Description

Technical Field

[0001] The present invention relates to the technical field of field data collection, and in particular to a system and method for collecting data of field non-network monitoring equipment using a drone. Background Art

[0002] The current data collection methods for field monitoring equipment mainly include the following: (1) traditional manual collection; (2) transmitting data to cloud servers by adding 4G / 5G network modules to the equipment; (3) building wireless ad hoc network transmission; and (4) low-throughput data collection based on drones using proprietary equipment. In general, each method has its own characteristics, but the disadvantages are also very obvious. For traditional manual collection methods, in a field without a network environment, it is necessary to manually cross mountains and hills to the device location to copy the data in the storage medium, which is costly and extremely dangerous; for 4G / 5G transmission, in a field environment, there is almost no network coverage or the network is extremely unstable, and data is easily lost during the data transmission process; for the construction of wireless ad hoc network equipment, although the effect is good, the construction cost is very high and it is difficult to popularize it to ordinary users; and drone-based data collection, as a new type of field storage medium data collection and data transmission method, does not require manual crossing mountains and hills to copy data to the device location. The flight control platform controls the drone equipped with a data transmission module to fly near the device, and connects to the device point-to-point wirelessly, and copies the data of the device storage medium to the drone's storage medium through wireless transmission, thereby realizing remote data collection at low cost.

[0003] However, existing drone data collection devices all rely on low-throughput wireless communication. This transmission method, designed and developed for proprietary equipment, can only provide data transmission capabilities for a single device. The code size of the transmission interface is relatively large, the implementation complexity is high, and wireless transmission is extremely unstable. This low-throughput data collection method can only transmit very small amounts of data, such as text messages, and cannot transmit large files such as images and videos, resulting in very low data collection efficiency. Limited by the instability and ultra-low transmission speed of wireless transmission, it is impossible to provide an efficient and stable high-throughput data collection solution for today's increasingly large amounts of field monitoring data. Therefore, the development of a system for collecting data from field monitoring equipment without a network using drones that can overcome the limitations of wireless transmission and efficiently and stably perform high-throughput data collection is an urgent problem that needs to be solved. Summary of the Invention

[0004] In response to the technical problems existing in the prior art, the first purpose of the present invention is to provide a system for drones to collect data from field non-network monitoring equipment, so as to enable drones to collect large-throughput data from field non-network monitoring devices and ensure lossless transmission of data.

[0036] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] like Figure 1-11As shown, a system for collecting data from outdoor network-free monitoring equipment using a drone is shown. The system primarily comprises: a monitoring device 4, a first data acquisition device 1, a docking device 3, a second data acquisition device 2, and a drone 5. The monitoring device 4, the first data acquisition device 1, the docking device 3, and the second data acquisition device 2 are connected in series via wires. The monitoring device 4 is positioned near an outdoor monitoring location 6 and collects field monitoring data. The field monitoring location 6 can be a forest, lake, or other outdoor location. The monitoring device 4 and the first data acquisition device 1 are secured to a tree trunk with straps, while the docking device 3 is secured to the top of the tree. The monitoring device 4 can be a wildlife monitoring infrared camera, an animal voiceprint monitor, a tree diameter-at-breast height monitor, or an ecological and meteorological monitoring device. In this embodiment, the monitoring device 4 is a wildlife monitoring infrared camera.

[0038] like Figure 1 and Figure 5 As shown, a first data acquisition device 1 is electrically connected to a monitoring device 4. The monitoring device 4 is connected to the first data acquisition device 1 via a conductive cable and an SD card extension cable, for collecting field monitoring data from the monitoring device 4. A docking station 3 is used to park a drone 5 and is electrically connected to the first data acquisition device 1. Specifically, the docking station 3 is connected to the first data acquisition device 1 via an optical fiber cable and a DC 12V conductive cable. A second data acquisition device 2 is mounted on the bottom of the drone 5 and mates with the data transmission port of the docking station 3 to collect field monitoring data from the first data acquisition device 1. The drone 5 provides power to the second data acquisition device 2. Mounting the second data acquisition device 2 on the bottom of the drone 5 allows the drone 5 to withstand greater loads and torque, counteracting airflow during flight and improving stability. The docking station 3 switches the first data acquisition device 1 to field monitoring mode when it senses the second data acquisition device 2 is moving away. When the docking station 3 senses the second data acquisition device 2 approaching and docking, it switches the first data acquisition device 1 to data output mode.

