Description

  Embodiments described herein relate generally to a management apparatus and a program.

Along with the reduction in cost of RFID tags, it is expected that technology for managing articles and the like using RFID tags will become increasingly popular in the future.
For example, a technology for recognizing articles and the like using an RFID tag and grasping their position exists as an existing technology.

  However, in the prior art, in order to enable the reader to read the RFID tag attached to the management target article, for example, it is necessary to align the management target article and place it on a carriage. For example, the RFID tag may not be correctly recognized depending on how the articles to be managed are arranged. When working at a distribution base (for example, a base for shipping or relaying parcels such as parcel delivery), when the person in charge places the luggage on the carriage, the person in charge of the RFID tag attached to the luggage In some cases, work efficiency may be reduced by taking care to be recognized by the reader. Further, when the gate type RFID reader is used, there is a problem that the degree of freedom of the work flow line of the worker is reduced and the degree of freedom of movement of the carriage on which the load is loaded is lowered. As a result, in some cases, it is difficult to grasp information such as luggage.

  In addition, the work at the distribution bases and the like is currently under the manual work of the person in charge. In order to improve the efficiency of the entire business, for example, information on packages (objects to be managed), information on physical distribution containers for storing and temporarily storing packages, and information on workers in charge, It is also desirable to accurately and accurately grasp and obtain numerical data.

(First embodiment)
FIG. 1 is a perspective view showing a schematic configuration of a shoot field (also referred to as “chute” or “sorting field”) to which the management system according to the first embodiment is applied, and an arrangement of devices and the like. In the figure, reference numeral 500 indicates a chute (shoot field). The chute in the present embodiment is a place for sorting work that flows from upstream, for example, according to destination or purpose, for example, at a business site such as a logistics business. As shown in the figure, a plurality of workers can each perform work in the chute. In addition, a plurality of car cars are arranged on the chute. In addition, a large number of loads flow from the upstream (upper right in the figure) to the chute as needed. The car is equipped with wheels, and workers can load luggage into the car.

  In addition, the shoot field is provided with a plurality of RFID readers 501 and a plurality of antennas 502 so that the RFID tags in the shoot field can be read. RFID is an abbreviation for Radio Frequency Identifier. The RFID tag emits ID information for identifying each individual radio signal. The RFID reader 501 receives a radio signal from the RFID tag via the antenna 502 and reads ID information of each RFID tag. The RFID itself is realized by existing technology. In this embodiment, an RFID tag is provided on each of the worker's helmet, the car, and the luggage. Instead of the worker's helmet, an RFID tag may be provided on clothes or the like worn by the worker. Further, an RFID tag may be provided on a name tag worn by the worker. Therefore, individual workers, individual cars, and individual packages can be identified by ID information read by the RFID reader 501.

  A mat switch 503 is provided at an appropriate location in the chute. The mat switch 503 is, for example, a sheet-like object incorporating a pressure-sensitive switch. When the worker puts his / her weight on the mat switch 503, the mat switch 503 is switched between on (on) and off (off). In this embodiment, the mat switch 503 is turned on when the worker steps on the mat switch 503 and puts his weight, and the mat switch 503 is turned off when the worker leaves the mat switch 503. .

  That is, the mat switch 503 is a kind of human detection switch for detecting the weight of the worker. In the present embodiment, the mat switch 503 is used as the human detection switch, but other devices (for example, a device that detects visible light, infrared rays, or the like, or an image captured by a camera is analyzed to determine the presence of a worker. The presence of a person may be detected using a detection device or the like. With such a human detection switch, it can be grasped as information that the worker is in a specific place (or region) in the shooting field.

Moreover, the management apparatus 1 is provided in the chute or another room. The management device 1 has a function of performing wireless or wired communication with the RFID reader 501 and the mat switch 503. Thereby, the management apparatus 1 can receive the ID information read from the RFID by the RFID reader 501 and can receive information indicating the state (ON or OFF) of the mat switch 503.
The ID information of the RFID tag includes information indicating what it is for identifying. Thereby, based on the read RFID, the type of ID information (for example, distinction between luggage, a car, a worker, etc.) can be grasped.

