摘　　要：针对传统手动车位锁使用不便,以及现有智能车位锁的单地磁传感器在对车位上的车辆检测时容易受到相邻车位车辆干扰,出现误检问题等弊端,为提高停车位车辆检测的准确率,对现有的智能车位锁做出改进,提出了一种基于超宽带(Ultra Wide-band,UWB)技术的智能车位锁实现方法。该智能车锁可在车主靠近时通UWB模块进行信息传输及定位,将测距结果与地磁信号融合来提高车辆的检测准确度,实现智能车位锁精准控制。Aim at the inconvenience of the traditional manual operation parking lock and The current intelliget parking lock threshold based single geomagnetic detection method is easy to be interfered by the adjacent parking space vehicle when performing vehicle detection,resulting in high missing detection and false detection probability.In order to improve the accuracy of parking vehicle detection,the current intelliget parking lock is improved,Implementation method of intelligent parking lock based on the fusion of geomagnetic sensor and ultra wideband(UWB)technology is proposed.The intelliget parking lock can transmit and locate information through the UWB module when the owner approaches.and the ranging result is combined with the geomagnetic signal to improve the detection accuracy.Realize precise control of intelligent parking lock.
