Description

Technical Field

[0001] The present invention relates to the technical field of anti-slip fasteners, and in particular to a fastener intelligent component and a fastener. Background Art

[0002] Railway freight car anti-slip fasteners are key devices to ensure railway freight safety. They are mainly used to prevent freight cars from accidentally slipping due to wind, inertia or gravity during shunting, loading and unloading or docking.

[0003] After the installation of ordinary fasteners, it is impossible to confirm whether the locking is reliable, and it is impossible to judge whether the vehicle has slipped. The only way to judge whether the vehicle has slipped is to rely on the staff to regularly check whether the fasteners are damaged, which greatly reduces work efficiency and increases the workload of operators. Summary of the Invention

[0004] The object of the present invention is to overcome the deficiencies of the prior art and to provide a fastener smart component and a fastener, wherein the fastener smart component can transmit the detected tension result back, eliminating the need for personnel to check the status of the fasteners one by one.

[0005] The object of the present invention is achieved through the following technical solutions: In a first aspect, the present application discloses a fastener intelligent assembly, comprising a battery, a tension sensor disposed at any position in the force-bearing direction of the fastener, and a main control board electrically connected to the tension sensor.

[0006] The battery supplies power to the tension sensor and the main control board. The tension sensor periodically obtains the tension of the fastener and generates a first signal according to a preset interval. The main control board is provided with a processing module and a communication module. The processing module obtains the first signal and sends it to the control center through the communication module.

[0007] The advantage is that the tension sensor transmits the collected first signal via a data line to the processing module. The processing module interprets the first signal as corresponding tension data, or determines whether the tension is normal, and then transmits it to the control center via the communication module. This eliminates the need for on-site personnel to individually inspect each fastener. Instead, the control center manages multiple fasteners in a unified manner, which is more efficient and less prone to errors. Furthermore, periodically obtaining the tension of each fastener at intervals reduces the amount of data required for processing.

[0008] Furthermore, one or more of the tension sensor, the processing module and the communication module periodically switches between the working mode and the sleep mode; wherein the processing module is used to perform the switching between the working mode and the sleep mode.

[0009] Furthermore, the processing module is used to execute a first switching mode, including: the processing module periodically switches one or more of the tension sensor, processing module and communication module to the working mode according to a preset interval time, and during the interval time, one or more of the tension sensor, processing module and communication module is in a sleep mode.

[0010] Furthermore, the communication module includes at least one sub-module, which transmits the tension data to the control center through a relay device, and the sub-module is a short-range communication module; the processing module is used to execute a second switching mode, including: after receiving a wake-up signal regularly sent to the processing module by the relay device according to a preset interval time, the processing module regularly switches one or more of the tension sensor, processing module and communication module to the working mode, and during the interval time, one or more of the tension sensor, processing module and communication module are in a sleep mode.

[0011] Furthermore, an acceleration sensor is included. When the acceleration sensor senses displacement, it sends a signal to the processing module. The processing module switches one or more of the tension sensor, the processing module and the communication module to the working mode.

[0012] Furthermore, it also includes an electronic tag, which is arranged on the fixing claw body.

[0013] Furthermore, the battery is provided with a contact charging port and a manual charging port. The battery is a column, and the contact charging port is provided on the peripheral side of the column of the battery.

[0014] Furthermore, a satellite positioning module is also provided on the main control board.

[0015] In a second aspect, the present application discloses a fastener, comprising: the above-mentioned fastener smart component, a fixing claw, and a screw, wherein the fastener smart component is arranged on the fixing claw.

[0016] The result is that installing the fastener smart module on the fixed claw reduces space usage, preserving the classic fastener structure and retaining existing usage and storage methods. This effectively avoids signal degradation caused by obstructions from the locomotive itself, thereby establishing effective communication between the fastener smart module and the control center. Furthermore, the fastener smart module's ability to intermittently enter sleep mode to reduce energy consumption ensures long-range operation while minimizing battery size.

[0017] Furthermore, the fixing claw includes a first plate and a second plate arranged opposite to each other, the first plate extends a first claw, the second plate extends a second claw, a fastener smart component is arranged between the first plate and the second plate, and the first claw and the second claw both extend beyond the area where the fastener smart component is located.

DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention.

[0021] according to Figures 1-6 , understand the fastener smart assembly 100 and the fastener 200 according to the embodiments of the present application.

[0022] According to the fastener smart assembly 100 in the embodiment of the present application, it is used to be installed on the fastener 200. The fastener 200 can be any existing anti-slip fastener 200 used in railways.

[0023] by Figure 1 Taking the structure shown as an example, the fastener smart assembly 100 includes a battery 110 , a tension sensor 120 disposed at any position in the load-bearing direction of the fastener 200 , and a main control board 130 electrically connected to the tension sensor 120 .

[0024] The force bearing direction of the aforementioned fastener 200 is any part of the fastener 200 between the fixing claw 210 fixed to the outside of the vehicle body and the hook 221 fixed to the inside of the vehicle body (such as a chain) that can detect the tensile force in the axial direction. Figure 4 For example, the tension sensor 120 is disposed between the fixing claw 210 and the screw 220 . For another example, the tension sensor 120 is disposed between the hook 221 and the screw 220 .

[0025] In this way, the tension sensor 120 can periodically obtain the tension of the fastener 200 and generate a series of first signals according to a preset interval. In this embodiment, the first signal obtained by the tension sensor is an analog signal.

[0026] Battery 110 is preferably a wide-temperature battery 110, capable of operating normally in ambient temperatures ranging from -40°C to 80°C, meeting product usage requirements in extreme environments such as severe cold and extreme heat nationwide. Of course, in special circumstances, an external power source can be connected to battery 110 to power the entire fastener intelligent assembly 100. Therefore, without changing the core content of this application, simply replacing battery 110 with an external power source would also constitute an equivalent replacement method according to this embodiment.

[0027] like Figure 2 As shown, the main control board 130 is a PCB circuit board, which is equipped with a processing module and a communication module. The processing module obtains the tension data from the tension sensor 120, and the communication module transmits the tension data to the control center. Therefore, the fastener intelligent assembly 100 of the present embodiment can directly transmit the detected tension results back to the control center, eliminating the need for personnel to check the status of each fastener 200 one by one.

[0028] Specifically, the tension sensor 120 may be as follows: Figure 6 It is worth mentioning that if a component for detecting pressure is used to indirectly detect tension, although it is called a pressure sensor, it is still an equivalent replacement for the tension sensor 120 and should also fall within the scope of protection of this application.

[0029] The processing module in this embodiment can be any electronic component, such as a chip or single-chip microcomputer, that has digital-to-analog conversion and data processing capabilities, or an integration of multiple electronic components. For example, the processing module is a single-chip microcomputer that acquires the first information and then performs digital-to-analog conversion, converting the first signal into a digital signal for further processing. For ease of description, the processed first signal will be defined as tension data.

[0030] That is to say, the tension sensor 120 will obtain the first signal of the tension sensor, and then transmit it to the processing module through the data line. The processing module converts the first signal (such as an analog signal) into tension data (such as a digital signal), and then sends it to the control center through the communication module.

[0031] Specifically, the tension sensor periodically detects the tension in the fastener at preset intervals and generates a series of first signals, which are then periodically transmitted to the processing module for processing. The processing module compares each acquired tension data with the previous tension data. If the difference exceeds a preset threshold or falls below a specified value, it indicates that the fastener may have slipped. This eliminates the need for the fastener smart assembly 100 to continuously transmit signals, reducing overall power consumption and improving battery life.

[0032] Based on the detection of the tension sensor in the above embodiment, the tension data is processed by the processing module and sent by the communication module. After the fastener 200 is set, there is no need for personnel to go to the site to check the fastener 200 one by one. Instead, multiple fasteners 200 are managed uniformly through the control center, which is more efficient and less prone to errors.

[0033] In some examples, the processing module itself can back up data to prevent data loss, and a timed transmission signal can be set. For example, data is sent to the control center based on the communication module every 20 seconds to avoid data omissions. Of course, the specific interval time can be adjusted according to the actual application scenario.

