Description

[Technical Field]

[0001] The present disclosure relates to an elevator control system, an elevator, and an elevator car door control method. [Background technology]

[0002] Conventionally, when a car is waiting at a platform with its doors open, a control device is known that closes the car's doors, departs the platform, and moves to the floor specified by a destination floor call when a passenger inside the car operates the door-close button on an operating device inside the car or when the maximum door-open time limit has elapsed (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2017-030918 Summary of the Invention [Problem to be solved by the invention]

[0004] With conventional control devices, even if there are passengers at the landing who want to board the car, if a passenger in the car presses the door close button, the doors will close, preventing the passengers at the landing from boarding. On the other hand, if the control is set to always wait until the maximum door opening time has elapsed before closing the doors, passengers in the car may have to wait until the maximum door opening time has elapsed even if there are no new passengers. In either case, there is a problem in that it is not possible to further improve the convenience of elevators.

[0005] In order to solve the above problems, the present disclosure aims to provide an elevator control system, an elevator, and an elevator car door control method that can further improve the convenience of elevators. [Means for solving the problem]

[0006] The elevator control system according to the present disclosure includes a control device capable of controlling the opening and closing of the elevator car doors, and the control device is capable of generating call registrations corresponding to each passenger using the elevator, each of which includes information on the boarding floor at which the passenger who registered the call registration will board the car, and the control device is capable of stopping the car at the specific boarding floor included in the call registration and opening the car doors, and the control device is capable of comparing the number of boarding passengers who board the car from the specific boarding floor with the number of call registrations including information on the boarding floor that matches the specific boarding floor, and checking whether the car doors at the specific boarding floor have remained open for a certain period of time, and the control device is capable of closing the car doors either when it determines that the number of boarding passengers is equal to or greater than the number of call registrations including information on the boarding floor that matches the specific boarding floor, or when it determines that the car doors have remained open for a certain period of time at the specific boarding floor.

[0007] An elevator according to the present disclosure includes the elevator control system according to the present disclosure, a car having car doors, and a hoist that moves the car.

[0008] The elevator car door control method according to the present disclosure includes, in an elevator control system according to the present disclosure, a boarding floor stopping step in which a control device stops the car at a specific boarding floor based on a specific boarding floor and opens the car doors; a boarding floor number confirmation step in which, after the boarding floor stopping step, the control device compares the number of boarding passengers with the number of call registrations including boarding floor information that matches the specific boarding floor; a car open time confirmation step in which, after the boarding floor stopping step, the control device confirms whether the car doors have remained open for a certain period of time; and a car door closing step in which the control device closes the car doors. The car door closing step is performed either when, in the boarding passenger number confirmation step, the control device determines that the number of boarding passengers is equal to or greater than the number of call registrations including boarding floor information that matches the specific boarding floor, or when, in the car open time confirmation step, the control device determines that the car doors have remained open for a certain period of time.

DETAILED DESCRIPTION OF THE INVENTION

[0011] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. Embodiment 1 1 is a schematic diagram showing a control system 1 for an elevator 101 according to embodiment 1. One elevator 101 is installed inside a building 200 having multiple floors.

[0012] A vertically extending elevator shaft 201 is installed in a building 200. Landing places 202 are installed on specific floors of the building 200. Each landing place 202 is formed with an entrance (not shown) that leads to the elevator shaft 201. Each landing place 202 is installed with an entrance door (not shown) that can close the entrance.

[0013] The car 102 and the counterweight 103 are movable in the vertical direction along a hoistway 201 installed in a building 200. The car 102 and the counterweight 103 will be described later.

[0014] The elevator 101 comprises one car 102, a lifting weight 103, a main rope 104 to which the car 102 and the lifting weight 103 are connected at both ends, a hoist 105 around which the main rope 104 is wound, a control device 107 for controlling the hoist 105, and one or more information terminals 110 carried by passengers who use the elevator 101 as call request generating devices.

[0015] Passengers can ride inside the car 102. Figure 2 is a schematic diagram showing the inside of the car 102 of Figure 1.

[0016] The car 102 has a car body 102a, a car door 102b that can close the passageway opened in the car body 102a, and a first door closing button 102c and a second door closing button 102d installed inside the car body 102a.

[0017] Returning to Figure 1, the explanation will continue. The hoisting machine 105 and the control device 107 are installed at the top of the hoistway 201. When the hoisting machine 105 rotates, the car 102 connected to the main rope 104 moves. In more detail, the hoisting machine 105 is provided with a main sheave (not shown) that rotates together with the rotating shaft, and the main rope 104 is wound around the main sheave.

[0018] The control device 107 is electrically connected to a plurality of sensors that detect various states of the elevator 101 and an operating device, and is capable of inputting and outputting signals to and from each of the sensors and operating devices. The operating device also includes a first door close button 102c and a second door close button 102d.

[0019] The first door close button 102c and the second door close button 102d can output a signal indicating that they are being pressed to the control device 107.

[0020] One or more information terminals 110 are wirelessly connected to the control device 107 so that information can be communicated between them. The control device 107 can generate call registrations based on information input from each of the information terminals 110.

[0021] A call registration is generated in response to a request for operation of the car 102 input from each of the information terminals 110. A request for operation of the car 102 input from each of the information terminals 110 is referred to as a call request. Call requests will be explained later.

[0022] The control device 107 can control the movement of the car 102 and the opening and closing operation of the car door 102b based on the call registration. One call registration includes boarding floor information, which is the floor at which a passenger holding the information terminal 110 that generated the call request that is the basis of the call registration will board the car 102, and destination floor information, which is the floor at which the corresponding passenger will disembark from the car 102.

[0023] Based on the call registration, the control device 107 can move the car 102 to a specific boarding floor included in the specific call registration and stop the car 102. After that, the control device 107 can open the car door 102b of the stopped car 102.

[0024] Thereafter, the control device 107 closes the open car door 102b, moves the car 102 to the destination floor, stops the car 102 at the destination floor again, and opens the car door 102b of the car 102 that has stopped at the destination floor.

[0025] The control device 107 can execute the movement of the car 102 and the control of the car door 102b based on a plurality of call registrations. That is, the control device 107 can execute the movement of the car 102 and the control of the car door 102b based on a plurality of call requests.

