Abstract
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 RS485 communication and the Ethernet communication. The new structure can effectively 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.
