[Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6841379 Summary of the Invention [Problem to be solved by the invention]

[0004] The transmission characteristics of radio waves transmitted from a beacon device vary depending on the structure of the building and the installation conditions of the beacon device. As a result, the radio wave strength detected by a mobile terminal may also vary depending on the building. Furthermore, the detected radio wave strength may vary depending on the reception characteristics of the mobile terminal held by the user. For this reason, in the system of Patent Document 1, even if the user is at the boarding area, the radio wave strength from the beacon device does not exceed the threshold and a boarding area call is not registered. Alternatively, there is the problem that a boarding area call may be registered even if the user has no intention of boarding and is away from the boarding area.

[0005] The present disclosure has been made to solve the above-mentioned problems, and aims to provide an elevator system that performs appropriate automatic call registration by making it possible to change the threshold value depending on the building conditions and the mobile terminal carried by the elevator.

DETAILED DESCRIPTION OF THE INVENTION

[0009] The following detailed description will be given with reference to the drawings. Duplicate descriptions will be simplified or omitted as appropriate. In each drawing, the same reference numerals indicate the same or corresponding parts.

[0010] Embodiment 1 FIG. 1 is a configuration diagram of an elevator in an elevator system according to the first embodiment.

[0011] In Figure 1, an elevator shaft 1 runs through each floor of a building, and a machine room 2 is located directly above the elevator shaft 1. In addition, multiple landings 3 are provided on each floor of the building so as to face the elevator shaft 1.

[0012] A hoisting machine 4 is installed in the machine room 2, and a main rope 5 is wound around it.

[0013] The car 6 is supported on one side of the main ropes 5, and the counterweight 7 is supported on the other side of the main ropes 5. Therefore, when the hoisting machine 4 is driven, the car 6 and the counterweight 7 move up and down in opposite directions inside the hoistway 1.

[0014] A landing door 8 is installed at the entrance and exit of each of the multiple landings 3. A car door 9 is installed at the entrance and exit of the car 6. An infrared sensor 10 is also installed on the car door 9 to detect objects entering or exiting the car 6 through the entrance and exit of the car 6. A weighing device 11 is installed directly below the floor of the car 6 to detect the load acting on the floor of the car 6.

[0015] A hall-side beacon device 12 is disposed on each wall surface of the plurality of halls 3.

[0016] A control device 13 capable of controlling the entire elevator is installed in the machine room 2.

[0017] The base station 14 is located at a location away from the building. The mobile terminal 15 is carried by a person. The mobile terminal 15 is a device that can be carried by a person, such as a smartphone or tablet. In this system, the owner of the mobile terminal 15 can automatically register elevator calls using the mobile terminal 15. To register a call using the mobile terminal 15, a call registration system application must be installed in advance on the mobile terminal 15. This registration system application can be downloaded, for example, from the homepage of the maintenance company that manages the elevators. In the following explanation, the call registration system application will be simply referred to as the application. In addition, a car-side beacon device 16 is arranged inside the car 6.

[0018] Figure 2 shows the screen transitions that occur when the owner of mobile terminal 15 sets up an automatic call using an application. First, the owner selects the building for which automatic call registration is to be performed, for example, "Building A," on the screen shown in Figure 2(a). This displays the screen shown in Figure 2(b) for specifying two boarding floors.

[0019] On this screen, as shown in Figure 2(c), for example, the holder enters "1" and "5" as the two landing floors and touches the "OK" area. This allows the device to be set up to automatically request an UP call at the 1st floor landing and a car call to the 5th floor, as well as a DOWN call at the 5th floor landing and a car call to the 1st floor. Note that an UP call at the 1st floor landing is the same as a passenger pressing the UP button on the panel at the 1st floor landing. Also, a car call to the 5th floor is the same as a passenger pressing the button for the 5th floor on the panel inside the car where they plan to get off.

