Description

[Technical Field]

[0001] The present invention relates to an elevator information output system. [Background technology]

[0002] Elevators have traditionally been installed in many buildings and are an important part of the infrastructure. In the event of a large-scale disaster, there is a concern that many people will become trapped inside elevators due to power outages. Regarding elevator entrapment, a technology has been disclosed for a "novel elevator car entrapment detection device that can accurately detect only humans, simultaneously measure the health status of passengers, and detect passengers even when they are stationary" (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2003-040540 Summary of the Invention [Problem to be solved by the invention]

[0004] The elevator car entrapment detection device described in Patent Document 1 is based on the premise that there is a power supply. However, during a power outage, it is conceivable that devices that use power will become unusable, and other means such as emergency buttons will also become unusable. Furthermore, even if the situation inside the elevator is captured by a surveillance camera, there is no way to view it during a power outage, making it impossible to confirm whether someone is trapped inside. In the event of a large-scale disaster, it is necessary to determine which elevator should be opened first.

[0005] Therefore, an object of the present invention is to provide an elevator information output system that can check whether or not someone is trapped in an elevator even during a power outage caused by a large-scale disaster or the like. [Means for solving the problem]

[0009] Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, this is merely an example, and the technical scope of the present invention is not limited to this example. (First embodiment) <Elevator 3 Overview> FIG. 1 is a diagram showing an example of a building in which an elevator 3 according to the first embodiment is installed. FIG. 2 is a diagram showing an example of the interior and exterior of the passenger car 31 of the elevator 3 according to the first embodiment.

[0010] 1 shows an example of a building B in which a general elevator 3 is installed. The elevator information output system 100 is applicable to the building B in which the elevator 3 is installed, as an example. Building B has door D1 (door) for getting on and off elevator 3 on the floor where entrance / exit E is located, and each floor has doors D2, ..., Dn according to the floor number. In the following explanation, when the floor number is not specified, it will be simply referred to as "door D". The elevator 3 includes an elevator control device (not shown) in the hoistway, a passenger car 31, a rope 3a, a counterweight 3b, and a hoisting machine 3c. The rope 3a is a member that connects the passenger car 31 and the counterweight 3b. The counterweight 3b is a member for balancing the weight with the passenger car 31. The hoist 3c is a device for raising, lowering, and stopping the passenger car 31 by being rotationally driven based on a control signal from an elevator control device.

[0011] In this figure, the elevator 3 is described as being of the rope type, but it is not limited to this and may be of other mechanisms such as hydraulic type. Also, the elevator 3 may be of the rope type or of other types. The elevator 3 also has various other devices such as buffers and guide rails, but these are not essential to the present invention and therefore will not be described here. FIG. 2(A) is a diagram showing the inside of the passenger car 31. The passenger car 31 has a space for passengers P to board. Additionally, a camera 32 (photographing device) is installed in the elevator car 31. The camera 32 is installed in a position where it can photograph the entire elevator car 31, and photographs passengers P and the door D. The camera 32 is constantly photographing, and transmits the photographed images to the information output device 1 (described later).

[0012] FIG. 2(B) shows the door D1 for getting on and off the elevator 3 as seen from the landing on the floor where the entrance E is located. The right side of door D1 is provided with a direction indicator 5a, a floor indicator 5b, and a call button 5c. The direction indicator 5a indicates the direction of movement of the passenger car 31, and in this example, indicates that the passenger car 31 is descending. The floor indicator 5b indicates the position of the passenger car 31, and in this example, indicates that it is moving to the third floor or from the third floor to the second floor. The call button 5c is a button that passengers at the landing can press to call the elevator 3 when they want to board. In this example, since the landing is on the first floor, only the upward call button 5c is provided. In addition, a board 6 is provided below the call button 5c. The board 6 is a plate-shaped member on which the electronic paper 4 is placed. The electronic paper 4 displays the number of passengers P in the car 31.

[0013] <Principles of Electronic Paper 4> Here, the principle of the electronic paper 4 will be briefly explained. FIG. 3 is a diagram illustrating the structure of the electronic paper 4 according to the first embodiment. Electronic paper 4 is a display device that displays pictures and text as a collection of dots called "pixels." Electronic paper 4 displays pictures and text by sandwiching an electronic ink layer with pixels arranged between transparent electrodes and controlling the display by applying voltage to each pixel. The electronic paper 4 may be of a type such as a twist ball type or an electrophoretic type, but here, the electronic liquid powder type will be described as an example.

