【発明の名称】複数点同時計測システム
Document Type and Number:
Japanese Patent JP2553688
Kind Code:
B2
Abstract:
PURPOSE:To transmit the measured values from plural measuring instruments in time division by providing an arithmetic control part which outputs the measured value based on a transmission time difference and a synchronizing signal. CONSTITUTION:The system is comprised of a displacement measuring instrument 31 with transmitter, a synchronizing signal output part 32, and a host system 33 which receives the measured value from the displacement measuring instrument 31 with transmitter and performs a data processing. The transmission time difference is set so as to evade the coincidence of mutual measured value transmission time at the transmission time difference setting part of the measuring instrument 31 with transmitter setting the synchronizing signal from the synchronizing signal output part 32 as reference, and the arithmetic control part 28 outputs the measured value inputted from a measuring part to a transmission part 30 with a cycle decided based on the synchronizing signal and the transmission time difference. The host system 33 receives the measured value sent from each displacement measuring instrument 31 with transmitter by attaching time difference on each value, and performs a prescribed data processing. In such a way, a large number of measured values can be transmitted with a single frequency band area by setting an output interval to output each measured value.
