This allows passengers to inform the controller of the elevator malfunction or other occurrence.

[0003] Patent document 1 discloses a technology in which, when a passenger in a car presses an emergency button to speak to an operator (controller) at a control center, if voice recognition is insufficient, a text message obtained through voice recognition is sent to the control center. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2020-66472 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, some elevator users may have difficulty explaining the fault condition through a voice call due to hearing impairment, etc. In such cases, it is preferable that when the emergency call button is pressed, a call using text messages (text call) can be made from the start to talk to a controller at the control center. On the other hand, when making a text call, it is necessary that passengers can easily input operations (answer inputs) to the text messages displayed on the display unit inside the car by using operation buttons provided on the operation unit.

[0006] Therefore, the present invention provides an elevator system and a control method for an elevator system that enable communication between elevator passengers and a controller at a control center via text conversation when an abnormality occurs in the elevator. [Means for solving the problem]

[0007] In order to solve the above problems and achieve the object of the present invention, the elevator system of the present invention is an elevator system capable of communicating with an elevator device using text information when an abnormality occurs in the elevator device. The elevator system has a fixed phrase master in which a plurality of fixed phrases corresponding to various elevator devices with different specifications are stored. The elevator system also has a fixed phrase management unit that extracts a fixed phrase suitable for the specifications of the elevator device in which the abnormality occurs from the fixed phrase master when an abnormality occurs in the elevator device. The elevator system also has a communication data transmission / reception unit that transmits and receives various data with the elevator device. When an abnormality occurs in the elevator device, the fixed phrase management unit generates answer options to be displayed on the in-car display unit of the elevator device in which the abnormality occurs based on the fixed phrases extracted from the fixed phrase master, the answer options including a plurality of answer sentences selectable by operation input from the operation unit of the elevator device in which the abnormality occurs, and the communication data transmission / reception unit transmits the answer options generated by the fixed phrase management unit to the elevator device in which the abnormality occurs.

[0008] The control method for an elevator system of the present invention extracts a fixed phrase suitable for the specifications of the elevator device in which an abnormality has occurred from a fixed phrase master that stores a plurality of fixed phrases suitable for various elevator devices with different specifications. Next, based on the fixed phrase extracted from the fixed phrase master, answer options are generated that are displayed on an in-car display unit of the elevator device in which an abnormality has occurred and include a plurality of answer sentences that can be selected by operation input from an operation unit of the elevator device in which an abnormality has occurred. Then, the generated answer options are transmitted to the elevator device in which an abnormality has occurred via a communication data transmitting / receiving unit. Effect of the Invention

[0009] According to the present invention, when an abnormality occurs in an elevator, communication between passengers and a controller at a control center can be carried out by a simple operation via text conversation. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, an example of an elevator system and a control method for an elevator system according to an embodiment of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the following example. In each of the drawings described below, the same reference numerals are used to denote common parts.

[0012] 1. Elevator System Configuration Fig. 1 is a diagram showing an example of an elevator system 1 according to an embodiment of the present invention (hereinafter, referred to as the present embodiment). The elevator system 1 of the present embodiment is composed of an elevator device 10 installed in a building 100, an elevator monitoring device 30 provided in the building 100 in which an elevator 20 is installed, and a control system 40 installed in a control center 200 in a building other than the building 100. Note that the elevator system of the present invention may be composed of a part of the elevator system 1 shown in Fig. 1, or may be composed of the entire elevator system 1.

[0013] [Elevator equipment] The elevator system 10 is composed of an elevator 20 consisting of a car 140 and a hoist (not shown) that raises and lowers the car 140, and an elevator control unit 160 that controls the elevator 20.

[0014] The elevator 20 has a car 140 provided in the hoistway, and also has a main rope with one end attached to the car 140 and a counterweight to which the other end of the main rope is attached and suspended in the hoistway (not shown). The elevator 20 also has a hoist around which the main rope is wound. The hoist is rotatably installed, for example, in a machine room provided at the top of the hoistway. The hoist is controlled and driven by an elevator control unit 160. As a result, the car 140 rises and falls relative to the counterweight.

