Problems solved by technology

In the process of quantitative analysis of the evapotranspiration of the urban water cycle system, especially when monitoring the evapotranspiration of urban roads in the field of urban water cycle, ordinary evapotranspiration instruments (such as surface evaporators) cannot meet the requirements of complex dynamic changes. Monitoring of Pavement Evapotranspiration
At present, the monitoring of urban evapotranspiration mainly relies on the macroscopic method of remote sensing inversion. There are no relevant technical methods and corresponding technical equipment or technical facilities that can monitor the impact of artificial disturbance on urban road surface evapotranspiration, and it is impossible to microscopically monitor urban roads. Surface fogging for precise observation

Embodiment 1

[0029] This embodiment is a monitoring system for the atomization radius of the road wheel water droplets, such as figure 1 shown. This embodiment includes: a high-speed camera 5 installed on one side of the road 1, the lens of the high-speed camera is directed perpendicular to the direction of the road, and the center of the lens is at the same height as the wheel axis passing through the vehicle 2, and the same height as the lens of the high-speed camera A black backboard 3 is arranged on the other side of the road opposite to the high-speed camera, and the high-speed camera is connected to a numerical workstation 4, which is provided with a background analysis device and an atomization analysis device.

[0030] The key of this embodiment is to obtain photos through photography, and obtain the atomized radius of the water droplets through the analysis of the photos.

[0031] The road described in this embodiment may be a section of highway, or a section of road in a city. ...

Embodiment 2

[0040] This embodiment is an improvement of the first embodiment, and it is a refinement of the first embodiment about the black backplane. The black backboard described in this embodiment is provided with measurement marks.

[0041] The measurement mark can be a special ruler or an electronic ruler, which can be placed on one side of the black backboard, or it can be a grid covering the entire layout.

Embodiment 3

[0043] This embodiment is an improvement of the second embodiment, and is a refinement of the second embodiment regarding the measurement marks. The measurement mark described in this embodiment is a measuring ruler, an infrared electronic measuring ruler, such as figure 2 shown.

[0044] The ruler is an ordinary ruler 301 with a scale, and the scale should be clearly visible when shooting. Can be placed on the left or right side of the black back panel.

[0045]The infrared electronic measuring ruler is a hand-held laser infrared measuring device, which is a precise measuring tool. It uses the principle of non-diffusion when infrared rays propagate to measure length and size. This embodiment measures the size of the atomization.

Abstract

The invention relates to a system for monitoring a road wheel water drop atomization radius. The system comprises a high-speed camera installed on a side of a road. The lens of the high-speed camera points to the direction vertical to the road. The center of the lens and the axis of the wheels of a passing vehicle are at the same height. A black backboard is disposed on the other side, opposite to the high-speed camera, of the road. The high-speed camera is connected with a numerical value workstation in which a background analysis device and an atomization analysis device are disposed. The system, by comparing high-resolution pictures of rear wheel water drop atomization when the rear wheels pass by a rainwater road, analyzes the high-resolution pictures captured by the high-speed camera and removes a background value. The atomization radius of the water drop is reckoned by comparing the transparency of the pictures. Further, the system fully takes account of an influence of a city road surface traffic flow atomization effect on city evapotranspiration, solves a monitoring problem of the city evapotranspiration under artificial interference, and fills in a technical blank in accurate wheel atomization radius monitoring.

Description

technical field [0001] The invention relates to a monitoring system and method for the atomization radius of water drops on road wheels, which is an environmental protection monitoring system and method for water resources, a hydrological monitoring system and method, and a system and method suitable for monitoring urban road surfaces in the field of urban water circulation. Microscopic evapotranspiration monitoring system and method. Background technique [0002] Human activities in cities have had a great impact on the hydrological cycle process, and the main links of the hydrological cycle, such as evaporation, infiltration, surface runoff, and underground runoff, have all changed under the influence of human activities. In recent years, urban water consumption has shown a trend of high intensity and rapid growth, which is of great significance to the monitoring of urban evapotranspiration and other water consumption. Due to the existence of a large number of roads in th...
