Description

{INVENTORY ON-SITE MANAGEMENT SYSTEM BASED ON NFC AND MOBILE APP}

The present invention relates to an on-site asset management system based on NFC and a mobile app, and more specifically, to an on-site asset management system that eliminates complex management methods and procedures of the past and processes information in real time on-site when managing inspection and maintenance of assets being operated or held as spare materials in various fields, thereby enabling efficient history management and maintenance.

In general, facilities, machinery, and other assets operated by various central government agencies or various departments under an organization undergo management tasks such as inspection and maintenance on a regular or ad hoc basis.

For example, various facilities and devices such as distribution panels, flow meters, and transfer pumps are installed at the sites of water intake facilities, water purification plants, drainage plants, pumping stations, and sewage treatment plants of water and sewage treatment facilities. In the past, management was carried out through procedures such as the manager or user of the department managing the relevant facilities or devices periodically visiting the site to check the condition of the property, repairing the facility or device when it broke down, and recording the condition of the property, the results of the inspection, and the details of the repairs in a designated property management table placed on one side, or recording the condition of the property or repair information identified at the site in a designated management ledger kept within the management department and then creating a document and storing it, and regularly reporting the relevant statistics to the central government.

In addition, in order to define the limits of responsibility for property such as facilities and equipment on site, management signs with the names of management personnel, such as Jeong and Bu, are attached to each facility or equipment to manage the property.

However, since most of the conventional asset management methods involve manual recording of work or moving what happens on site to the management department and then recording it, there is always the possibility of information distortion or change. In addition, if the types and quantities of assets being managed are large, there is a problem that considerable time and effort is required to identify, record, and store information one by one.

In order to solve the above problems, a computerized management system for asset management has been established within the management department recently, and a method of inputting, storing, and managing the contents of management, inspection, and maintenance that occur on-site, which were recorded manually on-site, is being introduced. Let's take a look at the outline of the contents with reference to the known technology.

As an example, Korean Patent No. 10-0395265 relates to a method for integrated operation management of environmental infrastructure facilities and a process system therefor, which comprises a treatment facility management step including a step in which inspection of measuring instruments is performed by referring to databased equipment records, inspection ledgers, process plans, and inspection data management ledgers as scheduled inspections and periodic inspections, and configures a database of facility inspection result records using a remote management system.

As another example, Korean Patent No. 10-1780393 discloses an equipment management information providing terminal including an information request receiving unit that receives a management information request signal for an information transmission module that selects equipment based on tag information when entering inspection details for equipment by wirelessly transmitting management information about equipment to be managed and tag information attached to the equipment from an input means, an information selection unit that selects equipment management information based on search conditions among management information about equipment and information transmission modules pre-stored in a database, and an information transmission unit that processes the selected equipment management information when receiving an input request for creating an inspection management ledger, creates an inspection management ledger, and transmits the processed information to an output means.

Korean Patent No. 10-0395265 (August 21, 2003) Korean Patent No. 10-1780393 (2017.09.20)

The conventional method of managing assets to which technology is applied is one in which the manager or user checks the status of assets on-site, creates an asset management table, records the information obtained on-site in a management ledger stored within the management department, creates a document, and then refers to these documents when conducting future inspections or maintenance, or reports or stores these statistics to the central government.

The central government department that received the report uses the information to determine the durability and usage status of equipment and machinery operated by various departments under the organization, and to calculate the replacement cost of equipment that has reached the end of its lifespan or to establish a plan for estimated costs for maintenance.

However, this type of asset management method has problems such as the possibility of some information being omitted or causing confusion due to time lags between field, management, and central government work, and the increased work fatigue caused by inefficient, duplicated work.

In particular, when the types and quantities of assets to be managed are large, it takes considerable time and effort to grasp the information on-site, record the information again in the management department, and then transmit it to the central government agency. Therefore, distortion or change of information may occur during this process. In addition, if information is omitted due to personnel changes or negligence of work by the person in charge, it will be very difficult to trace the management history of the asset information later.

