According to the technique disclosed in Patent Document 1, information for guiding a user is depicted in a space or projected on a floor surface. However, in order to realize this technique, it is necessary to provide a car-shooting camera in the car, and a landing depiction device and a landing-shooting camera at the landing on each floor, which complicates the system configuration. In addition, if the inside of the car or the front of the landing door is crowded, it becomes difficult to see the information depicted in the space or projected on the floor.

The present invention has been made in view of such a situation, and an object of the present invention is to make it easier for passengers at the landing to grasp the state of the car.

The elevator system according to the present invention can provide car destination information and operation information to elevator users at the landing. This elevator system determines the status of the car based on the information display unit installed at a position higher than the line of sight of the passenger near the landing door and the operation data of the car moving in the hoistway. , The state judgment unit that outputs the judgment result, the destination information indicating the moving direction of the car moving toward the landing floor where the landing door is installed, and the operation information indicating the operating state of the car based on the judgment result. The information display unit is provided with a display control unit that controls the display of the information display unit by dividing the display area into upper and lower parts with different background colors for each divided area. The display control unit covers the entire display area. It is controlled to display the destination information and the operation information on the information display unit by switching to either the full screen display as the screen or the divided screen display in which the display area is divided, and the state determination unit is based on the operation data. , When the time required for the car to arrive at the landing floor where the landing call is registered is calculated, the display control unit takes time for the car to arrive at the landing floor above the display area displayed on the split screen. The information corresponding to the time is displayed as operation information, and the destination information is displayed below the display area displayed on the split screen. When the number of passengers that can be ridden is calculated for the maximum number of passengers, the display control unit displays information corresponding to the number of passengers that can be ridden on the upper side of the display area displayed on the split screen as operation information, and the display area displayed on the split screen. When the destination information is displayed on the lower side and the status determination unit determines that the passenger is not in the car and the car is waiting on the landing floor, the display control unit displays a split screen. Information indicating that the car can be boarded is displayed on the upper side of the displayed display area as operation information, and when the state determination unit determines that the car is full, the display control unit displays a split screen. Information indicating that the car cannot be boarded is displayed on the upper side of the display area as operation information, and the status judgment unit outputs a judgment result including that the car stops at the landing floor where the destination floor call is registered. If this is the case, the display control unit will provide information indicating that the passenger will get off the vehicle from the vehicle above the display area displayed on the split screen, based on the determination result, according to the timing when the vehicle arrives at the landing floor. Display as operation information.

According to the present invention, since the destination information and the operation information are displayed for each divided area in which the display area of the information display unit is divided into a predetermined size, the types of information that can be provided to the passengers at the landing are increased. It becomes easier for passengers to grasp the condition of the car.

Hereinafter, embodiments for carrying out the present invention will be described with reference to the accompanying drawings. In the present specification and the drawings, components having substantially the same function or configuration are designated by the same reference numerals, and redundant description will be omitted.

[First Embodiment]
First, the elevator system according to the first embodiment of the present invention will be described.
FIG. 1 is a schematic view showing a configuration example of the elevator system 1 according to the first embodiment.

The elevator system 1 includes elevators 10 of Units A to N. Each elevator 10 includes a car 3 that moves in the hoistway, a unit control device 2 (an example of a control device) that controls the operation of the car 3, a landing door 41 provided on each landing floor of the hoistway, and a landing. It includes a call button 42 and a lantern 43 (an example of an information display unit). The operation of the car 3 of each unit is controlled by the unit control device 2 provided for each unit. The landing door 41, the landing call button 42, and the lantern 43 are each connected to the unit control device 2 by a signal line (not shown).

The opening and closing of the landing door 41 is linked to the opening and closing of the car door 31 of the car 3 that has arrived at the landing floor. By opening the car door 31 and the landing door 41, the passenger can get on the car 3 or the passenger can get off from the car 3. Further, the car door 31 and the landing door 41 are closed while the car 3 is moving away from the landing floor. In addition, the car door 31 and the landing door 41 are closed when a predetermined time elapses after all the passengers in the car 3 get off. The opening and closing of the car door 31 and the landing door 41 is controlled by the operation control unit 21 of the unit control device 2.

