Abstract:In order to improve the control accuracy of irrigation and fertilization operation instructions, an intelligent irrigation and fertilization control system based on HORNER OCS was designed. By using the process vector of irrigation and fertilization, the definition of collaborative control is determined, and the collaborative control capability of the system is modeled. On this basis, connected the ZigBee wireless module with the MCU control chip, through setting up the irrigation sensor and fertilizer sensor, the transmission position of instruction information in the system is clear, so as to achieve the purpose of precise control of operation instructions. Then, with the help of intelligent level conversion circuit, the selection and processing of the system execution equipment is completed. In this application background, the HORNER OCS communication protocol is selected to connect the nodes of irrigation and fertilization configuration. The configuration software of HORNER OCS is set up, and the intelligent control system of irrigation and fertilization based on HORNER OCS is designed. The papaya was selected as the monitoring object and the control data were analyzed. The results showed that the growth rate of root and leaf of plant was obviously accelerated with the promotion of irrigation and fertilization control instructions after applying the intelligent control system of irrigation and fertilization, which proved that the intelligent control system indeed had more precise command control ability.
