基于ESP32的大田水肥一体化控制系统设计

Design of integrated field water and fertilizer control system based on ESP32

为解决在传统大田作物种植过程中的水肥一体化集成度低、成本高、远程监控与管理困难的问题,设计一个能够远程控制的水肥一体化控制系统。该系统包含主控模块、数据采集模块、执行装置模块和远程控制模块,实现了对水肥一体化的全面控制。通过数据采集模块获取EC值、肥液流量等数据,主控模块主要进行智能化分析,通过执行装置模块实现对水肥的自动施用,再使用远程控制模块对数据进行存储,并允许用户通过远程方式监控和调整系统工作状态。经测试,该系统在本地控制时响应耗时平均为16.5 ms,远程控制响应平均耗时为1290 ms,远程控制与本地控制所显示的系统工作状态以及传感器数据实时同步。该系统设计为大田作物水肥一体化管理提供了一种先进、高效的解决方案,提高了水肥一体化的集成度,降低了成本,并解决了远程监控难题。

In order to solve the problems of low integration,high cost and difficult remote monitoring and management of water and fertilizer integration in the process of traditional field crop planting,a water and fertilizer integration control system that can be remotely controlled is designed.The system includes main control module,data acquisition module,actuator module and remote control module,which can realize the comprehensive control of water and fertilizer integration.The EC value,fertilizer flow rate and other data are obtained by means of the data collection module,while the main control module is used to mainly conduct intelligent analysis and automatically application water and fertilizer by means of the execution device module.The remote control module is then used to store the data and allow users to remotely monitor and adjust the system′s working status.After testing,the average response time of the system during local control is 16.5 ms,and the average response time for remote control is 1290 ms.The system′s working status and sensor data displayed by remote control and local control are synchronized in real time.The designed system can provide an advanced and efficient solution for integrated management of water and fertilizer in field crops,which can improve the integration degree of water and fertilizer integration,reduce costs,and solve the problem of remote monitoring.
