Motor vehicle pollution discharge supervision system and method

Abstract

The invention belongs to the field of environmental protection monitoring, and particularly relates to a high-pollution-discharge motor vehicle comprehensive supervision system and method. According to the high-pollution-discharge motor vehicle comprehensive supervision method, pollution index calculation with unified indexes is carried out on all recorded vehicles, and the motor vehicles with a high pollution index are vehicles which discharge more tail gas and need to be rectified. The supervision system is derived from four aspects of evaluation of different weights: environmental measurement, remote measurement, black smoke and OBD. In the system, the contribution degrees of environmental measurement, remote measurement, black smoke and OBD to the comprehensive supervision system are analyzed and researched by experts to obtain the weights, the four weights are multiplied by the scores obtained by a motor vehicle in the environmental measurement, remote measurement, black smoke andOBD respectively, and then the products are added to obtain the pollution index of the motor vehicle.

Description

technical field [0001] The invention belongs to the field of environmental monitoring, and in particular relates to a comprehensive monitoring system and method for high-pollution motor vehicles. Background technique [0002] As one of the main sources of air pollution, motor vehicle exhaust contains a large number of harmful substances, including carbon monoxide, nitrogen oxides, hydrocarbons and solid suspended particles. With the rapid development of my country's economy, the number of domestic motor vehicles is also increasing, which is an important reason for the frequent occurrence of smog in major cities across the country in recent years. The supervision of high-emission motor vehicles has always been the focus of environmental protection work. [0003] At present, the supervision methods adopted by the supervision department include environmental protection inspection, telemetry, smoky car capture, OBD vehicle terminal monitoring, etc., but these methods have diffe...

AI Technical Summary

Problems solved by technology

[0004] 1. The environmental protection inspection does not consider the actual situation of the motor vehicle on the road, such as load, acceleration, etc., and the measured data may deviate from the actual situation

[0005] 2. The telemetry method is greatly affected by meteorological conditions, and the data measured under different weather conditions have large deviations, which cannot be used as a basis for law enforcement

[0006] 3. The smoky vehicle capture system can only capture motor vehicles passing through fixed roads, and vehicles that do not pass through roads equipped with smoky vehicle capture system cannot be detected

[0007] 4. The OBD vehicle-mounted terminal monitoring system does not cover all motor vehicles, and motor vehicles that are not equipped with OBD vehicle-mounted terminal systems cannot be monitored