[0015] The elevator control unit 160 is electrically connected to the elevator monitoring device 30, and controls each unit of the elevator device 10 based on signals from the elevator monitoring device 30. For example, the elevator control unit 160 controls and drives the hoisting machine to raise and lower the car 140. Furthermore, the elevator control unit 160 controls the opening and closing operation of a door unit (not shown) according to a predetermined timing. The elevator control unit 160 also controls the operation unit 150 and the in-car display unit 130 installed in the car 140. Furthermore, in this embodiment, the elevator control unit 160 controls the input and output of the operation unit 150 and the in-car display unit 130.

[0016] The operation unit 150 is attached in a position inside the car 140 where it can be operated by passengers. Fig. 2 is an enlarged view of the operation unit 150 of this embodiment. As shown in Fig. 2, the operation unit 150 includes destination floor buttons 152a and 152b for inputting a predetermined destination floor, an open button 154 and a close button 153 for inputting an operation to open or close the car door, and an emergency call button 151.

[0017] The destination floor buttons 152a, 152b are push-type and / or sensor-type input units provided for a predetermined number of floors (two floors in this embodiment) according to the stopping floors of the elevator device 10. The passenger 300 can register a destination floor by operating the destination floor buttons 152a, 152b.

[0018] The open button 154 and the close button 153 are input units that can operate the opening and closing operation of the door unit. By operating the open button 154 and the close button 153, the passenger 300 can operate the opening and closing operation of the door unit when the elevator car 140 is stopped at a predetermined stop floor.

[0019] The emergency call button 151 is an input unit operated by the passenger 300 in an emergency such as when an abnormality occurs in the elevator 20. By operating the emergency call button 151, the passenger 300 can start input operations in an emergency. In this embodiment, the input operations of the passenger 300 in an emergency are characterized. The input operations in an emergency will be described in detail later.

[0020] The car interior display unit 130 is, for example, a monitor configured with an LCD (Liquid Crystal Display) or the like, and during normal operation, displays the floor the car 140 is passing through and the next floor to stop at, etc. In this embodiment, after pressing the emergency call button 151, a screen that the passenger 300 can input information on and a two-dimensional code transmitted from the control center 200, which will be described later, are displayed.

[0021] Although not shown, a communication device capable of voice communication with the control center 200 is provided inside the car 140. By using the communication device, voice communication is possible between the passengers 300 and the controller 500 of the control center 200 in an emergency, as necessary.

[0022] [Elevator monitoring device] The elevator monitoring device 30 includes a monitoring control unit 120 and a communication device 110.

[0023] The monitoring control unit 120 is electrically connected to an elevator control unit 160 of the elevator device 10, and transmits control signals for controlling each part of the elevator device 10 to the elevator control unit 160 side, and receives signals transmitted from the elevator control unit 160 side. The monitoring control unit 120 also transmits and receives communication data with the control system 40 provided in the control center 200 via the communication device 110. The monitoring control unit 120 controls each part constituting the elevator monitoring device 30 based on signals transmitted from the control system 40 and the elevator control unit 160.

[0024] The communication device 110 is connected to the control system 40 via a general public line network 400 such as a network. In this embodiment, when the emergency call button 151 is pressed, various information of the elevator device 10 is transmitted to the control center 200 via the communication device 110. When the emergency call button 151 is pressed and it is determined that a call with the control center 200 is necessary, a call is made between the passenger 300 in the car 140 and the controller 500 of the control center 200 from a communication device (not shown) in the car 140 via the communication device 110.

[0025] [Elevator control system] The control system 40 installed in the control center 200 is made up of a communication data transmitting / receiving unit 210 , a control terminal 220 , an elevator master 230 , a fixed phrase management unit 240 , and a fixed phrase master 250 .

[0026] The communication data transmitting / receiving unit 210 is connected to the communication device 110 of the elevator monitoring device 30 via a general public line network 400 such as a network. The communication data transmitting / receiving unit 210 receives various data transmitted from the elevator monitoring device 30 side, and transmits data input from the control terminal 220 to the elevator monitoring device 30 side.

