Embodiment 1.
The elevator system is applied to, for example, a building provided with one or more cars.

FIG. 1 is a schematic diagram showing an outline of the elevator system according to the first embodiment. FIG. 1 illustrates a case where a plurality of cars are provided in a building.

The elevator system includes a wireless communication device 1, a communication terminal 2, a group management device 3, a control device 4, and a display device 5. The wireless communication device 1 is installed in, for example, a room in a building, an aisle, an elevator hall, or the like. The wireless communication device 1 may be installed on a plurality of floors, for example. The control device 4 is provided corresponding to each car, for example. The display device 5 is installed, for example, in an elevator hall or the like. The group management device 3 is electrically connected to the control device 4 and the display device 5.

In FIG. 1, the plurality of wireless communication devices 1 are distinguished by adding alphabetic characters to the symbols. In FIG. 1, as the wireless communication device 1, a wireless communication device 1A and a wireless communication device 1B installed on the same floor are illustrated. The wireless communication device 1A is installed, for example, in a passage in a building. The wireless communication device 1B is installed in an elevator hall. The wireless communication device 1A is installed at a position away from the elevator hall. The wireless communication device 1A is installed at least at a position where the communication range of the wireless communication device 1A does not overlap with that of the wireless communication device 1B.

The communication terminal 2 has a portable housing. The communication terminal 2 is carried by a user, for example. The communication terminal 2 has a function of performing wireless communication with the wireless communication device 1 and the group management device 3, for example.

The communication terminal 2 has a "call generation unit". The “call generation unit” generates a temporary call or a main call, triggered by communication with the wireless communication device 1. The communication terminal 2 transmits the generated call to the group management device 3. The temporary call is a call that can be canceled before the assigned car arrives at the landing. This call is a call that cannot be canceled before the assigned car arrives at the hall.

The group management device 3 determines, for example, a car dispatch plan. The control device 4 controls the movement of the corresponding car according to the vehicle allocation plan, for example. On the display device 5, for example, information indicating the assigned car corresponding to the call is displayed.

FIG. 2 is a functional block diagram of the elevator system according to the first embodiment.

As shown in FIG. 2, the communication terminal 2 includes a detection unit 21, a state acquisition unit 22, a recording unit 23, a boarding probability calculation unit 24, a temporary call generation unit 25, a final call generation unit 26, a learning unit 27, and a notification unit 28. And a communication unit 29. The temporary call generation unit 25 and the main call generation unit 26 are included in the “call generation unit”.

FIG. 3 is a hardware configuration diagram of the communication terminal.

The communication terminal 2 is, for example, a smartphone, a mobile phone, a tablet terminal, a PDA (Personal Data Assistant), or the like. As shown in FIG. 3, the communication terminal 2 has, for example, a processor 2a, a memory 2b, a communication device 2c, a sensor 2d, a display 2e, and a speaker 2f.

The wireless communication device 1 performs wireless communication by a communication method such as Wi-Fi (registered trademark) or Bluetooth (registered trademark), for example. The wireless communication device 1 periodically transmits information to the communication terminal 2 existing within the communication range by wireless communication. The information includes, for example, the installation floor and installation position of the wireless communication device 1.

The installation floor and the installation position of the wireless communication device 1 are recorded in advance in the internal memory of the wireless communication device 1. The installation floor of the wireless communication device 1 is represented by, for example, an ID determined by “the number of floors from the bottom floor+1”. The installation position of the wireless communication device 1 is represented by, for example, an ID that can specify whether the installation position is a landing or a position away from the landing. For example, the fact that the installation position is the hall is represented by the ID "1". For example, the fact that the installation position is away from the hall is represented by the ID "2".

The detection unit 21 is realized by, for example, the communication device 2c. The detection unit 21 waits for communication from the wireless communication device 1. When the information including the installation floor and the installation position is received from the wireless communication device 1 for the first time, the detection unit 21 detects that the communication terminal 2 has entered the communication range of the wireless communication device 1.

The detection unit 21 determines that the communication terminal 2 has left the communication range of the wireless communication device 1 when a certain time has elapsed after the information including the installation floor and the installation position is not received from the wireless communication device 1. To detect.

When the detection unit 21 once detects the exit of the wireless communication device 1 out of the communication range and then receives the information including the installation floor and the installation position from the wireless communication device 1 again, the communication terminal 2 causes the wireless communication to be performed. It is detected that the device 1 has entered the communication range.

Hereinafter, detecting that the communication terminal 2 has entered the communication range of the wireless communication device 1 is also referred to simply as “detecting the wireless communication device 1”.

When detecting the wireless communication device 1, the detection unit 21 records a set of the detection date and time, the installation floor of the wireless communication device 1 and the installation position of the wireless communication device 1 in the detection recording table 101. That is, the detection unit 21 records the detection date and time, the installation floor, and the installation position in association with each other each time the wireless communication device 1 is detected.

The state acquisition unit 22 acquires the state of the communication terminal 2 by using the value measured by the sensor 2d, for example. The sensor 2d is, for example, an acceleration sensor, a gyro sensor, a magnetic sensor, a direction sensor, a GPS (Global Positioning System), or an atmospheric pressure sensor. Further, the state acquisition unit 22 may acquire the state of the communication terminal 2 by using a value such as the radio field intensity of wireless communication acquired by the communication device 2c.

The state of the communication terminal 2 is, for example, the moving state of the housing of the communication terminal 2. That is, the state acquisition unit 22 acquires the moving state of the user who carries the communication terminal 2.

The state acquisition unit 22 starts acquisition of the state of the communication terminal 2 upon detection of the wireless communication device 1A installed at a position away from the hall. The state acquisition unit 22 ends the acquisition of the state of the communication terminal 2 when the wireless communication device 1B installed in the hall is detected, for example. Further, the state acquisition unit 22 ends the acquisition of the state of the communication terminal 2 when the maximum travel time T _MAX has elapsed since the start of the acquisition of the state of the communication terminal 2, for example. The state acquisition unit 22 periodically communicates until, for example, the wireless communication device 1B provided at the hall is detected, or until the maximum travel time T _MAX has elapsed since the start of acquisition of the state of the communication terminal 2. Continue to acquire the status of the terminal 2.

