Description

Technical Field

[0001] The present invention relates to the field of monitoring technology, and in particular to a dynamic real-time adjustable Internet of Things monitoring device and method based on the MQTT protocol. Background Art

[0002] The MQTT protocol is widely used in IoT monitoring and has become the de facto standard for IoT communications due to its lightweight, low power consumption, low bandwidth consumption, and high reliability. It enables efficient communication between devices and servers through a publish / subscribe model and supports tiered QoS to ensure reliable data transmission, making it particularly suitable for resource-constrained IoT devices and network environments.

[0003] However, IoT monitoring devices often face stability issues in practical applications. This is especially true in complex environments with high vibration and wind, such as those found on vehicles and in factories. Traditional fixed support systems cannot effectively cope with external fluctuations, resulting in unstable equipment installations and impacting monitoring effectiveness. Prolonged exposure to vibration can even damage the fixtures.

[0004] While existing technologies use buffer components to absorb vibration and wind, this flexible buffering force can cause the device to deflect significantly when subjected to strong external forces, further compromising monitoring stability. Furthermore, when monitoring equipment deflects significantly, the elastic elements within the buffer component can become extremely compressed, causing the device to rock back and forth due to inertia during reset. This can prolong the time it takes to switch from dynamic to static mode, further compromising stability during monitoring and even damaging the buffer component. Summary of the Invention

[0005] The purpose of the present invention is to provide a dynamic real-time adjustable Internet of Things monitoring device and method based on the MQTT protocol to solve the problems raised in the above background technology.

[0012] As a further solution of the present invention, a plurality of groups of arcuate grooves are equidistantly arranged on the locking disk in a circumferential manner, and when the extension portion moves toward the outside of the rotating disk, it can abut against the side of the arcuate groove.

[0013] As a further solution of the present invention: the extension portion includes a locking member slidably installed in the sliding groove, and the locking member is connected to the inner wall of the sliding groove through a second cylindrical spring.

At the same time, this structural design does not require additional energy input, reducing the complexity and maintenance cost of the system. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0020] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0021] See also Figures 1 to 3 In an embodiment of the present invention, a dynamic real-time adjustable Internet of Things monitoring device based on the MQTT protocol includes: a monitoring device body 1, a buffer component and a centrifugal locking component.

[0022] Two pairs of traction rods 2 are rotatably mounted on the monitoring device body 1 , and a connecting plate 3 is rotatably mounted on one end of the traction rod 2 away from the monitoring device body 1 .

[0023] In this embodiment, the connecting plate 3 is fixedly mounted on an external stable support, such as the inner wall of a vehicle compartment, a building facade, or a pole with a stable base. The drawbars 2 are designed with four symmetrically spaced groups, forming a stable quadrilateral geometry with the connecting plate 3 and the monitoring device body 1. This structure guides the drawbars 2 in controlled deflection when the monitoring device body 1 is subjected to external shock or vibration. The built-in buffer assembly effectively suppresses this deflection, ensuring the stability of the monitoring device body 1 under complex operating conditions.

[0024] Among them, since the connecting plate 3, the traction rod 2 and the monitoring device body 1 together form a stable quadrilateral geometric structure, when the monitoring device body 1 shakes, its monitoring direction is constant (the height will change), so that in the monitoring state, even if the monitoring device body 1 shakes, it can still maintain the predetermined monitoring effect, avoiding the change of monitoring direction due to the deviation of the monitoring device body 1, thereby avoiding the loss of the monitoring target during the shaking process.

[0025] Furthermore, the gravity of the monitoring device body 1 itself plays an important role in the system. When the traction rod 2 deflects, the height of the monitoring device body 1 changes accordingly, and part of the external force is converted into gravitational potential energy. This design uses the weight of the monitoring device body 1 to form a natural damping effect, further suppressing the deflection amplitude of the traction rod 2 and enhancing the overall stability of the system.

[0026] Through the above-mentioned optimized design, this embodiment not only improves the stability and durability of the monitoring device, but also achieves the dual goals of structural simplification and performance improvement. The quadrilateral structure combined with the design of the buffer component can effectively absorb and disperse external impact force, significantly improving the stability of the monitoring device in a vibration or collision environment; at the same time, the gravitational potential energy conversion mechanism makes the deadweight of the monitoring device body 1 a natural damping source to suppress deflection, and dynamic balance can be achieved without additional energy input; in addition, the introduction of the buffer component reduces the direct collision of mechanical parts, effectively reduces wear and tear, and extends the service life of the equipment. This structure can be adapted to a variety of installation environments to meet the monitoring needs in different scenarios.

