The state in which the maintenance worker returns from the pit to the platform on the lowest floor after the maintenance work in the pit is completed is called the pit-out state. After checking, it is preferable to lower the car toward the lowest floor. For this reason, it is necessary for the maintenance worker inside the car to recognize the pit-out state on the lowest floor side.

One method is to turn on the pit lights when performing maintenance work inside the pit to brighten up the dark interior of the pit. Make sure the lights are turned off. Although this method is simple, in the case of a high-rise elevator, if the pit and the car are far apart, it becomes difficult to see the pit side through the gap between the car entrance and the hoistway. Even in that case, it is conceivable to communicate using a wireless telephone or the like, but depending on the environment of the hoistway, wireless communication may be difficult.

As described in Patent Document 3, it is conceivable to use a technology in which the control device recognizes a pit-out when a landing button on the lowest floor is pressed a predetermined number of times within a predetermined time. A third party other than the worker may perform similar operations. In the example of Patent Document 3, if a third party, such as a passenger on the bottom floor landing or a building cleaning staff, presses the button four times within 10 seconds, the control device mistakenly assumes that the pit is out. do.

Therefore, there is a need for an elevator pit out communication support method and an elevator pit out communication support system that can suppress misidentification of a pit out state and communicate between cars in the pit and on a floor remote from the pit.

The operation of the car 40 in the maintenance mode is controlled by a maintenance lift operation button provided on the maintenance work panel 54. Instead of the maintenance lift operation button, a maintenance terminal connection interface (not shown) may be provided on the maintenance work panel 54, a maintenance terminal may be connected to this, and the operation of the car 40 may be controlled by operating the maintenance terminal.

The remote communication mode button 58 allows remote communication between the pit-side maintenance worker 4 and the car-side maintenance worker 6 to be performed using equipment already provided in the high-rise elevator system 10 in the maintenance mode. This is an operation button to switch to remote contact mode, which allows remote contact. Under simple maintenance mode, communication regarding the pit-out status between the pit-side maintenance worker 4 and the car-side maintenance worker 6 would be done by visual confirmation that the pit lights are off or by radio telephone, etc. , remote contact mode is used when these contact methods are difficult.

Remote contact mode button 58 can be operated only when high-rise elevator system 10 is in maintenance mode. That is, when the car-side maintenance worker 6 presses the remote communication mode button 58 once while the display surface of the maintenance mode button 56 is lit, the display surface of the remote communication mode button 58 becomes lit, and the control device 60 is turned on. Control switches to remote contact mode. When the car-side maintenance worker 6 presses the remote communication mode button 58 one more time, the display surface of the remote communication mode button 58 returns to the off state, the remote communication mode is canceled, and the mode returns to the maintenance mode. When the maintenance mode button 56 is operated to return from the maintenance mode to the normal mode while the remote communication mode button 58 is lit, the display surface of the remote communication mode button 58 is turned off together with the display surface of the maintenance mode button 56.

The equipment used in the communication support system 70 in the high-rise elevator system 10 communicates with the pit-side maintenance worker 4 who has finished maintenance work in the pit 16, and the car-side maintenance worker 6 who is in the car 40 stopped on the 40th floor. It is a device for communicating between. There are roughly three types of communication between the pit-side maintenance worker 4 and the car-side maintenance worker 6.

The first communication is a pit-out state notification that informs the car-side maintenance worker 6 that the pit-side maintenance worker 4 has entered the pit-out state. The pit-out state is a state in which the pit-side maintenance worker 4 has finished the maintenance work in the pit 16 and has returned from the pit 16 to the landing 30 on the first floor.

The second communication is a confirmation communication in which the pit-side maintenance worker 4 receives a confirmation signal from the car-side maintenance worker 6 who has received the pit-out status notification to the effect that "pit-out notification has been received."

The third communication is a notification communication in which the pit-side maintenance worker 4 notifies the car-side maintenance worker 6 that "the confirmation message has been received." When the car-side maintenance worker 6 receives the notification, control is performed to lower the car 40 toward the landing 30 on the first floor for the first time.

The devices for making these communications are the pit-side communication input/output device 50 and the illumination meter 28 in the landing 30 on the first floor, and the car-side communication input/output device 52 in the car 40. The pit-side communication input/output device 50 uses the landing button 34 included in the car call panel 32 used for car calls in the normal mode as a communication input device, and uses the elevation status display section 36 as a communication output device. The car-side communication input/output device 52 uses the destination floor indicator panels 44 and 45, which are used to indicate the destination floor of the car 40 in the normal mode, as communication input devices, and uses the notification units 46 and 47 for emergency communication as communication output devices. used as The left and right destination floor indicator boards 44, 45 have the same configuration, and the left and right notification units 46, 47 have the same configuration, so the destination floor indicator board 44 and notification unit 46 will be explained below.

