The topology structure of the field bus is discussed, the principle of communication by using it is analyzed on the basis of Profibus-DP, the mode of communication and link is explained in detail, and the field bus network for controlling master-slave motor is built up based on PLC.
The automation of a substation is a integrated technology of microcomputer, micro-electronics, modern communications and auto-control technique, which realizes not only the full-scale rebuilding of relaying but also the mode of communication for the traditional substation.
This paper analyses the applications, the fundamental strength and weakness of TDM and PDM respectively, pointing out that PDM, as a different mode of communication, will be a strong competitor to TDM.
The model study of novel IED based on new substation communication network and standard IEC61850 is presented, compared with existing device of traditional substation automation system. The working mechanisms of IED are analyzed on the architecture of IEC61850, logical model, data object model, and the performance and mode of communication network. The designs of function model, information flows and classes of IED of transformer differential protection are given,the testing simulation indicates the advantages of the IED design.
Inthis paper, it has detail discussed the working principle of DGPS, the mode of position,the mode of communication, the cause of system error and key arithmetic of dataprocess, present the correlative arithmetic and program source code.
Besides researched the system framework of the Fiscal Horizontal Online Networking System, we researched some key technologies like middle operation platform, the middle ware of TUXEDO, the mode of communication, the accessing of share memory, the message format, the parsing of the message and beforehand derive sub process and so on.
This paper elaborates the realization meaning,guiding principle, function and composition of pharos remote sensing and control stystem, which adopts complex mode of communication function and data storage structure in the light of the characteristics of pharos remote sensing and control The trial operation effect of this system has been proved satisfactory
The upgrading of communication network brough about radical changes in the mode of communication,made the comunication management highly efficient and very smart,and greatly improved the quality of communication.
Multicast is rapidly becoming an important mode of communication and a good platform for building group-oriented services.
The present study examines the ways in which one aspect of language use, namely figurative language, differs as a function of mode of communication.
Variations in Figurative Language Use as a Function of Mode of Communication
Thus, the study showed that emotion-related information can be encoded in the quality of hand movements during signing and that this information can be decoded without previous experience with this particular mode of communication.
Demographic characteristics and the youth's degree of hearing loss and mode of communication were used as control variables.
