Description

Technical Field

[0001] This utility model relates to the field of film winding machine technology, and in particular to an intelligent electric film winding machine. Background Technology

[0002] Currently, greenhouse cultivation, as an important component of modern agriculture, directly impacts crop yield and quality through the level of automation in its environmental control. The greenhouse film rolling machine, as a key actuator controlling greenhouse ventilation and lighting, is of paramount importance. Currently, greenhouse film rolling machines have undergone a development process from purely manual to electric, and then to preliminary intelligent systems.

[0003] Early film-rolling machines relied entirely on manual operation, which was time-consuming, labor-intensive, and difficult to control precisely. Later electric film-rolling machines, while achieving basic motor drive, primarily relied on simple local button or timer controls, preventing remote intervention and rapid response to real-time temperature, humidity, and weather changes (such as sudden rainfall). Furthermore, these devices lacked status feedback mechanisms; users were unaware of malfunctions such as film jamming or motor overload, potentially leading to crop damage or equipment failure.

[0004] In recent years, some film winding machines with single remote control functions have emerged, but their level of intelligence is limited. They can usually only perform simple start and stop operations and cannot form a complete solution integrating environmental perception, intelligent decision-making, remote control, and fault diagnosis. They still have significant shortcomings in terms of operational reliability, environmental adaptability, and ease of maintenance. Specifically: 1. They cannot automatically start and stop based on temperature thresholds; 2. They lack a rainwater sensing linkage mechanism; 3. They cannot detect and warn of abnormal motor loads; 4. They cannot accurately monitor and provide feedback on the equipment's operating status (such as the degree of film winding opening).

[0005] Therefore, there is an urgent need in this field for a highly integrated, intelligent, reliable, and fully remotely monitored and managed electric film winding device to solve the technical problems of existing technologies, such as single control, lack of sensing, and difficulty in operation and maintenance. Utility Model Content

[0006] The purpose of this invention is to provide an intelligent electric film winding machine. By integrating a control motherboard with a 4G communication module and a signal processing unit, this invention solves the technical problem of traditional equipment's inability to be remotely controlled and interact with data. It achieves the technical effect of building the core of the Internet of Things and realizing comprehensive remote management. This structure allows users to remotely issue commands (such as manual control or setting automatic travel) anytime, anywhere via mobile phone apps or other terminals. The equipment can also provide real-time feedback on its operating status, environmental data, and fault information to the user's mobile phone, greatly improving the convenience and timeliness of management.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: an intelligent electric film winding machine, comprising:

[0008] A mechanical drive mechanism, comprising a motor housing, a wound motor housed within the motor housing, a gearbox connected to the output end of the wound motor, and a rotating shaft driven to rotate by the gearbox;

[0009] The control mechanism includes a control housing and a control motherboard disposed within the control housing, on which a signal processing unit and a 4G communication module are integrated.

[0010] The signal processing unit is electrically connected to the 4G communication module and the winding motor, respectively, and is used to interact with the mobile network platform through the 4G communication module, receive control commands from the user terminal, and generate drive signals according to the control commands to control the operation of the winding motor.

[0011] Furthermore, the signal processing unit is electrically connected to an input control module, a display module, a rain detection module, a temperature detection module, a current detection module, a speed detection mechanism, and a motor drive mechanism; the signal processing unit is used to receive detection signals from the input control module, the rain detection module, the temperature detection module, the current detection module, and the speed detection mechanism, and to drive the motor drive mechanism to work.

[0012] Furthermore, the rotational speed detection mechanism includes:

[0013] A counting gear is fixedly mounted on the rotating shaft, and the counting gear is installed inside the control housing via a gear fixing bracket.

[0014] A speed sensor is fixedly mounted on one side of the gear mounting bracket and is used to detect the number of rotations or the speed of the counting gear.

[0015] The speed sensor is electrically connected to the signal processing unit.

[0016] Furthermore, the signal processing unit is configured to: determine whether the rotating shaft is operating normally based on the signal fed back by the speed detection mechanism, and send a fault alarm message to the user terminal through the 4G communication module when an abnormal operation is determined.

