Description

Technical Field

[0001] The present invention relates to the technical field of seedling raising equipment, and in particular to an intelligent wireless environment monitoring device for a three-dimensional seedling raising factory. Background Art

[0002] Production is the key core of industrial development. At present, the transfer of rural labor force to cities and the problem of population aging are becoming increasingly prominent, and the full mechanization of rice production has become an inevitable trend. Currently, the biggest obstacle to the full mechanization of rice planting lies in the mechanization of transplanting, and the effectiveness of transplanting mechanization mainly depends on the quality of seedlings, which largely relies on the seedling raising substrate. For a long time, the substrate used for rice seedling raising has mostly been nutrient soil, but using nutrient soil as the seedling raising substrate has many drawbacks. For example, the amount of soil taken is extremely large, it is difficult to obtain, it will damage arable land, and it is also prone to soil-borne diseases. In addition, some soilless substrates on the market are difficult to be widely promoted and applied on a large scale due to their unstable physical and chemical properties, poor water and fertilizer retention capacity, and high price. These situations have made the demand for large-scale, intelligent, and unmanned rice seedling raising production more urgent.

[0003] The seedling raising rack provides guarantee for the healthy growth of seedlings through a standardized and normalized seedling raising mode. For example, the application of factory-style seedling raising in agricultural production is becoming increasingly widespread. It has the advantages of high technological content, large production scale, low seedling raising cost, excellent seedling quality, saving seeds and labor, etc. This seedling raising method relies on the precise and semi-precise sowing technology, sows seeds with the help of a mechanized production line, and adopts the form of centralized cultivation in a greenhouse or in the field, which is deeply favored by farmers and the market.

[0004] In the prior art, CN116897747B discloses a four-point type vertical three-dimensional seedling raising equipment, which includes a three-dimensional seedling raising rack and a plurality of seedling raising trays installed on the three-dimensional seedling raising rack. The equipment makes each seedling raising tray maintain a horizontal posture and move up and down in an elliptical trajectory around the three-dimensional seedling raising rack through a conveying chain and a tray anti-overturning guiding device. For the structural schematic diagram of the three-dimensional seedling raising rack, see Figure 10 , in this device, a single chain is used to achieve vertical up-and-down cyclic conveying, that is, a seedling raising device can operate independently as a unit without affecting other units. If a fault occurs in the chain drive system of a certain device, it will not affect other devices, which can effectively ensure the reliability of the operation of the seedling raising equipment and can be applicable to various seedling raising scales of large, medium and small sizes, and its practicability is better. A plurality of three-dimensional seedling raising racks are arranged in a row and are set in the space of a seedling raising greenhouse to form a three-dimensional seedling raising factory.

[0005] However, traditional seedling-raising racks have obvious deficiencies. They lack effective monitoring means and cannot real-time grasp the environmental parameters on the seedling-raising racks, such as temperature and humidity, light intensity, air pressure, etc. Most of the existing seedling-raising racks are not equipped with real-time monitoring equipment. Growers can only rely on manual observation and experience to manage the seedling-raising process. This method is inefficient and extremely likely to affect the growth effect of the seedlings due to subjective judgment errors. Especially for the seedling-raising equipment that moves up and down in an elliptical trajectory in this kind of seedling-raising factory, it is very difficult to accurately conduct environmental monitoring. Therefore, it is particularly important to optimize the design of the seedling-raising rack and add real-time monitoring functions. Summary of the Invention

Moreover, the moving directions of the two wireless environmental monitoring devices at both ends of the elliptical trajectory are opposite.

The energy harvesting component provides walking power for the power driving device.

[0010] As a preferred technical solution, a stroke monitoring sensor corresponding to the intermittent sliding device is arranged at the end of the seedling-raising tray. The probe of the stroke monitoring sensor faces the intermittent sliding device and is used for monitoring the moving position of the intermittent sliding device.

[0011] As a preferred technical solution, the top end of the support body is fixed on the arched light-transmitting protective tube, and the bottom end of the support body is fixed on the battery cover. A wire harness through-channel is arranged inside the support body. The wire harness through-channel communicates the arched light-transmitting protective tube with the battery cover. Wire harness guiding rubber plugs are arranged at both inner ends of the wire harness through-channel.

