Technical Field
[0001] This invention belongs to the field of track monitoring technology, specifically, it relates to a track health visualization monitoring system. Background Technology
[0002] In recent years, with the rapid development of my country's economy, my country's rail engineering is gradually developing towards large-scale and modern directions. As the scale of rail engineering projects continues to increase, the damage they suffer from long-term environmental impacts and operation will gradually accumulate, thus reducing their safety performance. When a sudden incident occurs, these safety hazards will inevitably lead to catastrophic consequences. Therefore, for the normal operation and structural health of rail engineering projects, safety monitoring and management are essential.
[0003] Existing track health monitoring systems typically only select one type of data when processing and analyzing it, which leads to low monitoring efficiency. Furthermore, different data structures require different processing and analysis methods, which in turn require different algorithms and models, resulting in high maintenance costs.
[0004] Furthermore, the orbital health monitoring system generates a large amount of data, which may need to be transmitted at a high frequency. Current health monitoring systems require longer transmission times when the data volume or frequency is too large, leading to increased latency. Summary of the Invention

[0006] Specifically, the present invention provides a track health visualization monitoring system, including a server, a terminal, and multiple sensing devices, wherein the sensing devices are arranged at track locations to detect track health data; the server receives the detection data transmitted by the sensing devices and stores it in a database in the memory; and retrieves the detection data of the selected sensing device from the memory according to the instructions of the terminal, performs function calculations to obtain a return value; the terminal is used to select the sensing device, send the corresponding sensing device location information to the server, and visualize the return value in an image format.
[0007] In one implementation, the function is a MATLAB function.
[0008] In one implementation, the return value obtained through function operation is also transmitted to a database in memory for subsequent querying and analysis.
[0009] In one embodiment, the system further includes a wireless transmission module through which the detection data from the sensing device is transmitted to the server.
[0010] In one implementation, the data detected by the transmission sensing device is compressed and transmitted to the server via a wireless transmission module, and then decompressed before being calculated by the function.
[0011] In one embodiment, the sensing device includes:
[0012] Monitoring equipment installed on one side of the track body;
[0013] The monitoring base point is located on the track body and corresponds to the monitoring end of the monitoring equipment. The position of the monitoring base point is monitored by the monitoring equipment.
[0014] A protective sleeve is installed on the monitoring end and monitoring base point of the monitoring equipment to form a closed protective cavity. One end of the protective sleeve is open and is inserted into the outer shell of the monitoring equipment. The other end of the protective sleeve is fixedly connected to the side wall of the track body. The monitoring base point is fixedly connected to the end of the protective sleeve away from the open end.
[0015] A protective gas filling assembly is used to fill the sealed protective cavity with protective gas.
[0016] In one embodiment, the sensing device includes a corrugated portion disposed on the side of the protective sleeve near the monitoring device.
[0017] In one embodiment, an annular airbag ring is fixedly connected to the open end of the protective sleeve, and the outer shell of the monitoring device has a corresponding insertion groove for the annular airbag ring. The annular airbag ring is used to seal the space between the protective sleeve and the outer shell of the monitoring device.
[0018] In one embodiment, the protective gas filling assembly includes a piston cylinder, in which a piston rod with a piston at one end is slidably connected. The piston cylinder is provided with a protective gas inlet pipe and a protective gas outlet pipe, which are connected to a first gas chamber of the piston cylinder. The end of the protective gas outlet pipe away from the piston cylinder leads into a protective sleeve. Both the protective gas inlet pipe and the protective gas outlet pipe are provided with a first one-way valve.
[0019] The present invention also provides a method for visual monitoring of track health, which is implemented using the monitoring system described in any of the above claims, the method comprising:
[0020] 1) The server receives and stores the detection data from each sensor device;
[0021] 2) The terminal selects some sensor locations and sends the data to the server;
[0022] 3) The server retrieves the detection data from the sensor devices at the corresponding locations and obtains the return value according to the function;
[0023] 4) The terminal visualizes the returned value as an image.
[0024] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0041] Reference Figure 1-2 The track health visualization monitoring system of the present invention includes a server, a terminal, and multiple sensing devices, wherein the sensing devices are arranged at track locations to detect track health data; the server receives the detection data transmitted by the sensing devices and stores it in a database in the memory; and retrieves the detection data of the selected sensing device from the memory according to the instructions of the terminal, performs function calculations to obtain a return value; the terminal is used to select the sensing device, send the corresponding sensing device location information to the server, and visualize the return value in an image manner.