[0026] The call request generation device can generate a call request corresponding to each passenger. In the first embodiment, the call request generation device is one or more information terminals 110 carried by each passenger. Specifically, the information terminals 110 are smartphones owned by the passengers.

[0027] In order to use the elevator 101, a dedicated app must be installed in advance on the smartphone. When the app is launched, the smartphone functions as an information terminal 110. Note that the information terminal 110 may be lent to the passenger by a person who manages the elevator 101.

[0028] The information terminal 110 on which the application is activated can grasp the destination floor, which is the floor to which the passenger wants to go using the elevator 101. In this case, the passenger sets the destination floor by operating the application.

[0029] The information terminal 110 can grasp its own position using an acceleration sensor and a GPS system installed in the information terminal 110. In other words, the information terminal 110 can grasp which floor of the building 200 the passenger carrying the information terminal 110 is on.

[0030] The information terminal 110 generates a call request with the set destination floor and the floor where the information terminal 110 itself is located as the boarding floor. In other words, the boarding floor indicates the floor where the passenger carrying the information terminal 110 will board the car 102. The information terminal 110 can transmit the generated call request to the control device 107.

[0031] The control device 107 generates call registrations based on the call requests as described above, i.e., the control device 107 can generate a call registration corresponding to each passenger using the elevator 101.

[0032] The control system 1 includes a control device 107 of the elevator 101, two door close buttons installed in the car 102, a first door close button 102c and a second door close button 102d, and one or more information terminals 110. In other words, the control system 1 is included in the elevator 101, and the devices that make up the control system 1 are the devices that make up the elevator 101.

[0033] 3 is a flowchart showing a method for controlling car door 102b after stopping at a boarding floor according to Embodiment 1. Control of car door 102b at a boarding floor will be described below with reference to FIG.

[0034] <Call registration generation process> In step S01, a call registration generation step is performed in which the control device 107 generates a call registration based on each call request sent from the information terminal 110.

[0035] A passenger starts an application on the information terminal 110 that the passenger carries with them, and prepares to use the elevator 101. When the application starts, the information terminal 110 determines its own current location and determines which floor of the building 200 the information terminal 110 is on.

[0036] The passenger sets the destination floor by operating the application on the information terminal 110. The information terminal 110 recognizes the current floor where the information terminal 110 itself is located as the boarding floor. After identifying the boarding floor and the destination floor, the information terminal 110 transmits a call request to the control device 107.

[0037] Upon receiving the call request, the control device 107 generates a call registration based on the call request, and the process of step S01 is now complete. <Departure floor stop process> In step S02, a boarding floor stopping process is performed. The boarding floor stopping process is a process in which the control device 107 moves and stops the car 102 based on the call registration, and the car door 102b is opened.

[0038] Based on the specific call registration, the control device 107 moves the car 102 to a specific boarding floor included in the specific call registration and stops the car 102. When the car 102 stops at the boarding floor, the control device 107 opens the car door 102b. This ends the processing of step S02. After step S02, the processing of steps S03 and S04 is executed simultaneously.

[0039] <Process for checking the number of boarding passengers> In step S03, a boarding passenger number confirmation step is performed. In the boarding passenger number confirmation step, the control device 107 compares the number of passengers who boarded the car 102 at the corresponding boarding floor with the number of call registrations having the corresponding boarding floor. Here, passengers who boarded the car 102 at the corresponding boarding floor are defined as boarding passengers.

[0040] The control device 107 generates call registrations based on call requests sent by the information terminals 110 carried by passengers. That is, at a particular boarding floor where the car 102 stops, the number of call registrations having corresponding boarding floor information is the number of passengers who are expected to board the car 102 from that boarding floor.

[0041] Therefore, by knowing the number of boarding passengers, it is possible to confirm whether all passengers who wish to use the elevator 101 at the corresponding boarding floor have boarded the car 102. That is, in the boarding passenger number confirmation process, it is possible to confirm whether all passengers have boarded the car 102.

[0042] Specifically, the control device 107 determines whether a signal indicating that the first door close button 102c installed in the car 102 is pressed and a signal indicating that the second door close button 102d is pressed are simultaneously input at a specific moment. This makes it possible to grasp the number of passengers on board.

[0043] When two door close buttons are pressed at the same time at a specific moment, the control device 107 recognizes that there are two passengers on board. In this case, the two passengers must each press one door close button.

[0044] When the control device 107 determines that there are two call registrations including the information of the corresponding boarding floor and that there are two boarding passengers, it determines that all passengers who have issued call requests have boarded the car 102. This ends step S03, and the process proceeds to step S10.

[0045] In the above case, the number of call registrations containing the relevant boarding floor information is two, but even if there is only one call registration containing the relevant boarding floor information, the control device 107 can determine that all passengers who have made call requests have boarded the car 102.

[0046] Specifically, when only one of the first door close button 102c and the second door close button 102d is pressed, the control device 107 determines that there is one boarding passenger. When the control device 107 determines that there is one call registration including the information of the corresponding boarding floor and that there is one boarding passenger, it determines that all passengers who have issued call requests have boarded the car 102. This ends step S03, and the process proceeds to step S10.

[0047] That is, when the number of boarding passengers at a specific boarding floor is equal to or greater than the number of call registrations containing boarding floor information that matches the boarding floor, the control device 107 determines that all passengers who have issued call requests at that boarding floor have boarded the car 102. This ends step S03, and the process proceeds to step S10.

[0048] On the other hand, even if the control device 107 determines that there is one passenger on board because, for example, only one of the first door close button 102c and the second door close button 102d has been pressed, if there are two or more call registrations including the information of the corresponding boarding floor, the control device 107 determines that all passengers who have issued call requests at that boarding floor are not on the car 102. In this case, the process does not proceed to step S10, but returns to step S03 again.

[0049] Furthermore, in the first embodiment, since there are only two door close buttons, the first door close button 102c and the second door close button 102d, the control device 107 cannot know that there are three or more boarding passengers. Therefore, when there are three or more call registrations including the boarding floor information, the control device 107 determines that all passengers who have issued call requests at that boarding floor have not boarded the car 102. In this case as well, the process does not proceed to step S10, but returns to step S03 again.

[0050] That is, if the number of boarding passengers at a specific boarding floor is less than the number of call registrations containing boarding floor information that matches the boarding floor, the control device 107 determines that all passengers who have issued call requests at that boarding floor are not boarding the car 102. As a result, the process returns to step S03 again.

