| 摘 要： | ５７００系统的数据是用曼彻斯特码传送的；信号传输利用了电缆缆芯间的不同组合，形成了信息号传输的三种方式：方式２、方式５、方式７。传送的信号有指令信号和数据信息两种。选用不同的传输方式，传输的一帧字的位数也不同。在整个系统建立时，对同一仪器串、相同的地面设备、因电缆不同，所选用的通讯参数也不同。

| Abstract: | Manchester code is used for data transmission in 5700 System, which utilizes different combinations of wireline conductors to form three transmission modes (Mode 2,Mode 5 and Mode 7) for commands and data transmission. The number of bits transmitted in a frame is different for different transmission modes. Due to different cable, communication parameters selected are different for the same tool string and the same surface equipment when the system communication is being set up. |