A light-off signal from the illumination meter 28 is also used to notify the pit-out state. After finishing the maintenance work in the pit 16, the pit-side maintenance worker 4 turns off the in-pit illumination light 26. As a result, the illuminance meter 28 outputs a lights-out signal, but just because the illuminance meter 28 outputs the lights-out signal does not necessarily mean that the pit-side maintenance worker 4 has returned to the landing 30 on the first floor. After turning off the pit illumination light 26, the pit-side maintenance worker 4 exits from the pit 16 to the landing 30 on the first floor using a suitable means such as a ladder, and manually closes the landing door. The pit-side maintenance worker 4 then returns to the landing 30 on the first floor and enters the pit-out state. Therefore, to notify the pit-out status, a light-off signal from the illumination meter 28 and, in some cases, a signal indicating that the landing door on the first floor is in a closed state are used together, and then the pit-side maintenance worker 4 It is necessary to indicate that you have returned to the landing 30.

If an authentication device for maintenance workers is provided in advance at the landing 30 on the first floor, when the identification data of the pit-side maintenance worker 4 is authenticated by the authentication device, the button 34 on the bottom floor is pressed. The generated signal can be transmitted to the car-side maintenance worker 6. As the authentication device, a device that authenticates the identification data of the maintenance worker's employee ID card, etc. can be used.

If the authentication device is not provided, the landing button 34 of the car call panel 32 in the landing 30 on the first floor is used by the pit-side maintenance worker 4 as an input device for a signal indicating the pit-out state. A simple operation of the landing button 34 cannot be distinguished from a case where a third party other than the pit-side maintenance worker 4 operates the landing button 34, so the operation of the landing button 34 on the car call panel 32 is a predetermined pit exit. This is done by outputting a signal. The contents of the predetermined pit-out signal will be described later. The button signal line 84 is then used as the remote communication signal line 80 to transmit the pit-out signal to the remote communication mode control block 104 (see FIG. 5) of the controller 60. Since the lights-off signal is transmitted from the illuminance meter 28 using the illuminance signal line 82 as the remote communication signal line 80, the control device 60 creates notification data indicating the pit-out state based on the lights-off signal and the pit-out signal. do. The created notification data is transmitted to the notification section 46 of the car 40 using the notification signal line 96 as the remote communication signal line 90. The car-side maintenance worker 6 receives notification that the pit-side maintenance worker 4 is out of the pit, using the notification section 46 as an output device for notification data.

For the confirmation communication, the car-side maintenance worker 6 uses the destination floor indication panel 44 as an input device for a confirmation signal indicating that the pit-out status notification has been received, and uses the destination floor indication signal line 94 as the remote communication signal line 90. The information is transmitted to the control device 60. The control device 60 creates appropriate display data based on the confirmation signal. The created display data is transmitted to the elevator status display section 36 of the car call panel 32 of the landing 30 on the first floor using the display signal line 86 as the remote communication signal line 80. The pit-side maintenance worker 4 receives the confirmation signal transmitted by the car-side maintenance worker 6 using the elevation status display section 36 as an output device for display data.

For the notification communication, the pit-side maintenance worker 4 uses the landing button 34 of the car call panel 32 in the landing 30 on the first floor as an input device for the reception signal indicating that the confirmation signal has been received. Then, using the button signal line 84 as the remote communication signal line 80, the pressing signal of the hall button 34 is transmitted to the control device 60 as a reception signal. The control device 60 creates a notification signal corresponding to the press signal that is the received signal. The generated notification signal is transmitted to the notification section 46 of the car 40 using the notification signal line 96 as the remote communication signal line 90. The car-side maintenance worker 6 receives notification that the confirmation signal has been received from the pit-side maintenance worker 4, using the notification section 46 as a notification signal output device.

As described above, in the communication support system 70, the landing button 34 and the elevator status display section 36 of the car call panel 32 are used as the pit-side communication input/output device 50, and the destination floor is used as the car-side communication input/output device. An instruction panel 44 and a notification section 46 are used.

FIG. 5 is a detailed diagram of the portion V in FIG. 1, and is a diagram showing the configuration of the control device 60 and the connection relationship with each device used in the communication support system 70.