[0039] Continue to refer to Figure 1 The monitoring device 4 includes a third shell 401, which is fixed near the field monitoring position 6 by a strap. A power supply module 402, a monitoring module 403 and a fourth communication interface module are arranged inside the third shell 401. The fourth communication interface module is electrically connected to the power supply module 402 and the monitoring module 403 respectively. The power supply module 402 is used to power the monitoring device 4, the monitoring module 403 is used to collect field monitoring data, and the fourth communication interface module includes a fourth external wiring port arranged at the bottom of the third shell 401.

[0040] Then refer to Figure 1 and Figure 6, which shows a specific embodiment of the first data acquisition device 1. The first data acquisition device 1 includes a first shell 101. One side of the first shell 101 is open and is detachably provided with a first cover 101b. The first shell 101 and the first cover 101b are connected together through a PCB isolation copper column. A waterproof rubber ring is wrapped around the outer edge of the first cover 101b. During assembly, the waterproof rubber ring is pressed against the outer edge of the first shell 101 to achieve the purpose of outdoor waterproofing and fog prevention. A mounting bracket 101c is provided on the outer side of the first cover 101b, which is used to fix the first shell 101 near the field monitoring position 6. The mounting bracket 101c has multiple threaded holes and is fixed to the strap by bolts. A status indicator light 101a is provided on the other side of the first shell 101, which is used to display the real-time working status of the device, such as the real-time storage medium read and write permission status, data transmission mode status, etc. The first shell 101 and the first cover 101b are both made of high-strength ABS material. The first housing 101 is provided with a storage medium switching module 102, a first communication interface module, and a first control module 103, all of which are arranged on a circuit board. The first communication interface module is electrically connected to the monitoring device 4 and the shutdown docking device 3, respectively. The first communication interface module includes a first external connection port and a second external connection port located at the bottom of the first housing 101, and a USB3.0 module located on the circuit board. The first external connection port is electrically connected to the fourth external connection port, and the USB3.0 module is electrically connected to the second external connection port. The first external connection port and the second external connection port are both equipped with rubber waterproof wire sleeves for outdoor protection against rain and fog. The storage medium switching module 102 is used to store and output field monitoring data from the monitoring device 4. The first control module 103 is used to control the working state of the storage medium switching module 102, that is, to control the switching between the field monitoring mode and the data output mode. The first control module 103 is the main control chip.

[0041] Then refer to Figure 1-3The storage medium switching module 102 includes a base 102a and a rotating shaft 102b rotatably connected to the base 102a. The base 102a includes a high-precision servo and a connecting block. One end of the rotating shaft 102b is rotatably connected to the connecting block through a bearing, and the other end of the rotating shaft 102b is fixedly connected to the high-precision servo. A first storage medium 102c is also provided at one end of the rotating shaft 102b. The first data acquisition device 1 and the monitoring device 4 share the first storage medium 102c. The first storage medium 102c is an SD memory card. Among them, a first connecting seat 102d and a second connecting seat 102e for transmitting field monitoring data are respectively provided on both sides of the rotating shaft 102b. The first connecting seat 102d and the second connecting seat 102e are respectively arranged parallel to the rotating shaft 102b. A plurality of metal conductive sheets 102b1 are wound on the outer wall of the rotating shaft 102b at a certain interval along its length direction, which are used to electrically connect the metal conductive sheet 102b1 with the first connecting seat 102d or the second connecting seat 102e when the rotating shaft 102b rotates. The first connecting seat 102d and the second connecting seat 102e are both provided with a plurality of metal slots docking with the metal conductive sheet 102b1. The physical switching of the read and write permissions of the first storage medium 102c is realized by switching the metal slots of the metal conductive sheet 102b1 on the first connecting seat 102d and the second connecting seat 102e. Among them, nine grooves are provided on the rotating shaft 102b along its length direction, and the number of metal conductive sheets 102b1 is nine. The metal conductive sheets 102b1 are wound in the grooves and extend to the outside of the rotating shaft 102b to form a connecting portion. The metal slot of the first connecting seat 102d and the metal slot of the second connecting seat 102e both have nine gold fingers. The gold fingers have a raised portion and are connected to the connecting portion of the metal conductive sheet 102b1. The nine metal conductive sheets 102b1 are connected in series through soft multi-core wires and connected to the first storage medium 102c.

