Description

Technical Field

[0001] The present invention relates to the technical field of intelligent household appliances. Background Art

[0002] With the rapid development of smart home appliance technology, smart home products have gradually become a part of modern life. Among them, smart flower pots, as an emerging branch in the field of smart homes, have received extensive attention and research both at home and abroad in recent years.

[0003] At present, in the field of smart flower pots, the foreign market has shown a high degree of maturity and innovation. For example, the "Plantroid" flower pot robot developed by Tokyo University of Agriculture and Technology in 2017 is not only solar-powered and autonomously mobile, but also can automatically adjust its position according to the light requirements of plants to optimize photosynthesis efficiency. In addition, the Tulipe smart flower pot designed by British college students, the Click and Grow smart flower pot inspired by NASA, and the smart flower pot that can interact with the owner through sound, all show the diversity of foreign innovation in smart flower pot technology. Most of these products realize the preliminary monitoring and regulation of the plant growth environment by integrating light, temperature and humidity sensors, but there is still room for improvement in system integration and user experience.

[0004] Domestic research in the field of smart flower pots started late, but has developed rapidly in recent years. The home smart watering device designed by Zhang Zhaopeng in 2022 realizes automatic watering and differentiated control of flowers, reflecting the domestic progress in smart watering technology. At the same time, the all-weather plant hosting system based on the Arduino platform and the smart flower pot products designed using the KANO model all demonstrate the country's active exploration and innovation in the field of smart flower pots. However, compared with other smart home products in China, the market penetration rate of smart flower pots is still relatively low, and existing products still need to be improved in terms of intelligence, user interaction experience and system stability.

[0005] Although remarkable achievements have been made in the field of smart flower pots at home and abroad, the following major problems still exist: 1. Insufficient sensor accuracy and stability: The sensors used in some smart flower pots are not very accurate and are easily affected by environmental interference, resulting in inaccurate data and affecting the accuracy of decisions such as watering and fertilizing.

[0006] 2. Limited degree of intelligence: Some smart flower pots on the market only have basic watering functions and lack personalized maintenance plans for different plant characteristics.

[0007] 3. Poor user experience: Some smart flower pots are complicated to operate, making it difficult for users to get started quickly; at the same time, there is a lack of timely feedback mechanism, and users cannot understand the status of the plants in a timely manner.

[0008] 4. Insufficient ability to prevent pests and diseases: Traditional smart flower pots often ignore pest and disease prevention, or only provide simple reminder functions, which cannot effectively help users prevent pests and diseases.

[0009] 5. Lack of customized services: Many smart flower pots on the market lack customized services tailored to users’ specific needs and cannot meet the personalized needs of different users. Summary of the invention

DETAILED DESCRIPTION

[0041] In order to clearly illustrate the technical features of this patent, this patent is elaborated in detail below through a specific implementation method and in combination with its accompanying drawings.

[0042] Considering the following defects of the prior art: 1. Sensor accuracy and stability issues: The existing products’ sensors are not accurate and stable enough, which leads to inaccurate monitoring data and affects plant maintenance decisions. They lack adaptability to different types of plants and cannot meet the growth needs of different plants.

[0043] 2. Image recognition algorithm problem: The image recognition algorithm of existing products is not accurate enough, and it is easy to misjudge the growth status of plants, leading to wrong maintenance decisions. It lacks the ability to handle complex scenes, such as light changes, occlusion and other factors.

[0044] 3. Intelligent control algorithm problem: The intelligent control algorithm of existing products is not perfect enough to perform accurate maintenance operations according to the actual needs of plants. It lacks the ability to respond to abnormal situations, such as sensor failure, network connection interruption, etc.

[0045] 4. Data transmission and storage issues: The data transmission and storage methods of existing products are not safe and reliable enough, which can easily lead to data loss or leakage. They lack the ability to analyze and process big data and cannot provide users with more valuable maintenance suggestions.

