摘要
为了提高智能温室的自动化水平,设计了以PIC18F97 J60单片机为核心的检测控制系统。系统采用先进的以太网供电技术,通过网线连接到作为以太网供电设备的中继站,从中继站得到电源。同时,系统通过对影响温室的光照、湿度、温度和二氧化碳等环境因素进行收集,通过网线电缆发送给上位机DSP并从DSP得到相应的控制策略。系统实现了信号线和电力线的合二为一,便于分布式、网络化布局,提高了现场应用能力。
To improve the automatic level of intelligent greenhouse,the detection and control system with the kernel of PIC18F97J60 microcontroller was designed.The system adopted the advanced POE（power over Ethernet） technology,connected the power sourcing equipment,intermediate site with Ethernet cable and got power from it.At the same time,the system can gather environment factors such as light intensity,humidity,temperature and carbon dioxide.The system sends those messages to upper computer DSP,and then gets control strategy from it through Ethernet cable.The system gets signal lines and power lines together.It＇s suitable for distributed,networked layout and improves field application ability.
