| description | A polymerization kettle valve control system based on a DCS comprises at least three detection modules, a logic operation module and a switch control module, and the detection modules are distributed at the top, the middle and the bottom of a polymerization kettle; the detection module comprises a sensor and a signal judging device. The sensor collects data and generates a monitoring value. The signal judging device is connected with the sensor, obtains a monitoring value and converts the monitoring value into a judging signal; the logical operation module is respectively connected with each detection module and is used for respectively receiving the judgment signals generated by each detection module, carrying out logical judgment on each judgment signal and generating a control instruction; the switch control module is connected with the logic operation module and used for receiving the control instruction and executing the instruction to control the valve. DCS distributed management is adopted, so that the |
