MULTIPOINT SWITCH MEASURING SYSTEM FOR CARLSON-TYPE INSTRUMENT

摘要

PROBLEM TO BE SOLVED: To provide the multipoint switch measuring system of a Carlson-type instrument, which guarantees measurement on a subsequent Carlson-type instrument even if a fault occurs in a preceding device. ;SOLUTION: The multipoint switch measuring devices 10(10₁-10_n) corresponding to respective instrument groups 2(2₁-2_k) are installed. The respective devices 10 have multipoint switches 13(13₁-13_k) which sequentially switch/connect the plural Carlson-type instruments 1(1_1i-1_ki) in the same groups with multipont switch control signals to measurement lines LA and LB, measurement parts 8(8₁-8_k) measuring voltage on the respective Carlson-type instruments 1 which are electrically connected through swatches 13 and communication control parts 9(9₁-9_k) transmitting the control signals to the measurement parts 8 and transmitting measured data from the measurement parts 8 on an optical cable OL. A measurement management electronic computer 5 for executing measurement starting and the collection processing of measurement data and a communication control part 12 transmitting the measurement control signal on the optical cable OL by means of a measurement starting command from the computer 5 and taking in measurement data transmitted from respective civil engineering structures are provided on a measurement centralized control place.;COPYRIGHT: (C)1997,JPO
