  In this specification, the operation operation of the elevator by the elevator maintenance / inspection support system is referred to as maintenance support operation.

  In FIG. 1, an elevator control device 1 controls all functions of an elevator so that the operation state of the elevator can be determined. The elevator control device 1 includes a LAN interface 5 and is connected to the position information providing means 8 and the elevator monitoring center 10 via the router 7 and the Internet line 8.

  Further, the portable terminal 21 possessed by the maintenance staff 20 is connected to the position information providing means 8 through the wireless communication line 22 and the Internet line 7, and measures the position using, for example, the radio waves 23 transmitted from a plurality of GPS satellites 23. The position information and the identification signal set in advance in the portable terminal are periodically transmitted to the position information providing means 9.

  The position information providing means 9 receives the position information transmitted from the portable terminal 21 and the identification signal set in advance in the portable terminal, and determines the distance between the elevator control device 1 and the portable terminal 21 to the elevator control device 1. The transmission operation is performed.

  The elevator monitoring center 10 issues an editing operation command to the rewritable storage means 4 in the elevator control device 1 to the elevator control device 1 from the remote side via the Internet line 8.

  Next, the operation of the maintenance support operation in the elevator control device 1 will be described with reference to FIG.

The storage means 4 in the elevator control device 1 records in advance an identification signal and a next maintenance inspection date and time that are set in advance in a portable terminal possessed by the maintenance staff.
