Abstract: A digital twin-based edge-end collaborative scheduling method for heterogeneous tasks and resources includes the following steps: establishing an edge wireless network based on digital twin; constructing an edge-end collaborative scheduling problem prototype of the heterogeneous tasks and resources; performing problem conversion based on a multi-agent Markov decision process; constructing an Actor-Critic neural network model based on multi-agent deep reinforcement learning; performing offline centralized training of the neural network model by digital twin; performing online distributed execution of task offloading and computation and communication resource allocation by end devices to collaboratively process the heterogeneous tasks. The method optimizes the heterogeneous computation resource types, the task offloading ratio, the transmit power of the end devices and the computation resource allocation ratio of edge servers through digital twin, supports the on-demand offloading of heterogeneous tasks, realizes edge-end collaborative computing, and minimizes the total task processing delay.

Abstract: The present invention relates to a network guard unit for an industrial embedded system and a guard method. The specific method is to form the network guard unit (NGU) through security technologies, such as integrated access control, identity authentication and communication data encryption, to provide active guard for a site control device. The NGU comprises an access control module, an identity authentication module, a data encryption module, a key negotiation module and a PCIE communication module, and supports the communication modes of dual network cards and PCIE bus. The present invention builds a secure and trusted operating environment for industrial control systems in combination with an active guard technical means in the field of information security on the basis of ensuring the correctness and the feasibility of security of various terminal devices in the industrial control systems.