[0027] See also Figures 1 to 5 , the buffer assembly is connected to the traction rod 2, and the buffer assembly can slow down the vibration of the monitoring device body 1 caused by external force; the buffer assembly includes a vertical shaft 9 fixedly mounted on the connecting plate 3, and a sliding sleeve 7 is slidably mounted on the vertical shaft 9, and a connecting frame 6 is connected to the sliding sleeve 7, and one end of a first cylindrical spring 8 sleeved on the vertical shaft 9 is connected to the sliding sleeve 7; the buffer assembly also includes an adjustment structure connected to the other end of the first cylindrical spring 8 and a chimeric structure connecting the connecting frame 6 and the traction rod 2. Specifically, the chimeric structure includes an intermediate connecting rod 4 rotatably connected to the two adjacent traction rods 2, and a groove wheel 5 is rotatably mounted on the middle part of the intermediate connecting rod 4. It should be noted that the rotational connection between the intermediate connecting rod 4 and the two traction rods 2 is at the same position of the corresponding traction rod 2. At this time, the intermediate connecting rod 4, the connecting plate 3 and the two traction rods 2 can form a parallelogram structure, so that when the connecting plate 3 is ensured to be parallel to the horizontal plane after installation, the intermediate connecting rod 4 can always maintain a horizontal state.

[0028] The interlocking structure further includes a transverse groove 601 provided on the side of the connecting frame 6 , and the sheave 5 can roll in the transverse groove 601 .

[0029] In the initial state, the first cylindrical spring 8 is in a compressed state. This pre-compression design enables the sliding sleeve 7 to have a tendency to drive the connecting frame 6 to move away from the connecting plate 3. Under this tendency, the intermediate connecting rod 4 is pushed to the maximum distance away from the connecting plate 3, so that the traction rod 2 is perpendicular to the connecting plate 3. This initial design not only ensures the initial stability of the monitoring device body 1, but also provides sufficient buffer space for subsequent dynamic response.

[0030] When an external force acts on the monitoring device body 1, the monitoring device body 1 will shake and cause the traction rod 2 to deflect. At this time, the intermediate link 4 follows the movement of the traction rod 2, and the movement of the intermediate link 4 can be decomposed into two states: lateral movement and longitudinal movement. During the lateral movement, the sheave 5 can roll within the transverse groove 601, ensuring the stability of the connection between the intermediate link 4 and the connecting frame 6, thereby maintaining the overall structural integrity of the system. During the longitudinal movement, the connecting frame 6 and the sliding sleeve 7 move along the length of the vertical shaft 9 toward the connecting plate 3, further compressing the first cylindrical spring 8. At this time, the first cylindrical spring 8, while storing elastic potential energy, suppresses the rise of the intermediate link 4 through its reverse force, thereby slowing the deflection amplitude of the traction rod 2 and ultimately reducing the amplitude of the shaking of the monitoring device body 1 caused by the external force.

[0031] Through this design, the system can not only effectively absorb external impact force, but also use the elastic potential energy of the first cylindrical spring 8 to achieve dynamic balance, significantly improving the stability and reliability of the monitoring device in complex environments. At the same time, this structural design does not require additional energy input, reduces the complexity and maintenance cost of the system, and provides a guarantee for the use of the monitoring device in various application scenarios.

[0032] See also Figure 5 , wherein the adjustment structure includes a stepping motor 11 fixedly mounted on the connecting plate 3, a bidirectional screw rod 12 is connected to the output shaft of the stepping motor 11, and two groups of threaded sleeves 13 are provided on the bidirectional screw rod 12 and threadedly connected thereto, and a support rod 14 is rotatably connected to the threaded sleeve 13; the adjustment structure also includes a follower sleeve 10 slidably arranged on the vertical shaft 9 and abutting against the end of the first cylindrical spring 8, and the follower sleeve 10 is rotatably connected to the end of the support rod 14 away from the threaded sleeve 13.

[0033] During use, when the stepper motor 11 is working, the bidirectional screw 12 connected to its output shaft starts to rotate. The bidirectional screw 12 is provided with two sections of threads with opposite rotation directions (right-handed thread and left-handed thread), and two sets of threaded sleeves 13 are respectively matched with these two sections of threads. When the bidirectional screw 12 rotates, the threaded sleeves 13 can move closer to or away from each other along the length direction of the screw.

[0034] When the two groups of threaded sleeves 13 move away from each other, the support rod 14 pushes the follower sleeve 10 to move away from the connecting plate 3 along the length direction of the vertical shaft 9, thereby applying downward pressure on the upper end of the first cylindrical spring 8, changing its initial compression amount. By adjusting the initial compression amount of the first cylindrical spring 8, on the one hand, the initial stability of the monitoring device body 1 can be optimized; on the other hand, the initial elastic damping of the first cylindrical spring 8 can be adjusted according to the actual usage scenario, so that the monitoring device body 1 can obtain effective buffering under different external forces, thereby enhancing its applicability.

