Description

[Technical field]

[0001] The present disclosure relates to an information guidance system and an information guidance method for providing elevator passengers with information on getting on and off an elevator. [Background technology]

[0002] When an elevator car stops and the doors open, passengers at the landing may board the car and passengers inside the car may disembark. However, before the doors open, passengers at the landing cannot know in advance whether any passengers will disembark from the car, and passengers inside the car cannot know in advance whether any passengers will board the car.

[0003] For this reason, if both passengers get on and off the train carelessly, there is a risk that they will collide with each other. In order to avoid such collisions, Japanese Patent Laid-Open Publication No. 6-87581 (Patent Document 1) describes a technology for turning on the alighting indicator light for a floor when the destination floor indicated by the destination floor button pressed inside the car is a floor where a hall call (boarding call) is occurring.

[0004] [Patent Document 1] Japanese Patent Application Publication No. 6-87581 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the technology described in Patent Document 1 simply turns on the alighting indicator light at the boarding hall, and does not allow passengers to intuitively grasp the possibility of a collision between boarding and alighting passengers.

[0006] The present disclosure has been made to solve the above-mentioned problems, and its purpose is to provide an information guidance system and an information guidance method that enable intuitive understanding of the possibility of collisions between passengers boarding and disembarking. [Means for solving the problem]

[0007] The information guidance system according to the present disclosure is a system that provides information on passengers getting on and off an elevator. The information guidance system includes call buttons and a control unit. The control unit controls the display mode of the call buttons. The call buttons include call buttons including a car call button provided in the car, an upward platform call button provided at the landing, and a downward platform call button provided at the landing. When a call is registered from any of the car call button, the upward platform call button, and the downward platform call button, the control unit changes the display mode of the call button corresponding to the call depending on the passenger status when the doors open in response to the call.

[0008] The information guidance method according to the present disclosure is a method for providing information on passengers getting on and off an elevator. The information guidance method includes a step of controlling a display mode of call buttons including a car call button provided in a car, an upward platform call button provided at a landing, and a downward platform call button provided at a landing. The step of controlling includes a step of, when a call is registered from any of the car call button, the upward platform call button, and the downward platform call button, changing the display mode of the call button corresponding to the call depending on the status of passengers getting on and off when the doors open in response to the call. Effect of the Invention

[0009] According to the present disclosure, the possibility of a collision between passengers boarding or disembarking can be intuitively grasped. [Brief description of the drawings]

[0011] Hereinafter, an embodiment will be described with reference to the drawings. In the following description, the same components are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed description thereof will not be repeated.

[0012] [Information Guidance System 1] First, the configuration of the information guidance system 1 will be described. Fig. 1 is a diagram showing an example of an elevator hall in this embodiment. Fig. 2 is a diagram showing an example of the inside of a car 100. Fig. 2(a) is a diagram showing the inside of the car 100 as seen from the front, and Fig. 2(b) is a diagram showing the inside of the car 100 as seen from the side. Fig. 3 is a diagram showing an example of the overall configuration of the information guidance system 1.

[0013] The information guidance system 1 according to this embodiment is a system that provides information about passengers getting on and off an elevator. In this embodiment, it is assumed that the building in which the elevator is installed is four stories tall. It is assumed that the elevator equipment installed in the building includes hall devices installed at the halls of each floor from the first floor (1F) to the fourth floor (4F), and equipment including one car 100 that runs in a hoistway. The car 100 can stop at each floor from the first floor to the fourth floor.

[0014] In this embodiment, the upward direction is also called the "UP direction" and the downward direction is also called the "DN direction." An UP direction hall call is also called an "UP call," a DN direction hall call is also called a "DN call," and a destination floor call in a car is also called a "car call." The buttons for registering these calls are called "call buttons."

[0015] The call buttons include a car call button provided in the car 100, an upward platform call button (also referred to as an "UP call button") provided at the platform, and a downward platform call button (also referred to as a "DN call button") provided at the platform.

[0016] In addition, the control device 10 described below can detect calls from call buttons corresponding to wheelchairs (referred to as "wheelchair calls"). As with the above calls, wheelchair calls include wheelchair car calls, UP wheelchair calls, and DN wheelchair calls. Call buttons corresponding to wheelchair calls (referred to as "wheelchair call buttons") include a wheelchair car call button corresponding to a wheelchair car call, an UP wheelchair call button corresponding to a UP wheelchair call, and a DN wheelchair call button corresponding to a DN wheelchair call.

[0017] Each floor is provided with a hall operating panel. Here, the hall on the first floor is taken as an example for explanation. As shown in FIG. 1, the hall on the first floor is provided with a door 260, a hall operating panel 250, and a camera 220.

[0018] A camera 220 installed at the 1F landing can capture images of people (waiting passengers) at the 1F landing. A landing operation panel 250 is provided with an UP call button 231, a DN call button 232, an UP wheelchair call button 241, and a DN wheelchair call button 242. For example, when the UP call button 231 is pressed, an UP call on the 1F is registered.

[0019] The hall operating panel 250 is provided with an indicator 151. The indicator 151 displays the running direction of the car 100 and the running or stopping floor. In the example shown in the figure, it is shown that the car 100 is running or stopping in the UP direction on the 2nd floor.

[0020] Next, the inside of the car will be described. As shown in Fig. 2(a), a door 160 and a car operation panel 150 are provided inside the car 100. The car operation panel 150 is provided with a door open button 152 for opening the door, a door close button 153 for closing the door, and a car call button for registering destination floors (car calls) from 1F to 4F.

[0021] The car call buttons include a 1F call button 131 for registering a car call to the 1st floor, a 2F call button 132 for registering a car call to the 2nd floor, a 3F call button 133 for registering a car call to the 3rd floor, and a 4F call button 134 for registering a car call to the 4th floor. The car operation panel 150 is also provided with an indicator 151 for displaying the travel direction of the car 100 and the travel floor or stop floor.

[0022] As shown in Fig. 2(b), a camera 120 and a car operation panel 180 for wheelchairs are provided inside the car 100. The camera 120 is capable of photographing people (passengers) inside the car 100. The car operation panel 180 is provided with an indicator 181, a door open button 182, a door close button 183, a 1F wheelchair call button 141 for registering a wheelchair car call to the 1st floor, a 2F wheelchair call button 142 for registering a wheelchair car call to the 2nd floor, a 3F wheelchair call button 143 for registering a wheelchair car call to the 3rd floor, and a 4F wheelchair call button 144 for registering a wheelchair car call to the 4th floor.