[0042] With this approach, users can interact with the terminal's interface to monitor specific locations of various sensors, making track health monitoring more targeted and visualized.
[0043] In one implementation, the function is a MATLAB function. MATLAB provides a rich variety of plotting functions and visualization tools, which can flexibly create various types of charts and graphs to display the distribution, trends, and correlations of health monitoring data. MATLAB offers a wealth of data processing functions and toolboxes, including signal processing, image processing, and statistical analysis, which can easily process various types of health monitoring data. MATLAB can interact and integrate with other commonly used health monitoring devices and software, such as biosensors and database systems, facilitating data import and export.
[0044] In one embodiment, the return value obtained through function operations is also transmitted to the database in the memory for subsequent query and analysis. Specifically, the transmission can be executed according to the terminal operation instruction, or the transmission can be automatically sent to the database in the memory after the function calculation. The memory can be a separate memory device or the memory built into the server or terminal.
[0045] In one embodiment, the system further includes a wireless transmission module, and the detection data of the sensing device is transmitted to the server through the wireless transmission module.
[0046] In one embodiment, the detection data of the transmission sensing device is compressed and then transmitted to the server through the wireless transmission module, and after decompression, it is calculated by the function.
[0047] In one embodiment, as Figure 3 shown, the compression is implemented by the following method:
[0048] Step 1: The network data of the sensing device can be regarded as a sequence data x with a length of N. Under normal conditions, this sequence signal has certain non-sparse characteristics. Introduce a sparse transformation matrix ψ∈R N×N to transform it into sparse data f:
[0049] f = ψx (1)
[0050] Step 2: Based on the working principle of the compressed sensing algorithm, according to the sparse signal and the measurement matrix Φ∈R M×N obtain the observed data y with a length of M, and satisfy the condition: M << N. The observed data is:
[0051] y = Φf (2)
[0052] Step 3: The l0 norm of the observed data y can be solved to obtain the solution of the sparse data f:
[0053]
[0054] s.t. Φf = y (3)
[0055] Step 4: Combining the sparse data and the measurement matrix can generate:
[0056]
[0057] According to equation (1), the exact solution of x can be obtained:
[0058]
[0059]
[0060] By adopting this approach, the data compression time of the sensor network in the monitoring system of this invention is significantly reduced, the data compression speed of the sensor network is accelerated, more sensor network data can be processed in the same amount of time, and the data compression efficiency of the sensor network is improved.
[0061] This application also provides a visual monitoring method, such as Figure 2 As shown, it is implemented using the aforementioned monitoring system, and the method includes:
[0062] 1) The server receives and stores the detection data from each sensor device;
[0063] 2) The terminal selects some sensor locations and sends the data to the server;
[0064] 3) The server retrieves the detection data from the sensor devices at the corresponding locations and obtains the return value according to the function;
[0065] 4) The terminal visualizes the returned value as an image.
[0066] In one implementation, the method further includes transferring the return value obtained through function operation to a database in memory.
[0067] In one implementation, the function is a MATLAB function. MATLAB provides a rich variety of plotting functions and visualization tools, which can flexibly create various types of charts and graphs to display the distribution, trends, and correlations of health monitoring data. MATLAB offers a wealth of data processing functions and toolboxes, including signal processing, image processing, and statistical analysis, which can easily process various types of health monitoring data. MATLAB can interact and integrate with other commonly used health monitoring devices and software, such as biosensors and database systems, facilitating data import and export.
[0068] In one embodiment, the detection data from the sensing device is transmitted wirelessly to a server. Preferably, the detection data is compressed before transmission and decompressed on the server.
[0069] In one implementation, the compression is achieved using the following method:
[0070] Step 1: The network data of the sensing device can be regarded as a sequence of data x with a length of N. Under normal conditions, this sequence signal has certain non-sparse characteristics. A sparse transformation matrix ψ∈R is introduced. N×N Transform it into sparse data f:
[0071] f = ψx (1)
[0072] Step 2: Based on the working principle of the compressive sensing algorithm, according to the sparse signal and the measurement matrix Φ ∈ R M×N obtain the observation data y, whose length is M and satisfies the condition: M << N. The observation data is:
[0073] y = Φf (2)
[0074] Step 3: The l0 norm of the observation data y can be solved to obtain the solution of the sparse data f:
[0075]
[0076] s.t. Φf = y (3)
[0077] Step 4: Combining the sparse data and the measurement matrix can generate:
[0078]
[0079] According to Equation (1), the exact solution of x can be obtained:
[0080]
[0081]
[0082] Adopting the above solution, users can achieve specific monitoring of the positions of each sensing device through page interaction with the terminal, making the track health monitoring more targeted. Moreover, the data compression time of the sensing device network is significantly reduced, accelerating the data compression speed of the sensing device network. In the same time, more sensing device network data can be processed, improving the data compression efficiency of the sensing device network.
