Description

Technical Field

[0001] This invention relates to the field of environmental monitoring, and more particularly to an intelligent bionic butterfly device for environmental monitoring. Background Technology

[0002] Modern people spend a significant amount of time indoors, and indoor air quality directly impacts health. Decoration materials and furniture may release harmful substances such as formaldehyde and benzene. Long-term exposure can lead to respiratory diseases, allergies, and even cancer. At the same time, indoor temperature, humidity, and ventilation also affect comfort and quality of life. Monitoring can help identify potential problems in a timely manner, take measures to improve them, ensure indoor environmental safety, and provide people with healthy and comfortable living and working spaces. This is an important means of safeguarding public health.

[0003] Enclosed spaces (such as homes, offices, and classrooms) are prone to accumulating high concentrations of pollutants such as CO2, PM2.5, and VOCs. Long-term exposure can lead to respiratory diseases, decreased attention, and pathological "building syndrome." Environmental data is often presented in the form of professional charts, which are difficult for the public to understand intuitively, resulting in delays in environmental protection actions. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an intelligent bionic butterfly device for environmental monitoring.

[0005] In a first aspect, the present invention provides an intelligent biomimetic butterfly device for environmental monitoring, comprising a base, and further comprising:

[0006] The butterfly wings are mounted on top of the base via support rods;

[0007] A drive assembly, installed on the top of the support rod, is used to drive the flapping of the butterfly wings to control the flapping frequency of the butterfly wings;

[0008] The control module, installed inside the base, is used to monitor air quality indicators in real time and to build a dynamic monitoring network.

[0009] A warning component, installed on the butterfly wing, is used to map the pollution level by changing the color of light.

[0010] When the control module detects that the indoor environmental quality is substandard, the control module activates the drive component. The drive component drives the dual-wing mechanism to complete one adaptive vibration frequency movement per minute. The movement posture reflects changes in environmental quality. When pollution intensifies, the vibration frequency increases, thus intuitively reflecting changes in indoor environmental quality. Through ecological data visualization design, such as mapping pollution levels through butterfly movement frequency / color changes, the threshold for data understanding is reduced.

[0011] Preferably, the driving component includes:

[0012] A support frame is fixed to the top of the support rod;

[0013] An electric actuator is fixed to one end of the support frame via a mounting tube;

[0014] The movable rod is fixed to the telescopic rod end of the electric push rod;

[0015] Two rotating sleeves are rotatably installed inside the support frame and are both sleeved on the outside of the moving rod. The two rotating sleeves are respectively fixedly connected to the two wings of the butterfly wing.

[0016] Two guide slots are respectively opened inside the two rotating sleeves and are arranged symmetrically;

[0017] Both sliding contacts are fixed to the side wall of the moving rod and are slidably connected to the two guide slots respectively;

[0018] After the electric push rod is started, it drives the moving rod to move via the telescopic rod. The moving rod drives the sliding contact to move. The sliding contact slides inside the guide groove, thereby driving the rotating sleeve to rotate under the action of the guide groove. This rotating sleeve drives the butterfly wings to fan, thus driving the butterfly wings to adjust different fanning frequencies under different environmental pollution conditions.

[0019] Preferably, the warning component includes:

[0020] Multiple LED lights are fixed to the butterfly wing, and the LED lights are used to provide warnings by changing various light colors;

[0021] The LED lights installed on the butterfly wings can change color according to the level of different pollutants. This color change serves as a warning when pollutants exceed the standard. Furthermore, the combination of LED light changes and the flapping of the butterfly wings increases the user's attention and improves the likelihood of the user noticing the warning. This enhances the warning effect without causing panic like a sudden sound warning.

[0022] Preferably, the butterfly wing body adopts a recycled aluminum alloy frame and a 3D printed castor oil-based resin skeleton, and the surface is covered with a PHBV / PLA biodegradable flexible membrane. The main structure is made of recyclable materials, and the components support biodegradation or closed-loop recycling after disposal.

[0023] Preferably, the control module includes:

[0024] A carbon dioxide monitoring module is used to monitor the carbon dioxide content in the environment.

[0025] The VOCs monitoring module is used to monitor the VOCs gas content in the environment.

[0026] The PM monitoring module is used to monitor PM levels in the environment.

