Description

  The present invention relates to a boarding / alighting detection program, a boarding / alighting detection method, and a boarding / alighting detection system for detecting an elevator boarding / alighting of an object.

  For example, elevator boarding / alighting detection that detects the elevator boarding / exiting of objects (persons, objects, etc.) includes elevator operation control according to the number of passengers, guidance of people waiting for the elevator, marketing based on the traffic flow of shoppers in high-rise buildings, It is used to improve operational efficiency based on the flow of employees in the building office.

  For example, the following technology can be used for elevator boarding / alighting detection. A technique for detecting an entrance / exit of a person using an electronic tag is conventionally known (see, for example, Patent Document 1).

  The technology for detecting the entrance / exit of a person using an electronic tag is to attach an electronic tag to a person, provide a shield that attenuates the signal of the electronic tag at the entrance / exit boundary, and install a reader near the exit or entrance to detect the signal of the electronic tag. Receive. For example, when the reader is installed near the exit, the signal intensity from the electronic tag possessed by the person entering the room increases gently until the person passes through the entrance / exit shield, but rapidly decreases after the passage. On the other hand, the signal intensity from the electronic tag held by the person who exits gradually increases at a low level until passing through the shield, but rapidly increases after passing. The signal intensity from the electronic tag possessed by a person who has just passed near the exit without entering the room rises gently when the person approaches the reader, and gently declines when he moves away.

  The technology that detects the entrance / exit of a person using an electronic tag makes use of the difference in the magnitude of the change in signal intensity from the electronic tag, and whether the person entered the room, left the room, or just passed nearby. To identify.

  In addition, a technique for installing an electronic tag and a reader in various places and identifying the position of a person or an object from fluctuations in signal intensity from the electronic tag is conventionally known (for example, Patent Document 2).

  If there is nothing between the electronic tag and the reader, the signal intensity from the electronic tag is stable. When a person or an object enters between the electronic tag and the reader, the signal intensity from the electronic tag becomes unstable during that time. A technology that installs electronic tags and readers at various locations and identifies the position of a person or an object from fluctuations in the signal intensity from the electronic tag detects such a change in the signal intensity from the electronic tag to detect the person or object. Specify the position of.

  In addition, a technique for photographing a front of an elevator with a camera and identifying movement of a person or an object from a change in an image is conventionally known.

  However, in the conventional technique for detecting the entrance / exit of a person using an electronic tag, accurate identification cannot be performed if the movement speed of the person changes. If a person approaches the reader quickly, the signal intensity from the electronic tag that the person has increases rapidly. If the person approaches the reader slowly, the increase in signal strength from the electronic tag that the person has becomes moderate.

  Similarly, when a person moves away from the reader quickly, the signal strength from the electronic tag held by the person rapidly decreases. If the person moves away from the reader lately, the signal strength from the electronic tag held by the person will be moderate.

  In this way, in the conventional technology that detects the entrance / exit of a person using an electronic tag, it is determined whether the difference in signal intensity from the electronic tag is due to the passage of the shield or the movement speed of the person. Because it was not possible, it was not possible to correctly identify whether a person entered the room, left the room, or just passed near a place where people would come and go at various speeds such as in stores.

  In addition, with conventional technology that installs electronic tags and readers at various locations and identifies the position of people and objects from fluctuations in the signal intensity from the electronic tag, the position can be accurately identified when multiple people or objects move. Can not do.

  For example, when there is already a person or thing between a certain electronic tag and a reader, even if another person or thing passes through the signal, the signal intensity is already unstable, and the passage cannot be detected. In places where many people gather, such as stores, the location of people and things could not be specified.

  With the conventional technology that uses a camera to identify the movement of people and objects from changes in the image, the objects are hidden and overlapped in places where many people and objects gather. Could not be accurately identified.

  An object of one embodiment of the present invention is to provide a boarding / alighting detection program, a boarding / alighting detection method, and a boarding / alighting detection system that can accurately detect an elevator boarding / alighting of an object.

  In order to solve the above-described problem, an embodiment of the present invention is directed to a computer, from a receiving unit that receives a signal from a transmitting unit attached to an elevator and a target to get on and off the elevator, from the receiving unit to the transmitting unit. A data collection step for collecting data relating to a signal from a signal, and a reception start time difference and a reception end of a signal from the transmission means attached to the elevator and a signal from the transmission means attached to the object from the data A time difference is obtained. If the reception start time difference is less than or equal to a first threshold, it is determined that the vehicle is getting off from the target elevator, and if the reception end time difference is less than or equal to a second threshold, the target elevator is A boarding / alighting detection step for determining boarding is executed.

The boarding / alighting detection system according to the present embodiment can accurately identify whether an elevator boarding / exiting, that is, entering or exiting an elevator car or just passing through the vicinity, even if a large number of people or objects move in various ways. Thus, the problem that the identification accuracy is affected by the moving speed, number, and arrangement of the objects is solved.

  FIG. 1 is a configuration diagram of an embodiment of a boarding / alighting detection system according to this embodiment. The boarding / alighting detection system 1 includes a boarding / alighting detection device 10, readers 11-1 to 11-m, electronic tags 12-1 to 12-n, an electronic tag 13, and a network 15.

  The electronic tags 12-1 to 12-n are attached to a person or an object that is a target for detecting getting on and off the elevator 14. The electronic tag 13 is attached in the elevator 14. When any of the electronic tags 12-1 to 12-n may be used, it is simply referred to as an electronic tag 12. The electronic tags 12 and 13 repeatedly transmit unique identification information (ID) by radio waves. Note that a plurality of electronic tags 12 or 13 may be attached to a target person or object, or the elevator 14.

  By attaching a plurality of electronic tags 12 or 13 to the target person or object or the elevator 14, the boarding / alighting detection system 1 of this embodiment increases the reception frequency of the readers 11-1 to 11-m and fails in reception. It is possible to alleviate the problem, to prevent the detection of the target due to the failure of the electronic tag 12 or 13 or the battery exhaustion, or to detect the failure of the electronic tag 12 or 13.