  FIG. 2 is a schematic diagram showing a more detailed configuration and connection relationship of devices arranged in the chute shown in FIG. As shown in the figure, two RFID readers 501 are provided in the chute according to the present embodiment. These RFID readers are referred to as RFID readers 501-1 and 501-2. In addition, a plurality of antennas 502 and one mat switch 503 are connected to each of the RFID readers 501-1 and 501-2. Specifically, the RFID reader 501-1 is connected to the antenna 502-1-0, the antenna 502-1-1, and the mat switch 503-1. In addition, the RFID reader 501-2 is connected to the antenna 502-2-0, the antenna 502-2-1, and the mat switch 503-2. Each of the RFID readers 501-1 and 501-2 transmits information based on signals from the subordinate antenna 502 and subordinate mat switch 503 to the management apparatus 1. That is, each of the RFID readers 501-1 and 501-2 transmits the ID information read from the RFID and the on / off information of the mat switch 503 to the management apparatus 1.

The shoot field according to the present embodiment is provided with two RFID readers, four antennas, and two mat switches as shown here, but the number of each device is arbitrary. is there. The number of antennas 502 connected to one RFID reader 501 may be singular. A plurality of mat switches 503 may be connected to one RFID reader 501. Further, not all RFID readers 501 are necessarily connected to the mat switch 503.
That is, one RFID reader 501 is connected to one or more antennas 502 and zero or more mat switches 503 (human detection switches).

  The antenna 502 and the mat switch 503 are grouped in units, for example, for each shoot field or for each smaller area in the shoot field. For example, the four antennas 502-1-0, 502-1-1, 502-2-0, and 502-2-1 and the mat switches 503-1 and 503-2 shown in FIG. It is grouped as a shoot field device. The configuration information of the devices constituting the group is stored in the management apparatus 1. Moreover, the management apparatus 1 holds a rule for detecting a car, a luggage, and a worker. Rules are set as appropriate according to the environment of the shooting field.

  In the example shown in FIG. 2, the mat switch 503 is connected to the management apparatus 1 via the RFID reader 501, but even if the mat switch 503 is connected to the management apparatus 1 without going through the RFID reader 501. Good.

Next, the reading rule will be described. As an example, the rules in the apparatus configuration shown in FIG. 2 are as follows.
(1) Rules for car: (N ₁ time x antenna 502-1-0) OR (N ₂ times x antenna 502-1-1) OR (N ₃ times x antenna 502-2-0) OR (N ₄ Times x antenna 502-2-1)
In the description of this rule, “x” is an operator for representing the number of times of detection. “OR” is a logical operator representing a logical sum. In the rules relating to the car according to the above example, the same ID information for identifying the car is the antenna 502-1-0, the antenna 502-1-1, the antenna 502-2-0, or the antenna 502-2-1. , When a predetermined number of times (effective number of readings N ₁ , N ₂ , N ₃ , or N ₄ ) is detected within a predetermined time, the RFID having the ID information (that is, the car corresponding to the ID information is ) It is treated as correctly detected (passed) in the area of the group. Note that N ₁ , N ₂ , N ₃ , and N ₄ are integers of 1 or more, and are appropriately set for each antenna according to the environment of the shoot field.

(2) Luggage rules: (N ₁ time x antenna 502-1-0) OR (N ₂ times x antenna 502-1-1) OR (N ₃ times x antenna 502-2-0) OR (N ₄ times) × Antenna 502-2-1)
According to the rules regarding the luggage according to the above example, the same ID information for identifying the luggage is the antenna 502-1-0, the antenna 502-1-1, the antenna 502-2-0, or the antenna 502-2-1. When a predetermined number of times (effective number of readings N ₁ , N ₂ , N ₃ , or N ₄ ) is detected within a predetermined time, an RFID having the ID information (that is, a package corresponding to the ID information) corresponds to the group It is treated as what was correctly detected (pass) in the area of. N ₁ , N ₂ , N ₃ , and N ₄ are each an integer of 1 or more, and are the same as in the case of a car.

