[0001] Portable device for monitoring and tracing products for inventory management in the supply chain

[0002] FIELD OF INVENTION

[0003] The present invention relates to the technical field of devices and systems for monitoring and traceability of products within the inventory management processes in supply chains of the cargo logistics sector.

[0004] BACKGROUND OF THE INVENTION

[0005] Current technological systems for inventory management are expensive, require a high investment to install, and are not suited to the needs of some companies. Furthermore, their electronic data capture devices are cumbersome for warehouse workers.

[0006] The inventory process is a crucial task for any business, as it involves keeping accurate and up-to-date records of available products. However, this process is prone to errors and consumes a significant amount of time and resources.

[0007] One of the main challenges in the inventory process is accurate product identification. Depending on the size and complexity of the inventory, manually verifying each product and its corresponding identification code can be complicated and time-consuming.

[0008] Furthermore, human errors occur during the process of recording and updating information in the inventory management system. This leads to discrepancies between the physical inventory and the digital record, resulting in financial losses and operational problems.

[0009] The development and implementation of an electronic device for identifying products in the inventory process solves these technical problems. Using a barcode (QR) reader or RFID scanner, the device allows for quick and accurate reading of product identification codes.

[0010] This significantly speeds up the identification process and reduces the possibility of human error. Furthermore, by integrating with the inventory management system, the device ensures that the information obtained is automatically updated in the central database, avoiding discrepancies between the physical inventory and the digital record.

[0011] There are several products currently available on the market that are marketed as devices for identifying products during the inventory process. However, some of these products do not meet the technical specifications required to efficiently solve the problem.

[0012] One of the most common problems is the inaccuracy in reading product identification codes. Some devices struggle to read damaged or worn barcodes, resulting in product identification errors. This leads to inventory discrepancies and operational problems.

[0013] Additionally, some devices have slow reading speeds, which slow down the product identification process and negatively impact the efficiency of the inventory process. This is especially problematic in companies with high product volumes or in situations where fast and accurate counting is required.

[0014] Another limitation some products face is a lack of integration with existing inventory management systems. This means that data obtained from the device is not automatically updated in the central database, requiring additional manual entry and increasing the risk of errors when updating inventory.

[0015] In addition, some products lack additional features that could be beneficial for inventory management, such as detailed reporting, the ability to quickly search for specific products, or the ability to send automatic alerts when inventory discrepancies are detected. In general, commercially available products lack sufficient flexibility to connect to diverse Wi-Fi networks, which limits the ability to process information across different warehouses and makes it difficult for users to improve their inventory processes on unified web platforms.

[0016] On the other hand, the identification of products, pallets, or containers using RFID radio frequency identification is a technology for quickly and efficiently identifying objects. While this technology is slightly more expensive than QR or barcode identification systems due to the need to acquire RFID tags for identifying inventory containers, pallets, or products, its tags or sensors have better technical requirements in terms of quality, environmental resistance, precision, security, and durability. However, its cost decreases in the long term because these sensors and / or tags flow throughout the supply chain in a circular manner, generating their reuse during the different stages of the logistics process.

[0017] The state of the art includes various types of commercial developments related to inventory management in the supply chain. In the field of patents, for example, we can see documents KR102007914, EP2956897, US8967457, US20220180303,

[0018] EP4232981, EP3930354, US10825120 which, in general, describe devices and systems for reading codes in inventory management.

[0019] However, there is no evidence of developments that involve, in a single solution, comprehensive inventory management based on the exchange of item reading methods, using RFID tags, QR codes, or barcodes simultaneously, as required, for inventory management within the development of activities in the freight logistics sector.

[0020] In this context, the device being disclosed solves the problem related to the identification of products and elements within the management of inventories in the supply chain, based on the integration of modules that allow the capture of information from different barcode reading systems, QR codes or RFID sensors, in an automated manner and minimizing typing errors, through the incorporation of an activated configuration that allows, in parallel, the reading of these codes in a single device integrated into a database hosted in the cloud.

[0021] BRIEF DESCRIPTION OF THE INVENTION

[0022] In a single object, the present invention reveals a portable electronic device that allows for improved functionality, efficiency, and security in data processing, among others, in the cargo logistics sector, with respect to inventory management in the supply chain.

[0023] The device of the invention is integrated into a cloud interface for traceability of inventory management in the product supply chain, in general.

