The SCDMA base station construction mainly includes two stages: the hardware installment stage, the transmission channel opening stage.

Testing and Assessment Platform of Railway Section Signal Systems --study on modelling and simulation of the information transmission channel;

The article introduces the consist of remote-supervision, image and network structure mode of control signal for transmission channel of sub-station, and analysises the function and mode to achieve remotesupervision system for sub-station in detail.

An IP-based method for supervising the electric power telecontrol transmission channel is discussed and a network-level supervising mode with both points and lines is presented, especially the channel-level supervising method based on source routing of IP protocols.

This paper precisely introduces the basic theory of Fibre Liquid-lever Meter, puts forward that the computer program can serve as data-delivering channel from Fibre Liquid-level Meter to configuration software, and simply analyses the realization of computer program and main code in the program.
