Description

Technical Field

[0001] The present invention relates to the technical field of urban ecological space research, and in particular to an urban ecological space identification system and method based on drone technology. Background Art

[0002] Ecological space refers to land space with natural attributes and the main function of providing ecological services or ecological products. It is a key area for maintaining regional ecological security and sustainable development. Carrying out ecological assessment and identifying ecological space can effectively curb ecosystem degradation and ensure regional land security, ecological environment security and resource security. In the process of urban ecological space identification, drones are generally used to mount collection equipment (such as cameras) to collect information about the city, and then the collected information is transmitted to a processing platform for processing to identify the city's ecological space.

[0003] During the flight of a drone, the drone's endurance is limited, and the city is relatively large, so the drone cannot collect all the city's information in one go. Therefore, the drone needs to land to replace the battery. However, the drone's landing area is random (when the drone's endurance is insufficient, it will choose a nearby ground to land). If the landing area is uneven, the bottom height of the drone's legs is fixed, causing the drone to easily roll over or even fall over after landing. Summary of the Invention

[0004] The purpose of the present invention is to provide an urban ecological space identification system and method based on drone technology, so as to solve the problem proposed in the above background technology that the landing area of ​​the drone is random and the landing area is uneven. Because the bottom height of the drone's support legs is fixed, the drone is prone to rollover or even tipping over after landing.

[0005] To achieve the above objectives, the present invention provides the following technical solutions: an urban ecological space identification system based on drone technology, comprising: a collection module, a transmission module, and a processing module; the collection module comprises: a drone body, a collection device disposed on the drone body, and two supporting legs disposed on both sides of the bottom of the drone body;

[0006] The support leg is provided with an installation box, and a moving part for moving up and down and an elastic part for pushing the moving part downward are slidably provided in the installation box, and an electromagnet for adsorbing the moving part is provided in the installation box, and a support rod is provided on the moving part, and the bottom end of the support rod extends to the bottom of the support leg and is connected to the support plate, and a pressure sensor is provided under the support plate, and a controller for receiving pressure sensor information and controlling the power off of the electromagnet is provided on the drone body; the drone body of the acquisition module is lifted into the air with the acquisition equipment to collect information of the city, and transmits the collected information to the processing module through the transmission module for processing, and identifies the urban ecological space. When the landing area of ​​the drone body is uneven, so that the pressure sensor on one support leg is not in contact with the ground, the controller receives the information, controls the electromagnet here to be powered off, and the elastic part pushes the moving part with the support rod and the support plate to move downward and contact the ground.

[0007] Preferably, there are several groups of pressure sensors, and the several groups of pressure sensors are evenly distributed on the bottom of the support plate and the support legs.

[0008] Preferably, a plurality of groups of slots are provided on the side wall of the support rod from top to bottom, and a limit block and an elastic element connected to the limit block are slidably inserted into the slot, and the bottom of the side wall of the limit block is an inclined surface.

[0009] Preferably, the drone body is provided with a counterweight and a driving mechanism for driving the counterweight to move closer to the supporting legs.

[0010] Preferably, the counterweight is a water tank, a water outlet is provided on a side wall of the water tank facing the support leg, a guide hole is provided on an inner side wall of the water tank and is coplanar with the water outlet, a guide member and a return spring connected to the guide member are slidably inserted into the guide hole, and a baffle for blocking the water outlet is provided at the end of the guide member;

[0011] The drone body is provided with two mounting blocks located on both sides of the water tank and on the same side as the two supporting legs respectively. The side of the mounting block facing the water tank is provided with an insert block aligned with the water outlet, and an opening is opened on the end of the insert block. The supporting legs are provided with a collection box, and the collection box is connected with a connecting pipe connected to the opening.

[0012] Preferably, the length of the insert is greater than the extended length of the water outlet.

[0013] Preferably, the drone body is provided with a warning device controlled by a controller.

