Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an automatic elevator broadcasting device for broadcasting necessary information to elevator passengers and the like.

[Background of the invention]

While the elevator is in operation, an automatic broadcasting device (
For example, a device like the one described in Japanese Utility Model Application Publication No. 59-9872
) is used. The broadcasts made by these automatic broadcasting devices had to be made in appropriate synchronization with the movement of the elevator, but none of the conventional automatic broadcasting devices satisfactorily met this requirement. In addition, in order to activate the automatic broadcasting device, there are some that use a passenger proximity sensor that responds to passenger movements as described in Japanese Patent Application Laid-open No. 56-7878, but such a sensor is not able to detect it at the site of use. The drawback was that accuracy control was extremely difficult.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned conventional problems and provide an automatic elevator announcement system that can make announcements to passengers and the like at appropriate timing.

[Summary of the invention]

In order to achieve the above object, the present invention provides an elevator equipped with an automatic broadcast mechanism having a voice data memory, a voice synthesis section, a loudspeaker, and a control section for controlling these.
A signal detected by a signal detector related to the drive of the elevator door is input to the control device, and the control device outputs a signal for controlling the operation of the automatic broadcasting device at an appropriate timing. .

[Embodiments of the invention]

．． Speech synthesis unit 5 that synthesizes an audio signal based on audio data
．． and a loudspeaker 6 that converts audio signals into audio.

The control unit 3 receives an announcement content selection signal 63S, a caution announcement end command signal 82S, and a caution announcement start command No. 1 91S, and when the signal 82s is input, the warning announcement is stopped and the signal 913 is input. Then, signal 638 initiates the selected caution announcement.

Caution announcements include 281 announcements such as a door opening warning announcement, such as "The door is opening," and a door closing warning announcement, such as "Please be careful of the closing door." Signal 63s is a high level signal. When the door is opened, a warning announcement is made, but the signal is low level.

K is set so that an announcement will be made to warn when the door is closed. That is, the control section 3 determines whether the signal 63s is at a high level or a low level, outputs an address signal in response to this, and retrieves the audio data stored at the address from the audio data memory 4.

This audio data is input to the audio synthesis section 5, which outputs the °C audio signal and controls the loudspeaker 6 to issue a warning announcement.

Announcement content selection signal 63S, caution announcement end command signal 82S, and caution announcement start command signal 91
The circuit configuration for outputting s is as follows. That is, 102 is a door close detector that detects a close signal among the door drive signals output from the elevator system m (not shown), and 12 is a door close detector that also detects an open signal. Reference numeral 13 denotes a light-on detector which is outputted from the elevator control device prior to the door opening operation. Here, the car call response light +x is an indicator light that lights up when a passenger or the like presses 111 inside the elevator, and turns off before the car arrives and the door opens. 21, 23 are leading edge differentiating circuits that output pulses according to the rising edge of the input signal; 22,

This is a timer which outputs a signal for a predetermined period of time in response to the input of the output signal 52S of the cable 52, and a 7-rig flop circuit which is reset by the signal 51S and set by the signal 52sK. The output of this flip 7og circuit becomes the aforementioned announcement content selection signal 63s. 71°7

This is a trailing edge differential circuit that outputs a pulse at the falling edge of 62 seconds. 81 and 82 are OB sweets, and the output of the OR+ element 82 is the above-mentioned caution anakunsu end command signal 82S.
becomes. 91 inputs the output signal 81s of the OR element 81;

This is a delay circuit that outputs a signal after a predetermined time has elapsed, and the output of this delay circuit 91 becomes the aforementioned caution announcement start command signal 91s.

Next, the operation of this embodiment will be explained. Here, switch 3
6 is assumed to be closed (the operation when the switch is open will be described later).

First, when the car is stopped on the first floor, for example, and is waiting with the door closed, when a passenger presses the first floor hall button (not shown), the elevator control device described above opens the door in response. Outputs a signal to activate the door drive device,
The door drive starts opening the door. On the other hand, by outputting the door open signal.