[0035] In order to ensure the stability of the adjustment process, a guiding structure (not shown in the figure) is provided on the connecting plate 3, which is fixedly connected to the threaded sleeve 13 to prevent the threaded sleeve 13 from rotating with the bidirectional screw 12, while providing axial guidance and locking functions. In addition, a guide block is provided on the inner wall of the follower sleeve 10, which is slidably connected to the guide groove on the vertical shaft 9 to ensure that the follower sleeve 10 is axially locked during the displacement process, thereby ensuring the stable displacement of the follower sleeve 10 when the bidirectional screw 12 rotates.

[0036] This design achieves precise adjustment of the compression amount of the first cylindrical spring 8 through the high-precision transmission of the bidirectional screw 12 and the bidirectional movement of the threaded sleeve 13, while using the guide structure and axial locking function to ensure the stability and adjustment accuracy of the system.

[0037] The above arrangement can buffer slight vibrations applied to the monitoring device body 1. In this state, the external force applied to the monitoring device body 1 is small. The elastic force provided by the first cylindrical spring 8 can buffer the above force applied to the monitoring device body 1, thereby preventing the monitoring device body 1 from vibrating or resonating, and avoiding the durability reduction of the internal components of the monitoring device body 1 due to long-term vibration, thereby ensuring the stable operation of the monitoring device body 1.

[0038] As a special case, when the external force is large, the monitoring device body 1 tends to deflect at a large angle. At this time, the first cylindrical spring 8 will be compressed to the extreme, causing a certain impact when the monitoring device body 1 moves to the maximum angle. At the same time, in this case, the monitoring device body 1 will deflect back and forth during the reset process, which increases the reset time of the monitoring device body 1 and may also damage the normal performance of the first cylindrical spring 8. To this end, the present application also provides the following structure: Please refer to Figure 6-Figure 7 The centrifugal locking assembly is connected to the rotating shaft of the traction rod 2 on the connecting plate 3 through a transmission structure; the transmission structure includes a driving wheel 15 coaxially fixedly connected to the rotating shaft of the traction rod 2 and a driven wheel 16 rotatably mounted on the connecting plate 3, and the driven wheel 16 is connected to the centrifugal locking assembly; a traction belt 17 is sleeved between the driving wheel 15 and the driven wheel 16. Specifically, a connecting plate 18 is fixedly mounted on the connecting plate 3, and the driven wheel 16 is rotatably mounted on the connecting plate 18.

[0039] When the monitoring device body 1 is shaken by an external force, the traction rod 2 can rotate relative to the connecting plate 3. At this time, the driving wheel 15 on the traction rod 2 will also rotate, and drive the driven wheel 16 to rotate through the traction belt 17. Since the circumferential radius of the driven wheel 16 is smaller than the driving wheel 15, during the operation of the traction belt 17, the driven wheel 16 has a faster rotation speed than the driving wheel 15. Based on this, when the external force acts on the monitoring device body 1 and causes it to deflect at a large angle and high speed, the driven wheel 16 can rotate at a faster speed, and the driven wheel 16, the driving wheel 15 and the traction rod 2 can be locked in time by the centrifugal locking assembly, thereby avoiding the problem of large-scale shaking of the monitoring device body 1 causing unstable monitoring and excessive reset time caused by the large-scale shaking of the monitoring device body 1.

[0040] Preferably, the traction belt 17 is preferably a toothed belt or chain structure, and the corresponding driving wheel 15 and driven wheel 16 are preferably toothed sprockets or sprockets that cooperate with the chain, so as to avoid slipping between the driven wheel 16 and the traction belt 17.

[0041] This design, through the rapid rotation of the driven wheel 16 and the timely locking of the centrifugal locking assembly, effectively improves the stability of the monitoring device body 1 when subjected to external forces, reduces the amplitude of shaking, shortens the reset time, and ensures stable and accurate monitoring. At the same time, the toothed belt or chain structure traction belt 17 and its corresponding sprocket ensure the stability and reliability of the transmission, avoid slippage, and further improve the performance and applicability of the monitoring device.

[0042] See also Figures 8 to 10 The centrifugal locking assembly is arranged on the connecting plate 3 and connected to the rotating shaft of the traction rod 2. The centrifugal locking assembly includes a locking plate 22 and an extension, and the extension can be inserted into the locking plate 22 to lock the traction rod 2; the centrifugal locking assembly also includes a rotating plate 19 rotatably mounted on the connecting plate 18, and the rotating plate 19 is coaxially fixedly connected to the driven wheel 16. The rotating plate 19 is circumferentially equidistantly provided with a plurality of groups of slide grooves 1901 arranged along its radial direction, and the extension is arranged in the slide groove 1901. When the rotating plate 19 rotates, the extension can move along the length direction of the slide groove 1901; the locking plate 22 is circumferentially equidistantly provided with a plurality of groups of arc grooves 23. When the extension moves toward the outside of the rotating plate 19, it can abut against the side of the arc groove 23.

