The carbon dioxide sensor 503 and the temperature and humidity sensor 506 are arranged in the transparent cover 4, and the side wall of the transparent cover 4 has a ventilation hole 401; it also includes: a ventilation fan 7, which is arranged on the transparent cover 4 and opposite to the ventilation hole 401, and the central console 6 is used to control the ventilation fan 7. The light sensor 504 is arranged in the transparent cover 4; it also includes: a fill light 8, which is arranged in the transparent cover 4, and the central console 6 is used to control the fill light 8. The detection ends of the pH sensor 501, the conductivity sensor 502 and the water turbidity sensor 505 are all used to extend into the nutrient solution; it also includes: a liquid inlet pipe 9, which is arranged at one end of the base container 1 and is connected to the culture chamber 101; a water pump, the liquid outlet of the water pump is connected to the liquid inlet pipe 9, and the liquid extraction end of the water pump is connected to the external nutrient solution source; an air inlet pipe 11, which is arranged at the other end of the base container 1 and is connected to the culture chamber 101; an air supply pump, the air supply end of the air supply pump is connected to the air inlet pipe 11; a stirrer 12, which is arranged in the base container 1 and is used to stir the nutrient solution in the culture chamber 101; wherein the central console 6 is used to control the water pump, the air supply pump and the stirrer 12. It also includes: a heating plate 13, which is arranged in the transparent cover 4, and the central console 6 is used to control the heating plate 13. The core control unit of the central console 6 is an STM32F103C8T6 microcontroller, and a serial port screen 601 is provided on the outside of the central console 6. The center console 6 has an Internet of Things communication module ESP-12F for exchanging data with a cloud server.

[0047] During use, the base container 1 and the transparent cover 4 form a relatively airtight independent space, and the internal environment is easy to regulate. The detection device 5 is used to monitor and collect the parameters of the internal plant growth environment, and the central control console 6 performs data analysis and recording, etc. The drainage groove 202 communicates with the counterbore 201. The upper side of the culture barrel 3 has a notch 302, and the notch 302 communicates with the drainage groove 202 to achieve a better reflux effect. The drainage groove 202 can be in a "丰" - shaped structure, having several branch structures communicating with each counterbore 201. The counterbores 201 can be arranged in two rows at intervals in an array. The upper side of the culture barrel 3 is a convex edge structure, which can be lapped in the counterbore 201 to achieve height - direction support and positioning. The through - holes 301 on the side wall enable the plant roots to contact the nutrient solution.

[0048] The detection device 5 is the sensor acquisition part. The carbon dioxide sensor 503 and the temperature - humidity sensor 506 can be arranged inside the transparent cover 4 to monitor the environment inside the transparent cover 4. Then the central control console 6 can control the ventilation fan 7 to start to promote the air circulation inside the transparent cover 4 to change the carbon dioxide concentration and reduce the temperature. When the humidity is high, it can also be exhausted through the ventilation fan 7 to reduce the humidity. The ventilation fans 7 can be arranged on both the left and right sides of the transparent cover 4. The ventilation fans 7 on the left and right sides can be cooperatively arranged. The ventilation fan 7 on the left supplies air into the transparent cover 4, and the ventilation fan 7 on the right exhausts air outwards to better form air circulation. The carbon dioxide sensor 503 can use the MG - 812 sensor to monitor the change of CO2 concentration in the greenhouse, and is less affected by the change of temperature and humidity. The temperature - humidity sensor 506 can use the AM2301 temperature - humidity sensor 506. The temperature resolution of this sensor is 0.1 °C, the temperature measurement range is from - 40 °C to 80 °C, the humidity resolution is 0.1%RH, and the humidity measurement range is from 0%RH to 99.9%RH. In addition, the accuracy of the AM2301 sensor is temperature ±0.5 °C, humidity ±3%RH, meeting the monitoring requirements of the system. It has an ultra - small volume, extremely low power consumption, and can perform long - distance transmission, which enables the transformation of the circuit according to the needs of the system in the later stage.

[0049] The light sensor 504 can detect the internal light parameters. When the light is insufficient, the central control console 6 can control the supplementary light 8 to be turned on to supplement the light and promote plant growth. When the light is too strong for some plants, it can be manually moved away from the light position for adjustment. The light sensor 504 can adopt the ambient light sensor 504 based on TEMT6000. It is very sensitive to visible light. Just like the human eye, it can easily capture the change of tiny light, and has a peak sensitivity at 570 nanometers. The main control unit A / D channel is connected to the analog end for acquisition, without the need for an external filter and has a good linear output.

[0050] The pH sensor 501 can detect the pH value of the nutrient solution so as to replace the nutrient solution in time and ensure the normal metabolism of the plant. The pH sensor 501 can adopt the E-201 pH sensor 501 because it has the advantages of simple calibration, low power consumption, low cost, easy to carry and long-term uninterrupted monitoring.

[0051] Conductivity is a measure of the concentration and type of dissolved substances in water, and can reflect important information such as the content and chemical properties of nutrients in water. The conductivity sensor 502 can detect the total dissolved solid content in water. The central console 6 determines whether the nutrient solution needs to be replaced based on the current turbidity. A TDS conductivity sensor 502 can be used.

[0052] The pH sensor 501 and the conductivity sensor 502 can be arranged in the base container 1 or in the transparent cover 4 , and their detection ends can be extended into the nutrient solution in the culture chamber 101 .

