The invention relates to the technical field of data processing, in particular to an automatic checking system based on RFID and intelligent weighing fusion, and the system comprises an acquisition module, a judgment module, a determination module, a traceability module, a sorting module, an adjustment module and an early warning module. According to the method, multiple key data are collected, and candidate records seriously interfered by metal are rapidly screened out based on RFID phase variance; then, target records which are wrongly recognized and fail to check are determined through identity ambiguity and space-time conflict confidence; and finally, determining a risk sequence by adopting various data, ensuring that an early warning sequence is closely associated with an actual condition, adjusting preset parameters based on historical accuracy and an abnormal number, realizing accurate insight and active early warning of thermal power plant storage concealment registration errors, fundamentally ensuring the consistency of inventory accounts, and improving the accuracy of the thermal power plant storage concealment registration errors. The problems of risk early warning lagging and low identification accuracy caused by excessively depending on single static data are effectively solved.

This invention belongs to the technical field of power system monitoring and relates to an intelligent operation and maintenance risk early warning method for transmission equipment in harsh environments. The method includes the following steps: synchronously collecting sensor and meteorological data; calculating a dynamic benchmark based on an association model and differentially generating state residual signals; monitoring vibration residuals and triggering a hardware interrupt when conditions are met to synchronously capture high-frequency waveforms of leakage current and temperature during fault transients; extracting feature vectors through dimensionality reduction encoding of the data and generating residual coupling fingerprints by combining them with timestamps; mapping the fingerprints to state trajectories and calculating their geometric similarity to standard templates in a fault topology library to generate targeted early warnings; and dynamically adjusting the acquisition parameters and updating the association model based on the early warning results. This invention solves the problem that existing transmission equipment monitoring methods struggle to isolate environmental interference, leading to low early warning reliability and difficulty in accurately characterizing faults.

The utility model relates to a nail gun with resistance absorption, including gun body, drive arrangement, speed reducer, swing arm, push rod and clamping part, drive arrangement, speed reducer and clamping part set up at gun body, the push rod is in the sliding mode and is arranged in the gun body, the push rod's front end is connected clamping part, the push rod is provided with guide block, the guide block has opened guide groove, drive arrangement drives swing arm rotation after the deceleration of speed reducer, makes the sliding portion in the guide groove and pushes the push rod reciprocating sliding, to make the push rod drive clamping part open or clamping. When clamping part encounters greater resistance (such as object too big or foreign matter jam) in the clamping process, the sliding block in swing arm can compress sliding under the action of second spring, thereby absorbing part resistance, avoid motor because of overload leads to blocked rotation, heating even burnout, significantly improve system reliability and service life.
