The present invention relates to an integrated maintenance management system, and more particularly, to an integrated maintenance management system that reduces procedures for receiving, inspecting, and demanding maintenance objects (or supplies) required by public agencies and the military, and reducing manpower. will be.

It is common for the military and public agencies to report the required maintenance items (or supplies) to senior agencies and take several steps to receive them. Normally, the request for supply of goods is received in sequence by two or more agencies, and the supplies for which supply requests have been made according to these steps are provided in reverse order by the same agency. This will be described with reference to FIG. 1.

1 illustrates a process in which maintenance objects required by the military maintenance unit are requested to be serviced and processed.

As shown, the maintenance of the maintenance object is required to maintain or supply the maintenance in the order of the use unit, maintenance unit, military governor, and munition, the military sends the requested maintenance object to the military branch, the military branch maintenance it As a unit, service units are handled in accordance with the process of providing them to the use unit where the initial service is requested. Documents for requesting maintenance from maintenance units to military branch offices are handed over to the higher authority (eg military branch offices) after obtaining approval from the billing authority. If maintenance is requested along these payment lines and maintenance is performed in reverse order, maintenance objects (e.g. tanks, artillery, and other combat equipment) that require maintenance may receive immediate maintenance due to administrative delays. Of course, there is a problem that the maintenance practitioner should spend a lot of time for the preparation and payment of administrative documents other than the maintenance work.

2 shows an example of administrative documents provided from the maintenance unit to the military branch.

The administrative documents include items for equipment holding unit, maintenance unit, registration number, stock number, serial number (S / N), name number, equipment name, receipt date, maintenance start date, maintenance completion date, and delivery date. In addition, the maintenance practitioner should fill out each item and submit it to the superior along with the approval documents. The administrative document shown is for one of the numerous parts that make up the air defense blister in 20 mm. If the number of parts required for air defense gun maintenance is large, the number of items to be filled out by the maintenance practitioner will increase, and administrative error will be proportional to the number of items to be increased It is obvious that the number of, and typos is increased. In this case, an error occurs in the maintenance object or part received by the maintenance unit, and the maintenance unit has to reclaim the incorrectly received maintenance object or part to the superior institution, which wastes time and effort for maintenance. Of course, it is possible to type in each item using a computer and submit it to a superior institution (eg, a military branch), but there is a limit in blocking an error caused by an increase in entry items.

As an alternative to this problem, a patent document has been disclosed for a system for applying an RFID tag to a maintenance object or a material (railroad vehicle) and managing the maintenance object or handling replacement of a material (railroad vehicle part). .

3 is a view for conceptually illustrating an integrated maintenance management system according to an embodiment of the present invention.

The illustrated integrated maintenance management system 100 acquires tag information of a radio tag (for example, an RFID tag) attached to a maintenance object through a terminal 10 provided in a maintenance unit of a military unit, and obtains a category of the acquired tag information. After grasping, the terminal 10 provides a list of parts to be repaired to the terminal 10, and the terminal 10 receives a maintenance object corresponding to the list of parts to be repaired and a request for maintenance of the parts to a superior institution (eg, a maintenance unit, a military branch, And the servers (reference numerals 500, 600, and 700, respectively) provided in the military service company, etc., simplify the existing maintenance procedure described with reference to FIG. At this time, the integrated maintenance management system 100 is a tree for the maintenance object according to the tag information of the maintenance object read out from the tag reader 11 and the maintenance object (usually a part) of the lower category which makes the maintenance object an upper category. By generating a parts list of the maintenance target having a structure and providing it to the terminal 10, an integrated maintenance management system based on the image is constructed.

The parts list of the maintenance target having the category form will be described with reference to FIGS. 5 and 6 together. The parts list of the maintenance target shown in FIGS. 5 and 6 allows the operator who operates the terminal 10 to request maintenance by simply selecting a maintenance target and parts to be maintained through an input device such as a mouse. The parts list of the maintenance target shown in FIG. 5 classifies maintenance targets (parts) according to categories ranging from detection tracking devices, communication devices, bodywork, and other devices based on the highest concept of "thousand horses (short-range guided weapons)". When the operator of the terminal 10 selects a category (eg, a detection tracking device) to be maintained, maintenance objects (parts constituting the detection tracking device) included in the selected category (for example, a turret) are displayed in a lower category. The process of requesting maintenance or dissemination of a maintenance target object requiring maintenance using a category will be described later in detail. The terminal 10 selects a maintenance target (or parts, hereinafter omitted) that requires maintenance or replenishment through a parts list of the maintenance target having a tree structure and provides the integrated maintenance management system 100 to the maintenance target maintenance. Save material and human resources. Integrated maintenance management system 100 is linked to the maintenance unit server 500, military branch server 600, and military personnel server 700, through each server (500 ~ 700), the maintenance of the object and the supply information Acquire it. Accordingly, when the maintenance or replenishment request for the maintenance object occurs through the terminal 10, the integrated maintenance management system 100 can find a place where the requested maintenance or replenishment can be performed and notify the terminal 10, When the terminal 10 checks this and requests maintenance or replenishment, the terminal 10 may request maintenance or replenishment where the corresponding maintenance object is held. Of course, the integrated maintenance management system 100 preferably requests the supply or maintenance of each server (500, 600, 700) according to the format required for maintenance or dissemination.

