With the development of industrial automation, remote meter reading has gradually replaced manual data collection. This paper analyzes the issue of low data acquisition success rates in multifunctional power meters, identifying that the high number of functional modules leads to increased failure rates, and analog output (AO) failures affect acquisition continuity. Proposed solutions include replacing transducer functions and adopting RS-485 communication protocols. These measures enhance acquisition efficiency, reduce workload, and provide reliable data support for unit operations.
