Introduction

Requirements

Summary

The Scan read mode is a generic purpose read mode to be used in read points, where we want information on all the tags passing through.

In that sense it is not designed to be used to perform inventories of static tags.

The Scan Read mode allows two different operation mode

Simple

• 1. All tags in the field are reported periodically

No repetition filter

1. Once a tag has been reported, it won't be reported again until it leave the reader reach for a set time.

Configuration

The Scan ReadMode is under the Autonomous configuration

Options

Check upload period

Examples

Simple operation

This example works as follows:

• • After starting the operation there is a warm up time of 60 seconds. During that time no TAG_SCAN events will be generated

  • Every 60 seconds all read tags generate a TAG_SCAN event

  • All tags that have generated an event enter a silent period of 5 minutes.

No repetition filter

Advanced options

Calibrator filter

It is possible to define a calibrator filter that will work as follows:

1. Once a day it will perform a quick inventory of items in the field.

2. The list of those items will be filtered out, and will never generate Read events

It is configured in the Advanced JSON conf

In the example above the following is used:

{"calibration":{"enable":true,"enableAtStart":true,"hour":12,"min":45}}

That means:

• enable: boolean to enable/disable the filter

• enableAtStart: boolean to enable/disable the generation of the filter when the operation starts

• hour: the hour (0-23) to re-generate the filter EPC list

• min: the minutes (0-59) to re-generate the filter EPC list

This example works as follows:

• • After starting the operation there is a warm up time of 60 seconds. During that time no TAG_SCAN events will be generated

  • Every 60 seconds all read tags generate a TAG_SCAN event

  • Tags that have triggered a TAG_SCAN event will be ignored until they are not read for 10 consecutive minutes
