Description

A mobile greenhouse environment data collection device Technical Field

[0001] This utility model relates to the field of greenhouse technology, and in particular to a mobile greenhouse environment data collection device. Background Technology

[0002] Dynamic acquisition of greenhouse space environment information enables farmers to understand the distribution of the greenhouse environment and provides data support for effective environmental regulation. In existing technologies, the common approach is to deploy multiple greenhouse environmental parameter acquisition instruments, which is not only costly and requires a lot of equipment, but also affects crop growth. Some technologies use mobile robots equipped with acquisition sensors to acquire the distribution of the greenhouse environment autonomously or remotely, but this is costly overall and has certain requirements for the ground surface in the greenhouse.

[0003] Chinese patent CN217587912U discloses a smart greenhouse environmental inspection robot, specifically including a robot body and a support frame mounted on the robot body. A power mechanism is installed on the side of the support frame, and a PLC controller is installed on the top of the robot body. One end of the PLC controller is connected to an electric telescopic rod via a wire. A slide rail is movably connected inside the support frame, and indicator poles are connected at equal intervals along the top of the slide rail. This invention utilizes the control system inside the robot body to automatically activate the PLC controller and the electric telescopic rod, allowing the indicator poles to automatically rise, achieving a highly visible indication and enabling greenhouse staff to easily observe which area has a problem. The transmission mechanism automatically limits and fixes the rising indicator poles, ensuring they remain in a stable state. However, this solution involves installing the entire robot on a track, resulting in high deployment costs and placing significant demands on the greenhouse's load capacity. The high temperature and humidity environment also has a considerable impact on the track and the equipment.

[0004] Chinese patent CN114297907A discloses a method and apparatus for predicting the spatial distribution of greenhouse environments. Based on multiple sets of environmental characteristics at the current and previous times of the prediction point, a feature vector matrix comprising multiple sets of time-series features is determined. These environmental features include both internal and external greenhouse environmental characteristics. The feature vector matrix is ​​then input into the convolutional network of a trained prediction model for feature extraction, yielding an extracted global feature vector. This global feature vector is then input into the time-series network of the prediction model, outputting predicted results for temperature, humidity, light intensity, and carbon dioxide content after a preset time period. This method primarily employs deep learning for regional environmental prediction, but its data source still relies on multi-point sensor data collection, resulting in high costs and complex data acquisition. Summary of the Invention

[0005] This utility model provides a mobile greenhouse environment data acquisition device to solve the shortcomings of existing technologies, such as high cost of multi-point fixed sensors that affect crop growth, high deployment cost of mobile robots that have strict requirements on ground load, high energy consumption for continuous monitoring, and inaccurate positioning. It achieves the technical effects of low-cost and lightweight deployment, no occupation of planting space, and automatic positioning control.

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0037] The following describes a mobile greenhouse environment data collection device according to the present invention with reference to Figures 1-3.

[0038] This utility model embodiment provides a greenhouse environment mobile data acquisition device, including: an environment acquisition device 1, a track 2, a transmission component 3, a drive device 4, and a controller 7. The track 2 is arranged on the top of the greenhouse along a first direction, which can be the length direction of the greenhouse. Multiple acquisition points are spaced apart on the track 2, and each acquisition point is equipped with a position detection component. The transmission component 3 is movably arranged on the track 2 and is connected to the environment acquisition device 1. It is used to drive the environment acquisition device 1 to move along the track 2 along the first direction and stop at each acquisition point to complete the acquisition of environmental information. The drive device 4 is connected to the transmission component 3 and is used to drive the transmission component 3 to move along the first direction. The controller 7 is a PLC controller 7 and is electrically connected to the drive device 4. It is used to control the start and stop of the drive device 4.

