As an important device for adjusting the ventilation and temperature of greenhouses, the intelligent and convenient control method of the rolling film machine directly affects the control effect and management efficiency of the greenhouse environment. At present, there are many problems with the traditional control method of the rolling film machine.

For example, a Chinese patent document discloses an agricultural greenhouse environment management and monitoring device based on the Internet of Things [201821867512.8], in which its PLC controller is connected to a detection input component and an output execution component. In the detection input component, a temperature and humidity sensor, an illuminance sensor, a stem growth change sensor, and a fruit swelling sensor are connected to the PLC controller. The temperature and humidity sensor is used to monitor the temperature and humidity data information of the air environment inside the agricultural greenhouse; the illuminance sensor is used to monitor the light data information of the environment inside the agricultural greenhouse; the stem growth change sensor is used to monitor the stem growth change data information of the plants inside the agricultural greenhouse; the fruit swelling sensor is used to monitor the fruit swelling data information of the plants inside the agricultural greenhouse; in the output execution component, a circulation fan, a window opening motor, an electric rolling film machine, an irrigation device, a hot air blower, and a supplementary light are respectively connected to the PLC controller through relays.

Detailed implementation manners

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0028] As Figure 1-8 shown, a digital remote control system for a rolling film machine based on an intelligent controller includes an independent greenhouse 1 equipped with a rolling film machine. The independent greenhouse 1 is connected to the cloud platform 3 through the Internet of Things 2. The cloud platform 3 has an AI large model layer 31, a digital twin 32, and a cloud storage layer 33. Among them, the digital twin 32 also depends on the sensing data collection of the independent greenhouse 1 and the data transmission of the Internet of Things 2. Among them, the AI large model layer 31 performs data cleaning and feature extraction, and finally displays the digital display of the overall greenhouse.

[0029] Specifically, the independent greenhouse 1 is internally equipped with a drive module 4 connected to a rolling film machine, and a sensing module 5. The drive module 4 and the sensing module 5 are connected to the Internet of Things 2 through a transmission module 6. The transmission module 6 includes an inter-shed terminal controller 61, which is connected to a relay device 62 and a switching device 63. The switching device 63 is connected to a wireless access device 64. The inter-shed terminal controller 61 controls the forward and reverse rotation of the electrodes of the rolling film machine through the drive module 4. The internal encoder can control the rotation steps of the rolling film machine and will automatically stop when encountering resistance, effectively protecting the equipment and improving the control accuracy. The rotation of the motor is controlled by digital means to ensure stable and reliable signal transmission.

[0030] The sensing module 5 is composed of various sensors, such as air temperature and humidity sensors, soil temperature and humidity sensors, pest monitoring sensors, light meters, etc. The drive module 4 is composed of various power equipment, such as water pumps, motors, lights, valves, gates, etc. The transmission module 6 conducts data transmission on-site in wired and wireless ways, such as wired RS485 communication, CAN communication, etc.

[0031] After collecting local data information, the Internet of Things 2 transmits data information, including instructions, data, graphics, voiceprints, videos, etc., to the Internet through the relay device 62 and the switching device 63 according to pre-settings. The cloud platform 3 uses AI artificial intelligence agents (LLMAgents) such as Ollama, LangChain, and pytorch frameworks, and builds a knowledge graph for local deployment in the agricultural field by Llama + Qwen + RAG + NL2SQL. Combining with existing agricultural knowledge bases, it identifies cutting-edge technologies such as ASR + TTS + NLP to realize AI intelligent data analysis application scenarios. At the same time, it uses the OpenCV deep machine vision algorithm to realize application scenarios such as image, audio and video CV multi-modal industrial object detection and data annotation.

[0032] Among them, the cloud platform 3 uses the server as the carrier and LOT as the platform to classify, label, and store the huge amount of various data collected, and re-organize the data through the digital planning model to provide the following steps for artificial intelligence calculation in a quantitative manner:

[0033] S1: Data cleaning: Preprocess the data uploaded by the sensors, including removing outliers and filling in missing values;

[0034] S2: Feature extraction: Extract features from the cleaned data that are helpful for model learning;

[0035] S3: Data splitting: Split the data into training set, validation set, and test set;

[0036] S4: Model selection: Select a suitable machine learning model according to the problem type, such as regression, classification, clustering;

[0037] S5: Model training: Use the training set data to train the model and adjust the parameters to optimize the model performance;

[0038] S6: Model evaluation: Use the validation set data to evaluate the model performance and select the optimal model;

[0039] S7: Model deployment: Deploy the trained model into the actual application for real-time data calculation and prediction.

[0040] Specifically, the driving module 4 includes a control main board connected to the film winding machine. The control main board has a power network circuit connected to an external input unit.

