Vehicle exhaust remote sensing system receives more attention and reliability with its advantages of speediness, convenience and wide monitoring range, etc. It can monitor exhaust gas towards gasoline vehicles as well as diesel vehicles on the road and identify the high-emission vehicles among moving vehicles without affecting normal running. The system connects monitoring data, vehicle emission information and exhaust annual inspection data through modern communication technology to realize integrated management for vehicle emission data. For vehicle pollution prevention and management department as well as vehicle inspection institution, the establishment of the system can provide system support for general management towards the data of road exhaust pollution condition, over-emission vehicle capture and inspection data in detection field for specific vehicle.
Vehicle exhaust remote sensing device can divided into mobile remote sensing system and stationary remote sensing system. Stationary remote sensing system, which includes horizontal stationary type and vertical stationary type, can be installed on city primary roads for continuous vehicle measurement while mobile remote sensing system can decide measuring location and time, which becomes an effective complement for fixed point remote sensing measurement.