[0020] FIG. 3 is a conceptual diagram of a main part of an elevator in the elevator system according to the first embodiment.

[0021] As shown in Fig. 3, the hall-side beacon device 12 transmits radio waves toward the hall 3. The mobile terminal 15 receives the radio waves. When the received radio wave intensity exceeds a threshold, the mobile terminal 15 transmits car call request information by radio waves toward the control device 13. The control device 13 registers the car call based on this information.

[0022] For example, when a person carrying a mobile terminal 15 configured as shown in Fig. 2 approaches the platform beacon device 12 on the first floor, the platform UP call for the first floor and the car call for the fifth floor are automatically registered without any operation by the person carrying the mobile terminal 15. Also, when the person approaches the platform beacon device 12 on the fifth floor, the platform DOWN call for the fifth floor and the car call for the first floor are automatically registered without any operation by the person carrying the mobile terminal 15.

[0023] The reason why the received radio wave strength exceeds the threshold is to prevent the mobile terminal 15 from receiving weak radio waves and automatically registering a call even though the owner of the mobile terminal 15 has no intention of getting on the elevator and is away from the hall-side beacon device 12.

[0024] Next, automatic call registration will be described in detail. FIG. 4 is a block diagram showing a detailed configuration of control device 13 and mobile terminal 15 of the elevator system according to the first embodiment.

[0025] The control device 13 has an external communication unit 1301 , a call request receiving unit 1302 , an operation management unit 1303 , a control unit 1304 , and a hoist communication unit 1305 .

[0026] The external communication unit 1301 communicates with external devices via the Internet network 17. The call request receiving unit 1302 receives call request information via the external communication unit 1301. The operation management unit 1303 registers and manages the call in the car operation information based on the call request information received by the call request receiving unit 1302 and button press information on the landing panel and the car panel. The control unit 1304 generates drive information for controlling the drive of the hoist 4 and controls the landing door based on the car operation information. The hoist communication unit 1305 transmits drive information to the hoist 4. As a result, the hoist 4 is driven and moves the car 6 to the target landing. In this way, the control device 13 controls the operation of the car 6.

[0027] The mobile terminal 15 has a radio wave receiving unit 1501, a radio wave intensity measuring unit 1502, a call control unit 1503, a memory unit 1504, and an external communication unit 1505. The call control unit 1503 also has a threshold calculation unit 1506, a reference threshold database (hereinafter referred to as "DB") 1507, a correction threshold DB 1508, a hall-side radio wave intensity comparison unit 1509, a car-side radio wave intensity comparison unit 1510, a call request creation unit 1511, a call request transmission unit 1512, an abnormality determination unit 1513, and a correction unit 1514.

[0028] The radio wave receiving unit 1501 receives radio waves transmitted from the hall side beacon device 12 and the car side beacon device 16.

[0029] The radio wave intensity measurement unit 1502 measures the intensity of the radio wave received by the radio wave reception unit 1501. Note that the closer to the beacon device, the stronger the intensity of the radio wave received by the mobile terminal 15 becomes.

[0030] The threshold calculation unit 1506 sets the threshold using the reference threshold DB 1507 and the corrected threshold DB 1508. Specifically, the threshold is set as follows.

[0031] FIG. 5 is a diagram showing the format of data registered in the reference threshold DB 1507. As shown in FIG. The reference threshold DB 1507 associates a building 1507a, a bank 1507b, a floor number 1507c, a reference threshold 1507d, and beacon information 1507e. The beacon information 1507e, including UUID, Major, and Minor, is an identifier used in iBeacon (registered trademark) and is included in radio waves transmitted from the beacon device. The reference threshold DB 1507 corresponds to the beacon device, and the reference threshold 1507d is a value that is defined when the beacon device is installed. This value is fixed in the application.

