Design And Implementation Of Power Intelligent Management For TD-LTE Wireless Base Station

With the continuous development of 4G TD-LTE in China,the number of TD-LTE base stations has exceeded 1.65 million.As TD-LTE has a broad market prospects,with the development of technology,TD-LTE base station miniaturization will become a trend,the future of TD-LTE will have a fast and independent networking,low cost,light weight,small size Features,but also stable and reliable work.The power supply unit inside the base station has put forward higher requirements.Finally,this paper proposes a scheme to add an intelligent management module to the power supply unit.Through the study of domestic and foreign manufacturers launched by the power products found that the existing products more are just to achieve the Internet access,or more are simple monitor the hardware parameters,and the command is not compatible.The intelligent management module is designed on the basis of the IPMI specification.The power management module can support up to 9 output power on / off functions,with FRU,SDR,Event,Double power supply and Hot Swap and so on.As a result of the use of standard IPMI standard protocol,users can directly use IPMITOOL,GNU Free IPMI,OpenIPMI and other free IPMI system management tools,when you monitor and manage the power unit.The power management module designed in this paper is more intelligent and more common than the existing power management module.Power intelligent management module using LPC2468 and EP1C12 hardware architecture to achieve,the circuit can be divided into processor module,control module and monitoring module from the implementation function.The processor module is the core of the intelligent management module.The processor module realizes the function of hardware control and hardware health information collection through the control module and the monitoring module respectively.The software has two major components,installed in LPC2468 and EP1C12 respectively.They implement IPMI communication protocol,power supply management,Hot Swap state management,FRU and Sensor information management,power output control,and output power voltage monitoring.The test shows that: power intelligent management module has been achieved 9 channel power control,has been achieved by the FRU,SDR and EVENT mechanism to obtain the hardware information,sensor management and alarm functions,has been achieved hot-swappable and dual power supply function.Indicating that the management module has the advantages of intelligent and control the versatility.
