[0001] The present application relates to the field of logistics equipment, in particular to a smart shelf for warehouse logistics and an application system. BACKGROUND

[0002] With the continuous development of science and technology, the management of the shelf for warehouse logistics is more and more intelligent. At present, the shelf is directly built as a whole, and it is not possible to increase or reduce a part of the shelf as needed. The management of the shelf or the goods on the shelf is limited to the embodiment of data through tables and other means, and the information is complicated. SUMMARY

[0003] The present application provides a smart shelf for warehouse logistics and an application system to solve one or more of the above technical problems.

[0004] In a first aspect, the present application provides a smart shelf for warehouse logistics, which comprises a combined smart shelf,

A third sensing element is arranged on the upper surface of each of the four corners of the top of the sub-shelf, and a second sensing element is arranged on the lower surface of each of the four corners of the bottom of the sub-shelf. The position of the second sensing element corresponds to the position of the third sensing element. A first sensing element is arranged on the top of the chassis corresponding to the third sensing element.

[0006] The sub-shelf is vertically stacked on the chassis. The first sensing element and the second sensing element are in contact to generate a point position sensing signal and transmit it to the server.

[0007] Two adjacent sub-shelves in the vertical direction are stacked on each other, and the second sensing element of the upper sub-shelf is in contact with the third sensing element of the lower sub-shelf to generate a point position sensing signal and transmit it to the server.

[0008] The server is used to establish a database to store the three-dimensional model of the chassis and the three-dimensional model of the sub-shelf, construct a three-dimensional virtual environment, set the position of the chassis in the three-dimensional virtual environment and place the three-dimensional model of the chassis, and stack the three-dimensional model of the sub-shelf on the three-dimensional model of the chassis in the three-dimensional virtual environment according to the point position sensing signal.

[0009] In some embodiments, the chassis is square, and a first support is arranged on each of the four corners of the chassis. A first sensing element is arranged on the top of each first support.

[0010] The sub-shelf includes a bottom frame, a top frame, and connecting columns connecting the top frame and the bottom frame. The shape and size of the bottom frame and the top frame correspond to the shape and size of the base frame. A second support is provided at each of the four corners of the bottom frame, and a second sensor is provided at the bottom of each second support. A third support is provided at each of the four corners of the top frame, and a third sensor is provided at the top of each third support. The two ends of the connecting column are connected to the second support and the third support, respectively.

[0011] In some embodiments, the top of the first support is provided with a first groove, and a first sensing element is provided on the groove wall at the bottom of the first groove;

[0012] The top of the third support is provided with a second groove, and a third sensing element is provided on the groove wall at the bottom of the second groove. The size and shape of the first groove are the same as those of the second groove, and the position of the first groove corresponds to the position of the second groove.

[0013] The bottom of the second support is provided with a protrusion, and the bottom of the protrusion is provided with a second sensor. The size, shape and position of the protrusion correspond to the size, shape and position of the second groove, respectively. The position of the second sensor corresponds to the position of the third sensor and the position of the first sensor.

[0014] In some implementations, one or more of the four sides of the sub-shelf (front, back, left, and right) are enclosed with protective netting, which is connected to the top frame, bottom frame, and connecting posts.

[0015] In some embodiments, the bottom frame of the sub-shelf is provided with a tray in the middle, and the tray is provided with a downward recessed groove at the connection between the tray and the bottom frame. The bottom of the groove is provided with multiple through holes.

[0016] In some embodiments, an auxiliary connecting block with a high center and low sides is provided between the pallet and the four second supports on the sub-shelf, and the bottom of the auxiliary connecting block is connected to the groove wall of the groove.

[0017] The back of the tray is provided with a downwardly extending extension block and a reinforcing rib that avoids the through hole at the connection between the back of the tray and the bottom frame. The extension block is provided with a groove, and the through hole penetrates the extension block vertically. The height of the bottom surface of the extension block is less than or equal to the height of the bottom surface of the side of the bottom frame.

[0018] Secondly, this invention proposes a rack management system for warehousing and logistics using the aforementioned intelligent racks, comprising a modular intelligent rack, a server, and a rack management terminal.

[0019] Modular intelligent shelving includes one or more base frames and one or more sub-shelves stacked on the base frames, the sub-shelves being used to place goods.

[0020] The sub-shelves are stacked vertically on the base frame. When the first sensor comes into contact with the second sensor, a point-sensing signal is generated.

