Description

  The present invention relates to an elevator including a broadcasting system.

  Conventionally, confirmation of the running state of the car, the current position of the car, the stopped floor, etc. (hereinafter referred to as “the state of the car” as appropriate) relies on the display of a car indicator installed in the car.

  However, when the car is congested or for a visually impaired person, it is not easy to grasp the state of the car only by vision.

  Therefore, an elevator has been proposed in which each time a car passes through each floor, a sound generator installed at the hall emits one type of sound such as a buzzer sound at the hall (see, for example, Patent Document 1). .

JP 57-1178 A

  However, with the buzzer sound, the person at the landing can determine that the car is running, but the passengers in the car can determine the running state such as whether the car is rising or falling. Furthermore, it is not possible to determine which floor the car has stopped. For this reason, the provision of an elevator including a broadcasting system that complements a conventional broadcasting system is required.

  An object of the present invention is to provide an elevator including a broadcasting system that can inform passengers of the state of a car more easily.

An elevator provided with a broadcasting system according to the present invention,
Whether it is installed in the shaft so that it can be raised and lowered,
An elevating mechanism for elevating the car within the shaft;
Elevating control means for controlling the elevating mechanism and moving the car up and down;
A broadcasting system that is electrically connected to the lifting control means and outputs sound in the car;
In an elevator equipped with
The lifting control means detects the traveling direction of the car,
The broadcasting system outputs different floor transition sounds according to the traveling direction of the car detected by the lifting control means.

A car position detecting means for detecting the current floor of the car in the shaft,
It is desirable that the broadcasting system outputs a floor transition sound corresponding to the traveling direction based on the detection of the car floor transition by the car position detecting means.

  According to the elevator equipped with the broadcasting system of the present invention, it is possible to output different floor transition sounds depending on the traveling direction of the car. Therefore, when the car is congested or a visually handicapped person, it depends on vision. The traveling direction or stop of the car and the traveling direction of the car can be discriminated by hearing without hearing.

  Also, by outputting a floor transition sound each time the car moves between floors, passengers can determine or roughly determine the current approximate location of the car and how long it will take to reach the desired floor as a destination. Can be judged.

FIG. 1 is a schematic diagram of the overall configuration of an elevator (10) according to an embodiment of the present invention, and FIG. 2 is a control block diagram.
As shown in FIG. 1, the elevator (10) is configured such that a car (20) on which a passenger rides can be moved up and down in a shaft installed in a building.
All control of the elevator (10) is performed in a control panel (40) provided in a machine room provided on the top floor of the shaft, and a car-side control panel (50) provided in an upper part of the car (20). It is done by. The control panel (40) and the car-side control panel (50) are each configured by mounting a microcomputer, memory, chip, switch, etc. on the board, and the control panel (40) and the car-side control panel (50) are connected by wire. Execute various programs necessary for the operation of the elevator (10).

The operation of the car (20) is performed by registration means provided in the car (20) and at the landings on each floor.
The registration means on the car (20) side is an operation panel (22) for registering a floor desired by the passenger as a destination (hereinafter referred to as `` destination floor '') and opening / closing the door, and the car-side control panel (50) Is electrically connected.
The landing registration means is a landing device (48) provided at the landing, registers a landing call according to the direction of the destination floor, and transmits it to the control panel (40). The hall device (48) is generally composed of an operation button for designating the upper floor and an operation button for designating the lower floor.

  In an elevator in which a passenger registers a destination floor in advance at the landing, a plurality of operation buttons for selecting the destination floor are arranged on the landing device. The present invention can also be applied to such an elevator.

  In the car (20), in addition to the operation panel (22) described above, a car indicator (24) indicating the current floor of the car (20) and the traveling direction, a floor transition from the broadcast system (30) described later, A speaker (32) that outputs sound such as sound is provided. These are all electrically connected to the car-side control panel (50).

  The broadcasting system (30) is a device that outputs various sounds from the speaker (32) to the car (20), and includes a sound reproducing unit (34) in the car-side control panel (50), and the sound reproducing unit. Sounds such as various floor transition sounds, voices, and notification signals transmitted from (34) can be output from the speaker (32). The sound reproducing unit (34) stores sound data such as floor transition sound, voice, and notification signal, and the sound data is called out as necessary and sound output from the speaker (32).

