| Abstract: | 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. |
