The telemetry car debuted at the Central Expo for 1 second

With the introduction of the environmental protection index PM2.5, the detection and remediation of pollutants emitted by motor vehicle exhausts is imminent. At the “China Central Expo” held at the Shanghai New International Expo Center in the past few days, remote-sensing vehicles that can detect whether or not the vehicle’s exhaust emissions exceed the standard are not noticed in 1 second without intercepting vehicles. At present, the city's environmental protection department has introduced one vehicle and placed it in the mouth of the Shanghai Railway. The follow-up of five vehicles will also be gradually “posted”.

As long as a set of half-meter-high laser remote sensing equipment is placed on both sides of the road, information on the license plate number and pollutant concentration of the discharged gas will be immediately ingested after the normal driving vehicle passes, and will be transmitted to the place about 3 meters away from the equipment. Laser remote sensing vehicle. The license plate number displayed on the big screen of the car keeps on refreshing, and the green “qualified”, the red “exceeded”, and the yellow “yellow label” change along with it. It is reported that the detection width of this telemetry system equipment can reach 38 meters. Therefore, even if a wide-area road with 4 lanes is used, the motor vehicles passing are all within the scope of monitoring and control.
