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 field network-free monitoring equipment data using a drone. Background Art

[0002] The current data collection methods for field monitoring equipment mainly include the following: (1) traditional manual collection; (2) installing 4G / 5G and other network modules on the equipment to transmit data to the cloud server; (3) building wireless ad hoc network transmission; (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 the traditional manual collection method, in the wild without network environment, it is necessary to manually climb mountains and cross ridges to the device location to copy the data in the storage medium, which is costly and extremely dangerous; for the method of transmission through 4G / 5G, in the wild environment, there is almost no network coverage or the network is extremely unstable, and it is easy to lose data 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 climbing mountains and crossing ridges to the device location to copy data. The flight control platform controls the drone equipped with a data transmission module to fly to the vicinity of the device, and connects to the device point-to-point wirelessly, and copies the data of the device storage medium to the storage medium of the drone through wireless transmission, thereby realizing remote data collection at low cost.

[0003] However, existing drone data collection devices are all low-throughput data collection based on wireless communication. This transmission method is designed and developed for proprietary equipment and can only provide data transmission capabilities for one device. The code size of the transmission interface is relatively large, the implementation complexity is high, and the wireless transmission is extremely unstable. Its low-throughput data collection method can only transmit some very small amounts of data, such as text information, and cannot transmit large file data such as pictures and videos. The data collection efficiency is very low. Limited by the instability of wireless transmission and the ultra-low transmission speed, it is impossible to provide an efficient and stable high-throughput data collection solution for today's increasingly large field monitoring data. Therefore, how to develop a system that uses drones to collect data from field non-network monitoring equipment 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.

The first data acquisition device 1 and the monitoring device 4 share the first storage medium 102c, and the first storage medium 102c is an SD memory card. Among them, a first connecting socket 102d and a second connecting socket 102e for transmitting field monitoring data are respectively arranged on both sides of the rotating shaft 102b, and the first connecting socket 102d and the second connecting socket 102e are respectively arranged parallel to the rotating shaft 102b.

When the drone 5 is parked in the through slot 301a and the position is slightly deviated, the motor 304c can be used to drive the lever 302 to move the drone 5, drive the second data acquisition device 2 to move and adjust it to a horizontal position through the horizontal rollers 303b, and then get stuck in the moving space. Subsequently, the vertical rollers 303a will assist it to move further until the second magnetic interface 201a is magnetically connected with the first magnetic interface 301b of the communication transmission mechanism 304a, ensuring smooth data transmission.

[0044] Next refer to Figure 1 , 4and 7, the second data acquisition device 2 includes a second shell 201, the second shell 201 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 matches 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 through 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. There are LoRa antennas 201b and heat dissipation holes 201c on both sides of the second shell 201. The heat dissipation holes 201c can make full use of the airflow generated by the drone 5 during flight and effectively discharge the heat generated by the second data acquisition device 2 during operation. The second LoRa module 202, the second communication interface module, the second control module 203 and the second storage medium 204 are arranged inside the second shell 201. The second communication interface module includes a second magnetic interface 201a. The second magnetic interface 201a is located on the front side of the second shell 201. The second magnetic interface 201a is magnetically docked with the first magnetic interface 301b. The second storage medium 204 is used to store the 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.

[0045] The first LoRa module 304a1 is connected to the second LoRa module 202 for controlling 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 from the shutdown docking device 3, 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 the low power consumption mode. Due to the advantage of the low power consumption of the LoRa module, only the first LoRa module 304a1 is in the working state. When the first LoRa module 304a1 is connected to the shutdown docking device 3 through the point-to-point wireless mode When the presence of the second LoRa module 202 is sensed, 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 a command 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 to move toward the communication transmission mechanism 304a until the second data acquisition device 2 completes the magnetic docking with the communication transmission mechanism 304a. At this time, the first data acquisition device 1 switches to the data output mode.

[0046] Continue to refer to Figure 7 At least one elastic member 201e is also provided on the front side of the second housing 201. The 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 docked, the elastic member 201e abuts against the inner wall of the through slot 301a under the pressure of the blocking rod 302, generating a certain pre-tightening force. When the data transmission is completed and the second data acquisition device 2 needs to be separated from the communication transmission mechanism 304a, the first LoRa module 304a1 only needs to send a command to the second LoRa module 202, so that the motor 304c controls the blocking rod 302 to slide away from the drone 5. At this time, the pre-tightening force of the elastic member 201e is released, generating a rebound force, thereby realizing the separation of the second magnetic interface 201a from the first magnetic interface 301b, and preparing for the take-off of the drone 5.

[0047] 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.

[0048] A method for collecting data of a field non-network monitoring device system using a drone, the method comprising: Collecting field monitoring data from the vicinity of a field monitoring location 6 using a monitoring device 4; 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; When the second data acquisition device 2 is away from the shutdown docking device 3, the first data acquisition device 1 is in the field monitoring mode, receiving and storing the field monitoring data from the monitoring device 4. In this mode, the first data acquisition device 1 and the shutdown docking device 3 are both in a dormant state, and 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 through the storage medium switching module 102, and the monitoring data generated by the monitoring device 4 is stored in the first storage medium 102c.

[0049] And when the second data acquisition device 2 approaches and is connected to the parking docking device 3, the first data acquisition device 1 is in the data output mode, so that the field monitoring data stored in the first data acquisition device 1 is transmitted to the second data acquisition device 2. In this mode, when the second data acquisition device 2 is carried by the drone 5 and flies to within 50 meters above the parking docking device 3, the second data acquisition device 2 searches for the first LoRa module 304a1 signal through the second LoRa module 202 to establish a line communication connection, wake up the parking docking device 3 and the second data acquisition device 2, and then the drone 5 lands on the parking docking device 3, and then the second LoRa module 202 sends a command to the first LoRa module 304a1 to make the motor 304c work, and the motor 304c drives the lever 302 to adjust the position of the drone 5, and the second data acquisition device 2 and the parking docking device 3 are physically connected together, that is, the first magnetic interface and the second magnetic interface complete the docking. 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 through the storage medium switching module 102. The first storage medium 102c inside the first data acquisition device 1 transmits data to the shutdown docking device 3 losslessly through the optical fiber, and then the shutdown docking device 3 transmits the data to the second storage medium 204 inside the second data acquisition device 2. Specifically, after the first data acquisition device 1 is awakened and enters the data output mode, the main control chip of the first control module 103 controls the read and write permission switching rotating shaft 102b of the first storage medium 102c to rotate the metal conductive sheet 102b1 from the metal slot of the first connecting seat 102d to the metal slot of the second connecting seat 102e, so as to realize the switching of the read and write permissions of the first storage medium 102c, and start to transmit the periodic compressed package data in the first storage medium 102c to the second storage medium 204 through the USB3.0 module and the communication transmission mechanism 304a in sequence.

[0050] After all data transmission is completed, the shutdown docking device 3 and the second data acquisition device 2 are disconnected by pulling the baffle 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.

[0051] For the above-mentioned processes such as "compressing package data" and "decompression", the first data acquisition device 1 regularly packages and compresses the data transmitted from 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 packaged and compressed, 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.

[0052] 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 equivalent replacement methods and are included in the protection scope of the present invention.
