  In this embodiment, as one aspect, when an operator carrying an HHT searches for an article while walking in a passenger aircraft cabin, the walking speed, RFID tag detection timing, walking direction, and the like are guided. For articles that require RFID tag detection and visual confirmation, the radio wave output is automatically weakened to narrow the detection range, and the operator is forced to approach the article to a visible distance.

  In addition, when a plurality of operators each search for an RFID tag using HHT, the HHT cooperates to guide a person to a position where the RFID tag can be efficiently detected.

  Thus, when searching for the RFID tag attached to the equipment or parts of the aircraft, efficiency is improved by guiding a person to the place where the RFID should be. More specifically, it is realized as follows as an example.

1) Affix an RFID tag to aircraft equipment.
2) The position of the tag attached to the aircraft equipment is stored in the server and downloaded to the HHT before the RFID search.
3) When an RFID tag is detected by sharing a plurality of HHTs, communication is performed between the HHTs, and a search range for each HHT is determined based on the downloaded information. The sharing is determined in consideration of the walking distance, the number of detected RFID tags, and the like so that the search can be performed efficiently. You may make it a learning type of past results.
4) Each HHT guides a person to a position where HHT is shared. As an example of the guidance method, a guide map in the aircraft is displayed on the HHT screen, and a search start position and a search direction of the RFID tag are displayed in the guide map.
5) The operator detects the RFID tag according to the guidance of HHT.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a conceptual diagram showing an example of the configuration of an article search system that implements an article inspection method, a portable terminal apparatus, and a control program for the portable terminal apparatus according to an embodiment of the present invention.

2 and 3 are conceptual diagrams showing an example of the configuration of information used in the article search system according to the embodiment of the present invention.
In the present embodiment, as an example, when the equipment search system 10 as an article search system is applied to a search (inspection) operation for articles such as life vests and oxygen generators for each seat deployed in passenger cabins. Will be explained.

  As illustrated in FIG. 1, the equipment search system 10 of this embodiment includes a server 20 and a plurality of RFID tag search devices 30. Hereinafter, when referring to the individual RFID tag search devices 30, they may be described as the RFID tag search device 1 and the RFID tag search device 2.

  The server 20 is configured by a computer system, and includes a CPU 21 as a central processing unit, a memory 22, an external storage device 23, and a communication device 24.

  The memory 22 is used as a main memory, and stores a control program 80 and data executed by the CPU 21.

  The CPU 21 executes the control program 80 to realize processing illustrated in a flowchart and the like described later.

  The external storage device 23 stores, as a database, equipment management information 40 as described later for use by each RFID tag search device 30.

  The communication device 24 has a communication function for performing wireless information communication with each RFID tag search device 30.

  On the other hand, each RFID tag search device 30 is a so-called inspection terminal (handheld terminal: HHT), which is an information terminal constituted by a small computer system. A dedicated HHT may be used, or a general-purpose mobile phone device may function as an HHT by software.

  That is, the RFID tag search device 30 includes a CPU 31, a memory 32, an RFID reader 33, a communication device 34, a display 35, and an input device 36.

  The CPU 31 executes a control program 81 stored in the memory 32 as the main memory, thereby realizing a control operation exemplified by a flowchart described later.

  The memory 32 functions as a storage device that stores the control program 81 and various information received from the server 20.

  The RFID reader 33 performs processing for recognizing an RFID tag by exchanging information by short-range wireless communication with the RFID tag provided in the equipment to be searched (in this case, a life vest or an oxygen generator). I do.

The communication device 34 performs information communication with the server 20.
The display 35 performs visualization display of various types of information as described below for an operator who possesses the RFID tag search device 30.

  The input device 36 is used by an operator to input an instruction to start searching into the RFID tag searching device 30. When the display 35 is a touch panel, the input device 36 can be implemented as an icon arranged on the touch panel.

The equipment management information 40 stored in the server 20 includes an aircraft body number 41, aircraft map information 42, in-map distance information 43, and RFID information 44.
The aircraft body number 41 is a number for identifying each passenger aircraft.

  The aircraft map information 42 is image information of a guest room to be searched, and the in-map distance information 43 is coordinate information of facilities such as seats in the guest room.