[0021] When two adjacent sub-shelves are stacked vertically, the second sensor of the upper sub-shelf comes into contact with the third sensor of the lower sub-shelf, generating a point sensing signal;

[0022] The server includes a main control module, a data transmission module, a 3D model processing module, and a storage module. The data transmission module, the 3D model processing module, and the storage module are all connected to the main control module.

[0023] The data transmission module is connected to the first sensor, the second sensor, the third sensor, and the shelf management terminal. It is used to receive point sensing signals generated between the base frame and the sub-shelf, and between two adjacent sub-shelves in the vertical direction, and to obtain information imported by the shelf management terminal.

[0024] The storage module is used to create a database, which stores the 3D model of the base frame and the 3D model of the sub-shelves.

[0025] The 3D model processing module is used to construct a 3D virtual environment. In the 3D virtual environment, the 3D model of the base frame is placed according to the position and placement method of the base frame. Based on the point sensing signal, the 3D models of the sub-shelves are stacked on the 3D model of the base frame in the 3D virtual environment.

[0026] The shelving management terminal is used to import 3D models of the base rack and sub-shelves into the server, set the position and placement of the base rack, and display the stacking status of the 3D models of the base rack and sub-shelves in the 3D virtual environment.

[0027] In some embodiments, the goods are affixed with a label containing goods information, including the type of goods, name of goods, production date of goods, shelf life of goods, type of shape of goods, and volume of goods.

[0028] Each sub-shelf and base frame is equipped with auxiliary identification components, and each sub-shelf and base frame contains a local storage module. Both the local storage module and the auxiliary identification components contain identification information. The data transmission module is also used to acquire the identification information of each sub-shelf and base frame included in the modular intelligent shelving unit and store it in the database.

[0029] The shelving management system also includes a handheld scanning device connected to the data transmission module. The handheld scanning device is used to scan and identify the goods information contained in the identification pieces and the identification information contained in the auxiliary identification pieces. The handheld scanning device is also equipped with a trigger, which signals the corresponding sub-shelf to be filled by clicking the trigger.

[0030] The database also stores the volume of the sub-shelves, the upper limits of the length, width, and height of the goods placed in the sub-shelves, the limits of volume difference, the limits of the remaining shelf life, the identification information of each sub-shelf and base frame contained in the modular intelligent shelf, and the information of the goods.

[0031] The server also includes a data processing module connected to the main control module. The data processing module is used to calculate the volume of goods in the sub-shelf and compare it with the volume of the sub-shelf, and then feed the comparison result back to the main control module.

[0032] In some embodiments, the outer side wall of the sub-shelf is provided with a plurality of indicator lights, including green indicator lights, yellow indicator lights and red indicator lights;

[0033] The server also includes a signal feedback module connected to the main control module. The signal feedback module is connected to the indicator light and is used to obtain the comparison result in the main control module. Based on the comparison result, a corresponding indicator light control command is generated to control the corresponding indicator light to light up.

[0034] In some implementations, the working method of the shelving management system includes the following steps:

[0035] Multiple base frames are placed on the ground as needed, and the connection between the first sensor and the local storage module on the base frame and the server is established.

[0036] By inputting the location and placement method of the base frame through the shelf management terminal, a three-dimensional virtual environment is constructed and displayed. Based on the location and placement method of the base frame, the corresponding three-dimensional model of the base frame is placed in the three-dimensional virtual environment to form the basic model.

[0037] Sub-shelves are stacked on the base frame. A point sensing signal is generated by the contact between the first and second sensors. The server confirms the identification information of the base frame and the sub-shelves based on the point sensing signal.

[0038] Based on the identification information of the base frame, place the 3D model of the sub-shelf on the corresponding 3D model of the base frame in the 3D virtual environment. The bottom of the 3D model of the sub-shelf is joined with the top of the 3D model of the base frame, forming a virtual storage space with unlimited height above the sub-shelf.

[0039] One sub-shelf is stacked on top of another sub-shelf. A point sensing signal is generated by the third sensor of the lower sub-shelf contacting the second sensor of the upper sub-shelf. The server confirms the identification information of the lower and upper sub-shelves based on the point sensing signal.

[0040] Based on the identification information of the sub-shelf below, place another 3D model of the sub-shelf on the corresponding 3D model of the sub-shelf in the 3D virtual environment. The bottom of the 3D model of the upper sub-shelf is joined with the top of the 3D model of the upper sub-shelf. A closed virtual storage space is formed above the lower sub-shelf, and an unlimited virtual storage space is formed above the upper sub-shelf. When the virtual storage space is clicked, the item information of the goods stored in the storage space is displayed.

