In order to achieve the above purpose, the utility model adopts the following technical scheme: a highway speed-limiting warning device comprises a speed-limiting indication board, an information indication board, a support, a cover, a visibility sensor, a rain and snow sensor, a wind speed sensor, a fan, a windshield wiper, a single chip microcomputer and a controller, wherein the speed-limiting indication board is fixedly connected with the information indication board, the cover is arranged outside the speed-limiting indication board and the information indication board, the cover is of a hollow structure, the fan is arranged inside the cover, the bottom of the cover is fixedly connected with the support, the support is connected with the ground, the visibility sensor, the rain and snow sensor and the wind speed sensor are arranged outside the cover, the windshield wiper is arranged on the front face of the cover and moves from top to bottom along the height direction of the cover, the visibility sensor, the rain and snow sensor and the wind speed sensor are respectively connected with, the single chip microcomputer is connected with the controller, and the controller is respectively connected with the fan and the wiper.
Furthermore, the number of the fans is multiple.
Furthermore, the bottom of the housing is provided with a vent hole.
Furthermore, the cover casing is made of transparent materials.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model provides a current speed limit warning sign can't in time change speed limit information, is covered the problem that can't play the warning effect easily by sleet. Through setting up the visibility sensor, sleet sensor and wind speed sensor, and predetermine the information in the singlechip, reduce when the visibility appears, sleet weather and wind speed increase's the condition then carries out timely adjustment to the speed limit value, and show the information sign with the information of gathering in real time, when detecting sleet weather, fan and windshield wiper begin work, provide hot-blast through the fan, melt ice and snow, eliminate fog, scrape away water through the windshield wiper, guarantee that the driver can normally receive relevant information, play the effect of timely warning.

Detailed Description
The technical solution in the embodiment of the present invention will be clearly and completely explained below with reference to the drawings in the embodiment of the present invention.
Referring to fig. 1 to explain the embodiment, the speed-limiting warning device for the expressway comprises a speed-limiting indication board 1, an information indication board 2, a support 3, a cover 4, a visibility sensor 5, a rain and snow sensor 6, a wind speed sensor 7, a fan 8, a wiper 10, a single chip microcomputer and a controller, wherein the speed-limiting indication board 1 is fixedly connected with the information indication board 2, the cover 4 is arranged outside the speed-limiting indication board 1 and the information indication board 2, the cover 4 is of a hollow structure, the fan 8 is arranged inside the cover 4, the bottom of the cover 4 is fixedly connected with the support 3, the support 3 is connected with the ground, the visibility sensor 5, the rain and snow sensor 6 and the wind speed sensor 7 are arranged outside the cover 4, the wiper 10 is arranged on the front side of the cover 4, the wiper 10 moves from top to bottom along the height direction of the cover 4, the visibility sensor 5, the single chip microcomputer is connected with the speed limit indication board 1 and the information indication board 2 respectively, the single chip microcomputer is connected with the controller, and the controller is connected with the fan 8 and the windshield wiper 10 respectively.
This embodiment is through setting up speed limit sign 1 and information sign 2 and keeping apart speed limit sign 1 and information sign 2 and external environment at the inside mode of housing 4, housing 4 is transparent material, guarantee the effective display of information, visibility sensor 5 through the outside setting of housing 4, sleet sensor 6 and wind speed sensor 7, gather visibility information in real time, sleet weather information and wind speed information, and with this information transfer to singlechip, the singlechip shows the information of gathering in real time on information sign 2, warn the driver to notice the change of relevant external condition. The single chip microcomputer judges the received information, when the visibility is reduced, the weather of rain and snow appears or the wind speed is increased, the single chip microcomputer adjusts the speed limit indication board 1 in time according to a preset numerical value, and if the visibility is judged to be more than 100 meters and less than 500 meters, the speed limit value on the speed limit indication board 1 is adjusted to be 80 km/h; and adjusting the speed limit value to 60km/h when the weather of rain and snow is judged.