The maximum travel time T _MAX is, for example, the maximum value of the time required for the user to move from the communication range of the wireless communication device 1A to the communication range of the wireless communication device 1B. The maximum moving time T _MAX is determined by the learning unit 27, for example.

Hereinafter, the t-th acquired state after the state acquisition unit 22 starts acquiring the state of the communication terminal 2 is referred to as x _t . The state x _t is represented by, for example, x _t =(d _t , v _t ) as a set of the azimuth d _t and the velocity v _t of the communication terminal 2. The azimuth d _t is represented by, for example, an angle based on a certain direction. For example, when the north is used as a reference, 90 degrees clockwise represents east, 180 degrees south, and 270 degrees west. The unit of the velocity v _t is, for example, meters per second. The state x _t may include, in addition to the azimuth d _t and the speed v _t , a relative distance that the communication terminal 2 has moved after the state acquisition unit 22 starts acquiring the state.

The state acquisition unit 22 records the state x _t in the state recording table 102 together with the detection date and time of the wireless communication device 1A and the installation floor of the wireless communication device 1A each time the acquisition of the state is completed. That is, the state acquisition unit 22 records the detection date and time, the installation floor, and the state x _t in association with each other each time the acquisition of the state of the communication terminal 2 is completed.

The recording unit 23 is realized by, for example, the memory 2b. The recording unit 23 holds information necessary for generating a temporary call and a main call. The recording unit 23 holds, for example, a destination floor table 100, a detection recording table 101, a state recording table 102, and a boarding probability threshold table 103.

FIG. 4 is an example of a destination floor table in the first embodiment.

As shown in FIG. 4, the destination floor table 100 includes a set of a departure floor and a destination floor of a user carrying the communication terminal 2. The contents of the destination floor table 100 are recorded in the communication terminal 2 in advance, for example. The content of the destination floor table 100 may be different for each communication terminal 2, for example.

FIG. 5 is an example of the detection record table in the first embodiment.

As illustrated in FIG. 5, the detection record table 101 includes a set of a detection date and time, a detected installation floor of the wireless communication device 1 and an installation position of the wireless communication device 1. For example, in the detection record of the wireless communication device 1A, the installation position is represented by the ID "1". For example, in the detection record of the wireless communication device 1B, the installation position is represented by the ID “2”.

FIG. 6 is an example of the state recording table in the first embodiment.

As shown in FIG. 6, the state recording table 102 shows the detection date and time of the wireless communication device 1A that triggered the acquisition of the state, the installation floor of the wireless communication device 1A, and the state acquired by the state acquisition unit 22. It includes a set of sequences {x _t }. The series of states {x _t } indicates, for example, how the user carrying the communication terminal 2 has moved.

For example, in the first row from the top of the state recording table 102 shown in FIG. 6, a series including four states is recorded. The first acquired state in this sequence is x ₁ =(180,0.5). The second acquired state in this sequence is x ₂ =(180,0.5). The third acquired state in this sequence is x ₃ =(90,0.5). The fourth acquired state in this sequence is x ₄ =(90,0).

FIG. 7 is an example of a boarding probability threshold table according to the first embodiment.

As shown in FIG. 7, the boarding probability threshold table 103 includes a set of time slots, floors, and a boarding probability threshold P _MIN . The floor item in the boarding probability threshold table 103 indicates the departure floor. The threshold P _MIN is used to generate a temporary call. The unit of the threshold P _MIN is, for example, percent. The contents of the boarding probability threshold table 103 are recorded in the communication terminal 2 in advance, for example. The contents of the boarding probability threshold table 103 are common regardless of the communication terminal 2, for example.

The boarding probability calculation unit 24 is realized, for example, by the processor 2a executing a program recorded in the memory 2b. The boarding probability calculator 24 calculates the boarding probability every time the state acquisition unit 22 acquires a new state, for example.

Hereinafter, a method of calculating the boarding probability will be described.

The boarding probability calculator 24 first calculates the degree of difference between the latest state series acquired by the state acquisition section 22 and the past state series recorded in the state recording table 102. The latest state series is not yet recorded in the state recording table 102 at this point. The dissimilarity is defined by the following equation (1).

The latest state sequence is represented by {x _t } (1≦t≦T _LAST ). x _{t is, x t = (d t,} v t) is expressed by. T _LAST indicates the number of states included in the latest state series. For example, if the latest state sequence is {(175,0.5),(185,0.5),(180,0.5),(95,0.5),(85,0)} , T _LAST =5. That is, x _t (t=T _LAST ) is the latest state among the states acquired by the state acquisition unit 22.

The sequence of past states is represented by { _x't } ( _{1≤t≤T'MAX} ). x′ _t is represented by x′ _t =(d′ _t , v′ _t ). T′ _MAX indicates the number of states included in each series recorded in the state recording table 102. For example, in the case of the series recorded in the first row from the top of the state recording table 102 shown in FIG. 6, T′ _MAX =4. That is, x′ _t (t=T′ _MAX ) is the last acquired state among the past states included in the series at a certain detection date and time.

The outermost parenthesized portion of the equation (1) is the root mean square of the difference between the latest state acquired by the state acquisition unit 22 and the state recorded in the state recording table 102. Expression (1) means the minimum value among the values in the parentheses calculated under different conditions. The dissimilarity is the minimum value among the values in the parentheses calculated for all combinations of L and k.

L in Expression (1) indicates the number of states compared between the latest state series and the past state series. L is an integer that satisfies 2≦L≦min (T _LAST , T′ _MAX ).

K in Expression (1) is a number indicating which L states among the plurality of states included in the series of past states are to be compared. Specifically, of the plurality of states included in a certain sequence, the (k−2)+1th to kth states are used. k is an integer that satisfies L≦k≦T′ _MAX .

