Crash detection

Accelerometer of device can detect impact or strong hit, so it can be used for crash detection.

It is available in all XG tracking devices: ONE, Light, Light+, StCAN, XtCAN, Tacho, XG47.

a) Adjustments in Logic Template.

Firstly need to identify what should be considered as a crash. For that you should use duration of impact (Crash pulse length), starting power of a hit (G1 force start value) and average power of impact (G2 force mean value).

Below is example of real configuration used by insurance company.

When all thresholds will be fulfilled, event will activate digital input IN15, which is a notification of crash. In order to get this notification as soon as possible, activate it as a trigger of instantaneous message.

This configuration is enough to work with crash, but also you can get detailed information on it if needed.

To get a values, met on impact event, activate following function in masks:

b) Displaying in Monitoring platform.

In case of crash event, device will send to server activated IN15 input.
If you use detailed crash data, it will come in following parameters: crash_data1, crash_data2, crash_data3.

crash_data1 - means maximum acceleration value for the measurement period (G power values);
crash_data2 - average acceleration value for the measurement period (G power values);
crash_data3 - measurement period (set in device settings) (milliseconds).