[0012] As a preferred technical solution, protective tube covers are installed at both bottom ends of the arched light-transmitting protective tube. The top end of the light-transmitting monitoring cabin is rotatably and detachably connected to the protective tube covers. An energizing component is arranged between the protective tube covers and the light-transmitting monitoring cabin. When the light-transmitting monitoring cabin is connected to the protective tube covers, the energizing component is connected, and the monitoring load element is electrically connected to the storage battery through the energizing component.

Detailed implementation manners

[0019] The present invention will be further described below in conjunction with the drawings and embodiments. In the following detailed description, only some exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those of ordinary skill in the art can recognize that, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the drawings and the description are illustrative in nature and are not used to limit the protection scope of the claims.

[0020] Such as Figure 1 and Figure 2As shown in the figure, several three-dimensional seedling raising racks are arranged in the three-dimensional seedling raising factory. A plurality of seedling raising trays 100 are installed on the three-dimensional seedling raising racks. Each of the seedling raising trays 100 maintains a horizontal posture and moves up and down in an elliptical trajectory around the three-dimensional seedling raising rack in a cyclic and reciprocating manner. Two wireless environment monitoring devices 200 are provided on each three-dimensional seedling raising rack. The two wireless environment monitoring devices 200 are arranged on two different seedling raising trays 100. The positions of the two wireless environment monitoring devices 200 in their respective corresponding seedling raising trays 100 are the same, and they move synchronously and intermittently along the seedling raising tray 100. One of the wireless environment monitoring devices 200 is located in the inner circle of the elliptical trajectory, and the other wireless environment monitoring device 200 is located in the outer circle of the elliptical trajectory. And the moving directions of the two wireless environment monitoring devices 200 at both ends of the elliptical trajectory are opposite.

[0021] Two wireless environment monitoring devices 200 are provided on each three-dimensional seedling raising rack and are used as "one for use and one for backup" to avoid the inability to achieve the monitoring purpose after a certain monitoring device fails. And the two devices monitor simultaneously. Through the differences between the collected data, abnormal judgments can be made on the surrounding environment, and self-check judgments can also be made on the two detection devices to determine whether the monitoring devices are malfunctioning.

[0022] The two wireless environment monitoring devices 200 are arranged on the same side (left or right) of the two seedling raising trays 100, so that one of the wireless environment monitoring devices 200 can move in the inner circle of the elliptical trajectory, and the other wireless environment monitoring device 200 can move in the outer circle of the elliptical trajectory. That is, one of the wireless environment monitoring devices 200 monitors the environment inside the three-dimensional seedling raising rack, and the other wireless environment monitoring device 200 monitors the environment outside the three-dimensional seedling raising rack. The monitoring data results of the simultaneous monitoring of the inside and outside of the three-dimensional seedling raising rack can more accurately express the surrounding environment of the seedling raising tray 100. The moving directions of the two wireless environment monitoring devices 200 at both ends of the elliptical trajectory are opposite. That is, when one of the wireless environment monitoring devices 200 moves upward, the other wireless environment monitoring device 200 moves downward. It can monitor the upper and lower positions simultaneously in the same time period, and combined with the internal and external dislocation monitoring, the purpose of multi-directional monitoring can be achieved.

[0023] The wireless environment monitoring device 200 moves back and forth along the length direction of the seedling raising tray 100, which can effectively monitor the parameters of the seedlings on the seedling tray on the plane layer. At the same time, since the seedling raising tray 100 moves up and down in an elliptical trajectory around the three-dimensional seedling raising rack in a cyclic and reciprocating manner, the wireless environment monitoring device 200 moves with the seedling raising tray 100, which can realize the monitoring of the environmental space in the vertical direction. Therefore, the combination of the plane layer and the vertical direction can ensure the all-round environmental monitoring of all positions of the three-dimensional seedling raising rack, and then comprehensive monitoring or precise monitoring according to needs can be realized, providing all-round data support for the healthy growth of rice seedlings.

[0024] See Figures 2 to 7 As shown in Figures 2 to 7 , the wireless environment monitoring device 200 includes a support body 210, an energy harvesting component 220, a monitoring load component 230, and an intermittent sliding device 240. The support body 210 serves as the installation base for the energy harvesting component 220 and the monitoring load component 230, and is indirectly installed on the intermittent sliding device 240.