[0032] FIG. 6 is a diagram showing the format of data registered in the correction threshold DB 1508. As shown in FIG. A building 1508a, a bank 1508b, a floor number 1508c, a correction threshold 1508d, and beacon information 1508e are associated with each other in the correction threshold DB 1508. The correction threshold DB 1508 corresponds to each mobile terminal, and the correction threshold 1508d is changeable.

[0033] The threshold calculation unit 1506 extracts the corresponding standard threshold 1507d and corrected threshold 1508d from the standard threshold DB 1507 and corrected threshold DB 1508 based on the beacon information in the received radio waves. Then, these are added together to set the threshold. Note that the floor numbers 1507c and 1508c are registered with the floor number where the hall-side beacon device 12 is installed in the case of the hall-side beacon device 12, and with the name of the "car" in the case of the car-side beacon device 16. Therefore, it is possible to determine whether the radio waves are from the hall-side beacon device 12 or the car-side beacon device 16 from the information on the floor numbers 1507c and 1508c corresponding to the beacon information 1507e and 1508e. Then, in the case of the radio waves from the hall-side beacon device 12, the threshold is sent to the hall-side radio wave intensity comparison unit 1509. In addition, in the case of the radio waves from the car-side beacon device 16, the threshold is sent to the car-side radio wave intensity comparison unit 1510.

[0034] The hall-side radio wave intensity comparison unit 1509 compares the threshold set in the threshold calculation unit 1506 with the radio wave intensity measured by the radio wave intensity measurement unit 1502. Also, the car-side radio wave intensity comparison unit 1510 compares the threshold set in the threshold calculation unit 1506 with the radio wave intensity measured by the radio wave intensity measurement unit 1502.

[0035] When the hall-side radio wave intensity comparison unit 1509 determines that the radio wave intensity exceeds the threshold, the call request creation unit 1511 creates call request information based on the table stored in the storage unit 1504 .

[0036] 7 shows a hall call pattern table 15041 stored in the storage unit 1504. In the hall call pattern table 15041, beacon information 15041a, a building 15041b, a bank 15041c, a boarding floor 15041d, and a movement direction 15041e are associated with each other.

[0037] 8 shows a car call pattern table 15042 stored in the storage unit 1504. In the car call pattern table 15042, beacon information 15042a, a building 15042b, a bank 15042c, a boarding floor 15042d, and a destination floor 15042e are associated with each other. The four pieces of relationship information relating to Building A in FIG. 7 and the four pieces of relationship information relating to Building A in FIG. 8 are set by the screen operations shown in FIG.

[0038] The call request creation unit 1511 extracts, from the table 15041, information on the boarding floor 15041d and information on the moving direction 15041e that match the received beacon information, and creates information on a hall call request. Also, the information on the boarding floor 15042d and the information on the destination floor 15042e that match the received beacon information are extracted from the table 15042, and car call request information is created.

[0039] The call request transmitting unit 1512 performs processing to transmit the created hall call request information and car call request information as call request information.

[0040] The external communication unit 1505 communicates wirelessly with external devices via the Internet network 17 .

[0041] The abnormality determination unit 1513 determines whether the comparison result in the car-side radio wave intensity comparison unit 1510 is abnormal or normal.

[0042] The correction unit 1514 receives the determination result from the abnormality determination unit 1513 and corrects the correction threshold 1508 d in the correction threshold DB 1508 .

[0043] FIG. 9 is a conceptual diagram for explaining the concept of determining an abnormality in the abnormality determining unit 1513. In FIG. As shown in Fig. 9(a), a platform-side beacon device 12 is installed at the platform and transmits radio waves. Fig. 9(b) is a diagram showing the relationship between the movement of a person and the radio wave intensity received by a mobile terminal 15.

[0044] Typically, the hall-side beacon device 12 is installed on the wall of the elevator hall, and a construction worker carrying a mobile terminal 15 moves toward the hall door 8 and measures the strength of the radio waves received. This is shown by the dotted line in Figure 9(b). This radio wave strength increases as the worker moves toward the hall door 8, but stabilizes once the worker reaches a certain position. Therefore, an expected reception range is set as a range within which it can be assumed that the carrier intends to board the car if they approach this position, and the radio wave strength at that position is used as the reference threshold. This reference threshold is shown by the dashed line in Figure 9(b).