The landing call button 42 is a button for the user to call the car 3 to the landing floor. When the landing call button 42 is pressed, call registration is performed on the landing floor where the landing call button 42 is installed. Then, a call registration signal is transmitted from the landing call button 42 to the unit control device 2.

The lantern 43 is installed according to the position of the landing door 41, and provides guidance information to the passengers at the landing, particularly the passengers near the landing door 41. The lantern 43 is composed of, for example, a liquid crystal display monitor, an organic EL (Electro Luminescence) monitor, etc., and can display the entire guidance information, and also divides one screen to display a plurality of guidance information. Is also possible. Detailed examples of the guidance information displayed on the lantern 43 are shown in FIGS. 5 and 6 described later.

The car 3 moves up and down in the ascending or descending direction in the hoistway while balancing with a balance weight (not shown). The operation of the car 3 is controlled by the unit control device 2. When the car 3 arrives at the landing floor, the car door 31 opens and passengers can get on and off the car 3. The car 3 is provided with a weight sensor 32 (an example of a passenger detection unit) that detects the weight of the passengers on the floor in the lower part of the floor. The weight sensor 32 detects a passenger in the car 3. When the weight sensor 32 detects that the weight of the passenger in the car 3 exceeds the specified weight, a buzzer sound prompting the passenger to get off is emitted from the speaker. Further, when the weight sensor 32 detects the weight of the passenger in the car 3, the weight sensor 32 transmits this detection information as operation data to the unit control device 2.

The unit control device 2 of Units A to N includes an operation control unit 21, a state determination unit 22, and a display control unit 23. The unit control device 2 and the car 3 of each unit have the same configuration.

The operation control unit 21 controls the operation of the car 3. For example, when the call registration signal is received by pressing the landing call button 42, the car 3 is controlled to move to the landing floor to which the call registration signal is transmitted. Further, when the destination floor button (not shown) in the car 3 is pressed, the car call signal is transmitted from the destination floor button. Therefore, when the operation control unit 21 receives the car call signal, the operation control unit 21 controls to move the car 3 to the destination floor designated by the destination floor button.

The state determination unit 22 receives operation data received from the car 3 (for example, the position of the car 3, the door open / closed state, the on / off of the door sensor attached to the car door 31, information including the weight of the passenger, and the like. The state of the car 3 is determined based on (including). Then, the state determination unit 22 outputs the determination result of the state of the car 3 to the display control unit 23.

Here, the state determination unit 22 divides the detection information including the weight of the passenger received from the car 3 by the weight per adult to determine the number of passengers in the car 3. You can ask. Therefore, the state determination unit 22 can determine whether the car 3 is moving in a full state or whether some people can afford to ride. Then, the state determination unit 22 outputs the determination result regarding the number of passengers in the car 3 to the display control unit 23.

The display control unit 23 controls to display the destination information and the operation information for each divided area obtained by dividing the display area of the lantern 43 into a predetermined size based on the determination result input from the state determination unit 22. The destination information is information indicating the moving direction of the car 3 moving toward the landing floor where the landing door 41 is installed. The operation information is information indicating the operation state of the car 3, and includes, for example, the number of passengers in the car 3, the time required for the car 3 to arrive at the landing floor, and the like. In the present embodiment, information including at least one of destination information and operation information is also referred to as "guidance information". The guidance information displayed on the lantern 43 changes depending on the state of the car 3.

Then, the display control unit 23 switches to either a full-screen display in which the display area of the lantern 43 is the full screen or a split screen display in which the display area is divided, and sends the destination information and / or the operation information to the lantern 43. Control the display. Further, the display control unit 23 can control the lantern 43 to display an upward arrow as the destination information of the ascending car 3 and the downward arrow as the destination information of the descending car 3. ..

Next, the hardware configuration of the computer 5 constituting each device of the elevator system 1 will be described.
FIG. 2 is a block diagram showing a hardware configuration example of the computer 5. For example, the unit control device 2 is composed of a computer 5.

