Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of measuring tools, and particularly relates to a detection system for the remaining amount inside a granary. Background Art
[0002] At present, the detection of the remaining amount inside a granary mostly relies on manual visual inspection or simple sensor devices, and there are the following problems: the detection accuracy is not high, it is difficult to accurately grasp the inventory situation in real time; manual detection is time-consuming and laborious, with low efficiency; there is a lack of automated and intelligent management and it cannot meet the needs of modern warehousing; there is no data storage function for the inventory situation and it is impossible to obtain the storage data of the granary at any time and place; for large granaries, it is difficult to estimate the remaining amount, which is likely to cause food waste or management omissions; when the surface of the stored grain inside the granary is uneven, it will lead to a situation where the measured volume does not match the actual volume of the object. Summary of the Invention
[0003] In view of the above problems in the prior art, the utility model provides a detection system for the remaining amount inside a granary, and its technical solution is: it includes a granary body, a first rotating bracket is arranged inside the granary body, the first rotating bracket is connected to a second rotating bracket, the second rotating bracket is in transmission connection with an electromagnetic rudder, and an ultrasonic sensor is fixedly arranged below the electromagnetic rudder. The first rotating bracket, the second rotating bracket, the electromagnetic rudder and the ultrasonic sensor form a detection device.
[0004] As a preferred solution, the ultrasonic sensor is used to collect the height, density and three-dimensional point cloud parameters of the grain pile inside the granary body.
[0005] As a preferred solution, the first rotating bracket is arranged at the top of the inner wall of the granary body.
[0006] As a preferred solution, a movable connection method is adopted between the first rotating bracket and the second rotating bracket.
[0007] As a preferred solution, the height, density and three-dimensional point cloud parameters collected by the ultrasonic sensor are transmitted to a control system through a data transmission module for processing.
[0008] Working Principle of the Utility Model:
[0009] The ultrasonic sensor works based on the principle of sound wave reflection. It emits high-frequency sound waves beyond the range of human hearing (usually above 20 kHz). These sound waves are reflected back after encountering obstacles and are received by the sensor. By measuring the total time from the emission to the reception of the sound wave and combining the propagation speed of the sound wave in the air, the distance to the obstacle can be calculated. The formula is as follows:
[0010] .
[0011] Where the distance is the distance from the ultrasonic emission point to the measurement point of the grain pile, the sound speed is 343 m / s, and the time difference is the total time for the sound wave from emission to reception; since the sound speed is affected by temperature, in summary, ultrasonic waves are suitable for short-distance detection, especially for detecting the remaining amount in the granary. After the system obtains the position information and point cloud data of the measurement position, it preprocesses the three-dimensional point cloud data, including denoising, filtering, coordinate transformation, etc. Using the point cloud data, it reconstructs the three-dimensional surface model of the object through reverse engineering. According to the reconstructed object surface model, the volume of the object can be estimated by calculating the geometric volume. Volume segmentation is to divide the object into small volume units, then calculate the volume of each unit and sum them to obtain the volume of the entire object.
[0012] Advantages of the present utility model:
[0013] Compared with the traditional method, this system realizes non-contact, high-precision, real-time monitoring and historical data recording of the remaining amount inside the granary, greatly improving the warehousing management efficiency, reducing labor costs, ensuring food security, and is especially suitable for precise inventory control of large-scale and deep granaries.

[0020] Embodiment
[0021] As Figures 1-4 shown in the internal remaining amount detection system of the granary, including a granary body 2 and a detection device 1. A first rotating bracket 4 is arranged inside the granary body 2. The first rotating bracket 4 is connected to a second rotating bracket 5. The second rotating bracket 5 is in transmission connection with an electromagnetic rudder 6. An ultrasonic sensor 7 is fixedly arranged below the electromagnetic rudder 6. The first rotating bracket 4, the second rotating bracket 5, the electromagnetic rudder 6 and the ultrasonic sensor 7 form the detection device 1.
[0022] Further, the ultrasonic sensor 7 is used to collect the height, density, and three-dimensional point cloud parameters of the grain pile 1 in the barn body 2.
[0023] Further, the first rotating bracket 4 is arranged at the top of the inner wall of the barn body 2.
[0024] Further, an active connection mode is adopted between the first rotating bracket 4 and the second rotating bracket 5.
[0025] Further, the height, density, and three-dimensional point cloud parameters collected by the ultrasonic sensor 7 are transmitted to the control system through the data transmission module for processing.
[0026] When using the above system, the process is as follows: Rotate the second rotating bracket 5 to adjust the overall angle of the detection device 1 so as to facilitate the detection of contents at different heights and angles. Start the electromagnetic rudder 6. By adjusting the pulse width of the electromagnetic rudder 6, the movement direction and speed of the detection device 1 can be precisely controlled, thereby realizing the precise detection of the grain pile 3 in the granary; finally, use the ultrasonic sensor 7 to measure the height, density, and three-dimensional point cloud and other parameters of the grain pile 3 in the granary. The ultrasonic sensor 7 can obtain these data by transmitting and receiving ultrasonic signals, and transmit them to the control system for analysis and processing. Finally, a three-dimensional model of the remaining content in the barn is constructed, and the volume of the grain is designed and calculated through algorithms such as integration.
