ARIES交叉站传输电路工作原理及故障维修

The working principle of ARIES cross station's transmission circuit and its maintenance methods

交叉站的传输部分是交叉站中重要的组成部分,它的主要作用是将来自仪器车的查询命令传输给采集站并将来自采集站的数据和状态返回给仪器车。本文主要介绍了ARIES交叉站传输电路的信号流程和工作原理;以及ARIES交叉站的测试步骤、测试仪传输测试的测试原理和测试结果显示;最后还介绍了ARIES交叉站常见传输故障的维修方法。

Transmission circuit is the most important part of cross station, which plays the role to send commands from the instrument to the acquisition station and return the data and status from the acquisition station to the instru- ment. This paper mainly introduces the signals process and the working principle of ARIES cross station＇s transmis- sion circuit. Finally, the repair method of common transmission fault of ARIES cross station is also introduced.
