Research And Application Of Smart Card System In Digital Sanatorium

With the medical health system reform, in the survival and development, the sanatoriumis facing new opportunities and challenges. In order to adapt the needs of health development,the sanatorium is actively promoting information construction and striving to create digitalsanatorium. In the process of constructing digital sanatorium, and achieving a medicalcheck-up process information and the administrative office automation, but on the entirebusiness lack of unified information construction planning, the various business relativeindependence, data is not to be Shared, and led to the generation of information island, unableto realize the overall business process optimization.In this paper, taking the HuaDong sanitarium smart card system based on, exploring theintegration of business process in the digital sanatorium. The sanitarium business process isdifferent from the hospital to treat mainly, but also different from the entertainment andleisure holiday resort, it mainly provides the recuperation rehabilitation, health examination,holiday, meeting and other services. Therefore, the sanatorium smart card system was notsuccessful case to follow. In domestic hospital, it is being implemented to card and bar codeas the carrier of the smart card system. But the identification card safety performance is nothigh, just as the carrier of patient identity authentication. All funds, are in the backenddatabase for converting, no established in identification card capital account division, realizethe identification card and database double verification. And, the smart card system propertieslimited, mainly concentrated in the diagnosis and treatment and be in hospital, No cover tocatering, access control, shopping and other consumer link, these responded the smart cardsystem application and design flaws. This paper discusses the sanitarium smart card system requirement analysis, systemdesign, system realization process, in general, have the following innovation points:1) Following the he design concept of information sharing and centralized control.Byestablishing key management system for the unified identity authentication, in a card performvarious functions on different intelligent management and application. Through to the overalldesign and planning of heterogeneous subsystem, building unified data platform,comprehensive and integrated business process, eliminate information island.To make fulluse of the existing network conditions, avoiding the laid special network, through theinstallation of serial Protocol converters, make some equipment which supported RS-485communications to support TCP/IP (Transmission Control Protocol/Internet Protocol)Protocol, the whole system is based on TCP/IP Protocol, unified network platform. Finallyrealize the system 'one card, one library, one net' stable operation, application range covershealth check-up, entertainment health care, food service management, shopping, attendancemanagement and access management.2) Capital account Settings flexible, and in identification card and data in the table arerespectively set up different capital account. To meet the needs of different consumption,change the traditional of the smart card system set for single account to account Settings, suchas setting general account and special account. The general account funds can be used for allsale point, the special account funds can only be in particular sale point. In data table, set upthe only account type Numbers for each account, used to distinguish the account, brushcalorie of consumption, according to sale point attribute set, the system will analysis theamount of account which can be called automatically, reduce the manual intervention. At thesame time, in the EEPROM (Electrically Erasable Programmable Read-only Memory) ofidentification card, classified different account funds storage division, and synchronized thecapital account in database.3) Improved he safety of the identification card and capital account, realized the dualauthentication between identification card and database, in the process of credit card, not onlythrough checking card state in the table, verify the usability of identification card, but also bycomparing identification card account information and the database account information,verify the validity of the identification card. In addition, the capital of carry forward, in thedatabase and identify card synchronously, and establish the data rolled back mechanisms toprevent identification card account funds and fund accounts to be inconsistent.To sum up, this article bases on the personalized needs of digital sanitarium, integrateand optimize business process, realized the'one card in hand, including traffic'. Finally, executive pressure test respectively in Transaction test scene and mixed transactions scene byLoadRunner test software, find out the defects of the system, and put forward the performanceoptimization scheme. The test results show that the system can support200virtual concurrentusers, and achieve the expected design goal.
