[0001] This invention relates to elevator systems. Background Technology

[0002] In the elevator utilization area detection device and elevator system disclosed in Patent Document 1 below, the utilization area detection device detects the location where pressure is applied by the feet or other objects of users inside the car. Furthermore, the utilization area detection device is installed on the car floor. The utilized location and area are determined based on the location where pressure is applied, and the car is determined to be full based on the area. The control device controls the elevator based on the determination result of the user area detection device. When the car is full, the control device does not respond to floor calls.

[0003] Existing technical documents

[0004] Patent Document 1: Japanese Patent Application Publication No. 2018-118846 Summary of the Invention

[0005] In the aforementioned prior art, when the elevator is deemed full based on pressure, location, and area using an area detection device, the control device does not respond to floor calls, thereby improving operational efficiency. However, this does not consider the situation where users inside the elevator car need to disembark at their destination floor when the car is full. For example, users located far from the elevator floor must squeeze through a group of other passengers to disembark. Therefore, there is a problem of not being able to disembark smoothly at the destination floor.

[0006] This invention was made to solve the aforementioned problems. The object of this invention is to provide an elevator system that allows users to smoothly give way to each other when descending the stairs.

[0007] The elevator system of the present invention comprises: a pressure detection unit arranged in a grid pattern on the car floor; a display unit arranged in a grid pattern on the car floor, capable of changing the display color; a car control panel having a destination floor control unit capable of displaying a predetermined color different for each destination floor; a footprint tracking unit that tracks footprints based on temporal changes detected by the pressure detection unit; and a display control unit that, when an operator operates the destination floor control unit after a footprint tracked by the footprint tracking unit approaches the car control panel, causes the destination floor control unit to display the destination floor control unit in a predetermined color corresponding to the destination floor, and also causes the display unit under the operator's feet to display in a predetermined color corresponding to the destination floor.

Detailed Implementation

[0041] The embodiments will now be described with reference to the accompanying drawings. In the drawings, identical or corresponding elements are labeled with the same reference numerals, and descriptions are simplified or omitted. Furthermore, the structures shown in the embodiments below illustrate one example of the technical concept of the present invention, which can be combined with other known technologies, or with multiple technical concepts described in the present invention. Moreover, some structures may be omitted or modified without departing from the spirit of the present invention.

[0042] Implementation method 1.

[0043] Figure 1 This is a perspective view of the elevator car in the elevator system of Implementation Method 1. Figure 2 This is a block diagram of the elevator system according to Implementation Method 1. (For example...) Figure 1 As shown, the car 1 is equipped with a door 2 and a car control panel 3. The car control panel 3 is located on the sleeve wall of the car 1. The car control panel 3 has multiple destination floor buttons 4. The destination floor buttons 4 can display a different color for each destination floor. For example, the destination floor buttons 4 can use multiple colors of light, or multiple colors of buttons can be preset to illuminate. The destination floor buttons 4 can also use LEDs as light sources, for example. The destination floor buttons 4 are an example of a destination floor operation unit. The destination floor operation unit is not limited to the destination floor buttons 4. The destination floor operation unit can be, for example, a touch panel, or a unit that can be operated in a non-contact manner.

[0044] Multiple pressure detection units 5 arranged in a grid pattern are provided on the car floor of the car 1. The pressure detection units 5 can detect the distribution of pressure acting on the car floor. For example, the pressure detection units 5 can also use resistive diaphragm pressure sensors. A resistive diaphragm pressure sensor has a structure in which a conductive pressure-sensitive ink layer and a lower electrode face each other with a spacer between them. When the pressure-sensitive ink layer is compressed, the contact area between the lower electrode and the conductive particles on the surface of the pressure-sensitive ink layer increases, thereby changing the resistance value. The pressure is determined by detecting this change in resistance value.

[0045] Multiple display units 6 arranged in a grid pattern are provided on the car floor. These multiple display units 6 are capable of changing the displayed color. Each of the multiple display units 6 arranged in a grid pattern can independently change the displayed color. For example, full-color LEDs can also be used for the display units 6.