Door open detector 12 tX detects this signal and outputs a high level signal. This high level signal changes one input terminal of the AND element 52 to a high level via the zero element 31 and the differential circuit 41. By the way, since the switch 36 is closed, the input to the inverter is at a low level and its output is at a high level. Therefore, the other input terminal of the AND element 52 also becomes high level through the OR element, and the AND element 5
The signal 52g from 2 is at a high level.

When the output signal 52s of the AND element 52 becomes high level, (1) the tree flop circuit 63 is set and its output signal 63S becomes a bulk level, and the automatic broadcaster 411
The control unit 3 of No. 2 retrieves data for issuing a warning announcement when the door is opened from the audio data memory 4. (2) Also, the output signal 823 of the OR element 82 becomes high level, and the control unit 3 interrupts the warning announcement if it is made by the automatic broadcasting mechanism 2 (in such a case, L (described later) 3) An output signal 62S is generated from the timer 62, and its rising edge causes the differentiating circuit 72 and OR element 81 to
The delay circuit 91 starts its operation via. Soshi [1.
A signal 913 is output after a predetermined time has elapsed. The control unit 3 starts the caution announcement by inputting the signal 91s. (
4) The output signal 62S of the timer b2 is also input to the trailing edge differentiator circuit 4, and the output signal 623 is output after the set time of the timer 62.
When becomes a low level, its fall causes an output and O
A signal 82s is output from the R element 82, and the caution announcement is ended.

The above operations can be summarized as follows. That is.

When the output of the door open signal is detected, the signal 82S is immediately output, and if a caution announcement is being made, this is interrupted. Thereafter, the signal 91s is output after a delay time by the delay circuit 91K, and the door opening warning announcement selected by the signal 63s is executed. When this announcement is completed and the time set in the timer 62 has elapsed, the anax operation is stopped. Since these operations are started at the same time as the output of the door open signal is detected, the door open warning announcement is made at an appropriate timing, either shortly before the door actually starts to open, or at the same time as the door actually begins to open.

Accidents when opening the door can be prevented.

When the door opening is completed, the door open signal disappears, and the output signal of the door close detector 12 becomes low level. Due to its fall, the trailing edge differentiator circuit n outputs the signal 223, which supports the reset of the free lag flop circuit. state and prepare for the next operation.

Enter each signal functionally based on the description above.

Signal 12 s is a signal during door opening operation, signal 22 s 4
The signal 52 is a signal indicating the completion of the door opening operation, and the signal 62& is a signal for preparing a warning announcement when the door is opened.

Next, after a predetermined period of time has elapsed after the first passenger presses the button for the destination floor after the door has been opened, or when the passenger presses the door close button after pressing the button for the destination floor, the elevator control device Then a door close signal is output. The door close detector 11 detects this door close signal and outputs a high level signal. The leading edge differentiating circuit 21 outputs a high level signal in response to the rise of this high level signal. On the other hand, as mentioned above, the output signal of the inverter north is at a high level, so the zero element 4
The output signal 42s of No. 2 also becomes high level. Therefore, it is a work.

The output signal 51s of the AND element 51 becomes a high-level signal, (1) the 7-lip 70-tub circuit 63 is reset and its output signal 63s becomes a low-level signal, and the control section 3 of the automatic broadcasting system 2 outputs the audio data memory. Data for making a warning announcement when closing the door is extracted from 4. (2) Also, OR
The output signal 82s of the g-child 82 becomes high level, and if a caution announcement is made, this is interrupted (1) (such a case will be described later). (3) The timer 61 outputs a signal 61S.

Upon the rising edge of the signal, the delay circuit starts operating via the differentiating circuit 71, 0 and 81, and after a predetermined time elapses, the signal 91g
is output, and the control unit 3 starts issuing a caution announcement. (4) The output signal 61s of the timer 61 is also input to the trailing edge differentiation circuit 74, and the set time of the timer 61! When the lkK output signal 61s becomes low level, its fall produces an output, causing the element 82 to output the signal 82S and ending the caution announcement.

The above operations can be summarized as follows. Rule.

