Description

Technical Field

[0001] This invention relates to the field of smart home devices and environmental sensing technology, specifically to a weather display system that senses the environment and phenology, and its e-ink screen. Background Technology

[0002] With the rapid development of smart home and environmental sensing technologies, users' demands for home devices have shifted from simple functionality to a comprehensive pursuit of value that combines practicality, cultural connotation, and immersive interactive experience. Traditional devices that only meet basic functions can no longer satisfy modern users' aspirations for aesthetic and emotional value. In the field of weather information display, the following are some typical solutions: Traditional weather bottles: a type of decorative item based on chemical principles. The solution inside the bottle will produce different crystal forms according to changes in ambient temperature. However, its function is limited. It can only roughly reflect temperature changes and cannot provide accurate practical data such as humidity and soil moisture. Moreover, it does not involve time and cultural dimensions such as the twenty-four solar terms. Its decorative function is greater than its practical function. Ordinary electronic weather screens typically collect data such as temperature and humidity through sensors and display it on an LCD or LED screen in the form of numbers or simple graphical icons. This display method presents data in a rigid and cold way, lacking artistic beauty and cultural connotation, and the user experience is monotonous. Electronic display devices with cultural elements: Some devices attempt to embed traditional patterns or elements into the interface to enhance aesthetics, but their screens are mostly fixed settings or a limited number of switching modes, which cannot be deeply linked with real-time changing environmental parameters or the dynamic flow of the twenty-four solar terms. This results in a disconnect between cultural elements and practical functions, failing to achieve true "fusion of scene and emotion".

[0003] Therefore, a weather display system that senses the environment and phenology is needed, along with its e-ink screen, to improve the above-mentioned problems. Summary of the Invention

[0004] To address the issues of limited functionality and data dimensionality, this invention provides a weather display system and its e-ink screen that senses the environment and phenology, thereby resolving the aforementioned problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A weather display system that senses the environment and phenology includes a sensing layer, a transmission layer, a processing layer, and a display layer. Each layer is linked together through a standardized communication protocol to form a closed-loop link of "data acquisition-transmission-processing-presentation".

[0006] The sensing layer includes a soil moisture sensor and an air temperature and humidity sensor, which are used to collect soil moisture, air temperature and humidity data, and are connected to the transmission layer via a wired connection.

[0007] The transmission layer uses an ESP32 series microcontroller to receive raw data from the sensing layer and convert it into digital signals, which are then transmitted to the processing layer via serial port or LoRa wireless communication.

[0008] The processing layer includes a computer device with a pre-installed control program. The control program has a built-in tag rule module, a traditional Chinese ink painting material library, a decision model, and a planting suggestion database. It is used to receive data from the transmission layer and perform parsing, tag generation, painting matching, and content integration operations.

[0009] The display layer uses an electronic ink screen to receive and synchronously display the display content sent by the processing layer. The display content includes ink paintings, environmental data, real-time time, and planting suggestions.

[0010] As a preferred embodiment of the present invention, the sensing layer also includes an optional rain sensor or light sensor. All sensors are wired to the transmission layer via a 485 bus to ensure data transmission stability.

[0011] As a preferred embodiment of the present invention, the microcontroller of the transmission layer can be replaced with an Arduino series motherboard. The microcontroller integrates a fault detection module, which provides an indicator light when the sensor connection is abnormal.

[0012] As a preferred embodiment of the present invention, the label rule module of the processing layer classifies environmental parameters and seasonal information into temperature labels (T0-T3), humidity labels (H0-H2), soil moisture labels (S0-S2), and seasonal labels (Se0-Se3), and combines them to form a comprehensive label of "temperature label + humidity label + soil moisture label + seasonal label".

[0013] As a preferred embodiment of the present invention, the ink painting material library contains ink paintings corresponding to 108 comprehensive tags, the themes of the paintings are consistent with the 24 solar terms and environmental parameter characteristics, and batch updates are supported.

[0014] As a preferred embodiment of the present invention, the decision model is constructed based on the "tag-painting" mapping rule, which can accurately match comprehensive tags with paintings in the ink painting material library, and the mapping rule can be dynamically modified.

