Buffered Multi-Head Measuring System for Parallel RFID Readout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing measuring systems in industrial automation lack flexibility and efficiency in controlling and transmitting measurement data from multiple RFID read/write heads, as they require serial data transmission and can only have one active element per channel, limiting parallel operation and data transmission.
Innovation Solution
A method and system where measuring elements determine and buffer measurement data simultaneously, allowing for parallel operation and fragmented data transmission via an evaluation module, which reads out the buffered data from each element independently, reducing data loss and enabling targeted data retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If serial data transmission is used with one active element per channel, then device complexity is reduced, but productivity decreases due to inability to operate multiple measuring elements in parallel
Solution Approach 1:
The patent divides the data transmission system into multiple independent parallel channels, each capable of simultaneous operation. Measuring elements are segmented into groups that can operate independently, allowing multiple elements to determine and transmit measurement data simultaneously without interfering with each other, thus resolving the contradiction between productivity and device complexity.
Solution Approach 2:
The patent transitions from a single-dimensional serial transmission approach to a multi-dimensional parallel transmission architecture. By adding the dimension of parallelism across multiple channels, the system enables simultaneous operation of multiple measuring elements while maintaining manageable complexity through structured channel organization.
2Loss of information
If complete data chain transmission is required from all measuring elements, then measurement data completeness is improved, but loss of time increases due to sequential transmission requirements
Solution Approach 1:
The patent implements preliminary buffering of measurement data at each measuring element before transmission. Each element stores its measurement data in an internal buffer, preparing it for simultaneous transmission across multiple channels. This preliminary action eliminates the need for sequential data collection, reducing transmission time while ensuring complete data capture from all elements.
Solution Approach 2:
The patent establishes continuous parallel data transmission across multiple channels, allowing measurement data to be transmitted simultaneously from all active measuring elements. This continuous parallel action eliminates the time loss associated with sequential transmission while maintaining complete data capture, as each channel operates independently and continuously.
3Adaptability or versatility
If targeted separate transmission of information from individual measuring elements is enabled, then adaptability improves, but device complexity increases due to required independent control channels
Solution Approach 1:
The patent segments the control system into multiple independent channels, each capable of targeted communication with specific measuring elements. This segmentation enables selective activation and control of individual elements or groups, providing adaptability while managing complexity through modular channel design. Each channel can be independently configured and controlled, allowing flexible data transmission without requiring complex centralized control.
