Description

Technical Field

[0001] This disclosure relates to elevator guidance devices. Background Technology

[0002] In existing elevator guidance devices, to inform passengers whether they are ready to enter the elevator, the sound emitted by the notification control unit changes according to the load weight inside the elevator car. Specifically, a set value X2 equivalent to the load weight when the car is full and a set value X1 less than the load weight when the car is full are set. When the load weight inside the car is less than the set value X1, the notification control unit maintains a certain music volume; when the load weight is above the set value X1 but less than the set value X2, the music volume gradually decreases; and when the load weight is above the set value X2, a buzzer sounds (see, for example, Patent Document 1).

[0003] Patent Document 1: Japanese Patent Application Publication No. 8-188351

[0004] In existing elevator guidance systems, an audible alert is used to indicate whether the elevator is ready for boarding. A buzzer sounds when the set value exceeds twice the maximum capacity. The buzzer also sounds when the elevator car is full (i.e., the total load exceeds the car's maximum capacity). This causes the passenger to be noticed by other passengers who boarded before them, potentially causing psychological distress. Summary of the Invention

[0005] This disclosure was made to solve the aforementioned problem, and its purpose is to provide an elevator guiding device, an elevator guiding method, and an elevator guiding procedure that, when the total load inside the car exceeds the car's maximum load capacity due to a passenger entering the car, prevents the passenger from attracting the attention of other passengers who have traveled in the car before that passenger.

[0006] The elevator guiding device disclosed herein includes: a load measuring unit that measures the total load inside the car; a detection unit that detects the position of the last passenger who entered the car; a display unit that displays a first display indicating that the total load measured by the load measuring unit is greater than a first set value which is the maximum load capacity of the car; and a display control unit that controls the display unit to display the first display in the vicinity of the position of the last passenger detected by the detection unit when the total load measured by the load measuring unit is greater than the first set value.

[0007] Invention Effects

[0008] According to the elevator passenger guidance device disclosed herein, when the total load inside the car is greater than the maximum load capacity of the car due to a passenger entering the car, the passenger is prevented from attracting the attention of other passengers who have entered the car before the passenger.

Detailed Implementation

[0025] Implementation Method 1

[0026] The structure of the elevator car floor 1 and its surrounding area in Embodiment 1 will be described. Figure 1 This is a diagram showing the elevator car floor 1 and its surroundings in Embodiment 1. Figure 1 (a) is a cross-sectional view of the car as seen from above on the car floor 1. Figure 1 (b) is a front view of the car floor 1 as seen from the car entrance / exit 2 side. Additionally, in Figure 1 In (b), the illustration of the car wall 3 is omitted.

[0027] exist Figure 1 In (a), the car floor 1 is installed in the car, and the upper surface of the car floor 1 is approximately rectangular. One side of the upper surface of the car floor 1 forms part of the car entrance / exit 2, while the three sides that do not form the car entrance / exit 2 are connected to the car wall 3. Furthermore, the car floor 1... Figure 1 The surface on the upper side of (b) of the paper is called the upper surface 1a. Figure 1 The surface below the paper of (b) is called the lower surface 1b. The upper surface 1a is the load-bearing surface in the car floor 1 for passengers to step on.

[0028] The upper surface 1a of the car floor 1 has grid-like regions 1c. Each subdivided region within the grid region 1c is called a block region 1d. For example... Figure 1 As shown in (a), the grid area 1c is positioned on the side of the car entrance / exit 2, closer to the center of the car floor 1 than the center of the car floor 1 in the depth direction. The grid area 1c, for example, occupies one-third of the upper surface 1a of the car floor 1. The grid area 1c is designed with the initial contact point of the feet of the final passenger 12, described later, when they enter the car. Furthermore, as... Figure 1As shown in (b), a plurality of detection units 4 and a plurality of display units 5 are arranged on the lower surface 1b of the car floor 1. Each detection unit 4 and each display unit 5 is respectively arranged on the lower surface 1b of each region 1d of the car floor 1. Alternatively, each detection unit 4 and each display unit 5 can be arranged on the lower surface 1b side of each region 1d; for example, there may be space between each region 1d and each detection unit 4 and each display unit 5. Furthermore, in Figure 1 In (a) and (b), for illustrative purposes, block region 1d of grid region 1c is illustrated using dashed lines. Additionally, the depth direction of the car floor 1 is... Figure 1 The up and down directions in the paper of (a).

[0029] The detection unit 4 detects the position of the last passenger 12 who entered the car. The detection unit 4 is, for example, a pressure detection device. The pressure detection device detects the pressure applied to the upper surface 1a of the car floor 1. When the last passenger 12 steps on the grid area 1c of the car floor 1, the detection unit 4, located on the lower surface 1b of the block area 1d where the last passenger 12 is stepping, detects the pressure, and thus detects the position of the last passenger 12. That is, the detection unit 4 detects that the position of the last passenger 12 is located at least a portion of the upper surface 1a of the block area 1d where pressure is applied. Here, in Figure 1 In the lower left corner of paper (a), the position of the final passenger 12's feet is simply illustrated by using a dotted line to enclose the area, with the final passenger 12's right foot in contact with grid area 1c. Therefore, as Figure 1 As shown in (a), the final passenger 12's position is, for example, the position where the final passenger 12's foot contacts the upper surface 1a of the car floor 1. When pressure is detected, the detection unit 4 sends a signal indicating that pressure has been detected to the display control unit 8a, which will be described later.

