  In a building such as a department store where a plurality of elevator banks exist, for example, when an event is performed, the number of users is biased between banks. In the systems described in Patent Documents 1 and 2, the user cannot be appropriately guided in such a case. For example, when an event is held in a building, in a specific bank, the number of users increases rapidly immediately before and after the event starts. For this reason, the user may wait for a long time at the landing on the floor between the lobby floor and the floor serving as an event venue.

  In addition, in the thing of patent document 1, it is determined whether the elevator is crowded according to the number of registered calls. For this reason, the congestion situation in the car could not be accurately grasped. Further, the user cannot grasp the specific contents such as which driving direction is congested and where the stairs are from the display contents of the display device.

  The present invention has been made to solve the above-described problems. The purpose of the present invention is to appropriately provide elevator users according to the congestion situation of each bank when a plurality of elevator banks exist in a building. It is to provide an elevator system that can be guided.

An elevator system according to the present invention is an elevator system for guiding a user in a building having a plurality of elevator banks, and is provided on a predetermined floor of the building and disposed on an elevator landing in a predetermined bank. Bank load judgment that manages the load factor in each car on the floor where the hall indicator and the hall indicator are installed for each driving direction, and determines the congestion status of each bank on that floor for each driving direction A landing indicator is provided at the elevator landing on each floor in a predetermined bank, and the bank load determining means is the same as the bank having the landing indicator is crowded in a predetermined driving direction, and the same If other banks do not congested in the operating direction is present, the landing indicator, to display the guide map in the driving direction and another bank congested, landing indicator If the bank provided is congested across multiple floors in a given direction of operation, even if there are other banks on the same floor that are not congested in the same direction of operation On the floor display of the floor where the commute starts, the busy driving direction and the guide map to other banks are not displayed .
An elevator system according to the present invention is an elevator system for guiding a user in a building having a plurality of elevator banks, and is provided on a predetermined floor of the building, and is provided at an elevator landing in a predetermined bank. Bank that manages the load factor in each car on the floor where the hall indicator is located and the elevator on which the hall indicator is installed for each driving direction, and determines the congestion status of each bank on that floor for each driving direction Load judgment means, and the bank load judgment means is such that the load ratios in the elevator cars in the same bank are all equal to or higher than a predetermined value in one driving direction of the same floor, and the state continues for a predetermined time. In that case, it is determined that the floor of the bank is congested in one driving direction, the bank equipped with the landing indicator is congested in the predetermined driving direction, and If other banks do not crowded with the same driving direction is present, the landing indicator, is intended to display a guide map of the driving direction and another bank congested.

  In order to explain the present invention in more detail, it will be described with reference to the accompanying drawings. In addition, in each figure, the same code | symbol is attached | subjected to the part which is the same or it corresponds, The duplication description is simplified or abbreviate | omitted suitably.

Embodiment 1 FIG.
1 is a block diagram showing an elevator system according to Embodiment 1 of the present invention. This system is applied to buildings where there are multiple elevator banks. In the present embodiment, description will be given by taking as an example a case where three banks A to C exist in a building.

In FIG. 1, reference numeral 1 denotes a group management apparatus that manages a plurality of elevators as a group. In the present system, three group management devices 1 are provided corresponding to the number of banks.
In the following description, when it is necessary to individually specify the configuration of each bank, any one of A to C is added to the symbol. For example, the group management device of bank A is represented as 1A, the group management device of bank B is represented as 1B, and the group management device of bank C is represented as 1C. The same applies to other configurations.

A control device 2 is managed by the group management device 1. The control device 2 controls the operation of the elevator. In the present embodiment, each bank is provided with three elevators. That is, each group management device 1 manages three elevators (the control device 2).
In the following description, when it is necessary to specify the control device 2 individually, the bank number is followed by a machine number. For example, the control device for the elevator of the first unit in bank A is expressed as 2A1, the control device for the second unit in bank B is expressed as 2B2, and the control device of the third unit in bank C is expressed as 2C3.

Each control device 2 is provided with a load factor calculation means 3, a communication control means 4, and a display control means 5.
The load factor calculation means 3 calculates the load factor in the corresponding elevator car. When the car stops at the landing, the load factor calculation means 3 detects the number of people getting on and off the car and identifies the number of people in the car. The number of passengers is detected based on, for example, the image from the car camera, the measurement result of the door sensor or the scale device. The load factor calculating means 3 calculates the in-car load factor from the specified number of people in the car and the capacity of the car.

