Complete machine power P of frame type communication equipmentGeneral assemblyIs the output power P of a single power supplyOutput ofProduct of the number of power supplies N: pGeneral assembly＝POutput of*N
Total power loss P of frame communication deviceConsumption unitAs loss P of a single power supplyUnit consumptionProduct of the number of power supplies N: pConsumption unit＝PUnit consumption*N
Loss of a single power supply PUnit consumptionIs a power input PInput deviceProduct with power loss efficiency (1-E): pUnit consumption＝PInput device*(1-E)
Through the formulas, the complete machine loss power P of the frame type communication equipment can be obtainedGeneral assemblyFunctional relationship with power supply efficiency E:
at the power P of the whole machineGeneral assemblyUnder certain circumstances, PConsumption unitInversely proportional to the power efficiency E, the greater E the PConsumption unitThe smaller. Therefore, under the condition that the power of the whole machine is constant, the working efficiency of a single power supply is improved by reducing the number of the working power supplies, so that the power loss of the whole machine is reduced, and the effect of saving energy is achieved.
In the application, the main control board of the frame-type communication device executes the power management task and calculates the output power and the whole power of each power supply according to the power management cycle polling.