[0051] <Cage opening time confirmation process> In step S04, a car open time confirmation process is performed. The car open time confirmation process is a process in which the control device 107 confirms whether the car door 102b of the car 102 stopped at the corresponding boarding floor has been open for a certain period of time.

[0052] The control device 107 confirms that the car 102 has stopped at the boarding floor and that the car door 102b is fully open, and then starts measuring time. When this time reaches a certain time, for example, 60 seconds, the control device 107 determines that the car door 102b has remained open for the certain time. This ends step S04, and the process proceeds to step S10.

[0053] On the other hand, if the car door 102b is open and the certain time has not yet elapsed, the process returns to step S04.

[0054] <Cage door closing process> In step S10, a car door closing process is carried out. The car door closing process is a process in which the control device 107 closes the car door 102b.

[0055] The control device 107 closes the car door 102b. As a result, the car door 102b is closed at the boarding floor. After the car door 102b is closed, the control device 107 moves the car 102 to the nearest new boarding floor or destination floor in the direction of movement of the car, based on the call registration.

[0056] Steps S03 and S04 are repeatedly performed unless the process proceeds to step S10.

[0057] In this way, by making the judgments in steps S03 and S04, if the control device 107 determines that all passengers who have issued call requests including information on the corresponding boarding floor are not on the car 102, it keeps the car door 102b open for a certain period of time, i.e., 60 seconds.

[0058] On the other hand, if the control device 107 determines that all passengers who have submitted call requests including information on the corresponding boarding floor have boarded the car 102, the control device 107 closes the car door 102b before a certain period of time has elapsed.

[0059] In other words, the control device 107 can close the car door 102b in either case where it determines that the number of boarding passengers is equal to or greater than the number of call registrations containing boarding floor information that matches the specific boarding floor, or where it determines that the car door 102b has remained open at the specific boarding floor for a certain period of time.

[0060] The control system 1 in the first embodiment is equipped with a first door close button 102c and a second door close button 102d. However, this is not limited to this. For example, the control system 1 may be equipped with only one door close button. In this case, the control device 107 can only grasp the number of boarding passengers up to one.

[0061] Furthermore, the control system 1 in the first embodiment uses the first door close button 102c and the second door close button 102d to grasp the number of boarding passengers. However, this is not limited to this. The number of boarding passengers may be grasped using a button other than the door close button.

[0062] The control system 1 for an elevator 101 according to the first embodiment includes a control device 107 that can control the opening and closing operation of the car door 102b of the car 102 of the elevator 101. The control device 107 can also generate a call registration corresponding to each passenger using the elevator 101, and each call registration includes information on the boarding floor at which the passenger who registered the call registration boards the car 102. The control device 107 can also stop the car 102 at a specific boarding floor included in the call registration and open the car door 102b. The control device 107 can also compare the number of boarding passengers who board the car 102 from a specific boarding floor with the number of call registrations that include boarding floor information that matches the specific boarding floor, and can check whether the car door 102b has been open at the specific boarding floor for a certain period of time. Furthermore, the control device 107 can close the car door 102b when it determines that the number of boarding passengers is equal to or greater than the number of call registrations containing boarding floor information that matches the specific boarding floor, or when it determines that the car door 102b has remained open at the specific boarding floor for a certain period of time. This allows each passenger who has generated a call request to board the car 102, and when all passengers who have generated call requests are in the car 102, the car door 102b can be closed. This can further improve the convenience of the elevator. This can also further improve the operating efficiency of the elevator 101.

[0063] The control system 1 of the elevator 101 according to the first embodiment further includes one or more door close buttons installed inside the car 102, and each door close button can output a signal indicating that the door close button itself is pressed to the control device 107. Based on this signal, the control device 107 can determine the number of door close buttons pressed at any given moment as the number of boarding passengers. This allows the control device 107 to determine the number of boarding passengers using the door close buttons. Therefore, the car doors 102b can be closed using the button that passengers normally use. This further improves the convenience of the elevator.

[0064] The control system 1 for the elevator 101 according to the first embodiment further includes one or more information terminals 110 carried by passengers. Each information terminal 110 can grasp its own location. Each information terminal 110 can recognize the floor where the information terminal 110 is located as the boarding floor and the floor input by the passenger as the destination floor, and generate a call request including information on the boarding floor and the destination floor. Each information terminal 110 can transmit the generated call request to the control device 107, which can generate a corresponding call registration based on each received call request. This allows the control device 107 to generate a call registration based on the call request generated by the information terminal 110. By generating one call registration for each passenger carrying an information terminal 110, the control device 107 can accurately grasp the number of passengers waiting for the car 102 at the boarding floor. This allows the control device 107 to accurately compare the number of boarding passengers with the number of call registrations including boarding floor information that matches a specific boarding floor, enabling more accurate control.

[0065] The elevator 101 according to the first embodiment includes the control system 1 of the present disclosure and a car 102 having a car door 102b. As a result, each passenger who has generated a call request can board the car 102, and when all passengers who have generated call requests are in the car 102, the car door 102b can be closed. This further improves the convenience of the elevator.

[0066] The control method for the car door 102b of the elevator 101 according to the first embodiment includes a boarding floor stopping step in which the control device 107 stops the car 102 at a specific boarding floor and opens the car door 102b based on a specific boarding floor registration in the control system 1 of the present disclosure. After the boarding floor stopping step, the control device 107 also includes a boarding passenger count confirmation step in which the control device 107 compares the number of boarding passengers with the number of call registrations containing boarding floor information that matches the specific boarding floor. After the boarding floor stopping step, the control device 107 also includes a car open time confirmation step in which the control device 107 confirms whether the car door 102b has remained open for a certain period of time. The control device 107 also includes a car door closing step in which the control device 107 closes the car door 102b. The car door closing process is performed when the control device 107 determines in the boarding passenger number confirmation process that the number of boarding passengers is equal to or greater than the number of call registrations containing boarding floor information that matches the specific boarding floor, or when the control device 107 determines in the car open time confirmation process that the car door 102b has been open for a certain period of time. This allows each passenger who has generated a call request to board the car 102, and when all passengers who have generated call requests are in the car 102, the car door 102b can be closed. This further improves the convenience of the elevator.

