Referring to fig. 1 and 2, an embodiment of the present application provides a train pipe inspection system 10 for use with a 25t axle weight aluminum alloy coal hopper car 20. In one embodiment, the train pipe inspection system 10 may also be applied to other railway freight vehicles. The 25t axle weight aluminum alloy coal hopper wagon 20 comprises an end wall vertical plate 101, a supporting plate 102 and a bottom plate 103.
The train pipe inspection system 10 includes: strain gauge pressure sensor 100, pressure switch 200, control device 300 and host computer 400. The strain gauge pressure sensor 100 is disposed in an installation space 104 formed by the end wall riser 101, the support plate 102 and the bottom plate 103. The strain gauge pressure sensor 100 is communicated with a train pipe 110 of the 25t axle weight aluminum alloy coal hopper car 20. The pressure switch 200 is disposed in the installation space 104. The pressure switch 200 is communicated with the train pipe 110 of the 25t axle weight aluminum alloy coal hopper car 20.

The control device 300 is electrically connected to the strain gauge pressure sensor 100 and the pressure switch 200, respectively.
When the control device 300 receives the trigger signal, the control device 300 detects a current pressure value in the train pipe 110 by the strain gauge pressure sensor 100, and outputs the current pressure value. The upper computer 400 is in communication connection with the control device 300. The upper computer 400 is configured to receive the current pressure value, and determine whether the pressure in the train pipe 110 is normal according to the current pressure value.
In one embodiment, the end wall riser 101 may be made of aluminum alloy. Similarly, the material of the bottom plate 103 may be aluminum alloy. In one embodiment, the material of the supporting plate 102 may be an aluminum alloy. Other materials, such as steel, may be used for the support plate 102.
In one embodiment, the headwall riser 101, the support plate 102, and the bottom plate 103 surround to form an installation space 104. Specifically, the supporting plate 102 is fixedly connected to the end wall vertical plate 101 and the bottom plate 103, the bottom plate 103 is fixedly connected to the end wall vertical plate 101, and the end wall vertical plate 101, the supporting plate 102 and the bottom plate 103 surround and form the installation space 104. Wherein, the installation space 104 is located at one side of the support plate 102 close to the end wall vertical plate 101. In one embodiment, the cross-sectional profile of the installation space 104 in the direction of travel of the 25t axle weight aluminum alloy coal hopper car 20 may be triangular. Therefore, the supporting capability of the supporting plate 102 can be improved, and the stability of the overall structure of the 25t axle weight aluminum alloy coal hopper car 20 can be improved.
In one embodiment, the manner in which the strain gauge pressure sensor 100 is disposed in the installation space 104 is not limited as long as the strain gauge pressure sensor 100 is secured in the installation space 104. In one embodiment, the strain gauge pressure sensor 100 is disposed in the installation space 104 and is fixedly connected to the bottom plate 103 by bolts. In one embodiment, the strain gauge pressure sensor 100 may also be fixedly connected to the bottom plate 103 by a snap-fit manner.
In one embodiment, the strain gauge pressure sensor 100 may be a resistive strain gauge pressure sensor. The resistance strain type pressure sensor has the advantages of small volume, light weight, high precision, adaptability, high temperature, low pressure and the like. The resistance strain type pressure sensor is adopted and matched with a diffusion type strain measurement method, large strain is diffused, and good linearity is guaranteed, so that the resistance strain type pressure sensor is more finely installed and stable in measurement.
It can be understood that the manner of communicating the strain gauge pressure sensor 100 with the train pipe 110 of the 25t axle weight aluminum alloy coal hopper car 20 is not limited as long as the strain gauge pressure sensor 100 is in communication with the train pipe 110. In one embodiment, the strain gauge pressure sensor 100 may be in communication with the train pipe 110 via a hose and a three-way valve. The strain gauge pressure sensor 100 may also be in direct communication with the train pipe 110 through a three-way valve. This may enable the strain gauge pressure sensor 100 to detect pressure changes within the train pipe 110 in real time.
It should be understood that the manner of communicating the pressure switch 200 with the train pipe 110 of the 25t axle weight aluminum alloy coal hopper car 20 is not limited, as long as the pressure switch 200 is communicated with the train pipe 110. In one embodiment, the pressure switch 200 may be in communication with the train pipe 110 via a hose and a three-way valve. The pressure switch 200 may also be in direct communication with the train pipe 110 through a three-way valve. This may enable the pressure switch 200 to detect pressure changes within the train pipe 110 in real time.
In one embodiment, the pressure switch 200 is used to determine whether to output a trigger signal according to the pressure value of the train pipe 110. Specifically, when the pressure value of the train pipe 110 gradually increases and reaches the first pressure threshold, the pressure switch 200 outputs the trigger signal to the control device 300. That is, when the pressure value of the train pipe 110 gradually increases to be equal to the first pressure threshold value, the pressure switch 200 outputs the trigger signal to the control device 300. When the control device 300 receives the trigger signal, the control device 300 is awakened. At this time, the control device 300 detects a current pressure value inside the train pipe 110 by the strain gauge pressure sensor 100 and outputs the current pressure value. And when the control device 300 outputs the current pressure value, the control device 300 automatically enters a sleep state. In one embodiment, the specific value of the first pressure threshold can be set according to the actual requirement of the 25t axle weight aluminum alloy coal hopper car 20, and is not limited to the specific value.