[0083] In addition, an important factor affecting track health is track settlement. However, the sensing device is easily affected by the environment, affecting the accuracy of the detection data, and thus resulting in inaccurate final monitoring results. Therefore, in one embodiment, referring to Figures 4-12The sensing device includes: a monitoring device 2 disposed on one side of the track 1; a monitoring base point 24 located on the track 1, the monitoring base point 24 corresponding to the monitoring end of the monitoring device 2, the position of the monitoring base point 24 being monitored by the monitoring device 2; a protective sleeve 21 disposed on the monitoring end of the monitoring device 2 and the monitoring base point 24 to form a closed protective cavity, one end of the protective sleeve 21 being open and plugged into the outer shell of the monitoring device 2, the other end of the protective sleeve 21 being plugged into the monitoring device 2, facilitating the installation of the protective sleeve 21 on the monitoring device 2, and also facilitating the removal of the protective sleeve 21 from the monitoring device 2 for maintenance of the monitoring end of the monitoring device 2, the other end of the protective sleeve 21 being fixedly connected to the side wall of the track 1, the monitoring base point 24 being fixedly connected to the end of the protective sleeve 21 away from the open end; and a protective gas filling assembly for filling the closed protective cavity with protective gas.
[0084] This device is mainly used to install a protective sleeve 21 between the existing monitoring equipment 2 and the monitoring base point 24 to protect the monitoring end of the monitoring equipment 2 and the monitoring base point 24;
[0085] The protective sleeve 21 can isolate the monitoring end of the monitoring device 2 and the monitoring base point 24 from the outside world, thereby avoiding the influence of the external environment on the monitoring device 2 and the monitoring base point 24. This can effectively improve the accuracy and lifespan of the monitoring of track 1 settlement, reduce the number of maintenance times, and reduce costs for most applicable companies in the track settlement field.
[0086] It is important to understand that the monitoring of track 1 settlement is usually based on the monitoring base point 24 installed on track 1. When track 1 settles, the monitoring base point 24 will also settle. At this time, the monitoring equipment 2 can monitor the settlement of track 1 by observing or measuring the position of the monitoring base point 24.
[0087] However, considering factors such as service life, strength, and how to connect with the track 1, some monitoring base points 24 may be made of metal or plastic. However, both of these materials will suffer varying degrees of wear and tear when used outdoors, leading to a decrease in monitoring performance. At the same time, the monitoring end of the monitoring device 2 also needs to consider the wear and tear that may occur when used outdoors for a long time. Therefore, this device protects the monitoring end of the monitoring device 2 and the monitoring base points 24 by setting a protective sleeve 21, thereby effectively improving service life and monitoring accuracy.
[0088] Meanwhile, in order to further improve the protection effect on the monitoring end of the monitoring device 2 and the monitoring base point 24, this device also sets up a protective gas filling component that can fill the closed protective cavity between the monitoring end of the monitoring device 2 and the monitoring base point 24 with protective gas. On the one hand, the air pressure in the closed protective cavity is greater than the outside air pressure, thereby preventing outside air from entering the closed protective cavity and causing damage to the monitoring end of the monitoring device 2 and the monitoring base point 24. On the other hand, the protective gas can further protect the monitoring end of the monitoring device 2 and the monitoring base point 24, and further reduce the wear of the monitoring base point 24.
[0089] The protective gas can be nitrogen;
[0090] It should be noted that, in order to prevent the monitoring device 2 from settling, a deep pit is dug in the road surface and concrete is poured to form a concrete pile foundation 11. An installation platform 12 is then installed on the exposed concrete pile foundation 11, and the monitoring device 2 is installed on the installation platform 12 to prevent the monitoring device 2 from settling.
[0091] In one embodiment, refer to Figure 6 The protective sleeve 21 has a corrugated part 22 on the side near the monitoring device 2. Since one end of the protective sleeve 21 is fixedly connected to the track 1, when the rail vehicle passes through the track 1, the track 1 will fluctuate up and down to a certain extent. When the track 1 fluctuates up and down, the protective sleeve 21 that is inserted into the outer shell of the monitoring device 2 will become loose, resulting in air leakage in the sealed protective cavity.
