Telecommunication monoboard and system kit and power-supply switching method

Abstract

The invention discloses a communication single board without a self-contained power supply, a communication single board system for supporting use and a power switching method thereof. The core of the present invention is to set a power supply detection circuit, a control circuit and a switching circuit in a communication single board without its own power supply. The power detection circuit is used to detect the power supply signal of the board, and output the power detection signal to the control circuit; the control circuit is used to compare the power detection signal received from the power detection circuit with the service switching signal received from the outside , and output a control signal according to the comparison result to control the switching circuit to switch the power supply. The single board, the system and the power switching method disclosed in the present invention can make the service switching and the power switching overlap in time, and the instantaneous influence of the power switching on the service is merged into the service switching process, thereby avoiding the inconsistency between the power switching and the service switching. The secondary impact of simultaneity on veneer business.

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] see figure 1 , figure 1 It is a str...

AI Technical Summary

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
