1. A parallel control method for an intelligent workshop, comprising the following steps:step A: constructing a parallel control simulation platform: performing accurate digital modeling on a real workshop site by third-party simulation software, performing secondary development, performing motion planning of the model and corresponding action control scripts, constructing a downlink instruction channel and an uplink information channel, establishing, by means of an industrial control network, a communication mechanism for a soft PLC and a hard PLC and an asynchronous periodicity synchronization guarantee mechanism for the soft PLC and the hard PLC to realize communication and integration with an upper-level IVIES module and a lower-level control network, and constructing the parallel control simulation platform equivalent to the workshop site;
step B: establishing a parallel execution mechanism: based on a digital twin technology, establishing the parallel execution mechanism for action synchronization of a workshop device model and physical objects thereof;
realizing a communication channel among a soft PLC of a workshop digital model, a PLC of a physical workshop device and configuration software to realize interconnection and intercommunication of data and information, so that a stand-alone physical device can realize action synchronization with a stand-alone digital model corresponding to the whole line on the parallel control simulation platform; and
step C: correcting and optimizing the parallel control system: by the parallel control system, performing simulated launch and simulated production of orders, performing full-view and cross-granularity monitoring of a workshop operation process, performing management of various production operation indexes and response processing of emergencies during an execution process, and performing performance analysis and execution optimization of devices.