[0017] Furthermore, the signal processing unit is configured to receive temperature signals from the temperature detection module and rainwater signals from the rainwater detection module, and accordingly automatically control the start, stop, or direction of the winding motor.

[0018] Furthermore, the control housing is provided with ventilation holes for heat dissipation.

[0019] Furthermore, the gearbox is a gear reduction gearbox.

[0020] The advantages of this utility model are:

[0021] 1. This utility model solves the technical problem of traditional devices being unable to achieve remote intelligent control and data interaction by setting up a control motherboard integrating a 4G communication module and a signal processing unit. It achieves the technical effect of building the core of the Internet of Things and realizing comprehensive remote management. This structure allows users to remotely issue commands (such as manual control or setting automatic schedules) anytime, anywhere via mobile phone apps and other terminals. The device can also provide real-time feedback on its operating status, environmental data, and fault information to the user's mobile phone, greatly improving the convenience and timeliness of management.

[0022] 2. This utility model solves the technical problem of the equipment's inability to intelligently sense the environment and respond automatically by setting and integrating multiple environmental sensors such as rainwater detection modules and temperature detection modules, and electrically connecting them with the signal processing unit. This achieves the technical effect of realizing unmanned intelligent operation and improving the accuracy of greenhouse management. The signal processing unit can continuously receive signals such as temperature and rainwater, and compare them with preset thresholds, thereby automatically controlling the start, stop, and direction of the wound motor (such as automatic ventilation when the temperature is too high, and automatic closure of the greenhouse when it rains). This truly realizes environment-based automated intelligent control, effectively protecting the growth environment of crops inside the greenhouse.

[0023] 3. This utility model solves the technical problems of unmonitored equipment operation status and unpredictable faults by setting up a speed detection mechanism composed of a counting gear and a speed sensor, connected to a signal processing unit. It achieves real-time monitoring, intelligent diagnosis, and proactive safety protection. The signal processing unit analyzes the speed signal to calculate the actual position of the film roll and determine whether abnormalities such as jamming or overload have occurred. Once an operational abnormality is detected, an alarm message is immediately sent to the user via a 4G communication module, enabling predictive maintenance, preventing equipment from operating with defects or further damage, and ensuring production safety.

[0024] 4. This utility model solves the technical problem of the inability to detect the motor load status by setting a current detection module and electrically connecting it to the signal processing unit, thus achieving the technical effect of dual protection and in-depth diagnosis. By monitoring the motor's operating current, the signal processing unit can effectively distinguish between different states such as overload, stall, and no-load, providing a more accurate basis for fault diagnosis. Combined with the speed signal, it forms a more complete safety protection system. Attached Figure Description

Figure 3 This is a circuit block diagram of the present invention. Figure 4 This is the 4G communication circuit diagram of this utility model. Figure 5 This is the control circuit diagram of this utility model. Figure 6 This is the power supply circuit diagram of this utility model, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this embodiment provides an intelligent electric film winding machine, which mainly includes two parts: a mechanical drive mechanism and a control mechanism.

[0037] The mechanical drive mechanism is the core power unit for performing the film rolling action, including: Motor housing 1: Serving as the external protective shell of the wound motor, made of metal, possessing good heat dissipation and mechanical strength, used to fix and protect the internal motor components. Wound motor: Housed within motor housing 1, serving as the core power source, using an AC or DC motor design, capable of providing stable rotational power. Its characteristics include high torque and stable speed, suitable for heavy-load applications in greenhouse film rolling. Gearbox 2: Directly connected to the output end of the wound motor; in this embodiment, a gear reducer is preferred. Internally, through multi-stage gear transmission, it converts the high-speed rotation of the motor into low-speed, high-torque output to meet the speed and force requirements of film rolling operations, ensuring a smooth and reliable film rolling process. Rotating shaft 3: Driven by gearbox 2, serving as the final power output component. Rotating shaft 3 is directly connected to the greenhouse film rolling rod, achieving the opening and closing of the greenhouse film through forward and reverse rotation.