[0014] FIG. 3 shows one pixel of electronic paper 4. Electronic paper 4 is arranged between a front panel 41 and a rear panel 42, with transparent electrodes 43 in contact with each panel. A space 44 sandwiched between the two transparent electrodes 43 is filled with air. Electronic powder particles 45 and 46 are sealed in space 44. Electronic powder particles 45 are white and positively charged. Electronic powder particles 46 are black and negatively charged. Applying a voltage to transparent electrode 43 causes particles of electronic powder 45 and electronic powder 46 to move, and powder of the selected color is collected on the front panel 41 side, which is the display surface, to perform display.

[0015] In the example shown in Figure 3, the transparent electrode 43 on the front panel 41 side is at a negative voltage, and the transparent electrode 43 on the back panel 42 side is at a positive voltage, so the positively charged electronic powder 45 moves to the front panel 41 side, and a white color is displayed. The electronic paper 4 displays characters and the like based on the above-mentioned principle. Therefore, information once displayed is characterized in that it will not disappear even if the power is cut off due to a power outage or the like, or can be maintained with extremely small amounts of power. Furthermore, if the electronic paper 4 is equipped with, for example, a dry cell battery as a backup power source, it will be possible to continue displaying the output characters.

[0016] <Overall Configuration of Elevator Information Output System 100> Next, the elevator information output system 100 will be described. FIG. 4 is a functional block diagram of the elevator information output system 100 according to the first embodiment. The elevator information output system 100 is a system for outputting the number of passengers P boarding the elevator car 31 (see Figure 2(A)) of the elevator 3 on an electronic paper 4 (see Figure 2(B)) installed at the elevator 3 landing, for example, near the door D1 of a floor having an entrance / exit E of a building B.

[0017] The elevator information output system 100 includes an information output device 1, a camera 32 installed in a passenger car 31 of an elevator 3, and an electronic paper 4 provided on a board 6. The information output device 1 and the camera 32, and the information output device 1 and the electronic paper 4 are connected so as to be able to communicate with each other. The communication connection method may be, for example, a communication network such as the Internet, and may be either wired or wireless.

[0018] <Information output device 1> The information output device 1 analyzes the image from the camera 32 to determine the number of passengers P, and outputs the information to an electronic paper 4 provided outside the elevator 3. The information output device 1 is, for example, a personal computer (PC), but may also be a server or the like. As shown in FIG. 2, the information output device 1 includes a control unit 10, a storage unit 20, and a communication interface unit 29. The control unit 10 is a central processing unit (CPU) that controls the entire information output device 1. The control unit 10 appropriately reads and executes an operating system (OS) and various application programs stored in the storage unit 20, thereby cooperating with the above-mentioned hardware and executing various functions.

[0019] The control unit 10 includes an image acquisition unit 11, an image analysis unit 12, a number of people confirmation unit 13, and an information output unit 16. The image acquisition unit 11 acquires from the camera 32 an image captured by the camera 32. The image analysis unit 12 functions as a number of people acquisition means. The image analysis unit 12 analyzes the image acquired by the image acquisition unit 11. The image analysis unit 12 then checks whether the door D is closed or not. The image analysis unit 12 also checks the location of the passenger P. The number of passengers confirmation unit 13 has a function as a number of passengers acquisition means. The number of passengers confirmation unit 13 acquires the number of passengers P in the elevator 3 based on the locations of the passengers P confirmed by the image analysis unit 12. The information output unit 16 functions as an information output unit and outputs the number of people acquired by the number of people confirmation unit 13 to the electronic paper 4. The details of each of these functions will be described later.

[0020] The storage unit 20 is a storage device such as a hard disk or semiconductor memory element for storing programs, data, etc. required for the operation of the information output device 1. The storage unit 20 includes a program storage unit 21 . The program storage unit 21 is a storage area that stores various programs. The program storage unit 21 stores various programs including, for example, an information output program 21a. The information output program 21a is a program for performing the various functions executed by the control unit 10 described above.

[0021] The communication interface unit 29 is an interface for performing communication between the camera 32 and the electronic paper 4. It should be noted that a computer refers to an information processing device equipped with a control unit, a storage device, etc., and the information output device 1 is an information processing device equipped with a control unit 10, a storage unit 20, etc., and is included in the concept of a computer.