[0042] In this embodiment, the circuit board is also provided with an external wiring hub, a relay switch, and a power inlet. The external wiring hub is electrically connected to the first external wiring port, the relay switch, and the first connector 102d, respectively. The second connector 102e is electrically connected to the USB 3.0 module and reads data. The power inlet is electrically connected to the second external wiring port. The first data acquisition device 1 and the monitoring device 4 are connected via an 11-core wire. Nine of these wires are used for the VDD, VSS1, VSS2, DAT1, DAT0, CLK, CMD, CD / DAT3, and DAT2 connections of the first storage medium 102c. Two of these wires are connected to the relay switch as reserved functional lines. Given that the monitoring device 4 does not support SD card hot-swapping, the relay switch is connected to the power supply circuit of the monitoring device 4 via two wires. When the metal conductive sheet 102b1 of the rotating shaft 102b rotates to the metal slot of the first connecting seat 102d, the relay switch will disconnect the power for 3 seconds. At this time, the monitoring device 4 will be powered off and shut down. After 3 seconds, the power will be turned on again. The monitoring device 4 can then read and write to the first storage medium 102c normally. For monitoring devices 4 that support hot-swappable storage media, the above steps are skipped. The above 11-core wires are connected to the monitoring device 4 through an external wiring hub to form a multi-core wire. In the field monitoring mode, the first data acquisition device 1 is in a dormant state. The rotating shaft 102b will rotate the metal conductive sheet 102b1 to dock with the metal slot of the first connecting seat 102d, thereby transmitting the data of the monitoring module 403 to the first storage medium 102c through the fourth external wiring port, the first external wiring port, the external wiring hub, and the first connecting seat 102d in sequence. In the data output mode, the rotating shaft 102b will rotate the metal conductive sheet 102b1 to dock with the metal slot of the second connecting seat 102e, thereby transmitting the field monitoring data in the first storage medium 102c to the shutdown docking device 3 through the second connecting seat 102e, the USB3.0 module and the second external wiring port in sequence, and then further transmitting it to the second data acquisition device 2, realizing the physical switching of the read and write permissions of the first storage medium 102c.

[0043] Next reference Figure 1 、 7-11, the parking docking device 3 includes a parking platform 301. The parking platform 301 is generally rectangular in structure. A plurality of support legs 305 are provided at the bottom of the parking platform 301. The support legs 305 are used to support the parking platform 301 near the field monitoring position 6. The support legs 305 are retractable support legs with universal joints. The universal joints are fixed at both ends of the retractable support legs. One universal joint is connected to the parking platform 301, and the other universal joint is connected to the field monitoring position 6. There are four support legs 305, each fixed at the four corners of the bottom of the parking platform 301. By adjusting the rotation angle and direction of the universal joints and the extension and retraction of the support legs 305, the position of the parking platform 301 at the field monitoring position 6 can be adjusted to adapt to different field environments. The ends of the retractable support legs can also be caliper structures to achieve universal rotation.