  The leaders 11-1 to 11-m are installed in each elevator hall. When any of the readers 11-1 to 11-m is acceptable, it is simply referred to as a reader 11. The reader 11 is connected to the boarding / alighting detection device 10 via the network 15 so that data communication is possible. The network 15 may be wireless communication or wired communication, and may be a LAN or the Internet.

  The boarding / alighting detection apparatus 10 includes a target / location information management unit 16, an elevator boarding / alighting determination unit 17, and a data collection unit 18. The target / location information management unit 16 holds a location management table and manages the location where the reader 11 is installed and the identification information of the reader 11 in association with each other. The target / location information management unit 16 holds a target management table, and manages target identification information, identification information of the electronic tag 12 or 13, and target type in association with each other. The elevator boarding / alighting determining unit 17 determines boarding / alighting of the target person or thing to / from the elevator 14. The data collection unit 18 collects detection data from the reader 11. Details of the target / location information management unit 16, the elevator boarding / alighting determination unit 17, and the data collection unit 18 will be described later.

  The boarding / alighting detection apparatus 10 is realized by a computer 20 such as a server computer or a client computer. The computer 20 in which the boarding / alighting detection program is installed is an example of the boarding / alighting detection apparatus 10.

  FIG. 2 is a hardware configuration diagram of an example of a boarding / alighting detection apparatus. Here, the hardware configuration of the computer 20 in which the boarding / alighting detection program is installed will be described. The computer 20 executes a boarding / alighting detection program having the same function as the boarding / alighting detection apparatus 10.

  A computer 20 in FIG. 2 includes an input device 21, a display device 22, and a computer main body 23. The computer main body 23 includes a main storage device 31, an arithmetic processing device 32, an interface device 33, a recording medium reading device 34, and an auxiliary storage device 35 that are connected to each other via a bus 37. The input device 21 and the display device 22 are connected to the bus 37.

  The input device 21, the display device 22, the main storage device 31, the arithmetic processing device 32, the interface device 33, the recording medium reading device 34, and the auxiliary storage device 35 that are mutually connected by the bus 37 are managed by the arithmetic processing device 32. Can exchange data with each other. The arithmetic processing unit 32 is a central processing unit that controls operation of the entire computer 20.

  The interface device 33 receives data from the network 15 or the like, and passes the contents of the data to the arithmetic processing device 32. The interface device 33 transmits data to the network 15 or the like in response to an instruction from the arithmetic processing device 32.

  The auxiliary storage device 35 stores a boarding / alighting detection program that causes the computer 20 to execute at least processing in the boarding / alighting detection device 10 as part of a program that causes the computer 20 to perform the same function as the boarding / alighting detection device 10.

  Then, the arithmetic processing unit 32 reads out and executes the boarding / alighting detection program from the auxiliary storage device 35, so that the computer 20 functions as the boarding / alighting detection device 10. The boarding / alighting detection program may be stored in the main storage device 31 accessible to the arithmetic processing device 32.

  The input device 21 receives data input under the control of the arithmetic processing device 32. The boarding / alighting detection program can be recorded on a recording medium 36 readable by the computer 20.

  Examples of the recording medium 36 include a magnetic recording medium, an optical disk, a magneto-optical recording medium, and a semiconductor memory. Magnetic recording media include HDDs, flexible disks (FD), magnetic tapes (MT) and the like. Examples of the optical disc include a DVD (Digital Versatile Disc), a DVD-RAM, a CD-ROM (Compact Disc-Read Only Memory), and a CD-R (Recordable) / RW (ReWriteable). Magneto-optical recording media include MO (Magneto-Optical disk).

  When distributing the boarding / alighting detection program, for example, it is conceivable to sell a portable recording medium 36 such as a DVD or a CD-ROM in which the boarding / alighting detection program is recorded. The computer 20 that executes the boarding / alighting detection program reads the boarding / alighting detection program from, for example, the recording medium 36 on which the recording medium reader 34 has recorded the boarding / alighting detection program. The arithmetic processing device 32 stores the read boarding / alighting detection program in the main storage device 31 or the auxiliary storage device 35. The computer 20 reads the boarding / alighting detection program from the main storage device 31 or the auxiliary storage device 35, which is its own storage device, and executes processing according to the boarding / alighting detection program.

  FIG. 3 is a flowchart illustrating an example of the operation of the reader. The reader 11 proceeds to step S1 and determines whether or not a signal is received from the electronic tag 12 or 13. The reader 11 repeats the process of step S1 until a signal is received from the electronic tag 12 or 13. When the signal is received from the electronic tag 12 or 13, the reader 11 proceeds to step S2, and acquires the signal from the electronic tag 12 or 13 as tag transmission data. In step S <b> 3, the reader 11 generates detection data from the acquired tag transmission data, and notifies the data collection unit 18 of the boarding / alighting detection device 10 of the detection data.

  FIG. 4 is a configuration diagram of an example of detection data. The detection data has time or elapsed time, reader ID, electronic tag ID, and reception intensity. The time or elapsed time represents the time when the signal from the electronic tag 12 or 13 is received or the elapsed time since the reader 11 is activated. The reader ID is identification information unique to the reader 11. The electronic tag ID is unique identification information of the electronic tag 12 or 13. The reception intensity is the reception intensity of the signal from the electronic tag 12 or 13.

  FIG. 5 is a configuration diagram of another example of detection data. FIG. 5 shows detection data when the reader 11 has a plurality of antennas. The detection data in FIG. 5 includes time or elapsed time, reader ID, electronic tag ID, reception intensity for each channel 1 to n corresponding to an antenna, and a transmission counter value. When the electronic tag 12 or 13 transmits information other than the electronic tag ID, information other than the electronic tag ID may be added to the detection data as additional information. The transmission counter value is an example of additional information.

  The transmission counter value is a value of a counter that counts the number of transmissions that the electronic tag 12 or 13 has inside. For example, assuming that the received transmission counter value is c2 and the previously received transmission counter value is c1, the boarding / alight detection device 10 has no reception failure if c2-c1 is 1, and c2-c1-1 times if c2-c1> 1. It can be determined that there has been a reception failure.

