DBS分布式控制系统(以下简称DBS系统)是机电部六所结合国内工业控制的实际需要而开发的新产品。DBS系统采用了BITBUS的互联规范,解决了一点对多点的远程通讯问题,又利用STDBUS的外围接口模板品种齐全,方便灵活的优势,大大地提高了系统的控制能力及整体可靠性。 DBS系统采用主、从结构,命令/响应式控制方式,网络拓扑为总线式,传输介质采用普通的双绞线,电气标准采用RS-485规范,使用SDLC链路协议,结构参见图1。 DBS系统可靠性高,价格低廉,功能完善,支持软件丰富,适用于各
The DBS distributed control system (hereinafter referred to as DBS system) is a new product developed by the Electrical and Mechanical Services Department in line with the actual needs of domestic industrial control. DBS system uses the interconnection specification of BITBUS, solves the problem of remote communication of point to multipoint, and utilizes the advantages of STDBUS peripheral interface template to provide complete and convenient, flexible and greatly improve the control ability and overall reliability of the system. The DBS system adopts the master and slave structure, command / response control mode, the network topology is a bus type, the transmission medium adopts ordinary twisted pair, the electrical standard adopts the RS-485 standard and uses the SDLC link protocol, and the structure is shown in FIG. DBS system, high reliability, low price, full-featured, rich software support for each
