Description

Technical Field

[0001] This invention relates to the field of plant monitoring devices, specifically to a field monitoring device and method for endangered plants. Background Technology

[0002] Garlic cactus is a national second-class protected rare plant, a monotypic genus endemic to my country, mainly distributed in mountainous areas above 300 meters in western Guangxi and eastern Yunnan. Due to competition for habitat resources, space limitations, and predatory grazing by animals, seedlings and saplings of garlic cactus are scarce, putting it in an endangered state. To protect and rescue garlic cactus, it is necessary to monitor its growth environment. However, when monitoring the root system, it is difficult to obtain comprehensive data on root growth and distribution, making root research difficult. Moreover, current monitoring methods usually require operators to carry the corresponding monitoring equipment to the field to collect data, which requires high technical skills, is time-consuming and labor-intensive, and the protection effect is relatively average. In addition, the function of a single monitoring device is limited, and it is impossible to achieve integrated monitoring of root, crown, soil physical environment and climate environment. Multiple devices need to be carried to the field, resulting in low monitoring efficiency. Summary of the Invention

[0003] The main objective of this invention is to overcome the deficiencies of the aforementioned background technology and provide a field monitoring device and method for endangered plants.

[0004] To achieve the above objectives, the present invention proposes a field monitoring device for endangered plants, comprising an equipment box, a root data acquisition module, a canopy data acquisition module, an environmental data acquisition module, and a control module. The root data acquisition module, canopy data acquisition module, and environmental data acquisition module are all electrically connected to the control module. The control module is mounted on the equipment box. The root data acquisition module includes a microroot cannula, a first camera, a lead screw, a transmission assembly, and a drive component. The top end of the microroot cannula is detachably connected to the bottom end of the equipment box, allowing for easy transport to the field. The lead screw extends from inside the equipment box to the lower end of the microroot cannula. The lead screw is connected to the drive component via the transmission assembly. The lead screw has a sliding seat and a rotating seat, which are rotatably connected. The first camera is mounted on the rotating seat. A first positioning groove is provided on the outer peripheral wall of the sliding seat, and a first slide rail corresponding to the first positioning groove is provided on the inner wall of the microroot cannula. When the driving component drives the transmission assembly to rotate, and the lead screw rotates synchronously, the sliding seat cannot rotate due to the locking effect of the first slide rail, and can only move along the lead screw. The movement of the sliding seat drives the rotating seat to move and rotate synchronously, thereby enabling the first camera to move and rotate 360 ​​degrees while shooting, so that the entire root system of the endangered plant can be captured by a single first camera.

[0005] Furthermore, the bottom end of the micro-root cannula is detachably connected to a pointed tip, which has a hollow structure, and a vent hole is provided on the lower support plate of the lead screw. The pointed tip facilitates the insertion of the micro-root cannula into the ground, and the desiccant stored inside the pointed tip can dry the inside of the micro-root cannula, preventing fogging inside the micro-root cannula from affecting the shooting of the first camera.

[0006] Furthermore, a hanging ring is provided on the outer circumference of the sliding seat, and the hanging ring abuts against the inner wall of the micro-root canal. The hanging ring can scrape the inner wall of the micro-root canal to prevent water droplets from adhering to the inner wall and affecting the shooting of the first camera.

[0007] Furthermore, the transmission assembly includes a worm gear and a worm, the worm gear is fixed to the top of the lead screw, the worm gear is meshed with the worm gear, one end of the worm gear is connected to the output end of the drive component, and both the transmission assembly and the drive component are disposed inside the device box.

[0008] Furthermore, the canopy data acquisition module includes a second camera, a first drive shaft, and a first telescopic sleeve. The second camera is fixed to the end of the first telescopic sleeve, which is sleeved around one end of the first drive shaft. A first bevel gear is located in the middle of the first drive shaft, and a second bevel gear meshing with the first bevel gear is located at the end of the worm gear away from the drive component. A recessed first helical track is provided on the inner wall of the first telescopic sleeve, and a first drive pin is provided on the outer wall of the first drive shaft. The first drive pin and the first helical track are slidably connected. A second positioning groove is provided along the axial direction on the outer wall of the first telescopic sleeve, and a second slide rail corresponding to the second positioning groove is provided on the inner wall of the device box. A through hole is provided on the side wall of the device box, allowing the first telescopic sleeve to extend the second camera out of the device box or retract it into the device box. When it is necessary to capture canopy data of the endangered plant to be tested, the second camera extends out of the device box to capture the image. After capturing the image, it is retracted into the device box for storage, preventing the second camera from being exposed to the atmosphere for a long time and corroded by wind and sun, thus extending the service life of the second camera.