When the output of the door close signal is detected, a signal 823 is immediately output, and if a caution announcement is being made, this is interrupted. Thereafter, a signal 91s is output after a delay time by the delay circuit 91, and the door opening caution announcement selected from the signal 633K is executed. When this announcement is completed and the time set in the timer 62 has elapsed, the announcement operation is stopped. Since these operations are started at the same time as the output of the door close signal is detected, the door close warning announcement is made at an appropriate timing, either shortly before the door actually starts to close or almost at the same time. Accidents when closing the door can be prevented.

From the above explanation, the signal 21S is a signal to start closing the door, and the signal 51s is a preparation signal for a warning announcement when closing the door.

It can be seen that the signal 61s has the function of a signal for permitting a warning announcement when the door is closed, and the signal 81S 42 has the function of a start signal for the warning announcement when the door is opened or closed.

Next, after the doors are closed, the elevator car moves toward the desired floor specified by the push button.

When approaching the target floor, a deceleration signal is output that causes the elevator control device to decelerate the movement of one elevator. The deceleration detector 13 detects this deceleration signal and outputs a high level signal. The leading edge differentiating circuit 23 outputs a high level signal due to the rise of this high level signal, and therefore, O
R, sweets The output signal S also becomes high level. Therefore, the flip-flop circuit A is set, and its output signal S also becomes high level, and both input terminals of the AND element 520 become high level through the zero switch 31 and the leading edge differentiator circuit 41. After that, the same operation as the door opening operation described above is performed, and a door opening caution announcement is made at an appropriate timing, either shortly before the door actually starts to open, or at the same time as the door opening warning announcement. Prevent accidents.

Note that during the above operation, after the deceleration detector 13 outputs a signal, the elevator is stopped and the door is opened.

The door open signal is output and the output of the door closed detector 12 becomes high level, but since the output of the flip frog 32) is already at high level, the high level output of the door closed detector 12 becomes invalid and the door is not opened again. Prevents caution announcements from being made.

On the other hand, when a passenger presses a push button for a certain floor to turn on the call response light, the same operation as described above occurs when the elevator decelerates to a stop.

In other words, when the elevator runs and stops at a certain floor,
The call response light goes out before the door opens. The lighting detector of the corresponding floor among the lighting detectors 141 to 14n outputs a high level signal due to this turning off, sets the output signal 333 of the OB+ element to high level, and sets the 71J tube flop circuit blade. The same operation will occur thereafter. From the above explanation, it can be seen that the signal 338% 323 has the function of a door opening advance signal.

Next, a case will be described in which a door that is once closed is reopened for some reason. When the door is closed, when the automatic announcement mechanism 2 is making a warning announcement when the door is opened by the above operation, when a door open signal is output from the elevator control device.

The output of the door closed detector 12 becomes high level, and the
1. The output signal 52s of the CAND element 52 is set to high level through the leading edge differentiating circuit 41. As a result, the output signal 52s of the CAND element 52 is set to high level.
The output signal 823 also becomes high level, and the control unit 3 immediately ends (interrupts) the door closing warning announcement being broadcast by inputting this high level signal 82g. Thereafter, a door opening caution announcement is made by the same operation as the door opening operation described above. During this time, a signal 61s is output from the timer 61, but this does not affect the door opening operation in any way. In addition, contrary to the above, if the door that was once opened is closed for some reason,
The currently broadcast door opening warning announcement will be interrupted, and the door closing warning announcement will be broadcast instead.

Since the operation is similar to the above operation, the explanation will be omitted.

The above description of the operation of this embodiment was for the case where the switch was closed, but the following is a description of the operation.

The operating pressure when the switch is open will be explained. When switch A is opened, inverter A's output signal 383 goes to a low level. First, in the elevator control device, when a door open signal is output, the output of the door close detector 12 becomes high level, and one input terminal of the ANJ) element 52 is output via the OR element 31 and the leading edge differential circuit 41. is also at a high level. By the way, at this point, the output of the door close detector 11 is of course at a low level, so the timer 61 is activated.
The output signal 61S of is also at a low level. This output signal 61
Since S is inverted and input to the OR element 43, the OR
The output signal 43 s kl of the element 43 is at a high level, and the other end of the AND element 52 is also at a high level. Therefore, the output signal 52s of the AND element 52 also becomes high level, and thereafter, the door opening caution announcement is executed by the same operation as the door opening operation described above. It is clear that even when the door is closed, the door closing warning announcement is executed in accordance with the above operation.

