Description

Technical Field

[0001] This invention relates to the field of sensor technology, and more specifically, to a coal mine underground fire early warning device. Background Technology

[0002] Underground fire monitoring in coal mines is a crucial part of coal mine safety management. It mainly involves installing monitoring devices underground to collect real-time data on the concentration of indicators such as methane and carbon monoxide. If the gas concentration exceeds a preset value, an alarm will be triggered, helping workers to promptly detect and control fire hazards and ensuring the safety of mine workers.

[0003] In the prior art, for example, application number CN202111385582.6 discloses a multi-parameter sensor for mining, comprising: a common instrument and multiple sensing units. The common instrument and the multiple sensing units are separate structures, and the multiple sensing units are connected to the common instrument via wired or wireless means. All the common instrument and the multiple sensing units are located within the mine, with the multiple sensing units distributed at various monitoring points within the mine. The multiple sensing units are used for real-time monitoring of the mine environment. While this technology solves the problem of independent and unintegrated monitoring data for different environmental parameters, which to some extent makes it difficult for the sensor to effectively monitor the on-site environment, it still has certain shortcomings. For example, although this sensor can provide timely fire warnings, in actual use, it still suffers from slow response speed, complex module composition, and high maintenance costs. Summary of the Invention

[0004] The purpose of this invention is to provide a coal mine underground fire early warning device to solve the aforementioned technical problems.

[0005] The present invention solves the above-mentioned technical problems through the following technical solutions:

[0006] The present invention provides a coal mine underground fire early warning device, comprising: a multi-parameter sensor body, a hook and a suspension mechanism, wherein the hook is used to fix it at a preset monitoring position underground, and the suspension mechanism is connected to the multi-parameter sensor body and is used to connect to the hook;

[0007] The multi-parameter sensor body is equipped with a parameter acquisition module, an integrated data processing and decision-making module, a data transmission module and a power supply module.

[0008] The parameter acquisition module is used to collect data on relevant parameters required in the well and transmit the collected data to the integrated data processing and decision-making module. The parameter acquisition module includes a methane acquisition unit, a carbon dioxide acquisition unit, a carbon monoxide acquisition unit, and a temperature and humidity acquisition unit.

[0009] The integrated data processing and decision-making module is used to process data from various acquisition units, generate early warning information, control the working status of sensors, and is responsible for the transmission of some data; the integrated data processing and decision-making module includes a data monitoring and analysis unit, an early warning processing unit, a control logic unit, and a partial data transmission unit;

[0010] The data monitoring and analysis unit is used to analyze data from each acquisition unit in real time to detect whether there are any abnormalities; the early warning processing unit is used to generate corresponding early warning information based on preset thresholds and algorithms to indicate possible safety risks or abnormalities; the control logic unit is used to implement corresponding control strategies based on the early warning information to adjust the sensor's acquisition frequency and working mode; and the partial data transmission unit is used to transmit partial data to an external system so that timely countermeasures can be taken.

[0011] As a further optimization of the present invention, the suspension mechanism includes a suspension frame, an elastic body, a clamping component, and a cable winding component. The bottom end of the suspension frame is slidably connected to the outside of the multi-parameter sensor body. The elastic body is fixedly installed between the top of the multi-parameter sensor body and the upper end of the suspension frame. The clamping component is disposed at the suspension end of the suspension frame connected to the hook, and is used to lock the suspension end of the suspension frame. When the suspension frame is suspended at the bottom end of the hook, the clamping component contacts the hook. The cable winding component is disposed on one side of the multi-parameter sensor body and is used to wind the cable connected to the multi-parameter sensor body. The cable winding component is connected to the suspension frame.

[0012] When the multi-parameter sensor body needs to be calibrated or repaired, by pulling the multi-parameter sensor body downward, the clamping component is subjected to tension and moves to contact the side of the hook, so that the suspension frame and the hook are temporarily locked. The multi-parameter sensor body moves down along the locked suspension frame, and the cable winding component is synchronously driven by the suspension frame to extend the cable, so that the cable adapts to the position change of the multi-parameter sensor body.