[0053] The turbidity of the nutrient solution is very important for plant growth, because high turbidity will cause the plants to not absorb enough nutrients. Therefore, the use of a turbidity sensor can help the system automatically monitor the turbidity of the nutrient solution so as to adjust the cleanliness of the nutrient solution in time to ensure the normal growth of the plants. The sealed turbidity sensor can be set at the bottom of the culture chamber 101 to detect the bottom environment. The TWS-30 turbidity sensor can be used to obtain the turbidity parameters of the nutrient solution so as to replace the nutrient solution in time.

[0054] When replenishing the nutrient solution, the water pump pumps the external nutrient solution into the culture chamber 101 through the liquid inlet pipe 9 for replenishment. When the nutrient solution needs to be replaced, two methods can be used. The first method is to replenish the nutrient solution through the water pump to gradually mix and partially replace the old nutrient solution. The old nutrient solution needs to be discharged to the outside, and the liquid outlet pipe 10 can be set on the side wall of the base container 1 to facilitate the discharge of the old nutrient solution; the second method is to set the liquid outlet pipe 10 on the side of the base container 1, and add a liquid pump, first use the liquid pump to extract the old nutrient solution inside, and then the water pump replenishes the new nutrient solution. The discharged old nutrient solution can also be collected and processed. When the water pump is replenishing the liquid, the interval liquid supply method can be used to help increase the oxygen content in the nutrient solution. The air supply pump can supply oxygen or air into the culture chamber 101, and the stirrer 12 can stir the solution in the culture chamber 101 to avoid precipitation causing uneven solution and waste of nutrients. The stirrer 12 can be installed in the culture chamber 101 in a waterproof and sealed manner.

[0055] The air pump, water pump and liquid pump are all existing components, as part of the compensation system, to adjust the internal environment, which can be realized by those skilled in the art, and are not shown in the figure, and can be integrated and arranged outside the base container 1. The new nutrient solution outside can be stored in the bottle body and connected to the liquid extraction end of the water pump.

[0056] The heating plate 13 can be a ceramic heating plate 13. When the temperature inside the transparent cover 4 is low, the heating can be turned on to increase the temperature.

[0057] The center console 6 uses the STM32F103C8T6 microcontroller, which is based on the ARM Cortex-M3 core. As the main control unit, it not only takes into account the balance between performance and power consumption, but also has rich functions: it has 64KB of Flash memory on the chip, 37 available GPIO ports, and is connected to two APB buses, including 20KB of SRAM, and has 2 12-bit ADC collectors to meet the requirements for collecting voltages of multiple sensors. The 3 serial communication interfaces can be connected to a variety of devices. Its internal integrated A / D conversion circuit can reduce the use of additional A / D conversion modules, which not only reduces the hardware area but also reduces the cost of hardware use. In addition, two optional I2C interfaces and SPI interfaces are provided, which can not only meet the system's needs for using multiple sensors but also facilitate subsequent upgrades of the system (for example: adding wind speed sensors, GPS positioning, and installing solar panels). Its high performance and low power consumption can meet the real-time processing needs of various data in the greenhouse and nutrient solution. Its powerful functions have laid the foundation for the realization of this project and reduced the overall cost of the system.

[0058] The serial port screen 601 can display and operate data monitoring and control. The TJC4832T135_011 serial port screen 601 screen is a resistive touch screen that meets the display requirements of the system and can meet the use of most scenarios. The normal working voltage range is 4.5-6.0V and the working temperature range is -20~70℃. It has 8M Flash storage and 3584bytes SRAM, 1k serial port instruction cache, built-in high-speed digital chip, and developed using standardized instruction sets. Use UART HMI to configure the interface, write relevant logic, and then compile. Burn the program to the serial port screen 601 to run the corresponding control display program normally. The serial port has communication function and is connected to the main control unit through the UART serial port. It can display various parameters in the current greenhouse and nutrient solution, and can modify various parameters. At the same time, it can also control the operation of its compensation system, such as replenishing nutrient solution and ventilation.

[0059] The IoT communication module ESP-12F used in the system has good performance, power consumption, stability and other aspects. It is connected to the main control unit through a serial port. As part of the wireless communication module, it enables the system to exchange data with the cloud server, realize remote control communication, and facilitate data display and regulation on the mobile phone through the corresponding APP, thereby improving user participation and making it more intelligent and convenient.

[0060] An ultrasonic sensor or a water level sensor may also be added to communicate with the central console 6 to detect the water level of the nutrient solution, to prevent the nutrient solution from being too low, and to automatically start the water pump through the central console 6 in time to replenish the solution.

[0061] Furthermore, it also includes: an installation frame 14, which is arranged at the upper end of the base container 1, the middle part of the installation frame 14 has an opening, the support plate 2 is overlapped at the middle part of the installation frame 14, the support plate 2 is arranged on the base container 1 through the installation frame 14, the upper end of the installation frame 14 has a plug-in groove 1401 along the ring, the transparent cover 4 is plugged into the plug-in groove 1401, and the transparent cover 4 is arranged at the upper end of the base container 1 through the installation frame 14.

[0062] When in use, the base container 1 and the transparent cover 4 are connected through the middle installation frame 14, which is convenient and quick to install up and down, and also convenient to install the support plate 2. The transparent cover 4 is plugged into the installation frame 14, which is convenient for disassembly and assembly, and can conveniently perform operations such as replacement and picking of internal plants.
