Embodiment 1 FIG.
FIG. 1 is a configuration diagram of a user recognition system according to the first embodiment.

The user recognition system 1 is applied to the elevator system 2.

The elevator system 2 is applied to buildings. The building has a plurality of floors. In the elevator system 2, the hoistway passes through each floor of the building. In the elevator system 2, landings are provided on each floor of the building. The elevator system 2 includes a car. The car is provided to be able to move up and down inside the hoistway.

The elevator system 2 includes a registration unit 3. The registration unit 3 is a part that registers a user's call in the car based on the notified call mode. The call mode is a call mode corresponding to the user. The call mode includes information such as whether or not the user uses the movement aid and the type of the movement aid. The operation of the car in which the call of the user is registered is controlled based on the call mode.

The user recognition system 1 includes a wireless tag 4, a security gate 5, and a call control device 6.

The wireless tag 4 is carried by the user. The wireless tag 4 stores identification information. The identification information is information for identifying a user. The wireless tag 4 includes an element for acquiring current position information. The position information is, for example, three-dimensional coordinates (x, y, z). The position information is acquired by, for example, a satellite positioning system or an indoor positioning system. The identification information and the position information are transmitted from the wireless tag 4 by a wireless signal at predetermined time intervals.

The wireless tag 4 is provided on a wheelchair on which a user rides. Wheelchairs are examples of mobility aids that include wheels.

The security gate 5 is provided on at least one of a plurality of floors of the building. The security gate 5 is provided, for example, on the entrance floor. The entrance floor is, for example, a floor where an entrance of a building is provided. The security gate 5 is provided on a route leading to the landing. The security gate 5 is a device that restricts a user on a route leading to the landing by opening and closing. In the elevator system 2, the landing on the floor where the security gate 5 is provided is surrounded by a structure such as a wall to prevent a user who does not pass through the route from entering. The security gate 5 includes a receiving unit 7.

The receiving unit 7 is a unit that receives identification information from the wireless tag 4. The receiving unit 7 is, for example, an antenna. The security gate 5 is closed when the receiving unit 7 has not received the identification information meeting the predetermined criteria.

(4) The receiving unit 7 is a unit that acquires the position information of the wireless tag 4. The identification information and the position information of the wireless tag 4 are obtained by a wireless signal transmitted from the wireless tag 4. The receiving unit 7 stores the acquired identification information and position information. The receiving unit 7 includes an element that acquires information on the strength of a wireless signal received from the wireless tag 4. The strength of the wireless signal is, for example, an RSSI (Received Signal Strong Strength Indication) value. The receiving unit 7 calculates an RSSI value from the position information of the wireless tag 4, for example. The receiving unit 7 is connected to the call control device 6 so as to transmit the identification information, the position information, and the information of the RSSI value.

The call control device 6 includes a detection unit 8, a generation unit 9, a reference storage unit 10, and a determination unit 11.

The detection unit 8 is a unit that detects a user who intends to enter the landing based on the information of the RSSI value acquired from the reception unit 7. The detection unit 8 is connected to the generation unit 9 so that the detection result can be transmitted.

The generation unit 9 is a unit that generates trajectory information of the trajectory on which the wireless tag 4 moves from the position information of the wireless tag 4. The trajectory information is information indicating the trajectory of the moving wireless tag 4. The orbit information is, for example, information indicating a change in the height of the wireless tag 4 from the floor with respect to time. The trajectory information includes, for example, information on the average value of the height, information on the amplitude of the vibration at the height, or information on the frequency of the vibration at the height.

The criterion storage unit 10 is a part for storing information of criterion registered in advance. The registered criterion indicates a criterion for the trajectory of the moving wireless tag 4. In the registered criteria, for example, an allowable range of the height of the wireless tag 4 from the floor surface is set. Alternatively, for example, the allowable range of the amplitude or frequency of the vibration of the height of the wireless tag 4 from the floor is set in the registered standard. The registered reference corresponds to the position where the movement assisting device and the wireless tag 4 are provided on the moving assisting device. The reference storage unit 10 stores information of the reference to be registered and the call mode in association with each other.