Here, as the superior institution server described in this drawing, the military branch server, the military investigation server, and the server of the maintenance unit are mentioned, but this is only an example, and due to the characteristics of the military, the superior authority may be changed or the name may be changed. have. The main body of the higher-level engine server 500, 600, and 700 referred to in the present invention means a server provided in a higher-level institution capable of providing or replacing necessary maintenance items in response to a request for servicing a maintenance object. . This is found to apply equally throughout the present invention.

The maintenance database 150 records information on a maintenance object requested to be maintained by the terminal 10, and further includes information described below.

1) Image of the maintenance object corresponding to the category,

2) information of maintenance object to make up category,

3) gratuitous AS information for each maintenance object;

4) Paid AS information for each maintenance object, and

5) Maintenance history for each maintenance object.

6) Proper replacement time for each maintenance object.

Here, the integrated maintenance management system 100 having the maintenance database 150 is connected to the terminal 10 and the servers 500, 600, and 700 by a dedicated network because all the information necessary to maintain the maintenance object is concentrated. It is preferable. In addition, the integrated maintenance management system 100 encrypts data transmitted to and from the terminal 10 and the servers 500, 600, and 700, and the encryption method is changed every mutually agreed period (for example, from one day to one month). Can be.

4 is a block diagram illustrating an example of the integrated maintenance management system illustrated in FIG. 3.

The illustrated integrated maintenance management system includes a category setting module 110, an image matching module 120, a maintenance request module 130, a maintenance management module 140, and a maintenance database 150. The illustrated integrated maintenance management system 100 is connected to the terminals 10a to 10n of each use unit through a network, and the maintenance request and the supply request for the maintenance target are generated through each use unit terminals 10a to 10n. City, and notifies the corresponding higher authority server (500, 600, and 700). At this time, the terminal 10a 10n is connected to a tag reader for reading a radio tag (for example, an RFID tag), and a radio tag is attached to each maintenance object. In the radio tag, a serial number or a unique number for specifying each maintenance object is described, and the radio tag may be either an active type, a passive type, or a sensor type. Here, the terminals 10a to 10n may be terminals provided on any one side of the maintenance unit, the military governor, and the military commander, in addition to the use unit, but for convenience of explanation and understanding, the terminal provided in the use unit is described below. Explain it as a guide.

The terminals 10a to 10n read a tag information on a maintenance target by bringing a tag reader (not shown) closer to a wireless tag mounted on the maintenance target and provide it to the integrated maintenance management system 100.

The category setting module 110 determines the category of the maintenance target corresponding to the tag information in response to the tag information provided by the terminals 10a to 10n, and determines the determined category and the lower category to determine the maintenance target of the tree structure. Create a parts list. The generated parts list of the maintenance target will be described with reference to FIGS. 5 and 6 together.

5 shows an example of a list of parts to be repaired provided from the integrated maintenance management system 100 to the terminals 10a to 10n. As shown in the drawing, the parts list to be maintained includes the maintenance object according to the tag information read by the tag reader 11 as a top category, and lists subcategories belonging to the top category in a tree structure. Sub-category belonging to the highest category is a component constituting the maintenance object of the highest category, when the tag reader 11 transmits the tag information about the sky horse (short-range guided weapon) to the integrated maintenance management system 100, integrated maintenance The management system 100 is a functional characteristic of the maintenance object constituting the cheonma (short-range guided weapons), such as detection tracking device, communication device (fire control device), the body, and other devices constituting the cheonma (short-range guided weapon). It is divided into a plurality according to. Each sub-category partitioned is located in each node of the tree structure, and the operator of terminals 10a to 10n can be selected by using an input device such as a mouse. Expanded and displayed. 6 shows another example of a parts list for maintenance. As shown, when the operator selects the "detection tracking device" category shown in FIG. 5, a display device (for example, CRT, LCD, PDP, etc.) provided in the operator's terminal (for example, any one of reference numerals 10a to 10n). ) Displays an image of the detection tracker category, and the operator can use the displayed image to view an image of a maintenance object that he / she wants to request for maintenance (or supply). Through this, when an operator requests maintenance or dissemination to the integrated maintenance management system 100, an error occurring in the process of selecting a maintenance object may be reduced. To this end, one side of the display device displays an image corresponding to the maintenance object selected by the operator, and a pre-view menu 5 for selecting an image, and a pre-view menu 5. At the bottom of the display, a selection menu (2) is displayed to help the operator select a maintenance target. The selection menu 2 includes an image 6 for the maintenance object selected by the operator, a maintenance request menu 3, a replenishment request menu 4, and a cancel menu 5.

