A vehicle exhaust gas monitoring device and monitoring method for two-way lanes

Abstract

The invention provides an automobile exhaust gas monitoring device and a monitoring method for two-way lanes. The device includes a gas collecting mechanism, a wind speed sensor and an exhaust gas detector. The rotary lift assembly includes a connected drive part and a lift part; in the present invention, the suction pipe is arranged on the turret, and the turret is meshed and connected by the driven large gear and the driving pinion, so that the suction pipe It can be rotated within a certain range to increase the suction range of the suction pipe, and avoid the problem of large monitoring errors caused by the suction pipe only absorbing the air in a fixed direction; When the measured value of the wind speed sensor is greater than the preset wind speed threshold, the gas collecting mechanism cannot be activated, which avoids the problem that the monitoring device cannot perform effective monitoring due to the rapid flow of exhaust gas when the wind speed is too high, resulting in the monitoring device performing ineffective operation and energy waste.

Description

technical field [0001] The invention relates to the technical field of vehicle exhaust gas monitoring, in particular to a vehicle exhaust gas monitoring device and a monitoring method for two-way lanes. Background technique [0002] With the improvement of people's living standards, more and more families began to buy family cars, and the number of private cars in my country began to increase significantly, which brought serious environmental problems. The exhaust gas emitted during the driving of vehicles is seriously polluting the air. Although my country has strict control standards for vehicle exhaust emissions, however, due to the large number of vehicles, the effect is very small. Especially when the traffic volume of a certain road section is large, the air around the road will be seriously polluted by vehicle exhaust; therefore, it is necessary to monitor the road exhaust to realize the regulation of road vehicles. For example, the patent application number is: In t...

Problems solved by technology

Exhaust gas emitted by cars during driving is a serious air pollutant. Although my country has strict control standards for vehicle exhaust emissions, due to the large number of cars, the effect is minimal

Especially when the traffic flow of a certain road section is large, the air around this section of the road will be seriously polluted by vehicle exhaust; therefore, it is necessary to realize the current limiting regulation of road vehicles through monitoring the road exhaust. For example, the patent application number is In the road vehicle exhaust monitoring device and monitoring method of 201711072141.4, the exhaust gas detector is arranged on the lifting mechanism, and the monitoring device is arranged on the road surface of the vehicle. Settling on the road surface, on the other hand, because opening structures such as holes on the road surface will damage the road surface, the practicability of the above-mentioned device is not strong, and the above-mentioned device is also very easy to detect the instantaneous exhaust gas discharged from the vehicle exhaust pipe, thereby Problems that lead to large errors in test results