Hereinafter, a specific example of calculating the dissimilarity according to Expression (1) will be described. In this specific example, a case will be described in which the degree of difference from the series of states recorded in the first row from the top of the state recording table 102 shown in FIG. 6 is calculated.

For example, the latest state sequence is {(175,0.5), (185,0.5),(180,0.5),(95,0.5),(85,0)}. In this case, T _LAST =5. On the other hand, _T'MAX =4.

First, L is determined in order to calculate the degree of difference from a series of two states having different states. From 2≦L≦min (T _LAST , T′ _MAX ), L becomes 2, 3, or 4. The case of L=2 will be described below.

From the latest state series, L states are used for calculation in ascending order. When L=2, {(d _TLAST-1 , v _TLAST-1 ), (d _TLAST , v _TLAST )}={(95, 0.5), (85, 0)} is used to calculate the dissimilarity. Used.

Next, it is determined which two states are used among the states included in the series of states in the first row from the top of the state recording table 102. From L≦k≦T′ _MAX , k becomes 2, 3 or 4.

For example, when k=2, the first and second states among the states included in the series of states in the first row from the top of the state recording table 102 are used. That is, {(d′ ₁ , v′ ₁ ), (d′ ₂ , v′ ₂ )}={(180, 0.5), (180, 0.5)} is used to calculate the dissimilarity.

For example, when k=3, the second and third states among the states included in the series of states in the first row from the top of the state recording table 102 are used. That is, {(d′ ₂ , v′ ₂ ), (d′ ₃ , v′ ₃ )}={(180, 0.5), (90, 0.5)} is used to calculate the dissimilarity.

For example, when k=4, the third and fourth states among the states included in the series of states in the first row from the top of the state recording table 102 are used. That is, {(d′ ₃ , v′ ₃ ), (d′ ₄ , v′ ₄ )}={(90, 0.5), (90, 0)} is used to calculate the dissimilarity.

As in the above specific example, the minimum value among the values of the root mean square calculated by changing L and k is determined as the degree of difference.

The boarding probability calculation unit 24 extracts, from the state recording table 102, the detection date and time when the installation floor is the same as the installation floor of the wireless communication device 1A detected this time and the degree of difference is less than or equal to the threshold D _MAX . The number of extracted detection dates and times is represented by N _A. D _MAX is determined by the learning unit 27, for example. When extracting the detection date and time, the time zone or the day of the week may be limited. For example, when the behavior of the user changes depending on the time of day, such as the high possibility of using the elevator when going to work and the low time of using the elevator when it is not working, and the like. By limiting to the detection date and time on the same day of the week, the boarding probability can be calculated more accurately.

Of the detection records recorded in the detection record table 101, the boarding probability calculation unit 24 has the same installation floor as the installation floor of the wireless communication device 1A detected this time, the installation position is the hall, and is extracted. The detection record recorded from the detection date and time until the maximum moving time T _MAX elapses is extracted. The number of detection records extracted is denoted by N _B. Boarding probability calculation unit 24 _calculates the value of _N B / N _A × 100 as boarding probability. The unit of the boarding probability is, for example, percent.

The temporary call generation unit 25 is realized, for example, by the processor 2a executing a program recorded in the memory 2b. The temporary call generation unit 25 executes the following operation each time the boarding probability calculation unit 24 calculates the boarding probability. The temporary call generation unit 25 acquires the boarding probability threshold P _MIN corresponding to the current date and time from the boarding probability threshold table 103. The provisional call generation unit 25 has not generated a provisional call since the detection of the wireless communication device 1A that triggered the calculation of the ride probability, and the ride probability calculated by the ride probability calculation unit 24. Is greater than or equal to the threshold P _MIN , a temporary call is generated. The temporary call generation unit 25 supplies the generated temporary call to the communication unit 29. The tentative call includes, for example, a terminal ID that can identify the communication terminal 2, a departure floor, a destination floor, and information such as the time to reach the landing. The departure floor is the installation floor of the wireless communication device 1A. The destination floor is a floor associated with the departure floor in the destination floor table 100. Time until arriving at the landing to be included in the temporary call is a value obtained by subtracting the current time from the sum obtained by adding the time T _A with respect to the detection time of the radio communication apparatus 1A. The time T _A is the time from the detection unit 21 detecting the wireless communication device 1A to the arrival of the user at the landing.

Hereinafter, a method of calculating the time T _A will be described.

The temporary call generation unit 25 generates the movement time table 104 between the wireless communication devices from the detection record table 101. The travel time table 104 shows the travel time between the wireless communication devices 1. As shown in FIG. 8, the travel time table 104 includes a set of detection date and time of the wireless communication device 1A, detection date and time of the wireless communication device 1B, and a time difference. In the travel time table 104, the detection unit 21 detects the wireless communication device 1A installed on the departure floor and then the detection unit 21 detects the wireless communication device 1B installed on the departure floor within the maximum travel time T _MAX. For each case, the date and time of each detection is recorded. The time difference in the travel time table 104 is the difference between the detection date and time of the wireless communication device 1A and the detection date and time of the wireless communication device 1B. The unit of the time difference is seconds, for example.

The time T _A is calculated as the sum of the average value of the time differences recorded in the travel time table 104 and the preset time T _B. The time T _B is the time from the detection unit 21 detecting the wireless communication device 1B to the arrival of the user at the hall. The time T _B is a value that is uniquely determined based on the distance from the installation position of the wireless communication device 1B to the elevator hall door, for example. Time T _B, for example, the general value obtained by dividing the moving speed of the person a distance from the installation position of the wireless communication apparatus 1B to the landing door. When there are a plurality of landing doors, the time T _B is determined, for example, based on the average value of the lengths of the routes from the installation position of the wireless communication device 1B to the respective landing doors. Incidentally, if the moving time table 104 is empty, using the maximum movement time _{T MAX} as the time _{T A.}

The main call generation unit 26 is realized, for example, by the processor 2a executing a program recorded in the memory 2b. The main call generation unit 26 generates a main call when the detection unit 21 detects the wireless communication device 1B installed in the hall. The main call generation unit 26 supplies the generated main call to the communication unit 29. This call includes, for example, information such as the ID of the communication terminal 2, the departure floor, the destination floor, and the time to arrive at the hall. The departure floor is the installation floor of the wireless communication device 1B. The destination floor is a floor associated with the departure floor in the destination floor table 100. The time to arrive at the hall included in this call is time T _B. In order to prevent the main call from being generated by the detection unit 21 detecting the wireless communication device 1B on the destination floor when the user gets off the elevator car on the destination floor, the main call generation unit 26 , The main call is not generated for a certain period after the main call is generated.

