Geographic information data collector and geographic information collection system

Abstract

The utility model provides a geographic information data collector and a geographic information collection system. The geographic information data collector includes an unmanned aerial vehicle (UAV) and a shooting component. The UAV is provided with electric energy through a battery to supply the flight mechanism to drive the main body to fly. A storage cavity is provided on the main body for accommodating a camera. During normal flight surveying, the lifting mechanism drives the camera to extend from the bottom of the storage cavity, and can shoot and record the geographical information such as farmland, houses, and woodlands on the ground. When it is necessary to return for charging, the lifting mechanism drives the camera to rise so that the camera can be retracted into the storage cavity. With this arrangement, the camera will not occupy the space under the UAV body when it is idle. After the UAV lands, the distance between the battery and the parking platform is reduced, which is conducive to wireless charging or metal contact charging. Wireless charging or metal contact charging can both achieve unmanned charging, making the equipment more automated.

Description

Technical Field

[0001] The utility model belongs to the technical field of rail transportation, and in particular relates to a geographic information data collector and a geographic information collection system. Background Art

[0002] Geographic information refers to information related to spatial geographical distribution, representing the inherent data, quality and distribution characteristics of surface objects and the environment. In urban and rural construction, land and resources utilization, and environmental protection, geographic information data collection is one of the most important links. By collecting geographic information data, management departments can clearly understand the utilization of land resources. The devices used for geographic information data collection can be divided into two types. One is a ground instrument, such as a surveying instrument. The surveying instrument is supported by a fixed tripod. After the operator moves the surveying instrument to the surveying site, the tripod is opened and the surveying instrument is installed on the tripod for surveying. This method requires frequent movement of positions and is time-consuming and labor-intensive. The other is drone surveying, which is efficient, convenient and fast by installing a camera on the drone to shoot the ground.

[0003] When using drones to collect geographic information data, drones need to be charged after each return due to their short flight time. There are three ways to charge drones. One is to connect the power supply and the drone's battery through a power cord. The other is to set metal charging contacts under the drone battery and metal power contacts on the drone landing platform. After the drone lands, the charging contacts and power contacts are connected to achieve circuit connection. Another method is to set a wireless charging module on the drone landing platform, which is more convenient. Since the camera of a drone is generally installed under the drone in the prior art, there is a certain distance between the charging position and the power supply. Metal contacts and wireless charging are not applicable. Generally, it is necessary to manually plug and unplug the charging plug, and the operation is relatively cumbersome. Utility Model Content

[0034] Please also read Figures 1 to 4 , the geographic information data collector 1 and the geographic information collection system provided by the embodiment of the utility model are described below.

[0035] See also Figures 1 to 4 In the first aspect, the embodiment of the utility model provides a geographic information data collector 1, including a drone 10 and a shooting component 20. The drone 10 includes a body 11, a flight mechanism 12 and a battery 13. The bottom of the body 11 is provided with a receiving cavity 111. The battery 13 is arranged in the body 11 and is located on one side of the receiving cavity 111. The shooting component 20 includes a camera 21 and a lifting mechanism 22. The camera 21 has a working state and an idle state. When in the working state, the camera 21 is located below the body 11 and corresponds to the receiving cavity 111 up and down. When in the idle state, the camera 21 is accommodated in the receiving cavity 111. The lifting mechanism 22 is arranged in the body 11 and is used to drive the camera 21 to rise and fall, so that the camera 21 switches between the working state and the idle state.

[0036] Compared with the prior art, the geographic information data collector 1 provided by the embodiment of the utility model has the following beneficial effects:

[0037] The geographic information data collector 1 provided by the embodiment of the utility model includes an unmanned aerial vehicle 10 and a shooting component 20. The unmanned aerial vehicle 10 provides electric energy through a battery 13 to supply the flight mechanism 12 to drive the main body 11 to achieve flight. A receiving cavity 111 is provided on the main body 11 for accommodating the camera 21. During normal flight surveying, the lifting mechanism 22 drives the camera 21 to extend from the bottom of the receiving cavity 111, and can shoot and record the geographical information such as farmland, houses, and woodlands on the ground. When it is necessary to return for charging, the lifting mechanism 22 drives the camera 21 to rise, so that the camera 21 can be retracted into the receiving cavity 111. In this way, on the one hand, when the camera 21 is in an idle state, it will not occupy the space under the main body 11 of the unmanned aerial vehicle 10. After the unmanned aerial vehicle 10 lands, the distance between the battery 13 and the parking platform 30 is reduced, which is helpful to realize wireless charging or metal contact charging. Wireless charging or metal contact charging can realize unmanned charging, making the equipment more automated. On the other hand, the camera 21 is in the accommodating chamber 111 when not in use. When the drone 10 falls accidentally during the return journey, the accommodating chamber 111 plays a protective role, and the expensive camera 21 is not easily damaged, which helps to reduce property losses.

[0038] In the embodiment of the utility model, the drone 10 includes a body 11, a flight mechanism 12 and a battery 13. The drone 10 can directly select existing products on the market. Considering that the existing drones 10 on the market may not have a receiving cavity 111, a receiving component with a receiving cavity 111 can be additionally installed on the shell of the drone 10 to form the body 11. The receiving component is made by screw connection, welding, bonding, etc. In order to reduce weight, the body 11 is generally made of lightweight materials.

