Detailed Description
For the purposes of making the objects, technical solutions and advantages of the present specification more apparent, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present specification and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the disclosure, are intended to be within the scope of the present application based on the embodiments described herein.
In order to monitor the crack state of the steel rail, a piece of thin paper is tightly attached to the intact steel rail, and if the steel rail is cracked due to external force in the daily use process, the piece of paper also generates cracks in the same way, and even cracks in advance.
Based on the above, the invention provides a thin film type flexible device which is used for replacing paper to monitor the state of the rail crack, when the rail is cracked under the action of external force, the sensitive metal grid in the sensor is broken, and the resistance signal output by the sensor is changed, so that the state of the rail crack is monitored.
The following describes in detail the technical solutions provided by the embodiments of the present application with reference to the accompanying drawings.
Fig. 1 is a schematic diagram of a sensor for monitoring a rail crack state in the present specification, and as can be seen from fig. 1, the sensor for monitoring a rail crack state includes an insulating layer 1, a sensitive grid 2, and a protective layer 3.
In particular, in one or more embodiments of the present disclosure, the insulating layer 1 is used to adhesively secure the sensor to the rail and to isolate the rail from the sensitive grid within the sensor. That is, the adhesive can be attached to the surface of the insulating layer 1, which is in contact with the steel rail, so that the sensor is integrally and tightly adhered to the steel rail through the adhesive, and external force acting on the steel rail can act on the sensor at the same time, thereby reflecting the state of the steel rail through the state of the sensor. Meanwhile, in order to avoid leakage of the sensitive grid 2 to the steel rail, the sensitive grid and the steel rail are isolated through the insulating layer 1, misjudgment of the state of the sensitive grid 2 caused by leakage is avoided, and the accuracy of monitoring the state of the steel rail crack is improved. The specific insulating material used to form the insulating layer 1 may be determined as desired, and this is not limited in this specification.
The sensitive grid electrode 2 is arranged on the insulating layer 1, when the steel rail is cracked under the action of external force, at least part of metal wires in the sensitive grid electrode 2 are simultaneously cracked along with the occurrence of the cracking of the steel rail, and the resistance is increased. The sensor grid 2 may comprise a plurality of wires, each of which may be adapted to change in response to changes in rail stress conditions. For example, when the rail breaks or cracks, at least a portion of the wire is correspondingly forced to break. The number and arrangement of the specific wires can be determined as required, and the specification does not limit the number and arrangement. For example, a simple tiled arrangement may be provided.
The protective layer 3 is arranged on the sensitive grid electrode 2 and isolates the sensitive grid electrode 2 from the outside. The protective layer 3 may be a coating layer formed of a material having one or more of excellent insulation, corrosion resistance, and chemical stability. The sensitive grid electrode 2 is wrapped through the protective layer 3 and the insulating layer 1, so that the sensitive grid electrode 2 is isolated from the steel rail and the external environment, and the sensor can reliably monitor the state of the steel rail for a long time under a complex working condition.
The sensor for monitoring the state of the rail crack shown in fig. 1 comprises an insulating layer, a sensitive grid and a protective layer, wherein the sensor is integrally stuck and fixed with the rail, the sensitive grid in the sensor can be sensitive to correspondingly change along with the state change of the rail, and then the state of the rail crack can be reflected through the resistance state of the sensitive grid. The state of the rail crack can be effectively monitored.
Fig. 2 is a schematic cross-sectional view of a sensor for monitoring a rail crack state in the present specification, and as can be seen from fig. 2, the sensor integrally includes a 4-layer structure from inside to outside, which are respectively: the metal wires of the metal grid electrode are represented by four small rectangular frames in the inner part, a protective layer and an insulating layer which are covered on the metal grid electrode, and an encapsulation layer of which the whole is encapsulated by the outermost layer.
When applied, the metal gate and the insulating layer are the same as those described above, and are not described in detail herein, and for the protective layer, in one or more embodiments of the present disclosure, the protective layer may specifically include: an encapsulation layer and a protection layer.
The protective layer is arranged on the sensitive grid electrode, insulates the sensitive grid electrode from the outside, and electrically protects the sensitive grid electrode. And the packaging layer is arranged on the protective layer, so that the whole sensor is sealed and protected, and the sensitive grid is prevented from being broken due to external impact or aging. Of course, the sensor can be prevented from falling off the rail due to impact or aging.
In addition, in practical application, the outdoor ordinary steel rail is generally not easy to break or crack under the normal working condition, and the point rail used for adjusting the running direction of the train in the steel rail is easy to break or crack due to the high-strength working condition.
Thus, in one or more embodiments of the present description, since the point rail generally corresponds to only a small section of rail, the sensor may be elongated and the insulating layer 1 may be used to adhesively secure the sensor to the point rail in accordance with the direction of laying the point rail. That is, the length of the point rail having a high use strength is covered in the laying direction by the strip-shaped sensor, and then whether or not the crack state of the point rail is present is monitored by the sensor.
Further, in one or more embodiments of the present disclosure, the sensing grid may be an arch-shaped wire forming a symmetrical parallel metal grid structure, as shown in fig. 3.
