Description

  The present invention combines an entry / exit machine that grasps a person's entry / exit, a storage that can grasp the entry / exit of a portable terminal, and a signal from a reader that grasps the presence of a portable terminal that has been delivered from the storage It is related with the positional information management system which can grasp | ascertain the state of a person and a portable terminal as accurately as possible.

  In recent years, the environment of free address offices where the seats used by employees are not fixed is increasing. In a room with a desk and chair, an employee carries a mobile phone or a portable terminal (notebook computer) and works at an empty desk, and all documents are personal or shared lockers, Characteristically, it is stored in a cabinet and does not have a specific personal work space.

  Since individuals do not have specific desks, personal belongings can be greatly reduced, and personal or shared lockers and cabinets are used to leave the company, so security is improved and electronic paper is used. This reduces the number of documents, improves the aesthetics of the office environment, and reduces the office area.

  However, since the work place of the employee is performed at an empty desk, the work place (sitting place) is different each time, and it is difficult to grasp where the employee is working. It is difficult to understand whether you are in the office or outside the company, or even what kind of situation is inside the company.

  In addition, since the mobile terminal is not fixed on the desk, it can be carried freely and taken outside the company without permission. For example, new security problems have occurred in portable terminals.

  In Patent Document 1, an electronic tag storing ID information is affixed to an asset such as a personal computer, and the ID of the electronic tag is associated with an asset management number, a manufacturing number, and the like and stored in an asset management database. In the case of regular take-out of assets such as personal computers, if the take-out person applies for take-out via a computer and the boss permits the take-out of assets such as personal computers, the asset management information in the asset management database is permitted to be taken out In addition, the asset take-out permission device installed at the entrance / exit window reads the ID stored in the electronic tag attached to the asset such as a personal computer and compares it with the stored take-out approval information. Asset take-out management system that checks for asset take-out and can be used to prevent take-out by making an alarm sound or turning on a lamp when illegal take-out It has been disclosed.

Japanese Patent No. 3952032

  However, although Patent Document 1 can prevent unauthorized take-out by the asset management information in the asset management database in the take-out permitted asset state, unauthorized use within the company (within free access), for example, a personal computer Unauthorized use such as use by a person who does not have the authority to use such information cannot be prevented.

  Further, in Japanese Patent Laid-Open No. 2004-133, although personal computer take-out management can be performed, the position of the personal computer user, that is, the employee, and the state thereof cannot be grasped.

  Furthermore, in order to grasp the position and state of the employee, for example, the personal computer user can carry an ID card with a built-in electronic tag and can always grasp the position, etc. There is a social situation to avoid as a legal issue in constantly monitoring the psychological burden of employees on location and personal behavior.

  Therefore, the present invention provides a signal from an entry / exit machine that grasps the entry / exit of a person, a storage that can grasp the entry / exit of the mobile terminal, and a reader that grasps the presence of the mobile terminal that has exited from the storage Provided is a positional information management system that can grasp the state of a person and a portable terminal with as high accuracy as possible only by combining them.

The portable terminal is provided in at least one area inside the area delimited by the entry / exit machine, and one or a plurality of storage boxes capable of confirming the entry / exit of the portable terminal with one reader in the storage space. One or a plurality of second readers capable of confirming whether or not they exist, and signals from the entry / exit machine, the first reader, and the second reader, and a person to be managed and a portable terminal Grasp the state of A location information management server that receives signals from the entry / exit machine, the first reader, and the second reader, and has a location information database that can be stored, The location information management server includes the latest entry signal or exit signal of the managed person from the entry / exit device stored in the location information database, and the latest entry signal of the mobile terminal from the first reader. Or a combination of the exit signal and the latest detection signal or non-detection signal of the mobile terminal from the second reader to grasp the status of the managed person and the mobile terminal, If there is a contradiction in the status of the managed person and the mobile terminal ascertained by the location information management server, the location information management server receives information from the entry / exit device. No. top priority, and then preferentially a signal from the first reader, and corrected to a consistent state inconsistent state knows, characterized in that it is a possible output to the outside.

  Further, the positional information management system according to the present invention corrects the detection signal or the non-detection signal from the second reader by forcibly changing to the other detection signal or the non-detection signal in the contradiction state. It is characterized by performing.

  Further, when the position information management server of the present invention receives a signal from any of the entry / exit machine, the first reader, or the second reader, the received signal is stored in the position information database. In addition, the latest signals from any two of the entry / exit machines other than the received signal, the first reader or the second reader are read from the position information database, and the three signals It is possible to perform combination and grasp the states of the managed person and the mobile terminal and output them to the outside.

