Intelligent well cover: Urban well cover has the characteristics of wide distribution and large quantity. At present, the management of municipal well covers mainly relies on manual inspection. Due to the lack of timeliness, it is unable to deal with the abnormalities of well covers quickly, resulting in potential danger. China Mobile’s NB IOT intelligent well cover scheme can call the navigation function to guide the maintenance personnel to the designated well cover site through real-time monitoring of various state information of well cover and viewing the location and basic attribute information of well cover in the jurisdiction.

Intelligent transportation: at present, China Unicom has tried to use NB IOT intelligent parking solution in Shanghai Disneyland, which can realize the function of booking and Subleasing parking spaces, solve the problem of car owners’ parking difficulties, and realize the efficient management of parking resources. The Nb IOT skill sharing bicycle solution developed by ofo and China Telecom has been applied in Changsha, which is much cheaper than the network cost of traditional cellular skills supporting the function of mobile phone unlocking and location service, and the low cost also guarantees the low rent.

Smart meter reading: traditional smart meter skills mainly include IC card, wireless remote transmission and photoelectric direct reading. They have the disadvantages of large power consumption, frequent hardware maintenance, high equipment cost, high requirements for the application environment and high wiring cost. NB IOT technology can just overcome the above problems effectively, and Nb IOT is quite suitable for the intelligent meter reading business which needs low-speed and high-frequency data communication. Moreover, smart tables are often installed in fixed locations in densely populated areas, which makes it convenient for operators to deploy networks.


1. Traffic

When it comes to the Internet of things, the first reaction of most people is smart city. Indeed, with the help of the Internet of things, the cities we live in are becoming more and more intelligent. More and more road cameras can clearly see the condition of vehicles and restrict drivers to obey the traffic rules. For example, the traffic flow monitoring system composed of sensors installed around the road can detect traffic congestion, road damage or vehicle emission pollution in a timely manner, and then provide diversion suggestions to users who carry devices with GPS positioning function and networking function. Intelligent traffic lights can sense the nearby self driving vehicles, change the traffic lights in time, and give priority to pedestrians and bicycles.

2. Meter

The deployment of smart meter reading system greatly improves the working efficiency of public utility companies, such as groundwater network, power grid, gas network, cable network, etc., while reducing resource waste. Google’s sidewalk lab is also implementing a smart city project on the Ontario lakeside, a suburb of Toronto, Canada, to transform this inaccessible area originally mixed with power plants, underground pipeline systems, parking lots and agricultural product warehouses into the most creative Internet of things community in the world.

3. Street lamp

Intelligent street lights equipped with sensors and actuators can detect the movement of cars or pedestrians and take appropriate actions. When the activity of cars or pedestrians is found in the surrounding area, the street lamp will turn on automatically; otherwise, the street lamp will turn off by itself. Intelligent street lights can eliminate dark areas for citizens, and save energy and money without affecting the safety of the city.

4. Public safety and health

Some sensors can detect water level changes, abnormal pollution and fire. The early detection of these abnormal changes in the environment can timely warn the people in the relevant areas, remind them to close the doors and windows or leave immediately. Is the road clear? Is the bridge safe? Sensors installed in public facilities can warn of potential hazards and automatically start maintenance work.

Some sensors can sense the status of garbage cans and public toilets, or find out the public places that have become messy in time, and then inform relevant service agencies to take actions in time, such as cleaning toilets, disposing of garbage, etc. With these sensors, service organizations and service personnel are only notified when they need to. In this way, the work flow is optimized and the municipal expenses are saved.

5. Urban planning

Sensors collect and record the use of urban public facilities, such as roads, bridges, lights, and all urban public facilities, which can be the basis of municipal planning; through the actual measurement of data, and quantitative statistics of the activities of citizens and the use of public facilities, the further development of the city can be targeted planning. Sensors become data collection tools.

Through these data from all corners of the city, we can associate, process, analyze and mine the real-time municipal situation, and integrate various smart city businesses to provide new convenience for the citizens. For example, a database of lost items (such as bicycles) combined with the sensor labels on bicycles and the data perception ability on public roads can provide the recovery business of lost bicycles.

As the city grows larger and larger, there are more businesses that we can’t think of now, connecting things and people more closely.
