The invention relates to a power failure protection method and system for storage server equipment and a computer device, and the method comprises the steps: monitoring an output signal of a power supply unit through a CPLD, and generating a non-shielding interruption signal when the output signal of the power supply unit is recognized to be abnormal; the power supply switching control unit controls a power supply mode to be switched from the power supply unit to the battery backup unit, controls related necessary hardware to enter a core closing mode through the ACPI and hardware cooperation module, and interrupts power supply to unnecessary hardware; controlling a dirty data identification unit to read a dirty data bitmap marked by the storage server equipment, and positioning dirty data to be protected in a memory of the storage server equipment; the dirty data transferred and stored in the preset storage unit are verified through the cyclic redundancy check unit, when the dirty data passes verification, the storage server device is controlled to execute the shutdown process, and when the power-on signal is received again, the dirty data are read from the preset storage unit and recovered to the memory cache.

This invention relates to an emergency power supply distribution and energy storage wall system, comprising an integrated wall-type shell, a dual-busbar power distribution architecture, a multi-mode seamless switching module, a load identification module, and an embedded energy management system. The dual-busbar power distribution architecture, the multi-mode seamless switching module, and the load identification module are housed within a distribution box, which is also housed within the integrated wall-type shell. The multi-mode seamless switching module enables uninterrupted voltage waveform switching of the load from the constant power bus to the emergency bus. The load identification module obtains the real-time current waveform of the load through high-frequency sampling and compares it with a built-in feature library to identify the load type. The embedded energy management system receives grid status, battery state of charge, load identification information, and user-preset strategies to execute tiered load control strategies. Compared with existing technologies, this invention offers advantages such as extending the power supply time of critical loads, ensuring stable load operation, and improving system readiness.

The application relates to the technical field of energy storage, and provides a battery cell module and a battery pack. The battery cell module comprises a plurality of battery cells and a special-shaped bus assembly. The plurality of battery cells are arranged in at least two rows and an odd number of columns; two electrodes on each battery cell are arranged at intervals along the column arrangement direction; the plurality of battery cells in the odd number of columns comprise battery cells in a separate column and battery cells in the remaining columns; along the row arrangement direction, the battery cells in the separate column are located at the end of the battery cells in the remaining columns; among the battery cells in the remaining columns, two adjacent battery cells in each row are connected in parallel to form a battery cell group, so that each row comprises a plurality of battery cell groups arranged in layers; and the plurality of battery cell groups in each row are connected in series. At least two battery cells in the separate column are connected in parallel through the special-shaped bus assembly. In this way, the capacity of the battery cell module can be increased without changing the output voltage. When the number of battery cell columns of the battery cell module is odd, at least two battery cells in the separate column can also be connected in parallel, so that the arrangement of the battery cells in the battery cell module is not limited by the number of battery cell columns.

This invention provides a learning machine control method, device, electronic device, and storage medium, relating to the field of control technology. The learning machine control method includes: controlling a distance sensor to start based on a start command from the learning machine; acquiring the distance value between a target object and the learning machine collected by the distance sensor; performing position detection on the target object based on the distance value to obtain a position detection result; if the position detection result indicates that the target object is within a preset range of the learning machine, then controlling the distance sensor to turn off and controlling a temperature sensor to start; acquiring the temperature value of the target object detected by the temperature sensor; performing type identification on the target object based on the temperature value to obtain a type identification result; if the type identification result indicates that the target object is a human body, then controlling the temperature sensor and distance sensor to turn off and controlling a camera to start for posture detection, thereby reducing energy consumption, extending the battery life of the learning machine, reducing the number of charging cycles, and improving the user experience.