[0043] When the traction rod 2 deflects at a large angle and high speed, the rotating disk 19 rotates at high speed. At this time, the extension portion arranged in the slide groove 1901 moves outward under the action of centrifugal force. When the extension portion is inserted into the arc groove 23 and abuts against the inner wall, the rotating disk 19 stops rotating, thereby locking the rotating disk 19, the driven wheel 16, the driving wheel 15 and the traction rod 2. This design can lock the monitoring device body 1 in time when the external force is large, avoid it from shaking significantly, and ensure the stability of the monitoring state.

[0044] In addition, the locking mechanism can also prevent the first cylindrical spring 8 from being compressed to the extreme when the monitoring device body 1 deflects at a large angle, and avoids reciprocating large-angle shaking caused by inertia during the resetting process of the monitoring device body 1, thereby further improving the stability of the monitoring device in the monitoring state. Through the locking mechanism triggered by centrifugal force, the monitoring device can remain stable in complex environments, provide reliable monitoring performance, and reduce the risk of equipment damage due to external impacts.

[0045] It should be noted that, in the initial stage when the traction rod 2 deflects at a large angle and high speed, the buffer assembly still has a buffering effect on the deflection.

[0046] See also Figures 9 to 11 The extension portion includes a locking member 20 slidably installed in the slide groove 1901, and the locking member 20 is connected to the inner wall of the slide groove 1901 through a second cylindrical spring 21; a stop portion 2301 is provided on the side wall of the arc groove 23, and an annular stop groove 2001 is provided on the extension portion, and the annular stop groove 2001 cooperates with the stop portion 2301 to prevent the extension portion from separating from the arc groove 23.

[0047] In the initial state, the second cylindrical spring 21 is in a natural state. At this time, the locking member 20 protrudes slightly from the rotating disk 19, but does not extend into the arc groove 23. When the traction rod 2 deflects at a large angle and high speed, the rotating disk 19 rotates rapidly. During this process, the locking member 20 is subjected to centrifugal force and moves toward the outside of the rotating disk 19, causing the second cylindrical spring 21 to be stretched. When the end of the locking member 20 away from the second cylindrical spring 21 abuts against the side of the arc groove 23, the annular stop groove 2001 on the locking member 20 is precisely engaged with the stop portion 2301, thereby achieving a firm locking of the rotating disk 19, the driven wheel 16, the driving wheel 15 and the traction rod 2.

[0048] This design uses centrifugal force to trigger the locking mechanism, ensuring that when the external force is large, the monitoring device body 1 can quickly enter the locked state, effectively avoiding large-scale shaking and ensuring the stability of monitoring. At the same time, the mechanism prevents the locking member 20 from resetting due to the cessation of movement of the rotating disk 19 through the engagement of the annular stop groove 2001 with the stop part 2301, thereby ensuring the stability of the locked state. This stable locked state not only reduces the reciprocating shaking of the monitoring device body 1 due to inertia during the resetting process, but also improves the reliability of the monitoring device in complex environments and extends the service life of the equipment.

[0049] Furthermore, when the external force disappears, the monitoring device body 1 will reset, and the rotating disk 19 will move in the opposite direction, so that the annular stop groove 2001 can be separated from the stop portion 2301. At this time, since the centrifugal force on the locking member 20 is small, it can be reset under the traction of the second cylindrical spring 21.

[0050] The buffer component is used to assist in buffering the small amplitude vibrations that the monitoring device body 1 is subjected to in a normal working environment. When the external force is large, the present application can reduce the deflection amplitude of the monitoring device body 1 by temporarily locking the buffer component, thereby shortening the reset time of the monitoring device body 1.

[0051] Furthermore, for this application, the most basic monitoring performance of the monitoring device body 1 should be guaranteed. When the monitoring device body 1 occasionally swings at a large angle, the stability of the monitoring device body 1 can be guaranteed by the centrifugal locking assembly.

[0052] As an embodiment of the present invention, a method for adjusting a dynamic real-time adjustable Internet of Things monitoring device based on the MQTT protocol as described above is also proposed, including: when the external force acting on the monitoring device body 1 is less than a preset value, the vibration of the monitoring device body 1 is suppressed by using a buffer component; the buffering degree of the buffer component on the monitoring device body 1 can be set by controlling the adjustment structure; when the external force acting on the monitoring device body 1 is greater than a preset value, the transmission structure drives the centrifugal locking component to operate, so that the extension part moves toward the outside and cooperates with the locking disk 22 to forcibly lock the traction rod 2.