  In addition, the location information management system according to the present invention is characterized in that an alarm can be issued according to the status of the managed person and the mobile terminal.

  Further, the entry / exit machine of the present invention can identify the managed person by reading the biological information of the managed person or information stored in an ID card held by the managed person. It is characterized by being.

  According to the positional information management system of the present invention, only by combining the signals from the entry / exit machine, the first reader provided in the storage, and the second reader installed in each part of the work space, It is possible to grasp the status of the person to be managed and the mobile terminal as accurately as possible.

  In addition, according to the present invention, it is easy to use an ordinary device such as an entrance / exit machine, a first reader provided in a storage, and a second reader installed in each part of a work space. With the configuration, it is possible to grasp the status of the person to be managed and the mobile terminal.

  In addition, according to the present invention, it is only possible to determine the combination of signals from the entry / exit machine, the first reader provided in the storage, and the second reader installed in each part of the work space, and to be managed. The status of the user and the mobile terminal can be grasped, and the status information can be used to detect unauthorized use of the mobile terminal and issue an alarm, or to synchronize with the schedule management software, etc. The status information can be used for various purposes.

  Moreover, according to this invention, the to-be-managed object obtained by combining the signal from the 2nd reader | leader installed in each location of the entrance / exit machine, the 1st leader with which the storage was equipped, and the work space If there is a contradiction in the state of the user and the portable terminal, the signal from the entry / exit machine is given the highest priority, the signal from the first reader is given the next priority, and the inconsistent state being grasped is consistent. In other words, the detection signal or non-detection signal from the second reader is forcibly changed to the other detection signal or non-detection signal and corrected, so that the managed object is as accurate as possible. It is possible to grasp the state of the person and the portable terminal.

  In addition, entry / exit management on entry / exit machines is usually performed consistently with normal attendance / exit management, which does not increase the psychological and work burdens of employees, and is provided in the storage. The first reader and the second reader installed in the work space automatically read the RFID tag built in or attached to the portable terminal without being conscious of the RFID tag. Since the target person can acquire the position information of the portable terminal without performing the reading operation of the RFID tag, the target person to be managed and the person to be managed without imposing a psychological burden or new work on the target person to be managed The state of the portable terminal can be grasped.

  In the area delimited by the entry / exit machine, the status of the person to be managed is grasped based on the status of the mobile terminal, and if the mobile terminal is detected in the work space, the location If the person to be managed is away from the site, the mobile terminal is expected to return to the location where it was detected. Therefore, it is not intended to manage the behavior and whereabouts of the person to be managed even in areas such as smoking rooms, canteens, and toilets.

[System configuration overview]
As shown in FIG. 1 to FIG. 3, a location information management system 1 according to the present invention includes a location information management server 10 that grasps the status of a managed person 3 and its mobile terminal 5 in this system, and a managed person. Entry / exit machine system 20 that can be passed only when 3 is specified, storage system 30 that can confirm entry / exit of portable terminal 5, and at least the inside of the area delimited by the entry / exit machine The work space system 40 that can confirm whether or not the mobile terminal 5 exists in one area is connected to the communication network 2, and the entry / exit machine system 20, the storage system 30, and the work space system 40 are The acquired position information can be transmitted to the position information management server 10.

  The communication network 2 is a computer network such as a LAN or an intranet. The communication network 2 may be either a wired or wireless environment, or a mixture of both, or any environment.

  The person to be managed 3 needs to identify himself / herself to the entry / exit machine system 20 by some method. For example, the user carries an ID card 4 for identifying himself / herself such as an employee number. Examples of the ID card 4 include a non-contact type IC card having a frequency band of 13.56 MHz. The reading distance between the ID card and the card reader is short, and the non-contact type IC card and the card reader are reliably brought into contact with each other to read the data in the card, so that high reading accuracy can be obtained.

  In addition, the person 3 to be managed does not carry the ID card 4, but enters and exits by biometric authentication using fingerprints, irises in the eyes, veins, voiceprints and / or facial shapes, etc. It may be possible to identify the person with respect to the machine system 20.

[About mobile terminals and their RFID tags]
The portable terminal 5 uses a notebook personal computer, a tablet terminal, or the like. In addition, the portable terminal 5 is attached with an RFID tag 6 which is a minute wireless IC chip used for identifying an object. Alternatively, it is natural that a function equivalent to the RFID tag 6 may be built in the portable terminal 5. The RFID tag 6 functions as a small transmitter attached to the portable terminal 5, and information transmitted from the RFID tag 6 includes “tag ID”, “mobile terminal ID”, and the like.