[0041] Stack goods on the sub-shelves;

[0042] Scan the identification tags on the goods using a handheld scanning device to obtain the goods information contained in the tags;

[0043] Store the goods information in correspondence with the identification information of the sub-shelves;

[0044] Confirm whether the sub-shelf is full, specifically including the following two situations:

[0045] Click the trigger on the handheld scanner to confirm that the sub-shelf is full;

[0046] Without clicking the trigger on the handheld scanning device, calculate the sum of volumes V of all goods information corresponding to the identification information of the same sub-shelf, and obtain the difference between V and the volume of the sub-shelf. Compare the difference with the volume difference limit. If it is less than or equal to the volume difference limit, it is determined that the sub-shelf is full; otherwise, it is determined that the sub-shelf is not full.

[0047] The signal feedback module generates corresponding indicator light control commands based on whether the sub-shelf is full, controlling the corresponding indicator light to light up. When the sub-shelf is full, the red indicator light lights up, and the corresponding storage space displayed in the shelf management system is filled with red; when the sub-shelf is not full, the green indicator light lights up, and the corresponding storage space displayed in the shelf management system is filled with green.

[0048] Simultaneously, the production date and shelf life of the goods, as well as the current date, are obtained from the goods information. The remaining shelf life of the goods is calculated. If the remaining shelf life of the goods is less than the limit of the remaining shelf life, the goods are determined to be nearing their expiration date; otherwise, the goods are determined to be close to their expiration date.

[0049] The signal feedback module generates corresponding indicator light control commands based on whether the goods are about to expire, controlling the corresponding indicator light to light up. When the goods are close to their expiration date, the yellow indicator light lights up, and a yellow icon is displayed in the upper right corner of the corresponding storage space in the shelf management system. Clicking on the yellow icon displays the goods information for the goods that are about to expire; otherwise, the yellow indicator light is off, and the yellow icon is not displayed in the upper right corner of the corresponding storage space in the shelf management system.

[0050] The advantages of the intelligent shelving and application system for warehousing and logistics described in this invention are as follows:

[0051] With a simple structure, the intelligent shelving for warehousing and logistics is built by means of building blocks. One or more sub-shelves or base frames can be added or removed before, during and after use, which can effectively improve the user experience.

[0052] The individual positioning of the base frame and sub-shelves can be achieved by setting the first, second and third sensors, which facilitates the confirmation and construction of the three-dimensional models of the base frame and sub-shelves in the three-dimensional virtual environment. This allows the sub-shelves in the real environment and the three-dimensional virtual environment to be stacked accordingly, and better reflects the status of the intelligent shelves for warehousing and logistics in the real environment by applying the three-dimensional model in the three-dimensional virtual environment.

[0053] The construction of a 3D virtual environment and the building of a 3D model facilitate a more intuitive and comprehensive viewing of intelligent shelves used in warehousing and logistics.

[0054] By setting up a handheld scanning device, it is possible to better match the imported cargo information. For the volume impact caused by the accumulation of irregular items, or the placement requirement that other goods cannot be stacked on top, the trigger on the handheld scanning device can be used to determine whether the goods are full, making the judgment closer to the storage requirements.

[0055] It can monitor the information of goods and remind users to pay attention to the status of goods in the storage space by displaying different colored lights on the sub-shelves and displaying the color change of the storage space on the shelf management system, so that users can make timely adjustments.

[0056] When hoisting goods, the entire sub-shelf can be moved directly along with the goods, or the goods on the sub-shelf can be lifted or removed directly. Attached Figure Description

[0069] Two adjacent sub-shelves 2 in the vertical direction are stacked on top of each other, and the second sensor 303 of the upper sub-shelf 2 contacts the third sensor 302 of the lower sub-shelf 2 to generate a point sensing signal and transmit it to the server.

[0070] The server is used to create 3D models of the database storage rack and sub-racks, construct a 3D virtual environment, set the position of rack 1 in the 3D virtual environment and place the 3D model of the rack, and stack the 3D models of the sub-racks on the 3D model of the rack in the 3D virtual environment according to the point sensing signal.

