基于智能手机的鸡病辅助诊治系统开发与应用

针对鸡常见群发疾病桌面计算机辅助诊断系统使用不便、普及率低、时效性差等局限性，该研究采用新一代智能手机作为开发平台，以.Net 2005为开发语言，以SQL Server 2005 CE为数据库，对常见鸡群发疾病的病因性知识与诊断知识进行了数字化整理，建立了基于可信度的产生式规则推理机制等，研制了适合于农村中小规模养鸡场和基层兽医使用的智能手机鸡病辅助诊治系统。结果表明：系统构建了面向对象的鸡病诊断知识库，在推理分析环节引入可信度，可通过主要症状、疑似症状或多症状组合3种可选方法，对70多种主要鸡病进行辅助诊断，并提供相应的治疗或其他处置措施。系统应用结果表明，该系统辅助诊断准确率达88.3%，且使用方便、操作简单、易于普及。随着TD-SCDMA与Internet的融合与应用，通过不断更新该系统运行所支持的知识库，逐步提高诊断准确率，使得该系统在中国广大农村具有广阔的应用前景。

Development and application of assistant system for diagnosing chicken diseases based on smart mobile phones

Currently, the chicken disease diagnosis system based on desk-top computers has displayed timely inconvenience and poor coverage in operation. To meet the demands of medium or small-scale poultry farms and grass-root veterinarians, a chicken disease diagnosis and health management system based on windows mobile 5.0 working under Net 2005 and SQL Sever 2005 CE was developed. Object-oriented knowledge bases were established and credibility factors (CF) were also introduced in the inference mechanism. The system could diagnose more than 70 common chicken diseases and provide suggestions on appropriate veterinary drugs and treatment with 3 options: obvious symptoms, suspect diseases and multi-symptom combinations. The system performance test showed that diagnostic accuracy of the assistant system based on smart mobile phones was to 88.3%. The windows mobile system was convenient to operate and easy to put into use. With the integration of TD-SCMA and Internet, the system can definitely foresee a wide application in the countryside because it can be kept up-dated in time and improve its accuracy in diagnosis.
