Description

Sensor system of railroad car {SENSOR SVSTEM FOR RAILWAY VEHICLE}

The present invention relates to a sensor system of a railroad vehicle, and more particularly, to a sensor system of a railroad vehicle which minimizes further processing for mounting sensors and improves sensing performance while simplifying wiring such as signal lines.

Currently, parts used in railway vehicles are regularly diagnosed and repaired or replaced when abnormalities are found at the time of diagnosis. However, since the railway system is a mass transportation system, it is likely to be a large accident if an accident occurs in the railway system. Accordingly, in order to reduce accident prevention and maintenance / repair costs, there is a growing need to introduce a condition based maintenance (CBM) system in periodic diagnosis.

In addition, if a slight failure of the parts occurs in addition to the failure of the railway parts that cause a large accident, the railroad car may not reach the destination on time. On-time arrival rate is a very important item in terms of people's benefits and is strictly controlled by the state. Therefore, there is a need for a diagnosis of the condition of railway vehicle parts that can lead to a decrease in on-time arrival rate.

For this diagnosis, a variety of sensors are attached to railway vehicles to detect defects early on major parts of the truck, and various instruments that can accurately diagnose and predict failures in real time by analyzing the data measured by the sensors are equipped. There is a need.

Meanwhile, diagnostic methods for diagnosis targets have been developed in various industries. The possibility of a defect of a diagnosis target may be confirmed through heat, sound, vibration, and the like. The diagnostic method using heat or sound enables a user to easily identify a defect of the diagnosis object, but can only identify a defect of the diagnosis object after the defect of the diagnosis object has progressed considerably. In addition, while the diagnostic method using vibration can predict the defect possibility of the diagnosis object as soon as possible, it is necessary to set the sampling time of the data very short and collect the data. In addition, since the frequency conversion is required to analyze the measured data, memory resources for various calculations may be excessively increased.

However, since railway vehicles have limited memory resources, it is difficult to carry out respective diagnostic methods for various parts of railway vehicles. In addition, when the diagnostic server outside the railway vehicle is to perform each diagnostic method for the various components of the railway vehicle, data must be transmitted from the railway vehicle to the diagnostic server, but the amount of data to be transmitted is too large. there was. Accordingly, it was also very difficult to implement each diagnostic method for various parts of the railway vehicle in a diagnostic server outside the railway vehicle. Furthermore, there is not enough space to install various sensors and measuring instruments in the body of a railway vehicle, and even if the space is secured, it is troublesome to process a separate bolt hole for fastening the sensors and measuring instruments to the railway frame of the railway vehicle. There was this. Moreover, such processing may lower the rigidity of the vehicle body.