  As a voice, as shown in a balloon in FIG. 13 to be described later, guide the driving direction and door closing "I will go up. The door will close.", Guide the arrival floor and door opening "5th floor. An audio language such as “The door opens” can be exemplified.

Also, as the floor transition sound that guides the direction of travel of the car (20) during the traveling of the car (20), it is composed of three or more sounds of rising tone when ascending, three or more sounds of descending tone when descending, etc. Can be exemplified. Of course, the floor transition sound is not limited to this, and music, speech language, chime sound, buzzer sound, bell sound, siren sound, and the like can also be adopted.
In addition, since the floor transition sound becomes a wide frequency band by combining a plurality of frequencies, passengers who cannot easily hear a specific frequency band can be heard. Examples of combinations of frequencies include overtones.

  Examples of the notification signal include a chime sound, a buzzer sound, a bell sound, and a siren sound.

  The above-mentioned sound etc. are illustrations and are not limited to these.

The car (20) travels by an elevating mechanism (44) composed of a motor (46), a brake, a sheave, a rope, a counterweight, and the like.
The elevating mechanism (44), specifically, the motor (46) is controlled by elevating control means (42) provided on the control panel (40).
The rotation of the motor (46) is output as an encoder signal. Based on the number of pulses of the encoder signal, the car position detection means (51) detects the car position based on a difference value from the reference position of the car (20) (for example, the height of the landing floor on the lowest floor), and The traveling speed is detected based on the amount of change per unit time, and the traveling of the car (20) by the lift control means (42) is controlled based on the detection signal.

  Then, the car position detecting means (51) detects the current floor of the car (20).

  Further, the car position detecting means (51) includes a function as a passage detecting means (52) (see FIG. 2) for judging the floor shift of the car (20), and the floor shift sound of the broadcasting system (30) is detected. Control the output timing.

  In the present invention, the floor transition of the car (20) means that when the car (20) passes between the floor and any floor vertically adjacent, the car (20) This means when the vehicle passes or reaches a predetermined position, for example, a stop position of each floor.

  Further, the car position detecting means (51) includes a function as floor display switching means (53) (see FIG. 2) for switching the display of the car indicator (24), and the floor by the broadcasting system (30). It also controls the output timing of the transition sound and the acoustic guidance on the arrival floor.

  The shaft can be provided with a landing-free zone in which no landing (12) is provided. The no landing zone can be set in advance in the car position detection means (51), and the floor where the car (20) currently detected by the car position detection means (51) is the no landing zone. Can be determined.

  The broadcasting system (30) of the present invention can determine the state of the car (20) by hearing by outputting a floor transition sound corresponding to the traveling direction when the car (20) has moved up the floor. It is what I did.

Hereinafter, specific embodiments will be described with reference to the drawings.
FIG. 3 is a schematic diagram of an elevator (10) having a plurality of halls (12) and (12), and FIG. 4 is a timing flowchart for outputting a floor transition sound.

  The present embodiment is an example in which a floor transition sound corresponding to the traveling direction is output from the speaker (32) every time a floor transition of the car (20) is detected. In the embodiment, the floor transition sound output timing adopts the passage detection means (52), and detects the floor transition of the car (20) when the car (20) passes between the floors. Yes. A passenger who has boarded the car (20) from the first floor operates the operation panel (22) and travels in the ascending car (20) with the fourth floor as the destination floor.

  When the destination floor (fourth floor) is input to the operation panel (22), the input is transmitted to the car-side control panel (50) and the control panel (40). The elevator control means (42) selects the destination floor (4 in this example) from the current floor (the first floor), which is the departure floor, as the floor to which the car (20) should respond and stop. The traveling direction (rise) to the floor is detected, the motor (46) is rotated, and the car (20) is caused to travel (step 101).

  Until the car (20) arrives at the deceleration start position corresponding to the destination floor, the motor (46) continues to run at a high speed with a high rotational speed (No in Step 102, 103). ), It is detected that the car (20) has passed between the floors (Yes in Step 104), and the car-side control panel (50) uses the sound reproducing unit (34) to generate acoustic data corresponding to the traveling direction. Is output from the speaker (32) as a floor transition sound (step 105). The floor transition sound can be exemplified by a tone of up tone when the traveling direction is up, and a tone of down tone when the running direction is down.

