Solution Overview
Problem
In systems where multiple sensors transmit detection results, there is a risk of collisions between these results, which can disrupt effective environmental control in agricultural settings.
Innovation Solution
A control apparatus that includes a determiner to identify relevant events, an identifier to select target sensors, and a transmission instructor to manage sensor data transmission, reducing collisions by prioritizing sensors that detect indicators critical for environmental control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all sensors transmit detection results simultaneously, then complete environmental monitoring is achieved, but data collisions occur between sensors
Solution Approach 1:
The control apparatus performs preliminary determination of environmental events before sensors transmit data. By identifying which sensors need to transmit based on predetermined events, the system avoids collisions before they occur, resolving the contradiction between reliable transmission and transmission management complexity
Solution Approach 2:
The control apparatus acts as an intermediary between sensors and the central system. It manages transmission coordination by determining event occurrence and selectively instructing target sensors to transmit, thereby preventing data collisions while maintaining monitoring completeness
2Productivity
If multiple sensors continuously transmit detection results, then real-time environmental monitoring is maintained, but transmission collisions disrupt control effectiveness
Solution Approach 1:
Instead of continuous transmission, the system uses periodic event-driven transmission. Sensors transmit only when predetermined environmental events occur, maintaining monitoring efficiency while eliminating collisions that disrupt control effectiveness
Solution Approach 2:
The control apparatus receives feedback about environmental events and adjusts transmission instructions accordingly. By determining which events have occurred and instructing only target sensors to transmit, the system maintains monitoring efficiency while ensuring control effectiveness is not disrupted by collisions
3Quantity of substance
If all sensors are instructed to transmit, then comprehensive data collection is achieved, but transmission collisions increase
Solution Approach 1:
The control apparatus extracts only the necessary sensors that need to transmit based on predetermined environmental events. By identifying target sensors rather than instructing all sensors, the system maintains data collection completeness while reducing transmission collisions
Solution Approach 2:
Different sensors are treated differently based on local conditions. The control apparatus determines which sensors should transmit based on specific environmental events, applying transmission instructions locally rather than uniformly to all sensors, thus reducing collisions while maintaining comprehensive data collection
