摘要
为了满足温室控制系统下位机的通信、数据采集以及控制动作的功能需求,基于系统架构设计和硬件构成,确定了RS485通信帧格式、地址分配方案以及通信超时处理措施,设计了数据采集和控制软件。系统投入运行以来,数据通信采集精度都达到了设计要求,效果良好。
In order to meet the slave control system of greenhouse＇s communication,data acquisition and control functional requirements.Based on the system Architecture design and hardware configuration to determine the RS485 communication frame format,the address allocation scheme and the communication time-out treatment measures,Design the software of data acquisition and control.After the system put into operation,Accuracy of data communication is very good acquisition to meet the design requirements.