The learning unit 27 is realized, for example, by the processor 2a executing a program recorded in the memory 2b. The learning unit 27 determines the maximum travel time T _MAX and the difference threshold D _MAX each time this call is generated. That is, the learning unit 27 updates the maximum moving time T _MAX and the threshold D _MAX based on the learning result. However, until the main call is generated for the first time, initial values recorded in advance in the memory 2b are used as the maximum travel time T _MAX and the threshold value D _MAX of the dissimilarity. The initial value is a positive number of appropriate size.

When the wireless communication device 1B on the same installation floor is detected before the time K×T _MAX elapses after the wireless communication device 1A is detected, the learning unit 27 determines that the difference t _DIFF between the detected dates and times is the current one. If it is larger than T _MAX , then T _MAX =t _DIFF . K is a natural number of appropriate size. If t _DIFF is equal to or _smaller than the current T _MAX , the learning unit 27 does not update T _MAX .

When the state of the communication terminal 2 is continuously acquired until the wireless communication device 1B is detected, the learning unit 27 determines that if the difference d calculated by Expression (1) is larger than the current D _MAX , D Let _MAX =d. If the difference d is equal to or less than the current D _MAX , the learning unit 27 does not update D _MAX .

The notification unit 28 is realized by, for example, at least one of the display 2e and the speaker 2f of the communication terminal 2. The notification unit 28 may be a wearable device connected to the communication terminal 2 by wireless communication or the like. The notification unit 28 notifies the user of the information indicating the assigned car supplied from the communication unit 29, as described later.

The communication unit 29 is realized by, for example, the communication device 2c. The communication device 2c performs wireless communication by a communication method such as Wi-Fi (registered trademark) or Bluetooth (registered trademark), for example. The communication unit 29 transmits the temporary call supplied from the temporary call generation unit 25 or the main call supplied from the main call generation unit 26 to the group management device 3. Further, the communication unit 29 supplies the notification unit 28 with information indicating the assigned car received from the group management device 3, as described later. The standard used by the communication unit 29 for communication with the group management device 3 may be different from the standard used for communication with the wireless communication device 1.

As shown in FIG. 2, the group management device 3 includes a communication unit 31, a call registration unit 32, and a vehicle allocation plan management unit 33.

FIG. 9 is a hardware configuration diagram of the group management device.

As illustrated in FIG. 9, the group management device 3 includes, for example, a processor 3a, a memory 3b, a wireless device 3c, and an interface 3d. The interface 3d is electrically connected to the control device 4 and the display device 5.

The communication unit 31 is realized by, for example, the wireless device 3c. The communication unit 31 performs wireless communication by a communication method such as Wi-Fi (registered trademark) or Bluetooth (registered trademark), for example. The communication unit 31 receives a temporary call or a main call from the communication terminal 2.

The call registration unit 32 is realized, for example, by the processor 3a executing a program recorded in the memory 3b. The call registration unit 32 calculates the arrival time at the hall corresponding to the temporary call or the main call by adding the time until the vehicle arrives at the hall included in the temporary call or the main call to the current date and time. The call registration unit 32 determines an assigned car for a new call based on the departure floor, the destination floor, the arrival time at the hall, and the vehicle allocation plan 110 described later. The call registration unit 32 determines a car for which the waiting time of the temporary call and the main call for which the assigned car has already been determined is the shortest as the assigned car for the new call. The call waiting time is the time from when the communication terminal 2 arrives at the hall on the departure floor until the assigned car corresponding to the call arrives at the departure floor. The call registration unit 32 supplies the vehicle allocation plan management unit 33 with a call type, a terminal ID, a departure floor, a destination floor, an arrival time at a landing, and a set of assigned cars. The call type is information indicating either a temporary call or a main call.

The vehicle allocation plan management unit 33 is realized, for example, by the processor 3a executing a program recorded in the memory 3b. The vehicle allocation plan management unit 33 holds, in the memory 3b, information regarding the assigned temporary call and main call for each car as the vehicle allocation plan 110. That is, the vehicle allocation plan 110 is generated for each car.

FIG. 10 is an example of a vehicle allocation plan according to the first embodiment.

FIG. 10 illustrates a car dispatch plan 110 for a certain car. As shown in FIG. 10, the vehicle allocation plan 110 includes the call type, the terminal ID of the communication terminal 2, the departure floor, the destination floor, and the arrival time at the hall calculated by the call registration unit 32.

When the call registration unit 32 supplies the call type, the terminal ID, the departure floor, the destination floor, the arrival time at the landing, and the set of assigned cars from the call registration unit 32, the vehicle allocation plan management unit 33 assigns the information included in the set to the assignment. Add to the car dispatch plan 110. However, when the main call with the same terminal ID is already registered in the vehicle allocation plan 110 of any one of the cars, the vehicle allocation plan management unit 33 does not add the information included in the group to the vehicle allocation plan 110 of the assigned car. If a temporary call having the same terminal ID is already registered in the car dispatch plan 110 of any one of the cars, the vehicle dispatch plan management unit 33 deletes the temporary call and then allocates the information included in the set to the allocation. Add to the car dispatch plan 110.

As described later, when the current floor and the moving direction of the car are supplied from the control device 4, the vehicle allocation plan management unit 33 determines that the stop floor of the car is the departure floor or the destination floor from the vehicle allocation plan 110 of the car. , And delete the call that is already past the arrival time at the hall. Further, the vehicle allocation plan management unit 33 deletes, from the vehicle allocation plans 110 of all the cars, the tentative call that has already arrived at the landing point at the present time. The vehicle allocation plan management unit 33 supplies the vehicle allocation plan 110 updated as described above to the control device 4.