The MCU module U1 selects the GD32F303RCT6 model; the MCU module U1 is connected with a crystal oscillator X2 and an interface H1. The MCU module U1 and the communication unit support the mobile phone APP to remotely control the turning off and on of the film winding machine, which is convenient for users to operate anytime and anywhere.

Through each node, the surrounding information such as weather, pests, light, temperature and humidity in the shed, air composition, soil moisture, pipeline water volume, water and fertilizer composition, water pump, gate valve, light medium, etc. that need to be collected can be obtained.

[0041] Furthermore, the power network circuit includes a buck regulator U2 of the TPS54360BDDAR model. Its input voltage ranges from 4.5V to 60V, and the output voltage ranges from 0.8V to 58.8V.

When there is no load, it can reduce the power supply current to 146 μA, effectively improving the light load efficiency. The internal control output voltage starts a ramp to control the startup process and eliminate overshoot. The buck regulator U2 is connected with an interface P2 and a linear regulator LDO1 of the CJ7805 model; the power network circuit has an isolated power supply module U5 of the B0505S-1WR3 model, and the isolated power supply module U5 is connected with a linear regulator U6 of the AMS1117-3.3 model.

[0042] Furthermore, the communication unit includes an isolated transceiver U3 of the ISO3082DW-R model, which provides high-speed signal isolation function with an isolation voltage up to 2.5 kVrms. It supports RS-485 and RS-422 communication standards and can achieve half-duplex or full-duplex communication modes. In the half-duplex mode, data can be transmitted in two directions but not simultaneously; the full-duplex mode allows data to be transmitted simultaneously in two directions, thus meeting different communication requirements. The isolated transceiver U3 is connected to a gas discharge tube TV1 of the 4532-091-LF model, and the communication unit is equipped with a wire-to-board pin socket U17 of the ZX-XH2.54-3PZZ model. This communication unit supports communication through serial port protocol, ROLA protocol, or 4G and 5G communication, ensuring the stability and flexibility of data transmission. The communication unit has functions such as thermal shutdown and receiver input fault protection. The thermal shutdown function can automatically stop working when the chip temperature is too high, preventing the chip from being damaged due to overheating. The receiver input fault protection can protect the receiver circuit inside the chip when the input signal is abnormal, ensuring the reliability of the entire communication system.

[0043] In addition, the output unit includes transistor output optocouplers U8 and U9 of the EL357N model. The transistor output optocoupler U8 is connected to a single-pole double-throw contact power relay RELAY2 of the SRD-12VDC-SL-C model through a triode Q2 of the SS8050 model, and the transistor output optocoupler U9 is connected to a single-pole double-throw contact power relay RELAY3 of the SRD-12VDC-SL-C model through a triode Q1 of the SS8050 model; the output unit is equipped with a terminal block P1 of the WJ500V-5.08-2P model; the output unit includes a transistor output optocoupler U23 of the EL357N model, and the transistor output optocoupler U23 is connected to a triode Q7 of the SS8050 model, and the transistor output optocoupler U23 is equipped with a wire-to-board pin socket U24 of the WAFER-XH2.54-6PZZ model. The output unit is connected to the driving motor of the film winding machine, and the transistor output optocouplers U8 and U9 achieve electrical isolation and signal transmission, ensuring the stable operation of the system.

[0044] Meanwhile, the signal input unit includes transistor output optocouplers U13 and U14 of the EL357N model. The transistor output optocoupler U13 is connected to a triode Q5 of the SS8050 model, and the transistor output optocoupler U14 is connected to a triode Q6 of the SS8050 model. The signal input unit uses the same model of transistor output optocouplers U13 and U14 as the output unit, thus achieving double electrical and signal isolation for input and output and ensuring the safety of the system.

[0045] Visibly, the control main board has a transistor output optocoupler U11 of the EL357N model, and the transistor output optocoupler U11 is connected to a triode Q3 of the SS8050 model; the control main board has a pin header U22 of the PM254-1-05-Z-8.5 model.

[0046] Obviously, the Internet of Things 2 includes a sensing layer and an execution layer, and the sensing layer and the execution layer are connected to the application layer through the network layer. The Internet of Things 2 uploads the information of the drive module 4 to the server, and the mobile phone APP remotely operates the controller through the relay of the server to realize the shutdown of the film rolling machine.

[0047] A digital remote control method for a film rolling machine based on an intelligent controller. Under normal weather conditions, farmers can remotely fine-tune the opening degree of the film rolling machine through the mobile phone APP according to the growth needs of crops to achieve ideal ventilation and temperature conditions. When disaster weather comes, such as heavy rain, strong wind, etc., farmers can quickly close the film rolling machines of multiple greenhouse sheds through the mobile phone APP to avoid damage to the sheds and disasters to the crops. Users can complete the networking operation of the device by scanning the QR code or entering the code.
