An intelligent workshop parallel control method includes the steps of A, constructing a parallel control simulation platform; B, establishing a parallel execution mechanism; and C, performing correction and optimization of a parallel control system. An intelligent workshop parallel control system includes an MES module used for issuing a production instruction to each unit control module; unit control modules used for converting the received production instruction into a machine instruction, then synchronously issuing to bottom layer PLCs through a bus control network module, and driving the parallel control simulation platform and field equipment to move through a soft PLC and a hard PLC; the bus control network module used for establishing a network among the MES module, an SCADA module,an industrial control computer, physical equipment and a whole line simulation model; and the SCADA module used for receiving the field information and motion state of the field equipment and parallel control simulation platform and used for receiving real-time data collected through a sensor.
