Technical Field

[0001] The utility model relates to the technical field of agricultural planting, in particular to a monitoring device for agricultural planting. Background Art

[0002] With the progress of the times and the continuous development of science and technology, agricultural planting is gradually moving towards intelligence, and real-time monitoring of the growth environment of crops is conducive to intelligent planning of crop planting and to increasing crop yields. However, most of the existing intelligent agricultural monitoring devices are exposed to the outside, which is easily affected by the external environment and damaged, affecting their use. At the same time, the equipment adopts a fixed installation method, which is not conducive to maintenance and relocation, and the detection device has poor flexibility and cannot perform comprehensive detection, which brings inconvenience to use.

[0003] With the advancement and development of drone technology, the application scope of drones in agriculture is becoming increasingly wide. Drones used in agriculture can spray pesticides and monitor pests and diseases. At present, most drones used for monitoring install various sensor devices on the outside of the drone. This makes the sensor devices susceptible to collision with external objects when in use or idle. For example, if they collide with birds flying in the air during flight, it is easy to cause damage to the sensor equipment. In addition, the sensor equipment is exposed to the outside for a long time and is prone to dust adhesion, which is bound to affect the performance of some sensors (such as visual sensors). Utility Model Content

[0004] Therefore, in order to solve the above-mentioned shortcomings, the utility model provides a monitoring device for agricultural planting. By arranging a linear telescopic device on the unmanned aerial vehicle, the monitoring device can push the sensor equipment out of the unmanned aerial vehicle during the monitoring process, thereby realizing the monitoring of the external environment and crops. During the flight and when idle, the sensor equipment is pulled back into the unmanned aerial vehicle, thereby protecting the internal sensor equipment from being damaged by external force impact, and preventing dust from adhering to the inside to a certain extent, thereby ensuring the quality of monitoring.

[0005] The utility model is implemented by constructing an agricultural planting monitoring device, including an unmanned aerial vehicle;

[0006] A controller, disposed inside the unmanned aerial vehicle;

[0007] A plurality of sensor devices are arranged at the bottom or inside of the unmanned aerial vehicle in a retractable manner;

[0008] The linear telescopic device is arranged on the top of the unmanned aerial vehicle and keeps the telescopic end inserted into the interior of the unmanned aerial vehicle to drive the sensor equipment to rise and fall.

[0009] Specifically, the unmanned aerial vehicle includes a bottom plate, a top plate, a connecting arm and a propeller. The bottom plate and the top plate are arranged in parallel and connected together by connecting arms at four corners to form a cavity area. One end of the connecting arm connects the bottom plate and the top plate, and the other end extends to the outside and a rotatable propeller is arranged on the top of the outer end. The controller is fixed in the cavity area formed between the bottom plate and the top plate.

[0010] According to the technical features described in the previous paragraph, the specific structure of the unmanned aerial vehicle is set to facilitate driving the sensor equipment for flight monitoring, while also ensuring that there is a cavity area inside the unmanned aerial vehicle to facilitate the placement of controllers and sensor equipment, etc.

[0011] Specifically, a driver is further provided in the cavity area between the bottom plate and the top plate, a power source is provided in the driver, and the driver maintains power transmission with the propeller.

[0012] According to the technical features described in the previous paragraph, the driver and power supply are provided to facilitate the flight of the unmanned aerial vehicle, thereby enabling it to move freely in the air for easy monitoring.

[0013] Specifically, the linear telescopic device is arranged at the center of the top plate and keeps the telescopic end passing through the top plate and the bottom plate. A sensor device is arranged at the telescopic end of the linear telescopic device, and the sensor device is used to monitor the external environment.

[0014] According to the technical features described in the previous paragraph, placing the linear telescopic device and the sensor equipment at the center position ensures the stability of the entire device and facilitates flight.

[0015] Specifically, the sensing device includes a distance sensor arranged at the bottom and a visual sensor and a temperature sensor connected in sequence.

[0016] According to the technical features described in the previous paragraph, the type of sensor is set to facilitate real-time shooting and monitoring of the external environment, so that the monitoring personnel can remotely control and directly view the real-time monitoring data for timely processing. The distance sensor is set to ensure that when the unmanned aerial vehicle lands to the maximum distance, the controller controls the linear telescopic device to retract and pull the sensor equipment back into the unmanned aerial vehicle, thereby preventing the sensor equipment from directly colliding with the ground.

[0017] Specifically, the sensing device, the driver and the linear telescopic device are respectively connected to the controller through lines, and a wireless communication unit is also provided in the controller.

[0018] According to the technical features described in the previous paragraph, the wireless communication unit is provided to facilitate remote control by monitoring personnel, and also to facilitate remote viewing of real-time monitoring data or images, etc.

[0019] The utility model has the following beneficial effects:

[0020] The monitoring device is equipped with a linear telescopic device on the unmanned aerial vehicle. During the monitoring process, the sensor equipment can be pushed out of the unmanned aerial vehicle, thereby realizing the monitoring of the external environment and crops. During the flight and when idle, the sensor equipment can be pulled back into the unmanned aerial vehicle to protect the internal sensor equipment from being damaged by external impact, and to a certain extent prevent dust from adhering to the inside, thereby ensuring the quality of monitoring.

[0021] Compared with existing fixed monitoring devices and self-propelled monitoring devices, this monitoring device can fly to crops at various locations in the field through an unmanned aerial vehicle for monitoring, which is convenient, fast, simple and efficient. Fixed monitoring devices can only monitor crops in a designated area. Although self-propelled monitoring devices can monitor a larger area than fixed monitoring devices, due to the influence of crops in the field, it is not convenient to monitor the crops inside the field, and it is easy to collide with crops during movement.

[0022] Compared with existing monitoring drones, this monitoring device can retract the sensor equipment into the drone to prevent damage to the sensor equipment caused by collision with external objects during flight, and also avoid dust adhering to the sensor equipment and affecting the monitoring performance.