[0023] As shown in FIG. 3, the information guidance system 1 includes a control device 10, various devices installed in a car 100, a first floor landing device 200 installed at the first floor landing, a second floor landing device 300 installed at the second floor landing, a third floor landing device 400 installed at the third floor landing, and a fourth floor landing device 500 installed at the fourth floor landing.

[0024] The control device 10 is configured to be able to communicate with each of the car 100, the first floor hall device 200, the second floor hall device 300, the third floor hall device 400, and the fourth floor hall device 500.

[0025] The control device 10 includes a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, and a communication interface 14. These are connected to each other via a bus so that they can communicate with each other. The control device 10 controls the car 100 and the hall device.

[0026] The CPU 11 loads a program stored in the ROM 12 into the RAM 13 and executes it to realize various functions of the control device 10. The ROM 12 stores a program in which the processing procedures of the control device 10 are written.

[0027] The RAM 13 serves as a working area when the CPU 11 executes a program, and temporarily stores the program, data required for executing the program, and the like.

[0028] The control device 10 communicates with an in-car control device 110 of the car 100 via the communication interface 14. The in-car control device 110 controls the camera 120, detects calls from a 1F call button 131, a 2F call button 132, a 3F call button 133, a 4F call button 134, a 1F wheelchair call button 141, a 2F wheelchair call button 142, a 3F wheelchair call button 143, and a 4F wheelchair call button 144, and controls the display mode of these call buttons. In this way, the control device 10 can control various devices (the in-car control device 110, the camera 120, and each call button provided in the information guidance system 1) installed in the car 100.

[0029] The control device 10 communicates with a hall control device 210 of the first floor hall device 200 via the communication interface 14. The hall control device 210 controls the camera 220 to detect calls from the UP call button 231, the DN call button 232, the UP wheelchair call button 241, and the DN wheelchair call button 242, and controls the display modes of these call buttons.

[0030] The control device 10 communicates with the hall control device 310 of the second floor hall device 300 via the communication interface 14. The hall control device 310 controls the camera 320 to detect calls from the UP call button 331, the DN call button 332, the UP wheelchair call button 341, and the DN wheelchair call button 342, and controls the display modes of these call buttons.

[0031] The control device 10 communicates with a hall control device 410 of the third floor hall device 400 via the communication interface 14. The hall control device 410 controls the camera 420 to detect calls from the UP call button 431, the DN call button 432, the UP wheelchair call button 441, and the DN wheelchair call button 442, and controls the display modes of these call buttons.

[0032] The control device 10 communicates with a hall control device 510 of the fourth floor hall device 500 via the communication interface 14. The hall control device 510 controls the camera 420 to detect calls from the UP call button 531, the DN call button 532, the UP wheelchair call button 541, and the DN wheelchair call button 542, and controls the display modes of these call buttons.

[0033] As a result, the control device 10 can detect calls from the cameras and call buttons connected to the car in-control device 110 and the hall control devices 210, 310, 410, 510, and control the display modes of these call buttons.

[0034] Here, "display mode" includes the light emission color, the lit state, and the flashing state of the call button. In this embodiment, the call buttons (hall call buttons and car call buttons) are configured to include light-emitting bodies such as LEDs. The call buttons can be lit by the light emitted by the LEDs. In this embodiment, the call buttons can be lit in colors such as red, yellow, blue, purple, etc. The call buttons can also flash in these colors. The call buttons can also be lit in a display mode that changes the light emission color, such as red, purple, red, purple, etc.

[0035] When a hall call button is pressed, a call signal corresponding to the pressed hall call is transmitted to the control device 10. The control device 10 registers the hall call. The control device 10 then assigns a car 100 to the registered hall call and determines the display mode of the hall call button corresponding to the hall call. The control device 10 transmits a signal to change the display mode of the hall call button and causes the car 100 to respond to the registered hall call.

[0036] For example, when the DN call button 332 for 2F is pressed, a signal corresponding to the DN call for 2F is transmitted, and the control device 10 registers the DN call for 2F. The control device 10 determines the allocation of the car 100 to the DN call for 2F, and determines, for example, to light the DN call button 332 in blue. The DN call button 332 lights up in blue based on a command from the control device 10. In addition, the car 100 responds to the DN call for 2F, stops in the DN direction at 2F, and opens the door.

[0037] When a car call button is pressed, a call signal corresponding to the pressed car call is transmitted to the control device 10. The control device 10 registers the car call. The control device 10 then determines the display mode of the car call button corresponding to the registered car call. The control device 10 transmits a signal to change the display mode of the car call button, and causes the car 100 to respond to the registered car call.

[0038] For example, when the 2F call button 132 is pressed, a call signal corresponding to a car call to the 2F is transmitted to the control device 10. The control device 10 registers the car call to the 2F. Then, the control device 10 decides to, for example, cause the 2F call button 132 corresponding to a car call to the 2F to flash in red. The 2F call button 132 flashes in red based on a command from the control device 10. Also, the car 100 responds to the car call to the 2F and stops at the 2F and opens the door.

[0039] [Display of call buttons according to passenger boarding and alighting status] 4 to 13 are diagrams for explaining the display modes of the call buttons according to the passenger boarding and alighting situations.

[0040] In this embodiment, when a call is registered using any of the car call button, the UP call button, and the DN call button, the control device 10 changes the display mode of the call button corresponding to that call depending on the passenger boarding and alighting situation when the doors open in response to the call.

[0041] Here, "the doors open" means that the doors on both the car 100 side and the landing side open in conjunction with each other, and will hereinafter also be expressed as "the doors open." Similarly, "the doors close" means that the doors on both the car side and the landing side close in conjunction with each other, and will hereinafter also be expressed as "the doors close."

[0042] In addition, the "passenger boarding and alighting status" refers to a situation that indicates how a person (passenger) waiting for car 100 at the boarding area or a person (passenger) inside the car will behave when a call is registered and the doors open in response to the call.

[0043] For example, a case will be described in which a DN call (DN call at 2F) is registered at the boarding area on the 2nd floor. When a DN call at 2F is registered and an elevator car 100 traveling in the DN direction stops at 2F and opens the door in response to the DN call, the waiting passenger who registered this DN call attempts to board the elevator. In this way, a call is registered at the boarding area, and a person (passenger) who is scheduled to board when the door opens in response to this registered call is referred to as a "passenger scheduled to board." Note that a passenger scheduled to board may include passengers other than the passenger who registered the call, as long as he or she is scheduled to board the call.