[0030] Furthermore, when the final passenger 12 walks and moves within the grid area 1c of the upper surface 1a of the car floor 1, the detection unit 4 can also detect the position of the final passenger 12. Specifically, the detection unit 4 analyzes the pattern of the moment when the pressure disappears when the final passenger 12 lifts their foot from the upper surface 1a and the moment when pressure is generated when they put their foot down on the upper surface 1a, thereby determining whether the position where pressure is generated is the position of the final passenger 12. For example, if pressure is detected at two positions after the positions of the final passenger 12's two feet are detected, and the pressure at one of the detected pressure positions disappears while new pressure is generated at a position about one step away from that position, it can be determined that the position where new pressure is generated is the position of the final passenger 12's single foot.

[0031] Furthermore, when multiple passengers are riding in the elevator car and in grid area 1c, the detection unit 4 can also detect the position of each passenger. Based on the time of pressure loss and gain, the detection unit 4 analyzes parameters such as the passenger's direction of movement, distance traveled, and stationary position to detect the position of each passenger, thereby determining which location each passenger has moved to after boarding the elevator. In other words, the detection unit 4 can determine the current position of each passenger, and therefore can identify each passenger. Moreover, it can determine who will ultimately pass through the elevator car entrance / exit 2, thus identifying passengers who have already boarded the elevator (11) and the final passenger (12). This analysis structure can be implemented by the detection unit 4 itself, or it can be implemented by other devices that send data to the detection unit 4.

[0032] In addition, Figure 1 In the lower left of the paper in (a), region 13, spanning four block regions 1d, is shown as the location of the final passenger 12 and the area near the location of the final passenger 12. Here, the location of the final passenger 12 and the area near the location of the final passenger 12 are continuous, and the area near the location of the final passenger 12 represents the portion of the upper surface 1a of a block region 1d that is in contact with the feet of the final passenger 12, where the feet of the final passenger 12 are not in contact.

[0033] Display unit 5 displays a first display that can be visually confirmed by the final passenger 12. Display unit 5 is, for example, a lighting device that illuminates or flashes light. For example, as the first display, display unit 5 flashes a red light. Furthermore, when display unit 5 is a lighting device, the car floor 1 is formed of a transparent or translucent component that transmits light, so that the final passenger 12 can visually confirm the light emitted by display unit 5 from the upper surface 1a of the car floor 1. Alternatively, only the grid area 1c in the car floor 1 may be formed of a transparent or translucent component that transmits light.

[0034] A load detection sensor 6 is installed in the car to detect the load inside the car. For example, Figure 1 As shown in (a), load detection sensors 6 are disposed at the four corners of the lower surface 1b of the car floor 1 to detect the loads applied to the four corners respectively. The load detection sensors 6 are, for example, differential transformers. A differential transformer is a displacement sensor that measures the amount of displacement associated with the elastic deformation of a spring (not shown) in the differential transformer and converts it into a voltage corresponding to the total load in the car.

[0035] Next, the structure of the elevator guide device 100a in Embodiment 1 will be described. Figure 2This is a structural diagram of the elevator guide device 100a according to Embodiment 1. The elevator guide device 100a includes a detection unit 4, a display unit 5, a load detection sensor 6, a door opening / closing detection unit 20, a door opening / closing control unit 21, a load calculation unit 7, and a display control unit 8a. Furthermore, the functions of the door opening / closing detection unit 20, the load calculation unit 7, and the display control unit 8a are implemented via the elevator control panel 10a.

[0036] The door opening / closing detection unit 20 is installed in the car or car frame, etc., to detect the opening / closing status of the car doors. When the door opening / closing detection unit 20 detects that the car door is open, it sends an open signal indicating that the car door is open to the door opening / closing control unit 21. When the door opening / closing detection unit 20 detects that the car door is closed, it sends a closed signal indicating that the car door is closed to the door opening / closing control unit 21.

[0037] The door opening and closing control unit 21 receives signals from the elevator operation control unit (not shown) instructing the car doors to open or close, and controls the opening and closing of the car doors based on these signals. Furthermore, the door opening and closing control unit 21 determines the opening or closing status of the car doors based on the opening or closing signals sent by the door opening and closing detection unit 20.

[0038] The load calculation unit 7 is connected to the load detection sensor 6 in a communicable manner, and calculates the total load inside the car based on the detection results of the load detection sensor 6. For example, if the load detection sensor 6 is a differential transformer, when the load calculation unit 7 receives a voltage converted by the differential transformer, it converts it into a load equivalent to that voltage and calculates the total load inside the car. The load calculation unit 7 outputs the information of the total load inside the car to the display control unit 8a.

[0039] Alternatively, the load detection sensor 6 and the load calculation unit 7 can be installed together, or they can be configured to detect the load inside the car and calculate the total load inside the car using a single device. Hereinafter, the structure that has the functions of the load detection sensor 6 and the load calculation unit 7 and measures the total load inside the car will be referred to as the load measuring unit 30.

