Embodiment Construction

[0023] The method for selecting the base site for real-time remote sensing monitoring of motor vehicle exhaust in the urban road network proposed by the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] Such as figure 1 As shown, the method proposed by the present invention consists of three layers: the preparation layer, the site selection algorithm layer and the scheme decision layer.

[0025] 1. Preparation layer

[0026] First, determine the area covered by the system, that is, the monitoring range, and then investigate and collect road-related information. Definition The road network is a combination of intersections and roads, expressed mathematically as {V,E}, where V={V,V,,...,V N} represents the set of intersections, E={e 1 ,e 2 ,...,e q} is the collection of roads.

[0027] The roads in the urban road network have many characteristics, such as the width, the number of lanes, whether it is ...

Abstract

The invention discloses a real-time remote sensing monitoring base site selection method for city motor vehicle tail gas. The base site selection method comprises a preparation work layer, a site selection algorithm layer and a solution decision layer. After a monitoring area is determined and relevant information is collected, modeling is performed according to characteristics of a road, then an internal similarity of a city road network is searched based on a model and roads are classified, a representative road is selected from each classification, and a corresponding type device is selected according to a road environment, wherein each scheme runs independently. Each classification result is assessed to obtain an optimal scheme.

Description

technical field [0001] The invention relates to a base site selection method for real-time remote sensing monitoring of motor vehicle exhaust in cities, and belongs to the technical field of site selection for public facilities. Background technique [0002] The main pollutants emitted by motor vehicles include CO, CO 2 , NO, N0 2 , HC, PM, etc. These pollutants can induce asthma, bronchitis, angina pectoris, coronary heart disease and other respiratory and cardiovascular diseases. The urgency of motor vehicle pollution prevention and control has become increasingly prominent. The current detection method is widely used in the field of vehicle detection in cities, and the effect is very good. However, the offline detection method detects the exhaust gas by simulating the driving state of the vehicle, which cannot accurately reflect the exhaust emission status. [0003] "Urban road network motor vehicle exhaust real-time remote sensing monitoring system" uses a variety of...
