摘要: 针对矿用隔爆型线阵列X射线接收箱不适应高带速输送带无损探伤，且对于宽带面输送带无损探伤时存在隔爆外壳加工困难、质量大等问题，设计了一种以FPGA为核心的矿用本质安全型线阵列X射线接收箱。该X射线接收箱由信号探测板及信号处理板组成，信号处理板支持4条总线接入，每条总线最多级联6块信号探测板，每块信号探测板搭载4个X射线探测器，X射线探测器的像元间距为1.6 mm且具备16个探测通道，因此X射线接收箱检测宽度可达2.4 m。信号探测板用于采集经输送带衰减后的X射线信号并转换为线阵列X射线图像数据，信号处理板实现对信号探测板图像数据的同步高速采集和处理，同时采集输送带实时运行速度，并通过千兆以太网接口传输数据。测试结果表明，该X射线接收箱具有质量小、安装方便等特点，满足高带速、宽带面的煤矿钢丝绳芯输送带X射线无损探伤的需求。Abstract: The mine-used explosion-proof line array X-ray receiving box is not suitable for nondestructive testing of high-speed conveyor belts. And there are difficulties in processing the explosion-proof enclosure and heavy weight for nondestructive detection of wide-surface conveyor belts. In this context, a mine-used intrinsically safe line array X-ray receiver box based on FPGA is designed. The X-ray receiving box consists of signal detection board and signal processing board. The signal processing board supports 4 buses. Each bus cascades up to 6 signal detection boards. Each signal detection board is equipped with 4 X-ray detectors. The image spacing of the X-ray detector is 1.6 mm and the detector has 16 detection channels. Hence, the X-ray receiving box has a detection width of 2.4 m. The signal detection board is used to collect the X-ray signal attenuated by the conveyor belt and convert it into line array X-ray image data. The signal processing board realizes the simultaneous high-speed acquisition and processing of the image data of the signal detection board, and also collects the real-time running speed of the conveyor belt and transmits the data through the Gigabit Ethernet interface. The test results show that the X-ray receiving box has the characteristics of light weight and easy installation, and meets the requirement of X-ray nondestructive inspection of coal mine steel cord conveyor belt with high belt speed and wide belt surface.