[0040] The display control unit 8a is connected to the detection unit 4, the display unit 5, and the load calculation unit 7 in a communicative manner. The display control unit 8a determines whether the total load inside the car measured by the load measuring unit 30 is greater than the first set value T1. Here, the first set value T1 sets the maximum load capacity of the car. In addition, the maximum load capacity of the car refers to the maximum load that the car can move when it is loaded with passengers or other goods.

[0041] If the total load inside the car is greater than the first set value T1, the display control unit 8a determines whether the detection unit 4 has detected the position of the final passenger 12. If the detection unit 4 has detected the position of the final passenger 12, the display control unit 8a controls the display unit 5 to display the first display in the area 13 containing the position of the final passenger 12 detected by the detection unit 4 and its surrounding area.

[0042] That is, when the total load measured by the load measuring unit 30 is greater than the first set value T1, the display control unit 8a controls the display unit 5 so that the display unit 5 displays the first display in the area 13 containing the location of the final passenger 12 detected by the detection unit 4 and the surrounding area.

[0043] Here, the first display can be described as indicating that the total load inside the car is greater than a first set value T1, which is the maximum load capacity of the car. Therefore, in order to draw the attention of the final passenger 12, the first display is preferably a visually striking display. For example, if the display unit 5 is a lighting device, then as the first display, the display unit 5 can flash a red light.

[0044] Furthermore, if the detection unit 4 does not detect the position of the final passenger 12, the display control unit 8a will not control the display unit 5. Additionally, if the total load inside the car is below the first set value T1, the display control unit 8a will not control the display unit 5.

[0045] Here, the hardware structure of the elevator control panel 10a in Embodiment 1 will be described. Figure 3 This diagram illustrates the hardware structure of the elevator control panel 10a in Embodiment 1. The elevator control panel 10a is implemented, for example, by a computer such as a personal computer or a microcontroller.

[0046] The elevator control panel 10a has a processor 41, a memory 42, an interface 43, and a secondary storage device 44 that are connected to each other via a bus 40.

[0047] The processor 41 is, for example, a CPU (Central Processing Unit). The processor 41 reads the operation program stored in the secondary storage device 44 into the memory 42 and executes it, thereby realizing the various functions of the elevator control panel 10a.

[0048] Memory 42 is, for example, a main storage device composed of RAM (Random Access Memory). Memory 42 stores programs read by processor 41 from secondary storage device 44. In addition, memory 42 functions as working memory when processor 41 executes programs.

[0049] Interface 43 is, for example, an I / O (Input / Output) interface such as a serial port, a USB (Universal Serial Bus) port, or a network interface. Input is received from the detection unit 4 and the load detection sensor 6 through interface 43, and output is sent to the display unit 5.

[0050] Secondary storage device 44 is, for example, flash memory, HDD (Hard Disk Drive), or SSD (Solid State Drive). Secondary storage device 44 stores various information required for the operation of elevator guide device 100a and programs executed by processor 41.

[0051] Next, the operation of the elevator guide device 100a in Embodiment 1 will be described. Figure 4 This is a flowchart illustrating the operation of the elevator guide device 100a in Embodiment 1. Figure 4 (a) is the overall flowchart. Figure 4 Figure (b) shows the details of S10. Furthermore, it is explained that the detection unit 4 uses a pressure detection device, the display unit 5 uses a lighting device, and the load detection sensor 6 uses a differential transformer. In the lighting device, the first display uses a flashing red light. Additionally, it is assumed that the position of the final passenger 12 and the surrounding area of ​​the final passenger 12 are a continuous area 13 spanning four block areas 1d.

[0052] In step S1, the door opening / closing control unit 21 determines whether the car door is open based on the door opening / closing detection unit 20. When the door opening / closing control unit 21 receives the door opening signal from the door opening / closing detection unit 20, it determines that the car door is open and proceeds to step S2. When the door opening / closing control unit 21 does not receive the door opening signal from the door opening / closing detection unit 20, it determines that the car door is not open and repeats step S1.

[0053] In step S2, the load measuring unit 30 measures the total load inside the car. Specifically, the load calculation unit 7 receives the voltage converted by the differential transformer, which serves as the load detection sensor 6, converts it into a load equivalent to that voltage, calculates the total load inside the car, and thus measures the total load inside the car. The load calculation unit 7 then sends the total load inside the car to the display control unit 8a.

[0054] In step S3, the display control unit 8a determines whether the total load inside the car measured by the load measuring unit 30 is greater than the first set value T1. If the display control unit 8a determines that the total load inside the car is greater than the first set value T1, the process proceeds to step S10. If the display control unit 8a determines that the total load inside the car is not greater than the first set value T1, that is, the total load inside the car is less than or equal to the first set value T1, the process proceeds to step S4.

[0055] Here, the display control (S10) of the first display will be explained. Step S10 is the process by which the display control unit 8a controls the display unit 5 to display using the first display, and it consists of four steps: S11 to S14. In step S11, the display control unit 8a determines whether the detection unit 4 has detected the position of the final passenger 12. If the display control unit 8a receives a signal from the detection unit 4 indicating that pressure has been detected, it determines that the detection unit 4 has detected the position of the final passenger 12, and the process proceeds to step S12. If the display control unit 8a does not receive a signal from the detection unit 4 indicating that pressure has been detected, it determines that the detection unit 4 has not detected the position of the final passenger 12, and the process proceeds to step S2.

