Embodiment Construction

[0022] Such as figure 1 , figure 2 , image 3 As shown, a program-controlled switch power management unit includes a chassis 1, a DC PDU power distribution unit 2, a heat dissipation unit 3, and a monitoring host 4. The DC PDU power distribution unit 2 is set in the chassis 1, and the heat dissipation unit 3 is set on the chassis 1. The DC PDU power distribution unit 2 includes an input terminal 21, an output terminal 22, and a rectifier 23. The input terminal 21 includes a main power supply 24 and a backup power supply 25. The main power supply 24 and the backup power supply 25 are both -48V DC power supplies. Both the power supply 24 and the backup power supply 25 are connected to the rectifier 23 for switching between the main power supply 24 and the backup power supply 25, the output 22 is connected to the rectifier 23, and the monitoring host 4 is connected to the DC PDU power distribution unit 2 for real-time monitoring of the chassis 1 The internal temperature of the in...

Abstract

A stored program control exchange power supply management unit of the present invention comprises a chassis, a DC power distribution unit (PDU), a radiating unit and a monitoring host. The DC PDU is arranged inside the chassis, the radiating unit is arranged on the chassis, and the DC PDU comprises an input end, an output end and a rectifier. The input end comprises a master power supply and a standby power supply which are both connected with the rectifier to switch the master power supply and the standby power supply, the output end is connected with the rectifier, and the monitoring host is connected with the DC PDU. The advantages of the present invention are that: the master power supply and the standby power supply are arranged and distributed by the rectifier and are inputted to the equipment by the output end, thereby guaranteeing the situations that one of the master power supply and the standby power supply can supply power to the equipment effectively on the condition that the other one of the master power supply and the standby power supply is interrupted, and a stored program control exchange operates stably, and preventing the service interruption.

Description

Technical field [0001] The invention relates to a power management unit of a program-controlled exchange. Background technique [0002] At present, program-controlled switches carry a wide variety of services and have extremely large operating power. To ensure their continuous and safe operation, multi-power protection should be deployed for them. However, existing program-controlled switches do not have a power management unit that supports multiple power inputs, and program-controlled switches have power supplies. The major defect without effective protection has caused the program-controlled switch to not be able to operate continuously and safely. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a power management unit of a program-controlled switch, which solves the problem that the existing program-controlled switch has no effective power protection. [0004] In order to solve the above technical problems, the present...
