Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides airborne signals such as audio,
The present invention relates to an elevator control device that enables car management operations such as elevator call registration using remote command signals such as light, ultrasonic waves, and radio waves.

Conventionally, an elevator is operated by a passenger registering a call by pressing a destination floor button provided inside the car or a landing button provided at a landing. However, when the car is crowded, it may be difficult to press the destination floor button, and in particular, when a physically handicapped person uses the elevator, it may be impossible to press the destination floor button. Therefore, it has been considered to install a voice recognition device in the elevator or in the hall, and to register a call using the passenger's voice.

Voice recognition devices such as those described above can sometimes be disturbed by other passengers' voices or noises, for example, or if the passenger's voice is too low.
Passenger voices may not be recognized correctly. As a result, the registration of the call is delayed, and by the time the call is registered, the car has already passed the desired floor of the passenger in the car or the floor where there are passengers waiting for the landing, which seriously impairs passenger service. It will make things worse.

Therefore, this invention disables car management operations such as call registration using remote command signals, except in cases where a recognition device for remote command signals such as voice, light, and ultrasonic waves is required, such as when driving exclusively for physically disabled persons. Further, it is an object of the present invention to provide an elevator control device which stops call registration using a remote command signal in a situation where the recognition device cannot recognize the remote command signal, and enables early call registration by manual operation of a button or the like.

The following invention will be described with reference to embodiments shown in the drawings. The figure shows an example of application to a control device for a five-story building that uses voice as a remote command signal and enables call registration. 6 is a microphone installed in the elevator car. , 7 is a voice recognition device, and this voice recognition device 7 identifies the content of the voice signal 6a converted into an electric signal by the microphone 6, and outputs the destination floor recognition signals 1C to 5C corresponding to the destination floor. When the audio signal 6a cannot be identified, or there is no floor that can be identified, or a floor where the car is not serviced. Unrecognized signal 6 when
C is output as an "H" pulse signal (about 0.5 seconds). Above destination floor recognition signal 1
C to 5C are individually applied as one input to AND gates 11 to 15, and each output of the AND gates 11 to 15 is input to one input of OR gates 16 to 20, respectively. In addition, the above OR gate 16
20 are set and applied to separate memory devices (flip-flops) 21 to 25, and when these memory devices 21 to 25 are set, the car call registration signals 1D to 5 on the 1st to 5th floors are output. 5
D is sent, and 1 to 25 are sent to the memory elements 21 to 25.
The fifth floor car signals 1A to 5A are introduced as reset inputs. In addition, the above AND
Gates 11-15 constitute a first command circuit, and OR gates 16-20 and memory elements 21-
25 constitutes a control circuit for registering and canceling car calls.

1B to 5B are button signals generated by pushing the destination floor buttons for the 1st to 5th floors provided in the car (when the button is pressed, an "H" signal is sent), and each button signal 1B to 5B is each separate AND gate 26~
30 as one input, and the outputs of the AND gates 26-30 are added as the other inputs of the OR gates 16-20, and the outputs of the AND gates 26-30 are added as the other inputs of the OR gates 16-20, as in the case of audio. When the output becomes "H", the car call registration signals 1D to 5D for the 1st to 5th floors are sent out from the memory elements 21 to 25. Note that the AND gates 26 to 30 constitute a second command circuit.