[0056] In step S12, the display control unit 8a controls the display unit 5 to display the first display in area 13, which includes the location of the final passenger 12 detected by the detection unit 4 and its vicinity. By controlling it in this way, the display unit 5 displays the first display. Light emitted from the display unit 5 shines through area 13, thus displaying the first display on the upper surface 1a of the block area 1d of the car floor 1, allowing the final passenger 12 to visually confirm the first display.

[0057] Regarding step S12, a specific example will be given for explanation. Figure 5 This is a diagram showing the passenger's position on the elevator car floor 1 in Embodiment 1. Figure 5 To illustrate the passenger's position on the elevator, the position of the passenger's feet is simplified in the diagram. One final passenger 12 and five passengers 11 who boarded the elevator before the final passenger 12 are seated in the elevator car. Furthermore, the feet of each of the passengers 11 who boarded the elevator and the final passenger 12 are shown surrounded by dashed lines. Here, the right foot of the final passenger 12 is in contact with at least a portion of each of the four block areas 1d. These four block areas 1d correspond to the aforementioned area 13.

[0058] exist Figure 5In the following state: when the final passenger 12 places their right foot on area 13, the total load inside the car is greater than the first set value T1, and the detection unit 4 detects the position of the final passenger 12. In this case, the display control unit 8a controls the display unit 5 to display a first display on the display unit 5 corresponding to area 13, which contains the position of the final passenger 12 and the area near it detected by the detection unit 4. Specifically, the display unit 5 displays a flashing red light as the first display. Area 13 transmits light emitted by the display unit 5, so the first display is displayed on the upper surface 1a of the block area 1d of the car floor 1, and the final passenger 12 can visually confirm the flashing red light. In addition, when the final passenger 12 walks on the grid area 1c of the upper surface 1a of the car floor 1, the detection unit 4 can also detect the position of the final passenger 12. Thus, even if the final passenger 12 moves, the display unit 8a controls the display unit 5 to display the first display on the block area 1d that is in contact with at least a portion of the final passenger 12's feet.

[0059] Furthermore, the detection unit 4 can also detect the positions of passengers other than the final passenger 12, i.e., passengers 11 who have already boarded the elevator, in the grid area 1c. Therefore, it can identify the final passenger 12 and other passengers. Consequently, in the grid area 1c, except for the block area 1d that at least partly contacts the feet of the final passenger 12, the first display is not controlled by the display control unit 8a to be displayed on the display unit 5. Specifically, in Figure 5 In the grid area 1c, there are two passengers 11 who have already taken the elevator. However, the block area 1d that is in contact with the feet of these two passengers 11 is not controlled by the display control unit 8a to display the first display on the display unit 5.

[0060] return Figure 4 The operation of the elevator guide device 100a will be further explained. In step S13, the display control unit 8a determines whether the total load inside the car measured by the load measuring unit 30 is greater than the first set value T1. If the display control unit 8a determines that the total load inside the car is greater than the first set value T1, step S12 is repeated. If the display control unit 8a determines that the total load inside the car is not greater than the first set value T1, that is, the total load inside the car is less than or equal to the first set value T1, the process proceeds to step S14.

[0061] In step S14, the display control unit 8a stops the display unit 5 from displaying the first display. Then, the process proceeds to step S2.

[0062] Next, in step S4, the door opening / closing control unit 21 determines whether the car door is in a closed state based on the closing signal sent by the door opening / closing detection unit 20. If the door opening / closing control unit 21 receives a closing signal from the door opening / closing detection unit 20, it determines that the car door is in a closed state and ends the process. If the door opening / closing control unit 21 does not receive a closing signal from the door opening / closing detection unit 20, it determines that the car door is not in a closed state and proceeds to step S2.

[0063] As described above, in the elevator guide device 100a of Embodiment 1, when the total load measured by the load measuring unit 30 is greater than a first set value, the display control unit 8a controls the display unit 5 to display the first display in region 13, which includes the area near the position of the final passenger 12 detected by the detection unit 4. Thus, when the first display is displayed in region 13 near the position of the final passenger 12, the final passenger 12 can easily visually confirm the first display and easily recognize that the total load in the car is greater than the maximum load capacity of the car. Furthermore, since the display unit 5 displays the first display in the position of the final passenger 12 and the adjacent area, it is not easy for passengers who have already ridden the elevator 11 to visually confirm the first display. Therefore, when the total load in the car is greater than the maximum load capacity of the car due to the final passenger 12 entering the car, it is possible to suppress the attention of passengers who have already ridden the elevator 11 to the final passenger 12.

[0064] Furthermore, the display unit 5 displays the first display in the area of ​​the car floor 1 closer to the car entrance / exit 2 than the center of the car floor 1 in the depth direction. As a result, it is not easy for passengers 11 who have already taken the elevator to visually confirm the first display when they are located on the opposite side in the depth direction of the car floor 1, and it is easy for the final passenger 12 who has entered the car from the car entrance / exit 2 to visually confirm the first display.

[0065] Furthermore, the grid area 1c only needs to be the area in the car floor 1 that includes the position where the feet of the final passenger 12 initially contact the car floor 1 when they enter the car, and the extent of this area can be appropriately set. In addition, the car floor 1 can also have areas divided into other shapes instead of the grid area 1c.

