Abstract

The utility model discloses anti-fog warning equipment for freeways, particularly to the anti-fog warning equipment for freeways, which is used for distinguishing the visibility state of the freeways and for controlling the traffic state of the freeways automatically. The anti-fog warning equipment for freeways comprises a railing which is arranged on a freeway and can be started and stopped and a warning board which is fixed to the railing. Both sides of the freeway are respectively provided with a colored light source, a photoelectric sensor and a controller which is connected with the photoelectric sensor and can control the railing to start and stop correspondingly.

Description

Highway anti-fogging caution equipment

Technical field

The utility model relates to a kind of highway anti-fogging caution equipment, especially for the visibility state of differentiating the expressway, controls the highway anti-fogging caution equipment of the current state in expressway automatically.

Background technology

The development of China's expressway construction is very fast, and China's highway total kilometrage is only second to the U.S. near 20,000 kilometers at present, leaps to the second place of the world.Freeway Development has produced more and more significant effects to national economy.Build intelligent transportation system, alleviate freeway management personnel burden, improve the target that the highway efficiency of operation has become current highway development.Weather condition monitoring is an important evidence of highway science operation, and rain, snow, mist, accumulated snow, situation such as freeze all have direct influence to the operation of highway.Wherein abominable visibility has constituted serious threat to traffic safety.According to Ministry of Public Security regulation, visibility is during less than 50 meters, and relevant department can take the part or all seal the traffic control measure of highway.Highway does not reach when closing weather condition, and the greasy weather is travelled vehicle on highway according to the difference of visibility, must take the different measures of travelling, with guarantee driving safety.Therefore in the control system of highway, need a kind of equipment that can carry out the traffic management and control automatically at abominable visibility weather, and the time control highway current state, the generation that avoids traffic accident.

Summary of the invention

The purpose of this utility model is: provide a kind of and can discern abominable visibility weather automatically, and can control the highway anti-fogging caution equipment of the current state of highway automatically.

The technical solution of the utility model is:

A kind of highway anti-fogging caution equipment, include and be arranged on railing able to turn on or off on the highway and be fixed on warning sign on the railing, it is characterized in that: correspondence is provided with colored light sources and photoelectric sensor respectively in the highway both sides, and links to each other with photoelectric sensor and can control the controller that railing opens and closes.

The Fog-proof light that is connected to controller is installed on described railing.

Colored light sources is at highway opposite side direct light electric transducer, the light intensity signal of controller by judging that photoelectric sensor transmits, the visibility in the judgement highway section of detecting is when visibility counteracts the expressway driving, the railing of warning sign is put down in the controller indication, and opens Fog-proof light.

The beneficial effects of the utility model are: can detect in real time at whole highway section, and automatically, in time control the current state of highway, the traffic hazard of minimizing on highway under the sudden inclement weather, can be used as the part of express highway intelligent management, reduce the human cost of highway operation, improve the efficiency of operation of highway.

Description of drawings

Fig. 1 is a synoptic diagram of the present utility model.

Wherein, Reference numeral: 1 is controller, and 2 is photoelectric sensor, and 3 is colored light sources, and 4 is railing, and 5 is warning sign, and 6 is Fog-proof light.

Embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

As shown in Figure 1, specific embodiment of the utility model, include and be arranged on railing able to turn on or off in the vertical rod of highway limit 4 and be fixed on speed-limit warning board 5 on the railing 4, be provided with photoelectric sensor 2 on the top of vertical rod and link to each other with photoelectric sensor 2 and can control the controller 1 of railing 4 keyings, highway opposite side rod end correspondence be provided with can direct light electric transducer 2 colored light sources 3.

Another specific embodiment of the present utility model is that the Fog-proof light 6 that is connected to controller 1 also is installed on described railing 4.

The course of work of the present utility model: the photoelectric sensor 2 of the colored light sources 3 direct projection offsides of highway one side, the visibility situation has influence on photoelectric sensor 2 and receives the light intensity that offside light source 3 sends, controller 1 is judged the light intensity that photoelectric sensor 2 receives, cause light intensity variable effect controller 1 to send instruction for avoiding because the barrier that passes through stops, the 1 judgement stabilized intensity duration of controller should be longer than and just be sent instruction in 5 seconds temporarily.Sending instruction control railing 4 when controller 1 judges that visibility has influence on cruising falls, and open Fog-proof light 6, speed-limit warning board 5 on the railing and Fog-proof light 6 can make the driver see caution in distance enough far away, the generation of Reduced Speed Now to avoid traffic accident.Recover normal when visibility, photoelectric sensor 2 receiving light powers recover normal level, and controller 1 sends instruction, opens railing 4, closes Fog-proof light 6.

Claims (2)

1. a highway anti-fogging is warned equipment, include and be arranged on railing able to turn on or off on the highway (4) and be fixed on warning sign (5) on the railing (4), it is characterized in that: correspondence is provided with colored light sources (3) and photoelectric sensor (2) respectively in the highway both sides, and links to each other with photoelectric sensor (2) and can control the controller (1) that railing (4) opens and closes.
2. according to the described highway anti-fogging caution of claim 1 equipment, it is characterized in that: the Fog-proof light (6) that is connected to controller (1) is installed on described railing (4).
