Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Advantages of the Invention] The present invention relates to automatic announcements for elevators, and particularly to an automatic announcement system for elevators having entrances and exits on both sides of a car.

[The backbone of invention]

Conventionally, for automatic elevator corner guidance, a single speaker is provided in the car, and broadcasts that match the broadcast activation conditions have been made, as in, for example, Japanese Utility Model Publication No. 59-25821. However, in elevators where cars are located on both sides, it is difficult for passengers to tell which side the door will open, even if they are guided to the arrival floor.

[Purpose of the invention]

An object of the present invention is to provide a system that allows passengers to naturally recognize which door actually operates out of two doors provided in a car using an automatic broadcasting device.

[Summary of the invention]

The key point of the present invention is that speakers of an automatic broadcasting device are installed near the two doors of the car, and the hall button pressed by the waiting hall customer,
Alternatively, depending on the button pressed by the passenger, the speaker next to the door that actually operates can be activated to automatically broadcast floor information, etc., so that each button can naturally recognize the n that actually operates. [Embodiment of the Invention] Hereinafter, an embodiment of the present invention will be described in a poem using Figures 1 and 2.
To explain, FIG. 1 shows an example of mounting a speaker. Speakers 3 and 4 are installed on the ceiling near the front door and the rear door, and these speakers connect from the sound source 30 through the amplifier 31 and then through the relay contacts using the circuit shown in Figure 2. - or through B;
Connect each. Signal IFC~nFC1 becomes 1 when a front hall or car call occurs, and becomes 0 when service ends for that call. Signal IFC~nFC1 becomes 1 when a rear hall or car call occurs, and service ends for that call. and 10"
The signal ILIC-nBC indicates the position of the car, and the signal ILIC-nBC indicates the position of the car.
F-nF is input to the AND element 35 for each floor, the output front side signal is input to the NOR element 23, and the rear side signal is input to the OIt element 24.

The output of NOR element 23 is connected to relay F27
connected to the input of element 26, and the output of OR element 24 is NAN
Connect to the other input of D element 26.

NANL) The output of element 2G is connected to relay BK.

According to this embodiment, for example, when the hall button on the back side of the first floor is pressed and the elevator moves to another floor 111f, the hall charm signal IBC on the back side and the position signal I when arriving at the first floor are transmitted.
F causes the output of the zero element 24 to become "l". On the other hand, since there is no front-side hall signal, the output of the NOR element 23 becomes ``1'', and the relay F is not turned on, and the output of the NAND element 26 becomes ``l'', so the output becomes 0''. When relay B is turned on, contact B is turned on when IJI/-B is turned on.
is closed, and the elevator guidance announcement is played from a speaker 4 provided near the rear door. Therefore, the passenger can naturally recognize the direction of the sound, that is, the opening of the rear door, and can smoothly get off the car.

Also, if a front-back sum signal on the same floor occurs, NAND
First, relay F was turned on by element 26 to broadcast from the front side, and after the front side chain signal was set to "Opp", relay B was turned on to enable broadcast from the rear side. 21 in the figure.

〔Effect of the invention〕

According to the present invention, passengers can naturally recognize the opening of a door based on the direction of the broadcast sound.

Claims (1)

[Scope of Claims] 1. In an elevator with entrances and exits on both sides of the car and equipped with an automatic broadcasting device, speakers for automatic broadcasting are provided near the doors on both sides of the car, respectively, and are operated. An automatic elevator broadcasting device characterized by sounding a speaker next to the door. 2. In claim 1, when there is a strong correlation between broadcasting and door operation, such as arrival floor guidance, direction guidance, door operation guidance, etc., the speaker on the side of the door to be operated may be sounded. Features of automatic elevator broadcasting equipment.
