Applicable Model: Tive Flagship (TT-4000)
The following are frequently asked questions about the Tive Flagship (TT-4000) sensor array for motion, shock, acceleration, and orientation detection. These answers do not apply in any way to the Tive Solo.
Q: How are shock events configured?
Shock events are disabled by default to improve battery life. Contact us with the shock event threshold you need after reading this article and we will configure it for you, confirm configuration, and provide the configuration in the Tracker Description if you wish.
Q: Do you measure the acceleration & shock only at the Measurement Frequency or is it always on? When does motion / acceleration / shock data show up on the Tive Platform or Tive API?
A: The shock sensor can be set to always be on! So it can capture any shock at all times.
In addition, at the Measurement Frequency that you've configured, motion / acceleration data is also recorded. At the configured Transmission Frequency, this data is sent to the Tive Platform or API:
- motion / acceleration recorded leisurely at Measurement Interval(s), and
- the top 4 strongest shocks in G's (these are the red lines superimposed over each other)
Upon customer request, we can set your Flagship to transmit all current data at the moment of a Shock Event (at a minor cost in battery drain) but this is only useful if you are actively monitoring the shipment.
Q: How many shocks detectors are there? How sensitive are the shock alerts?
A: The TT-4000 can be configured to sense 2x2 shock levels: sensitive up to 16G/24G and up to 200G. Motion is sensed over a 100ms window. Sensitivity (in Gs) is not based on time or duration, but rather on the threshold set up on each axis.
Q: What are examples of G-force measurements that the Tracker captures? Is it possible to differentiate types of shocks: fall, flip, crash etc?
A: In the Acceleration (G) sensor pane, our customers have seen force magnitudes upwards of 100G.
The XYZ Acceleration (G) sensor pane gives a great understanding of the force components to understand how the tracker has suddenly been: flipped, fallen, or been dropped.
The tracker can experience 100Gs+ across 3 axes when dropped off a desk, by itself, on multiple axes. The tracker dropped from the same height would experience significantly less Gs when attached to the top of a cardboard box that deforms (because the deformation absorbs the shock). You need to test in multiple scenarios to find the shock level that is interesting to be alerted about.
Q: What kind of shock events can I see between 16G and 200G?
A: Dropping a package with a Flagship tracker from 10 cm (4 in) exerts 16 G's on the shock sensor. Events up to 200G can occur depending on the weight and the height of the package when dropped or thrown.
Q: Can I see shock events on the Solo 5G (TT-7000)?
A: Until Summer 2020, configuring & viewing shock events is limited to Tive Support for the Solo 5G.