  FIG. 2 is a conceptual diagram illustrating an example of an aircraft map and intra-map distance information. The aircraft map information 42 includes the positions of a plurality of seats 42a and utility areas 42b, and a passage 42c between them as graphic information.

  The intra-map distance information 43 indicates the positions of the seat 42a, the utility area 42b, and the passage 42c with coordinates.

FIG. 3 is a conceptual diagram illustrating a configuration example of RFID information.
The RFID information 44 includes a management number 44a, an equipment name 44b, an RFID search filter 44c, an RFID position 44d, a radio wave intensity 44e, a visual confirmation necessity 44f, and a remark 44g for each equipment.

  The RFID position 44d includes an X coordinate 44d1, a Y coordinate 44d2, and an arrangement location 44d3.

  The meaning of dBm in the radio wave intensity 44e is, for example, 0 dBm = 1 mW, 20 dBm = 0.1 W, 27 dBm = 0.5 W, and 30 dBm = 1 W. According to the information set in the remark 44g, for example, when the equipment is installed on the ceiling and cannot be brought close to the RFID tag, the radio wave intensity 44e for detecting the equipment (RFID tag) is relatively high. Is set.

  In the present embodiment, each RFID tag search device 30 is provided in each seat or the like by guiding the operator by displaying the above-described aircraft map information 42, in-map distance information 43, etc. on the display 35. Search (inspection) for equipment (RFID tags).

  As an example of guidance of the operator by the RFID tag search device 30 in the inspection work, the life vest and the oxygen generation device in the aircraft cabin are searched using the RFID tag attached to each.

FIG. 4 is a conceptual diagram showing a method of guiding an operator by the RFID tag search apparatus according to the present embodiment.
The aircraft map information 42 and the in-map distance information 43 are displayed on the display 35 of the RFID tag search device 30.

Since the life vest is stored under the individual seats 42a, the operator is guided to go around the individual seats 42a.
When the number of rows of the seats 42a is large and the life vest is installed at a distance from the passage 42c, the seats 42a are guided to pass through the seats 42a to detect the RFID tags.

The characteristics when the operator is guided by the RFID tag search device 30 of the present embodiment are as follows.
Information on the movement path 35d and the current position 35c is displayed on the display 35 of the RFID tag search device 30 as guidance for the direction in which the operator should go.

  Automatically instruct the search trigger timing. Or automatically send out radio waves and search.

  Tell the operator how fast to walk. That is, the search time is predicted, and the speed at which a plurality of RFIDs can be searched without omission is indicated.

  When visual confirmation is unnecessary, the radio wave radiated from the RFID reader 33 is automatically strengthened to widen the RFID search range.

  On the other hand, for items that require visual inspection, the radio waves radiated from the RFID reader 33 are relatively weaker than those in the case where visual confirmation is not required, the detection range is narrowed, and the equipment is provided to a distance that can be viewed by the operator. Guide you to approach.

  That is, in the RFID tag search device 30 of the present embodiment, the strength of the radio wave of the RFID reader 33 is controlled according to the inspection attribute such as the necessity of visual confirmation on the equipment, and the inspection according to the inspection attribute is performed. Next, the operator who has the RFID tag search device 30 is guided.

Hereinafter, an example of the operation of the present embodiment will be described with reference to a flowchart and the like.
First, an example in which the server 20 determines a search route in the cabin of each RFID tag search device 30 will be described.

FIG. 5 is a flowchart illustrating an example of search path determination processing by the server.
First, the server 20 communicates with the RFID tag search device 30 (HHT) and acquires the HHT input information 50 from the HHT (step 201).

  The HHT input information 50 includes information on the number of HHTs 51 used for the RFID search, the search start position 52, the aircraft body number 53, and the search target equipment 54.

  Next, the server 20 determines the RFID search path 61 (movement path 35d) of each HHT from the HHT input information 50 obtained from the HHT and the above-described equipment management information 40 stored in the server 20 (step 202). ).

  Next, the server 20 notifies the RFID search information 60 including the RFID search path 61 to the HHT (step 203).