  Wireless tags such as RFID tags are roughly classified into active tags and passive tags depending on the format. An active tag is a tag that has a power source in its own casing and transmits radio waves by itself. Since the radio wave is transmitted by itself, it can be transmitted to the antenna even when the reader / writer is relatively separated and the distance is several tens to several hundreds of meters.

  A passive tag is a tag that, when receiving a radio wave emitted from an antenna, generates a radio wave by electrostatic induction of an antenna built in the passive tag and returns information to the antenna. Passive tags have a simple structure and can be mass-produced at low cost.

  Moreover, it can be easily attached to an article with a thickness of several millimeters. However, since they do not transmit themselves, the radio waves are weak, and the communication range between the passive tag and the antenna is limited to a few millimeters for short distances and to a few meters for long distances. For this reason, if a strong radio wave is transmitted, inconvenience occurs in the surrounding environment and equipment, so it is used in factories and hospitals.

  Thus, the active tag has an advantage that it can receive radio waves in a wide range. In addition, since passive tags receive radio waves in a narrow range, there is an advantage that measurement errors are less likely to occur during detection. On the other hand, antennas do not receive radio waves unless they are close enough to bring the tag into contact with the antenna. It can be said that it is suitable as a detection means in a limited space (narrow room) or when a detection space is intentionally limited.

  In the present invention, the mobile terminal 5 to which the RFID tag 6 is attached is moved by the managed person 3, and the position can be automatically detected without making the managed person 3 aware of the active tag and the passive tag. As for selection, it is desirable to select an appropriate method according to the size of the room in which the RFID tag 6 is desired to be detected and the situation in which it is desired to detect only in a part of the room.

  Communication between the RFID tag 6 and the reader antenna uses wireless communication. As general standards, it is preferable to use Wi-Fi (wireless fidelity: registered trademark) or IrDA (Infrared Data Association), but it is used for wireless communication between the reader antenna and the tag. If it does, there is no limitation.

  The current mainstream is equipment with outputs of 426 MHz, 950 MHz, and 2.45 GHz. When the output is 426 MHz, communication of about 20 m is possible, which is suitable for indoor position detection and entrance / exit management. Since 950 MHz and 2.45 GHz (IEEE802.155) are capable of longer distance communication, they are suitable for outdoor position detection.

[Location Management Server]
The location information management server 10 grasps the status of the managed person 3 and the portable terminal 5 and takes charge of the location information management system 1 of the present invention. The location information management server 10 includes a control unit 11, a display unit 12, and A position information database 13 is provided.

  The control unit 11 of the location information management server 10 communicates with the entry / exit machine system 20, the storage system 30, and the work space system 40, and writes (stores) / reads the received information to / from the location information database 13. At the same time, the read position information (various signal information) is combined to determine the state (state grasping) of the person 3 to be managed and the mobile terminal 5.

  In addition, the control unit 11 outputs various information held by the location information management server 10 and its determination result (understood state) to the display unit 12 so that the control unit 11 can visually recognize related persons such as managers, visitors, bosses, and colleagues. Can be notified.

Further, regarding the communication between the control unit 11 and the entry / exit machine system 20, the storage system 30, and the work space system 40, specifically, the entry / exit machine management server 21, the storage management server 31 and the work space provided therein. Reading information such as RFID or biometric information readers included in the management server 41 is received and stored in the position information database 13, and whether the gate can be opened or closed according to requests from the entry / exit machine management server 21 or the like Information that contributes to the determination is transmitted.
Further, the control unit 11 transmits information held by the location information management server 10 (information in the location information database 13) to the external server 50 in response to a request from the external server 50, or the location information management server 10 from the external server 50. It has a function to receive information and requests.

  The display unit 12 is a device that visually displays various types of information of the location information management server 10, and may be a liquid crystal display (LCD), a CRT (Cathode Ray Tube), or the like, and is not particularly limited.

  The position information database 13 stores information (various signals) transmitted from the entry / exit machine system 20, the storage system 30, and the work space system 40 in a predetermined database table, and records data according to instructions from the control unit 11. Delete, update, and read.

  The database 13 includes an entry / exit machine database 13a, a storage database 13b, and a work position database 13c corresponding to each of the entry / exit machine system 20, the storage system 30, and the work space system 40.

