Detailed Description

A mode for carrying out the present invention will be described with reference to the accompanying drawings. In the drawings, the same or corresponding portions are denoted by the same reference numerals. Duplicate descriptions are appropriately simplified or omitted.

Embodiment 1.

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

Fig. 1 is a schematic diagram showing an outline of an elevator system in embodiment 1. 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 control device 3, a control device 4, and a display device 5. The wireless communication device 1 is installed in, for example, a room or a doorway in a building, a landing of an elevator, 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 at, for example, a landing of an elevator. The group control device 3 is electrically connected to the control device 4 and the display device 5.

In fig. 1, a plurality of wireless communication apparatuses 1 are distinguished by attaching english alphabets to reference numerals. In fig. 1, a radio communication device 1A and a radio communication device 1B installed on the same floor are illustrated as a radio communication device 1. The wireless communication device 1A is provided in a passage in a building, for example. The wireless communication device 1B is installed in an elevator hall. The wireless communication device 1A is provided at a position distant from an elevator landing. The wireless communication apparatus 1A is disposed at a position at least where the communication range does not overlap with the wireless communication apparatus 1B.

The communication terminal 2 has a portable housing. The communication terminal 2 is held 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 control device 3, for example.

The communication terminal 2 has a "call generation section". The "call generation unit" generates a provisional call or a regular call upon communication with the wireless communication device 1. The communication terminal 2 transmits the generated call to the group control device 3. A provisional call is a call that can be cancelled until the assigned car reaches the landing. Formal calls are calls that cannot be cancelled until the assigned car reaches the landing.

The group control device 3 determines, for example, a car dispatch plan. The control device 4 controls the movement of the corresponding car in accordance with, for example, a dispatch plan. The display device 5 displays information indicating an assigned car corresponding to a call, for example.

As shown in fig. 2, the communication terminal 2 includes a detection section 21, a state acquisition section 22, a recording section 23, an elevator riding probability calculation section 24, a provisional call generation section 25, a main call generation section 26, a learning section 27, a notification section 28, and a communication section 29. The provisional call generation section 25 and the regular call generation section 26 are included in the "call generation section".

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 includes, for example, a processor 2a, a memory 2b, a communication device 2c, a sensor 2d, a display 2e, and a speaker 2 f.

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

The installation floor and installation location 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 expressed by an ID determined by "number of floors from the lowermost floor + 1", for example. The installation position of the wireless communication device 1 is expressed by, for example, an ID that can determine whether it is a landing or a position far from the landing. For example, the ID "1" indicates that the installation location is a landing. For example, the setting position is a position far from the landing expressed by ID "2".

The detection unit 21 is realized by, for example, the communication device 2 c. The detection unit 21 waits for communication from the wireless communication device 1. The detection unit 21 detects that the communication terminal 2 is within the communication range of the wireless communication device 1 when 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 exited outside the communication range of the wireless communication device 1 when a predetermined time has elapsed since the wireless communication device 1 no longer received information including the installation floor and the installation position.

The detection unit 21 detects that the communication terminal 2 is within the communication range of the wireless communication device 1 when it detects that the communication terminal has exited outside the communication range of the wireless communication device 1 and then receives information including the installation floor and the installation position from the wireless communication device 1 again.

Hereinafter, the case where it is detected that the communication terminal 2 enters the communication range of the wireless communication apparatus 1 is also simply expressed as "detecting the wireless communication apparatus 1".

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

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

The state of the communication terminal 2 is, for example, a moving state of a housing of the communication terminal 2. That is, the state acquiring unit 22 acquires the moving state of the user holding the communication terminal 2.

The state acquisition unit 22 starts acquisition of the state of the communication terminal 2 when detecting the wireless communication device 1A installed at a position distant from the hall. The state acquisition unit 22 ends acquisition of the state of the communication terminal 2, for example, when detecting the wireless communication device 1B installed in the hall. The state acquisition unit 22 may acquire the state of the communication terminal 2 after the maximum travel time T has elapsed_MAXWhen this occurs, the acquisition of the state of the communication terminal 2 is terminated. For example, the state acquisition unit 22 detects the wireless communication device 1B installed in the hall, or the maximum travel time T has elapsed from the start of acquisition of the state of the communication terminal 2_MAXThe state of the communication terminal 2 is continuously acquired at regular intervals.

Maximum travel time T_MAXFor example, it is necessary for the user to move from the communication range of the wireless communication device 1A to the communication range of the wireless communication device 1BIs measured. Maximum travel time T_MAXFor example, determined by the learning unit 27.

Hereinafter, the state acquired at the t-th time from the start of the acquisition of the state of the communication terminal 2 by the state acquisition unit 22 will be referred to as "x"_t. State x_tFor example as the orientation d of the communication terminal 2_tAnd velocity v_tGroup (b) with x_t＝(d_t，v_t) To indicate. Orientation d_tFor example, an angle with a certain orientation as a reference. For example, in the case of north as a reference, 90 degrees clockwise represents "east", 180 degrees clockwise represents "south", and 270 degrees clockwise represents "west". Velocity v_tThe unit of (b) is, for example, m/s. In addition, state x_tExcept for containing the orientation d_tAnd velocity v_tIn addition, the relative distance moved by the communication terminal 2 from the start of acquiring the state by the state acquiring unit 22 may be included.

