基于LoRaWAN的智能园区管理系统

Intelligent Park Management System Based on LoRaWAN

对于现在物联网传输技术存在传输距离和功耗上无法兼得的问题,提出并实现一种新的智能园区管理系统,该系统基于LoRa技术,系统分为数据采集端、LoRaWAN和管理软件端三部分,在数据采集端,采集节点收集停车场和火灾报警装置中超声波和火焰传感器信息,然后发送给LoRa网关节点,通过串口发送给管理软件端,并对停车场车位信息进行更新和对火灾的实时警报操作。该系统克服Wi-Fi传输距离短与ZigBee穿透能力差的缺点,满足信息低功耗且远距离的传输要求,对园区管理的智能化有很强的实用性。

Proposes and implements a new intelligent park management system, aiming at the problem of the transmission distance and power consumption of the Internet of Things transmission technology. The system is based on LORA technology, is divided into three parts： data acquisition port, LoRaWAN and management software port. At the data collection port, the collection node collects the ultrasonic and flame sensor information in the parking lot and the fire alarm device, and then sends it to the LoRa gateway node, sends it to the management software terminal through the serial port, and updates the parking space information and the real-time alert for fire. The system overcomes the shortcomings of Wi-Fi short transmission distance and ZigBee poor penetration capability, meets the requirements of low power consumption and long-distance transmission, and has strong practicability for intelligent management of campus management.
