FIG. 1 illustrates a system for managing the location of materials in an indoor warehouse and / or outdoor yard with a material rack 10 according to an embodiment of the present invention.

1, a system for managing the position of a material includes first wireless sensors 100a, 100b, 100k, and 100x that generate and emit wireless signals including absolute position information and corresponding identification numbers, materials 20a, (100a, 100b, 100k, 100x) and / or the second wireless sensor (110a, 110k, 100x) that is attached to the first wireless sensor A mobile terminal 400 capable of receiving radio signals radiated from the second wireless sensors 110a, 110k, and 100x and obtaining identification numbers corresponding to absolute positions and materials, And a server system 300 that performs material management based on information from the terminal 400. In addition, the mobile terminal 400 may further include a gateway 200 for mediating data communication between the mobile terminal 400 and the server system 300.

The first wireless sensors 100a, 100b, 100k, and 100x and the second wireless sensor 110 are wireless sensors having identification numbers such as beacon IDs, which can distinguish themselves from other sensors. Such a wireless sensor may be a beacon of BLE (Bluetooth Low Energy).

The first wireless sensors 100a, 100b, 100k, and 100x are set such that the respective identification numbers and the absolute position information correspond to each other at initial installation. Such setting information may be stored in the server system 300. [

One embodiment of the setting will now be described with reference to FIG. 1, where the zones on which the material can be placed by the material shelf 10 in the material warehouse can be distinguished three-dimensionally and each zone of the material shelf 10 can be divided into 10a To 10l. ≪ / RTI > And a first wireless sensor for each compartment can be installed. As an example, the first wireless sensor 100k may be set to correspond to a 10k zone in the material rack. Therefore, when the identification number of the first wireless sensor 100k corresponding to the zone 10k in which the material 20k is stored is transmitted to the server system 300, the server system 300 determines whether the material 20k is stored in the material rack 10, As shown in FIG. The setting of the first wireless sensor may be similar in the outdoor yard. That is, the first wireless sensor 100x is installed in the upper right corner of the outdoor yard 40 and the identification number of the first wireless sensor 100x is stored in the server system 300 in the zone 10k where the material 20x is stored. The server system 300 can see that the material 20x is loaded in the upper right corner of the outdoor yard 40 corresponding to the first wireless sensor 100x.

In addition, the first wireless sensor is installed at a door of a material warehouse so that the mobile terminal 400 can recognize that the material has arrived in the warehouse. In more detail, the mobile terminal 400 acquires the identification number of the first wireless sensor 100b and transmits it to the server system 300 through the gateway 200 while passing through the door. Then, the server system 300 confirms that the mobile terminal 400 enters the specific material warehouse based on the received identification number of the first wireless sensor 100b, and stores the material loading structure of the material warehouse in the mobile terminal 400 Information such as material status can be transmitted. Then, the mobile terminal 400 can display the structure of the material warehouse in a map form based on the information transmitted from the server system 300, and display the material state on the map.

Thus, the first wireless sensors 100a, 100b, 100k, and 100x can be used to identify the absolute fixed position where the material is stored or the position of the mobile terminal 400. [

The second wireless sensor 110 may be attached to the material 20 and moved with the material. The information related to the material 20 and the identification number of the second wireless sensor 110 attached to the material 20 can be associated and stored together in the server system 300 when the material 20 is first brought into a factory or the like . Then, the server system 300 recognizes the identification number of the second wireless sensor 110 and can acquire information about the material to which the second wireless sensor 110 is attached.

The mobile terminal 400 may receive a wireless signal from the first wireless sensor 100a, 100b, 100k, 100x and / or the second wireless sensor 110 to obtain an identification number. The mobile terminal 400 can be connected to the gateway 200 through wireless communication to transmit and receive data and can transmit the identification number received by the server system 300 through the gateway 200. In addition, the mobile terminal 400 may receive the absolute position information or the material information corresponding to the identification number transmitted from the server system 300. Based on the information, the mobile terminal 400 may display the first wireless sensors 100a, 100b, 100k, and 100x on a map corresponding to the loading structure of the material warehouse, and may display the location of the material.