The category setting module 110 refers to the tag information provided by the terminals 10a to 10n to make the maintenance object corresponding to the tag information as the highest category, and to set the maintenance object (parts) belonging to the highest maintenance object as the lower category. Create a parts list for maintenance. At this time, the category setting module 110 receives the information corresponding to the tag information from the maintenance database 150 having data for each maintenance object and an image, and generates a parts list of the maintenance target through this. The image matching module 120 matches the image to the parts list of the maintenance target generated by the category setting module 110. The image means the image of the maintenance object of the top category and the sub category belonging to the top category according to the tag information, and combines the image with the parts list of the maintenance target or includes the path to the image in the parts list of the maintenance target. You can.

If the image and the category are directly combined, the operator of the terminals 10a to 10n encounters a form in which an image is added to each of the parts list to be maintained, and a path to the image is included in the parts list to be maintained. In the present invention, only the maintenance object selected by the operator as an input device (eg, a mouse or a keyboard) to request maintenance is displayed on the display device as an image. The maintenance request module 130 provides a terminal to which the terminal 10a to 10n is finally selected by using the parts list of the maintenance target to the advanced engine server 500 to 700.

The maintenance management module 140 manages the maintenance history for the requested maintenance object through the terminals 10a to 10n. Maintenance history includes consumables that need to be replaced at regular intervals, such as the date, frequency, cause of failure, current status, free AS period, paid AS period, status of stocks of superior institutions, and parts constituting equipment (eg, cheon-ma). It shows information on when to replace the tank, and information about maintenance personnel and units. Preferably, the maintenance management module 140 includes a maintenance history management module 141, equipment inventory inquiry module 142, AS management module 143, and preventive maintenance module 144.

The maintenance history management module 141 records the maintenance history for the maintenance object (or supply) for which maintenance is requested, the maintenance history of the parts constituting the maintenance object in the maintenance database 150, and the terminals 10a to 10n for the maintenance object. When the inquiry is requested, the corresponding maintenance information is inquired in the maintenance database 150 and provided to the terminals 10a to 10n. Maintenance history management module 141 is based on the history (maintenance, outsourcing maintenance, replacement, disposal, etc.), maintenance date and time, the serial number of the maintenance object, the belonging, status, maintenance of the maintenance object. The information about the maintenance, the number of repairs, the maintenance result, and the information regarding the AS period for a fee or not are recorded in the maintenance database 150 or read from the maintenance database 150 and provided to the terminals 10a to 10n. The equipment inventory inquiry module 142 accesses the integrated maintenance management system 100 and the network of higher-level institutions (for example, reference numeral 500) connected to the network, and inquires the stocks of the higher-level institutions that supply or repair the maintenance items, and whether they are held. . The inquired result is provided to the terminals 10a to 10n or other high-ranking institution servers (for example, reference numerals 600 and 700), and the operator of the terminals 10a to 10n can determine whether maintenance on the maintenance target is possible. have. The AS management module 143 determines whether the maintenance object and the AS-time period set for each of the components constituting the maintenance object and the maintenance object requested for maintenance through the terminals 10a to 10n are determined. In general, maintenance objects such as cheon-ma (short-range guided weapons) have different service lifespans of the parts constituting the cheon-ma, and a fixed AS period is determined differently according to the service life. According to these characteristics, the contract concluded with the company supplying the maintenance object specifies the free AS period for each part, but it is difficult to identify all the AS periods of many parts and apply them to maintenance. In general, the case of the cheonma (short-range guided weapons) to determine the date of manufacture through the name plate (serial number is written) attached to the body, it is common to proceed to the AS on the basis of the manufacturing date of the cheonma (short-range guided weapon). At this time, even if a part of the internal parts constituting the cheonma is included with a long free AS period is often overlooked by the side performing the maintenance, AS that can be processed free of charge is often treated as paid. The maintenance database 150 includes information on the AS period of the parts included in each maintenance object, and the AS management module 143 refers to the AS information provided in the maintenance database 150, and the maintenance object is requested for maintenance. It judges whether or not this free AS process is performed, and notifies the result of the determination to the superior institution server 500 to 700 or the terminals 10a to 10n.

