【摘要】 针对传统手动车位锁使用不便以及现有智能车位锁功耗大、安全系数低等弊端,本文旨在利用低功耗蓝牙技术来设计一个感应式智能车位锁。整个系统主要有控制模块、蓝牙电子标签、地磁车位检测模块、电源管理模块和手机五部分构成。其中蓝牙电子标签和控制模块主要由低功耗蓝牙芯片nRF51822组成,实现车位锁密钥发送、识别以及对车位锁的控制;地磁车位检测模块主要由HMC1021S组成,实现对车位状况的检测;电源管理模块主要负责工作电压转换和电量检测。更多还原

【Abstract】 Aim at the inconvenience of the traditional manual operation parking lot barrier and the high power consumption, unsafe of the current intelligent parking lot barrier, this paper aims to design an inductive and intelligent parking lot barrier. The whole system is composed of the electronic tag of Bluetooth,the geomagnetic detection module of carport, the module of power management and system control and mobile. The electronic tag of Bluetooth and the module of system control is mainly composed of nRF51822,and implement the secret key sending and recognition, and the parking lot barrier control.The geomagnetic detection module of carport is mainly consist of HMC1021S, and realize the detection of carport condition. The module of power management is mainly in charge of the conversion of work voltage and electric quantity detection.更多还原
