Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current calibration methods for measuring circuits in industrial processes are cumbersome, requiring two workers and manual recording of results, leading to inefficiencies and potential errors due to the need for coordinated field and control room operations and excessive communication.
Innovation Solution
An automated method and system for calibrating measuring circuits, where a single worker can connect a calibrator to the circuit, feed an impulse, read results in the control room, and store both digitally, using a dedicated server or cloud storage, with options for wireless data transfer and delay compensation to account for signal variations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional calibration method with two workers is used, then measurement accuracy can be verified, but calibration time and operational complexity increase significantly
Solution Approach 1:
The measuring circuit performs self-calibration by automatically comparing its measurements against reference values stored in memory. The system autonomously identifies calibration deviations and generates correction factors without requiring external intervention, eliminating the need for multiple workers and manual coordination while maintaining calibration accuracy.
Solution Approach 2:
The system continuously monitors measurement values, compares them against reference values, and automatically applies correction factors based on the detected deviations. This closed-loop feedback mechanism ensures calibration accuracy is maintained while reducing the time required compared to manual calibration methods.
2Measurement precision
If traditional calibration method with manual recording is used, then calibration results can be obtained, but error potential and operational complexity increase
Solution Approach 1:
The system replaces manual mechanical operations (writing down results, verbal communication between workers) with automated electronic data processing. Measurement values and reference values are automatically stored in memory, compared computationally, and correction factors are generated and applied automatically, eliminating human error and reducing operational complexity.
Solution Approach 2:
The measuring circuit autonomously performs the entire calibration process including data recording, comparison, and correction factor application without requiring manual intervention for each step, thereby eliminating error-prone manual operations while simplifying the overall process.
3Productivity
If automated calibration is implemented, then calibration efficiency increases, but system complexity increases
Solution Approach 1:
The measuring circuit integrates multiple functions into a single system: it performs normal measurements, stores reference values in memory, automatically compares measurements against references, generates correction factors, and applies corrections. This multi-functionality achieves automated calibration efficiency without requiring separate dedicated calibration equipment, thereby limiting the increase in system complexity.

AI summary
The present invention describes an automatic calibration method for a measuring circuit for example in an industrial automation or handling process, where only one person is needed to manage the entire procedure. The components are a calibrator (11) which the worker in the field has with him, which can be connected to the starting end of the measuring circuit in order to give an impulse. The quantity to be measured/calibrated has not been limited. The measurement result is seen at the end of the measuring circuit on a screen of the control room, i.e. DCS (13). Depending on the alternative embodiment, the measured numerical value can be steered either to a dedicated server (14) over an OPC connection, and onwards wirelessly or via Ethernet back to the calibrator (11). One alternative is to use a smart device (16) which the worker has, with suitable applications, to which the measured data can be sent over a network, and the data is also presentable in a user-friendly manner in such an application. Thus, the data can be sent onwards to the calibrator (11) in the field over a BT connection. A third alternative is a direct sending of the measurement result from the control room (13) to the calibrator (11), whereby a 3G/4G/5G network, a Wifi, Bluetooth or Ethernet connection can be used for sending the data. A delay module (15) manages mutual temporal synchronization of the data i.e. numerical pairs. The data can be stored in a spreadsheet, matrix or graphic form in a desired place, such as in the calibrator's (11) own memory or in a desired server for example in a cloud.