[0034] It's worth noting that the processing module's continuous acquisition and processing of tension data requires acquiring a series of first signals from the tension sensor 120. During this process, the battery 110 must power the tension sensor 120. Similarly, the communication module and processing module also consume a certain amount of power during operation. Continuously powering these components from the battery 110 would affect the battery life of the fastener smart assembly 100.

[0035] To this end, based on the above embodiments, the subsequent embodiments provide an exemplary description of how to periodically obtain the tension of the fastener and generate a series of first signals according to a preset interval time, thereby periodically transmitting the first signals to the processing module for processing.

[0036] One or more of the tension sensor 120 , the processing module, and the communication module are switched between a working mode and a sleep mode; wherein the processing module is configured to execute the switching between the working mode and the sleep mode.

[0037] For example, the tension sensor 120, processing module, and communication module can all switch between a sleep mode and an active mode. Specifically, during the initial startup phase of the fastener smart assembly 100, the tension sensor 120, processing module, and communication module are all in active mode, continuously acquiring a series of tension data and comparing the previous and subsequent tension data. If the comparison result shows a substantially constant tension, it indicates that the fastener is functioning properly. At this point, the tension sensor 120, processing module, and communication module can periodically switch between a sleep mode and an active state, where the duration of the sleep mode can be the interval described in the aforementioned embodiment.

[0038] It should be noted that the sleep mode of the embodiment of the present application is used to save energy, so it can be directly powered off or switched to a low-power form; for example, the tension sensor 120 can be powered off to put it in sleep mode, and the processing module can be switched to a low-power mode to put it in sleep mode.

[0039] It is worth mentioning that, based on the understanding of the technical solution of putting the force sensor 120, the processing module and the communication module into sleep mode, those skilled in the art can think of a technical solution of switching the modes of other related components, such as stopping the power supply to the indicator light 132, etc. Such solutions should also fall within the scope of protection of this application.

[0040] In other words, the fastener smart assembly 100 in this embodiment is not always in operation, but rather intermittently switches to sleep mode to reduce power consumption. Therefore, when each component is in sleep mode, the battery 110 can only power the modules that maintain the lowest power consumption of the fastener smart assembly 100, thereby maximizing battery life.

[0041] In some embodiments, a readable medium (such as a program) is stored on the processing module for executing a first switching mode and a second switching mode, thereby switching between a sleep mode and a working mode through the first switching mode and the second switching mode; of course, in some examples, only the first switching mode or the second switching mode may be executed.

[0042] Next, the first switching mode and the second switching mode are described in detail.

[0043] In some embodiments, the processing module is used to execute a first switching mode, including the processing module periodically switching one or more of the tension sensor 120, the processing module, and the communication module to a working mode according to a preset interval time, and during the interval time, the tension sensor 120, the processing module, and one or more of the communication module are in a sleep mode.

[0044] For example, the case where the processing module is a single-chip microcomputer and the communication module is a 4G communication module is used for explanation. The single-chip microcomputer periodically switches between a low-power mode (i.e., a sleep mode) and a normal working mode, and the time interval between the two normal working modes is the aforementioned interval time; similarly, the single-chip microcomputer wakes up the tension sensor 120 and the communication module every time an interval time passes. When the tension sensor 120 is in sleep mode, the single-chip microcomputer controls to cut off its power. When the communication module is a 4G communication module, it is also powered off in sleep mode.

[0045] The above-mentioned 4G communication module is used as the communication module, which is suitable for some scenarios where tension data needs to be transmitted over long distances without relaying, or where the communication module needs to communicate directly with the control center.

[0046] In some examples, the communication module includes a sub-module, which transmits tension data to a control center through a relay device, and the sub-module is a short-range communication module; the processing module is used to execute a second switching mode, including: after receiving a wake-up signal periodically sent by the relay device to the processing module according to the preset interval time, the processing module periodically switches one or more of the tension sensor, processing module, and communication module to a working mode, and during the interval time, one or more of the tension sensor, processing module, and communication module are in a sleep mode.