  When the car passes through each floor, the communication control means 4 transmits car load information to the bank load determination device 7 described later. The car load information includes the in-car load factor calculated by the load factor calculating means 3 and the operation direction at that time (the moving direction of the car). For example, when the car passes through a landing, the communication control unit 4 transmits car load information to the bank load determination device 7 when the car reaches the landing position (height) of the landing. When the car stops at the landing, the communication control means 4 transmits car load information to the bank load determination device 7 when the car departs from the landing.

  Reference numeral 6 denotes a hall indicator provided at the elevator hall. The hall indicator 6 is installed in each hall of each elevator. The display control means 5 controls the display on the corresponding elevator hall display 6.

  In the following description, when it is necessary to individually specify the hall indicator 6, the floor symbol is added after the bank symbol and the machine number. In the present embodiment, the hall indicators 6 are installed on all floors (1F to 8F) of the building. For example, of the hall indicators installed on the 2nd floor (2F) of the building, those located at the landing of the first unit in bank A are 6A1-2F, and those located at the landing of the second unit in bank A are 6A2. -2F. Similarly, of the hall indicators installed on the 8th floor (8F) of the building, the one located at the hall of Bank C No. 3 is denoted as 6C3-8F.

  The bank load determination device 7 determines the congestion status of each bank for each floor and for each driving direction. The bank load determination device 7 is connected to each group management device 1 and receives car load information from the communication control means 4 of each control device 2 via the corresponding group management device 1.

The bank load determination device 7 includes a storage unit 8, a determination unit 9, and a display command unit 10.
FIG. 2 is a diagram for explaining the function of the bank load determination device. As shown in FIG. 2, the load factor in the car of each elevator is stored in the storage unit 8 for each floor and each driving direction. When the bank load determination device 7 receives the car load information from the communication control unit 4, the bank load determination device 7 updates the corresponding in-car load factor stored in the storage unit 8 and keeps the value always the latest state.

  The determination unit 9 determines the congestion status of each bank for each floor and each driving direction based on the car load factor managed by the storage unit 8. For example, when the load factor in the elevator car in the bank is equal to or more than a predetermined value in one driving direction of the same floor and the state continues for a predetermined time, the determination means 9 It is determined that the floor is congested in the one driving direction (predetermined congested state).

  The display command means 10 outputs a command (display command) for causing the hall display 6 to display predetermined contents. The display command means 10 outputs a display command with appropriate contents according to the determination result of the determination means 9. When the display control means 5 of each control device 2 receives a display command from the display command means 10, the display control means 5 causes the corresponding hall indicator 6 to display according to the received content.

  Next, the operation of the elevator system having the above configuration will be described with reference to FIGS. FIG. 3 is a flowchart showing the operation of the elevator system according to Embodiment 1 of the present invention, and FIG. 4 is a view showing a display example of a hall indicator.

  In each control device 2, the communication control unit 4 transmits the car load information to the bank load determination device 7 when the corresponding car passes through the floor. When the bank load determination device 7 receives the car load information (S101), the car load factor stored in the storage unit 8 is updated based on the received content.

  When the bank load determination device 7 receives the car load information, the determination unit 9 determines whether the received in-car load factor is high (S102). For example, when the received car load factor is a predetermined value (for example, 80%) or more, the determination unit 9 detects that the car load factor of the floor and the driving direction is high.

  When the determination means 9 determines that the load factor in the car is low (for example, less than 80%) (No in S102), the elevator display control means 5 displays the display on the hall display 6 installed on the floor. Is not particularly changed. If the display of the hall display 6 until then is normal content, the display control means 5 continues the normal display (S103). For example, if the load factor in the car on the second floor of the first unit of bank A is 10% in the downward direction (see FIG. 2), the display control means 5 of the control device 2A1 sends a predetermined normal value to the hall indicator 6A1-2F. Display the contents. In such a case, the display command means 10 may or may not output a predetermined display command to the control device 2A1.