[0038] The control mechanism of this invention includes a control housing 4: serving as a protective shell for the control motherboard 8, typically made of engineering plastic or metal. To ensure heat dissipation of the internal electronic components, ventilation holes 401 are provided on the control housing 4, forming a natural airflow channel to effectively prevent performance degradation or damage to the electronic components due to high temperatures. The control motherboard 8: located inside the control housing 4, integrates a signal processing unit: implemented by a microprocessor (MCU) or single-chip microcomputer, responsible for processing all input signals, executing control algorithms, and outputting control commands. The 4G communication module in this invention uses an industrial-grade 4G communication chip with a built-in SIM card, enabling stable connection with the cloud platform via mobile network for remote data interaction.

[0039] The rotational speed detection mechanism in this invention is used to monitor the working status of the film winding machine in real time. It includes a counting gear 6, fixedly mounted on a rotating shaft 3 and rotating synchronously with it. This gear is securely mounted inside the control housing 4 via a gear fixing bracket 5, ensuring the stability of the detection. A rotational speed sensor 7, fixedly mounted on one side of the gear fixing bracket 5, specifically employing a Hall effect sensor or photoelectric sensor, is used for non-contact detection of the number of teeth or rotational speed of the counting gear 6. The rotational speed sensor 7 is electrically connected to the signal processing unit, transmitting the detection signal to the signal processing unit in real time. A temperature monitoring module uses a digital temperature sensor to monitor the ambient temperature in real time. A rainwater monitoring module uses a rainwater sensor, installed externally to detect rainfall. A current monitoring module uses a current sensor (such as a Hall effect current sensor) to monitor the operating current of the winding motor in real time.

[0040] The input control module of this invention includes local buttons, switches, etc., for manual control on-site. The display module uses a digital tube or LCD screen to display information such as equipment status and environmental parameters. The motor drive mechanism in this invention, as a power drive component, receives control signals from the signal processing unit and drives the wound motor. Relays or solid-state relays are typically used to achieve forward and reverse rotation control of the motor.

[0041] Working principle: The remote intelligent control process of this utility model includes: the user issues a control command through a mobile phone applet or other terminal → the command is sent to the cloud platform through the mobile network → the cloud platform sends the command to the device's 4G communication module through the 4G network → the 4G communication module transmits the command to the signal processing unit → the signal processing unit parses the command and generates the corresponding drive signal → the drive signal is transmitted to the motor drive mechanism → the motor drive mechanism controls the wound motor to perform the corresponding action (forward rotation, reverse rotation or stop).

[0042] The automatic environmental response process of this utility model includes: the temperature detection module / rainwater detection module collects environmental data in real time → the detection signal is transmitted to the signal processing unit → the signal processing unit compares the detection value with the preset threshold → when the environmental parameters exceed the set range (such as the temperature is too high or rainfall is detected), the control command is automatically generated → the control command is transmitted to the motor drive mechanism → the corresponding film rolling action is executed (such as ventilation or closing the shed).

[0043] The status monitoring and fault diagnosis process of this utility model includes: the speed sensor 7 monitors the rotation speed of the rotating shaft 3 in real time → the speed signal is transmitted to the signal processing unit → the signal processing unit analyzes the speed through an algorithm to calculate the film winding position and operating status → simultaneously, the current detection module monitors the motor operating current → the signal processing unit performs fault diagnosis by combining the speed and current signals: when the speed abnormally decreases and the current abnormally increases, it is judged as jamming or overload. When the speed abnormally increases and the current abnormally decreases, it is judged as slippage or no-load. When an abnormality is detected, an alarm message is immediately sent to the user terminal through the 4G communication module.

[0044] The local manual control process of this utility model includes: the user operates by inputting the button of the control module → the operation signal is directly transmitted to the signal processing unit → the signal processing unit generates the drive signal → the motor is controlled to perform the corresponding action, and the current status is displayed on the display module.

[0045] Through the coordinated operation of the aforementioned multiple modules, this invention achieves intelligent, remote, and automated control of greenhouse film rolling devices, greatly improving the level of intelligence in agricultural production and management efficiency.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