[0047] In detail, the processing module executes the second switching mode after receiving the wake-up signal, that is, the wake-up signal can be first transmitted to the processing module through the sub-module. It is worth noting that the sub-module can be a Bluetooth / Star Flash communication module. After the Bluetooth / Star Flash communication module switches to sleep mode, it is in low power mode, so the wake-up signal can be sent to the processing module. After receiving the wake-up signal, the processing module wakes up the tension sensor 120 and other components to stop the sleep mode. For example, the relay device can regularly wake up the tension sensor 120 or the tension sensor 120 and other modules according to a preset interval time, for example, once every 30 minutes.

[0048] Here, the relay device can be any device used to realize relay communication. For example, the anti-slip iron shoes in the railway can be used as relay devices for communication, that is, a communication device is set on the anti-slip iron shoes for relay communication. Compared with the previous example, although this example needs to send data through the relay device, the power consumption required by the second communication module with a shorter communication distance is lower.

[0049] Specifically, for relatively long-distance transmission, the submodule uses Starflash, meaning the relay device and submodule are paired with Starflash. For closer-range communication, the submodule can use Bluetooth. Compared to 4G communication modules, Starflash / Bluetooth consumes less energy and can receive signals in low-power mode, enabling external devices (relay devices) to wake up internal devices (such as processors).

[0050] In some examples, the submodule can switch between Bluetooth / StarFlash and 4G communication modules to select different communication methods according to different situations. In addition, Bluetooth / StarFlash technology can be used to automatically pair the fastener 200 and the relay device, eliminating the need for manual operation at any time and anywhere.

[0051] Of course, the above submodules and the 4G communication module can be set in the communication module to select different communication modes according to different working conditions.

[0052] Based on any of the above examples, under normal conditions, that is, the tension change does not exceed the preset threshold value or is not less than the specified value, the processing module normally executes the first switching mode or the second switching mode; if it is detected that the tension change exceeds the preset threshold value or is less than the specified value, the processing module will stop the first switching mode and / or the second switching mode, but will send the tension data multiple times and keep retrying until the abnormal situation is successfully reported.

[0053] Moreover, after the 4G communication module is connected to the 4G base station, or when Bluetooth / Star Flash is matched to the relay device or data transmission is performed directly, the indicator light 132 will flash quickly to make a corresponding display. Compared with the prior art, in order to realize the automatic detection of the tension of the fastener 200 and to confirm whether the locking state of the fastener 200 is reliable, a tension sensor 120 will be set on the fastener 200 and connected to the indicator light 132. The indicator light 132 is used to determine whether the tension of the fastener 200 is abnormal, and personnel still need to check one by one. The indicator light 132 in the embodiment of the present application is not used to judge faults. The fastener intelligent component 100 in this embodiment does not require manual inspection to check whether the display lights are normal one by one, but directly checks whether there are any abnormalities in the control center.

[0054] Based on the above embodiment, although the power consumption of the fastener smart component 100 can be reduced by putting the tension sensor 120, or putting the tension sensor 120 and some other electronic components into hibernation, if the vehicle slips or other situations occur during the hibernation period of the tension sensor 120, since the tension sensor 120 is in hibernation mode, the fastener smart component 100 cannot promptly transmit fault information or abnormal tension information back to the control center, resulting in information delay.

[0055] To this end, in some examples, continue to refer to Figure 2 As shown, the fastener smart component 100 further includes an acceleration sensor 131, an exemplary acceleration sensor 131 being a G-sensor. The acceleration sensor 131 can be provided on the fastener smart component 100, for example, on the housing 140, or on other parts of the fastener 200, and then electrically connected to the main control board 130. Or as shown in FIG. Figure 2 As shown in FIG, the acceleration sensor 131 is directly mounted on the main control board 130, thereby synchronizing movement with the fastener smart assembly 100. When the acceleration sensor senses displacement, it sends a signal to the processing module, which switches one or more of the tension sensor, processing module, and communication module to an operating mode.

[0056] by Figure 2 For example, when a locomotive experiences an abnormal situation such as slipping, the fastener 200 installed on the locomotive will move synchronously due to the movement or shaking of the locomotive. At this time, the fastener smart component 100 moves synchronously, and the acceleration sensor 131 (such as a G-sensor) senses the displacement and sends a signal to the processing module to trigger the processing module to wake up the tension sensor 120 to stop the sleep mode, and then send the current tension data to the control center.

