Embodiment Construction

[0043] The following is a detailed description of the embodiments of the present invention. This embodiment is carried out based on the technical solution of the present invention, and provides detailed implementation methods and specific operation processes to further explain the technical solution of the present invention.

[0044] The relationship between the various levels of the traditional financial self-service equipment system, such as figure 1 As shown, it includes: application program layer, standard SPAPI interface layer, XFS management layer, device SP service, and hardware module. Among them, the application layer realizes the business processes of financial self-service equipment through the combination of various modules; the XFS management layer refers to the management and control layer in the scheduling process of the management program, such as the handle, request ID, message distribution, and memory management, and is responsible for invoking the correspondi...

Abstract

The invention discloses a CEN / XFS-based concurrent calling method for a card reading composite module. The method comprises the steps of setting a composite SP service and N parallel sub-services between a composite module and an application program layer, and enabling the N sub-services to be in one-to-one correspondence with the N sub-modules of the composite module respectively; a state pollingmechanism and an instruction interruption mechanism are introduced into the N SP sub-services and the composite SP service; according to the state polling mechanism, a current card reading instruction is blocked in a medium state circulation detection process; only when the medium is detected, the current card reading instruction is directly sent to the composite SP service to be executed, so that the sequence of receiving multiple concurrent card reading instructions by the composite SP service is determined by the sequence of placing the medium by a user, and the concurrent execution problem supporting medium state detection is solved; and the instruction interruption mechanism is further used for solving the concurrent execution problem which does not support medium state detection, sothat the current card reading instruction sent by the application program layer does not influence the handling of the card associated service due to the fact that the medium is not put into the current card reading instruction.

Description

technical field [0001] The invention relates to the technical field of financial self-service equipment, in particular to a concurrent call method of a CEN / XFS-based card-reading composite module. Background technique [0002] WOSA (Windows Open System Architecture, Windows Open System Architecture) is a software architecture under the Windows operating system proposed by Microsoft Corporation. WOSA / XFS (Windows Open System Architecture / Extensions for Financial Services), also known as CEN / XFS protocol, is an extended financial service based on WOSA. It is a software architecture proposed by Microsoft for the global financial industry software. It is based on the WOSA software architecture On the basis, some corresponding revisions have been made for the global financial industry. [0003] The CEN / XFS protocol provides a set of standard and unified protocols for the technical field of financial self-service equipment. It is a general and open protocol and has been widely us...
