[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a system for automatically switching over failures of master-slave management modules, and another purpose is to provide a method for realizing automatic switching of master-slave management modules for failures. One of the management modules fails and cannot automatically switch to another management module. The abnormal monitoring of the master-slave management module is realized by a third-party CPLD. The CPLD controls the electronic switch and switches the management signal link of the management system of the intelligent cabinet to the master. management module, or from the management module

Embodiment Construction
[0027] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0028] The technical terms involved in the present invention are explained as follows:
[0029]
[0030]
[0031] The present invention provides a system for automatic switchover of master-slave management modules, the schematic diagram of which is as follows figure 1 As shown, the system includes a management subsystem for monitoring the cabinet. The management subsystem includes a main management module and a slave management module. The monitoring signals of the master management module and the slave management module are respectively sent to the CPLD chip. The main management module It is connected with the slave management module through the UART serial port for real-time synchronization of the data set by the master management module and the slave management module; the master management module transmits sign...

The invention relates to a cabinet management system and an implementation method thereof, in particular to a system for automatically switching master-slave management modules in failure and an implementation method thereof. The abnormal monitoring of the master-slave management module is realized by a third-party CPLD. The CPLD controls the electronic switch to switch the management signal link of the management system of the intelligent cabinet to the master management module or the slave management module. The invention solves the problem that one of the master-slave management modules fails and cannot automatically switch to another management module. The master-slave management module is monitored by a third-party CPLD, and the electronic switch is controlled by the CPLD, which has the characteristics of simple algorithm and high reliability. .
Description
technical field [0001] The invention relates to a cabinet management system and an implementation method thereof, in particular to a system and an implementation method for automatic switchover of a master-slave management module upon failure. Background technique [0002] The management system of the intelligent cabinet has functions such as intelligent monitoring and management of the temperature of each slot in the cabinet, power on and off, power consumption, and fan speed. The core of the management system is the management module, which requires the management module to be highly reliable and have redundant modules. After the main management module fails abnormally, within the specified time range, the signal link of the management system of the intelligent cabinet is switched to from the management module. [0003] At present, the main management module actively sends monitoring signals to the slave management module. When the monitoring signal is abnormal, the manag...