[0057] In different examples, the method for triggering the processing module to wake up the tension sensor 120 can vary. For example, the processing module can store a third switching mode compatible with the first and second switching modes, so that the processing module wakes up the tension sensor 120 after receiving a signal indicating movement from the acceleration sensor 131. Alternatively, the processing module can receive the second switching mode in a manner compatible with the signal sent by the acceleration sensor 131, i.e., the tension sensor 120 wakes up based on the second switching mode after receiving the signal sent by the acceleration sensor 131.

[0058] Therefore, the movement of the fastener intelligent component 100 is detected in real time through the acceleration sensor 131, and the wake-up mechanism is triggered when movement occurs. While maintaining low energy consumption of the fastener intelligent component 100, when the locomotive has abnormal conditions such as slipping, the tension data can be sent to the control center in time, thereby realizing the real-time monitoring function of each fastener 200.

[0059] The fastener smart assembly 100 in each of the above-described embodiments achieves intermittent sleep through different switching modes, significantly reducing the power consumption of the fastener smart assembly 100. This further reduces the space required for the fastener 200. In other words, when the fastener smart assembly 100 itself is relatively small, the space available for its placement is limited, and the battery 110 is even smaller, resulting in a weaker energy storage capacity. The fastener smart assembly 100 in the above-described embodiments can meet the battery life requirements.

[0060] In order to illustrate the above effects, a fastener 200 will be described in conjunction with an example. Here, in order to make the reading more coherent, the fastener smart component 100 will be described in conjunction with the example.

[0061] In some embodiments, the fastener smart assembly 100 may be further referred to Figure 2-Figure 3 As shown, it also includes: a shell 140 and a cover plate 150 , and the open side cover plate 150 of the shell 140 cooperates to form a closed space for arranging the main control board 130 and the battery 110 .

[0062] refer to Figure 3 As shown, the battery 110 is a cylinder with a rounded rectangular cross section. The flat side of the cylinder surface of the battery 110 is provided with a contact charging port 111, and the end is provided with a manual charging port 112. The contact charging port 111 can be Figure 3 The double contact structure shown in FIG, the manual charging port 112 can be Figure 3 The TYPE-C manual charging port 112 shown in FIG.

[0063] In this way, the fastener 200 equipped with the fastener smart component 100 can be quickly charged through the contact charging port 111, or the fastener smart component 100 can be quickly charged after being removed from the fastener 200. For example, when the fastener 200 is returned to the tool box, the automatic contact charging port 111 located on the side wall of the battery 110 contacts the charging device set in the tool box, thereby automatically charging the battery 110. In this way, the fastener 200 is automatically charged after being placed in the cabinet. The operator only needs to put the fastener 200 back to the corresponding position in the tool box to automatically charge, without the need for unnecessary steps such as manual plugging, thus saving time and effort. If the fastener 200 cannot be returned to the tool box for charging due to long-term operation, a mobile power supply (such as a power bank) can be used to charge the battery 110 through the manual charging port 112 (such as TYPE-C).

[0064] In some embodiments, an RFID electronic tag is provided on the partition 13. When the fastener 200 is put back into the tool box, the tool box RFID identification module can read the unique identification of the fastener 200 in real time, thereby realizing real-time supervision of the status of each fastener 200 in the cabinet.

[0065] In some embodiments, a satellite positioning module is also provided on the main control board 130 so that GNSS multi-star full-frequency coordinated RTK differential positioning can accurately locate the position of the fastener 200 with an accuracy of centimeters, providing protection in real-time monitoring, safety, and anti-theft.

[0066] Next, combine Figure 4-Figure 6 A fastener 200 according to an embodiment of the present application includes a fixing claw 210 and a screw 220, with a hook 221 disposed at the end of the screw 220. The fastener smart assembly 100 described in the above embodiment is disposed on the fixing claw 210. The fixing claw 210 is used to secure the fastener 200 to a train, and the hook 221 is used to hook an iron chain at the bottom of the train. The iron chain is tightened by the fastener 200 to brake the train. A nut 222 is threadedly connected to the screw 220, and the nut 222 is connected to the fixing claw 210 via a rotating shaft, thereby connecting to the fixing claw 210 via the nut 222.

