A working method of industrial Internet system architecture based on standard communication protocol includes the following steps:
(1) an industrial internet architecture is constructed that includes a plurality of nodes, each node communicatively coupled to at least one other node via a standard communication protocol.
(2) A user accesses the node to which the user belongs by adopting a web browser through Ethernet line connection through a client, and the node to which the client belongs operates a web server.

(4-1) establishing a connection; establishing a secure connection; the secure connection process is part of the standard communication protocol. Various security mechanisms may be employed in the connection process for a communication protocol. For example, using a public/private key mechanism, the connection requesting party encrypts the connection request packet with the public key of the other party (the requested party). After receiving the request packet, the opposite party (the requested party) decrypts the request packet by using the private key of the opposite party, then places the session key in the response packet, encrypts the session key by using the public key of the requesting party and sends the encrypted session key to the requesting party. The requesting party decrypts the message by using the private key of the requesting party to obtain the session key. So that both parties share a session key known only to them. The next data interaction is encrypted and decrypted by the session key.
(4-2) data interaction;
(4-2-1) data request: the node needs to send a data request to another node which is connected according to a standard communication protocol; if the request is successful, the data of the requested node is sent to the requesting node; if the request is not successful, the requesting node cannot obtain the data of the requested node.

(4-2-3) end of transmission: when the data transmission requested by the requesting node is finished, the requested node stops the data transmission with the requesting node.
(4-3) connection termination; under normal conditions, after the transmission is finished, the connection between the requesting node and the requested node is automatically terminated according to a protocol, which may be a special instruction packet exchanged after the data packet is finished, or a termination command implied by the last data packet. If the termination is abnormal, after a party (the requesting node or the requested node) does not receive a signal of the other party (the requested node or the requesting node) for a period of time, the termination is defaulted, and some corresponding good postprocessing is carried out.
(5) And (4) calculating by the data calculation module according to the data obtained in the step (4), feeding back a calculation result to a user, and storing the data to a database module of the node for later use.
