2results about How to "Avoid business interruption" patented technology

The application relates to the technical field of wireless communication and data transmission, and discloses a main-backup link digital transmission control method and system of an intelligent fusion terminal, wherein the method comprises the following steps: acquiring multi-dimensional observation parameters of a main link and a backup link and constructing a normalized vector; forming a main-backup link fusion score; constructing short window and long window exponential average values; calculating a score residual, a degradation energy quantization value and a cumulative degradation amount; generating a pre-switching control parameter; performing shunt transmission of a service packet; and completing session context migration and old link release. Compared with the link switching mode depending on received signal strength in the prior art, especially under high-speed movement and base station boundary switching conditions, the technical problems of mis-switching or switching lag are prone to occur. Due to the dynamic weighted fusion score of the multi-dimensional normalized parameters and the score prediction based on trend extrapolation, the application realizes forward-looking identification and predictive switching of the link state.

This invention provides a photovoltaic-energy storage integrated microgrid control method and system for data center computer rooms. The method includes acquiring photovoltaic output power, energy storage state of charge, real-time power consumption of IT and air conditioning loads in the computer room, and voltage and frequency at the common interconnection point. Based on the computer room thermodynamic model, ambient temperature, and predicted IT load for the next time period, the method calculates the air conditioning power consumption feedforward compensation and adjusts the energy storage power scheduling benchmark. Based on the deviation between the predicted and actual photovoltaic power and the energy storage state of charge, the method calculates the IT load interruptibility level index, adjusts the threshold, and sends a load reduction request to the IT resource management system when the index exceeds the threshold. The method calculates the voltage benchmark fluctuation, superimposes it to obtain a voltage control command, and combines the frequency adjustment command generated by the frequency deviation with the adjusted energy storage power scheduling benchmark to generate a control signal that is sent to the photovoltaic inverter and the energy storage converter.
