How long does a dual-sensor redundancy comparison experiment take?

Depending on the verification goal, the experiment's overall duration can range from 14 to 90 days. A detailed timetable is provided below:

1. Basic performance verification, which takes 14–21 days to complete and just confirms that the new algorithm is superior to the previous one. Regular production anti-interference testing should be conducted consistently for a minimum of 5000 production cycles over a period of 14 days. The sample size is adequate to provide steady false alarm rate data and eliminate random oscillations. Fault simulation testing can be incorporated into regular testing and takes an extra two to three days to do, but it doesn't have to be very time-consuming. Appropriate situations include upgrading and validating current solutions, as well as engineering transformation in small and medium-sized industries. This time frame is adequate to draw trustworthy findings.

2. Algorithm Development/Module Decomposition and Verification: 30-45 days in total. At least ten to fourteen days of testing are needed for each experimental group. The period is longer than thirty days, with two to three experimental groups for module verification in addition to a baseline control group. "Sequential testing" can reduce the overall time by running various groups one after the other on the same hardware for ten days each, for a total of thirty days for three groups. Compared to parallel testing, this results in lower hardware expenses.

3. Extra Ninety Days for Long-Term Stability Verification (Adaptive Aging Capability Verification). After basic testing, the algorithm must run continuously without modifications for ninety days if it is required to confirm how well it adapts to sensor aging. To ensure long-term stability, the false alarm rate should be computed on a monthly basis and its rate of change should be tracked.

Simulated aging tests can be utilized in place of this stage if only feasibility verification is necessary and long-term stability data is not needed. One month should still be the maximum amount of time.

Quick Reference for Selection:

Table Verification Goal Suggested Total Time

14 days of engineering modification and verification that the new method is superior to the previous one

30 days of algorithm development and module effects analysis

Finalizing the product formally and confirming its long-term dependability 90 days of long-term testing plus 14 days of basic testing equals 104 days.

A minimum of 14 days should be allotted for testing. Unreliable results and statistical mistakes will result from a small sample size. To guaranty enough coverage of operating cycles, it is advised to lengthen the testing period for each group by three to five days for slow-variable process industries.
