Description
Technical Field
[0001] This invention belongs to the field of medical technology, specifically a small electronic temperature card that integrates dust detection and adsorption functions. Background Technology
[0002] Against the backdrop of strict epidemic control measures for close contact, people are paying increasing attention to individualized and grid-based disinfection, purification, and epidemic prevention operations. Currently, common epidemic prevention measures include forehead thermometers, disinfectant solutions, and air purifiers. However, these existing epidemic prevention devices and equipment are mostly designed for single functions. Forehead thermometers can be used to measure temperature but cannot purify the air, and disinfectant solutions can only be used for local disinfection and cannot absorb dust around the human body. Furthermore, there is a risk of cross-infection when multiple people use them. In addition, in small, enclosed spaces such as homes, classrooms, offices, and workshops, the above-mentioned common epidemic prevention devices are often used by multiple people, are bulky and difficult to carry, and cannot be moved flexibly in space. Several companies have made improvements to the epidemic prevention devices, mainly in terms of electrical performance indicators, and some prototypes have been developed. However, they all have drawbacks such as large size, difficulty in carrying, limited functionality, and unfriendly interfaces. In grid-based space epidemic prevention, traditional single epidemic prevention devices and equipment still dominate.
[0003] Most existing epidemic prevention devices have limited functions and require multiple uses by multiple people, posing significant problems in addressing epidemic prevention in grid spaces such as homes, offices, and classrooms. Furthermore, some of these devices are large, bulky, and complex to operate, making them unsuitable for use by the elderly and children.
[0004] Therefore, the present invention provides a small electronic temperature card that integrates dust detection and adsorption functions. Summary of the Invention
[0005] To address the shortcomings of existing technologies and solve the problems of most epidemic prevention devices having limited functions, requiring multiple users and repeated use, and presenting significant challenges in epidemic prevention in grid spaces such as homes, offices, and classrooms, as well as the issues that some epidemic prevention devices are large, bulky, and complex to operate, making them unsuitable for the elderly and children, this invention proposes a small electronic temperature card that integrates dust detection and adsorption functions.
[0006] The technical solution adopted by the present invention to solve its technical problem is as follows: A small electronic temperature card integrating dust detection and adsorption functions, comprising: a power module, a main control chip, a membrane keypad, a display screen, a vent, a power switch, and a housing. The power module and the main control chip are installed inside the housing. The power switch is installed on the top of the housing. The display screen is installed on the side of the housing. A vent is opened in the middle of the housing. The membrane keypad is installed on the bottom of the housing.
[0007] The main control chip includes a main controller module, which is based on the Arduino system and is used to process raw data information obtained from the dust detection module and the temperature detection module, and then transmit the processed data to the human-machine interaction module, the temperature detection module and the buzzer alarm module.
[0008] The power module consists of a 9V button battery, a 9V to 5V voltage conversion circuit, and a 9V to 3.3V voltage conversion circuit, which can reduce the 9V voltage to 5V and 3.3V respectively.
[0009] The buzzer alarm module is an electromagnetic passive buzzer, mainly used for alarms when the ambient dust content exceeds the standard or the temperature exceeds the set threshold.
[0010] The dust detection module is powered by a 5V power supply and has a detection accuracy of up to 1 mg / m³. 3 ;
[0011] The dust adsorption module is achieved by combining a small fan and a negative ion generator.
[0012] The temperature detection module uses a non-contact thermopile temperature measurement module, which can measure human body temperature at close range and set temperature thresholds, and works with a buzzer module to sound an alarm.
[0013] The human-computer interaction module uses a 0.96-inch monochrome OLED (organic electro-laser display) screen and five buttons. The buttons are thin-film buttons evenly arranged in the top, bottom, left, right and center, and the buttons adopt a rounded rectangular design.
[0014] Preferably, the human-computer interaction module is connected to the buttons via signal lines, the human-computer interaction module is connected to the OLED (organic electro-laser display) screen via signal lines, the ventilation holes are located directly opposite the dust adsorption module, and the power switch is connected to the power module via wires.
[0015] Preferably, the power module has an input voltage of 6.5V-12V and can still achieve stable voltage output of 5V and 3.3V. The 5V power supply port of the power module is connected to the dust detection module and the dust adsorption module, and the 3.3V power supply port is connected to the human-machine interaction module.
[0016] Preferably, in the buzzer alarm module, the base of the NPN transistor is connected to the I / O port of the main controller module via a 1K ohm resistor. When the main controller module controls the port to output a high level, the NPN transistor is turned on; when the output is low, the NPN transistor is turned off, thereby controlling the operation of the buzzer.
[0017] Preferably, the dust detection module is a negative ion generator control circuit. The gate of the NMOS transistor is connected to the I / O of the main controller. When the main controller outputs a high level, the NMOS transistor is turned on, and when it outputs a low level, the NMOS transistor is turned off, thereby controlling the opening and closing of the negative ion generator.
[0018] Preferably, the dust adsorption module uses a small fan to promote airflow to the negative ion generator. The air intake fan is located directly above the negative ion generator, and the negative ion generator's power-on circuit uses an N-channel MOSFET as an electronic switch.
[0019] Preferably, the temperature detection module is controlled by the main controller via IIC communication. In the circuit design, the interface needs to be externally connected to a pull-up resistor of about 10K ohms before being directly connected to the main controller module for communication.
[0020] Preferably, the human-machine interface module has a 0.96-inch monochrome OLED (organic electro-laser display) screen, and the I / O ports of the main controller module are directly connected. CS is the chip select terminal, RST is the hardware reset port, D / C is the data / command selection terminal, and D0 (the main controller D6) and D1 (the main controller D5) are the SCK (serial clock line) and MOSI (master output / slave input port or serial data port) of the SPI interface, respectively. The main controller controls the display content of the screen through SPI communication. After entering the first-level menu, the human-machine interface module can switch between mode selection and settings by pressing the up / down keys. When entering the second-level menu, pressing the up / down keys returns to the main menu, and pressing the left / right keys switches the function mode. After entering the second-level menu, pressing the middle key enters the corresponding next-level menu, and pressing the middle key again returns to the previous-level menu. After entering the temperature measurement details page, pressing the up key enters the temperature recording interface, and pressing the down key again returns to the temperature measurement interface.