[0092] Therefore, by providing a corrugated part 22 on the side of the protective sleeve 21 close to the monitoring device 2, the transmission of vibration between the protective sleeve 21 and the monitoring device 2 can be reduced, thereby improving the sealing performance between the protective sleeve 21 and the monitoring device 2.
[0093] In one embodiment, refer to Figure 6 An annular airbag ring 23 is fixedly connected to the open end of the protective sleeve 21. The outer shell of the monitoring device 2 is provided with a corresponding insertion groove for the annular airbag ring 23. The annular airbag ring 23 is used to seal the space between the protective sleeve 21 and the outer shell of the monitoring device 2.
[0094] By opening a slot on the outer shell of the monitoring device 2, the end of the protective sleeve 21 with the annular airbag ring 23 is inserted into the slot, so that the annular airbag ring 23 fills the slot, which further improves the sealing between the protective sleeve 21 and the monitoring device 2, thereby preventing the leakage of protective gas in the sealed protective cavity.
[0095] In one embodiment, refer to Figure 4 , Figure 10The protective gas filling assembly includes a piston cylinder 34, in which a piston rod 340 with a piston at one end is slidably connected. The piston cylinder 34 is provided with a protective gas inlet pipe 34111 and a protective gas outlet pipe 34121. The protective gas inlet pipe 34111 and the protective gas outlet pipe 34121 are connected to the first gas chamber 341 of the piston cylinder 34. The end of the protective gas outlet pipe 34121 away from the piston cylinder 34 leads to the protective sleeve 21. The protective gas inlet pipe 34111 and the protective gas outlet pipe 34121 are each provided with a first one-way valve.
[0096] By driving the piston rod 340 to slide up and down repeatedly inside the piston cylinder 34, when the piston rod 340 slides up, the protective gas in the gas storage tank is drawn into the first gas chamber 341 through the protective gas inlet pipe 34111. When the piston rod 340 slides down, the protective gas in the first gas chamber 341 is discharged into the closed protective chamber of the protective sleeve 21 through the protective gas outlet pipe 34121.
[0097] Specifically, the outer casing of the monitoring device 2 has a horizontal air inlet groove (not shown in the figure). One end of the air inlet groove passes through the side of the monitoring device 2 near the track 1, and the other end passes through the side of the outer casing of the monitoring device 2. An air nozzle is installed on the side of the air inlet groove that passes through the outer side of the monitoring device 2. The air nozzle is connected to the air inlet groove. The protective gas inlet pipe 34111 is connected to the air nozzle. This allows the protective gas to be filled into the closed protective cavity through the air inlet groove when the piston cylinder 34 presses the protective gas into the protective gas inlet pipe 34111.
[0098] The gas storage tank can be installed in the concrete pile foundation 11. When pouring concrete in the deep pit, an empty slot is set up to install the gas storage tank. The empty slot is set below the ground and a cover is set on the ground. When the cover is opened, the gas storage tank can be observed, which facilitates daily maintenance and replenishment of protective gas for the gas storage tank, and also protects the gas storage tank.
[0099] In one embodiment, refer to Figure 10 The piston cylinder 34 is provided with a second air inlet pipe 3421 and a second air outlet pipe 3422. A second one-way valve is provided in both the second air inlet pipe 3421 and the second air outlet pipe 3422. The second air inlet pipe 3421 and the second air outlet pipe 3422 are connected to the second air chamber 342 in the piston cylinder 34. The end of the second air outlet pipe 3422 away from the piston cylinder 34 is fixedly connected to the annular air bag ring 23.
[0100] As the piston rod 340 slides up and down reciprocally, the second air chamber 342 draws in outside air and discharges it into the annular airbag ring 23, which further expands and fills the insertion groove, thereby further improving the airtightness of the sealed protective cavity and thus improving the protection effect on the monitoring end of the monitoring device 2 and the monitoring base point 24.
[0101] Specifically, the outer casing of the monitoring device 2 has a horizontal second through-slot (not shown in the figure). One end of the second through-slot passes through the insertion slot for installing the annular airbag ring 23, and the other end passes through to the side of the outer casing of the monitoring device 2. When the protective sleeve 21 is installed on the outer casing of the monitoring device 2, one end of the second air outlet pipe 3422 is first inserted into the second through-slot, and then pulled out from the insertion slot. The second air outlet pipe 3422 is then connected to the annular airbag ring 23. Then, when the annular airbag ring 23 is inserted into the insertion slot, the second air outlet pipe 3422 is continuously pulled so that the annular airbag ring 23 can be inserted into the insertion slot.
