Description
Technical field
The utility model discloses a kind of integrated self-adaptive intelligent traffic warning board, relate to traffic safety facilities technical field.
Background technology
In recent years, the development of China's expressway construction is very fast.Since building up China's Article 1 highway from 1988, to the end of the year 2010, China's highway mileage open to traffic will reach 7. 3 ten thousand km.According to " national expressway network planning ", China accelerates the construction of national expressway network main framing hammer and tongs, to the year two thousand twenty, substantially builds up national expressway network.When the time comes, the China Expressway total kilometrage that is open to traffic will reach 100,000 km.New road network is made up of, referred to as " 7918 " net 7 capital radioactive ray, 9 north and south vertical lines and 18 thing x wires.
Along with the develop rapidly of transportation, weather condition is also increasing on the impact of expressway safety, and atrocious weather condition brings huge harm to the traffic safety of highway, even threatens the security of the lives and property of people.According to statistics, in ice and snow road, ponding road surface and normal dry pavement 3 kinds of situations, the ratio of probability that traffic hazard occurs is 4. 2: 1. 6: 1, even even more serious in this phenomenon of cold district.So Weather information promptly and accurately becomes the key components that freeway management department ensures traffic safety.
And China's freeway traffic weather monitoring system research and apply work is started late, traffic weather information is also mainly derived from the checkout facilities such as the weather station of Highways ', the main body frame of this system is substantially based on the monitoring of traditional meteorological key element, and visiometer and pavement state sensor great majority still depend on import equipment.Highway division and Meteorological Field Cooperation undertighten, thus freeway management department to highway because weather environment provides the ability of professional service also very limited, existing safety warning-panel or be fixing poster; Be the information (as shown in the figure) of long-range artificial input, these can not provide real-time security warning information to human pilot timely and accurately.
The countries such as Sweden, Britain, Finland are the countries carrying out the research of freeway traffic weather monitoring system in the world the earliest, and the application work of many initiatives is also pushed to all over the world gradually from these countries.When early 1980s, there is " ice detection " system in highway communication, system comprises weather station, some outfields, weather data is obtained by the various sensors of weather station, workstation " poll " meteorological sensor of highway division, and utilize the connection of intercomputer real time data to be transmitted to multiple place, enable to close on the progress situation of change that department monitors weather conditions.Improve operating service and the security level of road.
Though current highway has some traffic warning boards and weather monitoring station, both degrees of association are not high.The existing traffic warning board of highway, can only show fixing caution slogan mostly and real road situation does not have actual relationship, does not thus reach actual technical role; And the information of existing a small amount of weather monitoring station could will be issued by control center in variable information board, one carrys out information can not be timely, and relevant information will enter multiple links such as front-end collection, transmission and background process; Two carry out whole system involves great expense and can not popularize, and cannot meet the demand of expressway traffic safety management.
