Description

In a kind of vehicle going at night, automatically identify the device of roadblock

Technical field

The utility model belongs to traffic safety field, specifically relates to the device of automatically identifying roadblock in a kind of vehicle going at night.

Background technology

Along with the development of national economy, country road and city highway are also in develop rapidly.But because the category of roads of these highways is lower, and be all close to resident, make to have some road obstacles that affect traffic on highway and occur.When automobile is during at night running, because the speed of a motor vehicle is fast, or driver fatigue, very likely make driver and the collision of front barrier, thereby cause driving dangerous.

At present, also do not have low, the easy to operate device of a set of cost to carry out driver assistance identifies front and whether has road obstacle in the time of night running.

Utility model content

Automatically the device of identification roadblock is provided to provide in a kind of vehicle going at night the purpose of this utility model, adopt this device better driver assistance in night running, identify front roadblock and reminded, thereby the safety of guarantee driver drives vehicle; And this installation cost is low, easy to operate.

For achieving the above object, the utility model is achieved by the following technical solutions.

In a kind of vehicle going at night, automatically identify the device of roadblock, it is characterized in that, comprise single-chip microcomputer, alarm, roadblock level identification device, the I/O input end electrical connection roadblock level identification device of described single-chip microcomputer, the I/O output terminal electrical connection alarm of described single-chip microcomputer; Described roadblock level identification device comprises infrared ray sensor, image dissector, the input end of the output terminal electrical connection image dissector of described infrared ray sensor, and the output terminal of described image dissector is electrically connected the I/O input end of described single-chip microcomputer.

Feature of the present utility model and further improvement are:

The power end electrical connection power supply of described single-chip microcomputer, is electrically connected with switch between the power end of described single-chip microcomputer and power supply.

Described single-chip microcomputer is 8051 single-chip microcomputers.

Described roadblock level identification device is arranged on car body dead ahead, and its height is consistent with the bottom surface height on chassis.

Described alarm is LED traffic lights light crossing-signals, is arranged on pilothouse inside.

Described power supply is arranged on pilothouse inside.

Whether this device just can accurately identify roadblock height higher than automobile chassis by infrared ray sensor before automobile approaches roadblock, and then by single-chip microcomputer, information was passed to alarm, thereby can make driver's pre-decelerating, ensured traffic safety.And this principle of device is simple, convenient operation, cost is low, is convenient to universal and popularization on a large scale.

Brief description of the drawings

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

Fig. 1 is the circuit connection diagram of automatically identifying the device of roadblock in a kind of vehicle going at night of the present utility model.

Embodiment

With reference to Fig. 1, in a kind of vehicle going at night of the present utility model, automatically identify the circuit connection diagram of the device of roadblock.This device comprises single-chip microcomputer, power supply, switch, alarm, roadblock level identification device; Roadblock level identification device comprises infrared ray sensor, image dissector; What single-chip microcomputer adopted is 8051 single-chip microcomputers, and alarm is LED traffic lights light crossing-signals; Power supply is electrically connected with the power end of single-chip microcomputer by switch, the input end of the output terminal electrical connection image dissector of infrared ray sensor, the I/O input end of the output terminal electrical connection single-chip microcomputer of image dissector, the I/O output terminal electrical connection alarm of single-chip microcomputer; Power supply, alarm are arranged on respectively pilothouse inside, and roadblock level identification device is arranged on car body dead ahead, and its height is consistent with the bottom surface height on chassis.

The principle of work of this device is as follows: this automobile that prestores in single-chip microcomputer allow current maximum height; Driver, in the time of night running, opens switch, infrared ray sensor real-time collecting road ahead obstacle situation, and give image dissector communication, and analyze the height of front roadblock by image dissector, be sent to single-chip microcomputer; Single-chip microcomputer compares the elevation information of image dissector transmission and the elevation information prestoring, when transmit height higher than prestore height time, LED traffic lights light crossing-signal in pilothouse is shown in red, driver can hide in time this barrier or stop in time travelling and avoid the generation of accident, when transmit height lower than prestore height time, LED traffic lights light crossing-signal is green, and driver, without doing any processing, continues to travel.In the time not needing to detect, can closing switch, stop the operation of this device.

Whether this device just can accurately identify roadblock height higher than automobile chassis by infrared ray sensor before automobile approaches roadblock, and then by single-chip microcomputer, information was passed to alarm, thereby can make driver's pre-decelerating, ensured traffic safety.And this principle of device is simple, convenient operation, and cost is very low, is convenient to universal and popularization on a large scale.

Although below by reference to the accompanying drawings embodiment of the present utility model is described, but the utility model is not limited to above-mentioned specific embodiments and applications field, above-mentioned specific embodiments is only schematic, guiding, instead of restrictive.Those of ordinary skill in the art, under the enlightenment of instructions, in the case of not departing from the scope that the utility model claim protects, can also make a variety of forms, and these all belong to the row of the utility model protection.
