温室环境智能化检测与控制系统设计摘 要为了实现温室的智能化管理，设计了一种基于 STC15W4K56S4 的温室环境智能化检测与控制系统，由数据采集系统、过程控制系统、上位机界面组成。通过数据采集系统检测温室环境中各变量的值，由单片机读取，对数据进行处理。过程控制系统由补光灯、加热器、电动通风窗等组成，当温室中的变量超出设定的范围时，由单片机发出命令，触发警报系统，并将信号送给过程控制系统，进行降温、通风、遮阳等操作。上位机界面由 python 编写，上位机通过无线数传模块与单片机进行串口通讯，对温室环境中各变量的值进行实时显示和监控。且该系统设置了智能门禁系统，实现了温室进出人员的科学化管理。关键词： 多变量 过程控制 智能门禁 上位机IDesign of Intelligent Detection and Control System for Greenhouse EnvironmentAbstractIn order to realize the intelligent management of greenhouse, a greenhouse environment intelligent detection and control system based on STC15W4K56S4 is designed, which is mainly composed of data acquisition system, process control system and upper computer interface. The value of each variable in the greenhouse environment is detected by the data acquisition system, which is read by the single chip microcomputer and processed. The process control system consists of supplementary light lamp, heater, electric ventilation window, etc. When the variables in the greenhouse exceed the set range, the MCU will issue the command, trigger the alarm system, and send the signal to the process control system for cooling, ventilation, shading and other operations. The upper computer interface is written by python. The upper computer communicates with the single chip microcomputer through serial port through wireless data transmission module, and displays and monitors the values of various variables in the greenhouse environment in real time. In addition, the system is equipped with an intelligent access co...
