The invention provides a power supply switching system and method, electrical equipment, a vehicle accident alarm method and a computer storage medium. The method can temporarily and quickly switch toa standby power supply to supply power when a main power supply is powered down, then further judges whether the operation of switching the standby power supply to supply power is necessary or not, if yes, maintains the standby power supply to supply power, and if not, terminates use of the standby power supply. Therefore, the standby power supply can be switched in time under the condition thatthe main power supply is powered down, some unnecessary standby power supply switching conditions can be avoided, and electric power waste of the standby power supply is avoided.
本发明提供一种电源切换系统、方法及电气设备、车辆事故报警方法和计算机存储介质,能够在主电源掉电时,临时且快速地切换成备用电源供电,之后能进一步地判断切换备用电源供电的操作是否是必须的,若是,维持备用电源供电,若否,终止备用电源的使用,由此不仅能够在主电源掉电的情况下及时切换备用电源,还能够避免一些不必要的备用电源切换情况,以避免备用电源的电力浪费。