  When the load factor in the car received from the communication control means 4 is high (Yes in S102), the determination means 9 has a high load factor in the car in the same driving direction on the same floor in the bank (for example, 80%). (S104). When there is a low (for example, less than 80%) load factor in the car in the same driving direction (No in S104), the elevator display control means 5 is a hall indicator installed on the floor. The display of 6 is not particularly changed (S103).

  For example, if the in-car load factor on the second floor of the third unit of bank B is 80% in the downward direction (see FIG. 2), the determination unit 9 determines that the in-car load factor is high (Yes in S102). The load factor in other cars on the second floor of Bank B is 50% for Unit 1 in the downward direction and 40% for Unit 2 in the downward direction. In such a case, since the other car has a low car load factor, the display control means 5 of the control device 2B3 does not change the display of the hall indicator 6B3-2F. For example, the display control means 5 of the control device 2B3 causes the hall display 6B3-2F to display normal contents as before.

  In the same floor in the bank, when the load factor in the car in the same driving direction is all high (hereinafter, this state is also referred to as “high load state”) (Yes in S104), the determination means 9 determines that the high load state is It is determined whether or not it continues for a long time (S105). For example, when the high load state continues for a predetermined time (for example, 15 minutes) or more, the determination unit 9 detects that the floor of the bank is congested in the driving direction.

  When it is determined by the determination means 9 that the floor is not crowded (No in S105), the display control means 5 of the elevator does not particularly change the display of the hall indicator 6 installed on the floor ( S103).

  For example, if the in-car load factor on the seventh floor of the first unit of bank A is 90% in the downward direction (see FIG. 2), the determination unit 9 determines that the in-car load factor is high (Yes in S102). The load factor in the car of the other unit on the 7th floor of Bank A is 90% in the downward direction for both Unit 2 and Unit 3. For this reason, the determination means 9 determines that the downward direction of the seventh floor in the bank A is in a high load state. However, if the high load state has not continued for 15 minutes or more, the determination means 9 determines that the seventh floor of the bank A is not congested in the downward direction. In such a case, each display control means 5 of the control devices 2A1 to 2A3 does not change the display of the hall indicators 6A1-7F, 6A2-7F, 6A3-7F. For example, the display control means 5 of the control device 2A1 causes the hall display 6A1-7F to display normal contents as before.

  When a certain floor in the bank is congested in a predetermined driving direction (Yes in S105), the determination means 9 is the same floor and the same driving direction, and there is an elevator with a low car load factor. It is determined whether there is any other bank (S106).

  In the above example, when the downward high load state continues for 15 minutes or more on the seventh floor of bank A, the determination means 9 determines that the downward direction is congested on the seventh floor of bank A (S105). Yes). The load factor in the same floor and the same driving direction of the other banks is, for example, 80% for the first unit in the bank B and 30% for the first unit in the bank C. That is, an elevator with a low car load factor exists in bank C (the other bank) (Yes in S106). In such a case, each display control means 5 of the control devices 2A1 to 2A3 has a direction of operation in which congestion occurs on the floor of the hall indicators 6A1-7F, 6A2-7F, 6A3-7F, and the load factor in the car. A guide map to bank C where there is an elevator with a low is displayed (S107).

FIG. 4 shows a display example of the hall indicators 6A1-7F at this time. Reference numeral 11 shown in FIG. 4 denotes a landing door of the first bank A machine installed on the seventh floor of the building, and reference numeral 12 denotes a landing button provided in the vicinity of the landing door 11. On the hall indicators 6A1-7F, a plan view of the seventh floor of the building is displayed, and an arrow indicating the route from the current location (bank A) to bank C is superimposed on the plan view. Moreover, on the hall indicators 6A1-7F, the driving directions that are congested in the bank A are displayed in characters below the plan view.
The user who sees the display on the hall indicators 6A1-7F understands that the bank C is empty and can move to the bank C.

  On the other hand, in the above example, when the elevator load factor in the downward direction of the seventh floor is 80% or more in all elevators in bank C, there is no elevator with a low elevator load factor in other banks ( No in S106). In such a case, each display control means 5 of the control devices 2A1 to 2A3 has the driving directions in which congestion occurs on the floors of the hall indicators 6A1-7F, 6A2-7F, 6A3-7F, and the stairs in the building. Alternatively, a guide map to the escalator is displayed (S108). For example, a plan view of the seventh floor of the building is displayed on the hall display 6A1-7F, and an arrow indicating the route from the current location (bank A) to the escalator is displayed superimposed on the plan view. In addition, the driving directions that are congested in the bank A are displayed on the hall indicators 6A1-7F by characters below the plan view.

