<p>The invention provides a system of emergency call inspection for an elevator, capable of precisely determining whether the inspection of an emergency call device is good or not without increasing burden of a monitor at a monitor center side. In the system, at a monitor center device side, a sound signal after reference literal data of a comparison device of a sound inspection part are subjected to the sound conversion via a sound conversion device is sent to a terminal device via a communication processing part and a communication line. In a device, a signal received by the communication processing part is used to enable a loudspeaker of an interphone of an emergency call device in a lift car to make a sound through a sound processing device, and a sound signal obtained by collecting sound with a microphone is sent to the device via a processing part and a line. In the device, signals received by the processing part are subjected to the literal conversion by a literal conversion device through the sound identification processing and used as literal data. According to a comparison result between the reference literal data before conversion and the literal data after the conversion, whether the matching is available is determined, and the comparison result is kept by a storage part.</p> |