The control device 4 refers to the vehicle allocation plan 110 of the corresponding car supplied from the group management device 3. The control device 4 stops the car on the departure floor of the temporary call and the main call to which the car is assigned based on the car dispatch plan 110 of the corresponding car until the arrival time at the landing. When a car is assigned to a plurality of calls having the same departure floor, the control device 4 stops the car until the latest arrival time at the landing. The control device 4 stops the car for a predetermined time after arriving at the destination floor of this call. When the car arrives at the floor where the car is located or when the car departs from the floor where the car is located, the control device 4 supplies the current floor and the moving direction of the car to the group management device 3.

The display device 5 informs the user by displaying the car to which the main call is assigned, which is determined by the group management device 3, on the screen.

FIG. 11 is a sequence diagram showing an operation example of the elevator system according to the first embodiment. Hereinafter, with reference to FIG. 11, an operation flow of the entire system when a user carrying the communication terminal 2 arrives at the elevator hall through the passage will be described. It is assumed that the wireless communication device 1A is installed in the passage.

When the user enters the communication range of the wireless communication device 1A installed in the passage, the detection unit 21 of the communication terminal 2 detects the wireless communication device 1A (step S1). Each time the communication terminal 2 acquires the state of the communication terminal 2 by the state acquisition unit 22, the boarding probability calculation unit 24 calculates the boarding probability. If the probability of boarding is equal to or greater than the threshold value P _MIN , the communication terminal 2 causes the temporary call generation unit 25 to generate a temporary call (step S2). The communication terminal 2 transmits a temporary call to the group management device 3 by the communication unit 29 (step S3).

When the group management device 3 receives the temporary call from the communication terminal 2 through the communication unit 31, the group management device 3 determines the assigned car using the call registration unit 32 (step S4). The group management device 3 updates the vehicle allocation plan 110 by the vehicle allocation plan management unit 33.

When the user enters the communication range of the wireless communication device 1B installed in the hall, the detection unit 21 of the communication terminal 2 detects the wireless communication device 1B (step S5). The communication terminal 2 generates a main call by the main call generation unit 26 (step S6). The communication terminal 2 transmits the main call to the group management device 3 by the communication unit 29 (step S7). The communication unit 2 uses the learning unit 27 to determine the maximum travel time T _MAX and the difference threshold D _MAX (step S8).

When the communication unit 31 receives the main call from the communication terminal 2, the group management device 3 determines the assigned car by using the call registration unit 32 (step S9). The group management device 3 updates the vehicle allocation plan 110 by the vehicle allocation plan management unit 33. The group management device 3 displays the assigned car on the display device 5 (step S10). The group management device 3 transmits information indicating the assigned car to the communication terminal 2 (step S11). The communication terminal 2 notifies the user of the assigned car by the notification unit 28 (step S12).

FIG. 12 is a flowchart showing temporary call registration according to the first embodiment. Hereinafter, the operation of the communication terminal 2 from the detection of the wireless communication device 1A to the generation of the temporary call will be described in detail with reference to FIG.

When the detection unit 21 detects the wireless communication device 1A, the communication terminal 2 records the detection date and time, and the set of the installation floor and installation position of the detected wireless communication device 1A in the detection recording table 101 (step S21). The communication terminal 2 periodically acquires the status by the status acquisition unit 22 (step S22). The communication terminal 2 calculates the boarding probability using the acquired state (step S23). The communication terminal 2 determines whether or not the provisional call has been generated since the detection of the wireless communication device 1A that triggered the calculation of the boarding probability, and the boarding probability is equal to or greater than the threshold value P _MIN. (Step S24).

When the condition of step S24 is satisfied, the communication terminal 2 generates a temporary call (step S25). After step S25, the process of step S26 is performed. If the condition of step S24 is not satisfied, the process of step S26 is performed without performing the process of step S25.

In step S26, it is determined whether or not the maximum movement time T _MAX has elapsed since the state was acquired. When it is determined in step S26 that the maximum movement time T _MAX has not elapsed since the state was acquired, the process of step S27 is performed. In step S27, the detection unit 21 determines whether or not the wireless communication device 1B has been detected. When it is determined in step S27 that the wireless communication device 1B is detected, the communication terminal 2 ends the acquisition of the state and records the sequence of the states acquired up to that time in the state recording table 102 (step S28).

When it is determined in step S26 that the maximum movement time T _MAX has elapsed since the state was acquired, the process of step S28 is performed. When it is determined in step S27 that the wireless communication device 1B is not detected, the process of step S22 is performed.

According to the first embodiment described above, the communication terminal 2 has a portable housing, acquires the moving state of the housing, and calculates the boarding probability to the elevator from the moving state of the housing. That is, the boarding probability can be calculated with high accuracy by considering the moving state of the user. The communication terminal 2 determines whether or not to generate a call based on the calculated boarding probability, and transmits the generated call to the group management device 3 by wireless communication. The group management device 3 receives from the communication terminal 2 a call generated based on the probability of getting on the elevator calculated by the communication terminal 2 having a portable case from the state of the case, and assigns the assigned car to the call. Decide and update the car dispatch plan. For this reason, it is possible to suppress the occurrence of unnecessary calls while enabling the call registration at a place away from the hall. As a result, the operation efficiency of the elevator can be improved.

Further, according to the first embodiment, the movement state of the housing includes at least one of the acceleration, the speed, the direction, and the movement distance after the acquisition of the movement state is started. Therefore, the boarding probability can be calculated with higher accuracy.

Further, according to the first embodiment, the communication terminal 2 is called when the calculated boarding probability is equal to or higher than a preset threshold value P _MIN and when the wireless communication device 1B provided at the elevator hall is detected. To generate. Therefore, it is possible to suppress the occurrence of unnecessary calls.

