地下水水位动态作为地震的一种前兆观测方法,已引起国内外地震工作者的广泛重视。国内业已布设了大量水位观测井网,进行大范围的水位观测。但迄今,水位观测仍是分散的、单井孔的,其数据尚不能向中心传输,更不能自动输入计算机进行处理。 SSC-1型水位数字传输系统系采用微计算机技术进行远程数字传输的设备。该系统采用PCM-ASK-FM/TDMA制式对水位变化进行无线,有线以及混合信道传输,亦
As a kind of precursory observation method of earthquake, the dynamic of groundwater level has aroused widespread attention of earthquake workers at home and abroad. The country has laid a large number of water level observation well, a wide range of water level observations. However, up to now, the water level observation is still scattered. For single well, the data can not be transmitted to the center and can not be automatically input into the computer for processing. SSC-1 water level digital transmission system is the use of micro-computer technology for remote digital transmission equipment. The system uses PCM-ASK-FM / TDMA standard for water level changes in wireless, wired and mixed channel transmission, also
