Next, the operation of the elevator voice guidance system having the above configuration will be explained.

First, the serial transmission method will be explained. In this embodiment, a cyclic scan method is adopted, and the main station 23 side has control over the transmission. The remote station 22 is assigned a predetermined address for transmitting and receiving voice data. Then, the remote station 22 transfers the address data sent from the main station 23 to the transmission line 2.
5, and then inputs audio data sent out from the main station 23 only in the case of its own address, and writes it into the DPRAM 37.

Now, when a command is given to the main station 23 from the elevator control device 21 to provide driving direction guidance to the car 4, the main station 23 sends the address of the car remote station 22 and then sends the voice data for driving direction guidance. It is extracted from the audio data memory 32 and sent to the serial control unit 31.

After recognizing the sent address, the remote station 22 of car 4 sequentially sends the received voice data to D.
When the predetermined amount of data has been written to the PRAM 37, the speech synthesis module 35 reads out the contents of the DPRAM 37, synthesizes the speech, inputs the synthesized speech signal to the AMP 41 for amplification, and gives this amplified signal to the speaker 5 to output the speech. Playback is performed and audio guidance is broadcast to passengers in car 4.

2C also has the configuration shown in FIG. 3 described above, and a specific address is assigned to each remote station to distinguish it from other remote stations.

Therefore, when the main station 23 wants to broadcast audio guidance to any of the cars 4A to 4C, the main station 23 transmits the address assigned to the remote station of the corresponding car, for example, the remote station 22A, and then , when necessary audio data is transmitted, only the remote station 22A to which this address is assigned responds to this transmission, captures the audio data, and writes it into the DPRAM 37.

Thereafter, similarly to the first embodiment, the voice synthesis module 35 reads out the voice, synthesizes it, amplifies it, and broadcasts the guidance from the speaker 5A.

In this way, in the elevator voice guidance system of this embodiment, the voice data memory 32, which must store a large variety of voice guidance information, is located at one location in the main station 23 on the elevator control device 21 side. The voice data is transmitted by specifying the number of elevators A to C that require broadcasting by serial transmission, and the corresponding remote station among the remote stations 22A to 22C sends the voice data to the voice synthesis module 35. By performing voice synthesis processing and reproducing it through the speaker, there is no need to build in voice data memory for each machine as in the past, saving λ memory and simplifying the equipment. This is σ.

[Effect of the invention] As described above, according to the present invention, the audio data memory can be
Since it can be managed in one place, it can be multifaceted, and a variety of information broadcasts can be realized with a simple system structure. Furthermore, maintenance can be simplified by simply changing the audio data memory in one place to change the content of the guidance broadcast.
