  First, in S101, display information (hereinafter, information to be updated) of the elevator to be updated is transmitted from the first transmission / reception means 4, and the process proceeds to S102.

  In S102, the information to be updated transmitted from the first transmission / reception means 4 is received by the second transmission / reception means 5, and the process proceeds to S103.

In S103, the reception availability determination unit 6 determines whether or not reception is possible from the information to be updated received by the second transmission / reception unit 5, and the process proceeds to S104. Whether or not reception is possible is determined by determining the reception quality. If the reception quality is equal to or higher than a predetermined value, the reception is acceptable. The information indicating whether or not reception is possible is referred to as reception enable / disable information . The reception quality can be obtained by a known technique. For example, there are a method using a signal-to-noise power ratio (S / N), a method using a frame error rate obtained by actually demodulating and measuring a parity bit for error correction, and the like. . The predetermined value may be determined in advance, for example, such as S / N is 3 dB or more and the frame error rate is 1% or less, or may be set as appropriate.

  In S104, the reception availability information generated by the reception availability determination means 6 is determined. If reception is not possible, the process proceeds to S105, and if reception is possible, the process proceeds to S106.

  In S105, since reception is not possible, the own car is driven by the own car driving means 9, and the process proceeds to S103. Hereinafter, when it is reception failure, S103 to S105 are repeated. The amount to be driven may be determined in advance, for example, an amount corresponding to 1 meter, an amount corresponding to the first floor, or the like.

  In S107, the information to be updated stored in the first storage means 7 is displayed on the car information display means 8.

  Here, the information displayed on the information display device 3 according to the first embodiment is preferably a landscape image, a commercial of a commercial building, or contact information to a user. Since these update frequencies are several times a day, it is preferable because the elevator can be updated in the time required for one round trip of the hoistway. In the case of these pieces of information, the first storage means 7 is preferably divided into two areas, and the information stored in the first bank of the first storage means 7 is read out in normal times. Is displayed on the car information display means 8, and information to be updated is written to the second bank of the first storage means 7. When this writing is completed, the information is read from the second bank of the first storage means 7. By switching to display by the car information display means 8 by reading, the information can be displayed without losing continuity. New information to be updated may be written in the first bank of the first storage means 7.

  In the first embodiment, if the first transmission / reception means 4 is installed on the reference floor (for example, the first floor), the elevator often waits and stops on the reference floor, so that information can be easily updated and transmitted. Electric power can be further reduced.

  According to the information display system of the first embodiment, for example, even in a super high-rise elevator, the elevator can be moved to a position where communication is possible, so that information to be updated can be reliably transmitted. Moreover, it is not necessary to increase the transmission power more than necessary.

  Further, the display means 8 may be a voice announcement device provided with a speaker, and has the same effect as the present embodiment.

  In the first embodiment, the car driving means 9 is used to drive the car 2, but the car driving means 11 installed on the control panel may be used. One block diagram of an elevator information system according to this modification is shown in FIG.

  The elevator information display system according to the second embodiment shown in FIG. 3 has the same configuration as that of the first embodiment shown in FIG. 1 except for the control panel 10 and the car driving means 11 installed on the control panel 10.

  The operation flowchart can be realized only by replacing S105 in FIG.