[0025] See Figures 2 to 4 As shown in Figures 2 to 4 , the intermittent sliding device 240 is installed at one side edge of the seedling tray 100. The energy harvesting component 220 provides power for the intermittent sliding device 240 to drive the energy harvesting component 220 and the monitoring load component 230 to reciprocate along the length direction of the seedling tray 100. The intermittent sliding device 240 includes a guiding slide rail 241 fixedly provided at one side edge of the seedling tray 100. The guiding slide rail 241 extends along the length direction of the seedling tray 100, and the length of the guiding slide rail 241 basically corresponds to the length of the seedling tray 100, so that the wireless environment monitoring device 200 can reciprocate at both ends of the plane of the seedling tray 100. A traveling slide seat 242 is slidably installed on the guiding slide rail 241, and the battery cover is fixed on the traveling slide seat 242. A power driving device is further provided between the traveling slide seat 242 and the guiding slide rail 241. The energy harvesting component 220 provides traveling power for the power driving device. The wireless environment monitoring device 200 can intermittently move along the guiding slide rail 241 and stay at multiple positions on the plane of the seedling tray 100 for multi-point intermittent monitoring. The monitoring data of multiple points is uploaded to the central control system and can be used for data analysis. The power driving device includes a motor, a gear, and a rack structure. The motor drives the gear to rotate and move along the rack provided at the guiding slide rail 241, and the energy harvesting component 220 provides power for the motor. Of course, the power driving device can also be an electromagnet, and the electromagnetic principle is used to realize the magnetic levitation movement between the guiding slide rail 241 and the traveling slide seat 242, and the energy harvesting component 220 provides electric energy for the electromagnet.

[0026] In order to obtain the monitoring position of the wireless environment monitoring device 200 and prevent it from colliding with the end of the seedling tray 100, a travel monitoring sensor 243 corresponding to the intermittent sliding device 240 is provided at the end of the seedling tray 100. The probe of the travel monitoring sensor 243 faces the intermittent sliding device 240 to monitor the moving position of the intermittent sliding device 240, so that the monitoring stop position can be accurately controlled. The monitoring stop position is combined with the monitoring data corresponding to this point, and the data is uploaded to the central control system. The central control system can form a three-dimensional monitoring table.

[0027] See Figures 5 to 8 , the energy harvesting component 220 includes a solar panel 221, an inverter, and a storage battery 222. At the top of the support 210, there is installed an arched light-transmitting protective tube 223 that is hollow inside and has an opening facing downward. Inside the arched light-transmitting protective tube 223, there is installed an arched bracket 224. A plurality of the solar panels 221 are arranged and installed along the arc-shaped outer surface of the arched bracket 224. At the bottom end of the support 210, there is installed a battery shield 225, and a plurality of the storage batteries 222 are arranged inside the battery shield 225. The solar panel 221, the inverter, and the storage battery 222 cooperate to convert solar energy into electrical energy, and its principle belongs to the prior art and will not be elaborated here.

[0028] Since the wireless environmental monitoring device 200 not only moves horizontally by itself but also moves vertically up and down in a cyclic manner following the seedling-raising tray 100, the position where it receives light in the three-dimensional seedling-raising factory is not fixed. In order to ensure that the solar panel 221 can utilize more light, an arched bracket 224 is adopted. Since its structure is arched itself, after placing the solar panel 221 on the arched outer surface, at this time, the positions where a plurality of solar panels 221 receive light are different, that is, they can receive light from more angles. This enables it to absorb solar energy more effectively at different times and seasons, improving the utilization rate of light; when a certain solar panel 221 is blocked by other seedling-raising trays 100 at a certain position or the light is insufficient due to a change in the light angle, other solar panels 221 can still absorb solar energy at other angles. This arrangement method of arranging the solar panels 221 in an arched shape improves the overall light utilization rate and is more suitable for the environment with variable positions in this application.

