摘　　要：针对机械式手动车位锁使用不便,以及当前单地磁传感器检测的智能车位锁容易受到相邻车位车辆进出或停放不规范干扰,出现误检问题等弊端,为提高车位锁对车位上的车辆检测的准确率,对现有的自动车位锁做出改进,提出了一种基于BLE技术的多种测量方法相结合的智能车位锁实现方法。该智能车锁可通过蓝牙模块进行信息传输及车辆定位,将定位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,同时可以实现手机APP推送开锁校验码。Aim at the inconvenience of the traditional manual operation parking lock and the current intelligent 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 intelligent parking lock is improved,implementation method of intelligent parking lock based on the fusion of geomagnetic sensor and BLE technology is proposed.The intelligent parking lock can transmit and locate information through the BLE 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.It can realize the unlock check code pushed by mobile APP.