[0027] Temperature monitoring module, used to monitor ambient temperature;

[0028] Humidity monitoring module, used to monitor ambient humidity;

[0029] OLED display screen for real-time display of test data;

[0030] The WIFI module is used to connect and network the various modules.

[0031] The controller, when the value detected by the carbon dioxide sensor, VOCs monitoring sensor, or PM sensor exceeds a threshold, controls the warning component to issue an alert and activates the linked air purifier to purify the ambient air; when the value detected by the temperature sensor exceeds a temperature threshold, the controller controls the warning component to issue an alert and activates the linked air conditioner to adjust the ambient temperature; when the value detected by the humidity sensor exceeds a threshold, the controller controls the warning component to issue an alert and activates the linked humidifier or dehumidifier to regulate the ambient humidity.

[0032] Preferably, the control module further includes:

[0033] An input module is used to input the monitoring thresholds of each monitoring module;

[0034] The outdoor monitoring module is used to monitor the levels of PM and VOCs in the outdoor environment.

[0035] The controller is used to acquire the monitoring value from the carbon dioxide monitoring module. When the monitoring value exceeds the threshold, the controller is used to control the outdoor monitoring module to start so as to monitor the outdoor environmental values.

[0036] The controller is also used to acquire outdoor monitoring values ​​from the outdoor monitoring module. When the outdoor monitoring values ​​are all maintained within the normal range, it is used to control the smart window to open and send window opening information to the user terminal.

[0037] When the outdoor monitoring value exceeds the threshold, the control unit controls the activation of the linked camera to monitor indoor personnel activities. If no one is detected indoors, no additional control is performed. If personnel activities are detected indoors, the control unit controls the activation of the linked fresh air system to filter and replace the indoor air environment.

[0038] Preferably, the control module further includes:

[0039] The time control module is used to adjust the start-up time of the fresh air system according to the arrival time input by the input module;

[0040] The time control module is used to obtain the final value A of carbon dioxide concentration control through the input module, obtain the current carbon dioxide concentration value A through the carbon dioxide monitoring module, and obtain the change value A of carbon dioxide concentration adjusted by the fresh air system within a specified time t through the input module.

[0041] The time control module is used to calculate the remaining time T based on the return time, and control the carbon dioxide monitoring module to monitor the carbon dioxide concentration at specified time intervals t to obtain the change value A of indoor carbon dioxide concentration at each specified time interval t. When the change value A of carbon dioxide concentration is less than, the carbon dioxide concentration adjustment time T is calculated according to T = AA / |A|. When the calculated remaining time T is greater than or equal to the carbon dioxide concentration adjustment time T, no additional control is performed.

[0042] When the remaining time T is less than the carbon dioxide concentration adjustment time T, the time control module calculates the total operating time T of the fresh air system according to T = A - A + |A|T / A - |A|, and calculates the fresh air system operating time according to the return time and the total operating time T of the fresh air system. The controller controls the fresh air system to start on a timed basis according to the fresh air system operating time of the time control module.

[0043] Preferably, the control module further includes:

[0044] When the carbon dioxide concentration change value A is equal to , the time control module calculates the total operating time T of the fresh air system according to T = AA / A, and calculates the fresh air system operating time according to the time of returning home and the total operating time T of the fresh air system. The controller controls the fresh air system to start on a timed basis according to the fresh air system operating time of the time control module.

[0045] Preferably, the control module further includes:

[0046] When the carbon dioxide concentration change value A is greater than a certain value, the controller immediately controls the activation of the linked fresh air system and sends a warning message to the user to warn the user that there is an abnormality in the indoor combustion equipment.

[0047] Preferably, the control module further includes:

[0048] The sleep control module is used to dynamically adjust the carbon dioxide concentration during a specified sleep period to improve sleep quality.

[0049] The sleep control module is used to obtain the sleep time period and the optimal carbon dioxide concentration range input by the input module, and to control the indoor carbon dioxide concentration range to remain within the optimal carbon dioxide concentration range during the sleep time period.

[0050] Compared with the prior art, the present invention has the following beneficial effects:

[0051] This invention uses motion posture to reflect changes in environmental quality. When pollution intensifies, the vibration frequency increases, thus intuitively reflecting changes in indoor environmental quality. Through ecological data visualization design, such as mapping pollution levels through butterfly movement frequency / color changes, the threshold for data understanding is lowered.

