Embodiment Construction
[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0030] Since the power supply units configured inside the existing main chassis are two redundant power supply units, the air-cooling fans are three, such as figure 2 As shown, the four-way voltage outputs of the two power supply units are all connected to the input of the power supply of the backplane, and the backplane outputs the backplane power supply signal to the DC control protection platform chassis monitoring control device (hereinafter referred to as the monitoring control circuit) provided by the present invention. and backplane bus information, and correspondingly output control signals to the backplane bus; each power supply unit can output two signals to the monitoring control circuit, one signal AC_OK indicating the AC power failure of the power supply unit, and the other is the internal working status of the power supply unit The signal DC_OK...

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.
Description
technical field [0001] The invention relates to a DC control and protection platform chassis monitoring and control device. Background technique [0002] The DC control and protection platform host is the core equipment of the DC control and protection system. The mainframe of the DC control and protection platform is generally a plug-in design and a box-type rack structure. In addition to the processor, communication and I / O and other functional plug-ins in the box, the box itself is also equipped with a bus backplane, power supply and instructions. and other basic support components. The basic support part is the basis and premise of the reliable operation of the chassis. Once a failure occurs, it will cause the failure or shutdown of the main engine and affect the reliable operation of the entire control and protection system. Therefore, the monitoring and control of the basic auxiliary systems in the chassis are also very important. Specifically, on the one hand, the c...
