车载接触网运行状态检测装置系统设计及应用

接触网作为电气化铁路牵引供电的关键设备,其状态好坏直接影响铁路运行安全。为了在运营动车组上装备一套接触网运行状态检测装置对接触网运行状态进行全程监控,从系统的设计要求、设计原则、设计方案着手,引入非接触式的图像处理、机器视觉以及红外测温关键技术,完成装置的系统设计,同时通过静态和动态试验验证装置的性能。试验和现场的实际应用反馈表明,装置满足技术条件要求,同时装置对接触网的检测结果能够为接触网检修提供依据。

System Design and Application of On-board Overhead Catenary Monitoring Device

Overhead catenary is an important device for traction equipments of electrical railway,therefore the condition of overhead catenary will impact the operation safety for the railway.In order to design a set of device on the operating EMUs to monitor the operation state of the catenary in the whole process,starting from the design requirements,design principles and design scheme of the system,the non-contact image processing,machine vision and infrared temperature measurement key technologies were introduced to complete the system design of the device,and the performance of the device was verified through static and dynamic tests.According to the feedback of test and field application,the device met the requirements of technical conditions.Meanwhile,the detection results of the device on the catenary could provide basis for the maintenance of the catenary.