Note that the process shown in FIG. 3 may be performed for each car load factor at a predetermined cycle.
In S106, the determination unit 9 may determine whether there is another bank that is not congested in the same floor and the same driving direction.

  With the elevator system having the above configuration, when there are a plurality of elevator banks in a building, the elevator user can be appropriately guided according to the congestion status of each bank. In particular, since the congestion status of each bank is detected for each driving direction, users in the opposite direction are not guided to other banks when congestion occurs only in one driving direction. There is no fear that it will fall. Moreover, when all the banks are congested (the load is high), the user can be appropriately guided to the place where the stairs and the escalator are installed.

In the present embodiment, the bank load determination device 7 is connected to each group management device 1. However, this is only an example, and the group management device 1 may be provided with the functions of the bank load determination device 7. In such a case, it is not necessary to install an independent device as the bank load determination device 7.
Moreover, in this Embodiment, although the hall indicator 6 is installed in each hall of each elevator,
Even if the hall indicator 6 is installed in each bank of each floor, the same effect can be obtained.

Embodiment 2. FIG.
FIG. 5 is a flowchart showing the operation of the elevator system according to Embodiment 2 of the present invention. Below, with reference to FIG. 5, operation | movement of the elevator system in this Embodiment is demonstrated. The system configuration is the same as that shown in FIG.

The processing shown in S201 through S206 is the same as the processing shown in S101 through S106 in FIG.
In S206, when there is another bank where there is an elevator with a low car load factor in the same floor and the same driving direction, the determination means 9 determines whether the bank is congested (congested floor). Are determined in the same operation direction (S207). For example, when a high load state in the downward direction continues for 15 minutes or more on the 7th floor of bank A, and there is an elevator with a low car load factor on the 7th floor of bank C (another bank) (FIG. 2). The determination means 9 determines whether or not the lower direction is congested on the upper and lower floors of the seventh floor of the bank A.

  In the example shown in FIG. 2, when the downward high load state continues for 15 minutes or more on the 8th and 6th floors of the bank A, the 6th to 8th floors correspond to continuous crowded floors (Yes in S207). ). In such a case, each display control means 5 of the control devices 2A1 to 2A3 has landing indicators 6 (6A1-6F, 6A2-6F, 6A3-6F, 6A1-7F, 6A2-7F, 6A2-7F, 6A3-7F) displays the driving direction in which the floor is congested and a guide map to bank C where there is an elevator with a low car load factor. On the other hand, each display control means 5 of the control devices 2A1 to 2A3 displays the above driving directions and guide maps on the 8th floor landing display 6 (6A1-8F, 6A2-8F, 6A3-8F) at the beginning of congestion. It is not displayed (S208).

  When the downward direction is not congested on both the 8th and 6th floors of bank A (that is, when there is no congestion across a plurality of consecutive floors in the downward direction), FIG. This is the same as the processing in S107. Each of the display control means 5 of the control devices 2A1 to 2A3 is an elevator having a low driving direction and a low load factor in the car in the hall indicators 6A1-7F, 6A2-7F, 6A3-7F. And a guide map to the bank C where is present (S209).

  Further, even when the determination unit 9 determines No in S206, the determination unit 9 performs the same process as in S207 (S210). And in the said bank, when congestion has occurred over a plurality of continuous floors (Yes in S210), the floor display 6 of the crowded floor other than the floor where the congestion starts is displayed on the floor. The driving direction in which the congestion is occurring and the guide map to the stairs or escalator in the building are displayed (S211). Further, when the congested floors are not continuous in the same driving direction (No in S210), the congested floor landing display 6 indicates the driving direction in which the congested floor is generated and the stairs or escalator in the building. The guide map to the is displayed (S212).

  If the elevator system has the above configuration, the users on the floor where congestion starts will use the elevator, and only the users on the intermediate floor that are expected to increase waiting time can be used for other banks and stairs. Can be guided appropriately.

  The elevator system according to the present invention can be applied when a plurality of elevator banks exist in a building.