Moreover, according to the first embodiment, when the communication terminal 2 detects the wireless communication device 1A provided in a place other than the elevator hall in the building, the communication terminal 2 starts acquiring the moving state of the housing. After that, the communication terminal 2 has passed the maximum travel time T _MAX between the wireless communication devices 1 until it detects the wireless communication device 1B provided in the elevator hall or after starting the acquisition of the moving state of the housing. Until then, the moving state of the housing is continuously acquired. For this reason, since the state is acquired only during a necessary period, it is possible to prevent the processing load of the communication terminal 2 from increasing.

Further, according to the first embodiment, communication terminal 2 updates maximum travel time T _MAX based on the learning result. Therefore, the period during which the acquisition of the moving state of the housing is continued can be set more appropriately.

Moreover, according to the first embodiment, the communication terminal 2 records the movement state of the housing acquired in the past. The communication terminal 2 detects the number of times of detection of the wireless communication device 1A provided in a place other than the landing that triggered the acquisition of a moving state in which the degree of difference between the latest moving state of the housing and the latest moving state is less than or equal to a threshold value. And the boarding probability is calculated based on the past detection count of the wireless communication device 1B provided in the hall. Therefore, the boarding probability can be calculated with high accuracy.

Moreover, according to the first embodiment, the communication terminal 2 updates the threshold value D _{MAX of the} difference degree based on the learning result. Therefore, the boarding probability can be calculated with higher accuracy.

Further, according to the first embodiment, the communication terminal 2 calculates the boarding probability each time the movement state of the housing is acquired. Therefore, it is possible to suppress the occurrence of unnecessary calls.

Further, according to the first embodiment, the communication terminal 2 determines the moving time to the hall based on the current date and time, the detection date and time of the wireless communication apparatus 1, and the previously recorded moving time from the wireless communication apparatus 1 to the hall. A call including the calculated time and the information indicating the travel time to the hall is generated. The group management device 3 calculates the arrival time of the chassis at the landing based on the information indicating the current date and time and the travel time to the landing included in the call received from the communication terminal 2, and arrives at the landing in the dispatch plan 110. Include time. Therefore, the operation efficiency of the elevator can be improved.

Further, according to the first embodiment, the group management device 3 deletes from the vehicle allocation plan 110 a call whose arrival time at the landing has already passed. Therefore, the operation efficiency of the elevator can be improved.

Further, according to the first embodiment, the communication terminal 2 determines that the landing area is based on the time difference between the detection date and time of the wireless communication apparatus 1A provided at a place other than the landing and the detection date and time of the wireless communication apparatus 1B provided at the landing. The travel time from the wireless communication device 1A provided in a place other than the above to the hall is calculated. Therefore, the operation efficiency of the elevator can be improved.

Embodiment 2.
The second embodiment shows a configuration in which the time T _A and the maximum travel time T _MAX are calculated based on the distance between the wireless communication device 1 and the landing.

The functional block diagram of the elevator system in the second embodiment is the same as that in FIG.

In the second embodiment, the information periodically transmitted from the wireless communication device 1 to the communication terminal 2 includes, for example, the installation floor of the wireless communication device 1, the installation position of the wireless communication device 1, and the wireless communication. The distance from device 1 to the landing is included. Note that, instead of the wireless communication device 1 itself transmitting the distance to the hall, other devices that collectively transmit the distance from each of the wireless communication devices 1 in the building to the hall to the communication terminal 2 are installed. May be.

When detecting the wireless communication device 1, the detection unit 21 records a set of the detection date and time, the installation floor of the wireless communication device 1 and the installation position of the wireless communication device 1 in the detection recording table 101. Further, when the detection unit 21 detects the wireless communication device 1, a set of the installation floor of the wireless communication device 1, the installation position of the wireless communication device 1, and the distance from the wireless communication device 1 to the hall will be described later. Record at 105.

The distance from the wireless communication device 1 to the landing is, for example, the length of the route from the installation position of the wireless communication device 1 to the landing door of the elevator. The distance from the wireless communication device 1A to the hall is, for example, the length of the route from the installation position of the wireless communication device 1A to the hall door. The distance from the wireless communication device 1B to the hall is, for example, the length of the route from the installation position of the wireless communication device 1B to the hall door. When there are a plurality of landing doors, the average value of the length of the route from the installation position of the wireless communication device 1 to each landing door is set as the distance from the wireless communication device 1 to the landing.

The recording unit 23 holds, for example, a destination floor table 100, a detection recording table 101, a state recording table 102, a boarding probability threshold table 103, and a distance table 105.

FIG. 13 is an example of the distance table according to the second embodiment.

As illustrated in FIG. 13, the distance table 105 includes a set of the installation floor of the wireless communication device 1, the installation position of the wireless communication device 1, and the distance from the wireless communication device 1 to the hall. For example, the installation position of the wireless communication device 1A is represented by an ID of "1". For example, the installation position of the wireless communication device 1B is represented by the ID “2”. The unit of the distance to the landing is, for example, meters.

_A method of calculating the time T _{A in} the second embodiment will be described. The temporary call generation unit 25 extracts, from the state recording table 102, a series of states acquired at the installation floor included in the information transmitted by the wireless communication device 1A. The temporary call generation unit 25 calculates the average of the speeds included in the states in the extracted series. The temporary call generation unit 25 calculates a value obtained by dividing the distance from the wireless communication device 1A to the hall by the average speed as the time T _A. However, if there is no series of states acquired on the installation floor, the time T _A from the detection of the wireless communication device 1A to the arrival at the hall is the same as the maximum travel time T _MAX .

A method of calculating the maximum travel time T _{MAX in} the second embodiment will be described. The learning unit 27, based on the distance table 105, a difference between the distance from the wireless communication device 1A to the hall on the installation floor of the wireless communication device 1B detected by the detection unit 21 and the distance from the wireless communication device 1B to the hall. To calculate. The learning unit 27 extracts a series of states acquired on the installation floor of the wireless communication device 1B. The learning unit 27 extracts the minimum value of the speed included in the states in the extracted series. However, the minimum value of the speed is set to a value larger than 0. The learning unit 27 calculates a value obtained by dividing the difference in distance by the minimum value of speeds as the maximum travel time T _MAX .

