Excavator Posture Detection Device for Real-Time Level Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for measuring excavation depth and posture of construction equipment are inaccurate and time-consuming, requiring manual surveying and delaying construction processes.
Innovation Solution
A detection device that acquires posture information from construction equipment, such as buckets, arms, and booms, and wirelessly transmits this information to an interface unit for display, using sensors and communication protocols like Bluetooth or Wi-Fi, allowing for real-time monitoring and processing of level information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual surveying is used to measure excavation depth and transmit surveying results, then the surveying work can be performed, but the excavation work is done under empirical determination causing inaccuracy and delaying construction period
Solution Approach 1:
The patent replaces manual mechanical surveying methods with an automatic measurement system using sensors (accelerometers, gyroscopes, encoders) mounted on the excavator. These sensors automatically detect the position and posture of the excavator components, eliminating the need for manual surveying and providing continuous real-time measurement data for accurate excavation depth monitoring.
Solution Approach 2:
The excavator equips itself with measurement capabilities by mounting sensors directly on its structure. The system performs self-measurement of its own position and posture, eliminating the need for external surveying personnel and equipment. This self-service approach enables continuous automatic monitoring without interrupting the excavation workflow.
2Productivity
If sensors are mounted on excavator and automatic measurement method is used, then real-time monitoring is achieved, but the system complexity increases
Solution Approach 1:
The measurement system is divided into independent functional modules: position detection sensors (accelerometers, gyroscopes) mounted on the body, encoders on hydraulic cylinders, and a control unit for data processing. Each sensor type measures specific parameters independently, and their outputs are integrated by the control unit to calculate overall excavator position and posture, reducing individual component complexity.
Solution Approach 2:
The sensor system serves multiple functions: measuring body position, arm angle, bucket angle, and excavation depth simultaneously. The same sensor suite supports both real-time monitoring and data recording for later analysis, providing multi-functional capability that justifies the system complexity through enhanced productivity.