  As shown in FIG. 4, the contents of the tables of the entry / exit machine database 13a, the storage database 13b, and the work position database 13c are configured as follows as an example. For example, the entry / exit machine database 13a has an employee number field, an article ID field (portable terminal ID field), a read result field (entry / exit field) 13a1, and the like, and the read result transmitted from the entry / exit machine system 20 is displayed. Recorded in the reading result column (entry / exit column) 13a1.

  Further, the storage database 13b has, for example, a storage number field, an article ID field (portable terminal ID field), a reading result field (entry / exit field) 13b1, and the like, and reads the reading result of the storage system 30. Record in the result column (in / out column) 13b1.

  Further, the work position database 13c has an article ID column (portable terminal ID column), a reading result column (sitting state column) 13c1, and the like, and the reading result transmitted from the work space system 40 is displayed in the reading result column (sitting). Status column) 13c1.

[About entrance / exit systems]
The entry / exit machine system 20 includes an entry / exit machine management server 21, an entry / exit machine 22, an entry / exit reader 23, and an opening / closing door 24, and manages the entry / exit of the managed person 3 to and from the outside. To do.

  The entrance / exit machine management server 21 receives an entrance / exit detection signal (an entrance signal or an exit signal) from one or a plurality of entrance / exit readers 23, and the received signal is transmitted to the location information management server via the communication network 2. 10 has a function of transmitting to the network.

  The entrance / exit machine 22 functions as a gate including an opening / closing door 24, and serves as a work space 42 for the person 3 to be managed, for example, inside and outside the company, a room and the outside thereof. It plays a role of separating the area from the outside. It is intended to limit free entry / exit without specifying the entry / exit, and has the role of preventing intruders from entering.

  The managed person 3 reads the ID card for identification such as an employee number or his / her own biometric information by the entry / exit reader 23 connected to the entry / exit machine 22 and identifies the entry / exit person. Unless the door 24 is opened, the managed person 3 cannot pass through the entry / exit machine 22.

  The open / close door 24 is opened / closed under the control of the entry / exit machine 22 to physically limit the entry / exit of the person 3 to be managed, and the entry / exit of the flapper gate, slide door, revolving door, etc. can be specified. A configuration that does not require entry and exit is sufficient.

  The entry / exit reader 23 is an apparatus for reading and specifying the ID card 4 carried by the managed person 3 and the biological information of the managed person 3.

  For example, when the ID card 4 carried by the managed person 3 is a non-contact IC card, the entry / exit reader 23 uses a card reader in the 13.56 MHz frequency band. If the managed person 3 reads the ID card 4 but fails to read it, an error or the like is displayed on the spot, and the ID card 4 is again input / exited to the managed person 3. It is desirable to give an instruction via a display unit or the like provided in the entry / exit machine 22 so as to be read by the machine.

[About storage system]
The storage system 30 includes a storage management server 31, a storage 32, and a storage reader 33 that functions as a first reader, and is used for the mobile terminal 5 stored in the storage space in the storage 32. It is used to manage loading and unloading.

  The storage management server 31 receives an entry / exit detection signal (an entry signal or an exit signal) from one or a plurality of storage readers 33 installed inside one or a plurality of storages 32, and It has a function of transmitting the received signal to the location information management server 10 via the communication network 2.

  The storage 32 is a locker for storing the mobile terminal 5. Like a normal locker, it may be a form in which a plurality of portable terminals 5 are stored by providing a shelf inside, or a small locker in which the portable terminals 5 are stored one by one.

  The storage reader 33 is a device for reading the RFID tag 6 attached to or built in the portable terminal 5. The storage reader 33 arranges the necessary number corresponding to the reading performance inside the storage 32 at a position where the RFID tag 6 of the portable terminal 5 can be read.

  For example, the storage reader 33 is affixed to both inner walls of the storage 32, is attached to the inner ceiling of the storage 32, or the storage reader 33 is attached to the shelf inside the storage 32. It may be built in.

[Work space system]
The work space system 40 includes a work space management server 41 and a work space reader 43a and / or a work desk reader 43b that are arranged in the work space 42 and function as a second reader. 3 manages position information of the portable terminal 5 taken out from the storage 32 and carried.

  One or a plurality of work space readers 43a and work desk readers 43b functioning as the second reader are prepared, and the mobiles that have left the storage 32 in at least one area inside the area delimited by the entry / exit machine 22 are provided. Whether or not the terminal 5 exists is confirmed.

  The at least one area inside the area delimited by the entry / exit machine 22 is a case where the area inside the area delimited by the entry / exit machine 22 is large even if a plurality of second readers are arranged, However, it is difficult to detect and grasp the presence of the mobile terminal 5 in every place under circumstances such as complicated, so focus on desks and conference rooms where work is expected. A second reader is arranged.

