摘要
Dallas公司的单总线技术以其结构简单、造价低廉的特性,非常适合应用于低速的数据采集及传输系统。单总线技术是使用一根数据线与一根返回线实现数据通信的主从式网络。其最大的特点就是在一对双绞线上除了实现数据、地址、控制三种信息流的传输外,还由主机通过这对双绞线集中给各分机馈送电源。这样就避免了复杂的接线方式,特别适合于多点数据采集与监控现场应用。文中主要讨论了利用单总线技术为单线器件提供电源的几种方法。
The single bus with both simple structure and low cost are suitable to low velocity data collection and transmission system.Single bus technology is a master-slave network with data communication by both a data line and a return line.By a pair of twisted pair cable, the power is offered to slave microprocessor from master microprocessor,besides transmission of data,address and control information flow is realized by single bus technology,which is suitable for multi-point collection and on-the-spot supervisory control without complex connection ways.Several methods supplied power by single bus technology are discussed mainly.
