Abstract
A system and method for determining adverse conditions associated with a chemical indicator in an aquatic environment monitoring system in which reference illumination from an optical reader is used to illuminate a chemical indicator. Response from the reference illumination is used to determine a confidence value that can be part of an analysis associated with a measurement illumination response to produce a confidence adjustment instruction for possible action on the measured response value.
Claims20
A method for determining error in a chemical indicator reading of an aquatic environment monitoring system, the method comprising:
- illuminating a first region of a first chemical indicator of a chemical indicator apparatus with a first reference illumination from an optical reader of the aquatic environment monitoring system;
- measuring a first reference response from the first reference illumination;
- comparing the first reference response for a deviation from a predetermined trusted reference value stored in a memory of the aquatic environment monitoring system;
- determining a first confidence value from said comparing the first reference response to the predetermined trusted reference value;
- illuminating a second region of the first chemical indicator with a first measurement illumination;
- measuring a first measurement response from the first measurement illumination;
- and
- generating a confidence adjustment based on the first measurement response and the first confidence value.
A machine-readable hardware storage medium including machine-executable instructions for performing a for determining error in a chemical indicator reading of an aquatic environment monitoring system, the instructions comprising:
- a set of instructions for illuminating a first region of a first chemical indicator of a chemical indicator apparatus with a first reference illumination from an optical reader of the aquatic environment monitoring system;
- a set of instructions for measuring a first reference response from the first reference illumination;
- a set of instructions for comparing the first reference response for a deviation from a predetermined trusted reference value stored in a memory of the aquatic environment monitoring system;
- a set of instructions for determining a first confidence value from said comparing the first reference response to the predetermined trusted reference value;
- a set of instructions for illuminating a second region of the first chemical indicator with a first measurement illumination;
- a set of instructions for measuring a first measurement response from the first measurement illumination;
- and
- a set of instructions for generating a confidence adjustment based on the first measurement response and the first confidence value.
