Solution Overview
Problem
Surveying systems face challenges in reducing energy consumption, improving operation speed, and automating the resumption of measurements after a break, particularly when the survey pole is put aside, leading to lost line of sight and increased energy usage.
Innovation Solution
A surveying system equipped with an inertial measurement unit (IMU) that detects motion patterns and states in real-time, allowing automatic triggering of actions such as powering down or resuming measurements based on predefined or user-defined motion patterns, thereby optimizing energy use and operation efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the surveying system continuously monitors and tracks the pole, then measurement reliability is maintained, but energy consumption increases
Solution Approach 1:
The system dynamically adjusts its monitoring behavior based on detected motion patterns. When the pole is detected to be in a resting state (through IMU sensor data showing lack of movement), the system automatically transitions to a low-power sleep mode, reducing energy consumption while maintaining measurement reliability through automatic wake-up events triggered by motion detection.
Solution Approach 2:
The IMU sensor continuously provides feedback on pole motion status to the control unit. This feedback loop enables the system to detect when the pole is resting and automatically trigger power-saving modes, while also detecting motion events to resume monitoring, thus balancing energy consumption with measurement reliability.
2Speed
If the surveying system automatically detects motion patterns and triggers actions, then operation speed improves, but device complexity increases
Solution Approach 1:
The system pre-defines motion patterns and associated actions before actual surveying operations begin. When motion patterns are detected through IMU sensors, the corresponding pre-programmed actions are automatically executed, enabling fast response without requiring complex real-time decision-making algorithms.
Solution Approach 2:
The surveying system performs self-monitoring and self-control through integrated IMU sensors and control units that automatically detect motion patterns and trigger appropriate actions without external intervention. This self-service capability reduces the need for complex external control systems while maintaining fast operation.
3Use of energy by moving object
If the surveying system waits for manual resumption after pole is put aside, then energy consumption is reduced, but loss of time increases
Solution Approach 1:
The IMU sensor provides continuous feedback on pole position and motion status. When the pole is detected to be in a resting state, the system automatically triggers a wake-up event and resumes monitoring without requiring manual intervention, thus reducing both energy consumption (through sleep mode) and time loss (through automatic resumption).
Solution Approach 2:
The system is pre-configured with automatic wake-up events that are triggered when specific motion patterns are detected. This preliminary setup enables the system to automatically resume operations without manual intervention, balancing energy savings with minimal time loss.
