Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an elevator guidance broadcasting device,
In particular, it relates to improvements in direction guidance broadcasting devices.

[Technical background of the invention]

For elevator guidance broadcasting, a broadcasting guidance device is installed in the elevator machine room, and a speaker is generally attached to the top of the car for the purpose of providing guidance services to elevator passengers. In particular, they are often installed in public buildings that are used by many people with physical disabilities. On the other hand, in recent years, the use of semiconductor-applied equipment has rapidly developed, and broadcast guidance equipment has changed from the conventional tape type to voice synthesis equipment, and as there are no moving parts, maintenance has become much easier (general (maintenance-free), the range of installation of broadcast guidance devices has expanded, and they are now being installed in buildings used by many general users. For this reason, people who work in buildings that use elevators several times a day,
A problem has arisen in that each broadcast announcement seems too loud to the ears. As a result, the method of general service broadcasting is being reconsidered. It is also a good idea to install speakers installed in the hall for passengers, but it is generally possible to hear the sound sufficiently using speakers installed in the car.

By the way, broadcast content generally includes (a) direction guidance, (b) floor guidance, and (c) special guidance. In this case, the contents broadcast every time the elevator moves are the above (a) and (b), and the special information in (c) is often information about abnormal situations such as elevator failure information or earthquake information. In addition, when currently installing broadcast information equipment, buildings with a high public nature must comply with (a) and (b) of the above contents.
(In some cases, (c) is also added.) Generally, the content of (c) is broadcast as a service improvement measure in general buildings.

[Problems with background technology]

However, as mentioned above, it has become common to use speech synthesis equipment as a device, it has become maintenance-free, and it has come to be used in many buildings for the purpose of improving services. (a) Broadcast content of (a) and (b) during times when the elevator is used by people with physical disabilities. (b) When there are many general users, information broadcast to improve service when it is easy to make mistakes when using the elevator. (c) There is a growing need for announcements of abnormal situations and other detailed services depending on the situation.

[Purpose of the invention]

The present invention was made in view of the above-mentioned circumstances, and its purpose is to improve the above-mentioned service broadcast content, provide detailed services to general customers, and eliminate misunderstandings etc. To provide a direction broadcast guidance device for an elevator that can eliminate mistakes when getting on and off.

[Summary of the invention]

In order to achieve the above object, the present invention incorporates a normal direction guidance function that provides directional guidance such as going up or going down every time the elevator stops at a floor. In the case of the highest reversal call, which is the call at the most different position of the elevator, a function is added to provide the above direction guidance when there is a car call and a landing call registered at the floor where the elevator stops, and only the car call is answered. The present invention is characterized in that each of these functions is selectively used.

[Embodiments of the invention]

Hereinafter, the present invention will be described with reference to an embodiment shown in the drawings. FIG. 1a shows an example of the configuration of an elevator guidance broadcasting device equipped with the direction guidance broadcasting device of the present invention. In the figure, 1 is the door close confirmation contact;
2 and 3 are upper and lower direction selection contacts, 4 is an operation confirmation contact, 5 is a call response confirmation contact, 6 is a floor selector, 7
is a special circuit, 8 is a guide broadcaster, 9 is a speaker,
Reference numeral 12 represents a direction guidance detection circuit whose details will be described later, and reference numeral 13 represents a state changeover switch, which is constructed as shown in the drawing.

Here, the contacts 1, 2, and 3 and the guidance broadcaster 8 constitute a first direction guidance device that provides direction guidance every time the elevator stops at a floor. In addition, in the case of the highest reversal call, which is a call in the opposite direction to the elevator movement and is the call at the farthest position where the elevator moves, the direction guidance detection circuit 12 detects that the car call and the hall call are registered at the floor where the elevator stops. Since it provides direction guidance only when responding to a request, it constitutes a second direction guidance device. On the other hand, 13-4-
The floor guidance circuit consisting of 5-6-8 broadcasts guidance on the floor to be stopped based on the position signal of the floor selector (elevator position detection device). Furthermore, 7
The special guidance circuit consisting of -8 makes an emergency announcement according to the conditions of the special circuit 7, and is used to provide information on earthquakes, fires, etc.

On the other hand, a state changeover switch 1 determines whether to broadcast direction guidance with easy-to-misunderstand content or general guidance, that is, to switch between the first and second direction guidance devices.
3, the signal from the direction guidance detection circuit 12 is input to the guidance broadcasting device, or the upper and lower direction selection contacts 2 and 3
Switches whether to input the signal to the position signal input of the floor selector 6. Further, the special circuit 7 is configured to always operate regardless of the state of the state changeover switch 13. (Generally, emergency broadcast contents (earthquakes, fires, etc.) are carried out) Furthermore, when these input signals are input to the guidance broadcaster 8, the contents of the words to be broadcast are selected and outputted to the speaker 9, thereby providing a broadcast guidance service. It is configured to do so. Here, the guidance broadcaster 8 is often based on a tape recorder, but with advances in semiconductors, a voice synthesis device using a microcomputer is now used. The voice synthesizer uses an input control signal to extract voice data from the memory using a microcomputer based on the data written in the memory, and outputs it as a voice signal to make the speaker 9 sound.