  FIG. 6 is a flowchart illustrating an example of the operation of the data collection unit. The data collection unit 18 proceeds to step S11, and determines whether or not there is a notification of detection data from the reader 11. Until the detection data is notified, the data collection unit 18 repeats the process of step S11. When receiving the detection data, the data collection unit 18 proceeds to step S12, and generates and records the reception data from the notified detection data.

  FIG. 7 is a configuration diagram of an example of received data. The reception data has a reception data ID, time, reception intensity, tag ID, and reader ID. The reception data ID is unique identification information of the reception data. The time is the time when the reader 11 receives a signal from the electronic tag 12 or 13. The reception intensity is the reception intensity of the signal received by the reader 11 from the electronic tag 12 or 13. The tag ID is unique identification information of the electronic tag 12 or 13 from which the reader 11 has received a signal. The reader ID is identification information unique to the reader 11 that has received a signal from the electronic tag 12 or 13.

  As shown in FIG. 5, when the received data is detection data including a plurality of received intensities, the maximum value may be the received intensity, the average value may be the received intensity, and the median is the received intensity. It is good.

  FIG. 8 is a flowchart of another example showing the operation of the reader. In step S21, the reader 11 initializes the detection data log and empties it. In step S22, the reader 11 determines whether or not a signal is received from the electronic tag 12 or 13. The reader 11 repeats the process of step S22 until a signal is received from the electronic tag 12 or 13. When the signal is received from the electronic tag 12 or 13, the reader 11 proceeds to step S23 and acquires the signal from the electronic tag 12 or 13 as tag transmission data. In step S24, the reader 11 generates detection data from the acquired tag transmission data and adds it to the detection data log.

  In step S25, the reader 11 determines whether there is a data request from the data collection unit 18 of the boarding / alighting detection device 10. If there is no data request from the data collection unit 18, the reader 11 returns to step S22. If there is a data request from the data collection unit 18, the reader 11 proceeds to step S 26, transmits the detection data log to the data collection unit 18 of the boarding / alighting detection device 10, returns to step S 21, and again detects the data in step S 21. The operation is repeated from the initialization of the data log. The detection data log includes an arbitrary number of detection data.

  FIG. 9 is a flowchart of another example showing the operation of the data collection unit. The data collection unit 18 proceeds to step S31 and substitutes 1 for i. In step S 32, the data collection unit 18 determines whether i is larger than the number of readers 11. If it is determined that i is not larger than the number of readers 11, the data collection unit 18 transmits a data request to the reader 11-i.

  In step S34, the data collection unit 18 receives the detection data log from the reader 11-i. In step S35, the data collection unit 18 generates and records received data from each of the detected data constituting the received detected data log. In step S36, the data collection unit 18 adds 1 to i, returns to step S32, and repeats the operation from step S32. If it is determined in step S32 that i is larger than the number of readers 11, the data collection unit 18 proceeds to step S37, waits for time t, and then repeats the operation from step S31.

  The operation of the data collection unit 18 shown in FIG. 9 transmits a data request to each of the readers 11-1 to 11-m, receives a detection data log, and receives data from each of the detection data constituting the detection data log. Is generated and recorded.

  FIG. 10 is a flowchart illustrating an example of the operation of the elevator boarding / alighting determination unit. In step S41, the elevator boarding / alighting determination unit 17 reads the received data recorded by the data collection unit 18. In step S42, the elevator boarding / alighting determination unit 17 generates continuous reception data for each electronic tag 12 or 13 and reader 11 from the reception data. In step S43, the elevator boarding / alighting determination unit 17 determines the target boarding / alighting from the continuous reception data, and registers the result in the boarding / alighting data. The operation of the flowchart shown in FIG. 10 may be executed periodically, for example, once a day, or may be executed when new received data is recorded in the data collection unit 18.

  FIG. 11 is a configuration diagram of an example of continuous reception data. Continuous reception data refers to a series of reception data groups in which a certain reader 11 continues to receive a signal from a certain electronic tag 12 or 13 at a time interval of ΔT or less. ΔT may be, for example, the transmission interval of the electronic tag 12 or 13, or twice the transmission interval, or a set value.

  The continuous reception data shown in FIG. 11 has a continuous reception data ID, a start point reception data ID, an end point reception data ID, a tag ID, a reader ID, and a location ID. The continuous reception data ID is unique identification information of the continuous reception data. The starting point received data ID is the received data ID of the first received data in time series among the target received data. The end point reception data ID is the reception data ID of the last reception data in time series among the target reception data.

  The tag ID is unique identification information of the electronic tag 12 or 13 from which the reader 11 has received a signal. The reader ID is identification information unique to the reader 11 that has received a signal from the electronic tag 12 or 13. The place ID is identification information unique to the place where the reader 11 is installed. The location ID is acquired from the target / location information management unit 16. In step S42 of FIG. 10, the elevator boarding / alighting determination unit 17 inquires of the target / location information management unit 16 and acquires the location ID.

  The object / location information management unit 16 holds a location management table and returns a location ID corresponding to the reader ID in response to an inquiry from the elevator boarding / alighting determination unit 17. FIG. 12 is a configuration diagram of an example of the location management table. The location management table has a location ID and one or more reader IDs. The place ID is identification information unique to the place where the reader 11 is installed. One or more reader IDs are the reader IDs of the readers 11 installed at the location indicated by the location ID. That is, a plurality of readers 11 may be installed at the place indicated by the place ID. In that case, the location ID is associated with a plurality of reader IDs.

  The elevator boarding / alighting determining unit 17 determines boarding / alighting of the target elevator 14 corresponding to each electronic tag 12 or 13 from the continuous reception data. Here, a description will be given of a method of discriminating whether to get on and off the target elevator 14 corresponding to each electronic tag 12 or 13 from the continuous reception data.

  FIG. 13 is an explanatory diagram of an example of a method for determining whether the user gets on or leaves the elevator. FIG. 13 shows an example in which the target X with the electronic tag X gets on the elevator Y with the electronic tag Y, and the target Z with the electronic tag Z leaves (leaves) from the elevator hall where the reader R is installed. Represents.

  FIG. 13A is a schematic diagram showing an example of the relationship between an object X with an electronic tag X, an object Z with an electronic tag Z, an elevator Y with an electronic tag Y, and an elevator hall in which a reader R is installed. FIG. FIG. 13B is a graph illustrating an example of the reception intensity of signals received by the reader R from the electronic tags X, Y, and Z.