Reference numeral 10 designates a switching circuit for disabling the output of either one of the first command circuit comprising the AND gates 11 to 15 and the second command circuit comprising the AND gates 26 to 30. A pulse counter 31 that counts the number of occurrences of the unrecognizable signal 6C from the recognition device 7, and a count value Y of this pulse counter 31 and a constant value signal 32.
A comparator 33 compares the value X (= twice) and sets the output to "H" when X>Y, and the output of this comparator 33 is used as one input, ”
AND with dedicated operation signal 8 as the other input
The output of the AND gate 34 is applied as the audio valid signal 10a to the other input of the AND gates 11 to 15 in the first command circuit, while the output terminal of the AND gate 34 is connected to the NOT gate 35. When the output of the AND gate 34 becomes "L" and the output of the NOT gate 35 becomes "H", it is connected to the other input terminal of the AND gates 26 to 30 in the second command circuit. As a button enable signal 10b, that is, a signal that enables car call registration using the destination floor button.
It is designed to be input to AND gates 26-30. Further, a notification device 36 operated by the output from the NOT gate 35 is provided,
This notification device 36 synthesizes a voice indicating that "the car call button is valid and the voice call registration is invalid" periodically for a certain period when the input signal is "H", and its output is installed inside the car. The message is supplied to the loudspeaker 37, which is driven to inform the passengers in the car of the above-mentioned gist.

Note that 9 is a running signal for resetting the pulse counter 31 of the switching circuit 10, which is "H" from the time when the car starts running until it stops;
When the car is stopped, it is "L".

Next, the operation of the inventive device configured as described above will be explained.

Assume now that the car is on the first floor facing upwards, that the car is set to be operated exclusively for the handicapped, and that the door is open. In this state, the car position signal 1A is "H", the others are "L", the running signal 9 is "L", the dedicated operation signal 8 is "H", and the memory element 21 is "L".
The memory contents of 25 to 25 are reset and their outputs are all "L". Since the contents of the pulse counter 31 controlled by the running signal 9 are reset to zero when the car stops, the comparator 3
The output of No. 3 is "H" because of the relationship X (=2)>Y (=0). Therefore, AND gate 3
The output of 4 becomes "H", and the AND of the 1st command circuit
A voice valid signal 10a is given to the gates 11 to 15 so that call registration by voice is possible. On the other hand, when the AND gate 34 becomes "H"
The output of the NOT gate 35 becomes "L", and the AND gates 26 to 30 of the second command circuit are disabled for call registration by button.

If a passenger who has boarded the car on the first floor announces to the microphone 6 that the car is on the third floor, the voice is picked up by the microphone 6 and input to the voice recognition device 7 as a voice signal 6a. The voice recognition device 7 identifies the third floor of the destination from the voice signal 6a, and the destination floor recognition signal 3C becomes "H". As a result, the two inputs of the AND gate 13 become "H", so the output of the AND gate 13 becomes "H", and the output of the OR gate 18 also becomes "H".
Then, the stored contents of the memory element 23 are set to "H", and the car call registration signal 3D is sent out to register the car call for the third floor. At this time, the unrecognized signal 6C remains at "L", so the contents of the pulse counter 31 do not change. If the passenger presses the destination floor button on the third floor without using the voice, the button signal 3B will become "H", but the button valid signal 10b from the NOT gate 35 will change due to the voice valid signal 10a = "H". Because it is marked "L", the car call on the third floor cannot be registered using the button.

When a passenger calls the third floor into the microphone 6, if the voice recognition device 7 is unable to recognize the destination floor due to surrounding noise, etc., the unrecognized signal 6C is a pulse signal of "H" (0.5 seconds). This pulse signal is counted by a pulse counter 31. As a result, pulse counter 3
1 sends out an output of 0+1=1, but since the content is smaller than the constant value X, the output of the comparator 33 maintains "H".

If the voice recognition device 7 is unable to recognize the passenger's destination floor, which is the third floor, the unrecognized signal 6C becomes "H" again, and the pulse counter 31 counts as 1+1=2. Since the value of the constant value signal 32 becomes equal to the value of the constant value signal 32, the comparator 3
The output of 3 becomes "L". As a result, the output of the AND gate 34, that is, the voice valid signal 10a becomes "L" and invalidates the voice call registration, and at the same time, the NOT gate 35 is inverted and the button valid signal 10b becomes "H", thereby Notification device 36
Then, the speaker 37 is operated to broadcast to the passengers in the car, "Voice registration is invalid. Please press the destination floor." This broadcast is repeated periodically (every 3 seconds). Also, during this broadcast period, the content of the pulse counter 31 is reset to 0 and the output of the comparator 33 is set to "H" so that the car starts running and the running signal 8 becomes "H". Audio valid signal 10a=“H”, button valid signal 10b=
This continues until it reaches "L".