  In addition, there is no need to place a second leader in passages, corridors, hot water rooms, smoking rooms, cafeterias, toilets, etc. where work is not expected, and personal information (individual behavior) is not required in those spaces. The second reader can be prevented from being installed so as not to be excessively specified.

  That is, in the present invention, after the entry / exit machine 22 identifies the managed person 3 to enter / exit, within the area delimited by the entry / exit machine 22, the managed person 3 is within the area. On the assumption that the mobile terminal 5 is in the state, the state of the managed person 3 and the mobile terminal 5 is estimated based on the state of the mobile terminal 5.

  When the mobile terminal 5 is detected in the area, it is assumed that the managed person 3 is in that place, and even if the managed person 3 is away from the place, Since the mobile terminal 5 is most likely to return to the detected location, it is assumed that the location is currently based.

  By doing so, it does not manage the behavior and whereabouts of the person to be managed 3 even in areas such as smoking rooms, canteens, and toilets, and prevents excessive identification of personal information (individual behavior) Thus, it is possible to prevent the occurrence of legal problems by constantly monitoring individual behavior without imposing a psychological burden on the subject to be managed.

  The work space management server 41 is installed in the area delimited by the entry / exit machine 22 and the RFID tag of the portable terminal 5 received by the work space reader 43a and the work desk reader 43b functioning as the second reader. 6 has a function of receiving a signal emitted by 6 and transmitting the received signal (detection signal or non-detection signal) to the location information management server 10 via the communication network 2.

  The work space 42 means a space in which work is predicted within an area delimited by the entry / exit machine 22, and the managed person 3 uses the portable terminal 5 such as installing a work desk 44. It is possible and possible place.

  When the work desk 44 is installed in the work space 42, the managed person 3 takes out the (designated) portable terminal 5 assigned to him / her from the storage 32 and puts it on the work desk 44. The portable terminal 5 is placed and used.

  The work desk 44 may be a commercially available office desk or the like, and is not particularly specified. However, the work desk reader 43b is installed and is built in or attached to the portable terminal 5 placed on the work desk 44. The RFID tag 6 can be read.

  In addition, the work space reader 43 a is arranged on the wall surface or ceiling of the work space 42 and is a device for reading the RFID tag 6 of the portable terminal 5 in the work space 42. Here, it is possible to install only the work desk reader 43b without installing the work space reader 43a, or conversely, it is possible to install only the work space reader 43a.

  In addition, when position information such as which second reader signal is added to the signal from the work space system 40, the position in the area of the management target person 3 and the portable terminal 5 is also specified. Is possible. That is, since it is considered that a plurality of work space readers 43a and / or work desk readers 43b functioning as second readers are used, the second reader here is specified, so that the person to be managed is identified. 3 and its position in the area of the portable terminal 5 can also be specified.

[Detection accuracy of each system]
The position information management system 1 according to the present invention performs correction and the like in consideration of differences in detection accuracy between the systems described so far, that is, the entry / exit machine system 20, the storage system 30, and the work space system 40. is there.

  That is, since the entry / exit machine 22 of the entry / exit machine system 20 can pass only when the managed person 3 can be identified, detection (entrance detection or exit detection) with extremely high accuracy (reliability) is possible. Is possible. Next, since the first reader (storage reader) of the storage system 30 is a limited space called a storage space in the storage 32, the detection is performed with high accuracy next to the detection of the entry / exit machine 22. (Incoming detection or leaving detection) is possible.

  Finally, for the second leader (work space leader 43a and / or work desk leader 43b) of the work space system 40, the area delimited by the entry / exit machine 22 after leaving the storage 32 Even in the interior, there are areas that can be detected by the second reader (work space) as described above, areas that cannot be detected or are not intended to be detected (such as hallways, smoking rooms, and toilets), and are originally storage Therefore, the detection accuracy is relatively lower than the other two systems.

  The position information management system 1 according to the present invention performs correction and the like in consideration of the difference in detection accuracy between these systems, and will explain RFID tag reading processing and reading result determination processing.

[Reading processing and determination processing of location information management system]

By applying the latest value in the reading result column (sitting state column) 13c1 of 13c to the table of FIG. 5, the state of the person to be managed 3 and the mobile terminal 5 is determined (understood).

