Therefore, the definition should be made based on the contents throughout this specification.

As shown in FIG. 1 , a mobile fine dust measuring vehicle 3000 for measuring fine dust on the roadside according to the present invention is equipped with a vehicle-mounted roadside air pollution source measuring device 1000. The vehicle 3000 is, for example, a bus or a passenger car, and can measure the concentration of fine dust or NOx (nitrogen oxide) generated on the roadside, for example, at a bus stop or school zone, in real time.

As shown in FIG. 2, the vehicle-mounted roadside air pollutant detection device 1000 of the present invention for this purpose includes a constant velocity suction nozzle 1110, a constant temperature and humidity chamber 1100 having an air discharge unit 1120, and a complex sensor unit. 1200, an air pollutant concentration calculation unit 1300, an information transmission unit 1400, and a monitoring unit 1600;

The constant velocity suction nozzle 1110 is preferably mounted on the upper part of the vehicle, and the incoming outside air is maintained at 30 to 50 km/h. If necessary for this purpose, a flow control valve (not shown) may be further included.

The constant temperature and humidity chamber 1100 introduces roadside air to be measured through constant velocity suction nozzles 1110 mounted at the front end, and discharges the measured air through the atmospheric discharge unit 1120 formed at the rear end. The constant temperature and humidity chamber 1100 is equipped with a known constant temperature means (not shown) and constant humidity means (not shown), so that constant temperature and constant humidity can be maintained to increase the reliability of measurement.

The complex sensor unit 1200 is installed in the constant temperature and humidity chamber 1100 and detects fine dust and NOx by using air introduced through the constant velocity suction nozzle 1110 as a sample. For this purpose, a fine dust sensor and a NOx sensor are required. In addition, the complex sensor unit 1200 is equipped with a thermo-hygrometer to detect temperature and humidity in the chamber. This causes a change in temperature and humidity at the time of measurement due to the inflow of the atmosphere, and since the change in temperature and humidity causes a change in the electrical signal, this becomes a factor that lowers the reliability of the measurement, so correction for this is necessary.