The computer 5 is hardware used as a so-called computer. The computer 5 includes a CPU (Central Processing Unit) 51, a ROM (Read Only Memory) 52, and a RAM (Random Access Memory) 53, which are connected to the bus 54, respectively. Further, the computer 5 includes a non-volatile storage 55 and a network interface 56.

The CPU 51 reads the program code of the software that realizes each function according to the present embodiment from the ROM 52 and executes it. Variables, parameters, etc. generated during the arithmetic processing of the CPU 51 are temporarily written in the RAM 53. The CPU 51 realizes the functions of the operation control unit 21, the state determination unit 22, and the display control unit 23 included in the unit control device 2.

As the non-volatile storage 55, for example, HDD (Hard Disk Drive), SSD (Solid State Drive), flexible disk, optical disk, optical magnetic disk, CD-ROM, CD-R, magnetic tape, non-volatile memory and the like are used. Be done. In this non-volatile storage 55, in addition to the OS (Operating System) and various parameters, a program for operating the computer 5 is recorded. The ROM 52 and the non-volatile storage 55 record programs, data, and the like necessary for the CPU 51 to operate, and as an example of a computer-readable non-transient recording medium in which a program executed by the computer 5 is stored. Used.

For the network interface 56, for example, a NIC (Network Interface Card) or the like is used, and various data can be transmitted and received between the devices via a LAN (Local Area Network) connected to the terminals of the NIC, a dedicated line, or the like. It is possible. For example, the unit control device 2 receives operation data and a car call signal from the car 3 through the network interface 56. Further, the unit control device 2 transmits guidance information to the lantern 43 through the network interface 56.

Next, the installation position of the lantern 43 will be described.
FIG. 3 is an explanatory diagram showing an example of the installation position of the lantern 43.

As described above, the lantern 43 is installed near the landing door 41 for each unit on each landing floor. FIG. 3 shows that the lantern 43 is installed above the three-sided frame 45 arranged around the landing door 41, for example, at a position higher than the line of sight of a passenger near the landing door 41. Since the lantern 43 is installed at a position higher than the landing door 41 in this way, even if the passengers are crowded in the elevator hall on the landing floor, the passengers can easily read the contents displayed on the lantern 43.

The perspective view (1) of FIG. 3 shows a configuration example of the perspective lantern 43, and the top view (2) shows a configuration example of the lantern 43 viewed from above. The lantern 43 shown in FIG. 3 is composed of substantially triangular prisms having a bottom surface and an upper surface in the shape of a substantially isosceles triangle, and is a display device arranged one by one on both side surfaces of an installation table 44 provided on a three-sided frame 45. It is a generic term. The information displayed by the display devices on both sides of the installation table 44 is the same. Therefore, the same information can be confirmed by both the passengers in front of the elevator hall and the passengers in the back of the elevator hall.

The passenger who presses the landing call button 42 waits for the arrival of the car 3 in front of the landing door 41. At this time, the lantern 43 displays the destination information and the operation information of the car 3. Here, since the destination information and the operation information are displayed separately at the same time, the user can easily confirm the state of the car 3.

Here, a modified example of the installation position of the lantern 43 will be described.
FIG. 4 is an explanatory view showing a modified example of the installation position of the lantern 43.

The lantern 43 may be directly attached to the vertical frame or the horizontal frame of the three-sided frame 45 without passing through the installation base 44. FIG. 4 shows an example in which one lantern 43 is attached to each of the vertical frames inside the three-sided frame 45. Even if the lantern 43 is attached in this way, the passenger can confirm the destination information and the operation information of the car 3.

The lantern 43 may be attached only to the vertical frame at the back of the vertical frame of the three-sided frame 45 according to the direction in which the user enters the elevator hall. For example, the white arrow 46 shown in FIG. 4 indicates the moving (elevating) direction of the passenger who intends to get in the car 3. In this case, the lantern 43 is attached only to the vertical frame on the left side of FIG. As a result, the moving passenger can check the state of the car 3 and, for example, select the machine in which the car 3 with a small number of passengers is operating and press the landing call button 42. Or you can wait in front of the landing door 41.