[0046] 5. System stability issues: The hardware design of existing products is not perfect and prone to failure, affecting system stability. The software design is not mature enough and prone to problems, resulting in system crashes or data loss.

[0047] Based on the above defects of the prior art, the further improvements of this case are as follows: This device is mainly aimed at mid-to-high-end flowers and plants that need special care on the market. It can automatically prevent diseases and pests of plants or flowers, automatically mix and apply fertilizers in different growth cycles, remotely monitor plant status, and remotely monitor soil data. It can ensure the growth and development of plants or flowers for a long time without supervision, and real-time data, etc. It is an indispensable part of people's fast-paced life and pursuit of home intelligence.

[0048] like Figure 1-12 As shown, the device can complete the main functions such as automatic plant watering, automatic replenishment and liquid level detection, automatic plant fertilizer ratio function, automatic fertilization function, soil self-inspection function, remote shooting, monitoring, and surveillance function, recommendation of appropriate pesticide spraying function based on local plant disease and insect pest big data, semi-automatic pesticide spraying, and some other auxiliary control functions.

[0049] This device is aimed at mid-to-high-end flowers and plants that need special care on the market. It can be used to meet the needs of modern people who are busy with life but still want to grow flowers, and the 24-hour growth detection and recording of precious plants by scientific research institutes. The product can automatically complete the prevention of diseases and pests of plants or flowers, automatic proportioning and fertilization of fertilizers in different growth cycles, remote monitoring of plant status, real-time data recording during the growth week, and remote monitoring of soil data. It can ensure the growth and development of plants or flowers for a long time without supervision, and the ability to protect and record plant growth such as real-time data. Compared with the single or simple functions of watering or supplementing light on the market, and different from the flower pots that cannot be separated from manual management, we combine multiple technologies, use the rich scalable communication interface and data processing functions of the STM32 microcontroller, and combine the Internet of Things cloud technology and big data analysis to realize the real care of flowers or plants for a long time without management. Even if there is a problem, it can be controlled remotely by humans, and truly realize the smart flower pot of unmanned operation and remote intervention.

[0050] In general, this case includes an autonomous fertilizer mixing structure, a watering system, an electronic control and Internet of Things system, and a remote monitoring and recording system for predicting and preventing pests and diseases.

[0051] Structurally: The intelligent plant care device includes a frame 3, a main water storage tank 13, a fertilizer box 2, a quantitative water storage tank 14, a fertilizer mixing chamber 22, a liquid fertilizer pool 18, an auxiliary pump 15 and a main pump 19 fixedly installed in the frame 3, and a flower pot body 5 fixedly installed beside the frame 3; A watering ring 4 is fixedly installed at the mouth of the flowerpot body 5; The top of the main water storage tank 13 is provided with a water source filling cap 1, and a reserved opening 32 for an external water pipe is opened on the side wall, and a two-position two-way solenoid valve is installed in the reserved opening 32 for an external water pipe; the quantitative water storage tank 14 is arranged beside the main water storage tank 13, and a two-position two-way solenoid valve is arranged at the connecting opening between the two; the water outlet of the quantitative water storage tank 14 is connected to the water inlet of the auxiliary pump 15 through a pipeline; the water outlet of the auxiliary pump 15 is connected to the inlet of the three-position three-way solenoid valve 16 through a pipeline, and the two outlets of the three-position three-way solenoid valve 16 are respectively connected to the fertilizer mixing chamber 22 and the liquid fertilizer tank 18 through pipelines; The fertilizer mixing chamber 22 is fixedly installed under the fertilizer box 2, and the bottom of the fertilizer mixing chamber 22 is also connected to the liquid fertilizer pool 18 through a pipeline, and a two-position two-way solenoid valve is provided in this section of the pipeline; the liquid fertilizer pool 18 is connected to the water inlet of the main pump 19 through a pipeline, and the water outlet of the main pump 19 is connected to the watering ring 4 through a pipeline.

