Track traffic automatic fare collection system reader-writer middleware

Abstract

The invention discloses track traffic automatic fare collection system reader-writer middleware. According to the thought of developing the reader-writer middleware in a layered mode, an independent dynamic function layer of hardware and an operating system is sealed between a hardware layer and an application layer to shield differences among interfaces of different hardware, and compatibility of different bottom devices of application program of an existing reader-writer is achieved. Specific call of functions is achieved through conducting dynamic loading on a dynamic function library in the whole software system, and the function of equipment management is completed. By means of the track traffic automatic fare collection system reader-writer middleware, the reader-writer middleware is adopted to provide universal services between platforms such as the hardware and the operating system and the application, the redundancy of data is reduced, different business requirements of an upper-level system for the data are met through complex event processing, and the defect that when the terminal reader-writer changes every time, upgrading and development of the hardware and the operating system are needed for another time is overcome.

Description

technical field [0001] The invention relates to a middleware for a reader-writer of a rail transit automatic fare collection system, which belongs to the radio frequency reading and writing technology. Background technique [0002] Ticketing processing in urban rail transit system is a very complicated process. Reader equipment and ticket cards change frequently, and face various changes such as ticket media updates, ticket structure changes, ticket business rules changes, and ticket application scope changes. The reader / writer is a component that directly interacts with the passenger ticket card to complete the reading and writing process of the ticket card. Readers include hardware and software. Hardware devices are often manufactured by different manufacturers, and the implementation methods are opaque. There are usually differences in interface standards, even if the hardware produced by the same manufacturer has been upgraded and replaced. These problems make it very c...

Problems solved by technology

These problems make it cumbersome to develop applications with the same or similar functions on different underlying hardware devices

Every time the same application software is implemented on different hardware platforms, it needs to be redeveloped. Undoubtedly, this is an unwise duplication of labor for developers and operators.