The control device 60 is connected to the storage section 62 through appropriate signal lines. The storage unit 62 is a storage device that stores various programs that are software executed by the control device 60, data in control processing, and the like. Here, a pit-out signal data string file 64 is stored that stores a data string of a predetermined pit-out signal for indicating a pit-out state.

The predetermined pit out signal is a data string in which a long press state in which the hall button 34 is pressed for a long time and a short press state in which the hall button 34 is pressed for a shorter time are arranged in a predetermined transmission order. The pit-out signal data string file 64 is a storage file regarding a data string of a predetermined pit-out signal.

An example of the pit-out signal data string file 64 is shown in FIG. Here, following an example of Morse code, a data string in which POUT is expressed in Morse code is shown. FIG. 6 is an example for explanation, and the signal data string should not be confused with the signal data string when the landing button 34 is unintentionally operated randomly by a third party other than the person concerned, such as a maintenance worker. Bye.

The control device 60 is a device that centrally controls the operation of each device of the high-rise elevator system 10. As the control device 60, a computer suitable for controlling the operation of an elevator is used. FIG. 5 shows various devices connected to the control device 60, such as an illumination meter 28, a landing button 34, a lift status display section 36, and a destination floor indicator panel 44, which are devices common to the normal mode, maintenance mode, and remote communication mode. , a notification section 46, a maintenance mode button 56, and a remote contact mode button 58.

The control device 60 has a normal mode, a maintenance mode, and a remote contact mode as part of the maintenance mode as control modes. A normal mode control block 100 in the control device 60 comprehensively controls the operation of each device in the normal mode, and a mode switching control block 102 controls mode switching between normal mode, maintenance mode, and remote communication mode. . The remote contact mode control block 104 comprehensively controls the operation of each device in the remote contact mode.

The normal mode control block 100 includes a normal operation control section 110. In the high-rise elevator system 10, the normal operation control unit 110 uses the hoistway 12 to load passengers from the landings 30 on each floor onto the cars 40, and moves them up and down the hoistway 12 according to the requests of the users. , performs the necessary control to land the passenger at the desired landing 30 and disembark the passenger.

Mode switching control block 102 includes a maintenance mode switching section 112 and a communication mode switching section 114. The maintenance mode switching unit 112 switches between the normal mode and the maintenance mode in response to the operation of the maintenance mode button 56, and the contact mode switching unit 114 switches between the maintenance mode and the maintenance mode in response to the operation of the remote contact mode button 58. Switch to remote contact mode below.

The maintenance mode switching unit 112 switches the connection relationship between the normal operation control unit 110 and the pit-side communication input/output device 50 and the car-side communication input/output device 52 in response to the operation of the maintenance mode button 56. When the display surface of the maintenance mode button 56 is off, it is the normal mode, and the pit side communication input/output device 50 and the car side communication input/output device 52 are connected to the normal operation control section 110, and the landing button 34 is used as a car call button. The destination floor indication panel 44 functions as a destination floor indication button.

When the display surface of the maintenance mode button 56 is in an off state, pressing the maintenance mode button 56 once switches from the normal mode to the maintenance mode. In the maintenance mode, the pit-side communication input/output device 50 and the car-side communication input/output device 52 are disconnected from the normal operation control unit 110. It is not transmitted to the control unit 110 and becomes an invalid operation. Similarly, even if a passenger presses a button with the number "33" displayed on the destination floor indication panel 44 to specify "33rd floor" as the destination floor, the information is not transmitted to the normal operation control unit 110 and is invalid. It becomes an operation.

The communication mode switching unit 114 switches the connection relationship between the remote communication mode control block 104 and the pit side communication input/output device 50 and the car side communication input/output device 52 in accordance with the operation of the remote communication mode button 58.

When the display surface of the maintenance mode button 56 is lit and the remote communication mode button 58 is off, the mode is maintenance mode. In the maintenance mode, the pit-side communication input/output device 50 and the car-side communication input/output device 52 are not connected to the normal operation control section 110 and further not connected to the remote communication mode control block 104. The operations of the pit-side communication input/output device 50 and the car-side communication input/output device 52 are both invalidated.

When the display surface of the maintenance mode button 56 is lit and the remote communication mode button 58 is off, pressing the remote communication mode button 58 once switches to the remote communication mode under maintenance mode. . Under the maintenance mode, the pit side communication input/output device 50 and the car side communication input/output device 52 are separated from the normal operation control section 110. When switching to the remote communication mode in this state, the pit side communication input/output device 50 and the car side communication input/output device 52 are connected to the remote communication mode control block 104.