[0067] Embodiment 2 The second embodiment differs from the first embodiment, which uses the first door close button 102c and the second door close button 102d to determine the number of passengers, in that the second embodiment uses the imaging device 120 installed in the car 102 to determine the number of passengers on board.

[0068] 4 is a schematic diagram showing the inside of the car 102 according to the second embodiment. The control system 1 further includes an imaging device 120 installed in the car 102. The imaging device 120 is capable of capturing images of the inside of the car 102. The imaging device 120 is connected to the control device 107 so as to be able to communicate information with the control device 107.

[0069] The imaging device 120 constantly outputs the captured image to the control device 107. The control device 107 analyzes the input image and can ascertain the number of passengers on board.

[0070] The imaging device 120 has a camera that can capture images using natural light, a thermo camera that captures images using infrared light, or other cameras that can detect the presence of a person. The other configurations of the control system 1 of the second embodiment are the same as those of the control system 1 of the first embodiment, and therefore a description of the other configurations will be omitted.

[0071] The control system 1 for the elevator 101 according to the second embodiment further includes an imaging device 120 installed inside the car 102. The imaging device 120 can output an image of the interior of the car 102 to the control device 107. The control device 107 can also determine the number of passengers by analyzing the image. This allows the car doors 102b to close within a certain time period without relying on the passengers' judgment. This further improves the convenience of the elevator.

[0072] Embodiment 3 The third embodiment differs from the first embodiment, which uses the first door close button 102c and the second door close button 102d to determine the number of passengers, in that it uses a weight measuring device 125 installed in the car 102 to determine the number of passengers on board.

[0073] 5 is a schematic diagram showing a car 102 according to the third embodiment. The control system 1 further includes a weight measuring device 125 installed in the car 102. The weight measuring device 125 can measure the weight of the car 102 and the weight of passengers inside the car 102. The weight measuring device 125 is connected to the control device 107 so as to be able to communicate information with it.

[0074] The weight measuring device 125 constantly outputs the measured weight to the control device 107. The control device 107 can grasp the number of passengers who have boarded the car 102 based on the increase in the input weight.

[0075] The number of boarding passengers due to the increase in weight of the car 102 can be determined based on the average weight of an adult. Alternatively, the weight of the passengers using the information terminal 110 is registered in each information terminal 110, and the weight information is included in the call request, allowing the control device 107 to determine the weight of each corresponding passenger. The control device 107 may also be configured to determine the number of boarding passengers based on the weight of each passenger and the increase in weight of the car 102.

[0076] Alternatively, the gender and age of the passenger using the information terminal 110 are registered in each information terminal 110, and the gender and age information is included in the call request, allowing the control device 107 to know the standard weight of each corresponding passenger based on their gender and age. The control device 107 may also be configured to know the number of passengers on board based on the standard weight corresponding to each passenger and the increase in weight of the car 102. The other configurations of the control system 1 of the third embodiment are similar to those of the control system 1 of the first embodiment, and therefore description of the other configurations will be omitted.

[0077] The control system 1 for the elevator 101 according to the third embodiment further includes a weight measuring device 125 that is installed in the car 102 and can measure the weight of the car 102. The weight measuring device 125 can output the weight to the control device 107, and the control device 107 can determine the number of passengers on board based on the weight. This allows the car door 102b to close within a certain time period without relying on the passengers' judgment. This further improves the convenience of the elevator.

[0078] Embodiment 4 Embodiment 4 differs from embodiment 1, which uses the first door close button 102c and the second door close button 102d to determine the number of passengers on board, in that it uses the air flow measuring device 130 installed in the car 102 to determine the number of passengers on board.

[0079] 6 is a schematic diagram showing the inside of the car 102 according to the fourth embodiment. The control system 1 further includes an air flow measuring device 130 installed in the car 102. The air flow measuring device 130 can measure the air flow rate inside the car 102.

[0080] For example, as shown in Fig. 6, the air flow measuring devices 130 are installed between the inner wall and outer wall (not shown) of the car 102, and are installed in pairs on either side of the opening of the car 102. The air flow measuring devices 130 are connected to the control device 107 so as to be able to communicate information.

[0081] When a passenger gets on the car 102, wind is generated by the movement of the passenger. That is, the airflow measuring device 130 can measure the volume of wind generated when a passenger gets on the car 102 with the car door 102b open.

[0082] The airflow measuring device 130 constantly outputs the measured airflow to the control device 107. The control device 107 can grasp the number of passengers on board from fluctuations in the input airflow. The other configurations of the control system 1 of the fourth embodiment are the same as the other configurations of the control system 1 of the first embodiment, and therefore a description of the other configurations will be omitted.

[0083] The control system 1 for the elevator 101 according to the fourth embodiment further includes an airflow measuring device 130 that is installed in the car 102 and that can measure the airflow when passengers board the car 102 with the car doors 102b open. The airflow measuring device 130 can output the airflow to the control device 107, and the control device 107 can determine the number of passengers on board based on the airflow. This allows the car doors 102b to be closed within a certain time period without relying on the passengers' judgment. This further improves the convenience of the elevator.

[0084] Embodiment 5 Embodiment 5 differs from embodiment 1, which uses the first door close button 102c and the second door close button 102d to determine the number of passengers, in that it uses a human presence sensor 135 installed in the car 102 to determine the number of passengers on board.

[0085] 7 is a schematic diagram showing the inside of the car 102 according to the fifth embodiment. The control system 1 further includes a human presence sensor 135 installed in the car 102. The human presence sensor 135 can detect passengers who have boarded the car 102. The human presence sensor 135 is disposed in a position where it can detect passengers who have boarded the car 102. The human presence sensor 135 is connected to the control device 107 so as to be able to communicate information with the control device 107.

[0086] When the human presence sensor 135 detects a moving object such as a person, it outputs a signal indicating that it has been detected. This signal is constantly input to the control device 107. The control device 107 can determine the number of passengers on board from the input signal. The other configurations of the control system 1 of the fifth embodiment are the same as the other configurations of the control system 1 of the first embodiment, and therefore a description of the other configurations will be omitted.

[0087] The control system 1 for the elevator 101 according to the fifth embodiment further includes a human presence sensor 135 capable of detecting passengers in the car 102, and the human presence sensor 135 can output a signal indicating that a passenger has been detected to the control device 107. The control device 107 can also grasp the number of passengers on the basis of the signal. This allows the car door 102b to close within a certain time period without relying on the passengers' judgment. This further improves the convenience of the elevator.