[0022] <Processing Description> Next, the processing of the information output device 1 will be described. FIG. 5 is a flowchart showing the information output process of the information output device 1 according to the first embodiment. This information output process is performed while power is being supplied to the information output device 1. In step S (hereinafter, "step S" will be simply referred to as "S") 11 of FIG. 5, the image acquisition unit 11 of the information output device 1 acquires an image from the camera 32.

[0023] In S12, the image analysis unit 12 analyzes the acquired image. Image analysis can be performed using various image recognition techniques, including known person recognition techniques. In S13, the image analysis unit 12 determines whether the door D is closed or not using the image analysis result. If the door D is closed (S13: YES), the control unit 10 shifts the process to S14. On the other hand, if the door D is not closed (S13: NO), the control unit 10 shifts the process to S19.

[0024] In S14, the number of passengers confirmation unit 13 confirms the number of passengers P inside the elevator car 31 from the analysis result of the image. In S15, the information output unit 16 outputs the confirmed number of passengers P to the electronic paper 4. This process enables the electronic paper 4 to display the number of passengers P. Thereafter, the control unit 10 moves the process to S11.

[0025] On the other hand, in S19, the information output unit 16 outputs "Getting on and off" to the electronic paper 4. This process allows the text "Getting on and off" to be displayed on the electronic paper 4. Thereafter, the control unit 10 moves the process to S11. In the above description, the text "Getting in and out" is output to the electronic paper 4 when the door D is not closed, but the present invention is not limited to this. In the case of a simple electronic paper 4, a symbol other than a number, such as a "- (hyphen)", may be output.

[0026] As described above, according to the first embodiment, the elevator information output system 100 has the following advantages. (1) The information output device 1 acquires the number of passengers P in the elevator car 31 of the elevator 3, and outputs the acquired number of passengers to an electronic paper 4 provided outside the elevator 3, which retains the display information even when the power is cut off. Therefore, the number of passengers P in the elevator 3 can be confirmed from outside the elevator 3. In addition, since the number of passengers P is output to the electronic paper 4, the display on the electronic paper 4 is maintained even during a power outage due to a large-scale disaster or the like, so the number of passengers P just before the elevator 3 can be ascertained from outside, and people outside can confirm whether or not any passengers are trapped in the elevator 3.

[0027] (2) The information output device 1 acquires the number of people when the door D of the elevator 3 is closed. Therefore, when door D is closed, that is, when people are trapped, it is possible to know whether they are trapped or not by acquiring and displaying the number of people.

[0028] (3) The information output device 1 analyzes the image captured by the camera 32 capturing the image of the inside of the elevator car 31 to obtain the number of passengers. Therefore, by analyzing the image, it is possible to grasp the number of passengers P inside the elevator car 31 and confirm the number of passengers.

[0029] (4) The electronic paper 4 is installed near the landing on the floor having the entrance E of the building B equipped with the elevator 3. Therefore, in the event of a power outage due to a large-scale disaster or the like, for example, a person rushing through entrance E of building B can immediately check whether or not anyone is trapped in the elevator car 31 of the elevator 3.

[0030] (5) The information output device 1 is configured to output, to the electronic paper 4, information indicating that the door D of the elevator 3 is open while the door D is open. Therefore, while the door D is open, no one will be trapped inside, and this fact can be recognized from the outside.

[0031] (Second embodiment) In the second embodiment, a case where there are multiple elevators in the same building, an elevator control device that controls the elevators receives operation-related signals and increases the information output content will be described. In the following description, parts that perform the same functions as in the first embodiment described above will be given the same reference numerals or the same reference numerals with the same suffixes, and duplicate descriptions will be omitted as appropriate.

[0032] <Overall Configuration of Elevator Information Output System 200> FIG. 6 is a functional block diagram of an elevator information output system 200 according to the second embodiment. FIG. 7 is a diagram showing an example of a board 206 on which electronic paper sheets 204a to 204e according to the second embodiment are arranged. The elevator information output system 200 grasps the number of passengers P getting on two elevators 203A and 203B installed in the same building using cameras 32A and 32B installed in the elevators 203A and 203B, respectively. In addition, information related to the elevators 203A and 203B is output to electronic paper 204b to 204e on a board 206 installed in a control room in the building, for example.

