Zhang Qiong1,2,Zhao Chunjiang1,Wang Cheng1,Xu Zhilong1(1.National Engineering Research Center for Information Technology in Agriculture,Beijing 100097,China;2.Department of Automation,University of Science and Technology of China,Hefei 230026,China)  
In order to meet the needs of the automatic fertigation and its application,a data acquisition control system was developed.Taking ARM processor as nucleus,the data acquisition module and the control module were designed.Each module was connected via RS-485 bus and communicated based on Modbus protocol.According to the hardware and software environment,μC/OS-II operating system and the file system were customized.Effective multi-task scheduling and large capacity of data storing,as well as remote access network,were realized in this system.The system was already applied in the control of fertigation,and could fulfill the task with high efficiency according to the setting.