(3) Rules regarding workers (workers): ((N ₁ time × antenna 502-1-0) OR (N ₂ times × antenna 502-1-1) OR (N ₃ times × antenna 502-2- 0) OR (N ₄ times x antenna 502-2-1)) AND ((N ₅ times x mat switch 503-1) OR (N ₆ times x mat switch 503-2))
In the rule regarding the worker according to the above example, the same ID information for identifying the worker is the antenna 502-1-0, the antenna 502-1-1, the antenna 502-2-0, or the antenna 502-2-1. , A predetermined number of times (effective number of readings N ₁ , N ₂ , N ₃ , or N ₄ ) is detected within a predetermined time, and the mat switch 503-1 or the mat switch 503-2 is detected a predetermined number of times (effective When the number of reading times N ₅ or N ₆ ) is recognized as an ON state, the RFID having the ID information (that is, the worker corresponding to the ID information) is correctly detected in the area of the group ( It is treated as (pass). N ₁ , N ₂ , N ₃ , N ₄ , N ₅ , and N ₆ are each an integer of 1 or more as in the above case.

  In addition, regarding the above-mentioned worker rule, the determination based on the state of the mat switch can be omitted by parameter setting. When the determination based on the state of the mat switch is not performed, the worker is also determined based only on the number of times of reading the RFID information.

The car car rule, the luggage rule, and the worker rule are stored in advance in the leader group storage unit 55 in the form of conditional expressions. However, the value of the effective number of readings (N ₁ , N ₂ , N ₃ , N ₄ , N ₅ , N ₆ ) is stored in the determination parameter storage unit 54 as parameter information. That is, the number of effective readings can be made variable based on the setting.

That is, the condition stored in the leader group storage unit 55 is to enable the management object ID information (information for identifying the package), the distribution container ID information (information for identifying the car), or the worker ID information. This includes the condition of the effective reading number which is the number of readings within a predetermined time.
The condition stored in the leader group storage unit 55 may include a condition based on whether the mat switch is on or off as a condition for validating the worker ID information.
The conditions stored in the reader group storage unit 55 can be made variable depending on the combination of information for identifying the RFID reader and information for identifying the antenna.

The effective number of readings is the number of readings necessary for determining that the reading of the RFID tag information is “pass” in the above-described rule. In the mat switch determination, since the reading of RFID tag information about the worker is determined to be “pass” in the above-described rules, it is determined whether the mat switch is determined (determined) or not (not determined). It is information for.

  For example, when the RFID reader is “RFID reader 1” and the antenna is “antenna 0”, the RFID tag information holding period is “10” (seconds), and the effective reading count is “1” (times). The mat switch judgment is “judge”. When the RFID reader is “RFID reader 1” and the antenna is “antenna 1”, the RFID tag information holding period is “10” (seconds), and the effective reading count is “2” (times). The mat switch judgment is “judge”. The same applies to data in other rows.

Next, a processing procedure by the management apparatus 1 will be described.
FIG. 10 is a flowchart illustrating a processing procedure performed by the management apparatus 1. Hereinafter, it demonstrates along this flowchart. This flowchart shows processing related to RFID tag information read by one RFID reader.

First, in step S11, the RFID tag information reading unit 111 performs communication with the RFID reader 501-1 and requests the RFID tag information read by the RFID reader 501-1. In response to this, when there is read RFID tag information, the RFID reader 501-1 transmits the RFID tag information to the RFID tag information reading unit 111 side.
Next, in step S12, the mat switch pressure sensing unit 112 performs communication with the mat switch 503-1 and reads information indicating presence / absence of weighting in the mat switch 503-1.

  In step S13, the sensor information reading unit 11 checks whether there is read RFID tag information in response to the request for RFID tag information in step S11. If there is read RFID tag information (step S13: YES), the process proceeds to the next step S14. If there is no read RFID tag information (step S13: NO), the process returns to step S11.

