  The control system of the elevator according to the present embodiment detects congestion in each car 13 (13a, 13b, 13c...). The detection of the congestion state in the car 13 is detected, for example, by at least one of the car imaging device 47 and the load detection device 48 provided in the car 13.

  The detection of congestion in the car 13 by the car imaging device 47 uses image recognition technology by the car imaging device 47 provided on a ceiling or the like as shown in FIG. 4. The cage imaging device 47 is a camera or the like, and recognizes the number of passengers waiting for each car by analyzing an image captured by the camera. In this case, the height of the passenger, the silhouette of the body, the color of the clothes, etc. may be analyzed from the image of the camera, and this may be acquired as the information of the passenger, or the face of the passenger may be recognized. The crowded state in this case is the number of passengers in the car 13.

  In the detection of congestion in the car 13 by the load detection device 48, the weight is measured by the load detection device 48 which detects a load on the floor of the car 13 as shown in FIG. The congestion state in this case is the value of the load applied to the car 13. The control system of the elevator according to the present embodiment sets in advance the standard weight as a reference, and calculates the congestion status in the car 13 according to the following equation (1). The crowded state in this case is the number of passengers in the car 13.

Measurement result of the load detection device 48 ÷ standard weight = the number of passengers in the car 13 ... Formula (1)
The standard weight is set as 60 kg as an example. However, the standard weight value is not limited to 60 kg. Also, the value of standard weight may be changeable.

  The group management control device 11 acquires information on the congestion status in the car 13 (13a, 13b, 13c, ...) from the elevator control device 12 (12a, 12b, 12c, ...). The group management control unit 11 acquires information on the number of passengers of the hall 14 where the hall destination floor registration device 15 has been operated from the hall 14. Thereafter, based on these pieces of information, the car 13 is selected and assigned to the hall 14.

  The group management control unit 11 outputs a hall call assignment signal to the elevator control unit 12 that controls the assigned car 13. For example, when a landing call is assigned to the car 13a, an assignment signal is output to the elevator control device 12a.

  In the group management control device 11, since the destination floor of the passenger can be known in advance, when there are many passengers who want to go to the same floor, the operation efficiency can be improved by assigning the same car.

  FIG. 5 is a block diagram of the functions of the group management control unit 11 and the elevator control unit 12. The group management control device 11 includes a hall number of people detecting unit 111, a congestion status detecting unit 112, a calculating unit 113, a determining unit 114, and an allocating unit 115. Each elevator control device 12 includes an in-car information acquisition unit 121 and a position information acquisition unit 122.

  The hall number detection unit 111 is a circuit for detecting the number of passengers waiting for destination floor registration at the hall 14 (14a, 14d) provided with the hall destination floor registration device 15. The station number detection unit 111 transmits information on passengers detected by at least one of the card reading unit 19 of the station 15 and the hall imaging device 34 provided in the hall 14 (14a, 14d) as a transmission cable. Receive via 2 and detect the number of passengers. Hereinafter, the number of passengers waiting at the landing 14 (14a, 14d) will be denoted as NL.

  The congestion status detection unit 112 is a circuit that detects the congestion status for each of the plurality of cars 13 (13a, 13b, 13c,...). The congestion state detection unit 112 is provided in the elevator control device 12 (12a, 12b, 12c...) Corresponding to each of the cars 13 (13a, 13b, 13c. Information is collected and acquired, and the congestion status is detected for each car 13.

  The congestion status is information on the congestion status detected by at least one of the car image pickup device 47 and the load detection device 48. The congestion state detected by the car imaging device 47 is the number of people (people) in the car 13. The congestion state detected by the load detection device 48 is the value (kg) of the load applied in the car 13.

  The calculation unit 113 is a circuit that calculates the possible number of passengers for each car 13 from the rated capacity of the car 13 and the detection result of the congestion state detection unit 112. The rated capacity is the load that can be applied to the car 13, or the number of passengers that can be accommodated in the car 13.

  When the rated capacity is a load that can be applied to the car 13, the rated capacity may be the maximum loading capacity (kg) of the car 13, and a predetermined ratio (for example, 60%) to the maximum loading capacity. It may be multiplied by). The rated capacity in this case is referred to as the rated weight.

  When the rated capacity is the number of passengers that can be accommodated in the car 13, the rated capacity may be the maximum number of people (persons) that can be accommodated in the car 13, and a predetermined ratio for the maximum number of people It may be multiplied by (for example, 60%). The rated capacity in this case is referred to as the rated number of people.

  The calculation unit 113 calculates the possible number of passengers by taking the difference of the congestion status from the rated capacity. The number of possible passengers is hereinafter referred to as NC.