[0044] However, even if there is a person at the boarding area, a person who does not intend to board is not included in the "passengers planning to board." For example, in the above example, there is a person who registered an UP call at the boarding area on the 2nd floor to go to a higher floor. Even if car 100 traveling in the DN direction responds to the DN call and stops at the 2nd floor and opens the door, the person who registered the UP call is not included in the "passengers planning to board" because they do not intend to board car 100. In other words, when the doors open in response to a DN call on the 2nd floor, a passenger who intends to board car 100 because he or she plans to go to a lower floor is a "passenger planning to board," but a passenger who does not intend to board car 100 because he or she does not plan to go to an upper floor is not a "passenger planning to board."

[0045] Furthermore, in the above example, assume that there is a person (passenger) who gets on the car 100 from the 4th floor and has registered a car call for the 2nd floor. In this case, when the car 100 stops at the 2nd floor, it responds to the DN call at the 2nd floor and also responds to the car call for the 2nd floor, opening the door at the 2nd floor. When the car 100 stops at the 2nd floor and opens the door in response to this car call for the 2nd floor, the person (passenger) who registered this car call intends to get off the car 100. In this way, a call is registered on the car side, and a person (passenger) who plans to get off when the door opens in response to this registered call is referred to as a "passenger who plans to get off." It should be noted that the passenger who plans to get off includes passengers other than the passenger who registered the call, as long as they plan to get off in response to the call.

[0046] However, even if there is a person in car 100, a person who has no plans to get off is not included in the "passengers planning to get off." For example, in the above example, it is a person (passenger) who has registered a car call for 1F to go to 1F. Even if the car responds to a car call for 2F and stops at 2F and opens the door, the person who registered the car call for 1F does not get off from car 100, so is not included in the "passengers planning to get off." In other words, when the door opens in response to a car call for 2F, a passenger who plans to go to 2F and intends to get off from car 100 is a "passenger planning to get off," but a passenger who plans to go to 1F and does not intend to get off from car 100 is not a "passenger planning to get off."

[0047] The passenger boarding / alighting status includes passenger boarding / alighting status A, passenger boarding / alighting status B, and passenger boarding / alighting status C. Passenger boarding / alighting status A is a passenger boarding / alighting status in which there are passengers planning to board and no passengers in the car 100 when the doors open, or there are no passengers at the landing and passengers planning to disembark when the doors open.

[0048] Passenger boarding / alighting status B is a passenger boarding / alighting status in which there are passengers planning to board when the doors open and there are people in the car 100 but no passengers planning to disembark, or there are people at the platform when the doors open but there are no passengers planning to board and there are passengers planning to disembark in the car 100.

[0049] Passenger boarding / alighting status C is a passenger boarding / alighting status in which there are passengers planning to get on and get off when the doors open. The control device 10 changes the display mode of the call button corresponding to the call depending on whether the passenger boarding / alighting status is A, B, or C.

[0050] In this embodiment, the control device 10 lights up the call button corresponding to the call in blue when the passenger boarding / alighting status is A. The control device 10 lights up the call button corresponding to the call in yellow when the passenger boarding / alighting status is B. The control device 10 lights up the call button corresponding to the call in red when the passenger boarding / alighting status is C.

[0051] In this embodiment, as described below, the likelihood of a collision increases in the passenger boarding / alighting statuses A, B, and C. Then, the call button is lit in red, yellow, and blue in order of the likelihood of a collision, corresponding to the colors of the traffic light. From the image of a traffic light, people can easily imagine that the degree of danger increases in the order of green, yellow, and red. In this way, passengers can intuitively grasp the possibility of a collision between passengers. Note that the order of the lights is not limited to blue, yellow, and red for the passenger boarding / alighting statuses A, B, and C, and any colors that make it easy to imagine a traffic light may be used. For example, blue may be changed to green.

[0052] Specifically, when a call (hall call or car call) is registered, if the passenger boarding / alighting situation when the doors open in response to the call is passenger boarding / alighting situation C, in which there are passengers planning to board and disembark when the doors open, the call button corresponding to the call will be lit in red.

[0053] In the case of passenger boarding / alighting status C, when the doors open, passengers planning to board will board and passengers planning to disembark will disembark, which may result in a collision between the passengers boarding and the passengers disembarking. Therefore, when a hall call is registered, the call button corresponding to that hall call is lit in red to inform passengers planning to disembark that there is a possibility of a collision when boarding. Also, when a car call is registered, the call button corresponding to that car call is lit in red to inform passengers planning to disembark that there is a possibility of a collision when disembarking.

[0054] When a call (a platform call or a car call) is registered, if the passenger boarding / alighting situation when the door opens in response to the call is passenger situation B where there are passengers planning to board and there are people in the car 100 but no passengers planning to disembark when the door opens, or there are people at the platform but no passengers planning to board and there are passengers in the car 100 when the door opens, the call button corresponding to the call is lit in yellow.

[0055] In the case of passenger boarding / alighting situation B, when the doors open, there are only passengers planning to board and passengers planning to disembark, so the possibility of passengers colliding with each other is lower than in passenger boarding / alighting situation C. However, when there are passengers planning to board on the platform side, there is a person on the car 100 side, so there is a possibility of passengers colliding with each other if the person on the car 100 side mistakenly disembarks. Also, when there are passengers planning to disembark on the car 100 side, there is a person on the platform side, so there is a possibility of passengers colliding with each other if the person on the platform side mistakenly boards the car.

[0056] For this reason, when a hall call is registered, the call button corresponding to the hall call is lit in yellow to inform passengers who plan to board that they may be involved in a collision when boarding if they get off by mistake. Also, when a car call is registered, the call button corresponding to the car call is lit in yellow to inform passengers who plan to disembark that they may be involved in a collision when disembarking if they get on by mistake.

[0057] When a call (a platform call or a car call) is registered, if the passenger boarding / alighting situation when the door opens in response to the call is passenger status A, in which there is a passenger planning to board and there is no person in the car 100 when the door opens, or there is no person at the platform and there is a passenger planning to disembark when the door opens, the call button corresponding to the call is lit in blue.

[0058] In the case of passenger boarding / alighting situation A, when the doors open, there is no one on the platform side or on the car 100 side, so there is no possibility of a collision when boarding or alighting. Therefore, when a platform call is registered, the call button corresponding to that platform call is lit in blue to inform passengers who plan to alight that there is no possibility of a collision when boarding. Also, when a car call is registered, the call button corresponding to that car call is lit in blue to inform passengers who plan to alight that there is no possibility of a collision when alighting. Specific examples will be described below with reference to Figs. 4 to 13.

