Abstract
The utility model discloses an infrared overtaking buzzer which is an infrared overtaking signal transmitting and receiving device used in a vehicle cab in road traffic. The present overtaking buzzer is a whistling making noise, whose signal is not easily received by the other party due to weather, etc. The infrared overtaking buzzer adopts the infrared remotely controlled principle; the cab of each vehicle installs an infrared overtaking buzzer provided with an infrared transmitting circuit, an infrared receiving circuit, and a circuit using a loudspeaker to change into an audible signal. The infrared overtaking buzzer replaces the whistling overtaking buzzer, which highly improves the directivity, reduces noise on the highway, and improves overtaking safety.
Description
A kind of infrared signal of highway communication car operator platform that is applicable to transmits and receives device.
The utility model is a kind of improvement that belongs to the signal of overtaking other vehicles at present.The existing signal of overtaking other vehicles is to send by toot flute.But as the signal of overtaking other vehicles a lot of defectives are arranged with blowing a whistle.As blowing a whistle with loud horn, noise is very big, and is influential to environment, also harmful to human body; As blowing a whistle with woofer, the other side is difficult for hearing; Especially under inclement weather, the other side's operator's compartment window closes, and owing to other noises, does not often hear the signal of overtaking other vehicles of back.Therefore, the serious accident that causes because of overtaking other vehicles is occupied cooresponding ratio in traffic accident.
The utility model changes existing loudspeaker whistle signal at this present situation, has solved this problem.
The utility model has adopted infrared signal to replace existing whistle signal.Utilize the infrared control principle of shaking, on the operator platform of each commuter vehicle, adorn an infrared news Chinese percussion instrument of forming by infrared emission circuit and infrared receiving circuit and loudspeaker of overtaking other vehicles.The infrared news Chinese percussion instrument of overtaking other vehicles has infrared receiving unit of an infrared emission partial sum.The infrared emission part is launched the infrared ray that the infraluminescence diode sends forward with multi-resonant oscillating circuit; Infrared acceptance is partly used up quick pipe and is received infrared signal and by amplifying circuit it is amplified then, and transfers it to audible signal with loud speaker.
In the infrared part, the infrared emission head of being made up of infrarede emitting diode is contained in the front car light lampshade of commuter vehicle to increase directivity, in infrared receiving unit, photosensitive tube and amplifying circuit are partly formed in the back car light lampshade that infrared receiving terminal is contained in commuter vehicle, to increase receiving sensitivity, before photosensitive tube, be covered with the red plastic lens, to increase anti-interference resistance.Infrared emission head, infrared receiving terminal and power supply insert five core jacks with five core plugs, and corresponding with it respectively circuit joins.
The utility model compared with prior art with the infrared ray signal signal of overtaking other vehicles that replaces blowing a whistle of overtaking other vehicles, has been eliminated the noise that causes by blowing a whistle, and has avoided not hearing in rough weather the dangerous situation of the signal of overtaking other vehicles, and has increased the safety of overtaking other vehicles.
Accompanying drawing is an embodiment of the present utility model.
Fig. 1 is the constructional drawing of the infrared news Chinese percussion instrument of overtaking other vehicles.
Fig. 2 is for receiving, amplify infrared signal and transfer it scheme circuit of audible signal in the infrared news Chinese percussion instrument of overtaking other vehicles.
Fig. 3 is the scheme circuit of infrared overtake other vehicles news Chinese percussion instrument infraluminescence pipe and multi-resonant oscillating circuit.
Among Fig. 1, in five core jacks (4) on five core plugs (3) the insertion plastic casings (8), power light (5) is bright.Connect infrared emission button (6), emission indicator lamp (7) is bright, and the infrared ray that will be contained in infrared emission head (2) emission in the front truck lampshade by the multi-resonant oscillating circuit on the wiring road version (9) is forwards launched.The emissive power of infrared emission head is greater than 200 milliwatts, and the modulating frequency of multi-resonant oscillating circuit is in 30 to 60 weeks.Be contained in the infrared receiving terminal (1) of back in the lamp shade by what photosensitive tube and amplifying circuit were formed, the infrared signal that receives amplified, by being converted to the audible signal driver by change-over circuit on the wiring road version (9) and loud speaker (10).Add the red plastic lens before the photosensitive tube, infrared receiving terminal (1) can receive 20 meters infrared rays with interior infrared emission head (2) emission.
Among Fig. 2, D is a photosensitive tube, and the dotted line front is corresponding to infrared receiving terminal (1), and it is on circuit is contained in by wiring road version (9).
Among Fig. 3, D is a luminotron, corresponding to the power light among Fig. 1 (5).DH is an infrared light-emitting diode, corresponding to infrared emission head (2).
Claims (4)
1, a kind of infrared signal overtaking device that is used for highway communication car operator platform.Feature of the present utility model infrared emission part that to be this device be made up of an infraluminescence pipe and multi-resonant oscillating circuit and the circuit that receives, amplifies infrared signal also transfer received signal to infrared receiving unit and plastic casing (8) formation that the audible signal circuit is formed by loud speaker (10).
2, infrared signal overtaking device according to claim 1, the infrared emission head that feature of the present utility model is made up of the infraluminescence pipe (2) is contained in the front car light of commuter vehicle; The infrared receiving terminal of being made up of photosensitive tube and reception amplifying circuit (1) is contained in the back car light of commuter vehicle.
3, according to claim 1 and the described infrared signal overtaking device of claim 2, feature of the present utility model is in its infrared receiving terminal (1), and there are red plastic lens the photosensitive tube front.
