Description

Technical Field

[0001] The present application relates to the field of vehicle transportation technology, and in particular to a device for fixing and monitoring the safety status of a transported vehicle. Background Art

[0002] The mass transportation of vehicles is an indispensable transportation activity in the modern efficient economy and society, such as the mass transfer of finished household, industrial and agricultural vehicles, the rapid transfer of military vehicles and equipment such as tanks and armored vehicles, etc. The transportation speed and safety are the direct reflection of a country's technical level. At present, there are several main modes of transportation, including single-vehicle driving, roll-on / roll-off ship batch transportation, railway batch transportation, and large truck batch transportation. Single-vehicle driving is only suitable for short-distance transfer vehicles. It relies on the driver to start the vehicle to the destination, which consumes a lot of energy, has high costs, low efficiency, and damages the locomotive, and is gradually being eliminated. Batch transportation is economical and efficient, and has become the mainstream mode. When transporting in batches, it is inevitable to involve the safe fixation of the vehicle, which directly affects the actual transportation quality. Generally, when transporting vehicles in batches, the vehicle is often reinforced, such as using anchor cables to fix it, and using non-return devices to prevent sliding. Due to the influence of factors such as shaking, ups and downs, turning, and vibration, some anchoring means will become loose and broken, which directly causes serious accidents such as vehicle sliding, dislocation, friction, collision, and even rollover, causing serious economic and military losses.

[0003] Traditional technologies are mostly fixed stabilization devices, and do not use more advanced real-time monitoring technology to monitor the safety of the entire transportation process, which is the key technology urgently needed to effectively improve long-distance transportation vehicles. During the transportation of vehicle equipment, the loaded vehicle equipment is fixed to prevent the vehicle equipment from loosening or detaching from the transportation platform, thereby preventing damage to the vehicle equipment and improving the safety and reliability of transportation.

[0006] In some embodiments, the detection device includes a fiber grating strain sensor and a fiber optic demodulator arranged on the positive tread contact panel, and the fiber optic demodulator is used to demodulate the optical signal measured by the fiber grating strain sensor into a strain value, so that the remote monitoring system executes: generating strain fluctuations according to the strain values ​​recorded by continuous monitoring, and when it is judged that the strain value is less than a first threshold value and the fluctuation amplitude of the strain fluctuation is less than a second threshold value, generating a warning message for indicating that the vehicle equipment is loose.

[0007] In some embodiments, the detection device includes a unidirectional laser ranging sensor fixed on a backplate support column, and a first laser window is provided on the positive tread contact panel.

[0008] In some embodiments, the detection device includes a bidirectional laser ranging sensor fixed on a back plate support column, a first laser window is provided on the forward tread contact panel, and a second laser window is provided on the back plate support column; the forward laser emitted by the bidirectional laser ranging sensor is irradiated onto the surface of the running mechanism of the vehicle equipment through the first laser window, thereby measuring a first distance value, so that when the remote monitoring system determines that the first distance value is greater than a third threshold value, a warning message is generated to indicate that the vehicle equipment is loose; or, the remote monitoring system generates a displacement fluctuation based on the first distance value continuously monitored and recorded, and when it is determined that the fluctuation amplitude of the displacement fluctuation is greater than a fourth threshold value, a warning message is generated to indicate that the vehicle equipment is loose.

[0009] In some embodiments, if the backboard support column is fixed on a fixed pile of the transportation equipment, or the fixed pile and the backboard support column are placed opposite to each other at a certain distance, the backward laser emitted by the bidirectional laser ranging sensor is irradiated onto the fixed pile through the second laser window, thereby measuring the second distance value, so that when the remote monitoring system determines that the second distance value exceeds a preset range, a warning message is generated to indicate that the fixing device is loose or slipping.

[0010] In some embodiments, if multiple vehicle equipment are loaded on a transport device along the length direction, the backward laser emitted by the bidirectional laser ranging sensor is irradiated onto an adjacent vehicle equipment through a second laser window, thereby measuring a third distance value, so that when the remote monitoring system determines that the third distance value is less than a fifth threshold, a warning message is generated to indicate that two adjacent vehicle equipment are about to collide.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] The device for fixing and monitoring the safety status of the transported vehicle provided in the present application comprises a fixing device 1 and a detection device 2 as a whole. The fixing device 1 is used to fix the vehicle equipment 3 during transportation to prevent the vehicle equipment 3 from loosening, sliding, and violently shaking. The detection device 2 is used to measure the connection status between the vehicle equipment 3 and the fixing device 1, obtain the status information, and analyze the status information to identify whether the vehicle equipment 3 is loose, thereby timely detecting the abnormal state of the vehicle equipment 3 when it is fixed during transportation, so as to take reinforcement measures in time, thereby improving the safety and reliability of the transportation of the vehicle equipment. Among them, the status information may include the contact status, relative displacement and / or vibration status between the vehicle equipment 3 and the fixing device 1. The specific structure of the device for fixing and monitoring the safety status of the transported vehicle is described below.

