Abstract
The utility model discloses a low-speed vehicle merging alarm for highway, wherein the alarm is arranged at a junction part between the highway and a branched road or service area outlet. The low-speed vehicle merging alarm comprises a vehicle sensor, a single-chip microcomputer and an alarm. The alarm is a display device or an alarm lamp. The vehicle sensor is arranged at a part which is separated from the junction part for several ten meters on the branched road or separated from the outlet for several ten meters in the service area. The alarm is arranged at a part which is separated from the branched part for several ten hundred meters in vehicle driving direction of the highway. The single-chip microcomputer is connected with the vehicle sensor and the alarm respectively. Through the low-speed vehicle merging alarm provided by the utility model, the condition of the low-speed vehicle which is driven out from the junction part or the outlet of the service area can be notified in advance, thereby ensuring sufficient time for the vehicle which is driven on the highway for predetermining, taking dodging measure and preventing traffic accident.
Description
Technical field
The utility model is specifically related to a kind of expressway slow-moving vehicle incision alarm device.
Background technology
When expressway normal vehicle operation, there is suddenly car to cut from by-path low speed.Often make human pilot panic, deal with improperly traffic hazard very easily occurs.As shown in Figure 1, A car is sailed in runway normal row with hundred kilometers of speed of a motor vehicle, and C car is overtaken other vehicles in fast with the speed of a motor vehicle that exceedes hundred kilometers, and B car is from by-path and the incision of service area outlet low speed.B car walks at 2 from 1 and enters runway.Because of angle reason, in side mirror, cannot see anxious the speeding of runway and next A car.Now, as too late in the brake of A car, accident will occur immediately.This situation is even more serious at misty rain and night.All people who drives in expressway often run into, and feel danger close.The major traffic accidents of this character can be looked into conveniently on the net.Wrap on August 26th, 2012 luxuriant high speed once dead 36 people of special major traffic accidents be exactly obvious example.This class example is too numerous to mention.
Summary of the invention
The purpose of this utility model is the defect existing in prior art in order to solve, and a kind of device that can effectively carry out alarm to low speed incision vehicle condition at highway is provided.
To achieve these goals, the utility model provides a kind of expressway slow-moving vehicle incision alarm device, and this alarm device is located at fork place or the service area exit that highway is connected with by-path, comprises detector, single-chip microcomputer, attention device; Attention device is display or warning lamp; Detector is located in a track pitch fork position of meters away or service area ten meters of apart from exit; Attention device is located at highway garage direction apart from hundreds of meters of of fork; Single-chip microcomputer is connected with detector, attention device respectively.
In the time that attention device adopts warning lamp, be the lamp of two different colours, comprise green current lamp and yellow alarm lamp.
When attention device adopts when display, be LED display, comprise that speed of a motor vehicle light board and car count light board.Detector comprises that speed of a motor vehicle inductor and car count collector; Speed of a motor vehicle inductor is counted collector with car and is connected with single-chip microcomputer respectively.
Wherein, detector is located in a track pitch fork or service area apart from 20 to 50 meters of of outlet; Attention device is located at highway garage direction apart from 100 to 200 meters of of fork.
Detector also comprises optical inductor and humidity sensor; Optical inductor is connected with single-chip microcomputer respectively with humidity sensor.
The utility model has the following advantages compared to existing technology: utilize detector to respond to slow-moving vehicle, by attention device, vehicles running on expressway is carried out to warning in advance, make and dodging or deceleration measure, thereby it is dangerous greatly to reduce driving, the generation trying to forestall traffic accidents.Utilize optical inductor and humidity sensor sensing light intensity and misty rain weather to judge the displaying time of LED display simultaneously, in case of inclement weather or the poor situation of light should show ahead of time than fine day and the stronger situation of light, slow-moving vehicle quantity is informed in advance.Utilize the utility model alarm device effectively to inform in advance slow-moving vehicle situation, thereby judge in advance to moving traffic with the sufficient time, make the measure of dodging, the generation trying to forestall traffic accidents.

Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
As shown in Figures 2 and 3, the utility model alarm device comprises power supply, single-chip microcomputer, detector 3 and attention device 4.Power supply powers to respectively single-chip microcomputer, detector 3 and attention device 4.Single-chip microcomputer adopts (80C51 series waits), controls detector 3 and attention device 4.Detector 3 is arranged in a track pitch fork or service area apart from 20 to 50 meters of of outlet, comprises that car counts collector, speed of a motor vehicle inductor, light intensity sensor and humidity sensor.Wherein car is counted collector can to adopt patent publication No. is that the patent that the city expressway flow motor real-time acquisition device of CN102982685A carries out automobile quantity gathers car number by REID.Speed of a motor vehicle inductor can adopt existing expressway speed pick-up unit.Attention device is established (it is large especially that line space seems) and (can be adjusted according to the speed limit of different highways) apart from hundreds of meters of of fork in highway garage direction, adopt warning lamp and LED light board, comprise that pass through lamp, gold-tinted stand by lamp, gold-tinted car of green glow count board, gold-tinted speed of a motor vehicle board.
When use, first utilize optical inductor induction light power, utilize humidity sensor induced environment humidity, and intensity signal and humidity information are passed to single-chip microcomputer.Utilize car to count the instantaneous vehicle passing through of collector induction how many, quantity information is passed to single-chip microcomputer, utilize the induction of speed of a motor vehicle inductor in time by the speed of a motor vehicle of vehicle, speed information is passed to single-chip microcomputer; Single-chip microcomputer judges the displaying time of attention device by the intensity signal received and humidity information.When fine weather, single-chip microcomputer postpones a period of time (or in real time) and vehicle fleet size information and speed information are presented to gold-tinted car count on board and gold-tinted speed of a motor vehicle board, and gold-tinted stand by lamp is bright; If pass through without car, the current lamp of green glow is bright.Optical inductor can judge daytime and night, fine day and cloudy day, whether have haze etc. these affect the factor of driver's sight line by light intensity, humidity sensor can judge the factors such as mist, rainfall size, snowfall size, both combine, and can judge pre-warning time (being the single-chip machine information transmission delay time).If fine day is the daytime without haze without mist, driver's sight line is better, now pre-warning time can be shorter, thereby without allowing the driver of high speed traveling affect follow-up Vehicle Driving Cycle in the too early reduction of speed of long tense situation, carry out early warning in the time being about to approach.If cloudy, haze sky, the situation that mist is larger, or when the weather such as sleet, sight line and required time and the distance of emergency brake that can affect to a great extent the driver, now need to lengthen pre-warning time, gives enough running times of driver of the vehicle of running at high speed.When single-chip microcomputer is when being judged as night, cloudy day, haze weather, sleety weather to intensity signal and humidity information, postpone the short period or in real time vehicle fleet size information and speed information are presented to gold-tinted car to count on board and gold-tinted speed of a motor vehicle board, and gold-tinted stand by lamp is bright.