[0045] However, in reality, the radio wave strength received by a mobile terminal varies depending on the reception sensitivity of the mobile terminal and the location of objects in the building. For example, because the reception sensitivity of the mobile terminal 15 of owner B is low, even if owner B enters the expected reception range to board an elevator, the radio wave strength may not exceed the reference threshold as shown in Figure 9(b). As a result, call request information is not created or transmitted. Conversely, for example, because owner A's mobile terminal 15 has high reception sensitivity, the radio wave strength may exceed the reference threshold as shown in Figure 9(b) simply by passing through the elevator hall, even though owner A is not within the expected reception range. As a result, call request information is created and transmitted. These types of phenomena constitute abnormalities.

[0046] Next, the operation of automatic call registration in the mobile terminal 15 will be described with reference to the flowchart of FIG.

[0047] First, in the mobile terminal 15, the radio wave receiving unit 1501 receives the radio wave transmitted from the hall side beacon device 12 (step S001). The threshold calculation unit 1506 calculates and sets a threshold (hereinafter, "hall-side threshold") using the reference threshold DB 1507 and the corrected threshold DB 1508 (step S002). Next, the hall-side radio wave intensity comparison unit 1509 determines whether the radio wave intensity received from the hall-side beacon device 12, measured by the radio wave intensity measurement unit 1502, exceeds the hall-side threshold value (step S003).

[0048] If it is determined in step S003 that the radio wave intensity exceeds the hall-side threshold, the call request creation unit 1511 creates call request information consisting of a hall call request and a car call request based on the table stored in the memory unit 1504 (step S004). Next, the call request transmitting unit 1512 transmits the created call request information to the control device 13 via the external communication unit 1505 (step S005). In the control device 13, the call request receiving unit 1302 receives the call request information via the external communication unit 1301, and the operation management unit 1303 registers the hall call and car call requests in the operation information. After that, the operation management unit 1303 transmits call registration completion information to the mobile terminal 15 via the external communication unit 1301, and the call registration completion information is received by the mobile terminal 15 (step S006). As a result, the application of the mobile terminal 15 displays information such as the call registration completion on the screen of the mobile terminal 15, and the owner can know that the call registration has been completed.

[0049] Next, the radio wave receiving unit 1501 determines whether or not it has received radio waves from the car-side beacon device 16 (step S007). When the car 6 moves to the boarding floor and the landing door 8 and car door 9 open, the radio wave receiving unit 1501 receives the radio waves transmitted from the car-side beacon device 16.

[0050] If it is determined in step S007 that a radio wave has been received, the threshold calculation unit 1506 sets a threshold (hereinafter, "car-side threshold") using the reference threshold DB 1507 and the corrected threshold DB 1508 (step S008).

[0051] Next, the car-side radio wave intensity comparison unit 1510 determines whether the radio wave intensity received from the car-side beacon device 16, measured by the radio wave intensity measurement unit 1502, exceeds the car-side threshold value (step S009). The radio wave intensity exceeds the car-side threshold when the holder gets on the car 6. When the holder is at the platform, the radio wave intensity is set not to exceed the car-side threshold even if it is received from the car-side beacon device 16.

[0052] If it is determined in step S009 that the car-side threshold value has been exceeded, the process ends.

[0053] If it is determined in step S003 that the radio wave intensity does not exceed the hall-side threshold, the radio wave receiving unit 1501 determines whether or not a radio wave has been received from the car-side beacon device 16 (step S010). If it is determined in step S010 that a radio wave has not been received, the process returns to step S003.

