Problems solved by technology

[0002] With the rapid development of rail transit in recent years, the number of track kilometers has doubled, which has brought about a large increase in the workload of track maintenance. Conventional line maintenance is mainly carried out by manual visual inspection and under the condition of no load on the line. On the one hand, it cannot Timely and comprehensive understanding of the working status and quality of track components. In addition, the static inspection of the line cannot understand the dynamic working status and dynamic response level of the track under load conditions, including the fatigue stress of the rail, the fastening pressure of the fastener and other component safety performance. Therefore, the requirements for real-time safety status monitoring and early warning of track lines have become more urgent. The present invention aims to use modern sensors and communication technologies to establish a real-time track line status information online signal acquisition and monitoring system to reflect the dynamic work of the track and its components in real time. State and dynamic response level, providing efficient, reliable and accurate data for line quality monitoring and line maintenance

Embodiment 1

[0050] During the operation of the track system, it is possible that the track fastener clips become loose or even broken, which will cause hidden dangers to driving safety.

[0051] image 3 Shown is a schematic diagram of the system setup for monitoring the running status of the track with the multifunctional intelligent information elastic backing plate 40 . Four sensor chips 51 are implanted in each multifunctional intelligent information elastic backing plate 40 : that is, implanted strain gauges. The strain gage has a pre-connected flexible signal line 71, which is implanted into the elastic matrix 41 by vulcanization during the manufacture of the elastic gasket. The advantage of using the implanted sensor chip 51 is that the sensor chip 51 is sealed in the elastic matrix 41, which can protect the sensor from being damaged by environmental factors during transportation, installation and use. Implanting a plurality of sensor chips 51 can not only ensure the credibility ...

Embodiment 2

[0056] During the operation of the track system, due to the roughness of the wheel surface and the impact on the track, there will be wavy wear marks on the track surface, that is, the phenomenon of "wave grinding", which is especially obvious in the curved part of the track. The emergence of corrugation not only directly threatens the safety and life of the track and vehicle parts, but also increases the vibration and noise level between the wheel and rail, and affects the comfort and stability of the vehicle during operation.

[0057] Using the multifunctional intelligent information elastic backing plate 40 can monitor the generation process of corrugation and the severity of corrugation, reasonably arrange the period of rail surface polishing, and also provide a large amount of practical information for studying the mechanism of corrugation formation and reducing or eliminating the occurrence of corrugation. Operating data.

[0058] Such as Figure 4 As shown, two kinds o...

Embodiment 3

[0061] The multifunctional intelligent information elastic backing plate 40 is more suitable for use in tunnels with limited space or poor environment, especially in areas where experimenters and equipment are restricted. The sensor chip 51 implanted in the multifunctional intelligent information elastic backing plate 40 used is externally connected with a wireless transmitter, and the wireless transmitter can be driven by an external power supply or a battery. The data transmission frequency of the wireless transmitter can be set as required. At the same time, during the intermittent period of data transmission, the transmitter automatically enters the dormant state to reduce battery energy consumption and prolong battery life.

[0062] The signal of the signal transmitter can be analyzed and stored with a portable receiving analysis instrument.

Abstract

The invention relates to a multifunctional intelligent information elastic cushion plate comprising an elastic matrixes (41) and elastic bodies (42). Sensor chips (51) and flexible signal lines (71) are arranged in the elastic matrixes (41). The sensor chips (51) are connected with an external signal collecting and processing system through the flexible signal lines (71). The sensor chips (51) explore the situation that the multifunctional intelligent information elastic cushion plate produces a strain signal after bearing static pressure, and/or produces an extra dynamic strain signal after bearing extra positive pressure or extra negative pressure, and the strain signal and/or the extra dynamic strain signal are/is output to the external signal collecting and processing system through the flexible signal lines (71) to be analyzed and processed. Compared with the prior art, the working state and quality of railway parts can be known timely and comprehensively, the dynamic working state and the dynamic response level of a railway under the condition of being loaded are known, the operation safety of the railway is guaranteed, and the multifunctional intelligent information elastic cushion plate has the advantages of simple structure, fast installation, convenient adjustment and the like.
