Abstract


The single- bus technology is today 's hot communication technologies . To solve the problems of communication and power supply through a single cable , has the advantages of simple structure, low cost , saving I / O port resources to facilitate bus expansion and maintenance . Single- bus technology is applicable to a single host control of one or more occasions from machine equipment can be widely applied to the state of the environment monitoring , regulatory and other low-speed residential area the field of measurement and control system . The single - bus technology has two major drawbacks . First , the data transfer rate is lower : the range of applications is limited to a small power terminal equipment . New single- bus communication technologies embodiment limitations of existing single- bus technology development : ary pulse amplitude modulation technology , improve the data transfer rate ; take advantage of the constant current source and high efficiency DC / DC converter as a single the power supply of the bus devices . This paper first argues that the design of new single- bus communication system , designed for new single- bus communication system channel coding . Then, for the design and study of single - bus technology to provide convenient , taking into account factors such as cost of the project and construction difficulty , choose a new single- bus communication system based on transmission line theory , transmission medium , the method of analysis of transmission line losses . Finally, designs and implements a typical new single- bus communication system circuit .