[0027] The control terminal 220 is a terminal device that can be operated by the controller 500, and is configured, for example, by a personal computer. The control terminal 220 has a display unit that displays text messages based on signals transmitted from the elevator monitoring device 30 side and text messages generated by the fixed phrase management unit 240 described below, and an operation unit that can be operated by the controller 500. The controller 500 appropriately selects the text message displayed on the display unit from the control terminal 220. As a result, the text data selected by the control terminal 220 is transmitted to the elevator monitoring device 30 side by the operation of the controller 500.

[0028] The elevator master 230 is a database that stores various data related to the elevator device 10 managed by the control center 200. For example, the identification number of the elevator 20, the specifications of the elevator 20, the address of the building 100 in which the elevator 20 is installed, etc. are stored.

[0029] The standard phrase master 250 is a database that stores a plurality of text messages (standard phrases) to be sent to the elevator 20 for which the emergency call button 151 has been pressed when an abnormality occurs in the elevator 20. The specifications of the elevator 20, such as the number of stopping floors (floor information) and the number of operation buttons in the operation unit 150, vary from elevator to elevator. The standard phrase master 250 stores standard phrases suitable for various elevators 20 with different specifications. An example of a standard phrase stored in the standard phrase master 250 will be described in detail later.

[0030] The fixed phrase management unit 240 extracts a fixed phrase suitable for the specifications of the elevator 20 whose emergency call button 151 has been pressed from the fixed phrase master 250 based on an instruction from the control terminal 220. Furthermore, when an abnormality occurs in the elevator device 10, the fixed phrase management unit 240 generates answer options M2 (see FIG. 6A) to be displayed on the car interior display unit 130 of the elevator 20 whose emergency call button 151 has been pressed, based on the fixed phrase extracted from the fixed phrase master 250. The answer options M2 are text messages displayed on the car interior display unit 130 to prompt an answer from the passenger 300, and are composed of a plurality of answer sentences selectable by operation input from the operation unit 150 of the elevator 20 whose emergency call button 151 has been pressed. An example of the answer options M2 generated by the fixed phrase management unit 240 will be described in detail later.

[0031] The functional configurations of the elevator system 1 of this embodiment have been described above. These functional configurations are realized by information processing devices (hardware) such as a microcontroller constituting each device or system. The information processing device includes, for example, a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and a non-volatile storage, each of which is connected to a bus.

[0032] The CPU reads out the program code of the software that realizes each function according to the present embodiment from the ROM, and expands it in the RAM and executes it in each system or each device that constitutes each system. Note that the information processing device may include a processing device such as an MPU (Micro-Processing Unit) instead of the CPU. Variables, parameters, etc. that are generated during the calculation process are temporarily written to the RAM.

[0033] Examples of non-volatile storage that can be used include a hard disk drive (HDD), a solid state drive (SSD), a flexible disk, an optical disk, a magneto-optical disk, a CD-ROM, a CD-R, a magnetic tape, and a non-volatile memory card. In addition to an operating system (OS), programs and data required for the CPU to operate are stored in this non-volatile storage. The non-volatile storage corresponds to a memory unit (not shown) configured in the elevator system 1. The programs may be stored in a ROM.

[0034] The program is stored in the form of a program code that can be read by the CPU, and the CPU sequentially executes operations according to the program code. In other words, a ROM or non-volatile storage is used as an example of a non-transitory recording medium that can be read by the CPU and stores a program to be executed by the CPU.

[0035] 2. Elevator system control method Next, a control method for the elevator system 1 in this embodiment will be described. Fig. 3 is a flowchart showing a control method implemented by the elevator monitoring device 30 and the elevator device 10 of the elevator system 1 of this embodiment when the emergency call button 151 is pressed. Fig. 4 is a flowchart showing a control method implemented by the control system 40 when the emergency call button 151 is pressed.

[0036] The flowchart in Fig. 3 starts when a passenger 300 in the car 13 presses the emergency call button 151 provided on the operation unit 150. That is, the flowchart in Fig. 3 starts when an emergency call signal generated by pressing the emergency call button 151 is transmitted to the monitoring control unit 120 via the elevator control unit 160.

