<p><P>PROBLEM TO BE SOLVED: To provide the automatic remote program rewriting system of an elevator, which does not perform the remote program rewriting at the time when the telephone line is used in the past, but performs the remote program rewriting after waiting for the time zone in which the telephone line has not been used in the past. <P>SOLUTION: A remote rewriting system 4 compares version information of the present program with program information of the latest version, and when the program information of the latest version is newer, the remote rewriting is immediately performed by sending the program of the latest version to a remote monitoring device 2 via the telephone line and outputting its rewrite command unless at the time when the remote monitoring data have been sampled and any failure has been alarmed in the past, and at the time when any remote monitoring data have been sampled or any failure has not been not alarmed in the past, the rewriting is not performed, but the remote rewriting is performed after waiting for the time zone in which the remote monitoring data have not been sampled, or any failure has not been alarmed in the past. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
