Digital twin intelligent edge terminal and operation method therefor

A digital twin intelligent edge terminal interacting with a cloud digital twin system, comprising:

• a state perception module physically connecting the digital twin intelligent edge terminal to the cloud digital twin system and single or multiple application objects and external sensors via various data interfaces so as to acquire perception information and upload the perception information to the cloud digital twin system for application;
• a decision reception and execution module configured to receive a decision instruction on the cloud and executing the decision instruction on the edge side, and select, according to whether a control system configured to control application objects has an instruction interface and a transmission protocol, a working mode to perform a dispatch of decision information;
• a human-computer interaction module configured to configure basic information of the digital twin intelligent edge terminal, connection parameters between the digital twin intelligent edge terminal and the control system/external sensors/cloud digital twin system, a data structure of the cloud digital twin system, set personnel permissions, receive and display the decision instruction and operation and maintenance information of the decision reception and execution module, and display the decision instruction and the operation and maintenance information according to the personnel permissions;
• a digital twin local control module configured to interact with the cloud digital twin system or collaborate with the state perception module, the decision reception and execution module, and the human-computer interaction module in different working modes;
• a functional module manager configured to drive the state perception module, the decision reception and execution module, the human-computer interaction module and the digital twin local control module, and implement information interaction between the modules;
• wherein the decision reception and execution module is further configured to:
• when the control system for a current application object has an instruction interface and a transmission protocol, receive the decision information dispatched by the cloud digital twin system, and parsing the decision information to obtain a portion of the decision information that belongs to the current application object;
• translate, according to an instruction structure of the control system, the portion of the decision information, that belongs to the current application object, into operation instructions of the control system so as to cause the control system to control the current application object;
• control the current application object based on the operation instructions;
• when the control system for the current application object does not have an instruction interface and a transmission protocol, receive the decision information dispatched by the cloud digital twin system, and parse the decision information to obtain a portion of the decision information that belongs to the current application object;
• output the portion of the decision information, that belongs to the current application object, to the human-computer interaction module for display so as to enable operation and maintenance personnel to operate according to prompts;
• and
• display the portion of the decision information.
