Description

Software development method, device, equipment and medium based on component model

Technical Field

The present disclosure relates to the field of software development technologies, and more particularly, to a software development method, apparatus, device, and medium based on a component model.

Background

Industrial control systems are a general term for various control systems and related instruments, devices, field networks in industrial process control, and such systems have been of great importance in national industrial development. In recent years, scientific technologies in various fields including control technologies, computer technologies, electronic technologies, and mechanical manufacturing technologies have been developed rapidly.

Currently, the development of industrial control systems is gradually moving towards a multi-supplier, multi-team collaborative, multi-module integrated model, and the functions thereof are increasingly complex and complex. More and more new technologies and more efficient communication protocols are integrated therein, which is a huge challenge for traditional industrial control system development teams and control system field engineers responsible for system integration. On the other hand, existing industrial control systems are becoming more open, and application software at various levels in the market is often provided and integrated by multiple suppliers. The software provided by these manufacturers often depends on a specific operating environment or a specific hardware controller, and lacks certain portability and flexibility. Software modules between different vendors also lack a unified deployment and interaction solution in terms of interoperability.

Software development methods and related technologies have been a research field of great interest for software systems, and among them, component-based software development has been a promising development method in the field of software engineering. By developing a system as a combination of multiple subcomponents rather than as a complex whole, the component-based development method aims to improve the reusability of software to greatly accelerate the development speed and save the development cost. Under the support of a proper component model, application software can be rapidly constructed by multiplexing existing components, and each modularized component also has a low coupling characteristic so as to support a multi-team cooperation development mode. In addition, the software system constructed based on the components has better expandability and usability so as to face complex software running environment and continuously upgrade and update software requirements, and each software functional module has the flexibility of plug and play. At present, more and more component-based development methods and component models are applied to software development in various fields, including embedded systems and specific industrial fields.

The application of component technology to various practical scenes is one of the trends of the current computer including the embedded field, and the introduction of a component-based development method and a software architecture into the industrial control field can effectively cope with the development trends of reusability, openness and comprehensiveness of the contemporary industrial control system, and can improve the flexibility, compatibility and expandability of the system.

as shown in fig. 4:

In the software development apparatus based on the component model according to the present disclosure, the component construction module 201 is sequentially connected to the component encapsulation module 202, the transmission module 203, and the software development module 204.

Example three:

the present disclosure can also provide a computer storage medium having stored thereon a computer program for implementing the steps of the above-described component model-based software development method when executed by a processor.

The computer storage medium of the present disclosure may be implemented with a semiconductor memory, a magnetic core memory, a magnetic drum memory, or a magnetic disk memory.

Semiconductor memories are mainly used as semiconductor memory elements of computers, and there are two types, mos and bipolar memory elements. Mos devices have high integration, simple process, but slow speed. The bipolar element has the advantages of complex process, high power consumption, low integration level and high speed. NMos and CMos were introduced to make Mos memory the dominant memory in semiconductor memory. NMos is fast, e.g. 45ns for 1K bit sram from intel. The CMos power consumption is low, and the access time of the 4K-bit CMos static memory is 300ns. The semiconductor memories described above are all Random Access Memories (RAMs), i.e. read and write new contents randomly during operation. And a semiconductor Read Only Memory (ROM), which can be read out randomly but not written in during operation, is used to store solidified programs and data. The ROM is divided into non-rewritable fuse type ROM-PROM and rewritable EPROM.

The magnetic core memory has the characteristics of low cost and high reliability, and has more than 20 years of practical use experience. Magnetic core memories were widely used as main memories before the mid 70's. The storage capacity can reach more than 10 bits, and the access time is 300ns at the fastest speed. The international typical magnetic core memory capacity is 4 MS-8 MB, and the access cycle is 1.0-1.5 mus. After semiconductor memory is rapidly developed to replace magnetic core memory as a main memory location, magnetic core memory can still be applied as a large-capacity expansion memory.

Drum memory, an external memory for magnetic recording. Because of its fast information access speed and stable and reliable operation, although its capacity is smaller and is gradually replaced by disk memory, it is still used as external memory for real-time process control computers and medium and large computers. In order to meet the needs of small and micro computers, subminiature magnetic drums have emerged, which are small, lightweight, highly reliable, and convenient to use.

Magnetic disk memory, an external memory for magnetic recording. It combines the advantages of drum and tape storage, i.e. its storage capacity is larger than that of drum, its access speed is faster than that of tape storage, and it can be stored off-line, so that the magnetic disk is widely used as large-capacity external storage in various computer systems. Magnetic disks are generally classified into two main categories, hard disks and floppy disk memories.

Hard disk memories are of a wide variety. The structure is divided into a replaceable type and a fixed type. The replaceable disk is replaceable and the fixed disk is fixed. The replaceable and fixed magnetic disks have both multi-disk combinations and single-chip structures, and are divided into fixed head types and movable head types. The fixed head type magnetic disk has a small capacity, a low recording density, a high access speed, and a high cost. The movable head type magnetic disk has a high recording density (up to 1000 to 6250 bits/inch) and thus a large capacity, but has a low access speed compared with a fixed head magnetic disk. The storage capacity of a magnetic disk product can reach several hundred megabytes with a bit density of 6 bits per inch and a track density of 475 tracks per inch. The disk set of the multiple replaceable disk memory can be replaced, so that the disk set has large off-body capacity, large capacity and high speed, can store large-capacity information data, and is widely applied to an online information retrieval system and a database management system.
