Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, and in particular to a simulation culture device for multiple experimental treatments. Background Technology

[0002] The multi-treatment simulation culture device is an intelligent culture system that can independently or in combination regulate multiple factors such as light, temperature, humidity, gas, nutrients, pH, salinity, and drought level within the same culture platform based on real-time environmental sensor signals. This allows for the simultaneous implementation of various plant experimental treatments, including control, drought, salt stress, acid-base stress, nutrient differences, and pathogen inoculation. The device dynamically matches sensor data with preset experimental schemes through embedded control software, driving micro-pumps, micro-valves, LED light sources, semiconductor cooling chips, and other actuators to achieve precise supply and environmental simulation. Utilizing partitioned independent chambers or a rotating shared light source structure, different treatment groups can complete parallel experiments under identical external conditions. This improves the efficiency, repeatability, and realism of plant response mechanisms, stress resistance evaluation, and variety selection experiments in agricultural scientific research. It is a key dynamic simulation device for replacing traditional static culture boxes in modern plant physiology, stress biology, and breeding research.

[0003] Existing plant cultivation devices generally employ timed and quantitative irrigation or artificial watering methods. Their spraying parameters are independent of the actual soil moisture content, making it impossible to automatically adjust the water supply based on real-time feedback of soil moisture. This makes it difficult to simultaneously conduct multiple experimental treatments such as drought, salt stress, acid-base stress, and nutrient differences within the same cultivation chamber. Consequently, the microenvironment in which the plants are located deviates significantly from the dynamics of water-stress in the real field, significantly affecting the repeatability and accuracy of experimental results. Therefore, it is necessary to improve the existing devices. Utility Model Content

[0004] The purpose of this invention is to provide a simulated cultivation device for multiple experimental treatments, in order to solve the problem mentioned in the background art that existing plant cultivation devices generally adopt timed and quantitative irrigation or artificial watering methods, and their spraying parameters are independent of the actual soil moisture content, and cannot automatically adjust the water supply based on real-time feedback of soil moisture.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0006] A simulated culture device for multiple experimental treatments includes an incubator, a mounting slot is formed on the upper side wall of the incubator, a central control system is installed inside the mounting slot, and a display connected to the central control system is fixedly installed on the front side wall of the incubator. The device also includes:

[0007] The trays are fixedly installed on the inner wall of the incubator, and a slot is provided on one side wall of each tray.

[0008] A planting trough plate, wherein the planting trough plate is inserted into a slot, and a drainage hole is provided through the planting trough plate;

[0010] A humidity sensor is fixedly installed on the inner wall of the planting trough plate and connected to the central control system.

[0011] A temperature sensor is fixedly installed on the inner wall of the incubator and connected to the central control system.

[0012] A spray assembly, which is located inside the incubator, includes a pump and is connected to a central control system.

[0013] Preferably, the spraying assembly further includes three treatment liquid containers disposed on the lower side wall of the incubator. A first conduit is connected to one side of each treatment liquid container, and one end of the first conduit is connected to a pump. A second conduit is connected to one side of the pump, and one end of the second conduit is connected to a collecting pipe. A vertical pipe is connected to the outer wall of the collecting pipe, and two branch pipes are connected to one side of the vertical pipe. A first valve is provided on the branch pipe. A cavity pipe is provided above the planting trough plate, and a plurality of spray heads are connected to the lower outer wall of the cavity pipe. A flexible hose is connected to one end of each branch pipe, and one end of the flexible hose is connected to the outer wall of the cavity pipe.

[0014] Preferably, a groove rail is fixedly connected to one side wall of the incubator, and a sliding groove is opened on one side wall of the groove rail. A guide rod is slidably connected inside the sliding groove, and one end of the guide rod is fixedly connected to one end of the cavity tube.

[0015] Preferably, there are two trays, and lamp tubes are fixedly installed on the bottom wall of the uppermost tray and the top wall of the incubator. The lamp tubes are connected to the central control system.

[0016] Preferably, a camera is installed on the inner wall of the incubator, and the camera is connected to the central control system.

[0017] Preferably, it also includes a humidifier, which is disposed on one side of the outside of the incubator and has a humidification pipe connected to one side thereon.

[0018] Preferably, the bottom walls of the three treatment liquid containers are all connected to a first row of pipes, the bottom wall of the tray plate is connected to a second row of pipes, one end of the first row of pipes is connected to a waste liquid discharge pipe, the lower end of the second row of pipes is connected to the outer wall of the waste liquid discharge pipe, the first row of pipes is provided with a second valve, and the waste liquid discharge pipe is provided with a third valve.