[0037] As shown in FIG. 3, when the emergency call button 151 is pressed, the monitor control unit 120 displays a call mode selection screen on the car interior display unit 130 via the elevator control unit 160 (step S1).

[0038] Fig. 5 is an example of a display screen displayed on the car in-display unit 130 in step S1. As shown in Fig. 5, options for the call mode include a "voice call mode" in which a call is made directly by voice to the controller 500 at the control center 200 using a communication device in the car 140 (not shown), and a "text call mode" in which a call is made to the controller 500 by a text message displayed on the car in-display unit 130. The car in-display unit 130 displays, for example, a message M01 saying "Connecting to the control center. Please select your desired call method," and an operation display field M02 showing an operation method for entering the selected mode.

[0039] 4 shows an example in which the operation display field M02 displays respective operation methods such that when the "voice call mode" is selected, the open button 1154 on the operation unit 150 is pressed, and when the "text call mode" is selected, the close button 153 on the operation unit 150 is pressed. The passenger 300 selects the call mode by inputting from the open button 154 or the close button 153 according to the display screen displayed on the car interior display unit 130.

[0040] The monitoring control unit 120 judges whether or not a call mode has been input from the operation unit 150 in the car 140 (step S2 in FIG. 3). If it is judged in step S2 that the open button 154 has been pressed, the process proceeds to step S10. On the other hand, if it is judged in step S2 that the close button 153 has been pressed, the process proceeds to step S3. At this time, the monitoring control unit 120 transmits information on the selected call mode to the control system 40 side via the communication device 110.

[0041] At this time, in the control system 40, the control terminal 220 determines whether the call mode transmitted from the elevator monitoring device 30 is the "voice call mode" or the "text call mode" (step S11 in FIG. 4). If it is determined in step S11 that the call mode transmitted is the "voice call mode", the process proceeds to step S20. On the other hand, if it is determined in step S11 that the call mode transmitted is the "text mode", the process proceeds to step S12.

[0042] In step S10 in FIG. 3 and step S19 in FIG. 4, a voice call is started between the controller 500 and the passenger 300. The voice call is performed by communication devices (not shown) on the control center 200 side and on the elevator 20 side. For example, the passenger 300 in the car 140 can make a call with the controller 500 via a microphone and a speaker provided in the car 140. When the voice call is performed, the controller 500 can end the voice call by, for example, disconnecting the communication. When the voice call is interrupted, the flowcharts in FIG. 3 and FIG. 4 end.

[0043] On the other hand, in step S2 of FIG. 3, if the passenger 300 selects the “text call mode”, the monitoring control unit 120 transmits elevator information including the identification number of the elevator 20 to the control system 40 via the communication device 110.

[0044] As a result, on the control system 40 side, as shown in step S12 of FIG. 4, the communication data transmitting / receiving unit 210 receives the elevator information from the elevator monitoring device 30 side.

[0045] On the control system 40 side, as shown in step S13 of Fig. 4, the control terminal 220 extracts various information of the corresponding elevator 20 from the elevator master 230 based on the elevator information received by the communication data transmitting / receiving unit 210. The extracted information of the elevator 20 includes destination floor information indicating floors at which the corresponding elevator 20 can stop.

[0046] Next, on the control system 40 side, as shown in step S14 of Fig. 4, under the instruction of the control terminal 220, the fixed phrase management unit 240 extracts a fixed phrase suitable for the corresponding elevator 20 from the fixed phrase master 250. The fixed phrase constitutes the answer sentence m (see Fig. 6A) of the answer option M2 to be transmitted from the control terminal 220 to the elevator monitoring device 30 in the next step S15.

[0047] Here, in step S14, the fixed phrase management unit 240 extracts fixed phrases suitable for the specifications of the corresponding elevator 20 based on the destination floor information (information on the floors at which the elevator 20 stops) extracted in step S13. For example, if the destination floors of the corresponding elevator 20 are the first and second floors, fixed phrases corresponding to elevators that stop at the first and second floors are extracted. The details of the fixed phrases will be described later.

