Design and Performance Analysis of X-ray Photoelectric Collector for Logistics Transportation

Abstract

The strong conveyor belt has been widely used in mines, ports, wharves, power plants, steel mills, and other fields. It is one of the main transportation equipment in modern production. In coal mine production, the logistics conveyor belt is essential equipment. The increased load can scratch and age the conveyor belt. Then, coupled with the elongation of joints, the equipment fails. This work designs an X-ray Photoelectric (XP) collector for logistics transportation and puts forward the design scheme. This work expounds on the hardware circuit of the XP collector, mainly based on the Image Capture Card (ICC) of the S8865 module and the serial/parallel data acquisition board based on the AD7667 chip. In the test, the Field Programmable Gate Array (FPGA) development tool ISE of Xilinx company is used to design the software of the XP collector to collect logistics X-ray signals. The oscilloscope analyzes the ICC control signal RESET, which repeatedly appears in a certain period. The S8865 module is controlled to collect X-ray signals continuously; the analog output signal of the S8865 module is observed. Under the control of a 1 MHz clock, the S8865 module outputs a stable analog signal. Similarly, observing the differential signal output of the differential processing circuit on the ICC through the oscilloscope finds that the differential signal is consistent with the original signal. Further positive input/output of the signal conditioning circuit of the serial/parallel data acquisition board is observed after the differential signal is switched. The single-ended signal after switching is consistent with the differential signal’s positive input signal.
