Embodiment Construction

[0048] The technical scheme of the present invention is to change the "parallel" signal interconnection used by the active-standby switching of the traditional single board into I 2 The C bus serial signals communicate with each other, and the active / standby switching control module of the single board detects the I 2 C bus data. When the master / standby switching device of the single board passes the slave device from the I 2 The C bus receives the switching command or status query sent to the bus by the main device of the board, and combines the current board CPU general control signal, watchdog signal, manual button reset signal, manual button switching signal, etc. Standby switchover logical operation, determine the future active and standby state of the board, or report the state of the board to the opposite board. When receiving the active / standby switching command requesting the board to be upgraded from the standby, the operation of upgrading the board to the active s...

Abstract

This invention discloses one communication device signal board main prepare inversion device, which comprises main prepare inverse control module and bus, wherein, the main prepare inverse control module is to receive input signals to fulfill single board main prepare inverse control; bus interface unit connected to the bus, wherein, the bus interface unit is to receive series signals into parallel signals to main prepare inversion module; the said bus interface unit si to convert received parallel signals into series signals to bus.

Description

technical field [0001] The invention relates to a 1+1 thermal active / standby configuration technology for functional single boards in communication equipment, and specifically relates to a communication equipment single board active / standby switchover device and an implementation method. Background technique [0002] Usually, the two functional boards in the 1+1 hot master / standby redundancy configuration in the communication equipment are mutual masters and backups, and the two boards are connected through several hardware direct connection signals on the backplane, and the boards use These signals are used for active / standby control and switching, including the active / standby status output signal of each board, the active / standby status input signal of the opposite board, the online output signal of each single board, the online input signal of the opposite board, the reset signal of each single board, and the heartbeat signal Wait, there are also plans to use the followin...