The determination unit 11 is a unit that determines whether the trajectory of the wireless tag 4 represented by the trajectory information generated by the generation unit 9 matches the criterion registered in the criterion storage unit 10. The determination unit 11 is connected to the reference storage unit 10 so as to be able to acquire registered reference information.

The determination unit 11 is a unit that specifies a call mode based on the determination. The designation of the call mode by the determination unit 11 is performed when the identification information received by the reception unit 7 conforms to a predetermined standard. When the determination unit 11 determines that the trajectory represented by the trajectory information generated by the generation unit 9 matches the registered standard, the call mode stored in the reference storage unit 10 in association with the criterion is determined. It is specified. On the other hand, when the determination unit 11 does not determine that the trajectory represented by the trajectory information generated by the generation unit 9 matches the registration criterion, the normal call mode is designated. The normal call mode is, for example, a call mode corresponding to a user who does not use the movement assisting device.

(4) An outline of the operation of the user recognition system 1 will be described with reference to FIG.

に お い て In normal times, the security gate 5 is closed. At this time, the security gate 5 does not allow a person who enters the building from the entrance to enter the landing. A user in a wheelchair approaches the security gate 5. The receiving unit 7 acquires identification information and position information from the wireless tag 4 provided on the wheelchair.

The call control device 6 acquires the identification information and the position information from the receiving unit 7. The receiving unit 7 sequentially stores identification information and position information obtained from wireless signals transmitted at predetermined time intervals. The receiving unit 7 accumulates by storing, for example, identification information and position information for n times. The detection unit 8 detects a user who intends to enter the landing based on the information of the RSSI value acquired from the reception unit 7.

When the detecting unit 8 does not detect the user, the call control device 6 discards the obtained identification information and position information. The receiving unit 7 discards the stored identification information and position information. At this time, the generation unit 9 does not generate the trajectory information.

On the other hand, when the detecting unit 8 detects a user, the generating unit 9 generates trajectory information from the position information of the wireless tag 4 acquired from the receiving unit 7. The security gate 5 determines whether the identification information conforms to a predetermined criterion. If the identification information meets the predetermined criteria, the security gate 5 opens. The determination unit 11 determines whether the trajectory of the wireless tag 4 represented by the trajectory information generated by the generation unit 9 matches the criterion registered in the criterion storage unit 10. The determination unit 11 specifies a call mode based on the determination. The determination unit 11 notifies the designated call mode to the registration unit 3 of the elevator system 2. The registration unit 3 registers the user's call in the car based on the notified call mode.

(4) The user enters the landing through the route where the security gate 5 is provided. The user waits at the landing for the arrival of the car in which the call has been registered. Thereafter, the user moves to the destination floor using the car.

Subsequently, an example of the wheelchair 12 provided with the wireless tag 4 will be described with reference to FIG.
FIG. 2 is a diagram illustrating an example of a wheelchair provided with the wireless tag according to the first embodiment.

無線 As shown on the left side of FIG. 2, the wireless tag 4 is provided on, for example, a handle 13 of a wheelchair 12.

In this case, the height of the wireless tag 4 does not change due to the movement of the wheelchair 12. That is, the wireless tag 4 moves on a track whose height from the floor is constant. In this case, the allowable range of the height of the wireless tag 4 from the floor is set based on the reference stored in the reference storage unit 10 as the reference corresponding to the position where the wheelchair 12 and the wireless tag 4 are provided.

無線 As shown on the right side of FIG. 2, the wireless tag 4 is provided, for example, on wheels 14 of a wheelchair 12.

In this case, the movement of the wheelchair 12 causes the wireless tag 4 to rotate together with the wheels 14. That is, the wireless tag 4 moves on a track that vibrates in the height direction from the floor surface with an amplitude corresponding to the position provided on the wheel 14 and a frequency corresponding to the rotation speed of the wheel 14. In the reference stored in the reference storage unit 10 as the reference corresponding to the position where the wheelchair 12 and the wireless tag 4 are provided in this case, the allowable range of the amplitude or frequency of the vibration of the wireless tag 4 from the floor is set. You.

