Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information collection systems face a challenge in shortening the measurement data collection cycle for sensor terminals with short cycle requirements, as the cycle lengthens with increasing numbers of sensor terminals, and existing methods to address this are complex and disrupt long cycle data collection.
Innovation Solution
An information collection system with first and second sensor terminals, where the first terminals transmit data in a fixed period and second terminals determine and transmit data in separate periods based on reception requests, allowing for differentiated data collection cycles without overlapping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the information collection terminal collects measurement data from all sensor terminals in a predetermined order, then all sensor terminals can be covered, but the collection cycle increases according to the number of sensor terminals
Solution Approach 1:
The patent divides sensor terminals into two groups: first sensor terminals that transmit measurement data in a predetermined order during a first period, and second sensor terminals that transmit measurement data based on reception requests during a second period. This segmentation allows different collection cycles for different terminal types, resolving the contradiction between comprehensive coverage and collection speed.
2Ease of operation
If the system uses a fixed collection cycle for all sensor terminals, then system operation is simple, but sensor terminals with short cycle requirements cannot achieve their required collection speed
Solution Approach 1:
The patent implements dynamic collection cycles by allowing first sensor terminals to transmit data in a predetermined order during a first period, while second sensor terminals transmit data based on reception requests during a second period. This dynamic approach enables the system to adapt collection cycles to different terminal requirements without complicating overall system operation.
3Productivity
If the system resets after completing collection from short cycle terminals to shorten their collection cycle, then short cycle requirements are met, but long cycle data cannot be acquired and the operation becomes complicated
Solution Approach 1:
The patent segments sensor terminals into first and second groups with different transmission modes. First sensor terminals transmit in a predetermined order during a first period, enabling short collection cycles without system reset. Second sensor terminals transmit based on reception requests during a second period, ensuring long cycle data is not lost. This segmentation eliminates the need for complicated reset operations.
Solution Approach 2:
The patent enables continuous data collection from both first and second sensor terminals without system reset. First sensor terminals continuously transmit in predetermined order, while second sensor terminals continuously monitor for reception requests. This continuous operation maintains short collection cycles for first terminals while preserving long cycle data from second terminals, avoiding the need to interrupt and reset the system.

AI summary
An information collection system includes a sensor terminal group including first sensor terminals and second sensor terminals and an information collection terminal capable of wireless communication with the sensor terminals. The information collection terminal includes a transmission unit that transmits data requests to the sensor terminals and a receiving unit that executes processing of receiving measurement data from the first sensor terminals in a first period, executes processing of receiving reception requests from the second sensor terminals in a second period, and when the reception requests are given, executes processing of receiving measurement data from the second sensor terminals in a third period. The second sensor terminal includes a transmission unit that, when the data requests are given, and when the control unit determines to transmit the measurement data, transmits the reception requests in the second period and transmits the measurement data in the third period.
