Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an automatic announcement device for an elevator, and in particular, an automatic announcement system suitable for making a floor announcement and a driving direction announcement when an elevator reaches a destination floor. The present invention relates to broadcasting equipment.

[Background of the invention]

Conventionally, automatic elevator broadcasting equipment has been designed to broadcast guidance by installing the broadcasting equipment in the elevator machine room or control room, and connecting it with a speaker installed in the elevator car using a tail cord. Noise leaks into the signal line that transmits the broadcast signal due to the voltage of other signal lines passing through the tail cord, and this noise is emitted from the speakers, causing harshness when riding in an elevator or making it difficult to hear information announcements. There was a problem. In order to prevent the broadcasting signal line from being affected by other signal lines, it is possible to install an automatic broadcasting device in the car and connect the speakers to the dedicated signal line. Because it used a magnetic recording device that uses
Not only is it difficult to maintain performance if the device is installed in an elevator car that experiences a lot of vibration, but it is also difficult to secure installation space due to its large size.

Incidentally, in recent years, an inexpensive speech synthesis device using semiconductor elements has been developed, and it has become possible to provide an automatic elevator announcement device that solves the above-mentioned problems.

However, in order to have this broadcasting device broadcast guidance in accordance with the elevator status, a corresponding control signal is required, and the method of supplying this control signal from the signal circuit of the control panel installed in the elevator machine room is difficult. Depending on the type of broadcasting, a large number of signal lines are required, and a lot of time is spent connecting these signal lines in the machine room and in the car. In addition, in order to secure such a large number of signal lines, it may be necessary to add a tail cord in some cases, making it expensive. Particularly when installing into an existing elevator, if such a situation occurs, not only will the cost of wiring work be added, but the elevator will have to be stopped for a long time for this wiring work, which is a problem. .

[Purpose of the invention]

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to install an automatic elevator announcement device that makes floor announcements and operating direction announcements when the elevator arrives at its destination floor. An object of the present invention is to provide an inexpensive automatic elevator announcement device with excellent workability that eliminates the need for a dedicated line between the machine room and the car to control the automatic announcement device, and can significantly reduce construction time. .

[Summary of the invention]

A feature of the present invention is that the control signals for operating the automatic broadcasting device are a car position signal, a driving direction signal, and a destination floor arrival signal that can be taken in by the elevator car, and a predetermined period of time after the destination floor arrival signal is input. It is equipped with a delay means that outputs the signal after the elapsed time, and when the destination floor arrival signal and the car position signal are input to the automatic broadcasting device, the floor guidance broadcast is performed, and when the driving direction signal and the output from the delay means are input, the driving direction is output. The reason is that we decided to broadcast information.

Next, the operation of the above configuration will be explained.

Now, when the elevator car is waiting on the first floor with the door closed, if the upper hall call button on the second floor is pressed, the ascending operation relay is energized by a known circuit (not shown) and the elevator car is waiting with the door closed. The car runs towards the second floor, and the elevator car moves towards the second floor.
When reaching the floor, the floor relay is energized by a known circuit (not shown), so that the respective contacts 61L and 51F are closed. Furthermore, when the elevator arrives at the destination floor, a door open command relay is energized by a known circuit (not shown), so its contact 10
2D is closed. As a result, a voltage is applied to the floor indicator light 2L on the second floor and it lights up, and this lighting voltage is converted into a predetermined voltage value by the floor detector 2D and used as one input signal of the AND element 2A. The voltage of the door open relay 8R is outputted, and the door open relay 8R is also excited, and the voltage of the door open relay 8R when excited is detected by the destination arrival detector 8D as a destination arrival signal and converted into a predetermined voltage value. After that, it is inputted as the other input signal of the AND element 2A. When the AND element 2A receives the output signals from the floor detector 2D and the destination arrival detector 8D, the control circuit 1P reads message data from the audio data memory 1M so as to broadcast guidance accordingly. It controls the voice synthesis section 3P which converts the signal into a voice signal and outputs it from the loudspeaker 1K. In this way, when the elevator arrives at the daily floor and the doors begin to open, an announcement of the arrival floor is made to notify passengers. Further, the voltage signal of the door opening relay 8R detected by the destination arrival detector 8D is input to AND elements 6C and 7C which are outputted after being delayed for a predetermined time by a delay circuit 8T.

The elevator is currently in ascending operation, and the ascending operation relay is energized. After the elevator stops, if a call is registered for a floor above that floor, the ascending operation relay is energized by a known circuit (not shown). The contact 61L remains closed and the upper direction light 6L remains lit. When the upward direction light 6 is lit, the driving direction detector 6D detects this and outputs it to the AND element 6C, so this AND element 6C announces the upward driving direction to the control circuit 1P. Issue a command. By this ascending operation direction announcement command, the control circuit 1
P reads the message data from the voice data memory 1M and controls the voice synthesizer 3P so that the message data is outputted as a voice signal from the loudspeaker 1K, whereby the elevator user is prompted to operate the elevator. You can know the direction without looking at the direction lights installed at the landing.

In this way, the control signals for floor announcements and driving direction announcements are provided by the position indicator lights, direction lights, and door opening relays provided in the elevator car, and the timing of announcements for floor announcements and driving direction announcements is as follows: Using the energizing voltage of the door opening relay, floor announcements are made when this voltage is detected, while driving direction announcements are made as a signal after this is delayed by a delay circuit. When installing an automatic elevator announcement system that makes floor announcements and operating direction announcements when the elevator arrives at its destination floor, there is no need to install a dedicated signal line from the machine room to control the automatic announcement system. Moreover, it has become possible to provide an inexpensive automatic elevator announcement device with excellent workability, which allows work to be carried out using only the car, thereby significantly reducing construction time.