[0066] Furthermore, the detection unit 4 can be any device that detects the position of the final passenger 12, and is not limited to a pressure detection device. For example, it can also be configured to detect the position of the final passenger 12 by means of a camera installed in the car or at a landing.

[0067] Furthermore, the display unit 5 can be any device that displays a first display that the final passenger 12 can visually confirm, and is not limited to a lighting device. For example, a projector installed on the ceiling of the car, the car wall 3, or a landing and capable of projecting onto the car floor 1 can also be used. In addition, as the first display, it can also be indicated by characters or illustrations that the total load in the car is greater than the first set value T1.

[0068] Furthermore, the display unit 5 can also be positioned lower than the center of the car wall 3 in the height direction, instead of on the upper surface 1a of the car floor 1. For example, the lower part of the car wall 3 could be a portion of the car wall 3 located less than 1 meter from the upper surface 1a of the car floor 1. This way, when the first display is displayed at a position lower than the line of sight of the passengers 11 who have already ridden the elevator, it is not easy for the passengers 11 to visually confirm the first display, while the final passenger 12 entering the car from the car entrance 2 can easily visually confirm the first display.

[0069] Furthermore, the range of the area near the location of the final passenger 12 detected by the detection unit 4 can be appropriately set. For example, it can also be as follows: Figure 6 The area shown is the surrounding area. Figure 6 This is a variation of the elevator guide device in Embodiment 1, and is a diagram showing the passenger's boarding position at the elevator car floor 1. Figure 6 In the middle, passenger 11 who had already taken the elevator and passenger 12 who were the final passengers were... Figure 5 The same number of passengers and the same conditions exist, but area 13, which includes the location of the final passenger 12 and its vicinity, comprises 16 block areas 1d, unlike the description above. Thus, when area 13 includes block areas 1d that do not contact the feet of the final passenger 12, the first display is displayed over a wider area compared to when area 13 only includes block areas 1d that contact at least a portion of the feet of the final passenger 12. Therefore, even when the total load inside the car exceeds the car's maximum load capacity due to the final passenger 12 entering the car, it is possible to prevent the final passenger 12 from attracting the attention of the passengers 11 who have already ridden the elevator, and the final passenger 12 can easily visually confirm the first display.

[0070] Alternatively, the area near the final passenger 12's position can be, for example, the area within 10 cm from the point where the final passenger 12's foot contacts the upper surface 1a of the car floor 1. Furthermore, the area near the final passenger 12's position may not be continuous with the final passenger 12's position.

[0071] Furthermore, the following example is illustrated: the display control unit 8a controls the display unit 5 to display the first display in region 13, which includes the location of the final passenger 12 detected by the detection unit 4 and its vicinity. However, the display control unit 8a may also control the display unit 5 to display the first display only in the vicinity of the location of the final passenger 12 detected by the detection unit 4. That is, the display unit 5 may not display the first display at the location of the final passenger 12, but only in the vicinity of the location of the final passenger 12. For example, the display unit 5 may not display the first display in the block area 1d that is in contact with the feet of the final passenger 12, but in the block area 1d that is not in contact with the feet of the final passenger 12. In this case, the block area 1d that is not in contact with the feet of the final passenger 12 becomes the vicinity of the location of the final passenger 12.

[0072] Furthermore, the functions of the door opening / closing detection unit 20, the door opening / closing control unit 21, the load calculation unit 7, and the display control unit 8a are implemented through the elevator control panel 10a, but are not limited thereto. For example, these functions can also be implemented by connecting a separate computer to the elevator control panel 10a or by using an elevator control server.

[0073] Implementation Method 2

[0074] The structure of the elevator guide device 100b in Embodiment 2 will be described. Figure 7 This is a structural diagram showing the structure of the elevator guide device 100b in Embodiment 2. Furthermore, structures identical to those in Embodiment 1 are labeled with the same reference numerals, and their descriptions are omitted.

[0075] The elevator guide device 100b in Embodiment 2 differs from the elevator guide device 100a in Embodiment 1 in that the operation of the display control unit 8b is realized through the control panel 10b.

[0076] Based on the operation of the display control unit 8a, if the total load inside the car measured by the load measuring unit 30 is less than or equal to the first set value T1, the display control unit 8b determines whether the total load inside the car is greater than the second set value T2. Here, the second set value T2 is set to a value smaller than the first set value T1, preferably a value that is about a few passengers smaller than the maximum load capacity. That is, it is preferable that the second set value T2 is less than or equal to the first set value T1 and is obtained by subtracting the weight of a predetermined number of passengers from the maximum load capacity of the car. Hereinafter, we will explain the second set value T2 as a value obtained by subtracting the weight of one passenger from the maximum load capacity of the car. In addition, the weight of each passenger can also be a value specified by law or standard. When setting the value of the second set value T2, the number of passengers' weights to be subtracted can also be appropriately determined according to the size of the car and the actual usage of the elevator.

[0077] If the total load inside the car is less than or equal to a first set value T1 but greater than a second set value T2, the display control unit 8b determines whether the detection unit 4 has detected the position of the final passenger 12. If the detection unit 4 has detected the position of the final passenger 12, the display control unit 8b controls the display unit 5 to display a second display in the area 13 containing the position of the final passenger 12 detected by the detection unit 4 and its vicinity.

