摘要
在地震前兆仪器金属水平摆JB仪和石英摆SQ仪中使用的配套电源由于记录图纸型号的变更而满足不了仪器的正常记录,原来配备的配套电源对于记录使用的灯泡在断丝情况下也没有报警信号,影响了仪器数据的记录质量。为了解决上述问题,我们对金属水平摆JB仪和石英摆SQ仪使用的配套电源进行重新研制。文章介绍了新配套电源的基本构成,硬件组成,时钟芯片SD2405AP的使用方法。新配套电源采用AT89C2051单片机控制电路,单片机控制逻辑程序的编程。电源还提供了记录灯泡电压的断丝报警。
The recorder paper size of the tilt-meters, type JB and SQ, changes very often in seismic station of Panzhihua and so the requirement for the power supply has to be changed accordingly in order not to affect operation of other instrument normally. In this paper the hardware, such as clocking chip SD2405, Single-Chip control board are listed. The circuit outline and the control program for single-chip board at the same time is presented. The effect of using this device in the Seismic Station of Panzhihua is good.
