Description
技术领域technical field
本实用新型涉及铁路车辆状态监控领域，具体地，涉及一种车辆脱轨监测系统。The utility model relates to the field of railway vehicle state monitoring, in particular to a vehicle derailment monitoring system.
背景技术Background technique
长期以来，世界各国铁路部门和科研人员展开了大量的脱轨技术理论与实验研究，但是由于脱轨问题的复杂性和研究的困难性，车辆脱轨问题至今仍未得到很好的解决，脱轨事故的原因往往也难以查明，甚至评判脱轨的准则至今也存在很多问题。For a long time, railway departments and scientific researchers in various countries in the world have carried out a large number of theoretical and experimental studies on derailment technology. However, due to the complexity of derailment problems and the difficulty of research, the problem of vehicle derailment has not been well resolved so far. The cause of derailment accidents It is often difficult to find out, and even the criteria for judging derailment still have many problems so far.
随着铁路运输需求的逐年增加，提高列车的行驶速度、开行大轴重列车、开行万吨甚至两万吨重载列车是提高铁路运输能力的主要措施，其中重载铁路空载车辆运行提速是增加重载铁路运力和工作效率的有力手段，但因空载时车辆垂向作用力减小，空载车辆因其脱轨系数大于满载车辆而更易发生脱轨，然而，操作人员往往不知道应该以怎样的速度来运行车辆，所以为了防止车辆脱轨情况的发生，操作人员通常需要使车辆以较低的运行速度运行，这不仅影响了铁路的运输效率而且也不能有效防止车辆脱轨。As the demand for railway transportation increases year by year, increasing the speed of trains, running large-axle-load trains, and running 10,000-ton or even 20,000-ton heavy-duty trains are the main measures to improve railway transportation capacity. It is a powerful means to increase the capacity and work efficiency of heavy-haul railways, but because the vertical force of the vehicle is reduced when it is empty, the derailment coefficient of empty vehicles is greater than that of fully-loaded vehicles, so it is more likely to derail. However, operators often do not know how to use it. Therefore, in order to prevent the derailment of the vehicle, the operator usually needs to run the vehicle at a lower speed, which not only affects the transportation efficiency of the railway, but also cannot effectively prevent the derailment of the vehicle.