For example, the latest reading results of a certain article ID (mobile terminal ID) in the reading result column (13a1, 13b1, 13c1) of each database (13a, 13b, 13c) are “entrance / exit, entry / exit, seating state: In the case of “011”, for example, the managed person 3 is in an area delimited by the entry / exit machine 22 such as in-house (left “0”), and the portable terminal 5 is taken out of the storage ( It can be understood that the middle side “1”) and the mobile terminal 5 are placed anywhere in the work space (left side “1”).

  As a result, the case corresponds to pattern 4 and, as shown in the status column of FIG. 5, it is determined (understood) that the mobile terminal is being used (sitting) in the area (for example, in-house). Is done.

  When position information such as which second reader signal is added to the signal from the work space system 40, the position in the area of the person to be managed 3 and the portable terminal 5 is specified. As described above, this is also possible.

[For example, "111"]
As another example, the latest reading results of other article IDs (portable terminal IDs) in the reading result column (13a1, 13b1, 13c1) of each database (13a, 13b, 13c) In the case of “exit, entry / exit, seating state: 111”, the managed person 3 is outside the area delimited by the entry / exit machine 22 such as outside (“1” on the left side), and the portable terminal 5 is stored. It can be grasped that it is taken out from the storage (middle side “1”) and that the portable terminal 5 is placed anywhere in the work space (left side “1”).

  As a result, the above case corresponds to pattern 8 and, as shown in the status column of FIG. 5, the mobile terminal 5 is being used in the office (sitting down) despite being outside the area (for example, outside the company). Therefore, the result is a judgment result (ascertainment result) suspected of being illegally used by another person or being taken out of the portable terminal 5 while leaving the storage 32.

  In that case, the latest reading result in the reading result column (13a1, 13b1, 13c1) of each database (13a, 13b, 13c) is read again to determine the latest reading result again, and again illegal use Check if the situation is suspected of forgetting.

  In addition, for example, the reading interval between the first reader and the second reader, which is usually 15 minutes, is narrowed to 3 minutes, etc., so that monitoring of the portable terminal 5 suspected of unauthorized use or forgetting is closely performed. To see if unauthorized use is still suspected.

  Furthermore, the past data of each database (13a, 13b, 13c) of the location information database 13 is read, and whether the portable terminal 5 has been issued while the managed person 3 is out of the area (outside the company) It is also possible to increase the accuracy of the unauthorized use determination by confirming whether the state has been reached.

  And in re-reading or judging, even after passing through various confirmation work such as confirmation of transition in past data, when it is concluded that there is a high degree of judgment that it is forgotten or unauthorized use Displays alarms (warnings) on the display unit 12 and issues alarms. Furthermore, an alarm can be output to the outside through the external server 50.

[For example, “001”]
As yet another example, the latest reading results of some other article ID (mobile terminal ID) in the reading result column (13a1, 13b1, 13c1) of each database (13a, 13b, 13c). In the case of “entry / exit, entry / exit, seated state: 001”, the managed person 3 is in an area delimited by the entry / exit machine 22 such as in-house (“0”), the mobile terminal 5 Is stored in the storage (“0”), and that the portable terminal 5 is placed anywhere in the work space (“1”).

  As a result, the above case corresponds to Pattern 2, and as shown in the status column of FIG. 5, the mobile terminal 5 is stored in the storage in the area (for example, in-house), but the mobile terminal 5 is used. Thus, it is determined that the state is not possible (inconsistent state), and the “abnormal” determination shown in FIG. 5 is made.

  In that case, the latest reading result in the reading result column (13a1, 13b1, 13c1) of each database (13a, 13b, 13c) is read again to determine the latest reading result again, and again, a contradiction state. Check if it is.

  Further, for example, the reading interval between the first reader and the second reader, which is normally 15 minutes, is narrowed to 3 minutes, etc., and the mobile terminal 5 in a contradictory state is closely monitored, and the contradiction Check if it is in a state.

  If the contradiction state is not resolved even in the re-reading and determination, the signal from the work space system 40 with the lowest detection accuracy is changed from “sitting (1)” to “no sitting (0)”. Forcibly correct to eliminate inconsistency.

  As described above, this depends on the reliability of the reading accuracy of the entry / exit reader 23, the first reader, and the second reader, and includes the entry / exit machine system 20, the storage system 30, and the work space system 40. Since the detection accuracy (reliability) is high in order, the control unit 11 sets the “entrance / exit”, “entry / exit”, “seating state” for “entry / exit, entry / exit seating state, seating state” of the reading result. In order of priority, if the results of “entry / exit” and “sitting state” are inconsistent, the result of “entry / exit” is positive, the result of “sitting state” is incorrect, and “sitting state” is It is forcibly corrected to resolve the contradiction state.

