摘要
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。
In order to guarantee that the PAS cell station power is reliable, the experts in the field propose that the signal and the power transmit simultaneously through the signal line of ISDN, which is called DC remote supply. The monitor unit is the control core of the PAS remote supply power system. Therefore, the monitor module which can work stably is important for the remote supply power system. But the communication facilities are numerous in the communication station and the electromagnetic environment is relatively quite bad, EMC is demanded highly. The paper analyzes that the function and the structure of the monitor module of the PAS cell station power. It also gives the solution of electromagnetic interference on the aspects of the design of the principle picture, the design of PCB and the design of the shell of the monitor module. The practice verifies that this system runs stably and accurately with expected effects.
