Tricon控制系统的主要特点 Tricon是一种高容错的可编程和过程控制技术。 其特点如下: A.提供三模冗余结构(TMR ),具有三个相同的子电路，每个子电路执行独立程度的控制。还有-一个专用的硬件/软件架构，用于对输入和输出进行“表决”能够忍受恶劣的工业环境。 C.它可以在现场安装，并且可以在不干扰现场布线的情况下在现场在线安装和修复模块级。 D.支持多达118个I/O模块(模拟和数字)和可选通信模块。通信模块可以连接到Modbus主机和从属设备，或连接到Foxboro和Honeywell分布式控制系统(DCS), 对等网络中的其他Tricons,以及TCP/IP网络中的外部主机。 E.可以支持距离大型机远1 2公里的远程I/O模块。 F.使用基于Windows NT系统的编程软件开发和调试控制程序。 G.输入和输出模块中的智能功能可减少主处理器的工作负荷。每个I/O模块有三个微处理器。输入模块的微处理器过滤和修复输入，并诊断模块上的硬件故障。输出模块微处理器为输出数据的表决提供信息，通过输出端的反馈回路电压检查输出状态的有效性,并能诊断场线问题。 H.提供全面的在线诊断和修复能力。 I. Tricon启动和运行时， 可以进行日常维护，而不会中断控制过程。 .为/O模块提供“热备用”支持，可用于某些无法及时提供服务的紧急情况。 4118sis Safety Instrumented System Tricon Controller is a fault-tolerant controller based on TMR structure. The fault-tolerant control system can identify and compensate for faults in control system components, and allow for repair of faulty components while continuing to complete specified tasks without interrupting process control. 41 1 8 means that the Tricon control system can repair system faults without affecting normal production. It has the following characteristics: The high safety of 4118 depends on the self diagnosis and online maintenance of TMR hardware structure, 4118 High Availability - Eliminating Misparking, 4118 High maintenance online replacement of faulty cards without the need for parking and maintenance operations without training. Characteristics of Tricon Triple Structure 1. No single point of failure The 4118sis safety instrument system - Tricon controller adopts isolation technology: the three E circuits inside each channel are independent; Three action main processor; Each component box is equipped with dual redundant power supplies (redundant power supplies with evenly distributed loads); Within the 1/0 component, there are no shared components: the channels are completely isolated (which can avoid problems caused by grounding of on-site instruments); Isolation between the system and the site (to avoid the entire system failure caused by strong electrical breakdown of a single module).