Subsequently, detection of a user by the detection unit 8 will be described with reference to FIG.
FIG. 3 is a diagram illustrating an example of detection of a user by the detection unit according to the first embodiment.

In FIG. 3, the horizontal axis represents the RSSI value acquired by the receiving unit 7. In the detection unit 8, a threshold value for the RSSI value is set. In this example, the threshold is -10 dBm.

(4) When the time during which the RSSI value obtained from the receiving unit 7 exceeds the threshold is equal to or longer than a predetermined time, the detecting unit 8 determines that the user has an intention to enter the landing. At this time, the detection unit 8 detects a user trying to enter the landing.

On the other hand, when the time during which the RSSI value obtained from the reception unit 7 exceeds the threshold is shorter than a predetermined time, or when the RSSI value does not exceed the threshold, the detection unit 8 allows the user to enter the landing. Judge that there is no intention to do so. At this time, the detection unit 8 does not detect a user trying to enter the landing.

Subsequently, generation of the trajectory information by the generation unit 9 will be described with reference to FIG.
FIG. 4 is a diagram illustrating an example of generation of trajectory information by the generation unit according to the first embodiment.

に お い て In the upper graph of FIG. 4, the vertical axis represents the RSSI value acquired by the call control unit from the receiving unit 7. The horizontal axis represents the horizontal distance from the receiving unit 7 to the wireless tag 4.

The RSSI value depends on the distance from the receiving unit 7 to the wireless tag 4 and the like. The RSSI value increases as the distance from the receiving unit 7 to the wireless tag 4 decreases. For this reason, even when the wireless tag 4 is moving on a track whose height from the floor is constant, the RSSI value changes depending on the horizontal distance from the receiving unit 7 to the wireless tag 4. Therefore, the generation unit 9 determines the horizontal distance from the reception unit 7 to the wireless tag 4 so that the RSSI value is constant when the wireless tag 4 is moving on a track with a constant height from the floor. Normalize the RSSI value. The horizontal distance from the receiving unit 7 to the wireless tag 4 is calculated based on the position information of the wireless tag 4.

に お い て In the lower graph of FIG. 4, the vertical axis represents the normalized RSSI value. The horizontal axis represents the horizontal distance from the receiving unit 7 to the wireless tag 4.

(4) The influence of the horizontal position of the wireless tag 4 on the floor surface on the RSSI value is corrected by normalization. For this reason, the normalized RSSI value represents information on the height of the wireless tag 4 from the floor surface, regardless of the horizontal position on the floor surface of the wireless tag 4. When the wireless tag 4 is moving in the horizontal direction, the generation unit 9 acquires the time information together with the position information of the wireless tag 4. The generation unit 9 generates information representing a change in the height of the wireless tag 4 from the floor with respect to time from the information on the height of the wireless tag 4 from the floor and the information on the time as the track information.

Subsequently, the determination by the determination unit 11 will be described with reference to FIG.
FIG. 5 is a diagram illustrating an example of a determination by the determining unit according to the first embodiment.

に お い て In the upper graph of FIG. 5, the horizontal axis represents the amplitude of the vibration of the trajectory represented by the trajectory information generated by the generation unit 9.

Here, the amplitude of the vibration is calculated as a level expression of the minimum value of the amount of vibration with reference to the maximum value of the amount of vibration in the trajectory information. For example, when the trajectory information is represented by a normalized RSSI value, the amplitude of the vibration is the difference between the minimum value and the maximum value of the normalized RSSI value.

For example, when the wireless tag 4 is provided on the wheel 14 of the wheelchair 12, the allowable range of the amplitude of the vibration is set based on the reference stored in the reference storage unit 10. In this example, the tolerance range is between -13 dB and -7 dB. When the amplitude of the vibration of the trajectory represented by the trajectory information generated by the generation unit 9 is included in the permissible range, the determination unit 11 determines that the trajectory meets the criterion.