According to the second embodiment described above, communication terminal 2 calculates maximum travel time T _MAX based on the distance from wireless communication device 1 to the hall. Therefore, even when the installation position of the wireless communication device 1 installed in the building differs depending on the floor, the maximum travel time T _MAX can be calculated with high accuracy.

Further, according to the second embodiment, the communication terminal 2 calculates the travel time from the wireless communication device 1A provided at a place other than the landing to the landing, based on the distance from the wireless communication device 1 to the landing. Therefore, even when the installation position of the wireless communication device 1 is installed in a building it is different depending floors can calculate the time T _A with high accuracy.

Embodiment 3.
The third embodiment shows a configuration in which the threshold P _MIN of boarding probability on each floor is calculated by the group management device 3 and transmitted to the communication terminal 2 via the wireless communication device 1.

FIG. 14 is a functional block diagram of the elevator system according to the third embodiment.

As shown in FIG. 14, in the third embodiment, the group management device 3 includes a communication unit 31, a call registration unit 32, a vehicle allocation plan management unit 33, a call recording unit 34, and a threshold value calculation unit 35. The group management device 3 is connected to the wireless communication device 1 by wire communication or wireless communication.

The call recording unit 34 is realized by, for example, the memory 3b. The call recording unit 34 holds, for example, the call record table 111.

FIG. 15 is an example of a call record table in the third embodiment.

As shown in FIG. 15, the call record table 111 includes a set of a terminal ID, a departure floor, a destination floor, a temporary call reception time, and a main call reception time.

When both the tentative call reception time and the main call reception time exist, as in the case where the terminal ID is 0001, it indicates that the group management device 3 has received both the tentative call and the main call from the terminal.

As in the case where the terminal ID is 0002, there is a tentative call reception time, and when the main call reception time is blank, the group management device 3 has received the tentative call from the terminal and has not yet received the main call. Indicates that there is no. At this moment, the arrival time at the hall corresponding to the temporary call has not passed.

When the reception time of the tentative call is “x” and the main call reception time is present as in the case where the terminal ID is 0003, the group management device 3 does not receive the tentative call from the terminal and only the main call is received. Is received.

When the temporary call reception time is present and the main call reception time is “x” as in the case where the terminal ID is 0004, the group management device 3 received the temporary call from the terminal, but the call to the hall Indicates that the call was not received even after the arrival time. That is, in this case, it means that the temporary call has been deleted from the vehicle allocation plan 110.

The vehicle allocation plan management unit 33 updates the call record table 111 of the call recording unit 34 every time the vehicle allocation plan 110 is updated.

When the temporary call is added to the vehicle allocation plan 110, the vehicle allocation plan management unit 33 newly adds a set of the terminal ID, the departure floor, the destination floor, the temporary call reception time, and the main call reception time to the call record table 111. At this time, the temporary call reception time is the current date and time, and the main call reception time is blank.

When the main call is added to the vehicle allocation plan 110, the vehicle allocation plan management unit 33 determines whether a group having the same terminal ID, the same floor as the departure floor, and the destination floor and having a blank main call reception time is present in the call record table 111. Check if When the group exists, the vehicle allocation plan management unit 33 records the current date and time at the main call reception time which is blank. If the set does not exist, the vehicle allocation plan management unit 33 newly adds a set of the terminal ID, the departure floor, the destination floor, the temporary call reception time, and the main call reception time to the call record table 111. At this time, the temporary call reception time is "x" and the main call reception time is the current date and time.

When deleting a provisional call that has already arrived at the landing at the current time from the vehicle allocation plan 110, the vehicle allocation plan management unit 33 has the same terminal ID, departure floor, and destination floor, and the main call reception time is blank. The selected group is selected from the call record table 111. The vehicle allocation plan management unit 33 records "x" at the main call reception time of the set.

The threshold value calculation unit 35 is realized, for example, by the processor 3a executing a program recorded in the memory 3b. The threshold value calculation unit 35 records a candidate P of the threshold value P _MIN of boarding probability in the memory 3b in advance. Candidate P is, for example, a value from 10% to 100% in steps of 10%. The threshold calculator 35 evaluates the average waiting time for each candidate P. The threshold value calculation unit 35 supplies the candidate P having the minimum average waiting time to the wireless communication device 1 as the threshold value P _MIN of the boarding probability.

FIG. 16 is a functional block diagram of the threshold value calculation unit in the third embodiment.

As shown in FIG. 16, the threshold value calculation unit 35 includes a virtual call generation unit 351, a simulation unit 352, and a threshold value determination unit 353.

The virtual call generation unit 351 generates virtual call information necessary for waiting time evaluation based on the call record table 111. The virtual call information includes a set of call type, departure floor, destination floor, and call occurrence time. Hereinafter, the virtual call generation unit 351 will be described in detail.

The virtual call generation unit 351 first determines from the call record table 111 that the tentative call reception time is from the same time as the current time until a certain period of time elapses and that the main call reception time exists or the main call reception The number of provisional calls that occur at a time “x” per day is calculated. Similarly, the virtual call generation unit 351 detects that the main call reception time is from the same time as the current time until a certain time elapses from the call record table 111, and the provisional call reception time exists or the provisional call is received. The number of occurrences of main calls for which the reception time is “x” is calculated per day. The number of such temporary calls or main calls generated is calculated for each set of the departure floor and the destination floor.

FIG. 17 is another example of the call record table in the third embodiment. A specific example of the number of call occurrences calculated from the call record table 111 will be described with reference to FIG. In this specific example, the current date and time is 08:21:00 on 2016/12/09. In addition, the above-mentioned fixed time is set to 10 minutes. In this case, when the temporary call reception time is from 08:21:00 to 10 minutes elapses, and the main call reception time exists, or the temporary call reception time is “x”, The number will be three. Also, the number of main calls for which the main call reception time is from 08:21:00 to 10 minutes have elapsed, and the provisional call reception time exists or the provisional call reception time is “x”. Will be three.