The remote contact mode control block 104 includes a pit-out confirmation section 120, a notification data output section 122, a confirmation signal notification section 124, and a received signal notification section 126.

The pit-out confirmation unit 120 receives a landing button signal by using the signal output from the landing button 34 when the pit-side maintenance worker 4 who has returned to the landing 30 on the lowest floor operates the landing button 34 as a landing button signal. . If the light-off signal regarding the in-pit illumination light 26 has not been received from the illumination meter 28, the subsequent processing is terminated. When the lights-off signal is received, the received hall button signal is referred to as a predetermined pit-out signal stored in the pit-out signal data string file 64 of the storage section 62. The reference result is output to the notification data output section 122.

The notification data output unit 122 receives the reference result from the pit-out confirmation unit 120, and ends the subsequent processing if the hall button signal does not match the predetermined pit-out signal. Even if the light-off signal is received from the illumination meter 28, it is determined that the pit-out state is not present, and the subsequent processing is terminated. If the hall button signal matches a predetermined pit-out signal, it is determined that the vehicle is in a pit-out state, and predetermined notification data is created. An example of predetermined notification data is voice output data that states, ``Work in the pit has finished and you have returned to the landing on the first floor.It is safe to lower the car toward the first floor.'' be. This is an example for illustrative purposes, and any content may be sufficient as long as it indicates that the user is in a pit-out state. The created notification data is transmitted via the communication mode switching section 114 and the remote communication signal line 90 to the notification section 46, which is an output device of the car side communication input/output device 52.

In the above, the notification unit 46 for emergency notification is used as the output device of the car-side communication input/output device 52. If the notification unit 46 is a speaker that outputs an electronic sound, the above audio output data may be used as the notification data. In the case where the notification unit 46 is a simple speaker that outputs the real voice of a caretaker or the like outside the car 40, a predetermined notification sound is sent to the car side maintenance worker 6 to notify that "a pit-out state has been reached." It can also be used as a sound. When the notification unit 46 is a display device such as a liquid crystal display, text output data is created as the notification data.

In the above, the notification unit 46 in the car 40 has been described, but if the environment is such that the car-side maintenance worker 6 can hear the sound output of a notification buzzer for the maintenance worker installed on the car, , a notification buzzer or the like on the car may be used as the notification section 46. In this case, the notification data is indicated by making an intermittent buzzer sound instead of the normal notification buzzer sound.

The confirmation signal notifying unit 124 receives the confirmation signal output by the car-side maintenance worker 6 who has received the notification data indicating that “it is in a pit-out state” by the output of the notifying unit 46, and notifies the pit-side maintenance worker 4. Perform the processing to do. The car-side maintenance worker 6 who has received the notification data uses the destination floor indication panel 44, which is an input device of the car-side communication input/output device 52, to perform the "pit out" operation that has been agreed in advance with the pit-side maintenance worker 4. Input a confirmation signal to notify that the status has been confirmed. The confirmation signal notification section 124 receives the confirmation signal via the communication mode switching section 114 via the remote communication signal line 90, and creates predetermined notification data based on the received confirmation signal. The created notification data is transmitted via the communication mode switching section 114 and the remote communication signal line 80 to the elevation status display section 36, which is an output device of the pit side communication input/output device 50.

An example of the confirmation signal is to press a button on the destination floor indicator 44 with the number "40" indicating that the destination floor is the 40th floor. An example of the notification data is display data that causes the number display section 37 of the elevation status display section 36 to blink "40". This is an example for explanation, and the confirmation data to be input to the destination floor indication panel 44 and the notification data display to be output to the elevator status display section 36 are shared between the pit-side maintenance worker 4 and the car-side maintenance worker 6. It is sufficient to set the content in advance as the processing content of the confirmation signal notification unit 124.

The reception signal notification unit 126 receives the reception signal output by the pit-side maintenance worker 4 who has received the notification data indicating that “it has been confirmed that the car is in the pit out state” based on the output of the elevator status display unit 36, and Processing to notify the side maintenance worker 6 is performed. The pit-side maintenance worker 4 who has received the notification data uses the landing button 34, which is an input device of the pit-side communication input/output device 50, to perform the "Receive Notification Data" process agreed with the pit-side maintenance worker 4 in advance. Input the received signal that informs you that the As the received signal, a press signal output when the hall button 34 is pressed is used. The received signal notification section 126 receives a press signal, which is a received signal, via the remote communication signal line 80 and the communication mode switching section 114, and creates predetermined notification data based on the received signal. The created notification data is transmitted to the notification section 46, which is an output device of the car-side communication input/output device 52, via the communication mode switching section 114 and the remote communication signal line 90.