[0078] That is, when the total load measured by the load measuring unit 30 is less than or equal to the first set value T1 and greater than the second set value T2, the display control unit 8b controls the display unit 5 so that the display unit 5 displays the second display in the area 13 containing the location of the final passenger 12 detected by the detection unit 4 and its surrounding area.

[0079] Here, the second display can be described as indicating that the remaining load before reaching the first set value is less than the weight of the specified number of passengers. In other words, it can be described as indicating that the car is approaching its maximum load capacity. Therefore, compared to displaying the first display, displaying the second display has a lower priority in alerting the final passenger 12, but it is preferable to display it visually clearly. For example, if the display unit 5 is an illumination device and the first display flashes red light, the second display can also illuminate yellow light. Furthermore, the remaining load is a value obtained by subtracting the total load measured by the load measuring unit 30 from the first set value, representing the load that can be borne from the current total load up to the maximum load capacity.

[0080] Furthermore, if the detection unit 4 does not detect the position of the final passenger 12, the display control unit 8b will not control the display unit 5. Additionally, if the total load inside the car is below the second set value T2, the display control unit 8b will not control the display unit 5.

[0081] Next, the operation of the elevator guide device 100b in Embodiment 2 will be explained. Figure 8 This is a flowchart illustrating the operation of the elevator guide device 100b in Embodiment 2. Figure 8 (a) is the overall flowchart. Figure 8 Figure (b) shows the details of S20. Furthermore, the description of the steps identical to those of the elevator guide device 100a in Embodiment 1 is omitted. Additionally, the second display is illuminated in yellow. Furthermore, the location of the final passenger 12 and the surrounding area of ​​the final passenger 12 are assumed to be a region 13 that continuously spans six block regions 1d.

[0082] In step S3, the display control unit 8b determines whether the total load inside the car measured by the load measuring unit 30 is greater than the first set value T1. If the display control unit 8b determines that the total load inside the car measured by the load measuring unit 30 is greater than the first set value T1, the process proceeds to step S10. If it determines that the total load inside the car measured by the load measuring unit 30 is not greater than the first set value T1, i.e., the total load inside the car is less than or equal to the first set value T1, the process proceeds to step S21. In step S10, the display control unit 8b performs display control for the first display. In step S21, the display control unit 8b determines whether the total load inside the car measured by the load measuring unit 30 is greater than the second set value T2. If the display control unit 8b determines that the total load inside the car is greater than the second set value T2, the process proceeds to step S20. If the display control unit 8b determines that the total load inside the car is not greater than the second set value T2, i.e., the total load inside the car is below the second set value T2, the process proceeds to step S4.

[0083] Here, the display control (S20) of the second display will be explained. Step S20 is the process by which the display control unit 8b controls the display unit 5 to display using the second display, and consists of four steps: S22 to S25. In step S22, the display control unit 8b determines whether the detection unit 4 has detected the position of the final passenger 12. If the display control unit 8b receives a signal from the detection unit 4 indicating that pressure has been detected, it determines that the detection unit 4 has detected the position of the final passenger 12, and the process proceeds to step S23. If the display control unit 8b does not receive a signal from the detection unit 4 indicating that pressure has been detected, it determines that the detection unit 4 has not detected the position of the final passenger 12, and the process proceeds to step S2.

[0084] In step S23, the display control unit 8b controls the display unit 5 to display the second display in area 13, which includes the location of the final passenger 12 detected by the detection unit 4 and its vicinity. By controlling it in this way, the display unit 5 displays the second display. Light emitted from the display unit 5 shines through area 13, thus displaying the second display on the upper surface 1a of the block area 1d of the car floor 1, allowing the final passenger 12 to visually confirm the second display.

[0085] Regarding step S23, a specific example will be given for explanation. Figure 9 This diagram illustrates the passenger positions at the elevator car floor 1 in Embodiment 2. One final passenger 12 and four passengers 11 who boarded the elevator before the final passenger 12 are seated in the car. Here, the left foot of the final passenger 12 is in contact with at least a portion of each of the six block areas 1d. These six block areas 1d correspond to area 13.

[0086] exist Figure 9 In the following state: when the final passenger 12 places their right foot on area 13, the total load inside the car is below the first set value T1 and above the second set value T2, and the detection unit 4 detects the position of the final passenger 12. In this case, the display control unit 8b controls the display unit 5 to display a second display on the display unit 5 corresponding to area 13, which contains the position of the final passenger 12 and the area near it detected by the detection unit 4. Specifically, the display unit 5 displays the illumination of yellow light as the second display. Area 13 transmits the light emitted by the display unit 5, so the second display is displayed on the upper surface 1a of the block area 1d of the car floor 1, and the final passenger 12 can visually confirm the illumination of the yellow light. In addition, similar to Embodiment 1, each passenger is identified by the detection unit 4, so thereafter, the display control unit 8b controls the display unit 5 to display the second display on the block area 1d in the grid area 1c, which at least a portion of it is in contact with the foot of the final passenger 12. Furthermore, regarding the block area 1d in grid area 1c, which at least a portion of which is in contact with the feet of the passenger 11 who has already boarded the elevator, the second display is not controlled by the display control unit 8b to be displayed on the display unit 5.