[0046] like Figure 2 As shown, the car control panel 3 includes a control panel display 7, a control unit 8, an operation unit 9, and an input / output unit 10. A pressure detection unit 11 and a car floor display unit 12 are located on the car floor. The control unit 8, the pressure detection unit 11, and the car floor display unit 12 communicate with each other via the input / output unit 10.

[0047] In addition to displaying information such as the direction of movement of the car 1 and the floor number according to the instructions from the control unit 8, the operation panel display unit 7 also controls the display color of the destination floor button 4 according to the instructions from the control unit 8.

[0048] The operation unit 9 determines the operation of the car or the operation performed by the pressure of the car floor, and communicates with the control unit 8. The input / output unit 10 receives pressure information of the grid plane of the car floor as input, or outputs display information of the grid plane of the car floor, etc.

[0049] The pressure detection unit 11 continuously detects the time sequence of pressure distribution on the grid-like plane of the car floor detected by the pressure detection unit 5 and inputs it to the input / output unit 10. The car floor display unit 12 controls the display color of the display units 6 of each part of the car floor according to the instructions from the control unit 8.

[0050] The control unit 8 includes a footprint tracking unit that tracks a footprint based on temporal changes in the footprint detected by the pressure detection unit 5. The control unit 8 also includes a display control unit that, when the footprint tracked by the footprint tracking unit approaches the car control panel 3 and the operator presses the destination floor button 4, displays the destination floor button 4 in a predetermined color corresponding to the destination floor, and also displays the display unit 6 under the operator's feet in a predetermined color corresponding to the destination floor.

[0051] Therefore, a different color will be displayed under the feet of the operator who pressed the destination floor button 4, according to the destination floor. Thus, users in car 1 can know which floor other users are going to. Therefore, even when car 1 is full, users can smoothly give way to each other when getting off the stairs, thus ensuring a smooth descent.

[0052] The display control unit of the control unit 8 can also illuminate or flash the display unit 6 near the exit of the car 1 in a predetermined color corresponding to the destination floor before reaching the next destination floor. This allows other users to easily identify who is disembarking at the next floor.

[0053] The display control unit of control section 8 can also, when the pressure detection unit 5 detects that a person has boarded the elevator, cause the display unit under the passenger's feet to display a specific color other than the color specified on the car operation panel 3. For example, the display control unit can also cause the display unit 6 under the passenger's feet to display white when the pressure detection unit 5 detects that a person has boarded the elevator. White is an example of a specific color other than the color specified on the car operation panel 3, but it can also be any other color. In this way, by displaying a specific color under the passenger's feet, the presence of passengers in the car 1 can be visualized, thereby providing a sense of security that the elevator is aware of the presence of passengers. In addition, by visualizing the presence of passengers in the car 1, crime prevention can also be implemented.

[0054] The display control unit of the control unit 8 can also cause the display units 6 around the footprint to move as the footprint's foot moves. Thus, even when the user moves inside the car 1, the display under their feet can be shown in a color corresponding to the destination floor.

[0055] Figure 3 This is a flowchart illustrating an example of the processing performed by the control unit 8. Figure 4 This is an explanatory diagram showing the interior of car 1 as viewed from above. Figure 3 In step S1, when the car 1 begins to open, the control unit 8 determines whether pressure is detected within the area of ​​the car floor (step S2). This detects the person riding in car 1. If pressure is detected within the area of ​​the car floor, the control unit 8 determines whether it exceeds the area of ​​a predetermined minimum foot shape (step S3). Here, the control unit 8 detects the area of ​​a predetermined minimum foot shape, for example, a footprint larger than a child's size, based on the shape and area of ​​the detected pressure distribution. If a footprint is detected, the control unit 8 displays it in white on the display unit 6 under the foot (step S4). Next, the control unit 8 determines whether the car door has closed completely (step S5). When the door is closed completely, the process ends. If the door is not closed completely, the process returns to step S2.

[0056] exist Figure 4 In the example shown, passenger P1's footprint extends entirely into the car floor area and is therefore detected as a foot, illuminated in white. Passenger P2's footprint does not extend entirely into the car floor area and is therefore not detected as a foot, not illuminated in white. The shape and area of ​​the trolley's wheels differ from the minimum area specified for a foot shape and are therefore not detected as a foot, not illuminated in white.