[0009] Furthermore, the environmental data acquisition module includes a soil environment acquisition unit and an atmospheric environment sensor. The soil environment acquisition unit includes a support cylinder, a soil environment sensor, a second drive shaft, and a second telescopic sleeve. The support cylinder is vertically arranged around the bottom of the device box and is fitted over the second telescopic sleeve. The soil environment sensor is fixed to the bottom end of the second telescopic sleeve. The second telescopic sleeve is fitted over one end of the second drive shaft. The top end of the second drive shaft extends into the device box and is provided with a third bevel gear. The end of the first drive shaft is provided with a fourth bevel gear. The third bevel gear and the fourth bevel gear are meshed together. The inner wall of the second telescopic sleeve is provided with a recessed second helical track. The outer wall of the second drive shaft is provided with a second drive pin. The second drive pin and the second helical track are slidably connected. The outer wall of the second telescopic sleeve is provided with a third positioning groove along the axial direction. The inner wall of the support cylinder is provided with a third slide rail corresponding to the third positioning groove, so that the second telescopic sleeve can drive the soil environment sensor to extend out of the support cylinder and insert into the soil for measurement, or retract into the support cylinder for storage. When soil physical environment data needs to be collected, the soil environment sensor extends out from the support cylinder and is inserted into the soil for measurement. After the data collection is completed, it retracts into the support cylinder for storage, thus preventing the soil environment sensor from being corroded by being inserted into the soil for a long time and effectively extending the service life of the soil environment sensor.

[0010] Furthermore, the soil environment sensor includes a soil temperature and humidity sensor, a soil ion concentration sensor, and a soil pH sensor.

[0011] Furthermore, the atmospheric environment monitoring sensor is located outside the device box, and the atmospheric environment monitoring sensor includes an air temperature and humidity sensor, a light sensor, a wind speed sensor, and a carbon dioxide concentration sensor.

[0012] Furthermore, the control module includes a controller, a communication module, a battery, and a solar panel. The communication module and the solar panel are respectively disposed on the top of the device box, and the controller and the battery are disposed inside the device box. The communication module, the battery, and the solar panel are all electrically connected to the controller.

[0013] The present invention also discloses a method for monitoring endangered plants using the above-mentioned field monitoring device, comprising the following steps: S1. Insert the field monitoring device next to the plant to be monitored, so that the microroot tube is inserted into the ground until the bottom of the support tube contacts the ground. S2. Control signals are remotely sent to the communication module via the cloud management platform. After receiving the control signals, the communication module transmits them to the controller. Alternatively, the controller sends signals to the controller at regular intervals via the timing crystal oscillator inside the controller. The controller controls the drive components to rotate, enabling the transmission components to drive the lead screw, the first drive shaft, and the second drive shaft to rotate synchronously. This allows the first camera to move downwards inside the microroot canal while rotating to capture images of the root system of the plant to be monitored around the microroot canal. The second camera extends from inside the device box to the outside to capture images of the canopy of the plant to be monitored. The soil environment sensor extends from the support cylinder and inserts into the ground to detect the soil around the plant to be monitored. The atmospheric environment sensor detects the atmosphere around the plant to be monitored. S3. The data collected by the first camera, the second camera, the soil environment sensor, and the atmospheric environment sensor are transmitted back to the cloud management platform for analysis and processing through the communication module, so as to realize the integrated monitoring of the roots, crown, soil physical environment, and climate environment of the plant to be monitored.

[0014] The beneficial effects of this invention include: through the coordinated use of the driving component, transmission assembly, lead screw, sliding seat, and rotating seat, the first camera can move up and down and rotate 360 ​​degrees while capturing plant root distribution data in the micro-root canal, requiring only one first camera to capture the entire root distribution of endangered plants; after the endangered plant field monitoring device of this invention is installed around the plant to be monitored, the control module controls the root data acquisition module, canopy data acquisition module, and environmental data acquisition module to automatically collect the corresponding data to be measured and transmit it back to the cloud management platform for analysis and processing, so as to realize integrated monitoring of root, canopy, soil physical environment, and climate environment, eliminating the need to carry multiple devices to the site and effectively improving monitoring efficiency.