[0052] In this way, when watering is needed, the outlet of the auxiliary pump 14 can be directly connected to the liquid fertilizer pool 18 through the three-position three-way solenoid valve 16, and finally water is supplied to the watering ring through the main pump 19; and when fertilization is needed, the outlet of the auxiliary pump 14 can be connected to the fertilizer mixing chamber 22 through the three-position three-way solenoid valve 16, so that the fertilizer is autonomously proportioned in the fertilizer mixing chamber 22 through the fertilizer autonomous proportioning structure, and water is added for stirring, and then fertilizer is provided to the liquid fertilizer pool 18 for the main pump 19 to fertilize through the watering ring.

[0053] The fertilizer box 2 has multiple parts, and the bottom of the box is a discharge port extending into the fertilizer mixing chamber 22. The discharge port is also provided with a quantitative discharge mechanism, and the multiple quantitative discharge mechanisms constitute a fertilizer autonomous proportioning structure; The quantitative discharging mechanism includes a servo 6, a cam 7, a roller 8, a strut, a strut seat, a spring 9 and a top plate 10. The middle part of the top plate 10 is rotatably connected to the discharge port of the fertilizer box 2, and one side of the top plate 10 is hinged to the top of the strut. The strut seat is fixedly installed in the frame 3, and the strut vertically penetrates the strut seat. A spring seat is also fixedly connected to the lower part of the strut. The spring 9 is pressed between the strut seat and the spring seat to keep the strut moving vertically downward. The bottom end of the strut is also movably connected to a roller 8. The cam 7 is rotatably connected to the frame 3, and the roller 8 is kept in contact with the top surface of the cam 7. The servo 6 is fixedly installed in the frame 3, and its output shaft is fixedly connected to the cam 7. After receiving the signal, the steering gear 6 drives the cam 7 to rotate. The starting position of the cam 7 should be at the maximum push position. After starting to move, the cam 7 drives the roller 8 and the support rod to move downward, and the top plate 10 at the other end of the support rod tilts downward. The fertilizer above the top plate 10 falls downward under the influence of gravity. During the rotation of the cam 7, the support rod is acted upon by the spring 9, so that the roller 8 moves close to the cam 7 until the top plate 10 returns to a horizontal state, at which time a movement cycle is completed.

[0054] The fertilizer mixing chamber 22 is also provided with a magnetic stirrer.

[0055] A check valve 17 is provided in the pipeline between the three-position three-way solenoid valve 16 and the fertilizer mixing chamber 22 .

[0056] The flower pot body 5 includes a flower planting chamber 25 and a diversion chamber 26 arranged around the flower planting chamber 25. The outer wall of the diversion chamber 26 is made of a porous material, and the inner wall is made of a waterproof material, so that the moisture in the diversion chamber can evaporate naturally. An overflow branch is provided in the pipeline between the main pump 19 and the pouring ring 4, and the overflow branch is connected to the diversion chamber 26 via the overflow valve 20; A drainage cavity 27 communicating with the flower planting chamber 25 is provided below the flower planting chamber 25 , and a capillary channel is left between the drainage cavity 27 and the flow guiding chamber 26 so that the two are kept in communication.

[0057] In this way, the problem of excessive water storage in the flower planting room can be avoided by using two overflow drainage structures, one above and one below.