[0035] The present invention arises in response to the need to provide technological solutions for improving inventory traceability in the supply chain.

[0036] The description of the embodiment of the present invention is not intended to limit its scope, but rather to serve as a particular example thereof. It is expected that one skilled in the art will understand that equivalent embodiments do not depart from the spirit and scope of the present invention in its broadest form.

[0037] The present description discloses a portable electronic device that accurately and efficiently monitors products or items stored in inventory management within the supply chain. The device seeks to improve traceability and obtains up-to-date and accurate information on the location and quantity of items in the inventory.

[0038] The device includes a recognition module for scanning barcodes and QR codes, and RFID technology for products to which tags or sensors with specific information have previously been attached.

[0039] Barcode and QR code scanning elements require a direct line of sight, while the RFID module allows product reading without the need for a line of sight.

[0040] The device uses an RFID reader in the most challenging environments that require greater accuracy in object identification and tracking. However, considering that RFID technology creates an identifier that requires associations with other attributes of inventory items, the device includes barcode and QR code readers, which use autonomously operating identifiers that provide information on their own.

[0041] Barcode readers, or readers of spaces of different widths representing numbers or characters, scan the information on different products arriving at a specific location, such as a warehouse, and convert it into readable information. Commonly known barcodes include EAN, Code 128, Code 39, UPC, and PDF417, which are used to obtain information related to the origin and product. This information is generally used by the retail industry. In turn, QR codes, unlike traditional barcodes, include editable identifiers and Wi-Fi network information, providing a greater amount of information. Both QR codes and barcodes require visual reading of lines and / or grids.

[0042] The QR code reader allows two-dimensional barcodes to be read to store a large amount of information. This code contains inventory codes and links to Wi-Fi networks. The QR code reader scans the information using an app built into the electronic device.

[0043] The device disclosed in the present description, through instructions implemented by a processor, allows the efficient identification, control and tracking of the information being processed through the integration of the simultaneous reading of barcodes, QR codes and RFID technology, for which it records said information in a database configured in an interface hosted in the cloud with which the device is integrated.

[0044] The database stores information related to each inventory item, according to its nature. This enables the flow of processes throughout the supply chain, from raw materials, suppliers, transportation, distribution, storage centers, final deliveries, and all activities related to inventory management.

[0045] The integration of these components into a single device enables data capture and processing to sort and classify products subject to inventory management in real time, achieving optimal interaction between users and information. Thus, the simultaneous exchange of reading methods for items within an inventory within the supply chain, using RFID tags, QR codes, or barcodes as required, provides flexibility and efficiency in inventory tracking and control. The device is made up of modules based on development boards that are interconnected and configured according to their respective functionality, which are described in detail below.

[0046] A processing unit based on a microcontroller (40) with at least one serial communication port (40.1) with which the connection with a processor can be verified and the respective programming can be carried out; an integrated wireless communication module that has an integrated chip with WiFi connection, compatible with the TCP / IP WIFI protocol (40.3) that connects to different WIFI network points and can make HID connection to the processor; power control modules (40.2).

[0047] The microcontroller of the device described also comprises a barcode and QR code scanning recognition module (50); an RFID reading module (20) based on a plate with antenna (20.1) and a card that has a microcontroller (20.2). This configuration allows the simultaneous identification of the data, for which these sensors work autonomously, reading, at the same time, RFID labels, barcodes and QR codes.

[0048] The information to be identified by the barcode and QR code scanning recognition module (50) and the RFID reading module (20) is stored in an internal memory of the microcontroller (40) for later sending via WiFi network. This information is displayed on a graphical user interface (60), preferably of the touch screen type, which is internally connected to the microcontroller (40) and also has an external connection to a web platform.

[0049] In the graphical interface (60) the user can view the information and perform the respective programming, as required. The connection to the web platform allows said interface (60) to be linked, through instructions implemented by the processor, with a database and in turn, to implement all the functions of said platform.

[0050] The connection of the graphical user interface (60) with the web platform also allows the information to be identified by the barcode and QR code scanning recognition module (50) and the RFID reading module (20), previously stored in the internal memory of the microcontroller (40) and then sent through the WIFI network, to be displayed on external devices, such as computers, tablets or telephones by implementing applications based on instructions implemented by the processor.