[0057] Figure 5 This is a flowchart illustrating an example of the processing performed by the control unit 8. Figure 6 This is a diagram showing the car control panel 3. Figure 7 and Figure 8This is an explanatory diagram of the interior of car 1 as viewed from above. The operation is independent of door opening and closing or movement. Figure 5 The flowchart. As... Figure 5 In step S6, the control unit 8 determines whether someone has operated the car control panel 3. Here, as... Figure 6 As shown, passenger P1 presses the destination floor button 4. When the destination floor button 4 is pressed, the control unit 8 causes the destination floor button 4 to light up in the color unique to that destination floor (step S7).

[0058] Next, the control unit 8 determines the foot of the button 4 closest to the destination floor being operated within the operating range on the plane (step S8). Figure 7 In the example, passenger P1's single foot can be identified. Next, it is determined whether the display unit 6 showing the identified foot is white (step S9). If the identified foot is displayed as white, then... Figure 8 As shown, the display unit 6 under the determined foot is lit up with the color specific to the destination floor (step S10).

[0059] exist Figure 8 In the middle, passenger P2's target floor is the same as passenger P1's target floor, but he did not operate the destination floor button 4. Therefore, both feet display units 6 are displayed in white.

[0060] Figure 9 This diagram shows passenger P3 pressing the destination floor button 4 on the auxiliary control panel 13 located on the side wall of the car 1. Figure 10 This is an explanatory diagram showing the interior of car 1 as viewed from above. In this case, as... Figure 10 As shown, the control unit 8 determines the foot of passenger P3, which is closest to the sub-control panel 13 within the operating range on the plane, and illuminates the display unit 6 under that foot in the color unique to the destination floor.

[0061] Figure 11 This is a flowchart illustrating an example of the processing performed by the control unit 8. Figure 12 This is an explanatory diagram of the interior of car 1 as viewed from above. The operation is independent of door opening and closing or movement. Figure 11 The flowchart. In Figure 11 In step S11, the control unit 8 determines whether there is a color display indicating detected feet on the car floor. If there is a color display indicating detected feet on the car floor, it determines whether there is movement of detected feet on the car floor (step S12). Next, the control unit 8 causes the displayed color to move in sync with the movement of feet on the car floor (step S13).

[0062] exist Figure 12The example illustrates the movement of the feet of passengers P1, P2, and P3. For ease of understanding, only single-foot movement is shown in the accompanying diagram. Of course, movement is actually performed with both feet. Figure 12 As shown, the color under the foot indicates that it follows the movement as the foot moves.

[0063] When the pressure detection unit 5 detects a specific action, the display control unit of the control unit 8 changes the color of the display unit 6 under the foot of the foot that was detected performing the specific action. The specific action is, for example, stomping on the floor with one's foot. By performing a specific action, the user can change the color of their foot. For example, if the target floor is the same as other users' target floors, the color can be changed to the registered destination floor; or, if the user doesn't want others to know their target floor, the color can be changed to white.

[0064] Figure 13 This is a flowchart illustrating an example of the processing performed by the control unit 8. Figures 14 to 16 This is an explanatory diagram of the interior of car 1 as viewed from above. When in... Figure 13 In step S14, when the car 1 closes, it is determined whether more than one destination floor is registered in the car operation panel 3 (step S15). If more than one destination floor is registered, it is determined whether there is a detected foot color display on the car floor (step S16). If there is a detected foot color display, it is determined whether there is a specific action of stomping on the ground with a single foot displaying a color without changing its position on the ground (step S17). If a specific action is detected, the color of the display unit 6 under that foot is changed sequentially from the already displayed color to the color unique to the registered floor in the destination direction and then to white (step S18).

[0065] Next, when the person changing the color of the display unit 6 under their feet performs the same stomping motion with one foot (step S19), the color of the display unit 6 under their feet is determined to be the color currently displayed (step S20). Conversely, if no second stomping motion with the same foot is detected even after a predetermined time has elapsed (step S21), the color is restored to the previously displayed color (step S22). After step S20 or step S22, it is determined whether the opening of the car 1 has started (step S23). If the opening has started, the processing of this flowchart ends. If the opening has not yet started, the process returns to step S15.

