原来我们使用的有线基带传输多路遥测仪每次使用都需要大量的电统,人力物力花费都很大。后来我们只用了少量的器材,把这套仪器改造为无线传输的多路遥测仪。经多次使用,效果很好。现将改造中用到的部分电路介绍如下: 一、收发转换电路根据原来机器的工作方式,我们选用了民用车载半双工电台。 We use the original wired baseband transmission multiplexer each time you need to use a lot of power system, human and material costs are great. Later, we only used a small amount of equipment to transform this instrument into a multi-channel telemeter for wireless transmission. After repeated use, the effect is very good. Now part of the circuit used in the transformation described below: First, the transceiver circuit According to the original way of working of the machine, we chose the civilian car half-duplex radio.
