摘要
实际中常见的烟花仓库温湿度监测系统存在成本大、数据滞后等问题,用户必须到现场测量获取温湿度数据,过程繁琐且无法及时反馈或在危险发生前进行预警。鉴于此研究了一种烟花仓库温湿度灰色预警系统。该系统基于TDMA构建LoRa主从网络,可在复杂情况下将仓库的温湿度数据即时发送给用户,并在用户界面对未来某时刻的温湿度进行灰色预测,使用户能及早发现。通过反复测试,该系统能及时上报烟花仓库温湿度,且灰色预测偏差小。
The common firework warehouse temperature and humidity monitoring system in practice has problems such as high cost and data lag.Users must go to the site to obtain temperature and humidity data.The process is cumbersome and cannot timely feedback or early warn before danger occurs.Based on this research,a gray fireworks warehouse temperature and humidity early warning system is built.This system builds a LoRa master-slave network based on TDMA,which can send warehouse temperature and humidity data to users in complex situations timely,and the user interface can make gray predictions to enable users to discover early.Through repeated testing,the system can report the temperature and humidity of the fireworks warehouse in time,and the gray prediction deviation is negligible.
