| Zusammenfassung: | The invention provides a PLC power control device and method, and relates to the technical field of power management, the device comprises a CPU module, a power failure maintaining and discharging module, a power failure detection module and a power supply module, the power supply module is used for supplying power to the power failure maintaining and discharging module and the power failure detection module, and the power supply module is used for supplying power to the power failure maintaining and discharging module and the power failure detection module. The power failure detection module is used for detecting whether the power supply module is powered down; when the power supply module does not have power failure, the power failure maintaining and discharging module is charged through the power supply module and stores electric quantity, and the power failure maintaining and discharging module supplies power to the CPU module; and when the power supply module is powered down, the power-down maintaining a |