[0033] In the following explanation, when individual elevators 203A and 203B are not specified, they will be simply referred to as elevator 203, omitting the suffix A or B. Furthermore, each device provided in each elevator 203A or 203B will be similarly described with the suffix A or B, but when it is not necessary to specify them, the suffix A or B will be similarly omitted. The elevator information output system 200 comprises an information output device 201, a camera 32 installed in the passenger car 31 of each elevator 203, an elevator control device 233 (elevator control means) that controls each elevator 203, and electronic paper 204a to 204e (see Figure 7 described later) on a board 206.

[0034] <Information output device 201> The information output device 201 analyzes the images from each camera 32 to determine the number of passengers P in each elevator 203, and outputs the information, including the date and time and the direction of ascent and descent of the elevator 3, to electronic paper 204a to 204e on the board 206. The information output device 201 shown in FIG. 6 includes a control unit 210, a storage unit 220, and a communication interface unit 29.

[0035] The control unit 210 includes an image acquisition unit 211 , an image analysis unit 212 , a number of people confirmation unit 213 , a date and time acquisition unit 214 , a control signal receiving unit 215 , and an information output unit 216 . The image acquisition unit 211 acquires the images captured by the cameras 32 from the cameras 32 . The image analysis unit 212 functions as a number of people acquisition means. The image analysis unit 212 analyzes each image acquired by the image acquisition unit 211. Then, the image analysis unit 212 confirms the location of passengers P in each elevator 203. The number of passengers confirmation unit 213 has a function as a number of passengers acquisition means. The number of passengers confirmation unit 213 acquires the number of passengers P in each elevator 203 based on the location of the passengers P in each image confirmed by the image analysis unit 212.

[0036] The date and time acquisition unit 214 has a function as a date and time acquisition means. The date and time acquisition unit 214 acquires date and time information of the current date and time. For example, the information output device 201 may have a clock function and the date and time information may be acquired from there, or may be acquired from an external source such as a radio-controlled clock. The control signal receiving unit 215 functions as a position obtaining means. The control signal receiving unit 215 receives signals related to operation from the elevator control device 233 of each elevator 203. The control signal receiving unit 215 receives, as the signal related to operation, for example, a signal related to the ascending / descending direction of the passenger car 31.

[0037] The information output unit 216 functions as an information output means. The information output unit 216 outputs date and time information acquired by the date and time acquisition unit 214 to the electronic paper 204a. The information output unit 216 also outputs the number of people in each elevator 203 acquired by the number of people confirmation unit 213 to the electronic papers 204b and 204c. Furthermore, the information output unit 216 outputs symbols corresponding to the signals relating to the ascending and descending direction received by the control signal receiving unit 215 to the electronic papers 204d and 204e. The storage unit 220 includes a program storage unit 221 . The program storage unit 221 stores various programs including an information output program 221a, which is a program for performing the various functions executed by the control unit 210 described above.

[0038] <Board 206> The board 206 is a plate-like member installed in the building where each elevator 203 is located, for example, in a control room. FIG. 7 shows an example of the board 206. The electronic paper 204a displays the date and time. The electronic paper 204b displays the number of passengers P in the elevator 203A. The electronic paper 204c displays the number of passengers P in the elevator 203B. The electronic paper 204d displays the ascending and descending direction of the elevator 203A. The electronic paper 204e displays the ascending and descending direction of the elevator 203B.

[0039] 7 illustrates an example in which each piece of information is output to a different electronic paper 204, but each piece of information may be output to one electronic paper 204. In this case, it is desirable to output information about which elevator 203 the information belongs to in association with identification information that identifies the elevator 203.

[0040] <Processing Description> Next, the processing of the information output device 201 will be described. FIG. 8 is a flowchart showing the information output process of the information output device 201 according to the second embodiment. In S211 of FIG. 8, the image acquisition unit 211 of the information output device 201 acquires an image from the camera 32 of each elevator 203. In S212, the image analysis unit 212 analyzes the acquired image. Then, the number of passengers confirmation unit 213 confirms the number of passengers P inside the elevator car 31. In S213, the information output unit 216 outputs the confirmed number of passengers in each elevator 203 to the electronic paper 204 corresponding to the number of passengers display in each elevator 203. In S214, the date and time acquisition unit 214 acquires the current date and time. In S215, the information output unit 216 outputs the acquired date and time to the electronic paper 204a.

