| Abstract: | In order to enhance the level and accuracy of automation for wet coke quenching control,the control system based on programmable logic controller (PLC) has been designed. The system is composed of Siemens S7-200 PLC as the slave computer; through MPI communication protocol,communications connection with the monitoring host computer is established to implement wholly automatic control and real-time monitoring for the wet coke quenching process. The system enhances the quality of the technological process and... |