In addition, although some computerized asset management systems have been introduced recently to improve the above-mentioned problems, they are limited to moving information identified in the field to the management department, storing it in the management system, and making it available for use when necessary. Therefore, there is still the problem of difficulty in managing the history of asset information between the field, management department, and central government agencies.

Accordingly, the present invention was invented to solve the problems of the prior art as described above.

In the on-site asset management system based on NFC and mobile apps, which is configured to process management history in real time on-site when inspecting and maintaining assets including equipment and machinery installed at facilities constructed under the central government or organization,

An NFC tag (100) that is manufactured in a hanger or attachment type depending on the type and form of each asset and is mounted on a part of the asset to store basic asset information and provide a management identifier,

A central web server (200) that stores and provides property information and management history data for all properties subject to management by providing a management database (210) built in the central government department,

An administrator terminal (300) that is held by the administrator who manages the assets of each facility and connects to the central web server (200) to manage and provide NFC tags (100) and asset information and on-site passwords,

By including a field user terminal (400) that a field user who manages a site where assets are installed carries and installs an asset management app (410) to call or store asset information and management history data in real time from the management database (210) of a central web server (200) on site, it is possible to achieve the purpose of enabling efficient management by processing information in real time on site when searching, storing, modifying, inspecting and maintaining asset information.

The present invention provides a property field management system that allows real-time processing of inspection and maintenance of property operated in various fields using NFC and a mobile app.

Therefore, the present invention has the advantage of solving problems such as increased work time and fatigue due to duplicate work by excluding complex work procedures between conventional fields, management departments, and central government agencies, and improving efficiency.

In particular, the present invention can quickly reflect the property information that is the subject of management by directly connecting it to the database of the central government agency from the field, thereby minimizing confusion in work or distortion or alteration of information due to time lag between information transfers, and also prevents problems that occur in maintenance when property information is omitted due to personnel transfers of the person in charge, making history management impossible, thereby enabling more systematic and accurate history management.

Figure 1 is a schematic diagram of the configuration of an NFC and mobile app-based on-site asset management system according to the present invention.
Figure 2 is a flow chart of asset information inquiry, storage, modification, inspection, and maintenance management by an asset field management system based on NFC and mobile app according to the present invention.
FIG. 3 is an example diagram of a hanger-type NFC tag (a) and an attachable NFC tag (b) of an NFC and mobile app-based on-site asset management system according to the present invention.

Hereinafter, the configuration and operation of a preferred embodiment of an NFC and mobile app-based asset on-site management system of the present invention will be described in detail with reference to the attached drawings. In the following description, a detailed description of a part that can be easily implemented by a person skilled in the art may be omitted.

It is to be noted that the NFC and mobile app-based property on-site management system to which the technology of the present invention is applied relates to an NFC and mobile app-based property on-site management system that eliminates complex work procedures between conventional on-site users, managers, and central government agencies when inspecting and maintaining property including facilities and machinery operated by a central government agency or various departments under an organization, and processes information management, history management, and maintenance of property in real time on-site to achieve efficient management.

To this end, the NFC and mobile app-based asset on-site management system of the present invention comprises an NFC tag (100) mounted on each asset, a central web server (200) for integrated asset information management by a central government agency, an administrator terminal (300) used by an administrator who generates an asset management number, basic asset information, and an on-site password or manages the assets to which the administrator belongs, and an on-site user terminal (400) possessed by an on-site user who is in charge of management work at the site where the assets are installed and operated, and is specifically as follows.

NFC tags (100) are manufactured in a hanger type or attachment type as illustrated in FIG. 3 depending on the type and form of individual items, and are mounted on a part of the item to store the item management number and basic item information and provide an identifier for the item.

NFC is a non-contact short-range wireless communication technology that allows data to be sent and received with a field user terminal (400) that has an NFC function built into it, such as a smartphone, without a separate connection procedure.

NFC tags (100) have an antenna and a memory chip built into them and can be manufactured in various shapes and sizes. In the present invention, depending on the type and shape of the property to be managed, for example, in the case of devices operating in a high-temperature environment, they are provided in a hanger-type form that can be mounted using a wire material, and in the case of devices operating in a general environment, they are provided in a form that can be mounted using a ring or strap made of ABS or PP material. In the case of properties forming a normal flat appearance, they are provided in an easy-to-mount attachment form and configured to be mounted.

