MFT—PT型遥测仪的研制,是为了在较大范围内(100—200公里)同时传输观测短周期、长周期地震信号和其他地球物理量. 该仪器系统是由脉冲幅度调制和频率调制两种遥测系统复合组成的.其设计特点有如等待式多相多谐振荡器,单管单稳电路等.遥测仪与电子计算机,磁带机配用可以达到快速综合处理地震信号的目的. 该仪器如果采用话音频率,则可以利用电话线路把地震信号送到几千公里之外.遥测仪如果与射频收发讯机配合,则可以构成无线流动台网.
The MFT-PT telemetry was developed to simultaneously transmit short-period, long-period seismic signals and other geophysical quantities over a large area (100-200 km) .The instrument system consists of two types of pulse amplitude modulation and frequency modulation Telemetry system composite composed of its design features such as waiting for multiphase multivibrator, single-tube monostable circuit, etc. Telemeter and computer, tape drive equipped with a comprehensive and rapid processing of seismic signals can achieve the purpose of the instrument if used The voice frequency, you can use the telephone lines to send seismic signals thousands of kilometers away.Yes telemetry and RF transceiver with the radio, you can form a wireless mobile network.
