摘要
针对温室环境监控的需要,设计了一种基于RS-485总线和短距离无线通信方式的温室环境监控系统。给出了系统硬件的实现方法,在此基础上根据温室环境监控的具体应用提出了一种多点传输数据的通信协议。初步试验表明,系统具有可扩展性强、成本低等特点,能够对温室内部的环境因子进行有效的监测,较好地满足温室环境监控的应用需求。
Based on the RS-485 bus and the short distance communication mode,a greenhouse environment monitoring system was designed to collect the main environmental parameters,such as temperature and humidity,etc.Firstly,the hardware of the greenhouse climate system is given.Secondly,on the basis of the designed hardware,a multiple-points transmission protocol is introduced in detail.Preliminary experimentations showed that the system met the application requirements of greenhouse monitoring excellently and has a flexible structure and low cost.