[0059] Fig. 4 shows an example in which passenger boarding / alighting status C occurs and the call button is lit in red. As shown in Fig. 4(a), at the boarding area on the 2nd floor, person 802 who plans to go to the 1st floor registers a DN call using the DN call button 332. At this time, the car 100 is traveling in the DN direction between the 3rd floor and the 4th floor, and a car call to the 2nd floor has been registered using the 2nd floor call button 132. The car call to the 2nd floor was registered when person 801 boarded from the 4th floor.

[0060] In this embodiment, only one car (car 100) is installed in the building. Therefore, when a hall call is registered, car 100 is always assigned and responds to the hall call.

[0061] For example, in this example, when a DN call is registered at the landing of the 2nd floor, the car 100 is assigned to the DN call at the 2nd floor. The car 100 traveling in the DN direction responds to the DN call at the 2nd floor, stops at the 2nd floor, and then opens the door.

[0062] When the car 100 responds, the state becomes as shown in Fig. 4(b). The car 100 responds to the DN call registered by the person 802 at the boarding area on the 2nd floor, and also responds to the car call for the 2nd floor registered by the person 802 who boarded from the 4th floor, and opens the door.

[0063] Person 802 plans to go from the second floor to the first floor, and therefore attempts to board car 100 when the doors open. Person 802 is a passenger who plans to board when car 100 responds to a DN call on the second floor and opens the doors after stopping on the second floor, and therefore is a "passenger who plans to board."

[0064] On the other hand, person 801 who boarded on the 4th floor plans to get off on the 2nd floor, and so attempts to get off from car 100 when the door opens. Person 801 is a passenger who plans to get off when car 100 responds to a car call for the 2nd floor and opens the door after stopping at the 2nd floor, and is therefore a "passenger who plans to get off."

[0065] When a DN call for the 2nd floor is registered (FIG. 4(a)), the passenger status when the doors open in response to the DN call from the 2nd floor will be passenger status C (FIG. 4(b)) in which there are passengers planning to board and disembark when the doors open. Therefore, when a DN call from the 2nd floor is registered, the DN call button 332 corresponding to the DN call from the 2nd floor is lit in red.

[0066] Furthermore, the DN call registration on the 2nd floor also changes the passenger boarding / alighting status for car calls to the 2nd floor. The passenger boarding / alighting status when the doors open in response to a car call to the 2nd floor will be passenger boarding / alighting status C, in which there are passengers planning to board and disembark when the doors open, so the 2nd floor call button 132, which corresponds to car calls to the 2nd floor, is lit in red. Note that before the DN call registration on the 2nd floor, the status is the same as that shown in Fig. 6(a) described below, and the 2nd floor call button 132 is lit in blue.

[0067] In the above example, a car call to the 2nd floor is registered after a DN call to the 2nd floor is registered. If a car call to the 2nd floor is registered after a DN call to the 2nd floor is registered, the following occurs.

[0068] Assume that the car 100 opens its door on the 4th floor and a person 801 gets on. Then, assume that a car call to the 2nd floor is registered by the 2nd floor call button 132. At this time, assume that a DN call for the 2nd floor has already been registered by the DN call button 332.

[0069] When a car call to the 2nd floor is registered, the passenger boarding / alighting situation when the doors open in response to the car call to the 2nd floor is passenger boarding / alighting situation C, in which there are passengers planning to get on and passengers planning to get off when the doors open. Therefore, when a car call to the 2nd floor is registered, the 2nd floor call button 132 corresponding to the car call to the 2nd floor is lit in red.

[0070] Furthermore, by registering a car call for the 2nd floor, the passenger boarding / alighting status also changes for DN calls on the 2nd floor. The passenger boarding / alighting status when the doors open in response to a DN call on the 2nd floor will be passenger boarding / alighting status C, in which there are passengers planning to board and disembark when the doors open, so the DN call button 332 corresponding to the DN call on the 2nd floor is lit in red. Note that before a car call is registered for the 2nd floor, the DN call button 332 is lit in blue, as in Fig. 5(a) described below.

[0071] 5 to 7 show an example in which passenger boarding / alighting status A occurs and the call button is lit in blue. As shown in FIG. 5(a), the car 100 is traveling in the DN direction. There is no person in the car 100. At this time, it is assumed that a person 802 who is planning to go to the 1st floor at the boarding area on the 2nd floor has registered a DN call using the DN call button 332.

[0072] From the state of Fig. 5(a), when the car 100 stops at the 2nd floor and opens the door in response to a DN call registered at the boarding area of ​​the 2nd floor (the state of Fig. 5(b)), the person 802 is a passenger planning to board. However, at this time, there is no person in the car 100.

[0073] In other words, when a DN call on the 2nd floor is registered, when the door opens in response to the DN call on the 2nd floor, there is a passenger planning to board and there is no one in the car 100, which is passenger status A. Therefore, when a DN call on the 2nd floor is registered, the DN call button 332 corresponding to the DN call on the 2nd floor is lit in blue.

[0074] As shown in Fig. 6(a), there is no person at the platform for 2F. In this state, assume that a person 801 gets on the car 100 and a car call for 2F is registered by pressing the 2F call button 132.

[0075] When car 100 responds to a car call to the 2nd floor from the state shown in Fig. 6(a) and stops at the 2nd floor and opens the door (the state shown in Fig. 6(b)), person 801 is a passenger who plans to disembark. However, at this time, there is no person at the boarding area on the 2nd floor.

[0076] In other words, when a car call for the 2nd floor is registered, when the doors open in response to the car call for the 2nd floor, there is no one at the 2nd floor platform and no passengers planning to disembark, which is passenger boarding / alighting situation A. Therefore, when a car call for the 2nd floor is registered, the 2nd floor call button 132 corresponding to the car call for the 2nd floor is lit in blue.

[0077] As shown in Fig. 7(a), there is no person at the 3F boarding area. In this state, assume that person 801 gets on to car 100 at 4F and a car call to 3F is registered using 3F call button 132. In this case, as in the example of Fig. 6, since there is no person at 3F, 3F call button 132 lights up in blue. After that, at the 2F boarding area, assume that person 802, who plans to go to 1F, registers a DN call using DN call button 332. At this time, person 801 is in car 100.

[0078] However, as shown in Fig. 7(b), person 801 gets off at 3F when the car stops at 3F. Therefore, when the door opens at 2F in response to a DN call at 2F, the boarding / alighting passenger situation becomes A, in which there is a passenger planning to board and there is no person in car 100. Therefore, when a DN call at 2F is registered, DN call button 332 corresponding to the DN call at 2F is lit in blue.

