Apparatus capable of automatically monitoring exhaust emissions of vehicles on a real-time basis and assessment method

Abstract

The invention discloses an apparatus capable of automatically monitoring exhaust emissions of vehicles on a real-time basis and an assessment method. The apparatus comprises a controller, an FPGA, a transmitting system, a receiving system, a PTZ driver, a camera, a radar speed measuring system, an RFID reader, a barometric pressure and temperature sensor, a 4G wireless transmission module and a data compensation memory table, wherein the transmitting system comprises a radio frequency driver, an acousto-optic tunable filter, an infrared light source, and a collimation system, and the receiving system comprises a first photoelectric detector, a signal processor, and a second photoelectric detector. The method improves the accuracy of exhaust gas measurement by digitally compensating for the influence of barometric pressure, ambient temperature, traffic speed, and inconsistency of the parameters of the first photoelectric detector and the second photoelectric detector on the exhaust gas measurement precision. The RFID technology is used to quickly identify traffic vehicles with exhaust emission exceeding standard and report to the traffic control department on a real-time basis, thereby improving the law enforcement efficiency of relevant departments.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring, in particular to a device and an evaluation method for automatic real-time monitoring of traffic vehicle tail gas emissions. Background technique [0002] With the rapid development of science and technology and the gradual improvement of people's living standards, the number of automobiles in large and medium-sized cities in China has increased rapidly, and the pollution of traffic vehicle exhaust has gradually become a hot spot for environmental protection departments. Accurate detection of traffic vehicle exhaust concentration is an important basis for the elimination of traffic vehicles. At present, the main traffic vehicle exhaust detection technologies include: chassis dynamometer test method, outdoor remote sensing detection method and vehicle exhaust detection method. Although the equipment cost of the chassis dynamometer test method is low, the test must be carried out u...
