Title:
REMOTE SYSTEM AND REMOTE CONNECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/249435
Kind Code:
A1
Abstract:
This remote system is such that a server device and a local area network having a production device and a gateway device are connected through a wide area network. The remote system is provided with network equipment for allowing connection from the inside of the local area network to the outside and rejecting connection from the outside to the inside. The gateway device requests the server device for the establishment of a first session with the server device. The server device has an equipment management unit and a connection control unit. The equipment management unit checks equipment identification information, which identifies a target production device designated from an external terminal, against equipment identification information set in the production device. The connection control unit establishes the first session upon receiving the request for establishment of the first session, and when the equipment identification information for the target production device matches the equipment identification information set in the production device as a result of the check performed by the equipment management unit, establishes a second session with the external terminal and connects the first session and the second session.