[0058] About the independent fertilizer ratio structure: With reference to the operating principles of the common quantitative delivery mechanisms on the market and the quantitative proportioning mechanisms in factories, the structure is optimized and the power source is changed to a steering gear with better control accuracy to facilitate better control of the dosage of each proportion. The specific working principle is as follows: When the required fertilizer metering data and fertilization instructions are received and processed by the control board, the required type will be specified with the specific servo number, and the number of servo rotations will be determined according to the minimum ratio. After processing, the pulse signal will be sent to the corresponding aviation servo, as shown in the attached Fig.10 : As shown in the principle diagram of the proportioning structure, the servo 6 drives the cam 7 to rotate after receiving the signal. The starting position of the cam 7 should be at the maximum push position. After starting to move, the cam 7 drives the roller 8 and the support rod to move downward, and the top plate 10 at the other end of the support rod tilts downward. The fertilizer above the top plate 10 falls downward under the influence of gravity. During the rotation of the cam 7, the support rod is acted upon by the spring 9, so that the roller 8 moves close to the cam 7 until the top plate 10 returns to a horizontal state, at which time a movement cycle is completed.

[0059] The structure can autonomously proportion according to the different fertilizer requirements of plants at different stages, so as to achieve the best growth effect. The device mainly refers to the mechanism principle of the fixed proportioning device in the industrial production process and the principle of the quantitative weighing control mechanism. By considering the application scenario, the adaptation of size, the high degree of freedom of autonomous proportioning, and the complex types of proportioning, the two structures are integrated to design a suitable connecting rod structure, and the structure is miniaturized and optimized, and finally designed as a cam push rod structure. The structure occupies a small space and is powered by a servo, which is convenient for high-degree-of-freedom fertilizer proportioning. It can meet the automatic fertilization function of plants in different growth periods. The fertilization function requires the participation of a watering device, and the automatic watering device provides plants with sufficient nutrition for their growth and development through a small amount and multiple times. The functions of the autonomous fertilization proportioning structure are mainly fertilizer mixing function, automatic proportioning function, and conveying function. The good controllability of the aviation servo and the excellent power transmission and movement mode of the cam structure can achieve precise control of a small amount of fertilizer each time, and the overall error is basically within 7% (about 0.1g).

[0060] In addition, an additional small electromagnetic mixer can be used in the fertilizer area to achieve sufficient mixing of the fertilizer.

[0061] About watering system: like Fig. 9 As shown, the water source can be connected through an external water pipe 11, and enter the main water storage tank 13 through a two-position two-way solenoid valve 12, or directly injected manually through the water injection cap on the frame. Figure 2 : Schematic diagram of hydraulic pipeline, the working principle is as follows: The main water storage tank 13 has a liquid level detection system. When water flows into the main water storage tank 13 through the external water pipe 11 and does not reach the predetermined liquid level, the two-position two-way solenoid valve 12 is in the open state. After reaching the predetermined liquid level, the two-position two-way solenoid valve 12 returns to the normally closed state. At this time, the main water storage tank 13 reaches the highest water level. The main water storage tank 13 sends water to the quantitative water storage tank 14 through the second two-position two-way solenoid valve. The two-position two-way solenoid valve is a normally open valve. It becomes normally closed after the watering command is issued, and returns to normally open after the command ends. The main water storage tank 13 and the quantitative water storage tank 14 are connected in principle. Under the condition that the valve is normally open, it is guaranteed that there is always water inside. When the watering command is issued, the main water tank 13 and the quantitative water tank 14 are independent of each other, and the auxiliary pump 15 passes through a passage without any components from the three-position three-way solenoid valve 16 to the liquid fertilizer pool 18, and is sent into the watering ring through the main pump 19, that is, the flower planting room 25 in the figure. When the pressure is too high, the overflow valve 20 returns to the liquid fertilizer pool 18.

[0062] When the instruction is to apply fertilizer, after the fertilizer enters the fertilizer mixing chamber 22, the auxiliary pump 15 goes from the three-position three-way solenoid valve 16 through the check valve 17 to the fertilizer mixing chamber 22. After the electromagnetic mixer starts to work and mixes the fertilizer evenly, the two-position two-way solenoid valve changes from normally closed to open, and the mixed liquid enters the liquid fertilizer pool 18 through the liquid fertilizer guide hole 29 by gravity. At this time, the watering instruction is connected to send the diluted fertilizer into the flower planting room 25.