This achieves a closed-loop "humidity-drive" water replenishment system, avoiding over-drying or over-wetting caused by timed irrigation. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example:

[0030] Please see Figures 1-5 As shown, this utility model is a simulated culture device for multiple experimental treatments, including...

[0031] Incubator 1, wherein a mounting slot is provided on one side wall of the upper part of incubator 1, and a central control system is installed inside the mounting slot; a display 2 connected to the central control system is fixedly installed on the front side wall of incubator 1; and further comprising:

[0032] The tray plate 3, a plurality of the tray plates 3 are fixedly installed on the inner wall of the incubator 1, and a slot is provided on one side wall of the tray plate 3;

[0033] Planting trough plate 4, which is inserted into the slot opening and has a seepage hole 5 through it;

[0034] Partition 6, several partitions 6 are fixedly disposed on the inner wall of the planting trough plate 4;

[0035] Humidity sensor 7 is fixedly installed on the inner wall of the planting trough plate 4 and connected to the central control system;

[0036] Temperature sensor 8 is fixedly installed on the inner wall of incubator 1 and connected to the central control system;

[0037] A spray assembly is disposed inside the incubator 1, and includes a pump 9, which is connected to a central control system.

[0038] The central control system utilizes existing technology. Specifically, it adopts the widely commercially available architecture of "STM32F4 series ARM Cortex-M4 microcontroller + RS-485 / CAN bus + touchscreen host computer": It uses the STM32F407VGT6 as the main control chip, with a built-in 168MHz main frequency, 1MB Flash, and 192KB RAM. It acquires analog signals from the humidity sensor 7 and temperature sensor 8 via an on-chip 12-bit ADC, and utilizes hardware I / O... 2 The STM32's C interface connects to an SHT35 high-precision digital temperature and humidity probe for redundancy verification. The chip's GPIO port drives a relay module via a ULN2803 Darlington array to control the start / stop and direction of pump 9, first valve 16, second valve 29, and third valve 30. Simultaneously, PWM output adjusts the brightness of lamp 22 (0-100%) and the atomization amount of humidifier 24, achieving closed-loop control of light, temperature, humidity, and liquid. For communication, the STM32's USART port connects to a MAX3485 chip to form an RS-485 bus, enabling bidirectional communication with display 2 (TJC8048T070_011CHMI serial screen) to display parameters of each partition area in real time and support touch-based modification of settings. Furthermore, the chip's SDIO interface connects to a Micro-SD card to periodically store sensor data and JPEG images captured by camera 23 according to the FATFS file system, facilitating subsequent export for stress response analysis. The entire control logic is based on Keil. The FreeRTOS multitasking firmware developed by MDK has task cycles of 10ms for sensor sampling, 100ms for valve control, and 500ms for screen refresh, ensuring millisecond-level response even when multiple test areas are running in parallel. All of the above hardware and software modules are existing mature solutions, and the automatic monitoring, multi-liquid switching, and precise spraying functions required by this utility model can be achieved without additional creative design.

[0039] As can be seen from the above, the humidity sensor 7 detects the moisture content of the soil area enclosed by each partition 6 in real time and feeds the signal back to the central control system. When the humidity of the area is lower than the set threshold, the system automatically starts the pump 9 to draw liquid from the corresponding treatment liquid container 10, and then through the first conduit 11 → second conduit 12 → collection pipe 13 → vertical pipe 14 → branch pipe 15 → hose 19 → cavity pipe 17, and finally sprays it precisely to the area by the spray head 18, realizing the "humidity-drive" closed-loop water replenishment and avoiding over-drying or over-wetting caused by timed watering.

[0040] Depend on Figure 3 and Figure 5It is understood that the spraying assembly also includes three treatment liquid containers 10 disposed on the lower side wall of the incubator 1. A first conduit 11 is connected to one side of each treatment liquid container 10. One end of the first conduit 11 is connected to a pump 9. A second conduit 12 is connected to one side of the pump 9. One end of the second conduit 12 is connected to a collecting pipe 13. A vertical pipe 14 is connected to the outer wall of the collecting pipe 13. Two branch pipes 15 are connected to one side of the vertical pipe 14. A first valve 16 is provided on the branch pipe 15. A cavity pipe 17 is provided above the planting trough plate 4. Several spray heads 18 are connected to the lower outer wall of the cavity pipe 17. A flexible hose 19 is connected to one end of each branch pipe 15. One end of the flexible hose 19 is connected to the outer wall of the cavity pipe 17.