[0087] return Figure 8 The operation of the elevator guide device 100b will be further explained. In step S24, the display control unit 8b determines whether the total load inside the car measured by the load measuring unit 30 is greater than the second set value T2. If the display control unit 8b determines that the total load inside the car is greater than the second set value T2, the process proceeds to step S23. If the display control unit 8b determines that the total load inside the car is not greater than the second set value T2, i.e., the total load inside the car is less than or equal to the second set value T2, the process proceeds to step S25.

[0088] In step S25, the display control unit 8b stops the display unit 5 from displaying the second display. Then, the process proceeds to step S2. The subsequent processing is the same as the operation of the elevator guide device 100a in Embodiment 1.

[0089] Here, a specific example is given to illustrate the following situation: In step S20, the display control unit 8b uses the second display to control the display unit 5. After the process enters step S2, in step S10, the display control unit 8b uses the first display to control the display unit 5. Figure 10 It is shown Figure 9 The following is a diagram showing the passenger seating positions at point 1 on the elevator car floor. Figure 11 It is shown Figure 10 The following is a diagram showing the passenger seating positions at point 1 on the elevator car floor.

[0090] exist Figure 10 There are 5 passengers, 11 in total, already riding the elevator in the car. One of these 11 passengers is... Figure 9 The final passenger 12, from Figure 9 The state of moving inside the car, in Figure 10 In the middle, located at the lower right of the paper. That is, Figure 10 Passenger 14a, located in the lower right corner of the paper, is... Figure 9 The final passenger is the same person as passenger 12. Passenger 14a stepped on the car... Figure 9 At that point in time, the total load inside the car is below the first set value T1 and greater than the second set value T2. Therefore, in Figure 10 Even if passenger 14a moves, area 13a, including the location of passenger 14a and its surrounding area, is also displayed using the second display. Furthermore, in Figure 10 In the middle, the passengers newly boarding the car are represented in the lower left corner of the paper. Figure 10 Passenger 14b of the final passenger 12.

[0091] exist Figure 11 Passenger 14a did not leave Figure 10 The passenger 14b moves, placing his right foot on one of the four block areas 1d of the upper surface 1a of the car floor 1. Here, assuming that the total load inside the car is greater than a first set value T1 at the moment the passenger 14b steps on the car floor, area 13b, including the position of the passenger 14b and its vicinity, is displayed using the first display. Here, in... Figure 11 In, also with Figure 10 Similarly, area 13a, which includes the location of passenger 14a and its surrounding area, is displayed using the second display. Thus, when step S10 is performed after step S20, sometimes both the first and second displays are displayed.

[0092] As described above, in the elevator guide device 100b of Embodiment 2, the display unit 5 displays a second display indicating that the remaining load before reaching the first set value T1 is less than the weight of a predetermined number of passengers. When the total load measured by the load measuring unit 30 is less than the first set value T1 and greater than the second set value T2 (obtained by subtracting the weight of a predetermined number of passengers from the maximum load capacity of the car), the display control unit 8b controls the display unit 5 to display the second display in the vicinity of the position of the final passenger 12 detected by the detection unit 4. By controlling it in this way, the final passenger 12 can decide whether to wait and wait for the next ride or rush to try riding. Furthermore, when neither the first nor the second display is displayed, the final passenger 12 can determine that there is sufficient weight margin and can ride without feeling uneasy about being overweight.

[0093] In addition, during the operation of the elevator guide device 100b, sometimes the first display and the second display are displayed simultaneously. However, it can also be configured such that when the first display and the second display are displayed simultaneously, the display of the second display is eliminated and only the first display is displayed.

[0094] Implementation Method 3

[0095] The structure of the elevator guide device 100c in Embodiment 3 will be described. Figure 12 This is a structural diagram showing the structure of the elevator guide device 100c in Embodiment 3. Furthermore, structures identical to those in Embodiment 2 are labeled with the same reference numerals, and their descriptions are omitted.

[0096] The elevator guide device 100c in Embodiment 3 differs from the elevator guide device 100b in Embodiment 2 in that the operation of the display control unit 8c is realized through the control panel 10c.

[0097] Based on the operation of the display control unit 8b, if the total load inside the car measured by the load measuring unit 30 is less than or equal to the first set value T1, the display control unit 8c determines whether the total load inside the car is greater than the second set value T2. If the total load inside the car is not greater than the second set value T2, i.e., the total load inside the car is less than or equal to the second set value T2, the display control unit 8c determines whether the detection unit 4 has detected the position of the final passenger 12. If the detection unit 4 has detected the position of the final passenger 12, the display control unit 8c controls the display unit 5 to display the third display in the area 13 containing the position of the final passenger 12 detected by the detection unit 4 and its surrounding area.

[0098] That is, when the total load measured by the load measuring unit 30 is less than or equal to the second set value T2, the display control unit 8c controls the display unit 5 to display the third display in the area 13 containing the location of the final passenger 12 detected by the detection unit 4 and its vicinity. Conversely, when the detection unit 4 does not detect the location of the final passenger 12, the display control unit 8c does not control the display unit 5.

[0099] Here, the third display can be described as indicating that the remaining load before reaching the first set value T1 is greater than or equal to the weight of the specified number of passengers. In other words, the third display can be described as indicating that there is a margin up to the maximum load capacity of the car. Therefore, compared to displaying the first or second display, displaying the third display has a lower priority in alerting the final passenger 12; however, a visually striking display is preferable. For example, if the display unit 5 is an illumination device and the first display flashes red light, the third display can also illuminate green light.