[0015] As a preferred embodiment of the present invention, the electronic ink screen of the display layer is 4.7 inches with a resolution of not less than 1280×720, supports 16 levels of grayscale display, and the display layout adopts the method of "ink painting as background, and practical information superimposed in a semi-transparent manner".

[0016] As a preferred embodiment of the present invention, the e-ink screen communicates with the processing layer through the ESP32 driver module, supports wired or wireless connection, and can simultaneously display ink paintings, environmental data, real-time time and planting suggestions, and has the characteristics of low power consumption and paper-like display.

[0017] As a preferred embodiment of the present invention, the display steps of the e-ink screen include: Data acquisition and transmission steps: Environmental parameters are collected by sensors in the perception layer and sent to the processing layer via the transmission layer.

[0018] Data parsing and tag generation steps: The processing layer parses environmental parameters and obtains local time, and generates multi-dimensional environmental tags according to preset rules.

[0019] Ink painting matching and data integration steps: The processing layer matches the multi-dimensional environment label with the pre-stored ink painting material library to obtain the corresponding ink painting, and retrieves planting suggestions that are suitable for the current environment label from the plant maintenance knowledge base. It integrates environmental data, time and planting suggestions to generate display data.

[0020] Content display steps: The display data is sent to the e-ink screen for display. The e-ink screen uses ink painting as the background and displays digital environmental parameters, current time and planting suggestions in the foreground section.

[0021] Compared with existing technologies, this invention breaks through the dilemma of existing devices being either "pure data" or "pure decoration." It retains core practical data such as temperature, humidity, and soil moisture to meet users' needs for environmental monitoring and planting maintenance. At the same time, it transforms cold data into an artistic presentation through the artistic conception of ink painting, making the product both a tool and an aesthetic value. It can be used as a home decoration and cultural ornament to improve the quality of life.

[0022] This invention achieves dynamic matching of "real-time environmental parameters (spatial dimension) + 24 solar terms (time dimension) + traditional ink painting (cultural dimension)," which is different from the static pattern design of existing devices with cultural elements. Under the same solar term, if the ambient temperature and humidity change, the color tone and details of the ink painting will be adjusted accordingly. Under the same environmental parameters, the theme of the picture will automatically switch when crossing solar terms, making the cultural connotation more vivid and enhancing the user's emotional resonance and cultural identity.

[0023] The labeling rules, ink painting material library, and planting suggestion database of this invention all support flexible updates. Users can add new paintings, adjust label classification standards, or supplement maintenance rules for specific green plants according to their own preferences. The hardware modules adopt a standardized design, and components such as sensors and microcontrollers can be replaced as needed (such as replacing the DHT11 sensor with the more accurate SHT30 sensor) to adapt to the personalized and professional needs of different users.

Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0026] Example 1: Please refer to Figure 1-3 The weather display system shown includes a sensing layer, a transmission layer, a processing layer, and a display layer. Each layer is linked together through a standardized communication protocol to form a closed-loop link of "data acquisition-transmission-processing-presentation".

[0027] The sensing layer includes a soil moisture sensor and an air temperature and humidity sensor, which are used to collect soil moisture, air temperature and humidity data, and are connected to the transmission layer via wired connection.

[0028] in: Soil moisture sensor: A capacitive soil moisture sensor is used, which is buried in the soil of potted plants or the target monitoring area. The measurement range is 0-100%RH, and the accuracy is ±2%RH. It is used to collect soil moisture data and provide a basis for planting suggestions.

[0029] Air temperature and humidity sensor: The DHT11 temperature and humidity sensor is selected and placed in a ventilated area of ​​the target environment. The temperature measurement range is 0-50℃ (accuracy ±2℃) and the humidity measurement range is 20-90%RH (accuracy ±5%RH). It is used to collect air temperature and humidity data.

[0030] The transmission layer uses an ESP32-N4 microcontroller to receive raw data from the sensing layer and convert it into digital signals, which are then transmitted to the processing layer via serial port or LoRa wireless communication.

[0031] The processing layer includes computer devices with pre-installed control programs. The control programs have built-in tag rules modules, ink painting material libraries, decision models, and planting suggestion databases. They are used to receive data from the transmission layer and perform parsing, tag generation, painting matching, and content integration operations.