[0102] In one embodiment, the device further includes: a transmission box 3 and a drive rack 32 and a transmission rack 33 connected to the transmission box 3. A connecting arm 31 is fixedly connected to the track 1. The connecting arm 31 is fixedly connected to the drive rack 32. One end of the transmission rack 33 is fixedly connected to the piston rod 340, so that the drive rack 32 can reciprocate on the transmission box 3 due to vibration when the train passes through the track 1. The drive rack 32 in this device is the same as the drive rack in the prior art, and the transmission rack 33 in this device is the same as the warning rack in the prior art.
[0103] Therefore, when the rail vehicle passes over the track 1 on which the device is installed, the downward pressure of the rail vehicle causes the track 1 to fluctuate up and down. When the track 1 fluctuates up and down, the vibration is transmitted to the drive rack 32 through the connecting arm 31, which increases the amplitude of the vertical fluctuation of the transmission rack 33, thereby driving the piston rod 340 to slide in the piston cylinder 34.
[0104] Both the piston cylinder 34 and the transmission box 3 are installed on the concrete pile foundation 11.
[0105] In one embodiment, refer to Figure 4 , Figure 6 , Figure 8 It also includes: a protective airbag 252 that is fitted over the protective sleeve 21 to provide impact protection for the protective sleeve 21;
[0106] By setting a protective airbag 252 outside the protective sleeve 21, it can be used to protect the protective sleeve 21 and prevent external objects from hitting the protective sleeve 21 and causing damage, deformation, and micro-cracks, as well as deformation causing the protective sleeve 21 to be concave and seriously hindering the monitoring end of the monitoring device 2 from observing the monitoring base point 24.
[0107] Because the railcar travels at a high speed when passing this device, lighter objects in the environment are accelerated, increasing the likelihood of them hitting the protective sleeve 21. There is also the possibility of stones flying and hitting the protective sleeve 21.
[0108] Furthermore, both ends of the protective sleeve 21 are fixedly connected to annular slide rails 25, and both ends of the protective airbag 252 are fixedly connected to connecting rings 251, which are rotatably connected in the annular slide rails 25; it also includes: an external gear ring 250 fixedly connected to the connecting ring 251 near the end of the monitoring device 2, a mounting box 261 provided on the outer shell of the monitoring device 2, the mounting box 261 being installed in the mounting groove 26 on the outer shell of the monitoring device 2, and a rotating shaft 262 rotatably connected in the mounting box 261. A turbine blade assembly 263 is fixedly connected to the outer periphery. A gear 264 is fixedly connected to one end of the rotating shaft 262 that extends through the mounting box 261. The gear 264 meshes with the external gear ring 250. A connecting pipe is fixedly connected to the annular airbag ring 23. An overflow valve is provided on the connecting pipe. The end of the connecting pipe away from the annular airbag ring 23 is fixedly connected to the mounting box 261. The connecting pipe is located in the first through-hole groove 231 in the outer shell of the monitoring device 2, which is used to drive the rotating shaft 262 to rotate and drive the protective airbag 252 to rotate outside the protective sleeve 21.
[0109] In this embodiment, the gas pumped out by the piston cylinder 34 is fully utilized, thereby reducing the use of electrical equipment;
[0110] When the annular airbag ring 23 is inflated, the excess gas will enter the mounting box 261 through the overflow valve on the breakthrough connecting pipe, and blow the turbine blade assembly 263 to make the rotating shaft 262 rotate, and drive the outer gear ring 250 to rotate through the gear 264, thereby driving the protective airbag 252 to rotate outside the protective sleeve 21.
[0111] One benefit of rotating the protective airbag 252 is that it changes the position of the airbag 252 after it is hit, thereby reducing the possibility of being hit in the same position again.
[0112] On the other hand, when the protective airbag 252 is hit by an object while rotating, the rotating protective airbag 252 can effectively absorb and transform the impact force brought by the object. This allows the rotating protective airbag 252 to change the impact angle of the object when the object comes into contact with the surface of the protective airbag 252, thereby effectively reducing the impact force of the object on the protective airbag 252 and thus improving the service life of the protective airbag 252.
