基于可見光通信的隧道車輛定位系統(tǒng)設(shè)計
[Abstract]:With the speeding up of highway construction in our country, especially the development of highway in mountain area, the number of tunnels is increasing rapidly. Because the tunnel has the characteristics of narrow internal space, complex structure and strong sealing, the GPS system has lost its positioning function in the tunnel interior, which has brought some obstacles to the safety and smooth navigation of the automobile. Therefore, we need a new technology that does not rely on GPS signal to realize vehicle positioning in tunnel. In the existing Wi-Fi, Bluetooth, ZigBee and other short-range wireless positioning technology, such as low precision, serious consumption of wireless spectrum resources, high cost of implementation of the project, and the complex layout of the system, As one of the main applications of visible light communication technology, visible light positioning technology can make full use of the existing lighting facilities, and it can also obtain high positioning accuracy. Based on the laboratory project, this paper mainly studies the tunnel vehicle positioning system based on visible light communication from three aspects: the characteristic research of tunnel visible light communication channel, the design of communication node, and the positioning algorithm. Firstly, based on the characteristics of LED, the luminescence principle, electrical and optical characteristics and emission model of LED are described in detail. According to the actual environment of the tunnel, the visible light communication link is analyzed, and the layout of the light source is designed and simulated by using Matlab, so that the average luminance of the illumination area can meet the lighting and communication requirements of the system. Then, according to the requirements of the system, the hardware circuits of anchor node and mobile acquisition node are designed. The anchor node can transmit the data information in the form of light without affecting the normal lighting. The mobile acquisition node acquires the optical signal, amplifies the RSS signal and restores the data information by shaping. At the same time, the communication of the system and the design of the control unit software are realized based on the FPGA module. Finally, the design of visible light location algorithm based on trilateral localization is proposed and implemented. The "RSS- distance" empirical formula is obtained by fitting the received RSS signal in the off-line modeling phase. In the stage of on-line localization, three groups of RSS data are selected by evaluation, then the final localization results are obtained by combining the empirical formula of "RSS- distance" and the trilateral localization algorithm based on maximum likelihood estimation.
