Description

{Object surface height detection system}

The present invention relates to an object surface height detection system that detects the height of an object loaded inside a structure and generates an object loading rate inside the structure as a color map.

When loading objects onto vehicles, ships, airplanes, etc., it is important to understand the space available for each section of the storage space and the height of the loaded objects in order to load the objects evenly.

In the past, in order to determine the height of an object loaded in a storage space, there was the inconvenience of having to visually inspect the inside of the storage space or check the CCTV installed inside.

To solve this problem, there is a conventional technology that attaches an identification tag to each object stored in a storage space and installs a tag reader in the storage space. This can estimate the height of the loaded object based on the number of identification tags recognized by the tag reader, and thus determine the amount of space in the storage space. However, this technology does not identify the loading status of each object based on its height and size by the reader, making it difficult for the user to identify the exact loading rate by area inside the structure.

The purpose of the present invention is to enable a user to determine the height of an object loaded within a structure from outside the structure.

In addition, the present invention aims to enable a user to determine the loading rate by zone.

The purposes of the present invention are not limited to the purposes mentioned above, and other purposes and advantages of the present invention which are not mentioned can be understood by the following description, and will be more clearly understood by the embodiments of the present invention. In addition, it will be easily understood that the purposes and advantages of the present invention can be realized by the means and combinations thereof indicated in the claims.

The present invention provides a sensor that measures the height from the floor of the structure to the ceiling inside the structure, thereby enabling a user to determine the height of an object loaded inside the structure from outside the structure.

The present invention can enable a user to identify the loading rate by zone by generating a color map according to the loading rate by zone.

According to the present invention, by allowing a user to determine the height of an object loaded inside a structure from outside the structure, the inconvenience of the user having to directly visually check the inside of the structure can be reduced.

According to the present invention, the user can increase the loading rate by understanding the loading status by zone and evenly loading objects within the structure.

In addition to the effects described above, the specific effects of the present invention are described below together with specific details for carrying out the invention.

Referring to FIGS. 1 and 2, the object surface height detection system (100) according to the present invention may include a measuring device (110), a processor (120), and a memory (130). Meanwhile, the measuring device (110) may include a radar sensor (113), a motor (111), a jig (112), and a power supply (114). However, the object (400) surface height detection system (100) illustrated in FIGS. 1 and 2 is according to one embodiment, and its components are not limited to the embodiments illustrated in FIGS. 1 and 2, and some may be added or deleted as needed.

The measuring device (110) is equipped in the structure (300) and can measure the distance to an object (400) within the structure (300) by zone (r1, r2, r3, r4). More specifically, the measuring device (110) is equipped in the ceiling surface (310) of the structure (300) described below and can measure the distance to an object (400) located on the floor surface (320) of the structure (300).

The measuring device (110) may include a radar sensor (113) that measures distance and a motor (111) that rotates the radar sensor (113) in one direction.

One end of the motor (111) may be provided on the ceiling surface (310) of the structure (300), and the other end may be provided with a jig (112) capable of fixing a radar sensor (113) to the motor (111). When the motor (111) rotates the jig (112) in one direction about the vertical axis (115), the jig (112) and the radar sensor (113) may be rotated together. Accordingly, the motor (111) may rotate the radar sensor (113) in a horizontal direction.

The radar sensor (113) may be tilted at a predetermined angle based on the vertical axis (115). The radar sensor (113) may be rotated by the motor (111) and continuously measure the distance (d) to an object (400) located on the bottom surface (320) of the structure (300). At this time, the radar sensor (113) may use the mmwave band.

The power supply (114) can supply power to the motor (111) and the radar sensor (113).

Referring to FIGS. 3 and 4, the structure (300) includes an internal space of a rectangular solid, and an object (400) can be loaded into the internal space. The bottom surface (320) of the structure (300) is divided into a plurality of zones (r) arranged in a grid shape, and can include at least one square measurement region (G) that groups the plurality of zones (r). In the present embodiment, 2*2 zones (r) are grouped to form the measurement region (G), but the number of zones (r) to be grouped is not limited thereto and can be n*n. In addition, the number of zones (r) and measurement regions (G) can vary depending on the area of the bottom surface (320) of the structure (300).