[About judgment processing order]
In describing a detailed flowchart of the determination process, an outline of the order of the determination process will be described as shown in FIG.

  For the location information management system 1 of the present invention, in order to determine (understand) the status of the managed person 3 and the mobile terminal 5 in an orderly manner, the inventor detects, for example, as shown in FIG. Processing is performed by determining from a system with low accuracy (reliability) to a system with high accuracy, and when the system with the highest accuracy is reached, the determination shifts to the determination with the system with the lowest accuracy and the determination with 3 systems is performed. The flow to be performed is given as an example.

  In FIG. 6, if the system that detected the signal at the time of determination or most recently is a work space, for example, as shown in the upper row, next, the determination in the storage with the second highest detection accuracy is performed, and finally, Judgment is performed by an entry / exit machine with high detection accuracy, and the state of the managed person 3 and the mobile terminal 5 is determined (understood) in an orderly manner.

  In addition, the system which detected the signal at the time of determination is determined from the system of the received signal (the signal received at that time) when the location information management server 10 performs determination when receiving a signal from each system. The state of the person to be managed 3 and the mobile terminal 5 is determined (obtained) in advance, and the determination result of the state is stored in a determination result database (not shown) in the position information database 13. In other words, it means that the latest state is appropriately read out from a determination result database (not shown) or the like and output according to the request of the user and administrator of this system, the external server 50, and the like.

  That is, when the location information management server 10 receives a signal from any of the entry / exit machine system 20, the storage system 30, or the work space system 40, the location information management server 10 stores the received signal in the location information database 10 and receives it. The latest (most recent) signal of another system (the remaining two systems) other than the system of the signal is read from the position information database 10 and a combination of the three signals is performed. The state of the machine 5 is grasped.

  In addition, the most recently detected signal system is the system that has received the most recent signal in the case where determination is made at an appropriate timing in response to a request from the user or administrator of the system, the external server 50, or the like. From this signal, it means that the determination work is started each time.

  Similarly, in the middle part of FIG. 6, if the system that detected the signal at the time of determination or most recently is a storage, then the determination at the entry / exit machine with the highest detection accuracy is performed, and finally the detection accuracy is determined. And the state of the managed person 3 and the portable terminal 5 are determined in an orderly manner (understood).

  Similarly, in the lower part of FIG. 6, if the system that detected the signal at or near the determination time is an entry / exit machine, the determination is next performed in the work space with the lowest detection accuracy, and finally the detection accuracy is Is determined by the storage that has not been determined yet, and the state of the management target person 3 and the mobile terminal 5 is determined in order (ascertained).

  The flow described below is created as an example of the determination process based on this order, and is not limited to this determination order.

  For example, when the determination is made from the system with the low detection accuracy (reliability) shown in FIG. 6 to the system with the highest accuracy, and the system with the highest accuracy is reached, the determination shifts to the determination with the system with the lowest accuracy. Contrary to the flow to be performed, processing is performed by determining from a system with high detection accuracy (reliability) to a system with low accuracy, and when reaching the system with the lowest accuracy, the determination is made with the system with the highest accuracy. It may be a flow that shifts to and performs determination in three systems.

[Details of flowchart of judgment processing]
The details of the flowchart of the determination process of the location information management system according to the present invention will be described with reference to FIGS.

  As shown in FIG. 7, when starting the determination process (S1), first, the system that has received the signal at or near the determination time is first determined (S2 to S4).

  For example, when a signal is detected at or near the determination time in the entry / exit machine system, the answer is Yes in step 2 (S2), and according to the lower order of FIG. 6, as shown in FIG. 8, "entrance / exit" (S10) The determination is made in the order of “sitting state” (S11, S15) → “entrance / exit” (S12, S14, S16, S18).

  8 to 10, three-digit numbers such as “1__”, “1_1”, “100” described in the vicinity of each step are “entrance / exit (0: in area, 1: "Outside area)" is shown on the left, "In / Out (0: inside, 1: outside)" is shown on the inside, and "Sitting (0: not seated, 1: seated)" The numbers on the right are shown. Further, “_ (under bar)” such as “1__” indicates that the determination process has not been performed yet.

