Parallel control method and system for intelligent workshop

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 MES module and a lower-level control network, and constructing a parallel control simulation platform equivalent to the workshop site;
• step B:
• establishing a parallel execution mechanism:
• based on the digital twin technology, establishing a 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.
