Based on this, elevator maintenance workers may stand on top of the elevator and visually inspect the wire ropes for maintenance. In such a case, in the technique of Patent Document 1, a data recorder is required to process the signals output by the encoder, which is cumbersome for on-site maintenance work.

Mode for Carrying Out the Invention

[0017] 〔Embodiment 1〕 Hereinafter, an embodiment of the present disclosure will be described in detail.

[0018] <Configuration of Elevator System 900> First, the configuration of the elevator system (elevator) 900 according to the present embodiment will be described.

[0019] FIG. 1 is a schematic diagram showing the configuration of the elevator system 900 according to the present embodiment and an example of the situation in which the information processing system 100 described later according to the present embodiment is used. As shown in FIG. 1, the elevator system 900 includes a car 910, a rope 920, a counterweight 930, a hoist 940, a control panel 950, and a hoistway PA.

[0020] The car 910 is a device that accommodates and transports users of the elevator system 900. The car 910 moves up or down in the hoistway PA described later. As shown in FIG. 1, the car 910 has a pulley at the bottom. Also, as shown in FIG. 1, the car 910 includes a control device 911 and a speaker (sound output unit) 912. The control device 911 and the speaker 912 will be described later. The upper surface of the car 910 may have holes for transmitting the sound output from the speaker 912 to the outside of the car 910.

[0021] The rope 920 is a linear member that suspends and raises / lowers the car 910. The ends of the rope 920 are connected to the ceiling of the hoistway PA, which will be described later. Between the ends of the rope 920, the pulleys provided on the car 910, the hoist 940, and the pulleys provided on the counterweight 930, which will be described later, are wound in this order. The rope 920 is, as an example, a wire formed by twisting a plurality of steel wires together.

[0022] The counterweight 930 is a member that offsets the weight of the car 910. As shown in FIG. 1, the counterweight 930 has a pulley at the upper part.

[0023] The hoist 940 is a device that rotates and sends out the rope 920 in one direction to raise or lower the car 910. The rotation of the hoist 940 is controlled by the control panel 950, which will be described later.

[0024] The control panel 950 is a device that controls the operation of the elevator system 900. The control panel 950 may receive input information from the control device 911, which will be described later, and control the operation of the elevator system 900 based on the received input information. As an example, the control panel 950 is arranged near the hoist 940.

[0025] As an example of controlling the operation of the elevator system 900, the control panel 950 operates the hoist 940 to raise or lower the car 910. Specifically, the control panel 950 rotates the hoist 940 in a certain rotation direction (hereinafter referred to as the "forward rotation direction"), sends out the rope 920 by a certain delivery length toward the counterweight 930 side, and raises the car 910. Also, the control panel 950 rotates the hoist 940 in a rotation direction opposite to the forward rotation direction (hereinafter referred to as the "reverse rotation direction"), sends out the rope 920 by a certain delivery length toward the car 910 side, and lowers the car 910.

[0026] Here, since the pulley provided by the elevator car 910 functions as a movable pulley, the distance the elevator car 910 rises or falls is half the length of the rope 920 that is sent out. Therefore, the control panel 950 can calculate the distance the elevator car 910 has risen or fallen from the length of the rope 920 that has been sent out. The control panel 950 also obtains the height of the elevator car 910 before it begins to rise or fall, and if the elevator car 910 rises, it adds the distance to that height, and if the elevator car 910 falls, it subtracts the distance from that height, thereby calculating the height of the elevator car 910, i.e., the position of the elevator car 910, in real time. The control panel 950 transmits the position of the elevator car 910 to the control device 911, which will be described later.

[0027] The elevator shaft PA is a passageway that includes the ascending and descending paths of the elevator car 910 and the counterweight 930, respectively. The elevator shaft PA extends vertically within a multi-story building.

[0028] (Configuration of the 910 car) As mentioned above, the elevator car 910 is equipped with a control device 911 and a speaker 912.

