一、工业控制计算机的特点工业控制计算机是用于过程测量,过程控制及监督管理的计算机。由于它要适应各种控制对象的要求,因而与一般的通用计算机有许多不同之处,它有以下几个特点: 1.可靠性要求高:工业控制机通常用于控制连续的生产过程,且在生产期间一般不允许停机检修。一旦计算机发生故障将会引起质量事故,甚至生产事故。因而它应具有高可靠性和安全性。必须采用一系列的安全措施以确保平均故障间隔时间MTBF达到几千到几万小时,要求故障修复时间短,运行效率高。 2.实时响应性好:因为工控机对生产过程进行实时控制,因而要求它即时响应控制对象各种参数的变化,抓住控制时机进行控制,所以它必须具有实时时
First, the characteristics of industrial control computer Industrial control computer is used for process measurement, process control and supervision and management of the computer. Because it has to adapt to a variety of control object requirements, and general general purpose computer has many differences, it has the following features: 1. High reliability requirements: Industrial control machine is usually used to control the continuous production process, and In the production of the general does not allow downtime maintenance. Once the computer fails will cause quality accidents, and even produce accidents. Therefore, it should have high reliability and safety. A series of safety measures must be taken to ensure that the mean time between failure MTBF reaches thousands to tens of thousands of hours, requiring a short time to repair the fault and high operating efficiency. 2 real-time response is good: Because the IPC for real-time control of the production process, requiring it to respond immediately to changes in various parameters of the control object, control the timing to seize control, so it must have real-time
