An adaptive control method and system for a container monitoring terminal

Abstract

This invention discloses an adaptive control method and system for a container monitoring terminal, comprising: acquiring the pulse current response characteristics of a supercapacitor and the ambient temperature; calculating a temperature indicator factor based on the pulse current response characteristics of the supercapacitor, and using the temperature indicator factor to compensate for the ambient temperature to obtain a corrected effective temperature; correcting the effective capacity of a lithium-ion battery based on the effective temperature, and acquiring the lithium-ion battery current to perform coulomb integration to update the battery's state of charge; using an extended Kalman filter algorithm to jointly estimate the battery's state of charge and internal resistance based on the corrected effective capacity; performing trend analysis on the ambient temperature and humidity time series to predict future environmental changes and calculate the risk level; this invention can significantly enhance the robustness and endurance of the container monitoring terminal in complex scenarios such as cold chain transportation, reduce maintenance requirements, and improve overall energy efficiency.
