【摘要】：隨著農(nóng)業(yè)結(jié)構(gòu)調(diào)整和相關(guān)國家政策的扶持,農(nóng)林牧漁發(fā)展迅速,特別是畜牧養(yǎng)殖業(yè)占到整體產(chǎn)值的1/3,根據(jù)國家統(tǒng)計局的數(shù)據(jù)顯示,畜牧業(yè)每年都維持在平均值30%左右,在增加了養(yǎng)殖戶的經(jīng)濟收入的同時,也促進了國家經(jīng)濟的流通,增加了GDP。雖然規(guī)�；B(yǎng)殖已經(jīng)逐漸替代傳統(tǒng)粗放型養(yǎng)殖方式,但是這種趨勢依然改變不了養(yǎng)殖過程中的粗放管理方式,通風、排污、取暖等設(shè)施不完備,甚至沒有,導致牲畜生長環(huán)境惡劣,容易引起動物疾病、死亡,畜牧產(chǎn)品質(zhì)量不過關(guān)等問題。本文根據(jù)畜牧養(yǎng)殖場舍間布局特點,利用傳感器技術(shù)、ZigBee技術(shù)、Linux技術(shù)等相關(guān)先進的物聯(lián)網(wǎng)嵌入式技術(shù),設(shè)計了一種針對畜牧養(yǎng)殖場的環(huán)境信息遠程監(jiān)測系統(tǒng)。主要完成任務(wù)如下:1)在通過分析國內(nèi)外關(guān)于環(huán)境監(jiān)測設(shè)計資料和國內(nèi)畜牧養(yǎng)殖場管理模式的基礎(chǔ)上,提出了畜牧養(yǎng)殖場環(huán)境信息實時監(jiān)測的設(shè)計方案。方案內(nèi)容擬定采用ZigBee技術(shù)搭建ZigBee無線傳感網(wǎng)絡(luò)采集現(xiàn)場環(huán)境數(shù)據(jù)通過ARM中心平臺進行處理,再通過GPRS模塊發(fā)送數(shù)據(jù)包到遠程監(jiān)測中心。2)在系統(tǒng)低成本設(shè)計的要求下,對系統(tǒng)各模塊進行具體選型。選用DHT11作為溫濕度信息采集模塊;選用CC2530芯片作為ZigBee無線傳感網(wǎng)絡(luò)組織模塊,搭建無線網(wǎng)絡(luò),負責傳輸環(huán)境數(shù)據(jù)到協(xié)調(diào)器;選用ARM11作為嵌入式硬件開發(fā)平臺,負責處理環(huán)境數(shù)據(jù)的接收、顯示、存儲和轉(zhuǎn)發(fā)等相關(guān)操作;選用GPRS DTU作為遠程信息傳輸方式,負責發(fā)送數(shù)據(jù)到遠程監(jiān)測中心。3)編寫ZigBee協(xié)議棧應(yīng)用層用戶程序,主要實現(xiàn)功能為:自動組織ZigBee網(wǎng)絡(luò),采集環(huán)境數(shù)據(jù),發(fā)送環(huán)境數(shù)據(jù)。編寫嵌入式平臺運行程序:嵌入式系統(tǒng)搭建包括Bootloader、Linux內(nèi)核、Linux文件系統(tǒng)的構(gòu)建和移植,在Qt環(huán)境下GUI的運行程序,GPRS DTU發(fā)送程序等。4)采用MFC類設(shè)計遠程監(jiān)測中心監(jiān)測界面及其功能實現(xiàn)。主要任務(wù)可以使得監(jiān)測中心能通過套接字技術(shù)與GPRS DTU進行數(shù)據(jù)交流,接收ARM11平臺經(jīng)由GPRS和Internet網(wǎng)絡(luò)傳輸過來的環(huán)境數(shù)據(jù),實現(xiàn)對現(xiàn)場畜牧養(yǎng)殖場環(huán)境的遠程監(jiān)測。整個監(jiān)測系統(tǒng)在設(shè)計完成后,經(jīng)過調(diào)試和組裝,放在現(xiàn)場環(huán)境進行了穩(wěn)定性和丟包率的測試。其中ZigBee端丟包率平均為0.13%,GPRS端丟包率平均為0.0%,測試結(jié)果表明,系統(tǒng)性能穩(wěn)定,工作狀態(tài)良好,可以正常采集畜牧養(yǎng)殖場環(huán)境信息數(shù)據(jù),能實現(xiàn)動態(tài)顯示、實時存儲、定時轉(zhuǎn)發(fā)等功能,滿足低成本下對畜牧養(yǎng)殖場環(huán)境信息監(jiān)測的需求。
[Abstract]:With the readjustment of the agricultural structure and the support of relevant state policies, agriculture, forestry, animal husbandry and fishery have developed rapidly, especially the livestock farming industry, which accounts for a third of the total output value. According to the data from the National Bureau of Statistics, animal husbandry is maintained at an average of about 30 percent annually. In addition to increasing farmers' economic income, it also promotes the circulation of the national economy and increases the GDPs. Although large-scale aquaculture has gradually replaced the traditional extensive farming methods, this trend still does not change the extensive management in the breeding process, ventilation, sewage, heating and other facilities are not complete, or even do not have. It is easy to cause animal disease, death, poor quality of livestock products and so on. According to the layout characteristics of livestock farms, a remote monitoring system of environmental information for livestock farms is designed by using the sensor technology, such as ZigBee technology, Linux technology and other advanced embedded technology of the Internet of things. The main tasks are as follows: (1) based on the analysis of the environmental monitoring design data at home and abroad and the management mode of domestic livestock farms, the design scheme of real-time monitoring of environmental information of livestock farms is put forward. ZigBee technology is used to set up ZigBee wireless sensor network to collect field environmental data through arm central platform, and then send data packet to remote monitoring center through GPRS module under the requirement of low cost design of the system. The specific selection of each module of the system is carried out. Choose DHT11 as temperature and humidity information collection module, CC2530 chip as ZigBee wireless sensor network organization module, build wireless network, responsible for transmitting environmental data to the coordinator; select ARM11 as embedded hardware development platform, select CC2530 chip as ZigBee wireless sensor network organization module, select ARM11 as embedded hardware development platform, Take charge of receiving, displaying, storing and forwarding environmental data, select GPRS DTU as remote information transmission mode, send data to remote monitoring center. 3) compile application layer user program of ZigBee protocol stack. The main functions are: organizing ZigBee network automatically, collecting environment data and sending environment data. Write the running program of the embedded platform: the embedded system construction includes the construction and transplantation of the Linux file system, the Linux kernel of Bootloadern. In QT environment, the running program of GUI, GPRS DTU sending program, etc. 4) is designed by MFC class to realize the monitoring interface of remote monitoring center and its function. The main task can make the monitoring center exchange data with GPRS DTU through socket technology, receive the environmental data transmitted by ARM11 platform via GPRS and Internet network, and realize the remote monitoring of the environment of the field livestock farm. After the design of the whole monitoring system is completed, the stability and packet loss rate are tested in the field environment after debugging and assembling. The average packet loss rate of ZigBee end is 0.13. The average packet loss rate of GPRS terminal is 0.00.The test results show that the system has stable performance and good working condition. It can collect environmental information data of livestock farm normally and realize dynamic display and real-time storage. The function of timing forwarding can meet the need of environmental information monitoring of livestock farms at low cost.
