Smartrak AVL - how often common events are generated
If an asset is fitted with an AVL (automatic vehicle locator) device, you can expect to see events generated as follows:
Event Icons are found here - https://smartrak.atlassian.net/wiki/spaces/SCP/pages/4423706
Event Name | Description | When will you see this event? |
KEY ON  | Key has been put in the ignition and turned on | When the ignition is keyed on (start of a trip) |
KEY OFF  | Key has been turned off | When the ignition is keyed off (end of a trip) |
POWER ON | When the AVL unit (re)gains external power, event is generated by having a timed relay installed or vehicle having a master switch | Often occurs at the same time as a KEY ON event |
POWER OFF | When the AVL unit loses external power, event is generated by having a timed relay installed or vehicle having a master switch | Depends on the particular setting of the timed relay, but can be anywhere between 30 minutes and 24-hours after KEY OFF |
STOP | Vehicle has been in a stationary position for at least 2 minutes | STOP events are used to calculate idle - see this article for more info - https://smartrak.atlassian.net/wiki/spaces/SCP/pages/78119273 |
MOVING FROM STOPPED | Vehicle had been stopped and now has started moving | MOVING FROM STOPPED event will generate when the speed of the vehicle is above 20km/h |
DIRECTION CHANGE | Vehicle has turned more than 80° while driving i.e. going around a corner | Vehicle going around a corner with a heading of more than 80 degrees |
TRAVELLED | Vehicle has travelled in a straight line | The TRAVELLED event is a placeholder event that is generated every 6-12kms depending on the device’s settings. The TRAVELLED event is often generated when vehicle is travelling on a long straight road (i.e. a motorway), therefore the time between TRAVELLED events can be upwards of 5 minutes |
OVERSPEED | Vehicle has travelled over the set speed threshold | There are two overspeed settings available 1. Standard - there is one singular overspeed threshold, generally set to 101km/h 2. Posted (Real) Road Speed - depends on the posted road speed for each road, between 30km/h and 110km/h - see https://smartrak.atlassian.net/wiki/spaces/SCP/pages/2221408257 For Posted Road Speed, the event is based on the 20-second timer event, for further information please see |
BELOW SPEED LIMIT | When vehicle has been over the set overspeed threshold and reduces speed to be below the overspeed threshold | Vehicle is slowed down to below the set overspeed threshold, or the posted road speed |
ACCELEROMETER EXCEPTION | Accelerating, braking, cornering at a G-force of more than 0.6Gs | When generated by the vehicle. Caused by driving harshly |
BATTERY LOW | Vehicle battery is running low | Did you know, you can set up alerts to be emailed/texted for low battery notifications? Ask us how! |
OFF ROAD | Vehicle has moved more than 25m from the centre of a public road | In NZ, this is used to calculate RUC rebates for diesel vehicles |
ON ROAD | Vehicle has moved from OFF ROAD back onto the road | An ON ROAD event signals the end of an off road period |