[0048] Next, the fixed phrase management unit 240 generates answer options M2 corresponding to the response message M1 based on the extracted fixed phrase, and outputs them to the control terminal 220 (step S15 in FIG. 4). Here, the response message M1 is extracted and generated in a response message generation unit (not shown) of the control terminal 220. The response message M1 is a message for responding to an inquiry or answer transmitted from the elevator monitoring device 30, and is extracted on the control terminal 220 side, for example, from a storage unit (not shown).

[0049] Fig. 6A shows an example of a display screen displayed on the display unit 221 of the control terminal 220 in step S15. As shown in Fig. 6A, the display unit 221 of the control terminal 220 displays elevator information I1 of the corresponding elevator 20, a transmittable response message M1, and a check box b for selecting the response message M1 to be transmitted. Furthermore, the display unit 221 of the control terminal 220 displays a transmission button S1 and an answer option M2 that will be displayed in the option display field 131 (see Fig. 7A) of the car interior display unit 130 of the corresponding elevator 20 when the selected response message M1 is transmitted.

[0050] For example, when the text call mode is selected to start a text call after the emergency call button 151 is pressed, the response message generation unit extracts a response message M1 saying, "This is the control center. What can I do for you?" as shown in Fig. 6A. The fixed phrase management unit 240 generates answer options M2 including answer sentences m suitable for answering the response message M1 based on the fixed phrases extracted from the fixed phrase master 250. Then, the control terminal 220 displays the answer options M2 sent from the fixed phrase management unit 240 on the display unit 221 of the control terminal 220 together with the elevator information I1 of the corresponding elevator 20 and the response message M1.

[0051] As shown in FIG. 6A, elevator information I1 displayed on display unit 221 of control terminal 220 is elevator information extracted from elevator master 230, and includes "customer number," "building code," "building name," "car number," and "destination floor."

[0052] Incidentally, when text messages have already been exchanged with passenger 300 through steps S16 and S17 described below, a response message according to the content of the reply or inquiry from passenger 300 is extracted and displayed in control terminal 220 (response message generating unit) each time (e.g., FIG. 6B, etc.). In this embodiment, response message M1 is extracted from data stored in the memory unit on the control terminal 220 side, but it may be extracted from data stored in fixed phrase master 250, like the fixed phrases constituting answer option M2.

[0053] In FIG. 6A, one response message M1 can be selected using the check box b, but if multiple selectable response messages are extracted by the controller 500, as in FIG. 6B and FIG. 6C described below, two or more can be displayed.

[0054] Here, multiple answer sentences m to the selected response message M1 are displayed in the answer option M2. Each answer sentence m constituting the answer option M2 is composed based on a fixed phrase extracted from the fixed phrase master 250, and each includes an explanation of the event and information on an operation button to be pressed when selecting the event.

[0055] FIG. 6A shows an answer option M2 to be sent to the elevator 20, which can stop at two destination floors, the first floor and the second floor. In this case, three selectable answer sentences m are displayed. Each answer sentence m includes an explanation of the event and information on the operation button to be pressed when selecting the event. For example, the text explaining the event "I'm locked in" is associated with the destination floor button 152a for the first floor. Also, the text explaining the event "I heard an abnormal noise" is associated with the destination floor button 152b for the second floor. On the other hand, as a case that does not fit either of the above two events, the text "Other (Next)" is displayed, and the open button 154 is associated with the text. When the open button 154 is pressed, the screen is scrolled, and an answer sentence including an explanation of a different event and information on the operation button to be pressed when selecting the event is displayed again.

[0056] Incidentally, in the elevator device 10, the number of operation buttons provided on the operation unit 150 in the elevator car 140 varies depending on the number of destination floors at which the elevator can stop. Therefore, in a text call, when a response message M1 from the control center 200 side is displayed on the car interior display unit 130 and a response to the response message M1 is selected from the answer option M2 in the option display field 131 of the car interior display unit 130 and input from the operation unit 150, the number of answer sentences m displayed in the option display field 131 must be set to be equal to or less than the number of operation buttons of the operation unit 150. In this embodiment, the answer sentences m constituting the answer option M2 are composed of fixed phrases extracted from the fixed phrase master 250 based on the elevator information (floor information). As a result, the number of answer sentences m constituting the answer option M2 is set to be equal to or less than the number of operation buttons of the operation unit 150 of the corresponding elevator 20.

