基于HORNER OCS的灌溉施肥智能化控制系统

为全面提升系统对灌溉、施肥操作指令的控制精准性，设计基于HORNER OCS的灌溉施肥智能化控制系统。利用灌溉施肥过程向量，确定协同控制定义式，完成系统的协同控制能力建模。在此基础上，连接ZigBee无线模块与单片机控制芯片，通过设置灌溉传感器与施肥传感器的方式，明确指令信息在系统中的传输位置，达到精准控制操作指令的目的，再借助智能化电平转换电路，完成系统执行设备选型处理。在此应用背景中，选取HORNER OCS通讯协议，进行灌溉施肥组态节点连接，实现HORNER OCS组态软件设置，完成基于HORNER OCS的灌溉施肥智能化控制系统设计。选取番木瓜作为监测对象，分析控制数据可知，应用灌溉施肥智能化控制系统后，在灌溉、施肥控制指令的促进下，植株根系与叶片的生长速率明显加快，由此证明智能化控制系统确实具备更为精准的指令控制能力。

Intelligent Control System of Irrigation and Fertilization Based on HORNER OCS

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.
