Short Content: 0 forewords: Redundant type UPS is also called redundant type UPS and machine the system, its characteristic is and machine at the same time supplies power by two or two above UPS to the load, in capacity at least redundancy UPS. The redundant type UPS reliability is high, when or redundancy several UPS presents the breakdown, other UPS still might to the load power supply, avoid because of presenting breakdown UPS normally, but power failure. In redundant type UPS and ...

Short Content:     Abstract: Elaborated the excess afterheat backup battery's principle of work and the design proposal.     Key word: Is stirring up the converter; Excess afterheat backup; Or gate diode Introduction When designs some redundant reliable computer system, requests its necessary power source to adopt the redundancy design. Generally speaking, may adopt the plan has the capacity redundancy, the redundancy cold backup way, the parallel even class N 1 backup way, the excess afterheat backup way. The capacity redundancy is beacons ...

Short Content:   An introduction< ?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />     In order to guarantee that data in computer system in transmission and memory correct reliable, has introduced the channel coding. Has two aspects regarding the channel coding; first, after request code symbol stream frequency spectrum adaptation channel frequency characteristic; second, examines error code which and corrects produces. The former belongs to the spectrum forming technique, the latter for error control technology. The CRC code belongs to the latter. ...
