1 Introduction

As the core control component of disinfection cabinets, control boards determine product stability, functional realization and intelligence level. With the diversified market demand for disinfection cabinets (household embedded, commercial large-capacity, portable, etc.) and higher industrial requirements for efficiency and cost control, the traditional one-piece control board design is facing problems such as high R&D iteration cost, low production universality and difficult after-sales maintenance.

Modular design, a modern industrial design method featuring decomposition and recombination, realizes the standardized design of control board functional units and flexible assembly according to product requirements. Its application in disinfection cabinet control boards conforms to the development trend of kitchen electric control components toward standardization, serialization and modularization, and effectively promotes the optimization of the entire industrial chain from R&D and production to after-sales. This paper discusses the core connotation, design system and industrial application practice of modular control boards for disinfection cabinets.

2 Core Connotation and Design Principles of Modular Design

2.1 Core Connotation

Modular design decomposes the control board system into independent, standardized and interchangeable functional modules based on functional attributes, working principles and structural characteristics, on the premise of ensuring overall product performance. Each module has independent structure, function and unified interface standards, supporting independent R&D, production, testing and maintenance. The whole control board is assembled by multiple modules via a unified interface, and its functions can be flexibly adjusted by adding, reducing or replacing modules.

2.2 Basic Design Principles

Standardization and Universality: Unify module interface specifications, installation dimensions and electrical parameters to realize universal application across different control board models and standardized production/replacement.

Functional Independence and Compatibility: Each module has clear and independent functions without mutual interference, and good compatibility to support free combination for different control board configurations.

Reliability and Maintainability: Optimize module structural design to ensure stable operation in high-temperature and humid working environments of disinfection cabinets; the modular structure facilitates disassembly, quick fault location and module replacement in after-sales maintenance.

Cost Optimization and Scalability: Reduce R&D and production costs through mass production of standardized modules; reserve expansion interfaces to be compatible with new functional modules (e.g., intelligent connection, multi-mode disinfection) for subsequent function upgrading.

3 Module Division and Key Technical Points of Disinfection Cabinet Control Boards

3.1 Rational Module Division

According to the core functions of disinfection cabinet control boards, the system is divided into several core functional modules with clear boundaries:

Power Supply Module: Provides stable and graded power for all modules, with over-voltage, over-current and over-temperature protection functions.

Control Core Module: The "brain" of the control board, composed of MCU/PLC chips and peripheral circuits, responsible for signal processing, instruction issuing and overall operation control.

Input/Output Module: Includes key, touch and display sub-modules (input) and drive sub-modules for disinfection, heating and ventilation components (output).

Detection Module: Collects real-time data such as cabinet temperature, humidity, ozone concentration and door switch status for closed-loop control.

Communication Module: Realizes data transmission and remote control for intelligent disinfection cabinets, compatible with WIFI, Bluetooth and other communication protocols.

3.2 Key Technical Points

Unified Interface Design: Adopt standardized electrical and mechanical interfaces to ensure fast assembly and stable connection between modules, reducing compatibility problems.

Environmental Adaptation Design: Strengthen the anti-interference, moisture-proof and high-temperature resistance of modules to adapt to the harsh working environment inside disinfection cabinets.

Modular Programming: Adopt modular programming ideas to realize independent development and debugging of each module's program, improving R&D efficiency and reducing maintenance difficulty.

Integrated Testing Technology: Establish a dedicated modular testing system to realize independent testing of single modules and joint testing of the whole system, ensuring product quality.
