Gateway Data Acquisition Area Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional information processing systems face challenges in acquiring data from a large number of communication devices, as they exceed the maximum allowable data reception limit, leading to incomplete data acquisition when there are many unspecified devices or sensors.
Innovation Solution
An information processing system that includes a gateway (GW) which adjusts the data transmission request area by adjusting the advertisement field strength, allowing it to receive the maximum allowable number of responses from portable communication devices, and extends or narrows the area based on response thresholds to manage data acquisition effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the information processing device transmits requests to all communication devices in a large area, then more data sets can be acquired, but the number of responses exceeds the maximum allowable number
Solution Approach 1:
The gateway divides the large transmission area into multiple smaller regions and performs segmented data acquisition. It transmits requests to one region at a time, collects responses, then moves to the next region. This segmentation allows the system to acquire data from many communication devices across a large area while keeping the number of concurrent responses within the maximum allowable limit, thus resolving the contradiction between acquiring more data sets and maintaining acquisition efficiency.
2Reliability
If the information processing device narrows the transmission request area to stay within the maximum allowable number of responses, then data acquisition stability is maintained, but the total number of data sets that can be acquired is limited
Solution Approach 1:
The gateway dynamically adjusts the transmission request area based on the number of responses received. When the response count is within the maximum allowable number, the gateway expands the area to acquire more data sets. When the response count approaches the limit, the gateway narrows the area to maintain stability. This dynamic adjustment allows the system to both maintain acquisition stability and maximize the total number of data sets acquired.
Solution Approach 2:
The gateway continuously performs data acquisition by sequentially moving through different regions rather than stopping after one area is exhausted. After completing data collection in one region, it immediately transitions to the next region and continues acquisition. This continuous action ensures that the system maintains stable operation within response limits while progressively acquiring the maximum possible number of data sets across the entire coverage area.
3Device complexity
If the information processing device uses sequential transmission requests to registered identifying information, then the system structure is simple, but data acquisition is incomplete when there are unspecified communication devices
Solution Approach 1:
The gateway performs preliminary actions by transmitting requests to unspecified communication devices in the area before finalizing the data acquisition process. It sends out request signals that can be received by any communication device within the transmission area, not just pre-registered devices. This preliminary action ensures that data from unspecified devices is captured, improving completeness while maintaining relatively simple system structure through the use of broadcast-style requests.

AI summary
An information processing system includes a GW and a portable communication device. The GW includes a transmitter that transmits, to the portable communication device that is located within a given area, a request to transmit information; a receiver that receives a response to the request to transmit information from the portable communication device; and a data acquisition controller that, when the number of responses received is larger than a maximum allowable number to the GW, adjusts the area to which the request to transmit information is transmitted such that the number of responses is equal to or smaller than the maximum allowable number and that, when the number of responses is equal to or smaller than the maximum allowable number to the GW, adjusts an area to which the request to transmit information is transmitted, which is an area different from the area to which the request has been transmitted.
