Abstract

The invention provides a multipath incremental encoder signal real-time online fuser which comprises an input preprocessing unit, a CPLD (complex programmable logic device) unit, a DSP (digital signal processor) unit, an output interface unit, a clock generating unit and a system power supply unit. The input preprocessing unit comprises an optical coupling isolation module, a differential to single-ended conversion module and a level matching module. The CPLD unit performs phase discrimination, subdivision, counting and data latching to multi-path single-ended signals. The DSP unit comprises a data fusion processing module and an output interface selecting module. The clock generating unit provides close signals for the CPLD unit and the DSP unit. The system power supply unit powers the units of the fuser. By the multipath incremental encoder signal real-time online fuser, same-dimension multipath incremental encoder signals can be fused into one-path accurate measurement signals which are transmitted to a CNC (computer numerical control) device special a machine tool. The CNC device realizes real-time online information processing and controls related motion parameters, work efficiency of a measurement and control system is increased, and accuracy in measurement information and motion control is increased.

Description

technical field

[0001] The invention relates to a sensor signal processing device, in particular to a real-time online fuser for multi-channel incremental encoder signals. Background technique

[0002] With the continuous development of my country's economy, aviation, aerospace, shipbuilding, turbines, generators and other fields require a large number of large, complex and high-precision parts, which inevitably require related large-scale geometric measurement technology as technical support. At present, there are many large geometric quantities that cannot be measured by existing measuring instruments and technologies. This is because when the size of the workpiece exceeds the measurement range of the instrument, or the hidden point cannot be measured due to visibility restrictions, one instrument often cannot measure all the workpieces. Therefore, the application of multi-sensor information fusion in the field of large-scale measurement has more and more obvious advantage...
