Abstract: A method and a system of industrial data communication with dedicated physical isolation are provided that, the data collector and the physical isolator cooperate with each other. The data collector collects the data of each nodes of an enterprise by the intranet or by the wired and wireless communication module. The data is converted into encrypted messages under a protocol. The physical isolator secondarily encrypts the data and uploads the standardized data to a cloud platform via the internet. The data is exchanged between the data collector and the physical isolator by a dedicated data channel. The data transmitted in the dedicated data channel is encrypted by an algorithm, and is transmitted in a form of encrypted messages. Two ports of the dedicated data channel can only transmit the data in the form of encrypted messages. The dedicated data channel uses specific communication media, and forms physical isolation directly.