[0057] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0058] like Figures 1 to 3 The illustrated intelligent bionic butterfly device for environmental monitoring includes a base 101 and further includes:

[0059] The butterfly wing 1 is mounted on the top of the base 101 via the support rod 102;

[0060] The drive assembly, installed on the top of the support rod 102, is used to drive the flapping of the butterfly wing 1 to control the flapping frequency of the butterfly wing 1.

[0061] The control module 4, installed inside the base 101, is used to monitor air quality indicators in real time and to build a dynamic monitoring network.

[0062] The warning component, installed on butterfly wing 1, is used to map the pollution level by changing the color of light.

[0063] Enclosed spaces such as homes, offices, and classrooms are prone to accumulating high concentrations of pollutants such as CO2, PM2.5, and VOCs. Long-term exposure can lead to respiratory diseases, decreased attention, and pathological "building syndrome." Environmental data is often presented in the form of professional charts, which are difficult for the public to understand intuitively, resulting in delays in environmental protection actions.

[0064] This embodiment of the invention can solve the above problems. The specific implementation is as follows: when the control module 4 detects that the control quality of the indoor environment is not up to standard, the control module 4 controls the drive component to start. The drive component drives the double-wing mechanism to complete 3-15 adaptive vibration frequency movements per minute. The movement posture reflects the change in environmental quality. When the pollution intensifies, the vibration frequency increases, thereby intuitively reflecting the change in indoor environmental quality. Through ecological data visualization design, such as mapping the pollution level through the butterfly movement frequency / color change, the threshold for data understanding is reduced.

[0065] As an optional embodiment, the driving component includes:

[0066] Support frame 206 is fixed to the top of support rod 102;

[0067] The electric push rod 2 is fixed to one end of the support frame 206 via the mounting tube 201;

[0068] The movable rod 202 is fixed to the end of the telescopic rod of the electric push rod 2;

[0069] Two rotating sleeves 203 are rotatably installed inside the support frame 206 and are both sleeved on the outside of the moving rod 202. The two rotating sleeves 203 are respectively fixedly connected to the two wings of the butterfly wing 1.

[0070] Two guide slots 204 are respectively opened inside the two rotating sleeves 203 and are arranged symmetrically;

[0071] Two sliding contacts 205 are fixed to the side wall of the moving rod 202 and are slidably connected to the two guide grooves 204 respectively;

[0072] After the electric push rod 2 is started, it drives the moving rod 202 to move via the telescopic rod. The moving rod 202 drives the sliding contact 205 to move. The sliding contact 205 slides inside the guide groove 204. Under the action of the guide groove 204, it drives the rotating sleeve 203 to rotate. The rotating sleeve 203 drives the butterfly wing 1 to fan, thereby driving the butterfly wing 1 so that the butterfly wing 1 can adjust different fanning frequencies under different environmental pollution conditions.

[0073] As an optional embodiment, the driving component includes:

[0074] Two high-precision servo motors are used to drive the two wings of butterfly wing 1 to rotate, thereby driving butterfly wing 1 so that butterfly wing 1 can adjust different fanning frequencies under different environmental pollution conditions.

[0075] As an optional embodiment, the warning component includes:

[0076] Multiple LED lights 3 are fixed on the butterfly wing 1. The LED lights 3 are used to provide warnings by changing various light colors.

[0077] The LED light 3 installed on the butterfly wing 1 can change color according to the level of different pollutants. When the pollutant level exceeds the standard, the different color changes will serve as a warning. Furthermore, the light changes of the LED light 3 combined with the flapping of the butterfly wing 1 will increase the user's attention and improve the chances of the user noticing the warning. This will enhance the warning effect and will not cause panic like a sudden sound warning.

[0078] As an optional embodiment, the main body of Butterfly Wing 1 adopts a recycled aluminum alloy frame and a 3D printed castor oil-based resin skeleton, and the surface is covered with a PHBV / PLA biodegradable flexible membrane. 91% of the main structure is made of recyclable materials, and 93% of the components support biodegradation or closed-loop recycling after disposal.

[0079] As an optional embodiment, the control module 4 includes:

[0080] A carbon dioxide monitoring module is used to monitor the carbon dioxide content in the environment.

[0081] The VOCs monitoring module is used to monitor the VOCs gas content in the environment.

[0082] The PM2.5 monitoring module is used to monitor PM2.5 in the environment.