As described above, the remote communication mode control block 104 not only communicates that the pit-side maintenance worker 4 is in the pit-out state, but also communicates between the pit-side maintenance worker 4 and the car-side maintenance worker 6. We will contact you twice in between. The reason why the car 40 is lowered toward the landing 30 on the 1st floor only after multiple communication confirmations is because the pit 16 and the car 40 on the 40th floor are far apart This is to prevent misunderstandings caused by involvement of a third party in connection with the notification that the information is available.

The pit-out confirmation unit 120 refers to the push signal of the landing button 34 of the landing 30 on the first floor as a predetermined pit-out signal. There is a possibility of operating the button 34. Even in that case, the confirmation signal notifying unit 124 transmits a confirmation signal based on the confirmation signal input operation on the destination floor indication panel 44 in the car 40, which is difficult for third parties to enter, unlike the first floor landing 30. It is displayed on the elevation status display section 36 of the landing 30. Even if a third party is present at the landing 30 on the first floor, it is difficult to understand the contents of the notification displayed on the elevator status display section 36. It is also difficult to input a press signal. In this way, it is possible to prevent a third party from getting involved in communication between the pit-side maintenance worker 4 and the car-side maintenance worker 6, who are located far away from each other, and when the car 40 is descending, the pit-side maintenance worker 4 and the car-side maintenance worker 6 can The safety of the side maintenance worker 4 can be ensured, and maintenance work in the pit 16 will not be hindered.

7 and 8 are flowcharts showing the procedure of a communication support method applied to the communication support system 70 in the high-rise elevator system 10 configured as described above. As a procedure of the communication support method, the processing procedure of the pit-side maintenance worker 4 or the car-side maintenance worker 6 and the processing procedure of the control device 60 are integrated. Here, procedures that are mainly processed by the pit-side maintenance worker 4 or car-side maintenance worker 6 are surrounded by a broken line frame, and procedures that are mainly processed by the control device 60 are shown by a solid line frame.

In performing the communication support method in the high-rise elevator system 10, the control mode of the high-rise elevator system 10 is switched (S10). Here, the control mode of the high-rise elevator system 10 is switched from normal mode to maintenance mode, and further switched to remote communication mode under maintenance mode. Specifically, as shown in FIG. 4, inside the car 40, open the maintenance work panel 54, press the maintenance mode button 56, confirm that the display screen lights up, and then press the remote communication mode button 58. Press. When the display surface of the remote communication mode button 58 lights up, the mode switching process in S10 ends.

Next, the pit-side maintenance worker 4 is placed in the pit 16, and the car-side maintenance worker 6 is placed in the car 40 (S12). The processing order of S10 and S12 may be reversed to process S12 first and then process S10.

Then, the car 40 is moved to the landing 30 on the 40th floor, which corresponds to the top floor of the hoistway 12, and is stopped there (S14). As a result, the pit-side maintenance worker 4 and the car-side maintenance worker 6 are placed far apart, making it difficult for them to communicate with each other.

Then, the pit-side maintenance worker 4 performs maintenance work in the pit 16 (S16). The procedure for the pit-side maintenance worker 4 to enter the pit 16 from the landing 30 on the first floor, the procedure for turning on the pit lighting 26, the inspection of the amount of elongation of the main rope 22 as maintenance work, etc. are described in FIG. Therefore, the details will be omitted. When the maintenance work in the pit 16 is completed, the pit-side maintenance worker 4 returns to the landing 30 on the first floor. The procedure for turning on the in-pit illumination light 26, the operation of the illumination meter 28, the procedure for returning from the pit 16 to the landing 30 on the first floor, etc. have been described with reference to FIG. 2, so the details will be omitted.

The above is the procedure in FIG. 7, and the procedure in FIG. 8 is subsequently performed. When the pit-side maintenance worker 4 returns to the landing 30 on the first floor, the control device 60 determines whether or not a light-off signal from the illumination meter 28 is detected (S20). If the determination is negative, the procedure of S20 is repeated until the determination is positive.

In parallel with S20, the pit-side maintenance worker 4 presses the landing button 34 of the landing 30 on the first floor according to a predetermined procedure to transmit a landing button signal. The press operation for the hall button signal is performed in a predetermined transmission order of a long press state in which the press time is long and a short press state in which the press time is shorter than the long press state (S22).

