Portable Calibration Device for Remote Sensor Self-Calibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sensor calibration methods require removing and transporting remote sensing devices to a designated calibration environment, which is burdensome and may not be feasible in all situations, especially when uncalibrated devices become unusable due to lack of access or timely recalibration.
Innovation Solution
A portable calibration device that wirelessly communicates with remote sensing devices affixed to structures, allowing for on-site calibration by transmitting measurement data to adjust settings and perform self-calibration, eliminating the need for physical removal and transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If remote sensing devices are removed and transported to a designated calibration environment, then calibration accuracy can be ensured, but the calibration process becomes burdensome and may not be feasible in all situations
Solution Approach 1:
A portable calibration device serves as an intermediary between the remote sensing device and the calibration process. This calibration device includes a calibration chamber that can be positioned near the remote sensing device, allowing calibration gases to be delivered locally without requiring the remote sensing device to be transported to a fixed calibration laboratory.
Solution Approach 2:
The calibration system transitions from a fixed-location calibration approach to a mobile calibration approach by introducing a portable calibration device that can move to different locations. This changes the spatial dimension of calibration operations, enabling calibration to occur in the field rather than requiring transportation of the remote sensing device.
2Reliability
If remote sensing devices are transported to calibration environments, then proper calibration can be performed, but operational disruption and time loss increase
Solution Approach 1:
The portable calibration device allows calibration to be performed before the remote sensing device is needed for operation, or during scheduled maintenance windows, rather than waiting for calibration to become necessary. The calibration chamber and gas delivery system are prepared in advance, enabling quick calibration execution.
Solution Approach 2:
The portable calibration device acts as a mobile intermediary that brings calibration capabilities to the remote sensing device's location, eliminating the time-consuming transportation process and enabling calibration to be performed in situ during brief maintenance intervals.
3Measurement precision
If designated calibration areas are required, then calibration standards can be maintained, but system complexity and infrastructure requirements increase
Solution Approach 1:
The portable calibration device is designed as a self-contained unit that combines the calibration chamber, gas delivery system, and control electronics into a single mobile platform. This multi-functional device can serve multiple calibration needs across different locations without requiring separate fixed calibration infrastructure at each site.
Solution Approach 2:
The calibration functionality is extracted from fixed calibration laboratories and consolidated into a portable calibration device. This extraction removes the requirement for designated calibration areas with complex infrastructure, replacing them with a mobile unit that can be transported and deployed as needed.

AI summary
This disclosure is directed to methods, computer program products, and systems for calibrating one or more remote sensing devices in an environment. The disclosed technology relates to a calibration device configured to determine measurement data within an environment. The calibration device may transmit the measurement values, or other calibration data items, to a remote sensing device via a wireless link while the remote sensing device stays with a structure in which the remote sensing device is commissioned to operate. In response to receiving the calibration data items, the remote sensing device may adjust one or more settings of the remote sensing device in order to satisfy a calibration threshold.