  For example, the rated capacity is set to a rated weight (kg), and the congestion state is set to a value (kg) of a load detected by the load detection device 48. The calculation unit 113 can calculate the possible number of passengers NC from the following equation (2).

Possible number of passengers NC = (rated capacity (kg)-crowded situation (kg)) / standard weight-Formula (2)
For example, the rated capacity is set as the rated number of people (person), and the congestion state is set as the number of people (persons) in the car 13 detected by the car imaging device 47. The calculation unit 113 can calculate the possible number of passengers NC from the following equation (3).

Possible number of passengers NC = rated capacity (person)-crowded situation (person) ... Formula (3)
For example, the rated capacity is assumed to be a rated weight (kg), and the congestion state is assumed to be the number of people (people) in the car 13 detected by the car imaging device 47. The calculation unit 113 can calculate the possible number of passengers NC from the following equation (4).

Possible number of passengers NC = rated capacity (kg) / standard weight-crowded situation (person) ... Formula (4)
The standard weight used in the formulas (2) and (4) is the same as the standard weight (for example, 60 kg) used in the formula (1).

  The determination unit 114 is a circuit that determines whether the passengers of the hall 14 where the hall destination floor registration device 15 is provided can be boarded for each car 13 from the information of the hall number detection unit 111 and the calculation unit 113. Determination unit 114 compares the number of passengers waiting at landing 14 detected by landing number detection unit 111 with the magnitude relationship between NL and the number of people NC who can travel and detected by calculation unit 113. Do.

  The determination unit 114 determines that, for a certain car 13, if NL> NC, it is not possible to board a passenger waiting at the hall 14 at the car 13. If NL ≦ NC for a certain car 13, the determination unit 114 determines that it is possible to board a passenger waiting at the hall 14 at the car 13.

  The allocating unit 115 is a circuit that selects the car 13 of the car 1 from the cars 13 that the judging unit 114 has determined to be able to get on, and allocates the car 13 to the hall 14 (14a, 14d) where the hall destination floor registration device 15 is operated.

  The allocation unit 115 extracts the car 13 in which NL ≦ NC based on the determination result of the determination unit 114. When there are a plurality of cars 13 satisfying NL ≦ NC, the allocation unit 115 registers the current position of the car 13 determined to be boardable by the judgment unit 114 and the destination floor registration in the hall destination floor registration device 15 The car 13 may be assigned to the landing 14 based on the distance between the landing 14 and the floor of the landing 14.

  In FIG. 1, the case where the landing 14 where the destination floor registration operation is performed is the landing 14d will be examined. The car 13a, 13b, 13c is a car 13 capable of getting on. In the case of assigning a weight to the congestion status, the assignment unit 115 selects and assigns one of the relatively empty cars 13b and 13c. When considering the distance in addition to the crowded situation, one of the cars 13a and 13c relatively close to the landing 14d is selected and assigned.

  At the time of assignment, registration information of the destination floor by the landing destination floor registration device 15 and the current lifting and lowering direction of the car 13 may be considered. That is, one in which the direction from the landing 14 to the destination floor registered and the direction in which the elevator car 13 is moved matches is selected and assigned.

  Further, even if the direction from the landing 14 to the destination floor registered does not match the moving up and down direction of the car 13, registration of the destination floor registration device 42 in the car 13 is the landing destination floor registration device 15. In the case of ending at the floor near the operated landing 14, the car 13 can be assigned.

  The in-car information acquisition unit 121 is a circuit that acquires information on passengers in the car 13 by at least one of the car imaging device 47 and the load detection device 48. The in-car information acquisition unit 121 acquires information on the passengers in the car 13 and then transmits the information to the congestion status detection unit 112 via the transmission cable 1.

  The position information acquisition unit 122 is a circuit that acquires information on the current position of the car 13. The position information of the car 13 can be determined, for example, based on the pulse of a pulse generator provided in a hoist (not shown) of the elevator. Moreover, a sensor can be provided in the hoistway of an elevator, and the position of the car 13 can be acquired by the sensitivity of a sensor. However, the method of acquiring the position information of the car 13 is not limited to these. Further, the position information acquisition unit 122 may acquire information on the current lifting and lowering direction of the car 13.

  The position information acquisition unit 122 transmits the position information of the car 13 and the elevation information to the group management control device 11 via the transmission cable 1.

  Next, the operation of the first embodiment will be described. FIG. 6 is a flowchart of control in the control system of the elevator according to the first embodiment. Hereinafter, the case where the destination floor is registered at the landing 14d will be described in detail.

