数据传输技术在电力系统远动、自动化系统中得到了广泛的应用。随着计算机技术、CRT远传、继电保护以及监控系统和现代科学管理的发展,数据传输技术将得到更广泛的发展。 由于数据传输技术发展的阶段性,直到目前为止,还不能普遍采用数字信道来传输数据。仍然利用原有的质量良好的模拟信道实现数据传输。为了实现这种传输,在数据终端设备与模拟信道之间,必须装设接口设备——调制解调器。这种调制解调器不仅具备接口功
Data transmission technology has been widely used in power system remote and automation systems. With the development of computer technology, CRT remote transmission, relay protection and monitoring system and modern scientific management, data transmission technology will be more widely developed. Due to the stage of data transmission technology development, until now, digital channels have not been widely used to transmit data. Still use the original good quality analog channel to achieve data transmission. In order to realize this kind of transmission, must install the interface device - modem between data terminal equipment and analogue channel. This modem not only has interface skills