[0063] This structure is mainly used to complete the automatic watering function of plants, and at the same time is responsible for the dissolution, dilution, and transportation of fertilizers. Through market research and consultation with professionals in flower shops, we decided to adopt a small amount of multiple watering method. The reason why we did not adopt the current mainstream drip irrigation method in the market is that the drip irrigation method is not suitable for all plants. This product is mainly for mid-to-high-end flowers, and very few of them use hydroponics. This type of flowers pays more attention to the prevention of pests and diseases and the suitability of the growth environment. Therefore, the traditional irrigation method is adopted, and the nutrients and water content in the soil are measured to better meet the plant growth environment, timely control excessive substances and supplement missing nutrients, so that the soil will not be too dry, nor will the soil be too wet to soak the plant roots or too much fertilizer to burn the seedlings, thereby providing a better growth environment for plants. This structure can be automatically replenished after being connected to the water pipe. The built-in liquid level detection system will not allow the water source to overflow the storage tank, ensuring that the overall device can operate for a long time.

[0064] About electronic control and Internet of Things systems: The flower planting room 25 is provided with a humidity sensor for detecting the moisture content of the soil and a soil sensor for detecting the nitrogen, phosphorus and potassium content in the soil; like Fig.13As shown, it also includes an electric control and Internet of Things system, which includes a processor STM32, a processor ESP32, an online platform and a user terminal. The processor STM32 and the processor ESP32 are fixedly installed in the intelligent plant care device, the online platform is a cloud server, and the user terminal is a user's handheld device; when there are multiple intelligent plant care devices, the online platform simultaneously interacts with all the processors ESP32 for data.

[0065] The processor STM32 is simultaneously connected to a humidity sensor and a soil sensor, and is used to collect and convert data acquired by the sensors; the processor ESP32 is connected to the processor STM32, and data is exchanged with the processor STM32 through the processor ESP32, and the processor ESP32 also exchanges data with the online platform through the wifi protocol, and the user end also exchanges data with the online platform through the wireless network; the online platform processes data and sends control instructions, and the processor STM32 is also connected to the fertilizer autonomous proportioning structure and the watering system. When the processor STM32 receives the control instruction, it controls the intelligent plant care device to water or fertilize the plants.

[0066] The system mainly exchanges information, instructions and other data through the control system on the body and the communication interface extended on the control system. The sensor detects the growth environment of the flowerpot plant and observes the growth status of the plant. The soil sensor and humidity sensor collect relevant parameters, and transmit the data to the processor STM32 through the USART and IIC protocols. The data is preprocessed by the program written on the processor STM32, and then the processed data is sent to the processor ESP32 connected to the processor STM32. The processor ESP32 transmits the data to the online platform through the wifi protocol for analysis. The online platform draws the humidity change curve based on the data and records the content values ​​of nitrogen, phosphorus and potassium for the user to view and wait for the user's instructions. If the user does not issue an instruction within the specified time (such as 15-30 minutes), the online platform will autonomously process according to the preset comparison algorithm, supplement the insufficient part, and send instructions to STM32 through ESP32 to add water or fertilize. The system realizes intelligent environmental monitoring and remote control, improving user experience and management efficiency.

[0067] About the user interface: This smart flower pot application is developed using the UniApp framework and supports multi-terminal packaging for Android and iOS, ensuring a unified interface and excellent response speed. The front-end and back-end separation architecture provides a smooth user experience. In terms of security, the application uses JWT tokens for authentication and combines encrypted WebSocket to achieve real-time data transmission with the server, ensuring secure and fast data interaction. Data management is persisted through Pinia, and the data remains consistent when the user switches pages or restarts the application. The intelligent control function allows users to remotely control the functions of the flower pot, such as watering and fertilizing, through the application after completing the initial flower pot matching, meeting the user's remote management needs and greatly improving the convenience of use and intelligent experience. Includes the following functions: Cross-end support: The front-end is developed using the UniApp framework, which supports multi-end packaging such as Android and iOS. The front-end and back-end separation architecture ensures the uniformity and response speed of the interface.

