Abstract

The invention provides a high-precision non-contact type road surface temperature measuring device. The device includes an infrared optical signal detecting module, a signal modulating module and a signal collecting and processing module. The infrared optical signal detecting module realizes optical signal detection and waveband selection. The signal modulating module realizes amplification and modulation of collected signals. The signal collecting and processing module realizes functions of analog-digital conversion, temperature inversion and the like. The invention also provides a measuring method of the high-precision non-contact type road surface temperature measuring device. According to the invention, a double-detector measuring system is adopted. One of the detectors detects infrared radiation caused by temperature of the measuring device itself. The influence from the temperature of the measuring device itself is deducted when measuring the infrared radiation of a target road surface and the infrared radiation amount of the target road surface is obtained accurately, so that accurate inversion of target road surface temperature is realized and accuracy and practicality of the measuring device are improved effectively.

Description

technical field [0001] The invention relates to the technical field of road traffic safety meteorological element detection, in particular to a high-precision non-contact road surface temperature measuring device and a measuring method thereof. Background technique [0002] With the development of road traffic and the rapid increase of vehicles, the impact of road weather conditions on transportation is becoming more and more extensive. Bad road weather conditions have caused more traffic accidents and even threatened people's lives and properties. [0003] Pavement temperature is an important indicator of road weather conditions. As the temperature changes, so does the material strength and stiffness of the pavement. Due to the poor thermal conductivity of pavement materials, when the temperature changes, the surface temperature of the structure changes rapidly, and the internal temperature of the structure changes very little. Each part is in a different temperature state...
