Safety evaluation system for rail vehicles

Abstract

The invention provides a system for evaluating safety of rail vehicle. The system includes a display means, a collecting device, a calculating device and an alarming device. The collecting device is composed of a sensor assembly for obtaining vehicle dynamic parameters of the collecting position, the calculating device receives information of the sensor assembly and performs calculation, the calculation result is displayed by a display device, and the alarming device performs positioning and voice alarming on wheelsets at risk of derailment. Based on the sensor device, the invention obtains the real-time dynamic parameters in the running process of the vehicle, obtains the lateral force and the vertical force of the wheelset which are difficult to be measured by the dynamic formula backward, calculates the real-time derailment coefficient of the vehicle, and displays and analyzes the real-time derailment coefficient of the vehicle through the client end. The system can make real-time evaluation of the running safety of rail vehicles in the process of running, help drivers judge whether there is derailment risk, slow down, stop and other operations, and also provide overhaul basis for vehicle overhaul personnel. It has practical application prospect.

Description

technical field [0001] The invention relates to a driving safety evaluation system with an integrated display device, in particular to a rail vehicle safety evaluation system. Background technique [0002] With the rapid development of rail vehicles, the requirements for driving safety are getting higher and higher. Due to the complexity of the wheel-rail contact position, it is difficult to obtain wheel-rail contact force information by direct measurement. The more limited methods of direct measurement of the wheel-rail contact force are: (1) Sticking strain gauges on the track. The limitation of this method is that the wheel-rail force information can only be obtained within a limited length range, and the operability is poor and the cost is high. (2) Force measuring wheel set measurement. The real-time measurement of the wheel-rail contact force of the running vehicle can be realized by installing the force-measuring wheel set on the bogie, but it undoubtedly greatly i...

Problems solved by technology

The real-time measurement of the wheel-rail contact force of the running vehicle can be realized by installing the force-measuring wheel set on the bogie, but it undoubtedly greatly increases the cost, and there is also a big limitation that it cannot impose a large force on the wheel set. Otherwise, the driving safety may be affected. In addition to the direct measurement method, the wheel-rail force can also be obtained through an indirect method.
