In the first embodiment, the notification information indicating the recognition sign sound and the response sign sound is information configured to include identification information for specifying the recognition sign sound and the response sign sound, respectively.

The recognition sign sound signal storage unit 111 stores the sound signal of the recognition sign sound indicated by the notification information received by the notification information receiving unit 101. Specifically, it is composed of a memory that stores sound signals of a plurality of recognition sign sounds that may be specified by notification information, for example, encoded sound data.

The response sign sound signal storage unit 121 stores the sound signal of the response sign sound indicated by the notification information received by the notification information receiving unit 101, and may be specifically specified by the notification information. It is composed of a memory for storing sound signals of a plurality of response sign sounds, for example, encoded sound data.

The guidance sign sound signal storage unit 201 stores the sound signal of the guidance sign sound, and is composed of a memory for storing the sound signal of the guidance sign sound, for example, encoded sound data.

The recognition sign sound signal storage unit 111 and the response sign sound signal storage unit 121 may be configured by one memory, or the recognition sign sound and the response sign sound sound signals may be shared. It should be noted that the sound signals of the recognition sign sound and the response sign sound have an appropriate length of time to be used for exchanging sounds.

The detection unit 131 is a microphone 151 that collects the sound of the elevator landing, a landing sound storage unit 161 that stores the sound collected by the microphone 151 as the sound data of the landing sound, and a landing sound stored in the landing sound storage unit 161. A sign sound recognition unit 171 that recognizes a recognition sign sound from the inside is provided. The sign sound recognition unit 171 refers to the sound signal of the recognition sign sound specified by the notification information among the sound signals stored in the recognition sign sound signal storage unit 111, and stores the landing sound stored in the landing sound storage unit 161. By analyzing it, the recognition sign sound in the landing sound is recognized. When the recognition sign sound in the landing sound is recognized, the sign sound recognition unit 171 outputs a detection signal indicating that the recognition sign sound has been recognized.

The response sign sound output unit 141 includes a speaker drive unit 181 and a speaker 191. The speaker drive unit 181 receives a detection signal from the detection unit 131, and then receives a response sign during the period when the detection unit 131 does not output the detection signal. The speaker 191 is controlled to output the response sign sound specified by the notification information among the sound signals stored in the sound signal storage unit 121. The speaker drive unit 181 controls the speaker 191 so as to output the guide sign sound stored by the guide sign sound signal storage unit 201 when the squealing is not performed.

Each part having the same name as the passenger guidance device 91 has the same function.

Next, the operation of the elevator system configured in this way will be described.

In this elevator system, after assigning an appropriate unit to the user who operated the landing operation device 1 and performed the car calling operation, the passenger guidance of the landing operation device 1 is performed in order to guide the user to the assigned unit. The device 91 and the passenger guidance device 92 of the unit notification device 2 squeal and exchange.

FIG. 3 is a flow chart showing the operation of the central control device 4 in this elevator system.

When the elevator system starts operation, the central control device 4 monitors in step S1 that the calling means 8 of the landing operation device 1 is operated.

When the calling means 8 is operated, the process proceeds to step S2, and the operating means 5 determines an appropriate unit for the user who has operated the calling means 8. There may be various ways to determine the appropriate unit. For example, if there is a machine that is preferentially used by users with specific attributes such as people with disabilities and the elderly, a machine that matches the user's attributes determined from the user image acquired by a camera etc. may be assigned. There are ways to decide, such as assigning a unit that will operate more efficiently as a whole elevator system, based on the user's destination floor and movement direction designation and the position and direction of each elevator.