[0033] like Figure 1 In the embodiment shown, the fixing device 1 includes a back plate support column 101, a bottom support plate 102, a positive tread contact panel 103 and a compression tensioning belt 104. The bottom support plate 102 and the back plate support column 101 are vertically connected to each other, and the positive tread contact panel 103 is arranged between the back plate support column 101 and the bottom support plate 102. The shape of the positive tread contact panel 103 should be adapted to the curved surface of the running mechanism 301 of the vehicle equipment 3, so that the running mechanism 301 and the positive tread contact panel 103 can be well matched and contacted. The running mechanism 301 can be in the form of a wheeled or tracked vehicle. For example, for a wheeled vehicle equipment, its tire surface is an arc shape, and the positive tread contact panel 103 can be set to a concave arc shape. The center angle corresponding to the arc shape can be set according to the actual application, and the stability and firmness of the tread positioning and crimping should be ensured, for example, it can be set to a quarter arc. By tightening and fixing the tensioning band 104 , the fixing device 1 can be fixedly connected to the vehicle equipment 3 .

[0034] In some embodiments, an anti-slip block 107 is arranged at the bottom of the bottom support plate. The anti-slip block 107 can increase the friction between the bottom of the fixing device 1 and the transportation equipment 4, thereby avoiding a reduction in the fixing effect due to the sliding of the fixing device 1 and preventing the detection device 2 from having measurement errors or false alarms due to the sliding of the fixing device 1.

[0035] In some embodiments, Figure 2 As shown, a through hole 109 is further provided at the bottom of the bottom support plate, and a Velcro 110 is provided on the compression tensioning belt 104. After the walking mechanism 301 is positioned, the compression tensioning belt 104 is compressed. After the tensioning belt 104 passes through the through hole 109 and is tightened, the Velcro 110 is used to stick and fix the compression tensioning belt 104 to the back plate support column 101, thereby further improving the anti-slip performance of the fixing device 1, thereby reinforcing the vehicle equipment 3.

[0036] In some embodiments, a pull ring 108 is provided on the outer side of the backplane support column 101, and workers can operate the pull ring 108 to facilitate the transportation and disassembly of the device for fixing and monitoring the safety status of the transported vehicle.

[0037] In this embodiment, the detection device 2 includes a fiber grating strain sensor 201 and a fiber optic demodulator 202 arranged on the positive tread contact panel 103. When the running mechanism 301 contacts and squeezes the positive tread contact panel 103, the pressure on the contact surface between the running mechanism 301 and the positive tread contact panel 103 changes due to looseness or shaking of the vehicle equipment during transportation. When the fiber grating strain changes, changes in the optical signal will occur, such as drift of the central wavelength. The optical signal measured by the fiber grating strain sensor 201 is demodulated into a strain value by the fiber optic demodulator 202. The strain value data can be used to analyze the changes in the contact state and vibration state between the running mechanism 301 and the positive tread contact panel 103.

[0038] When the vehicle equipment 3 and the fixing device 1 are loose, the extrusion of the walking mechanism 301 on the positive tread contact panel 103 will be relatively weakened, and the detection device 2 will feed back the strain value to the remote monitoring system. The remote monitoring system will generate strain fluctuations (belonging to the vibration state) according to the continuously recorded strain values, and compare the real-time acquired strain value with the preset first threshold value. If the real-time strain value is less than the first threshold value, and the fluctuation amplitude of the strain fluctuation is less than the second threshold value, a warning message is generated to prompt that the vehicle equipment 3 is loose. Among them, the remote monitoring system can be a computer device, and the computer device can display the detection data received from the detection device 2 in the interface and issue a warning, such as displaying a warning message in text form in the computer interface, and / or broadcasting the warning message by voice, and / or sending a warning message to the mobile terminal used by the staff, so that the staff can be informed of the looseness of the vehicle equipment 3 in time, so as to take reinforcement measures in time. The various thresholds in this application can be set according to actual conditions and are not specifically limited.

[0039] In some embodiments, since the transportation equipment may transport multiple vehicle equipment 3 at the same time, the detection device 2 may send the identification information of the vehicle equipment together when reporting the detection data to the remote monitoring system. For example, each vehicle equipment may be numbered separately, and the vehicle number and the detection data of the vehicle may be sent to the remote monitoring system together. This allows the remote monitoring system to accurately distinguish and identify the vehicle equipment corresponding to the detection data, and can also indicate to the staff which vehicle equipment is loose in the warning message, so that the staff can take reinforcement measures efficiently and in a targeted manner.

