Method and system for constructing digital twin of cooking target linked with kitchen appliance

A digital twin system, comprising:

• a transceiver capable of transmitting and receiving information to and from a customer terminal, a kitchen appliance, and a machine learning module through a network;
• a memory storing an application for receiving target condition cooking data from the kitchen appliance and receiving input data from the machine learning module to form a digital twin for a cooking target;
• a processor for reading and controlling the application from the memory;
• an input unit for receiving instructions from a user through the customer terminal;
• and
• an output unit for outputting a result value under the control of the processor,
• wherein the application enables the digital twin system to receive target cooking condition data and real-time cooking target data from the kitchen appliance, enables the digital twin system to materialize a digital twin simulation based on the received target cooking condition data and real-time cooking target data, enables the digital twin system to receive input data required for a heat transfer simulation from the machine learning module, and enables the digital twin system to estimate an internal temperature value for monitoring a cooking process of the cooking target in real time.