Next, the guidance information displayed on the lantern 43 will be described with reference to FIGS. 5 and 6.
FIG. 5 is a user interface diagram showing an example of guidance information displayed on the lantern 43. This explanatory diagram shows guidance information according to the states (1) to (5) of the car 3 and an example of the background color. Here, the arrow displayed on the lantern 43 is an example of destination information, and the gauge, number, message, etc. displayed on the lantern 43 are an example of operation information.

(1) Lifting display The lifting display is a function in which the lantern 43 informs the user of the moving direction of the car 3. When the car 3 moves up and down, the state determination unit 22 determines that the car 3 is moving up and down. Then, the display control unit 23 displays the destination information of the car 3 on the lantern 43 based on the determination result.

For example, as shown in (1-1), the lantern 43 displays the destination information of the car 3 having a black background color on the entire screen. This destination information is displayed in full screen on the lantern 43 as an arrow indicating the moving direction of the car 3. When the car 3 is descending, the lantern 43 displays a vertically scrolling white arrow pointing downward from the top to the bottom of the lantern 43. Although not shown, when the car 3 is rising, the lantern 43 displays a vertically scrolling white arrow pointing upward from the bottom to the top of the lantern 43. The lantern 43 may be displayed by vertically scrolling the black arrow, with the background color being white and the arrow indicating the moving direction of the car 3 being black.

When the car 3 arrives at the landing floor, the state determination unit 22 determines that the car 3 has stopped. The display control unit 23 displays the destination information of the car 3 on the lantern 43 based on the determination result.

For example, as shown in (1-2), the lantern 43 represents destination information by flicker display in which the background color and the color of the arrow are inverted. Inversion of the background color and the color of the arrow is performed, for example, at 1-second intervals. Further, the lantern 43 stops the vertical scrolling of the arrow.

(2) Arrival prediction The arrival prediction is a function in which the lantern 43 predicts the time when the car 3 arrives at the landing floor and informs the passenger of the estimated time. Therefore, the state determination unit 22 obtains the time required for the car 3 to arrive at the landing floor where the landing call is registered, based on the operation data. Then, the display control unit 23 displays information (gauges, numbers, etc.) corresponding to the time required for arrival on the lantern 43 as operation information.

For example, as shown in (2-1), the lantern 43 displays the time required for the car 3 to arrive, with the background color set to dark gray in the upper half of the divided screen. Gauges and numbers are counted down and displayed until the car 3 arrives at the landing floor. Further, as shown in (1-1), the lantern 43 displays the destination information in the lower half of the divided screen.

Here, the gauge and the number are both examples of operation information. For example, the gauge represents the time expected to take for the car 3 to reach the landing floor, and the gauge shown in white decreases as the car 3 approaches the landing floor. Then, when the car 3 stops at the landing floor, the gauge shown in white disappears. In addition, the number represents the time expected to take for the car 3 to arrive at the landing floor in seconds. For example, if "15 more to arrive" is displayed, it can be seen that it was expected that it would take 15 seconds for the car 3 to arrive at the landing floor.

The car 3 may stop on the middle floor until the car 3 arrives. In this case, the lantern 43 stops the decrease of the gauge shown in the upper half of the divided screen and stops the decrease of the number. For example, the number displayed as "8" does not change until the car 3 starts moving again. In addition, the lantern 43 blinks and displays the message "Getting on and off." Even in this case, the lantern 43 displays the destination information shown in (1-1) in the lower half of the divided screen.

The lantern 43 may display either a gauge or a number. Further, the content displayed on the lantern 43 is not limited to the gauge or the number as long as it indicates the content of the expected arrival of the car 3 to the passenger near the landing door 41. For example, a symbol, a mark, or the like may be displayed on the lantern 43.