[0032] The computer sends the content data package to the e-ink screen. Upon receiving the data, the e-ink screen updates the displayed content according to a preset layout (a full-screen ink painting as the background, with environmental data, time, and planting suggestions displayed in semi-transparent white text overlaid in the lower 1 / 4 area of ​​the screen). When environmental parameters change, causing labels to change, or when the time spans a solar term, the system automatically triggers a re-matching and display update, requiring no manual operation from the user.

[0033] The transmission layer and processing layer are connected via a LoRa radio communication module for long-distance, low-power data transmission, while the transmission layer and sensing layer are connected via an I2C bus or a single-bus protocol.

[0034] The planting suggestions integrated in the processing layer are derived from a pre-stored plant care knowledge base. This knowledge base outputs care tips for common household ornamental plants based on the seasonal and soil moisture indicators in the multi-dimensional environmental tags.

[0035] The database contains care requirements for common houseplants (such as pothos, succulents, spider plants, and money trees), providing suggestions based on a dual dimension of "soil moisture + season." For example, when the tag is "S0Se1" (soil is dry, summer), the suggestion for pothos is "The soil moisture is low today. Water evaporates quickly in summer, so it is recommended to slowly water along the edge of the pot until the water drains to the bottom." When the tag is "S2Se3" (soil is wet, winter), the suggestion for succulents is "The soil moisture is too high. Succulents are dormant in winter and watering should be reduced. It is recommended to drain excess water and place the succulent in a well-ventilated area." The database allows users to add new plant types and care rules to improve product applicability.

[0036] The processing layer, as the core control unit of the system, is responsible for core logic such as data parsing, tag generation, and content matching. It is implemented using a standard home or industrial-grade computer and comes pre-installed with a custom-developed control program (based on Python or C++). Specific functions include: Data reception and cleaning: Receive digital signals sent by the transport layer, filter out abnormal data using denoising algorithms (such as moving average method), and extract valid values; Time and phenology recognition: The computer's local clock module is called to obtain the real-time time (year, month, day, hour, minute), and combined with the built-in 24 solar terms database (including the specific date range of each solar term and its corresponding seasonal attributes), the current solar term and season identifier are determined. Tag generation: Classify environmental parameters and seasonal information according to preset rules to generate standardized tags; Content matching and integration: The generated tags are matched with a pre-stored ink painting material library through a decision model, and environmental data, real-time data and corresponding planting suggestions are integrated to form the final display content data package; Command transmission: Send the display content data packet to the display layer via wired (USB) or wireless (Wi-Fi) means.

[0037] The display layer uses an e-ink screen to receive and synchronously display the content sent by the processing layer. The displayed content includes ink paintings, environmental data, real-time time, and planting suggestions.

[0038] In this embodiment, the sensing layer also includes one or more of a rain sensor, a light sensor, or an ultrasonic distance sensor. The system automatically adjusts the level of detail of the displayed content or triggers the display switch based on the user distance detected by the ultrasonic distance sensor. All sensors are wired to the transmission layer via a 485 bus to ensure data transmission stability.

[0039] In this embodiment, the microcontroller of the transmission layer can be replaced with an Arduino series motherboard. The microcontroller integrates a fault detection module, which provides an indicator light when the sensor connection is abnormal.

[0040] In this implementation, the labeling rule module of the processing layer classifies environmental parameters and seasonal information into temperature labels (T0-T3), humidity labels (H0-H2), soil moisture labels (S0-S2), and seasonal labels (Se0-Se3), and combines them to form a comprehensive label of "temperature label + humidity label + soil moisture label + seasonal label".

[0041] For the seasonal identifier Se0, the matching artwork theme is spring scenery, including buds, peach blossoms, and drizzle; For the seasonal identifier Se1, the matching painting theme is summer scenery, including lotus flowers, sudden rain, and dense shade; For the seasonal identifier Se2, the matching artwork theme is autumn scenery, including maple leaves, withered lotus leaves, and the bright moon; For the seasonal identifier Se3, the matching artwork theme is winter scenery, including bare branches, snow scenes, and winter plum blossoms; Meanwhile, for different humidity levels H0, H1, and H2, paintings with the same seasonal theme present different brushstroke effects: dry, moist, and hazy.