The state acquisition unit 22 sets the state x every time the state acquisition is completed_tThe date and time of detection of the wireless communication device 1A and the installation floor of the wireless communication device 1A are recorded in the state log table 102. That is, the state acquisition unit 22 detects the date and time, the installation floor, and the state x every time the acquisition of the state of the communication terminal 2 is completed_tAnd recording the data in association.

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

Fig. 4 is an example of a destination floor table in embodiment 1.

As shown in fig. 4, the destination floor table 100 includes a group of a departure floor and a destination floor of a user having the communication terminal 2. The contents of the destination floor table 100 are recorded in advance in the communication terminal 2, 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 embodiment 1.

As shown in fig. 5, the detection log table 101 includes a set of the detected date and time, the detected installation floor of the wireless communication device 1, and the 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 ID "1". For example, in the detection record of the wireless communication apparatus 1B, the installation position is represented by ID "2".

Fig. 6 is an example of a status record table in embodiment 1.

As shown in fig. 6, the state log table 102 includes the date and time of detection of the wireless communication device 1A, the installation floor of the wireless communication device 1A, and the state sequence { x ] acquired by the state acquiring unit 22_tThe group of (1 b), wherein the detection of the radio communication apparatus 1A becomes a trigger for acquisition of the start state. Sequence of states { x_tIndicates how the user holding the communication terminal 2 moves, for example.

For example, a sequence including 4 states is recorded in the top row 1 of the state recording table 102 shown in fig. 6. The 1 st acquired state in the sequence is x₁(180, 0.5). The 2 nd state taken in the sequence is x₂(180, 0.5). The 3 rd state taken in the sequence is x₃(90, 0.5). The 4 th acquired state in the sequence is x₄＝(90，0)。

As shown in fig. 7, the boarding probability threshold value table 103 includes time slots, floors, and threshold values P of boarding probabilities_MINThe group (2). The entry of the floor in the boarding probability threshold value table 103 represents a departure floor. Threshold value P_MINAre used for generating temporary calls. Threshold value P_MINThe unit of (b) is, for example, a percentage. The contents of the boarding probability threshold value table 103 are recorded in the communication terminal 2, for example, in advance. The contents of the boarding probability threshold value table 103 are common regardless of the communication terminal 2, for example.

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

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

First, the boarding probability calculation unit 24 calculates the degree of difference between the latest state sequence acquired by the state acquisition unit 22 and the past state sequence recorded in the state record table 102. At this point in time, the latest state sequence has not yet been recorded into the state record table 102. The degree of difference is defined by the following formula (1).

[ formula 1]

The latest state sequence is used { x }_t}(1≤t≤T_LAST) To indicate. x is the number of_tBy x_t＝(d_t，v_t) To indicate. T is_LASTIndicates the number of states included in the latest state sequence. For example, in the case where the latest state sequence is { (175, 0.5), (185, 0.5), (180, 0.5), (95, 0.5), (85, 0) }, T _LAST5. I.e. x_t(t＝T_LAST) Is the latest state among the states acquired by the state acquisition unit 22.

Past State sequences are { x'_t}(1≦t≦T'_MAX) To indicate. x'_tFrom x'_t＝(d'_t，v'_t) To indicate. T'_MAXIndicates the number of states included in each sequence recorded in the state recording table 102. For example, in the case of the sequence recorded in the top 1 st line of the status record table 102 shown in FIG. 6, T'_MAX4. Namely, x'_t(t＝T'_MAX) The state is the last state obtained from the past states included in the sequence of a certain detection date and time.

The outermost bracketed part of the expression (1) is the root mean square of the difference between the latest state acquired by the state acquiring unit 22 and the state recorded in the state recording table 102. The expression (1) means the minimum value among the values in parentheses calculated by changing the conditions. The degree of difference is the minimum value among the values in parentheses calculated for all combinations of L and k.

Formula (A), (B) and1) l in (2) represents the number of states compared between the latest state sequence and the past state sequence. L is 2. ltoreq. L. ltoreq.min (T)_LAST，T'_MAX) Is an integer of (1).

K in the expression (1) is a number indicating which L states among a plurality of states included in the past state sequence are to be compared. Specifically, the (k-2) +1 th to k-th states among the plurality of states included in a certain sequence are used. k is L-k-T'_MAXIs an integer of (1).

Hereinafter, a specific example of the calculation of the degree of difference based on the formula (1) will be described. In this specific example, a case of calculating the degree of difference from the state sequence recorded in the 1 st row from the top of the state recording table 102 shown in fig. 6 will be described.

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 _LAST5. To this, T'_MAX＝4。

First, L is determined to calculate the degree of difference from two state sequences having different numbers of states. According to L is more than or equal to 2 and less than or equal to min (T)_LAST，T'_MAX) And L is any one of 2, 3 or 4. Hereinafter, a case where L is 2 will be described.

The L states are used for the calculation in order from new to old, based on the latest state sequence. In the case where L is 2, will { (d)_TLAST-1，v_TLAST-1)，(d_TLAST，v_TLAST) { (95, 0.5), (85, 0) } is used for the calculation of the difference degree.

Next, it is determined which two states are used among the states included in the state sequence in the top row 1 of the state record table 102. K is more than or equal to L and less than or equal to T'_MAXAnd k is any one of 2, 3 or 4.

