Description

Description: TECHNICAL FIELD The present invention relates to an elevator announcement device that automatically announces messages to elevator passengers according to the operating status of the elevator.

[Conventional technology]

An elevator announcement device is convenient as a man / machine interface between an elevator user and an elevator, and is installed in many elevators. As is well known, the contents of the announcement are, for example, "door closed announcement" and "full capacity announcement" in a normal use state. Also, when there is a power failure or failure, it is an "emergency call button operation request announcement".

These announcements give optimum announcements each time according to the driving situation of the elevator, as if a dedicated driver was on board. As a conventional technique of this type, for example, as disclosed in Japanese Patent Laid-Open No. 63-262692, a warning command is given from the elevator side, and according to this command, voice data corresponding to the command is taken out and announced. To do.

In addition, the announcement at the time of power failure / failure is output from the elevator side by the normally closed contact in consideration of the alarm at the time of power failure, and the contact is open except at the time of power failure / failure. That is,
When there is a power failure, the elevator side loses power, so the normally-closed contact that was open closes, and according to this, the necessary announcement is made at the time of a power failure.

[Problems to be Solved by the Invention]

Since the conventional elevator announcement device is configured as described above, it achieves its purpose in the event of an actual power failure, but if the power on the elevator side is cut off for some reason, it will be in the same state as a power failure, The announcement device falsely reports an emergency announcement for power outage.

Therefore, if an emergency announcement is made when unnecessary, elevator passengers will feel unnecessary anxiety, and since an announcement is made each time the power is cut off, there are drawbacks such as noise.

The present invention has been made to solve the above problems, and can prevent unnecessary emergency announcements for power outages even when the power of the elevator is cut off, and forget to cancel the emergency announcement prevention means when the power is restored. It is an object of the present invention to obtain an elevator announcement device that can make an announcement necessary for elevator operation.

[Means for solving the problem]

According to the present invention, an announcement unit that automatically announces a message to elevator passengers according to various operating conditions, such as stop operation and normal operation during elevator power failure.
When the validity of the message notification is recognized during the invalidation of the message notification, and an announcement invalidating means for setting the notification of the message to the announcement unit to be invalid or valid,
The announcement unit is provided with a compulsory announcement command means for giving a message issuing command.

[Action]

In the elevator announcement device according to the present invention, the announcement invalidation means sets the notification of the message to invalid when the elevator power supply needs to be shut off, thereby making the message for elevator power supply stop / fault unnecessary from the announcement part. It will not be automatically issued.

Furthermore, by setting the forced announcement command means,
Even if you forget to switch the announcement invalidation means to the valid side, by operating the announcement part after the elevator power is restored,
A message required for elevator operation can be automatically announced.

〔Example〕

The invention will be described with reference to the drawings. FIG. 1 is a block diagram of an elevator announcement device according to the present embodiment. In the figure, (1) is an elevator control panel that creates an announcement notification command in accordance with the operating status of the elevator. (2) shows an elevator announcement device, which is composed of the following blocks.
(3) shows a forced announcement command means, and the forced announcement command is supplied from the elevator control panel (1).
(4) is a central announcement unit, which takes out corresponding voice data in accordance with various announcement commands issued from the elevator control panel (1), converts it into voice, and outputs it to the speaker (9). (5) is an announcement invalidating means, which outputs an announcement invalidation command to the announcement unit (5). (6) is a power failure detection. When the power supply of the elevator announcement device is cut off, the power failure is detected and the emergency power supply (8) is supplied to the power supply section (7).

FIG. 2 shows a detailed configuration of a microcomputer (hereinafter, microcomputer) of the announcement unit (2). (+) Is the DC power supply for controlling the announcement device, (11) is the CPU, (12)
Is a ROM that stores the announcement notification control program and voice data. (13) is RAM, (1
4) indicates an input device. (16), (17) and (19) are warning request signals supplied from the elevator control panel.
(16) is a normally closed contact that issues an announcement "Press the emergency call button," which is an announcement for power failure / failure, and (17) Always issues an announcement, "Door is closed," which is a door closed announcement. Open contact, (19) is a forced announcement command. If the power of the elevator control panel is normal, it will be closed. If the power is cut off, the forced announcement command will be normally open contact. (18) will be an elevator announcement device. This is a normally open contact of the announcement invalidation command switch that invalidates the announcement command from the elevator side that is installed and closed. (15) is an output device, which issues an announcement through the speaker (9).

FIG. 3 shows the operation of the microcomputer section of the announcement section (4) shown in FIG. Since the operation of the elevator during normal operation and when an actual power failure or failure occurs is well known, description thereof will be omitted. Now, an embodiment of the present invention will be described with reference to the operation when the elevator is actually stopped.

Elevator control panel (1) to stop the elevator
And the announcement device (2) for the elevator is turned off. In process 20, the announcement invalidating means (18) is
Since it is not ON, the process proceeds to step 21. In process 21, since the elevator control panel power is shut off, the announcement command (16) for power failure or failure is closed, and the process proceeds to process 24. In this process, an erroneous alarm "emergency call button" is issued. Please press. ”Make an announcement.

However, the use of the announcement invalidation command means (5) which is a feature of the present invention can prevent the above false alarm. Then
This operation is invented. Before shutting off the power to the elevator control panel and the announcement device for the elevator, turn on the announcement disable switch (18) of the announcement device for the elevator,
After that, the power of the above device is cut off. In process 20, since the announcement invalidating means (18) is turned on, the process proceeds to process 22.
In process 22, because the elevator control power supply is cut off, the announcement compulsory command means (19) is open, and the process proceeds to process 26, the announcement is invalidated, and false alarm due to power cutoff can be prevented.

Next, if the power is restored with the announcement disable switch (18) still turned on, for example, warnings such as legally prescribed overpass warnings will be blocked, and an announcement of a sign according to the elevator operation status will be given. The elevator service is very unfriendly. Therefore, even if the emergency announcement prevention means is forgotten to be returned, it is necessary to make an announcement necessary for elevator operation.

Here, a case where the power is restored with the announcement invalidation switch (18) kept turned on will be described.

In process 20, the announcement invalidation switch (18) is turned on, and the process proceeds to process 22. In process 22, the power supply of the elevator control panel is restored, and the announcement compulsory command means (19) is closed. Therefore, the process proceeds to process 21. Processing 21
Since the power source of the elevator control panel is restored, the announcement command contact (16) for power failure or failure is open and the process proceeds to step 23. However, if the elevator detects a failure, the contact is closed, and the process goes to step 24 to make an announcement for the failure. In the process 23, when the elevator control panel starts to close the door, the door close announcement command contact (17) is closed to make a "door close" announcement.

The present invention is not limited to the above embodiment, and the same effects can be obtained in the following modes.

(1) The elevator control panel and the elevator announcement device have been described as separate components, but this function can also be achieved by incorporating the announcement device in the elevator control panel.

(2) The explanation has been given by providing the announcement invalidating means and the elevator announcement device side, but this function can also be achieved by a method of holding this information on the elevator control panel side and sending this information to the announcement device.

(3) The content of the announcement was explained with one power failure / failure response and one normal announcement, but it is obvious that the same function can be obtained even if there are multiple announcements.

〔The invention's effect〕

As described above, according to the present invention, even if the power of the elevator control panel is artificially cut off, it is possible to prevent an erroneous announcement of a power failure / failure response, and further, the erroneous announcement prevention device forgets to return it. However, since the failure response and general announcement can be surely performed if the power source is restored, there is an effect that the elevator users can always obtain necessary information.