When the assigned machine is determined in step S2, the process proceeds to step S3, and the operating means 5 controls to move the assigned machine to the floor where the user who called the car is located.
At the same time, the operation means 5 transmits the information of the assigned unit to the notification information transmitting means 6, and the notification information transmitting means 6 generates the notification information to be sent to the assigned unit and the landing operation device 1. This notification information includes identification information for specifying the recognition sign sound and the response sign sound in the assigned unit and the landing operation device 1 as described above. In the notification information transmitting means 6, first, a pair of two sounds to be squealed is determined, and the identification information indicating the determined sound is used as the identification information of the recognition sign sound and the response sign sound, and the passenger guidance device 91 of the landing operation device 1 is used. The notification information to be sent to is generated, and the notification information in which the identification numbers of the recognition sign sound and the response sign sound are exchanged is generated as the notification information to be sent to the passenger guidance device 92 of the assigned unit. As a result, the identification information of the response sign sound sent to the passenger guidance device 91 becomes the same as the identification information of the recognition sign sound sent to the passenger guidance device 92, and the identification information of the response sign sound sent to the passenger guidance device 92 is the identification information of the passenger sign sound. It becomes the same as the identification information of the recognition sign sound sent to the guidance device 91.
Then, the notification information generated in this way is transmitted to the landing operation device 1 and the unit notification device 2 of the assigned unit.

When such notification information is received by the passenger guidance devices 91 and 92 of the landing operation device 1 and the unit notification device 2 of the assigned unit, respectively, the passenger guidance devices 91 and 92 perform a squealing operation as described later. It will be.

As the operation of the central control device 4, the process returns to step S1 and monitors whether or not the new calling means 8 is operated.

In step S1, if there is no operation to the calling means 8, the process proceeds to step S4, it is confirmed whether or not the assigned machine moved in step S3 has arrived at the floor where the user is, and if not, step S1 Return to. By such a loop of step S1 and step S4, the operation to the new calling means 8 and the monitoring of the arrival / absence of the assigned unit are repeated, and during this time, the notification information is transmitted from the notification information transmitting means 6 in step S3. The passenger guidance devices 91 and 92 of the landing operation device 1 and the unit notification device 2 of the assigned unit perform the squealing operation to guide the user to the position of the assigned unit.

The squealing by the passenger guidance devices 91 and 92 may be terminated when all of the assigned units moved in step S3 arrive at the floor where the user is. Therefore, in the central control device 4, when it is determined in step S4 that the assigned unit has arrived at the floor where the user is, the process proceeds to step S5, and an operation for ending the squealing by the passenger guidance devices 91 and 92 is performed. Specifically, in step S5, new notification information for stopping the output of the sign sound of the passenger guidance device 92 of the assigned unit is transmitted from the notification information transmitting means 6 to the landing operation device 1 and the unit notification device 2. In the notification information for stopping the output of the sign sound, the response sign sound and the recognition sign sound for the passenger guidance device 92 of the assigned unit are not specified. That is, the identification information that identifies the recognition sign sound and the response sign sound included in the notification information is information indicating that each is "none", and the passenger guidance device 92 of the assigned unit that receives this is the information. Stops the output of the response sign sound. As a result, the squealing operation by the passenger guidance devices 91 and 92 is completed.

If a plurality of units are singing and only some of them arrive, the identification information for identifying the recognition sign sound and the response sign sound only for the passenger guidance device 92 of the arriving unit is ". Send notification information for information indicated to be "none". Notification information of a new recognition sign sound and response sign sound is transmitted to the passenger guidance device 91 and the passenger guidance device 92 of the unit that has not yet arrived, and the squealing continues.

After that, the process returns to step S1, and if there is an operation for the new calling means 8, the same operation as described above is performed, and the assigned machine assigned to the car call is used for exchanging sounds.

Subsequently, when the notification information is transmitted from the notification information transmission means 6 to the passenger guidance devices 91 and 92 of the landing operation device 1 and the unit notification device 2 of the assigned unit in step S3, the passenger guidance devices 91 and 92 are used. The squealing operation will be described. FIG. 4 is a flow chart showing the operation of the passenger guidance device 91, and FIG. 5 is a flow chart showing the operation of the passenger guidance device 92. The passenger guidance devices 91 and 92 operate according to these flow charts to interact with each other and exchange sounds. conduct.

First, in the passenger guidance device 91 of the landing operation device 1, the speaker drive unit 181 drives the speaker 192 so as to output the guidance sign sound stored in the guidance sign sound signal storage unit 201 in step S6 when the operation of the elevator system starts. do. From this guidance sign sound, the user can grasp the location of the landing operation device 1.

After that, in step S7, the notification information receiving unit 101 monitors whether the notification information is received, and if the notification information is not received, the steps S6 and S7 are repeated, and the repeat guidance sign for notifying the location of the landing operation device 1 is repeated. Continue to output sound.