For example, when k is 2, the 1 st and 2 nd states among the states included in the state sequence in the 1 st row from the top of the state recording table 102 are used. Namely, mixing { (d'₁，v'₁)，(d'₂，v'₂) { (180, 0.5), (180, 0.5) } is used for the calculation of the difference degree.

For example, when k is 3, the 2 nd and 3 rd states among the states included in the state sequence in the 1 st row from the top of the state recording table 102 are used. Namely, mixing { (d'₂，v'₂)，(d'₃，v'₃) { (180, 0.5), (90, 0.5) } is used for the calculation of the difference degree.

For example, when k is 4, the 3 rd and 4 th states among the states included in the state sequence in the 1 st row from the top of the state recording table 102 are used. Namely, mixing { (d'₃，v'₃)，(d'₄，v'₄) { (90, 0.5), (90, 0) } is used for calculation of the difference degree.

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

The boarding probability calculation unit 24 extracts, from the state record table 102, the installation floor that is the same as the installation floor of the wireless communication device 1A detected this time and whose degree of difference is the threshold value D_MAXThe following detection date and time. The number of extracted date and time of detection is represented by N_ATo indicate. D_MAXFor example, determined by the learning unit 27. In addition, when the date and time of detection is extracted, a time period or a day of the week may be defined. For example, when the user's action changes depending on the time period, such as when the elevator is likely to be used at work and during work, and when the elevator is likely to be used at leisure, the probability of boarding can be calculated more accurately by limiting the extraction target to the detection date and time of the same time period or the same day of the week.

The boarding probability calculation unit 24 extracts the detection log recorded in the detection log table 101, the installation floor is the same as the installation floor of the wireless communication device 1A detected this time, the installation position is the landing, and the maximum travel time T has elapsed from the extracted detection date and time_MAXThe period of time (c) is recorded. The number of extracted detection records is N_BTo indicate. The boarding probability calculation unit 24 calculates N_B/N_AThe value of x 100 is calculated as the riding probability. The unit of the boarding probability is, for example, a percentage.

The temporary call generation section 25 is realized, for example, by the processor 2a executing a program recorded in the memory 2 b. The provisional call generation unit 25 performs the following operations each time the boarding probability calculation unit 24 calculates the boarding probability. The provisional call generation unit 25 acquires a threshold value P of boarding probability corresponding to the current date and time from the boarding probability threshold value table 103_MIN. After the detection of the wireless communication device 1A as a trigger for calculating the boarding probability, no provisional call is generated and the boarding probability calculated by the boarding probability calculation section 24 is at the threshold P_MINIn the above case, the provisional call generation unit 25 generates a provisional call. The provisional call generation section 25 supplies the generated provisional call to the communication section 29. The temporary call includes information such as a terminal ID capable of identifying the communication terminal 2, a departure floor, a destination floor, and arrival time at a hall. The departure floor is the installation floor of the wireless communication device 1A. The destination floor is the floor associated with the departure floor in the destination floor table 100. The arrival time at the hall included in the provisional call is the sum of the detection date and time of the wireless communication device 1A and the time T_AAnd the resulting sum minus the current time of day. Time T_AIs the time from when the detection section 21 detects the wireless communication device 1A until the user arrives at the landing.

For time T_AThe calculation method of (2) will be explained.

The temporary call generation unit 25 generates a movement schedule 104 between the wireless communication devices from the detection record table 101. The movement schedule 104 shows the movement time between the wireless communication apparatuses 1. As shown in fig. 8, the movement schedule 104 includes a set of the detection date and time of the wireless communication apparatus 1A, the detection date and time of the wireless communication apparatus 1B, and the time difference. The travel schedule 104 detects the maximum travel time T of the wireless communication device 1A installed on the departure floor from the detection unit 21_MAXThe internal detection unit 21 detects the wireless communication device 1B installed on the departure floor, and records each detection date and time. The time difference in the movement schedule 104 is the difference between the detected date and time of the wireless communication apparatus 1A and the detected date and time of the wireless communication apparatus 1B. Unit example of time differenceSuch as seconds.

Will time T_AAs an average value of the time differences recorded in the movement schedule 104 and a preset time T_BThe sum of (a) and (b) is calculated. Time T_BIs the time from when the detection section 21 detects the wireless communication device 1B until the user arrives at the landing. Time T_BFor example, a value uniquely determined according to the distance from the installation position of the wireless communication device 1B to the landing door of the elevator. Time T_BFor example, the distance from the installation position of the wireless communication device 1B to the landing door is divided by the moving speed of a normal person. Time T in the case where there are a plurality of landing doors_BFor example, the length is determined based on an average value of the lengths of the paths from the installation position of the wireless communication device 1B to the landing doors. In addition, when the travel schedule 104 is empty, the maximum travel time T is used_MAXAs time T_A。

The regular call generation unit 26 is realized by the processor 2a executing a program recorded in the memory 2b, for example. The actual call generation unit 26 generates an actual call when the detection unit 21 detects the wireless communication device 1B installed in the hall. The regular call generation section 26 supplies the generated regular call to the communication section 29. The actual call includes information such as the ID of the communication terminal 2, the departure floor, the destination floor, and the arrival time at the hall. The departure floor is the installation floor of the wireless communication device 1B. The destination floor is the floor associated with the departure floor in the destination floor table 100. The time to reach the landing included in the regular call is set as time T_B. In order to prevent the wireless communication device 1B, which detects the destination floor by the detection section 21, from generating a regular call when the user gets off the elevator car at the destination floor, the regular call generation section 26 does not generate a regular call for a predetermined period of time after the regular call is generated.

