摘要
耕作机械性能试验过程以单片机为前台机采集数据，用１种专用编码电路携带数据资料经高频载波把编码信号发射到地面站，经相应解码电路可直接得到４位并行数据。
The process of the performance test of tillage machinery was using a single chip computer to collect data and a kind of special coder to carry data through high frequency carrier to transmit coding signals to the ground receiver and then through a corresponding decoder, 4 bits of parallel data could be immediately obtained. From the standard 25 pin connector of printer, PC directly took those data.