(3) Standby status The standby status is a function in which the lantern 43 notifies a passenger near the landing door 41 that the number of passengers who can board the car 3 and that the car 3 is waiting on the landing floor. Therefore, the state determination unit 22 obtains the number of passengers who can ride the passenger car 3 based on the number of passengers of the car 3 obtained based on the operation data. Then, the display control unit 23 displays information corresponding to the number of passengers on the lantern 43 as operation information.

For example, as shown in (3-1), the lantern 43 displays the operation information indicating the standby status on the upper half of the divided screen with the background color set to white. For example, if there are three passengers available for the passenger capacity of the car 3, the lantern 43 displays the message "up to three more passengers can be accommodated." Further, the lantern 43 displays the destination information shown in (1-1) in the lower half of the divided screen.

Further, if the passenger is not in the car 3 and the car 3 is waiting on the landing floor, the state determination unit 22 determines that the number of passengers in the car 3 is 0. Then, the display control unit 23 provides, as information corresponding to the number of passengers, the operation information that informs the passenger near the landing door 41 where the car 3 is stopped that the car 3 can be boarded. Displayed on the lantern 43.

For example, as shown in (3-2), the lantern 43 displays the message "You can get on while waiting." In this case, the passenger can get on the car 3 after pressing the car call button on the landing floor to open the car door 31 and the landing door 41.

(4) Alert The alert is a function in which the lantern 43 alerts a passenger near the landing door 41. A warning is given when the number of passengers in the car 3 is equal to or greater than the passenger capacity. Therefore, when the state determination unit 22 determines that the car 3 is full based on the number of passengers in the car 3 obtained based on the operation data, the state determination unit 22 determines that the number of passengers that can be boarded is 0. Then, the display control unit 23 displays on the lantern 43, as information corresponding to the number of passengers that can be boarded, the operation information that informs the passenger who intends to board that the car 3 cannot be boarded.

For example, as shown in (4-1), the lantern 43 displays the message "It is full. I cannot ride." The background color of this message is, for example, yellow. When this message is displayed, the passenger can determine that he / she cannot board the car 3. In the alert, the lantern 43 may display this message, and the speaker (not shown) installed in the car 3 may emit a buzzer sound, a voice message, or the like.

In addition, a warning is also given when a passenger in the car 3 gets off at the landing floor. Therefore, the state determination unit 22 outputs a determination result including that the car 3 stops at the landing floor where the destination floor call is registered. Then, the display control unit 23 displays on the lantern 43 as operation information information indicating that the passenger gets off from the car 3 based on the determination result in accordance with the timing when the car 3 arrives at the landing floor. ..

For example, as shown in (4-2), the lantern 43 displays the message "Please move away from the door." The background color of this message is, for example, yellow. When a passenger near the landing door 41 reads this message, he / she leaves the vicinity of the landing door 41. Therefore, the passenger can get off smoothly from the car 3.

(5) Stop display The stop display is a function for notifying that the operation of the car 3 is stopped. When the operation of the car 3 is stopped due to an earthquake or the like, the state determination unit 22 determines that the car 3 is stopped. Then, the display control unit 23 displays the operation information of the car 3 on the lantern 43 based on the determination result.

For example, as shown in (5-1), the lantern 43 displays a warning message "Cannot be used for a while" as operation information in full screen. The background color of this warning message is, for example, red. A passenger near the landing door 41 reads this warning message and knows that the elevator 10 is currently unavailable.

In addition, while the maintenance and inspection of the elevator 10 is being carried out, the lantern 43 displays the guidance message "The elevator cannot be used for a while during the inspection" as the operation information on the full screen as shown in (5-2). indicate. The background color of this guidance message is, for example, green. When the passenger near the landing door 41 reads this guidance message, he / she knows that he / she should use the elevator 10 of another unit that has not been maintained and inspected.

FIG. 6 is a user interface diagram showing an example in which the guidance information of the lantern 43 changes. The guidance information of the lantern 43 changes in the order of (1) immediately after allocation, (2) steady state, (3) deceleration, and (4) arrival.

(1) Immediately after allocation Immediately after the call is assigned to the car 3, for example, when the car 3 rises toward the landing floor, the lantern 43 displays an upward arrow in full screen. On the other hand, when the car 3 descends toward the landing floor, the lantern 43 displays the downward arrow in full screen (see (1-1) in FIG. 5).

