Abstract

The invention relates to the technical field of power supply, and discloses a power supply switching control circuit, a power supply control system and method and a readable storage medium. The power supply switching control circuit comprises a first switch module, a second switch module and an equipment switch module, the input end of the first switch module is used for being connected with the power supply end of a battery module, the control end of the first switch module is used for being connected to the first control end of a control module, and the input end of the second switch module is used for being connected to the power supply end of an external power supply module. The output end of the first switch module and the output end of the second switch module are connected to the input end of the equipment switch module, and the output end of the equipment switch module is used for being connected to electric equipment. During a power failure of the external power supply module, when the control module is used for informing the electric equipment to execute power failure emergent processing process and receives the indication that the emergent processing of the electric equipment is completed the equipment switch module is controlled to be switched off, so that the service life of the battery module can be effectively prolonged.

Description

technical field [0001] The present application relates to the technical field of power supply, and in particular to a power supply switching control circuit, a power supply control system, a method, and a readable storage medium. Background technique [0002] When control systems such as communication systems and industrial control systems face sudden power outages, they usually require the system's internal controllers (such as industrial computers, processors) to delay shutdown in order to complete the storage of current operating node information and related operating data, and Shutdown can only be performed after this type of data is sent to the upper control terminal. In this case, a battery-powered system is required inside the system. Due to the poor power supply endurance of the battery, and for the sake of miniaturization, the usual battery capacity is only sufficient for the key control system to run for a few minutes. , it is powered by the battery-powered syste...