  The reader R receives the transmission of the electronic tags X, Y and Z. FIG. 13B represents a part of the end of the continuous reception data corresponding to each of the electronic tags X, Y, and Z. In FIG. 13B, the vertical axis represents reception intensity and the horizontal axis represents time. The elevator boarding / alighting determination unit 17 determines the difference de between the time when the signal reception from the electronic tag Y attached to the elevator Y stops and the time when the reception signal from the electronic tags X and Z attached to the objects X and Z stops. Ask for each.

  The reception signal from the electronic tag X attached to the target X that gets on the elevator Y is interrupted almost simultaneously with the reception signal from the electronic tag Y attached to the elevator Y at the timing when the door of the elevator Y is closed and moved. It becomes impossible to receive. This is because the doors of the elevator Y and the floor (in the ceiling) block radio waves transmitted from the electronic tags X and Y.

  On the other hand, the reception signal from the electronic tag Z attached to the target Z that does not get on the elevator Y is independent of the reception signal from the electronic tag Y attached to the elevator Y, at any timing when the target Z leaves the elevator hall. It stops and becomes unreceivable.

  Therefore, the elevator boarding / alighting determination unit 17 determines the difference between the time when the signal reception from the electronic tag Y attached to the elevator Y is interrupted and the time when the reception signals from the electronic tags X and Z attached to the objects X and Z are interrupted. If | de | is equal to or less than the threshold Te, it is determined as “boarding (temporary)”, and if it exceeds the threshold Te, it is determined as “leaving”. Therefore, in the example of FIG. 13, it can be determined that the target X to which the electronic tag X is attached is “riding (provisional)” and the target Z to which the electronic tag Z is attached is “leaving”.

  However, if the target Z to which the electronic tag Z is attached accidentally leaves the elevator hall at the timing when the door of the elevator Y is closed and moved, the time when the signal reception from the electronic tag Y attached to the elevator Y is interrupted, and the target The difference | de | from the time when the received signal from the electronic tag Z attached to Z is interrupted may be equal to or less than the threshold Te as shown in FIG.

  FIG. 14 is an explanatory diagram of another example of a method for determining whether an elevator is getting on or off. FIG. 14 shows that the target X with the electronic tag X gets on the elevator Y with the electronic tag Y, and the target Z with the electronic tag Z moves from the elevator hall where the reader R is installed with the door of the elevator Y closed. Represents an example of leaving (withdrawn) at the same timing.

  FIG. 14A is a schematic diagram showing an example of the relationship between an object X with an electronic tag X, an object Z with an electronic tag Z, an elevator Y with an electronic tag Y, and an elevator hall in which a reader R is installed. FIG. FIG. 14B is a graph illustrating an example of the reception intensity of signals received by the reader R from the electronic tags X, Y, and Z.

  Since FIG. 14 is the same as FIG. 13 except for a part thereof, description thereof will be omitted as appropriate. The reader R is installed near the entrance of the elevator Y. Therefore, since the reception intensity of the signal received from the electronic tag X attached to the target X boarded on the elevator Y becomes unreceivable at the timing when the door of the elevator Y is closed and moved, it is high even immediately before the reception becomes impossible. .

  On the other hand, the reception intensity of the signal received from the electronic tag Z attached to the target Z away from the elevator hall is low just before the reception becomes impossible because it is already away from the elevator hall by a receivable distance.

  Therefore, the elevator boarding / alighting determination unit 17 determines the difference between the time when the signal reception from the electronic tag Y attached to the elevator Y is interrupted and the time when the reception signals from the electronic tags X and Z attached to the objects X and Z are interrupted. When | de | is equal to or less than the threshold Te and it is determined that “ride (temporary)”, the following determination is further performed.

  The elevator boarding / alighting determination unit 17 receives signals X from the tags X and Z attached to the target X and Z at the time te0 immediately before the signal reception from the electronic tag Y attached to the elevator Y is interrupted. Find re_z. The elevator boarding / alighting determination unit 17 determines “ride” if the reception strengths re_x and re_z of the signals received from the electronic tags X and Z attached to the objects X and Z are equal to or greater than the threshold value Re, and if smaller than the threshold value Re, Judgment is made.

  The elevator boarding / alighting determination unit 17 may set dte seconds before the signal reception from the electronic tag Y attached to the elevator Y as the time point te0, smoothes the reception intensity of the signal received from the electronic tag Y in time series, The inclination of the received intensity change at each time point is obtained from n reception intensities before and after that time point, and the time point when the inclination first becomes θe or less in time series may be set as te0, and the received intensity of the signal received from the electronic tag Y is Smoothing is performed in time series, and the variance vt of the received intensity in the range of dt seconds before and after each time is obtained, and the last time when the variance vt of the received intensity exceeds the threshold Ve from the preset threshold Ve may be set as te0. . The smoothing may be obtained by applying a polynomial model or an additive regression model, for example. The slope may be obtained by applying the least square method or the like.

  FIG. 15 is an explanatory diagram of an example of a method for determining getting off or approaching from an elevator. In FIG. 15, the target X with the electronic tag X gets off (gets off) from the elevator Y with the electronic tag Y, and the target Z with the electronic tag Z enters the elevator hall where the reader R is installed (approached). ) Represents an example.

  FIG. 15A is a schematic diagram showing an example of a relationship between an object X with an electronic tag X, an object Z with an electronic tag Z, an elevator Y with an electronic tag Y, and an elevator hall in which a reader R is installed. FIG. FIG. 15B is a graph illustrating an example of the reception intensity of signals received by the reader R from the electronic tags X, Y, and Z.

  The reader R receives the transmission of the electronic tags X, Y and Z. FIG. 15B represents a part of the head of continuous reception data corresponding to each of the electronic tags X, Y, and Z. In FIG. 15B, the vertical axis represents reception intensity and the horizontal axis represents time. The elevator boarding / alighting determination unit 17 determines the difference ds between the time when the signal from the electronic tag Y attached to the elevator Y starts to be received and the time when the signals from the electronic tags X and Z attached to the objects X and Z start to be received. For each.

