Universal peripheral driving interface

Abstract

The invention discloses a universal peripheral driving interface, to achieve wider universality of the universal peripheral driving interface and provide a good technical support for the development of a financial front-end system. The universal peripheral driving interface is characterized by comprising two hierarchies, one is a universal public driving interface, and the other is a universal device driving interface; the universal device refers to a financial periphery device; the two hierarchies are provided to a business system to be scheduled, however the difference between financial periphery devices of different models is shielded for the business system, and the business system and the periphery driving are decoupled.

Description

technical field [0001] The invention relates to a peripheral drive control technology of a financial front-end system, in particular to a general peripheral drive interface. Background technique [0002] The mainstream types of peripherals in the financial industry include passbook printers, journal printers, password keyboards, magnetic stripe readers, IC card readers, fingerprint readers and many other devices; each device has different drivers and instructions due to different manufacturers and models. Generally are not the same. For example, there are more than ten mainstream PIN pad manufacturers in China at present, and the PIN pad products of each manufacturer can be divided into encryption or non-encryption type, mechanical keyboard type or touch keyboard type, single function type or integrated function type, etc. model. For the same customer, due to historical reasons, the purchase time of the above-mentioned financial peripherals is different, resulting in the e...

Problems solved by technology

For the same customer, due to historical reasons, the purchase time of the above-mentioned financial peripherals is different, resulting in the existence of multiple brands and models of the same type of equipment, and the corresponding operating system must be able to support the above-mentioned complicated equipment at the same time

Moreover, in view of the above situation, software integrators will generally face the following problems when developing related systems: 1) During system development, peripheral drivers have nothing to do with business functions, but they cannot separate system business functions from peripheral drivers well , the tightly coupled mode leads to a large addition or modification of the system code every time a new device is added or replaced; 2) During system development, each different type of peripheral needs to compile a corresponding driver code , the development workload is heavy, the development cycle is long, and the system stability is not good; 3) When the system is running, when the device fails, flexible device model switching cannot be performed, and maintenance is inconvenient

4) During system development and operation, the technical level of development and operation and maintenance technicians is required to be high, which increases the overall cost of the system
