摘　　要：为了解决家庭内部多点数据采集与智能监控问题,本文设计并实现了一种基于物联网的室内数据采集监控系统。整个系统以ARM Cortex-M3为核心处理器,以LORA模块和WIFI模块为无线通信设备,以LCD显示屏为数据显示端,接入多路无线传感器节点,每个节点接入多路传感器和控制器件,用于数据采集、控制、显示和上传。为了增加系统的实用性,加入万年历功能,通过获取网络时间或者本地时间为万年历提供时间数据。将系统部署于室内并进行测试,实验结果表明,整个系统的响应时间较短,在小于0.35 s的时间可以完成对数据的采集和上传;增加网络节点数量,系统可以准确识别并自动完成数据的采集、上传和设备控制,无丢失数据包情况。整个系统具有较高的实时性、稳定性和安全性,能够较好地满足室内数据采集与智能控制的需求。In order to solve the problem of multi-point data acquisition and intelligent monitoring in the family,an indoor data acquisition and monitoring system based on the internet of things is designed and implemented.The whole system takes ARM Cortex-M3 as the core processor,LORA module and WIFI module as the wireless communication equipment,LCD screen as data display terminal,and multi-channel wireless sensor nodes.Each node is connected with multi-channel sensors and control devices for data acquisition,control,display and upload.In order to increase the practicability of the system,the calendar function is added to provide time data for the calendar by acquiring network time or local time.The system is deployed indoors and tested.The experimental results show that the response time of the whole system is short,and the data acquisition and upload can be completed in less than 0.35 s.With the increase of the number of network nodes,the system can accurately identify and automatically complete the data acquisition,upload and equipment control without losing data packing.The whole system has high real-time,stability and security,and can better meet the needs of indoor data acquisition and intelligent control.
