Description

Technical Field

[0001] The invention belongs to the technical field of intelligent potted plants, and in particular relates to an intelligent potted plant monitoring and supply system. Background Art

[0002] Some potted plants need to be planted at home or in the office area. Green plants can make people pleasing to the eye, cultivate sentiment, and purify the soul. Green plants need to be cared for, but due to the fast-paced life, people sometimes find it difficult to squeeze out time to take care of their beloved green plants, which causes the green plants in the home or office area to grow unhealthy. When the light and watering do not meet the requirements, the green plants will wither and die, and the survival rate of the green plants will be reduced.

[0003] Most of the protection of green plants starts from three aspects: light, temperature, and soil moisture. These three aspects greatly affect the normal growth of plants. At present, most of the flower pot products on the market do not have relevant operation designs for potted plants in the sun. The range and angle of light exposure for green plants are fixed, which may cause the leaves of plants in the sun to be lush on one side and sparse on the other. This is not conducive to the use of light energy by plants and affects their appearance. Although some patent documents have flower pots that achieve uniform light exposure, there is no reasonable coordination between the light level and the moisture content of the soil. They all operate independently. Under light conditions, it is determined that the plant loses moisture quickly, so water is replenished, but the soil humidity is not taken into account. The humidity is how long the plant can maintain water replenishment, etc. Water replenishment needs to be considered based on multiple factors to be beneficial to the growth of green plants, and there are no relevant records in existing patent documents or journals. Summary of the invention

[0004] The purpose of the present invention is to design an intelligent potted plant monitoring and supply system that can play a role in the maintenance of potted plants, involving the degree of light and the degree of temperature and humidity to ensure the normal growth of the plants.

[0026] The following are examples and attached Figure 1-7 The present invention is further described as follows:

[0027] Example: Figure 1-7As shown, an intelligent potted plant monitoring and supply system includes a flower pot holder 1, a cover plate 2, a light intensity sensor 3, a thrust ball bearing 4, an angular contact ball bearing 5, a slot sleeve 6, a sleeve 7, a transmission gear 8, a special shaft 9, a stepper motor 10, a water supply mechanism 11, a soil moisture sensor 12, an integrated circuit board 13, a water pipe support rod 14, a display part 15, a bearing part 16, a tray 17, a coarse filter layer 20, a WiFi module 18, a threshold modification button group 19 and a temperature sensor 21.

[0028] The system is composed of a container shell composed of a tray 17, a bearing part 16 and a cover plate 2, wherein the tray 17 has a square protrusion, and the corresponding system bearing part 16 has a square depression. The two are detachable through this combination. The detachable nature of the tray and the use of transparent materials make the tray dual-purpose as a tray and a water tank. The cover plate 2 is installed on the bearing part 16 to form a relatively closed space to reduce the influence of foreign matter from the outside; the light intensity sensor 3 is installed on the cover plate 2 to contact the light environment similar to that of the potted plants, and the probe of the soil moisture sensor 12 is installed in the potted soil and connected to the integrated circuit board through the hole of the cover plate 2 through the wire. A support is installed in the bearing part. The support is ring-shaped, and the inner and outer rings are provided with protrusions. The thrust ball bearing is embedded between the inner and outer ring protrusions. The height of the protrusion is 2mm, which is used to clamp the thrust ball bearing to prevent the bearing from moving in the left and right directions. A hollow cylinder is provided below the support to bear the upper part, making the overall structure more stable and minimizing the fracture of the weak part at the bottom of the upper part.

[0029] A flower pot holder 1 is installed in the hole of the cover plate 2. The bottom of the flower pot holder 1 is provided with a gear and a rotating shaft. A thrust ball bearing 4, an angular contact ball bearing 5, a slot shaft sleeve 6 and a shaft sleeve 7 are installed one by one on the rotating shaft from top to bottom. A pair of properly mounted angular contact ball bearings and a plane thrust ball bearing constitute a flower pot holder supporting mechanism to assist in completing the operation of the transmission mechanism. The gear is meshed with the transmission gear 8. The transmission gear 8 is installed on the output shaft of the stepper motor 10. A water supply mechanism 11 is installed in the tray 17. A light intensity sensor 3 is installed on the tray 17. A temperature sensor 2 is installed on the bearing part 16. 1 and a display part 15, a soil moisture sensor 12 collects soil moisture data of potted plants, an integrated circuit board is installed in a bearing part 16, a single-chip computer 24, a threshold value modification button group 19 and a WiFi module 18 are arranged on the integrated circuit board 13, data obtained by the light intensity sensor 3, the temperature sensor 21 and the soil moisture sensor 12 are input into the single-chip computer 24, the single-chip computer 24 displays information through the display part, the single-chip computer 24 controls the operation of the water supply mechanism 11 through the relay module, and the single-chip computer 24 controls the operation of the stepper motor through the stepper motor driver.

