Three Internet of Things Technologies Analyze the Construction of Smart Cities
The construction of a smart city has become more and more grounded in people's daily life from a high-level concept. Let us realize the convenience that various intelligent systems bring to life. For example, if you go to the government, you don’t have to run so much. Many times, as long as you submit some information online, you can choose the intelligent transportation system to avoid the congested roads. In fact, there are still many intelligent systems in the life that use the Internet of Things technology. Let's take a look at the application of this technology in the construction of smart cities.
First, smart government applications
1. Through the government cloud, government data exchange platform and perfect government information resource catalogue system, realize cross-departmental information sharing and resource integration, and establish an integrated government resource system.
2. By integrating government portals, call centers and other related government service resources, the government, enterprises and the public can obtain consistent and integrated government services through the Internet, telephone, mobile terminals and other channels anytime and anywhere.
3. Through resource sharing and process integration, improve the government service supervision channels, provide one-stop services for enterprises, other social organizations and the public, so that you can handle related business anytime, anywhere without leaving your home.
4. Through the establishment of a sound information collection system, the use of powerful data mining, processing and other massive data calculation methods, as well as scientific intelligent analysis of collaborative decision-making systems to achieve government science, intelligent decision-making.
Second, smart logistics applications
Diversified data collection and sensing technology. Intelligent logistics based on the Internet of Things is faced with various types of data with diverse forms and extremely complex information relationships. Diversified data collection and sensing technologies provide several technical support for smart logistics.
A reliable data transmission technology supported by ubiquitous networks. With the development of the Internet of Things, the ubiquitous network will become the infrastructure of the information communication network. Based on the integration of other networks, it will provide reliable data transmission technology for smart logistics and provide people with all kinds of information accurately.
Intelligent decision making, security assurance and management techniques based on massive information resources. The processing and processing of massive sensing information of the Internet of Things is the premise of smart logistics for intelligent decision-making.
Finally, smart transportation applications
1. Emergency rescue system. When an emergency occurs, the owner presses the emergency button installed on the vehicle to connect to the customer service center via wireless communication. The customer service staff can accurately locate the rescue through the GPS technology and deliver the rescue to the owner. In the rescue process, the customer service staff can not only communicate with the owner of the car online, but also can dispatch rescue resources in real time to minimize the loss of life and property of the owner.
2. Intelligent navigation system. The current trial route recommendation system can recommend the shortest path, the optimal time path based on driver demand and real-time traffic information, and even recommend the route most likely to carry passengers for taxi drivers.
3. Dynamically display the occupancy status of the parking space, monitor the usage status of the entire parking lot in real time; fast path algorithm guides the car to quickly enter the idle parking space. It is possible to statistically calculate the time-slot occupancy rate, daily usage or usage rate of the parking lot, and assist in knowing the parking management arrangement.
The construction of a smart city is a long-term stage that will always be accompanied by the development of technology and new wisdom needs to be integrated into urban development. Therefore, the construction of smart cities needs to be based on the development and construction of a completely digital city. This is an objective requirement for the development of smart cities.