The control device 60 determines whether the hall button signal transmitted from the hall button 34 is a predetermined pit out signal (S24). The example of the predetermined pit-out signal has been described in FIG. 6, so the details will be omitted. If the determination in S24 is negative, the subsequent processing ends. This is because even if a third party transmits push button signals in an appropriate transmission order, the subsequent steps will not proceed. Instead of terminating the subsequent processing, the display surface of the hall button 34 may be used to display that the push button signal does not match the predetermined pit out signal. For example, a display method such as repeated flashing on the display surface of the hall button 34 is used to notify the pit-side maintenance worker 4 that the push button signal is abnormal. The pit-side maintenance worker 4 who sees this returns to S22 and presses the landing button 34 of the landing 30 on the first floor again.

If the determination in S24 is affirmative, it is determined that the vehicle is in a pit-out state (S26), and the process proceeds to the next step. The processing procedure from S20 to S26 is executed by the function of the pit-out confirmation unit 120 of the remote communication mode control block 104 of the control device 60.

When it is determined that the pit-out state is present, predetermined notification data is created, and the created notification data is sent to the car-side communication input/output device 52 via the communication mode switching unit 114 and the remote communication signal line 90. The information is output to the notification unit 46, which is an output device (S28). This processing procedure is executed by the function of the notification data output unit 122 of the remote contact mode control block 104 of the control device 60.

Next, the car-side maintenance worker 6 who has confirmed the notification data operates the destination floor indication panel 44 of the car-side communication input/output device 52 to output a confirmation signal, and upon receiving the confirmation signal, the pit-side maintenance worker 6 The person 4 is notified (S30). This processing procedure is executed by the function of the confirmation signal notification section 124 of the remote contact mode control block 104 of the control device 60. The confirmation signal notification unit 124 creates appropriate notification data based on the received confirmation signal, and sends the created notification data to the pit side communication input/output device via the communication mode switching unit 114 and the remote communication signal line 80. It outputs to the elevation status display unit 36, which is the output device 50.

Next, the pit-side maintenance worker 4 who has received the notification data regarding the confirmation signal operates the landing button 34 of the pit-side communication input/output device 50 to output a received signal. The operator 6 is notified (S32). As the received signal, a press signal of the hall button 34 is used. This processing procedure is executed by the function of the received signal notification section 126 of the remote contact mode control block 104 of the control device 60. The received signal notification section 126 creates appropriate notification data based on the received reception signal, and sends the created notification data to the car side communication input/output device via the communication mode switching section 114 and the remote communication signal line 90. The signal is output to the notification section 46, which is the output device 52.

Then, the car-side maintenance worker 6 who has received the notification of the received signal issues a car lowering instruction under the maintenance mode, so upon receiving the car lowering instruction, the car 40 is lowered toward the lowest floor. Car descending control is performed (S34). When the user arrives at the landing 30 on the first floor, which is the lowest floor (S36), the user operates the maintenance mode button 56 to return the maintenance mode to the normal mode.

Until the car lowering instruction is issued in the maintenance mode and the car 40 lands on the landing 30 on the first floor, it remains in the remote communication mode, so it is possible to receive communication from the pit-side maintenance worker 4. Therefore, the pit-side maintenance worker 4 who has received the notification data regarding the confirmation signal allows the car 40 to continue descending for as long as he continues to press the landing button 34, and if he wishes to interrupt the descent of the car 40 for some reason. , the pressing of the hall button 34 can be interrupted. When the reason for the interruption disappears, by pressing the landing button 34 again, the car-side maintenance worker 6 issues an instruction to lower the car again.

Instead of the above, the car-side maintenance worker 6 who has been notified of the received signal switches the maintenance mode to the normal mode, sets the destination floor to "1" on the destination floor indicator board 44, and moves the car 40 to the first floor. You may go directly to the landing 30.

According to the elevator pit-out communication support system 70 configured as described above and the elevator pit-out communication support method used therein, a pit-out state is established between the inside of the pit 16 and the car 40 located on a floor remote from the pit 16. can be contacted without misunderstanding. Communication between the pit 16 and the car 40 on a remote floor is particularly effective in the high-rise elevator system 10, where it is difficult to visually check whether the in-pit illumination light 26 is on or off or to communicate by radio. In addition, since the remote communication mode control block 104 is provided in the control device 60 and the operation effect of the equipment already included in the high-rise elevator system 10 is changed and used, no special equipment is required.
