基于物联网技术的面向情境感知的医院智能诊疗体系方法研究

There are some problems in the present medical system, like long queuing due to no intelligent control of waiting patients, insufficient advisable treatment plan in patients' need as well as lack of fixed location of special patients. In this project，based on the technology of internet of things and the characteristic of context information in the diagnosis and treatment of hospital, the construction of systematic method for the context-aware system of intelligent diagnosis and treatment is studied ,fully considering the context constraints of diagnosis rules on time, location, environment ,hospital resources and patient demands on medical expenses, visiting time, physician credibility and so on. The specific research contents include four aspects as follows: First, on the basis of the modeling of context information and its constraints in the diagnosis and treatment of hospital, extending the service objects and service contents based on the web services description language of WSDL, the service description model of intelligent diagnosis and treatment is constructed from the three aspects of service interaction, service function and service status; And then form the four aspects of service matching, service selection, service composition and service mapping, the dynamic service combination strategy in intelligent diagnosis and treatment is proposed and also the specific algorithm is constructed; Next, based on the network service access control model of RBAC, the service access control model in intelligent diagnosis and treatment is constructed and the access control mechanism oriented service in intelligent diagnosis and treatment is also formulated; At last, the prototype application platform of intelligent diagnosis and treatment is built and the application scheme is put forward. The project aims to provide systematic method for the construction of context-aware system of intelligent diagnosis and treatment based on the technology of internet of things ，providing scientific basis for its application and implementation.

目前，医院诊疗存在着无法为等待患者提供智能调度以减少排队现象、无法根据患者需求为其推荐就诊方案、无法对特殊病人跟踪定位等弊端。基于物联网技术，立足医院诊疗的情境特点，充分考虑诊疗对时间、位置、环境、资源的限定规则和病患对费用、时间、医生信誉度的实际需求等情境约束条件，研究构建面向情境感知的医院智能诊疗体系方法，具体如下：在对诊疗情境信息及其约束条件建模的基础上，基于网络服务描述语言WSDL，扩充其服务对象和服务内容，从服务交互、服务功能和服务状态三方面构建智能诊疗服务描述模型；从服务匹配、服务选择、服务组合、服务映射四方面提出智能诊疗服务动态组合策略，构建具体算法；基于网络服务访问控制模型RBAC，构建智能诊疗服务访问控制模型，形成智能诊疗服务访问控制机制；搭建智能诊疗原型平台，提出应用方案。旨在为基于物联网技术的面向情境感知的医院智能诊疗体系构建提供系统方法，为其应用与实施提供科学依据。