[0030] Figure 2As shown, the display part 15 specifically adopts a 1.8-inch display screen. The upper half of the display content is three real-time parameters: light intensity, soil moisture and temperature, and the lower half corresponds to the upper and lower thresholds of the three parameters, so as to more intuitively understand the environmental conditions and preset environmental conditions of the plants. Water supply mechanism 11 ( Figure 7 As shown in the figure, it is composed of a water pump, a water pipe and a water flow control valve 25. The water pipe support rod 14 is installed through the holes reserved in the cover plate and the system bearing part. Raising the water pipe can prevent the watering system from being affected by the pot rotation function. The water pipe 11 is installed in the groove above the water pipe support rod 14.

[0031] The outer surface of the bearing part 16 can be designed with various patterns, and the traditional Chinese decorative patterns such as the circular pattern and the gluttonous pattern can be introduced into the appearance design to enrich the connotation. The traditional Chinese culture is organically unified and closely combined with the actual situation, so as to make use of the past for the present, bring forth the new through the old, and realize the organic connection between tradition and modernity.

[0032] Figure 1 and 3 As shown, the stepper motor 10, the transmission gear 8, the special shaft 9, and the flower pot holder 1 constitute a transmission mechanism. The stepper motor 10 is fixed to the system bearing part 16 by screws, and the transmission gear 8 is installed on the special shaft 9. The special shaft 9 is specifically a square shaft. The special shaft 9 is installed on the shaft of the stepper motor 10. The square special shaft 10 can limit the axial position of the transmission gear 8 in the direction of the motor shaft. The bottom of the flower pot holder 1 is designed with a gear to avoid the cumbersome installation of too many parts. The flower pot holder 1 is installed on the system bearing part through the thrust ball bearing 4 and the angular contact ball bearing 5, and meshes with the transmission gear 8. The angular contact ball bearing 5 is axially fixed to the system bearing part 16 through the slotted sleeve 6 and the sleeve 7, making the transmission system more stable and more reliable.

[0033] The water supply mechanism 11 can be placed in the tray 17, and the water in the tray is used to water the plants; a coarse filter layer 20 is installed on the upper center part of the flower pot tray 1. The coarse filter layer 20 is composed of two layers of circular mesh steel mesh and a middle layer of filter cotton. It can filter out coarse particles in the water flow to avoid clogging the water pump when the water is reused. Excess water from watering falls into the tray 17 through the coarse filter layer 20 installed on the flower pot tray 1 and is pumped out again by the water pump. This cycle is repeated to achieve the effect of water recycling, and under the same water capacity, the soil moisture of green plants can be maintained healthy for a longer time than an independent water tank.

[0034] In order to allow the drained water after watering to quickly flow into the tray 17 , a certain slope is designed on the side of the flower pot holder 1 where the potted plant is placed, with the outer side being higher and the middle being lower, so that the drained water flows converge at the center and leak down into the tray 17 .

[0035] Figure 5As shown, the WiFi module 18 uploads local data to the Internet of Things, so that remote monitoring and control can be achieved. The soil moisture sensor module is used to collect soil moisture data for potted plants. If the current soil moisture is lower than the lower limit, the water pump is started for watering until the soil moisture reaches or exceeds the upper limit, and the watering operation stops, and so on. The illumination module is used to collect the illumination data of the environment in which the potted plants are located. If the current illumination is between the lower limit and the upper limit, the system determines that the illumination is suitable, and the pot is rotated 180° and rotated once every 30 minutes, alternating between forward and reverse rotation; if the illumination conditions are not suitable after 30 minutes, the pot will not be rotated again, and the pot rotation function is completed by the transmission mechanism; if the current illumination is lower than the lower limit or higher than the upper limit, it is determined that the illumination conditions are not suitable. At this time, the smart home under the same network is linked, such as smart curtains or smart lighting control for shading or supplementary lighting; the supplementary lighting operation needs to consider whether the current time period is suitable. The temperature sensor module is used to collect the temperature data of the environment in which the potted plants are located. If the current temperature is lower than 7°C or higher than 40°C, the smart home under the same network, such as air conditioning or smart curtains, is linked to control the temperature.