Then, the virtual call generation unit 351 generates a series of virtual temporary calls and virtual main calls so as to satisfy the above-described number of occurrences for each set of the departure floor and the destination floor. At this time, as the call occurrence time, a random time from the same time as the current time until a fixed time elapses is set.

The simulation unit 352 determines an assigned car for a series of virtual temporary calls and virtual main calls generated by the virtual call generation unit 351 under the condition that a certain candidate P is set as the threshold value P _MIN . At this time, the virtual tentative call is randomly deleted with the probability of the candidate P. The assigned car is not determined for the deleted virtual temporary call. The simulation unit 352 calculates the average waiting time of the main call when the assigned car operates.

The threshold determination unit 353 determines the candidate P having the minimum average waiting time calculated by the simulation unit 352 as the threshold P _MIN of boarding probability.

The wireless communication device 1 periodically provides the communication terminal 2 existing within the communication range with information including the installation floor of the wireless communication device 1, the installation position of the wireless communication device 1 and the threshold P _{MIN of the} boarding probability. Send.

When detecting the wireless communication device 1, the detection unit 21 records a set of the detection date and time, the installation floor of the wireless communication device 1 and the installation position of the wireless communication device 1 in the detection recording table 101. Further, the detecting unit 21 supplies the boarding probability threshold value P _MIN received from the wireless communication device 1 to the temporary call generating unit 25.

The temporary call generation unit 25 has not generated a temporary call after the wireless communication device 1A that triggered the calculation of the boarding probability has been detected, and the boarding probability calculated by the boarding probability calculation unit 24 has been detected. If it is equal to or _larger than the threshold value P _{MIN of the} boarding probability supplied from the unit 21, the temporary call is generated. The temporary call generation unit 25 supplies the generated temporary call to the communication unit 29.

According to the third embodiment described above, communication terminal 2 generates a call when the calculated boarding probability is greater than or equal to the boarding probability threshold P _MIN transmitted from wireless communication device 1. The group management device 3 records the calls registered in the past and calculates the threshold P _{MIN of the} boarding probability based on the past calls. That is, the threshold P _{MIN of} boarding probability is dynamically changed. Therefore, it is possible to use an appropriate threshold P _{MIN of the} boarding probability according to the tendency of the user in the building.

Fourth Embodiment
The fourth embodiment shows a configuration in which the time T _B from when the detection unit 21 detects the wireless communication device 1B to when the user arrives at the hall is determined by learning. The time T _B in the fourth embodiment is not a value determined based on the distance from the installation position of the wireless communication device 1B to the hall door of the elevator.

FIG. 18 is a functional block diagram of the elevator system according to the fourth embodiment.

As shown in FIG. 18, in the fourth embodiment, the communication terminal 2 includes a detection unit 21, a state acquisition unit 22, a recording unit 23, a boarding probability calculation unit 24, a temporary call generation unit 25, a main call generation unit 26, and learning. It has a unit 27, a notification unit 28, a communication unit 29, and a landing arrival detection unit 30.

The recording unit 23 holds, for example, a destination floor table 100, a detection recording table 101, a state recording table 102, a boarding probability threshold table 103, and a landing time table 106.

FIG. 19 is an example of a time table for moving to the hall in the fourth embodiment.

As shown in FIG. 19, the landing time table 106 includes the installation floor of the wireless communication device 1B detected immediately before the communication terminal 2 arrives at the landing, the detection date and time, the arrival date and time and the detection date and time and arrival date and time. Includes a set of time differences with. The unit of the time difference is seconds, for example.

The learning unit 27 determines the maximum travel time T _MAX and the threshold value D _{MAX of the} dissimilarity each time this call is generated, as in the first embodiment. In addition, the learning unit 27 determines the time T _B each time when the arrival at the hall is detected by the hall arrival detection unit 30 described later.

The method of determining the time T _B will be described below.

When the arrival at the hall is detected by the hall arrival detection unit 30, the installation floor of the wireless communication device 1B, the detection date and time, the arrival date and time at the hall and the detection date and time and arrival date and time detected immediately before the arrival at the hall. The set of the time difference between and is recorded in the time table 106 for moving to the hall. The arrival date and time at the hall is the date and time when the arrival at the hall is detected by the hall arrival detection unit 30. Learning unit 27 determines the average value of all the time difference recorded in the moving time table 106 to the landing as the time T _B. However, if there is no record in the moving time table 106 to the landing, the time T _B, the initial value is used which is recorded in advance in the memory 3b. The initial value is a positive number of appropriate size.

The time T _B may be held for each floor. In that case, the learning unit 27 does not calculate the average of all the time differences recorded in the landing time table 106, but calculates the average of the time differences for each of the same installation floors, so that each floor Determine the corresponding time T _B.

In the fourth embodiment, the state acquisition unit 22 continues to acquire the state of the communication terminal 2 even after detecting the wireless communication device 1B. The hall arrival detection unit 30 detects the arrival of the user at the hall based on the state acquired by the state acquisition unit 22 after the wireless communication device 1B is detected.

The landing arrival detection unit 30 periodically determines whether the communication terminal 2 is moving or stopped based on the state acquired by the state acquisition unit 22 using the value of the acceleration sensor, for example. The hall arrival detection unit 30 determines that the user has arrived at the hall when the communication terminal 2 is stopped for the first time after the wireless communication device 1B is detected. That is, the hall arrival detection unit 30 detects, for example, that the user has stopped in front of the hall door.

The hall arrival detection unit 30 may determine that the user has arrived at the hall when the state acquisition unit 22 detects the rise or fall of the communication terminal 2 based on the value of the atmospheric pressure sensor. According to this detection method, even when the user gets in the car without stopping in front of the hall door, it is possible to detect the arrival of the user at the hall. Further, the hall arrival detection unit 30 may detect the arrival of the user at the hall based on the position of the communication terminal 2 estimated using, for example, wireless communication, light, sound, or an image.

According to the fourth embodiment described above, communication terminal 2 detects the arrival of the housing at the hall, and based on the learning result, the communication terminals 2 from the wireless communication device 1B provided at the hall to the hall.
