Today, technology is rising, and more and more attention is being paid worldwide. People are more and more interested in the development trend of technology and are making full use of these technologies. For example, smart city is the trend technology in the next few years.

By 2022, the investment in smart cities is expected to reach a peak of US $158 billion. It is expected that in the Americas, the expenditure of general public transport sector will grow rapidly, and fixed visual monitoring will be carried out at the same time. This will be a year of rapid growth.

It is estimated that by 2023, 50% of cities will use the platform to rely on their own crowdsourcing to participate in urban budget and decision-making. In 2021, the global smart city expenditure is expected to reach 34.5 billion dollars. The share of smart energy in the global smart city market is 15.8%.

Without smart home, smart city will not be complete. Therefore, the global smart home market is predicted to reach 40.9 billion dollars by 2021. The sales of home technology in 2018 is about 4.6 dollars, which is expected to increase by at least 10% by 2021. This year, the income of the global home safety market is expected to be 2.58 billion dollars.

The trend of Internet of Things smart city will change the future

The following are the seven major trends of technology development in smart cities:

Traffic congestion sensor

The intelligent transportation system uses IoT sensors to detect congestion and bottlenecks in the traffic mode. They also rely on cameras to improve speed and collect evidence for traffic violations. In doing so, these devices collect constant data that can be used by the urban DoT to make the portable network more secure and better. By developing applications on intelligent transportation systems, transportation systems have become the basis for world growth.

Bridge inspection system

The sensors will monitor the structural stability of the bridge and inform the city engineer of any problems. The UAV is used to check the problems in the difficult to reach bridge area through the intelligent bridge system application, and engineers can quickly find the location to solve the problems. The system fully complies with non-destructive testing standards and uses sensors connected to buildings to provide continuous monitoring of building health. These sensors cannot replace traditional inspections, but can serve as early warning systems so that local authorities or asset owners can anticipate and schedule on-site inspections and maintenance.

Waste Management Sensors

A better way to clean cities using IoT Smart technology. IoT sensors can detect the amount of waste around cities so that sanitation workers can clean the waste in their routes. The Internet of Things will fill the level sensor, realize the automation of robots and enhance waste, so that the framework of senior executives can play a role together, so that the association can protect and become more environmentally friendly. In short, IoT sensors provide a better choice for cities that want to take care of sustainable and interconnected growth.

Lighting sensor

Modern intelligent lighting systems are based on light emitting diode (LED) technology and involve cutting-edge technology drivers. At present, lighting systems are being developed to support different wireless communication interfaces compatible with IoT environments. LED lights are weather adaptive and will automatically send communications to the Ministry of Public Works when bulbs need to be replaced with IoT based applications.

Fire detection

The sensor monitors conditions in entertainment places and dense areas that may be prone to fire. Sensors can also distinguish between fires in buildings, and they can alert nearby emergency services. The remote monitoring and diagnostic functions of the IoT system can help firefighters know the location of people and trucks in advance. The Internet of Things will warn firefighters and smoke alarm places, signs that send warm signals or water areas that are implementing flow switching.

Parking sensor application

You also know about parking applications that can be used in conjunction with intelligent parking meters to inform drivers where parking spaces are available. Intelligent parking development means an Internet of Things based system that sends data about free and occupied parking spaces through online or mobile applications. Each parking space has Internet of Things equipment, including sensors and microcontrollers. Users receive real-time updates on all parking space offerings and select simple updates. Again, the application provides information about previous parking receipts and sessions.

Water and wastewater monitoring

The Internet of Things in water treatment uses the Internet of Things smart city sensors installed at various locations in the water system. These sensors collect data from various locations and send it back to the monitoring system. Intelligent water sensors with IoT enabled can track water quality and temperature. The Internet of Things can also play a role in leak detection and send instant alerts. These notifications are immediate, and if an engineer has to look at the volume by hand or on foot, it may take hours to detect resistance. Now, it allows engineers to deal with difficult problems faster, find answers and move on to the next task.

Finally, another great advantage of the Internet of Things in wastewater management is the detection of residual chemicals after treatment. This will make it impossible to calculate the efficacy of the selected treatment process and ensure that the release of chemicals remains within the permissible limits.

If you are trying to find these trends in the development of IoT smart cities in 2021, these trends are very effective and useful in the world. Most people do not understand these emerging technologies. By 2021, older and more mature technologies will not be out of date. On the contrary, they will remain an important factor and will have the convenience to transform enterprise and private life. In any case, the development track of the 2021 transformation plan will be closely related to the development of existing technologies.
