This invention provides a main and auxiliary power supply switching system and method with configurable power supply priority. The system includes a main power supply, an auxiliary power supply, an output power supply, and a switching circuit. The main power supply and the auxiliary power supply are two independently powered switching power supply circuits. The MCU main control circuit in the switching circuit controls the main and auxiliary power supply switching control circuit to adjust the main power supply voltage, creating a voltage difference between the output voltages of the main power supply and the auxiliary power supply, thereby achieving the switching of the main and auxiliary power supply priorities. This invention can achieve uninterrupted switching between the main and auxiliary power supplies and allows for flexible setting of the power supply priorities of the main and auxiliary power supplies based on actual application requirements. The circuit structure is simple, low-cost, highly reliable, and practical, effectively ensuring the power supply continuity and operational stability of the energy meter under complex operating conditions.

This utility model relates to the technical field of mechanical environment testing and measurement equipment, specifically disclosing a horizontal impact testing machine. The testing machine includes a base, a worktable assembly, a tailstock assembly, and a hammer assembly. The base is equipped with a drive assembly, a guide unit, a table limiting assembly, and a tailstock limiting assembly spaced apart along the working direction. The worktable assembly is movably connected to the table limiting assembly and can reciprocate relative to the table limiting assembly along the working direction; the worktable assembly is equipped with a positive wave generating unit. The tailstock assembly is movably connected to the tailstock limiting assembly, which selectively fixes the tailstock assembly; the tailstock assembly is equipped with a negative wave generating unit. The hammer assembly slides on the guide unit, and the drive assembly pushes the hammer assembly to impact the positive wave generating unit, thereby driving the worktable assembly to impact the negative wave generating unit. This testing machine is used to perform simulation tests according to the requirements of dual-wave impact testing, thereby completing the detection, evaluation, and verification of the product under test.
