More, which is also tending to be mature.But it is directed to traffic field of the night without the such Frequent Accidents in traffic lights intersection
The few effective early warning systems of scape.The intersection of this no traffic lights is in cities and towns rural area and expressway entrance and exit
It is generally existing, even if there is the go slowly prompting of Indicating lamp board of traffic to be easy in this way since the subjective judgement of driver can also be neglected
Cause traffic accident.
Utility model content
To solve the problems, such as that night easily causes traffic accident because sight is inadequate without traffic lights intersection, this reality
A kind of night is provided without traffic lights intersection vehicle automatic early-warning system with novel, it can be on the road of no traffic lights
Mouthful to will by vehicle and other crossings vehicles or pedestrians information, with vehicle-mounted voice casting form remind driver,
To reduce traffic accident.
To achieve the above object, the utility model adopts the following technical solutions:
A kind of night, it included the road conditions detection dress at crossing without traffic lights intersection vehicle automatic early-warning system
It sets, the visible photoreceiver of the VISIBLE LIGHT EMISSION machine in roadside and front of the car, road conditions detection device real-time detection intersection is left
The information of right both direction vehicle and pedestrian is sent to row using the LED street lamp in the roadside by the VISIBLE LIGHT EMISSION machine in roadside
Sail to the vehicle at corresponding crossing, the visible photoreceiver of the front of the car receives after signal by way of vehicle-mounted voice is broadcasted
The information of the crossing or so both direction vehicle and pedestrian is passed into driver.
Further, road conditions detection device includes that the detection device being sequentially connected, data processing equipment and data are wirelessly sent out
Injection device, detection device are acquired the corresponding traffic information in each intersection, and collected information is sent to data
Processing unit is handled, and treated information by data wireless launcher is sent to corresponding VISIBLE LIGHT EMISSION
Machine.
Further, it is seen that optical sender includes the data wireless reception device being sequentially connected, data conversion device and can
Light-exposed emitter, data wireless reception device are received the traffic information from data wireless launcher accordingly,
The information received is converted into visible light signal by data conversion device, and the visible light signal is passed through into VISIBLE LIGHT EMISSION
Device is sent to the vehicle for driving to corresponding crossing.
Further, it is seen that photoreceiver includes visible optical receiver apparatus, chromacoder and the voice being sequentially connected
Casting, it is seen that optical receiver apparatus receives the optical signal that VISIBLE LIGHT EMISSION device issues, which is passed through chromacoder
It is converted into voice messaging, and traffic information is passed to driver by the vehicle audio being connected in the form of voice broadcast.
The utility model has the advantages that
1. the utility model utilizes the advantages of visible light communication, the visual field can be provided to vehicle at night, also can be realized
Communication between road car, so that intersection two sides blind area situation is timely and effectively passed to driver, so as to driver
Correct driver behavior is made, guarantees driving safety, reduction night causes without traffic lights intersection because sight is inadequate
Traffic accident.
2. the utility model is the crossing vehicle driving phase due to the direction for the LED street lamp illumination that each intersection is installed
Pair direction, thus the vehicle at other crossing would not receive the crossing VISIBLE LIGHT EMISSION machine issue signal, to keep away
The interference between signal is exempted from；The utility model utilizes the characteristics of good directionality of visible light communication simultaneously, so that practical communication
Cost and practicability are better than other communications.