(2) Steady state The steady state is a state in which the car 3 is ascending or descending. For example, if the car 3 is raised, the lantern 43 displays the destination information represented by the up arrow in the upper half of the divided screen, and the waiting time and gauge in the lower half of the divided screen. Display operation information. Further, for example, if the car 3 is descending, the lantern 43 displays the destination information represented by the downward arrow in the lower half of the divided screen, and displays the waiting time and the gauge in the upper half of the divided screen. The operation information to be displayed is displayed (see (2-2) in FIG. 5).

(3) During deceleration When the car 3 approaches the registered landing floor, the car 3 gradually slows down. At this time, the lantern 43 displays a warning message "Please move away from the door" (see (4-2) in FIG. 5).
(4) Arrival When the car 3 arrives at the registered landing floor, the car 3 stops. At this time, the lantern 43 displays a warning message "Please move away from the door" (see (4-2) in FIG. 5). Here, the lantern 43 performs a flicker display in which the arrow is inverted in black and white.

Next, a processing example of the elevator system 1 will be described with reference to FIG. 7.
FIG. 7 is a flowchart showing a processing example of the elevator system 1. This process is repeated at a predetermined control cycle (for example, every 1 second).

First, the state determination unit 22 determines whether or not the elevator 10 is in emergency operation (S1). When the state determination unit 22 determines that the vehicle is in emergency operation (YES in S1), the display control unit 23 displays emergency information on the entire surface of the lantern 43 (S2), and ends this process. The emergency information displayed at this time is, for example, the emergency stop information shown in (5-1) of FIG.

When the state determination unit 22 determines in step S1 that the elevator is not in emergency operation (NO in S1), that is, is in normal operation, the state determination unit 22 is assigned by the operation control unit 21 to call the elevator 10. Is determined (S3). When the state determination unit 22 determines that the call allocation of the elevator 10 has not occurred (NO in S3), the state determination unit 22 ends this process.

On the other hand, when the state determination unit 22 determines that the call allocation of the elevator 10 has occurred (YES in S3), the state determination unit 22 determines whether or not a predetermined time has elapsed from the occurrence of the call allocation (S4). The predetermined time is, for example, 3 to 5 seconds.

When the state determination unit 22 determines that the predetermined time has not elapsed since the occurrence of the call allocation (NO in S4), that is, the elapsed time from the occurrence of the call allocation is less than the predetermined time, the generated call allocation is performed. It is determined whether or not the allocation is in the upward direction (S5). When the state determination unit 22 determines that the generated call allocation is an ascending allocation (YES in S5), the display control unit 23 displays destination information (upward arrow) on the upper part (upper half) of the lantern 43. (S6), and this process is terminated.

In step S5, when the state determination unit 22 determines that the generated call allocation is not an ascending allocation (NO in S5), the display control unit 23 sends the destination information (downward) to the lower part (lower half) of the lantern 43. (Arrow) is displayed (S7), and this process ends.

When the state determination unit 22 determines in step S4 that a predetermined time has elapsed from the occurrence of the call allocation (YES in S4), the state determination unit 22 is decelerating for the car 3 to arrive at the allocation floor. It is determined whether or not it is (S8). When the state determination unit 22 determines that the car 3 is not decelerating (NO in S8), the state determination unit 22 determines whether or not the generated call allocation is an assignment in the ascending direction (S9).

When the state determination unit 22 determines that the generated call allocation is an ascending allocation (YES in S9), the display control unit 23 displays destination information (upward arrow) on the upper part (upper half) of the lantern 43. The operation information (1) is displayed in the lower part (lower half) (S10), and this process is completed. Here, the operation information (1) is information indicating the waiting time and the car state. For example, operation information such as (2) arrival forecast, (3) standby status, and (4-1) alerting in FIG. 5 is displayed on the lantern 43.

