基于窄带物联网的智能车位锁管理系统设计

Design of Intelligent Parking Lock Management System Based on Narrowband Internet of Things

针对当前车位锁存在的操作不便、续航时间短、检测准确率低等弊端,设计一种基于窄带物联网的智能车位锁管理系统.该系统以STM32为控制核心,利用三轴地磁传感器和相邻车位抗干扰算法实现对车位状态的准确判断,并通过窄带物联网通信技术将车位状态信息实时发送到云平台,用户利用蓝牙与手机App相连实现车位的预定、开关锁及故障报修等功能.经测试,该系统能够准确地检测车位占用情况,且传输时延小,在车位智能化管理方面具有一定的应用价值.

Aiming at the disadvantages of current parking space locks,such as inconvenient operation,short battery life and low detection accuracy,an intelligent parking space lock management system based on narrowband Internet of Things is designed.The system takes STM32 as the control core,uses three-axis geomagnetic sensor and adjacent parking space anti-jamming algorithm to accurately judge the parking space status,and sends the parking space status information to the cloud platform in real time through the Narrowband Internet of Things communication technology.The mobile app is connected with the Bluetooth to realize the functions of parking space reservation,switch lock and fault repair,et al.After testing,the system can accurately detect the occupancy of parking spaces,and the transmission delay is small,which has certain application value in the intelligent management of parking spaces.
