摘要
针对企业、小区等产权单位管理的井盖数量规模不大但需求灵活的特点,提出了一款基于Lora+WiFi进行组网的低成本井道监测系统.该系统以STM32单片机为主控器、采用Lora组网技术实现井盖间的无线数据传输、采用WiFi模块进行远程数据传输及数据上传云端.通过硬件设计与软件编程,实现多点井盖角度变化、供电状态、井道内气体浓度、液面深度等信息的监测,利用手机APP对系统进行监测和控制,以轮循方式实现井盖终端与云端的数据上传与命令下达.通过对实物系统进行测试,结果表明该系统能够实现对多个井盖点环境参数的有效监测.
Abstract
A low-cost wellbore monitoring system based on Lora+WiFi networking is proposed to address the small-scale but flexible demand of manhole covers managed by property right units such as enterprises and communities.With the STM32 microcontroller as the main controller,this system adopts Lora networking technology to achieve wireless data trans-mission between manhole covers,and WiFi modules for remote data transmission and data uploading to the cloud.By hardware design and software programming,the monitoring of the information about the multi-point manhole cover angle changes,pow-er supply status,gas concentration in the wellbore,liquid level depth,and so on can be achieved.The mobile apps is used to monitor and control the system,and the data upload and command issuance between the manhole cover terminal and the cloud are realized in a round-robin manner.The results of testing the physical system show that it can effectively monitor the envi-ronmental parameters of multiple manhole cover points.
