The utility model has the beneficial effects that when a driver is fatigued and one side of the motor vehicle crosses the separation line on a road or the motor vehicle vibrates to the left and to the right to cross the separation line on the road, the device can emit the sound to wake the driver up to correct the driving direction, thereby reducing the occurrence of overturn accident.
Description
Technical field
The utility model belongs to the motor vehicle safe drive warning device, relates in particular to the alarm set that a kind of motor vehicle is crossed over traffic lane separating line.
Background technology
At present, transport by road has occupied the suitable share of internal transportation total amount, and the traffic hazard of Yin Faing is also corresponding thus increases.Especially highway overturn accident, wherein most accidents all are to cause owing to driver tired driving causes distraction.Prevent that the driver from having become problem demanding prompt solution because of the overturn accident that fatigue driving causes.At present, motor vehicle driving indoor still do not have the safe alarm set prevent driver tired driving is installed.
The utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and provide a kind of motor vehicle to cross over the alarm set of traffic lane separating line, can send the sound when the lines on the vehicle crossing highway wakes up with a start the driver and in time revises travel direction, to reduce the overturn accident that causes because of fatigue driving, reduce the people's lives and property loss.
The utility model for achieving the above object, by the following technical solutions: a kind of motor vehicle is crossed over the alarm set of traffic lane separating line, it is characterized in that: alarm set mainly is made of light emitting devices, optical transmission circuit, light receiving element and reception amplifying circuit, described optical transmission circuit is connected with the light emitting devices that is installed in the motor-vehicle chassis left and right sides, described optical transmission circuit is connected with the reception amplifying circuit with gating circuit, and gating circuit is connected with sound driving circuit and loudspeaker; The described light receiving element that is installed in the motor-vehicle chassis left and right sides is connected with the reception amplifying circuit, receiving amplifying circuit is connected with monostable trigger with voltage identification successively, monostable trigger is connected with above-mentioned gating circuit, and described each element circuit is connected with the output terminal of supply convertor.
Described gating circuit is connected with modulator.
The input end of described supply convertor is connected with switch, and the other end of switch is connected with power sources of motor vehicle.
The utility model beneficial effect: when lines on the one-sided crossing highway of motor vehicle of driver tired driving or distraction driving or the lines on the crossing highway of vacillating now to the left, now to the right, this device that is installed in pilothouse can send the sound and wake up with a start the driver and in time revise travel direction, to reduce the overturn accident that causes because of fatigue driving, reduce the people's lives and property loss.
Description of drawings
Fig. 1 is that circuit of the present utility model connects block diagram.
Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing and preferred embodiment.
See accompanying drawing for details, a kind of motor vehicle is crossed over the alarm set of traffic lane separating line, and the output signal of optical transmission circuit 1 is connected with the light emitting devices 9,10 that is installed in the motor-vehicle chassis left and right sides; The control signal of optical transmission circuit 1 is connected with gating circuit 6 and reception amplifying circuit 2; The light receiving element 11,12 that is installed in the motor-vehicle chassis left and right sides equally is connected with reception amplifying circuit 2; Receiving amplifying circuit 2 is connected with voltage identification 3; Voltage identification 3 is connected with monostable trigger 4; Monostable trigger 4 is connected with gating circuit 6; Gating circuit 6 is connected with sound driving circuit 7; Sound driving circuit 7 is connected with loudspeaker 13; The input end of supply convertor 8 is connected with switch 14; The other end of switch 14 is connected with power sources of motor vehicle; The output terminal of supply convertor 8 connects each element circuit.Described gating circuit is connected with modulator 5.
Principle of work: when connecting switch 14, radiating circuit 1 drive installation is sent light signal at the light emitting devices 9,10 of the motor-vehicle chassis left and right sides.When vehicle was not crossed over lines, it was very weak to be installed in the road surface light reflected signal that the light receiving element 10,11 of the motor-vehicle chassis left and right sides receives equally, not enough so that other circuit operations, and loudspeaker is sounding not.When vehicle is crossed over lines, the light reflected signal that light receiving element 11,12 receives strengthens, the signal that receives amplifying circuit 2 outputs surpasses the threshold voltage of voltage identification 3, make voltage identification 3 output signals trigger monostable trigger 4, the output signal of monostable trigger 4 is open-minded with gating circuit 6, the output signal of gating circuit 6 makes loudspeaker 13 sounding by sound driving circuit 7, reminds driver's vehicle crossing over lines at this moment.If, then can be waken up with a start driver at this moment, in time revise travel direction and avoid traffic accident at once just in doze state.Loudspeaker can stop sounding automatically after 6 seconds under the effect of monostable trigger 4.The effect of modulator 5 is that the continuous sound is transformed to the interrupted sound, reminds effect to strengthen, and gating 0.8 second turn-offed 0.2 second.
This device circuit can be placed separately, also can be designed in the car load circuit of vehicle.This device is enabled and is turn-offed by switch independently.Photoemissive frequency is between 100Hz-100KHz.Photoemissive dutycycle is between 1%-99%.The dutycycle of prompt tone is between 10%-90%.
The selection of components and parts: transmitter unit: NE556, ballistic device: common high brightness LED, receiving element: TL084, receiving device: ordinary silicon photoelectric cell, voltage discriminating unit: LM311, monostable trigger element: CD4098, gating unit: MC14073, sound driver element: NE556,5:1 modulator: CD40106, power conversion: 7809,7805.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
