Active RFID Tag for Automated Vehicle Telematics Data Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle fleet management systems are inefficient due to manual data collection, leading to errors, delays, and inadequate maintenance and security measures, particularly in parcel delivery operations, where real-time tracking and monitoring are lacking.
Innovation Solution
An active RFID tag system that collects telematics data from vehicle sensors, time-stamps it, and communicates it to a portable data acquisition device, which can alert operators to delivery positions, maintenance needs, and security breaches, using a combination of input interfaces, processors, and data radios for wireless communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual data collection is used by operators with hand-held devices, then data can be collected without additional hardware in vehicles, but the data collection process is time-consuming and produces erroneous or outdated data
Solution Approach 1:
The vehicle itself performs data collection through onboard sensors and an active RFID tag that automatically captures telematics data, eliminating the need for manual data entry by operators. The system serves itself by autonomously monitoring and recording operational parameters such as location, speed, and vehicle status without human intervention.
Solution Approach 2:
The patent replaces the mechanical manual data entry process with an electronic automated system. Hand-held devices and manual recording are substituted by electronic sensors, an active RFID tag, and wireless communication systems that automatically capture, store, and transmit data, eliminating human error and time-consuming manual processes.
2Reliability
If calendar-driven preventive maintenance schedules are used, then maintenance can be planned in advance, but maintenance personnel are not always informed of actual maintenance needs and vehicles may be delayed or rendered out of service
Solution Approach 1:
The system implements continuous feedback through onboard sensors that monitor vehicle conditions in real-time. The active RFID tag captures telematics data and transmits it wirelessly to maintenance personnel, providing immediate feedback on actual vehicle status. This allows maintenance needs to be identified and communicated promptly, enabling timely interventions before vehicles fail or are delayed.
Solution Approach 2:
The system performs preliminary detection of maintenance needs by continuously monitoring vehicle parameters such as engine performance, fuel consumption, and operational hours. By identifying potential issues before they manifest as failures, the system enables proactive maintenance scheduling that prevents vehicle downtime and ensures availability when needed.
3Reliability
If security measures are not automated, then security mechanisms can be simple and easy to implement, but drivers may mistakenly leave doors unlocked and vehicles are susceptible to theft or damage
Solution Approach 1:
The security system operates autonomously without requiring driver intervention. Door sensors and the active RFID tag automatically monitor vehicle security status, detect unauthorized access attempts, and alert authorities or fleet管理人员. The system serves itself by continuously monitoring and responding to security threats without human involvement, eliminating mistakes associated with manual security management.
Solution Approach 2:
The system provides immediate feedback on security status through automated monitoring of door locks, vehicle movement, and unauthorized access attempts. The active RFID tag and sensors detect security events and transmit alerts in real-time, enabling rapid response to potential theft or damage risks without requiring driver awareness or action.
4Productivity
If real-time vehicle tracking and monitoring is implemented, then fleet management efficiency is improved and errors are reduced, but the system complexity and cost increase
Solution Approach 1:
The active RFID tag serves multiple functions simultaneously: it tracks vehicle location, monitors telematics data, enables communication between components, and supports security monitoring. By consolidating these functions into a single multi-functional device, the system achieves real-time tracking and monitoring capabilities without proportionally increasing system complexity or cost.
Solution Approach 2:
The patent combines previously separate systems (tracking, telematics monitoring, communication, and security) into an integrated system centered around the active RFID tag. This merging of functions reduces the number of separate components needed, simplifies system architecture, and lowers overall complexity while maintaining comprehensive real-time monitoring capabilities.
Data Source
AI summary
Data collection and evaluation systems that, in various embodiments, include an active RFID tag for collecting, time-stamping, and storing vehicle sensor data. Examples of the type of data collected include door data, ignition data, oil pressure data, temperature data, speed data, global positioning data, and diagnostic and trouble code data. The system further includes an external data acquisition device, such as a mainframe computer system or a hand-held data acquisition device like an iPAQ. The external data acquisition device includes an RFID interrogator for communicating with the RFID tag, which enables the RFID tag to transmit the time-stamped data wirelessly to the external data acquisition device. The ability of the system to automatically collect and transfer data allows for the automation of fleet management processes, vehicle maintenance and repair processes, and certain security features.
