ATCA机箱中业务板电源的监测与控制

摘要

The research of power monitoring and control on ATCA boards was focused on, which employed power monitoring chip ispPAC-POWR1220AT8 trom Lattice Ltd. to monitor power states of ATCA boards, and controlled the power enable pins through secondary power module. Power states were collected tor processing by one microprocessor HD64F2167V from Renesas Ltd., and were reported to shelf management controller through the dual redundant IPMB (intelligent platform management bus) buses. Each power states could be monitored remotely through an Ethernet port. The testing results manifest that the system for power monitoring and control has the high reliability.%对ATCA机箱中业务板电源监测与控制进行研究,采用Lattice公司的电源监控芯片ispPAC-POWR1220AT8来控制其电源状态,并通过管理次级电源模块控制板上各个电压.结合Renesas公司的HD64F2167V微处理器,处理收集到的业务板各个电源状态,通过双冗余的IPMB总线反馈给机箱管理控制器.通过以太网接口可远程监测业务板上各路电压状态.实验结果表明:该系统对电源的监控具有较高的可靠性.