  In this case, the RFID search information 60 includes aircraft map information 42, intra-map distance information 43, RFID position 44d, RFID response distance (radio wave intensity 44e), necessity of visual confirmation 44f, and RFID search path 61.

  The determination of the RFID search route 61 by the server 20 in the above-described step 202 can be determined from the map by, for example, determining the search order for each HHT number in advance on the aircraft map information 42. .

  In this case, as shown in FIG. 6 and FIG. 7, the search order for each HHT number is determined in advance on the aircraft map information 42.

  FIG. 6 shows an example of searching with one RFID tag searching device 30 (HHT). In this case, one RFID search path 61 and a search start position 52 are set in the aircraft map information 42.

  FIG. 7 shows an example of searching with two RFID tag searching devices 30 (HHT). In this case, two RFID search paths 61 and a search start position 52 are set corresponding to the two RFID tag search devices 30.

  As a method other than the examples of FIGS. 6 and 7 described above, the RFID search path 61 may be automatically calculated from the arrangement of the seats 42a and the like of the aircraft map information 42. A method for calculating a route is a well-known technique, and as an example, there is a technique disclosed in Japanese Patent Laid-Open No. 2002-310702.

  In the above description, the method of determining the RFID search path 61 by the server 20 and distributing it to the RFID tag search apparatus 30 is exemplified. However, the RFID search path 61 is determined on the RFID tag search apparatus 30 (HHT) side. Also good.

  When the RFID search path 61 is determined by the HHT, the HHT may have information necessary for path determination or may be downloaded from the server 20.

  In the case of using a plurality of RFID tag search devices 30 (HHT), the server 20 determines sharing, or performs communication between the plurality of HHTs and determines each HHT in the RFID search path 61.

Next, an example in which each RFID tag search device 30 performs guidance of an operator in an RFID tag search operation using the RFID search path 61 determined as described above will be described.
8 and 9 are flowcharts showing an example of the operation of the RFID tag search apparatus according to the present embodiment. 8 and 9 are connected by circles A and B, and are referred to as one flowchart.

  The processing of the flowcharts of FIGS. 8 and 9 is realized by the CPU 31 executing the control program 81 installed in the RFID tag search device 30.

  The CPU 31 of the RFID tag search device 30 reads from the memory 32 the RFID search information 60 received from the server 20 in step 203 and the information of the RFID search filter 44c designated by the operator (step 301).

  The following aircraft map information 42, search start position 52, and RFID search path 61 information are displayed on the screen of the HHT display 35 (step 302).

  FIG. 10 is a conceptual diagram showing an initial screen of the display 35 before the start of inspection, and FIG. 11 is a conceptual diagram showing a screen of the display 35 during inspection.

  As illustrated in FIG. 10, on the initial screen, in addition to the aircraft map information 42 and the intra-map distance information 43, the current position vicinity equipment list 35a, the walking speed display 35b, the current position 35c, and the movement are displayed on the display 35. A path 35d, an undetected area 35e, a detected area 35f, and a priority detection area 35g are displayed.

  Here, the priority detection area 35g indicates an area that can be searched more efficiently if it is detected by going backward rather than moving forward if it has passed without being detected during the RFID search. The operator can perform the inspection work efficiently without omission by returning and performing re-detection according to the display of the priority detection area 35g.

  In the current position vicinity equipment list 35a, equipment name 44b, RFID position 44d, and result 73 are recorded.

  In the case of the search screen shown in FIG. 11, the aircraft map information 42 and the intra-map distance information 43 are displayed on the display 35. The aircraft map information 42 includes a current position 35c and an arrow moving path 35d (RFID search). The latest state of the path 61), the undetected area 35e, the detected area 35f, and the priority detection area 35g is displayed.

Note that the detected equipment is not displayed in the current position vicinity equipment list 35a on the screen being searched.
Information on the RFID tag to be detected is acquired (step 303).

  A filter for selectively designating equipment to be searched is set (eg, life vest) (step 304). For example, when “life vest” is designated as the filter, even if the life vest and the oxygen generator are mixed on the site, only the life vest is the search target.

It is determined whether the RFID tag to be detected needs to be visually confirmed (step 305).
Then, when visual inspection is unnecessary, the value of the radio field strength is obtained from the radio field strength 44e of the RFID information 44, set as the radio field strength of the RFID reader 33, the RFID tag is searched, and the result is recorded (step 306). .