Next, a case will be described in which a door that is once closed is reopened for some reason. When the door is closed.

When the automatic broadcasting mechanism 2 is making a door close warning announcement through the above operation, when a door open signal is output from the elevator control device, the output of the door close detector I2 becomes a high level, and the OR element 31° One input terminal of the AND element is set to a high level through the leading edge differentiating circuit 41. By the way, at this point in time, the door closing warning announcement is being made, so the output signal 61sGs of the timer 61 is at a high level, and this signal 61s is inverted and input to the OR element 43. . In addition, since the output of the inverter is at a low level with the switch open, the output signal 43 s k' of the element 43 is eventually ORed.
! The signal becomes a low level, and the other end of the AND element 52 becomes a low level. Therefore, the output signal 52 S of the AND element 52
becomes a low level, the warning announcement end command signal 82s is not output from the zero element 82, and the door closing warning announcement is broadcast to the end without being interrupted. timer 61
becomes low Y bell after the set time elapses, automatic broadcast mechanism 2
is stopped, and at the same time the output signal 43s of the 08 element 43.

That is, the input signal at the other end of the AND element 52 becomes high level. However, at this time, since the input signal at one end of the AND element 52 is at a low level, the output signal 52g of the AND element 52 is at a low level, and the door opening caution announcement is not made. In other words, even if a door that is about to close is opened again, the door closing warning announcement will continue to the end without being interrupted, eliminating the discomfort felt by passengers due to the sudden change in broadcast content. I can do it. Note that the operation when the door that is about to open is closed for some reason is also similar to the above operation, so a description thereof will be omitted. From the above explanation, the switch 36 is a function that selects either to interrupt the once-broadcast caution announcement and change the contents of the engineering announcement when the door is reversed, or to continue the once-broadcast announcement to the end. It turns out that it has.

42.1 in 2 to 5 examples. Since the automatic announcement mechanism is activated in response to the opening and closing of the door, it is possible to issue a door open warning annunciation and a door warning annunciation at the perfect timing, thereby preventing accidents when opening and closing the door. I can do it. Also, since warning broadcasts are made using signals from a detector installed in the first car, the signals from the control panel are taken out. There is no need to add a tail cord or cord, improving work efficiency.

Furthermore, when the switch A is closed, it is possible to perform a warning alarm matching the opening and closing operations of the door, making it easier for one passenger to respond. Furthermore,
If the warning announcement is set to be made earlier than the door operation, the noise generated when the door opens and closes can be reduced. Also, since the broadcast interval is set not to be within a predetermined time, noise can be reduced. or,
Since it is equipped with multiple auxiliary detectors when the door is opened, it can be used in many types of elevators, and can be applied to various purposes in field work.

In addition, in the description of the above-mentioned embodiment, the content of the announcement was explained as a warning announcement when opening/closing a door, but the present invention is not limited to this, and can be applied to various kinds of announcements. Also, although we have explained the case where there are two types of announcement contents, if these can be made into one type (in the above example, 1, for example, 1ai of "Please be careful of the door")
), a circuit configuration for outputting an announcement content selection signal is not required. Furthermore, in the explanation of the above embodiment, the number of announcements is made only once per command, and the number of announcements is kept to a minimum to reduce noise, but the number of announcements is not limited to this, and the announcement is repeated multiple times. You can do it like this. or.

The automatic broadcasting mechanism starts and ends broadcasting using a start command signal and an end command signal, respectively.However, broadcasting can be started by directly inputting an announcement permission signal (the output signal of the timer in the above example) to automatic broadcasting am. It is also possible to end the broadcast.

Furthermore, when the door is opened upon reaching the destination floor, it is possible to do this prior to the door opening.

As mentioned above, in this embodiment, the operation of the automatic announcement mechanism is controlled according to the signal related to the door drive.
, so announcements to each passenger etc. can be made at appropriate timing.
