Description
技术领域technical field
本实用新型属于电气化铁路接触网检测技术领域，尤其涉及受电弓接触网系统安全监测与故障诊断领域。The utility model belongs to the technical field of electrified railway catenary detection technology, in particular to the field of safety monitoring and fault diagnosis of a pantograph catenary system.
背景技术Background technique
在高速电气化铁路中，安装于列车车顶的受电弓与架设在轨道线路旁的接触网通过滑动接触实现电能的传输，而接触网-受电弓之间的动态接触力直接反映了弓网系统的受流质量。为了合理评估弓网系统设计参数的匹配关系，掌握高速列车正常服役过程中受流质量的演变规律，需要通过在线监测的方式对弓网系统的动态接触力进行准确监测。In high-speed electrified railways, the pantograph installed on the roof of the train and the catenary erected next to the track line realize the transmission of electric energy through sliding contact, and the dynamic contact force between the catenary-pantograph directly reflects the The flow quality of the system. In order to reasonably evaluate the matching relationship of the design parameters of the pantograph-catenary system, and to grasp the evolution law of the flow-receiving quality of the high-speed train during normal service, it is necessary to accurately monitor the dynamic contact force of the pantograph-catenary system through online monitoring.
目前较为常用的方法是通过力传感器和加速度传感器进行接触力检测，基于受电弓弓头空间力系平衡原理，测量弓头与支架的相互作用力后考虑惯性修正得到弓网接触力，包括文献《铁路技术创新》的《弓网接触力检测关键技术》；《铁道技术监督》的《弓网动态接触力测量方法研究》。但这种方法受弓头滑板弹性变形的影响，需要考虑惯性力、空气动力、摩擦力等诸多因素，而传感器多采用电传感器，易受电磁干扰，高速运行情况下测量精度有限；同时需要考虑高压侧信号采集单元与低压侧信号处理单元间的数据传输、电磁屏蔽等问题，实验装置较为复杂。且常用技术的传感器体积较大，只能通过适当的工装安装在受电弓弓头的外部，从而对受电弓与接触网系统的动力学会有一定的影响。At present, the more commonly used method is to detect the contact force through the force sensor and the acceleration sensor. Based on the balance principle of the space force system of the pantograph head, the pantograph-catenary contact force is obtained by considering the inertia correction after measuring the interaction force between the bow head and the bracket. "Key Technology of Pantograph-catenary Contact Force Detection" in "Railway Technology Innovation"; "Research on Pantograph-catenary Dynamic Contact Force Measurement Method" in "Railway Technical Supervision". However, this method is affected by the elastic deformation of the bow head skateboard, and many factors such as inertial force, aerodynamic force, and friction force need to be considered, while the sensor mostly uses an electric sensor, which is susceptible to electromagnetic interference and has limited measurement accuracy under high-speed operation; at the same time, it needs to consider The experimental device is more complicated for data transmission and electromagnetic shielding between the high-voltage side signal acquisition unit and the low-voltage side signal processing unit. Moreover, the sensors of the commonly used technology are large in size and can only be installed outside the pantograph head through appropriate tooling, which will have a certain impact on the dynamics of the pantograph and catenary system.
相比国内的测量方法，在《Quarterly Report of Railway Technical ResearchInstitute》中2014年发表的《Measurement of the Contact Force of the Pantographby Image Processing Technology》中，采用摄像机测出运动中弓头悬挂弹簧的振动位移，由此计算弓头与支架之间的内力以及振动加速度，从而通过内力和惯性力推导出接触力。另有《Proceedings of SPIE》中2010年发表的《An approach to monitor railwaypantograph-catenary interaction with fiber optic sensors》，通过扫频实验的方式得到由0-200Hz的6个传递函数极值、零点和增益定义的一个离散滤波器，即接触力与光栅应变响应之间的传递函数，以实现对接触力的确定。与上述以受电弓为研究对象的测量方法不同，《Quarterly Report of Railway Technical Research Institute》中2007年发表的《The Pantograph Contact Force Measurement Method in Overhead CatenarySystem Vehicle System Dynamics》，将接触网系统理想化为无限长的柔索，通过在测点位置处布置应变片测量吊弦力以及接触线张力，利用接触网系统在测点处垂直方向的力系平衡原理，实现了测试区间的接触力测量。但就上述接触力测量方法而言，测试精度还有待提高，特别是高速运行时，而且实验装置较为复杂，安装的限制条件也较多。Compared with domestic measurement methods, in the "Measurement of the Contact Force of the Pantographby Image Processing Technology" published in "Quarterly Report of Railway Technical Research Institute" in 2014, a camera is used to measure the vibration displacement of the suspension spring of the bow head in motion. From this, the internal forces between the bow head and the support as well as the vibration acceleration are calculated, so that the contact forces are deduced from the internal and inertial forces. In addition, "An approach to monitor railway pantograph-catenary interaction with fiber optic sensors" published in "Proceedings of SPIE" in 2010 obtained the definition of 6 transfer function extremum, zero point and gain from 0-200Hz through frequency sweep experiment A discrete filter of , the transfer function between the contact force and the grating strain response, is used to determine the contact force. Different from the above-mentioned measurement method with pantograph as the research object, "The Pantograph Contact Force Measurement Method in Overhead Catenary System Vehicle System Dynamics" published in "Quarterly Report of Railway Technical Research Institute" in 2007 idealized the catenary system as For the infinitely long flexible cable, strain gauges are arranged at the measuring point to measure the hanging string force and the tension of the contact wire, and the contact force measurement in the test area is realized by using the force system balance principle of the catenary system in the vertical direction at the measuring point. However, as far as the above-mentioned contact force measurement method is concerned, the test accuracy needs to be improved, especially in high-speed operation, and the experimental device is relatively complicated, and there are many restrictions on installation.