[0088] Embodiment 6 Embodiment 6 differs from embodiment 1, which uses the first door close button 102c and the second door close button 102d to determine the number of passengers on board, in that it uses a foot detection device 140 installed on the floor of the car 102 in a certain area from the car door 102b toward the inside of the car 102 to determine the number of passengers on board.

[0089] 8 is a schematic diagram showing the inside of the car 102 according to the sixth embodiment. The control system 1 further includes a step-in detection device 140 installed on the floor of the car 102 in a certain area extending from the car door 102b toward the inside of the car 102. The step-in detection device 140 is connected to the control device 107 so as to be able to communicate information with it.

[0090] The stepping detection device 140 detects that a passenger steps on the floor when getting on the car 102, and outputs a signal indicating this to the control device 107.

[0091] The step-in detection device 140 is for detecting passengers who have boarded the car 102, and is therefore installed on the floor of the car 102 in a certain area extending from the car door 102b toward the inside of the car 102. The certain area extending from the car door 102b toward the inside of the car 102 may be, for example, an area extending one or two adult strides from the car door 102b.

[0092] The step-on detection device 140 may be installed over the entire surface of the floor inside the car 102. In that case, the entire floor surface may be divided into a plurality of areas, and a signal indicating that the floor has been stepped on may be output for each of these areas. The step-on detection device 140 may employ a well-known configuration such as a piezoelectric sensor or a step-on switch.

[0093] The control device 107 can grasp the number of boarding passengers from the input signal. Other configurations of the control system 1 of the sixth embodiment are similar to other configurations of the control system 1 of the first embodiment, and therefore description of the other configurations will be omitted.

[0094] The control system 1 of the elevator 101 according to the sixth embodiment further includes a step-in detection device 140 installed on the floor of the car 102 in a certain area extending from the car door 102b toward the inside of the car 102. The step-in detection device 140 can detect that a passenger has stepped on the certain area extending from the car door 102b toward the inside of the car 102. The step-in detection device 140 can output a signal to the control device 107 indicating that a passenger has stepped on the certain area. The control device 107 can also grasp the number of passengers on the basis of the signal. This allows the car door 102b to close within a certain time period without relying on the passengers' judgment. This further improves the convenience of the elevator.

[0095] Embodiment 7 Embodiment 7 differs from embodiment 1, which uses the first door close button 102c and the second door close button 102d to determine the number of passengers on board, in that it uses a confirmation switch 145 that is installed inside the car 102 and can be pressed or touched by passengers to determine the number of passengers on board.

[0096] FIG. 9 is a schematic diagram showing the inside of a car 102 according to the seventh embodiment. The control system 1 further includes a confirmation switch 145 installed in the car 102. One confirmation switch 145 is arranged in the car 102. Note that two or more confirmation switches 145 may be arranged in the car 102.

[0097] The confirmation switch 145 is connected to the control device 107 so as to be able to communicate with the control device 107. The confirmation switch 145 can output a signal indicating that it has been pressed or touched by a passenger. The signal output by the confirmation switch 145 is constantly input to the control device 107.

[0098] In the seventh embodiment, each passenger presses or touches the confirmation switch 145 when getting on the car 102. This allows the control device 107 to count the signals input from the confirmation switch 145, thereby determining the number of passengers on board.

[0099] A dedicated switch may be installed as the confirmation switch 145, or a switch required for operating the existing elevator 101 may also be used. The other configurations of the control system 1 of the seventh embodiment are the same as the other configurations of the control system 1 of the first embodiment, and therefore a description of the other configurations will be omitted.

[0100] The control system 1 for the elevator 101 according to the seventh embodiment further includes a confirmation switch 145 installed in the car 102, and the confirmation switch 145 can output a signal indicating that it has been pressed or touched to the control device 107. The control device 107 can also determine the number of passengers by counting the signals. This allows passengers who board the car 102 to press the confirmation switch 145 themselves. This allows the control device 107 to more reliably determine the number of passengers. Therefore, by accurately determining the number of passengers, the car doors 102b can be closed accurately when necessary, further improving the convenience of the elevator.

[0101] Embodiment 8 Embodiment 8 differs from embodiment 1, which uses the first door close button 102c and the second door close button 102d to determine the number of passengers on board, in that it uses a voice recognition device 150 that is installed in the car 102 and can recognize the voices made by passengers to indicate that they have boarded the car, to determine the number of passengers on board.

[0102] 10 is a schematic diagram showing the inside of the car 102 according to the eighth embodiment. The control system 1 further includes a voice recognition device 150 installed in the car 102. The voice recognition device 150 is connected to the control device 107 so as to be able to communicate information with it.

[0103] The voice recognition device 150 can recognize the words of passengers who have boarded the car 102. Furthermore, when the voice recognition device 150 recognizes the voice of a passenger indicating that he or she has boarded, it can output a signal to the control device 107 indicating that the passenger has boarded.

[0104] For example, when a passenger gets on the car 102, the passenger himself / herself utters, "I'm on board." When the voice recognition device 150 recognizes this voice, it outputs a signal indicating that the passenger has boarded. Therefore, the control device 107 can grasp the number of passengers on board by counting the signals.

[0105] The voice recognition device 150 itself may count the number of boarding passengers at a specific boarding floor and output the counted value to the control device 107. This allows the control device 107 to grasp the number of boarding passengers themselves from the input signal.

[0106] In this case, a signal indicating that the car door 102b is closed may be output from the control device 107 to the voice recognition device 150, and the counted value may be cleared to zero by the signal. The other configurations of the control system 1 of the eighth embodiment are the same as the other configurations of the control system 1 of the first embodiment, and therefore a description of the other configurations will be omitted.

[0107] The control system 1 for the elevator 101 according to the eighth embodiment further includes a voice recognition device 150 that is installed in the car 102 and that can recognize the voices made by passengers to indicate that they have boarded the elevator. The voice recognition device 150 can recognize the voices made by passengers to indicate that they have boarded the elevator and output a signal indicating that the passengers have boarded the elevator to the control device 107. The control device 107 can also determine the number of passengers who have boarded the elevator based on the signal. This allows the passengers who have boarded the elevator to themselves speak. Therefore, the control device 107 can more reliably determine the number of passengers who have boarded the elevator. Therefore, by accurately determining the number of passengers who have boarded the elevator, the car doors 102b can be closed accurately when necessary, further improving the convenience of the elevator.