The preventive maintenance module 144 may refer to an appropriate replacement time for each maintenance object provided in the maintenance database 150, and preventive maintenance items set for each maintenance object, and parts for which an appropriate replacement time has passed, or an appropriate replacement time (for example, Judgment of preventive maintenance (usually consumables) is estimated at the time of exceeding 90% of the service life. As a result of determination, if an appropriate replacement time of the components constituting the maintenance object has passed or is close to (for example, exceeding 90% of the proper replacement cycle), it is automatically notified to the maintenance request module 130, and the maintenance request module 130 ) Requests the supply (or replacement) of the corresponding parts to the server 500, 600, and 700 of the superior institution with reference to the information notified in the preventive maintenance module 144. In addition, the preventive maintenance module 144 generates a preventive maintenance history by referring to the matters notified to the superior institution servers 500, 600, and 700, writes it in the form of a file, and records and manages it in the database 150. .

FIG. 7 illustrates an example of an interface displayed in response to an item selected by an operator of the terminal (eg, a detection radar) in the parts list to be maintained in FIG. 6.

In the drawing, when the terminal operator selects any one of the maintenance objects (eg, detection radar, guided missile, and tracking electro-optical device) located at the node constituting the parts list for maintenance, the maintenance case (A) is selected for the selected maintenance object. A menu for querying, and technical reference is displayed, and the selected item among the maintenance case (A) and the technical reference is displayed on one side of the parts list to be maintained so that the maintenance staff can use it. Preferably, the operator places an input device such as a mouse (detection radar in the drawing), and when the user enters a predetermined key (for example, the "L" key), the item where the mouse cursor is located (detection radar in the drawing). It is possible to display maintenance cases for. In addition, the user can call the menu by pressing the right button of the mouse after the mouse is close to the item, and the selected menu can be used to select the maintenance case (A) or technical reference. In this case, the illustrated interface should be set such that a menu for calling the maintenance case A or technical reference in response to the right button of the mouse is provided. In the drawing, maintenance cases for the detection radar are indicated in ① to ③, and data that can guide the maintenance of the detection radar are displayed. To this end, the maintenance database 150 should be provided with data on maintenance cases (A), and technical reference.

9 illustrates an example of historical information provided to the terminal by the integrated maintenance management system 100 in response to tag information provided to the integrated maintenance management system through a tag reader.

FIG. 10 shows an example in which a maintenance practitioner registers a maintenance history after processing maintenance on a maintenance object in terminals 10a to 10n.

11 illustrates an interface for registering a result processed through a maintenance window or a subcontractor when a maintenance request is requested through a maintenance window or an outsourcing (maintenance by a maintenance object supplier).

First, referring to FIG. 8, the maintenance practitioner reads the tag information by approaching the tag reader 11 to the wireless tag attached to the maintenance object and provides the integrated maintenance management system 100 to query the registration specification for the maintenance object. can do. The result is as shown in Figure 9, the maintenance practitioner various specifications of the maintenance target to be maintained (eg equipment serial number, defense unit number, equipment holding unit, inventory number, defense equipment code, model number, manufacturer information, And production date, etc.). In addition, the maintenance practitioner, as shown in FIG. 10, can grasp the reason why the maintenance target was previously maintained, and a history. The history shown in FIG. 10 may be registered separately by the maintenance practitioner after the maintenance of the maintenance object, and may also modify the registered information.

12 is a view for explaining a processing example for a maintenance object that is difficult to process with a radio tag.

The illustrated figure shows an air conditioner pipe mounted on a transport vehicle, the serial number of which is engraved intaglio at one end of the pipe. In order to query the maintenance object or parts belonging to the maintenance object in the form shown in the interface shown in FIG. It does not wear out and has excellent durability.

13 is a view for explaining another example of processing for a maintenance object that is difficult to process with a radio tag.

The figure shown shows a barcode attached to the air conditioner pipe. This ensures that every single part of a maintenance object can be managed in an integrated maintenance management system without the need for radio tags. In order to minimize the manual labor by the maintenance practitioner, the tag reader 11 is preferably embedded with a barcode reader. In addition, the bar code mounted to the air conditioner pipe is manufactured in the form of a name plate, and is preferably coupled to the maintenance object according to any one of screwing, welding, and bonding. In addition, if the background color of the maintenance target is white, the bar code may be directly printed on the background color.

14 shows a form in which a radio tag is mounted on an air conditioner pipe.

As shown, when the radio tag is attached to all parts, the air conditioner pipe, which is one of a number of parts constituting the transport vehicle, is also equipped with an RFID radio tag, through which the integrated maintenance management system 100 is completed ( The information on all the parts constituting the maintenance object) can be read and managed by the tag reader 11.