[0066] exist Figure 14In the example, suppose that although passengers P1 and P3's feet are illuminated in the color corresponding to their destination floor, passenger P3 does not want the destination floor to be known, and therefore does not want the color to be displayed. Furthermore, suppose passenger P2's feet are both white, and he wants them to be displayed in the color corresponding to his destination floor.

[0067] like Figure 15 As shown, when passengers P2 and P3 perform a specific action of stomping their feet on the ground, the display color of the unit 6 under their feet changes sequentially to the color of the registered destination floor and then to white. Figure 16 As shown, passenger P2 performs a second specific action when the color of the display unit 6 under his feet changes to the color of his target floor, thereby enabling the display unit 6 under his feet to become the color of the destination floor. Passenger P3 performs a second specific action when the color of the display unit 6 under his feet changes to white, thereby enabling the display unit 6 under his feet to become white.

[0068] Figure 17 This is a flowchart illustrating an example of the processing performed by the control unit 8. Figures 18 to 20 This is an explanatory diagram of the interior of car 1 as viewed from above. When in... Figure 17 In step S24, when the car 1 closes, it is determined whether more than one destination floor is registered in the car operation panel 3 (step S25). If more than one destination floor is registered, it is determined whether there is a color display of detected feet on the car floor (step S26). Then, before reaching the destination floor (step S27), the display unit 6 near the exit of car 1 flashes in the color unique to the destination floor to be reached (step S28). As a result, other users can easily know who is getting off the stairs at the next destination floor, thus enabling smoother mutual yielding when getting off the stairs.

[0069] After step S28, it is determined whether the opening of car 1 has been completed (step S29). If the opening of car 1 has been completed, the flashing of the exit of car 1 in the color of the destination floor is stopped (step S30).

[0070] exist Figure 18 In the example, passengers P1 and P2 are on the same floor, and their floors are displayed in the same color. For example... Figure 19 As shown, before reaching the destination floor, the display unit at the exit of car 1 flashes the same color. Therefore, passenger P3 can easily know that passengers P1 and P2 are about to disembark. Figure 20 As shown, this allows for smoother mutual yielding when descending stairs.

[0071] Implementation method 2.

[0072] Next, refer to Figures 21 to 28 Embodiment 2 will be described, but the description will focus on the differences from Embodiment 1 described above, simplifying or omitting identical descriptions. Furthermore, elements that are the same as or correspond to those described above will be labeled with the same reference numerals.

[0073] In the above-described embodiment 1, the color display under the foot is only performed on one foot. The difference in this embodiment is that the color display is performed under both feet. Figure 3 , Figure 5 , Figure 17 The processing of the flowchart is also the same in this embodiment.

[0074] Figure 21 This is a flowchart illustrating an example of the processing performed by the control unit 8. Figures 22 to 24 This is an explanatory diagram of the interior of car 1 as viewed from above. The operation is independent of door opening and closing or movement. Figure 21 The flowchart. In Figure 21 In step S31, it is determined whether there is a color display of a detected foot on the car floor. If there is a color display of a detected foot, it is determined whether there is movement of the detected foot on the car floor (step S32). If there is movement of the detected foot, the displayed color moves along with the movement of the foot (step S33).

[0075] Next, it is determined whether the feet on the car floor are close together and whether they are standing within a specified distance from the foot with the color display (step S34). If the feet are close together and standing within a threshold distance set at the inside of the foot with the color display, the display unit 6 under the other foot also displays the color that has already been displayed (step S35).

[0076] Figure 22 The example shows passengers P1, P2, and P3 moving within car 1, but for ease of viewing, only one foot is shown. In reality, they move with both feet. Figure 23 As shown, when passengers P1, P2, and P3 bring their feet close to the station, the display unit 6 under the foot of the other foot, which is located within a set threshold distance inside the foot of the first foot, is lit up with the same color, based on the color of the foot that is displayed with the color of the destination floor.

