Integrated Volt-Ampere Meter and Safety Protection Controller Hardware Design
Pain Points (Public)
Standard digital panel meters only provide passive display without automated cutoff capabilities, while industrial motor protection relays are too bulky and costly for integration into compact pump assemblies. Operating pump motors without sub-cycle electrical trip logic leaves equipment vulnerable to stator burnout during supply voltage sags, overcurrent during locked-rotor conditions, or mechanical seal damage caused by dry-run undercurrent.
Suggested Approach (Public)
Engineer an integrated embedded protection controller combining continuous electrical metering with autonomous safety interlocks. Utilize high-accuracy shunt resistors and ADC sampling with an MCU like an STM32, paired with analog window comparators and relay driver circuits to execute immediate power isolation when voltage or current drifts outside safe operational thresholds.
