MEASUREMENT DATA COLLECTION SYSTEM

PROBLEM TO BE SOLVED: To provide the measurement data collection system that collects detected data at a low cost. SOLUTION: A D channel packet exchange 4 converts a measurement data transmission request command in compliance with the RS 232C sent from a data processing computer 1 into a D channel packet signal, transmits the converted signal to a D channel packet exchange 5 via a D channel of an ISDN 3, the D channel packet exchange 5 converts the signal into a signal in compliance with the R, S 232C, which is sent to a measurement device 2. The measurement device 2 transmits measurement data in compliance with the RS 232C to the D channel packet exchange 5, which converts the signal into a D channel packet signal and the signal is sent to the D channel packet exchange 4 via the D channel of the ISDN 3 and the D channel packet exchange 4 converts the signal into measurement data in compliance with the RS 232C and the data are sent to the data processing computer 1.