[0031] Please see Figures 1 to 11One embodiment of the endangered plant field monitoring device discloses a device box 1, a root data acquisition module 2, a canopy data acquisition module 3, an environmental data acquisition module 4, and a control module. The root data acquisition module 2, canopy data acquisition module 3, and environmental data acquisition module 4 are all electrically connected to the control module, which is mounted on the device box 1. The root data acquisition module 2 includes a micro-root cannula 201, a first camera 202, a lead screw 203, a transmission assembly 204, and a drive component 205. The top end of the micro-root cannula 201 is detachably connected to the bottom end of the device box 1 via threads. After connection, the micro-root cannula 201 is perpendicular to the device box 1. The lead screw 203 extends from the device box... The screw 203 extends internally to the lower end of the micro-root canal 201. An upper support plate 208 and a lower support plate 207 are respectively provided at the upper and lower ends of the screw 203 for fixation, ensuring that the screw 203 can rotate on the central axis of the micro-root canal 201. The screw 203 is connected to the drive component 205 via a transmission assembly 204. A sliding seat 2031 and a rotating seat 2032 are respectively provided on the screw 203. The rotating seat 2032 is rotatably connected to the sliding seat 2031. Specifically, the sliding seat 2031 and the rotating seat 2032 are coaxially arranged. An annular groove 2035 is formed on the top of the sliding seat 2031, and a corresponding annular groove 2035 is formed on the bottom edge of the rotating seat 2032. The annular outward flange 2036 allows the sliding seat 2031 and rotating seat 2032 to rotate relative to each other after assembly, but they cannot be separated. The first camera 202 is mounted on the rotating seat 2032, placing the first camera 202 entirely within the relatively enclosed micro-root canal 201, preventing corrosion from the external environment. The shooting direction is adjusted to face the inner wall of the transparent micro-root canal 201. A first positioning groove 2033 is provided on the outer peripheral wall of the sliding seat 2031, and a first slide rail 2011 corresponding to the first positioning groove 2033 is provided on the inner wall of the micro-root canal 201. Specifically, the first slide rail 2011 engages with the first positioning groove 2033. When the driving component... When the transmission component 204 rotates driven by 205 and the lead screw 203 rotates synchronously, the sliding seat 2031 cannot rotate due to the jamming of the first slide rail 2011. It can only move up and down along the lead screw 203. During the movement of the sliding seat 2031, the rotating seat 2032 moves synchronously. The rotating seat 2032 is also connected to the lead screw 203, so it can rotate relative to the sliding seat 2031. The first camera 202 is installed on the rotating seat 2032. Therefore, the first camera 202 can automatically move up and down and rotate 360 ​​degrees while shooting. Only one first camera 202 is needed to capture the full distribution of the root system of endangered plants.

[0032] In a specific example, the bottom end of the micro-root cannula 201 is detachably connected to a pointed tip 206 via a thread. The pointed tip 206 has a hollow structure, and a vent hole 2071 is provided on the lower support plate 207 of the lead screw 203. The pointed tip 206 makes it easier to insert the micro-root cannula 201 into the ground, and the detachable design facilitates transportation to the field. When installing the pointed tip 206 into the bottom of the micro-root cannula 201, a desiccant can be placed inside the pointed tip 206 to prevent fogging inside the micro-root cannula 201 due to long-term insertion below the ground, which would cause the first camera 202 to capture unclear images.

[0033] In a preferred embodiment, a hanging ring 2034 is provided on the outer circumference of the sliding seat 2031, and the hanging ring 2034 abuts against the inner wall of the micro-root canal 201. The hanging ring 2034 is made of rubber. When the sliding seat 2031 moves, the hanging ring 2034 can scrape the inner wall of the micro-root canal 201 to prevent debris and water droplets from adhering to the inner wall and affecting the shooting of the first camera 202.

[0034] In a specific embodiment, the transmission assembly 204 includes a turbine 2041 and a worm gear 2042. The turbine 2041 is fixed to the top of the lead screw 203, and the worm gear 2042 is meshed with the turbine 2041. One end of the worm gear 2042 is connected to the output end of the drive component 205. Specifically, the drive component 205 is either a servo motor or a stepper motor. Both the transmission assembly 204 and the drive component 205 are housed inside the equipment box 1 to prevent them from being exposed to wind and sun during outdoor work, thus affecting their service life.

