Technical Field

[0001] The present invention relates to the technical field of LED sterilization and dehumidification, and in particular to a deep ultraviolet LED sterilization and dehumidification device based on a single chip microcomputer. Background Art

[0002] Regarding single-chip microcomputer technology, significant progress has been made recently, but existing equipment still has some shortcomings, such as performance limitations, poor integration and flexibility, and high development difficulty. Most existing equipment and instruments are outdated technologies from a few years ago.

[0003] There are many types of disinfection and sterilization technologies available, many of which require specific equipment such as high-temperature ovens and steam sterilizers. This leaves much to be desired in the field of electronic information technology. For traditional single-chip microcomputers, there is no complete and mature solution for integrating sterilization and dehumidification functions.

[0004] Current education in the field of electronic information technology is increasingly embracing the Internet of Things and informatization, but existing equipment and technologies are underperforming in this area, resulting in a significant technological gap. Existing products focus on either traditional single-chip microcontrollers and embedded development or high-end artificial intelligence and big data applications. However, there are no comprehensive products that can simultaneously address the needs of basic single-chip microcontroller development, multifunctional designs, and integrated sterilization and dehumidification equipment.

[0005] The existing host computer designs in the field of electronic information technology mostly use high-level languages ​​such as C++, JAVA, TCL, Python, and Assembly. These languages ​​are traditional programming languages, and generally have a long entry period. The designed host computer software cannot be used across operating system platforms. At the same time, there are no corresponding courses for learning such high-level languages ​​in ordinary electronic information technology professional fields. Therefore, the learning cycle and difficulty of these languages ​​are uncertain, and they have failed to achieve better development in the field of electronic information. Summary of the Invention

[0006] Using artificial intelligence theory and single-chip microcomputer technology, sensor technology, embedded theory and language programming basics as theoretical guidance, we designed a sample of a smart wardrobe with sterilization and dehumidification. Using combined module management and mechanical manufacturing technology, we developed a sterilization and dehumidification wardrobe that can solve the problems of moisture and mold in existing wardrobes, effectively improving the dehumidification and sterilization efficiency.

[0007] The technical solution adopted by the present invention to solve the above-mentioned problems is: a single-chip microcomputer-based sterilization and dehumidification device, characterized by: a material with ultraviolet light-reflecting properties attached to the inner wall; the device comprises a main control unit, a data acquisition unit connected to the main control unit, a display unit, and an input / output unit. The main control unit includes an STM32 single-chip microcomputer; the data acquisition unit includes a digital temperature and humidity sensor module; the display unit includes an LED module and a liquid crystal display module; and the input / output unit includes an optocoupler isolation relay module, an independent button module, a gold-power aluminum-shell resistor module, and a fan module.

[0008] Furthermore, the inner wall is attached with materials having the property of reflecting ultraviolet light, such as aluminum foil, double-conducting copper foil, steel foil, etc.

[0009] Furthermore, the STM32 single-chip microcomputer module adopts the control chip of STM32F103C8.

[0010] Furthermore, the acquisition unit module adopts a digital temperature and humidity sensor with model number GY-SHT30-D.

[0011] Furthermore, the display unit module uses 6 deep ultraviolet LED lamps in parallel; and uses a display screen, the model of which is an IIC1602 liquid crystal display screen.

[0012] Furthermore, the deep ultraviolet LED lamp has an output wavelength of 275nm, a radiation power of 5-8mW, and a light-emitting angle of 60°.

[0013] Furthermore, the input and output unit optocoupler isolation relay module adopts a 1-way, 3.3V, DC relay; the golden power aluminum shell resistor module adopts a resistance value of 25 ohms; and the fan module adopts a 5cm (thickness 1cm) 12V silent fan.

[0014] The beneficial effects of the single-chip microcomputer-based deep ultraviolet LED sterilization and dehumidification device of the present invention include: enabling simultaneous single-chip microcomputer development, integrating multifunctional designs such as sterilization and dehumidification, hardware debugging and testing, software download, and other operations, meeting the needs of daily teaching and scientific research, simplifying traditional development processes, and streamlining development tools. During use, users only need to perform simple configuration and wiring to conduct corresponding experiments. Future improvements are expected to make the device easier to operate, such as improving sensor technology, enhancing communication capabilities, and improving the user interface.