[0054] If it is determined in step S010 that the signal has been received, the threshold calculation unit 1506 sets the car-side threshold using the reference threshold DB 1507 and the correction threshold DB 1508 (step S011). Next, the car-side radio wave intensity comparison unit 1510 determines whether the radio wave intensity measured by the radio wave intensity measurement unit 1502 exceeds the car-side threshold value (step S012).

[0055] In step S012, when it is determined that the radio wave intensity exceeds the car-side threshold, this means that the owner of the mobile terminal 15 has boarded the car 6, even though a call request has not been created or transmitted. For example, this is the case when there is a fellow passenger, who has registered a hall call, and the car 6 has started moving.

[0056] This means that even though the owner of the mobile terminal 15 was within the assumed reception range of Fig. 9, the radio wave intensity from the hall-side beacon device 12 received by the mobile terminal 15 did not exceed the hall-side threshold. In other words, this is the case when the hall-side threshold is too high.

[0057] Therefore, if it is determined in step S012 that the radio wave intensity exceeds the car-side threshold, it is necessary to lower the hall-side threshold set in step S002. The abnormality determination unit 1513 determines that an abnormality has occurred, and the correction unit 1514 corrects the value of the correction threshold 1508d in the correction threshold DB 1508 so as to lower it (step S013).

[0058] Furthermore, if it is determined in step S007 that radio waves have not been received from the car-side beacon device 16, it is determined whether radio waves from the hall-side beacon device 12 have stopped being received (step S014). The mobile terminal 15 continues to receive radio waves even after receiving radio waves from the hall-side beacon device 12 and the radio wave strength exceeds the hall threshold. Therefore, if radio waves are subsequently no longer received, this may be because the user has moved away from the hall, as in the case of the user A in FIG. 9. In other words, it can be assumed that the user of the mobile terminal 15 has simply passed through the elevator hall and is not within the assumed reception range in FIG. 9, but the radio wave strength received by the mobile terminal 15 has exceeded the hall-side threshold. This is the case when the hall-side threshold is too low.

[0059] Therefore, in step S014, if it is determined that radio waves from the hall-side beacon device 12 are not received, that is, that reception is not possible, it is necessary to increase the hall-side threshold set in step S002. The abnormality determination unit 1513 determines that an abnormality has occurred, and the correction unit 1514 corrects the value of the correction threshold 1508d in the correction threshold DB 1508 so as to increase it (step S015).

[0060] In step S014, if it is not determined that radio waves from the hall-side beacon device 12 cannot be received, the process returns to step S007.

[0061] If it is determined in step S009 that the radio wave intensity does not exceed the car-side threshold, it is determined whether radio waves from the car-side beacon device 16 have been received (step S016). In step S007, the car door opens, and even after the mobile terminal 15 receives radio waves from the car-side beacon device 16, reception of radio waves continues. Thereafter, when the car door closes, the radio waves are blocked by the car door, and the mobile terminal 15 at the landing cannot receive radio waves from the car-side beacon device 16.

[0062] In step S016, if radio waves from the car-side beacon device 16 cannot be received, i.e., reception is not possible, this means that the car 6 has arrived at the boarding floor and the door has opened, but the holder of the mobile terminal 15 who made the call request has not boarded. In other words, it can be assumed that the radio wave intensity received by the mobile terminal 15 exceeds the hall-side threshold, even though the holder of the mobile terminal 15 is not within the assumed reception range in Fig. 9. This is the case when the hall-side threshold is too low.

[0063] Therefore, if it is determined in step S016 that radio waves from the car-side beacon device 16 cannot be received, the same process as in step S015 is performed. That is, the abnormality determination unit 1513 determines that an abnormality has occurred, and the correction unit 1514 corrects the value of the correction threshold value 1508d in the correction threshold value DB 1508 so as to increase it (step S017).