The learning unit 27 is realized by the processor 2a executing a program recorded in the memory 2b, for example. The learning unit 27 determines the maximum travel time T each time a regular call is generated_MAXAnd a threshold value D of the degree of difference_MAX. That is, the learning unit 27 updates the maximum travel time T based on the learning result_MAXAnd a threshold value D_MAX. However, the initial value recorded in advance in the memory 2b is used as the maximum travel time T until the main call is first generated_MAXAnd a threshold value D of the degree of difference_MAX. The initial value is a positive number of appropriate size.

In the learning unit 27, the time K × T elapses after the wireless communication device 1A is detected_MAXIf the wireless communication devices 1B of the same installation floor are detected up to this point, the difference t between the detected dates and times_DIFFGreater than the current T_MAXThen set T_MAX＝t_DIFF. K is a natural number of appropriate size. In addition, if t_DIFFAt the current T_MAXThen, the learning unit 27 does not update T_MAX。

In the learning unit 27, if the degree of difference D calculated by the equation (1) is larger than the current D when the acquisition of the state of the communication terminal 2 is continued until the wireless communication device 1B is detected_MAXThen set D_MAXD. In addition, if the difference D is at the current D_MAXThe learning unit 27 does not update D in the following_MAX。

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

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

As shown in fig. 2, the group control device 3 includes a communication unit 31, a call registration unit 32, and a dispatch plan management unit 33.

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

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

The communication unit 31 is realized by the wireless device 3c, for example. The communication unit 31 performs wireless communication by a communication method such as Wi-Fi (registered trademark) or Bluetooth (registered trademark). The communication unit 31 receives a provisional call or a regular 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 3 b. The call registration unit 32 calculates the arrival time at the landing corresponding to the provisional call or the actual call by adding the current date and time to the arrival time at the landing included in the provisional call or the actual call. The call registration section 32 determines an assigned car for a new call based on the departure floor, the destination floor, the arrival time at the landing, and a dispatch plan 110 described later. The call registration unit 32 determines a car having the smallest waiting time for the provisional call and the actual call for which the assigned car has already been determined as the assigned car for the new call. The waiting time for a call is a time from when the communication terminal 2 arrives at a hall of the starting floor to when the assigned car corresponding to the call arrives at the starting floor. The call registration section 32 provides the dispatch plan management section 33 with the type of call, terminal ID, departure floor, destination floor, arrival time at the landing, and the group of assigned cars. The type of call is information indicating which one of a provisional call and a regular call is.

The dispatch plan manager 33 is realized by the processor 3a executing a program recorded in the memory 3b, for example. The dispatch plan manager 33 stores information on the provisional calls and the actual calls assigned to the cars in the memory 3b as a dispatch plan 110. That is, dispatch plan 110 is generated for each car.

Fig. 10 shows an example of dispatch plan in embodiment 1.

Fig. 10 illustrates a dispatch plan 110 for a car. As shown in fig. 10, the dispatch plan 110 includes the type of call, the terminal ID of the communication terminal 2, the departure floor, the destination floor, and the arrival time to the hall calculated by the call registration section 32.

When a group of the type of call, terminal ID, departure floor, destination floor, arrival time at a landing, and assigned car is provided from the call registration section 32, the dispatch plan management section 33 adds information included in the group to the dispatch plan 110 for the assigned car. However, when a regular call of the same terminal ID is already registered in the dispatch plan 110 for an arbitrary car, the dispatch plan managing section 33 does not add information included in the group to the dispatch plan 110 for the assigned car. When a provisional call of the same terminal ID is already registered in the dispatch plan 110 for an arbitrary car, the dispatch plan managing section 33 deletes the provisional call and adds information included in the group to the dispatch plan 110 for the assigned car.

As described later, when the current floor and the moving direction of the car are provided from the control device 4, the dispatch plan management unit 33 deletes, from the dispatch plan 110 for the car, a regular call whose stop floor of the car is the departure floor or the destination floor and whose arrival time at the arrival hall has been exceeded at the current time. Further, the dispatch plan management unit 33 deletes a provisional call that has exceeded the arrival time at the landing at the current time from the dispatch plans 110 for all cars. The dispatch plan manager 33 supplies the dispatch plan 110 updated as described above to the control device 4.

The control device 4 refers to the dispatch plan 110 for the corresponding car supplied from the group control device 3. The control device 4 stops the car at the departure floor to which the provisional call and the actual call of the car are assigned until the arrival time at the hall based on the dispatch plan 110 for the corresponding car. 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 among arrival times at landings. The control device 4 stops the car for a predetermined time after the car reaches the destination floor of the actual call. When the car arrives at a certain floor or when the car departs from a certain floor, the control device 4 supplies the current floor and the moving direction of the car to the group control device 3.

The display device 5 displays the assigned car of the actual call determined by the group control device 3 on the screen to notify the user.

