Abstract
The utility model discloses a radio two-way transceiver alarm for meeting vehicles for distance which is applied to the motor vehicle transportation of a highway of land. The radio two-way transceiver alarm is composed of a signal generator, a signal projector and a signal receiver. The radio two-way transceiver alarm is characterized in that when the signal projector emits the frequency signal from A direction of the motor vehicle, the signal receiver receives the frequency signal from B direction of a meeting motor vehicle; when the signal projector emits the frequency signal from B direction of the motor vehicle, the signal receiver receives the frequency signal from A direction of a meeting motor vehicle. The radio two-way transceiver alarm has the advantages that in a complicated terrain and climate, a motorist can obtain the information of the meeting motor vehicle which is out of sight in advance before a plurality of seconds, such as whether a meeting motor vehicle comes from the front, the meeting motor vehicle is a big motor vehicle or a small meeting motor vehicle. The radio two-way transceiver alarm is favorable for safely meeting or overtaking with leaving a distance. The interference caused by the noise from an acoustic horn for drivers and passengers is reduced.
Description
The utility model relates to the signal display device of a kind of land on-highway motor vehicle driving.
At present the signal display device at the automobile of the various models of land road running is a loudspeaker sound formula.This device before the narrow bend of the tor on daytime and intersected country or ramp in order to spy show the front possible send a car the time when misty rain weather (this particularly use), such problem is arranged: the one, have blindness, can not know early and accurately promptly whether the place ahead sends a car, thereby the meeting or overtake other vehicles of being not easy to give way.The 2nd, frequent use, loudspeaker noise (being in particular the loud horn noise) disturbs greatly chaufeur and passenger.
The purpose of this utility model is that a kind of highway of the radio bidirectional transmit-receive signal display device of sending a car will be provided, and it can help chaufeur to obtain the place ahead in advance outside sight line the information of sending a car and sending a car to cart or dolly.
The utility model is made up of signal generator, signal projector and signal receiver three parts.Signal generator could produce " all! All! " sound specific cart sound signal or "! ! " sound specific dolly sound signal, particular audio signal feed signals projector is launched.Signal projector need be launched A direction frequency signal or B direction frequency signal according to travel direction.Signal receiver receives the A direction frequency signal or the B direction frequency signal of sending a car and being launched.The signal receiver loudspeaker send " all! All! " when sound, sending a car is cart, loudspeaker send "! ! " when sound, sending a car is dolly.Signal projector and signal receiver be totally one frequency selective switch.When signal projector was launched the A direction frequency signal of this driving, signal receiver then received the B direction frequency signal of sending a car and being sent out; When signal projector was launched the B direction frequency signal of this driving, signal receiver then received the A direction frequency signal of sending a car and sending out.
The utility model divides 1 type and 2 types.1 type is specific " all for emission! All! " sound audio signals, use for cart; 2 types are specific " of emission! ! " sound audio signals, use for dolly.
The utility model is contained in by the automobile driver seat.Power supply connects automobile storage battery.Emitting antenna is 30 a centimeters long unbending metal filament, is contained on the headstock bumper/spoiler, and the outer front side of radiator is not in the hope of influencing the car body outward appearance and utilizing radiator to do shielding and make emitting antenna have certain orientation.Receiving wire then utilizes the radio aerial of its car.The utility model only is used for the daytime.
The utility model has the advantages that and to make chaufeur the several seconds obtains the place ahead the information of sending a car and sending a car to cart or dolly is arranged in advance outside sight line in the landform of complexity and weather, be beneficial to give way meeting or overtake other vehicles of safety, reduce of the interference of loudspeaker noise chaufeur and passenger.The utility model uses on the highway of Plain, and the take care effect of meeting of automatic prompting chaufeur is also arranged.The utility model must achieve the goal the side of installing and using on all automobiles, thereby favorable economic benefit can be arranged if implement.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing.
Fig. 1 is the circuit diagram according to the radio bidirectional transmit-receive formula highway meeting vehicle over watching alarm that the utility model proposes.
