Description

Technical Field

[0001] The present invention relates to the technical field of sensors, and in particular to a low-power Internet of Things vibration measurement sensor based on a 4G wireless network. Background Art

[0002] An inclination vibration measurement sensor is a sensor that can simultaneously measure the inclination angle and vibration state of an object. It usually includes two parts: an inclination sensor and a vibration sensor. The inclination sensor is used to measure the inclination angle of the object, while the vibration sensor is used to measure parameters such as the vibration frequency, amplitude, and acceleration of the object. Such sensors can be widely used in engineering fields, such as structural inclination and vibration monitoring in construction engineering, and inclination and vibration detection in mechanical equipment. Through the inclination vibration measurement sensor, users can monitor the inclination state and vibration situation of the object in real time, discover abnormal situations in time and perform corresponding processing and control, so as to ensure the safe operation of equipment and structures.

[0003] Currently, when installing such sensors, wiring is generally required for the installation location to provide power to the sensors. In some harsh installation environments, such as high-temperature, high-humidity, corrosive gas or liquid environments, the wiring operation of the sensors may become very difficult or even infeasible. These environments may cause problems such as cable aging, insulation damage or circuit short-circuit, thus affecting the normal operation of the sensors. Therefore, in such environments, the traditional wired wiring method may no longer be applicable. Based on this, in order to further improve the applicability of existing sensors, we propose a low-power Internet of Things vibration measurement sensor based on a 4G wireless network. Summary of the Invention

[0004] The purpose of the present invention is to solve the above-mentioned disadvantages in the prior art, and to propose a low-power Internet of Things vibration measurement sensor based on a 4G wireless network.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] Design a low-power Internet of Things vibration measurement sensor based on a 4G wireless network, including:

[0007] A housing, inside which a power supply component and a control component are installed;

[0008] A solar panel, disposed above the housing and electrically connected to the power supply component;

[0009] Among them, a circumferential adjustment mechanism is further provided at the top of the housing. The solar panel is connected to the circumferential adjustment mechanism through an inclination adjustment mechanism. The inclination adjustment mechanism has a first position and a second position on the circumferential adjustment mechanism. When the inclination adjustment mechanism moves from the first position to the second position, the inclination adjustment of the solar panel can be realized, and its inclination is fixed at the second position.

[0010] Furthermore, the circumferential adjustment mechanism includes a turntable. A through hole for placing the turntable is provided at the top of the housing. Among them, a locking structure is further provided between the turntable and the housing.

[0011] Furthermore, the locking structure includes a gear ring installed inside the housing. A sleeve is fixedly installed below the turntable. A plug rod is movably inserted inside the sleeve. One end of the plug rod is engaged with the gear ring. A spring is further provided between the plug rod and the sleeve.

[0012] Furthermore, the inclination adjustment mechanism includes two fixing plates fixedly installed below the solar panel. Two straight slots are provided above the turntable. The fixing plates are inserted into the straight slots. A spring ejector rod assembly is further embedded above the housing.

[0013] Among them, two limiting plates are further installed below the turntable. A guiding component is further provided between the fixing plate and the limiting plate.

[0014] Furthermore, the guiding component includes an L-shaped rod pin-connected below the fixing plate. An annular self-locking groove is provided on the end face of the limiting plate. The L-shaped rod is slidably connected in the annular self-locking groove. The lower positioning point and the upper positioning point of the L-shaped rod in the annular self-locking groove respectively form the first position and the second position.

[0015] Furthermore, a semi-gear ring is further provided on the outer side of the fixing plate. A clamping tooth is fixedly installed at the inner bottom of the housing. When the fixing plate is in the second position, the clamping tooth is engaged with the semi-gear ring.

[0016] Furthermore, a guiding groove is further provided on the outer side of the fixing plate. One end of the plug rod away from the gear ring can be inserted into the guiding groove.

[0017] Furthermore, a conductive sheet is provided in the upper inner wall of the annular self-locking groove. A conductive column is further provided below the L-shaped rod. A heating wire is embedded below the solar panel. The heating wire is electrically connected to the power supply component through the conductive sheet and the conductive column.

[0018] Further, the housing includes an upper shell and a lower cover. The upper shell and the lower cover are fastened by bolts, and a gasket is also installed between the upper shell and the lower cover.

[0019] Further, an antenna is fixedly installed on the outer side of the housing, and the antenna is electrically connected to the control component.

[0020] The low-power Internet of Things vibration measurement sensor based on 4G wireless network proposed by the present invention has the following beneficial effects: The solar panel in the present invention has the characteristics of being retractable and movable upward. This means that under harsh wiring conditions, the solar panel can be retracted when not needed to avoid damage from the external environment. At the same time, during the upward movement of the solar panel, the circumferential and tilt positions can be conveniently adjusted to ensure that the solar panel is at the best illumination angle when it rises to the proper position and is locked. This not only improves the operational convenience of the solar panel but also provides a stable long-term power supply guarantee for the power supply component.