[0029] The control device 911 is a device that controls components of the elevator car 910, including the speaker 912, which will be described later. The control device 911 receives the position of the elevator car 910 from the control panel 950 and outputs a sound corresponding to the position of the elevator car 910 to the speaker 912. The control device 911 may also receive input from the user or inspector (worker) X of the elevator system 900, such as by pressing a button on the elevator car 910. The control device 911 may transmit the received input information (for example, the destination of the elevator car 910) to the control panel 950.

[0030] Speaker 912 receives instructions from control device 911 and outputs a sound corresponding to the position of elevator car 910. Speaker 912 may also be used to inform users of elevator system 900 of the destination of elevator car 910. In other words, speaker 912 may be a speaker that is generally provided in elevator car 910.

[0031] The sound corresponding to the position of the elevator car 910 is acquired not by a human (for example, inspector X), but by a machine (specifically, the microphone (sound acquisition unit) 130 described later). Therefore, by using the output configuration described below, the speaker 912 can reflect the position of the elevator car 910 in the sound it outputs with high accuracy.

[0032] (Output configuration of speaker 912) Speaker 912 may output sound having frequency components corresponding to the position of the elevator car 910 (output mode A). In this case, speaker 912 may use frequencies in a range that cannot be heard by the human ear as the frequency components. Speaker 912 may also change the frequency of the frequency components to a level that cannot be distinguished by the human ear, corresponding to the position of the elevator car 910. For example, if the height of the elevator car 910 is 10,000 mm, speaker 912 may output sound having a frequency component of 10,000 Hz, or it may change the frequency component by 1 Hz for every 100 mm change in the height of the elevator car 910.

[0033] Furthermore, speaker 912 may output sound for a duration corresponding to the position of the elevator car 910 (output mode B). In this case, speaker 912 may change the length of this duration to a degree that is indistinguishable to the human ear, corresponding to the position of the elevator car 910. For example, speaker 912 may change the length of this duration by 0.001 seconds for every 100 mm change in the height of the elevator car 910.

[0034] Furthermore, speaker 912 may output sound a number of times corresponding to the position of the elevator car 910 (output mode C). In this case, speaker 912 may output the sound a number of times within a time period so short that the number of times cannot be distinguished by the human ear. For example, if the height of the elevator car 910 is 10,000 mm, speaker 912 may output sound 10,000 times per second.

[0035] The above output formats A to C may be combined in any way.

[0036] These output modes allow speaker 912 to increase the types of sounds it can output and to precisely correspond the position of elevator car 910 to the sound, for example, in units of 100 mm. Therefore, speaker 912 can reflect the position of elevator car 910 in the sound it outputs with high precision. For example, speaker 912 can make the precision of the elevator car 910's position reflected in the sound higher than the precision of the voice guidance for guiding people to that position (for example, a voice announcement indicating the floor on which elevator car 910 has stopped).

[0037] <Inspection method for elevator system 900> Next, we will explain how inspector X of the elevator system 900 inspects the elevator system 900, specifically the rope 920, using the rope tester (detection unit) 110, which will be described later.

[0038] First, before starting the inspection, inspector X climbs onto the outside of the stationary elevator car 910, specifically onto the top surface of the elevator car 910.

[0039] Next, inspector X attaches the rope tester 110 to a portion of the nearby rope 920 (hereinafter referred to as the "inspection starting point") and then fixes it to the upper surface of the elevator car 910. Here, the portion of the rope 920 to which the rope tester 110 is attached may be on the side of the counterweight 930 relative to the elevator car 910, or it may be on the side that is not on the counterweight 930 side. In this embodiment, the rope tester 110 is attached to a portion of the rope 920 on the side that is not on the counterweight 930 side, as shown in Figure 1.

[0040] Finally, inspector X inputs to the control device 911 to activate the control panel 950, causing the elevator car 910 to rise or fall by a predetermined distance. While the elevator car 910 is rising or falling, the speaker 912 continues to output a sound corresponding to the position of the elevator car 910. In addition, inspector X carries an information terminal 120, which will be described later, and continues to have the information terminal 120 acquire the sound.

[0041] As shown in Figure 1, the rope tester 110 is fixed to the top surface of the elevator car 910, and therefore moves with the elevator car 910 while it is rising or descending. Thus, the rope tester 110 can inspect the rope 920 passing near the elevator car 910 over a predetermined distance from the inspection starting point.

