The structure of remote power-supply system,the hardware design scheme and software strategy on power-management of the power-distribution manager were presented.
介绍了基于网络线的远程供电技术及该技术在现代网络通讯设备应用中的现状和前景,提出了一种兼容性高、模块化的监控模块的设计方案。
According to the temporary technical specifications of the DC remote supply system of PAS cell station by Chinese telecommunication group,the key technical problems that are the DC-DC power,the multiplex unit,the protection of the touched power line and AC-DC conversion circuit when the multiplex ISDN signal line transmits the electricity.
描述了小灵通基站电源存在的问题及业界的一般解决方案,并结合《中国电信集团公司小灵通基站直流远供系统技术规范》(暂行)的要求,指明了复用ISDN信号线路进行电力传输时需要解决的关键技术难点:DC-DC电源、复用单元、电力线碰触防护、交直流电源切换单元。
The monitor unit is the control core of the PAS remote supply power system.
为了保证小灵通基站电源的可靠性,业界提出了通过ISDN通信线路进行信号和电源同时传输的方案,即直流电源远供;由于监控单元是小灵通远供电源系统的控制核心,因此,监控模块能够稳定和可靠地工作是保证远供电源系统可靠运行的关键;而通信局站中通信设备众多,电磁环境相对比较恶劣,因此对设备的电磁兼容性要求也较高;分析了小灵通基站电源监控模块的功能与结构,并从原理图设计、PCB设计及外壳设计方面给出了解决电磁干扰的方案;实践证明,该监控系统运行稳定可靠,取得了预期效果,具有较高的实用价值。
