今年在本刊第二期上发表了《地震载波仪试制成功》一文,就地震信号载波传输仪的研制、技术指标和试验情况作了简单介绍。这台仪器是四川石油管理局地调处与西南石油学院、四川大学共同研制的。本文着重介绍地震信号载波传输的基本原理及其试验效果。地震信号载波传输的基本原理地震信号载波传输,简称“地震载波”。它应用无线电载波通讯原理,将地震检波器接收到的地震信号荷载在高频振荡上,经传输线输入到载波解调器,由解调器从高频
This year in the second issue of the publication of “Earthquake Carrier trial success,” a article on the seismic signal carrier transmission instrument development, technical indicators and test conditions made a brief introduction. This instrument is the Sichuan Petroleum Administration to adjust the Office of Southwest Petroleum Institute, Sichuan University jointly developed. This article focuses on the basic principles of seismic signal carrier transmission and its test results. Seismic signal carrier transmission principle Seismic signal carrier transmission, referred to as “seismic carrier.” It uses the principle of radio carrier communication, the seismic signal received by the geophone load on the high-frequency oscillation, the transmission line input to the carrier demodulator, the demodulator from high-frequency
