... Anticollision 17 Anticollision The purpose of the anticollision sequence is to inventory the LRIS2Ks present in the VCD field using their unique ID (UID). The VCD is the master of communications with one or several LRIS2Ks. It initiates LRIS2K communication by issuing the Inventory request. The LRIS2K sends its request in the determined slot or does not respond. ...
Page 47
... The first slot starts immediately after the reception of the request EOF. To switch to the next slot, the VCD sends an EOF. The following rules and restrictions apply: ● LRIS2K answer is detected, the VCD may switch to the next slot by sending an EOF, ● if one or more LRIS2K answers are detected, the VCD waits until the complete frame has been received before sending an EOF for switching to the next slot ...

Request processing by the LRIS2K 18 Request processing by the LRIS2K Upon reception of a valid request, the LRIS2K performs the following algorithm: ● NbS is the total number of slots (1 or 16) ● the current slot number (0 to 15) ● LSB (value, n) function returns the n Less Significant Bits of value ● ...
Page 49
... The VCD sends an Inventory request frame terminated by an EOF. The number of slots is 16. ● LRIS2K 1 transmits its request in Slot the only one to do so, therefore no collision occurs and its UID is received and registered by the VCD; ● The VCD sends an EOF in order to switch to the next slot. ...
