How Europe is building smart cities

In fact, you can take a look at some of the cities where other smart city street lights are built, and it is no longer only Barceló.

Shanji: Base station + recognition vehicle collision + ......

The City of Los Angeles has a massive network of smart, connected streetlights, with more than 200,000 sets of streetlights across the city serving citizens on city roads, highways, tunnels, and sidewalks. In addition to lighting and networking, new acoustic sensors and environmental noise monitoring sensors can detect vehicle collisions and provide timely information directly to the city's emergency communications system, helping police, fire and emergency services to shorten response times and get patients in the first place.

Paris: seat + wifi + ......

The street lamp on the left was installed in Paris during the 21st United Nations Climate Change Conference in 2015, and in addition to its basic function as a street lamp, it also provides a seat for people to rest. The aluminium vault allows the light to diverge directly downward, reducing light pollution and improving energy efficiency. On the other side of the vault are solar panels that provide 3 hours of electricity to the street lights, which have a small hole to charge pedestrians' mobile phones.

This street light was designed by the New York start-up engoplanet.

Four were installed in a Las Vegas plaza and eight kinetic power panels were installed at ground level (left). Electricity is mainly provided by solar panels, but when the weather is dark in the morning and the battery is low in the evening, the kinetic panels can use the footsteps of pedestrians to charge the batteries, generating about 4-8 watts of electricity per step. This system is not only a power supply system for street lights, but also for CCTV, Wi-Fi hotspots and mobile phone charging stations in the plaza, which completely disconnects the entire plaza from the power grid.

In addition to this, it has other functions: detecting air quality, temperature, humidity.

San Diego: Find a parking space + detect gunshots + ......

Since 2015, American telecommunications giant AT&T and General Electric (GE) have joined forces to install cameras, microphones and sensors on 3,200 street lights in San Diego, California (left). These street lights can monitor traffic, crowd size, weather, and even gunshots. For example, identifying and pointing out vacant parking spaces to drivers, alerting traffic enforcers to illegally parked cars, and monitoring and recording traffic jam information for future traffic signal adjustments.

Considering the security situation in the United States, smart street lights can also easily connect to existing networks, automatically locating gunshots over an area of about 10 square kilometers or more. Or detect sounds such as glass breaking or vehicle collisions and automatically report a dangerous situation to the police.

In November 2008, at the Council on Foreign Relations held in New York, IBM proposed the concept of "Smart Earth", which in turn triggered a boom in the construction of smart cities.

In 2009, the City of Dubuque partnered with IBM to build the first smart city in the United States. Using the Internet of Things technology, in a community of 60,000 residents, various urban utilities (water, electricity, oil, gas, transportation, public services, etc.) are connected, and various data are monitored, analyzed, and integrated to make intelligent responses and better serve citizens. Dubuque's first step was to install digitally controlled water and electricity meters to all homes and shops, including low-flow sensor technology to prevent waste from water and electricity leaks.

At the same time, a comprehensive monitoring platform is built to analyze, integrate and display data in a timely manner, so that the use of resources in the whole city is clear at a glance. What's more, the city of Dubuque disseminates this information to individuals and businesses so that they have a clearer understanding of their energy consumption and a greater sense of responsibility for sustainable development.

1. Concept and goal: The concept goal of European smart city practice is more inclined to practical life and environmental improvement; The perspective of Chinese concepts is more macro, biased towards policy management and overall urban optimization.

2. Application fields: Europe is biased towards energy and environment, and China is biased towards data and management. In addition to the first-tier cities, the vast majority of cities in China are still in the stage of strengthening the construction of information infrastructure.

For second- and third-tier cities, the popularization of IoT systems, big data collection, data disclosure, and industrial transformation are the key areas of development of smart cities in the future.

3. Legal supervision: Europe is relatively mature and standardized, and China is still exploring and developing. In the construction of smart cities in Europe, local laws and policies have a greater impact, and EU laws and policies play an indirect role.

Due to the strong independence and high financial independence of European cities, the function of the EU's large policy framework tends to guide, coordinate and motivate enterprises, which only has an indirect impact. In the construction of smart cities in China, national laws and policies have a greater impact.

Smart cities involve many industrial links, and we estimate that the total investment related to smart cities may reach 9700-4100 billion yuan, which will become the focus of the next round of investment cycle. China's smart city construction experienced the 2013 pilot approval peak period, in 2014 is expected to usher in the initial implementation of the plan, because most of the 193 pilot cities are still in the planning stage, China's smart city construction industry investment growth will be significantly improved.

The financing problem in smart cities has always been a concern for everyone, but with the application of the BT model in the construction of smart cities, it can effectively solve the huge capital demand. On the other hand, the construction of smart cities is mainly the investment in informatization, and the proportion of informatization investment in fiscal expenditure is low, and the willingness to invest in informatization is strong. And with the country's increasing attention to the informatization strategy, the level of informatization investment in the future will be in line with international standards.

The diversification of financing models for smart city construction ensures the funding of smart city construction to a certain extent.

According to the "2015-2020 China Smart City Construction Development Prospect and Investment Analysis Report" released by the Prospective Industry Research Institute, China's smart city construction-related investment is expected to exceed 2 trillion yuan in the next 10 years, covering intelligent transportation, public safety, digital urban management, smart medical and other solution markets. Since 2010, China's smart city construction investment has maintained an average annual growth rate of about 14%, coupled with the large-scale landing of smart cities in the future, the growth rate of industry investment will continue to maintain an upward trend.
