Problems solved by technology

After the power switching is completed, the single-board system needs to perform service switching, switching the single-board business from the backup single board back to single-board A101. When the system main control unit detects that the single-board A101 can work normally, A service switching signal is issued, and the business is realized by the cooperation of the single board A101 and the single board B102 again. This business switching process will also have an instantaneous impact on the business

Abstract

The key ideal of the invention is: setting a power detecting circuit, control circuit and a switching circuit in a communication single-chip without a native power supply; the power detecting circuit is used in detecting a power supplying signal and outputting a power detecting signal to the control circuit; the control circuit is used in comparing the power detecting signals from power detecting circuit with a service switching signals from outside, and outputting a control signal to the switch circuit to make power switch.

Description

technical field [0001] The invention relates to the communication field, in particular to a communication single board, a system and a power supply switching method for matching use. Background technique [0002] In the design of communication products, it is very common for communication boards to be used together. For example, there are two boards used together in a product. In some cases, due to the relatively high integration level of one of the boards, it is impossible to set the power supply in a limited area of ​​the board, so another board with power supply can only be used for the high power supply through the connector on the motherboard. Integrated single-board power supply, at the same time, in order to ensure the uninterrupted power supply of the communication system and further improve the reliability of the power supply, it is necessary to introduce another backup power supply to supply power to the single board. [0003] Referring to FIG. 1, FIG. 1 is a stru...
