Automatic parking guidance system based on ultraviolet light communication

针对现有泊车引导系统在车辆引导过程中动态规划效率不高、在不同泊车环境下兼容性差,由此给泊车引导系统可靠性带来较大不利影响的问题,设计了兼容多种泊车环境的基于"日盲"紫外光通信技术的泊车引导系统,在预处理模块中采用路径规划算法提升动态规划效率,利用"日盲"紫外光通信技术对环境兼容性强、不易受环境影响的特点,改善泊车引导系统的兼容性。实验表明:该系统有效地减少了路径动态规划时间、可在多种泊车环境中保证单节点4m的有效通信距离,可满足泊车引导系统的基本要求。

Aiming at the problem that the existing parking guidance system is not efficient in dynamic planning during vehicle guidance and has poor compatibility under different parking environments, that has a great adverse effect on the reliability of the parking guidance system. This paper designs the parking guidance system based on "day blind" ultraviolet light communication technology in parking environment, adopts path planning algorithm in the preprocessing module to improve dynamic programming efficiency, and uses "day blind" ultraviolet communication technology which has strong environmental compatibility and is not susceptible to the environment to improve the compatibility of the parking guidance system. Experiments show that the system can effectively reduce the path dynamic planning time and ensure the effective communication distance of 4 meters in a single parking environment, which can meet the basic requirements of the parking guidance system.