  The reception signal from the electronic tag X attached to the target X that gets off from the elevator Y is received almost simultaneously with the reception signal from the electronic tag Y attached to the elevator Y when the elevator Y stops and the door opens. start. On the other hand, the reception signal from the electronic tag Z attached to the target Z approaching the elevator hall is independent of the reception signal from the electronic tag Y attached to the elevator Y, and at any time when the target Z approaches the elevator hall. Start receiving.

  Therefore, the elevator boarding / alighting determination unit 17 starts receiving a signal from the electronic tag Y attached to the elevator Y, and starts receiving signals from the electronic tags X and Z attached to the objects X and Z. If the difference | ds | Accordingly, in the example of FIG. 15, it is possible to determine that the target X to which the electronic tag X is attached is “getting off (provisional)” and the target Z to which the electronic tag Z is attached is “approaching”.

  However, when the target Z to which the electronic tag Z is attached accidentally approaches the elevator hall at the timing when the elevator Y stops and the door opens, the reception time from the electronic tag Y attached to the elevator Y starts to be received. The difference | ds | between the electronic tag Z attached to the target Z and the time when the reception signal starts to be received may be equal to or less than the threshold Ts as shown in FIG.

  FIG. 16 is an explanatory diagram of another example of a method of determining getting off or approaching an elevator. FIG. 16 shows that the target X with the electronic tag X gets off from the elevator Y with the electronic tag Y, the target Z with the electronic tag Z stops in the elevator hall where the reader R is installed, and the elevator Y stops and the door Represents an example of entering (approaching) at the opening timing.

  FIG. 16A is a schematic diagram showing an example of the relationship between an object X with an electronic tag X, an object Z with an electronic tag Z, an elevator Y with an electronic tag Y, and an elevator hall in which a reader R is installed. FIG. FIG. 16B is a graph showing an example of the received intensity of signals received by the reader R from the electronic tags X, Y, and Z.

  Since FIG. 16 is the same as FIG. 15 except for a part thereof, the description thereof will be omitted as appropriate. The reader R is installed near the entrance of the elevator Y. Therefore, the reception intensity of the signal received from the electronic tag X attached to the target X that gets off from the elevator Y is high when the elevator Y stops and the door opens, and is high immediately after reception is possible. On the other hand, since the reception intensity of the signal received from the electronic tag Z attached to the target Z approaching the elevator hall starts to be received from a receivable distance, it is low immediately after reception is possible.

  Therefore, the elevator boarding / alighting determination unit 17 determines the difference between the time when signal reception from the electronic tag Y attached to the elevator Y starts and the time when signal reception from the electronic tags X and Z attached to the objects X and Z starts. When | ds | is equal to or less than the threshold value Ts and is determined to be “get off (temporary)”, the following determination is further performed.

  The elevator boarding / alighting determination unit 17 receives signals rs_x received from signals X and Z attached to the target X and Z at time ts0 immediately after the signal reception from the electronic tag Y attached to the elevator Y starts. Find rs_z. The elevator boarding / alighting determination unit 17 determines “get off” if the reception strengths rs_x, rs_z of the signals received from the electronic tags X, Z attached to the objects X, Z are equal to or greater than the threshold Rs, and “ It is determined as “approaching”.

  The elevator boarding / alighting determination unit 17 may set dts seconds after the start of signal reception from the electronic tag Y attached to the elevator Y as the time point ts0, smoothing the reception intensity of the signal received from the electronic tag Y in time series, The inclination of the received intensity change at each time point is obtained from n reception intensities before and after the relevant time point, and the time point when the inclination first becomes θe or less in time series may be set as ts0. Smoothing in time series, the reception intensity variance vt in the range of dt seconds before and after each time may be obtained, and the time when the reception intensity variance vt is less than or equal to a preset threshold value Vs may be set as te0.

  The operation of the elevator boarding / alighting determination unit 17 that determines the target boarding / alighting from the continuous reception data shown in Step S43 of FIG. 10 and registers the result in the boarding / alighting data is performed, for example, according to the procedure shown in FIG.

  FIG. 17 is a flowchart illustrating an example of the operation of step S43 of the elevator boarding / alighting determination unit. The operation shown in FIG. 17 is executed for each newly generated continuous reception data. In step S51, the elevator boarding / alighting determination unit 17 sets the continuous reception data as cx and the electronic tag corresponding to the continuous reception data cx as the electronic tag x. In step S52, the elevator boarding / alighting determination unit 17 acquires the tag IDs of one or more electronic tags y attached to the elevator Y from the target / location information management unit 16. The elevator boarding / alighting determination unit 17 extracts each piece of continuous reception data cy corresponding to the acquired tag ID of the electronic tag y.

  Proceeding to step S53, the elevator boarding / alighting determination unit 17 obtains start time xs, ys of the continuous reception data cx, cy from the reception data of FIG. The elevator boarding / alighting determination unit 17 obtains a time difference ds with respect to the start point time xs of the continuous reception data cx and the start point time ys of the continuous reception data cy from the following equation (1).

    ds = | xs−ys | (1)

  In step S54, the elevator boarding / alighting determination unit 17 obtains end points xe and ye of the continuous reception data cx and cy from the reception data of FIG. The elevator boarding / alighting determination unit 17 obtains a time difference de for the end point time xe of the continuous reception data cx and the end point time ye of the continuous reception data cy from the following equation (2).

    de = | xe-ye | (2)

  In step S55, the elevator boarding / alighting determination unit 17 determines whether or not the obtained time difference ds is equal to or less than a threshold value Ts. If the time difference ds is equal to or smaller than the threshold value Ts, the elevator boarding / alighting determination unit 17 proceeds to step S56, obtains cy 'obtained by smoothing the continuous reception data cy, and obtains time ts0 at which the slope of cy' is equal to or smaller than θs. In step S57, similarly to the continuous reception data cy, the elevator boarding / alighting determination unit 17 obtains cx 'obtained by smoothing the continuous reception data cx, and obtains the reception intensity rs at time ts0.

