The invention is suitable for the technical field of digital signal processing, and relates to a system and a method for switching and off-line wakeup of double backup power supplies. Comprising a power supply monitoring unit, a super capacitor switching control unit, a central processing unit, a super capacitor power supply, a controllable voltage stabilization unit, a battery power supply, a battery switching logic unit, an offline wake-up control unit and a battery switching control unit. The power supply monitoring unit, the central processing unit and the super capacitor power supply are respectively connected with the super capacitor switching control unit, and the power supply monitoring unit, the controllable voltage stabilization unit, the central processing unit, the battery switching control unit and the offline wake-up control unit are respectively connected with the battery switching logic unit. The super capacitor switching control unit and the battery power supply are respectively connected with the controllable voltage stabilizing unit, and the battery power supply is also connected with the battery switching control unit. According to the invention, the switching control of the double backup power supplies of the super capacitor and the battery is realized, and the off-line wake-up function is realized.
Description
technical field [0001] The invention belongs to the technical field of digital signal processing, and in particular relates to a system and method for dual backup power switching and offline wake-up. Background technique [0002] With the application of the big data concept in the power grid, the power grid data management platform has increasingly strengthened the requirements for the reliability of the collection terminal, especially for the communication function of the collection terminal. In the technical specifications of the power collection terminal, it is clearly required that the power consumption The acquisition terminal needs to continue to work for no less than three minutes when the mains power is off, and has the ability to communicate with the main station at least three times. At the same time, the backup power supply of the terminal is required to ensure reliable operation for at least eight years. [0003] Aiming at high technical specifications, the exist...
