摘　　要：提出了对地震台BHC-336定标器电源改进方案,研制地震前兆仪器多路隔离直流电源及实时监控系统,介绍了本系统的电源结构设计、硬件设计实现和软件的设计实现。在盘锦地震台进行了应用测试,通过应用多路隔离直流电源前后FD-125测氡仪主样、副样的差值和误差率的变化趋势直观说明了系统的实用效果。This paper puts forward to a proposal for the improvement of the power supply to the BHC-336 calibrator used for seismic stations, devises a multi-way isolation power supply and a real-time monitoring system used for earthquake precursor observation devices, and introduces how to materialize this system＇s power supply structure design and hardware design. Tests have been conducted for the application of this system at Panjin Earthquake Station, and its practical results are indicated visually from the trends of changes in the difference between original samples and duplicate samples and its error rates.