[0057] When the controller 500 checks the check box b, the answer option M2 displayed in the option display field 131 of the car interior display unit 130 in response to the response message M1 can be confirmed on the display unit 221 of the control terminal 220. When the controller 500 checks the check box b and selects the send button S1, the response message M1 and the answer option M2 for the response message M1 are sent to the elevator monitoring device 30.

[0058] Next, the control terminal 220 judges whether or not the send button S1 has been pressed (step S16 in FIG. 4). If it is judged that the send button S1 has not been pressed, the judgment of step S16 is repeated. On the other hand, if it is judged in step S16 that the send button S1 has been pressed, the process proceeds to step S17. In step S17, text information including the transmitted response message M1 and the answer option M2 corresponding to the response message M1 is transmitted to the corresponding elevator monitoring device 30.

[0059] On the elevator monitoring device 30 side, the monitoring control unit 120 receives the information of the response message M1 and answer options M2 transmitted from the control system 40 via the communication device 110 (step S4 in FIG. 3). Then, the monitoring control unit 120 displays the response message M1 and answer options M2 received from the control system 40 side on the car internal display unit 130 via the elevator control unit 160 (step S5 in FIG. 3). FIG. 7A is an example of a display screen displayed on the car internal display unit 130 when the response message M1 shown in FIG. 6A is selected and transmitted.

[0060] As shown in Fig. 7A, the car interior display unit 130 displays the response message M1 selected in Fig. 6A together with a text message M11 saying "You are in a text call with the control center. Please respond using the door open / close button and destination floor button in the car." Furthermore, the answer option M2 transmitted from the control system 40 side is displayed in the option display field 131 of the car interior display unit 130. At this time, the monitoring control unit 120 may be configured to blink the operation button associated with the answer option M2 via the elevator control unit 160.

[0061] The passenger 300 can check each text message in FIG. 7A displayed on the car interior display unit 130, and can input his / her own response using each button on the operation unit 150. For example, if a person is trapped, he / she presses the destination floor button 152a for the first floor. Also, if an abnormal noise is heard, he / she presses the destination floor button 152b for the second floor. If there is some other abnormality, he / she can change the option display in the option display field 131 by pressing the open button 154.

[0062] Fig. 7B shows an example of a display screen displayed on the car interior display unit 130 when the open button 154 is pressed. As shown in Fig. 7B, when the open button 154 is pressed on the screen of Fig. 7A, other events such as "There was a problem opening and closing the door" and "There was a lost item" are displayed as answer options in the option display field 131. In this case as well, answer sentences within the number range selectable by the button of the operation unit 150 are displayed in the option display field 131 of the car interior display unit 130.

[0063] Next, the monitoring control unit 120 judges whether the input of the answer from the passenger 300 is completed based on the input signal from the operation unit 150 (step S6 in FIG. 3). FIG. 7C is an example of a display screen displayed on the car interior display unit 130 when the passenger 300 presses the destination floor button 151a for the first floor according to the display screen of the car interior display unit 130 shown in FIG. 7A. In FIG. 7C, a response message M12 saying "···· has been selected. Is this OK?" is displayed, and an answer option M13 to the response message M12 is displayed in the option display field 131. In the answer option M13, for example, when "Yes" is input, a display is made to press the close button 153. On the other hand, when "No" is input, a display is made to press the open button 154. Note that these response messages M12 and answer options M13 may be displayed based on data transmitted from the control system 40 side, or may be displayed based on data generated by the monitoring control unit 120.

[0064] 7, when the close button 153 is pressed and "Yes" is input, the monitoring control unit 120 determines that input of the answer from the passenger 300 is completed. Then, the information of the selected answer sentence is transmitted to the control system 40 (step S7 in FIG. 3).