[0108] Embodiment 9 Embodiment 9 differs from embodiment 1, which uses first door close button 102c and second door close button 102d to determine the number of passengers on board, in that it uses an alarm device 155 that can notify information inside the car to determine the number of passengers on board, and a boarding confirmation switch 156 that can output a signal indicating that it has been pressed by a passenger.

[0109] 11 is a schematic diagram showing the inside of a car 102 according to embodiment 9. The control system 1 further includes an alarm device 155 installed in the car 102 and a boarding confirmation switch 156 installed in the car 102.

[0110] The notification device 155 and the boarding confirmation switch 156 are each connected to the control device 107 so as to be able to communicate information. The notification device 155 can notify information inside the car 102 based on a signal output from the control device 107. The notification device 155 is a display device.

[0111] The boarding confirmation switch 156 can output a signal indicating that it is pressed. The signal output by the boarding confirmation switch 156 is constantly input to the control device 107.

[0112] The control device 107 stops the car 102 at the boarding floor corresponding to the call registration and opens the car door 102b, and then uses the notification device 155 to notify the number of call registrations that include information about boarding floors that match the boarding floor. Specifically, the number of call registrations is displayed on the display device that is the notification device 155.

[0113] If the number of passengers in the car 102 reaches or exceeds the number notified by the notification device 155, the passengers in the car 102 press the boarding confirmation switch 156 at their own discretion.

[0114] When the boarding confirmation switch 156 is pressed, a signal is input from the boarding confirmation switch 156 to the control device 107. When this signal is input, the control device 107 determines that the number of boarding passengers is equal to or greater than the number of call registrations containing boarding floor information that matches the boarding floor. This allows the control device 107 to close the car door 102b without waiting for a certain period of time.

[0115] A dedicated switch may be installed as the boarding confirmation switch 156, or a switch required for operating an existing elevator 101 may also function as the boarding confirmation switch 156. The other configurations of the control system 1 of the ninth embodiment are the same as the other configurations of the control system 1 of the first embodiment, and therefore a description of the other configurations will be omitted.

[0116] The notification device 155 in the ninth embodiment is a display device. However, the present invention is not limited to this. For example, a speaker may be used as the notification device 155. In this case, the number of registered calls is announced from the speaker.

[0117] The control system 1 for the elevator 101 according to the ninth embodiment further includes an alarm device 155 installed in the car 102 and a boarding confirmation switch 156 installed in the car 102. The control device 107 can use the alarm device 155 to notify the car of the number of call registrations containing boarding floor information matching the specific boarding floor. The boarding confirmation switch 156 can output a signal indicating that it has been pressed by a passenger to the control device 107. Upon receiving this signal, the control device 107 determines that the number of boarding passengers is equal to or greater than the number of call registrations containing boarding floor information matching the specific boarding floor, and can close the car door 102b. This allows the passengers who board the car 102 to determine that the number of boarding passengers is equal to or greater than the number of call registrations containing boarding floor information matching the specific boarding floor. This allows the control device 107 to more reliably grasp the number of boarding passengers. By accurately grasping the number of boarding passengers, the control device 107 can accurately close the car door 102b when necessary, further improving the convenience of the elevator.

[0118] Embodiment 10 Embodiment 10 differs from embodiment 1, which uses the first door close button 102c and the second door close button 102d to determine the number of boarding passengers, in that embodiment 10 uses one or more boarding hall imaging devices 160 installed at each boarding hall 202 to determine the number of boarding passengers.

[0119] 12 is a schematic diagram showing a platform 202 according to the tenth embodiment. The control system 1 further includes one or more platform imaging devices 160 installed at each platform 202. Each platform imaging device 160 is installed in a position where it can capture an image of the car 102 from the platform 202.

[0120] Each landing image capturing device 160 is connected to the control device 107 so as to be able to communicate information. Each landing image capturing device 160 constantly outputs an image of the car 102 seen from the corresponding landing 202 to the control device 107. The control device 107 analyzes the input image to identify passengers boarding the car 102 from the corresponding landing 202, and is able to identify the number of boarding passengers.

[0121] The hall imaging device 160 has a camera that can detect the presence of a person, such as a camera that can take pictures using natural light and a thermo camera that takes pictures using infrared light, etc. The other configurations of the control system 1 of the tenth embodiment are the same as the other configurations of the control system 1 of the first embodiment, and therefore a description of the other configurations will be omitted.

[0122] The control system 1 for the elevator 101 according to the tenth embodiment further includes one or more hall image capture devices 160 installed at each hall 202, and each hall image capture device 160 can capture an image of the car 102 from the corresponding hall 202. Each hall image capture device 160 can output the image of the car 102 captured by the hall image capture device 160 as seen from the corresponding hall 202 to the control device 107. The control device 107 can analyze the image to identify passengers who have boarded the car 102 from the corresponding hall 202 and determine the number of boarded passengers. This allows the car door 102b to close within a certain time period without relying on the passengers' judgment. This further improves the convenience of the elevator.

[0123] Variation 1 of the 10th embodiment Variant 1 of embodiment 10 differs from embodiment 10 in that the platform imaging device 160 is used to check whether there are passengers at the platform 202, in that it is used to identify passengers who have boarded the car 102 from the platform 202.

[0124] An explanation will be given based on Fig. 12. The hall imaging device 160 is installed in a position where it can capture an image of the entire hall 202. The hall imaging device 160 constantly outputs an image of the entire hall 202 to the control device 107. The control device 107 analyzes the input image and can determine that there are no passengers in the elevator 101 at the hall 202.

[0125] When the control device 107 determines that there are no passengers in the elevator 101 at the hall 202, it can determine that all passengers at that hall who generated call requests have boarded the car 102. Therefore, the control device 107 determines that the number of boarding passengers is equal to or greater than the number of call registrations that include boarding floor information that matches the specific boarding floor. The other configurations of the control system 1 of the first modified example of the tenth embodiment are the same as the other configurations of the control system 1 of the tenth embodiment, and therefore a description of the other configurations will be omitted.