[0039] As can be seen from the above solution, this utility model optimizes greenhouse space utilization by suspending the track 2, transmission component 3, and environmental acquisition device 1 on the greenhouse roof, away from the high humidity and dust environment on the ground. It does not occupy ground planting space. Compared to ground-based mobile robots or multi-point fixed sensors, it eliminates the need to modify the greenhouse floor or lay a large number of devices, reducing hardware costs and installation complexity. It also avoids obstructing crop growth areas by existing ground-based mobile devices and reduces the risk of contact wear between equipment and crops. Acquisition points can be flexibly arranged at intervals according to greenhouse monitoring needs, without requiring full coverage. While ensuring data validity, it reduces the number of devices and further reduces the space occupied in the greenhouse. The combination of transmission component 3 and track 2 allows for a lightweight design, reducing the impact on the greenhouse roof. With low load requirements, it can be adapted to various types of greenhouses such as bamboo, wood, and steel structures, reducing the high load requirements. The track 2 is set with sampling points at intervals. The position detection component only triggers an electrical signal when the hook moves to the point, waking up the environmental sampling device 1 to work. This avoids the energy waste of continuous operation of traditional mobile robots or continuous monitoring by multiple sensors, and improves the sampling efficiency. The transmission component 3 drives the environmental sampling device 1 to stop and collect data at different points, which can obtain environmental data such as temperature, humidity, and light intensity of the greenhouse space. Compared with fixed multi-point sensors, dynamic coverage can be achieved with fewer devices, and the data is closer to the actual environmental distribution. By adjusting the length of track 2, the number of sampling points, and the transmission speed, it can be flexibly adapted to greenhouses of different areas to meet personalized monitoring needs.

[0040] Optionally, the track 2 is made of aluminum alloy or stainless steel profile, with low weight. Its cross-section is I-shaped or rectangular. The track 2 can be hung on the crossbeam at the top of the greenhouse by a fixing plate. The fixing plate can be L-shaped, with one end fixed to the two ends of the track 2 by bolts, and the other end connected to the lower surface of the crossbeam at the top of the greenhouse by bolts or clips, so that the track 2 is horizontally suspended below the crossbeam.

[0041] In this embodiment, the environmental acquisition device 1 includes a housing, and a sensor module, a wireless communication module 11 and a microprocessor 12 are disposed inside the housing. The sensor module includes a temperature and humidity sensor 13, a light intensity sensor 14 and a CO2 sensor 15, which are used to collect greenhouse environmental parameters. The microprocessor 12 is electrically connected to the sensor module and the wireless communication module 11 respectively, and is used to process the collected data and send it to an external terminal through the wireless communication module 11.

[0042] As shown in Figure 3, it also includes a power supply module 16, which is used to supply power to the sensor module, the wireless communication module 11, the microprocessor 12 and the drive device 4.

[0043] In some specific embodiments, the transmission component 3 is a ring chain or belt, and the upper and lower surfaces of the track 2 are provided with grooves that are adapted to the transmission component 3. The transmission component 3 is embedded in the groove and extends along the length direction of the track 2. The driving device 4 is connected to the transmission component 3 for driving the transmission component 3 to move on the upper and lower surfaces of the track 2.

[0044] With this configuration, the grooves on the upper and lower surfaces of track 2 are adapted to the shape of the transmission component 3, forming a limiting structure to prevent the transmission component 3 from shifting left or right during movement. This ensures that the environmental acquisition device 1 moves precisely to each acquisition point along the length of track 2, improving positioning accuracy. The ring chain or belt is embedded in the groove, forming a closed transmission path with track 2. Together with the drive device 4, it enables smooth cyclic movement of the transmission component 3, avoiding the influence of the greenhouse ground on traditional wheel transmissions. This makes it suitable for complex terrains such as muddy fields and ridges. Furthermore, the frictional transmission noise between the ring chain or belt and the groove is lower than that of traditional wheel transmissions. The ring chain or belt is a standardized component with low cost. When the component is worn, it can be directly disassembled and replaced without replacing the entire track 2, reducing maintenance costs.