[0079] 8 and 9 show an example in which passenger boarding / alighting status B occurs and the call button is lit in yellow. As shown in Fig. 8(a), in car 100 traveling in the DN direction between 4F and 3F, a car call to 1F is registered by person 801 using 1F call button 131. Also, at the 1F boarding area, an UP call is registered by person 804 using UP call button 231.

[0080] When the doors open at the 1st floor in response to a car call to the 1st floor and an UP call at the 1st floor, passenger status C is present, with a passenger planning to board (person 804) and a passenger planning to disembark (person 801), so the 1st floor call button 131 and the UP call button 231 are both lit red.

[0081] In this situation, assume that a DN call is registered by person 803 using DN call button 432 at the 3F boarding area. If car 100 stops at 3F and opens the door in response to this DN call at 3F, person 803 is a person planning to board, as shown in Fig. 8(b). Meanwhile, at this time, person 801 is in car 100, but is not planning to disembark at 3F. However, if car 100 stops at 3F and opens the door, person 801 may mistakenly disembark.

[0082] In other words, when the car 100 stops at the 3rd floor and opens the door in response to a DN call at the 3rd floor, this is passenger status B, in which there are passengers planning to board and people in the car 100 but no passengers planning to disembark. Therefore, when a DN call at the 3rd floor is registered, the DN call button 432 corresponding to the DN call at the 3rd floor is lit in yellow.

[0083] As shown in Fig. 9(a), assume that an UP call is registered by person 802 on the 2nd floor using the UP call button 331. Next, assume that person 801a gets into car 100 on the 4th floor, and a car call to the 1st floor is registered by person 801a using the 1st floor call button 131. Furthermore, assume that person 801b gets into car 100 on the 4th floor, and a car call to the 2nd floor is registered by person 801b using the 2nd floor call button 132.

[0084] In this case, car 100 starts traveling in the DN direction from 4F, then stops at 2F to respond to a car call to 2F, and then stops at 1F to respond to a car call to 1F. Next, car 100 reverses direction, starts traveling in the UP direction from 1F, and then stops at 2F to respond to an UP call to 2F.

[0085] When car 100 responds to a car call for the 2nd floor and stops at the 2nd floor and opens the door, person 801a is a passenger planning to disembark, as shown in Fig. 9(b). Meanwhile, at this time, person 802 is at the boarding area, but is not a passenger planning to board. However, there is a possibility that person 802 will mistakenly board the car.

[0086] In other words, when car 100 responds to a car call for the 2nd floor and stops at the 2nd floor and opens the door, this is passenger status B, in which there are passengers planning to disembark and people at the landing, but no passengers planning to board. For this reason, when a car call for the 2nd floor is registered, the 2nd floor call button 132 corresponding to the car call for the 2nd floor is lit in yellow.

[0087] If the car stops at 1F to respond to a car call for 1F, the 1F call button 131 lights up blue because there is no one at the boarding platform and 801a is a passenger planning to disembark, which is passenger status A. If the car stops at 2F to respond to an UP call for 2F, the 1F call button 131 lights up blue because there is no one at the boarding platform and 801a is a passenger planning to disembark, which is passenger status A.

[0088] 10 shows an example in which the passenger boarding / alighting situation changes from A to C. As shown in FIG. 10(a), the car 100 is traveling in the DN direction between 4F and 3F. At this time, there is no passenger in the car 100.

[0089] Assume that an UP call is registered by a person 804 on the first floor using the UP call button 231. When the door opens in response to the call, there is a passenger (person 804) who plans to board, but there is no one in the car 100, so the UP call button 231 lights up in blue.

[0090] Next, assume that on the second floor, a DN call is registered by person 802 using DN call button 332. When the door opens in response to the call, there is a passenger (person 802) planning to board, but no one is in car 100, so DN call button 332 lights up in blue.

[0091] Thereafter, when car 100 stops at the 2nd floor, person 802 gets on and registers a car call for 1st floor using 1F call button 131. In this case, the passenger boarding / alighting situation when the doors open in response to the car call for 1st floor is passenger boarding / alighting situation C, in which there is a passenger (person 804) who plans to get on and a passenger (person 802) who plans to get off when the doors open. Therefore, when a car call for 1st floor is registered, 1F call button 131 corresponding to the car call for 1st floor is lit in red.

[0092] Furthermore, at this time, the passenger status when the door opens in response to the UP call on the 1st floor changes to passenger status C in which there is a passenger who plans to get on (person 804) and a passenger who plans to get off (person 802) when the door opens. For this reason, the UP call button 231 changes from blue to red.

[0093] In this embodiment, the control device 10 further changes the display mode of the call button corresponding to the call depending on whether a passenger who plans to board or disembark based on a wheelchair call is included or not. In this embodiment, when a passenger who plans to board or disembark based on a wheelchair call is included, the control device 10 causes the call button to flash.

[0094] Furthermore, in this embodiment, the control device 10 can detect a predetermined motion of a person based on an image captured by a camera (camera 120, 220, 320, 420, 520) installed at the landing or inside the car. The control device 10 further differentiates the display mode of the call button corresponding to the call between when the predetermined motion is detected and when the predetermined motion is not detected. In this embodiment, the predetermined motion is a motion in which a person becomes violent. When the predetermined motion is detected, the call button is caused to flash. The predetermined motion may be any motion in which a person moves vigorously.

[0095] In this embodiment, the control device 10 can detect the number of passengers based on images captured by cameras (cameras 120, 220, 320, 420, 520) installed at the landing or inside the car. The control device 10 further differentiates the display mode of the call button corresponding to the call between a case where the detected number of passengers is a predetermined number (for example, 5 people) or more and a case where the detected number of passengers is less than the predetermined number. In this embodiment, when the detected number of passengers is the predetermined number or more, the call button is caused to blink. A specific description will be given below with reference to Figs. 11 to 13.

[0096] As explained with reference to FIG. 1, the cameras (cameras 220, 320, 420, 520) installed at the landing capture images of people (waiting passengers) at the landing at regular intervals. Image data captured by camera 220 etc. is transmitted to control device 10. Control device 10 detects people based on the difference between image data when there is no person at the landing and the captured image data. Control device 10 detects the number of people by counting the number of detected people. Also, based on the difference between the captured image data and the next captured image data, it detects the movement of people. When the difference in the movement of people is large, the movement of people becoming violent is detected as the predetermined movement. It should be noted that the number of people and the predetermined movement may be detected not only by control device 10 but also by a dedicated device capable of communicating with the camera.

