Abstract
The utility model discloses a sound warning device for vehicles coming in the opposite direction in poor sight distance road sections. The device can detect vehicles in the opposite direction in poor sight distance road sections to warn vehicles to slow down, the device collects sound information of vehicles in the opposite direction through an audio sensor, processes sound signals collected by the sensor by using a single chip microcomputer, and reminds drivers of the vehicles in the opposite direction and to drive slowly and cautiously through a speaker and a warning light when detecting the vehicles in the opposite direction. A solar power supply system is designed for being used in mountain areas and highways with poor power supply sections by the system. The warning device has the advantages of being practical, safe, reliable, low in price, stable in performance, low in energy consumption, convenient to install, and capable of being used in various section modes and weather conditions.
Description
Technical field
The utility model relates to a kind of traffic safety intelligent apparatus, the bad highway section of the particularly a kind of sighting distance subtend acoustics warning alarm set of sending a car.
Background technology
Traffic hazard on the highway in China occurs in one mostly to Class III highway, and accident number of times, the dead and wounded number that bump against positive collision, side are all very high.In the traffic hazard that takes place in recent years, the traffic hazard that the dead crowd of crowd hinders receives social concerns especially, and these accident major parts occur in mountain area, the strategically located and difficult of access location of trackside, and whether road safety, the direct relation people masses' life and property safety.Wherein, it is the major reason that causes this situation that highway section bad visibility, highway safety and handling facility do not match or do not bring into play due effect.
The traffic safety facilities that improves the bad highway sections of sighting distance such as sharp turn, abrupt slope at present mainly contains pick-up units such as convex mirror, sight line inducing sign, shunting graticule and video, microwave, electromagnetism, coil; And these several kinds of MP all have the shortcoming that is difficult to overcome; Convex mirror can only be fit to daytime planar curve path use and visible angle limited; Minute surface is influenced by dust, rainwater etc. easily to cause that visual range shortens; Should not be provided with at level crossing, shortcoming such as can not use in the bad highway section of sighting distance that vertical curve causes; Pick-up units such as video, microwave, electromagnetism, coil are because of costing an arm and a leg and needing a large amount of electric energy, and the unsuitable large tracts of land of the road that especially category of roads is lower in western part is promoted; Enforcements such as sight line inducing sign, shunting graticule can not remind subtend to send a car, and should not use separately, need to cooperate the common competence exertion better effects of using of other devices.
Summary of the invention
The fundamental purpose of the utility model provides a kind ofly can install the automatic warning alarm set of reminding opposed vehicle to send a car in the bad highway section of sighting distance.
In order to realize above-mentioned technical assignment: the bad highway section of a kind of sighting distance of the technical scheme that the utility model the adopted subtend acoustics warning alarm set of sending a car; Comprise audio detection sensor, prime amplifier, data collecting card, single-chip microcomputer, electronic display and loudspeaker, the acoustic information that the device of the utility model arrives through the audio sensor collection, the voice signal that the single-chip microcomputer processes sensor collects; When detecting the bad highway section of sighting distance subtend and send a car; Device can remind subtend driver subtend to have car to arrive through loudspeaker and electronics display board, reminds the driver to note dodging, and the utility model is through the solar panels generating; Utilize the battery electric power storage, through storage battery power supply.
Said audio detection sensor adopts condenser microphone, is responsible for the voice signal of vehicle is converted into electric signal.Said prime amplifier adopts and the supporting charge amplifier of electric charge microphone, is used to amplify the voice signal that collects.Said data collecting card adopts the AD8301 data collecting card, is responsible for electric signal is converted into digital signal.
Said single-chip microcomputer is responsible for processing digital signal, and whether differentiate highway section, the place ahead has vehicle to sail, and said loudspeaker and warning lamp are used to remind opposed vehicle to detect subtend has vehicle to sail, and please notes and goes slowly.
The utility model based on the audio detection Design Theory the bad highway section of a kind of sighting distance subtend warning alarm set of sending a car; Can overcome whole shortcomings of above traffic safety facilities, have the advantage that practicality, safe, reliable, cheap, stable performance, energy consumption are low, easy for installation, can under various form of fractures and various weather, use.
Description of drawings
The structural representation of Fig. 1 utility model.
The audio sensor outer cover installation diagram of Fig. 2 the utility model.
Below in conjunction with accompanying drawing the particular content of the utility model is done further explain.
Embodiment
As shown in Figure 1, whether the subtend acoustics warning alarm set of sending a car in the bad highway section of a kind of sighting distance can send a car through the bad highway section of audio frequency sighting distance subtend, and through warning lamp and loudspeaker prompting driver.It comprises audio detection sensor, prime amplifier, data collecting card, single-chip microcomputer, warning lamp and loudspeaker; The audio detection sensor links to each other with prime amplifier, data collecting card, single-chip microcomputer input end successively; The single-chip microcomputer output terminal also links to each other with loudspeaker with electronic display respectively, and prime amplifier also links to each other with solar cell.
The bad highway section of the sighting distance of the utility model subtend acoustics warning alarm set of sending a car; At first pass through the sound signal of audio detection device collection vehicle; Through the amplifier amplifying signal, convert into and can be sent to single-chip microcomputer then by the single-chip microcomputer identified signal through capture card; The signal that utilizes single-chip microcomputer analysis collection then judges whether subtend has vehicle to sail; If have, then report to the police through warning lamp and loudspeaker.
As shown in Figure 2, audio sensor need be installed outer cover when installing, and can only collect the vehicle sounds of a direction to guarantee sensor, and can not disturbed by the sound of vehicle in the same way.