Referring to FIG. 5, a plurality of measuring devices (110) are provided in a structure (300) to measure the distance (d) to an object (400) within the structure (300) by zone (r1, r2, r3, r4). The measuring devices (110) can be arranged by measurement area (G1, G2, G3, G4) on the ceiling surface (310) of the structure (300), and the arrangement interval (S) of the measuring devices (110) can be determined by the following mathematical formula.

( is the distance between the bottom surface of the above structure and the above measuring device, is the recognition range of the measuring device for the bottom surface of the above structure, is the angle of view of the above measuring device, is the margin)

At this time, when h is the distance from the ceiling of the structure (300) to the floor surface (320), hd can be the height of the object (400).

Referring to 6, a measuring device (110) is provided for each measuring area (G1, G2, G3, G4), and the measuring device (110) can measure the distance (d) to an object (400) while rotating in the direction of r1→r2→r3→r4.

The processor (120) can generate data based on the distance measured by the aforementioned measuring device (110) and transmit the data to the user terminal (200). The data includes any means capable of expressing the distance, and may include, for example, color, text, shapes, etc.

The processor (120) may include at least one physical element among application specific integrated circuits (ASICs), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), field programmable gate arrays (FPGAs), controllers, and micro-controllers to perform the operations described below.

In one example, the processor (120) may generate text data representing the distance (d) for each area (r1, r2, r3, r4) measured by the measuring device (110). That is, the processor (120) may calculate the height of an object (400) for each measurement area (G1, G2, G3, G4) and generate the same as text data (e.g., 1 m), or calculate the loading rate for each measurement area (G1, G2, G3, G4) and generate the same as text data (e.g., 10%, appropriate) and transmit the same to the user terminal (200).

In another example, the processor (120) can generate color information (C) representing the distance (d) of each zone (r1, r2, r3, r4) measured by the measuring device (110). At this time, the processor (120) can identify the color information (C) corresponding to the distance (d) of each zone (r1, r2, r3, r4) by referring to the memory (130) in which the color information (C) of each distance (d1, d2, d3, d4) is stored in advance.

Color information (C) corresponding to the distance between the radar sensor (113) and the object (400) may be stored in the memory (130) as shown in Table 1 below.

Distance between radar sensor and object Color information d1~d2 C1 d2~d3 C2 d3~d4 C3 d4~d5 C4

At this time, the distance value that crosses the boundary between the radar sensor (113) and the object (400) at a distance (d1 to d5) may correspond to the color information (C1 to C4) of the shorter distance. For example, if the distance between the radar sensor (113) and the object (400) is d2, the distance value range of d1 to d2 among the distance value ranges d1 to d2 and d2 to d3 may correspond to the color information C1.

Color information (C1, C2, C3, C4) can be contrasted with each other, such as white, blue, yellow, green, and red, so that the user can easily determine the distance between the radar sensor (113) and the object (400) for each zone (r1, r2, r3, r4). However, color information (C1, C2, C3, C4) for each distance (d1, d2, d3, d4) can be changed according to user settings.

Referring to FIG. 7, the processor (120) can generate a color map (500) including pixels (p) corresponding to each zone (r), apply color information (C) corresponding to the distance (d) of each zone (r) to the pixels (p), and transmit the color map (500) with the color information (C) applied to the user terminal (200).

The color map (500) can be generated with pixels (p) corresponding to the zones (r) of the floor surface (320). That is, the zones (r1, r2, r3, r4) of each group (G1, G2, G3, G4) of the floor surface (320) and the pixels (p1, p2, p3, p4) of each group (g1, g2, g3, g4) of the color map (500) can each correspond.

The user terminal (200) may be any device capable of wireless communication and may be equipped with a display capable of outputting a color map (500). For example, the user terminal (200) may include a kiosk, a smartphone, a laptop, a tablet, or a PC.

According to the present invention, by allowing a user to determine the height of an object loaded inside a structure from outside the structure, the inconvenience of the user having to directly visually check the inside of the structure can be reduced.

In addition, according to the present invention, there is an effect of increasing the loading rate by allowing the user to grasp the loading status by zone and load objects evenly within the structure.

Although the present invention has been described with reference to the drawings as examples, it is obvious that the present invention is not limited to the embodiments and drawings disclosed in this specification, and that various modifications can be made by those skilled in the art within the scope of the technical idea of the present invention. In addition, even if the effects according to the configuration of the present invention were not explicitly described while describing the embodiments of the present invention, it is natural that the effects predictable by the corresponding configuration should also be recognized.