[0065] Next, the control system 40 determines whether or not to end the text call based on the response information transmitted in step S7 in Fig. 3 (step S18 in Fig. 4). For example, if the presentation of a countermeasure method to the passenger 300 in the car 140 has been completed and text call with the passenger 300 is not necessary, the control system 220 does not continue the text call in step S18 and ends the text call. On the other hand, if it is determined that a text call with the passenger 300 is necessary, such as when the presentation of a countermeasure method to the passenger in the car 140 has not been completed, the control terminal 220 determines to continue the text call and returns to step S15.

[0066] 6B and 6C show an example of a display screen displayed on the display unit 221 of the control terminal 220 again when it is determined in step S18 of FIG. 4 that the text call is to be continued. For example, this is a display screen displayed on the display unit 221 of the control terminal 220 when a response of "I heard an abnormal sound" is input from the elevator device 10. As shown in FIG. 6B, the controller 500 can select a response message M3 saying "We will now dispatch an engineer to the site. Please stay calm and wait" or a response message M4 saying "Where did you hear the abnormal sound?" These response messages M3 and M4 are also extracted by the control terminal 220, similar to the response message M1.

[0067] Depending on whether the controller 500 selects the response message M3 or the response message M4, the answer options M5 and M6 displayed in the option display field 131 of the car interior display unit 130 change. As with the answer option M2, these answer options M5 and M6 are also generated in the template management unit 240 so as to correspond to the respective response messages M3 and M4.

[0068] On the control terminal 220 side, as shown in Figures 6B and 6C, by checking the checkbox b, the contents of each answer option M5, M6 displayed in the option display column 131 of the car interior display unit 130 when the response message M3 or M4 is sent can be confirmed.

[0069] Then, the control system 40 transmits the response message and the answer option selected by the controller 500 in the same manner as in steps S16 and S17.

[0070] On the other hand, if the result of the determination in step S18 is "YES", that is, if the control terminal 220 determines that the text call is to be ended, the process proceeds to step S19. In step S19, it is determined whether or not an end call operation has been performed by input from the controller 500. If it is determined that an end call operation has not been performed, the determination in step S20 is repeated. On the other hand, if it is determined that an end call operation has been performed, the flow chart in FIG. 4 ends.

[0071] On the other hand, on the elevator monitoring device 30 side, after step S7 in Fig. 3, the monitoring control unit 120 judges again whether or not a response message and a text message consisting of answer options corresponding to the response message have been transmitted from the control system 40 side (step S8 in Fig. 3). If a text message has been transmitted again to the corresponding elevator device 10 side in step S16 in Fig. 4, the judgment in step S8 is "YES". If the judgment in step S8 is "YES", that is, if a text message has been transmitted again from the control system 40, the process returns to step S5, and steps S5 to S8 are repeated.

[0072] In this case, for example, the text message shown in Fig. 6B or 6C is displayed in the option display field of the car interior display unit 130. The passenger 300 can input an appropriate answer by operating each operation button of the operation unit 150 according to the display screen of the car interior display unit 130.

[0073] On the other hand, if the result of step S8 is "NO", that is, if the monitoring and control unit 120 determines that a text message has not been received from the control system 40, the process proceeds to step S9.

[0074] In step S9, it is determined whether or not a call-ending operation has been performed based on a signal transmitted from the control system 40. If the determination in step S9 is "NO," the process returns to step S8 again. On the other hand, if the determination in step S9 is "YES," that is, if it is determined that a call-ending operation has been performed, the monitoring control unit 120 returns the display on the car interior display unit 130 to the normal mode via the elevator control unit 160, and ends the flowchart in FIG. 4.

[0075] In this manner, in this embodiment, when an abnormality occurs in the elevator 20 and the emergency call button 151 is pressed, the passenger 300 can select whether to communicate with the controller 500 of the control center 200 by text communication or voice communication. In addition, when the passenger 300 selects text communication, the control system 40 extracts from the standard phrase master 250 a standard phrase suitable for display on the car display unit 130 of the elevator 20 based on the specifications of the corresponding elevator 20. This allows standard phrases that can be answered by inputting from the operation buttons of the operation unit 150 provided in the car 140 to be displayed on the car display unit 130 according to the specifications of the corresponding elevator 20. This allows the passenger 300 to input an answer by pressing the operation button of the operation unit 150 associated with a desired option from among the answer options displayed in the option display field 131 of the car display unit 130.