[0044] Parking platform 301 is provided with a through slot 301a for parking drone 5. Slot 301a runs along the length of platform 301 and has an inverted conical cross-section, i.e., it has two opposing inclined surfaces. The angle formed between these inclined surfaces and platform 301 is 30-60°, preferably 45°. Slot 301a forms an open opening at the top and bottom of platform 301. The opening at the top of platform 301 is used to receive drone 5 into slot 301a, while the opening at the bottom utilizes the airflow generated by drone 5 to remove any foreign matter such as fallen leaves and dust, while effectively preventing water accumulation. There are slide grooves 301a1 on both sides of the upper part of the through groove 301a. The two slide grooves 301a1 are roughly parallel to the length direction of the through groove 301a. A blocking rod 302 for moving the drone 5 along the length direction of the through groove 301a is slidably provided in the slide groove 301a1. The blocking rod 302 is located in the two slide grooves 301a1. When the drone 5 is parked in the through groove 301a, the position of the drone 5 in the through groove 301a can be fine-tuned by moving the blocking rod 302, thereby enabling the second data acquisition device 2 mounted on the bottom of the drone 5 to be physically docked with the parking docking device 3. Among them, a screw 302a is provided on the outer side of the slide 301a1 along its length direction, which is threadedly connected to one end of the blocking rod 302. One end of the screw 302a is rotatably connected to the outer side of the parking platform 301, and the other end of the screw 302a extends to the inside of the box 304 and is connected to the motor 304c arranged inside the box 304. The slide 301a1 is a rectangular strip groove, and the cross-section of the blocking rod 302 is square. One end of the blocking rod 302 has a threaded hole, and the blocking rod 302 is threadedly connected to the screw 302a through the threaded hole. The rotation of the screw 302a is driven by the motor 304c, and the blocking rod 302 is driven to slide along the length direction of the slide 301a1. The position of the drone 5 is adjusted by the movement of the blocking rod 302.

[0045] Continue to refer to Figure 7 and Figure 11A box 304 is provided on one side of the parking platform 301, and a communication transmission mechanism 304a and a power supply 304b are provided inside the box 304. The communication transmission mechanism 304a is provided with a first LoRa module 304a1, a third communication interface module and a USB3.0 module. The first LoRa module 304a1, the third communication interface module and the USB3.0 module are all arranged on a circuit board. The third communication interface module includes a third external wiring port and a first magnetic interface 301b. The third external wiring port is located on the outside of the box 304 and is electrically connected to the USB3.0 module and the second external wiring port respectively. The first magnetic interface 301b is located on an inner side wall of the through slot 301a. The power supply 304b is electrically connected to the communication transmission mechanism 304a and the first data acquisition device 1 respectively. The various components in the box 304 are connected to the first data acquisition device 1 via optical fiber connecting lines and DC 12V conductive lines. The optical fiber connecting lines are used for high-speed, low-loss wired data transmission. The power supply 304b supplies power to the first data acquisition device 1, the motor 304c and the communication transmission mechanism 304a via the DC 12V conductive lines.

[0046] Roller assemblies 303 are located on both sides of the lower portion of the through-slot 301a to assist in adjusting the movement of the second data acquisition device 2. The roller assembly 303 includes a plurality of vertical rollers 303a and a plurality of transverse rollers 303b spaced at regular intervals along the length of the through-slot 301a. The transverse rollers 303b are positioned above the vertical rollers 303a. Together, these rollers form a movable space for accommodating and adjusting the second data acquisition device 2 to a horizontal position. When the drone 5 is slightly misaligned within the through-slot 301a, the motor 304c drives the lever 302 to move the drone 5, driving the second data acquisition device 2 to move to a horizontal position via the transverse rollers 303b, where it then snaps into the movable space. The vertical rollers 303a then assist in further movement until the second magnetic interface 201a is magnetically connected to the first magnetic interface 301b of the communication transmission mechanism 304a, ensuring smooth data transmission.