When the state determination unit 22 determines in step S9 that the generated call allocation is not an ascending allocation (NO in S9), the display control unit 23 sends destination information (downward arrow) to the lower part (lower half) of the lantern 43. ) Is displayed, the operation information (1) is displayed on the upper part (upper half) (S11), and this process is terminated.

When the state determination unit 22 determines in step S8 that the car 3 is decelerating (YES in S8), the state determination unit 22 determines whether or not the generated call allocation is an ascending allocation (S12).

When the state determination unit 22 determines that the generated call allocation is an ascending allocation (YES in S12), the display control unit 23 displays destination information (upward arrow) on the upper part (upper half) of the lantern 43. Then, the operation information (2) is displayed in the lower part (lower half) (S13), and this process is completed. Here, the operation information (2) is information indicating that there is a passenger getting off from the car 3. For example, (4-2) alerting in FIG. 5, (3) deceleration in FIG. 6, and (4) arrival operation information are displayed on the lantern 43.

When the state determination unit 22 determines in step S12 that the generated call allocation is not an ascending allocation (NO in S12), the display control unit 23 sends destination information (downward arrow) to the lower part (lower half) of the lantern 43. ) Is displayed, the operation information (2) is displayed on the upper part (upper half) (S14), and this process is terminated.

In the elevator system 1 according to the first embodiment described above, a lantern 43 capable of simultaneously displaying destination information and operation information of the car 3 in each divided area is provided near the landing door 41. Therefore, the passenger near the landing door 41 can easily select the unit he / she wants to board by looking at the information displayed on the lantern 43. Further, since the background color of the lantern 43 can be changed according to the state of the car 3, it is easy to alert or warn the passengers near the landing door 41.

As an example of the passenger detection unit, a camera capable of photographing the inside of the car may be provided in the upper part of the car of the car 3. The camera can detect the passengers in the car 3. The image taken by the camera is transmitted to the unit control device 2 as detection information at predetermined time intervals, and even if the state determination unit 22 analyzes the image and measures the number of passengers in the car 3. good. Thereby, for example, even if an infant or a wheelchair user is in the car 3, the state determination unit 22 can accurately measure the number of passengers. Then, the state determination unit 22 can output to the display control unit 23 a determination result of determining whether the car 3 is full, how many people can ride, etc., based on the empty space in the car 3. ..

Further, an example is shown in which destination information and operation information are displayed for each divided area of the display area divided into two of the lantern 43, but even if a plurality of operation information is displayed in each divided area. good. Further, the size of the divided area does not have to be the same. For example, in order to display the characters of the operation information in a large size, the divided area in which the operation information is displayed may be made larger than the divided area in which the destination information is displayed. good. On the contrary, the divided area in which the destination information is displayed may be larger than the divided area in which the operation information is displayed.

Further, by increasing the size of the lantern 43 itself, the display area of the lantern 43 may be divided into three or more, and various information may be displayed in each divided area. Further, although the lantern 43 can display the guidance information in color, a lantern capable of displaying only monochrome may be adopted.

[Second Embodiment]
Next, the elevator system according to the second embodiment of the present invention will be described.
FIG. 8 is a schematic view showing a configuration example of the elevator system 1A according to the second embodiment.

The elevator system 1A controls the operation of the car 3s of the plurality of units A to N in a group management manner. The elevator system 1A includes a car 3, a landing door 41 and a lantern 43, a machine control device 2A for controlling the operation of the car 3, a group management control device 7, and a destination floor call registration device 6. Be prepared. The unit control device 2A and the destination floor call registration device 6 are connected to the group management control device 7. The group management control device 7 can perform group management control of the car 3 of each unit based on the operating status of the car 3 of each unit.

In the second embodiment, instead of the landing call button 42, only one destination floor call registration device 6 is installed on the landing floor of each floor. A user heading to the landing floor can register the destination floor by, for example, holding an ID card or the like on which user information is recorded over the destination floor call registration device 6 provided at the entrance of the elevator hall. However, the user may register the destination floor by touching the numeric keypad or the like displayed on the destination floor call registration device 6. Then, the destination floor call registration device 6 displays the unit number indicating the elevator 10 on which the passenger can board. The passenger who has registered the destination floor waits in front of the landing door 41 corresponding to the displayed machine number, and when the car 3 arrives, he / she gets on the car 3.