[0071] The base frame 1 is square, and a first support 101 is provided at each of the four corners of the base frame 1. A first groove 111 is provided at the top of each first support 101, and a first sensing element 301 is provided on the groove wall at the bottom of the first groove 111.

[0072] Sub-shelf 2 includes a bottom frame, a top frame, and connecting columns 204 that connect the top frame and the bottom frame. The shape and size of the bottom frame and the top frame correspond to the shape and size of the base frame 1.

[0073] A second support 202 is provided at each of the four corners of the bottom frame. A second sensor 303 is provided at the bottom of each second support 202. A protrusion 201 is provided at the bottom of the second support 202. The second sensor 303 is provided at the bottom of the protrusion 201. The size, shape and position of the protrusion 201 correspond to the size, shape and position of the second groove 261. The size, shape and position of the protrusion 201 also correspond to the size, shape and position of the first groove 111. The position of the second sensor 303 corresponds to the position of the third sensor 302 and the position of the first sensor 301.

[0074] A third support 206 is provided at each of the four corners of the top frame. A second groove 261 is provided at the top of each third support 206. A third sensing element 302 is provided on the groove wall at the bottom of the second groove 261. The two ends of the connecting column 204 are connected to the second support 202 and the third support 206 respectively.

[0075] In some specific implementations, protective netting 205 can be applied to one or more of the four sides of the sub-shelf 2 (front, back, left, and right) to prevent goods from falling off. The protective netting 205 is connected to the top frame, bottom frame, and connecting column 204.

[0076] The bottom frame of the sub-shelf 2 has a tray 209 in the middle. The tray 209 has a recessed groove 291 at the connection between the tray and the bottom frame. The bottom of the groove 291 has multiple through holes 292.

[0077] An auxiliary connecting block 293 with a high center and low sides is provided between the pallet 209 and the four second supports 202 on the sub-shelf 2. The bottom of the auxiliary connecting block 293 is connected to the groove wall of the groove 291.

[0078] The back of the pallet 209, where it connects to the bottom frame, features a downwardly extending extension block 295 and a reinforcing rib 294 that avoids the through hole 292. The extension block 295 corresponds to the groove 291, and the through hole 292 vertically penetrates the extension block 295. The height of the bottom surface of the extension block 295 is less than or equal to the height of the bottom surface of the side of the bottom frame.

[0081] In addition to the above-mentioned structure, the bottom frame also includes two third side plates 203 and two fourth side plates 210 for connecting the four second supports 202. The bottom surface of the extension block 295 is at a height lower than the bottom surface of the third side plate 203 and the bottom surface of the fourth side plate 210. The extension block 295 is designed to prevent water discharged through the through hole 292 from transferring along the bottom frame.

[0082] In addition to the structure described above, the top frame also includes two fifth side plates 207 and two sixth side plates 208 for connecting the four third supports 206.

[0084] Example 2

[0085] A warehouse logistics intelligent shelf management system described in Application Embodiment 1 includes a modular intelligent shelf, a server, a shelf management terminal, and a handheld scanning device. The modular intelligent shelf, the shelf management terminal, and the handheld scanning device are all connected to the server.

[0086] The modular intelligent shelving includes one or more base frames 1, and one or more sub-shelves 2 stacked on the base frames 1, the sub-shelves 2 being used to place goods, wherein:

[0087] The goods have labels affixed to their surface, which contain information about the goods, including the type of goods, name of the goods, production date of the goods, shelf life of the goods, type of shape of the goods, and volume of the goods.

[0088] Both the sub-shelf and the base frame are equipped with auxiliary identification components. Both the sub-shelf and the base frame are equipped with local storage modules, which are connected to their corresponding sensors (the local storage module on the sub-shelf is connected to the second sensor 303 and the third sensor 302 on the sub-shelf, and the local storage module on the base frame is connected to the first sensor 301 on the base frame). Both the local storage module and the auxiliary identification components contain identification information.

[0089] The sub-shelves 2 are stacked vertically on the base frame 1. The first sensor 301 and the second sensor 303 come into contact, generating a point sensing signal.

[0090] When two adjacent sub-shelves 2 are stacked vertically, the second sensor 303 of the upper sub-shelf 2 comes into contact with the third sensor 302 of the lower sub-shelf 2, generating a point sensing signal;

[0091] The server includes a main control module, a data transmission module, a 3D model processing module, a storage module, and a data processing module. All of these modules are connected to the main control module.

