PID温度控制器是一种能够将需要控制的温度，通过温度传感器对温度进行检测，把检测到的温度转换为电信号，然后把这个检测的信号与控制温度的信号进行比较，根据比较的结果来判断是不是已经达到了所设定的温度目标。如果还没有达到所要求的温度，就需要根据这两者之间的差值再进行调整，一直达到所设定的温度要求为止。

今天，这篇文章来讲讲dcs分散式控制系统的结构。

DCS分散式控制系统，由分散在系统中不同节点的处理器组成，高可靠性是其基本特性。

DCS分散式控制系统由两个最基本的环节组成：DCS级和控制管理级。

相对于中央式控制系统，分散式的系统可以缓解单一处理器造成的失效。在分散式控制系统中，如果有某一处理器失效，它影响的只是生产流程中的一部分，而在中央式控制系统中，如果某一处理器失效，整个系统都会受到影响。

此外，由于DCS分散式控制系统的控制器与现场的输入/输出设备距离较近，也能减少网络ot中央处理的延时，控制器处理速度可因此提升。

PID temperature controller is a temperature that needs to be controlled, the temperature is detected by the temperature sensor, the detected temperature is converted into an electrical signal, and then the detected signal is compared with the control temperature signal, according to the comparison results to determine whether it has reached the set temperature target. If the required temperature has not been reached, it needs to be adjusted according to the difference between the two, until the set temperature requirements are reached.

Today, this article will talk about the structure of dcs distributed control system.

DCS Distributed control system is composed of processors scattered in different nodes in the system, and high reliability is its basic characteristic.

DCS Distributed control system consists of two basic components: DCS level and control management level.

Compared to a centralized control system, a decentralized system can mitigate the failure caused by a single processor. In a decentralized control system, if one processor fails, it affects only one part of the production process, whereas in a centralized control system, if one processor fails, the entire system is affected.

In addition, because the controller of the DCS distributed control system is closer to the input/output device in the field, the delay of network ot central processing can also be reduced, and the controller processing speed can be improved.
