Problems solved by technology
This technical solution focuses on monitoring the exhaust emission of a single vehicle, focusing on the supervision of vehicle exhaust. It fails to correlate the current operating status of the monitored motor vehicle with the actual pollution level of the atmosphere in real time, and cannot accurately monitor the exhaust gas generated during the operation of the vehicle. The degree of actual impact on the atmospheric environment, it is impossible to accurately control and induce the operation of the vehicle

Embodiment Construction
[0039] This embodiment provides a system that uses number plate recognition technology to monitor the impact of motor vehicles on the environment, and its principle block diagram is as follows figure 1 As shown, it includes a license plate recognition terminal 6, which is arranged at the entrance and exit of the inspected road section, and recognizes the license plate of the vehicle entering and leaving the vehicle in real time; the sulfur dioxide sampling module 5 is arranged at the inspected road section, Collect atmospheric samples within the scope of the inspected road section; the vehicle occupies the road time processing module 4, receives the number plate information sent by the number plate recognition terminal 6, and obtains the time when the vehicle with the same number plate enters the inspected road section and the time of driving out of the inspected road section to further obtain the time t it takes to pass through the inspected road section ci , where i is the num...

The invention relates to a system and a method for monitoring influences for a motor vehicle on environment by using a license plate recognition technology. The system is composed of a data processing module, a sampling control module, a sulfur dioxide sampling processing module, a vehicle-occupied time processing module, a sulfur dioxide sampling module and a license plate recognition terminal. A vehicle's running state is monitored and sampled for analysis by using the license plate recognition terminal and the vehicle-occupied time processing module; atmospheric pollution degree is sampled and analyzed by using the sulfur dioxide sampling module and the sulfur dioxide sampling processing module; synchronous control of the sulfur dioxide sampling module and the vehicle-occupied time processing module is realized by the sampling control module; a relation curve of the vehicle's running state and the atmospheric pollution degree is displayed in a figure or table mode by the data processing module. A real influence degree to the atmospheric environment caused by current exhausts of the running motor vehicle can be quantitatively obtained.
Description
technical field [0001] The invention belongs to the field of environmental science and technology, and in particular relates to a system and method for monitoring the actual impact of tail gas emitted by motor vehicles on the atmospheric environment by using number plate recognition technology. Background technique [0002] With the rapid economic development, the air pollution in cities has increased. Air pollution mainly comes from human life and production activities. There are three main sources of man-made pollution in the atmosphere, including domestic pollution sources, industrial pollution sources, and transportation pollution sources. There are many factors that cause severe atmospheric pollution. People have reached a consensus that the exhaust gas produced by motor vehicles is the main cause of serious air pollution exceeding the standard. How to quantitatively analyze the degree of influence of motor vehicle exhaust on air pollution in a certain area is the focu...