[0083] Temperature monitoring module, used to monitor ambient temperature;

[0084] Humidity monitoring module, used to monitor ambient humidity;

[0085] OLED display screen for real-time display of test data;

[0086] The WIFI module is used to connect and network the various modules.

[0087] The controller is used to activate the alarm component and start the linked air purifier when the values ​​detected by the carbon dioxide sensor, VOCs monitoring sensor, or PM2.5 sensor exceed the threshold, in order to purify the ambient air. When the value detected by the temperature sensor exceeds the temperature threshold, the controller is used to activate the alarm component and start the linked air conditioner to adjust the ambient temperature. When the value detected by the humidity sensor exceeds the threshold, the controller is used to activate the alarm component and start the linked humidifier or dehumidifier to regulate the ambient humidity.

[0088] Through multiple modules including carbon dioxide monitoring, VOCs monitoring, PM2.5 monitoring, temperature monitoring, and humidity monitoring, it can monitor 12 air quality indicators such as CO2, PM2.5, temperature, and humidity in real time. It supports dual-mode WiFi transmission, with a single base station covering a space of 200㎡. It supports multi-device cluster networking to build a dynamic monitoring network. Compared with traditional fixed monitoring equipment, while maintaining high-precision detection performance with a measurement error of ±3%, the power consumption under typical operating conditions is reduced to 2.1W, saving 87% energy, and the carbon footprint throughout the entire life cycle is reduced by 63%.

[0089] By monitoring CO2 concentration in real time, the system can be linked to a fresh air system or trigger a window opening reminder to avoid hypoxia and fatigue. The mobile monitoring network covers the blind spots of traditional fixed equipment, improving the comprehensiveness of monitoring. This addresses the problem that enclosed spaces such as homes, offices, and classrooms are prone to accumulating high concentrations of pollutants such as CO2, PM2.5, and VOCs. Long-term exposure can lead to respiratory diseases, decreased attention, and pathological "building syndrome." By innovatively integrating biomimetic mechanical technology with an intelligent environmental sensing system, the system achieves butterfly-like biomimetic movement through precision electromechanical transmission.

[0090] By using ecological data visualization design, such as mapping pollution levels through butterfly movement frequency / color changes, the threshold for data understanding is lowered. In educational scenarios, concrete data can be used to stimulate children's environmental awareness and promote behavioral changes, such as reducing outdoor activities on smoggy days. This addresses the problem that environmental data is often presented in the form of professional charts, which is difficult for the public to understand intuitively, leading to a lag in environmental action.

[0091] By triggering alarms in a timely manner and recording the spatial and temporal distribution of pollution, data support is provided for ventilation or purification, so as to solve the problem of local pollution that is easily overlooked, such as ozone release from printers in office spaces and excessive formaldehyde in newly renovated spaces.

[0092] By dynamically adjusting suggestions such as linking humidifiers / dehumidifiers, a healthy humidity range of 40%-60% can be maintained. Areas where air conditioning is overused can be identified, and energy consumption can be optimized to solve the problems of excessive humidity leading to mold growth, excessive humidity exacerbating respiratory discomfort, and temperature fluctuations affecting comfort and wasting energy.

[0093] It has a built-in LED intelligent light effect system that maps environmental parameters in real time through changes in color spectrum.

[0094] When designing the hardware circuit of the STM32-based bionic butterfly device, suitable environmental monitoring sensors, such as those for temperature, humidity, air quality, and air pressure, were selected for sensor selection and interface design. Appropriate interface circuits were also designed to ensure accurate and reliable acquisition and transmission of sensor data by the STM32 microcontroller. A stable power supply module was chosen, and filtering and voltage regulation measures were implemented to reduce the impact of power supply noise and fluctuations on system performance and ensure stable system operation. Based on the signal characteristics of the sensor output, corresponding signal processing circuits, such as analog-to-digital conversion circuits and filtering circuits, were designed to enhance signal accuracy and reliability and provide a good foundation for subsequent data processing. Suitable storage modules, such as memory chips or memory cards, and data transmission modules, such as Wi-Fi modules, were also designed. To facilitate the transmission of collected data to cloud servers or other target terminals, a user-friendly human-machine interface is designed, including an LCD screen, LED indicators, and a buzzer, allowing users to intuitively understand the system's operating status and monitoring data. The circuit design considers system safety, including overvoltage and overcurrent protection, and lightning protection, to ensure long-term stable operation and protect user equipment. A modular design is adopted, enabling each part of the system to operate independently and facilitating maintenance and upgrades. Low-power characteristics are emphasized during circuit design, employing appropriate power management schemes such as using low-power components, implementing dynamic power management, and optimizing clock frequency to extend system operating time and reduce energy consumption, ultimately constructing a stable, efficient, safe, and reliable hardware circuit.

