多处理机的分布式控制比较经济,外围设备少,所以获得了广泛的应用。多处理机的连接方式如图1所示,它有下列优点;1.能改善控制功能;2.提高了可靠性;3.提高了互换性;4.改善了数据的存贮和显示;一、分布式控制系统的结构主要包括微处理机控制器,通信系统,数据显示器。下面就有关哈耐威尔(H0neywell)公司研制的分布式控制系统(TDCS2000)的功能和结构进行说明。基本功能是调节过程(稳定),一次报警并能控制
Multiprocessor distributed control more economical, less peripheral equipment, so access to a wide range of applications. Multiprocessor connection as shown in Figure 1, which has the following advantages; 1. To improve control functions; 2. To improve the reliability; 3. To improve the interchangeability; 4. To improve the data storage and display; First, the structure of distributed control system includes microprocessor controller, communication system, data display. The following is a description of the function and structure of Distributed Control System (TDCS2000) developed by HONEYWELL. The basic function is to adjust the process (stable), an alarm and can control
