This paper proposes a redundant network communication structure for the patient integrated circuit(IC)card payment system in a hospital information system(HIS),compares it with the network structure of normal hospital IC card system,and calculates the reliabilities of the related communications like the RS485communication and the Ethernet communication.The new structure can efectively promote the reliability of the hospital operation and ensure the payment collection when the Ethernet network is broken.The system is applied to a local hospital and the cost-performance rate is satisfactory during the application. 相似文献

五峰山长江大桥北锚碇沉井基础长100.7m、宽72.1m、高56m,沉井平面尺寸大,下沉深度深,为目前世界规模最大沉井。沉井下沉施工为本工程的关键工序,也是施工风险最大的工序,本项目在不排水下沉过程中,首次引进水下三维声呐扫测技术,将水面以下的沉井井壁、刃脚状态通过软件显示在图像上,实现了沉井下沉过程可视化,为沉井顺利下沉提供了有力的技术保障,并为后续沉井及围堰施工提供良好的借鉴。 相似文献
