Embodiment Construction

[0012] The present invention is designed based on the Ministry of Transport's construction science and technology project "Research on Safety Guarantee Technology for Road Construction and Operation in Wuling Mountain Area" (2014318785090).

[0013] A highway early warning system based on rain gauges includes several rain gauges arranged along the highway, a display screen and a control subsystem used in conjunction with the rain gauges. The rain gauge is arranged at intervals along the expressway for monitoring the rainfall information at this place; the control system obtains the safe driving speed of the vehicle based on the rainfall information; The safe driving speed calculated by the obtained rainfall information. A training subsystem and a speed acquisition subsystem are set in the control system: the training subsystem is based on different rainfall information, the road surface structure where the rain gauge is located, and different tire structures to train and obtai...

Abstract

The invention provides a highway early warning system based on pluviometers, and the system comprises a plurality of pluviometers which are arranged along a road, display screens cooperating with the pluviometers, and control subsystems cooperating with the pluviometers. The pluviometers are set at certain intervals along a highway, and are used for monitoring the rainfall information of each place. The control systems are used for obtaining the safety running speeds of the vehicles based on the rainfall information. Each two display screens serve as one group, and display the safety running speed calculated through the rainfall information obtained by one pluviometer. Each group of display screens are disposed on opposite highways, and are respectively located at the downstream sections of the corresponding pluviometers. The system can automatically obtains the safety running speeds of vehicles under the rainfall according to the size of the rainfall.

Description

technical field [0001] The invention relates to a traffic early warning technology, in particular to a rain gauge-based expressway early warning system. Background technique [0002] In recent years, with the rapid development of the economy, the mileage of expressways in my country has also been continuously extended, and the comprehensive benefits of expressways being convenient, fast, safe and smooth are constantly emerging. However, due to the expressway's fast speed, large flow rate and its own fully enclosed characteristics, once the expressway encounters special weather with low visibility, especially sudden and random fog conditions, traffic accidents are extremely prone to occur. The reduction of visibility on highways caused by weather factors such as heavy fog, rain and snow, and sandstorms has become the main cause of traffic accidents on highways, and has caused huge losses in social economy and people's lives and properties. Therefore, the design and developme...
