Directing against the most important condition for establishing the remote diagnosis centre—the requirement of remote data transmission

a remote data transmission network based on three layer structure of Internet has been designed and developed

it features distinct structure

liable to maintain

little amount of encoding work

and easy to realize reusing the programme stage. Practice shows that the said transmission network can fully satisfy the requirements of remote diagnosis

even though being separated by more than thousand kilometers

the sampling cycle only being （27）s

having strong realtime property and high reliability

as well as bright future of application in engineering.