  In step S58, the elevator boarding / alighting determination unit 17 determines whether or not the obtained reception intensity rs is equal to or greater than a threshold value Rs. If the reception intensity rs is equal to or greater than the threshold value Rs, the elevator boarding / alighting determination unit 17 proceeds to step S59, and determines that the starting point action of the target x attached with the electronic tag x is “get off”.

  On the other hand, when the time difference ds exceeds the threshold value Ts in step S55, or when the reception intensity rs is smaller than the threshold value Rs in step S58, the process proceeds to step S60, where the elevator boarding / alighting determination unit 17 starts the target x with the electronic tag x attached. The action is determined as “approaching”.

  Progressing to step S61 following step S59 or S60, the elevator boarding / alighting determination unit 17 determines whether or not the obtained time difference de is equal to or less than a threshold value Te. If the time difference de is equal to or less than the threshold value Te, the elevator boarding / alighting determination unit 17 proceeds to step S62, obtains cy ′ obtained by smoothing the continuous reception data cy, and obtains time te0 at which the slope of cy ′ is equal to or less than θe. In step S63, the elevator boarding / alighting determination unit 17 obtains cx ′ obtained by smoothing the continuous reception data cx, similarly to the continuous reception data cy, and obtains the reception intensity re at time te0.

  In step S64, the elevator boarding / alighting determination unit 17 determines whether or not the obtained reception intensity re is equal to or greater than a threshold value Re. If the reception intensity re is greater than or equal to the threshold value Re, the elevator boarding / alighting determination unit 17 proceeds to step S65, and determines that the end point action of the target x attached with the electronic tag x is “ride”.

  On the other hand, when the time difference de exceeds the threshold Te in step S61, or when the reception intensity re is smaller than the threshold Re in step S64, the process proceeds to step S66, where the elevator boarding / alighting determination unit 17 ends the target x with the electronic tag x attached. The action is determined as “withdrawal”. Proceeding to step S67 following step S65 or S66, the elevator boarding / alighting determination unit 17 adds the starting point action and the ending point action of the target x with the electronic tag x to the getting on / off data.

  FIG. 18 is a configuration diagram of an example of the target management table. The object management table is held by the object / location information management unit 16, for example. The target management table has a target ID, one or more tag IDs, and a type. The target ID is identification information unique to the target type. The tag ID is unique identification information of the electronic tag 12 or 13 associated with the target type. The type is information indicating what the object is. The target / location information management unit 16 can return a tag ID corresponding to the designated type by using the target management table of FIG.

  FIG. 19 is a configuration diagram of an example of getting-on / off data. The boarding / alighting data is information representing an elevator boarding / alighting determination result. The boarding / alighting data has a boarding / alighting data ID, a target ID, a continuous reception data ID, and a determination. The boarding / alighting data ID is unique identification information of boarding / alighting data. The target ID is identification information unique to the target type. The continuous reception data ID is unique identification information of the continuous reception data. The determination is information obtained by connecting the start point action and the end point action.

  For example, the meaning of the record of boarding / exiting data ID = 1 shown in FIG. 19 is that the stroller (target ID = 1) with the electronic tag 12 of tag ID = 310010... 310110 is 10:00 on January 8, 2010. This indicates that the vehicle was approaching the place of place ID = 1 at 0 minute and got on the elevator at 10: 10: 0 on the same day.

  In addition, 10:00:00 on January 8, 2010 is obtained from the continuous reception data ID = 1 and the start point reception data ID = 1. 10: 10: 0 on the same day is obtained from continuous reception data ID = 1 and end point reception data ID = 50.

  FIG. 20 is a flowchart illustrating an example of operations for obtaining threshold values Ts, Rs, Te, and Re. The operation of the flowchart shown in FIG. 20 may be executed, for example, by the elevator boarding / alighting determination unit 17 before the start of the determination execution, may be executed periodically, or may be executed according to a user instruction. Note that the operation of the flowchart shown in FIG. 20 is executed for each of the electronic tags 12.

  In step S71, the elevator boarding / alighting determination unit 17 collects past continuous reception data for the electronic tag x attached to each target x. Proceeding to step S72, the elevator boarding / alighting determination unit 17 determines, for each continuous reception data xd, the continuous reception data yds of the electronic tag y having the closest start point among the electronic tags y attached to the elevator y, and the electronic tag y having the closest end point. The continuous reception data yde is obtained.

  In step S73, the elevator boarding / alighting determination unit 17 obtains a start time difference ds and an end point time difference de for the continuous reception data yds and the continuous reception data yde corresponding to each continuous reception data xd.

  In step S74, the elevator boarding / alighting determination unit 17 sets ts0 immediately after the start of the continuous reception data yds and te0 immediately before the end of the continuous reception data yde for the continuous reception data yds and the continuous reception data yde corresponding to each continuous reception data xd. The reception strengths rs and re of the electronic tag x at each of ts0 and te0 are obtained.

  The elevator boarding / alighting determination unit 17 may set dts seconds after the start of the continuous reception data yds as ts0, smooth the reception intensity of the continuous reception data yds in a time series, and set the gradient of the reception intensity change at each point in time. The time when the slope first falls below θs in the time series may be obtained as ts0, and the reception intensity of the continuous reception data yds is smoothed in the time series, and the range of dt seconds before and after each time. The reception time variance vt may be obtained, and the first time point when the reception strength variance vt falls below a preset threshold value Vs may be set as ts0.

  The elevator boarding / alighting determination unit 17 may set dte seconds before the end of the continuous reception data yde as te0, smooth the reception intensity of the continuous reception data yde in time series, and change the gradient of the reception intensity change at each time point before and after the time point It may be determined from n received intensities, and the time when the slope first becomes θe or less in time series may be set as te0, and the received intensity of the continuous reception data yde is smoothed in time series, and reception in the range of dt seconds before and after each time The strength dispersion vt is obtained, and the last time point when the reception strength dispersion vt exceeds the threshold Ve from a preset threshold Ve may be set as te0. Smoothing may be obtained by applying, for example, a polynomial model or an additive regression model. The slope may be obtained by applying the least square method or the like.

