| 摘要 |
The present invention relates to a method of radio communication between columns of a lifting bridge so as to constitute and exploit a bridge consisting of at least two lifting columns selected in an environment comprising a plurality of columns that can be used for the construction and simultaneous operation of several bridges in multichannel mode. The radio channels are selected in a pre-determined frequency band, the exploitation of the bridges thus constructed being aimed at synchronising the columns in the course of the lifting operations and in the event of a fault in at least one column or in the event of an emergency stop. The method comprises three distinct operating phases. On powering up the columns, a first phase of waiting and of scanning is triggered, followed by a second phase of inscribing the columns for the construction of the bridge, and by a third phase of exploitation in the course of which each column of a constructed bridge dialogues with the others in the radio broadcasting mode, with an equal weight for all the columns. |