When the notification information is received in step S7, the process proceeds to step S8, the output of the guidance sign sound is stopped, the process proceeds to step S9, and the subsequent processing for exchanging sounds by the passenger guidance device 91 is performed.
First, in step S9, the identification information indicating the recognition sign sound included in the notification information received by the notification information receiving unit 101 is stored in the recognition sign sound signal storage unit 111, and the identification information indicating the response sign sound is stored in the response sign sound signal storage. It is stored in the unit 121.
By receiving this notification information, the two sounds that the user who performed the calling operation should hear, that is, the sounds that are squealed between the landing operation device 1 and the assigned unit, can be known. By notifying the users in the vicinity of 1 of these sounds, it is easy to recognize which sound the user should rely on to go to the assigned machine. At that time, the information of the assigned machine for uniquely identifying the assigned machine, for example, the position and the name of the assigned machine may be notified, and the user may be notified of which unit has been assigned, whereby the user may be notified. The assigned machine can be surely recognized.

After step S9, in step S10, the speaker drive unit 181 reads out the sound signal specified by the identification information indicating the response sign sound stored in step S9 as the sound signal of the response sign sound from the response sign sound signal storage unit 121. The sound is output to the speaker 191. The output of this response sound becomes the first output sound of the squealing, and the squealing is performed thereafter.

The response sign sound is stored in the response sign sound signal storage unit 121 as having an appropriate length of time to be used for exchanging, and the response sign sound is stopped after being output for this time. The output time of the response sign sound may be changed regardless of the length of the sound signal stored in the response sign sound signal storage unit 121. For example, the response sign sound signal storage unit 121 may store a short sound pattern, and when outputting the response sign sound, this pattern may be repeated and output for an appropriate time.

Further, assuming that the sounds exchanged between the landing operation device 1 and the unit notification device 2, that is, the response sign sounds output by both of them are related sounds, even the user who hears the sign sound for the first time can intuitively pair the sign sounds. Easy to understand. This pair of sounds is, for example, a pair of sounds "pawn (bass)" and "pawn (treble)" with the same tone but different pitches, or a tone "pawn (440Hz)" with the same pitch but different pitches. And "popon (440Hz)" tones.

The output of the response sign sound in step S10 is the response sound to the unit notification device 2 which is the partner of the squeal. This response sound is collected together with the surrounding sounds by the microphone 152 of the passenger guidance device 92 of the unit notification device 2, and is recognized as the recognition sound in the passenger guidance device 92. When the response sign sound is output from the passenger guidance device 91 for an appropriate time and is interrupted, the passenger guidance device 92 that recognizes this is output the response sound, as will be described later.

After that, in step S11, a storage operation is started in which the landing sound storage unit 161 stores the sound collected by the microphone 151 that collects the sound of the elevator landing as the sound data of the landing sound. This memory operation is continuously performed.

Next, in step S12, the sign sound recognition unit 171 recognizes the sound signal specified by the identification information indicating the recognition sign sound stored in step S9 among the sound signals stored in the recognition sign sound signal storage unit 111. The recognition operation for recognizing the recognition sign sound in the landing sound is started by analyzing the landing sound stored in the landing sound storage unit 161 with reference to the sound signal of the sound. In the recognition operation in step S12, when the sign sound recognition unit 171 recognizes the recognition sign sound in the landing sound stored in the landing sound storage unit 161, "1" is used as a detection signal indicating that the recognition sign sound is recognized. If not recognized, "0" is output to the speaker drive unit 181 as a detection signal indicating that the recognition sign sound is not recognized.

The recognition operation of step S12 by the sign sound recognition unit 171 is sequentially performed, and the speaker drive unit 181 sequentially monitors the detection signal from the sign sound recognition unit 171 in step S13, and receives the detection signal "1". After that, it is confirmed whether the detection signal "0" has been received. In other words, the sign sound recognition unit 171 outputs a detection signal "1" indicating that the recognition sign sound has been recognized, and then outputs a detection signal "1" indicating that the recognition sign sound is desired to be recognized. It means that we are confirming that it is no longer in the state. By this confirmation operation, the sound output from the speaker 192 of the passenger guidance device 92 of the unit notification device 2 which is the other party, that is, the response sound of the passenger guidance device 92 and the recognition sound of the passenger guidance device 91 are in the landing sound. It can be confirmed that it disappeared after appearing in. This confirmation operation in step S13 is repeated after receiving the detection signal "1" until it is confirmed that the detection signal is no longer received, that is, until "YES" is obtained in step S13.