  The control system of the elevator in this embodiment determines whether the destination floor has been registered from the hall destination floor registration device 15d at the landing 14d (step S100). If the destination is not registered (NO in step S100), the determination is continuously performed. When destination registration is performed (YES in step S100), the number of people NL of the passengers of the hall 14d is detected by the hall number of people detection unit 111 (step S101). The congestion status detection unit 112 detects the congestion status of each car 13 (step S102).

  The order of steps S101 and S102 may be reversed. That is, the congestion status of each car 13 may be detected (step S102), and thereafter the number NL of passengers of the landing 14d may be detected (step S101). Moreover, you may process simultaneously with step S101 and step S102.

  After the congestion status of each car 13 is detected (step S102), the number of possible passengers NC of each car 13 is calculated by the calculation unit 113 (step S103). The determination unit 114 compares the number NL of passengers of the landing 14d with the number of people NC who can get on each car 13, and determines the presence or absence of the car 13 assigned to the landing 14d (step S104).

  When there is a car 13 in which the relationship between the number of passengers NL at the landing 14 d and the number NC of available passengers is NL ≦ NC (YES in step S 104), the allocating unit 115 determines that the passenger 13 at the landing 14 d Is assigned as an aircraft that can be boarded (step S105).

  If the relationship between the number NL of passengers of the landing 14d and the number NC of available passengers is NL> NC for any of the cars 13 (NO in step S104), the possible number NC of available passengers is calculated again (step S103). That is, the calculation is repeated until a car which can be assigned to the landing 14d is generated.

  As a specific embodiment of the present embodiment, there is the following aspect as an example.

  The landing 14a provided with the landing destination floor registration device 15a is a reference floor such as an entrance hall, and the landing 14d provided with the landing destination floor registration device 15d is a floor used by an unspecified number of persons such as commercial facilities. . The landing 14d is located in the middle of the floors of the elevator. The landings 14 other than the landings 14a and 14d are office floors or the like, and are floors that only a specific person uses. The landing destination floor registration device 15 is not provided at the landings 14 other than the landings 14a and 14d, and the elevator call device 18 is provided.

  In FIG. 1, it is assumed that a passenger waiting at the landing 14d performs destination floor registration to the reference floor 14a at the landing destination floor registration device 15d. At the time of lunch break, when returning home, etc., a passenger may get down to the standard floor 14a on an office floor (hall 14e, 14f,...) Higher than the landing 14d.

  In FIG. 1, conventionally, after the car 13a is assigned to the hall 14d, reservation registration of the car 13a is made at the hall 14e, and when a passenger of the hall 14e gets on, there are cases where the passengers of the hall 14d can not get on. The

  In the present embodiment, the number of passengers of the landing 14d and the congestion status of each of the cars 13 (13a, 13b, 13c...) Are detected, and the cars 13 are assigned.

  When the car 13a is allocated to the hall 14d, after the allocation, reservation registration is made at the hall 14e, and when a passenger of the hall 14e gets on, the flow of FIG. 6 is executed again to execute the car 13b. Alternatively, 13c may be assigned.

  Although the control of the elevator at the time of a lunch break or at the time of returning home of a building having a commercial facility and an office floor has been described in detail as a specific embodiment of the present embodiment, the present embodiment is not limited to the specific example.

  Although the hall destination floor registration device 15 is provided on the reference floor and the middle floor as a specific embodiment of the present embodiment, the hall destination floor registration device 15 may be provided only on the middle floor. There may be three or more landings 14 provided with the landing destination floor registration device 15.

  As described above, the elevator control system according to the present embodiment can assign a rideable car from the crowded state of the car and the number of passengers in the hall.

Second Embodiment
The control system of the elevator according to the second embodiment includes the diagram of the control system according to the first embodiment (FIG. 1), the schematic view of the hall destination floor registration apparatus (FIG. 2), and the hall provided with the hall destination floor registration apparatus. (FIG. 3), and a schematic view of the configuration in the car (FIG. 4).

  A block diagram of functions of the group management control device 11 and the elevator control device 12 of this embodiment is as shown in FIG. The group management control device 11 of the present embodiment further includes an adjustment unit 116 that adjusts the rated capacity based on the determination result by the determination unit 114.

  When the rated capacity is the rated weight, the control system of the elevator of this embodiment is the maximum load capacity multiplied by a predetermined ratio. Hereinafter, the predetermined ratio will be described as 60%. However, 60% is a value as an example of a predetermined ratio, and is not limited to this.

  In the present embodiment, the rated capacity at normal time is a value obtained by multiplying the maximum loading capacity by 60%. In the present embodiment, when a load exceeding the rated storage capacity is applied to the car 13 due to the passenger's boarding, a buzzer (not shown) provided in the car 13 sounds to notify that the vehicle is riding too much. That is, the rated capacity is the threshold of the load that can be loaded on the car 13.