When the process proceeds from step S13 to step S14, the processes of steps S14, S15, and S16 are sequentially performed as described below.
In step S14, the sensor information reading unit 11 includes information for identifying an RFID reader, a polling counter value, a time at that time, read RFID tag information, information for identifying a detection antenna, a mat switch On (ON, weighted) or off (OFF, unweighted) information indicating the presence or absence of weighting is registered in the RFID tag information storage unit 21.
In step S <b> 15, the sensor information reading unit 11 acquires information on the RFID effective holding period of the RFID reader to be processed from the determination parameter data table stored in the determination parameter storage unit 54. At this time, the sensor information reading unit 11 acquires information on the RFID effective holding period of the RFID reader to be processed. As described above, the RFID effective holding period is set for each antenna.

In step S <b> 16, the sensor information reading unit 11 deletes data that has passed the RFID effective holding period. Specifically, the sensor information reading unit 11 performs condition determination for each antenna regarding the RFID reader to be processed, and deletes data (record) that matches the deletion condition. The conditions are as the following conditions 1 and 2.
Condition 1: The RFID recorded in the record is the RFID reader to be processed. In addition, the antenna recorded in the record is “antenna 0”. In addition, the time recorded in the record is older (smaller as a date / time value) than (the time obtained by subtracting the RFID effective holding period related to “antenna 0” of the RFID from the current time).
Condition 2: The RFID recorded in the record is the RFID reader to be processed. The antenna recorded in the record is “antenna 1”. In addition, the time recorded in the record is older (smaller as a date / time value) than (the time obtained by subtracting the RFID effective holding period related to the “antenna 1” of the RFID from the current time).
Here, since there are two antennas “antenna 0” and “antenna 2” connected to one RFID reader, the above two conditions are used. If there are, for example, three or more antennas connected to one RFID reader, the deletion condition corresponding to each antenna is used in the same manner to delete records that meet the deletion condition.

Next, in steps S17 to S19, the management device 1 determines the tag type. Note that the tag type can be determined by, for example, appropriately designing a code system of RFID tag information.
In step S <b> 17, the worker person determining unit 31 determines whether or not the RFID tag information acquired this time is the tag information type of the worker person. If it is the tag information type of the worker in charge (step S17: YES), the process jumps to step S20. If it is not the tag information type of the worker in charge (step S17: NO), the process proceeds to the next step S18.
In step S18, the car car determination unit 32 determines whether or not the RFID tag information acquired this time is the car car tag information type. If it is the tag information type of the car (step S18: YES), the process jumps to step S20. If it is not the tag information type of the car (step S18: NO), the process proceeds to the next step S19.
In step S19, the package information determination unit 33 determines whether or not the RFID tag information acquired this time is the tag information type of the package. If it is the tag information type of the package (step S19: YES), the process proceeds to step S20. If it is not the tag information type of the package (step S19: NO), the process returns to step S11.
Note that the determination result in step S19 is “NO” when the tag information type is neither the person in charge of the work, the car nor the baggage, and it is considered that an error has occurred.

  Next, in step S <b> 20, the determination unit that matches the current tag type among the worker-in-charge determination unit 31, the car vehicle determination unit 32, and the luggage information determination unit 33 acquires group information from the reader group storage unit 55. To do. Specifically, any of the worker-in-charge determination unit 31, the car determination unit 32, and the luggage information determination unit 33 acquires a rule (conditional expression) for reading determination from the reader group storage unit 55. As described above, this rule (conditional expression) is set in advance for each worker, car, and luggage. In addition, any one of the worker-in-charge determination unit 31, the car vehicle determination unit 32, and the luggage information determination unit 33 acquires necessary parameter information from the determination parameter storage unit 54. The parameter information acquired here includes information on the number of effective readings set for each RFID reader and each antenna. When the above conditional expression includes a mat switch determination, the acquired parameter information includes information indicating whether or not to perform the mat switch determination (determining / not determining).

