Embodiment Construction

[0016] Referring to Figure 1, the digital processing device for blade measurement data is composed of a blade measurement digital processor and a computer (existing technology); the input end of the blade measurement digital processor is connected to the digital tube scanning of the blade detection equipment The signal output terminal, the communication signal output terminal of the blade measurement digital processor is connected to the RS-232 serial input terminal of the computer. A signal driver can be connected in series between the blade measurement digital processor and the computer to realize long-distance transmission.

[0017] The digital display in the blade inspection equipment is used to measure the three data of the blade surface radius, pitch, and angle at each measurement point of the blade. It uses the blade measurement digital processor to convert the three data of blade surface radius, pitch, and angle at each measurement point of the blade, and the converted dat...

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...