The NFC tag (100) stores an asset management number that is uniquely assigned to the asset by the management terminal (300) responsible for managing the asset when it is first attached to the asset, and immutable information such as the asset's name, specifications, location of use, purchase date, expiration date, and place of purchase, and allows not only authenticated on-site users but also general users to view the information by installing the asset management app (410).

In addition, the NFC tag (100) is configured to store and provide a URL so that the property management app (410) can be easily installed by redirecting the field user terminal (400) that does not have the property management app (410) installed to an app store or the like when tagging, and the property management app (410) is programmed to automatically run when tagging the field user terminal (400) that already has the property management app (410) installed.

The central web server (200) is equipped with a management database (210) built in a central government department that oversees all facilities operated by various departments under the organization where the assets are installed, and is configured to store and provide asset information and management history data for all assets subject to management.

The central web server (200) is equipped with a management database (210) that transmits and receives data by connecting to an administrator terminal (300) and a field user terminal (400) via wired or wireless communication, and a field user authentication module (220).

The management database (210) provides the asset management number initially created by the management terminal (300) and the corresponding asset basic information, as well as the management history data created by the field user terminal (400) in chronological order.

The on-site user authentication module (220) is generated by the administrator terminal (300), stored in the central web server (200), and receives the on-site password verbally delivered to the on-site users from the on-site user terminal (400) to authenticate whether or not to grant authority to the management database (210). That is, when a on-site user logs in, the on-site user terminal (400) authenticates whether the user is an authenticated internal user or a general user, and determines whether to add, modify, or delete information transmitted from the site to the management database (210), or simply provide information stored in the management database (210).

The administrator terminal (300) is used by the administrator who manages the assets of each facility and is connected to the central web server (200) via a wire to enable comprehensive management of assets belonging to the administrator of each facility.

The management terminal (300) is composed of a PC and generates and inputs a property management number and property basic information stored in an NFC tag (100). In addition, it includes a property management number setting unit (310), a field password setting unit (320), and a property information management unit (330) to enable comprehensive management of the property managed by each facility manager and to authenticate authority to the management database (210) for site managers.

The property management number setting unit (310) is a property management number that is uniquely assigned to the property to be managed when it is first installed. The manager creates these numbers and transmits them to the management database (210) of the central web server (200) for storage. The property management number setting unit (310) creates a property management number so that individual properties can be identified according to specific rules, and adds permanent and unchangeable property basic information about the property to store it in the management database (210).

The on-site password setting unit (320) is a means for authenticating the authority for on-site users to access the management database (210) of the central web server (200) using the asset management app (410) installed on the on-site user terminal (400) to modify, record, and search information. Each facility manager creates an on-site password and stores it in the on-site user authentication module (220) of the central web server (200). The on-site password setting unit (320) periodically creates and changes an on-site password according to security rules and updates and stores the password stored in the on-site user authentication module (220).

The asset information management department (330) is a function for each facility manager to comprehensively manage assets that he or she must manage, and performs tasks such as printing asset management cards according to a unique output format for each asset, printing asset ledgers, multiple searches for assets, and printing statistics on all assets managed by the affiliated department.

The field user terminal (400) is a terminal carried by a field user who manages a site where assets are installed, and is equipped with an asset management app (410) installed to access the management database (210) of the central web server (200) in real time from the site to retrieve or save asset information and management history data.

The on-site user terminal (400) is configured as a mobile device that is connected to the central web server (200) via wireless communication, such as a smart phone or tablet PC, and is equipped with an NFC function, enabling data transmission and reception by tagging an NFC tag (100) mounted on an object.

The on-site user terminal (400) is configured to install a property management app (410) to search and confirm property information as well as perform inspection and maintenance management tasks. The property management app (410) is installed so that the on-site user can access an app store, etc. and install it directly, or when tagging an empty tag or a tag with basic property information stored, the address of the app store where the property management app (410) is registered is automatically connected so that the app installation is performed.

The property management app (410) includes a field user information setting module (411), a field user confirmation module (412), a property information call module (413), a property information storage module (414), a property inspection management module (415), and a maintenance management module (416).

