Description

[Detailed Description of the Invention] The present invention relates to an automatic elevator announcement device,
In particular, the present invention relates to an automatic elevator announcement system suitable for providing information about the surroundings of an elevator car to passengers inside the car.

Conventionally, an automatic elevator announcement system has a main body installed in an elevator machine room or a manager's room, and automatically broadcasts guidance from speakers installed in the elevator car and in the hall. However, this type of automatic broadcasting device does not transmit information about the surroundings of the elevator car, for example.
When automatically broadcasting guidance into an elevator car based on input such as the operation of a car call registration button or the opening/closing of a door, the input signal is input from the car to the automatic broadcasting device in the machine room or manager's room using the tail code. The output signal from the main body must be guided to a speaker installed inside the car for guidance broadcasting, which increases the number of tail cords and increases the voltage level of other voltages passing through the tail cord. The influence of high signal lines can cause problems such as malfunctions or noise coming from the speakers. Further, since the conventional automatic broadcasting device uses a magnetic recording device, the installation space is small and it is difficult to install it inside an elevator car where there is a lot of vibration.

The present invention has been made in view of the above, and an object of the present invention is to provide an elevator automatic system that has good noise resistance, high reliability, and is particularly suitable for calling attention to elevator car doors. Our purpose is to provide broadcasting equipment.

A feature of the present invention is that an automatic broadcasting system for an elevator is configured of an automatic broadcasting system main body equipped with a voice data memory, a voice synthesis section, and a control section, and a loudspeaker installed in an elevator car. is installed on the car door, and when at least one of the output signal of the detector (door safety device) that detects the entrance and exit of passengers or the car door opening/closing signal is input to the control unit, the respective signals from the audio data memory are input. The main body of the automatic broadcasting device is configured to extract an audio signal for calling attention to the door in response to the signal, and input this audio signal to the audio synthesis section.

The present invention will be explained in detail below using the embodiment shown in FIG.

FIG. 1 is a block diagram showing one embodiment of the device of the present invention, showing electrical connection to an elevator door safety device. In Figure 1,
1 to 3 are antennas, 4 is an oscillator, and 5 is a detector that detects the difference between the ground capacitances C ₁ and C ₂ of antennas 1 and 2. The output signal of this detector 5 is used to control the door reversal drive relay 6. and a control unit 10 that controls a voice synthesis LSI (large scale integration) 8 and an audio data memory 9 of the automatic broadcasting device main body 7. The audio signal output from the voice synthesis LSI 8 is broadcasted into the elevator car from a speaker 11 installed in the elevator car to alert passengers. Further, a car door opening/closing signal 12 is also input to the control unit 10. Note that everything except the speaker 11 is installed on the car door 13.

Now, when the car door 13 is about to close, if a passenger approaches the door 13, the antennas 1 and 2
The ground capacitances C ₁ and C ₂ between and ground become unbalanced,
The differential voltage caused by this unbalance is detected by the detector 5. This detection signal operates the door reversal drive relay 6, and the door 13 is reversed.
The control unit 10 starts a control operation in response to this detection signal, takes out an audio signal urging attention from the audio data memory 9, and inputs it to the audio synthesis LSI 8. As a result, the voice synthesis LSI outputs a synthesized voice signal, which is then broadcast from the speaker 11 to warn passengers in the car, such as "The door will not close. Please move away from the door."

According to the embodiment of the present invention described above, since the automatic broadcasting device main body 7 is installed on the car door 13, the input/output signal line can be shortened, and the output of the door safety device, that is, the detector 5 Since the output can be input directly, noise resistance can be improved. Moreover, since noise countermeasures are not required, reliability can be increased. Furthermore, since the car door opening/closing signal 12 is inputted to the control unit 10, before the car door 13 starts to close, a warning voice such as "The door is closing" is emitted from the speaker 11.
can be broadcast to passengers, improving the safety of cantering passengers and blind passengers. Incidentally, since the automatic broadcasting device main body 7 can be compacted, no problem will arise when it is installed on a door inside an elevator car.

As explained above, according to the present invention, the automatic broadcasting device main body is installed at the door of the elevator car, and the door warning sound is broadcast according to the respective states of passengers entering and exiting and door opening/closing. This not only shortens the input/output signal line and improves noise resistance, but it also has the effect of stopping at each floor and reliably broadcasting audio in response to the ever-changing door conditions. .
