Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current calibration methods for drilling equipment sensors are cumbersome and require multiple tools and devices, making it difficult to calibrate complex sensor systems in field conditions without significant time and cost losses, and are prone to measurement errors due to inadequate environments.
Innovation Solution
A method that utilizes the drilling equipment's own sensors and a control unit to calibrate sensors by turning the boom assembly to various angles, measuring turning and inclination values, and calculating deviations using trigonometric functions or the least squares method, allowing for on-site calibration without separate measuring devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional calibration methods using multiple reference devices and inclined planes are used, then measurement precision can be improved, but device complexity and ease of operation deteriorate due to requiring multiple tools and complex procedures
Solution Approach 1:
The drilling equipment calibrates its own sensors using its own boom assembly and sensors, eliminating the need for external calibration equipment. The control unit executes calibration instructions by turning the boom assembly to different positions and using the equipment's own sensors to measure and calculate deviations, making the system self-calibrating.
Solution Approach 2:
The boom assembly serves dual purposes: it performs drilling operations and simultaneously serves as a calibration reference for sensor calibration. The existing sensors and mechanical structure are utilized for both operational and calibration functions, eliminating the need for separate calibration devices.
2Measurement precision
If traditional calibration methods with multiple measuring devices are used, then measurement precision can be improved, but ease of operation deteriorates due to requiring transportation of equipment and specialized personnel
Solution Approach 1:
The system performs self-calibration at the drilling location without requiring external calibration equipment or specialized personnel. The control unit automatically executes the calibration process by controlling the boom assembly movement and processing sensor data, making calibration as simple as running a software program.
Solution Approach 2:
The calibration function is extracted from external calibration equipment and integrated into the drilling equipment's control system. The calibration process is software-based and uses the equipment's own mechanical and sensing components, removing the need for external calibration tools and expertise.
3Measurement precision
If sensors are calibrated in factory environment with sufficient reference devices, then measurement precision is improved, but loss of time increases due to transportation requirements and inability to perform quick on-site checks
Solution Approach 1:
The calibration capability is built into the equipment during manufacturing, but the actual calibration action is performed preliminarily at the drilling site when needed, rather than requiring post-manufacturing transportation to calibration facilities. The system is pre-configured with calibration instructions and capability to perform calibration immediately at any location.
Solution Approach 2:
The drilling equipment performs its own calibration at the drilling location without requiring transportation to external calibration facilities. The control unit automatically executes calibration routines using the boom assembly and onboard sensors, enabling quick on-site calibration and verification without time loss.