[0097] Camera 120 installed inside car 100 captures images of people (passengers) inside car 100, as described with reference to Fig. 2. Similar to camera 220 installed at the landing, camera 120 captures images of people (passengers) inside car 100 at regular intervals. Image data captured by camera 120 is transmitted to control device 10. The method of detecting the number of people and the predetermined action is the same as in the case of camera 220.

[0098] The situation in Fig. 11 is similar to that in Fig. 4. A person 810 who boarded from the 4th floor registers a car call for the 2nd floor using the 2nd floor call button 132. After that, it is assumed that a predetermined movement (a violent movement) of the person 810 is detected by the camera 120 installed in the car.

[0099] In this state, assume that at the boarding area on the second floor, person 802 planning to go to the first floor registers a DN call using DN call button 332. In this case, similar to the case in Fig. 4, when car 100 arrives at the second floor and the door opens, passenger boarding / alighting situation C occurs. In addition, as shown in Fig. 11(b), person 810 is acting violently, making the situation even more dangerous. In this case, when a DN call for the second floor is registered, the corresponding DN call button 332 flashes in red.

[0100] When a DN call on the 2nd floor is registered, if violent behavior is not detected by the camera 120, the DN call button 332 is lit in red, as in the case of Fig. 4. In this way, when violent behavior is detected, the display mode of the call button is made more alert than when violent behavior is not detected.

[0101] Note that the DN call button 332 may be changed from a lit red color to a flashing red color at the timing when the violent behavior is detected by the camera 120. In addition to the DN call button 332, the 2F call button 132 may also be made to flash red.

[0102] The situation in Fig. 12 is similar to that in Fig. 4. Assume that a DN wheelchair call is registered by person 811 at the boarding area on the 2nd floor using DN wheelchair call button 342. In this state, assume that person 801 who boarded from the 4th floor registers a car call to the 2nd floor using 2nd floor call button 132.

[0103] In this case, similar to the case of Fig. 4, when car 100 arrives at 2F and the door opens, the passenger boarding / alighting situation is C (person 811 is a passenger planning to board and person 801 is a passenger planning to disembark). In addition, as shown in Fig. 12(b), person 811 is a passenger planning to board based on a wheelchair call, so this is a situation that requires more caution to avoid a collision. In this case, when a car call for 2F is registered, the corresponding car call button 132 is made to flash in red.

[0104] Unlike the above, when there are no passengers planning to board (or disembark) based on a wheelchair call, the car call button 132 is lit in red, as in the case of Fig. 4. In this way, when there are passengers planning to board (or disembark) based on a wheelchair call, the display mode of the call button is made more alert than when there are no passengers planning to board (or disembark) based on a wheelchair call.

[0105] In addition, if the timing at which a DN wheelchair call is registered by the DN wheelchair call button 342 is later than the timing at which a car call to the 2nd floor is registered by the 2nd floor call button 132, the 2nd floor call button 132 may be changed from lit to flashing at the timing at which the DN wheelchair call button 342 is registered.

[0106] The situation in Fig. 13 is similar to that in Fig. 4. Suppose that a DN call is registered by DN call button 332 at the 2nd floor hall. At this time, suppose that there are multiple people 820 (five people) at the hall heading to a lower floor. Camera 320 installed at the 2nd floor hall captures images of multiple people 820. Then, suppose that it is determined that there are five people at the hall based on the captured images of multiple people 820, and that the number of people at the hall is equal to or greater than a predetermined number (five people).

[0107] In this state, assume that a passenger 801 who boarded from the 4th floor registers a car call for the 2nd floor using the 2nd floor call button 132 .

[0108] In this case, similar to the case in Fig. 4, when car 100 arrives at 2F and the door opens, the passenger boarding / alighting situation is C (multiple people 820 are passengers planning to board and person 801 is a passenger planning to alight). In addition, as shown in Fig. 13(b), it is determined that the number of people 802 at the boarding area is equal to or greater than a predetermined number (five people), so this is a situation that requires greater caution to avoid collisions. In this case, when a car call for 2F is registered, the corresponding car call button 132 flashes in red.

[0109] Unlike the above, when the number of detected people 802 is less than a predetermined number (5 people), the car call button 132 is lit in red, as in the case of Fig. 4. In this way, when the detected number of people is equal to or greater than the predetermined number, the display mode of the call button is made more alert than when the detected number of people is less than the predetermined number.

[0110] [flowchart] The CPU 11 included in the control device 10 executes a main process. The main process is a process for determining the display mode of a call button corresponding to a call when the call is registered. The main process is started every time a call is registered. Alternatively, the main process may be started periodically.

[0111] 14 is a flowchart of the main processing executed by the CPU 11. The CPU 11 executes the main processing. Hereinafter, "step" may also be simply referred to as "S".

[0112] As shown in Fig. 14, when the main processing starts, the CPU 11 determines in S1 whether or not there will be passengers planning to board and there will be no passengers in the car 100 when the door of the car 100 opens. If the CPU 11 determines in S1 that there will be passengers planning to board and there will be no passengers in the car 100 when the door of the car 100 opens (YES in S1), the processing proceeds to S6. On the other hand, if the CPU 11 does not determine in S1 that there will be passengers planning to board and there will be no passengers in the car 100 when the door of the car 100 opens (NO in S1), the processing proceeds to S2.

[0113] In S2, the CPU 11 determines whether or not there is a person at the landing and a person planning to disembark in the car 100 when the door of the car 100 opens. If the CPU 11 determines in S2 that there is a person at the landing and a person planning to disembark in the car 100 when the door of the car 100 opens (YES in S2), the CPU 11 proceeds to processing S6. On the other hand, if the CPU 11 does not determine in S2 that there is a person at the landing and a person planning to disembark in the car 100 when the door of the car 100 opens (NO in S2), the CPU 11 proceeds to processing S3.

[0114] In S3, the CPU 11 determines whether or not there are passengers planning to board and in the car 100 but no passengers planning to disembark when the door of the car 100 opens. If the CPU 11 determines in S3 that there are passengers planning to board and in the car 100 but no passengers planning to disembark when the door of the car 100 opens (YES in S3), the CPU 11 proceeds to processing S7. On the other hand, if the CPU 11 does not determine in S3 that there are passengers planning to board and in the car 100 but no passengers planning to disembark when the door of the car 100 opens (NO in S3), the CPU 11 proceeds to processing S4.