FIG. 1b shows details of the direction guidance detection circuit 12, in which the same parts as in FIG. 1a are denoted by the same reference numerals. In the figure, door close confirmation contact 1 is a contact that is released and closes when the elevator landing door is closed, vertical direction selection contacts 2 and 3 are contacts that close until the door is closed after the elevator stops, and upper and lower call detection contacts 17 and 18 are contacts that close when the elevator landing door is closed. (2) D, (2) K of the call state detection circuit 16; (2)U, (3)D, (3)K, (3)
U, (Y)D, (Y)K, (Y)U, (values in parentheses are floor numbers)
is a nominal contact that is held until the door opens after the elevator stops. Further, the upper and lower operation confirmation contacts 14 and 15 are used to maintain the direction in which the elevator has been operating from the time the elevator stops until the door opens when the elevator responds to a hall call that is opposite to the movement of the elevator. It is a point of contact.

Next, conditions for direction guidance according to the present invention will be explained with reference to FIGS. 2a to 2d. Note that the arrow in the figure indicates the direction in which the elevator moves. First, a shows a case in which the call is answered to the highest reversal call in the upward direction, and b shows a case in which the call is answered to the lowest reversal call in the downward direction. The purpose of broadcasting direction guidance in these cases is to prevent passengers waiting at the landing from thinking that if they do not look carefully at the direction lights and hall call lamps, the elevator will continue to move upwards even after the elevator has stopped. This is because there may be a difference. In addition, in cases c and d of the same figure, even though the elevator answered the car call and opened the stop door, the passengers waiting at the hall misunderstood that the elevator had responded to the hall call, and were unable to take the elevator. This is because they get on board. Therefore, by broadcasting these information, we can stop mistakes caused by misunderstanding,
The aim is to improve services. In addition, 10 in the figure
11 indicates a hall call, and 11 indicates a car call.

Next, the operation of the elevator direction guidance broadcasting device configured as shown in FIG. 1 will be explained using FIGS. 2a to 2d. First, if the state changeover switch 13 is set to the door close confirmation contact 1 side, direction guidance and floor guidance will be broadcast every time the elevator moves. on the other hand,
If this is inserted into the direction guidance detection circuit 12 side,
Two types of direction guidance will be performed using the special circuit 7 and under the conditions shown in FIGS. 2a to 2d.

For example, in Figure 1b, if there is a car call on the 3rd floor and a call to descend the landing, and there is also a call above the 3rd floor (Figure 2c), the direction guidance detection circuit 12 will guide you through the state changeover switch 13. Broadcasting will take place. In this circuit, 12 (terminal 3)-1-2-
17-3D-3K-12 (terminal 1 . . . upward guidance output), and the upward guidance signal is input to terminal 1 of the guidance broadcaster 8 and broadcast by the speaker 9. The operating state of each contact is as described above. Here, since the direction guidance is generally broadcast when the door is opened, the door close confirmation contact 1 is included. In addition, the information broadcaster 8
The signal trigger is set to broadcast only when the signal arrives (UP EDGE TRIGGER), so
The guidance broadcaster 8 is constructed so that it does not broadcast over and over again just because an input signal is received.

In the same manner as described above, guidance to other floors and downward direction is also performed. FIG. 2a shows that in general elevators, when the highest reversal call is answered, the direction lights are reversed, so that signal can be used. In this operation, in FIG. 1b, the circuits 12 (3 terminals)-3-18-14-12 (2 terminals) are closed and a downward guidance signal is output.
Here, contacts 2 and 3 are direction selection contacts used for the above-mentioned direction lights, and contacts 14 and 15 are used to know whether the direction of movement has been upward or downward, and to confirm that the door is closed. It is assumed that the contact point 1 is operationally wrapped.

In the above embodiment, the device is configured to give direction guidance when it is easy to mistake it for special guidance, but similarly, it is better to specifically broadcast floor guidance (for example, to upper service floors when there is an express zone). Information on the floor when entering, floor with connection to subway, etc.)
It is also possible to have a configuration in which the information is broadcast at the same time.

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to improve the content of service broadcasting, provide detailed service to general users, and provide an extremely reliable elevator that can eliminate mistakes in boarding and alighting due to mistaken impressions, etc. Direction guidance broadcasting equipment can be provided.