Fig. 11 is a sequence diagram showing an example of operation of the elevator system according to embodiment 1. The following describes the operation flow of the entire system when the user having the communication terminal 2 arrives at an elevator hall through a doorway, with reference to fig. 11. In addition, the wireless communication apparatus 1A is provided in the tunnel.

When the user enters the communication range of the wireless communication device 1A provided in the tunnel, the detection section 21 of the communication terminal 2 detects the wireless communication device 1A (step S1). The communication terminal 2 calculates the boarding probability by the boarding probability calculation unit 24 each time the state acquisition unit 22 acquires the state of the communication terminal 2. If the probability of taking the elevator is at the threshold value P_MINAs described above, the communication terminal 2 generates a provisional call by the provisional call generation section 25 (step S2). The communication terminal 2 sends a provisional call to the group management device 3 by using the communication unit 29 (step S3).

When the communication unit 31 receives a provisional call from the communication terminal 2, the group control device 3 determines an assigned car using the call registration unit 32 (step S4). The group control device 3 updates the dispatch plan 110 by the dispatch plan manager 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 regular call by the regular call generating unit 26 (step S6). The communication terminal 2 sends a regular call to the group management device 3 by using the communication unit 29 (step S7). The communication terminal 2 determines the maximum travel time T by the learning unit 27_MAXAnd a threshold value D of the degree of difference_MAX(step S8)

When the communication unit 31 receives the actual call from the communication terminal 2, the group control device 3 determines an assigned car using the call registration unit 32 (step S9). The group control device 3 updates the dispatch plan 110 by the dispatch plan manager 33. The group control device 3 displays the assigned car on the display device 5 (step S10). The group control 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 in embodiment 1. The operation of the communication terminal 2 that has generated the provisional call from the detection of the wireless communication device 1A will be described in detail below with reference to fig. 12.

When the wireless communication device 1A is detected by the detection unit 21, the communication terminal 2 records the detected date and time, the detected installation floor of the wireless communication device 1A, and the detected installation position in the detection log table 101 (step S21). The communication terminal 2 periodically acquires the state by the state acquisition unit 22 (step S22). The communication terminal 2 calculates the boarding probability using the acquired state (step S23). The communication terminal 2 judges whether or not a temporary call has not been generated from the detection of the wireless communication device 1A as a trigger for calculating the boarding probability and the boarding probability is at the threshold P_MINThis is done (step S24).

If the condition of step S24 is satisfied, the communication terminal 2 generates a provisional 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 S25 is not performed and the process of step S26 is performed.

In step S26, it is determined whether or not the maximum travel time T has elapsed since the acquisition_MAX. When it is determined in step S26 that the maximum travel time T has not elapsed since the acquisition state was acquired_MAXIn the case of (3), the process of step S27 is performed. In step S27, the detection unit 21 determines whether or not the wireless communication device 1B is detected. If it is determined in step S27 that the wireless communication device 1B has been detected, the communication terminal 2 ends the acquisition of the state and records the state sequence acquired so far in the state record table 102 (step S28).

When in step S26, it is determined that the maximum travel time T has elapsed from the acquisition state_MAXIn the case of (3), the process of step S28 is performed. If it is determined in step S27 that the wireless communication device 1B has not been detected, the process proceeds to step S22.

According to embodiment 1 described above, the communication terminal 2 has a portable housing, acquires the movement state of the housing, and calculates the elevator riding probability of the elevator based on the movement state of the housing. In other words, the riding probability can be calculated with high accuracy by taking the moving state of the user into consideration. The communication terminal 2 determines whether or not a call is generated based on the calculated boarding probability, and transmits the generated call to the group control device 3 by wireless communication. The group control device 3 receives a call generated based on the probability of riding an elevator calculated by the communication terminal 2 having a portable housing from the state of the housing, determines an assigned car for the call, and updates a dispatch plan of the car. Therefore, call registration can be performed at a place far from the hall, and the occurrence of useless calls can be suppressed. As a result, the operation efficiency of the elevator can be improved.

Further, according to embodiment 1, the movement state of the casing includes at least one of acceleration, speed, orientation, and movement distance from the start of acquiring the movement state. Therefore, the elevator riding probability can be calculated with higher accuracy.

Further, according to embodiment 1, the communication terminal 2 sets the calculated boarding probability to a preset threshold value P_MINIn the above case and in the case where the wireless communication device 1B installed in the elevator hall is detected, a call is generated. Therefore, the occurrence of useless calls can be suppressed.

Further, according to embodiment 1, when detecting the wireless communication device 1A installed at a place other than an elevator hall in the building, the communication terminal 2 starts acquiring the moving state of the casing. Then, the communication terminal 2 detects the wireless communication device 1B installed in the elevator hall, or the maximum moving time T between the wireless communication devices 1 after the start of acquiring the moving state of the casing and the elapse of the time_MAXUntil then, the movement state of the housing is continuously acquired periodically. Therefore, the state is acquired only for a necessary period, and thus, the processing load of the communication terminal 2 can be prevented from increasing.

Further, according to embodiment 1, the communication terminal 2 updates the maximum travel time T based on the learning result_MAX. Therefore, the period during which the movement state of the casing is continuously obtained can be set more appropriately.