[0064] In a typical elevator, the car 6 is an enclosed space covered with metal. Therefore, the radio waves transmitted from the car-side beacon device 16 are not weakened by the influence of the building structure. Furthermore, since the radio waves are reflected by the walls of the car 6 and fly around inside the car, the radio wave strength is not likely to decrease due to the sensitivity of the mobile terminal 15. Therefore, it is not assumed that the owner of the mobile terminal 15 boarded the car 6, but the strength of the radio waves received from the car-side beacon device 16 was weak and did not exceed the car-side threshold.

[0065] 11 is a diagram showing hardware resources of the mobile terminal 15. The mobile terminal 15 includes, as hardware resources, a processor 1520, a memory 1521, and a wireless transmission / reception circuit 1522. Note that there may be a plurality of processors 1520 and memories 1521.

[0066] In the first embodiment, the functions of the storage unit 1504, the reference threshold DB 1507, and the correction threshold DB 1508 are performed by a memory 1521. The memory 1521 also stores a program that performs the processing of the flowchart in Fig. 10. Upon startup, this program runs on the processor 1520 and performs various processing functions. The functions of the radio wave receiving unit 1501 and the external communication unit 1505 are performed by a transmitting / receiving circuit 1522.

[0067] The processor 1520 is also called a CPU (Central Processing Unit), central processing unit, arithmetic unit, microprocessor, microcomputer, or DSP. The memory 1521 may be a semiconductor memory, a magnetic disk, a flexible disk, an optical disk, a compact disk, a minidisk, or a DVD. Usable semiconductor memory includes RAM, ROM, flash memory, EPROM, EEPROM, etc.

[0068] In this way, in the first embodiment, the radio wave intensity threshold used to determine whether or not to make a call request can be automatically adjusted to an appropriate value depending on the mobile terminal and the surrounding conditions. This makes it possible to avoid unnecessary car calls and the failure to make necessary car calls, thereby achieving optimal automatic call operation.

[0069] The numerical value by which the correction threshold is increased or decreased may be a fixed value, a numerical value based on a calculation formula, or a numerical value calculated by AI.

[0070] In the processing of steps S014 and S016, a period during which reception is not possible may be set in consideration of temporary car closure at the hall, for example, whether reception is not possible for 0.5 seconds.

[0071] The hardware resources of the mobile terminal 15 may be the hardware resources shown in Fig. 12. The mobile terminal 15 includes a processor 1520, a memory 1521, a transmission / reception circuit 1522, and dedicated hardware 1523. Some of the functions of the processor 1520 in Fig. 11 are performed by the dedicated hardware 1523. The dedicated hardware 1523 may be a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof.

[0072] Embodiment 2 Fig. 13 is a flowchart showing the operation of automatic call registration in the mobile terminal 15 in the second embodiment. In Fig. 13, after a call request is created and transmitted, if the radio wave intensity received from the car-side beacon device 16 does not exceed the car-side threshold value until the car door closes, it is determined that an abnormality has occurred. In Fig. 13, the same steps as in Fig. 10 are assigned the same numbers.

[0073] In FIG. 13, call registration is performed from step S001 to step S006. Thereafter, in step S007, it is determined whether or not radio waves are received from the car-side beacon device 16. If it is determined that radio waves have not been received, it is determined whether the car door 9 has been closed at the boarding floor (step S101). The operation management unit 1303 of the control device 13 registers the call request in step S005 in the operation information. Thereafter, the car 6 moves to the boarding floor, opens the door, and closes it. The operation management unit 1303 sends that information to the mobile terminal 15 at the time the door is closed. Therefore, if that information is received from the operation management unit 1303, it means that the car door 9 has been closed at the boarding floor.

[0074] In addition, when it is determined in step S101 that the car door is closed, it means that the car 6 has arrived at the boarding floor and the door has opened, but the holder of the mobile terminal 15 that made the call request has not boarded. That is, it is conceivable that the carrier of the mobile terminal 15 may have simply passed through an elevator hall and not entered the assumed reception range of Fig. 9, but the radio wave intensity received by the mobile terminal 15 may exceed the hall-side threshold. This can be determined as a case where the hall-side threshold is too low.