If "YES" is obtained in step S13, the process proceeds to step S14, and the speaker drive unit 181 uses the sound signal specified by the identification information indicating the response sign sound stored in step S9 as the sound signal of the response sign sound. It is read from the signal storage unit 121 and output to the speaker 191. As a result, the response sign sound is output during the period when the sound output from the speaker 192 of the passenger guidance device 92 of the unit notification device 2 which is the other party of the squealing appears in the landing sound and then disappears.

The passenger guidance device 91 outputs a response sign sound in step S14, and then determines in step S15 whether new notification information has been received between the reception of the notification information in step S7 and the step S14, and has not received it. In that case, the process returns to step S12, and the processing according to step S12 is performed again from step S12 to repeat the recognition of the sound output from the passenger guidance device 92 and the output of the response sound. By repeating steps S12 to S14, the squealing with the unit notification device 2 is repeated.

If it is determined in step S15 that new notification information has been received, the process proceeds to step S16. Receiving new notification information indicates that it is an instruction to change the unit notification device that performs the squealing or an instruction to end the squealing that is currently being performed.

When changing the unit notification device for exchanging sounds, the response sign sound and the recognition sign sound used with the unit notification device for newly exchanging sounds in step S3 of FIG. 3, which is the operation of the central control device 4. Is the case where the specified notification information is sent. When this notification information is received, it is determined in step S16 that both the recognition sign sound and the response sign sound are specified, and the process returns to step S9. Then, by the above-mentioned operation described above, the recognition sign sound and the response sign sound are updated, the new recognition sign sound is recognized, and the new response sign sound is output, so that a new squeal and a squeal with the other party are performed.

On the other hand, when the current squealing exchange is terminated, all the assigned units arrive at the destination floor, and in step S5 of FIG. 3, which is the operation of the central control device 4, "recognition" for terminating the squealing exchange is performed. / No response sign sound ”is sent. When this notification information is transmitted, it is not determined that both the recognition sign sound and the response sign sound are specified in step S16, that is, it is determined that it is NO, the process returns to step S6, and the response sign sound that has been output up to that point is output. Instead, it outputs a guidance sign sound and returns to the process of monitoring the next notification information.

Subsequently, the operation of the passenger guidance device 92 of the Unit 2 notification device 2 will be described with reference to FIG. The passenger guidance device 91 of the landing operation device 1 of FIG. 4 first outputs the guidance sign sound, but the passenger guidance device 92 of the unit notification device 2 does not need to output the guidance sign sound, and the central control device 4 does not need to output the guidance sign sound. All you have to do is wait for the instructions of the crying. First, in step S17, the notification information receiving unit 102 monitors whether or not the notification information has been received, and if the notification information is received, the process proceeds to step S18.

In step S18, the identification information indicating the recognition sign sound included in the notification information received by the notification information receiving unit 102 is stored in the recognition sign sound signal storage unit 112, and the identification information indicating the response sign sound is stored in the response sign sound signal storage unit. It is stored in 122. Here, as described above, the recognition sign sound and the response sign sound are specified in the notification information sent to the passenger guidance device 91 of the landing operation device 1 and the notification information sent to the passenger guidance device 92 of the unit notification device 2, respectively. The identification information has been replaced. That is, in the notification information sent to the passenger guidance device 91, when the identification information of the recognition sign sound indicates the sound of the sign sound A and the identification information of the response sign sound indicates the sound of the sign sound B, the notification information is sent to the passenger guidance device 92. In the notification information to be received, the identification information of the recognition sign sound indicates the sound of the sign sound B, and the identification information of the response sign sound indicates the sound of the sign sound A.

Therefore, in the passenger guidance device 91, when the recognition sign sound signal storage unit 111 stores the identification information of the sign sound A and the response sign sound signal storage unit 121 stores the identification information of the sign sound B in step S9, the passenger guidance device 91 guides the passenger. In the device 92, the identification information of the signature sound B is stored in the recognition sign sound signal storage unit 112 in step S18, and the identification information of the signature sound A is stored in the response sign sound signal storage unit 122.

