Scenic area road traffic pollution early-warning device based on remote sensing technique and scenic area road traffic pollution early-warning method based on remote sensing technique

Abstract

The invention discloses a scenic area road traffic pollution early-warning device based on a remote sensing technique. Atmospheric laser measurement systems are arranged at measuring points of three to five commanding heights, and all of the atmospheric laser measurement systems are connected to a server; a monitoring result device which is used for detecting the concentration of pollutants of a scenic area road traffic environment air roadside fixed routine monitoring station is connected to the server; a monitoring device of a scenic area combined environment air fixed routine monitoring station is connected to the server; in consideration of various advantages and disadvantages of a current area environment monitoring platform, according to the geographic feature of 'on three sides are cloud-capped hills, on one the busy town' of a West Lake scenic area, NO2 and other chemical substances which are mainly generated by road traffic in the scenic area are monitored in real time by constructing an atmospheric remote sensing and remote measuring platform at the commanding heights around the West Lake.

Description

technical field [0001] The invention belongs to the cross field of environmental science and technology, public safety and disaster prevention and mitigation, and relates to a road traffic pollution early warning device and method for scenic spots based on remote sensing technology. Background technique [0002] With the improvement of economic conditions, the opportunities for Chinese people to travel during holidays have been greatly improved. Hangzhou West Lake Scenic Area, a world natural and cultural heritage of "heaven above and Suzhou and Hangzhou below", is attracting more and more visitors from home and abroad. However, the access and passage roads of the West Lake scenic spot are mostly positioned and designed according to the city's secondary arterial roads or even branch roads. With the continuous increase of tourist traffic, the dilemma of "difficult to drive and difficult to park" often occurs when entering and exiting the West Lake. The traffic jam during the...

Problems solved by technology

Although the actual measurement method is the most reliable method, a network is formed by establishing multiple long-term monitoring stations in the region. At present, the N0 of most stations 2 , PM and other chemical substances and gases are ground-based point instruments. For example, there are several such stations in the West Lake Scenic Area, but limited by personnel, investment and operating costs, the ground stations and concentration observation data, Especially from the perspective of 3-dimensional spatial distribution, the data is very limited, and the spatial distribution information of the atmosphere cannot be obtained, which generally leads to small coverage and poor timeliness

At present, the best spatial distribution data is traditionally obtained and realized through the remote sensing technology of balloon airship aircraft aviation and satellite aerospace airborne instruments, but its operation cost is higher, and the time and spatial resolution of the obtained data are poor