The on-site user information setting module (411) is a function for resolving the inconvenience of having to repeatedly input information about on-site users who perform the corresponding actions when saving, modifying, inspecting, or maintaining property information by inputting and storing on-site user information in the property management app (410). The on-site user information setting module (411) provides an interface for on-site users to input on-site user information, such as affiliation, rank, and name, after installing the property management app (410), and stores it in the property management app (410). When modifying, inspecting, or performing maintenance work using the property management app (410) in the future, it is automatically loaded so that it is transmitted together with the management history data.

The on-site user verification module (412) authenticates through the central web server (200) when saving, modifying, checking, and maintaining property information by entering the on-site password. The on-site user verification module (412) provides an interface for the on-site user to input the on-site password received from the administrator and transmit it to the on-site user authentication module (220) of the central web server (200) when modifying or saving information in the management database (220) after accessing the central web server (200) through the property information call module or maintenance management module (413 to 416) described below, so that the authentication process can be performed. In other words, only on-site users who have passed the on-site user authentication module (220) can modify or save information about property, and general users who do not know the on-site password are restricted to only viewing property information.

The asset information call module (413) is a module that calls the asset management number and asset basic information that are created and entered by the manager in the manager terminal (300) after newly introducing an asset and stored in the management database (210) of the central web server (200). The module calls the asset management number or asset name by entering it and searching for it, and then tags and stores the NFC tag (100) through the asset information storage module (414) described below.

The property information storage module (414) inputs and stores the property management number and basic property information in the NFC tag (100). The property information storage module (414) provides an interface for the on-site user to initially input information on the property searched and called using the property information call module (413) when a blank tag is attached to a newly installed property in the field, and stores it by tagging the NFC tag (100).

The property inspection management module (415) inputs inspection contents by item when inspecting the property to be managed regularly or periodically, adds user information previously input in the field user information setting module (411), creates management history data, and then transmits it to the management database (210) of the central web server (200). The property inspection management module (415) provides an interface for inputting inspection contents, and the management database (210) accumulates management history data by inspection date to create a management database (210) for inspection. The inspection management history data stored in the management database (210) is configured to display a list through the interface of the property management app (410) and to allow the user to check detailed inspection management history by date.

The maintenance management module (416) inputs maintenance details by item when maintaining the managed property and adds the user information previously input in the on-site user information setting module (411) to create management history data and then transmits the data to the management database (210) of the central web server (200). The maintenance management module (416) provides an interface for inputting maintenance details and the management database (210) accumulates management history data by maintenance date to build a management database (210) for maintenance. The maintenance management history data stored in the management database (210) is displayed as a list through the interface of the property management app (410) and is configured to allow the user to check the detailed maintenance management history by date.

The usage status of the NFC and mobile app-based asset on-site management system, to which the technology of the present invention is applied, having the configuration described above, is as follows. The following description is provided to explain preferred embodiments of the present invention, so the present invention is not limited to the following embodiments, and it will be appreciated that various modifications may be provided within a scope that does not depart from the scope of the present invention.

The NFC and mobile app-based asset on-site management system of the present invention is configured to eliminate complex and inefficient work procedures of the past by allowing on-site users in charge of inspection and maintenance of assets such as equipment and machinery installed on-site to process management history in real time on-site.

The on-site user installs the asset management app (410) on the on-site user terminal (400) that he/she carries, links it with the NFC tag (100) and the central web server (200), and performs the tasks of searching, modifying, checking, and maintaining asset information. In this case, it is natural that a on-site user who does not know the on-site password can only search simple asset information, and a on-site user who knows the on-site password can add or modify asset information.

In order to store basic information on assets in an empty tag mounted on newly installed assets on site, a field user terminal (400) is tagged. If the asset management app (410) is not installed, it automatically connects to the App Store or Google Play Store to install the asset management app (410). If the asset management app (410) is already installed, the asset management app (410) is executed.

When the asset management app (410) is first run, the on-site user information setting module (411) interface appears and requests the input of on-site user information, such as affiliation, position, name, etc. If the user is a simple user or external user who does not need to modify or save asset information in the future, the input process can be ignored.

