为了满足自动灌溉施肥的要求,开发了一款数据采集控制系统。以ARM处理器为核心,设计了数据采集和控制模块。各模块之间通过485总线连接,采用标准的MODBUS协议通信。根据系统软硬件环境定制了μC/OS-Ⅱ操作系统和文件系统。该系统实现了多任务的有效调度,大容量的数据存储以及远程网络访问。此系统已经应用于灌溉施肥的控制,并且能够根据用户的设置很好的完成施肥任务。
In order to meet the requirements of automatic irrigation and fertilization, a data acquisition control system has been developed. ARM processor as the core, designed the data acquisition and control module. Each module is connected by 485 bus, using standard MODBUS protocol communication. According to the system hardware and software environment customized μC / OS-Ⅱ operating system and file system. The system enables effective scheduling of multi-tasking, large-capacity data storage and remote network access. This system has been applied to the control of irrigation and fertilization, and can be completed according to the user’s well to complete the task of fertilization.