Thereby, the passenger can discriminate visually whether the car (20) is traveling or stopped based on the floor transition sound without looking at the car indicator (24). Also, by changing the tone of the floor transition sound between rising and falling, the passenger can also determine the traveling direction by hearing from the floor transition sound without looking at the car indicator (24). . In particular, since the elevator (10) in recent years has a quiet running sound, it is difficult to determine whether it is running or stopped, but this problem is solved by the present invention.
In addition, passengers can determine how many floors the car (20) is currently driving by counting the number of times the floor transition sound has been heard from the departure floor, and how long it will take to reach the desired destination floor. You can determine if it will arrive.

  The above flow is repeated each time the vehicle passes between the floors until the deceleration start position corresponding to the destination floor is reached, and when the car (20) reaches the deceleration start position corresponding to the destination floor (Yes in step 102), the elevator moves up and down. The control means (42) reduces the speed of the motor (46) and decelerates the car (20) (step 106).

  If the car (20) has started decelerating in front of multiple floors on the destination floor, the car (20) will pass between one or more floors before reaching the destination floor (Yes in step 107). To do. When the passage detection means (52) detects the passage between the floors (No in Step 107, Yes in Step 108), the floor transition sound corresponding to the traveling direction is output again (Step 109).

  When the car (20) arrives at the destination floor (Yes in Step 107), the lift control means (42) stops the rotation of the motor (46), stops the car (20), and this timing flow ends.

  As the car (20) decelerates, the time interval between floors detected by the passage detection means (52) also becomes longer, so the interval at which floor transition sound is output also becomes gradually longer. Thus, the passenger can recognize by hearing that the car (20) is decelerating and is approaching the destination floor, so that the passenger can get off smoothly.

  While the car (20) is traveling, the landing device (48) is operated to generate a new landing call, or a new passenger operates the operation panel (22) to add a destination floor. Even when the car (20) travels and stops in response to the above operation, the floor transition sound may be output every time it passes between the floors according to the timing flowchart.

Further, as shown in FIG. 3, in the elevator (10) that changes the display of the car indicator (24) in conjunction with passing between floors, the floor transition sound output timing is set to the floor display switching means. May be synchronized with (53)
(Refer to steps 104 ′ and 108 ′ of FIG. 5 in the timing flowchart). In the present specification and drawings, the same step numbers in the timing flowcharts indicate the same processes.

  For example, when the floor display switching means (53) is adopted as the floor transition sound output timing, the current position of the car (20) is detected based on the encoder signal of the motor (46) as described above. Then, the floor display of the car indicator (24) may be switched, and in synchronization with this, control may be performed so as to output a floor transition sound corresponding to the traveling direction.

FIG. 6 and the timing flowchart FIG. 7 are obtained by adding a function for broadcasting the destination floor to the embodiment. As shown in a balloon display in FIG. 6, after arriving at the fourth floor which is the destination floor, “Ping Pong, the fourth floor” is broadcast in a speech language. This arrival guidance to the destination floor is executed in step 110 after arrival at the destination floor (Yes in step 107).
In addition to the floor transition sound, by audible broadcasting of the destination floor that has arrived, it is possible to judge by hearing whether the floor should be alighted or not without viewing the car indicator (24).

  When the floor display switching means (53) switches from the floor before the destination floor of the car (20) to the destination floor, it outputs a floor transition sound from the speaker (32) and then arrives at the destination floor. When the audio broadcast is performed, the floor transition sound and the audio broadcast of the arrival at the destination floor may be covered or continuously broadcast, making it difficult to hear. Therefore, in the above case, it is desirable not to output the floor transition sound (steps 104 ″ and step 108 ″).

  In the elevator (10) provided with the no landing zone, the floor transition sound output timing can be arranged as shown in FIGS. 8 to 11 while passing through the no landing zone. The output timing of the floor transition sound while passing through the no landing zone is executed based on either the passage detection means (52) or the floor display switching means (53).

