Device for detecting thickness of ice and snow on road

Abstract

The invention discloses a device for detecting the thickness of ice and snow on a road. The device comprises a body container with a top opening. A first temperature sensor (3) is arranged at the side surface of the top part of the body. The first temperature sensor (3) detects road surface temperature, judges whether the road surface is icy according to the temperature, and controls the on-off state of device functions. An electric heating disk (5) used for thawing the ice and snow on the road is tightly arranged below an opening of the body. A water penetrating hole (6) used for downflow of the thawed ice and snow is arranged in the electrical heating disk (5). A rotating closing device used for opening or closing the water penetrating hole (6) is tightly arranged on the bottom of the electrical heating disk (5). A flowmeter (13) used for measuring a water quantity of the thawed ice and snow is connected with the lower part of the body. The device for detecting the thickness of ice and snow on the road calculates the ice and snow thickness according to the water quantity of the thawed ice and snow. According to the invention, the road ice and snow thickness can be detected quantitatively, a reliable basis can be provided for deicing and snow removing, the manpower, the material resources and the financial resources are saved, and the pavement performance is not influenced.

Description

technical field [0001] The invention relates to an intelligent device for detecting the thickness of road ice and snow, which belongs to the technical field of sensors and measurements. Background technique [0002] In the cold winter, it is a common phenomenon that the road surface is icy and snowy. Vehicles on the icy road have to drive at a speed limit due to snow. In addition, due to the adhesion of ice and snow, the friction coefficient of the road surface is greatly reduced, which is extremely unfavorable to the safety of vehicles. The name of the utility model is: a fiber-optic icing sensor, and the patent application document with the application number 201120145252.5 proposes a fiber-optic icing sensor, but this method will produce signal saturation when the ice is thick, so it is not suitable for airports Natural icing measurements on surfaces such as runways, highways, etc. The name of the invention is: A device and method for detecting the thickness of ice and ...

Problems solved by technology

In addition, due to the adhesion of ice and snow, the friction coefficient of the road surface is greatly reduced, which is extremely unfavorable to the safety of vehicles, often leading to brake failure and loss of direction control, which has a serious impact on road safety and is extremely unfavorable to traffic safety.

The name of the utility model is: a fiber-optic icing sensor, and the patent application document with the application number 201120145252.5 proposes a fiber-optic icing sensor, but this method will produce signal saturation when the ice is thick, so it is not suitable for airports Natural icing measurements on surfaces such as runways, highways, etc.

The name of the invention is: A device and method for detecting the thickness of ice and snow. The patent application number 201210477016.2 proposes a device for obtaining the thickness of ice and snow based on an image processing device. The risk is high, and when there is black ice on the asphalt concrete road, the camera will not be able to effectively detect the thickness of the ice

The name of the invention is: a method of icing detection based on image processing, and the patent application document with application number 201110006549.8 involves a method of judging whether it is icing based on the fluidity of the water surface, which cannot provide quantitative measurement
