Abstract
The utility model relates to a signal device, in particular to an acousto-optic warning device for vehicle safety meeting on sudden turn road, which is composed of an acoustic pick-up / telephone transmitter, an acoustic control circuit and an acousto-optic circuit. The output end of the acoustic pick-up / telephone transmitter is connected with the input end of the acoustic control circuit, and the output end of the acoustic control circuit is connected with the acousto-optic warning circuit through a connecting lead. When the utility model is used, the acoustic pick-up / telephone transmitter is positioned on the point far way from the front of sudden turn road of a high road about 50 m, and a badge of entering secure line is set, so that the acousto-optic warning circuit can be equipped on a proper position at the other side of the sudden turn road of the high road according to the highway condition. When a vehicle enters the secure line or / and sees the badge, the driver pushes the horn, so at the same time the acousto-optic warning circuit dispatches warning acousto-optic signals to prompt the driver to reduce the speed and keep the principle of comity before entering the sudden turn road. The utility model is especially suitable to the crossing with a plurality of bends (for example lacet roads, etc.) or the unwatched crossing in countryside and hilly region.
Description
Technical field
The utility model relates to a kind of telltale, the acousto-optic warning device during in particular for the sharp highway turn automobile meeting.
Background technology
Racing crook on the highway is the multiple ground of road traffic accident, a large amount of low-grade highways in especially vast rural area, mountain area, because of bend more anxious, be obstructed in driver's the visual field, multiple factors such as the road surface is narrow in addition, vehicle is many, the speed of a motor vehicle is too fast, often generation can't be dodged or be had little time to brake and cause the traffic hazard of car crash.Existing way is at the place, sharp turn convex mirror to be set, but often suffers damage.Notification number provides a kind of railway and highway intersection security alerting system for the patented claim of CN2031779U, be made up of emitter that is installed in the place, level crossing and the receiving trap that is installed on the motor vehicle, emitter comprises alerting signal coding, interface, high-frequency emission and power unit; Receiving trap comprises high frequency reception, interface, alerting signal decoding, sound and light alarm time-delay control Driver Circuit and power unit.When train vibration influence is launched alerting signal by emitter to apart from the level crossing certain distance time, when motor-driven vehicle going receiving trap on the motor vehicle to apart from the level crossing certain distance time is received alerting signal reliably, and carry out sound and light alarm and show.Notification number provides a kind of Rail Highway crossing on the same level crossing automatic alarming to establish the hurdle device for the patent of CN2152730Y, is made up of control box, acousto-optic show case, automatic control circuit and guardrail actuating mechanism circuit.Notification number is made up of loudspeaker, sound control circuit, relay, electronic timer and signal lamp power supply for the safety feature that the patent of CN203878U provides a kind of railway and highway intersection to use.
Summary of the invention
The utility model aims to provide a kind of acousto-optic warning device when being used for the sharp highway turn automobile meeting.The utility model has adopted following technical scheme for this reason, sails to highway visual field blind spot zig zag at vehicle, travels next vehicle with the acousto-optic warning signal in time for the zig zag opposite side, reminds the driver to enter zig zag front reduction gear, comity.
According to technique scheme, the utility model is provided with acoustic pickup/microphone, sound control circuit, acousto-optic warning circuit, the input end of the output termination sound control circuit of acoustic pickup/microphone, and the output terminal of sound control circuit connects acousto-optic warning circuit through connecting lead.
Sound control circuit can be made up of speech IC, amplifying circuit, delay circuit and electronic switching circuit, the output terminal of the input termination acoustic pickup/microphone of speech IC, input amplifier connects the output terminal of speech IC, the output terminal of the input termination amplifying circuit of delay circuit, the input termination delay circuit output terminal of electronic switching circuit, the switch of electronic switching circuit connects acousto-optic warning circuit.Acousto-optic warning circuit can be established siren and lighting display circuit, and lighting display circuit can adopt the high brightness LED display circuit.
During use, acoustic pickup/microphone is arranged on about 50m place, sharp highway turn the place ahead, and establish marks such as entering safety line, acousto-optic warning circuit can be located at sharp highway turn opposite side appropriate location according to road conditions, vehicle enters safety line or/and when seeing mark, driver's loudspeaker that ring, acousto-optic warning circuit sends the caution sound and light signal simultaneously, reminds the driver entering racing crook front reduction gear, comity.The utility model is specially adapted to many bends such as rural area, mountain area (for example sky way etc.) or railway cross without watch.