[0042] <Configuration of Information Processing System 100> Next, the configuration of the information processing system 100 according to this embodiment will be described. The information processing system 100 uses sound to determine the location of the elevator car 910.

[0043] Figure 2 is a block diagram showing the main components of the information processing system 100 according to this embodiment. As shown in Figure 2, the information processing system 100 includes a speaker 912, a rope tester 110, and an information terminal 120.

[0044] The rope tester 110 is an inspection device that passes the rope 920 through and detects damage to the rope 920. Specifically, the rope tester 110 is configured so that the rope 920 passes through its interior, and it detects whether or not there is damage to a portion of the rope 920 inside. The rope tester 110 detects the presence or absence of damage over time as it moves along the rope 920 and outputs the detection result. The damage detected by the rope tester 110 may be any damage specified in the standard "JIS A 4302," and for example, it may be the breakage (strain breakage) or rust of the strands (the steel wires mentioned above) that make up the rope 920.

[0045] Here, the position of the elevator car 910 corresponds to a portion of the rope 920 inside the rope tester 110. Therefore, the synchronization unit 143, described later, can associate the position of the elevator car 910 with the detection result over time, i.e., synchronize them.

[0046] The information terminal 120 acquires the sound output by the speaker 912 and identifies the location of the elevator car 910. The information terminal 120 is connected to the rope tester 110 by wire or wireless connection. The information terminal 120 may be a smartphone, for example. As shown in Figure 2, the information terminal 120 includes a microphone 130, a control unit 140, and a storage unit 150.

[0047] The microphone 130 acquires sound corresponding to the position of the elevator car 910 output by the speaker 912. If the information terminal 120 is a smartphone, the microphone 130 may be a microphone that is generally provided in the smartphone.

[0048] The control unit 140 comprehensively controls the operation of each part of the information terminal 120. As shown in Figure 2, the control unit 140 includes a specific unit 141, a first notification unit 142, and a synchronization unit 143.

[0049] The identification unit 141 determines the location of the elevator car 910 based on the sound acquired by the microphone 130. The specific method of identification will be described later.

[0050] The first notification unit 142 notifies the location of the elevator car 910 identified by the identification unit 141. The specific notification method will be described later.

[0051] The synchronization unit 143 synchronizes the detection result detected by the rope tester 110 with the position of the elevator car 910 identified by the identification unit 141. The specific method of synchronization will be described later.

[0052] The storage unit 150 stores information necessary for processing performed by the information terminal 120. As shown in Figure 2, the storage unit 150 stores output format information 151.

[0053] The output mode information 151 includes information on the output mode of the speaker 912, and the correspondence between the characteristics of the sound in that output mode (e.g., frequency, length, number of repetitions) and the position of the elevator car 910.

[0054] <Information processing method M1 by information processing system 100> Next, we will explain the information processing method M1 used by the information processing system 100 when detecting damage to the rope 920 using the rope tester 110.

[0055] Figure 3 is a flowchart showing an example of the processing flow in the information processing method M1 by the information processing system 100 according to this embodiment. As shown in Figure 3, first, the speaker 912 outputs a sound corresponding to the position of the elevator car 910 of the elevator system 900 (step S11: sound output step). The speaker 912 may output the sound in one or more output modes A to C.

[0056] Next, inspector X acquires the sound output from speaker 912 using information terminal 120, and identifies the location of elevator car 910 based on the acquired sound (step S12: identification step). Specifically, identification unit 141 identifies the location of elevator car 910 based on the sound acquired by microphone 130 and output type information 151.

[0057] For example, if the speaker 912 outputs the sound in output mode A in step S11, the identification unit 141 determines the maximum frequency component of the sound and identifies the position of the elevator car 910 from the frequency of that frequency component.

[0058] Furthermore, if the speaker 912 outputs the sound in output mode B in step S11, the identification unit 141 determines the length of the sound and identifies the position of the elevator car 910 from that length.

