Oil is one of the essential components to maintain the proper operation of a twisted pair copper wire. To diagnose whether oil leaking from the wire, it is crucial to detect the oil level in the insulator in the twisted pair copper wire. In this paper, we propose a Wireless Neural Network (WNN) based electro-optic power sensor monitoring system for detecting the oil level in the insulator in the twisted pair copper wire. The proposed system consists of a wireless ultrasonic transmitter for sending the ultrasonic signals to the insulator in the twisted pair copper wire so that the oil level can be monitored by the receiver part, based on a wireless neural network (WNN) techniques. We used the hardware Monte Carlo techniques to investigate the accuracy of the proposed system and find out the best oil level to be monitored in the insulator in the twisted pair copper wire. Finally, we evaluate the hardware and software design and implementation.
In this study, a walking sound inspection apparatus written in OpenCV based on DAQ and microcontroller was designed to evaluate the inspection quality of metallic pipes. A DAQ-usb-max232C interface was applied to the DAQ in the system in order to collect data from the system. A simple control loop system was set up to collect and process data from the system, which was included in the series of operations of a pipe. The system process the data that is collected after the pipe walking procedure was over, then wait if there is any data needed for the pipe inspection. And finally, the data was process based on the evaluation result of the inspection result. All steps of the system design and implementation are discussed in the paper.
In many industries, it often been generally accepted that chemical noise is one of the main obstacles preventing the accurate localization of fatigue cracks in the form of ultrasonic waves, which then obscure the actual crack in the inspection process. However, our previous reports have shown that by exploiting the non-linear properties of the structure prior to inspection, it is possible to generate harmonic components in the spectrum of the convolution of the induced signals at the fundamental frequency and its second harmonic. This technique is known as non-linear ultrasonic modulation (NLUM). d2c66b5586