[0113] It should be understood that the direction of travel of rail vehicles is relatively uniform. Therefore, the airbag 252 is often hit on the two sides of the circumference perpendicular to the ground. Therefore, by driving the airbag 252 to rotate at irregular and irregular angles, the hit position is changed, thereby reducing the possibility of the airbag 252 being hit repeatedly in the same position, and thus improving the protection of the airbag 252.
[0114] It should be understood that the mounting box 261 is equipped with an exhaust pipe 265 to discharge the gas filled into the mounting box 261, and the end of the exhaust pipe 265 faces the protective airbag 252, which can clean the surface of the protective airbag 252 when the protective airbag 252 rotates.
[0115] In one embodiment, to improve the protective effect of the airbag 252 on the protective sleeve 21, refer to Figure 11 The protective airbag 252 is configured with multiple independent airbag compartments 253. When the protective airbag 252 is hit and damaged, the independent airbag compartments 253 prevent all the gas inside the protective airbag 252 from leaking out, thereby effectively improving the protective performance of the protective airbag 252 on the protective sleeve 21. At the same time, combined with the rotatable characteristic of the protective airbag 252, the leaking independent airbag compartments 253 can be effectively transferred to other angle positions by rotation, so that the device can achieve better use effect.
[0116] In another embodiment, refer to Figure 12 The protective airbag 252 is configured to have multiple independent airbag compartments 253, and cross-shaped reinforcing ribs 254 are provided in the independent airbag compartments 253, so that an independent airbag compartment 253 is divided into four chambers. At the same time, ventilation holes 255 are provided on the reinforcing ribs 254, so that the four chambers are interconnected.
[0117] The reinforcing rib 254 can improve the strength of the protective airbag 252 when it is hit, thus preventing it from being penetrated. On the other hand, the vent 255 allows the gas in one of the four interconnected chambers to be injected into the other chambers when one of the chambers is hit, thereby absorbing the impact force and improving the protective function of the protective airbag 252.
[0118] Furthermore, a connecting rod 27 is fixed between the two connecting rings 251, which can provide support for the protective airbag 252 when it rotates, and further prevent the protective airbag 252 from twisting when it rotates.
[0119] In one embodiment, refer to Figure 10The piston cylinder 34 is equipped with a first three-way solenoid valve 3411 and a second three-way solenoid valve 3412, which are connected to the first air chamber 341. The first three-way solenoid valve 3411 and the second three-way solenoid valve 3412 are respectively equipped with a first air inlet pipe 34112 and a first air outlet pipe 34122. The end of the first air outlet pipe 34122 away from the piston cylinder 34 is fixedly connected to the second air outlet pipe 3422. The first air inlet pipe 34112 and the first air outlet pipe 34122 are respectively provided with a third one-way valve. The protective sleeve 21 is equipped with a pressure sensor 28.
[0120] Furthermore, since a large number of rail vehicles pass through track 1 in a day, the piston cylinder 34 repeatedly fills the closed protective chamber with nitrogen, resulting in excessive gas pressure inside the closed protective chamber. To optimize this problem, this device can achieve the following by installing a first three-way solenoid valve 3411 and a second three-way solenoid valve 3412 on the piston cylinder 34 and cooperating with the pressure sensor 28: when the pressure sensor 28 detects that the gas pressure inside the closed protective chamber has dropped to the set threshold, the first three-way solenoid valve 3411 and the second three-way solenoid valve 3412 connect the protective gas inlet pipe 34111 and the protective gas outlet pipe 34121 to the first gas chamber 341, so as to drive the piston cylinder 34 to fill the closed protective chamber with protective gas when a rail vehicle passes by.
[0121] When the pressure sensor 28 detects that the gas pressure in the sealed protective cavity reaches the set threshold, the first three-way solenoid valve 3411 and the second three-way solenoid valve 3412 disconnect the protective gas inlet pipe 34111 and the protective gas outlet pipe 34121 from the first gas chamber 341, and connect the first inlet pipe 34112 and the first outlet pipe 34122 to the first gas chamber 341. At this time, the first gas chamber 341 and the second gas chamber 342 in the piston cylinder 34 will both fill the annular airbag ring 23 with air, causing the annular airbag ring 23 to expand further, further improving the sealing performance of the sealed protective cavity, and at the same time avoiding the waste caused by filling the sealed protective cavity with too much protective gas.
[0122] This will also increase the rotation frequency of the shaft 262, further absorbing and transforming the splashes.