[0059] Furthermore, if the speaker 912 outputs the sound in output mode C in step S11, the identification unit 141 determines the number of times the sound was output and identifies the position of the elevator car 910 from that number.

[0060] The identification unit 141 associates the location of the identified elevator car 910 with the time at that time and outputs it as location information for the elevator car 910.

[0061] Next, the first notification unit 142 notifies the location of the elevator car 910 identified by the identification unit 141 (step S13). The first notification unit 142 may notify by displaying the location of the elevator car 910 (for example, the height from the ground or the nearest floor) on the display of the information terminal 120, or by making the information terminal 120 ring and / or vibrate when the location of the elevator car 910 matches a preset location.

[0062] After step S13, while the elevator system 900 is being inspected, that is, while the rope tester 110 is detecting damage to the rope 920, the information processing system 100 repeats the process from step S11. After the inspection of the elevator system 900 is completed, the information processing system 100 proceeds to step S14, which is described below.

[0063] Finally, the synchronization unit 143 synchronizes the detection result detected by the rope tester 110 with the position of the elevator car 910 identified by the identification unit 141 (step S14). Specifically, the synchronization unit 143 associates the presence or absence of damage to a portion of the rope 920 that was inside the rope tester 110 at a certain time with the position information of the elevator car 910, thereby synchronizing the detection result with the position of the elevator car 910 and outputting it as synchronization information. The synchronization unit 143 may store the synchronization information in the storage unit 150. This makes it possible to associate the position of the elevator car 910 with both the position of the portion of the rope 920 where no damage was detected and the position of the portion where damage was detected.

[0064] <Summary 1> The information processing system 100 includes a speaker 912 installed in the elevator car 910 of the elevator system 900, which outputs a sound corresponding to the position of the elevator car 910, and an information terminal 120 held by inspector X, which includes a microphone 130 for acquiring the sound and an identification unit 141 for identifying the position of the elevator car 910 based on the acquired sound. As a result, the information processing system 100 can identify the position information of the elevator car 910 with a simple configuration without using special equipment such as a data recorder, because it identifies the position information of the elevator car 910 using a speaker that is generally installed in the elevator car and a microphone that is generally installed in the information terminal.

[0065] Furthermore, in the information processing system 100, the information terminal 120 is further equipped with a first notification unit 142 that notifies the location of the elevator car 910 identified by the identification unit 141. This allows the information processing system 100 to make the location of the elevator car 910 known to the inspector X.

[0066] Furthermore, the information processing system 100 is connected to an information terminal 120 and further includes a rope tester 110 that detects whether or not there is damage to the rope 920 of the elevator system 900. The information terminal 120 further includes a synchronization unit 143 that synchronizes the detection result detected by the rope tester 110 with the position of the elevator car 910 identified by the identification unit 141. As a result, the information processing system 100 can associate the location of damage to the rope 920 with the position of the elevator car 910 with a simple configuration, without using special equipment such as a data recorder.

[0067] Furthermore, the information processing method M1 includes a sound output step in which a sound corresponding to the position of the elevator car 910 of the elevator system 900 is output from a speaker 912 installed in the elevator car 910, and a identification step in which the sound is acquired by an information terminal 120 held by inspector X, and the position of the elevator car 910 is identified by the information terminal 120 based on the acquired sound. As a result, the information processing system 100 can identify the position information of the elevator car 910 with a simple configuration without using special equipment such as a data recorder, because it identifies the position information of the elevator car 910 using a speaker that is generally installed in the elevator car and a microphone that is generally equipped in the information terminal.

[0068] Furthermore, since the information terminal 120 can be a regular smartphone or similar device, the location information of the elevator car 910 can be determined with a simple configuration without the need to use special equipment such as data recorders.

[0069] [Embodiment 2] Other embodiments of this disclosure are described below. For the sake of clarity, components having the same function as those described in the above embodiments are denoted by the same reference numerals, and their descriptions are not repeated.

