As shown in the figure: control center utilizes the communication network line to be connected with transmitting and receiving device, and described control center comprises a MCU micro controller system and order supervisory keyboard, and a described MCU micro controller system is used for the mode of operation of monitor command supervisory keyboard; Described transmitting and receiving device comprises the 2nd MCU micro controller system, transmitter pulse modulation circuit and received pulse modulation circuit, and the 2nd MCU micro controller system is used to monitor the mode of operation of transmitter pulse modulation circuit and received pulse modulation circuit; Connect the optical transmitting set that is integrated in the car light at the mouth of transmitter pulse modulation circuit, connect the optical receiver that is integrated in the car light at the input end of received pulse modulation circuit;
When the order supervisory keyboard sends instruction, the one MCU micro controller system is encoded to described instruction and is sent to transmitting and receiving device by communication network, transmitter pulse modulation circuit in the transmitting and receiving device is modulated the optical signal that optical transmitting set sent that is integrated in the car light, and command signal is carried in the optical signal after the modulation sends by optical transmitting set; After optical receiver in being integrated in car light was received described optical signal, the received pulse modulation circuit in the transmitting and receiving device carried out demodulation to optical signal, again the optical signal after the demodulation is sent to control center by communication network.Described control center comprises that also LCM shows voice warning circuit, and after control center carried out interpretation to the optical signal that receives, demonstration and voice suggestion or forwarding were taked in decision again.
Described car light comprises headlight and Rear lamp for vehicle; Described optical transmitting set and optical receiver are arranged on headlight and the Rear lamp for vehicle simultaneously.
Described car light can be adopted as the LED car light, described LED car light comprises the some LED illuminating lamps 1 of array in horn-like reflection shield 2 bottoms, and be positioned at the luminous intensity distribution plate 3 of horn-like reflection shield 2 open ends, at LED illuminating lamp 1 interbody spacer optical receiver 6 and optical transmitting set 5 are set.Described car light also can adopt traditional thermal light source lamp, and described thermal light source lamp comprises reflector 8 and is positioned at filament thermal light source 7 on reflector 8 focuses, and is positioned at the luminous intensity distribution plate 3 of reflector 8 open ends; At filament thermal light source 7 and 3 of luminous intensity distribution plates support 9 is set, optical receiver 6 and optical transmitting set 5 are set on support 9.
Because filament thermal light source car light has stronger thermal inertia, can't work under higher modulating frequency, but luminous intensity is big, is suitable for the less simple instruction of information content long-distance transmissions on a large scale.Semiconductor type solid luminescence source (LED etc.) volume is little, frequency response is high, but luminous intensity is lower slightly, is suitable for the transmission of large information capacity complicated order more among a small circle.Native system can adopt LED, LD, OLED, normal signal lamp, thermal light source illuminating lamp or their combination as signal emitting-source according to actual communication need difference in realization.In addition, in order to strengthen noiseproof feature, can also implement the emission of command signal by the mode that adopts the combination of multiple light courcess multiband.With following two example approach is example:
Embodiment one, LED car light scheme:
Along with the development and the widespread adoption of superhigh brightness LED technology, LED is used for lamp system and becomes a reality.Present LED car light is mainly used on the indication class light fixtures such as stoplight stop lamp, steering indicating light.Among semiconductor light-emitting-diode (LED) car light that this example approach is integrated in vehicle with the emission and the receiving system of communication system, because light-emitting diode has very high frequency response, only need the driving circuit of lamp system is carried out the requirement that suitable transformation can be satisfied the communication of large information capacity complicated order.
At this moment, feed circuit 4, the light distributing system of car light all can be fully utilized, and the unit design of car light also almost can not need be carried out too much modification and is used.Only need in car light some position that illuminating LED is replaced to communication with devices such as LDE or LD, (also illuminating LED can be directly used in the transmission of communication instruction in case of necessity) also installs receiving element additional and circuit gets final product in position.As shown in Figure 4.Transmit and receive the arrangement of element in car light, can mix to arrange also to be divided into the concentrated arrangement of different functional areas according to the luminous intensity distribution designing requirement with illumination component.According to different environments for use, radiated element can adopt the different wave length combination to be provided with, to improve the antijamming capability of system.
Embodiment two, and filament thermal light source car light adds quartz conductor communication light source package:
Filament thermal light source car light luminous intensity is higher, and car headlight and fog lamp still adopt this form at present basically.Because the thermal inertia of light source is used for communication and can only transmits the lower simple instruction of quantity of information, installs solid luminescence light source and receiving device in car light additional, can solve the frequency response problem preferably.As shown in Figure 6.The form that filament thermal light source car light adopts parabolic reflector to add the luminous intensity distribution plate usually realizes the illuminating effect of requirement, before lamp holder,, can not bring influence by reflector reflection back outgoing basically to illuminating effect again by of the luminous energy retroreflection of sphere reflection shield with the forward direction outgoing.Therefore as communication receiving/transmission device mounting support, only needing that the luminous intensity distribution plate is done the local improvement design can be integrated in the communication receiving/transmission device in the car light when keeping the original illuminating effect of car light this programme with the front end reflection shield.This example is not changing under the integrally-built situation of original lamp system, not only can realize the required optical property of receive-transmit system by the local improvement to the luminous intensity distribution plate, but but also can utilize the car light reflector to improve the response angle that signal receives.
The means of communication that native system provides not only have excellent adaptability and reliability, and good concealment, can prevent from effectively to monitor, and dust haze has stronger penetrating capacity to misty rain if adopt infrared-ray communication.Simultaneously, the form that adopts relaying to transmit has been extended the ranging coverage and the sphere of action of signal transmission, makes wireless optical communications be achieved in bigger spatial dimension.
