REMOTE SUPERVISORY SYSTEM OF SHIELD APPARATUS

摘要

PROBLEM TO BE SOLVED: To transfer the data of the site to a remote place to enable remote supervision even when a data management personal computer in the site goes down. SOLUTION: The operation data of a shield apparatus comprising a shield machine 110 and a segment assembling device is taken in a data management personal computer 210 through sequencers 200X, 200Y and 200Z. The taken operation data is stored in a hard disc 220 and a communication control substrate 230. The communication control substrate 230 transmits the stored operation data to a remote supervisory personal computer 250 through a public circuit 244 at a designated time.
