多点大棚环境参数检测系统的设计

Design of Greenhouse Multi-spot Environment Parameters Measurement System

在提倡现代化农业的大背景下,为了帮助国内智能温室更好地发展与普及,对多点环境参数检测系统进行了研究。综合了传感器技术、嵌入式技术、以及通信技术实现了对大棚内温度、湿度、光照强度以及侧窗开启角度的检测,执行器控制、数据存储和分析、人机交互的功能。重点介绍了传感器电路的设计、测点上单片机的编程、上位机和监控中心的功能和实现方式,以及他们之间通信的接口。经过测试,测得的实验数据满足设计精度、运行稳定、可靠性高、成本低,有利于进一步的推广。

Under the background of promoting modernization agriculture, in order to help the development and popularization of domestic intelligent greenhouses, this paper studies the system of multi-spot environment parameters measurement, which makes use of sensors, embedded system and communication, and realizes the measurement of temperature, humidity, illumination intensity and the open angle of the side windows, the control of the executors, data storage and analysis, the function of man - computer interaction. This paper specially introduces the design of sensor circuits, the programming of one chip computer, the function and the realization of upper computer, monitor center, and the communication interface between them. The test results meet the design requirements with high quality and low cost, and the system can be popularized.
