数据传输是实现载波通信网集中监控的关键。通过它把主控站的监控命令传送给被控站和把被控站采集的数据传送给主控站,才能集中监视通信网中各站、各设备的工作状况。本文主要讨论载波通信网集中监控系统中数据传输分系统的构成,数据电路的连接方式,调制解调器的调制方式,通信接口与调制解调器的连接,差错控制方式和通信控制规程等几个主要问题;最后简要说明通信软件及其流程图。
Data transmission is the key to realize centralized monitoring of carrier communication network. Through it to the master station control commands sent to the accused station and the accused station collection of data sent to the master station in order to focus on monitoring the communication network of the station, the working conditions of the equipment. This article mainly discusses several major issues such as the composition of data transmission subsystem, data circuit connection mode, modem modulation mode, communication interface and modem connection, error control mode and communication control procedure in the centralized monitoring system of carrier communication network; Describe the communication software and its flow chart.