In step S21, the determination unit that matches the current tag type among the worker-in-charge determination unit 31, the car determination unit 32, and the package information determination unit 33 satisfies the acquired reading condition formula. It is determined whether it is (cleared) or not (matches the rule). If the conditional expression is satisfied (step S21: YES), the process proceeds to the next step S22. If the conditional expression is not satisfied (step S21: NO), the process returns to step S11.
When the reading condition includes a condition regarding the number of effective readings, the conditional expression may not be satisfied because the number of readings does not reach the number of effective readings for the current tag ID information. In this case, the conditional expression can be satisfied anew when the same tag ID information is read after the next time.

  In step S <b> 22, the control unit 39 determines the type of RFID tag information that is the current processing target, and performs processing distribution according to the type. If the RFID tag information is the type of the person in charge of the worker, the process proceeds to step S23. If the RFID tag information indicates the type of car, the process proceeds to step S24. If the RFID tag information is the type of package, the process proceeds to step S25.

Next, one of steps S23, S24, and S25 is executed according to the result of the distribution in step S24 above.
In step S <b> 23, the worker person determining unit 31 registers the RFID tag information in the worker person information storage unit 51.
In step S <b> 24, the car determination unit 32 registers the RFID tag information in the car information storage unit 52.
In step S <b> 25, the package information determination unit 33 registers the RFID tag information in the package information storage unit 53.

  When the process in step S23, S24, or S25 ends, the process returns to step S11 in order to acquire the next RFID tag information under the control of the control unit 39 of the management apparatus 1. Thereafter, for each RFID tag information, the management device 1 repeatedly executes the processing shown in this flowchart.

  FIG. 11 is a flowchart illustrating a procedure of the entire process performed by the management apparatus 1. As shown in the figure, after starting the process, the management apparatus 1 executes the process of step S101 and the process of step S102 in parallel.

  In step S <b> 101, the management apparatus 1 executes an RFID tag reading process by the RFID reader 1. In parallel with step S <b> 101, in step S <b> 102, the management apparatus 1 executes RFID tag reading processing by the RFID reader 2. Here, the RFID reader 501-1 in FIG. 3 corresponds to “RFID reader 1”. The RFID reader 501-2 corresponds to “RFID reader 2”. Each of the processing in step S101 and the processing in step S102 is the processing shown in FIG.

  In the present embodiment, the number of RFID readers is 2, and two processes of step S101 and step S102 are executed in parallel. Even when the number of RFID readers is other than 2, the management apparatus 1 causes the processing corresponding to each RFID to be executed in parallel.

Next, RFID tag information for each tag type will be described.
FIG. 12 is a schematic diagram illustrating an example of RFID tag information for each tag type. The figure shows, in order from the top, an example of tag information of an RFID tag of a worker, an example of tag information of an RFID tag of a car, and an example of tag information of an RFID tag of a luggage. In the example shown here, the tag information of the RFID tag of the worker in charge starts with “E” followed by an 8-digit decimal number. For example, the tag information is “E00000001”. The tag information of the car RFID tag begins with “B” and is followed by an 8-digit decimal number. For example, the tag information is “B00000001”. The tag information of the RFID tag of the package starts with “D” and is followed by an 8-digit decimal number. For example, the tag information is “D00000001”. As described above, the tag type can be distinguished by the code system of the tag information. In the present embodiment, the tag type can be determined by the type of the initial letter of the tag information. However, the tag type may be determined by other coding.

