Patent Searching and Data


Title:
FAULT DETECTION SYSTEM OF DIGITAL TALKIE DEVICE
Document Type and Number:
Japanese Patent JPH04128897
Kind Code:
A
Abstract:

PURPOSE: To accurately detect output abnormality of voice data regardless of the state of a voice level by comparing the address value of a delimiter code.

CONSTITUTION: A read address specifying means 3 sends out read address values to a voice data storage means 1 in order to output voice data in address order. At this time, a read address monitoring means 5 outputs the voice data or sent-out address values to a delimitation period detecting means 6. The means 3 sends the delimiting code out of the means 1 after specifying all the addresses of the voice data. Simultaneously, the means 6 makes a comparison with the delimiting code address value outputted from a delimiting code address storage means 2 and outputs a delimitation period detection signal once detecting a match. A delimiting code detecting means 4, on the other hand, outputs a delimiting code detection signal on detecting the delimiting code. When the output of the digital talkie device is normal, the delimiting code detection signal and delimitation period detection signal are sent out at the same time.
