Filtration Monitoring Data Relay Beyond Cellular Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Internal combustion engines face challenges in transmitting filtration monitoring system data to remote data centers when vehicles move out of cellular network range, leading to potential data loss and maintenance delays.
Innovation Solution
A telematics system that receives data from filtration monitoring systems, determines the status of cellular connections, and transmits this data either directly to a remote data center via cellular connection or to an operator device for later relay when out of range, using local wireless connections such as Bluetooth, ensuring continuous data transmission and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is transmitted only via cellular network to remote data center, then data transmission is reliable when network is available, but data transmission fails when vehicle is out of cellular network range
Solution Approach 1:
The system dynamically switches between cellular network transmission and local wireless transmission based on real-time network availability detection. When cellular signal is unavailable, the system automatically transitions to storing data locally and transmitting via Bluetooth to operator devices, ensuring continuous data transmission capability regardless of network conditions.
Solution Approach 2:
The telematics system acts as an intermediary between the filtration monitoring system and the remote data center. It buffers data locally when cellular network is unavailable and relays it through alternative channels (local wireless to operator devices), mediating the data flow to ensure delivery despite network interruptions.
2Reliability
If data is stored in memory device for later transmission, then data transmission reliability improves when out of range, but data storage capacity is consumed
Solution Approach 1:
The system periodically checks cellular network availability and transmits accumulated data in batches when connection is restored. This periodic transmission approach allows efficient use of memory by clearing stored data regularly, preventing memory overflow while maintaining reliable data transmission even during periods of network unavailability.
3Reliability
If dual transmission paths (cellular and local wireless) are implemented, then data transmission reliability improves, but system complexity increases
Solution Approach 1:
The telematics system is designed with multi-functionality, serving both as a cellular network communication device and a local wireless data transfer device. This universal design consolidates multiple transmission functions into a single integrated system rather than requiring separate systems, reducing overall complexity while maintaining dual transmission path capability.
Data Source
AI summary
Data relating to the status of a vehicle, an internal combustion engine powering the vehicle, and various filtration systems that provide filtered fluid to the vehicle and/or internal combustion engine is generated or gathered by an engine control module and a filtration monitoring system. The engine control module and the filtration monitoring system provide the data to a telematics system for transmitting the data to a remote data center (e.g., a cloud computing system, a remote diagnostics system, a maintenance system, etc.). Depending on an availability of a cellular data connection, the data is either sent directly to the remote data center via a network, or indirectly by first transmitting the data over a local connection to an operator device (e.g., a smartphone), which then sends the data to the remote data center once a connection to the network is available.