  In step S75, the elevator boarding / alighting determination unit 17 obtains threshold values Ts, Rs, Te, and Re for all the continuous reception data xd. The elevator boarding / alighting determination unit 17 classifies pairs of the starting point time difference ds and the reception intensity rs, and sets the boundaries as thresholds Ts and Rs. Similarly, the elevator boarding / alighting determination unit 17 classifies pairs of the end point time difference de and the reception strength re, and sets the boundaries as Te and Re. For the classification, for example, a cluster analysis method may be used. The boundary may be obtained by, for example, a linear discrimination method.

  FIG. 21 is a graph illustrating an example of the relationship between the pair classification and the threshold values Ts, Rs, Te, and Re. FIG. 21A is a graph in which the horizontal axis represents the start time difference ds and the vertical axis represents the reception level rs. FIG. 21A is a graph plotting pairs (ds, rs) of the starting point time difference ds and the reception intensity rs for all continuous reception data xd.

  The pair (ds, rs) of the starting point time difference ds and the reception strength rs in FIG. 21A can be classified into three groups A, B, and C by the cluster analysis method. Group A has a short start point time difference ds and a high reception strength rs, and corresponds to a case of getting off. Group B corresponds to the case where the starting point time difference ds is short but the reception strength rs is low, and accidentally approaches the elevator hall when the elevator y arrives. Group C corresponds to a case where the start point time difference ds is long and is irrelevant to the elevator y. The two straight lines Rs and Ts are determined by obtaining the boundaries of the groups A, B, and C by a linear discriminant method. The two straight lines Rs and Ts serve as threshold values.

  FIG. 21B shows a graph of the end point time difference de on the horizontal axis and the reception level re on the vertical axis. FIG. 21B is a graph plotting pairs (de, re) of the end point time difference de and the reception strength re for all continuous reception data xd.

  The pair (de, re) of the end point time difference de and the reception strength re in FIG. 21B can be classified into three groups A, B, and C by the cluster analysis method. Group A has a short end point time difference de and a high reception strength re, which corresponds to the case of boarding.

  Group B corresponds to the case where the end point time difference de is short but the reception strength re is low, and when the elevator y moves, the elevator y moves away from the elevator hall. Group C corresponds to a case where the end point time difference de is long and is irrelevant to the elevator y. The two straight lines Re and Te serving as threshold values are determined by determining the boundaries of the groups A, B, and C by a linear discriminant method.

  1 includes the object / location information management unit 16, the elevator boarding / alighting determination unit 17, and the data collection unit 18, but may be distributed to a plurality of server devices.

  FIG. 22 is a configuration diagram of another embodiment of the boarding / alighting detection system of this embodiment. The boarding / alighting detection system 2 includes readers 11-j to 11-i, electronic tags 12-1 to 12-n, an electronic tag 13, a network 15, a boarding / alighting detection device 40, and a terminal 43. The boarding / alighting detection system 2 in FIG. 22 is a service in which a store clerk or a staff member informs the user of the crowded state of the elevator 14 in the elevator hall, or controls the boarding / alighting of the customer to avoid congestion, and customer satisfaction Elevator waiting time counting for surveys, etc. corresponds to this. 22 is the same as the boarding / alighting detection system 1 shown in FIG. 1 except for a part thereof, and a description thereof will be omitted as appropriate.

  The elevator boarding / alighting determination unit 17 performs the operation shown in FIG. 17 at the timing when newly received data is recorded by the data collection unit 18. As a result of the execution, the elevator boarding / alighting determination unit 17 sends newly registered boarding / alighting data as shown in FIG. 23 to the elevator waiting / boarding counter unit 41, for example.

  FIG. 23 is a configuration diagram of another example of the getting-on / off data. The boarding / alighting data has a boarding / alighting data ID, a target ID, an elevator ID, a place ID, a continuous reception data ID, a determination (start), and a determination (end). The boarding / alighting data ID is unique identification information of boarding / alighting data. The target ID is identification information unique to the target type.

  The elevator ID is identification information unique to the elevator 14. The place ID is identification information unique to the place where the reader 11 is installed. The continuous reception data ID is unique identification information of the continuous reception data. The determination (start) is information on the start point action. The determination (end) is information on the end point action.

  In step S67 of FIG. 17, the elevator boarding / alighting determination unit 17 registers the start point behavior in the determination (start) of the boarding / alighting data and registers the end point behavior in the determination (end). The elevator boarding / alighting determination unit 17 does not know whether or not the end point is received when the continuous reception data is continued, that is, when the next signal is received without ΔT from the reception of the previous signal from the electronic tag 12 or 13 by the reader 11. Therefore, in that case, “undecided” is assumed.

  Further, when the determination (start) of the boarding / alighting data is “get off” or the determination (end) is “boarding”, the elevator boarding / alighting determination unit 17 obtains the tag ID of the electronic tag 13 attached to the elevator 14 from the target management table. The elevator ID corresponding to the tag ID is registered in the getting on / off data. Otherwise, the elevator boarding / alighting determination unit 17 registers “undecided” in the elevator ID of the boarding / alighting data.

  After receiving the boarding / alighting data, the elevator waiting / boarding counter unit 41 updates the boarding number data, the waiting data, and the waiting time data for each boarding / alighting data. FIG. 24 is a block diagram of an example of boarding number data. The boarding number data holds the number of boarding for each elevator ID. The elevator ID is unique identification information of an object whose type of the object management table is an elevator. The number of rides is the number of rides for each elevator ID. The initial value of the number of rides is zero.

  FIG. 25 is a configuration diagram of an example of waiting data. For each location ID, the waiting data holds a waiting data and a boarding data ID list of the corresponding boarding data. This is unique identification information of the place where the reader 11 is installed. The waiting number is the number of users waiting for the elevator 14 at the place corresponding to the place ID. The boarding / alighting data ID list is a boarding / alighting data ID list of boarding / alighting data corresponding to a customer waiting for the elevator 14 at a place corresponding to the place ID. FIG. 26 is a configuration diagram of an example of the waiting time data. The waiting time data holds the correspondence between the waiting time and the getting-on / off data ID.

  FIG. 27 is a flowchart illustrating an example of the operation of the elevator waiting / ride counter unit. The elevator waiting / ride counter unit 41 proceeds to step S81 and starts the operation for the boarding / alighting data a. In step S82, the elevator waiting / ride counter 41 determines whether the determination (start) of the getting-on / off data a is “get off” or “approach”.