According to this embodiment, each RFID tag information read by the worker-in-charge determination unit 31, the car cart determination unit 32, and the baggage information determination unit 33 is passed based on the conditions stored in advance. It is determined whether or not. Thus, even if an RFID tag information reading error occurs, the influence of the error can be reduced. That is, it is possible to more accurately grasp the information on the worker, the car, and the luggage.
According to the present embodiment, the worker-in-charge determination unit 31, the car cart determination unit 32, and the baggage information determination unit 33 identify the worker-in-charge, the car, and the baggage, respectively. Thereby, it becomes possible to grasp the number of workers in charge at each time point, the number of car cars, and the number of luggage, respectively.
Further, according to the present embodiment, it is possible to collect identification information of a luggage, a car, and a worker in charge for each place (shooting field). As a result, it is possible to acquire information on the number of luggage, a car, and the number of workers in charge for each place at the time. By acquiring this number of information, you can control the amount (number) of baggage to flow for each location, control the number of car carts to be placed, and control the number of workers in charge. Basic data for doing this is obtained.

  Further, according to the present embodiment, it is possible to determine whether or not the tag ID information is acceptable based on the condition of the effective reading count. Thereby, the number of effective readings can be appropriately set as, for example, a system parameter, and the accuracy of tag ID information (for each baggage, cart, worker) can be raised.

  In addition, according to the present embodiment, it is possible to perform pass determination of the tag ID information of the worker in charge based on the human feeling information using the mat switch (human feeling detection switch).

  Further, according to the present embodiment, the management device acquires information from a plurality of places (shoot fields). Thereby, the tag ID information of the luggage, the car, and the worker can be acquired for each place.

  Further, according to the present embodiment, a parameter can be set for each combination of an RFID reader and an antenna. That is, the parameter for determining whether the ID information is acceptable can be made variable according to the location characteristics (RFID tag information reading characteristics, etc.).

(Second Embodiment)
Next, a second embodiment will be described. In addition, description may be abbreviate | omitted about the matter already demonstrated in previous embodiment. Here, the description will focus on matters specific to this embodiment.

FIG. 13 is a block diagram showing the configuration of the management system according to the present embodiment. As illustrated, the management system includes a plurality of management devices 1 and a database 600.
The management device 1 is a device as described in the first embodiment. The management device 1 receives and processes RFID tag ID information read by one or a plurality of chutes (locations). In addition, the management device 1 receives human information from a mat switch (human detection switch) provided on the chute. In FIG. 13, illustration of an RFID reader, an antenna, and a mat switch is omitted.

  The management device 1 is realized using, for example, a personal computer. A management device is provided for each physical distribution base. The distribution base is a collection / delivery base for collecting / delivering parcels, or a relay base for sorting parcels during the transit of parcels. The database 600 is realized using, for example, a server computer installed in a data center. The database 600 may be realized using a so-called cloud server. The database 600 collects data from the management device 1 at each site, and stores and accumulates the data. Specifically, the database 600 collects and stores information stored in the worker information storage unit 51, the car information storage unit 52, and the package information storage unit 53 in the management device 1. Further, the database 600 may collect data stored in the RFID tag information storage unit 21.

  Thus, by collecting and accumulating data not only from one location but from a plurality of locations, it becomes possible to analyze and utilize information from various aspects.

(Third embodiment)
Next, a third embodiment will be described. In addition, description may be abbreviate | omitted about the matter already demonstrated until previous embodiment. Here, the description will focus on matters specific to this embodiment.

FIG. 14 is a block diagram showing the configuration of the management system according to this embodiment. As shown in the figure, this management system includes a management device 1 and a sorter 700.
The management device 1 is a device as described in the first embodiment. The management apparatus 1 acquires and processes data from a plurality of shoots.
In FIG. 14, a thick line arrow heading from the outside toward the sorter 700 and a thick line arrow heading from the sorter 700 to the plurality of chutes represent the flow of the load. The sorter 700 has a function of distributing cargo flowing from the outside to a plurality of chutes based on control. When the load is sorted in the sorter 700, the load flows toward each chute.

  As described in the first embodiment, the management device 1 can identify the person in charge of the work, the car, and the luggage in each chute. Thereby, the management apparatus can grasp the number of workers in charge of each chute, the car, and the luggage. The management device 1 according to the present embodiment controls the sorting of packages by the sorter 700 based on the number of workers, carts, and packages. The control method is arbitrary.