The unit control device 2A (an example of the control device) includes an operation control unit 21, a state determination unit 22, a display control unit 23, and an operation data communication unit 24. The unit control device 2A provided in each unit controls the operation of the car 3 for each unit. The operation control unit 21, the state determination unit 22, and the display control unit 23 perform the same operations as each unit in the unit control device 2 according to the first embodiment described above. However, the operation control unit 21 operates according to the instruction of the group management control device 7.

The operation data communication unit 24 transmits the operation data of the car 3 to the group management control device 7. The timing at which the operation data communication unit 24 transmits the operation data to the group management control device 7 is, for example, when the destination floor call is registered in the destination floor call registration device 6, and the group management control device 7 to the unit control device 2A The transmission of operation data is started according to the transmission instruction given to. Further, the operation data communication unit 24 receives the group management information transmitted from the group management control device 7. The operation control unit 21 controls the operation of the car 3 based on the group management information received from the group management control device 7 via the operation data communication unit 24.

Next, a configuration example and an operation example of the group management control device 7 will be described with reference to FIG.
The group management control device 7 includes a unit operation control unit 71.

The unit operation control unit 71 calculates the allocation evaluation value for each unit based on the operation history of the car 3 of each unit because the destination floor call is registered in the destination floor call registration device 6. The allocation evaluation value is, for example, a value calculated based on the operating status of the car 3 of each unit. If the unit has a high allocation evaluation value, the destination floor call is preferentially assigned and the vehicle is dispatched. Therefore, the unit operation control unit 71 allocates the destination floor call to the unit for which the allocation evaluation value higher than the allocation evaluation value set for the other units is set. For example, when the unit A is assigned a destination floor call, the unit operation control unit 71 causes the unit control device 2A to perform operation control by group management in which the car 3 of the unit to which the destination floor call is assigned is preferentially dispatched. ..

Therefore, when the user operates the destination floor call registration device 6 to register the destination floor call, the unit operation control unit 71 acquires the call registration data from the destination floor call registration device 6. When the unit operation control unit 71 acquires the call registration data, the unit operation control unit 71 preferentially allocates the destination floor call to any of the units based on the allocation evaluation value of each unit. For example, the unit operation control unit 71 controls to preferentially allocate the vehicle 3 having the shortest waiting time from the vehicle 3 of each unit.

For example, it is assumed that the car 3 of Unit A is preferentially dispatched. In this case, the unit operation control unit 71 outputs the unit allocation signal to the unit control device 2A of the unit A to which the destination floor call is assigned. The unit control device 2A to which the unit allocation signal is input controls to move the car 3 to the landing floor where the destination floor call is registered according to the assigned destination floor call.

Also in the present embodiment, the lantern 43 displays the guidance information to the passenger near the landing door 41. In the group management control, when the destination floor call is registered, the number of passengers getting on and off the car 3 and the floor on which the passengers get on and off can be known. For this reason, it is possible to eliminate the need for operation information that informs the number of passengers that can be boarded in the car 3 that has stopped on the middle floor to the registered destination floor, as shown in (3) Standby status in FIG.

In the elevator system 1A according to the second embodiment described above, a mode in which the car 3s of a plurality of units are group-managed and controlled has been described. Even when the car 3 is controlled by group management in this way, the destination information and the operation information can be displayed on the lantern 43 provided in each unit. Therefore, the passenger near the landing door 41 can easily grasp the state of the car 3 of the unit to be boarded by looking at the information displayed on the lantern 43.

The state determination unit 22 and the display control unit 23 included in the unit control device 2A may be provided in the group management control device 7, so that the group management control device 7 may be used as an example of the control device. Then, the display of the lantern 43 of each unit may be controlled by the control of the group management control device 7.

Further, the present invention is not limited to the above-described embodiment, and it goes without saying that various other application examples and modifications can be taken as long as the gist of the present invention described in the claims is not deviated.
