【摘要】：伴随着计算机技术和通信技术的不断发展,医疗信息化也得到了众多医疗机构的高度重视。移动查房/护理系统的应用使医疗工作从原先的办公室桌面移到了病人床旁,缩短了医护人员的诊疗时间,提高了工作效率和病人满意度,已经成为医疗信息化发展的一个重要方向。无线局域网是移动查房/护理系统应用的基础,其性能的好坏直接影响到临床医护人员的工作效率。因此,网络的规划、设计与部署成为移动查房/护理系统实施的重要部分。为保证移动查房/护理系统能够稳定、快速、安全地运行,论文对我院网络进行了规划设计和部署,具体工作内容包括以下方面:1.根据医院业务需求,结合已有网络基础,制定了网络建设总体规划方案,提出了合理的组网架构和拓扑结构;2.有线网络部分,结合实际需求,在充分对比分析的基础上,对核心交换机、接入交换机、无线AP等网络设备进行了选型和部署;3.针对医院空间环境的特殊性,考虑终端移动性、无线覆盖、频点配置、吞吐量等因素,对无线AP的安装位置进行合理规划,达到无线局域网性能优化的目的;为便于网络管理和维护,制定了统一的无线网络SSID和设备命名规则,对无线网络VLAN/IP地址进行了合理的规划设计;对核心交换机、无线控制器、接入交换机等无线网络设备进行合理配置,实现了与原有有线局域网的互联互通;4.对无线局域网的信号强度、覆盖范围、网络延时、信道切换等进行性能测试与分析,并通过移动查房/护理系统的程序应用来验证无线局域网的性能。论文提出的网络架构和实施方案实现了病区的无缝覆盖,多方位、多角度的性能测试表明:网络性能稳定、数据吞吐量高、信道切换平稳,达到设计要求,对移动查房/护理系统的应用提供了有力的支撑。
[Abstract]:With the development of computer technology and communication technology, medical informatization has been attached great importance to by many medical institutions. The use of mobile rounds / nursing systems has moved medical work from the original office table to the patient's bed, shortened the time spent in the diagnosis and treatment of health care personnel, improved work efficiency and patient satisfaction, Has become an important direction of medical information development. Wireless local area network (WLAN) is the basis of mobile ward / nursing system, and its performance directly affects the efficiency of clinical medical staff. Therefore, network planning, design and deployment become an important part of mobile rounds / nursing system implementation. In order to ensure that the mobile ward / nursing system can run stably, quickly and safely, this paper plans and designs the network of our hospital, including the following aspects: 1. According to the requirement of hospital business and combined with the existing network foundation, the overall plan of network construction is established, and the reasonable network structure and topological structure are put forward. In the part of wired network, combined with the actual demand, the core switch, access switch, wireless AP and other network equipments are selected and deployed on the basis of full comparison and analysis. In view of the particularity of hospital space environment, considering the factors of terminal mobility, wireless coverage, frequency point configuration, throughput and so on, the installation location of wireless AP is reasonably planned to achieve the purpose of optimizing the performance of wireless local area network (WLAN). In order to facilitate the network management and maintenance, the unified wireless network SSID and device naming rules are formulated, and the wireless network VLAN/IP address is reasonably planned and designed. Access switch and other wireless network equipment reasonable configuration to achieve the original wired LAN interconnection and interworking. 4. The signal strength, coverage range, network delay and channel switching of WLAN are tested and analyzed, and the performance of WLAN is verified by the program of mobile rounds / nursing system. The proposed network architecture and implementation scheme achieve seamless coverage, multi-orientation and multi-angle performance test. The results show that the network performance is stable, the data throughput is high, the channel switching is stable, and the design requirements are met. It provides strong support for the application of mobile rounds / nursing system.
