Abstract: With the large-scale development of greenhouse, the intelligent detection and control system of greenhouse has been updated and higher. In the modern intelligent detection and control system, whether a system can monitor and control the greenhouse environment parameters intelligently and accurately determines the development prospect of the system. In this paper, AT89S52 single-chip microcomputer was used to design a system which could accurately measure and control the parameters of carbon dioxide concentration, temperature and humidity in greenhouse, and the components of the system and some main components used in each part were briefly described.
Keywords: single chip microcomputer;embedded system;greenhouse environment;measurement and control system
1 研究背景
在當(dāng)前現(xiàn)代溫室逐漸呈現(xiàn)出規(guī)模化與集約化發(fā)展趨勢(shì)的大背景下[1],針對(duì)溫室智能化管理提出了高標(biāo)準(zhǔn)的要求。所以,如果想要實(shí)現(xiàn)溫室、大棚高產(chǎn),則需要準(zhǔn)確監(jiān)測(cè)溫室環(huán)境數(shù)據(jù),包括空氣溫濕度及一氧化碳濃度等。
溫室環(huán)境控制具體指的是在免受外部氣候條件影響的基礎(chǔ)上,借助改變溫室內(nèi)部環(huán)境因子為作物成長提供良好的環(huán)境條件,所涉及的控制技術(shù)由兩部分構(gòu)成,即硬件結(jié)構(gòu)與控制算法。由于單片機(jī)控制系統(tǒng)具有能全局管理、操作簡單、價(jià)格低廉等一些優(yōu)點(diǎn),所以其在溫室環(huán)境測(cè)控中得到了廣泛應(yīng)用。

2.1 系統(tǒng)總體設(shè)計(jì)
系統(tǒng)下位機(jī)的核心為ATMEL公司生產(chǎn)的AT89S52單片機(jī),其具備在線調(diào)試功能。應(yīng)用本系統(tǒng)可以實(shí)時(shí)監(jiān)測(cè)溫室、大棚中的空氣溫濕度及一氧化碳濃度等,并借助串口與上位機(jī)和主芯片進(jìn)行通訊。……
