With the widespread application of emerging information technologies such as the Internet of Things, next-generation Internet, and cloud computing, smart cities have become an inevitable trend in the future, and many cities around the world have set off a climax of smart cities. In Hong Kong, smart cities are gradually integrating into the lives of residents. Even street lights will be equipped with "smart brains", which will bring more convenience and unlimited possibilities to "Smart Hong Kong".
One shot
Street lamps are an indispensable infrastructure for urban development. They are connected to the power grid and grow taller. Adding a “smart brain†to street lamps can significantly improve the management efficiency of the city. Hong Kong Kowloon East will take the first step at the end of this year to test 7 smart street lights. The Hong Kong Innovation and Technology Bureau plans to work with various departments of the SAR Government to launch multi-functional light poles next year and install accessories on 400 pole lampposts to explore the possibility of building smart cities.
The 7-inch smart street light that will be installed in Kowloon East can be described as "one shot and more energy". It can integrate intelligent lighting, mobile network signal transmission, video surveillance, information release, PM2.5 intelligent sensing, electric vehicle charging pile and other functions. It brings a full sense of "black technology".
The joint venture between the Science and Technology Bureau and various departments will be even larger. 400 to 500 smart street lamps will be installed in Causeway Bay, Central and Tsim Sha Tsui, equipped with multi-function sensors and data networks to collect various types of city data. For example, weather data can monitor microclimate change in one day, traffic data can help regulate traffic lights, and guide traffic flow, etc. Wireless networks can provide WiFi hotspots and 5G small base stations. A spokesperson for the Office of the Chief Information Officer of the SAR Government said that the relevant plan was announced as soon as possible in March.
Environmentally efficient
The biggest advantage of smart street lights is environmental protection and high efficiency. The light source of the smart street lamp adopts LED illumination, and the soft warm white light is illuminated at night, and can be automatically dimmed according to the traffic flow and weather conditions, so that the on-demand illumination can save more than 60% energy than the conventional street lamp. For street lighting maintenance personnel, each of these street lights can be individually monitored and monitored. The operation of each street lamp can be monitored in real time on the computer, eliminating the need for manual night inspection. Greatly save their workload.
The camera under the illuminator can be used for security purposes or to monitor the vehicle, detect traffic flow and flow data in the area, and provide big data collection and calculation functions.
The sensors on the poles are responsible for collecting environmental data such as weather information, noise, and air pollution data. Display these data on the electronic screen on the side of the pole. The temperature, humidity, wind speed, wind direction, PM2.5 and other information in the area will be clear at a glance.
At the top of the streetlight is a WiFi hotspot or 5G base station for wireless networks, and the bottom is an electric vehicle charging post. After the mobile network signal is opened, Hong Kong citizens can connect to the Internet for free by simply turning on the streetlight pole and turning on the WiFi of the mobile phone. With the mobile APP software, it is convenient and quick to charge the electric car.
Open platform
There are precedents for the construction of smart street lamps in Chicago, Taipei, Beijing, Singapore, etc. How can Hong Kong learn from experience and brainstorm? Lu Siyuan, an expert on the application of smart city technology in Asia, believes that the SAR government should open its mind to open the application of data collected by sensors and cameras. On the other hand, it should consider "opening the lamppost" so that various enterprises can put themselves in themselves. Other sensors developed are put in place to encourage more innovation. "On the government alone, we are already lagging behind some areas. It is most important to open up the platform so that everyone can make innovation together."
The German technology company Siemens has set up a “Smart City Digital Center†in the Hong Kong Science Park Park to provide multiple smart city application development tools. A Siemens spokesperson also suggested that Hong Kong should establish a cloud platform widely and open up the data to encourage the business community to use the data collected by smart street lamps to develop more value-added services for the public. “Building an IoT system where the lamp posts are connected to the management module, city management will be more efficient.â€