[0095] By combining Keil uVision5 and Altium Designer, a complete software and hardware development environment is provided for STM32 development. Keil 5 provides developers with a comprehensive development environment that supports multiple development stages, including code writing, compilation, debugging, and simulation. It supports high-level programming languages ​​such as C / C++, and uses Keil 5's built-in compiler to convert the code into machine code that the microcontroller can execute. At the same time, the debugging tools provided by Keil 5, including single-step execution, breakpoint setting, and variable viewing, greatly simplify the process of error troubleshooting and program optimization. Keil uVision5 also supports use with various simulators, making it convenient for developers to test and debug programs without actual hardware.

[0096] During STM32 development, Altium Designer provides developers with support from circuit schematic design to PCB layout and routing. By drawing circuit schematics, the connection relationships between various electronic components are clearly shown, and the software's simulation function is used for verification, thereby ensuring the correctness and reliability of the circuit design. After entering the PCB design stage, the toolset provided by Altium Designer enables developers to perform layout and routing work efficiently, ensuring that the final hardware circuit board can meet actual requirements and be perfectly integrated with microcontrollers such as STM32. By using Altium Designer for hardware circuit design, developers can complete STM32 development tasks more conveniently and accurately.

[0097] The MQ-2, MQ-7, MQ-135 and other environmental sensors have some similarities in programming. First, there is the initialization and configuration of the interface. Regardless of the type of gas sensor, we need to initialize and configure the corresponding interface of STM32, such as GPIO, ADC or I2C. This is the basis for ensuring that the sensor can work properly and communicate with STM32.

[0098] In summary, although different gas sensors may differ in their specific implementations, they share some commonalities in STM32 programming. These commonalities mainly lie in interface initialization and configuration, data acquisition and processing, data transmission and storage, and user interface design. Figure 4 This is a code example of the main part of the MQ-2 sensor program design. For other sensors, such as MQ-7 and MQ-135, the code structure and logic are generally similar, but the specific configuration and data processing parts may differ.

[0099] This invention selects the high-performance ESP32 module as the data transmission terminal and establishes a connection with a self-built cloud service platform using a stable and reliable TCP communication protocol. To ensure the security and uniqueness of data transmission, each device uses a unique key for access authentication. This authentication method is based on advanced encryption algorithms and security protocols, effectively preventing data theft and tampering, and ensuring the safe and stable operation of the IoT system. The ESP32 module undertakes the important task of efficiently sending various types of collected data, such as real-time sensor monitoring data and device operating status data, to Buffalo Cloud. After receiving this data, the cloud service platform will classify, clean, store, and analyze the data according to pre-set intelligent algorithms and data processing rules. The processed data is presented to users in an intuitive and easy-to-understand way through a carefully designed APP interface. Users can monitor device status and view historical data in real time anytime and anywhere through the mobile APP, and realize remote control and management of devices, thereby achieving real-time monitoring and intelligent management of the entire IoT system. When the data is successfully displayed on the APP, it means that the development board and the APP have been successfully paired and a stable and reliable connection has been established. The entire development process fully leverages the ease of use, powerful data processing capabilities, and stable communication capabilities of the cloud service platform and the ESP32 module, greatly shortening the development cycle of IoT applications, reducing development costs, and providing strong technical support for the rapid iteration and innovative development of IoT applications.

[0100] As an optional embodiment, the control module 4 further includes:

[0101] The input module is used to input the monitoring thresholds of each monitoring module;

[0102] The outdoor monitoring module is used to monitor the levels of PM2.5 and VOCs in the outdoor environment.

[0103] The controller is used to acquire the monitoring values ​​from the carbon dioxide monitoring module. When the monitoring value exceeds the threshold, the controller is used to control the outdoor monitoring module to start in order to monitor the outdoor environmental values.