[0014] As a preferred embodiment, a method for identifying urban ecological space based on drone technology, which utilizes an urban ecological space identification system based on drone technology, specifically comprises the following steps:

[0015] S1: The drone of the collection module takes off with the collection equipment and flies in the city, using the collection equipment to collect information about the city and transmit the collected information to the processing module through the transmission module;

[0016] S2: When the drone's flight time is insufficient, it descends. The landing area is uneven, causing one of the drone's legs to hang in the air. The pressure sensor on this leg is not in contact with the ground. Upon receiving this information, the controller de-energizes the electromagnet on this leg. Driven by the elastic element, the moving element, carrying the support rod and support plate, descends and makes contact with the ground. The drone's battery is then replaced, and the collection of city information continues.

[0017] S3: The processing module processes and analyzes the collected information to identify the urban ecological space.

[0018] Compared with the prior art, the beneficial effects of the present invention are: in this application, when the landing area of ​​the drone body is uneven and one of the legs of the drone body is suspended in the air, when the pressure sensor on this leg is not in contact with the ground, the controller receives the information and controls the electromagnet here to cut off the power, so that the moving part is restricted and disappears. Under the push of the elastic force of the elastic part, the moving part moves down with the support rod and the support plate and contacts the ground, preventing the drone body from rolling over and protecting the drone body and the collection equipment.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example 1

[0030] See also Figure 1 , an urban ecological space identification system based on drone technology, including: an acquisition module, a transmission module (communication equipment for transmitting information) and a processing module (the processing module can be a computer).

[0031] See also Figure 2 The acquisition module includes: a drone body 1, with supporting feet 3 installed on both sides of the bottom of the drone body 1, and a collection device 2 (such as a camera) installed on the drone body 1; a transmission module is installed on the drone body 1 and connected to the collection device 2, for transmitting the information collected by the collection device 2 to the processing module.

[0032] See also Figure 2 、 Figure 3 and Figure 5 , an installation box 5 is provided on the support leg 3, and a moving part 12 is slidably provided in the installation box 5 (the moving part 12 can move up and down inside the installation box 5), and an elastic part 13 is installed between the installation box 5 and the moving part 12, for pushing the moving part 12 downward; an electromagnet 15 is provided in the installation box 5, and the moving part 12 is made of magnetic metal material (metal material that can be magnetically adsorbed, such as iron), and the electromagnet 15 adsorbs the moving part 12, fixes it, and prevents it from moving; a support rod 14 is provided on the moving part 12, and the bottom end of the support rod 14 extends to the bottom of the support leg 3 and is connected to the support plate 4, and a pressure sensor 11 is provided under the support plate 4, and a controller (such as a central processing unit) is provided on the drone body 1, and the controller is connected to the pressure sensor 11 and the electromagnet 15.

[0033] In this embodiment, as a further optimization solution, please refer to Figure 2The drone body 1 is provided with an alarm 6 (which can be an LED light) controlled by a controller; after the drone body 1 lands, the pressure sensor 11 contacts the ground and detects pressure, which will be transmitted to the controller. The controller then turns on the power of the alarm 6, causing it to work and give a prompt, making it easier to find the drone body.

[0034] It should be noted that, during the process of the drone body 1 descending to replace the battery, when the area where the drone body 1 falls is uneven, causing one of the legs 3 of the drone body 1 to be suspended in the air, and the pressure sensor 11 on this leg 3 is not in contact with the ground, the controller receives the information and controls the electromagnet 15 here to cut off the power, so that the movable part 12 is restricted and disappears; under the push of the elastic force of the elastic part 13, the movable part 12 moves down with the support rod 14 and the support plate 4 and contacts the ground, ensuring that both legs 3 of the drone body 1 are in contact with the ground, preventing the drone body 1 from rolling over.

[0035] In this embodiment, as a further optimization solution, please refer to Figure 4 There are several groups of pressure sensors 11, and the groups of pressure sensors 11 are evenly distributed on the bottom of the support plate 4 and the support leg 3; pressure sensors 11 are evenly distributed on the bottom of each support leg 3 and support plate 4, and detection is performed through multiple pressure sensors 11 to ensure that the support plate 4 starts to move only when the support leg 3 is suspended in the air, thereby ensuring the accuracy of the detection.

