Description

The travelling in fog day pilot lamp

The utility model relates to the pilot lamp in a kind of highway communication, particularly the travelling in fog day pilot lamp.

When vehicle travelled in the greasy weather, can only rely on the antifog light of automobile to throw light on, because greasy weather light is very dark, visibility is very low, has only 20～50 meters.Usually require automobile that 100～150 meters spacing is arranged, but when travelling in the greasy weather, the driver can't grasp the garage distance, on expressway or highway, because car speed is higher, the end to end collision traffic hazard of a succession of automobile takes place easily, thereby, usually close a part of highway during the greasy weather, cause the highway operation efficiency to reduce, gain on investments is not good.

The purpose of this utility model provides a kind of travelling in fog day pilot lamp, thereby shows whether the place ahead has car to pass through, so that the driver controls the speed of a motor vehicle, and the difficult problem that the solution highway greasy weather can not drive a vehicle.

The purpose of this utility model realizes with following technical proposals: a kind of travelling in fog day pilot lamp, comprise housing, be provided with two pilot lamp of red light and green light in the housing, red light and the green light one group of normal off normally closed relay that is connected in parallel, relay coil connects control circuit, control circuit comprises that sensor, amplifier, shaping circuit, comparison trigger connect successively, and relatively the trigger output terminal connects delay circuit and executive circuit.

Described sensor adopts acoustic control sensor, vibration transducer, light control sensor, vibration, acoustic control or door sensor, one of mist control sensor and above-mentioned four kinds of sensors composition and door sensor.

The utility model utilization vibration, acoustic control, light-operatedly be connected control circuit with mist control sensor, when automobile passes through, sensor is connected control circuit, circuit breaker energising and time-delay, and red light is bright, can indicate the place ahead to have automobile to pass through soon, remind the driver to control the speed of a motor vehicle, after the time-delay, red light goes out, indication front vehicles operating range is far away, and the rear driver can cruising.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