[0041] In S216, the control signal receiving unit 215 receives a signal relating to the ascending / descending direction from the elevator control device 233 of each elevator 203 as a signal relating to operation. In S217, the information output unit 216 outputs the ascending and descending directions to the electronic paper 204 corresponding to the number of people displayed in each elevator 203. In S218, the control unit 210 determines whether a predetermined time has arrived. The control unit 210 performs the information output process at predetermined time intervals. The predetermined time is the timing for updating the display, and is therefore preferably a short interval such as 10 seconds. If the predetermined time has arrived (S218: YES), the control unit 210 proceeds to S211. On the other hand, if the predetermined time has not arrived (S218: NO), the control unit 210 remains in this process until the predetermined time arrives.

[0042] The process of S211, the process of S214, and the process of S216 may be performed simultaneously, or may be performed in a different order than described above. Furthermore, the process of S213, the process of S215, and the process of S217 may be performed together if the process of the previous stage has been completed.

[0043] As described above, according to the second embodiment, the elevator information output system 200 has the following advantages. (1) The information output device 201 acquires the number of people in each elevator 203 at predetermined time intervals. Therefore, by periodically outputting the number of passengers in each elevator 203 to the electronic paper 4, the number of passengers in each elevator 203 can be known from outside.

[0044] (2) The information output device 201 obtains the ascending and descending direction of the passenger car 31 from each elevator control device 233 that controls the ascent and descent of each elevator 203, and further outputs the ascending and descending direction of the passenger car 31 to the electronic paper 204d and 204e. Therefore, information about the elevator 203, including the direction of movement of the elevator 203, can be acquired, and by outputting this information to the electronic paper 4, the direction of movement of the elevator 203 can be grasped from the outside.

[0045] (3) The information output device 201 acquires the date and time when the number of people was acquired and further outputs the date and time on the electronic paper 204a. Therefore, along with the number of passengers, the date and time when the information was acquired can be confirmed.

[0046] Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments. Furthermore, the effects described in the embodiments are merely a list of the most preferable effects resulting from the present invention, and the effects of the present invention are not limited to those described in the embodiments. Note that the above-described embodiments and the modified embodiments described below can be used in appropriate combinations, but detailed description thereof will be omitted.

[0047] (Variations) (1) In the second embodiment, a signal related to the elevator's movement is received from the elevator control device and output to electronic paper. However, this is not limiting. For example, the position acquisition means of the information output device may receive a position signal related to the floor number of the elevator car from the elevator control device and output the signal to electronic paper. In this way, if a person is trapped inside the elevator, it becomes possible to grasp the approximate location of the elevator car from outside.

[0048] (2) In the second embodiment, an example has been described in which a signal related to elevator control is received from an elevator control device and information is output, but this is not limited to this. For example, an acceleration sensor (sensor device) may be provided in the elevator car, and the information output device may receive a signal from the acceleration sensor, allowing the elevation direction acquisition means of the information output device to acquire the elevation direction of the elevator. In this way, the information output device can acquire the elevation direction of the elevator without being connected to the elevator control device for communication, and information acquisition can be achieved using a simple device and method.

[0049] (3) In each embodiment, the camera installed in the car is positioned so as to capture an image of the entire car, but the present invention is not limited to this. For example, the camera may be installed above the entrance of the car and be capable of counting the number of passengers getting on and off the car. Alternatively, since it is sufficient to be able to confirm the passengers in the elevator car, the elevator car may be provided with a sensor that can detect a human body, such as an infrared sensor, rather than a camera.

[0050] (4) In each embodiment, an example has been described in which an electronic paper display is provided in a building having an elevator to display the number of passengers in the elevator car, thereby responding to situations such as being trapped during a power outage. However, this is not limiting. For example, the electronic paper display may be provided in an elevator management company, for example, connected to the information output device 1 so as to be able to communicate with the information output device 1. In this way, even if the power is cut off during a power outage, it is possible to remotely determine whether passengers were trapped in the elevator just before the power outage when the power was being supplied. This allows for the order of response measures, such as the order in which to rescue trapped passengers, to be determined. [Explanation of symbols]