Then, in step 22, the speaker drive unit 181 reads out the sound signal specified by the response sign sound A stored in step S18 from the response sign sound signal storage unit 121, and causes the speaker 192 to output the sound signal for a certain period of time.

Subsequent steps S19 to S24 are the same as steps S11 to S16 in FIG. 4, which is the operation of the passenger guidance device 91 of the landing operation device 1 described above.

In step S20, the passenger guidance device 92 starts the recognition process of the recognition sign sound B. When the passenger guidance device 91 outputs the first response sign sound B in step S10 of FIG. 4 for a certain period of time, the passenger guidance device 92 recognizes in step 21 that the response sign sound B is output and ends, and in step S22. The response sign sound A is output from the speaker 192 of the passenger guidance device 92. Such operations from step S20 to step S23 are repeated until the next notification information is received, and the sounds are exchanged. If it is determined in step S23 that the next notification information has been received, the process proceeds to step S24, and if both the recognition sign sound and the response sign sound are specified in the notification information, a new recognition sign sound and response sign are specified in step S18. If it cannot be said that both the recognition sign sound and the response sign sound are specified in the notification information, the process returns to step S17, and the response sign sound is not output any more. And wait for the next notification information.

FIG. 6 is a sequence diagram showing a state in which squealing is performed by the operation of the central control device 4, the landing operation device 1, and the unit notification device 2 as described above.

First, when the elevator system starts operation, the landing operation device 1 repeatedly outputs a guidance sign sound in step S6 until the user calls the car.

When the car is called, the central control device 4 determines an appropriate assigned unit for the user in step S2, moves the assigned unit in step S3, and makes a sound between the landing operation device 1 and the assigned unit notification device 2. Sends notification information indicating the recognition sign sound and the response sign sound. In the example of FIG. 6, the notification information sent to the landing operation device 1 is "recognition sign sound A, response sign sound is sign sound B", and the notification information sent to the unit notification device 2 is "recognition sign sound". Identification information such as "sign sound B and response sign sound is sign sound A" is included.

Upon receiving the notification information, the landing operation device 1 outputs the response sign sound B in step 10. When the unit notification device 2 recognizes the response sign sound B and detects the end of the response sign sound A in step S21, the unit notification device 2 outputs the response sign sound A in step S22.
Then, the landing operation device 1 recognizes the end of the response sign sound A in step S13, and the operation of outputting the response sign sound B in step S14 is repeated, and the sounds are exchanged.
When the assigned unit arrives during this squealing operation (YES in step S4), the notification information for the central control device 4 to stop the output of the sign sound of the passenger guidance device 92 of the assigned unit in step S5, that is, the recognition sign sound. , The notification information of "None" is transmitted to the landing operation device 1 and the unit notification device 2 together with the response sign sound. Upon receiving this notification information, the landing operation device 1 determines in step S16 that neither the recognition sign sound nor the response sign sound is specified, and returns to step S6 to output the guidance sign sound. Further, the unit notification device 2 that has received the notification information returns to step S17 by the same determination in step S24. This ends the squealing.

In the above description of FIG. 6, there was one unit notification device 2 that squeals with the landing operation device 1, but as shown in FIG. 2, since there are a plurality of unit notification devices 2, the unit that squeals and exchanges with each other. If another unit is called before the arrival of the unit, a plurality of units will squeal with the landing operation device 1. The state in which the plurality of units and the landing operation device 1 squeal will be described with reference to the sequence diagram of FIG. 7.

In the sequence shown in FIG. 7, first, the unit corresponding to the unit notification device 2a is called to become the assigned unit, and the squealing exchange with the landing operation device 1 is started, and then another unit notification device 2b is called. It became the assigned unit and started to squeal with the landing operation device 1, after that, the unit corresponding to the unit notification device 2a arrived and the squealing ended, and the unit corresponding to the unit notification device 2b also arrived. An example of the transition to end the squeal is shown.