In the lower graph of FIG. 5, the horizontal axis represents the frequency of the orbital vibration represented by the orbital information generated by the generating unit 9.

For example, when the wireless tag 4 is provided on the wheel 14 of the wheelchair 12, the allowable range of the vibration frequency is set based on the reference stored in the reference storage unit 10. In this example, the allowable range is a range between 30 cycles / min and 50 cycles / min. When the vibration frequency of the trajectory represented by the trajectory information generated by the generation unit 9 falls within the allowable range, the determination unit 11 determines that the trajectory meets the criterion.

Alternatively, for example, when the wireless tag 4 is provided on the handle 13 of the wheelchair 12, the allowable range of the height of the wireless tag 4 is set based on the reference stored in the reference storage unit 10. The height of the wireless tag 4 is represented by, for example, a normalized RSSI value. When the height of the wireless tag 4 represented by the trajectory information generated by the generation unit 9 is included in the permissible range, the determination unit 11 determines that the trajectory meets the criterion.

Next, the operation of the user recognition system 1 will be described with reference to FIG.
FIG. 6 is a flowchart illustrating an example of an operation of the user recognition system according to the first embodiment.

に お い て In step ST1, the receiving unit 7 acquires the identification information and the position information from the wireless tag 4. Thereafter, the operation of the user recognition system 1 proceeds to step ST2.

In step ST2, the call control device 6 acquires the RSSI value, the identification information, and the position information from the receiving unit 7. Thereafter, the operation of the user recognition system 1 proceeds to step ST3.

In step ST3, the call control device 6 determines whether or not the detection unit 8 detects a user trying to enter the hall. When the result of the determination is Yes, the operation of the user recognition system 1 proceeds to step ST4. When the determination result is No, the call control device 6 discards the identification information and the position information acquired from the receiving unit 7. Thereafter, the operation of the user recognition system 1 ends.

In step ST4, the generation unit 9 generates trajectory information from the RSSI value and the position information acquired from the reception unit 7. Thereafter, the operation of the user recognition system 1 proceeds to step ST5.

In step ST5, the determination unit 11 determines whether the trajectory represented by the trajectory information generated by the generation unit 9 matches the criterion stored in the criterion storage unit 10. If the result of the determination is Yes, the operation of the user recognition system 1 proceeds to step ST6. When the result of the determination is No, the operation of the user recognition system 1 proceeds to step ST7.

In step ST6, the determination unit 11 specifies a call mode corresponding to a criterion to which the trajectory represented by the trajectory information generated by the generation unit 9 conforms. After that, the determination unit 11 notifies the registration unit 3 of the specified call mode. Thereafter, the operation of the user recognition system 1 ends.

判定 In step ST7, the determination unit 11 specifies a normal call mode. After that, the determination unit 11 notifies the registration unit 3 of the specified call mode. Thereafter, the operation of the user recognition system 1 ends.

As described above, the user recognition system 1 according to the first embodiment includes the wireless tag 4, the receiving unit 7, the generating unit 9, and the determining unit 11. The wireless tag 4 is provided on a user's movement assisting device. The receiving unit 7 receives identification information for identifying a user from the wireless tag 4. The receiving unit 7 acquires the position information of the wireless tag 4. The generating unit 9 generates orbit information of the wireless tag 4 from the position information acquired by the receiving unit 7. The determination unit 11 determines whether the trajectory represented by the trajectory information generated by the generation unit 9 matches the criteria registered in advance. The determination unit 11 specifies a call mode based on the determination to register a call.

The wireless tag 4 moves on a specific trajectory according to the type and part of the movement assisting tool on which the wireless tag 4 is provided. For this reason, the call is registered in the elevator car by the natural movement of the user who moves using the movement assisting tool to enter the elevator hall. Thereby, the user can register the call by the operation of approaching using the elevator to use the elevator without performing the predetermined operation for registering the call in the predetermined area.

