DCM-1型数字地磁脉动观测系统,是为开展地磁测深及地磁脉动观测工作而研制的。该系统由高灵敏度磁通门磁力仪、多路数据采集器、盒式磁带记录与回放器,以及时间服务装置等部分组成。系统具有大动态、低噪声、高精度、低功耗,以及操作简单、使用方便等特点。系统可直接与计算机接口,也可直接回放进行模拟恢复。利用该系统进行了多次野外观测,取得了较好的野外观测资料,并显示出比进口的模拟系统能记录到较为丰富的信息。
DCM-1 digital geomagnetic pulsation observation system is developed for geomagnetic sounding and geomagnetic pulsation observation. The system consists of high-sensitivity fluxgate magnetometer, multi-channel data acquisition, cassette recording and playback, and time service devices and other components. System has a large dynamic, low noise, high precision, low power consumption, as well as simple, easy to use and so on. System can be directly interfaced with the computer, but also direct playback simulation recovery. The system has been used for many field observations and good field observation data have been obtained. It shows that more information can be recorded than the imported simulation system.
