Abstract: Design patterns are the essence of object-oriented design. This paper analyzes the basic characteristics of the Adapter pattern. In the design process of embedded human-machine interface configuration software, the hierarchical structure of the graphical elements of the configuration software is analyzed. The Adapter pattern is applied to the design, enhancing the reusability, flexibility, and maintainability of the code, and improving development efficiency. Keywords: Design pattern; Adapter pattern; Configuration software 1. Introduction Embedded human-machine interfaces play an increasingly important role in industrial control and management. Among them, configuration software is the core for completing editing and control. The idea of ​​configuration is to decompose the industrial control system into many entities, and complete the construction of the entire system by configuring the attributes and relationships of each entity. This idea is very suitable for object-oriented design methods. Design patterns are the essence of object-oriented design, describing the design methods and structures for solving specific problems. This paper analyzes the graphical elements of configuration software and applies the Adapter pattern to the design to improve the flexibility and development efficiency of the software. 2. Embedded Human-Machine Interface Configuration Software 2.1 Embedded Human-Machine Interface A human-machine interface (HMI) is a way for humans to interact with machines. Configuration software refers to specialized software for data acquisition and process control. It's a software tool that allows users to quickly build their own HMIs. Traditional HMI configuration software involves editing the configuration screen and implementing monitoring functions on a PC. With the development of embedded technology, embedded HMIs can more effectively perform monitoring functions. However, directly writing industrial monitoring applications into an embedded system results in poor flexibility and scalability. To address this issue, this paper aims to research and design a configuration software for embedded HMIs. This software allows editing the monitoring configuration interface on a host computer (PC) and generating a configuration information configuration file, which is then downloaded to the slave device (embedded device) via serial port. During slave device operation, the file is parsed, and monitoring and control operations on the PLC are performed. (See Figure 1.)