Fig. 3 is a schematic diagram of a sensitive gate in the present specification, wherein two black blocks on the left side of fig. 3 are two electrodes of the sensitive gate, and the two electrodes can be connected with a wire, so as to output a resistance value of the sensitive gate. The right side of the structure of the metal grid in fig. 3 is the structure setting of the metal grid, when the steel rail attached by the sensor generates cracks, the symmetrical parallel metal grid structure can be sequentially broken from outside to inside to cause the resistance value of the metal grid to change, so that the crack condition of the steel rail can be further judged according to the resistance value of the metal grid, and the detection accuracy of the sensor to the state of the steel rail cracks is further improved.
Further, in one or more embodiments of the present disclosure, the sensitive gate is a metal gate structure with a low temperature coefficient of resistance and a high resistivity, for example, a metal gate structure with a temperature coefficient of resistance of less than ±4x10e (-5)/deg.c and a resistivity of greater than or equal to 0.48 μΩ·m may be selected as the sensitive gate. Therefore, the influence of the temperature and the deformation of the sensor on the signals under different working conditions is not beyond the signal change caused by fracture. The specific metal gate structure to be used can be determined according to needs, and the specification does not limit the specific metal gate structure.
In addition, the specification also provides a physical object and an application schematic diagram of the sensor for monitoring the rail crack state, as shown in fig. 4.
Further, the present disclosure also provides a schematic diagram of the change of the resistance of the sensitive gate in the sensor for monitoring the crack state of the rail, as shown in fig. 5. In fig. 5, the horizontal axis represents the number of wires of the broken sensitive gate electrode, and the vertical axis represents the resistance value of the sensitive gate electrode. It can be seen that as the state of the rail crack changes, the number of wires of the broken sensitive grid is larger, the resistance of the sensitive grid is also larger, and the change rate is also increased.
Based on the sensor for monitoring the state of the rail crack shown in fig. 1, the present disclosure further provides a flow chart of a rail crack monitoring method, as shown in fig. 6, specifically including the following steps:
s101: and acquiring resistance values of a plurality of sensors for monitoring the rail crack state.
In general, a server of a service platform for monitoring the state of a steel rail can receive data uploaded by sensors arranged on a plurality of steel rails, namely, the server can acquire resistance values of a plurality of sensors for monitoring the state of cracks of the steel rail, and then judge the states of the steel rails according to the resistance values to determine whether the cracks appear.
The server mentioned in the present specification may be a server provided on a service platform, or a device such as a desktop, a notebook, or the like capable of executing the aspects of the present specification. For convenience of explanation, only the server is used as the execution subject.
S102: for each sensor, whether the resistance value of the sensor is larger than the standard resistance value is respectively judged according to the preset standard resistance value, if so, step S103 is executed, and if not, the judgment of the next sensor is continued.
S103: if yes, determining that the steel rail section provided with the sensor has cracks.
After the resistance value uploaded by each sensor is obtained, the server can preset the resistance value measured when each metal wire of the metal grid in the sensor is not broken as a standard resistance value, and respectively judge whether the resistance value of the sensor is larger than the standard resistance value according to the standard resistance value, if so, the situation that at least part of the metal wires of the metal grid in the sensor are broken is indicated, and the corresponding steel rail section is most likely to be cracked. The follow-up server can correspondingly record the monitoring information and report the monitoring information to a steel rail maintainer so that the monitoring information can be checked and processed on the section of steel rail.
Of course, during the application process, the resistance of the sensor may also be related to the external environment, such as the ambient temperature, so when the state of the rail is judged according to the resistance of the sensor, it can be judged according to the application situation whether the resistance value of the sensor is significantly greater than the preset standard resistance value.
For example, in order to avoid inaccurate judgment caused by external interference to the resistance of the sensor, a gap threshold may be preset, and then the server may determine, according to the standard resistance, whether the resistance of the sensor is greater than the standard resistance, and whether the gap between the two is greater than the preset gap threshold, if so, it indicates that at least part of the metal wires of the metal grid in the sensor are broken, and the corresponding steel rail section is most likely to have cracks. By setting the gap threshold, misjudgment caused by external interference is avoided, and the accuracy of judging the state of the rail crack is improved.
Further, in one or more embodiments of the present disclosure, for a case where a crack is detected in a rail, the server may predict the crack level of the rail according to the change level of the resistance value of the corresponding sensor. The relationship between the degree of cracking of the rail and the degree of change in the resistance value can be determined by preliminary experiments.
Based on the rail crack monitoring method shown in fig. 1, the resistance values of a plurality of sensors for monitoring the rail crack state are acquired first, then for each sensor, whether the resistance value of the sensor is larger than a standard resistance value is judged according to a preset standard resistance value, and if yes, the occurrence of cracks on the rail section provided with the sensor is determined.
According to the invention, the state change of the steel rail is reflected according to the preset change of the resistance value of the sensor for monitoring the state of the steel rail crack, so that whether the steel rail is cracked or not is monitored, and the real-time performance, accuracy and convenience of the steel rail crack monitoring are improved.
When the rail crack monitoring method provided in the present specification is applied, the method may not be executed according to the sequence of steps shown in fig. 6, and the specific execution sequence of the steps may be determined according to needs, which is not limited in the present specification.
