【Specific embodiment】
Refer to Figure of description 1 to shown in accompanying drawing 3, this utility model is that a kind of garage based on visible light communication is real
When communication system 7 and communication means, relative with automobile master control system 6 connect, it is by some optical transmitter and receivers 1, controller 2, information write
A few part such as device 3, information read device 4 and memorizer 5 forms;Wherein, described controller 2 respectively with each optical transmitter and receiver 1, letter
Breath writing station 3, information read device 4 and memorizer 5 connect.Described controller 2 is also connected simultaneously with automobile master control system 6
Communication.
Specifically, described optical transmitter and receiver 1 includes manipulator 11, driver 12, LED array 13, optical receiver 14 and demodulation
Device 15.To car outgoing deliver letters breath when, described manipulator 11 receives the coded data that controller 2 sends, and is converted into
Level modulated signals, described driver 12 drives described LED array 13 to car emission pair under the control of level modulated signals
The visible or infrared light signal answered.From car during receive information, described optical receiver 14 receives visible ray or red from car
Outer optical signal, and it is converted into the signal of telecommunication, then coded data is converted into by described demodulator 15, and it is sent to control
Device 2.
Described controller 2 between optical transmitter and receiver 1 and information write-in device 3/ information read device 4, and coordinate them it
Between correspondence;To car outgoing deliver letters breath when, controller 2 obtains information or instruction from information write-in device 3, and is transmitted
To optical transmitter and receiver 1;From car during receive information, controller 2 is from optical transmitter and receiver 1 receive information, and is transferred to information read device
4.
Further, people are write hope and are sent to the letter outside car by optical transmitter and receiver 1 by described information writing station 3
Breath.For example, people can want the information of reception and registration by microphone typing, or selects to pre-deposit in memorizer by keyboard
Information etc., now microphone or keyboard are exactly described information write-in device 3.
Further, people read the information that optical transmitter and receiver 1 receives from car by described information reading device 4.For example,
People can hear sound by speech ciphering equipment, or sees Word message etc. by vehicle-mounted LCDs, now voice
Equipment or liquid crystal display screen are exactly described information read device 4.
As follows using the above-mentioned garage real-time communication method based on visible light communication:
1) certain car to car outgoing deliver letters breath when, controller 2 obtains information or instruction from information write-in device 3, and is passed
Give optical transmitter and receiver 1;The manipulator 11 of optical transmitter and receiver 1 receives the coded data that controller 2 sends, and is converted into level tune
Signal processed, driver 12 drives described LED array 13 to the corresponding visible ray of car emission under the control of level modulated signals
Or infrared signal;
2) from car during receive information, the optical receiver 14 of optical transmitter and receiver 1 receives visible or infrared light signal to another car,
And it is converted into the signal of telecommunication, then coded data is converted into by demodulator 15, and it is sent to controller 2;Controller 2 is from light
Terminal 1 receive information, and it is transferred to information read device 4.
This utility model be used for automobile 8 when, before automobile 8, rear and side all can install one or more described
Optical transmitter and receiver 1, for above, the automobile 8 of rear and side carry out real-time Communication for Power.For example, when the automobile head-on coming in front is beaten
High beam, had a strong impact on in-car driver the visual field when, driver can bark out " please don't long switch-on distance light " by microphone,
Or press A key on lower keyboard to call the information of " please don't long switch-on distance light " in pre-existing memorizer 5, thus by front
Information is sent by optical transmitter and receiver 1 with optical signal form.The automobile 8 head-on coming captures optical signal and by car by front optical transmitter and receiver 1
Carry speech ciphering equipment to send, so that its driver hears the information of " please don't long switch-on distance light ".In the same manner, front optical transmitter and receiver can also be passed through
1 sends information such as " overtaking other vehicles, please avoid " to preceding vehicle;Or " turning, please avoid " is sent to both sides vehicle by sidelight terminal 1
Etc. information;And rearwards vehicle sends information such as " in decelerations it is noted that " or " in reversing it is noted that " by rear optical transmitter and receiver 1.
Above specific embodiment is only preferred embodiment of the present utility model, not in order to limit this utility model,