  Specifically, in FIG. 8, if the managed person 3 in step 10 (S10) is outside the entry / exit machine 22 (Yes: 1__), the process proceeds to step 11 (S11), and the work space If there is no portable terminal in 42 (No: 1 — 0), the process proceeds to step 14, and if the portable terminal 5 is stored in the storage 32 (Yes: 100), the pattern 5 shown in FIG. 5 is obtained. This pattern 5 is a state in which the managed person 3 and the portable terminal 5 are in a state where the managed person 3 is out of the area and the portable terminal 5 is stored in the storage 32. As a result, it is possible to output the determined state to the display unit 12 or the external server 50.

  In FIG. 8, if the management target person 3 in step 10 (S10) is inside the entry / exit machine 22 (No: 0__), the process proceeds to step 15 (S15), and the portable terminal is placed in the work space 42. If there is (Yes: 0_1), the process proceeds to Step 16, and if the portable terminal 5 is stored in the storage 32 (Yes: 001), the pattern 2 shown in FIG. 5 is obtained.

  In this pattern 2, the managed person 3 and the mobile terminal 5 are in a state where the managed person 3 is in the area and the portable terminal 5 is stored in the storage 32. Inconsistently, it is determined that the user is sitting (the mobile terminal 5 is detected in the work space), and the determination result is inconsistent (inconsistent state). And / or re-detection in the storage system 30 and the work space system 40).

  If the inconsistent state continues even after this rescan, the read result “001” is corrected to “000” (S17), and the state is more accurately grasped. Thereby, it is possible to output the determined state with high accuracy to the display unit 12 or the external server 50.

  In FIG. 8, if the management target person 3 in step 10 (S10) is outside the entry / exit machine 22 (Yes: 1__), the process proceeds to step 11 (S11), and the portable terminal is placed in the work space 42. If there is 5 (Yes: 1_1), the process proceeds to Step 12 (S12), and if the mobile terminal 5 has left the storage 32 (No: 111), the pattern 8 shown in FIG. 5 is obtained.

  This pattern 8 is that the managed person 3 and the portable terminal 5 are in a state where the portable terminal 5 is working (sitting) even though the managed person 3 is outside the area, Re-scanning (reading from the location information database again and / or re-detection in the storage system 30 and the work space system 40) because of the possibility of unauthorized use of the portable terminal 5 or the possibility of forgetting it. After that, if the state continues (if it remains in the “111” state), alarm display / alarm is performed.

  The above description is the same in FIG. 9 and FIG. 10, and in FIG. 7, when the system that received the signal at or near the determination time is a storage system, the steps in FIG. 3 (S3), the process proceeds to step 20 (S20) in FIG. 9, and thereafter, “entry / exit” (S20) → “entrance / exit” (S21, S26) → “sitting state” (S22, S24, The determination is made in the order of S27, S29), and the state consisting of the eight patterns shown in FIG. 5 is determined (obtained), and output to the display unit 12 or the external server 50 becomes possible.

  In this case, when there is a contradiction in the determination result (contradiction) as in the case where the seating determination is made in step 22 (S22) (Yes: 101) and the case in which the seating determination is made in step 24 (S24) (Yes: 001). If the inconsistent state continues even after rescanning, the reading result is corrected (S23, S25), and the state is more accurately grasped.

  In addition, when the seated determination is made in step 27 (S27) (Yes: 111), the portable terminal 5 is working (sitting) even though the managed person 3 is out of the area. Since it is suspected that the portable terminal 5 may be illegally used or forgotten, the alarm is displayed and issued after the necessary confirmation work (S28).

  If the system that has received the signal at or near the determination time in FIG. 7 is a work space system, it follows Yes in step 4 (S4) of FIG. 7 according to the upper order of FIG. 6, and step 40 (S40) of FIG. Then, determination is made in the order of “sitting state” (S40) → “entrance / exit” (S41, S47) → “entrance / exit” (S42, S45, S48, S49), and the eight patterns shown in FIG. To grasp the state consisting of

  In this case, when the entry / exit determination is made in step 42 (S42), in any case (101,001), the portable terminal 5 is stored in the storage, but the work space 42, the determination result is inconsistent (contradictory state), so the “abnormal” determination shown in FIG. 5 is made. If the inconsistency state continues even after rescanning, the reading result Correction is performed (S43, S44), and a more accurate state is grasped.

  In addition, when the out-of-region determination is made in step 45 (S45) (Yes: 111), the portable terminal 5 is working (sitting) even though the person to be managed 3 is outside the region. Since it is suspected that the portable terminal 5 may be illegally used or forgotten, the alarm is displayed and issued after the necessary confirmation work (S46).

  The present invention can be embodied in many forms without departing from its essential characteristics. Therefore, it is needless to say that the above-described embodiment is exclusively for description and does not limit the present invention.
