Signal synchronization circuit and device for data acquisition of optical coordinate measurement system

Abstract

The invention discloses a signal synchronization circuit and device for data acquisition of an optical coordinate measurement system. The signal synchronization circuit comprises a photoelectric coupling module and a differential signal circuit, wherein the input end of the photoelectric coupling module receives a signal source; the photoelectric coupling module processes the signal source to obtain a controller pulse signal and a sensor pulse signal; the first output end of the photoelectric coupling module sends a controller pulse signal to a multi-axis controller; the second output end of the photoelectric coupling module sends a sensor pulse signal to the differential signal circuit; the differential signal circuit processes the sensor pulse signal to obtain a sensor differential signal and sends the sensor differential signal to an optical probe sensor. Visibly, the synchronism of the data acquired by the multi-axis controller and the optical probe sensor is realized, so that themeasurement result can be synchronously latched, the phenomenon that the acquired data is asynchronous is prevented, and the precision of an optical coordinate measurement system is improved.