  As an example, the management device 1 determines the number of workers, the number of car carts, and luggage in the most recent time zone (a time zone of a predetermined length (for example, 10 minutes, 30 minutes, 60 minutes)). The sorter 700 is controlled in accordance with the number of. Thereby, for example, the management device 1 performs control so as to allow a larger amount of subsequent packages to flow through a chute having a relatively large number of workers in relation to the number of packages. In addition, for example, the management device 1 performs control so as to allow a larger amount of subsequent packages to flow through a chute that has a relatively large number (or capacity) of car cars relative to the number of packages. Thus, in this embodiment, it is possible to grasp the situation of the chute numerically and perform control for distributing the cargo to be flowed to the chute based on the numerical value.

In each of the above embodiments, the processing corresponding to each RFID reader is executed in parallel (see FIG. 11), but the processing is not necessarily parallel processing. Processing corresponding to each RFID reader may be sequentially executed and repeated.
Further, in each of the above embodiments, the case where the management object is a luggage (luggage such as a courier) is described, but the management object may be other than the luggage. Also in this case, the RFID tag for reading the management object ID information for identifying the management object is attached to the management object.
In each of the above embodiments, the case where the physical distribution container is a car (having wheels, for example, a metal outer frame on which a management object can be placed or carried) is described. The logistics container may be a person other than the car. Even in this case, the physical distribution container is used for storing a management object. Further, the distribution container is attached with an RFID tag for reading distribution container ID information for identifying the distribution container.

  In each of the above embodiments, a pressure-sensitive mat switch is used as the human detection switch. As the human detection switch, other means can be used instead of the mat switch. For example, by using a device including a light emitting unit and a light receiving unit and detecting whether or not light emitted from the light emitting unit is blocked, human presence information (whether or not there is a person is expressed as on or off) Information) may be output. Further, for example, the presence information may be output by using a device that detects infrared rays so that the presence of a person can be detected. In addition, for example, the target area may be photographed with a camera, and the presence / absence of a person may be detected by analyzing the photographed image and the human information may be output.

According to at least one embodiment described above, each RFID tag read by the worker-in-charge determination unit 31, the car cart determination unit 32, and the baggage information determination unit 33 based on the conditions stored in advance. Determine whether the information is acceptable. Thus, even if an RFID tag information reading error occurs, the influence of the error can be reduced. That is, it is possible to more accurately grasp the information on the worker, the car, and the luggage.
In addition, according to at least one embodiment described above, the worker-in-charge determination unit 31, the car cart determination unit 32, and the baggage information determination unit 33 identify the worker-in-charge, the car, and the baggage, respectively. Thereby, it becomes possible to grasp the number of workers in charge at each time point, the number of car cars, and the number of luggage, respectively.
Further, according to at least one embodiment described above, it is possible to collect the identification information of the luggage, the car, and the worker in charge for each place (shooting field). As a result, it is possible to acquire information on the number of luggage, a car, and the number of workers in charge for each place at the time. By acquiring this number of information, you can control the amount (number) of baggage to flow for each location, control the number of car carts to be placed, and control the number of workers in charge. Basic data for doing this is obtained.

In that case, a program for realizing this function may be recorded on a computer-readable recording medium, and the program recorded on this recording medium may be read into a computer system and executed. Here, the “computer system” includes an OS and hardware such as peripheral devices. The “computer-readable recording medium” is a portable medium such as a flexible disk, a magneto-optical disk, a ROM, a CD-ROM, a DVD-ROM, a USB memory, or a storage device such as a hard disk built in a computer system. That means. Furthermore, a “computer-readable recording medium” dynamically holds a program for a short time, like a communication line when transmitting a program via a network such as the Internet or a communication line such as a telephone line. In this case, a volatile memory inside a computer system serving as a server or a client in that case may be included and a program held for a certain period of time. The program may be a program for realizing a part of the above-described functions, or may be a program that can realize the above-described functions in combination with a program already recorded in a computer system.