[0035] In a preferred embodiment, the canopy data acquisition module 3 includes a second camera 301, a first drive shaft 302, and a first telescopic sleeve 303. The second camera 301 is fixed to the end of the first telescopic sleeve 303. The first telescopic sleeve 303 is sleeved on one end outside the first drive shaft 302. A first bevel gear 304 is provided in the middle of the first drive shaft 302. A second bevel gear 2043 that meshes with the first bevel gear 304 is provided at the end of the worm gear 2042 away from the drive member 205. A recessed first spiral track 3031 is provided on the inner sidewall of the first telescopic sleeve 303. The outer wall of the device box 1 is provided with a first drive pin 3021, which is slidably connected to the first spiral track 3031. The outer wall of the first telescopic sleeve 303 is provided with a second positioning groove 3032 along the axial direction. The inner wall of the cover of the device box 1 is provided with a second slide rail 101 corresponding to the second positioning groove 3032. The side wall of the device box 1 is provided with a through hole 102, so that the first telescopic sleeve 303 can carry the second camera 301 out of the device box 1 or retract into the device box 1 through the through hole 102. At the same time, the cover of the device box 1 is also provided with a heat dissipation hole 103. When the drive component 205 drives the worm gear 2042 to rotate, the second bevel gear 2043 drives the first bevel gear 304 to rotate, and the first drive shaft 302 rotates synchronously. When the first drive pin 3021 rotates, it drives the first telescopic sleeve 303 to move telescopically, thereby driving the second camera 301 to move. When it is necessary to capture the canopy data of the endangered plant to be tested, the second camera 301 extends out of the device box 1 to capture the data. After the data capture is completed, it is retracted into the device box 1 to extend the service life of the second camera 301. In this embodiment, there are two sets of canopy data acquisition modules 3, which are respectively set on both sides of the device box 1. The two sets of canopy data acquisition modules 3 are connected by the connecting shaft 10 and use the same drive component 205 to perform synchronous operation. Moreover, the shooting direction of the second camera 301 is set to face the canopy of the endangered plant to be tested.

[0036] In a preferred embodiment, the environmental data acquisition module 4 includes a soil environment acquisition unit 401 and an atmospheric environment monitoring sensor 402. The soil environment acquisition unit 401 is used to collect soil data around the endangered plant to be tested, and the atmospheric environment monitoring sensor 402 is used to collect weather data around the endangered plant to be tested. The soil environment acquisition unit 401 includes a support cylinder 4011, a soil environment sensor 4012, a second drive shaft 4014, and a second telescopic sleeve 4013. The support cylinder 4011 has four sets, which are vertically arranged around the bottom of the equipment box 1 and are fitted outside the second telescopic sleeve 4013. The soil environment sensor 4012 is fixed to the bottom end of the second telescopic sleeve 4013. The second telescopic sleeve 4013 is fitted outside one end of the second drive shaft 4014. The top end of the second drive shaft 4014 extends into the interior of the equipment box 1 and is provided with a third bevel gear 4015 at the top end. A fourth bevel gear 4015 is provided at the end of the first drive shaft 302. 15 and the fourth bevel gear 305 are meshed and connected. A recessed second spiral track 4016 is provided on the inner wall of the second telescopic sleeve 4013. A second drive pin 4017 is provided on the outer peripheral wall of the second drive shaft 4014. The second drive pin 4017 and the second spiral track 4016 cooperate to slide and connect. A third positioning groove 4018 is provided on the outer wall of the second telescopic sleeve 4013 along the axial direction. A third slide rail 4019 corresponding to the third positioning groove 4018 is provided on the inner wall of the support cylinder 4011. The third slide rail 4019 is inserted into the third positioning groove 4018 to prevent the second telescopic sleeve 4013 from rotating relative to the support cylinder 4011. When the second drive shaft 4014 rotates, the second drive pin 4017 drives the second telescopic sleeve 4013 to telescopically move, so that the second telescopic sleeve 4013 can drive the soil environment sensor 4012 to extend out of the support cylinder 4011 and insert into the soil for measurement, or retract into the support cylinder 4011 for storage.