When the passenger presses the destination floor button on the 3rd floor due to the above broadcast, button signal 3B becomes "H", and the above
AND receiving output “H” from NOT gate 35
The output of gate 28 becomes "H", and OR gate 1
Since the output of 8 also becomes "H", the memory element 23 is set and the car call registration signal 3D is set to "H".
so that car calls for the third floor can be registered.

In other words, if voice-based car call registration is enabled and the destination floor cannot be accurately identified by voice for a predetermined number of times, voice-based call registration is disabled and button-based call registration is enabled. Allow passengers to reach their destination floor.

In addition, when the elevator is not operated exclusively,
Since dedicated operation signal 8 is held at “L”, AND
Output of gate 34, i.e. audio valid signal 10a
is always set to "L", and it becomes impossible to register a car call by voice. Instead of this, NOT Gate 3
The output of 5 is always "H" and the button valid signal 10b
, the AND gates 26 to 30 of the second command circuit respond to the button signals 1B to 5B, making it possible to register a car call using the buttons.

Note that this invention is not limited to limited operation for persons with disabilities, etc., but also during normal elevator operation.If voice call registration is enabled, if the destination floor cannot be recognized by voice for a predetermined number of times, voice call registration will be performed. Call registration may be disabled. This can prevent the car from being too preoccupied with voice call registration and having a hard time leaving the car, or from starting to run and passing the destination floor button. In addition, the voice method of the present invention is useful not only for car call registration, but also for canceling unnecessary floor calls, registering and canceling landing calls, door opening and closing operations, and landing calls during operations such as VIP operation. It may be used as an operation command such as passing through (in place of a pass button), canceling car calls all at once, or calling a car back to a predetermined floor. When operating an elevator using a button, it can be done by voice, and the voice of a specific person can be stored so that various operation commands can be given using only that person's voice.

Furthermore, the notification device is not limited to one that synthesizes voices, and may, for example, use a recording tape to make the necessary announcements, and it is of course possible to use a visual display method such as text.
Furthermore, in the above embodiment, even if the number of times the voice recognition device fails to recognize the command exceeds a predetermined number of times and the voice command becomes invalid, it is re-enabled every time the car goes to another floor. When a predetermined number of floors or more occur, the function may be completely disabled until an operator operates the function. In this way, it is possible to prevent passengers from feeling distrustful of voice recognition operations due to failure of recognition occurring here and there, and from causing inconvenience to passengers due to delays in operations such as call registration. Furthermore, the car name registration is not limited to the name of the destination floor, but may also be registered with a name corresponding to the destination floor, such as a company name, a store name, a restaurant name, etc.

In addition, this invention method is not limited to call registration within the car, but also includes a voice recognition device 7 and a microphone 6 installed at the elevator landing, so that waiting passengers can receive the name of the destination floor or an equivalent name, or the direction in which they are going. or by pressing the landing button.
It is also possible to register or cancel a hall call. In addition, although there is no display normally, there are display devices at landings that display waiting time information only when a passenger gives a command, as well as in the manager's room where staff are located, and in the machine room where elevator drive devices are installed. It can also be used as a command to a guide display device, etc.

In contrast to giving operation commands such as registering and canceling car calls by directly touching a button, etc., when you give operation commands in a non-contact manner using voice etc. as a medium, so-called remote commands, the remote command signal is teeth,
In addition to using only audio as in the above embodiments, light, ultrasonic waves, oscillation signals, etc. may also be used.

As described above, according to the present invention, when car management operations such as car call registration using voice or other remote command signals become uncertain, this is detected and the switch is activated.
I switched to management commands using buttons, etc., so
This system eliminates the delay in registering calls and the reduction in elevator operating efficiency that occurred in the past, and improves passenger service.