Further, according to embodiment 1, the communication terminal 2 records the moving state of the housing acquired in the past. The communication terminal 2 calculates the boarding probability based on the number of times of detection of the wireless communication device 1A installed at a place other than a hall, which becomes a trigger for acquiring a moving state in which the degree of difference from the nearest moving state among the past moving states of the casing is equal to or less than a threshold value, and the number of times of past detection of the wireless communication device 1B installed at a hall. Therefore, the elevator riding probability can be calculated with high accuracy.

Further, according to embodiment 1, the communication terminal 2 updates the threshold D of the degree of difference according to the learning result_MAX. Therefore, the elevator riding probability can be calculated with higher accuracy.

Further, according to embodiment 1, the communication terminal 2 calculates the elevator riding probability each time the moving state of the casing is acquired. Therefore, the occurrence of useless calls can be suppressed.

Further, according to embodiment 1, the communication terminal 2 calculates a moving time to a hall from the current date and time, the detected date and time of the wireless communication device 1, and a moving time from the wireless communication device 1 to the hall recorded in advance, and generates a call including information indicating the moving time to the hall. The group control device 3 calculates the arrival time of the casing at the hall based on the current date and time and information indicating the movement time to the hall included in the call received from the communication terminal 2, and includes the arrival time at the hall in the dispatch plan 110. Therefore, the operation efficiency of the elevator can be improved.

Further, according to embodiment 1, the group control device 3 deletes a call that has exceeded the arrival time at the arrival hall at the present time from the dispatch plan 110. Therefore, the operation efficiency of the elevator can be improved.

Further, according to embodiment 1, the communication terminal 2 calculates the moving time from the wireless communication device 1A installed at a place other than a hall to the hall based on the time difference between the detected date and time of the wireless communication device 1A installed at the place other than the hall and the detected date and time of the wireless communication device 1B installed at the hall. Therefore, the operation efficiency of the elevator can be improved.

Embodiment 2.

Embodiment 2 shows that the time T is calculated from the distance between the wireless communication apparatus 1 and the hall_AAnd a maximum moving time T_MAXThe structure of (1).

The functional block diagram of the elevator system in embodiment 2 is the same as that in fig. 2.

In embodiment 2, 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 distance from the wireless communication device 1 to the hall. Instead of transmitting the distance to the hall by the wireless communication device 1 itself, another device may be provided that transmits the distances from all the wireless communication devices 1 in the building to the hall at once to the communication terminal 2.

When detecting the wireless communication device 1, the detection unit 21 records a group 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 log table 101. When detecting the wireless communication device 1, the detection unit 21 records 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 in a distance table 105 described later.

The distance from the wireless communication device 1 to the landing is, for example, the length of a path from the installation position of the wireless communication device 1 to a landing door of the elevator. The distance from the wireless communication device 1A to the landing is, for example, the length of a path from the installation position of the wireless communication device 1A to a landing door. The distance from the wireless communication device 1B to the landing is, for example, the length of a path from the installation position of the wireless communication device 1B to a landing door. When there are a plurality of landing doors, for example, the average of the lengths of the paths from the installation position of the wireless communication device 1 to the respective landing doors may be 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 record table 101, a state record table 102, a boarding probability threshold table 103, and a distance table 105.

Fig. 13 is an example of the distance table in embodiment 2.

As shown in fig. 13, the distance table 105 includes a set of installation floors of the wireless communication devices 1, installation positions of the wireless communication devices 1, and distances from the wireless communication devices 1 to landings. For example, the installation location of the wireless communication device 1A is represented by ID "1". For example, the installation location of the wireless communication device 1B is represented by ID "2". The distance from the landing is in units of meters, for example.

For time T in embodiment 2_AThe calculation method of (2) will be explained. The temporary call generation unit 25 extracts a sequence of states acquired on the installation floor included in the information transmitted from the wireless communication device 1A from the state record table 102. The provisional call generation unit 25 calculates an average value of the velocities included in the states in the extracted sequence. The provisional call generation unit 25 divides the distance from the wireless communication device 1A to the hall by the average value of the speeds to obtain a value as the time T_ATo perform the calculation. However, if the sequence of the states acquired at the installation floor does not exist, the time T from the detection of the wireless communication device 1A to the arrival at the landing is_AIs related to the maximum moving time T_MAXThe same value.

For the maximum moving time T in embodiment 2_MAXThe calculation method of (2) will be explained. The learning unit 27 calculates a difference between the distance from the wireless communication device 1A to the landing and the distance from the wireless communication device 1B to the landing, in the installation floor of the wireless communication device 1B detected by the detection unit 21, based on the distance table 105. The learning unit 27 extracts the shape obtained on the installation floor of the wireless communication device 1BA sequence of states. The learning unit 27 extracts the lowest value of the speed included in the state in the extracted sequence. Wherein the lowest value of the speed is set to a value greater than 0. The learning unit 27 divides the difference between the distances by the minimum value of the speed to obtain a value as the maximum travel time T_MAXTo perform the calculation.

According to embodiment 2 described above, the communication terminal 2 calculates the maximum travel time T from the distance from the wireless communication device 1 to the hall_MAX. 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 can be calculated with high accuracy_MAX。

Further, according to embodiment 2, the communication terminal 2 calculates the moving time from the wireless communication device 1A installed at a place other than a hall to the hall based on the distance from the 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 time T can be calculated with high accuracy_A。

Embodiment 3.

