基于最优路径的无线语音泊车诱导系统研究

摘要

研究了一种用于大型停车场内的全程无线语音泊车诱导系统,诱导车辆用最少时间找到停车位,提高停车场泊车效率.通过激光对射装置检测车位状态,采用C8051F020单片机将检测到的车位信号进行处理,结合E-link网络数据传输器将单片机接入网络,实现车位信息的网络传输.开发了停车场泊车管理系统,实时显示车位使用状态.设计了由凌阳SPCE061A单片机和NRF24L01无线收发芯片构成的语音系统,对可用于最短泊车路径搜索的A*算法进行改进和仿真研究,并提出了无线语音泊车诱导方法.%Wireless voice parking guidance system in large parking lots is discussed in the paper. It spends the least time in finding parking spaces and improves efficiency of parking laser shooting devices are used to detect parking spaces. Parking signals detection is processed by C8051F020 single chip microcontroller. E-link network data transmission makes SCM access to network. Parking information is transmitted by network. Parking spaces are displayed in parking management system with real-time. Voice system is made by Sunplus of SPCE061A and NRF24L01 wireless transceiver chip. The methods of wireless voice parking guidance are discussed. Improvements and simulation are done for A* algorithm, it can be used for search of the shortest parking path.