[0070] <Configuration of Information Processing System 100A> Figure 4 is a block diagram showing the main components of the information processing system 100A according to this embodiment. As shown in Figure 4, the information processing system 100A includes an information terminal 120A in place of the rope tester 110 and information terminal 120 in Embodiment 1. The information terminal 120A also includes a control unit 140A in place of the control unit 140 in Embodiment 1. Furthermore, the control unit 140A includes a synchronization information acquisition unit 144 and a second notification unit 145 in place of the first notification unit 142 and synchronization unit 143 in Embodiment 1.

[0071] The synchronization information acquisition unit 144 acquires synchronization information 152, which synchronizes the position of the elevator car 910 with the location of the damaged part of the rope 920 of the elevator system 900, and which was output when the elevator system 900 was inspected in the past. Here, the synchronization information 152 is the synchronization information described in Embodiment 1. The synchronization information 152 is stored in the storage unit 150 as an example. The synchronization information 152 may also be stored in an external storage device (for example, a portable storage medium) of the information terminal 120A.

[0072] The second notification unit 145 matches the position of the elevator car 910 identified by the identification unit 141 with the synchronization information 152, and notifies when the damaged area reaches a predetermined position. In this case, the predetermined position corresponds to the position of the rope tester 110 when the damaged area was detected during a previous inspection of the elevator system 900, and this corresponds to the position of the elevator car 910 at the time the damaged area was detected. The specific notification method will be described later.

[0073] <Information processing method M2 by information processing system 100A> Next, we will explain the information processing method M2 using the information processing system 100A.

[0074] Figure 5 is a flowchart showing an example of the processing flow in the information processing method M2 by the information processing system 100A according to this embodiment. As shown in Figure 5, first, the synchronization information acquisition unit 144 acquires synchronization information 152 (step S21).

[0075] Next, speaker 912 outputs a sound corresponding to the position of elevator car 910 of elevator system 900 (step S11).

[0076] Next, the microphone 130 on the information terminal 120A held by inspector X acquires the sound, and the identification unit 141 uses the information terminal 120A to identify the location of the elevator car 910 based on the acquired sound (step S12).

[0077] Next, the second notification unit 145 determines whether the damaged area has reached a predetermined location by comparing the position of the elevator car 910 identified by the identification unit 141 with the synchronization information 152 (step S22).

[0078] If the damaged area has not reached the designated location (NO in step S22), the process from step S11 is repeated. In other words, the information processing system 100A updates the position of the elevator car 910.

[0079] When the damaged area reaches a predetermined location (YES in step S22), the second notification unit 145 provides notification (step S23). The second notification unit 145 may provide notification by flashing an output device (display, light, etc.) provided by the information terminal 120A, or by making the information terminal 120A ring and / or vibrate.

[0080] In step S22, the second notification unit 145 may compare the position of the elevator car 910 plus a certain distance with the synchronization information 152. This allows the information processing system 100A to issue a notification when the damaged area approaches a predetermined position within a certain distance, and allows inspector X to stop the elevator car 910 with ample time when the damaged area reaches the predetermined position.

[0081] <Summary 2> In the information processing system 100A, the information terminal 120A further includes a synchronization information acquisition unit 144 that acquires synchronization information 152 which synchronizes the position of the elevator car 910 with the position of the damaged area of ​​the rope 920 of the elevator system 900, and a second notification unit 145 that, by comparing the position of the elevator car 910 identified by the identification unit 141 with the synchronization information 152, notifies when the damaged area reaches a predetermined position. This allows the information processing system 100A to make inspector X aware that the damaged area of ​​the rope 920, which was detected during a previous inspection of the elevator system 900, has reached a predetermined position. Furthermore, when notified, inspector X can stop the elevator car 910 and visually inspect the damaged area.

[0082] [Examples of implementation using software] The functions of the information terminals 120 and 120A (hereinafter referred to as "devices") can be realized by programs that cause the devices to function as computers, and by programs that cause each control block of the devices (especially each part included in the control units 140 and 140A) to function as a computer.

[0083] In this case, the device includes a computer having at least one control device (e.g., a processor) and at least one storage device (e.g., memory) as hardware for executing the program. By executing the program using this control device and storage device, the functions described in each of the embodiments are realized.