[0051] The device of the invention (1) also has a battery autonomy and power supply module (30) which includes, in turn, a microcontroller which allows the voltage and current (30.3) to be regulated; at least one battery power or charging port (30.1); at least one battery voltage output port

[0052] (30.2) that protects the device (1) in events where an overload may occur.

[0053] The power or battery charging port (30.1) of the battery autonomy and power module (30) preferably has a type C connection, which allows it to be recharged autonomously without the need to use another element.

[0054] The batteries (70) are connected to the voltage and current microcontroller

[0055] (30.3) which allows the voltage and current values ​​to be appropriate for the device. In the preferred embodiment of the invention, the batteries (70) are of the Lipo type lithium.

[0056] In the preferred embodiment of the invention the device includes a WIFI antenna (40.4).

[0057] In the preferred embodiment, the WiFi communication module is ESP8266.

[0058] The device object of this description is embedded in a housing (10), whose configuration is designed for portability and easy handling by the user, as well as to adequately protect the components that make up the device.

[0059] In the preferred embodiment, the housing (10) has a rectangular geometric configuration with a front cover (10.1); a protector (10.2); a frame (10.3) and a rear cover (10.4). The device also comprises a voltage booster (80) and a power button (90).

[0060] The particularly preferred configuration of the device includes a holding element (100) adaptable to the housing (10) that allows the user to use the device, in a versatile manner, on any extremity of the human body. Said holding element (100) in particular embodiments, may have a handle, bracelet or wristband configuration, allowing the user “hands-free” operation of the device of the invention.

[0061] A configuration and operation modality of the device of the invention is described below.

[0062] Device configuration.

[0063] The device can be configured by connecting a PE processor to the microcontroller (40), which, by means of the serial communication module (40.1), is programmed through instructions implemented by the processor. In one embodiment, the programming is carried out using C language.

[0064] Device communication

[0065] The microcontroller (40) of the device automatically acquires data through the barcode and QR code scanning recognition modules (50), as well as the RFID reading module (20); through the WiFi communication module (40.3), using instructions implemented by the processor, it sends a code to a web page host; where the page with this code collects data, as does the corresponding function to be performed.

[0066] The device starts its operation by recognizing the available WiFi network, it connects to the access network, using the respective credentials. In the event that the WIFI network cannot be used, the barcode and QR reader (50), as soon as it reads a new WiFi network, makes the connection. Then, it enters the database. The data captured by the RFID reading module (20) are sent to the web or to low connection areas to the local server. In the event that the sending is not made, the request will be made again, for the subsequent sending of the information to the database hosted in the cloud for its corresponding storage.

[0067] The data captured by the RFID reading module (20) and / or the barcode and QR code scanning recognition modules (50) are used for cases where identification is required, either item by item, containers, pallets or groups of products according to their nature, particular requirements of the operator, characteristics of the product or requirements of the environment in which it is moved.

[0068] The barcode and QR code scanning recognition modules (50) make the connection to the database and send the information to perform the different operations of entering, searching or preparing and dispatching items.

[0069] Wi-Fi network changes can be made in the middle of an operation without any additional configuration required for the device, as simply having access to another Wi-Fi network is enough for the device to connect to another router.

[0070] Once recorded, the information is sent to the database, where statistics can be generated to monitor and control inventory management activities, including recording, updating, deleting, and querying information for each product for its proper management. This information can be shared with a computer or external device connected to a Wi-Fi network, or if there is no internet connection, the data can be sent via serial communication.Any of these devices can be used to track product logistics, among other actions. This includes entering, validating, and printing information on product status, quantities, availability, or out-of-stock products. This information generates files or records with information corresponding to each product. Users can check the status, location, and / or quantity of products of interest for their respective use. The configuration of the components integrated into the disclosed device allows for portability, given the autonomy generated. It does not require wiring or connections to additional devices during operation, facilitating mobility and logistics tasks both in warehouses and on public transport.

[0071] In turn, the manufacture of the casing (10) where it is embedded is carried out from low-cost, environmentally friendly materials, being susceptible to manufacturing from 3D Printing.

[0072] Therefore, the device disclosed in this specification allows the user to operate it hands-free during the movement of merchandise or work equipment thanks to the fastening element (100) adapted to the casing that allows its location and portability on any extremity of the human body.

[0073] Although the present invention has been described with the preferred embodiments shown, it is understood that modifications and variations which retain the spirit and scope of this invention are understood to be within the scope of the appended claims.
