<p>PROBLEM TO BE SOLVED: To reliably acquire data which occurs at a predetermined time interval without being dependent on communication performance via the Internet with unstable communication performance. SOLUTION: In a data acquiring method, after logging in from a client to a server (step 101), 3 basic processing steps of establishing a fixed interval in a step 102, acquiring a data file (step 104) and measuring processing times (step 106) are looped. In the processing, the number of missing files used at a branch 204 is computed at a branch 201 in a step 103 and a judgment whether re-acquiring of processing in a step 105 should be performed or not is made at a branch 202. From a result of the step 106, a judgment whether an additional acquiring processing should be performed or not is made at branches 203, 204.</p> |