ご The operation of the car in which the user's call is registered is controlled based on the call mode. The call mode includes information such as whether or not the user uses the movement aid and the type of the movement aid. Further, the call of the user is made based on the trajectory information of the wireless tag 4 that moves with the movement of the user. For this reason, the user can use the car that is driven in accordance with the moving aid used, without performing a call registration operation such as holding a card. As a result, convenience for the user is improved. The burden on a user riding on a mobility aid such as the wheelchair 12 and a user pushing the wheelchair 12 is reduced. Also, the user can register the call smoothly. For this reason, traffic congestion of the user that occurs in the elevator system 2 linked to the security gate 5 is reduced.

The user recognition system 1 specifies a call mode based on a wireless signal from the wireless tag 4. For this reason, the user recognition system 1 does not require a camera.

無線 The wireless tag 4 is provided on the wheel 14 of the wheelchair 12, which is a movement aid.

The wireless tag 4 rotates together with the wheels 14. When the wheels 14 are rotating and moving stably, the vibration of the track of the wireless tag 4 is stabilized. Thereby, the accuracy of the determination by the determination unit 11 is improved.

(4) The user recognition system 1 includes the detection unit 8. The detection unit 8 detects a user who is going to enter the elevator hall based on the intensity of the signal received by the reception unit 7 from the wireless tag 4. The generation unit 9 generates trajectory information when the detection unit 8 detects a user.

The generator 9 generates trajectory information for the wireless tag 4 of the user determined by the detector 8 to have an intention to enter the landing. As a result, generation of unnecessary trajectory information is omitted.

{Circle around (4)} The generator 9 generates orbit information from the intensity of the signal received by the receiver 7 from the wireless tag 4 and the position information.

For example, in an indoor positioning system, etc., high-accuracy position information may not be obtained. At this time, even when the accuracy in the height direction of the position information alone is not sufficient, the generation unit 9 can improve the accuracy of the trajectory information by combining the position information and the information of the change in the strength of the wireless signal. it can.

In addition, when the amplitude of the vibration of the trajectory represented by the trajectory information generated by the generation unit 9 is within the range set by the reference registered in advance, the determination unit 11 determines that the trajectory matches the criterion. Is determined. In this case, the determination unit 11 specifies a call mode corresponding to the criterion.

振幅 Vibration amplitude can be calculated from the maximum and minimum values of the amount of vibration. The determination unit 11 does not require processing such as image recognition. Therefore, the determination unit 11 can reduce the amount of calculation involved in the determination.

In addition, when the frequency of the vibration of the trajectory represented by the trajectory information generated by the generation unit 9 is within a range set in a reference registered in advance, the determination unit 11 determines that the trajectory conforms to the criterion. Then, the judgment is made. In this case, the determination unit 11 specifies a call mode corresponding to the criterion.

The frequency of vibration can be calculated from a sequence of values of the amount of vibration. The determination unit 11 does not require processing such as image recognition. Therefore, the determination unit 11 can reduce the amount of calculation involved in the determination.

移動 The movement assisting device is a device that assists the user in moving, and may be any device that can get on the elevator car. The movement aid may be a walker, a walking car, or an electric wheelchair.

The wireless tag 4 may acquire the position information by receiving wireless signals transmitted from a plurality of transmitters. Each of the plurality of transmitters is provided, for example, on the entrance floor.

位置 The position information of the wireless tag 4 may be obtained by a position detecting device. The position detecting device is provided, for example, on the entrance floor. The position detecting device may be, for example, a plurality of receivers that receive a wireless signal transmitted from the wireless tag 4. At this time, the wireless tag 4 does not need to acquire the position information. In this case, the receiving unit 7 acquires the position information of the wireless tag 4 from the position detecting device.

The call control device 6 may store the user identification information in association with the destination floor information. The call control device 6 may notify the registration unit 3 of destination floor information together with the designated call mode. The registration unit 3 may simultaneously register a call to the destination floor.

The user recognition system 1 may share the wireless tag 4 provided in another system with the system.

The elevator system 2 may include a plurality of cars. At this time, the elevator system 2 includes a group management device. The group management device may select a car to which the call is assigned based on the call mode notified to the registration unit 3.