[0042] In this implementation, the ink painting material library contains ink paintings corresponding to 108 comprehensive tags. The themes of the paintings match the 24 solar terms and environmental parameter characteristics, and batch updates are supported.

[0043] The resource library is built on a dual-dimensional basis of "solar term theme + environmental characteristics," containing 108 ink paintings corresponding to comprehensive tags. All paintings are original or legally authorized to avoid copyright disputes. The creation standards for the paintings include: ① Seasonal relevance: The elements of the painting match the corresponding season (e.g., spring includes tender buds and peach blossoms, winter includes snow and plum blossoms); ② Environmental adaptability: The color tone matches the temperature and humidity (e.g., high temperature T3 corresponds to warm colors, low temperature T0 corresponds to cool colors); ③ Cultural connotation: The painting incorporates the traditional customs or cultural symbols of the corresponding solar term (e.g., Qingming includes kites, Dragon Boat Festival includes mugwort). The resource library is stored in the form of image files on the processing layer computer and supports batch updates through the program, making it easy to expand new tags and paintings.

[0044] The comprehensive tags specifically include: Temperature values ​​are mapped to temperature labels according to the following rules: temperatures below 10℃ correspond to T0, temperatures between 10℃ and 20℃ correspond to T1, temperatures between 20℃ and 30℃ correspond to T2, and temperatures above or equal to 30℃ correspond to T3.

[0045] Humidity values ​​are mapped to humidity labels, with the following mapping rules: humidity below 30% corresponds to H0, humidity between 30% and 60% corresponds to H1, and humidity above or equal to 60% corresponds to H2.

[0046] Soil moisture values ​​are mapped to soil moisture labels, with the following mapping rules: soil moisture below 30% corresponds to S0, soil moisture between 30% and 70% corresponds to S1, and soil moisture above or equal to 70% corresponds to S2.

[0047] The local real-time time determines the corresponding one of the 24 solar terms and maps it to a seasonal identifier. The mapping rules are as follows: Beginning of Spring, Rain Water, Awakening of Insects, Spring Equinox, Pure Brightness, and Grain Rain correspond to Se0; Beginning of Summer, Grain Buds, Grain in Ear, Summer Solstice, Minor Heat, and Major Heat correspond to Se1; Beginning of Autumn, End of Heat, White Dew, Autumn Equinox, Cold Dew, and Frost's Descent correspond to Se2; Beginning of Winter, Minor Snow, Major Snow, Winter Solstice, Minor Cold, and Major Cold correspond to Se3.

[0048] The temperature label, humidity label, soil moisture label, and season label are combined in sequence to form a comprehensive label.

[0049] In this implementation, the decision model is built based on the "label-painting" mapping rule, which can accurately match comprehensive labels with paintings in the ink painting material library, and the mapping rule can be dynamically modified.

[0050] The decision-making model is built using a rule engine, with the core being a "tag-artwork" mapping table. The table pre-sets the path of the artwork file corresponding to each valid comprehensive tag. The model's workflow is as follows: ① Receive comprehensive tags, ② Query the mapping table to obtain the corresponding artwork path, ③ Call the artwork file and integrate it with other display content. The model supports dynamic rule updates, and users can modify the correspondence between tags and artworks through the program interface to adapt to personalized needs.

[0051] In this invention, the e-ink screen of the display layer is 4.7 inches with a resolution of no less than 1280×720, supports 16 levels of grayscale display, and the display layout adopts the method of "ink painting as background, with practical information superimposed in a semi-transparent way".

[0052] In this embodiment, the e-ink screen communicates with the processing layer through the ESP32 driver module, supports wired or wireless connections, and can simultaneously display ink paintings, environmental data, real-time time and planting suggestions. It has the characteristics of low power consumption and paper-like display.

[0053] In this embodiment, the display steps of the e-ink screen include: Data acquisition and transmission steps: Environmental parameters are collected by sensors in the perception layer and sent to the processing layer via the transmission layer.

[0054] Data parsing and tag generation steps: The processing layer parses the environment parameters and obtains the local time, and generates comprehensive tags according to preset rules.

[0055] Ink painting matching and data integration steps: The processing layer matches the comprehensive tags with the pre-stored ink painting material library to obtain the corresponding ink painting, and retrieves planting suggestions that are suitable for the current environment tags from the plant care knowledge base. It integrates environmental data, time and planting suggestions to generate display data.