[0067] refer to Figure 5 As shown, one side of the fixing claw 210 is provided with a claw 211 for fastening to the train carriage, and the other side is provided with a slot 212 for installing the fastener smart component 100. Figure 6As shown, a cavity 2221 is constructed within the nut 222, and a tension sensor 120 is disposed within this cavity 2221. Specifically, the tension sensor 120 comprises one or more strain gauges fitted to the inner wall of the cavity 2221, which are used to detect the tension exerted on the nut 222 along its axis. A wiring groove 213 is provided on the fixed claw 210. The strain gauges are connected to the main control board 130 via wiring 300, which is embedded within the wiring groove 213. This not only improves the overall aesthetics of the fixed claw, but also prevents damage to the cable caused by impact during use, thereby extending its service life.

[0068] Specifically, the nut 222 is threadedly connected to the screw rod 220 and is connected to the fixed claw 210 through a rotating shaft. When the fastener 200 is tightened, the strain gauge can sense the deformation of its own structure and transmit an electrical signal to the main control board 130 through the line 300. This electrical signal is the first signal. The subsequent processing of the first signal by the main control board 130 is the same as in the above embodiment and will not be repeated here.

[0069] It is understandable that since the fastener smart assembly 100 itself occupies a certain volume, if it were directly mounted on the screw 220 or other areas of the fastener 200, the overall volume of the fastener 200 would increase, occupying more space. This would make it difficult to store it in existing anti-slip boxes, necessitating the manufacture of a matching anti-slip box, increasing costs. However, by utilizing the larger volume of the fixing claw 210 to define a groove 212 within the fixing claw 210, thereby creating a sufficient clearance for mounting the fastener smart assembly 100, the space occupied can be reduced without changing existing usage and storage methods.

[0070] Furthermore, in actual use, the hook 221 and screw 220 in the fastener 200 are fixed to the underside of the vehicle body, meaning they need to be secured to the chain underneath the vehicle body; while the fixing claw 210 is fixed to the outside of the vehicle body, meaning it needs to be fixed to the ribs on the side of the motorcycle. Therefore, the hook 221 and screw 220 in the fastener 200 are located in the narrow area below the motorcycle. Furthermore, the motorcycle itself is made of metal, creating a signal shielding area underneath the motorcycle. Placing the fastener smart component 100 near the screw 220 or hook 221 will weaken the signal.

[0071] Therefore, placing the fastener smart component 100 with communication function in the fixing claw 210 located on the outside of the vehicle body can effectively avoid the problem of signal weakening due to the obstruction of the locomotive itself, thereby establishing an effective communication connection between the fastener smart component 100 and the control center.

[0072] It is worth mentioning that in the case where the fastener smart component 100 is shielded, the aforementioned second switching mode can be adopted, that is, a Bluetooth / Star Flash relay device is placed near the fastener 200 to relay the fastener 200 status data back to the control center.

[0073] As mentioned above, in order to improve the communication effect, the fastener 200 in the embodiment of the present application sets the fastener smart component 100 in the fixed claw 210. However, the fixed claw 210 is limited in size after all, which limits the volume of the battery 110 in the fastener smart component 100. If energy-saving measures are not taken, the power will be exhausted quickly. In other words, when the fastener smart component 100 described in the above embodiment is used, when the smart fastener component 100 itself is small in size, the space available for arranging the battery is limited, resulting in a small volume of the battery 110 and a weak energy storage capacity. Figure 4-Figure 5 A specific fastener structure is shown for understanding.

[0074] The fixing claw 210 includes a first plate 11 and a second plate 12 that are arranged opposite to each other, a first claw 2111 extending from the first plate 11, and a second claw 2112 extending from the second plate 12. A partition 13 is connected between the first plate 11 and the second plate 12, and the partition 13 and the first plate 11 and the second plate 12 jointly define a groove body 212. The fastener smart component 100 is arranged in the groove body 212, and the first claw 2111 and the second claw 2112 both extend beyond the area where the fastener smart component 100 is located.

[0075] In this way, the fastener smart component 100 in the above embodiment is set in the fixing claw 210.
