| Summary: | Aiming at the shortcomings of the existing monitoring methods for mechanical wear, a design is proposed in this paper for oil wear particles online monitoring system based on optical method, which can realize the detection for internal wear of gear box or hydraulic equipment under the complex environments, improve detecting ranges of the wear particles and reduce the cost of on-line wear monitoring. A design for image acquisition processor is proposed to realize the acquisition, processing and transmission for HD plane array camera images. The hardware circuit of the image acquisition processor is designed based on the Freescale I.MX6Q. In the embedded Linux environment, the software of the image acquisition processor is designed based on OpenCV to realize the processing of the images captured by the plane array camera. Experiments show that the image acquisition processor can realize functions of on-line wear particles image acquisition, processing and wireless transmission, and can be used for oil detection, fault prediction and diagnosis in bad working environments.