When the pressure value of the train pipe 110 gradually decreases and reaches the second pressure threshold, the pressure switch 200 also outputs the trigger signal to the control device 300. That is, when the pressure value of the train pipe 110 is gradually decreased to be equal to the second pressure threshold value, the pressure switch 200 outputs the trigger signal to the control device 300. When the control device 300 receives the trigger signal, the control device 300 is awakened. At this time, the control device 300 detects a current pressure value in the train pipe 110 by the strain gauge pressure sensor 100 and outputs the current pressure value. And when the control device 300 outputs the current pressure value, the control device 300 automatically enters a sleep state. Thus, the pressure in the train pipe 110 can be detected in real time, and the running safety of the hopper car is improved.
In one embodiment, the specific value of the second pressure threshold can be set according to the actual requirement of the 25t axle weight aluminum alloy coal hopper car 20, and is not limited herein. In one embodiment, the first pressure threshold is greater than the second pressure threshold. That is, the first pressure threshold may be an upper limit alarm value of the pressure switch 200, and the second pressure threshold may be a lower limit alarm value of the pressure switch 200.
It is to be understood that the manner in which the control device 300 is electrically connected to the strain gauge pressure sensor 100 and the pressure switch 200, respectively, is not limited as long as it is ensured that the strain gauge pressure sensor 100 can transmit the detected pressure value to the control device 300. In one embodiment, the control device 300 may be electrically connected to the strain gauge pressure sensor 100 through a wire. Specifically, the material of the conductive wire is not limited, and for example, the material of the conductive wire may be copper or aluminum. In one embodiment, the control device 300 may also be directly electrically connected to the strain gauge pressure sensor 100.
It is to be understood that the specific structure of the control device 300 is not limited as long as it has a function of detecting a current pressure value inside the train pipe 110 by the strain gauge pressure sensor 100 and outputting the current pressure value. In one embodiment, the control device 300 may be an MCU (micro control unit). The control device 300 may also be an integrated control chip.
In one embodiment, the control device 300 wakes up when the control device 300 is receiving the trigger signal. I.e. the control device 300 enters the active state from the sleep state. At this time, the control device 300 may detect a current pressure value in the train pipe 110 through the strain gauge pressure sensor 100, and output the current pressure value to the upper computer 400. And when the control device 300 outputs the current pressure value, the control device 300 automatically enters a sleep state. This reduces the overall power consumption of the train pipe inspection system 10.
The control device 300 can detect the current pressure value in the train pipe 110 through the logic, and outputs the current pressure value to the upper computer 400, so that the upper computer 400 determines whether the pressure in the train pipe 110 is normal according to the current pressure value, thereby realizing the air test and inspection of the train pipe 110 of the 25t axle weight aluminum alloy coal hopper car 20 and improving the inspection efficiency.
In one embodiment, the communication mode between the upper computer 400 and the control device 300 is not limited as long as the communication between the upper computer 400 and the control device 300 is ensured. In one embodiment, the upper computer 400 and the control device 300 can communicate with each other in a 4G/5G communication manner. The upper computer 400 and the control device 300 can also adopt other communication modes to realize communication, such as WiFi, bluetooth and the like.
In one embodiment, when the upper computer 400 receives the current pressure value, the upper computer 400 may compare the current pressure value with a third pressure threshold and a fourth pressure threshold, respectively. Further, the upper computer 400 may compare the current pressure value with the third pressure threshold value and the fourth pressure threshold value respectively. If the current pressure value is greater than the third pressure threshold value or the current pressure value is less than the fourth pressure threshold value, it is determined that the pressure in the train pipe 110 is abnormal.
Specifically, if the current pressure value is greater than the third pressure threshold value, it is determined that the pressure in the train pipe 110 is in an overpressure state. If the current pressure value is smaller than the fourth pressure threshold value, it is determined that the pressure in the train pipe 110 is in an under-pressure state. In one embodiment, when the upper computer 400 determines that the pressure inside the train pipe 110 is abnormal, an abnormality alarm may be issued. For example, the upper computer 400 may alarm through an indicator light. The upper computer 400 can also pop up a warning window through the display platform to give an alarm.
In one embodiment, if the current pressure value is less than or equal to the third pressure threshold value, or the current pressure value is greater than or equal to the fourth pressure threshold value, it is determined that the pressure in the train pipe 110 is normal. Namely, the upper computer 400 does not perform alarm prompt at this time.
In one embodiment, the specific values of the third pressure threshold and the fourth pressure threshold can be set according to the actual requirements of the 25t axle weight aluminum alloy coal hopper car 20, and are not limited to the specific values. In one embodiment, the third pressure threshold is greater than the fourth pressure threshold. That is, the third pressure threshold may be an upper limit alarm value of the train pipe 110, and the fourth pressure threshold may be a lower limit alarm value of the train pipe 110.
In this embodiment, the strain gauge pressure sensor 100 is disposed in an installation space 104 formed by the vertical end wall plate 101, the support plate 102 and the bottom plate 103, and the strain gauge pressure sensor 100 is communicated with a train pipe 110 of the 25t axle-load aluminum alloy coal hopper car 20. The pressure switch 200 is disposed in the installation space 104, and whether a trigger signal is output is determined by the pressure switch 200 according to a pressure value of the train pipe. When the control device 300 receives the trigger signal, the control device 300 detects a current pressure value in the train pipe 110 through the strain gauge pressure sensor 100, and outputs the current pressure value to the upper computer 400. The upper computer 400 determines whether the pressure in the train pipe 110 is normal according to the current pressure value, so that the pressure in the train pipe 110 is patrolled, the patrolling time is reduced, and the patrolling efficiency is improved.