[0075] Therefore, if it is determined in step S101 that the car door is closed, it is necessary to increase the hall-side threshold value set in step S002. The abnormality determination unit 1513 determines that an abnormality has occurred, and the correction unit 1514 corrects the value of the correction threshold value 1508d in the correction threshold value DB 1508 so as to increase it (step S015).

[0076] If it is determined in step S101 that the car door has not been closed at the boarding floor, the process returns to step S007.

[0077] If it is determined in step S009 that the radio wave intensity does not exceed the car-side threshold, it is determined whether the car door has been closed, as in step S014 (step S102).

[0078] If it is determined in step S102 that the car door is closed, this means that the car 6 has arrived at the boarding floor and the door has opened, but the holder of the mobile terminal 15 who made the call request has not boarded. In other words, it can be assumed that the radio wave intensity received by the mobile terminal 15 has exceeded the hall-side threshold, even though the holder of the mobile terminal 15 is not within the expected reception range in Fig. 9. This can be determined to be a case where the hall-side threshold is too low.

[0079] Therefore, if it is determined in step S102 that the car door has closed, the abnormality determination unit 1513 determines that an abnormality has occurred, and the correction unit 1514 corrects the value of the correction threshold 1508d in the correction threshold DB 1508 to increase it (step S017).

[0080] In this way, by making a judgment based on information from the control device 13, for example, even if reception from the car-side beacon device 16 becomes impossible due to the car being temporarily closed at the landing, but the car door is then opened again, processing can be reliably continued.

[0081] Embodiment 3 Fig. 14 is a flowchart showing the operation of automatic call registration in the mobile terminal 15 in the third embodiment. In Fig. 14, after a call request is created and transmitted, if the radio wave intensity received from the car-side beacon device 16 does not exceed the car-side threshold within a certain time, it is determined that an abnormality has occurred. In Fig. 14, the same steps as in Fig. 10 are assigned the same numbers.

[0082] In FIG. 14, after the call registration is performed in steps S001 to S006, the timer of the mobile terminal 15 is started to start measuring the elapsed time (step S201). Thereafter, in step S007, it is determined whether or not a radio wave has been received from the car-side beacon device 16, and if not, it is determined whether or not a certain time has elapsed (step S202). The certain time here is a time set assuming that the holder of the mobile terminal 15 that made the car call request will board the car after the call registration.

[0083] When it is determined in step S202 that a certain time has elapsed, this means that the train has arrived at the boarding floor and the door of the car 6 has opened, but the holder of the mobile terminal 15 who made the call request has not boarded. In other words, it can be assumed that the radio wave intensity received by the mobile terminal 15 exceeds the hall-side threshold even though the holder of the mobile terminal 15 is not within the expected reception range in Fig. 9. This can be determined as a case where the hall-side threshold is too low.

[0084] Therefore, if it is determined in step S202 that a certain period of time has elapsed, it is necessary to increase the hall-side threshold value set in step S002. The abnormality determination unit 1513 determines that an abnormality has occurred, and the correction unit 1514 corrects the value of the correction threshold value 1508d in the correction threshold value DB 1508 so as to increase it (step S015).

[0085] If it is determined in step S007 that a radio wave has been received from the car-side beacon device 16, the car-side threshold is set in step S008. If it is determined in step S009 that the radio wave intensity does not exceed the car-side threshold, it is determined whether a certain time has elapsed (step S203), similar to step S202.

[0086] In step S203, if a certain time has elapsed, this means that the train has arrived at the boarding floor and the door of the car 6 has opened, but the holder of the mobile terminal 15 who made the call request has not boarded. In other words, it can be assumed that the radio wave intensity received by the mobile terminal 15 has exceeded the hall-side threshold, even though the holder of the mobile terminal 15 is not within the assumed reception range in Fig. 9. This can be determined to be a case where the hall-side threshold is too low.

