Train Telemetry Data Aggregation and Transmission Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing telemetry systems on trains face challenges in managing data transmission from multiple telemetry devices, leading to increased data costs, data packet corruption, and battery degradation due to simultaneous communication and continuous data transmission.
Innovation Solution
A first telemetry device detects nearby telemetry devices, initiates a negotiation process, aggregates status data, and identifies a designated telemetry device to manage data transmission, allowing it to transmit aggregated data and configuration information to optimize communication and reduce network congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple telemetry devices transmit status data simultaneously over the network, then complete monitoring coverage is achieved, but data traffic increases leading to network congestion and data packet corruption
Solution Approach 1:
The patent combines status data from multiple telemetry devices into a single aggregated data structure that includes device identifiers and status information from all devices. This merging approach reduces the total number of separate transmissions required while maintaining complete monitoring coverage, thereby reducing network congestion and data packet corruption.
Solution Approach 2:
The patent introduces a designated telemetry device that acts as an intermediary between other telemetry devices and the central server. This intermediary collects status data from multiple devices, aggregates it, and transmits it in a consolidated manner, reducing the overall data traffic volume while ensuring reliable transmission.
2Reliability
If each telemetry device transmits data independently at regular intervals, then comprehensive data collection is achieved, but data costs increase and network bandwidth is wasted
Solution Approach 1:
The patent merges data transmission operations by having multiple telemetry devices contribute their status information to a single aggregated data structure that is transmitted once. This eliminates redundant transmissions and reduces data costs while maintaining comprehensive data collection from all devices.
Solution Approach 2:
The designated telemetry device performs multiple functions: it collects status data from other devices, aggregates the information, manages transmission timing, and handles communication with the central server. This multi-functionality reduces the overall transmission burden and associated costs.
3Reliability
If all telemetry devices communicate simultaneously using the same communication resources, then real-time monitoring is achieved, but battery power is drained rapidly
Solution Approach 1:
The patent implements periodic action by having telemetry devices transmit data at scheduled intervals rather than continuously. The designated device aggregates data and transmits it periodically to the central server, reducing battery power consumption while maintaining real-time monitoring capability through regular updates.
Solution Approach 2:
The patent extracts the communication burden from individual telemetry devices by designating one device to handle all external communications with the central server. Other devices only need to communicate with the designated device, significantly reducing their power consumption while maintaining monitoring responsiveness.
4Productivity
If a single central device aggregates and manages all data transmission, then network efficiency is improved, but the device complexity increases
Solution Approach 1:
The patent segments the telemetry system into two functional groups: designated devices that handle aggregation and external communication, and non-designated devices that focus on local data collection. This segmentation improves overall transmission efficiency while distributing complexity differently across devices rather than concentrating it all in one device.
Data Source
AI summary
The present disclosure relates to managing data transmission from a plurality of telemetry devices onboard one or more trains. The plurality of telemetry devices comprises a first telemetry device and one or more second telemetry devices in a vicinity of the first telemetry device at an instant of time. The first telemetry device is configured to detect presence of the one or more second telemetry devices, and to initiate a negotiation process for identifying a designated telemetry device from the one or more second telemetry devices. During the negotiation process, status data associated with the telemetry devices are aggregated. The aggregated status data is further processed to identify a designated telemetry device from among the telemetry devices. The designated telemetry device performs actions for managing data transmission from the telemetry devices based on the aggregated status data.
