Smart ignition

Introduction to Smart Ignition Detection functionality

Smart Ignition detection is a functionality which detects ignition by sudden external voltage jumps instead of manually predefined High and Low voltage thresholds.

Smart Ignition Detection functionality logic

 
Figure 1. “Smart Ignition” functionality logic

“Smart Ignition Detection”– detects ignition “on” and “off” automatically by monitoring last “Smart Ignition Duration” seconds of external voltage and comparing it to current external voltage value. If current external voltage value is higher by “Smart Ignition Delta” than external voltage “Smart Ignition Duration” seconds ago, Ignition “on” event is detected. If current external voltage value is lower by “Smart Ignition Delta” than “Smart Ignition Duration” seconds ago Ignition “off” event is detected.







Smart Ignition Detection configuration

New configurable parameters were added under “Ignition Settings” (Figure 2):

• Smart Ignition Enable/Disable – To enable functionality. Parameter is able to be configured if “Ignition Source” has “Power Voltage” configured.

• Smart Ignition Delta (mV) – How much external voltage must change to detect ignition ON or OFF event.

• Smart Ignition Duration (s) – Time interval used for comparing current external voltage against historical external voltage configured seconds ago.