The mobile terminal 400 also selects the identification numbers of the first wireless sensors 100a, 100b, 100k, and 100x corresponding to the areas where the materials are placed at the time of arrival of the materials 20 and transmits them to the server system 300, 20 can be recognized by the server system 300 and stored therein. If the position of the material 20 is changed, the identification number of the first wireless sensor 100a, 100b, 100k, 100x corresponding to the current position of the changed material is transmitted to the server system 300, May store the current position of the stored material by changing it to the area corresponding to the received identification number.

A LoRa communication protocol may be used for data communication between the mobile terminal 400 and the gateway 200. [ Laura Communications is an IoT-only wireless communication scheme for low-power long distance communications as proposed by the LoRa Alliance. In the case of using Laura communication, it is possible to cover a large area with one gateway 200, thereby minimizing the network infrastructure. In addition, WiFi or ZigBee communication protocols can be used. Wi-Fi is a wireless LAN communication method for transmitting data based on the IEEE 802.11 standard, and ZigBee is one of IEEE 802.15.4 standards for supporting short-range communication and is a communication method capable of supporting wireless networking in a home office or the like.

The gateway 200 includes a wireless communication module and a wired communication module and performs data communication with the mobile terminal 400 using the wireless communication module and performs data communication with the server system 300 using the wired communication module . Therefore, the gateway 200 can perform the function of mediating the exchange of data between the mobile terminal 400 and the server system 300.

In this case, the gateway 200 may be connected to the plurality of mobile terminals 400 through a wireless communication method. When the gateway 200 transmits information received from the plurality of mobile terminals 400 to the server 300, However, it is also possible to combine the information from the mobile terminal into a single data packet and transmit the data packet.

The server system 300 that manages the entire material location management system and performs the material management based on the information from the mobile terminal 400 uses the identification number received from the mobile terminal 400 via the gateway 200 Thereby estimating the position of the mobile terminal 400 at present.

The server system 300 transmits information on the loading structure of the material warehouse to the mobile terminal 400 when the mobile terminal 400 is passing through the door of the material warehouse, Or display the material shelf in a map form and display the first wireless sensor 100a, 100b, 100k, 100x and material information. When the server system 300 receives the identification numbers of the first wireless sensors 100a, 100b, 100k, and 100x installed in the outdoor yard 40 from the mobile terminal 400, Information of the outdoor yard 40 can be displayed on the screen of the mobile terminal 400 in a graphic form by transmitting the information to the mobile terminal 400. [

In this case, the server system 300 provides the mobile terminal 400 with information on all the materials loaded in the material warehouse or the outdoor yard. When the mobile terminal 400 requests the location confirmation of a specific material, The location of the specific material may be informed to the mobile terminal 400 based on the information.

When the server system 300 receives an identification number corresponding to a specific location from the mobile terminal 400, the server system 300 can transmit the material information stored in the area corresponding to the identification number to the mobile terminal 400. Then, the manager using the mobile terminal 400 can confirm which material is loaded at a specific position.

The server system 300 also identifies the first wireless sensor 100a, 100b, 100k, 100x corresponding to the identification number of the second wireless sensor 110 attached to the material coming from the mobile terminal 400 and the material loading position, The location of the material can be stored using the number. When receiving the pair of the identification numbers of the new second wireless sensor 110 and the first wireless sensors 100a, 100b, 100k, and 100x by the change of the material loading position, Can be changed.

FIG. 2 is a flowchart illustrating a flow of setting a position of an incoming material according to an embodiment of the present invention.

In order to properly manage the material, it is necessary to recognize the loading position of the material in real time from the arrival to the shipment of the material. FIG. 2 shows a flow chart for storing this location information in the server system 300 when the first material is received or when the location of the material is changed after the arrival.