[0037] In a specific example, the soil environment sensor 4012 includes a soil temperature and humidity sensor, a soil ion concentration sensor, and a soil pH sensor. The soil temperature and humidity sensor is used to detect the soil temperature and humidity, the concentration of potassium, sodium, and magnesium ions in the soil, and the soil pH value of the endangered plant being tested.

[0038] In a specific example, the atmospheric environment monitoring sensor 402 is installed outside the device box 1. The atmospheric environment monitoring sensor 402 includes an air temperature and humidity sensor, a light sensor, a wind speed sensor, and a carbon dioxide concentration sensor, which are used to detect the temperature and humidity, light intensity, wind speed, and carbon dioxide concentration of the environment in which the endangered plant to be tested is located.

[0039] In a specific example, the control module includes a controller 5, a communication module 6, a battery 7, and a solar panel 8. The communication module 6 and the solar panel 8 are respectively located on the top of the device box 1, while the controller 5 and the battery 7 are located inside the device box 1. The communication module 6, the battery 7, and the solar panel 8 are all electrically connected to the controller 5. In this embodiment, the controller 5 samples any one of an MCU microcontroller, a single-chip microcomputer, or a PLC, and the controller 5 integrates a timing crystal oscillator circuit. The battery 7 is used to store the electrical energy converted by the solar panel 8 and to power the entire monitoring device so that it can still work normally when there is no mains power in the field. The communication module 6 is used to establish a remote communication connection with the cloud management platform.

[0040] The field monitoring device of the present invention controls a drive component 205 to rotate via a control module. This allows the first camera 202 to move and rotate within the microroot canal 201 while collecting root images of the endangered plant under test. The second camera 301 automatically extends from the device box 1 to collect canopy images of the endangered plant under test. After collection, the second camera 301 automatically retracts into the device box 1, preventing it from being exposed to the elements and corroded. The soil environment sensor 4012 automatically descends along the support cylinder 4011 and inserts into the bottom surface to collect soil data on the growth of the endangered plant under test. After collection, the soil environment sensor 4012 automatically rises away from the ground, preventing it from being corroded by prolonged exposure to the soil. This effectively extends the service life of the first camera 202, the second camera 301, and the soil environment sensor 4012.

[0041] In another embodiment, a method for monitoring endangered plants using a field monitoring device is also disclosed, comprising the following steps: S1. The operator holds the handle 9 of the field monitoring device and inserts the field monitoring device next to the plant to be monitored, 0.5-2 meters away from the trunk of the plant to be monitored, so that the micro root canal 201 is inserted into the ground and the bottom end of the support cylinder 4011 is in contact with the ground to complete the installation and fixation of the equipment. S2. The cloud management platform 11 remotely sends control signals to the communication module 6. After receiving the control signals, the communication module 6 transmits them to the controller 5. Alternatively, the controller 5 sends signals to the controller 5 at regular intervals via the timing crystal oscillator in the controller 5. The controller 5 controls the drive component 205 to rotate, so that the transmission component 204 can drive the lead screw 203, the first drive shaft 302 and the second drive shaft 4014 to rotate synchronously. This allows the first camera 202 to move downwards in the micro-root canal 201 while rotating to capture 360-degree images of the root system of the plant to be monitored around the micro-root canal 201. The second camera 301 extends from inside the device box 1 to the outside to capture images of the canopy of the plant to be monitored. The soil environment sensor 4012 extends from the support cylinder 4011 and inserts into the ground to detect the soil around the plant to be monitored. The atmospheric environment monitoring sensor 402 detects the atmosphere around the plant to be monitored. After the detection is completed, the first camera 202 rises to the bottom of the device box 1, the second camera 301 retracts into the inside of the device box 1, and the soil environment sensor 4012 rises into the inside of the support cylinder 4011 and leaves the ground for storage. S3. The data collected by the first camera 202, the second camera 301, the soil environment sensor 4012, and the atmospheric environment monitoring sensor 402 are converted and processed by the controller 5, and then transmitted back to the cloud management platform 11 through the communication module 6 for further analysis and processing. This realizes the integrated monitoring of the roots, crown, soil physical environment, and climate environment of the plant to be monitored. Operators do not need to go to the growth site of the endangered plant to monitor the endangered plant in a timely manner, which is conducive to the protection and rescue of endangered plants in the wild.
