Technical Field

[0001] This invention belongs to the field of modern agricultural technology, and specifically relates to a greenhouse heating, dehumidification and sterilization system and method. Background Technology

[0002] Greenhouses provide suitable growing environments for vegetables, flowers, and trees. There are many types of greenhouses, such as glass greenhouses and plastic greenhouses. Greenhouses can enhance agricultural resilience, improve planting efficiency, and thus increase farmers' income. Currently, the application of intelligent greenhouses is becoming increasingly widespread. Intelligent greenhouses have functions such as soil temperature and humidity detection, air temperature and humidity detection, real-time image and video monitoring, automatic irrigation, automatic fertilization, and automatic pesticide spraying. However, currently, intelligent greenhouses cannot fully meet the needs of practical applications. Summary of the Invention

[0003] This application provides a greenhouse heating, dehumidification, and sterilization system and method, which can provide a more suitable environment for the growth of vegetables and other crops, and improve the management efficiency of greenhouses and the yield of vegetables and other crops.

[0004] In a first aspect, embodiments of this application provide a greenhouse heating, dehumidification, and sterilization system, comprising:

[0005] The control module is connected to a temperature sensor, a humidity sensor, a relay module, and a communication module. The relay module is connected to a heating device, an exhaust fan, and an ultraviolet lamp. The communication module is connected to a computer. The temperature and humidity sensors detect temperature and humidity and send the values ​​to the control module. The control module controls the heating device and exhaust fan based on the temperature and humidity values, and controls the ultraviolet lamp based on preset information. The control module also sends the detected environmental data to the computer via the communication module, and the computer analyzes the environmental data.

[0006] The communication module includes a communication terminal, a communication conversion module, and a WiFi module connected in sequence. The communication terminal is connected to the control module, the WiFi module is connected to the computer, and the communication conversion module is used to convert the serial port to a WiFi module interface. The communication terminal is a ZigBee terminal.

[0007] The control module is configured to: periodically compare the detected temperature value with a temperature threshold; if the detected temperature value is lower than the temperature threshold, control the heating device to heat through the relay module; if the detected temperature value is higher than the temperature threshold, control the heating device to turn off; and periodically compare the detected humidity value with a humidity threshold; if the detected humidity value is higher than the humidity threshold, control the exhaust fan to turn on through the relay module; if the detected humidity value is lower than the humidity threshold, control the exhaust fan to turn off.

[0008] It also includes a button module, through which temperature threshold, humidity threshold, and sterilization time information can be set.

[0009] The control module is an STM32 microcontroller.

[0010] It also includes an infrared sensing module, which is connected to the control module. The infrared sensing module is used to detect whether there are people in the greenhouse. If the current time is the sterilization time and there are no people in the greenhouse, the control unit controls the ultraviolet lamp to turn on through the relay module.

[0011] Secondly, this application provides a method for greenhouse heating, dehumidification, and sterilization. Using any of the above-mentioned greenhouse heating, dehumidification, and sterilization systems, the temperature sensor and humidity sensor send the detected temperature and humidity values ​​to the control module. The control module controls the heating equipment and exhaust fan according to the temperature and humidity values, and controls the ultraviolet lamp according to preset information. The control module also sends the detected environmental data to a computer, and the computer analyzes the environmental data.

It can also perform sterilization at preset times, thus better controlling the greenhouse environment, promoting the growth of vegetables, and improving greenhouse management efficiency and yield. This application can send environmental data to a computer for analysis.

[0016] The present application will be further described below with reference to the accompanying drawings and embodiments.

[0017] In the following description, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The following description provides multiple embodiments of the invention, which can be substituted or combined with each other. Therefore, this application can also be considered to include all possible combinations of the same and / or different embodiments described. Thus, if one embodiment includes features A, B, and C, and another embodiment includes features B and D, then this application should also be considered to include embodiments containing one or more other possible combinations of features A, B, C, and D, even if such embodiments are not explicitly described in the following text.

[0018] like Figure 1 As shown, the greenhouse heating, dehumidification, and sterilization system of this application includes: a control module 100, which is connected to a temperature sensor 101, a humidity sensor 103, a relay module 102, and a communication module 107. The relay module 102 is connected to a heating device 105, an exhaust fan 104, and an ultraviolet lamp 108. The communication module 107 is connected to a computer 106. The temperature sensor 101 and the humidity sensor 103 are used to detect temperature and humidity and send the temperature and humidity values ​​to the control module 100. The control module 100 controls the heating device 105 and the exhaust fan 104 according to the temperature and humidity values, and controls the ultraviolet lamp 108 according to preset information. The control module 100 also sends the detected environmental data to the computer 106 through the communication module 107, and the computer 106 analyzes the environmental data.

[0019] like Figure 2As shown, the communication module 107 includes a communication terminal 1071, a communication conversion module 1072, and a WiFi module 1073 connected in sequence. The communication terminal 1071 is connected to the control module 100, and the WiFi module 1073 is connected to the computer 106. The communication conversion module 1072 is used to convert the serial port to a WiFi module interface. The communication terminal 1071 is, for example, a ZigBee terminal. ZigBee is a wireless communication technology based on the IEEE 802.15.4 standard, mainly used for low-power, low-data-rate, and short-range wireless communication. ZigBee communication has the following characteristics: it uses radio waves in the 2.4GHz, 868MHz, or 915MHz frequency bands for communication. ZigBee networks can adopt star, mesh, or hybrid topologies. ZigBee uses low-power sleep and wake-up modes to extend device battery life. ZigBee communication adopts a layered architecture, including a physical layer, a MAC layer, a network layer, and an application layer. Each layer has different functions and responsibilities. The physical layer is responsible for the physical characteristics of wireless communication, such as modulation and demodulation, frequency selection, etc. MAC Layer: Provides data frame encapsulation and decapsulation, responsible for the reliability and security of data transmission. Network Layer: Handles routing between nodes and network topology, ensuring data transmission and reachability. Application Layer: Implements specific application functions, such as sensor data acquisition and control command transmission.

