Management Device Centralizing Identification Data for Fast Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing systems face challenges in quickly returning identification information in response to a requesting command, as they often require processing and communication across multiple devices, leading to slower response times and increased power consumption.
Innovation Solution
An information processing system comprising a management device that acquires identification information from multiple processing devices and writes it into a communication device, allowing the communication device to output commands to specific processing units based on pre-defined write orders, thereby optimizing the response by selecting the appropriate device for command output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the communication unit returns respective identification information pieces acquired from the plurality of processing units, then the identification information is provided to the external device, but the response speed is slow due to processing multiple units
Solution Approach 1:
The management device performs preliminary actions by acquiring identification information from all processing units in advance and storing it centrally before any command requests arrive. This pre-positioning of data eliminates the need for real-time querying of multiple processing units when commands are received, thereby significantly improving response speed while reducing the complexity of on-the-spot processing decisions.
2Reliability
If the communication unit returns identification information from multiple processing units, then complete information is provided, but power consumption increases due to activating multiple units
Solution Approach 1:
The invention extracts the identification information from the processing units and stores it separately in the management device. This separation allows the processing units to remain inactive or in a low-power state while still providing complete identification information through the management device, thus maintaining information completeness while significantly reducing power consumption by avoiding the activation of multiple processing units.
3Measurement precision
If the communication unit queries all processing units for identification information, then accurate matching is achieved, but the processing time increases
Solution Approach 1:
The management device acts as an intermediary between the communication unit and the processing units. It maintains a centralized registry of identification information from all processing units, enabling the communication unit to query the management device directly for accurate matching without needing to contact multiple processing units individually. This intermediary approach preserves matching accuracy while dramatically reducing processing time by consolidating the query function.

AI summary
There is provided an information processing system to increase a speed of returning identification information in response to a received command in the case where an identification information requesting command is received, the information processing system including: a plurality of processing devices each of which includes a storage unit configured to store an identification information piece; a management device configured to acquire the identification information piece from each of the plurality of the processing devices; and a communication device configured to communicate with an external device. The management device writes the identification information piece acquired from each of the plurality of the processing devices into the communication device. The communication device outputs a command received from the external device to one of the plurality of the processing devices on the basis of write orders of the identification information pieces written into the communication device by the management device.
