Abstract
The utility model discloses an infrared warning device for preventing vehicles from bumping walls on curved tunnel road sections. The device comprises a single chip microcomputer, at least one alarm and at least one infrared distance measurement sensor arranged in a tunnel, wherein each alarm and each infrared distance measurement sensor are connected with the single chip microcomputer respectively. The infrared warning device is mainly used for horizontal curved road sections of the tunnel and visual light and shade transition sections at exits and entrances, monitors the transverse space between the vehicles and the side walls of the tunnel in real time by means of the infrared distance measurement sensors, warns the conditions that the transverse space is less than safe distance, and improves the traveling safety on the curved tunnel and the transition sections at the exits and entrances.
Description
Technical field
The utility model belongs to the electronic auto-control technology field, is specifically related to a kind of curved tunnel highway section based on infrared sensor and prevents that vehicle from hitting the infrared warning device of wall.
Background technology
The driver is by getting into outside the well-lighted tunnel in the dim tunnel when driving through the tunnel by day; Though generally can be provided with light in the tunnel; Because consider economic problems, its brightness also can only maintain on the lower level, the inside and outside luminance difference in hole is extremely greatly different.Therefore, be driver's eyesight limber up period the former seconds (under the speed per hour 60km/h situation, the about 50m of running distance) after getting into the tunnel, promptly there be so-called " black-hole effect ", when this section debug time and distance are caused danger just the most easily.And pass through than long tunnel when exporting when vehicle, the outside brightness in tunnel is high, and outlet looks it is " white hole ", and this moment, the driver can descend because of the dazzle effect cause visual capacity, promptly produced " white hole effect "; At night, owing in the tunnel illumination is arranged, tunnel internal is bright, the outside is dark, and the place, gateway can produce " black-hole effect " and " white hole effect " equally.The gateway, tunnel is the highway section occurred frequently of traffic hazard.Show that according to statistics place, gateway, tunnel accident rate is about 3 times of other highway sections, its main cause is exactly that the driver's of place, gateway, tunnel vision exists the sudden change problem.
According to " specification of the highway route design ", the design of the horizontal alignment in tunnel is the same with the open-wire line road, can adopt straight line and curve.When adopting curve design,, section certainly will to be widened for guaranteeing sighting distance because tunnel side wall must be upright; So inner curve place, tunnel section variation is bigger, it is inaccurate to cause the driver that horizontal spacing is judged, is prone to take place Vehicular impact tunnel wall phenomenon.In addition, driver's the fatigue driving tunnel wall phenomenon that also can bump, the prior-warning device that does not also have this phenomenon of prevention to take place in the prior art.
Summary of the invention
To the defective or the deficiency of prior art, the purpose of the utility model is to provide a kind of curved tunnel highway section vehicle to hit the wall infrared warning device.
For realizing above-mentioned technical assignment, the utility model is taked following technical solution:
A kind of curved tunnel highway section prevents that vehicle from hitting the infrared warning device of wall; It is characterized in that; This device comprises that single-chip microcomputer, at least one alarm and at least one are installed on the infrared distance sensor in the tunnel, and each alarm is connected with single-chip microcomputer respectively with each infrared distance sensor.
Said single-chip microcomputer adopts the MSP430 single-chip microcomputer.
Said device comprises two infrared distance sensors that are installed on tunnel one side walls, and the horizontal mounting distance between these two infrared distance sensors is 2 meters.
The device of the utility model is mainly used in the tunnel Horizontal Curve Sections and imports and exports vision light and shade transition section; Device utilizes the horizontal spacing of real-time monitor vehicle of infrared distance sensor and tunnel-side; To less than safe distance situation carry out early warning, lifting curve tunnel and import and export the travel safety of transition section.
Compared with prior art, the beneficial effect of the utility model is following:
(1) device adopts the infrared ray image data, and measuring accuracy is high, and is convenient flexibly;
(2) this installation cost is cheap, be convenient to promote, and the device used unit is easy to buy, and low price makes things convenient for large-scale promotion to use.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Below in conjunction with embodiment and accompanying drawing the utility model is done further explain.
Embodiment
With reference to figure 1; The curved tunnel highway section of the utility model prevents that infrared warning device that vehicle hits wall from comprising that single-chip microcomputer, at least one alarm and at least one are installed on the infrared distance sensor in the tunnel, and each alarm is connected with single-chip microcomputer respectively with each infrared distance sensor.Single-chip microcomputer wherein adopts the MSP430 single-chip microcomputer.
A concrete example, device comprise two infrared distance sensors that are installed on the wall of the same side, tunnel, and the horizontal mounting distance between these two infrared distance sensors is 2 meters.The length of vehicle generally surpasses 2m, when a vehicle sails the monitored area into, can block the signal of two adjacent infrared distance sensors simultaneously; Single-chip microcomputer is analyzed these two signals; In two signals,, will send alerting signal as long as a signal that signal monitored is arranged less than the safe distance of setting; Two sensors are worked simultaneously and can be avoided wrong report, improve the traffic safety in tunnel.
Embodiment:
The curved tunnel highway section of this embodiment prevent infrared warning device that vehicle hits wall comprise the horizontal spacing that is installed on the tunnel-side be 2m, apart from 12 infrared distance sensors of floor level 1m; In the tunnel near the inlet relative both sides wall on respectively by six infrared distance sensors are arranged, each infrared distance sensor is installed by rivet; Set up an alarm between per two infrared distance sensors, totally six alarms, each infrared distance sensor is connected with single-chip microcomputer respectively with each alarm.
Open anti-collision prewarning apparatus; When vehicle gets into the monitored area; Single-chip microcomputer is started working, and infrared distance sensor is passed to single-chip microcomputer analysis with the distance signal that collects, when vehicle apart from the signal feedback of tunnel wall distance during smaller or equal to 0.75m; Then the Single-chip Controlling alarm is sounded and is reported to the police and continued for 2 seconds, when the vehicle that monitors apart from the signal feedback distance of tunnel wall all clear during greater than 0.75m.
Used electronic devices and components are commercially available known product in the device of the utility model, and those skilled in the art can realize the connection of each electronic devices and components according to the application's technique effect.