[0087] Therefore, if it is determined in step S203 that a certain period of time has elapsed, the same process as step S015 is performed. That is, the abnormality determination unit 1513 determines that an abnormality has occurred, and the correction unit 1514 corrects the value of the correction threshold 1508d in the correction threshold DB 1508 so as to increase it (step S017).

[0088] In this way, by using the timer function of the mobile terminal 15, it is possible to simplify the determination of the occurrence of an abnormality.

[0089] Embodiment 4 FIG. 15 is a block diagram showing detailed configurations of the control device 13, the mobile terminal 15, and the server device 18 of the elevator system according to the fourth embodiment. 15 differs from the first embodiment in that the reference threshold DB is arranged in an external server device 18 instead of in the mobile terminal 15. In FIG. 15, the server device 18 includes an external communication unit 1801 that communicates with external devices via the Internet network 17, a control unit 1802, and a reference threshold DB 1803.

[0090] In this configuration, when calculating a threshold, threshold calculation unit 1506 attaches beacon information in the radio waves received by radio wave receiving unit 1501 and transmits a threshold information extraction request to server device 18. In server device 18, control unit 1802 accepts the threshold information extraction request via external communication unit 1801. Then, a reference threshold corresponding to the beacon information is extracted from reference threshold DB 1803 and transmitted via external communication unit 1801. The threshold calculation unit 1506 acquires the reference threshold transmitted via the external communication unit 1505. Then, it adds the reference threshold to the correction threshold extracted from the correction threshold DB 1508 corresponding to the beacon information, and sets the threshold.

[0091] The standard threshold DB corresponds to the beacon device and is common to the system. The registered standard thresholds do not change depending on the mobile terminal. Therefore, by arranging them in the common server device 18, it is possible to reduce the storage capacity of each mobile terminal 15.

[0092] Embodiment 5 FIG. 16 is a block diagram showing the control device 13, the mobile terminal 15, and the server device 18 of the elevator system according to the fifth embodiment. 16 differs from the first embodiment in that the reference threshold DB and the correction threshold DB are both located in an external server device 18 rather than in the mobile terminal 15. 16, the server device 18 includes an external communication unit 1801 that communicates with external devices via the Internet network 17, a control unit 1802, a reference threshold DB 1803, and a corrected threshold DB 1804.

[0093] Each mobile terminal 15 has a unique terminal identifier. In the corrected threshold DB 1804, the building, bank, floor number, corrected threshold, and beacon information are associated with the terminal identifier.

[0094] In this configuration, threshold calculation unit 1506 transmits a threshold information extraction request to server device 18 together with the beacon information and its own terminal identifier. In server device 18, control unit 1802 accepts the threshold information extraction request via external communication unit 1801. Then, a reference threshold corresponding to the beacon information is extracted from reference threshold DB 1803. Also, a correction threshold corresponding to the beacon information and the terminal identifier is extracted from correction threshold DB 1804. Then, the reference threshold and correction threshold are transmitted via external communication unit 1801.

[0095] The threshold calculation unit 1506 acquires the reference threshold and the corrected threshold sent via the external communication unit 1505, adds them together, and sets the threshold.

[0096] Furthermore, when modifying unit 1514 modifies the correction threshold in correction threshold DB 1804, it transmits a correction threshold modification request accompanied by beacon information, the modification value, and the terminal identifier to server device 18. In server device 18, control unit 1802 accepts the correction threshold modification request via external communication unit 1801. Then, the correction threshold in correction threshold DB 1804 corresponding to the beacon information and the terminal identifier is changed to the received modification value.

[0097] Although the corrected threshold DB is information corresponding to each individual mobile terminal, by storing it in a common server device 18, the storage capacity of each mobile terminal 15 can be further reduced. [Industrial Applicability]