[0021] In addition, the power supply component and the solar panel in the present invention form a closed-loop system. Through the cycle of power generation, charging, and storing electrical energy, continuous power supply to the sensor is achieved. This closed-loop system greatly improves the applicability of the sensor under harsh wiring conditions, ensures the stable operation of the sensor system, and guarantees that the system can operate efficiently in different working environments, providing reliable electrical energy support for the sensor.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0032] Refer to Figure 1-2 For an embodiment of the present invention, it discloses a low-power Internet of Things vibration measurement sensor based on a 4G wireless network. The sensor includes:

[0033] A housing 1, inside which a power supply component 11 and a control component 12 are installed. Among them, the control component 12 includes a circuit board and a plurality of sensor chips arranged on the circuit board. The plurality of chips are used to detect the inclination angle and vibration of the housing 1. It should be noted that in this embodiment, a card slot is also provided on the control component 12 for inserting a 4G data card, so as to facilitate the wireless interconnection between the control component 12 and the terminal device, so that the user can remotely master the detection information of the current sensor. These means are all prior arts and will not be elaborated here;

[0034] And a solar panel 2, which is arranged above the housing 1 and is electrically connected to the power supply component 11. Through the design of the solar panel 2, the battery life of the entire sensor can be improved outdoors, so there is no need to operate with an external power supply, which greatly improves the applicability of the present sensor in a harsh installation environment;

[0035] Among them, a circumferential adjustment mechanism 3 is further provided on the top of the housing 1. The solar panel 2 is connected to the circumferential adjustment mechanism 3 through an inclination angle adjustment mechanism 4. The inclination angle adjustment mechanism 4 has a first position and a second position on the circumferential adjustment mechanism 3. When the inclination angle adjustment mechanism 4 moves from the first position to the second position, the inclination angle of the solar panel 2 can be adjusted, and its inclination angle can be fixed at the second position.

[0036] Refer to Figure 3 , 4, 6. In some embodiments, the circumferential adjustment mechanism 3 in the present invention includes a turntable 31. A through hole for placing the turntable 31 is provided at the top of the housing 1, and the turntable 31 is rotatably connected inside the through hole. Among them, a locking structure is further provided between the turntable 31 and the housing 1, and this locking structure is used to lock and fix the circumferential position between the turntable 31 and the housing 1 to ensure that the solar panel 2 is in a fixed circumferential position.

[0037] Refer to Figure 5 , preferably, in this embodiment, the locking structure includes a gear ring 32 installed inside the housing 1. The gear ring 32 is sleeved outside the turntable 31. A sleeve 33 is fixedly installed below the turntable 31, and a plug rod 34 is movably inserted inside the sleeve 33. Among them, one end of the plug rod 34 is spiked, and one end of the plug rod 34 is engaged with the gear ring 32. Of course, the specific shape of the plug rod 34 can be adaptively set by those skilled in the art. A spring 35 is further provided between the plug rod 34 and the sleeve 33. It should be noted that the spring 35 in the present invention provides a reaction force, that is, when the spring 35 is in a compressed state, the end of the plug rod 34 is engaged with the gear ring 32, and when the spring 35 is at its free length, the end of the plug rod 34 is separated from the gear ring 32. The purpose of this design will be described in detail later and will not be elaborated here too much.

[0038] Refer to Figure 7 , 8 , on the basis of the above embodiment, the inclination adjustment mechanism 4 in the present invention includes two fixing plates 41 fixedly installed below the solar panel 2. Two one-word slots 36 are provided above the turntable 31, and the fixing plates 41 are inserted into the one-word slots 36. The two fixing plates 41 can be inserted and moved along the one-word slots 36 and can rotate in the one-word slots 36. In addition, in order to provide a supporting force for the solar panel 2, a spring ejector rod assembly 37 is further embedded above the housing 1 in the present invention. Specifically, the spring ejector rod assembly 37 includes a spring and an ejector rod. The ejector rod contacts the back of the solar panel 2. When the solar panel 2 is in the storage position, at this time the ejector rod squeezes the spring to store energy. When the solar panel 2 moves upward, the ejector rod can push the solar panel 2 upward;

[0039] Among them, two limiting plates 42 are further installed below the turntable 31, and a guiding component is further provided between the fixing plate 41 and the limiting plate 42.

[0040] Refer to Figure 8, Specifically, in the present invention, the guiding component includes an L-shaped rod 43 pin-connected below the fixing plate 41. The L-shaped rod 43 can be set as a rubber rod to facilitate providing an up-and-down deformation force. On the end face of the limiting plate 42, there is an annular self-locking groove 44. The annular self-locking groove 44 is an annular groove with multiple step positions inside, which has an upper positioning point and a lower positioning point. Specifically, the locking groove structure of the TF card socket can be referred to. This structure is prior art and will not be elaborated here. The L-shaped rod 43 is slidably connected in the annular self-locking groove 44. The lower positioning point and the upper positioning point of the L-shaped rod 43 in the annular self-locking groove 44 respectively form the first position and the second position.

