Based on the above analysis results , the system design is finished . the system design principal is detailed . the system architecture and data transmission proctocal are discussed . in order to transmit multi - channel data simutaneously on the monacable , tdm ( time division multiplexing ) technique is adoped in the system design . a special code is designed for data transmission on the tool - bus , so that the too - bus can both supply power and transmit data 包括单芯电缆数据传输系统的设计思想、结构设计和数据传输协议的制定。在单芯电缆数据传输系统设计中，采用时分多路复用技术，实现多种参数仪器数据的同时传输。在仪器总线上采用特殊的码进行数据传输，使得仪器总线既能供电又能传输数据。