  On the other hand, if it is necessary to visually check, the value of the radio wave weakness is acquired from the radio wave intensity 44e of the RFID information 44, set as the radio wave intensity of the RFID reader 33, the RFID search is performed, and the result is recorded (step 307).

  That is, when the visual inspection in step 307 is necessary, the radio wave intensity of the RFID reader 33 is set to be relatively weak. Therefore, in order to detect the RFID tag by the RFID tag search device 30, the RFID tag search device 30 is possessed. The operator needs to be closer to the RFID tag (equipment), and as a result, the operator is guided to approach the visible position of the fixture.

  Next, it is determined whether or not the search has been completed (step 308). If the search has been completed, the search result is transmitted to the server 20 (step 309) and the process ends.

  On the other hand, if not completed, communication from another HHT or server 20 is accepted (step 310).

  Then, it is determined whether or not there is communication from another HHT or server 20 (step 311), and if there is communication, it is determined whether or not there is a change in assignment (step 312).

  If there is a change in assignment, the remaining number (RFID tag (equipment) that has not been inspected) is transmitted to another HHT or server 20 (step 313), and the reassignment is sent from the other HHT or server 20 Receive (step 314).

  If there is no communication in step 311 described above, or if there is no sharing in step 312 described above, step 313 and step 314 are not executed.

  Thereafter, it is determined whether or not the remaining RFID tags to be searched are small (step 315). If it is determined that there are few RFID tags, the remaining number (RFID tags (equipment) for which inspection has not been completed) is transmitted to another HHT or the server 20. (Step 316), and the reallocation is received from another HHT or the server 20 (Step 317).

  FIG. 12 is a conceptual diagram illustrating a screen example of the display 35 including the detection result 70 during the search (inspection). In the detection result 70, an equipment name 71 (equipment name 44b), an RFID position 72 (RFID position 44d), and a result 73 are recorded. In this result 73, the type of detection / non-detection and other HHT sharing is displayed.

  Thereafter, information such as the RFID search path 61 for the remaining portion or reassignment is displayed on the display 35 to guide the operator, and the RFID search is continued according to this guidance (step 318).

  Then, it is determined whether or not the RFID tag has been detected (a plurality of tags can be detected simultaneously) (step 319). If the RFID tag can be detected, information on the detected RFID tag is stored in the memory 22 (step 320). .

  Next, the position of the RFID tag search device 30 (HHT) in the aircraft map information 42 is estimated from the information of the detected RFID tag detected in step 320 (step 321).

  Note that it is a well-known technique to estimate the position of the RFID tag search device 30 (HHT) from the detected position of the RFID tag. For example, the technique disclosed in Japanese Patent Application Laid-Open No. 2004-21978 is known.

  Next, it is determined from the estimated position of the RFID tag search device 30 (HHT) and the recorded inspection result information whether or not the RFID tag has passed without being detected (step 322).

  If it is determined that the vehicle has passed, a warning is given that the device has passed an uninspected RFID tag by a display on the display 35 or a sound from a speaker (not shown) (step 324). “Slow” is output to the walking speed display 35b of the display 35 (step 325).

On the other hand, if it is determined in step 322 that the vehicle has not passed, a walking speed display “currently fast” is output to the display 35 (step 323).
Thereafter, the above steps 303 and after are repeated.

With reference to FIG. 13 and FIG. 14, an example of the sharing change process in the above-described step 311 to step 318 by the intervention of the server 20 will be described.
FIG. 13 is a flow chart for explaining an example of search sharing change processing by server intervention in the equipment search system of the present embodiment.

  FIG. 14 is a conceptual diagram illustrating an example of a screen of the RFID tag search device in the search sharing change process in the equipment search system of the present embodiment.

  In the flowchart of FIG. 13, the portions related to the change of assignment in the flowcharts of FIGS. 8 and 9 described above in the RFID tag search device 1 and the RFID tag search device 2 are extracted and described.

