The Columnsyn Sensor Displacement Measure

The Columnsyn Sensor is a new digital type linear displacement sensor. It was carried on analysis the Phase Demodulation mathematics models of the Columnsyn static measure and Columnsyn dynamic measure, that is one of the basic methods of the grid type measure. It applied single chip microcomputer system to digitally process the measure information that obtained from the Columnsyn Sensor. By using a pair of Single Chip Microcomputer system to constitute the double coordinate displacement measure system, so it can strengthen real time performance of the system. It mainly discussed the realization the principle of Phase Demodulation by applying Timer/Counter 8254 and Trigger D. It discussed the data processing principle and processes for the increasing quantity type grid measure, finally.