2, the server system 300 corresponds to the absolute position information having information on the position where the material can be loaded and the identification numbers of the first wireless sensors 100a, 100b, 100k, and 100x (S210) . As a result, the location where the material is loaded can be specified using the identification numbers of the first wireless sensors 100a, 100b, 100k, and 100x. The second wireless sensor 110 is attached to the first incoming material. The server system 300 may store the material information and the identification number of the second wireless sensor 110 attached to the material 20 (S220) together. The server system 300 may then use the identification number of the second wireless sensor 110 to obtain information about the material to which the second wireless sensor 110 is attached.

Next, when material enters the material warehouse, the manager can load the material into a specific location in the material warehouse. The mobile terminal 400 can then obtain the identification number from the radio signals coming from the first wireless sensor 100a, 100b, 100k, 100x corresponding to the loaded location, and the second wireless The identification number may be obtained from the wireless signal from the sensor 110 (S230). The manager correlates the identification number obtained from the first wireless sensors 100a, 100b, 100k, and 100x with the identification number obtained from the second wireless sensor 110 and transmits it to the server system 300 (S240). Then, the server system 300 can store the position of the material on the basis of the two identification numbers transmitted (S250).

Even when the material warehouse manager changes the loading position of a specific material, the identification numbers obtained from the first wireless sensors 100a, 100b, 100k, and 100x and the identification numbers obtained from the second wireless sensor 110 are associated with each other after the same movement The server system 300 can transfer the position of the material to the new position and store the changed position.

3 is a view showing another embodiment of a flow for setting the position of a material according to the present invention.

In the case of FIG. 2, a manual operation for associating an identification number obtained from the first wireless sensors 100a, 100b, 100k, and 100x acquired by the administrator with the mobile terminal 400 and an identification number obtained from the second wireless sensor 110 Should be performed. FIG. 3 shows a method for automatically setting the position by eliminating the manual operation.

3, the server system 300 corresponds to the absolute position information having information on the position where the material can be loaded and the identification numbers of the first wireless sensors 100a, 100b, 100k, and 100x (S310) . As a result, the location where the material is loaded can be specified using the identification numbers of the first wireless sensors 100a, 100b, 100k, and 100x. The second wireless sensor 110 is attached to the first incoming material. The server system 300 may store the material information and the identification number of the second wireless sensor 110 attached to the material 20 in correspondence (S320). The server system 300 may then use the identification number of the second wireless sensor 110 to obtain information about the material to which the second wireless sensor 110 is attached.

Next, when material enters the material warehouse, the manager can load the material into a specific location in the material warehouse. The second wireless sensor 110 may acquire the identification number of the first wireless sensor 100a, 100b, 100k, 100x corresponding to the position where the second wireless sensor 110 is loaded (S330) Transmits a radio signal including its own identification number and the identification number of the acquired first radio sensors 100a, 100b, 100k, and 100x (S340). The mobile terminal 400 obtains the identification number of the second wireless sensor 110 and the identification number of the first wireless sensor 100a, 100b, 100k, 100x from the wireless signal transmitted by the second wireless sensor 110, It is directly transferred to the server system (S340). At this time, unlike the case of FIG. 2, the position information of the material can be directly transmitted to the server system 300 without the intervention of the administrator. The server system 300 may store the location of the material based on the two identification numbers transmitted (S250).

The above two methods are different from each other only in the manner in which the mobile terminal 400 acquires the identification numbers of the second wireless sensor 110 and the first wireless sensors 100a, 100b, 100k, and 100x related to the location where the material and the material are loaded . In the method of FIG. 3, the functions of the second wireless sensor 110 and the first wireless sensors 100a, 100b, 100k, and 100x may differ. In contrast, in the method of FIG. 2, 1 wireless sensors 100a, 100b, 100k, and 100x perform the same function.
