Road icing safety early warning device and early warning method

Abstract

The invention provides a road icing safety early warning device and early warning method. The early warning device comprises a monitoring system and an early warning system. The monitoring system mainly comprises an icing sensor, an instrument shelter, an anemorumbometer and a control box. The early warning system is used for feeding back the road icing situation to the road management department in real time or performing early warning in real time through roadside warning information and mainly comprises a data acquisition system, a wireless module and an early warning terminal. The early warning method comprises the following steps that step one, the ice thickness calibration test is performed, and the corresponding relation between the icing thickness, the icing rate and the ambient temperature is obtained through simulation; step two, the indoor simulation experiment is performed to verify the sensitivity and the reliability of the icing sensor; and step three, the field test is performed so that whether the road icing safety early warning device can reliably perform multi-parameter acquisition can be ensured and safety early warning of the road icing situation can be timely performed. The road icing thickness and the icing rate can be acquired in real time and the road icing situation can be timely fed back to the road management department.

Description

technical field [0001] The invention relates to the field of road safety, in particular to a road icing safety early warning device and an early warning method. Background technique [0002] So far, countries do not have a relatively reliable device to efficiently and accurately carry out road icing safety warnings. At present, in most areas, people go to the road to observe whether the road is icy, and then make a safety warning. Although this approach is intuitive and effective, for a huge road network, manual early warning is time-consuming and laborious. In some areas where the traffic department is not strictly supervised, it is often not until the traffic accident occurs that the seriousness of the problem is realized. Therefore, real-time monitoring and accurate early warning of icy roads have become an urgent need to ensure the safety of life and property and avoid traffic jams. Contents of the invention [0003] The technical problem to be solved by the present ...
