Slave Device Status Flag Packet Capacity Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems, when a slave device transmits all device status records to a master device, the packet capacity through the channel between them becomes excessively large, leading to inefficiencies.
Innovation Solution
The slave device is configured to transmit device status records in packets with smaller capacity by generating responses based on status flags, where normal status records are represented with a smaller packet type and abnormal records with a larger packet type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the slave device transmits all device status records to the master device, then the master device can control the operation of the slave device based on complete status information, but the packet capacity through the channel becomes excessively large
Solution Approach 1:
The patent extracts only the necessary status information from the complete device status records. Instead of transmitting all status records, the slave device transmits only those status records that are relevant for the master device to control the operation of the slave device, thereby reducing packet capacity while maintaining the completeness of control-relevant information
Solution Approach 2:
The patent segments the device status records into multiple categories or groups based on their relevance to operation control. The slave device transmits status records in a segmented manner, sending only the necessary segments that contain information required for control decisions, thus reducing the overall packet capacity transmitted through the channel
2Loss of information
If the slave device transmits all device status records, then the master device receives complete status information, but the channel bandwidth usage increases and communication errors may increase
Solution Approach 1:
The patent extracts and transmits only the essential status information required for operation control. By filtering out redundant or non-critical status records, the system maintains information completeness for control purposes while significantly reducing channel bandwidth consumption and the probability of communication errors
3Reliability
If the slave device transmits all device status records, then comprehensive status monitoring is achieved, but power consumption increases
Solution Approach 1:
The patent extracts and transmits only the status records necessary for operational control and monitoring. This selective transmission approach maintains comprehensive status monitoring for control decisions while reducing power consumption by avoiding the transmission of redundant status information that does not contribute to operational control

AI summary
Provided is a method of operating a slave device configured to communicate with a master device and to store a plurality of status flags corresponding to a plurality of device status records, respectively, the method including: receiving a first device status request from the master device; generating a first device status response, wherein based on a value of each status flag of the plurality of status flags, the first device status response includes either a first response type having a first packet capacity or a second response type having a second packet capacity smaller than the first packet capacity; and transmitting the first device status response to the master device.
