本论文介绍了新型的铁路货车偏载检测系统的设计方案,对测控系统的软硬件做了系统论述,并给出了部分设计框图。该系统可实现车辆偏载状态的检测，且便携、可方便拆卸，实现了装载时对货车偏载情况的在线检测。该系统包括利用超声波测距技术的偏载检测无线发射模块和带有显示提示功能的无线接收模块，二者通过无线射频模块进行数据传送，然后通过数据的显示等得出最终检测结果，从而得知该货车的偏载量是否在正常范围内。-This paper introduces a new set of railway vehicle detection system of partial design of monitoring system hardware and software to do a systematic way, and gives part of the design diagram. The system can detect the state of unbalanced load of vehicles, and portable, can be easily demolished, loaded on trucks to achieve a partial load conditions on line. The system including the use of ultrasonic distance measuring technology, Unbalanced Load Detection with a wireless transmitter module and the display prompts the wireless receiver module, both through wireless RF module for data transmission, and then display the data obtained through the final test results, finally get the partial knowledge of the truck load is within the normal range.