[0077] In this embodiment, since the color display under the feet is shown on both feet, the user's destination floor can be more reliably communicated to other users.

[0078] Figure 25 This is a flowchart illustrating an example of the processing performed by the control unit 8. Figures 26 to 28This is an explanatory diagram of the interior of car 1 as viewed from above. When in... Figure 25 In step S36, when the car 1 closes, it is determined whether more than one destination floor is registered in the car operation panel 3 (step S37). If more than one destination floor is registered, it is determined whether there is a detected foot color display on the car floor (step S38). If there is a detected foot color display, it is determined whether there is a specific action of stomping the ground with one foot without changing the foot's position on the ground (step S39). If the specific action is detected, the color of the display unit 6 under the feet is changed sequentially from the already displayed color to the color unique to the registered floor in the destination direction and then to white (step S40). At this time, the colors of both feet are changed regardless of the foot that performed the specific action.

[0079] Next, when the person changing the color of the display unit 6 under their feet performs a stomping motion with the same single foot (step S41), the color of the display unit 6 under both feet is determined to be the color currently displayed (step S42). Conversely, if no second stomping motion with the same single foot is detected even after a predetermined time has elapsed (step S43), the color is restored to the previously displayed color (step S44). After step S42 or step S44, it is determined whether the opening of the car 1 has started (step S45). If the opening has started, the processing of this flowchart ends. If the opening has not yet started, the process returns to step S37.

[0080] exist Figure 26 In the example, suppose that although the display unit 6 under the feet of passengers P1 and P3 is lit up with the color corresponding to the destination floor, passenger P3 does not want others to know the destination floor, so he does not want the color of display unit 6 to be displayed. Furthermore, suppose that passenger P2's feet are both white, and he wants them to be displayed with the color corresponding to the destination floor.

[0081] like Figure 27 As shown, when passengers P2 and P3 perform a specific action of stomping their feet with one foot, the displayed color under their feet changes sequentially to the color of the already registered destination floor and then to white. Figure 28 As shown, passenger P2 performs a second specific action when the color under their feet changes to the color of their target floor, thereby enabling the display unit 6 under their feet to change to the color of the destination floor. Passenger P3 performs a second specific action when the color of the display unit 6 under their feet changes to white, thereby enabling the color under their feet to become white.

[0082] Figure 29This diagram illustrates an example of the structure that implements the functions of the control unit 8 of the present invention. The functions of the control unit 8 are implemented, for example, by a processing circuit. The processing circuit may also be dedicated hardware 600. The processing circuit may also include a processor 601 and a memory 602. A portion of the processing circuit is formed as dedicated hardware 600, and this processing circuit may also further include a processor 601 and a memory 602. Figure 9 In the example shown, a portion of the processing circuitry is configured as dedicated hardware 600. Furthermore, in Figure 29 In the example shown, the processing circuit, in addition to dedicated hardware 600, also includes a processor 601 and a memory 602.

[0083] A portion of the processing circuitry, which is at least one dedicated hardware 600, is a single circuit, a composite circuit, a programming processor, a parallel programming processor, an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or a combination thereof.

[0084] When the processing circuit has at least one processor 601 and at least one memory 602, the functions of each part of the control unit 8 are implemented by software, firmware, or a combination of software and firmware.

[0085] Software and firmware are described as programs and stored in memory 602. Processor 601 implements the functions of each part by reading and executing the programs stored in memory 602. Processor 601 is also referred to as CPU (Central Processing Unit), central processing unit, processing unit, arithmetic unit, microprocessor, microcomputer, or DSP. Memory 602 is, for example, 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 Programmable Read Only Memory), or disks, floppy disks, optical disks, CDs (compact disks), mini discs, and DVDs (Digital Versatile Disks).

[0086] Thus, the processing circuitry can implement the functions of the control unit 8 through hardware, software, firmware, or a combination thereof. Furthermore, the functions of the control unit 8 can be implemented through the collaboration of multiple devices or through a single device. Additionally, at least some of the functions of the control unit 8 can be installed on a server or similar device on an external network.

[0087] Alternatively, two or more features that can be combined from the above-described multiple embodiments can be combined for implementation.