[0092] The data transmission module is connected to the first sensor 301, the second sensor 303, the third sensor 302, the shelf management terminal, and the handheld scanning device. It is used to receive point-sensing signals generated between the base frame 1 and the sub-shelf 2, and between two adjacent sub-shelves 2 in the vertical direction, and to acquire information imported by the shelf management terminal.

[0093] It is also used to obtain the identification information of each sub-shelf and base frame contained in the modular intelligent shelving;

[0094] The storage module is used to establish a database, which stores the 3D model of the base frame, the 3D model of the sub-shelves, the volume of the sub-shelves, the upper limit of the length, width and height of the goods placed in the sub-shelves, the limit of the volume difference, the limit of the remaining shelf life, the identification information of each sub-shelf and base frame contained in the modular intelligent shelving, and the goods information.

[0095] The 3D model processing module is used to construct a 3D virtual environment. In the 3D virtual environment, the 3D model of the base frame is placed according to the position and placement method of the base frame. Based on the point sensing signal, the 3D models of the sub-shelves are stacked on the 3D model of the base frame in the 3D virtual environment.

[0096] The data processing module is used to calculate the volume of goods in the sub-shelf and compare it with the volume of the sub-shelf, and then feed the comparison result back to the main control module.

[0097] The shelving management terminal is used to import the 3D model of the base frame and the 3D model of the sub-shelves into the server, set the position and placement method of the base frame 1, and display the stacking status of the 3D model of the base frame and the 3D model of the sub-shelves in the 3D virtual environment.

[0098] The handheld scanning device is used to scan and identify the cargo information contained in the identification items and the identification information contained in the auxiliary identification items. The handheld scanning device is also equipped with a trigger, which signals the corresponding sub-shelf to be filled by clicking the trigger.

[0099] The outer wall of the sub-shelf 2 is equipped with multiple indicator lights, including green indicator lights, yellow indicator lights and red indicator lights;

[0100] The server also includes a signal feedback module connected to the main control module. The signal feedback module is connected to the indicator lights and is used to obtain the comparison results in the main control module. Based on the comparison results, it generates corresponding indicator light control commands to control the corresponding indicator lights to light up.

[0101] Before the rack management system starts operating, it constructs a three-dimensional model of the base frame 1 and the sub-rack 2 based on their structures, and then stores the model in the server through the rack management terminal.

[0102] Combination Figure 6 The working method of the shelving management system, as shown, includes the following steps:

[0103] S1. Construct the modular intelligent shelf and its corresponding 3D model. The specific process is as follows:

[0104] Users can directly place multiple base frames 1 on the ground as needed, connect the first sensing elements 301 on all the base frames 1 in series, and then connect them to the server.

[0105] Users input the location and placement method of base frame 1 through the shelf management terminal to construct and display a three-dimensional virtual environment. Based on the location and placement method of base frame 1, the corresponding three-dimensional model of base frame 1 is placed in the three-dimensional virtual environment to form a basic model. The three-dimensional model of base frame 1 in the three-dimensional virtual environment corresponds to the identification information of base frame 1 in the storage module.

[0106] Users stack sub-shelves 2 on the base frame 1. The bottom of the sub-shelves 2 engages with the top of the base frame 1 (i.e., the protrusion 201 at the bottom of the sub-shelves 1 is embedded in the first groove 111 at the top of the base frame 1 below). The first sensor 301 contacts the second sensor 303 to generate a point sensing signal. The server confirms the identification information of the base frame 1 and the sub-shelves 2 based on the point sensing signal.

[0107] The server places the 3D model of the sub-shelf 2 on the 3D model of the corresponding base frame 1 in the 3D virtual environment according to the identification information of the base frame 1. The bottom of the 3D model of the sub-shelf 2 is joined with the top of the 3D model of the base frame 1, forming a virtual storage space with unlimited height above the sub-shelf 2, and assigning the identification information of the sub-shelf 2 to the virtual storage space.

[0108] Another sub-shelf 2 is stacked on top of sub-shelf 2, with the bottom of the upper sub-shelf 2 engaging with the top of the lower sub-shelf 2 (i.e., the protrusion 201 at the bottom of the upper sub-shelf 2 is embedded in the second groove 261 at the top of the lower sub-shelf 2). A point sensing signal is generated by the contact between the third sensor 302 of the lower sub-shelf 2 and the second sensor 303 of the upper sub-shelf 2. The server confirms the identification information of the lower sub-shelf 2 and the upper sub-shelf 2 based on the point sensing signal.