[0029] To ensure the installation of the arched bracket 224 and the solar panel 221, this application selects an arched light-transmitting protective tube 223 that is hollow inside and has an opening facing downward. This arched and light-transmitting arc-shaped tube design makes the device structure stable, increases the collection of light. Compared with the straight tube structure, the U-shaped bent part can receive light from more angles within the same installation space. This enables it to absorb solar energy more effectively at different times and seasons, improving the utilization rate of light. At the same time, it also improves the energy storage efficiency. The arched structural design increases the capacity of the energy storage medium inside the protective tube. Since the volume of the arched light-transmitting protective tube 223 is relatively large, it can accommodate more energy storage medium, can absorb and store a large amount of energy when the light is sufficient, and release heat during periods such as insufficient light or at night, thereby improving the energy storage performance of the system and ensuring the stability of the energy supply.

[0030] The battery shield 225 protects the internal battery 222 on the one hand, and is fixed on the walking slide 242 as a base on the other hand. Its structural design has a far-reaching impact on the stability and safety of the system. Therefore, the present application designs the battery shield 225 structurally, and selects a semi-cylindrical arched shield. The semi-cylinder has good structural strength and can show excellent compressive resistance in the face of environmental changes and possible external shocks. For example, when encountering strong winds, the seedling raising system may be subject to strong winds. The semi-cylindrical structure can effectively disperse the wind, withstand external forces and not easily deform, thereby protecting the internal battery from damage. Its stability enables the seedling raising system to operate normally under complex environmental conditions, greatly reducing the probability of failure and damage caused by structural problems. On the other hand, the rectangular structure has obvious disadvantages when it is subjected to external forces. Stress concentration is prone to occur at the corners of the rectangular body. When subjected to external force impact, the pressure on these corners is much higher than that on other areas. Compared with the semi-cylindrical structure, its overall strength and stability are poor. In a complex seedling raising environment, such as when heavy rain causes water impact or drastic temperature changes cause thermal expansion and contraction, the transparent battery cabin with a rectangular structure is more easily damaged, thereby affecting the normal power supply and operation of the seedling raising system.

[0031] Since the monitoring load component 230 is equipped with a load element, and the load element is a key component to ensure the accuracy of the monitoring results, when the central processing system finds that the load element data is inaccurate, the load element needs to be replaced. Therefore, the light-transmitting monitoring cabin 231 must ensure that the replacement is convenient and the power supply is more convenient; therefore, the two bottom ends of the arched light-transmitting protective tube 223 are installed with protective tube covers 226. On the one hand, the protective tube covers 226 protect and separate the arched light-transmitting protective tube 223. The protective tube covers 226 can be snap-fitted and threadedly connected to the end of the arched light-transmitting protective tube 223, and on the other hand, they are convenient for the installation of the light-transmitting monitoring cabin 231. The top of the light-transmitting monitoring cabin 231 is rotatably and detachably connected to the protective tube cover 226. The light-transmitting monitoring cabin 231 and the protective tube cover 226 can be installed by threaded connection, and a power-on component is provided between the protective tube cover 226 and the light-transmitting monitoring cabin 231. When the light-transmitting monitoring cabin 231 and the protective tube cover 226 are connected, the power-on component is connected, and the monitoring load element is electrically connected to the battery 222 through the power-on component; when the light-transmitting monitoring cabin 231 and the protective tube cover 226 are separated, the power-on component is disconnected. The design of this power-on component ensures that the power supply is automatically disconnected and connected when the light-transmitting monitoring cabin 231 is disassembled and installed, which can reduce the difficulty of disassembling and assembling the line.

[0032] The combined design of the transparent monitoring chamber and the arched light-transmitting protective tube 223 not only realizes the structural stability of the device, but also significantly improves the light collection and energy storage efficiency of the arched light-transmitting protective tube 223.

[0033] The energizing component includes a first energizing terminal seat 227 installed in the light-transmitting monitoring chamber 231. An elastic probe 228 is fixed to the top end of the first energizing terminal seat 227. The first energizing terminal seat 227 is electrically connected to the monitoring load element through a power cord and a connector; a probe through-hole 229 is provided on the surface of the protective tube cover 226. A second energizing terminal seat 2210 is provided in the protective tube cover 226 corresponding to the probe through-hole 229. The second energizing terminal seat 2210 is electrically connected to the storage battery 222 through a power cord and a connector. A docking terminal 2211 is provided at the bottom end of the second energizing terminal seat 2210. When the light-transmitting monitoring chamber 231 and the protective tube cover 226 are connected, the head of the elastic probe 228 passes through the probe through-hole 229 and abuts against the docking terminal 2211. When the elastic probe 228 contacts the docking terminal 2211, it means that the power supply is connected. At this time, the storage battery 222 can supply power to the monitoring load element. The elastic probe 228 is directly located at the rotation center of the light-transmitting monitoring chamber 231, and the docking terminal 2211 is also located at the center of the protective tube cover 226, ensuring that when the light-transmitting monitoring chamber 231 is rotationally installed, the elastic probe 228 can always contact the docking terminal 2211. Of course, the light-transmitting monitoring chamber 231 can also be installed in a snap-fit manner.