[0126] The control system 1 for the elevator 101 according to the first modification of the tenth embodiment further includes one or more landing image capture devices 160 installed at each landing 202, and each landing image capture device 160 is capable of capturing an image of the corresponding landing 202. Each landing image capture device 160 is capable of outputting the image of the corresponding landing 202 captured by the device to the control device 107. The control device 107 analyzes the image and, if there are no passengers at the landing 202 at the corresponding boarding floor, determines that the number of boarding passengers is equal to or greater than the number of registered calls containing boarding floor information that matches the corresponding boarding floor, and can close the car door 102b. This allows the car door 102b to be closed within a certain period of time without relying on the passengers' judgment. This further improves the convenience of the elevator.

[0127] Embodiment 11 Embodiment 11 differs from embodiment 1, which uses the first door close button 102c and the second door close button 102d to determine the number of passengers on board, in that it uses an information terminal 110 and an in-car beacon 165 to determine the number of passengers on board.

[0128] 13 is a schematic diagram showing a car 102 according to the eleventh embodiment. The control system 1 further includes an in-car beacon 165 installed in the car 102.

[0129] The control device 107 can grasp the information terminals 110 present in the car 102 using each of the information terminals 110 and the in-car beacon 165. The information terminals 110 can recognize the signal emitted by the in-car beacon 165 and recognize that their own position is inside the car 102.

[0130] When the information terminal 110 determines based on the in-car beacon 165 that the information terminal 110 itself has moved from the boarding floor into the car 102 and is now present inside the car 102, it can transmit a signal indicating this to the control device 107. The control device 107 counts the signals transmitted from the information terminals 110 and can determine how many information terminals 110 are now present inside the car 102 at that boarding floor.

[0131] This allows the control device 107 to grasp the number of information terminals 110 that are present in the car 102 at the boarding floor as the number of boarding passengers. The other configurations of the control system 1 of the eleventh embodiment are the same as the other configurations of the control system 1 of the first embodiment, and therefore description of the other configurations will be omitted.

[0132] The control system 1 for the elevator 101 according to the eleventh embodiment further includes an in-car beacon 165 installed in the car 102. Furthermore, the control device 107 can determine whether each information terminal 110 is present in the car 102 using each information terminal 110 and the in-car beacon 165. Furthermore, the control device 107 can determine the number of information terminals 110 that have become present in the car 102 at a specific boarding floor as the number of boarding passengers. This allows the car door 102b to be closed within a certain time period without relying on the passengers' judgment. Therefore, the convenience of the elevator can be further improved.

[0133] Embodiment 12 Embodiment 12 differs from embodiment 1, which uses the first door close button 102c and the second door close button 102d to determine the number of boarding passengers, in that it uses an information terminal 110 and a platform beacon 170 to determine the number of boarding passengers.

[0134] 14 is a schematic diagram showing a platform 202 according to the twelfth embodiment. The control system 1 further comprises one or more platform beacons 170 provided at each platform 202.

[0135] The control device 107 can use each of the information terminals 110 and the platform beacon 170 to determine whether or not an information terminal 110 is present at each platform 202. When the information terminal 110 recognizes a signal emitted by the platform beacon 170, it can transmit a signal to the control device 107 indicating that it is present at the corresponding platform 202.

[0136] On the other hand, when the information terminal 110 itself moves into the car 102 at the boarding floor, the information terminal 110 becomes unable to recognize the signal from the corresponding hall beacon 170, and the information terminal 110 stops transmitting the signal indicating that it is present at the corresponding hall 202 to the control device 107. In other words, each information terminal 110 can transmit a signal to the control device 107 indicating that it is present at the hall 202 only when it is present at that hall 202.

[0137] When the car door 102b is open at the boarding floor and the control device 107 determines that the presence of the information terminal 110 can no longer be confirmed at the boarding floor platform 202, it can determine that the number of boarding passengers has exceeded the number of call registrations containing boarding floor information that matches the boarding floor.

[0138] Based on this determination, the control device 107 can close the car door 102b before the lapse of a certain time. The other configurations of the control system 1 of the twelfth embodiment are the same as the other configurations of the control system 1 of the first embodiment, and therefore, description of the other configurations will be omitted.

[0139] The control system 1 for the elevator 101 according to the twelfth embodiment further includes one or more hall beacons 170 installed at each of the halls 202. Furthermore, the control device 107 can determine whether or not an information terminal 110 is present at the hall 202 at each boarding floor using each information terminal 110 and the hall beacon 170. Furthermore, when the control device 107 determines that no information terminal 110 is present at the hall 202 at a specific boarding floor, it determines that the number of boarding passengers is equal to or greater than the number of registered calls containing boarding floor information that matches the specific boarding floor, and can close the car door 102b. This allows the car door 102b to be closed within a certain period of time without relying on passengers' judgment. Therefore, the convenience of the elevator can be further improved.

[0140] Embodiment 13 The thirteenth embodiment differs from the first embodiment, which uses the first door close button 102c and the second door close button 102d to determine the number of boarding passengers, in that the thirteenth embodiment uses the position of the information terminal 110 itself to determine the number of boarding passengers.

[0141] Continuing the explanation, returning to Figure 1. As described above, the information terminal 110 can grasp its own position. That is, the information terminal 110 can grasp that it is moving from the hall 202 into the car 102.

[0142] When the information terminal 110 itself moves from the platform 202 into the car 102, the information terminal 110 can transmit to the control device 107 a boarding signal that indicates this.

[0143] The control device 107 can grasp the number of boarding passengers by counting the boarding signals transmitted by the information terminal 110. Other configurations of the control system 1 of the thirteenth embodiment are the same as other configurations of the control system 1 of the first embodiment, and therefore, description of the other configurations will be omitted.

[0144] According to the control system 1 for the elevator 101 of the thirteenth embodiment, each information terminal 110 can know that its own position has moved from the boarding floor to the car 102. Furthermore, each information terminal 110 can transmit a signal to the control device 107 indicating that it has moved from the boarding floor to the car 102. Furthermore, the control device 107 can know the number of passengers boarding by counting the signals. This allows the car door 102b to close within a certain time without relying on the passengers' judgment. Therefore, the convenience of the elevator can be further improved.

[0145] Embodiment 14 The fourteenth embodiment differs from the first embodiment in that the elevator 101 and the control system 1 are equipped with an authentication device 115 carried by each passenger and a destination floor registration device 116 installed at each landing 202, instead of an information terminal 110 as a call request generating device.

