The Design And Implementation Of Heterogeneous Visitor Management System Based On SOA

Traditional access control management and channel management tend to focusonly on private areas of intelligent building safety management, in order to put anend to a variety of security vulnerabilities and to improve the level of security, butalso the need to strengthen management of public areas and access to a private area.Management in the private area there is often a lot of heterogeneous hardware andsoftware platforms and a variety of access control, channel safety control systemequipment, these systems from different vendors and different times, using differenttechniques, different development environments, different implementations methodsand data structures, and they tend to have the identity of the independent media andauthentication module management with individual user permissions and role data.This article first summarizes the temporary visitor management,service-oriented architecture, enterprise service bus and Web Service concepts andtechniques, and then analyze the status of temporary visitor management andproblems of intelligent building, established the business model of visitormanagement andinterface services-based integration approach based bus business.Then on visitor management system based on service-oriented architecture designand implementation, including system management module, visitor managementmodule, channel management module interface service module. Visitor card, visitorcard as an identity medium customize heterogeneous systems through the EnterpriseService Bus ESB adapter, interface services to achieve a seamless connection withthe JSE Access Control System, G3access control system and channel system.The context of actual product development projects, on the basis of in-depthanalysis of the existing temporary visitor management and channel access controlmanagement, a service-oriented architecture SOA (Service Oriented Architecture),through the Enterprise Service Bus ESB (Enterpriseintegrated Service Bus) toachieve heterogeneous systems interconnection model. The model first defines aservice contract, that is the message class, including the class of the request andresponse message; followed by heterogeneous systems adapter, external call of thecoarse-grained form of interface services; asynchronously send through the ServiceBus request message, the interface according to the message type to select the rightheterogeneous systems adapter, carry out their respective business processing andresponse message to return by bus to the processing results. The model can bedeveloped with the different periods of the system does not change the existingsystem investments to achieve interoperability, to meet the integration needs of heterogeneous systems, visitor management systems with heterogeneous dataexchange and device control.Finally, through rigorous functional testing and performance testing to verifythe feasibility of heterogeneous systems integration based on SOA, visitormanagement system has better scalability, compatibility and stability.
