A method for managing exhaust emission in a smart city based on Internet of Things, wherein the method is implemented based on a system for managing exhaust emission in a smart city based on Internet of Things, the system includes a user platform, a service platform, a management platform, a sensor network platform and one or more object platforms, and the method is executed by the management platform, the method comprising:
- obtaining current monitoring data in a preset area collected by the one or more object platforms through the sensor network platform, wherein the sensor network platform includes one main platform of the sensor network platform and at least one sub-platform of the sensor network platform, the at least one sub-platform of the sensor network platform being in one-to-one correspondence with different object platforms, storing and processing the current monitoring data collected by the one or more object platforms, and transmitting processed information to the main platform of the sensor network platform, the main platform of the sensor network platform transmitting the processed information to the management platform, different sub-platforms of the sensor network platform corresponding to different regional locations within the preset area,
- determining vehicle information based on the current monitoring data, wherein the vehicle information includes at least one of basic vehicle information, vehicle flow information, vehicle speed information, and vehicle type distribution information,
- determining a total amount of exhaust emission in the preset area based on the vehicle information, and
- determining vehicle limit information based on the total amount of exhaust emission, and sending the vehicle limit information to the user platform through the service platform by the management platform.