[0115] In S4, the CPU 11 determines whether or not there is a person at the landing but no one planning to board and there is a person planning to disembark in the car 100 when the door of the car 100 opens. If the CPU 11 determines in S4 that there is a person at the landing but no one planning to board and there is a person planning to disembark in the car 100 when the door of the car 100 opens (YES in S4), the CPU 11 proceeds to processing S7. On the other hand, if the CPU 11 does not determine in S4 that there is a person at the landing but no one planning to board and there is a person planning to disembark in the car 100 when the door of the car 100 opens (NO in S4), the CPU 11 proceeds to processing S5.

[0116] In S5, the CPU 11 determines whether or not there are passengers planning to get on and get off when the door of the car 100 opens. If the CPU 11 determines in S5 that there are passengers planning to get on and get off when the door of the car 100 opens (YES in S5), the CPU 11 advances the process to S8. On the other hand, if the CPU 11 does not determine in S5 that there are passengers planning to get on and get off when the door of the car 100 opens (NO in S5), the CPU 11 ends the main process.

[0117] In S6, the CPU 11 determines that the passenger boarding / alighting status is passenger boarding / alighting status A, sets the button lighting color to blue, and ends the main processing. For example, the situations described with reference to Figs. 5 to 7 correspond to this situation.

[0118] In S7, the CPU 11 determines that the passenger boarding / alighting situation is passenger boarding / alighting situation B, sets the lighting color of the button to yellow, and advances the process to S9. For example, the situation described with reference to Figs. 8 and 9 corresponds to this situation.

[0119] In S8, the CPU 11 determines that the passenger boarding / alighting situation is passenger boarding / alighting situation C, sets the lighting color of the button to red, and advances the process to S9. For example, this situation corresponds to the situation described with reference to FIG.

[0120] In S9, the CPU 11 executes blinking determination processing and ends the main processing. The blinking determination processing determines whether or not to set the blinking of the button. When the main processing ends, the target call button is made to light up or blink in the set color.

[0121] For example, if the illumination color of the call button is set to yellow and the button flashing is not set, the call button is illuminated in yellow. If the illumination color of the call button is set to red and the button flashing is set, the call button is flashed in red. Note that, if the hall call button for the stopping floor is flashed when the car 100 stops, it is preferable to make the flashing cycles of the call button due to the stopping of the car 100 different from the flashing of the call button due to the decision in the flashing determination process in order to distinguish between them.

[0122] As described above, the passenger boarding / alighting status includes passenger boarding / alighting status A, passenger boarding / alighting status B, and passenger boarding / alighting status C. Passenger boarding / alighting status B is a passenger boarding / alighting status in which there is a higher probability of a collision between boarding and alighting passengers when the doors open than in passenger boarding / alighting status A. Passenger boarding / alighting status C is a passenger boarding / alighting status in which there is a higher probability of a collision between boarding and alighting passengers when the doors open than in passenger boarding / alighting status B. In this embodiment, the control device 10 changes the display mode of the call button corresponding to a call depending on whether the passenger boarding / alighting status is A, B, or C.

[0123] Fig. 15 is a flowchart of the blinking determination process. As shown in Fig. 15, when the blinking determination process starts, the CPU 11 determines in S21 whether or not a wheelchair call is registered. For example, it determines whether or not a wheelchair call as described with reference to Fig. 12 is registered.

[0124] When the CPU 11 determines in S21 that a wheelchair call has been registered (YES in S21), the process proceeds to S24. On the other hand, when the CPU 11 does not determine in S21 that a wheelchair call has been registered (NO in S21), the process proceeds to S22.

[0125] In S22, the CPU 11 determines whether or not a predetermined motion of a passenger has been detected based on the image captured by the camera. For example, the CPU 11 determines whether or not a predetermined motion of a passenger (in this embodiment, a violent motion) as described with reference to FIG. 11 has been detected.

[0126] When the CPU 11 determines in S22 that the predetermined motion of the passenger has been detected based on the image captured by the camera (YES in S22), the process proceeds to S24. On the other hand, when the CPU 11 does not determine in S22 that the predetermined motion of the passenger has been detected based on the image captured by the camera (NO in S22), the process proceeds to S23.

[0127] In S23, the CPU 11 determines whether the number of people detected based on the image captured by the camera is equal to or greater than a predetermined number. For example, the CPU 11 determines whether the number of people detected based on the image captured by the camera as described with reference to FIG. 13 is equal to or greater than a predetermined number (five people in this embodiment).

[0128] If the CPU 11 determines in S23 that the number of people detected based on the image captured by the camera is equal to or greater than the predetermined number (YES in S23), the process proceeds to S24. On the other hand, if the CPU 11 does not determine in S23 that the number of people detected based on the image captured by the camera is equal to or greater than the predetermined number (NO in S23), the process ends. The CPU 11 sets the button to blink in S24, and ends the process.

[0129] In this embodiment, when it is determined that a wheelchair call has been registered (YES in S21), when it is determined that a predetermined passenger action has been detected (YES in S22), or when it is determined that the number of passengers is equal to or greater than a predetermined number (YES in S23), the call button corresponding to the registered call is made to flash. In other words, when none of the conditions in S21, S22, and S23 are met, the call button is made to light up, but when any of the conditions in S21, S22, and S23 are met, the call button is made to flash to better alert passengers getting on and off.

[0130] However, without being limited thereto, when any of the conditions S21, S22, and S23 is satisfied, the light may be lit with a higher brightness than when the conditions are not satisfied. When any of the conditions S21, S22, and S23 is satisfied, the light may be lit in a color different from when the conditions are not satisfied (for example, purple), or the color may be changed successively, such as red, purple, red, purple, etc., and any display mode may be used as long as it can better attract the attention of passengers getting on and off.

[0131] As described above, the information guidance system 1 in this embodiment is a system that provides information on passengers getting on and off an elevator. The information guidance system 1 includes a control device 10. The control device 10 controls the display mode of the call buttons. The call buttons include a car call button provided in the car, an upward platform call button provided at the platform, and a downward platform call button provided at the platform. When a call is registered from any of the car call button, the upward platform call button, and the downward platform call button, the control device 10 changes the display mode of the call button corresponding to the call depending on the passenger status when the door that is scheduled to open in response to the call opens.

