Description

Night meeting prompting device

Technical Field

The utility model relates to a technical field of meeting at night, in particular to voice prompt device of meeting safety at night.

Background

With the improvement of the economic level of people and the rapid development of the automobile industry, automobiles have come into households, but the accompanying traffic accidents also rise year by year, wherein most of the accidents are caused by dazzling of vehicles or pedestrians driving in opposite directions due to the fact that drivers are used to use high-beam lights during driving at night. Therefore, many scientific researchers develop researches on meeting safety at night, and apply for many patents on meeting control and early warning.

The patent with application number 201710634231.1 proposes a safety control system for meeting vehicles at night; the patent with application number 201720237562.7 provides an automatic monitoring device for automobile high beam; the patent with application number 201810107792.0 provides an automatic control system and method for a high beam light during meeting; the patent with application number 201721093988.6 provides an automatic light changing device for meeting automobiles at night; the patent with application number 201721592934.4 proposes a vehicle meeting warning system, etc.

In the prior art including the above patents, first, only the high beam and low beam modes of the own vehicle are considered, that is, the high beam of the own vehicle is automatically switched to the low beam mode during the meeting process, and the high beam cannot be controlled or prompted to be turned off by the other party. Because some people like to turn on the high beam at night due to the visual effect of the people, even if the automobiles running oppositely meet with the twinkling car-meeting prompt, the opposite side still does not perceive the high beam and does not turn off the high beam, and therefore, the danger of dazzling caused by the light irradiation still exists.

Secondly, although some technologies provide a device for reminding a high beam of a vehicle meeting, or automatically switch the high beam of the opposite vehicle to a dipped beam by a control system during the meeting, whether the vehicle is driving the high beam is not considered, and the driver of the opposite vehicle is not actively reminded of converting the dipped beam of the opposite vehicle to the high beam after the meeting, if the light is dark, the driver of the opposite vehicle suddenly appears a visual blind area due to the fact that the headlamp is stimulated by the light of the opposite vehicle while the headlamp is turned dark, thereby causing great potential safety hazard.

Finally, some technologies have realized that two vehicles automatically change from high beam to low beam during a meeting and from low beam to high beam after the meeting. The technology judges whether the opposite side opens the high beam lamp or not by judging whether the ambient light brightness exceeds a set threshold value or not, and then automatically switches the high beam lamp and the low beam lamp. However, because the brightness of the far and near headlights of different types of vehicles is different, and a large part of vehicle owners privately install the vehicle lamps according to the visual effect of the vehicle owners, the phenomenon that the brightness of the near headlights exceeds the brightness of the common high beam exists, so that the technology of identifying whether to turn on the far and high beams or not by light intensity is limited, the technology of identifying whether to turn on the high beam or not by light intensity is large in error, the technology is not suitable for all vehicles, and meanwhile, the technology of identifying whether to turn on the high beam or not by the opposite vehicle or not by the brightness of the environment light also has large error under the condition that.

In addition, driving high beam lights in urban areas at night at present is already classified as a violation driving category and is subjected to punishment of warning and deduction. Therefore, the automatic switching between the high beam and the low beam of the vehicle cannot be realized by an automatic control system, and a driver needs to select the high beam and the low beam according to the actual environment.

Therefore, there is a need for a car-meeting device based on voice prompt, which can recognize a car-meeting signal emitted by a driver of the opposite party and twinkling the car light, and prompt the driver to turn off a high beam in time, so as to ensure the driving safety during the car-meeting.

The utility model discloses utilize the illumination intensity abrupt change value that light intensity sensor detected to judge the meeting car light scintillation signal of other side's car light, and then trigger the voice prompt system of vehicle, make voice prompt system send "please close the warning sound of far-reaching headlamp", then the manual headlight that closes, make the other side's vehicle not receive the influence that self vehicle headlight shines, reduce the traffic violation simultaneously. The device has the characteristics of simple structure, accurate judgment, convenience in installation, economy, practicability and the like.

Disclosure of Invention

The utility model aims to solve the technical problem that a night meeting suggestion device convenient to arrange, simple structure and can be real-time, react to the warning signal of meeting vehicle fast is provided to above-mentioned prior art.

The utility model discloses a realize like this: a night meeting reminder device comprising: illumination sensor, singlechip and voice broadcast system. The illumination sensor is connected with the single chip microcomputer, and the single chip microcomputer is connected with the voice broadcasting system.

The illumination sensor is used for receiving headlamp light of an opposite running vehicle and converting an illumination intensity value into a voltage value.

The single chip microcomputer is a control center of the system and is used for receiving the illumination intensity voltage value detected by the illumination sensor, judging the voltage value and triggering the voice broadcasting system when detecting that the voltage value changes suddenly within 1 second. Meanwhile, the singlechip has a voice preset function and can download any recorded voice through the USB interface.

The voice broadcasting system comprises a singlechip voice triggering module and an external loudspeaker and is used for receiving the instruction of the singlechip and broadcasting the preset voice of 'please turn off the high beam' through the loudspeaker.

Compared with the prior art, the utility model relates to a meeting suggestion device at night has simple structure, simple to operate, and advantages such as reaction rapidly can make the vehicle of meeting at night react to the meeting signal rapidly to in time close the headlight, avoid because of the dazzling problem that opposite headlight shines and arouses, the emergence of the traffic accident that has significantly reduced.
