On the 19th, Yangzhuang Street in Shijingshan District newly set up a fixed-type gasoline and diesel integrated vehicle exhaust gas monitoring remote sensing device. The number plate and exhaust gas level of the passing vehicle are immediately displayed on the LED screen in front of the lane, which can make the exhaust gas not meet the standard. Shape, record and expose in real time.
Motor vehicles that have passed by, exhaust emissions are also included in the "electronic eye" monitoring. In order to strengthen the monitoring of vehicle exhaust gas, two new remote monitoring devices for exhaust gas monitoring are installed in Shijingshan District. When the vehicle passes through the monitoring area, the concentration of pollutants discharged from the exhaust gas can be detected instantaneously, and the test results are displayed on the LED electronic screen. Once the test fails, it will not pass the annual inspection.
Recently, the reporter went to Yangzhuang Street in Shijingshan District. Two white boxes were placed on both sides of the road, and an electronic camera was hung not far away. "This is specifically used to monitor the exhaust of the car. The box here is the transmitter, and the receiver is opposite. Using the optical principle to sense the distance, the pollutants such as nitrogen oxides emitted by the vehicle exhaust are monitored during the running of the car. The content, at the same time, can also record the license plate number, and the monitoring data is sent directly to the motor vehicle management center of the Municipal Environmental Protection Bureau." The relevant person in charge of the Shijingshan District Environmental Protection Bureau introduced. Going forward, an LED electronic screen is erected on the roadside. Whenever there is a vehicle passing through the monitoring area, the license plate number and the exhaust gas monitoring result are displayed in real time.
At present, the remote sensing device has been installed in two places to monitor the exhaust emissions of the passing cars. In addition to Yangzhuang Street, another Jin’an Bridge on Lanshi Road runs continuously for 24 hours. Once the center monitors the vehicle whose emission is not up to standard, the notice will be sent to the owner in the form of express delivery. After receiving the notice, the owner can go to the motor vehicle inspection field to carry out re-testing and repair the vehicle exhaust gas treatment device. If the exhaust gas treatment is still not up to standard at the annual inspection of the motor vehicle, the annual inspection will not be passed.
"This kind of exhaust gas monitoring remote sensing device can reflect the actual discharge condition of the vehicle, and can complete the monitoring during the normal running of the car. The operating condition of the car engine is more authentic when monitoring." The relevant person in charge of the Municipal Environmental Protection Bureau said that the former law enforcement personnel Most of the inspections of automobile exhausts use the method of slamming the three-legged throttle to visually measure the gray scale of the exhaust gas. Nowadays, the fixed-type remote sensing monitoring is adopted, which has the characteristics of fast monitoring, high efficiency and uninterrupted, and greatly improves the road sampling rate of the vehicle. At the same time, the entered data information is directly uploaded to the data center of the Municipal Environmental Protection Bureau, avoiding artificial fraud.