[0047] Then refer to Figure 1 、 4and 7. The second data acquisition device 2 includes a second shell 201, which is detachably connected to the bottom of the drone 5. The top of the second shell 201 is open and is provided with a second cover 201d. The second shell 201 and the second cover 201d are both made of high-strength ABS material. The top of the second cover 201d is provided with a second clip 205, and the bottom of the drone 5 is provided with a first clip 501 that cooperates with the second clip 205. Specifically, the second clip 205 includes a support and a slot 205a provided at the top of the support. The first clip 501 includes a flat plate and a card block 501a provided at the bottom of the flat plate. The card block 501a is carded together with the card slot 205a to fix the drone 5 and the second data acquisition device 2, and the top of the flat plate and the bottom of the drone 5 are rotatably connected together by a rotating rod to ensure that the second data acquisition device 2 can be in a horizontal position even if the drone 5 is tilted, so as to better access the parking docking device 3. The second housing 201 is provided with LoRa antennas 201b and heat dissipation holes 201c on both sides. The heat dissipation holes 201c can fully utilize the airflow generated by the drone 5 during flight to effectively dissipate the heat generated during the operation of the second data acquisition device 2. The second housing 201 is internally provided with a second LoRa module 202, a second communication interface module, a second control module 203, and a second storage medium 204. The second communication interface module includes a second magnetic interface 201a located on the front side of the second housing 201. The second magnetic interface 201a is magnetically connected to the first magnetic interface 301b. The second storage medium 204 is used to store field monitoring data from the first data acquisition device 1, and the second control module 203 is used to control the second storage medium 204 to read data.

[0048] Among them, the first LoRa module 304a1 is connected to the second LoRa module 202 for communication, and is used to control the working mode of the first data acquisition device 1 when sensing that the second data acquisition device 2 is far away from or close to the shutdown docking device 3. When sensing that the second data acquisition device 2 is far away, the first data acquisition device 1 is in the field monitoring mode. At this time, the first data acquisition device 1 and the shutdown docking device 3 are in low power consumption mode. Due to the advantage of low power consumption of the LoRa module, only the first LoRa module 304a1 is in working state. When the first LoRa module 304a1 is connected to the shutdown docking device 3 via point-to-point wireless communication, the first data acquisition device 1 is in the field monitoring mode. Upon sensing the presence of the second LoRa module 202, the communication transmission mechanism 304a and the first data acquisition device 1 are awakened to start working. After the drone 5 lands in the through slot 301a of the parking platform 301, the first LoRa module 304a1 sends an instruction to the second LoRa module 202, triggering the motor 304c to drive the lever 302 to slide, thereby pushing the drone 5 and the second data acquisition device 2 toward the communication transmission mechanism 304a until the second data acquisition device 2 and the communication transmission mechanism 304a complete magnetic docking. At this time, the first data acquisition device 1 switches to data output mode.

[0049] Continue to refer to Figure 7 At least one elastic member 201e is also disposed on the front side of the second housing 201. This elastic member 201e is located above the second magnetic interface 201a. When the first magnetic interface 301b and the second magnetic interface 201a are magnetically connected, the elastic member 201e, under the pressure of the barrier 302, abuts against the inner wall of the through-slot 301a, generating a certain preload force. When data transmission is complete and the second data acquisition device 2 needs to be separated from the communication transmission mechanism 304a, the first LoRa module 304a1 simply sends a command to the second LoRa module 202, causing the motor 304c to control the barrier 302 to slide away from the drone 5. At this point, the preload force of the elastic member 201e is released, generating a rebound force, thereby separating the second magnetic interface 201a from the first magnetic interface 301b, preparing the drone 5 for takeoff.

[0050] In an embodiment not shown, the upper surface of the parking platform 301 is covered with multiple solar panels, which are electrically connected to the power supply 304b. The solar panels are used to store the generated electrical energy in the power supply 304b to provide power for the parking docking device 3 and the first data acquisition device 1.

