摘要
在农业生产过程中,落后的灌溉设施和粗放的管理制度导致人力成本高、水资源浪费、施水量不合理等情况发生,极大地限制了农业的发展,本文针对以上问题设计了一款基于STC89C52的灌溉控制器。首先,本控制器采用STC89C52系列微控制器作为硬件主控核心,在Keil u Vision5软件平台上使用C语言完成对硬件驱动程序的编写。控制器主要包括采集端、处理端、控制端和显示端四部分,其中用户通过显示端负责灌溉控制器与人进行的数据交互,,采集控制端负责数据采集、中控端复杂数据融合以及处理、控制端灌溉控制。最后,对硬件设备和数据进行测试,测试结果表明该灌溉控制器具有稳定性高、控制效果好、人力成本低等特点,还可为现代化农业提供大数据支持。综上,本文设计的基于STC89C52的灌溉控制器可实现数据监测与灌溉控制功能,通过自主灌溉决策将土壤湿度自动维持在预设的范围内,解决了传统的灌溉方式中存在的环境参数不可视、数据传输不稳定、施水量不合理、人力成本高以及仅凭人为经验判断灌溉等问题,具有一定的实际意义。

Abstract
Tn the process of agricultural production, backward irrigation facilities and extensive management system lead to high human cost, waste of water resources, unreasonable water application and other situations, which greatly limit the development of agriculture. This paper designs an irrigation controller based on STC89C52 for the above problems. First of all, this controller adopts STC89C52 series microcontrollers as the hardware main control core, and uses C language to complete the writing of hardware drivers on the Keil u Vision5 software platform. The controller mainly includes four parts: acquisition end, processing end, control end and display end. The user is responsible for the data interaction between the irrigation controller and people through the display end; the acquisition and control end is responsible for data acquisition, complex data fusion and processing in the middle control end, and irrigation control in the control end. Finally, the hardware equipment and data are tested. The test results show that the irrigation controller has the characteristics of high stability, good control effect, low labor cost, and can also provide big data support for modern agriculture. In conclusion, the irrigation controller based on STC89C52 designed in this paper can realize the functions of data monitoring and irrigation control, and automatically maintain the soil moisture within the preset range through the independent irrigation decision, which solves the problems existing in the traditional irrigation methods, such as invisible environmental parameters, unstable data transmission, unreasonable water application, high labor cost and judging irrigation only by human experience The question has a certain practical significance..
