摘　　要：提出一种基于两总线方式的工业多路测量控制系统。系统由８０９８单片机、编码电路、解码电路、电流功率驱动电路和Ｖ／Ｆ转换电路组成；可测量１０２４路模拟量或开关量，输出１０２４×３位开关控制量，测控范围１～６００ｍ。所有的传感器和控制单元均以两线方式并接在系统的两总线上，系统体积小，结构简单，且具有较强的可靠性及抗干扰性能。A control system that is based on double bus mode and can be used for industrialmultiplex measurement is intreduced.The system consists of a single chip processor 8098,encoding and decoding circuits,power current driving circuit and V/F transducer.It canmeasure 1024 tracks of analog or switching variables. The range of measurement and control is 1￣600m.All the sensors or control units are in parallel connection with the system bus. It is ofsimple construction,small overall dimension, and high reliablility and noise resisting ability.