  FIG. 8 shows an embodiment in which a floor transition sound is output when passing through the intermediate point of the no landing zone, in the illustrated embodiment, between the first floor and the fifth floor while passing through the no landing zone. It is. In this example, the car indicator (24) does not display the floor of the floor where there is no landing. A floor display switching means (53) is used for the floor transition sound output timing while passing through the no landing zone.

  FIG. 9 shows that even when passing through the no landing zone, the floor has been moved at the same timing as the floor transition timing of the stoppable floor (the timing of passing through the broken line position in the no landing zone in FIG. 9). This is an example in which a floor transition sound is sometimes output. Also in this example, the car indicator (24) does not display the floor of the floor where there is no landing. Passage detection means (52) is used for the floor transition sound output timing while passing through the no landing zone.

  FIG. 10 shows an embodiment in which the car indicator (24) is displayed not as a floor display but as a hyphen during passage through the no landing zone. As in FIG. 8, the floor display switching means (53) is adopted for the output timing of the floor transition sound while passing through the no landing zone. In the illustrated embodiment, the output timing of the floor transition sound is before and after the transition to the no landing zone, that is, when the transition from the first floor to the no landing zone and when the transition from the no landing zone to the fifth floor occurs.

  FIG. 11 is also an example in which the car indicator (24) is displayed as a hyphen instead of a floor display while passing through the no landing zone. As in FIG. 9, the passage detection means (52) is adopted for the floor transition sound output timing during the passage through the no landing zone. Note that the timing to output the floor transition sound while passing through the no landing zone by the passage detection means (52) need not be limited to the same timing as the floor transition timing of the stoppable floor, and the floor transition sound is output. Any other timing may be used as long as it passes through a predetermined car position.

FIG. 12 is a timing chart of the output of the floor transition sound for the embodiment of FIGS.
When the destination floor is input to the operation panel (22), the elevation control means (42) detects the direction of the destination floor, rotates the motor (46), and raises the car (20) (step 201). .

  High speed running is continued until the vehicle arrives at the deceleration start position corresponding to the destination floor (No in step 202, 203). When the floor display switching means (53) as shown in Fig. 8 or 10 is adopted for the floor transition sound output timing while passing through the no landing zone, only when the floor display of the car indicator (24) is switched. The floor transition sound can be output (Yes in step 204). Thereafter, a floor transition sound corresponding to the traveling direction is output until it is determined that the floor display of the car indicator (24) matches the destination floor and the destination floor is reached (No in step 205, step 207). .

  When the passage detection means (52) as shown in FIG. 9 or FIG. 11 is adopted for the floor transition sound output timing while passing through the no landing zone, the floor is at the same timing as the floor transition timing of the stoppable floor. When the transition is made, the floor transition sound can be output (Yes in step 206). Thereafter, a floor transition sound corresponding to the traveling direction is output until it is determined that the floor display of the car indicator (24) matches the destination floor and the destination floor is reached (step 207).

  Thereby, the passenger can distinguish the traveling direction of the car (20) by hearing.

  When the deceleration start position corresponding to the destination floor is reached (Yes in Step 202), the elevation control means (42) reduces the rotational speed of the motor (46) and decelerates the car (20) (Step 208).

When deceleration is started from a plurality of floors before the destination floor, the vehicle passes through one or more floors before reaching the destination floor (No in step 209). When the car position detecting means (51) detects this passage, the output of the floor transition sound is controlled (step 210 to step 213) in the same manner as in steps 204 to 207.
When arriving at the destination floor (step 209), an audio broadcast to the effect that it has arrived at the destination floor is performed (step 214), and the lift control means (42) stops the rotation of the motor (46) and stops the car (20). This timing flow ends.

  In addition, when there is a new landing call or addition of a destination floor, the car (20) may be run and stopped in response to these calls.

  While passing through the no landing zone as described above, floor transition sound can be output by adopting either the floor display switching means (53) or the passage detection means (52). FIG. 12 shows both a case where the floor display switching means (53) is adopted and a case where the passage detection means (52) are adopted in one flowchart, but in actuality, either one is adopted. It is processed.

  Similarly, when traveling outside the no landing zone, it is possible to output floor transition sound by adopting either the floor display switching means (53) or the passage detection means (52).