[0100] Next, the operation of the elevator guide device 100c in Embodiment 3 will be explained. Figure 13 This is a flowchart illustrating the operation of the elevator guide device 100c in Embodiment 3. Figure 13 (a) is the overall flowchart. Figure 13 Figure (b) shows the details of S30. Furthermore, the description of the steps identical to those of the elevator guide device 100b in Embodiment 2 is omitted. Additionally, the third display is illuminated in green. Furthermore, the location of the final passenger 12 and the surrounding area are assumed to be a continuous region 13 spanning seven block regions 1d.

[0101] If, in step S21, the display control unit 8c determines that the total load inside the car measured by the load measuring unit 30 is below the second set value T2, the process proceeds to step S30.

[0102] Here, the display control (S30) of the third display will be explained. Step S30 is the process by which the display control unit 8c controls the display unit 5 to display using the third display, and it consists of two steps, S31 and S32. In step S31, the display control unit 8c determines whether the detection unit 4 has detected the position of the final passenger 12. If the display control unit 8c receives a signal from the detection unit 4 indicating that pressure has been detected, it determines that the detection unit 4 has detected the position of the final passenger 12, and the process proceeds to step S32. If the display control unit 8c does not receive a signal from the detection unit 4 indicating that pressure has been detected, it determines that the detection unit 4 has not detected the position of the final passenger 12, and the process proceeds to step S4.

[0103] In step S32, the display control unit 8c controls the display unit 5 to display the third display in area 13, which includes the location of the final passenger 12 detected by the detection unit 4 and its vicinity. By controlling it in this way, the display unit 5 displays the third display. Light emitted from the display unit 5 shines through area 13, thus displaying the first display on the upper surface 1a of the block area 1d of the car floor 1, allowing the final passenger 12 to visually confirm the third display. After step S32, the process proceeds to step S4.

[0104] Regarding step S32, a specific example will be given for explanation. Figure 14 This diagram shows the passenger positions at the elevator car floor 1 in Embodiment 3. One final passenger 12 and three passengers 11 who boarded the elevator before the final passenger 12 are riding in the car. Here, the left foot of the final passenger 12 is in contact with at least a portion of each of the seven block areas 1d. These seven block areas 1d correspond to area 13.

[0105] exist Figure 14 In the following state: when the final passenger 12 places their right foot on area 13, the total load inside the car is below the second set value T2, and the detection unit 4 detects the position of the final passenger 12. In this case, the display control unit 8c controls the display unit 5 to display a third display on the display unit 5 corresponding to area 13, which contains the position of the final passenger 12 and the area around it detected by the detection unit 4. Specifically, the display unit 5 displays the illumination of green light as the third display. Area 13 transmits light emitted by the display unit 5, so the second display is displayed on the upper surface 1a of the block area 1d of the car floor 1, and the final passenger 12 can visually confirm the illumination of the green light. In addition, similar to Embodiment 2, each passenger is identified by the detection unit 4, so thereafter, the display control unit 8c controls the display unit 5 to display the third display on the block area 1d in the grid area 1c, at least a portion of which is in contact with the foot of the final passenger 12. Furthermore, regarding the block area 1d in the grid area 1c, which at least a portion of which is in contact with the feet of the passenger 11 who has already boarded the elevator, the display control unit 8c does not control the display unit 5 to display the third display.

[0106] return Figure 13 In step S4, the door opening / closing control unit 21 determines whether the car door is in a closed state based on the closing signal sent by the door opening / closing detection unit 20. When the door opening / closing control unit 21 receives a closing signal from the door opening / closing detection unit 20, it determines that the car door is in a closed state and proceeds to step S33. When the door opening / closing control unit 21 does not receive a closing signal from the door opening / closing detection unit 20, it determines that the car door is not in a closed state and proceeds to step S2.

[0107] In step S33, the display control unit 8c causes the display unit 5 to stop displaying the third display. Then, the process ends.

[0108] As described above, in the elevator guide device 100c of Embodiment 3, the third display indicates that the remaining load before reaching the first set value T1 is greater than or equal to the weight of the specified number of passengers. When the total load is less than or equal to the second set value T2, the display control unit 8c controls the display unit 5 to display the third display in the vicinity of the position of the final passenger 12 detected by the detection unit 4. In this way, when the third display is displayed in the area 13 containing the vicinity of the position of the final passenger 12, the final passenger 12 can easily visually confirm the third display, and the final passenger 12 can easily recognize that there is a margin between the total load in the car and the maximum load capacity of the car, so that the final passenger 12 can quickly board the car without feeling uneasy about being overloaded.

[0109] Alternatively, if it is determined in step S4 that the car door is closed, the process proceeds to step S33, and the display control unit 8c stops the display unit 5 from displaying the third display. However, it is also possible that the display control unit 8c stops the display unit 5 from displaying the third display just before the car door closes.

[0110] The structure shown in the above embodiments illustrates one example of the content of this disclosure. The embodiments can be combined with other known technologies. Parts of the structure of the embodiments can be omitted or modified without departing from the spirit of this disclosure.
