The TRUNCATE operation in the ‘Operations’ tab can be used to remove all the EPCs

from this table.

To start and stop the reader, the Reader_commands table is used. Each time a

command is set, the ‘processed’ flag should be set to zero, this will be overwritten back

to 1 when the command executes. To start the reader select the desired reader in the

table and click ‘edit’, set the command to 1 and processed to 0, then click ‘go’. To stop

the reader, the same process is followed, with the command set to 2 and processed set

to 0.

The Tag reads from the reader are held in the tag_reads_simple table. This displays

the tag_read_id, an auto incrementing integer which is unique for each read. Zone

which corresponds to the group of readers were the tag read orginated. Time_stamp

which is representation of the time at which the read occurred (referenced to the

internal clock of the RFID reader), in milliseconds since 00:00 January 1

1970

UTC/GMT.

8. PervasID Dashboard Interface

The PervasID Dashboard Interface is supplied to allow easy evaluation of the

PervasID system. The dials of the dashboard are shown below.

The displays show: the number of unique EPCs detected (as held in the

tag_reads_simple table), the number of reference tags (held in the reference_tags

table), the number of missing tags (tags held in the reference_tags which have not been

found in tag_reads_simple, initially this will be equal to the number of reference tags)

and the resulting reader accuracy which is the number of missing tags divided by the
