摘要
远动通道测试意义重大,数字远动通道与模拟远动通道不同,传输的信息是二进制数字码流。文章通过对PCM数字接口传输远动信号的基本原理进行分析,找出对数字远动通道的测试就是RS-232简易接口的测试,从而有针对性的提出几种简单、实用的测试数字远动通道的方法。这些测试方法所需的条件不同,应根据实际情况和具备的条件选用,从而在投资很少的情况下,可以快速、简捷的测试出数字远动通道的好坏。
Telecontrol channel examine method is of consequence. Compared with analog telecontrol channel,communication transmitting in digital telecontrol channel is binary digit code. In this article through analyzing the keystone of PCM digital interface transmitting telecontrol signal, then find out that digital telecontrol channel online test is RS-232 simple interface test. Thus tabling some simple and useful method of digital telecontrol channel online test. Those methods need different conditions, as we could choose right method in right circumstance. Hence we can fleetly and succinctly test quality of digital telecontrol channel in low-invest.
