Remote operation system and measurement system

A remote operation system that enables remote operation of an electronic appliance, which is capable of executing a process set in advance in keeping with control data from an external apparatus and outputting response data relating to the process set in advance to the external apparatus, via the Internet by an operation terminal as the external apparatus that is capable of accessing arbitrary resources connected to the Internet, the remote operation system comprising:

• a first processor connected to the Internet;
• and
• a second processor that is locally connected to the electronic appliance and set up so as to be capable of access by the first processor via the Internet,
• wherein the second processor executes a first process that establishes a first communication path that enables reception of transmission data via the Internet from the first processor at any time, and
• the first processor executes a second process that instructs the second processor via the first communication path to establish a second communication path for performing end-to-end communication between the electronic appliance and the operation terminal to enable remote operation of the electronic appliance by the operation terminal via the Internet.
