Abstract：In order to realize group control of tyre capsule vulcanizer，a master-slave control system was composed of industry computer and programmable logic controller（PLC）. The industry computer was taken as host computer. WebAccess configuration software was applied as development platform. The industry computer can realize dynamic display of data，storage，query，statistics，reports and other functions. PLC was adopted as slave machine to control vulcanizer. The communication of industry computer and PLC was realized through serial port. The temperature of vulcanizer was controlled with fuzzy control strategy. And the fuzzy control strategy was given. The test results indicate that the group control system has friendly interface and operates conveniently. Compared with single control system，the system can improve the capsule quality，production efficiency and level of automation.