[0104] The controller is also used to acquire outdoor monitoring values ​​from the outdoor monitoring module. When the outdoor monitoring values ​​are all within the normal range, it controls the smart window to open and sends window opening information to the user.

[0105] When the outdoor monitoring value exceeds the threshold, the control unit controls the activation of the linked camera to monitor indoor human activities. If no one is detected indoors, no additional control is performed. If human activities are detected indoors, the control unit controls the activation of the linked fresh air system to filter and replace the indoor air environment.

[0106] Users can input the detection thresholds for various gases in the environment through the input module; these thresholds are called monitoring thresholds. The carbon dioxide monitoring module detects the carbon dioxide content in the indoor air and sends the detected value to the controller. The controller then compares the detected value with the monitoring threshold. If the value exceeds the threshold, it indicates that the carbon dioxide content in the indoor environment has exceeded the threshold. In this case, the carbon dioxide content in the indoor environment needs to be reduced to make the indoor environment suitable for human activity. Therefore, the controller activates the outdoor monitoring module to monitor the outdoor environment. After monitoring, the outdoor monitoring module sends the outdoor monitoring value to the controller. When the detected outdoor monitoring value is within the normal range, the controller controls the linked smart window to open, thereby ventilating the indoor environment and improving air quality. The system circulates and replaces ambient air to reduce the carbon dioxide content in the indoor environment. When the detected outdoor monitoring value is outside the normal range and exceeds the threshold, the smart window remains closed, and the controller activates the linked camera. The camera rotates to detect whether there is any activity inside. If no one is inside, the high carbon dioxide content will not interfere with people's activities, and the controller will not take any additional action. However, if people are inside, the carbon dioxide content needs to be reduced immediately. At this time, the controller activates the linked fresh air system to replace the ambient air in the room. During the replacement process, the ambient air is filtered to remove harmful substances and excessive carbon dioxide, thus achieving the filtration and replacement of the indoor environment and restoring the carbon dioxide content to a normal level, making the indoor environment suitable for human activity.

[0107] As an optional embodiment, the control module 4 further includes:

[0108] The time control module is used to adjust the start-up time of the fresh air system based on the arrival time input by the input module;

[0109] The time control module is used to obtain the final value A0 of carbon dioxide concentration control through the input module, obtain the current carbon dioxide concentration value A1 through the carbon dioxide monitoring module, and obtain the change value A2 of carbon dioxide concentration adjusted by the fresh air system within a specified time t through the input module.

[0110] The time control module is used to calculate the remaining time T based on the time of returning home, and to control the carbon dioxide monitoring module to monitor the carbon dioxide concentration at specified time intervals t to obtain the change value A of the indoor carbon dioxide concentration at each specified time interval t. When the change value A of the carbon dioxide concentration is less than 0, the carbon dioxide concentration adjustment time T1 is calculated according to T1=A1-A0 / |A|. When the calculated remaining time T is greater than or equal to the carbon dioxide concentration adjustment time T1, no additional control is performed.

[0111] When the remaining time T is less than the carbon dioxide concentration adjustment time T1, the time control module calculates the total operating time T2 of the fresh air system based on T2=A1-A0+∣A∣T / A2-∣A∣, and calculates the fresh air system opening time based on the return time and the total operating time T2 of the fresh air system. The controller controls the fresh air system to open on a timed basis according to the fresh air system opening time of the time control module.

[0112] Users can input their expected return time and the final carbon dioxide concentration control value A0 through the input module. Here, the final carbon dioxide concentration control value A0 is the final value adjusted when adjusting the indoor carbon dioxide concentration. Users can also input the carbon dioxide concentration change value A2 of the linked fresh air system within a specified time t through the input module. Here, A2 varies depending on the linked fresh air system and is input by the user.

[0113] The time control module can obtain the final carbon dioxide control value A0 from the input module, and obtain the current carbon dioxide concentration A1 from the carbon dioxide monitoring module. It can also obtain the carbon dioxide concentration change value A2 of the fresh air system within a specified time t from the input module, and obtain the time of arrival home from the input module. Then, the controller calculates the remaining time T based on the time of arrival home and the current time. At this time, the controller controls the carbon dioxide monitoring module to start, and monitors the carbon dioxide concentration at the beginning and end of the specified time interval t to obtain the carbon dioxide concentration change value A in the indoor environment under natural conditions at each specified time interval t.

