Abstract
The invention discloses an automatic frequency modulation radio anti-fog traffic light, which comprises red, yellow and green lights, a radio transmitter, a receiving frequency notification apparatus, and a vehicle-mounted receiving device. The traffic light not only emits light signals, but also emits radio traffic signals; the receiving frequency notification apparatus continually notifies automobiles passing through the intersection of transmitting frequency of the traffic signals; and the vehicle-mounted receiving device automatically adjusts the receiving frequency so as to receive and display the radio traffic signals, and is not disturbed by other traffic lights. Under the weather conditions of fog, sand storm, rain and snow, the automobiles can still clearly receive the traffic signals.
Description
Technical field
The present invention relates to a kind of stop-light that can send radio wave signal, particularly a kind of automobile of notifying is regulated the stop-light that receive frequency receives radio wave signal automatically.
Background technology
Existing stop-light can be indicated traffic well at normal weather; But, in the greasy weather, sandstorm, under the weather conditions of low visibility such as sleet sky, automobilist even do not see several meters outer stop-lights, the crossroad of driving this moment is a very dangerous thing.
Summary of the invention
The objective of the invention is to provide a kind of can be in the greasy weather, sandstorm, the stop-light of vehicle pass-through is effectively indicated in the sleet sky.
For realizing purpose of the present invention, a kind of stop-light provided by the invention comprises red, yellow, green traffic, transmitting set, receive frequency notifying device, vehicle-mounted receiver apparatus.Stop-light passes through transmitting set, launch wireless traffic indicator signal with the particular transmit frequency of this group traffic lights, automobile is during near stop-light, the receive frequency notifying device in roadside goes to tell the transmission frequency of automobile front stop-light with a unified frequency of notification emission wireless notification signal, it is consistent with transmission frequency that vehicle-mounted receiver apparatus is regulated receive frequency automatically, thereby receive wireless traffic indicator signal, show by light or voice.When automobile is positioned at different crossings, just can remove to receive the signal of that group stop-light of automobile front like this, not disturbed by the wireless signal of other stop-lights with different receive frequencies.Transmitting set, the radio wave coverage of receive frequency notifying device all in suitable scope, make the automobile at this crossing can receive signal, do not disturb the automobile at other crossings again.Vehicle-mounted receiver apparatus always with at present received peak signal as notification signal, avoided the interference of wireless signal of the receive frequency notifying device at other crossings.
Because transmitting set sends wireless traffic indicator signal, can not be subjected to the restriction of any weather conditions and effectively indicate traffic.Because the vehicle-mounted receiver apparatus of receive frequency notifying device notice automobile changes receive frequency automatically, the wireless traffic indicator signal that the stop-light that makes automobile can both correctly receive the front at any crossing sends is not subjected to the interference of other traffic lights.Simultaneously, adopt technical scheme of the present invention, make structure of the present invention simple and reliable relatively and easy to implement.
Description of drawings
Purpose of the present invention, feature and advantage thereof will be in conjunction with the embodiments, are further described with reference to accompanying drawing.
Fig. 1 is the schematic diagram of one group of wireless antifog stop-light of the present invention.
Fig. 2 is the schematic plan view of four groups of wireless antifog stop-lights.
1. red leds among the figure, 2. yellow indicator lamp, 3. green indicating lamp, 4. transmitting set, 5. wireless traffic indication electric wave, 6. receive frequency notifying device 7. wireless notification signal, 8. vehicle-mounted receiver apparatus.
Embodiment
In Fig. 1, red led (1), yellow indicator lamp (2) and green indicating lamp (3) pass to transmitting set (4) to the traffic indicator signal, transmitting set is launched with specific transmission frequency the traffic indicator signal by wireless traffic indication electric wave (5), automobile is by the crossroad time, the receive frequency notifying device (6) in roadside is ceaselessly launched the transmission frequency that wireless notification signal (7) removes to tell the stop-light of automobile front with unified frequency of notification always, vehicle-mounted receiver apparatus (8) receives after the notification signal (7), automatically regulate receive frequency, thereby receive the traffic indicator signal and show.
At Fig. 2 is the planimetric map of a specific embodiment of four groups of wireless stop-lights of the present invention.Its difference with the prior art is characterised in that the present invention is not only having the traffic signals pilot lamp of different light colors, also increased a transmitting set, a receive frequency notifying device and a vehicle-mounted receiver apparatus, transmitting set and receive frequency notifying device send wireless traffic indicator signal and wireless notification signal respectively.These two kinds of wireless signals can indicate vehicle-mounted receiver apparatus to adjust receive frequency to receive wireless traffic indicator signal.
Claims (4)
1. a stop-light comprises redness, yellow, green indicating lamp, transmitting set, receive frequency notifying device, vehicle-mounted receiver apparatus.Stop-light not only sends wigwag, also send wireless traffic indicator signal, the receive frequency notifying device is constantly notified the transmission frequency of this traffic indicator signal of automobile of passing by the crossroad, vehicle-mounted receiver apparatus changes receive frequency after receiving notification signal, receives wireless traffic indicator signal and shows.It is characterized in that: on the basis of existing stop-light, increased transmitting set, receive frequency notifying device and vehicle-mounted receiver apparatus.
2. stop-light according to claim 1 is characterized in that: transmitting set sends wireless traffic indicator signal.
3. stop-light according to claim 1 is characterized in that: the receive frequency notifying device sends the transmission frequency that the wireless notification signal is told the mechanical transport pilot lamp.
4. stop-light according to claim 1 is characterized in that: vehicle-mounted receiver apparatus changes receive frequency after receiving notification signal, thereby receives only the wireless signal of the stop-light of front, is not subjected to the interference of other stop-lights.