First, the unit corresponding to the unit notification device 2a becomes the assigned unit, and the same operation as in FIG. 6 is performed until the unit notification device 2a outputs the sign sound A and the landing operation device 1 outputs the sign sound B and exchanges the sounds. It is done.
While the landing operation device 1 is exchanging with the unit notification device 2a, another user performs a car call operation, and the central control device 4 assigns the unit corresponding to the unit notification device 2b to the assigned unit. Then, the central control device 4 transmits the notification information to each of the landing operation device 1, the unit notification device 2a, and the unit notification device 2b in step S3.
At this time, the notification information sent to the landing operation device 1 is "recognition sign sound is sign sound C, response sign sound is sign sound B", and the notification information sent to the unit notification device 2a is "recognition sign sound is sign sound B," The notification information sent to the unit notification device 2b includes identification information such that "the response sign sound is the sign sound A" and "the recognition sign sound is the sign sound A and the response sign sound is the sign sound C".
When the landing operation device 1 receives the notification information, it starts outputting the sign sound B in step S10, the unit notification device 2a starts the recognition operation of the sign sound B when it receives the notification information, and the unit notification device 2b outputs the notification information. Upon receipt, the recognition operation of the sign sound A is started.
When the unit notification device 2a detects that it has stopped after recognizing the sign sound B output from the landing operation device 1 for a certain period of time in step S21, it outputs the response sign sound A in step S22. Further, when the unit notification device 2b detects in step S21 that it has stopped after recognizing the response sign sound A output from the unit notification device 2a for a certain period of time, it outputs the response sign sound C in step S22. Then, the landing operation device 1 recognizes this sign sound C, and outputs the response sign sound B again. Such a series of operations is repeated, and a response sound is output in the order of the landing operation device 1, the unit notification device 2a, the unit notification device 2b, the landing operation device 1, and so on.

When the unit corresponding to the unit notification device 2a arrives during this squealing operation (YES in step S4), the central control device 4 transmits notification information in step S5.
At this time, the notification information sent to the landing operation device 1 is "recognition sign sound is sign sound C, response sign sound is sign sound B", and the notification information sent to the unit notification device 2a is "no recognition sign sound, no response sign sound". The notification information sent to the unit notification device 2b includes identification information that "the recognition sign sound is the sign sound B and the response sign sound is the sign sound C".
When such notification information is transmitted, the unit notification device 2a does not output the response sign sound A, so that the sound exchange by the unit notification device 2a ends, and between the landing operation device 1 and the unit notification device 2b. The squealing exchange using the sine sound B and the sine sound C is continuously performed.

After that, when the unit corresponding to the unit notification device 2b arrives (YES in step S4), the central control device 4 transmits the notification information in step S5. Here, the notification information sent to the landing operation device 1 has identification information "no recognition sign sound, no response sign sound", and the notification information sent to the unit notification device 2b has "no recognition sign sound, no response sign sound". include. Then, the unit notification device 2b that has received the notification information stops outputting the sign sound C, and the landing operation device 1 returns to the state of outputting the guidance sign sound in step S6, so that the landing operation device 1 and the unit notification device 1 and the unit notification device are output. The exchange with 2b ends.

In the above embodiment, the recognition sign sound and the response sign sound are determined and notified to the landing operation device 1 and the unit notification device 2 each time the unit is assigned, but the landing operation device 1 and each unit are notified in advance. If different response sign sounds are assigned to the notification devices 2, it is not necessary to notify the response sign sound each time the unit is assigned. In that case, the notification information includes only the recognition sign sound identification information, and the unit notification device 2 that receives the notification information confirms the recognition and termination of the sign sound indicated by the recognition sign sound identification information included in the notification information. By doing so, a pre-assigned response sign sound is output. When there is one unit notification device 2 in which the landing operation device 1 squeals and exchanges, the recognition sign sound notified to the unit notification device 2 is the response sign sound of the landing operation device 1 and the recognition sign notified to the landing operation device 1. The sound becomes the response sign sound of the unit notification device 2. Further, when there are a plurality of unit notification devices 2 in which the landing operation device 1 squeals and exchanges, the recognition sign sound notified to each unit notification device 2 is in the order of outputting the response sign sound among the plurality of unit notification devices 2. The response sign sound assigned to the previous unit notification device 2 and the recognition sign sound notified to the unit notification device 2 are the response sign sound assigned to the last unit notification device 2 in the order of outputting the response sign sound.