[0146] 15 is a schematic diagram showing a call request generation device according to embodiment 14. The elevator 101 and the control system 1 are equipped with, as the call request generation device, one or more authentication devices 115 carried by each passenger and a destination floor registration device 116 installed at each hall 202.

[0147] The authentication device 115 is, for example, an ID card that holds information unique to the corresponding passenger. The authentication device 115 holds information such as a usage authority that is an authority to use the elevator 101.

[0148] Each destination floor registration device 116 is connected to the control device 107 so that information can be communicated therewith. Each destination floor registration device 116 can generate a call request based on information from the authentication device 115 and transmit the generated call request to the control device 107. The control device 107 generates a call registration based on the call request.

[0149] Each destination floor registration device 116 has a registration device main body 116a, one or more destination floor buttons 116b installed on the registration device main body 116a, and a reading device 116c installed on the registration device main body 116a.

[0150] The one or more destination floor buttons 116b may be physical buttons or buttons displayed as images on a touch panel. The reader 116c can read information held by the authentication device 115 by contact or without contact.

[0151] Next, a description will be given of a passenger's use of the elevator 101 using the authentication device 115. When using the elevator 101, the passenger holds the authentication device 115 over the destination floor registration device 116, and then presses the destination floor button 116b corresponding to the desired destination floor.

[0152] The destination floor registration device 116 grasps, via the reading device 116c, the information held by the held authentication device 115. If the authority to use the elevator 101 held by the authentication device 115 is valid, the destination floor registration device 116 determines that the pressed destination floor button 116b is valid.

[0153] If the destination floor registration device 116 determines that the pressed destination floor button 116b is valid, it recognizes the floor corresponding to the pressed destination floor button 116b as the destination floor. That is, the destination floor registration device 116 can recognize the floor entered by the passenger based on the information of the corresponding authentication device 115 as the destination floor.

[0154] The destination floor registration device 116 is preset with the floor on which it is installed, and can grasp the floor on which it is installed as the boarding floor. As a result, the destination floor registration device 116 generates a call request with the floor on which it is installed as the boarding floor and the floor corresponding to the pressed destination floor button 116b as the destination floor.

[0155] The destination floor registration device 116 outputs the generated call request to the control device 107. The control device 107 can generate a call registration based on the input call request. The other configurations of the fourteenth embodiment are the same as the other configurations of the first embodiment, and therefore description thereof will be omitted.

[0156] Note that the destination floor registration device 116 in the fourteenth embodiment may be configured to register only specific floors as destination floors for any authentication device 115. For example, assume that the passengers are employees of a company located on the 10th to 13th floors of building 200.

[0157] In this case, the authentication device 115 carried by the passenger holds information that only floors 10 to 13 can be set as destination floors. Based on this information, the destination floor registration device 116 may be configured to set only floors 10 to 13 as the passenger's destination floors. In other words, if the passenger presses the destination floor button 116b indicating "floor 8" using the authentication device 115, the setting action may be ignored and "floor 8" may not be recognized as the destination floor.

[0158] Furthermore, based on information from the passenger authentication device 115, the destination floor registration device 116 may highlight the destination floor buttons 116b of only the destination floors that are valid for the authentication device 115. For example, the destination floor registration device 116 may light up only the destination floor buttons 116b that correspond to valid destination floors, or may display only the destination floor buttons 116b that correspond to valid destination floors on the touch panel.

[0159] The control system 1 for the elevator 101 according to the fourteenth embodiment further includes one or more authentication devices 115 carried by passengers and one or more destination floor registration devices 116 installed at each landing 202. Each destination floor registration device 116 recognizes the floor where the destination floor registration device 116 itself is installed as the boarding floor, and recognizes the floor input by the passenger as the destination floor based on the information of the corresponding authentication device 115, and can generate a call request corresponding to the authentication device 115, including information on the boarding floor and the destination floor. Each destination floor registration device 116 can output the generated call request to the control device 117. The control device 107 can generate a corresponding call registration based on the information of the authentication device 115. Therefore, by generating one call registration for each passenger carrying an authentication device 115, the control device 107 can accurately determine the number of passengers waiting for the car 102 at the boarding floor. Therefore, the number of boarding passengers can be accurately compared with the number of call registrations containing boarding floor information that matches a specific boarding floor, allowing for more accurate control.

[0160] In addition, in embodiments 1 to 14, if the number of boarding passengers is less than the number of call registrations containing boarding floor information that matches a specific boarding floor, and the car door 102b at the specific boarding floor has not remained open for a certain period of time, when the door close button is pressed, the control device 107 may make an announcement inside the car 102 using an announcement device (not shown), such as "Please wait a moment."

[0161] Furthermore, the control systems 1 of the first to fourteenth embodiments can be provided with the configurations and functions of the control systems 1 of the other embodiments as appropriate.

[0162] The functions of the first to fourteenth embodiments are realized by a processing circuit. Fig. 16 is a configuration diagram showing a first example of a processing circuit that realizes the functions of the control device 107 of the first to fourteenth embodiments.

[0163] Furthermore, the processing circuit 300 may be, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or a combination thereof.

[0164] 17 is a configuration diagram showing a second example of a processing circuit that realizes the functions of the control device 107 according to any one of the first to fourteenth embodiments. The processing circuit 310 of the second example includes a processor 311 and a memory 312.

[0165] In the processing circuit 310, the functions of the control device 107 are realized by software, firmware, or a combination of software and firmware. The software and firmware are written as programs and stored in the memory 312. The processor 311 realizes the functions by reading and executing the programs recorded in the memory 312.

[0166] It can also be said that the programs stored in memory 312 cause the computer to execute the procedures or methods of the above-mentioned sections. Here, memory 312 refers to non-volatile or volatile semiconductor memory, such as RAM (Random Access Memory), ROM (Read Only Memory), flash memory, EPROM (Erasable Programmable Read Only Memory), and EEPROM (Electrically Erasable and Programmable Read Only Memory). Magnetic disks, flexible disks, optical disks, compact disks, minidisks, DVDs, and the like also fall under memory 312.

[0167] It should be noted that the functions of the control device 107 described above may be partially realized by dedicated hardware and partially realized by software or firmware.

[0168] In this manner, the processing circuitry can implement the functions of the control device 107 described above by hardware, software, firmware, or a combination thereof.
