本装置可以用无线电传送启爆指令、启爆后的时间(即爆炸信号)和τ值(即井口检波器信号)。使用本仪器可以省去铺设仪器至井口检波器的电缆,从而能节省人力,提高工效。本仪器在正确的操作之下,τ值准确清晰,遥控系统安全可靠,并可消除炮盒,自动放炮线和τ值线漏电等原因所造成的各种信号感应和不启爆,误爆等现象。现将该仪器简单介绍于下。构造及方框图基本原理仪器部分由884型电台(单功),发射附加器,接收附加器,收发转换器,信号分离器,电
The device can transmit the blast command by radio, the time after explosion (ie explosion signal) and the value of τ (ie, the well head detector signal). Use this instrument can save the laying of the instrument to the wellhead detector cable, which can save manpower and improve work efficiency. The instrument under the correct operation, accurate and clear value of τ, the remote control system is safe and reliable, and can eliminate the gun box, automatic gun line and leakage caused by a variety of reasons such as signal leakage and unexplosive, misdetection, etc. phenomenon. Now the instrument is briefly introduced below. Structure and Block Diagram Fundamentals The instrumentation consists of Type 884 radio (single power), transmitter adder, receiver adder, transponder, demultiplexer, power splitter
