Design and Application of Two-Dimensional Multi-Channel Automated Testing Platform
Abstract At present, partial detection experiment of scientific research laboratory mainly based on manual, there are some problems of low efficiency, low accuracy of test results and failure rate high. Therefore, we designed a two-dimensional multi-channel automated testing platform for the low speed and light load of the experimental instrument. First, according to the testing function planning platform, and the required components of the test platform for analysis and research, select the appropriate experimental components that meet the requirements of the high accuracy and the stability of the two-dimensional testing platform, including the cross worktable, stepper motor, stepper motor drive, motion control card and switching power supply. Secondly, the human-computer interaction interface is developed by using Basic Visual software, which is convenient for the user to set up according to their own needs. Then, the control program of the test platform is developed to control the movement direction and displacement, so as to realize automatic detection. The displacement accuracy of the detection platform is detected, and the displacement error is less than 20%. Finally, the design of two-dimensional detection platform and Raman spectrometer are combined, and the detection process is introduced.

1 引言 1.1 研究背景 随着科技的快速发展，自动检测技术逐步发展并运用于各个领域。自动检测是指利用计算机控制对部件、设备和系统进行性能检测、故障诊断、连续监测和故障定位 [1]。二维位移平台作为精密仪器的关键部件，在医疗器械、扫描电子显微镜和微电子技术的载物平台方面有较多的应用。将自动检测技术与二维位移平台结合形成二维自动化检测平台，实现自动检测技术在高精定位领域的应用，使二维自动化多通道检测平台具有精度高、检测效率高、检测结果准确率高等特点。它能够替代人工检测，缩短产品的生产周期，为企业节省大量的成本和时间。性能优良的二维自动化检测平台在各个行业都具有良好的应用前景，在替换模具和检测探头后，可以满足各类相关产品的检测需求[2]。 目前，实验室里的部分检测实验以人工操作为主，例如利用拉曼光谱仪进行的检测实验。实验人员在操作过程中存在着定位精度低，遗漏检测点，或者重复检测等问题，对实验结果的准确性造成很大的影响。实验仪器的检测平台相当于二维位移平台，使用二维自动化检测平台取代实验仪器的检测平台，既能提高实验检测结果的准确性，又能为实验人员减少工作量。
