Control device for use in a power supplying apparatus including multiple processors adapted to perform separate functions associated with status monitoring and load balancing
First Claim
1. A multi-processor control device adapted for use in a power supplying apparatus that includes a plurality of power supplying units, said multi-processor control device comprising:
- at least two separate processors adapted to be connected to the power supplying units, said processors being adapted to jointly perform separate control functions associated with status monitoring and load balancing control of the power supplying units, said processors being connected to each other and further performing a continuous verification operation, in which signal exchange between said processors is continuously executed to enable each of said processors to verify whether or not other said processors are operating normally, each of said processors being capable of generating a warning signal in the event that any one of said processors fails to respond thereto due to malfunctioning of any one of said processors;
an alarm generator connected to said processors and activated by the warning signal from any of said processors so as to generate a warning output; and
an analog-to-digital converting circuit connected to said processors and adapted to be connected to the power supplying units, said analog-to-digital converting circuit being adapted to convert analog voltage outputs of the power supplying units into corresponding digital signals that are provided to said processors, wherein said processors include a load balancing processor adapted to control the power supplying units so as to balance power load of the power supplying units in accordance with the digital signals received from said analog-to-digital converting circuit.

Abstract
A multi-processor control device is adapted for use in a power supplying apparatus having a plurality of power supplying units, and includes at least two separate processors adapted to be connected to the power supplying units, and an alarm generator connected to the processors. The processors are adapted to jointly perform control functions associated with status monitoring and load balancing control of the power supplying units. The processors are connected to each other and further perform a continuous verification operation, in which signal exchange between the processors is continuously executed to enable each of the processors to verify whether or not other ones of the processors are operating normally. Each of the processors is capable of generating a warning signal in the event that any one of the processors fails to respond thereto due to malfunctioning of the latter. The alarm generator is activated by the warning signal from any of the processors so as to generate a warning output.
