Implementation method of phone payment terminal software platform

Abstract

The invention provides an implementation method of a phone payment terminal software platform. The method comprises the following steps of: setting a bottom layer, a second layer, a third layer and a top layer on the software platform of the products of the same model from bottom to top, setting a guide and upgrade program module, a power management module, a memory management module and an interruption foreground-background management module on the bottom layer, setting an event management module, a device management module, a hardware configuration module and a universal drive logic on the second layer, and setting a test program module on the top layer, wherein the constituent parts at the lower layers support the constituent parts of the upper layer, the constituent parts of the same layer can be dependent on each other. The software platform further comprises a database module and a financial service utility function library, which do not strictly belong to the second layer and the top layer. The phone payment terminal software platform based on the SunPlus 16-bit processor environment can effectively reduce the coupling degree of the upper application software and the hardware, simplify the upper software development details and accelerate migration on the hardware products of different models.

Description

【Technical field】 [0001] The invention relates to a realization method of a telephone payment terminal software platform based on Sunplus 16-bit processor environment. 【Background technique】 [0002] Telephone payment is an emerging financial payment mode. Due to the characteristics of flexible customization of business processes, rich business functions, low terminal deployment costs, and low access thresholds, the current development of telephone payment services is very rapid. The telephone payment terminal is an embedded product, which is used to collect transaction information and cooperate with the telephone payment platform to complete the telephone payment business. [0003] Common telephone payment terminals may have multiple functional devices. Generally speaking, a telephone payment terminal has a liquid crystal display, a set of keys, a magnetic stripe card reader, a set of smart card readers, a printer, a set of handles for telephone functions and other equipm...

AI Technical Summary

Problems solved by technology

The disadvantages of this software environment are: the software code volume of the entire project is large and complex, and the development of its upper-layer application requires upper-layer business knowledge and lower-layer driver knowledge to successfully solve various problems in the development; the coupling degree of the entire software and hardware is very high. High, once the product is migrated to a new model, both the upper-layer application and the lower-layer driver software need to be modified a lot; the lack of scheduling and management mechanism makes the software process prone to various abnormalities, which in turn affects the performance of the whole machine software; Lack of separation mechanism between the upper-level software and the lower-level software, so that when the software of any level or module needs to be modified, it will affect the recompilation of the overall software project, and the maintenance cost is relatively high

This increases the hardware cost of the phone payment terminal