[0132] In this way, the presence of passengers getting on and off can be known in advance. And since the call button pressed by the passenger is displayed in a different manner to inform the passenger, the possibility of a collision between passengers getting on and off can be intuitively understood. Also, by reusing the call button, there is no need to install a new information device, and manufacturing costs can be reduced. Furthermore, the possibility of a collision between passengers getting on and off can be known for each UP call button, DN call button, and car call button. Also, since the call buttons are lit in red, yellow, and blue in order of the likelihood of a collision, corresponding to the colors of the traffic lights, the possibility of a collision between passengers getting on and off can be more intuitively understood. This reduces collision accidents between passengers getting on and off and allows elevators to be used more safely.

[0133] In this embodiment, one car is installed in the building. However, the present invention is not limited to this, and multiple cars may be installed in the building. In this case, a control device 10 (individual car control device) may be installed for each car, and a group management control device may be provided to control each control device 10. In this case, the group management control device controls the hall devices collectively. The group management control device in this modified example corresponds to the control device 10 in this embodiment.

[0134] In the above, when a hall call button is pressed, the group management control device registers a hall call corresponding to the hall call button and assigns one of the multiple cars to the hall call. Furthermore, the group management control device determines the display mode of the hall call. The group management control device commands the assigned car to respond to the hall call, and changes the display mode of the corresponding hall call button to the determined display mode.

[0135] For example, in a building with two cars, car A and car B, assume that person C who boarded car A on the 4th floor registers a car call for the 1st floor, and person D at the boarding area on the 2nd floor registers a DN call. Also assume that car B is waiting on the 4th floor with no passengers.

[0136] Here, let us assume that the group management control device has assigned car A to the DN call on 2F. In this case, when car A opens its doors in response to the DN call on 2F, person D is a passenger planning to board, but person C heading to 1F is not a passenger planning to disembark (passenger boarding / alighting situation B). For this reason, the group management control device lights up the DN call button for 2F yellow. If there is no person at the 1F platform, it lights up car A's car call button for 1F blue.

[0137] Unlike the above, suppose the group management control device assigns car B to the DN call on 2F. In this case, when car B opens its door in response to the DN call on 2F, there is no person inside car B, so there is no possibility of a collision due to person D getting on (passenger boarding / alighting situation A). For this reason, the group management control device lights up the DN call button for 2F in blue. It lights up car A's car call button for 2F in red. In this way, when the group management control device controls multiple cars, the display mode of the call button may differ depending on the car to be assigned.

[0138] [Main components and effects] The main configurations and effects of the above-described embodiment will be described below.

[0139] (1) The information guidance system 1 is a system that provides information on passengers getting on and off an elevator. The information guidance system 1 includes call buttons and a control device 10. The control device 10 controls the display mode of the call buttons. The call buttons include a car call button provided in the car, an upward platform call button provided at the platform, and a downward platform call button provided at the platform. When a call is registered from any of the car call button, the upward platform call button, and the downward platform call button, the control device 10 changes the display mode of the call button corresponding to the call depending on the passenger status when the door that is scheduled to open in response to the call opens. This allows the possibility of a collision between passengers getting on and off to be intuitively grasped.

[0140] (2) The passenger boarding / alighting status includes a first passenger boarding / alighting status and a second passenger boarding / alighting status. The second passenger boarding / alighting status is a passenger boarding / alighting status in which there is a higher possibility of a collision between boarding and alighting passengers when the doors open than in the first passenger boarding / alighting status. The control device 10 changes the display mode of the call button corresponding to a call between the first passenger boarding / alighting status and the second passenger boarding / alighting status. This allows the possibility of a collision between boarding and alighting passengers to be intuitively grasped.

[0141] (3) The passenger boarding / alighting status includes a third passenger boarding / alighting status, a fourth passenger boarding / alighting status, and a fifth passenger boarding / alighting status. The third passenger boarding / alighting status is a passenger boarding / alighting status in which there are passengers planning to board and no passengers in the car when the door opens, or there are no passengers at the platform and there are passengers planning to disembark when the door opens. The fourth passenger boarding / alighting status is a passenger boarding / alighting status in which there are passengers planning to board and no passengers planning to disembark when the door opens, or there are people at the platform but no passengers planning to board and there are passengers planning to disembark in the car when the door opens. The fifth passenger boarding / alighting status is a passenger boarding / alighting status in which there are passengers planning to board and passengers planning to disembark when the door opens. The control device 10 changes the display mode of the call button corresponding to the call depending on whether the status is the third passenger boarding / alighting status, the fourth passenger boarding / alighting status, or the fifth passenger boarding / alighting status. This allows users to intuitively grasp the possibility of collisions between passengers getting on and off by dividing the situations into three categories: situations where there is no possibility of a collision between passengers getting on and off (safety), situations where there is a possibility of a collision if someone gets on or off by mistake (caution), and situations where there is a possibility of a collision between passengers getting on and off (danger).

[0142] (4) When the third passenger boarding / alighting situation occurs, the control device 10 lights up the call button corresponding to the call in blue. When the fourth passenger boarding / alighting situation occurs, the control device 10 lights up the call button corresponding to the call in yellow. When the fifth passenger boarding / alighting situation occurs, the control device 10 lights up the call button corresponding to the call in red. This allows the possibility of a collision to be grasped by using the same colors as traffic lights, so that the possibility of a collision between passengers can be more intuitively grasped.

[0143] (5) The control device 10 can detect a wheelchair call from a call button corresponding to a wheelchair. The control device 10 further changes the display mode of the call button corresponding to the call depending on whether the call includes a passenger who plans to board or disembark based on the wheelchair call or whether the call does not include a passenger who plans to board or disembark based on the wheelchair call. This makes it possible to alert the driver to the possibility of a collision with a passenger who plans to board or disembark based on the wheelchair call.

[0144] (6) The information guidance system 1 further includes cameras (120, 220, 320, 420, 520) capable of photographing the hall or the inside of the car. The control device 10 can detect a predetermined motion of a person based on the image photographed by the camera. The control device 10 further changes the display mode of the call button corresponding to the call depending on whether the predetermined motion is detected or not. This makes it possible to alert the user to the possibility of a collision with a passenger who may be acting violently inside the car.

[0145] (7) The information guidance method is a method for providing information on passengers getting on and off an elevator. The information guidance method includes a step of controlling a display mode of call buttons including a car call button provided in the car, an upward platform call button provided at the platform, and a downward platform call button provided at the platform. The controlling step includes a step of, when a call is registered from any of the car call button, the upward platform call button, and the downward platform call button, changing the display mode of the call button corresponding to the call depending on the passenger status when the door that is scheduled to open in response to the call opens. This allows the possibility of a collision between passengers getting on and off to be intuitively grasped.
