Mobilaris 466B User Manual

User Manual: Mobilaris long-life personnel tag
Mobilaris offers a set of various WiFi tags that enables localization of personnel and mobile equipment (such as vehicles or machinery) within the WiFi network. These tags transmit a beacon signal (in CCX blink mode, including the MAC address of the tag) in certain intervals to the WiFi access points network. Using special algorithms, the information is used to determine the position of each tag.
Inside of a network where the Mobilaris Mining Intelligence (MMI) system is not enabled, the tag will continue to function as a standard WiFi tag, sending out CCX blink signals at a defined standard interval or at a factory configured interval.
If a tag is used within a network that supports the Mobilaris Mining Intelligence system, more functionality is enabled:
Tags can be automatically updated over the air
(OTA) with software updates or new configuration (such as blink rates, sleep times, IP address of the receiving MMI etc).
The Tag can be configured to communicate with
MMI when the tag is near an exciter (in order to increase accuracy or to open a gate or similar).
Personnel tags can be configured to communicate
with MMI when the user has pressed a dedicated button on the tag.
The long-life personnel tag is equipped with a powerful battery with a life cycle of up to three years (depending on transmission rates and other configurable parameters).
The tag has the following additional functionalities:
Two multi-functional push-buttons (P1 and P2).
A LED light indicator that provides specific
indications but can also be customized for various indications.
An additional antenna that can sense an optional
exciter (magnetic bubble) and trigger extra beacons and MTP Updates sent up to MMI.
A battery saving mechanism that can put the tag
into sleep mode by decreasing the blink rate and by that increasing the battery time. This happens if the tag has not been moving during a configurable amount of time.
Using the Mobilaris Mining Intelligence system, the tag can be configurated and its firmware can be updated over the air (OTA). This can also be explicitly achieved by a short press of the P2 button in normal state or automatically over a configurable period of time (i.e. every few hours/days).
In the unusual use case where a person configures a tag erroneously so that the tag cannot reach the MMI or the OTA server, there are procedures to get it back to life:
If a tag cannot connect to the MMI system, a
preconfigured fall-back OTA server can be utilized by a long-press on the P2 button.
If the P1 and P2 buttons are being pressed
together for 10 seconds, the tag is forced into a hardware reset.
Using the push-buttons or the battery saving mechanism, the tag can switch between three different states as described to the right:
Normal state
In this state the tag transmits beacon signals in a configurable interval of time. If the tag receives a transmission from an exciter, the tag is triggered to transmit an additional MTP Update to the MMI system with the identity of the exciter in order to increase the accuracy of the positioning.
o If the P1 button is shortly pressed, the LED light
blinks red and the tag will try to connect to the MMI for an MTP Update. This can be used for customer specific operations such as forced ventilation.
o If the P1 button is pressed for 10 seconds, the
LED light blinks red three times and the tag enters hibernation state.
o If the P2 button is shortly pressed, the LED light
blinks green twice and then lights red while the tag tries to connect to MMI in order to check for any new OTA software or configuration.
o If the P2 button is pressed for 10 seconds, the
LED light blinks twice and then lights red while the tag tries to contact a pre-configured fall-back OTA server for a software update/configuration.
Sleep state
If the tags battery saving mechanism senses that the tag has not been moving for a configurable period of time, the tag enters the sleep state. In this state, the tag saves battery life by transmitting beacon signals less frequently using a longer interval of time between beacons (the interval time is configurable). As soon as the tags battery saving mechanism senses a movement of the tag, the tag immediately switches back into normal state.
Hibernation state
This is a state that normally is used when the tag is not in used (i.e. kept in a storage or being transported). In this state, no beacon signals or MTP Updates are being transmitted. This state can only be entered using a specific combination of the push buttons.
o If the P1 button is shortly pressed, the LED light
blinks green and nothing happens.
o If the P1 button is pressed for 10 seconds, the
LED light blinks green three times and the tag switches back to its normal state.
o If the P2 button is shortly pressed, the LED light
blinks red and nothing happens
o If the P2 button is pressed for 10 seconds, the
LED light blinks twice and then stays red while the tag tries to contact a pre-configured fall-back OTA server for a software update/configuration.
If a higher positioning accuracy is needed, inductive exciters can be mounted in required locations.
As the tag gets into the active area of the exciter, it is triggered to transmit a Mobilaris Tag Protocol (MTP) update to MMI with the identity of the exciter. There are exciters in various coverage area sizes, allowing the active area to be customized.