[0076] 3. When there are four destination floors Here, a case where the number of destination floors of the elevator 20 is four will be described. Fig. 8 is a schematic configuration diagram of an operation unit 650 provided in the car 140 of the elevator 20 having four destination floors. As shown in Fig. 8, the operation unit 650 has destination floor buttons 152a, 152b, 152c, 152d for inputting a predetermined destination floor, an open button 154 and a close button 153 for inputting an operation for opening and closing the car door, and an emergency call button 151. That is, the operation unit 650 has six operation buttons in addition to the emergency call button 151.

[0077] Fig. 9 is a diagram showing an example of a display screen displayed on the car interior display unit 130 when the emergency call button 151 is pressed and text communication is selected in step S2 of Fig. 3 in the elevator 20 equipped with the operation unit 650 shown in Fig. 8. The car interior display unit 130 displays the response message M1 selected in step S16 of Fig. 4 together with a text message M11 saying "A text call with the control center is in progress. Please respond using the door open / close button and destination floor button in the car." Furthermore, the option display field 131 of the car interior display unit 130 displays an answer option M23 consisting of a fixed phrase extracted from the fixed phrase master 250 in the control system 40.

[0078] As shown in FIG. 9, when the operation unit 650 has four destination floor buttons 151a to 151d, the answer option M23 displayed in the option display field 131 is composed of four selectable answer sentences. Each answer sentence includes an explanation of the event and information on an operation button to be pressed when selecting the event. For example, the text explaining the event "I'm locked in" is associated with the destination floor button 152a for the first floor as an operation button. Also, the text explaining the event "I heard an abnormal noise" is associated with the destination floor button 152b for the second floor as an operation button. Also, the text explaining the event "There was a problem opening and closing the door" is associated with the destination floor button 152c for the third floor as an operation button. Also, the text explaining the event "There was a lost item" is associated with the destination floor button 152d for the fourth floor as an operation button.

[0079] The passenger 300 selects an appropriate option from the option display field 131 of the car interior display unit 130 shown in Fig. 9 and presses the corresponding operation button. This causes a screen similar to that shown in Fig. 7C to be displayed, and the passenger can input "Yes" or "No" using the operation button to transmit the answer to the control system 40.

[0080] In this manner, in this embodiment, an optimal template is extracted from the template master according to the number of operation buttons on the operation unit, and answer options consisting of answer sentences generated based on the template are displayed on the car internal display unit. As a result, answer options consisting of multiple answer sentences suitable for the specifications of the corresponding elevator are displayed on the car internal display unit, and passengers can select the desired template by pressing the operation button corresponding to the answer sentence of their choice.

[0081] In the present embodiment, when a passenger in the elevator 140 selects text communication, a call with the controller 500 in the control center 200 is made only by sending and receiving text information, but the present invention is not limited to this. The controller 500 in the control center 200 can start a voice call as necessary even when a text call is being made with the passenger 300 in the elevator 140.

[0082] Also, when it is determined that a text call is necessary during a voice call, the controller 500 may be configured to transmit a text message consisting of a response message and answer options to the elevator device 10. In this case, the answer options are also composed of fixed phrases extracted from a fixed phrase master. In this way, when a text call is made between the elevator device and the control center, appropriate answer options are displayed on the display unit inside the car, making it possible to perform an input operation from the operation unit 150 of the corresponding elevator device 10.

[0083] In this embodiment, communication can be achieved between passengers in the elevator car and the controller at the control center by text calling. This allows smooth communication with the controller 500, even if a person with hearing impairment or who cannot speak presses the emergency call button 151, as text calling can be performed between the control center 200 and the passenger.

[0084] The above-mentioned embodiment has been described in detail to clearly explain the present invention, and is not necessarily limited to having all of the configurations described. For example, it is possible to replace a part of the configuration of the embodiment with another configuration, and it is also possible to add another configuration to the configuration of the embodiment. Also, it is possible to add, delete, or replace a part of the configuration of the embodiment with another configuration. [Explanation of symbols]