  In the present embodiment, a value obtained by multiplying the maximum loading capacity by 60% by the calculating unit 113 is used as the rated storage capacity, and the boardable number of people NC is calculated from the formula (2) or the formula (4).

  FIG. 8 is a flow chart of control in the control system of elevator according to the second embodiment. The operation of the second embodiment will be described.

  The control of the control system of the elevator according to the present embodiment is the same as the processing of steps S100 to S104 and the processing of step S105 in the first embodiment.

  According to the comparison between the number of passengers NL at the landing 14 d and the number of people NC who can get on each car 13 by the determination unit 114, if NL> NC for any of the cars 13 (NO in step S104), this embodiment Changes the rated capacity, that is, the threshold value of the load capable of getting on the car 13 (step S200). For example, the predetermined percentage to be multiplied by the maximum load capacity is changed from 60% to 70%, and the possible number of passengers NC is calculated again (step S103). As a result, up to 70% of the maximum load capacity can be temporarily boarded, and passengers can be boarded more than usual.

  In the control of the control system of the elevator according to the present embodiment, the destination floor registration is performed in the landing destination floor registration device 15d, and if NL> NC for any of the cars 13, a passenger is required to board the passenger in the landing 14d. The threshold capacity rating of the car 13 can be temporarily changed.

  Even when the rated capacity is the rated number of people, the threshold may be similarly changed. For example, at normal times, the rated capacity is set to 10 people. If NL> NC for any of the cars 13 according to the determination by the determination unit 114 (NO in step S104), the rated capacity is set to 15 and the number NC of available passengers is derived again from equation (2) (Step S103). However, 15 persons and 10 persons of the rated capacity are examples, and it shall not be limited to this value.

  As described above, the elevator control system according to the present embodiment can assign a rideable car from the crowded state of the car and the number of passengers in the hall.

Third Embodiment

When the processing steps S300 and S301 are added to the flowchart of the first embodiment, the processing step S200 for changing the threshold is omitted.

  The elevator control system according to the present embodiment performs the car assignment process (step S105) to the landing 14d operated by the landing destination floor registration device 15d, and then, at an intermediate floor from the current position to the landing 14d. It is determined whether reservation registration has been made by the elevator call device 18 (step S300).

  When the reservation registration by the elevator call device 18 is not performed (NO in step S300), the control system of the elevator moves the car 13 to the landing 14d and lands.

  When reservation registration is performed by the elevator call device 18 (YES in step S300), the control system of the elevator according to the present embodiment determines the rated capacity of the car 13, ie, the threshold of the load that can get on the car 13. It changes (step S301).

  When the rated capacity is the rated weight, the control system of the elevator of this embodiment is the maximum load capacity multiplied by a predetermined ratio. Hereinafter, the predetermined ratio will be described as 60%. However, 60% is a value as an example of a predetermined ratio, and is not limited to this.

  In the present embodiment, the rated capacity at normal time is a value obtained by multiplying the maximum loading capacity by 60%. In the present embodiment, when a load exceeding the rated storage capacity is applied to the car 13 due to the passenger's boarding, a buzzer (not shown) provided in the car 13 sounds to notify that the vehicle is riding too much. That is, the rated capacity is the threshold of the load that can be loaded on the car 13.

  In the present embodiment, after the machine assignment process (step S105), when there is reservation registration on the way floor, the threshold which is the rated capacity is changed to, for example, 50% of the maximum loading capacity. Get in bed. That is, it is possible to leave an empty space in the car 13 for 10% of the maximum load capacity.

  For example, when the car 13a is assigned to the landing 14d and reservation registration is made at the landing 14e while moving to the landing 14d, the threshold value which is the rated capacity is changed from 60% to 50% of the maximum loading capacity do. When a load exceeding 50% of the maximum load capacity is detected at the landing 14e, a buzzer is sounded. As a result, it is possible to prevent a large number of passengers from getting on board at the landing 14e, and make it possible for the passengers at the landing 14d to board.

  Although the threshold value, which is the rated capacity after change, is 50% of the maximum load capacity, the threshold value is not limited to 50%.

  The control of the control system of the elevator according to the present embodiment can temporarily change the threshold value of the rated capacity of the car 13 in order to load the passengers of the hall 14d who operated the hall destination floor registration device 15d. .

  Even when the rated capacity is the rated number of people, the threshold may be similarly changed. For example, the rated capacity is usually set to 10 people. When reservation registration is performed by the elevator call device 18 after the allocation of units, the rated capacity can be set to 7 persons, and the space for 3 persons can be secured.

  As described above, the elevator control system according to the present embodiment can assign a rideable car from the crowded state of the car and the number of passengers in the hall.