[0036] In this embodiment, as a further optimization solution, please refer to Figure 8 Several groups of slots 141 are provided on the side wall of the support rod 14 from top to bottom, and limit blocks 143 are slidably inserted into the slots 141. Elastic elements 142 are installed between the slots 141 and the limit blocks 143, and the bottom of the side wall of the limit blocks 143 is an inclined surface; when the support rod 14 moves downward, the limit blocks 143 will move downward together, and the limit blocks 143 under the support legs 3 will be used to prevent the support rod 14 from automatically moving upward (the top of the limit blocks 143 is horizontal), thereby ensuring the stability of the support of the support plate 4 and reducing the chance of the drone body 1 rolling over.

[0037] Example 2

[0038] As an optimized solution, see 2 and Figure 4 A counterweight 7 is provided on the drone body 1, and a driving mechanism (such as an electric telescopic rod) is installed on the drone body 1. The moving end of the driving mechanism is connected to the counterweight 7; when one leg 3 is suspended in the air, the controller will control the driving mechanism to work, so that the counterweight 7 moves closer to the non-suspended leg 3, increasing the weight of the non-suspended side of the drone body 1, thereby further reducing the probability of the drone body 1 rolling over.

[0039] In this embodiment, as a further optimization solution, please refer to Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 and Figure 7 The counterweight 7 is a water tank 71 (water is filled in the water tank 71), and a water outlet 72 is provided on the side wall of the water tank 71 facing the support leg 3 (there are two water outlets 72, corresponding to the two support legs 3 respectively). Guide holes are provided on the inner walls of both sides of the water tank 71, and the two guide holes are on the same plane as the two water outlets 72. A guide member 74 is slidably inserted into the guide hole, and a return spring is installed between the guide hole and the guide member 74. A baffle 73 is provided at the end of the guide member 74 for blocking the water outlet 72; two mounting blocks 10 are provided on the drone body 1, and the two mounting blocks 10 are respectively located on both sides of the water tank 71 and on the same side as the two support legs 3 respectively; an insert block 16 is provided on the side of the mounting block 10 facing the water tank 71, The plug block 16 is aligned with the water outlet 72, and an opening 17 is provided on the end of the plug block 16; a collecting box 8 is provided on the support leg 3, and a connecting pipe 9 is connected to the collecting box 8, and the end of the connecting pipe 9 away from the collecting box 8 is connected to the opening 17; when the driving mechanism drives the counterweight 7 to move closer to one of the support legs 3, the counterweight 7 (water tank 71) contacts the mounting block 10 there, so that the plug block 16 is inserted into the water tank 71 through the water outlet 72; because the plug block 16 enters the inside of the water tank 71, it will push the baffle 73 to move, open the water outlet 72, and allow the water inside the water tank 71 to enter the inside of the collecting box 8 through the opening 17 and the connecting pipe 9, thereby increasing its gravity and lowering the center of gravity of the entire drone body 1 to prevent it from tipping over.

[0040] It should be noted that a pump (small) is installed inside the collection box 8 for transporting the water inside the collection box 8 to the inside of the water tank 71.

[0041] In this embodiment, as a further optimization solution, please refer to Figure 6 and Figure 7 , the length of the insert block 16 is greater than the length of the extension of the water outlet 72; when the insert block 16 is inserted into the interior of the water outlet 72, it can push the baffle 73 to move.

[0042] A method for identifying urban ecological space based on drone technology, which utilizes an urban ecological space identification system based on drone technology, specifically includes the following steps:

[0043] S1: The drone body 1 of the collection module takes off with the collection device 2 and flies in the city. It uses the collection device 2 to collect information about the city and transmits the collected information to the processing module through the transmission module.

[0044] S2: When the drone body 1 has insufficient battery life, the drone body 1 descends. If the landing ground is flat, both legs 3 are in contact with the ground, and the staff replaces the battery of the drone body 1; if the landing area is uneven, one leg 3 of the drone body 1 is suspended in the air, and the pressure sensor 11 on this leg 3 is not in contact with the ground. After receiving the information, the controller controls the electromagnet 15 on this leg 3 to cut off the power. Under the push of the elastic part 13, the moving part 12 moves down with the support rod 14 and the support plate 4 to contact the ground. Then the battery of the drone body 1 is replaced and the city information collection continues.

[0045] S3: The processing module processes and analyzes the collected information to identify the urban ecological space.

[0046] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
