Foreign application cases of using the Internet of Things to perceive environmental changes

Between France and Switzerland, the Alps stand tall and steep, standing in the north of Europe. The permafrost and rock formations accumulated in high-altitude areas have undergone four seasons of climate change and erosion by strong winds. The changes that have occurred over the years often have a great impact on the production and life of climbers and local residents. It is necessary to obtain information on these changes in the natural environment. Data requires long-term monitoring of the area, but the environment and location of the area determine that it cannot be monitored manually. In the past, this has always been an unsolvable problem.
But not long ago, a project called PermaSenseProject changed this situation. The PermaSenseProject plan hopes to achieve long-term monitoring of the geology and environmental conditions of the Swiss Alps through the application of wireless sensing technology in the Internet of Things (IoT). The monitoring site no longer requires human involvement, but a large-scale in-depth monitoring of the entire Alps through wireless sensors, including: the impact of temperature changes on the structure of the mountain slope and the changes in soil water seepage by climate. Participating in the project, the University of Basel in Switzerland, the University of Zurich, and the ETH Zurich have sent research teams including experts in the fields of computer, network engineering, geography and information science. According to them, the plan applies the wireless sensor network technology in the Internet of Things to long-term monitoring of the geological conditions of the Swiss Alps. The collected data can be used as a reference for natural environment research, and the analyzed information can also be used as Get advance warnings of natural disasters such as landslides and rockfalls in advance. Those familiar with the plan revealed that the plan was formulated for two main purposes: one is to set up a wireless sensor network to measure the environmental conditions in remote and harsh areas; the other is to collect environmental data, understand the process of change, and use climate change data for Natural disaster monitoring.
Give me an Internet of Things I can perceive the earth
In recent years, geological disasters such as earthquakes and tsunamis have occurred frequently, which have severely affected human lives and lives. People have begun to realize that global warming has put the world on the same dangerous edge. Humans need to pay more attention to changes in the natural environment. How to respond to changes in the natural environment through technology:
In Queensland, Australia, people are trying the “smart bridge” experiment. By installing various sensors on a bridge, you can not only tell the city manager how many cars there are on the bridge, how heavy the car is, how much pollution the car is, and whether the car is new or old, but can also tell people about the car. How much pressure the car puts on the entire concrete structure of the bridge. As a result, the traffic management department can conduct real-time assessment and obtain data on the structural strength of the bridge. Once the pressure exceeds the set limit value, the traffic management department can obtain an alert and find it in time.
In Singapore, people can get traffic jam forecasts just like weather forecasts. Through the sensors buried on the road and the probes on the traffic lights, the driver can not only see where there is a traffic jam, but also can predict in advance where there will be traffic jam after 10 to 20 minutes, so as to choose a smoother road.
In New York, a smart city rapid response system for public safety has been established, which is a “crime information warehouse.” Through the information in these information warehouses, the New York police can learn more about the behavior of criminals. That is to say, once a criminal behavior appears a little bit, the New York police can make predictions based on this information and prevent similar crimes. The behavior occurs.
Stockholm, Sweden has established a smart transportation system to charge traffic according to different levels of congestion. Through such a smart transportation system, Stockholm’s entire car usage has been reduced by 25%, carbon emissions have been reduced by 14%, and better than expected results have been achieved in terms of environmental protection and pollution prevention. In terms of per capita carbon emissions, it has become a leader in Europe, and the average carbon emissions per capita has dropped to 4 tons per year. The average in Europe is 6 tons/year per person, and 20 tons/year in the United States.
China, which suffers from food safety hazards, has gradually implemented an intelligent food traceability system since the 2008 Beijing Olympics. Food from farms, markets, and citizens are included in this traceability system. Once food problems arise , The root cause of the accident can be found in time.
All kinds of sensor technology, communication technology, wireless technology, and network technology together form a smart network with the Internet of Things as the core. Aristotle once said, “Give me a fulcrum and I can pry up the earth.” Now with the development of technology, this rhetoric can be changed with the times: “Give me an Internet of Things, I can perceive Earth”.
