Software development platform for embedded industrial control instrument

Abstract

The invention relates to a software development platform for an embedded industrial control instrument. The software development platform comprises a hardware driving layer, a system platform scheduling layer, a product application layer and a product customization layer, wherein the hardware driving layer and the system platform scheduling layer form a platform core layer; the product application layer and the product customization layer form a product layer; the hardware driving layer comprises driving codes of correlated hardware modules of the industrial control instrument; the system platform scheduling layer comprises codes of basic scheduling and managing functions of an embedded operation system and codes of basic processing functions of the industrial control instrument; the product application layer comprises related common codes of varied products of the industrial control instrument; the product customization layer comprises various customization codes for different specific products; and codes of the hardware driving layer and the system platform scheduling layer are compiled and packaged to form an LIB library file for the codes of the product application layer and the product customization layer to call. The software development platform benefits standardization, normalization and collaboration of product development; and according to the software development platform, the development efficiency is increased, the utilization rate of development resources is increased, and the development and maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of embedded industrial control instrument software development, in particular to a software development platform suitable for embedded industrial control instruments developed based on ARM CORTEX-M3 / M4 processors. Background technique [0002] Domestic industrial control digital display instruments have developed from the late 1980s to the present, from imitating foreign instruments to independent innovation, and successfully replacing imported instruments. The development of service and product quality puts forward higher requirements for the specialization and customization of instrument design. [0003] In the past, as long as industrial digital display instruments can realize signal acquisition, LED display, relay control, analog output, and communication functions, plus the support of PID control algorithm and flow algorithm, they can basically meet the requirements of users. With the advancement of te...

AI Technical Summary

Problems solved by technology

At present, the latest CORTEX-M3 / M4 series ARM chip is used as the main processor in the development of slightly complicated instruments. Its cost performance has surpassed that of the 51 series single-chip microcomputer. single chip microcomputer

Therefore, in the development of products with more complex functions in the future, the use of this series of CPU will further improve the function and cost performance of the product, but it will also increase the complexity of new product design.

[0005] The software development of the early industrial control digital display instrument was mainly completed by several backbone technicians in the company during the whole development process independently. The design source code, technology and experience were mainly accumulated in several backbones. difficult for people to intervene

In addition, the chips used by each person are different, and the development tools and compilation environment are also different. It is difficult for even the technical backbone to intervene in the product development designed by others, and the personal successful experience cannot be copied and promoted by others.

Once there is a loss of personnel, subsequent product development and maintenance will consume huge resources and losses

Therefore, with the continuous increase in the complexity of product design, this development model has been difficult to meet the requirements. Instrument development companies urgently need a new development model that can quickly, high-quality and efficiently meet customer needs. If multi-person collaborative development and management can be realized, Will greatly shorten the product development cycle
