The invention relates to an internet-based distributed type closed-
loop control system and method.
The internet-based distributed type closed-
loop control system mainly comprises a controlled
system, a monitoring unit, a local control calculating unit, a control
execution unit, a local gateway, a communication
server and a
remote control calculating unit, wherein the monitoring unit is used for monitoring a certain variable of the controlled system and transmitting a monitoring value to the local or
remote control calculating unit through the local gateway, wherein the local or
remote control calculating unit is distributed on
the internet; the local or remote control calculating unit is used for comparing the received monitoring value as an input with a target
value set by the system in advance, respectively finishing the respective calculation tasks and generating respective control instructions; and the control instructions generated through calculation are processed according to a certain
logical relationship and then are output to the control
execution unit for executing control on the controlled system.
The internet-based distributed type closed-
loop control system has the following characteristics of good real-time property, high reliability, strong applicability, convenience in implementation, low cost, good expansibility and wide market prospect.
