The invention relates to a direct current control protection platform case monitoring and control device. The direct current control protection platform case monitoring and control device comprises a signal logic control module and a state output module; the signal logic control module is provided with a power source signal input end, a power source control signal output end, a backplane signal input end, a backplane control signal output end, an over-voltage and under-voltage protection signal input end and a fan signal input end; the logic control module includes a redundant power source electrification and de-electrification management logic unit, an over-voltage and under-voltage protection control logic unit, a fan protection control logic unit and a state output logic unit, wherein the state output logic unit is used for performing state judgment according to redundant power source information, backplane bus information and fan rotation speed information and outputting state judgment information through the state output module. With the direct current control protection platform case monitoring and control device adopted, safety detection can be performed on a case comprehensively, and the situation of case operation faults which is caused by the missing of one part of fault detection can be prevented, and damage to the case and other equipment can be further prevented.