[0114] When the carbon dioxide concentration change value A is less than 0, the indoor carbon dioxide concentration gradually decreases under natural conditions. For example, if there are multiple potted plants indoors, the plants can convert carbon dioxide. If the carbon dioxide concentration A1 exceeds the final carbon dioxide regulation value A0, the controller calculates the carbon dioxide concentration adjustment time T1 based on T1 = A1 - A0 / |A|. That is, under natural conditions, the carbon dioxide concentration adjustment time T1 can adjust the carbon dioxide concentration to the final carbon dioxide regulation value A0. If the remaining time T is greater than or equal to the carbon dioxide concentration adjustment time T1, the indoor carbon dioxide concentration can change to the final carbon dioxide regulation value A0 on its own without additional control.

[0115] When the remaining time T is less than the carbon dioxide concentration adjustment time T1, it means that the carbon dioxide concentration in the indoor environment cannot reach the final carbon dioxide control value A0 under natural conditions before the user returns home. At this time, the time control module calculates the total operating time T2 of the fresh air system according to T2 = A1 - A0 + |A|T / A2 - |A|. That is, the fresh air system is turned on for a total operating time T2 before the user returns home, which can reduce the carbon dioxide concentration to the final carbon dioxide control value A0. At this time, the controller calculates the fresh air system opening time according to the total operating time T2 and the user's return home time. Then, the controller controls the fresh air system to turn on at regular intervals according to the fresh air system opening time, so that the indoor carbon dioxide concentration can be reduced to the final carbon dioxide control value A0 when the user returns home.

[0116] This allows users to adjust the indoor carbon dioxide concentration to the final control value A0 before returning home via intelligent control. After returning home, users can intuitively view the control results by observing the status and vibration frequency of the butterfly wing 1, which helps improve the safety of the user's environment. Furthermore, intelligent control of the fresh air system helps save energy and avoids energy loss caused by the long-term operation of the fresh air system.

[0117] As an optional embodiment, the control module 4 further includes:

[0118] When the carbon dioxide concentration change value A equals 0, the time control module calculates the total operating time T3 of the fresh air system based on T3 = A1 - A0 / A2, and calculates the fresh air system operating time based on the time of returning home and the total operating time T3. The controller controls the fresh air system to start on a timed basis according to the fresh air system operating time of the time control module.

[0119] When the carbon dioxide concentration change value A equals 0, it means that the indoor environment cannot regulate carbon dioxide on its own. At this time, it is necessary to rely entirely on the fresh air system. The time control module calculates the total operating time T3 of the fresh air system according to T3 = A1 - A0 / A2, and calculates the operating time of the fresh air system according to the time of returning home. In order to control the fresh air system to complete the purification of the indoor environment when the user returns home, while relying entirely on the fresh air system.

[0120] As an optional embodiment, the control module 4 further includes:

[0121] When the carbon dioxide concentration change value A is greater than 0, the controller immediately controls the activation of the linked fresh air system and sends a warning message to the user to warn the user that there is an abnormality in the indoor combustion equipment.

[0122] When there is no biological activity indoors, the carbon dioxide content will not rise sharply under natural conditions. When the carbon dioxide concentration change value A is greater than 0, it indicates that there is an abnormality in the indoor environment, which may be due to gas leakage or abnormal combustion in the indoor combustion equipment. At this time, it is necessary to urgently alert the user. The controller generates a warning message and sends the warning message to the user's terminal so that the user can receive the warning message to remind the user of the abnormality in the indoor environment and remind the user to take appropriate action to avoid major adverse effects.

[0123] As an optional embodiment, the control module 4 further includes:

[0124] The sleep control module is used to dynamically adjust the carbon dioxide concentration during a specified sleep period to improve sleep quality.

[0125] The sleep control module is used to obtain the sleep time period and the optimal carbon dioxide concentration range input by the input module, and to control the indoor carbon dioxide concentration range to remain within the optimal carbon dioxide concentration range during the sleep time period.

[0126] Users can input their sleep time period and optimal carbon dioxide concentration range through the input module. The sleep control module can obtain the sleep time period and optimal carbon dioxide concentration range from the input module. When the time is within the sleep time period, the sleep control module controls the fresh air system to start and control the indoor carbon dioxide concentration range to maintain the optimal carbon dioxide concentration range in order to maintain a good sleep environment.
