Hong Kong To Build Smart City

- Jul 01, 2019-

With the wide application of emerging information technologies such as the Internet of things, the next generation Internet and cloud computing, smart cities have become an inevitable trend of future development, and the construction of smart cities has reached a climax in many parts of the world.In Hong Kong, smart city is gradually integrated into residents' life. Even street lamps will be equipped with "smart brain", bringing more convenience and infinite possibilities to "smart Hong Kong".


A rod pluripotent


Street lamps are an indispensable infrastructure for urban development. They are connected to the power grid and grow tall. Adding "smart brains" to street lamps can significantly improve the efficiency of urban management.Hong Kong's Kowloon east will take the first step towards fitting out seven smart street lamps by the end of this year.Hong Kong's innovation and technology bureau plans to work with various departments of the hksar government to pilot a multi-functional smart lamppost next year, adding accessories to 400 lamp posts to explore the possibility of building a smart city.


The seven smart street lamps, which will be installed in Kowloon east, are "multi-functional", and can integrate intelligent lighting, mobile network signal transmission, video monitoring, information release, PM2.5 intelligent perception, electric vehicle charging pile and other functions, bringing a sense of "black technology".


Chuangke bureau and multiple departments jointly test on a much larger scale, will be in causeway bay, central and Tsim Sha Tsui area set up 400-500 intelligent street lamp, equipped with multi-functional sensor, data network, such as facilities, data can be collected various types of city, such as the weather data can be detected within a day of micro climate transformation, traffic information helps to regulate traffic lights, traffic channel flow, etc, the wireless network can provide wi-fi hotspots and 5 g small base stations, etc.A spokesman for the office of the government chief information officer said the plan could be announced as soon as march.

Environmental protection and efficient


The biggest advantage of smart street lamps is environmental protection and high efficiency.LED lighting is used for smart street lamps. At night, soft warm white light comes out, and it can automatically adjust the light according to the traffic flow and weather conditions, so as to illuminate on demand and save more than 60% energy than conventional street lamps.For the street lamp maintenance and repair personnel, each single lamp of these street lamps can be independently monitored and monitored, and the operation of each street lamp can be monitored in real time on the computer, which saves the manual night inspection and greatly saves their workload.


The camera under the light can be used for security purposes or monitoring vehicles, detecting the traffic flow and people flow data in the area, and providing big data collection and calculation functions.


Sensors on lampposts collect environmental data, such as weather information, noise and air pollution data.When these data are displayed on the electronic screen hanging on the side of the lamp pole, the temperature, humidity, wind speed, wind direction, PM2.5 and other information in the area will be clear at a glance.


The top of the street lamp is installed with WiFi hotspot or 5G base station of wireless network, and the bottom is charging pile of electric vehicle.Once the mobile network signals are up and running, Hong Kong residents can connect to the Internet for free by simply walking near a lamppost and turning on their mobile phones' WiFi.The mobile phone APP can charge the electric vehicle by appointment, which is convenient and fast.

Open platform


Smart street lighting has been built in Chicago, Taipei, Beijing, Singapore and other places.Lu siyuan, an expert on the application of smart city technology in Asia, said the SAR government should be open-minded. On the one hand, it should open the application of data collected from sensors and cameras, and on the other hand, it should consider "opening lamp-posts" to allow various enterprises to put other sensors developed by themselves to encourage more innovation."With the government alone, we are already behind some regions. It is important to open the platform so that we can do innovation together."


Siemens, a German technology company, has set up a smart city digital centre in the Hong Kong science park to provide a number of smart city application development tools.A Siemens spokesman also suggested that Hong Kong should establish an extensive cloud platform to open up its data and encourage the business community to use the data collected by smart street lamps to develop more value-added services for the public."Urban management will be more efficient if we build an Internet of things system that connects lamp posts with management modules."
