Simcom A7600c1 LTE Module for Intelligent and Realtime Precision Maintenance Scheduler on a Volvo In-Line D16C610 Engine

The intensive usage of the engine requires a real time and intelligent approach on how or when to perform a daily maintenance. Volvo in-line D16C610 engine is specifically installed on a FH16 prime mover truck head dragging a single or double trailer (vessel) weigh about 136.4–140 metric ton for each vessel. Unfortunately, the parameter used for the maintenance schedule is depend only on hour-meter (HM) which shows running hours of the engine regardless the speed, load, or temperature of oil. This faulty parameter therefore made the maintenance schedule inefficient and faulty. A Simcom A7600c1 LTE Module is installed on an ECU as transmitter to feed the data to the central maintenance planner. Based on the data collected by the system such as engine oil temperature sensor (EOTS) and Crankshaft Position Sensor (CPS). The data for precision maintenance schedule based on real time condition of the engine is recorded via Blynk cloud IoT server and exported to a csv file for further process. The device prototype has been installed and tried in a real-world environment and has been proved to raise the value for MTBF about 1.8 hour, which means the unit is failed more rarely. However, the adjustment of HM value has made MTTR value about 0.6 hour, which means the unit needs more time in maintenance session. The oil analysis result using ASTM D5185-18 method also proved that the status changed from mostly “attention” to “normal” due to the change of the oil is now happen more frequent whenever the unit runs the engine faster than the recommended cruising speed given by the factory
