Contact type road condition detecting system

Abstract

The invention discloses a contact type road condition detecting system which comprises two light sources, a detector and a temperature sensor. The two light sources, the detector and the temperature sensor are integrated into a machine seat, the two light sources can respectively emit light, and the detector is used for receiving reflection light emitted by the two light sources and scattered by a road surface. The contact type road condition detecting system further comprises a positive electrode and a negative electrode which are arranged beside the temperature sensor, the positive electrode and the negative electrode are respectively installed in the machine seat, one end of the positive electrode and one end of the negative electrode are both exposed out of the road surface, and the light sources, the detector, the temperature sensor, the positive electrode and the negative electrode are all connected with a microprocessor. The contact type road condition detecting system is of a structure of the two light sources and one single detector, is simple and compact, is convenient to dismount, maintain, detect and update, and reduces production cost. The positive electrode and the negative electrode are used for detecting the water salinity on the road surface. The temperature sensor arranged beside the electrodes can measure environmental temperature and can serve as environmental monitoring for conductivity measurement to carry out temperature compensation. Thus, salinity measurement is more accurate, and functions are more comprehensive.

Description

[0001] Technical field [0002] The invention belongs to the technical field of road condition detection equipment, and relates to an automatic detection device for contact road conditions such as rain, snow, and ice. Background technique [0003] Under unfavorable weather such as rain, snow, and fog, bad road conditions such as low visibility, icing (water accumulation) and slipping on the road may occur, which contains hidden dangers of traffic accidents and often leads to major safety accidents. It is necessary to adopt intelligent transportation technology and methods. Early warning and control of adverse weather road conditions to ensure the safety of highway driving in adverse weather. [0004] The collection of unfavorable weather and road condition information is the basis of early warning and control. Commonly used road traffic and road condition detection methods are generally manual or sensor equipment detection. The manual detection error is large, and it is easy to mis...

AI Technical Summary

Problems solved by technology

Manual detection has large errors and is easy to miss; the use and maintenance of road sensors are inconvenient and expensive

There are generally problems such as incomplete road condition monitoring equipment along the domestic expressways, detection density and elements that do not meet the requirements.