In embodiment 3, threshold P showing elevator boarding probability of each floor is shown_MINThe group control device 3 calculates the data and transmits the data to the communication terminal 2 via the wireless communication device 1.

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

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

Fig. 15 shows an example of a call performance table according to embodiment 3.

As shown in fig. 15, the call performance table 111 includes a set of terminal ID, departure floor, destination floor, temporary call reception time, and regular call reception time.

When both the temporary call reception time and the regular call reception time exist as in the case where the terminal ID is the performance 0001, this indicates that the group control device 3 has received both the temporary call and the regular call from the terminal.

When the reception time of the temporary call is present and the reception time of the actual call is blank as in the case where the terminal ID is the performance 0002, it indicates that the group control device 3 has received the temporary call from the terminal and has not received the actual call. At the present time, the arrival time at the hall corresponding to the provisional call has not yet been exceeded.

When the reception time of the temporary call is "x" and there is an actual call reception time as in the case where the terminal ID is performance 0003, it indicates that the group control device 3 has not received the temporary call from the terminal and has received only the actual call.

When the reception time of the provisional call is "x" and the reception time of the actual call is "x" as in the case where the terminal ID is performance 0004, it indicates that the group control device 3 has received the provisional call from the terminal, but has not received the actual call even if the arrival time to the hall is exceeded. That is, in this case, it indicates that the provisional call has been deleted from the dispatch plan 110.

The dispatch plan management unit 33 updates the call performance table 111 of the call recording unit 34 every time the dispatch plan 110 is updated.

When a provisional call is added to the dispatch plan 110, the dispatch plan management unit 33 newly adds a group of the terminal ID, the departure floor, the destination floor, the provisional call reception time, and the actual call reception time to the call performance table 111. At this time, the temporary call receiving time is the current date and time, and the regular call receiving time is blank.

When an actual call is added to the dispatch plan 110, the dispatch plan manager 33 checks whether or not a group having the same terminal ID, departure floor, and destination floor and a blank actual call reception time is present in the call performance table 111. If the group exists, the dispatch plan manager 33 records the current date and time at the time of the vacant official call reception. If there is no such group, the dispatch plan manager 33 newly adds a group of the terminal ID, the departure floor, the destination floor, the temporary call reception time, and the actual call reception time to the call performance table 111. At this time, the temporary call reception time is "x", and the regular call reception time is the current date and time.

When a provisional call that exceeds the arrival time at the arrival hall is deleted from the dispatch plan 110 at the present time, the dispatch plan management unit 33 selects a group from the call performance table 111 in which the terminal ID, the departure floor, and the destination floor are the same and the regular call reception time is blank. The dispatch plan manager 33 records "x" at the time of receipt of the official call for the group.

The threshold calculation unit 35 is realized by the processor 3a executing a program recorded in the memory 3b, for example. The threshold value calculation unit 35 calculates the threshold value P of the boarding probability_MINIs recorded in advance in the memory 3 b. Candidate P is for example a value on the 10% scale from 10% to 100%. The threshold value calculation unit 35 evaluates the average waiting time for each candidate P. The threshold value calculation unit 35 sets the candidate P having the smallest average waiting time as the threshold value P of the boarding probability_MINProvided to the wireless communication apparatus 1.

As shown in fig. 16, the threshold value calculating section 35 includes a virtual call generating section 351, a simulation section 352, and a threshold value determining section 353.

The virtual call generation unit 351 generates virtual call information necessary for the evaluation of the waiting time from the call performance table 111. The virtual call information includes the type of call, the departure floor, the destination floor, and the group of times when the call occurred. The virtual call generation unit 351 will be described in detail below.

First, the virtual call generation section 351 calculates, from the call performance table 111, the number of occurrences of each day of a temporary call in which the temporary call reception time is a period from the same time as the current time until a predetermined time has elapsed and there is an actual call reception time or the actual call reception time is "x". Similarly, the virtual call generation section 351 calculates, from the call performance table 111, the number of occurrences of an actual call, which has an actual call reception time within a period from the same time as the current time until a predetermined time has elapsed, and which has a temporary call reception time or a temporary call reception time of "x" for each day. The number of such temporary calls or regular calls to be generated is calculated for each group of the departure floor and the destination floor.

Fig. 17 is another example of the call performance table according to embodiment 3. A specific example of the number of calls generated calculated from the call performance table 111 will be described with reference to fig. 17. In this specific example, let 08 for current date and time 2016/12/09: 21: 00. the predetermined time is set to 10 minutes. In this case, the temporary call reception time is from 08: 21: the number of temporary calls that are present until 10 minutes elapses after 00 and that have an actual call reception time or an actual call reception time of "x" is 3. Further, the regular call reception time is from 08: 21: the number of regular calls that are present until 10 minutes elapses from 00 and have a temporary call reception time or a temporary call reception time of "x" is 3.

The virtual call generation unit 351 generates a sequence of virtual calls and virtual regular calls so as to satisfy the above-described number of occurrences for each of the groups of the departure floor and the destination floor. In this case, a random time from the same time as the current time until a predetermined time elapses is set as the call occurrence time.

