<Picking process>
Next, the picking process will be explained.
FIG. 7 is a flowchart showing an example of the picking process in the picking system SYS according to the present embodiment.
The picking process is started by executing a picking application on the terminal device 3.

In step S101, the server device 1 and the detection device 2 wait until the terminal device 3 executes the application. When the application is executed on the terminal device 3, the terminal device 3 executes the process of step S102.

In step S102, the terminal device 3 confirms whether it is in wireless connection with the detection device 2. If the terminal device 3 is not connected to the detection device 2, it waits until the detection device 2 is connected. When the detection device 2 is connected, the terminal device 3 executes the process of step S103.

In step S103, the terminal device 3 acquires a picking instruction from the server device 1.
In step S104, the terminal device 3 causes the display unit 34 to display a layout diagram including the positions of the article storage shelves to be picked included in the picking instruction.

In step S105, the terminal device 3 executes the process in step S106 because the detection device 2 detects the location tag. Here, if the electronic tag of the article is detected instead of the location tag, the terminal device 3 executes the process of step S109 without performing the processes of steps S105 to S108.

In step S106, the terminal device 3 waits until a plurality of location tags are detected consecutively. When location tags are detected continuously, the terminal device 3 executes the process of step S107.

In step S107, the terminal device 3 transmits to the server device 1 the continuously acquired identification information of the location tag of the article storage shelf. Further, the terminal device 3 acquires from the server device 1 a layout diagram including the current position of the detection device 2, the traveling direction of the detection device 2, and the position of the article storage shelf of the article to be picked.

In step S108, the terminal device 3 causes the display unit 34 to display a layout diagram including the current position of the detection device 2. Here, if the identification information of the electronic tag of the article is detected, the terminal device 3 executes the process of step S109. On the other hand, if the identification information of the location tag is detected, the process returns to step S106 and is executed.

In step S109, the terminal device 3 checks whether the identification information of the electronic tag of the article detected by the detection device 2 is the identification information of the electronic tag of the article to be picked. If the item is not the item to be picked, that is, if the completion notification is not received from the server device 1, the process of step S104 is executed. On the other hand, if the information is the identification information of the electronic tag of the item to be picked, that is, if the completion notification is received from the server device 1, the terminal device 3 executes the process of step S110.

In step S110, the terminal device 3 notifies the worker that the item is to be picked by audio output.

In step S111, the terminal device 3 determines whether picking of all the articles has been completed based on whether the completion button has been pressed by the operator. If the pressing of the completion button is not detected, the terminal device 3 executes the process of step S104. On the other hand, if the pressing of the "Complete" button is detected, the terminal device 3 executes the process of step S112.

In step S112, the terminal device 3 transmits a completion notification to the server device 1. Then, the picking process ends.

In this way, the terminal device 3 according to the present embodiment communicates with the detection device 2 that can detect a plurality of location tags attached to article storage shelves where articles are stored and electronic tags attached to articles. This is a terminal device 3.

In addition, the display unit 34 superimposes the position of the detection device 2 in the warehouse and the direction of movement of the detection device 2 on the warehouse layout diagram based on the fact that the detection device 2 has continuously detected a plurality of location tags. indicate.

As a result, it is possible to reduce the effort of arranging dedicated tags and sensors for detecting the positions and traveling directions of workers and trolleys in the distribution warehouse, thereby improving convenience for users. Furthermore, since the location tag is not placed on the floor, it is possible to suggest damage to the location tag. Furthermore, by using location tags affixed to article storage shelves, the current position and direction of movement can be reliably detected.

Here, based on the fact that the detection device 2 has continuously detected a plurality of location tags, the position of the detection device 2 in the warehouse and the direction of movement of the detection device 2 are displayed superimposed on the warehouse layout diagram. By displaying the location and direction of movement in the warehouse on a map based on the history of the location indicated by the location tag based on the history of detecting multiple location tags and the correspondence relationship between the corresponding location in the warehouse layout diagram. be.

Further, the picking instruction acquisition unit 361 of the terminal device 3 receives the picking instruction. The audio output unit 35 notifies that the picking of the article to be picked has been completed based on the detection device 2 detecting the electronic tag of the article to be picked.

Further, part or all of the server device 1 and the terminal device 3 in each of the embodiments and modifications described above may be realized as an LSI, which is typically an integrated circuit, or may be realized as a chipset. . Further, each functional block of the server device 1 and the terminal device 3 in each of the embodiments and modifications described above may be individually formed into a chip, or may be partially or completely integrated into a chip. Moreover, the method of circuit integration is not limited to LSI, but may be implemented using a dedicated circuit and/or a general-purpose processor. Further, if an integrated circuit technology that replaces LSI emerges due to advances in semiconductor technology, it is also possible to use an integrated circuit based on this technology.

As mentioned above, each embodiment and modification example as one aspect of the present invention has been described in detail with reference to the drawings, but the specific configuration is not limited to each embodiment and modification example, and departs from the gist of this invention. This also includes design changes to the extent that the changes will not be made. Further, one aspect of the present invention can be modified in various ways within the scope shown in the claims, and embodiments obtained by appropriately combining technical means disclosed in different embodiments may also be modified according to the technical aspects of the present invention. Included in the range. Also included are configurations in which the elements described in each of the above embodiments and modified examples are replaced with each other and have similar effects.

Although the embodiments of this invention have been described above in detail with reference to the drawings, the specific configuration is not limited to that described above, and various design changes may be made without departing from the gist of this invention. It is possible to do so.
