【摘要】：本文結(jié)合生豬養(yǎng)殖要求和豬舍環(huán)境特點,在查閱了大量中英文獻(xiàn)的基礎(chǔ)上,總結(jié)出了影響豬只生長發(fā)育的四大環(huán)境因子——溫度、濕度、通風(fēng)、光照,同時對豬舍環(huán)境控制技術(shù)的歷史發(fā)展和現(xiàn)狀有了清晰的認(rèn)識。首先深入企業(yè)調(diào)查豬場存在的實際問題和征詢管理人員的需求,同時從工作人員那里了解小豬的生長曲線及不同階段的豬最適宜的成長環(huán)境;之后提出系統(tǒng)總體構(gòu)思,草擬了幾個可行性方案,經(jīng)過比對、甄別,篩選出了最佳方案;最后完成了硬件電路的設(shè)計及軟件設(shè)計(基于庫函數(shù)的開發(fā)環(huán)境)。經(jīng)過模擬測試,主控制器能精確地測量各環(huán)境變量,并實現(xiàn)對多種輸出設(shè)備的控制。本文將現(xiàn)代控制理論、傳感器技術(shù)、微電子技術(shù)等綜合運用,研究出了一套用于生豬規(guī)�；B(yǎng)殖的環(huán)境監(jiān)控系統(tǒng)。該系統(tǒng)通過傳感器采集各環(huán)境因子的實時值,將其送入到控制器STM32,經(jīng)過與預(yù)設(shè)值分析比對后,遵循事先制定的控制策略,發(fā)出控制信號,驅(qū)動相關(guān)的執(zhí)行設(shè)備,從而達(dá)到控制參數(shù)的目的,營造出一個舒適的豬舍環(huán)境。此外,這些值通過CAN總線上傳到辦公室端的主機(jī)中,方便管理人員通過人機(jī)交互界面實時查看這些量,并能根據(jù)需要隨時調(diào)整各參數(shù)限值,以適應(yīng)不同階段的豬對環(huán)境的要求。
[Abstract]:According to the requirements of pig breeding and the environmental characteristics of pig house, four environmental factors-temperature, humidity, ventilation and light, which affect the growth and development of pigs were summarized on the basis of a large number of Chinese and English literatures. At the same time, the historical development and present situation of pig house environmental control technology have a clear understanding. First of all, enterprises investigate the actual problems existing in pig farms and consult the needs of managers. At the same time, we can understand the growth curve of piglets and the most suitable growth environment of pigs at different stages from the staff. Then the overall idea of the system is put forward, and several feasible schemes are drawn up. After comparison, screening, the best scheme is selected. Finally, the hardware circuit design and software design (the development environment based on library function) is completed. Through the simulation test, the main controller can accurately measure the environment variables and realize the control of various output devices. In this paper, the modern control theory, sensor technology, micro-electronic technology and other comprehensive applications, a set of environmental monitoring system for large-scale pig breeding has been developed. The system collects the real-time value of each environmental factor through the sensor, sends it to the controller STM32, after comparing with the pre-set value analysis, follows the pre-formulated control strategy, sends out the control signal, and drives the related execution equipment. So as to achieve the purpose of controlling parameters and create a comfortable pigsty environment. In addition, these values are uploaded to the host computer in the office through CAN bus, which makes it convenient for managers to view these quantities in real time through the human-computer interface, and can adjust the parameter limits at any time according to the need to adapt to the environmental requirements of pigs at different stages.
