Description
Technical field
The invention belongs to traffic safety technology fields, and in particular to a kind of night freeway tunnel hole alarming device.
Background technique
With the development of China's economic society, China's highway total kilometrage and car steering number rise year by year.Therewith
And come, it is that traffic accidents take place frequently, especially mountainous area highway.Highway Dangerous Area basic bit Yushan Hill
Area, often bridge tunnel is than high in these sections, and tunnel due to " light adaptation ", " dark adaptation ", more easily leads to friendship compared with bridge
The generation of interpreter's event.And the Emergency Vehicle Lane outside due to tunnel has often been arrived at tunnel portal and can have been changed, for example, suddenly in
It is disconnected or narrow, therefore, freeway tunnel hole be arranged it is a kind of can be at night or bad light when to driver to warn
Device, it appears it is more significant.
Summary of the invention
The purpose of the present invention is to provide a kind of night freeway tunnel hole alarming devices, can be at night to emergency
Driver on lane is to warn.
To achieve the goals above, technical scheme is as follows: a kind of night freeway tunnel hole warning dress
It sets, it is characterised in that the alarming device includes
Be delayed pressure-sensitive switch, the delay pressure-sensitive switch be placed in the Emergency Vehicle Lane surface layer in front of tunnel portal it
Under, whether there is vehicle that will enter tunnel portal for detecting on Emergency Vehicle Lane, the delay pressure-sensitive switch is normally opened opens
It closes, when having detected vehicle, the delay pressure-sensitive switch closure, and when vehicle sails out of delay pressure-sensitive switch induction
Switch time delay is closed behind region；
Photoconductive switch, the photoconductive switch are placed on the sign board in front of tunnel portal, for detecting extraneous intensity of illumination, institute
Stating photoconductive switch is normal open switch, when intensity of illumination is lower than setting value, photoconductive switch closure；
Warning lamp, the warning lamp are placed in tunnel portal, connect after connecting with pressure-sensitive switch equipment, photoconductive switch with power supply
It connects, is warned for the vehicle to traveling in Emergency Vehicle Lane.
Further, pressure-sensitive switch is greater than 100m at a distance from tunnel portal.
Further, warning lamp uses high-brightness LED strobe warning lamp, and the lamp visibility is high, and service free in use makes
Used time can continuous quick three stroboscopic flash of light form, generate strong visual impact, warning effect is preferable.
Further, the pressure-sensitive switch is using EYX15-6 delay pressure switch.
Further, photoconductive switch uses PCSS type photoconductive switch.
At night, photoconductive switch is in closed state, near tunnel portal, as driver because bad visibility reason is driven into
When Emergency Vehicle Lane, triggering pressure-sensitive switch closure constitutes closed circuit, so that being placed in the warning lamp flashing of tunnel portal, rises
To the purpose of warning driver.The present invention has a low cost, simple and compact for structure, reasonable and small in size, light-weight, use operation
Easy advantage.
Detailed description of the invention
Fig. 1 is the circuit diagram of invention；
Fig. 2 is the work flow diagram of invention；
Fig. 3 is the instrument installation site figure of invention.
It include: warning lamp 1, delay pressure-sensitive switch 2, photoconductive switch 3, tunnel portal 4, Emergency Vehicle Lane 5, mark in figure
Board 6.
Specific embodiment
A kind of night freeway tunnel hole alarming device, it is characterised in that the alarming device includes
Be delayed pressure-sensitive switch 2, the delay pressure-sensitive switch be placed in the Emergency Vehicle Lane surface layer in front of tunnel portal it
Under, for detecting whether there is vehicle that will enter tunnel portal, the delay pressure-sensitive switch be normal open switch, when detecting
When having vehicle, the delay pressure-sensitive switch closure, and can prolong after vehicle sails out of delay pressure-sensitive switch induction region
Long switch-closed time (extend time be generally 1 ~ 5s) takes 3s in the present embodiment delay time, and the delay pressure sensitive is opened
It closes using EYX15-6 delay pressure switch；
Photoconductive switch 3, the photoconductive switch are placed on the sign board in front of tunnel portal, for detecting extraneous intensity of illumination,
The photoconductive switch is normal open switch, when intensity of illumination is lower than setting value, photoconductive switch closure；
Warning lamp 1, the warning lamp are placed in tunnel portal position corresponding with Emergency Vehicle Lane, with pressure-sensitive switch equipment,
It is connected to power supply after photoconductive switch series connection, for being warned to the vehicle that will enter tunnel portal.
Photoconductive switch 3 uses PCSS type photoconductive switch, and the photoconductive switch is by photo resistance (GaAs), resistor (resistance
Be worth about 7.5M Ω), diode, thyristor groups at.Its principle is, in the case where there is illumination, due to the resistivity of photo resistance
Very low, alternating voltage divides between resistor and photo resistance in the unidirectional pulse DC voltage after diode rectification
Voltage afterwards is small, causes the voltage for being added in thyristor control electrode small, thyristor can not be connected at this time, and structure does not become and is closed back
Road；In the case where no illumination, since the resistivity of photo resistance is very high, alternating voltage is in the list after diode rectification
Voltage after dividing between resistor and from photo resistance to pulse feature DC voltage is big, leads to the electricity for being added in thyristor control electrode
Pressure is big, and thyristor can be connected at this time, to constitute closed circuit.
Warning lamp 1 uses high-brightness LED strobe warning lamp, and lamp visibility is high, service free in use, and when use can connect
The flash of light form for continuing quick three stroboscopic, generates strong visual impact, and warning effect is preferable.
When night or bad light, photoconductive switch is in closed state, near tunnel portal, as driver because of sight
When poor prognostic cause drives into Emergency Vehicle Lane, triggering pressure-sensitive switch closure constitutes closed circuit, so that being placed in the police of tunnel portal
Show that lamp flashes, plays the purpose of warning driver.
The present invention has low cost, simple and compact for structure, reasonable and small in size, light-weight, easy to use, work people
Member is without the advantages of carrying out special training.
With reference to Fig. 1, Fig. 2 and Fig. 3, when work, delay pressure-sensitive switch 2 is placed in certain distance in front of tunnel portal
Under the Emergency Vehicle Lane surface layer at place's (considering driver reaction time and braking action time, it is proposed that distance is greater than 100m), by light
It leads switch 3 to be placed on highway signboard, warning lamp 1 is placed on tunnel portal.
When night or light bad (such as hazing), photoconductive switch 3 is closed, when there is vehicle that the reasons such as bad visibility is answered to sail out of just
Normal route, after driving into Emergency Vehicle Lane, Time delay pressure-sensitive switch 2 is closed, and constitutes closed circuit at this time, and warning lamp 1 lights,
Driver is reminded to take the evacuation behaviors such as braking.It, can be along tunnel portal outline in order to preferably show tunnel portal position
Warning lamp is set, prevents driver because bad visibility does not see tunnel portal and accident occurs in evacuation.