[0036] The relay module 22 and the stepper motor driver TB6600 are installed in the system bearing part 16, connected to the integrated circuit board 13 through wires to ensure the integrity of the overall system, and the power line is led out through the reserved hole of the system bearing part 16; the single chip computer 24, the threshold modification button group 19 and the WiFi module 18 are installed on the integrated circuit board 13. The threshold modification button group 19 is used to modify the upper and lower thresholds of the three parameters of soil moisture, light intensity and temperature through different combinations, so that the system is adapted to various plants and can plan a suitable growth environment for various plants.

[0037] Figure 6 As shown, considering that the water flow rate has an impact on the soil erosion rate, a water flow control valve 25 is added to the water supply mechanism 11 to control the water flow rate and avoid the situation where the plant roots and fertilizers are exposed due to excessive water flow.

[0038] Figure 7 As shown, the water pipe support rod 14 is further increased with a water pipe support extension rod 26. By combining and installing a plurality of water pipe support extension rods 26 with the water pipe support rod, the water pipe can be raised to a suitable height to accommodate different potted plants.

[0039] Figure 8 As shown, based on the acquired cloud data, the user terminal application will display 8 corresponding expressions to the user so that the user can intuitively know the current plant status. The 8 expressions display information through the display part.

[0040] In the above embodiment: the single chip microcomputer adopts a microcontroller of the STM32F103C8T6 model, the WiFi module adopts an ESP-01S WiFi module, the light sensor adopts a GY-302 digital light sensor illumination module, and the stepper motor driver 23 adopts a stepper motor driver of the TB6600 model.

[0041] Specific working principle:

[0042] When using, place the potted plant on the flower pot holder, and under the combination of the water pipe support rod and the extension rod, raise the water pipe to a suitable height. Turn on the power, press the power switch and the whole system starts. The three sensor modules detect the light, soil moisture and temperature of the current plant environment, and upload the information to the single-chip microcomputer. The single-chip microcomputer determines whether to perform local watering and pot rotation according to the set relevant thresholds, or the IoT operation links the smart home through the developed IoT products to compensate for environmental needs; the set threshold can be changed according to the needs of the current potted plants, and the change method is the threshold modification button group on the integrated circuit board. The sensor-related real-time data and threshold data are displayed on the display screen. During the watering operation, the water flow control valve is adjusted to control the water flow rate. When the current soil moisture is lower than the set lower limit threshold, the single-chip microcomputer controls the water pump to water, and the watering stops when the soil moisture rises to or exceeds the upper limit threshold. When the current light intensity meets the light conditions (that is, when the current light intensity is between the upper and lower thresholds), the pot is rotated every 30 minutes to maintain the plant morphology of the potted plant; if the light conditions are not met after 30 minutes, the pot will not be rotated. If the current light condition is lower than the lower limit or higher than the upper limit, the system determines that the light condition is not suitable. Through the Internet of Things products, the smart home in the same network is linked, such as smart curtains or smart lighting control to block light or fill light; the fill light operation needs to consider whether the current time period is suitable, such as poor light conditions at night but no fill light. When the current temperature is lower than 7℃ or higher than 40℃, the smart home in the same network is linked, such as air conditioning or smart curtains for temperature control. The relevant functions and structural designs can well maintain the normal growth of plants, enable plants to make full use of sunlight and maintain good plant morphology, and save water resources.

[0043] Based on the above implementation, the status of the flower pot can be displayed according to the display part on the device, and the status is specifically displayed through 8 expressions. Figure 8 As shown, the 8 expressions represent watering, too much sun, too dark, overheating, normal state, drought, potting, and too cold. The state of the potted plant can be judged by observing the expressions on the display.

[0044] The above are all preferred embodiments of the present invention. For ordinary technicians in this technical field, without departing from the principle of the present invention, various equivalent modifications to the present invention belong to the protection scope of the claims attached to this application.