[0045] Furthermore, the drive device 4 is fixed to one end of the track 2 by a bracket. The drive device 4 includes a motor, and a transmission wheel is provided on the output shaft of the motor. The transmission wheel is a gear or a pulley. The transmission wheel is connected to the transmission component 3. The motor rotates and drives the transmission component 3 to move in a cyclical manner in the groove, thereby driving the environmental acquisition device 1 connected to the transmission component 3 to move synchronously.

[0046] Preferably, the depth of the groove is greater than or equal to the thickness of the transmission component 3. With this configuration, the two side walls of the transmission component 3 are completely wrapped by the side walls of the groove, forming an embedded limit. This can effectively resist lateral forces during the transmission process, such as the tension when the chain turns or the offset force when the belt runs, preventing the transmission component 3 from leaving the track 2 and ensuring the stability and reliability of the transmission effect.

[0047] In this embodiment, the environmental acquisition device 1 is attached to the transmission component 3 via a movable hook 5 and moves synchronously with the transmission component 3. The position detection component includes magnets 6 and reed switches 8. The number of magnets 6 is the same as the number of acquisition points and their positions correspond one-to-one. The magnets 6 are glued to the track 2 or fixed by a slot, and the magnetic poles of the magnets 6 face the movable hook 5. The reed switches 8 are set on the movable hook 5. When the movable hook 5 approaches the magnets 6, the reed switches 8 are attracted to wake up the environmental acquisition device 1 with an electrical signal.

[0048] This setup enables non-contact positioning, such as the reed switch 8 and magnet 6 being triggered by a magnetic field, eliminating mechanical contact losses. Compared to traditional mechanical switches or encoders, it is more stable and durable in the complex environment of a greenhouse.

[0049] Specifically, the reed switch 8 contains two elastic springs made of magnetic material. When there is no magnetic field, the two springs are separate. When influenced by the magnetic field of the magnet 6, the two springs are magnetized, generating a magnetic force that attracts each other. When the magnetic force exceeds the elastic force of the springs themselves, the springs will close, causing the internal circuit of the reed switch 8 to conduct. This generates an electrical signal, indicating that the movable hook 5 has reached the acquisition point where the magnet 6 is installed. Through the electrical connection between the reed switch 8 and the controller 7, the generated electrical signal is transmitted to the microprocessor 12. The microprocessor 12 receives this electrical signal. Afterwards, the signal will be processed according to the preset program logic, and control commands will be issued to make the environmental acquisition device 1 collect data. The acquisition time is very short and the motor does not need to stop running. When the movable hook 5 continues to move with the transmission component 3 and moves away from the magnet 6, the two reeds in the reed switch 8 will separate because it is no longer affected by its magnetic field. The environmental acquisition device 1 will no longer collect data and the acquisition work will be completed. The motor will drive the transmission component 3 and the movable hook 5 to continue to move to the next acquisition point. When the transmission component 3 moves to the end of the track 2, the controller 7 will control the motor to stop or reverse.

[0050] In this embodiment, the movable hook 5 includes a hook body and a connecting part. The connecting part is fixed on the transmission component 3. The top of the hook body is detachably connected to the connecting part, such as by bolts, buckles or magnetic attraction, which facilitates quick assembly and disassembly of the environmental collection device 1 during maintenance. The bottom of the hook body forms a hook-shaped structure for hanging the environmental collection device 1. The reed switch 8 is embedded in the connecting part. The shell of the connecting part is made of waterproof and corrosion-resistant materials such as ABS engineering plastic, which seals the reed switch 8 inside, isolating it from the influence of water vapor and dust in the greenhouse and extending the service life of the reed switch 8.

[0051] With this configuration, when the environmental data acquisition device 1 needs to replace the sensor or be repaired, it is not necessary to disassemble the entire transmission component 3. The device can be removed simply by disconnecting the detachable connection between the hook body and the connecting part, which reduces the difficulty of high-altitude operations. In addition, the hook body can be designed as a universal interface, and by replacing the hook structure of different specifications, it can be adapted to environmental data acquisition devices 1 of different weights or shapes, thereby improving the expandability of the device.

[0052] 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 this 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 of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
