基于以太网的分布式温湿度监控系统

摘要

Traditional temperature and humidity monitoring system adopts RS485 transmission mode in general,with a small control range and complicated wiring limitations.In order to achieve temperature and humidity monitoring of large-scale cross regional,a distributed temperature and humidity monitoring sys-tem based on Ethernet is designed and developed from the perspective of a monitoring distance and stable performance.In this system,hardware circuit module and software interface are developed respectively.At present,the system has been applied in pharmaceutical products storage management,granary manage-ment,laboratory monitoring,etc.%传统温湿度监控系统多采用 RS485传输方式，具有控制范围小和布线繁琐等局限性。为了实现大规模跨地域的温湿度监控，该文从监控距离远、性能稳定的角度出发，设计并研制了一套基于以太网传输的分布式温湿度监控系统，分别开发了温湿度监控的硬件模块和软件界面。目前该系统已应用于医药品存储管理、粮库管理、实验室监控等多个领域。