[0039] The flight of the drone 10 can be achieved by remote control. The battery 13 is used to supply power to the flight mechanism 12, the camera 21, the remote sensing module, the control system, etc. The battery 13 can be a lithium battery 13 with a high energy density. The battery 13 can be charged by a charging plug (such as a USB, type-c interface plug), or by metal contact charging (a charging metal contact 131 needs to be set under the battery 13. There are generally two contacts, which are used to connect the positive and negative poles respectively). Wireless charging can also be used. It should be noted that contact charging has high requirements on the landing accuracy of the drone 10. When an offset occurs, poor charging contact may result. The wireless charging drone 10 only needs to land on the parking platform 30 equipped with a wireless charging module.

[0040] The shooting component 20 includes a camera 21 and a lifting mechanism 22. The camera 21 can be directly selected from existing cameras on the market to shoot ground geographical conditions such as farmland, buildings, factories, woodlands, green areas, etc., so that relevant departments can promptly detect illegal land use situations.

[0041] When conducting geographic information surveying and mapping, the camera 21 used has strong imaging capabilities and is expensive. Once the drone 10 falls, it is very likely to cause damage to the camera 21. For this reason, the utility model designs the camera 21 to be retractable. Through a preset program, when the drone 10 is out of control, the lifting mechanism 22 automatically operates to retract the camera 21 into the accommodating cavity 111, protecting the camera 21 from damage and reducing property losses.

[0042] See also Figure 1 and Figure 2 In some possible embodiments, the body 11 is provided with a plurality of cantilevers 112 along its circumference, the flight mechanism 12 includes a plurality of blades 122 and a plurality of motors 121, the blades 122 correspond to the cantilevers 112 one by one, the motor 121 is used to drive the corresponding blades 122 to rotate, and the battery 13 is electrically connected to the motor 121. In practical applications, four or more blades 122 are generally provided as needed. In order to achieve a stable landing, the body 11 may also be provided with a plurality of legs along its circumference. When no legs are provided, the bottom of the battery 13 may also be supported, and after landing, the bottom of the battery 13 is attached to the parking platform 30 for easy charging.

[0043] See also Figure 1 and Figure 2 In some possible embodiments, a charging metal contact 131 is provided at the bottom of the battery 13, and a corresponding discharge metal contact is provided on the parking platform 30. When the drone 10 lands, the charging metal contact 131 and the discharge metal contact on the parking platform 30 are connected, and charging can be achieved. In order to prevent poor contact, magnets are buried at the corresponding positions of the charging metal contact 131 and the parking platform 30, and the two can generate magnetic attraction, so that the metal contacts are closely abutted and smoothly connected.

[0044] In some possible embodiments, the lifting mechanism 22 is a vertically arranged electric telescopic rod, which can be extended and retracted when powered, thereby driving the camera 21 to move up and down.

[0045] In some possible embodiments, the lifting mechanism 22 includes a motor and a rack capable of driving the motor to move up and down, the motor is arranged on the main body 11, and the output shaft of the motor is provided with a gear; the rack is vertically slidably arranged on the inner wall of the accommodating cavity 111, the rack is meshed with the gear, and the bottom of the rack is connected to the camera 21.

[0046] In this embodiment, the lifting mechanism 22 includes a motor, a gear and a rack. The motor is arranged on the body 11 and drives the rack to move up and down through the gear. The lower part of the rack is connected to the camera 21, so that the camera 21 can move up and down.

[0047] See also Figures 1 to 3 In some possible embodiments, the lifting mechanism 22 is a scissor-type lift, and the lower end of the scissor-type lift is connected to the camera 21. Compared with the structure of an electric telescopic rod or a rack, the scissor-type lift occupies less space and is easy to implement. The structure of the scissor-type lift belongs to the prior art and will not be described in detail here.

[0048] See also Figures 1 to 3 In some possible embodiments, the accommodating cavity 111 passes through the main body 11 from top to bottom, and a support plate 14 is provided above the accommodating cavity 111 . The support plate 14 is connected to the main body 11 through a connecting column 15 , and the lifting mechanism 22 is provided on the support plate 14 .

[0049] In order to avoid that the vertical space is insufficient to accommodate the scissors-type lift and the camera 21, the accommodating cavity 111 in this embodiment passes through the main body 11 from top to bottom, the support plate 14 is lifted to a certain height through the connection, and the lifting mechanism 22 is arranged on the support plate 14. The vertical space of the accommodating cavity 111 is increased, which can ensure that the camera 21 and the lifting mechanism 22 are smoothly accommodated in the accommodating cavity 111.

[0050] In some possible embodiments, the inner wall of the accommodating cavity 111 is provided with an anti-collision buffer layer, which can protect the internal camera 21 in the event of an accidental crash. The anti-collision buffer layer can be a flexible material such as foam, rubber, sponge, etc.

[0051] See also Figure 4 In the second aspect, the embodiment of the utility model also provides a geographic information collection system, including a parking platform 30 and a geographic information data collector 1, the geographic information data collector 1 is provided with one or more, and the parking platform 30 is provided with a contact charging module or a wireless charging module.

[0052] In some possible embodiments, the charging module is a wireless charging module that can wirelessly charge the battery 13 .

[0053] The geographic information collection system provided by the utility model adopts the geographic information data collector 1 in any of the above embodiments, and realizes automatic charging of the drone 10 through the parking platform 30, which helps to reduce the labor burden of personnel and improve the automation level of geographic information collection.

[0054] It can be understood that the various parts in the above-mentioned embodiments can be freely combined or deleted to form different combination embodiments. The specific contents of each combination embodiment will not be repeated here. After this description, it can be considered that the utility model specification has recorded various combination embodiments and can support different combination embodiments.
