Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] An adaptive receiving device for LED car light communication, which receives light signals emitted by other vehicles through LED car lights (which can be front car lights or rear car lights). This device is figure 1As shown, it includes a photoelectric conversion module, a microcomputer processor 4 and a microelectromechanical mechanism 3. The photodiode array 1 in the electrical conversion module is installed on the microelectromechanical mechanism 3 as a device for receiving and converting optical signals. In the form, the photodiode array 1 can receive light signals in a large angle range, and output multiple electrical signals corresponding to the number of diodes, and then amplify the standard signals into the microcomputer processor 4 through the multi-channel amplifying circuit 2 . Since each photodiode has a different position relative t...

Abstract

The present invention relates to visible light communication technology in vehicle network, and provides an adaptive reception device for LED vehicle light communication. The device includes a photoelectric conversion module and a microcomputer processor connected with the photoelectric conversion module. The photoelectric conversion module includes a photodiode array for receiving light signal and a multi-channel amplification circuit. The output end of the photodiode array is connected with the microcomputer processor via the multi-channel amplification circuit. The photodiode array is arranged on a micro-electromechanical mechanism, and the microcomputer processor controls and connects with the micro-electromechanical mechanism. The present invention also provides an adaptive reception method for LED vehicle light communication. The method uses the photodiode array to receive and convert the light signal, and uses a disturbance observing method to calculate the best receiving angle, thus realizing tracking the light signal emission source. The solution solves the problems of the reliability and stability of the reception of the light signal in the prior art.

Description

technical field [0001] The invention relates to the visible light communication technology in the Internet of Vehicles, in particular to an adaptive receiving device and method for LED vehicle light communication. Background technique [0002] LED lighting wireless communication has great development prospects because of its safety, economy and high speed. Although this technology is still in its infancy and exploration abroad, its application prospects are very promising. It can not only be used for indoor wireless access, but also It can provide a new method for mobile navigation and positioning of urban vehicles. Car lighting basically uses LED lights, which can form communication links between cars and traffic control centers, traffic lights to cars, and cars to cars. This is also the development direction of LED visible light communication in intelligent transportation systems. [0003] As disclosed in CN 202524390, an LED communication lighting device and a motor vehi...