[0034] The monitoring load component 230 includes two light-transmitting monitoring chambers 231, which are respectively installed at the two bottom ends of the arched light-transmitting protective tube 223. One of the light-transmitting monitoring chambers 231 extends above the inner side of the seedling-raising tray 100, and the other light-transmitting monitoring chamber 231 extends outside the seedling-raising tray 100. Monitoring load elements 232 are respectively provided in the two light-transmitting monitoring chambers 231, and the monitoring load elements 232 are electrically connected to the storage battery 222.

[0035] In the process of raising rice seedlings, in order to realize the real-time and accurate collection of complex environmental parameters on the seedling raising rack, a special light-transmitting monitoring cabin 231 is used. The monitoring load element 232 is cleverly placed in the light-transmitting monitoring cabin 231 to carry out all-round monitoring of the environment around the seedling raising rack. Since the data involved in the rice seedling raising process is extremely complicated and numerous, a single light-transmitting monitoring cabin 231 is often stretched in terms of data capacity storage. Therefore, it is particularly necessary to set up two light-transmitting monitoring cabins 231, which can provide more powerful storage support for huge amounts of data. The two light-transmitting monitoring cabins 231 have clear division of labor and different work focuses. The light-transmitting monitoring cabin 231 located on the inside focuses on the monitoring of soil moisture parameters and light intensity of rice seedling raising. With high-precision sensors, it deeply detects subtle changes in soil moisture and provides key soil environment data for seedling growth. The light-transmitting monitoring cabin 231 located outside is extremely sensitive to the air conditions inside the seedling raising system, and can quickly and accurately monitor multiple air parameters including air humidity, air pressure, oxygen content, carbon dioxide concentration, etc., and provide real-time feedback on the air quality in the seedling raising space, helping to create the most suitable air environment for seedling growth. Depending on the different monitoring focuses, the monitoring load elements 232 in the two light-transmitting monitoring cabins 231 also correspond to different ones, using sensors with different functions and different numbers of sensors.

[0036] The light-transmitting monitoring cabin 231 is a hemispherical structure with a hollow interior and an open top. A load element bracket for mounting the monitoring load element 232 is provided inside the light-transmitting monitoring cabin 231 , and a plurality of air permeable holes 233 are arranged on the outer peripheral surface of the light-transmitting monitoring cabin 231 .

[0037] The light-transmitting monitoring cabin 231 adopts a hemispherical structure. Since a sphere is a highly symmetrical and uniform geometric shape, the physical properties of the sphere in all directions are relatively consistent in space. This allows sensors placed therein to collect data in a relatively balanced manner in all directions, thereby reducing data collection deviations caused by asymmetric shapes.

[0038] The sensor generates heat during operation. If the heat is not dissipated in time, it may lead to performance degradation, shortened lifespan or even malfunction. The ventilation holes 233 provide a heat dissipation channel for the heat, which helps to maintain the appropriate temperature inside the sensor cabin and ensure the normal operation of the sensor module. The design of two rows of holes can make the heat dissipation more uniform and avoid the occurrence of local overheating. These ventilation holes 233 can also serve as a transmission channel for wireless signals, which is conducive to the communication between the sensors in the monitoring cabin and external devices. For example, when the monitoring cabin needs to send the collected data on the growth and environmental parameters of rice to the remote monitoring center or interact with other devices, the wireless signal can be transmitted more smoothly through the holes, reducing signal blocking and attenuation, and improving the stability and efficiency of communication.

[0039] The size of the small holes can usually be designed to be relatively small, which can not only meet the requirements of heat dissipation and communication, but also prevent foreign matters such as dust and water vapor from entering the sensing cabin to a certain extent and damage the sensing module. Compared with the heat dissipation or communication methods with large openings, the small holes can better protect the internal electronic components and improve the environmental adaptability and reliability of the sensing cabin.

