Sensor Relay Apparatus Batch Transmission Overhead
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sensor relay systems experience increased overhead time and reduced data transmission rates due to the sequential transmission of sensor data from multiple sensor terminals, leading to inefficiencies as the number of terminals increases.
Innovation Solution
A sensor relay system with a communication control unit that compares transmission data amounts from sensor terminals to a preset threshold, enabling or disabling data transmission only when the amount exceeds the threshold, and accumulating data for batch transmission, thereby reducing the frequency of communication method switches between terminals and relay modules.

Engineering Contradiction Analysis
1Ease of operation
If sensor data are relayed and transferred sequentially from multiple sensor terminals, then each terminal can be connected and transmitted individually, but the overhead time increases and transmission data rate degrades as the number of terminals increases
Solution Approach 1:
The patent combines multiple sensor data transmissions into a single batch transmission. The sensor relay apparatus accumulates data from multiple sensor terminals and transmits them together in one operation, rather than handling each terminal separately. This merging approach reduces the number of communication link establishment operations and maintains connection states, thereby reducing overhead time while preserving the ability to handle individual terminals.

3Speed
If communication link is established via the communication network upon delivery of sensor data, then data can be transmitted in real-time, but the activation/sleep state of the wireless module increases overhead time
Solution Approach 1:
The patent performs preliminary actions by establishing communication links in advance and maintaining them in an active state. The sensor relay apparatus maintains connection states with sensor terminals before actual data transmission occurs, so that when data needs to be transmitted, the communication infrastructure is already ready. This eliminates the need for repeated activation cycles and reduces the overhead associated with activation/sleep state transitions.

AI summary
In a sensor relay apparatus (10), a communication control unit (13) receives sensor data from a sensor terminal (ST) via a terminal module (11) when a transmission data amount related to the sensor data to be transmitted from the sensor terminal (ST) is equal to or greater than a determination threshold. This can reduce the overhead time taken at the time of the transmission of the sensor data.