[0015] In addition, the embodiments of the present invention achieve: first, completing learning and experimental projects that traditionally require 5-6 sets of equipment on one set of equipment; second, completing the integrated development experiments of knowledge in multiple fields, such as the development of single-chip microcomputers and multi-functional devices, reducing the demand for additional hardware, simplifying the design and reducing costs; third, the single-chip microcomputer can realize flexible control logic and operation modes through programming to adapt to different disinfection and sterilization needs.

[0025] This embodiment will be further described in detail below with reference to the accompanying drawings and specific implementations.

[0026] like Figure 1As shown, this embodiment provides a single-chip microcomputer-based deep ultraviolet LED sterilization and dehumidification device, the inner wall of which is attached with a material with ultraviolet light reflective properties. The device includes a main control unit, a data acquisition unit connected to the main control unit, a display unit, and an input / output unit. The main control unit includes an STM32 single-chip microcomputer; the data acquisition unit includes a digital temperature and humidity sensor module; the display unit includes an LED module and a liquid crystal display module; the input / output unit includes an optocoupler isolation relay module, an independent button module, a gold power aluminum shell resistor module, and a fan module.

[0027] like Figure 2 As shown, the deep ultraviolet LED modules are installed in a sealed container with steel foil in a preset arrangement. When the irradiation time reaches 30 seconds, the sterilization rate is as high as over 90%, and the disinfection and sterilization efficiency is high.

[0028] like Figure 3 As shown, the STM32 core board module adopts the STM32 series microcontroller development board (MCU). In this embodiment, the control chip U5 of model STM32F103C8 is selected; the STM control chip U5 is connected to a synchronous buck regulator DC / DC, a display controller module and a connector, etc.

[0029] like Figure 4 As shown in the figure, the acquisition unit module uses the GY-SHT30-D digital temperature and humidity sensor. Like the display, it uses the I2C communication protocol and only requires two data lines (SDA and SCL) to connect to the development board. It has the characteristics of high precision, low power consumption and high reliability.

[0030] like Figure 5 As shown, the display unit includes a deep ultraviolet LED module and a liquid crystal display module.

[0031] The display unit is a deep ultraviolet LED, wherein the output wavelength is 275nm, the radiation power is 5-8mW, and the light-emitting angle is 60°.

[0032] like Figure 7 As shown, the display unit uses an IIC (LCD) 1602 liquid crystal display. The IIC interface only requires two data lines (SDA and SCL) to communicate with the microcontroller and has good anti-interference ability. Due to the small number of pins required, the required cables and connectors can be reduced in complex circuits, thereby saving hardware costs and simplifying circuit design.

[0033] like Figure 8 As shown, the input and output unit includes an optocoupler isolation relay module, an independent button module, a gold power aluminum shell resistor module, and a fan module.

[0034] The single-chip microcomputer-based deep ultraviolet LED sterilization and dehumidification device can simultaneously carry out a series of operations such as single-chip microcomputer development, integration of sterilization, dehumidification and other multifunctional designs, hardware debugging and testing, and software download.

[0035] In this embodiment, to enable the same equipment to meet diverse learning and development needs, the hardware design features rich resources, standardized interfaces, compatible and switchable controllers, flexible installation, and ease of use. This is achieved through the selection of hardware and the design of the overall equipment framework. Furthermore, the equipment's wiring structure is rational, allowing users to freely connect and combine various modules. In terms of hardware selection, mainstream hardware components are used, with commonly used interfaces that meet international standards reserved to ensure that user learning is aligned with actual application. The following are the names and model parameters of the key hardware devices on the device.

[0036] In this embodiment, the single-chip microcomputer-based deep ultraviolet LED sterilization and dehumidification device allows users to complete one-stop learning of professional knowledge on a set of equipment, from entry to advanced, to advanced applications, and finally to system design.

[0037] To provide a one-stop learning experience for users, the integrated device comes with comprehensive teaching resources that break down the device hardware into its components. The integrated device also comes with at least one textbook: the STM32 Microcontroller Design and Development Guide.

[0038] This textbook covers many practical training case experiments. All experiments can be found in the corresponding teaching chapters in the corresponding textbooks, allowing users to combine theory with practice and gain a thorough understanding.

[0039] In this embodiment, a stable and reliable software firmware program and hardware circuit are designed to simplify and repackage complex logic algorithms, presenting users with a simple development process.