[0041] As can be seen from the above, the first valve 16 installed on the branch pipe 15 is independently opened and closed by the central control system, which can supply clean water, salt solution, acid solution or nutrient solution to the corresponding area, so that multiple experimental treatments such as drought, salt stress, acid and alkali stress and nutrient difference can be completed simultaneously in the same incubator 1 without affecting each other, thereby improving experimental efficiency and comparison accuracy.

[0042] Depend on Figure 5 It is known that, in order to facilitate the adjustment of the position of the spray head 18, a groove rail 20 is fixedly connected to one side wall of the incubator 1. A sliding groove is opened on one side wall of the groove rail 20. A guide rod 21 is slidably connected inside the sliding groove. One end of the guide rod 21 is fixedly connected to one end of the cavity tube 17.

[0043] As can be seen from the above, the guide rod 21 slides along the groove rail 20, which can adjust the horizontal position of the cavity tube 17 so that the spray head 18 is always directly above the target area, ensuring that the liquid falls evenly on the soil surface and improving the uniformity of treatment.

[0044] Depend on Figure 3 It is known that there are two tray plates 3. The bottom wall of the uppermost tray plate 3 and the top wall of the incubator 1 are both fixedly installed with lamp tubes 22, and the lamp tubes 22 are connected to the central control system.

[0045] As can be seen from the above, the lamp tube 22 is dimmed by the central control system. The light cycle and light intensity can be set according to the test plan. In conjunction with the humidity and temperature sensors 8, it realizes the linkage of multiple factors such as light, temperature and water, simulates the natural day and night changes, and enhances the realism of the test environment.

[0046] Depend on Figure 3 It is known that a camera 23 is installed on the inner wall of the incubator 1, and the camera 23 is connected to the central control system.

[0047] As can be seen from the above, camera 23 takes pictures of the plant phenotype at regular intervals, and the images are transmitted back to the central control system for analysis of leaf color, plant height, and degree of wilting. The images are then correlated with humidity and temperature data to achieve a visualized and quantitative assessment of stress response, reducing errors from manual observation.

[0048] Depend on Figure 2 It is known that the incubator also includes a humidifier 24, which is located on one side of the outside of the incubator 1 and has a humidification pipe 25 connected to one side. One end of the humidification pipe 25 passes through the side wall of the incubator 1 and extends to the inside of the incubator 1.

[0049] As can be seen from the above, the humidifier 24 replenishes water vapor into the chamber through the humidification pipe 25. The central control system automatically starts and stops based on the coupling data of the temperature sensor 8 and the humidity sensor 7 to prevent the soil from losing water rapidly due to high temperature and low humidity, maintain stable relative humidity, and ensure the continuity and repeatability of the stress test.

[0050] Depend on Figures 2-3 It is known that the bottom walls of the three treatment liquid containers 10 are all connected to the first row of pipes 26, the bottom wall of the tray plate 3 is connected to the second row of pipes 27, one end of the first row of pipes 26 is connected to the waste liquid discharge pipe 28, the lower end of the second row of pipes 27 is connected to the outer wall of the waste liquid discharge pipe 28, the first row of pipes 26 is provided with a second valve 29, and the waste liquid discharge pipe 28 is provided with a third valve 30.

[0051] As can be seen from the above, the first row of pipes 26 and the second row of pipes 27 both converge into the waste liquid discharge pipe 28. After the test, the central control system opens the second valve 29 and the third valve 30 in sequence, which can discharge the residual liquid in each treatment liquid container 10 and the tray plate 3. The residual liquid in the tray plate 3 seeps out through the seepage hole 5 to avoid the accumulation of treatment liquid, and at the same time facilitates cleaning and quick switching to the next cycle test.

[0052] Depend on Figure 1 It is known that the top of each of the three processing liquid containers 10 is connected to an inlet pipe 31, and the upper end of the inlet pipe 31 is connected to an inlet funnel 32.

[0053] As can be seen from the above, personnel can replenish the liquid inside the treatment liquid container 10 through the liquid inlet funnel 32 and liquid inlet pipe 31.

Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.

[0055] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
