Abstract: A fire extinguishing control method, a fire extinguishing system, and a storage medium are provided. The fire extinguishing protection system includes a fire extinguishing system and a device to be protected. The fire extinguishing system (3) is configured to extinguish a fire in the device to be protected (2). The fire extinguishing system includes a fire extinguishing apparatus. The fire extinguishing control method is applied to the fire extinguishing system. Flame feature data of at least one preset portion of the device to be protected is obtained. A processing mode of the fire extinguishing apparatus is determined according to the flame feature data of the at least one preset portion in the case that presence of a flame is determined according to the flame feature data of the at least one preset portion. The fire extinguishing apparatus is controlled to perform a corresponding operation according to the determined processing mode.

Abstract: A power-off protection apparatus and a power-off protection system are provided. The power-off protection apparatus is applied to the power-off protection system. The power-off protection system includes a laser machining device and a power control device. The power-off protection apparatus, the laser machining device, and the power control device are in communication connection. The laser machining device is powered on by the power control device. The power-off protection apparatus is configured to send a final encoded power-off signal to the power control device, to cause the power control device to perform a power-off operation to power off the laser machining device.