The simulation unit 352 assumes a certain candidate P as the threshold P_MINUnder the condition (2), an assigned car for a sequence of a virtual provisional call and a virtual regular call generated by the virtual call generation unit 351 is determined. At this time, the virtual temporary call is randomly deleted with the probability of the candidate P. The assigned car is not determined for the virtual temporary call that was deleted. The simulation unit 352 calculates the average waiting time of the actual call when the assigned car is operated.

Threshold valueThe determination unit 353 determines the candidate P having the smallest average waiting time calculated by the simulation unit 352 as the threshold P of the elevator-taking probability_MIN。

The wireless communication device 1 periodically transmits a threshold value P including an installation floor of the wireless communication device 1, an installation position of the wireless communication device 1, and an elevator boarding probability to a communication terminal 2 existing in a communication range_MINThe information of (1).

When detecting the wireless communication device 1, the detection unit 21 records a group 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 log table 101. Further, the detection unit 21 sets the threshold P of the boarding probability received from the radio communication device 1_MINAnd supplied to the temporary call generation section 25.

The temporary call is not generated from the detection of the wireless communication device 1A as a trigger for calculating the boarding probability, and the boarding probability calculated by the boarding probability calculation unit 24 is at the threshold value P of the boarding probability supplied from the detection unit 21_MINIn the above case, the provisional call generation unit 25 generates a provisional call. The provisional call generation section 25 supplies the generated provisional call to the communication section 29.

According to embodiment 3 described above, the communication terminal 2 calculates the boarding probability as the threshold P of the boarding probability transmitted from the wireless communication device 1_MINIn the above case, a call is generated. The group control device 3 records calls registered in the past, and calculates a threshold value P of the boarding probability from the calls registered in the past_MIN. I.e. threshold value P of the probability of riding the elevator_MINIs dynamically changed. Therefore, the threshold P of the appropriate boarding probability can be used according to the tendency of the user in the building_MIN。

Embodiment 4.

Embodiment 4 shows that the time T from the detection of the wireless communication device 1B by the detection section 21 to the arrival of the user at the hall is determined by learning_BThe structure of (1). Time T in embodiment 4_BNot a value determined according to the distance from the installation position of the wireless communication device 1B to the landing door of the elevator.

As shown in fig. 18, in embodiment 4, the communication terminal 2 includes a detection section 21, a state acquisition section 22, a recording section 23, an boarding probability calculation section 24, a provisional call generation section 25, a main call generation section 26, a learning section 27, a notification section 28, a communication section 29, and a landing arrival detection section 30.

The recording unit 23 holds, for example, a destination floor table 100, a detection record table 101, a state record table 102, an elevator riding probability threshold table 103, and a movement schedule table 106 for moving to a landing.

Fig. 19 is an example of a schedule of moving to a landing in embodiment 4.

As shown in fig. 19, the travel schedule 106 for traveling to the hall includes a set of the installation floor of the wireless communication device 1B detected immediately before the communication terminal 2 arrives at the hall, the detected date and time, the arrival date and time at the hall, and the time difference between the detected date and time and the arrival date and time. The unit of the time difference is, for example, seconds.

As in embodiment 1, the learning unit 27 determines the maximum travel time T each time a regular call is generated_MAXAnd a threshold value D of the degree of difference_MAX. The learning section 27 determines the time T each time the landing arrival detection section 30, which will be described later, detects the arrival of the user at the landing_B。

For time T_BThe method of determining (2) will be described.

When the arrival of the user at the hall is detected by the hall arrival detection section 30, a set of the installation floor of the wireless communication device 1B detected immediately before the arrival at the hall, the detected date and time, the arrival date and time at the hall, and the time difference between the detected date and time and the arrival date and time is recorded in the travel time table 106 for traveling to the hall. The arrival date and time at the landing is the date and time detected by the landing arrival detection section 30. The learning unit 27 determines the average value of all the time differences recorded in the moving schedule 106 for moving to the hall as the time T_B. However, when the moving schedule 106 for moving to the hall is not recorded, the moving schedule is used in advanceThe initial value recorded in the memory 3b is taken as the time T_B. The initial value is a positive number of appropriate size.

In addition, the time T may be maintained for different floors_B. In this case, the learning unit 27 determines the time T corresponding to each floor by calculating the average value of the time differences for the same installation floor, without calculating the average value of all the time differences recorded in the travel schedule 106 for traveling to the hall_B。

In embodiment 4, the state acquisition unit 22 continues to acquire the state of the communication terminal 2 even after detecting the wireless communication device 1B. The landing arrival detection section 30 detects that the user has arrived at the landing based on the state acquired by the state acquisition section 22 after the wireless communication device 1B has been detected.

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

The landing arrival detection section 30 may determine that the user has arrived at the landing, for example, when the state acquisition section 22 detects the rise or fall of the communication terminal 2 based on the value of the air pressure sensor. According to this detection method, even when the user rides the car without stopping in front of the landing door, it is possible to detect that the user has arrived at the landing. The landing arrival detection section 30 may detect that the user has arrived at the landing, for example, from the position of the communication terminal 2 estimated using wireless communication, light, sound, images, or the like.

According to embodiment 4 described above, each time the communication terminal 2 detects that the casing has reached the hall, the communication terminal calculates the moving time from the wireless communication device 1B installed in the hall to the hall based on the learning result. Therefore, even when the installation position of the wireless communication device 1B differs depending on the floor, the time T can be calculated with high accuracy_B。

Industrial applicability