[0041] That is to say, in the present invention, in the initial state, the solar panel 2 fits on the top of the housing 1. After the whole sensor is completed, press down the above-mentioned solar panel 2. At this time, the fixing plate 41 drives the L-shaped rod 43 to move in the annular self-locking groove 44. Thereafter, under the push of the spring ejector rod assembly 37, the L-shaped rod 43 moves from the lower positioning point to the upper positioning point of the annular self-locking groove 44, causing the solar panel 2 to move upward to generate a certain gap with the housing 1. Since the L-shaped rod 43 and the fixing plate 41 are pin-connected, the angle of the solar panel 2 can be adjusted during the upward movement. Coupled with the angle adjustment of the above-mentioned turntable 31, the solar panel 2 is in the best illumination angle to provide a stable long-term power supply guarantee for the power supply component 11.

[0042] Of course, after the adjustment is completed, it is also necessary to consider fixing the angle of the solar panel 2. On the outer side of the fixing plate 41 in the present invention, there is also a semi-tooth ring 45. A tooth 46 is fixedly installed at the inner bottom of the housing 1. When the fixing plate 41 is in the second position, the tooth 46 is engaged with the semi-tooth ring 45, that is, when the L-shaped rod 43 moves to the upper positioning point, the solar panel 2 reaches the maximum rising height. During this process, the user can pre-adjust the angle of the solar panel 2 in advance. When the solar panel 2 rises to the maximum height, the semi-tooth ring 45 on the side of the fixing plate 41 is engaged with the tooth 46, so that the position of the fixing plate 41 can be locked to achieve the effect of fixing the angle of the solar panel 2.

[0043] Refer to Figure 8, It should be noted that, on the basis of the above embodiments, in the present invention, a guiding groove is further formed on the outer side of the fixing plate 41, and the end of the insertion rod 34 away from the gear ring 32 can be inserted into the guiding groove. In summary, since the above spring 55 is of a reverse-pushing design, in the initial state, the end of the insertion rod 34 can always abut against one side of the fixing plate 41. At this time, the insertion rod 34 is restricted by the fixing plate 41, and its end contacts the gear ring 32. When the fixing plate 41 moves upward, one end of the insertion rod 34 can slide into the guiding groove, that is to say, at this time, the insertion rod 34 retracts and separates from the gear ring 32, and the turntable 31 is in a freely rotatable state. At this time, the circumferential angle of the solar panel 2 can be adjusted. At the same time, since the semi-tooth ring 45 is engaged with the engaging teeth 46 at this time, the inclination angle of the solar panel 2 can also be freely adjusted. In this way, the circumferential and inclination angles of the solar panel 2 are synchronously adjusted in one action, greatly improving the convenience of adjustment. After that, when the fixing plate 41 continues to rise, the insertion rod 34 is ejected from the inside of the guiding groove, and its end is engaged with the gear ring 32 again to complete the circumferential locking, and at the same time, the semi-tooth ring 45 is engaged with the engaging teeth 46 to complete the inclination locking.

[0044] Referring to Figure 8 , In addition, in the present invention, a conductive sheet 47 is provided on the upper inner wall above the annular self-locking groove 44, and a conductive column is further provided below the L-shaped rod 43. At least part of the conductive column protrudes below the L-shaped rod 43. A heating wire 21 is embedded below the solar panel 2, and the heating wire 21 is electrically connected to the power supply assembly 11 through the conductive sheet 47 and the conductive column. When encountering heavy snow weather, snow will accumulate on the upper end of the solar panel 2. Affected by gravity, at this time, the solar panel 2 will move downward a small distance. At this time, the conductive sheet 47 contacts the conductive column to conduct electricity, so as to turn on the heating wire 21 to heat the bottom of the solar panel 2 and melt the accumulated snow.

[0045] Furthermore, in the present invention, the housing 1 includes an upper housing 13 and a lower cover 14. The upper housing 13 and the lower cover 14 are fastened by bolts, and a sealing gasket 15 is also installed between the upper housing 13 and the lower cover 14.

[0046] Referring to Figure 1 、 2 , In addition, an antenna 16 is fixedly installed on the outer side of the housing 1. The antenna 16 is electrically connected to the control component 12. The design of the antenna 16 can enhance the 4G network signal to ensure the connection between the sensor and the server.

[0047] In summary, the solar panel 2 in the present invention has the characteristics of being retractable and movable upward, which means that under harsh wiring conditions, the solar panel 2 can be retracted when not needed to avoid damage from the external environment. At the same time, during the upward movement of the solar panel 2, convenient adjustment of the circumferential and inclination positions can be carried out to ensure that the solar panel 2 is at the optimal illumination angle when it rises in place and is locked. This not only improves the operability of the solar panel but also provides a stable long-term power supply guarantee for the power supply component 11.

[0048] In addition, the power supply component 11 and the solar panel 2 in the present invention form a closed-loop system. Through the cycle of power generation, charging, and storing electrical energy, continuous power supply to the sensor is achieved. This closed-loop system greatly improves the applicability of the sensor under harsh wiring conditions, ensures the stable operation of the sensor system, and guarantees that the system can operate efficiently in different working environments, providing reliable electrical energy support for the sensor.

[0049] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, should be covered by the protection scope of the present invention.