  In the following, as an example, a case will be described in which the server 20 changes the sharing of the search range of equipment between two RFID tag search devices 30 (RFID tag search device 1 and RFID tag search device 2). The sharing change may be directly executed between the plurality of RFID tag search devices 30.

  In this case, the operations in steps S <b> 2 to S <b> 12 for changing the sharing are realized by the CPU 21 executing the control program 80 in the server 20 when the server 20 performs the sharing change.

  Further, when the sharing change is performed between the RFID tag search devices 30, the CPU 31 in the RFID tag search device 30 on the side of receiving the change request executes the control program 81.

Below, about the part which communicates with the server 20 grade | etc., The code | symbol of step S1-step S13 is newly attached | subjected and the part relevant to a share change is demonstrated.
First, when the remaining RFID tags to be searched are small, the RFID tag searching apparatus 1 transmits the remaining number to the server 20 (step 316) (step S1).

  The server 20 accepts communication from the RFID tag search device 1 (step S2), and stores the detection result of the RFID tag search device 1 (step S3).

  When the remaining unsearched equipment in the RFID tag search device 1 is small, the remaining RFID tag search device 2 is requested to transmit the rest with “assignment changed” (step S4).

  In response to this, the RFID tag search device 2 accepts communication from the server 20 (step S5) (step 310), and transmits the remaining number of the RFID tag search device 2 in response to the server 20 (step S6) (step S6) (step S6). 313).

The server 20 accepts communication from the RFID tag search device 2 (step S7), and stores the equipment detection result in the RFID tag search device 2 (step S8).
Then, the server 20 executes reassignment of the share of equipment search (step S9).

An example of the reallocation calculation in the server 20 is as follows.
An average value of the remaining number of the entire RFID tag search device 30 (in this case, the RFID tag search device 1 and the RFID tag search device 2) is calculated.

  Then, reallocation is performed to the individual RFID tag search device 1 and the RFID tag search device 2 so that the remainder of each RFID tag search device 30 becomes an average value.

  When the average value does not become an integer, the allocation for the RFID tag search apparatus 30 with a small remaining number before reassignment is rounded up. That is, it is assumed that the RFID tag search device 30 with a small number of remaining cases searches quickly.

  The server 20 transmits the reassignment result obtained as described above to the RFID tag search device 1 (step S10), and the RFID tag search device 1 receives the reassignment from the server 20 (step S11) ( Step 317).

  Similarly, the server 20 transmits the reassignment result to other RFID tag search devices 2 (step S12).

  The RFID tag search device 2 receives this reassignment (step S13) (step 314).

FIG. 14 shows a display state of the display 35 in the RFID tag search apparatus 1 after the above-described reallocation.
In the detection result 70 (result 73) of the RFID tag search device 1, for example, five cases are assigned as undetected to the RFID tag search device 1 from among the initial assignments of the RFID tag search device 2 as a result of the reassignment. has been changed.

  Further, in the aircraft map information 42 displayed on the display 35 of the RFID tag search apparatus 1, the additional portion 35h is displayed so as to be identifiable by hatching or the like.

  As described above, according to the equipment search system 10 of the present embodiment, inspection management work for articles having various inspection attributes can be efficiently performed using the RFID tag.

  For example, it is possible to efficiently search for equipment provided in an aircraft or the like by reading an RFID tag attached to the equipment.

  Furthermore, in the inspection management work of articles having various inspection attributes such as necessity of visual storage, when visual confirmation is necessary, the operator can be guided to approach the equipment to a visible position, and the RFID tag The operator who has the search device 30 can be accurately guided to perform the inspection work efficiently.

  In addition, when a plurality of RFID tag search devices 30 cooperate to search for equipment, according to the progress of the search work in each RFID tag search device 30, the assignment can be dynamically changed during the work. It is possible to reduce the time required for the entire work, and to search for equipment more efficiently.

Furthermore, managing equipment with RFID tags has the following advantages, for example.
1) By storing the maintenance information of equipment and parts in the RFID tag, the state management of the parts becomes easy. For example, the results of inspections and repairs before flight can be referred to at the airport / maintenance station after flight.
2) It can be expected to increase the efficiency of pre-flight inspection and reduce the required time by using it to check the presence of articles in the cabin (eg, life vest / oxygen generator).