[0109] Based on the identification information of the lower sub-shelf 2, place another 3D model of sub-shelf 2 on the corresponding 3D model of sub-shelf 2 in the 3D virtual environment. The bottom of the 3D model of the upper sub-shelf 2 is joined with the top of the 3D model of the upper sub-shelf 2. A closed virtual storage space is formed above the lower sub-shelf 2, and a virtual storage space with unlimited height is formed above the upper sub-shelf 2. The identification information of the lower sub-shelf 2 is assigned to the closed virtual storage space, and the identification information of the upper sub-shelf 2 is assigned to the virtual storage space with unlimited height.

[0110] Similarly, a 3D model of the modular smart shelf is constructed in the 3D virtual environment. After goods are stacked on the modular smart shelf, clicking on the location of the virtual storage space in the 3D virtual environment will display the item information of the goods stored in that storage space. At the same time, the difference between the sum of the volumes of the items stored in the sub-shelf and the volume can be displayed as needed.

[0111] S2. Stack goods on sub-shelf 2;

[0112] S3. Users scan the identification tags on goods using a handheld scanning device to obtain the goods information contained in the tags and transmit it to the server.

[0113] S4. Store the goods information and the identification information of the storage space in the server.

[0114] S5. Confirm whether sub-shelf 2 is full, specifically including the following two situations:

[0115] S5.1 Click the trigger on the handheld scanning device to confirm that sub-shelf 2 is full. This prevents irregularly shaped items from crowding out other spaces and causing them to become unusable.

[0116] S5.2 Situation of estimation errors caused by calculation;

[0117] S5.2. Without clicking the trigger on the handheld scanning device, calculate the sum of volumes V of all goods information corresponding to the identification information of the same sub-shelf 2, and obtain the difference between V and the volume of the sub-shelf. Compare the difference with the volume difference limit. If it is less than or equal to the volume difference limit, it is determined that the sub-shelf 2 is full; otherwise, it is determined that the sub-shelf 2 is not full.

[0118] S6. The signal feedback module generates a corresponding indicator light control command based on whether sub-shelf 2 is full, and controls the corresponding indicator light to light up. If sub-shelf 2 is full, the red indicator light lights up, and the corresponding storage space displayed in the shelf management system is filled with red; if sub-shelf 2 is not full, the green indicator light lights up, and the corresponding storage space displayed in the shelf management system is filled with green.

[0119] S7. While executing S5, determine whether the product is nearing its expiration date, obtain the production date and expiration date of the product from the product information, as well as the current date, and calculate the remaining shelf life of the product. If the remaining shelf life of the product is less than the limit of the remaining shelf life, the product is determined to be nearing its expiration date; otherwise, the product is determined to be nearing its expiration date.

[0120] S8. The signal feedback module generates corresponding indicator light control commands based on whether the goods are about to expire, controlling the corresponding indicator light to light up. When the goods are nearing their expiration date, the yellow indicator light lights up, and a yellow icon is displayed in the upper right corner of the corresponding storage space in the shelf management system. Clicking the yellow icon displays the goods information of the goods that are about to expire. Conversely, when the goods are not nearing their expiration date, the yellow indicator light is off, and the yellow icon is not displayed in the upper right corner of the corresponding storage space in the shelf management system.

[0121] The handheld scanning device and shelf management terminal mentioned above can be implemented directly using existing technologies or devices, so they will not be elaborated on here.

[0122] The aforementioned indicator light can be installed at any position on the outer side of the bottom frame, top frame, or connecting column 204 that is clearly visible, depending on where the user places the sub-shelf. The indicator light is also connected to the second and third sensors on the sub-shelf.

[0123] During the operation of the shelving management system, the number of base shelves and / or sub-shelves can be increased or decreased as needed. When the base shelves and / or sub-shelves change, the 3D model in the 3D virtual environment also changes accordingly. For example, when a sub-shelf is reduced, the connection between the reduced sub-shelf and other sub-shelves or base shelves disappears, the generated point sensing signals vanish, the corresponding sub-shelf identification information stored in the storage module is deleted, and the corresponding sub-shelf model in the 3D virtual environment is deleted. Other addition and deletion operations can follow the steps described above, and therefore will not be elaborated upon here.

[0124] The above description is merely a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several similar modifications and improvements can be made without departing from the inventive concept of the present invention, and these should also be considered within the scope of protection of the present invention.
