【摘要】：糧食是每一個(gè)國(guó)家發(fā)展的經(jīng)濟(jì)基礎(chǔ),關(guān)系著國(guó)家民生的發(fā)展大計(jì),并且已經(jīng)上升到特殊戰(zhàn)略儲(chǔ)備物資的地位,甚至可以影響國(guó)家的安全以及社會(huì)的穩(wěn)定。糧食的數(shù)量、質(zhì)量以及安全與國(guó)家的經(jīng)濟(jì)是否能夠健康發(fā)展息息相關(guān),因此如何利用科學(xué)的辦法來存儲(chǔ)糧食成了重中之重。我國(guó)糧倉(cāng)的建設(shè)起步比較晚,設(shè)備比較落后,因此在糧食存儲(chǔ)過程中損耗比較大。除了糧食存儲(chǔ)倉(cāng)庫(kù)落后之外,我國(guó)檢測(cè)糧倉(cāng)內(nèi)的溫度以及濕度的方法比較落后,需要人工檢測(cè)并且檢測(cè)的參數(shù)比較單一,這樣就出現(xiàn)了數(shù)據(jù)量不多、無法實(shí)時(shí)監(jiān)測(cè)數(shù)據(jù)等一系列問題。正因?yàn)樵诩Z倉(cāng)的檢測(cè)過程中出現(xiàn)了各種各樣的問題,所以我們?cè)诒M量改善糧食存儲(chǔ)環(huán)境的同時(shí)提出了基于無線網(wǎng)絡(luò)的溫濕水一體化糧情監(jiān)測(cè)系統(tǒng)。該系統(tǒng)主要是利用傳感器采集糧倉(cāng)內(nèi)糧食的溫度、濕度以及谷物的水分,糧倉(cāng)內(nèi)的數(shù)據(jù)采集器通過M-BUS通訊以及RS-485接口獲取傳感器的數(shù)據(jù)并將這些數(shù)據(jù)通過WiFi模塊上傳到整個(gè)糧庫(kù)的數(shù)據(jù)集中器中,數(shù)據(jù)集中器再通過GPRS模塊將所有糧倉(cāng)的數(shù)據(jù)上傳并保存到服務(wù)器。在服務(wù)器上部署了通訊軟件,用來實(shí)時(shí)監(jiān)聽數(shù)據(jù)集中器中是否有數(shù)據(jù)傳送,如果有數(shù)據(jù)傳送,則把數(shù)據(jù)保存到服務(wù)器上的數(shù)據(jù)庫(kù)中,為用戶通過Internet訪問糧情監(jiān)測(cè)系統(tǒng)的界面提供數(shù)據(jù)支持。文章首先介紹了該課題研究的背景、意義、國(guó)內(nèi)外現(xiàn)狀以及未來的發(fā)展趨勢(shì);其次介紹了糧情監(jiān)測(cè)系統(tǒng)的相關(guān)技術(shù)、開發(fā)語(yǔ)言、硬件以及軟件的整體設(shè)計(jì)方案;然后重點(diǎn)介紹了數(shù)據(jù)采集器以及溫濕度傳感器的設(shè)計(jì)與實(shí)現(xiàn),具體主要包括GPRS模塊、WiFi模塊、M-BUS通訊、RS-485通訊、為各個(gè)模塊供電的電源電路設(shè)計(jì)以及為硬件提供頂層支持的軟件設(shè)計(jì),并給出了相關(guān)的硬件設(shè)計(jì)電路圖、相關(guān)軟件的流程框圖、關(guān)鍵代碼以及通訊協(xié)議;最后介紹了部署到服務(wù)器上的三部分內(nèi)容,分別是上位機(jī)與數(shù)據(jù)集中器之間的通訊軟件、數(shù)據(jù)庫(kù)設(shè)計(jì)以及糧情監(jiān)測(cè)系統(tǒng)的訪問界面。本課題設(shè)計(jì)的基于無線網(wǎng)絡(luò)的溫濕水一體化糧情監(jiān)測(cè)系統(tǒng),該系統(tǒng)能夠獲取溫度、濕度以及谷物水分的原始數(shù)據(jù),并且可以通過網(wǎng)絡(luò)訪問糧情監(jiān)測(cè)系統(tǒng)的界面,能夠查看最新采集到的數(shù)據(jù)、查詢?nèi)魏螘r(shí)間段的歷史數(shù)據(jù)并且可以獲取該采集點(diǎn)縱向上的溫度、濕度以及水分的曲線。
[Abstract]:Grain is the economic base of the development of every country, which is related to the development of the national livelihood, and has risen to the status of special strategic reserve material, which can even affect the security of the country and the stability of the society. The quantity, quality and safety of grain are closely related to the healthy development of the country's economy, so how to use scientific methods to store grain has become a top priority. The construction of granary in our country starts late and the equipment is backward, so the wastage of grain storage process is large. In addition to the backwardness of grain storage warehouses, the methods of detecting temperature and humidity in grain warehouses in China are relatively backward, and the parameters that need manual detection and detection are relatively single. Thus, there is a small amount of data. Unable to monitor data in real time and a series of problems. Because there are various problems in the process of granary detection, we put forward an integrated monitoring system of temperature, humidity and water based on wireless network while improving the storage environment of grain as much as possible. The system mainly uses sensors to collect the temperature, humidity and moisture of grain in the granary. The data collector in the granary acquires the data of the sensor through the M-BUS communication and the RS-485 interface and uploads the data to the data concentrator of the whole grain depot through the WiFi module. The data concentrator uploads and saves all granary data to the server through the GPRS module. The communication software is deployed on the server to monitor whether there is data transfer in the data concentrator in real time and, if there is, to save the data to the database on the server. It provides data support for users to access the interface of grain condition monitoring system through Internet. This paper first introduces the background, significance, current situation and future development trend of the research, and then introduces the related technology, development language, hardware and software of the whole design of the grain situation monitoring system. Then the design and implementation of data collector and temperature and humidity sensor are introduced, including GPRS module, M-BUS communication module and RS-485 communication, power supply circuit design for each module and software design to provide top-level support for hardware. The related circuit diagram of hardware design, flow chart of related software, key code and communication protocol are given. Finally, three parts of communication software are introduced, which are the communication software between the upper computer and the data concentrator. Database design and access interface of grain condition monitoring system. Based on the wireless network, this system can obtain the original data of temperature, humidity and grain moisture, and access the interface of the grain condition monitoring system through the network. Can view the latest collected data, query the historical data of any time period, and get the temperature, humidity and moisture curves of the sampling point longitudinally.
