A digital twin-based near-physical simulation integrated debugging method and system

Abstract

The invention discloses a digital twin-based near-physical simulation integrated debugging method, comprising the following steps: a production line simulation model building step, a twinning step, a system debugging step, a hardware-in-the-loop debugging step, and an equipment-in-the-loop debugging step. Also disclosed is a digital twin-based near-physical simulation integrated debugging system, including a production line simulation model building module, a twinning module, a system debugging module, a hardware-in-the-loop debugging module, and an equipment-in-the-loop debugging module. In the digital twin-based near-physical simulation integrated debugging method and system thereof, since a local component twin is successfully debugged, the local component twin is replaced as a physical component. When a problem occurs after the replacement, only the local component needs to be reset The twin can be debugged and optimized, saving time and reducing costs.

Description

technical field [0001] The invention relates to the technical field of automated production lines, in particular to a digital twin-based near-physical simulation integrated debugging method and system thereof. Background technique [0002] The existing automatic production line and equipment development mode is a serial mode from mechanical design, electrical control design to software verification. In the serial development mode, design problems at all levels will only be gradually exposed in the integration debugging stage, and even cause some system-level problems, resulting in the functional integrity, control logic accuracy, and performance reliability of automation equipment failing to meet production requirements , making the performance of the production line system degrade. The current production line debugging method is to put the whole system into the production of physical equipment after the system simulation debugging is completely successful, but the disadvan...

AI Technical Summary

Problems solved by technology

In the serial development mode, design problems at all levels will only be gradually exposed in the integration debugging stage, and even cause some system-level problems, resulting in the functional integrity, control logic accuracy, and performance reliability of automation equipment failing to meet production requirements , which reduces the performance of the production line system

The current production line debugging method is to put the whole system into the production of physical equipment after the system simulation debugging is completely successful, but the disadvantage of this method is that the production of physical equipment must be started after the debugging is completed, and then the entire virtual and physical equipment will be realized. Replacement, if there is a problem after the replacement, the virtual part must be debugged again, and then the physical device should be improved again, thus prolonging the development cycle and increasing the cost