[0056] Content display steps: The display data is sent to the e-ink screen for display. The e-ink screen uses ink painting as the background and displays digital environmental parameters, current time and planting suggestions in the foreground section.

[0057] The specific usage steps of the above embodiments are as follows: Sensing layer deployment: Bury the capacitive soil moisture sensor in the indoor potted soil (5-10cm deep, avoid contact with the bottom of the flowerpot), and fix the DHT11 sensor in a ventilated place next to the flowerpot, 10-20cm away from the soil surface, avoiding direct sunlight.

[0058] Transmission layer connection: Connect the two sensors to the corresponding interfaces of the ESP32-N4 microcontroller via the 485 bus, and connect the ESP32-N4 to a 5V power supply. If the distance between the computer and the device exceeds 5 meters, connect the LoRa module to the ESP32-N4 and install an antenna.

[0059] Processing layer configuration: Install a custom control program (including label rules, ink painting material library, and planting suggestion database) on your computer, and connect the computer to the ESP32-N4 via USB cable or Wi-Fi to complete communication pairing.

[0060] Display layer deployment: Connect the e-ink screen to the ESP32 driver board, pair the driver board with the computer via USB cable or Wi-Fi, place the e-ink screen on the desktop or hang it on a stand to ensure the display is clear and visible.

[0061] Taking "Indoor potted plant environment during Xiaoman season (Summer Se1)" as an example, the system operation process is as follows: Data acquisition: The DHT11 collected air temperature of 26℃ and humidity of 55%RH, and the soil moisture sensor collected soil humidity of 65%RH. The sensors transmitted the raw data to the ESP32-N4 via the 485 bus.

[0062] Data transmission: The ESP32-N4 converts data into digital signals and sends them to the computer via Wi-Fi.

[0063] Data processing: After the computer program cleans the data, it determines that the current time is Xiaoman (corresponding to season Se1) and generates the label "T2H1S1Se1".

[0064] Content matching: The decision model matches a traditional Chinese ink painting depicting "the Lesser Fullness of Grain season, warm and humid, with lush green plants growing vigorously," and calls the corresponding planting suggestion: "Today is Lesser Fullness of Grain, the soil moisture is suitable, the pothos is growing vigorously, and proper ventilation is recommended."

[0065] Display Update: The computer sends the ink painting, "Temperature 26.0℃, Humidity 55.0%RH, Soil Moisture 65.0%RH", "May 21, 2025, 10:30, Xiaoman", and planting suggestions to the e-ink screen. The e-ink screen updates the displayed content, completing one cycle.

[0066] Example 2: A weather display system based on the above-described Example 1, which senses the environment and phenology, includes the following alternative solutions: Sensors: The air temperature and humidity sensor can be replaced by DHT22, SHT30 or other models instead of DHT11, and the soil moisture sensor can be replaced by other types such as resistive or capacitive sensors. The core requirement is to meet the data acquisition accuracy requirements. Transport layer: ESP32 can be replaced with microcontrollers with data transmission capabilities such as ESP8266 and Arduino UNO, and the communication method can be changed from serial port to wireless transmission such as WiFi and Bluetooth; Display layer: The 4.7-inch e-ink screen can be replaced with a larger e-ink screen or a low-power LCD screen, with the core requirements of low power consumption and the ability to display images and text. Processing layer: A regular computer can be replaced with an embedded development board (such as a Raspberry Pi), the core of which satisfies the functions of program execution, data processing and storage.

[0067] Tag generation rules: The threshold ranges for temperature, humidity, and soil moisture can be adjusted according to the usage scenario (e.g., the T3 range can be refined in high-temperature environments), and the division of solar terms and seasons can be adjusted according to regional customs. Ink painting matching method: The pre-stored material library can be replaced with AI-generated ink painting images in real time. The ink painting is dynamically drawn according to the tag features by the algorithm, without the need for pre-stored materials; Data transmission protocol: Serial communication can be replaced with network protocols such as MQTT and HTTP to adapt to wireless transmission scenarios.

[0068] All standard parts used in this application can be purchased from the market. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art and are also general components, which are common knowledge in this field.

[0069] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