  If the determination (start) of the boarding / alighting data “a” is “get off”, the elevator waiting / boarding counter unit 41 proceeds to step S83 and decreases the boarding number of the boarding number data corresponding to the elevator ID of the boarding / alighting data by one. On the other hand, if the determination (start) of the boarding / alighting data a is “approaching”, the elevator waiting / boarding counter unit 41 proceeds to step S84, and the determination (end) of the boarding / alighting data a is “undecided”, “riding” or “leaving” "Is determined.

  If the determination (end) of the boarding / alighting data a is “undecided”, the elevator waiting / boarding counter unit 41 proceeds to step S85, and searches the elevator hall management table described later for a place ID corresponding to the elevator ID of the boarding / alighting data a. Ask.

  FIG. 28 is a configuration diagram of an example of an elevator hall management table. The elevator hall management table holds an elevator ID and a terminal address for each location ID. The elevator hall management table has a location ID, one or more elevator IDs, and a terminal address. The elevator waiting / boarding counter unit 41 increases the waiting data waiting number corresponding to the searched place ID by 1 and adds the boarding / alighting data ID of the boarding / alighting data a to the boarding data ID list.

  If the determination (end) of the boarding / alighting data a is “boarding”, the elevator waiting / boarding counter unit 41 proceeds to step S86 and increments the boarding number of the boarding number data corresponding to the elevator ID of the boarding / alighting data by one.

  Progressing to step S87 following step S86, the elevator waiting / ride counter unit 41 obtains the corresponding continuous reception data ID from the getting-on / off data, obtains the start point reception data ID from the corresponding continuous reception data, and receives the reception time from the corresponding reception data. Ask for. This reception time is the time tw when the object starts waiting.

  Similarly, the elevator waiting / ride counter unit 41 obtains the end point reception data ID from the corresponding continuous reception data, and obtains the reception time from the corresponding reception data. This reception time is the time tr when the target boarded. Using the time tr-tw as a waiting time, the elevator waiting / ride counter unit 41 sends it to the elevator waiting time recording unit 42 together with the boarding / alighting data ID. The elevator waiting time recording unit 42 registers the waiting time and the boarding / alighting data ID in the waiting time data.

  Next, the elevator waiting / ride counter unit 41 proceeds to step S88, and searches the elevator hall management table for a place ID corresponding to the elevator ID of the boarding / alighting data. Then, the elevator waiting / ride counter unit 41 decreases the number of waiting corresponding to the place ID of the waiting data by one. At the same time, the elevator waiting / ride counter 41 deletes the boarding / alighting data ID from the waiting data boarding / exiting data ID list.

  If the determination (end) of the boarding / alighting data a is “leaving”, the elevator waiting / boarding counter unit 41 proceeds to step S88 and searches the elevator hall management table for a place ID corresponding to the elevator ID of the boarding / alighting data. Then, the elevator waiting / ride counter unit 41 decreases the number of waiting corresponding to the place ID of the waiting data by one. At the same time, the elevator waiting / ride counter 41 deletes the boarding / alighting data ID from the waiting data boarding / exiting data ID list.

  In step S89 following steps S83, S85, and S88, the elevator waiting / ride counter 41 updates the waiting data, and then notifies the terminal 43 of the number of rides and the waiting data. At this time, the elevator waiting / boarding counter unit 41 searches the elevator hall management table for the terminal address corresponding to the elevator ID of the boarding / alighting data, and notifies the terminal 43 of the searched terminal address of the boarding number data and the waiting data.

  When the terminal 43 receives the boarding number data and the waiting data from the elevator waiting / riding counter unit 41, the terminal 43 displays the elevator use information as shown in FIG. FIG. 29 is an image diagram of an example of an elevator usage information screen displayed on the terminal. The elevator usage information screen of FIG. 29 displays the current number of passengers for the three elevators at the center, the information of passengers waiting at the bottom, and the current time at the lower right.

  FIG. 30 is an explanatory diagram showing various data when the elevator usage information screen of FIG. 29 is displayed on the terminal. The number of passengers on the elevator usage information screen is the number of passengers with the corresponding elevator ID in the passenger number data. The number of rides “1” on the left of the elevator use information screen of FIG. 29 corresponds to the number of rides “1” of the elevator ID “100” in the number of rides data. The number of rides “0” at the center of the elevator usage information screen in FIG. 29 corresponds to the number of rides “0” of the elevator ID “101” in the number of rides data. Also, the number of rides “3” on the right of the elevator use information screen of FIG. 29 corresponds to the number of rides “3” of the elevator ID “102” in the number of rides data.

  The information on the waiting customers on the elevator usage information screen of FIG. 29 is obtained as follows, for example. First, the elevator waiting / riding counter 41 obtains corresponding getting-on / off data from the waiting data getting-on / off data ID list, and obtains the continuous reception data ID from each getting-on / off data.

  For example, in the case of the waiting data location ID “5” in FIG. 29, the elevator waiting / ride counter unit 41 obtains the getting on / off data ID “1, 2, 4, 5” from the getting on / off data ID list. The continuous reception data ID of the obtained boarding / alighting data ID “1” is “1”. The elevator waiting / ride counter unit 41 obtains corresponding reception data from the start point reception data ID of the continuous reception data ID. The start point reception data ID of the continuous reception data ID “1” in FIG. 30 is “1”.

  The elevator waiting / riding counter 41 obtains the time “10:10 on March 30, 2010” of the reception data ID “1”, and from the difference from the current time “10:15 on March 30, 2010” The waiting time (5 minutes) of the target with the tag ID “310010” is obtained. The elevator waiting / riding counter unit 41 similarly obtains the tag ID and the waiting time for other boarding / alighting data, takes out the tag ID having a waiting time of 3 minutes or more, and obtains the number of corresponding target IDs from the target management table. Seek and display.

  The terminal 43 is owned by a store clerk such as a department store, for example, to provide information to the passenger in the elevator hall based on the elevator usage information displayed on the terminal 43, and to give priority to the customer who has been waiting for a long time. It may be used for services such as guiding other customers.