[0020] The communication conversion module 1072 is used to convert the serial port to a WiFi module interface, realizing the conversion between Zigbee communication and WiFi. The computer 106 is connected to the WiFi module, and finally the control module 100 sends the detected environmental data to the computer 106, so that the computer 106 can perform in-depth analysis of the environmental data and guide the control of the greenhouse environmental parameters in the later stage.

[0021] The control module 100 in this application is used to: periodically compare the detected temperature value with a temperature threshold. The specific value of the period can be set according to the actual application. If the detected temperature value is lower than the temperature threshold, the heating device 105 is controlled to heat through the relay module 102. If the detected temperature value is higher than the temperature threshold, the heating device 105 is controlled to turn off. The heating device 105 is, for example, a heating element. The control module 100 is also used to: periodically compare the detected humidity value with a humidity threshold. If the detected humidity value is higher than the humidity threshold, the exhaust fan 104 is controlled to turn on through the relay module 102. If the detected humidity value is lower than the humidity threshold, the exhaust fan 104 is controlled to turn off.

[0022] The control module 100 in this application is, for example, an STM32 microcontroller. The STM32 microcontroller uses an ARM Cortex processor, and its core is the data processing circuitry responsible for processing data, similar to the human brain—the data processing center. The STM32 microcontroller includes multiple I / O ports, supporting SWD and JTAG debugging. The STM32's memory includes data memory and program memory. Data memory stores data processed during program execution. Its contents can be written to or read from at any time as the program runs. Data is lost when the system loses power. This corresponds to the microcontroller's RAM (Random Access Memory), which allows random access. Program memory stores the system's application program and some unchanging data. Once written, the microcontroller can only read, not rewrite, and this data is not lost when power is off. This corresponds to the microcontroller's ROM (Read Only Memory).

[0023] The purpose of resetting an STM32 microcontroller is to restore the circuit to its initial state. There are generally three types of resets: power-on reset, system reset, and backup area reset. System reset: Except for the reset flag in the clock controller's RCC_CSR register and registers in the backup area, a system reset will reset all registers to their initial state. Power-on reset: A power-on reset will reset all registers except those in the backup area. Backup area reset: The backup area has two dedicated resets that only affect the backup area.

[0024] This greenhouse heating, dehumidification, and sterilization system also includes a button module and an infrared sensor module. Both the button module and the infrared sensor module are connected to the control module. The button module allows setting temperature thresholds, humidity thresholds, and sterilization time information. The infrared sensor module detects whether there are people in the greenhouse. If the current time is the sterilization time, the control module uses the information sent by the infrared sensor module to determine whether there are people in the greenhouse. When no one is present, the control unit uses a relay module to control the ultraviolet lamps to turn on for sterilization. The human body has a constant body temperature, generally around 37 degrees Celsius, and therefore emits infrared radiation of a specific wavelength of approximately 10µm. Passive infrared detectors work by detecting this 10µm infrared radiation emitted by the human body. The 10µm infrared radiation emitted by the human body is amplified by a Fresnel filter and focused onto the infrared sensor source. The infrared sensor source typically uses a pyroelectric element. When this element receives infrared radiation from the human body and its temperature changes, it loses its charge balance and releases a charge. Subsequent circuitry then detects and processes this charge to generate a corresponding signal.

[0025] The control module of this application can control the temperature and humidity of the greenhouse to a suitable level for the growth of vegetables and other plants. It can also perform sterilization at preset times, thus better controlling the greenhouse environment, promoting the growth of vegetables, and improving greenhouse management efficiency and yield. This application can send environmental data to a computer for analysis. The computer has stronger computing power than the control terminal, allowing for in-depth analysis of the greenhouse environmental data to guide subsequent control of greenhouse environmental parameters, providing a more suitable environment for vegetable growth.

[0026] This application also provides a method for greenhouse heating, dehumidification, and sterilization. Using any of the above-mentioned greenhouse heating, dehumidification, and sterilization systems, the temperature sensor and humidity sensor send the detected temperature and humidity values ​​to the control module. The control module controls the heating equipment and exhaust fan according to the temperature and humidity values, and controls the ultraviolet lamp according to preset information. The control module also sends the detected environmental data to the computer, and the computer analyzes the environmental data.

[0027] In this application, the embodiments of the greenhouse heating, dehumidification and sterilization method are basically similar to the embodiments of the greenhouse heating, dehumidification and sterilization system. For relevant details, please refer to the description of the greenhouse heating, dehumidification and sterilization system embodiments.

[0028] This invention also provides a computer-readable storage medium storing a computer program thereon, which, when executed by a processor, implements the steps of the above-described greenhouse heating, dehumidification, and sterilization method. The computer-readable storage medium may include, but is not limited to, any type of disk, including floppy disks, optical disks, DVDs, CD-ROMs, microdrives, as well as magneto-optical disks, ROMs, RAMs, EPROMs, EEPROMs, DRAMs, VRAMs, flash memory devices, magnetic cards or optical cards, nanosystems (including molecular memory ICs), or any type of medium or device suitable for storing instructions and / or data.
