighting the lamp appliance, they become more nodes in the network function.

The basic architecture of intelligent lighting

In order to act as a multifunctional network, intelligent lighting solutions must satisfy the requirements of what? The basic structure must conform to the current diversified market solutions. First of all, technical personnel need to install lamps equipped with electronic equipment, electronic equipment or small boxes in the street outside, either in the lamps. Or, to directly integrate hardware lamp manufacturers. Of course, some of the old type lamp may need to be updated to more efficient LED. Once the upgrade, these lamps can be integrated into a short distance network.

In addition to lighting hardware, mobile communication gateway is used for remote data exchange. These can be connected to the street or placed in the distribution network. Usually, they are fixed, so each gateway can reach the maximum number of nodes. Receiving information from the node and forwards it to the cloud server infrastructure or local server. Similarly, the gateway sends control instruction to nodes, and indicating switch or dimmer.

The neural pathway of the wisdom of the city ""

A combination of node and gateway has double network. Node narrowband network for sensor applications, such as smart metering. The broadband network gateway for data intensive applications, such as the use of cameras to monitor flow. The formation of mesh network topology. Each node which is connected with one or more other nodes. Usually, a mesh network can self repair, so it has very high reliability. When a node fails, the network will automatically through other nodes to transmit data.

In data transmission, IP standard is the foundation. The object and the location has a IP address, so it can be clearly identified. IPv6 internet protocol is considered to be an important premise of networking and smart city. Compared with the prior agreement of IPv4, it will address space to 2128 unique addresses from 232 expansion, thereby ensuring that the network city has enough address space. Low power wireless personal area network protocol IPv6 (6LoWPAN) is particularly promising. As a short-range radio technology for energy saving, especially suitable for sensor networks 6LoWPAN.

operating system

In addition to the data transmission standard, interoperable management system software is also very important. Most of the intelligent lighting solutions provided by Web based on the entrance, the entrance can be programmed and management of light, such as setting the lamp open and closed cycle. When combined with the luminance and motion sensors, can set more complex scenarios, such as the day lights brighter; in one of the few areas, only when the motion sensor detects a person after, will turn on the lights.

In order to support the application of smart city more, city lighting management system must not be closed, should be extended by third party applications. Ideally, the implementation of a city should not only limited the application of entrance management, can provide docking point for government agencies, citizens and the private sector.

Need the cooperation of all parties

In addition to funding, smart city solutions need to break through the obstacle is to rationalize the various relationships. The needs of different industry cooperation, have different abilities, especially the intelligent lighting system. In addition to the traditional lamps and lamp manufacturers, hardware manufacturers, software vendors and service providers are involved. However, negotiations with each participant of each contract may be very difficult - especially for customers must ensure that the component used to be compatible with.

In order to speed up the process of German Telecom and other international mobile operators will enter the market. This is based on an extensive network of partners, covering all areas of the network ecosystem. For example, the old street is a challenge. In order to upgrade these lights, specific components and professional knowledge. Partner network including professional repair history of street lamps and the related process of small companies. Cooperation is the key to the city network, intelligent lighting is a promising starting point. (compiled: LED James)
