Apparatus for monitoring power supply and method for implementing veneer thermal backup

Abstract

The invention discloses an implementation method for a power monitoring device and the hot backup of a single plate. In the power monitoring device, high-speed data storage and exchange of two control signal plates are realized by a double-port RAM with a double-circuit battery for power supply of a back plate; gating of the control single plates is realized by a simple and reliable arbiter; on a software, the two control plates work simultaneously, exchange data, compare, judge, analyze and detect fault points and guarantee that normal single plates without faults have control right for the system. The invention can realize hot plug; if fault occurs, the single plates can be exchanged without cutting off the power; even, when the control plates have faults or are plugged simultaneously, the control of the monitoring unit to the system can be constant, thus having quite high reliability and maintainability.

Description

technical field [0001] The invention relates to the technical field of power supply, in particular to a power supply monitoring device in communication equipment and a method for realizing single-board hot backup therein. Background technique [0002] With the advancement of science and technology, more and more industrial control, medical, communication, consumer and other electronic products are becoming increasingly intelligent, and embedded systems with microprocessors as the core are increasingly widely used. Especially in the industrial and military fields, in harsh environments and unattended fields, intelligent embedded systems completely replace manual work. However, in these areas, embedded systems need to operate very reliably. Usually, the equipment used will operate 24 hours a day and 365 days a year without stopping, and during this period of operation, no equipment damage can occur, so the high stability it requires is much higher than that required by ordina...