[0040] like Figure 3 In the embodiment shown, the detection device 2 includes a unidirectional laser ranging sensor 203 fixed on the back plate support column 101, and a first laser window 105 is provided on the positive tread contact panel 103. The first laser window 105 is a laser transmission channel that penetrates the positive tread contact panel 103. The laser emitted by the unidirectional laser ranging sensor 203 passes through the first laser window 105 and irradiates the surface of the running mechanism 301 of the vehicle equipment 3, thereby measuring a first distance value, and sending the first distance value to the remote monitoring system. The first distance value data can be used to analyze the relative displacement and vibration state changes between the running mechanism 301 and the positive tread contact panel 103.

[0041] After the walking mechanism 301 is fixed in place, the first distance value should theoretically remain at a fixed value. However, considering the natural shaking during transportation, the first distance value may fluctuate slightly around the center value (i.e., the fixed value mentioned above). When the vehicle equipment becomes obviously loose or even detaches from the fixing device 1 during transportation, the first distance value will become significantly larger, that is, the first distance value changes suddenly. Therefore, a third threshold value can be set based on this. The remote monitoring system generates a displacement fluctuation (belonging to a vibration state) according to the first distance value continuously monitored and recorded, and compares the first distance value received in real time with the third threshold value. If the first distance value is greater than the third threshold value, or the amplitude of the displacement fluctuation is greater than the fourth threshold value, it is considered that there is looseness between the vehicle equipment 3 and the fixing device 1, and a warning message can be generated to prompt that the vehicle equipment 3 is loose, so that the staff can quickly take reinforcement measures. Figure 3 The embodiment uses a unidirectional laser ranging sensor that emits laser light only in the direction of the walking mechanism 301, namely, the forward laser light described in this application.

[0042] Figure 3 The detection device 2 can include a fiber grating strain sensor 201, a fiber demodulator 202 and a unidirectional laser ranging sensor 203 at the same time, so that the state information between the walking mechanism 301 and the positive tread contact panel 103 includes the strain value, the first distance value, the amplitude of the strain fluctuation and the amplitude of the displacement fluctuation. These measurement values ​​can be used to synchronously measure whether the vehicle equipment is loose, thereby improving the accuracy of state detection.

[0043] like Figure 4 The embodiment shown, with Figure 3 The difference between the embodiments is that a bidirectional laser ranging sensor 204 is used, which can not only emit forward laser to the walking mechanism 301, but also emit laser in the opposite direction of the forward laser (away from the walking mechanism 301), that is, the backward laser mentioned in the present application, and a second laser window 106 is provided on the back plate support column 101, and the second laser window 106 is a laser transmission channel that runs through the back plate support column 101.

[0044] In some embodiments, the reference coordinates can be set according to the actual transportation conditions of the transportation equipment 4, and the transportation equipment 4 can be, for example, a train or a train. Figure 5 As shown, the fixed pile 402 vertically fixed on the chassis of the transport equipment 4 can be used as a reference coordinate, and the backboard support column 101 can be directly fixed on the fixed pile 402, or the fixed pile 402 and the backboard support column 101 can be placed opposite to each other at a certain distance. When the fixing device 1 itself does not slide, the relative position relationship between the fixed pile 402 and the fixing device 1 remains unchanged.

[0045] The backward laser emitted by the bidirectional laser ranging sensor 204 is irradiated onto the fixed pile 402 through the second laser window 106, thereby measuring the second distance value, and sending the second distance value to the remote monitoring system. When the fixing device 1 does not move, the second distance value remains a fixed value. Once the fixing device 1 is loose or slides, the second distance value will change significantly. Considering the natural shaking during transportation, the second distance value may fluctuate slightly. Therefore, a preset range can be set based on this. When the second distance value is within the preset range, it is considered to be a slight fluctuation caused by natural shaking. If the second distance value exceeds the preset range, it is considered that the fixing device 1 is loose or sliding. If the fixing device 1 is fixed on the fixing pile 402, a warning message is generated to prompt that the fixing device 1 is loose, so that the staff can reinforce the fixing device 1 in time; if the fixing pile 402 and the backboard support column 101 are opposite to each other at a certain distance, a warning message is generated to prompt that the fixing device 1 slides, and the staff can perform anti-slip treatment on the fixing device in time.

[0046] In some embodiments, for a wheeled vehicle device 3, each wheel of the vehicle device 3 may be fixed separately, such as Figure 6 As shown, when a single wheel is fixed, in order to ensure that the tire is fully fixed and limited, a pair of devices for fixing and monitoring the safety status of the transported vehicle can be set at both ends of the tread. This pair of devices can share a compression tension belt 104, and the compression tension belt 104 passes through the perforations 109 on the two bottom support plates 102, tightens the compression tension belt 104, and fixes the two ends of the compression tension belt 104 to the outside of the back plate support column 101 with Velcro 110, thereby completing the fixation of the single wheel.

