how 3,000 streetlights turned san diego into america’s smartest city - all in one solar led street light

Perhaps no metropolitan area in the United States is more acclaimed for its smart city plan than San Diego. The city of 1.
Four million people（
If you calculate the area around, it's more than three million)
It won numerous awards and even became the subject of a 2015 National Geographic documentary about the city's efforts, the only city in the United States with such distinctive characteristics.
In fact, the work being done in the city, including municipal projects, working with local innovators, encouraging sustainable solutions and future mobility, continues to be notified, including the 2018 Smart 50 Award.
Everything started with a few lights.
Okay, more than a few. The City of (Smart)
In 2014, San Diego began working with GE to install 3,000 wireless LED street lights.
The goal is not just to save energy and reduce greenhouse gas emissions.
By networking street lights, the city can remotely control and monitor street lighting, saving the city $250,000 a year in electricity and maintenance costs.
But the authorities understand that smart lighting can bring more benefits.
So now, San Diego has started a project to install thousands of smart street lights that can monitor parking lots, monitor crime and check air quality.
Establish Your Own Internet of Things（IoT)
Some of the more advanced lights include Intel Atom processors, cameras, microphones, Wi-
FI, Bluetooth and sensors that measure temperature, air pressure, humidity and even magnetic fields.
Increased computing power allows smart lights to help drivers find open parking spaces and even inform traffic law enforcement authorities when vehicles are illegally parked.
By opening up some information for public use, the city also hopes to encourage the development of applications to help local residents and tourists, such as smartphone applications for visually impaired people, to help them navigate through streets and cities.
In addition, San Diego Deputy Chief Operating Officer David Graham told IEEE Spectrum that the city wanted to "understand which intersections are most dangerous and need to be redesigned based on information about attempted accidents, not just accident data".
"This is a new way to improve pedestrian safety.
"The authorities are also considering the use of smart lights for other purposes.
For example, lighting networks can be integrated into existing Shotspotter networks in cities.
Shotspotter is used by many municipalities to guide law enforcement officers to locate shooting sites, but Internet of Things lights in San Diego can be used to greatly expand the network and improve accuracy.
The city's sustained efforts recently won the Smart 50 Award in 2018, reportedly the world's largest Internet of Things sensor network for urban streetlights, involving public and private partnerships such as General Electric, AT&T and Qualcomm.
Eventually, the city plans to install more than 14,000 smart street lights and hopes to reduce energy costs by $2.
Four million a year.
The County as a whole, San Diego says, could eventually save taxpayers $4 million a year in better lighting solutions.
Through air, sea and road transport, the modern problems that accompany the growth, such as traffic congestion, have not escaped Santiago.
Therefore, in order to solve the traffic problem, the city's Ministry of Transport is cooperating with private companies such as Waze to use the information provided by San Diegans.
Waze's Netizens Program is working with more than 600 cities around the world to provide information not only on congestion, but also on the location of pits, dangerous deer lanes and the potential impact of road closures.
No new sensors are needed because the information comes directly from Waze users'smartphones.
"With Waze, the driving force of the community is the eyes," explains Thais Blumenthal de Moraes, who is responsible for the company's global business development.
Santiago has also made sensible efforts to improve other aspects of transport infrastructure.
For example, at San Diego International Airport, the expansion to the west of Terminal 2 is the first terminal project in the world to acquire LEED platinum and vision. -
Platinum certification.
The parking lot of Terminal 2 has advanced parking guidance technology and rainwater collection system.
Supporting Electric Vehicles（EV)
In addition, there are charging stations, and municipalities continue to work with evgo, chargepoint, Black & Veatch and San Diego Gas and Electricity Company. (SDG&E).
In fact, the grid is critical to San Diego's urban intellectualization and sustainable development plans.
According to San Diego, more than 30% of electricity is renewable, and there is no coal in SDG&E's energy mix.
Smart grid technology can help to achieve this goal by smart and efficient management and balancing of power demand in the region, increasing the use of renewable energy.
Naturally, as one of the most sunny cities in the country, Santiago has an average of 146 sunny days a year. Santiago seems to be an ideal place for a city with a net zero degree. (
Net zero means that the total amount of energy used by a city equals the total amount of renewable energy it creates. )
One example is the Solterra EcoLuxury Apartment in San Diego, a solar-based smart life community with 114 apartments.
The development projects include garages for charging electric vehicles, virtual network metering displays that allow residents to monitor energy use, and intelligent thermostats that can be programmed from anywhere and anytime through computers or smart phones.
Solterra was the first-
San Diego's solar apartment complex, the city hopes, is just the beginning of a wave of intelligent development.
Reducing power consumption and pollution through the use of intelligent systems extends to the port of San Diego.
To improve air quality, the city began to turn to the coast. -
Electric power systems allow cargo ships to plug in electricity at ports rather than running diesel engines on wharfs.
The port's Internet of Things began in 2014, when the city began to use sensors in buildings to detect energy consumption and to facilitate owners. -to-manage, real-
Time data to reduce power consumption.
Municipal authorities have also installed sensors in garbage cans to observe the real situation in the future. -
Time data applications can facilitate more efficient collection and help keep the coast clean.
At Petco Park, where the San Diego Padres baseball team is located, companies including Osisoft, Qualcomm and SDG&E are working on other Internet of Things projects to help Padres improve the efficiency of its facilities.
Through extensive data analysis, the park plans to closely monitor the use of electricity, natural gas and water, which will reduce operating costs by more than 25% over the next five years.
In fact, one of the benefits of such smart city projects is that the information generated can be used to improve services and the quality of life of citizens.
Santiago Smart City Open City Platform（SCOUP)
For example, the network automatically tracks and reduces greenhouse gas emissions from municipal facilities. (
Last year, Scoup won the California Energy Commission Energy Innovation Challenge. .
The city continues to work with companies and educational institutions, such as enVision America, technical collaborators and businesses, to address climate change and improve urban services.
It also works with the University of California at San Diego and the Metrolab Network to integrate University researchers with urban decision-making. -
Manufacturers improve infrastructure and services.
"It's all for talent," said Nicia Clark, executive director of the World Trade Center in San Diego.
"It's all about innovation and intellectual property.
For San Diego, this is a change that has changed the way we develop our economy.
"Fortunately, the region also has a history of research worth learning from.
Just north of the city, in Torry Pines, there are many R&D departments of big companies, from Novartis Pharmaceutical to Northrop Grumman Aerospace.
Some of these studies focus on future energy sources, such as fusion reactors, and transport methods, such as the only maglev train running in the United States. S.
General Atomics. (
Maglev technology is a technology that Elon Musk's drilling company plans to use for underground and high-altitude operations. -speed trains. )
General Atomic Energy was also responsible for the first batch of military UAVs.
Therefore, it may not be surprising that Santiago has recently become one of the 10 municipalities directly under the Central Government selected by the United States. S.
The Ministry of Transportation and the Federal Aviation Administration will be part of the UAV system. （UAS)
Integrated pilot project.
The UAS program aims to work with public and private sector organizations on projects aimed at integrating UAS commercial safety into the United States. S. airspace.
The city plans to fly unmanned aerial vehicles and use reconnaissance aircraft in the future. -and-
Avoid using technology, night vision and package delivery systems.
Future UAVs can be used to speed up medical delivery and assist first aid workers to help people in need.
For San Diego, it's a future that starts with changing street lights.
It turned out to be a smart idea.
