Hong Kong street lights will be fitted with "smart brain"
2018-02-24

With the widespread application of emerging information technologies such as Internet of Things, next generation Internet and cloud computing, smart cities have become the inevitable trend of future development. Climax of smart city construction is set off in many places in the world. In Hong Kong, smart cities gradually integrate into the life of residents. Even the street lights will be fitted with a "brain of intelligence" that will bring more convenience and limitless possibilities to "Wisdom Hong Kong".



A multi-pole


Street lighting is an indispensable infrastructure for urban development. It connects to the power grid and grows tall. Adding "smart brain" to the street light can obviously improve the management efficiency of the city. Kowloon East, Hong Kong will take the first step towards the end of this year by installing seven smart street lamps. The Hong Kong Agency for Innovation and Technology plans to work with various departments of the SAR government to pilot a multi-purpose smart lamp post next year to retrofit 400-street lamp posts with accessories to explore the possibilities of smart city construction.


East Kowloon will test the installation of seven smart street lamp, described as "a multi-function", you can set smart lighting, mobile network signal transmission, video surveillance, information dissemination, PM2.5 intelligent perception, electric car charging pile and other functions in one , Bringing full of "black technology" both visual sense.


With a larger joint trial by the Bureau and various departments, 400 to 500 smart street lamps will be set up in areas such as Causeway Bay, Central and Tsim Sha Tsui and equipped with multi-function sensors and data networks to collect various types of urban data, For example, the weather data can be used to monitor the micro-climate changes in a day. Traffic information helps to control traffic lights and divert traffic flow. Wireless networks can provide WiFi hotspots and 5G small base stations. A spokesman for the office of the Chief Information Officer of the HKSAR Government said the plan was announced as soon as March.


Environmental protection and high efficiency


The biggest advantage of smart street lamp is environmental protection and high efficiency. The light source of the smart street lamp adopts LED lighting, the warm night light shines out is the soft warm white light, and can automatically adjust the light according to the traffic flow and the weather condition so as to achieve lighting on demand and save energy by more than 60% compared with the conventional street light. For the operation and maintenance personnel, the street lamps can be individually monitored and monitored for each single lamp. The operation of each street lamp can be monitored on the computer in real time, which eliminates the need for artificial night inspection. Great savings in their workload.


Under the lighting of the camera can be used for security purposes or monitoring vehicles, traffic detection within the region, the flow of data, to provide big data collection and calculation functions.


The sensors on the light poles are responsible for collecting environmental data such as weather information, noise, air pollution data and the like. The data displayed on the pole side of the electronic screen, the region's temperature, humidity, wind speed, wind direction, PM2.5 and other information will be clear at a glance.


The top of the street lamp is installed WiFi hotspot or 5G base station of wireless network, the bottom is electric car charging pile. After opening the mobile network signal operation, Hong Kong residents as long as walking in the light pole near, open the phone's WiFi, you can connect to the Internet for free. By mobile phone APP software can be scheduled to charge electric vehicles, convenient and quick.


Open platform


There are precedents for the construction of smart street lamps in Chicago, Taipei, Beijing and Singapore. How can Hong Kong draw lessons from experience and brainstorm? Lu Siyuan, an expert on smart city technology in Asia, believes that the SAR government should be open to the public and apply the data collected by sensors and cameras to open applications. On the other hand, "open lamp posts" should be considered so that various types of enterprises can take themselves Other sensors developed were added to encourage more innovation. "By the government alone, we are lagging behind some regions and opening up a platform for innovation is the most important thing for everyone."


German technology company Siemens set up a "smart city digital center" in the Hong Kong Science Park to provide multiple smart city application development tools. Siemens spokesman also suggested that Hong Kong should set up a cloud platform in a broad manner to open up the data and encourage businesses to use data collected by smart streetlights to develop more value-added services for the public. "Establishing an IoT system that connects the lampposts and management modules will make city management more efficient."