[0047] In some embodiments, some wheeled vehicle devices 3 may have more wheels, such as up to 6 wheels, 8 wheels, and 10 wheels, etc., so it is not necessary to follow Figure 6 The single wheels are fixed one by one in a way. Figure 7 Taking the 6-wheel vehicle equipment 3 as an example, the front sides of the first two wheels and the rear sides of the last two wheels can be fixed to form a four-vertex fixing mode, thereby ensuring the fixation of the vehicle equipment 3 while reducing the number of devices used to fix and monitor the safety status of the transported vehicle, thereby avoiding the tedious installation and disassembly under the multi-wheel structure.

[0048] In some embodiments, Figure 8An example of fixing a tracked vehicle device 3 is shown, for example, devices for fixing and monitoring the safety status of the transported vehicle can be respectively set at the four vertices of the track. It should be noted that in actual applications, the number and location of the devices for fixing and monitoring the safety status of the transported vehicle can be flexibly set according to the characteristics of the vehicle equipment such as the running mechanism type, the number of wheels and the tire distribution, and are not limited to the examples in the embodiments of the present application and the drawings.

[0049] like Fig. 9 As shown, when the transport equipment 4 transports multiple vehicle equipment 3, after the tractor head 401, the multiple vehicle equipment 3 can be loaded and fixed on the transport equipment 4 along the length direction, and a certain distance should be maintained between adjacent vehicle equipment 3. When the fixing device 1 sends a slide, the distance between two adjacent vehicle equipment 3 will be reduced. Once it is reduced to within the safe distance, it is easy to cause the two vehicle equipment 3 to collide. Therefore, the adjacent vehicle of the current vehicle equipment 3 can be used as a reference coordinate, and the backward laser emitted by the bidirectional laser ranging sensor 204 is irradiated onto the adjacent vehicle equipment 3 through the second laser window 106, so as to measure the third distance value, and send the third distance value to the remote monitoring system. The remote monitoring system compares the third distance value with the fifth threshold value set according to the safe distance. If the third distance value is less than the fifth threshold value, a warning message is generated to prompt that the two adjacent vehicle equipments are about to collide, so that the staff can adjust the distance between the vehicle equipment in time and perform anti-skid treatment for the corresponding fixing device. Fig. 9 The vehicle equipment 3 is fixed in a four-vertex form. The bidirectional laser ranging sensors 204 on the front sides of the front two wheels can detect the third distance value between the current vehicle and the previous vehicle. The bidirectional laser ranging sensors 204 on the rear sides of the last two wheels can detect the third distance value between the current vehicle and the next vehicle, thereby obtaining the third distance value between the current vehicle and the two adjacent vehicles in front and behind it. By analogy, the spacing distribution of multiple vehicle equipment on the entire transport equipment can be obtained, thereby improving the safety of vehicle transportation, eliminating misjudgments caused by the sliding and movement of the fixing device 1 itself, and improving the accuracy of status monitoring.

[0050] Figure 4 The detection device 2 can include a fiber grating strain sensor 201, a fiber demodulator 202 and a bidirectional laser ranging sensor 204 at the same time, so that the status information between the walking mechanism 301 and the positive tread contact panel 103 includes not only the strain value, the first distance value, the fluctuation amplitude of the strain fluctuation and the fluctuation amplitude of the displacement fluctuation, but also the second distance value and the third distance value. Multiple measurement values ​​and multiple parameters can be used to synchronously measure whether the vehicle equipment is loose, whether the fixing device 1 slips, and whether there is a collision risk between adjacent vehicle equipment, etc., thereby improving the accuracy of status detection and ensuring the safety of vehicle transportation.

[0051] On the basis of the above embodiments, in some embodiments, the fixing device 1 is further provided with a wireless transmission module 205, which realizes wireless communication between the detection device 2 and the remote monitoring system, and can send the strain data and distance data detected by the detection device 2 to the remote monitoring system, so that the remote monitoring system performs status analysis based on the received detection results, so as to timely identify the abnormal state of the vehicle equipment when it is fixed during transportation, and generate corresponding warning information. Since the transportation equipment 4 transports multiple vehicle equipment 3 on the whole vehicle, each vehicle equipment 3 is equipped with multiple devices for fixing and monitoring the safety status of the transported vehicle, so these devices form a wireless network through the wireless transmission module 205, forming a monitoring network of multiple sensing units, so that the safe and stable state of the entire batch of transported vehicle equipment 3 can be obtained.

[0052] In some embodiments, a power supply 206 is also fixed on the fixing device 1 to provide power for related electronic and optical components in the detection device 2 to ensure stable operation of the device for fixing and monitoring the safety status of the transported vehicle.