When the property management app (410) is installed and the on-site user information is entered or the NFC tag (100) is tagged with the property management app (410) that skips the input process or the app is manually executed, if the tag is empty and the property basic information is not stored, the on-site user verification module (412) interface appears and requests the entry of the on-site password. The on-site password is a number that is created by the administrator through the on-site password setting unit (320) of the administrator terminal (300) and stored and managed in the on-site user authentication module (220) of the central web server (200), and is verbally delivered to the on-site users belonging to the management department. The on-site user who receives the on-site password from the administrator enters the on-site password and transmits it to the on-site user authentication module (220) of the central web server (200) for authentication. General users or external users who do not know the on-site password cannot use the property information call module (413) or the property information storage module (414).

Select the property information call module (413) and search by entering the property management number or the name of the newly installed property through the interface. The property management number is a number that the administrator creates through the property management number setting unit (310) of the administrator terminal (300), stores it in advance in the management database (210) of the central web server (200), and delivers it to the on-site user. The on-site user who receives the property management number from the administrator enters the property management number of the newly installed property and calls the property basic information that is stored in advance in the management database (210) of the central web server (200), such as the property name, specifications, installation date, supplier, and other information that does not change until the property is disposed of. The called property management number and property basic information are stored in the NFC tag (100) through the property information storage module (414).

When tagging a field user terminal (400) to an NFC tag (100) in which basic property information is already stored, if the property management app (410) is not installed on the field user terminal (400), it automatically connects to the App Store or Google Play Store to install the property management app (410), and if the property management app (410) is already installed, it executes the property management app (410).

In this case, the on-site user information setting module (411) can be executed to input on-site user information, such as affiliation, rank, name, etc., and if the user is a simple user or external user who does not need to modify or save asset information in the future, the input process can be ignored.

When the property management app (410) is executed, the on-site user verification module (412) interface is displayed and requests the input of a site password. A site user who has received a site password from an administrator, i.e. an internal user, enters the site password and transmits it to the on-site user authentication module (220) of the central web server (200) for authentication. General users or external users who do not know the site password cannot use the property inspection management module (415) and maintenance management module (416), and can only view information stored in the management database (210) of the central web server (200).

In order to create a management history during regular or periodic inspections of installed assets, the field user terminal (400) is tagged to an NFC tag (100) in which the asset management number and basic information are stored in advance.

The property management app (410) is automatically executed and the on-site user verification module (412) interface is displayed, requesting the input of the on-site password. The on-site user who has received the on-site password from the manager enters the on-site password and transmits it to the on-site user authentication module (220) of the central web server (200) for authentication. General users or external users without the on-site password cannot use the property inspection management module (415).

By selecting the property inspection management module (415), the inspection content is input through the interface, and the user information previously input in the field user information setting module (411) is added to create management history data, and the inspection management history data is stored in the management database (210) of the central web server (200). The property inspection management module (415) displays the inspection management history previously saved in the management database (210) as a list through the interface, allowing the user to check the details.

In order to create a management history when performing maintenance on installed assets, a field user terminal (400) is tagged to an NFC tag (100) in which the asset management number and basic information are stored in advance.

The asset management app (410) is automatically executed and the on-site user verification module (412) interface is displayed, requesting the input of an on-site password. A on-site user who has received an on-site password from the manager enters the on-site password and transmits it to the on-site user authentication module (220) of the central web server (200) for authentication. General users or external users without an on-site password cannot use the maintenance management module (416).

By selecting the maintenance management module (416), maintenance details are entered through the interface, and then the user information previously entered in the on-site user information setting module (411) is added to create management history data, and the maintenance management history data is stored in the NFC tag (100) and the management database (210) of the central web server (200). The maintenance management module (416) provides a list of maintenance management details previously stored in the management database (210) through the interface so that the user can check the details.

The NFC and mobile app-based asset field management system according to the present invention as described above provides an asset field management system that enables field workers to process asset information and management history data in real time using NFC and a mobile app when performing inspection and maintenance work at a site where assets are installed, thereby improving work efficiency and enabling more systematic and accurate history management.
