Simpletruckeld(Chicago)Triesten Technologies LLc. Rolling Meadows, Illinois.

As a Networking engineer, supporting to the ELD operations by remotely and held responsible for delivering web enabled transport management system which is integrated with IOT systems.

The IoT allows you to automate and control the tasks that are done on a daily basis, avoiding human intervention. Machine-to-machine communication helps to maintain transparency in the processes. It also leads to uniformity in the tasks. It can also maintain the quality of service. We can also take necessary action in case of emergencies.

Monitoring performance of ELD(Electronic login device) with IOT systems by remotely, it will be synchronize with engine control module to automatically record engine power status and vehicle motion status and more accurate hours of service (HOS) recording.

Assisted with ELD functionality and troubleshooting debug to sync with an mobile application through Wi-Fi to record the vehicle motion status as well as other data to analyze (Date, Time, Location, Driving Time, Engine Hours, vehicle Miles,Driver ID)

Optimum utilization of energy and resources can be achieved by adopting this technology and keeping the devices under surveillance. We can be alerted in case of possible bottlenecks, breakdowns, and damages to the system

This would help in managing revenue & cost of the transportation system and creates standard data displays and data transfer processes, making it easier to demonstrate compliance and faster to share RODS with safety officials
