Blade measured data digitalized processing method and device

Abstract

This invention is a digitalization processing method and device for blades detecting data, which structure is composed of blades measuring digital processor (processor for short) and computer. The method uses processor to drive the separate circuit to acquire the digital pipe scanning driven signals of three screw pitch gage digital tables, converting the acquired scanning signals to standard signals sending to sub-circuit of CPU board through signal drive and photoelectric isolation, acquiring sampling signals through the parallel ports, then transmitting these values to the host computer through the communications drive sub-circuit. Advantages: transforming the measured data read by processor into the standard serial communication signals, transmitting to the host computer, realizing Computer Remote Control function.

Description

Technical field: [0001] The invention relates to a digital processing method and device for analog data measured in blade detection. The method and device can be applied to digital processing of analog quantities in various propeller blade detection equipment. It belongs to the field of detection technology. technical background: [0002] In the manufacturing process of the blade, the processing of the blade is a very complicated and important processing technology. The quality of the processing directly affects the performance of the finished blade. During the processing, multiple measurements of the blade data are required. The measurement of the blade data is realized by the blade detection equipment. During the measurement process, it is necessary to manually read and record the data detected by the blade detection equipment. After the detection is completed, all the measured data needs to be analyzed and processed, and the processing results are used To guide the further pro...
