一种接触网限位止钉余量状态检测系统A contact network limit stop nail surplus state detection system

技术领域Technical Field

本发明涉及接触网限位止钉余量状态检测技术领域,具体为一种接触网限位止钉余量状态检测系统。The invention relates to the technical field of contact network limit stop nail surplus state detection, and in particular to a contact network limit stop nail surplus state detection system.

背景技术Background Art

接触网是高速铁路供电系统中的重要设备,具有结构复杂、露天设置等特性,一旦出现问题,极有可能影响整条铁路的供电系统与行驶列车的安全。其中接触网悬挂状态检测监测系统(4C)通过对铁路接触网部件进行高精度成像,以期能及时排除故障隐患,保证部件的良好运行。The overhead contact network is an important equipment in the power supply system of high-speed railways. It has the characteristics of complex structure and open-air setting. Once a problem occurs, it is very likely to affect the power supply system of the entire railway and the safety of the running trains. The overhead contact network suspension status detection and monitoring system (4C) can eliminate potential faults in time and ensure the good operation of the components by performing high-precision imaging of the railway overhead contact network components.

限位定位器限位止钉余量是接触网零部件中的一个重要参数,采用限位定位器时,定位器与止钉应具有适宜的余量。但由于长期的日晒雨淋、机械应力、强电磁场甚至涉及火车行驶产生的震动等原因,止钉极易出现螺丝松动的状况,导致余量产生变化,严重时甚至会影响列车的正常运营造成事故。The margin of the limit stopper of the limit locator is an important parameter in the contact network components. When the limit locator is used, the locator and the stopper should have an appropriate margin. However, due to long-term sun and rain, mechanical stress, strong electromagnetic fields and even vibrations caused by train running, the stopper is very likely to loosen the screws, resulting in changes in the margin, which may even affect the normal operation of the train and cause accidents in serious cases.

现有的对接触网限位定位器限位止钉余量状态进行分析的方法,主要采用人工定期巡检与技术人员查看4C接触网高精度图像相结合。前者劳动强度大,工作周期长,也不容易发现缺陷。而对于后者,虽然很大程度上减少了排查工作量,但技术人员仍要从巨量的接触网高精度图像数据中找到限位定位器,再对限位止钉的余量状态进行分析判断,耗时耗力,且极易因视觉疲劳而导致漏检的发生。因此,设计面向接触网高精度图像的,能自动化、智能化的检测监测各种故障的系统便成了需要面对的问题。设计一种智能化检测限位定位器止钉余量状态的系统对于保障接触网安全运行有着极为重要的现实意义。The existing method for analyzing the residual state of the limit stop pins of the contact network limit locator mainly adopts a combination of manual regular inspection and technical personnel checking the 4C contact network high-precision images. The former has high labor intensity, long working cycle, and it is not easy to find defects. As for the latter, although the workload of investigation is greatly reduced, the technicians still have to find the limit locator from the huge amount of high-precision image data of the contact network, and then analyze and judge the residual state of the limit stop pin, which is time-consuming and labor-intensive, and it is very easy to miss the detection due to visual fatigue. Therefore, designing a system for automatic and intelligent detection and monitoring of various faults for high-precision images of the contact network has become a problem that needs to be faced. Designing an intelligent system for detecting the residual state of the limit locator stop pin is of great practical significance for ensuring the safe operation of the contact network.

目前对于接触网高清图像中限位定位器止钉余量是否存在过多或不足两种缺陷状态的检测,并没有很好的方法,依旧停留在人工查看高清图片的阶段,国内外对于接触网限位定位器止钉余量状态智能化分析的研究都很少,利用高精度图像来检测限位定位器止钉余量状态的方法也近乎于无。At present, there is no good method to detect whether there are too many or insufficient limit locator stop nails in the high-definition images of the contact network. It is still at the stage of manually viewing high-definition images. There is little research on intelligent analysis of the limit locator stop nail remainder status of the contact network at home and abroad, and there is almost no method to use high-precision images to detect the limit locator stop nail remainder status.

When the following three conditions are met at the same time, the margin is determined to be appropriate: (1) the input locator detection result exists; (2) the input nail stop ring and the nail stop detection result exist at the same time and each is unique; (3) the ratio of the calculated nail stop margin pixel value to the nail stop width pixel value is within a preset threshold range;

判断结果输出403:模块403将模块402得到的分析结果进行输出,通过将止钉余量状态的充足与否,抽象的转换成了计算止钉余量像素值与止钉长度像素比例的方式,能很好的分析止钉余量的状态,从而绕过了因图片拍摄时摄像机距离远近而导致的定位器大小无法准确量化为具体值的问题。Judgment result output 403: Module 403 outputs the analysis result obtained by module 402. By abstractly converting the sufficiency of the stop nail margin state into a method of calculating the ratio of the pixel value of the stop nail margin to the pixel of the stop nail length, the state of the stop nail margin can be well analyzed, thereby bypassing the problem that the locator size cannot be accurately quantified into a specific value due to the distance of the camera when the picture is taken.
