Problems solved by technology

However, it will cause the "parallel" signal line to be locked, and must be solved by other means. Part of the "parallel" signal lines are not interconnected or short-circuited, which directly leads to the failure of the main-standby switching circuit, and even serious dual-active or dual-standby states.

Embodiment Construction

[0045] 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, door dog 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 method to realize communication device single board, which comprises the following steps: after initiating single board and setting it for prepare status and operating board information through main parts; when there is response, the board part reads board information to fulfill bus read or write operations and signal series and conversion and control module interface; according to the coded board information and main parts, aid parts status information and information interacting. The invention also discloses one communication device single board inverse device.

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, in the communication equipment, the two functional boards configured with 1+1 hot master / standby redundancy are mutual master and backup, 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 following sign...