[0051] A method for collecting data from a field non-network monitoring device system using a drone, the method comprising:

[0052] Collecting field monitoring data from the vicinity of a field monitoring location 6 using a monitoring device 4;

[0053] When the shutdown docking device 3 senses that the second data acquisition device 2 is moving away from or approaching, the first data acquisition device 1 is controlled to switch the working mode;

[0054] When the second data acquisition device 2 is away from the shutdown docking device 3, the first data acquisition device 1 is in field monitoring mode, receiving and storing field monitoring data from the monitoring device 4. In this mode, both the first data acquisition device 1 and the shutdown docking device 3 are in a dormant state. The read and write permissions of the first storage medium 102c in the first data acquisition device 1 are switched to the monitoring device 4 via the storage medium switching module 102, and the monitoring data generated by the monitoring device 4 is stored in the first storage medium 102c.

[0055] When the second data acquisition device 2 approaches and is connected to the docking station 3, the first data acquisition device 1 enters data output mode, transmitting the field monitoring data stored in the first data acquisition device 1 to the second data acquisition device 2. In this mode, when the second data acquisition device 2, mounted on the drone 5, flies within 50 meters above the docking station 3, the second data acquisition device 2 searches for the first LoRa module 304a1 signal via the second LoRa module 202 to establish a line communication connection, waking up the docking station 3 and the second data acquisition device 2. The drone 5 then lands on the docking station 3. The second LoRa module 202 then sends a command to the first LoRa module 304a1 to activate the motor 304c, which drives the lever 302 to adjust the position of the drone 5, physically connecting the second data acquisition device 2 and the docking station 3. This completes the docking of the first and second magnetic interfaces. The first data acquisition device 1 is awakened by the shutdown docking device 3, and the read and write permissions of the first storage medium 102c built into the first data acquisition device 1 are switched from the monitoring device 4 to the first data acquisition device 1 via the storage medium switching module 102. The first storage medium 102c within the first data acquisition device 1 losslessly transmits data to the shutdown docking device 3 via an optical fiber, which then transmits the data to the second storage medium 204 within the second data acquisition device 2. Specifically, after the first data acquisition device 1 is awakened and enters data output mode, the main control chip of the first control module 103 controls the read and write permission switching shaft 102b of the first storage medium 102c to rotate the metal conductive sheet 102b1 from the metal slot of the first connecting socket 102d to the metal slot of the second connecting socket 102e, thereby switching the read and write permissions of the first storage medium 102c. The periodically compressed data within the first storage medium 102c is then transmitted sequentially through the USB 3.0 module and the communication transmission mechanism 304a to the second storage medium 204.

[0056] After all data transmission is completed, the shutdown docking device 3 and the second data acquisition device 2 are disconnected by pulling the barrier rod 302 and under the action of the elastic member 201e, and the read and write permissions of the first storage medium 102c built into the first data acquisition device 1 are switched back to the monitoring device 4 to continue collecting field monitoring data. Then the drone 5 takes off from the shutdown docking device 3 and heads to the next target location. Finally, the drone is controlled to return to get the compressed package file. After decompression, the original file generated by the monitoring device 4 can be obtained, thereby performing high-throughput data collection on the field network-free monitoring device 4 and ensuring lossless transmission of data.

[0057] For the above-mentioned processes of "compressing package data" and "decompression", the first data acquisition device 1 regularly packages and compresses the data transmitted by the monitoring device 4 to the first storage medium 102c. Since the data generated by the monitoring device 4 may be too fragmented and the data volume is large, if packaging and compression are not performed, the drone 5 will spend a lot of time transmitting data and verifying the integrity of the file when collecting data. If the data is automatically packaged and compressed once a week, the drone collects data once a month, and only 4-5 compressed packages need to be collected each time, saving data collection time. This is a relative optimization for the drone's flight time and improves data collection efficiency.

[0058] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be considered as equivalent replacement methods and are included in the scope of protection of the present invention.
