【摘要】：目前我國禽類養(yǎng)殖發(fā)展速度很快,但同時也存在各種因素的干擾,如傳染病的流行、新病不斷增加、頻現(xiàn)變異、耐藥性增強(qiáng)、營養(yǎng)代謝病等給養(yǎng)雞業(yè)帶來巨大危害。這些因素給雞病臨床診斷和疾病防控帶來了巨大的挑戰(zhàn)。鑒于現(xiàn)階段我國中小型養(yǎng)雞場面臨的基層獸醫(yī)人員缺乏及臨床診斷技術(shù)落后的現(xiàn)狀,開發(fā)雞病診斷和防控系統(tǒng)是非常必要的。本研究通過獸醫(yī)技術(shù)與計算機(jī)信息技術(shù)的最新研究成果開發(fā)研制“雞病診斷與防控信息系統(tǒng)”,進(jìn)而改進(jìn)我國養(yǎng)雞業(yè)的現(xiàn)狀,提高疾病臨床診斷的準(zhǔn)確率及制定合理的防控措施。雞病診斷與防控信息系統(tǒng)采用B/S/D三層結(jié)構(gòu)模式進(jìn)行設(shè)計,應(yīng)用Microsoft Visual Studio.NET 2008、Visual C#開發(fā)語言與SQL Server 2008數(shù)據(jù)庫等實驗工具進(jìn)行構(gòu)建。雞病診斷與防控信息系統(tǒng)的知識獲取采用人工獲取知識的方式,通過對雞病領(lǐng)域?qū)＜抑R及經(jīng)驗的歸納總結(jié)、匯總、整理并存儲在系統(tǒng)的知識庫中,形成完整的數(shù)據(jù)庫。系統(tǒng)共存儲了85種雞常見疾病癥狀信息及疾病防控方案,建立34個數(shù)據(jù)庫、3140條規(guī)則,收集疾病圖片518個、視頻39個。本系統(tǒng)采用面向?qū)ο蟮闹R表示方法以對象-屬性-值三元組知識表示方法結(jié)合產(chǎn)生式規(guī)則知識表示法表示雞疾病知識,易于知識庫的修改、維護(hù)及更新,同時使知識結(jié)構(gòu)更加清晰。系統(tǒng)運用不確定規(guī)則推理與案例推理相結(jié)合的推理機(jī)制,充分結(jié)合兩種推理理論的優(yōu)點,進(jìn)而提高系統(tǒng)疾病診斷的準(zhǔn)確率。本系統(tǒng)最終實現(xiàn)的功能如下:(1)本項研究成功開發(fā)研制出“雞病診斷與防控信息系統(tǒng)”,該系統(tǒng)能夠?qū)εR床常見85種雞病進(jìn)行診斷和防控。(2)雞病診斷與防控信息系統(tǒng)利用后臺數(shù)據(jù)庫中疾病癥狀信息、圖片及系統(tǒng)推理機(jī)制三位一體結(jié)合模式實現(xiàn)疾病診斷過程。用戶根據(jù)實際發(fā)生病例癥狀與系統(tǒng)中疾病信息進(jìn)行匹配同時可以參照疾病癥狀圖片,通過系統(tǒng)的推理機(jī)制推理出疾病診斷結(jié)果供用戶參考。(3)雞病診斷與防控信息系統(tǒng)提供疾病防治方案及免疫方案供用戶應(yīng)用,用戶參考系統(tǒng)提供的防治方案和免疫方案并結(jié)合本場雞群的實際情況制定合理的防控措施。(4)雞病診斷與防控信息系統(tǒng)提供了知識查詢模塊,提供疾病知識查詢、疫苗知識查詢、藥物知識查詢、圖片與視頻知識查詢、實驗室檢查知識查詢,實現(xiàn)了知識的查詢功能。為用戶提供知識學(xué)習(xí)平臺。
[Abstract]:At present, poultry breeding in China is developing rapidly, but there are also various factors, such as the epidemic of infectious diseases, the increasing of new diseases, the frequent variation, the increase of drug resistance, and the nutritional metabolic diseases, which bring great harm to the chicken industry. These factors bring great challenges to clinical diagnosis and disease prevention and control of chicken disease. In view of the lack of primary veterinary staff and the backward clinical diagnosis technology in small and medium-sized chicken farms in China at present, it is very necessary to develop the diagnosis and control system of chicken disease. Through the latest research results of veterinary technology and computer information technology, this study developed the "chicken disease diagnosis and control information system", and then improved the current situation of chicken industry in China. To improve the accuracy of clinical diagnosis of disease and to formulate reasonable prevention and control measures. The information system of chicken disease diagnosis and control was designed with B/S/D three-layer structure mode, and was constructed with Microsoft Visual Studio.NET 2008 Visual C # development language and SQL Server 2008 database. The knowledge acquisition of chicken disease diagnosis and control information system adopts the way of artificial acquisition of knowledge, through the induction and summary of expert knowledge and experience in chicken disease field, it is arranged and stored in the knowledge base of the system to form a complete database. The system has stored 85 kinds of chicken common disease symptom information and disease prevention and control plan, established 34 databases, 3140 rules, collected 518 disease pictures, 39 video. In this system, object-oriented knowledge representation method is used to represent chicken disease knowledge by object-attribute-value triple knowledge representation method combined with production rule knowledge representation, which is easy to modify, maintain and update the knowledge base. At the same time, make the knowledge structure clearer. The system combines uncertain rule reasoning with case-based reasoning and combines the advantages of the two reasoning theories to improve the accuracy of disease diagnosis. The functions of the system are as follows: (1) the information system of chicken disease diagnosis and control has been developed successfully in this study. The system can diagnose and control 85 kinds of chicken diseases in clinic. (2) the information system of chicken disease diagnosis and control realizes the disease diagnosis process by using the disease symptom information, picture and system reasoning mechanism in the backstage database. The user matches the disease information in the system according to the actual case symptom and can refer to the picture of the disease symptom. The result of disease diagnosis is inferred by the system reasoning mechanism for user's reference. (3) the information system of chicken disease diagnosis and prevention and control provides the disease prevention and control scheme and the immune scheme for the user to apply. The prevention and cure scheme and immunization scheme provided by the user reference system and combined with the actual situation of chicken flocks in this field were used to formulate reasonable prevention and control measures. (4) the chicken disease diagnosis and control information system provided the knowledge query module and provided the disease knowledge inquiry. Vaccine knowledge query, drug knowledge query, picture and video knowledge query, laboratory examination knowledge query, knowledge query function is realized. Provide knowledge learning platform for users.