  Since the output interval of the floor transition sound output from the speaker (32) can be changed, the passenger can also identify by hearing whether the car (20) is traveling inside or outside the no landing zone. is there.

  As shown in FIG. 13, the car position detection means (51) outputs when the car (20) detects that the car (20) has shifted to the first floor in the vertical direction. The floor transition sound to be generated can be attracted to the passengers by making it louder than the subsequent floor transition sounds. For example, it is desirable to increase the first floor transition sound by about 5 dB compared to the subsequent floor transition sound.

  If all floor transition sounds are made louder, passengers may feel noise when the noise in the car (20) is small. There is an advantage that the passenger can recognize that it is output and can easily recognize that the traveling state of the car (20) can be determined by the floor transition sound.

  Also, as shown in FIG. 14, when the car (20) has a high boarding rate, the noise increases due to the congestion in the car (20), so the floor transition sound can be changed according to the boarding rate. Is desirable. Specifically, not only the floor transition sound output first but also the subsequent floor transition sound is increased. The boarding rate can be determined by, for example, the weight of the car (20), the number of registered destination floors, image recognition, and the like.

  For elevators (10) where the car (20) moves up and down fast, every time it passes through multiple floors without outputting a floor transition sound every time it passes between floors, for example, 3-5 floors The output timing may be changed so that a floor transition sound is output for each transition.

  Furthermore, the lifting speed of the car (20) is divided into, for example, a low speed range below a predetermined speed and a high speed range exceeding it, and the output timing of the floor transition sound is changed between the low speed range and the high speed range, compared to the low speed range. Thus, the output timing in the high speed range may be delayed. If the output timing in the low speed range is changed to the high speed range, the output interval becomes too short and the floor transition sounds overlap each other, making it difficult to hear. However, by delaying the output timing in the high speed region as compared with the output timing in the low speed region as described above, it is possible to prevent the sound of floor transition sounds from overlapping in the high speed region.

  Add the car (20) ascending / descending speed to the low speed and high speed areas, and divide the car (20) into the ultra low speed area where the ascending / descending speed of the car (20) is slower than the low speed area. By delaying the output timing in the area, it is possible to prevent the floor transition sound from being extended in the ultra-low speed area.

  In addition to changing the output timing, the output timing is changed in the ultra low speed range, low speed range, and high speed range by changing the tone of the floor transition sound, for example, the pitch and length of the sound. Is not only recognized, but also has the advantage of being able to grasp the lifting speed of the car (20) by hearing.

In addition, as shown in FIG. 2, passenger judging means (56) for judging the presence or absence of passengers in the car (20) is connected to the control panel (40) or the car-side control panel (50). By avoiding the broadcasting of floor-to-floor sounds and other sounds, it is possible to save power and to avoid unnecessary sounds from being generated in the building.
Passenger determination means (56) can be the operation panel (22), it can be determined that there is no passenger because the destination floor registration operation is not performed on the operation panel (22) in the car (20). it can. Moreover, a camera, an infrared sensor, etc. may be arrange | positioned in a cage | basket | car (20), and the presence or absence of a passenger may be determined. It can also be determined by the weight of the car (20), image recognition, and the like.

Of course, the tone color of the floor transition sound described above is not limited to the above, but it is desirable to select a sound that is not mistaken for an alarm sound.
It is also desirable to select a sound that can be sensed ascending or descending.

  According to the elevator equipped with the broadcasting system of the present invention, since the car is traveling, the traveling direction of the car, and the position (number of floors) of the car can be confirmed by hearing, the passenger can check the operation status of the car. Can judge without relying on vision. In addition, the passenger can predict how long it will arrive from the information to the desired destination floor, and can determine that the floor where the car has stopped is the desired destination floor.

  The temporary output stoppage of the floor transition sound may be stopped by operating the operation panel (22) (for example, pressing the door open button and the door close button at the same time, Press the door close button to stop the output). In this case, the output of the floor transition sound is stopped after the output stop operation, but the release of the output stop can be appropriately set after the end of one run or when there is no passenger. Further, the floor transition sound may be temporarily stopped by setting a time zone (for example, stopping output at night).