[0040] The top end of the support body 210 is fixed on the arched light-transmitting protection tube 223, the bottom end of the support body 210 is fixed on the battery protection cover 225, a wire harness through-channel is arranged inside the support body 210, the wire harness through-channel communicates the arched light-transmitting protection tube 223 and the battery protection cover 225, and wire harness guiding rubber plugs are arranged at both ends inside the wire harness through-channel.

[0041] The wireless environment monitoring device 200 further includes a control module and a wireless communication module. The control module is used to control the operation of the intermittent sliding device 240 to achieve accurate fixed-point monitoring. The wireless communication module is arranged in the light-transmitting monitoring cabin 231, and the monitoring load elements 232 are all connected to the wireless communication module. Through the wireless communication module, data can be uploaded to the central control system, and the central control system analyzes and processes the data to achieve remote monitoring and intelligent management.

[0042] The main functions of this embodiment include: 1. The seedling raising frame is equipped with wireless sensors, which can collect and display multiple environmental parameters in real time, including air temperature and humidity, light intensity, air pressure, soil humidity and carbon dioxide content, making the seedling raising environment data clear at a glance.

[0043] 2. The energy collection component 220 has the ability to autonomously absorb light, and while realizing power supply, it can also store energy to provide continuous power support for the stable operation of the system.

[0044] 3. The central control system is responsible for analyzing the received data. Once the environmental parameters deviate from the preset reasonable range, the system will immediately automatically send out a warning signal to ensure that the seedling raising environment is in a suitable state.

[0045] 4. Growers can use the central control system or mobile devices to know in real time whether the seedling raising environment is suitable, remotely control the relevant equipment on the seedling raising frame, and take targeted adjustment measures in time.

[0046] 5. The system stores the collected data, and growers can query the historical data at any time to clearly master the environmental change trend during the seedling raising process. By deeply analyzing these historical data, growers can summarize experience, optimize the seedling raising strategy, and then improve the yield and quality of crops.

[0047] 6. The system is equipped with an intermittent sliding device 240, which can conduct more three-dimensional monitoring of the parameters on the seedling tray, obtain the status information of the seedling tray comprehensively, and assist in precise seedling raising.

[0048] 7. The intermittent sliding device 240 is equipped with a high-precision stroke monitoring sensor 243. When the platform approaches the edge, the sensor triggers a stop command and simultaneously sends a return signal. This mechanism ensures the continuity of monitoring, avoids the risk of collision, and improves the reliability and accuracy of the device.

[0049] For the realization of the functions of this embodiment, see Figure 9 : 1. Energy collection: The device collects solar energy through the solar panel 221, and the storage battery 222 in the device can store the excess solar energy to cope with the changeable weather and continuously supply energy to the device.

[0050] 2. Data acquisition: The monitoring load element 232 can obtain the parameters of the seedlings on the seedling tray in the plane direction through the intermittent sliding device 240. Combining with the up and down cyclic movement of the seedling raising tray 100, more three-dimensional and comprehensive parameters can be obtained on the vertical axis. Finally, the data is uploaded to the cloud and displayed on the screen.

[0051] 3. Data upload: The data in the cloud can be remotely viewed and controlled in real time by the user. At the same time, an intelligent prediction model is established through the training data, and finally a real-time feedback on the seedling parameters is achieved.

[0052] 4. Data processing and analysis: The central control system analyzes the received data. When the environmental parameters exceed the preset reasonable range, the system will automatically send out a warning signal. This step involves the real-time processing and intelligent analysis of data and is the key to realizing intelligent control.

[0053] 5. Remote monitoring and adjustment: The grower can remotely view the seedling raising environment data through the central control system or a mobile device and make adjustments as needed. This step provides the ability of remote monitoring, enabling the grower to respond to environmental changes in a timely manner and optimize the seedling raising strategy.

[0054] 6. Historical data storage and query: The system will store the collected data, and the grower can query the historical data at any time to understand the environmental change trend during the seedling raising process. By analyzing the historical data, the grower can summarize experience, optimize the seedling raising strategy, and improve the yield and quality of crops.