[0039] The main control chip includes a main controller module, which is based on the Arduino system and is used to process the raw data information obtained from the dust detection module and the temperature detection module, and then transmit the processed data to the human-machine interaction module, the temperature detection module and the buzzer alarm module.
[0040] The power module consists of a 9V button battery, a 9V to 5V voltage conversion circuit, and a 9V to 3.3V voltage conversion circuit, which can reduce the 9V voltage to 5V and 3.3V. The power module can output stable 5V and 3.3V even with an input voltage of 6.5V-12V. The 5V power supply port of the power module is connected to the dust detection module and the dust adsorption module, and the 3.3V power supply port is connected to the human-machine interaction module.

In the buzzer alarm module, the base of the NPN transistor is connected to the I / O port of the main controller module through a 1K ohm resistor. When the main controller module controls the port to output a high level, the NPN transistor is turned on; when the output is low, the NPN transistor is turned off, thereby controlling the operation of the buzzer.
[0042] The dust detection module is powered by a 5V power supply and has a detection accuracy of up to 1mg / m³. 3 The dust detection module is a negative ion generator control circuit. The gate of the NMOS transistor is connected to the I / O of the main controller. When the main controller outputs a high level, the NMOS transistor is turned on, and when it outputs a low level, the NMOS transistor is turned off, thereby controlling the opening and closing of the negative ion generator.
[0043] The dust adsorption module uses a small fan to promote airflow to the negative ion generator. The air intake fan is located directly above the negative ion generator. The negative ion generator's opening circuit uses an N-channel MOSFET as an electronic switch.

In the circuit design, the interface needs to be connected to an external pull-up resistor of about 10K ohms before it is directly connected to the main controller module for communication.
[0045] The human-computer interaction module uses a 0.96-inch monochrome OLED (Organic Electro-Laser Display) screen and five buttons. The buttons are thin-film buttons evenly arranged in all directions (up, down, left, right, center), and have rounded rectangular shapes. The human-computer interaction module is connected to the buttons via signal cables, and the human-computer interaction module is also connected to the OLED (Organic Electro-Laser Display) screen via signal cables. Ventilation holes are located directly opposite the dust adsorption module. The power switch is connected to the power module via a wire. The human-computer interaction module, the 0.96-inch monochrome OLED (Organic Electro-Laser Display) screen, and the main controller module's I / O ports are directly connected. CS is the chip select pin, RST is the hardware reset port, D / C is the data / command selection pin, and D0 (the main controller D...) is the... 6) D1 (the main controller D5) are the SCK (serial clock line) and MOSI (master output / slave input port or serial data port) of the SPI interface, respectively. The main controller controls the display content of the screen through SPI communication. After entering the first-level menu, the human-machine interaction module can switch between mode selection and settings by pressing the up / down keys. When entering the second-level menu, press the up / down keys to return to the main menu, and press the left / right keys to switch function modes. After entering the second-level menu, press the middle key to enter the corresponding next-level menu, and press the middle key again to return to the previous-level menu. After entering the temperature measurement details page, press the up key to enter the temperature recording interface, and press the down key again to return to the temperature measurement interface.
[0046] Operating steps of the temperature measuring card: Turn on the power switch to start the power-on process, then configure the timer to initialize the OLED screen. If the initialization fails, the warning light will flash. After successful initialization, initialize GP2Y014AUOF, MLX906148CC, and the dust adsorption button. After the function initialization is completed, enter the menu interface.
[0047] After entering the menu interface, you can select the dust detection mode, dust adsorption mode, and temperature recording interface respectively.
[0048] You can determine whether the dust exceeds the standard through the dust detection details page. If the dust exceeds the standard, an alarm will be issued and the dust adsorption mode will be activated to adsorb and treat the dust.
[0049] The dust adsorption mode can also be activated separately to adsorb and treat dust.
[0050] When recording temperature, measure and record the current temperature, and check if the recorded temperature is greater than 9. If it is greater than 9, clear the record. If the recorded temperature is not greater than 9, return to the re-detection interface and re-detect.
[0051] When operating the dust detection mode, dust adsorption mode, and temperature recording mode, menu operations are used, allowing users to confirm, select, and cancel.