[0068] Authentication and data security: JWT tokens are used to verify user identities to ensure the security of data interaction. Real-time data transmission with the server is achieved through encrypted WebSocket, allowing users to receive the latest flower pot information efficiently and quickly.

[0069] Data management: Page data is managed by Pinia to achieve data persistence and ensure that users can maintain the consistency of relevant data when switching pages or restarting the application.

[0070] Smart control function: After the user completes the initial flower pot matching, the user can remotely control the basic functions of the flower pot through the application, such as watering, fertilizing, etc. This function realizes remote control by interacting with the server, meeting the user's remote management needs for smart flower pots.

[0071] About the pest and disease prediction and prevention function: Through plant disease data images, the YOLO model is trained to achieve intelligent recognition and judgment of plant diseases. The front end uses the camera to collect video stream data, and the back end analyzes the plant disease status by processing streaming information in real time. Combined with the correlation data of the types of pests and diseases and time during the growth of a certain local flower, a prediction model for the occurrence of diseases is constructed. Through a comprehensive analysis of historical data and current environmental information, the risks of pests and diseases that the current flowers may face are inferred. When an abnormality or potential disease risk is detected, the system will push an alarm message to the front end in real time to prompt the user to take corresponding measures.

[0072] The structure of the device is an additional part. Considering the toxicity of pesticides in confined spaces, this function is designed as a modular, semi-automatic pesticide spraying function. Based on the data analysis of the common diseases of the flowers in the location of the flowers in previous years, the diseases and insect pests that may occur in this period are predicted, and the corresponding information is sent to the user through the mobile phone software. The user needs to adjust and fix the nozzle of the device according to the specific conditions of the flowers or plants raised. The water pump of the device uses a small high-pressure pump. Using jet technology, the nozzle can break the pesticide liquid to less than 50 microns to avoid pesticide residues and harm to the human body. For the safety of users, when using the spraying function, it is necessary to close the doors and windows indoors in a relatively open area. After the spraying is completed, open the windows in time for ventilation to minimize the residue of pesticides in the room.

[0073] About the remote monitoring and recording system that realizes the prediction and prevention functions of pests and diseases: The smart plant care device is also fixedly equipped with a camera located above the flower planting room 25, and the camera is connected to the processor esp32. The online platform is also provided with a YOLOv8 deep learning model for judging whether the plant state is abnormal. The smart plant care device has a plurality of fertilizer boxes 2, and one of the fertilizer boxes 2 stores pesticide powder.

[0074] The camera uploads the picture in real time via the processor esp32. The online platform uses the YOLOv8 deep learning model to analyze the health status of the plant. When an abnormal situation occurs, it is sent to the user end and waits for the user end's instructions. If the user end does not issue an instruction within the specified time (for example, 15-30 minutes), the online platform will autonomously issue a control instruction via the processor esp32 to the processor stm32, and start controlling the mixing of pesticide powder and water, and finally spraying it on the plants.

[0075] This smart flowerpot is paired with the App via Bluetooth for the first time, and can then be remotely monitored and operated through the server. The system uses multi-threading technology and uses Socket to maintain stable communication with the smart flowerpot, record activity logs and status information, and provide solid data support for monitoring and analysis. The built-in camera in the flowerpot can upload images in real time, and the server uses the YOLOv8 deep learning model to analyze the health status of the plant, automatically warn of abnormal conditions such as wilting or insect pests, and push notifications to remind users to deal with them in time. Users can intuitively view real-time monitoring images and analysis results through the app, fully understand the growth status of plants, and enjoy an intelligent management experience.

[0076] There are many specific implementation ways of the present invention. The above is only the preferred implementation mode of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements can be made without departing from the principle of the present invention. These improvements should also be regarded as the protection scope of the present invention.