[0013] As a further optimization of the present invention, the suspension frame includes a suspension section and two connecting sections. The suspension section is convex in shape, and the connecting sections are inverted L-shaped. The suspension section is located at the top of the multi-parameter sensor body, and its bottom end is connected to the ends of the two connecting sections respectively. The multi-parameter sensor body has symmetrically distributed sliding grooves on both sides, and the two connecting sections are slidably installed in the two sliding grooves.

[0014] As a further optimization of the present invention, the clamping component is disposed at the top of the suspension section. The clamping component includes a contact drive, a first locking component, and a second locking component. The contact drive has an elastic telescopic function and is slidably disposed at the top of the suspension section. When the multi-parameter sensor body is pulled, the contact drive causes the contact drive to retract into the suspension frame. The first locking component and the second locking component are both connected to the contact drive. When the contact drive is subjected to tension, it drives the first locking component and the second locking component to move and contact the outer side of the hook in turn, thereby locking the suspension frame in the X-axis and Y-axis directions, respectively.

[0015] As a further optimization of the present invention, the contact drive component includes a connecting rod, a contact base plate, a return spring, and a positioning knob. The connecting rod is slidably installed at the top of the suspension section, with its two ends passing through both sides of the suspension section. The contact base plate is fixedly connected to the bottom end of the connecting rod. The positioning knob is threadedly connected to the top end of the connecting rod, and its bottom end is in contact with the top surface of the suspension section.

[0016] As a further optimization of the present invention, the first locking member includes two first pressing bodies and two first movable rods. The two first pressing bodies are symmetrically distributed in the suspension section with the connecting rod as the axis of symmetry and along the X-axis. The ends of the two first pressing bodies are respectively fixedly connected to both sides of the connecting rod. The two first movable rods are symmetrically slidably installed in the suspension section, and the two first movable rods are distributed one-to-one with the two first pressing bodies. One end of the first movable rod is provided with a first inclined groove, and the bottom end of the first pressing body is slidably connected to the first inclined groove. A first connecting spring is fixedly installed between one end of the first movable rod and the inner side wall of the suspension section. The other end of the first movable rod passes through one side of the suspension section and is threaded with a first locking block.

[0017] As a further optimization of the present invention, the second locking member includes two second pressing bodies and two second movable rods. The two second pressing bodies are symmetrically distributed in the suspension section with the connecting rod as the axis of symmetry and along the Y-axis. The ends of the two second pressing bodies are respectively fixedly connected to both sides of the connecting rod. The two second movable rods are symmetrically slidably installed in the suspension section, and the two second movable rods are distributed one-to-one with the two second pressing bodies. One end of the second movable rod is provided with a second inclined groove, and the bottom end of the second pressing body is slidably connected to the second inclined groove. A second connecting spring is fixedly installed between one end of the second movable rod and the outside of the connecting rod. The other end of the second movable rod passes through one side of the suspension section and is threaded with a second locking block.

[0018] As a further optimization of the present invention, the cable winding component includes a protective housing, a winding wheel, a transmission gear, and a guide wheel. The protective housing is detachably installed on one side of the multi-parameter sensor body. The winding wheel is rotatably installed inside the protective housing, and a cable is wound around the outside of the winding wheel. The transmission gear is fixedly mounted on the shaft of the winding wheel, and a toothed groove is provided on one side of the connecting section near the protective housing. One side of the transmission gear meshes with the toothed groove. The guide wheel is located below the winding wheel, and one side of it is rotatably connected to the inner wall of the protective housing. One end of the cable passes through the guide wheel and then through one side of the protective housing. An adjustment knob is rotatably installed on one side of the protective housing, and one end of the adjustment knob is fixedly connected to one side of the winding wheel.

[0019] As a further optimization of the present invention, a fixing knob is threadedly installed at the lower end of the connecting section away from the cable winding component, and one end of the fixing knob passes through one side of the connecting section.

[0020] As a further optimization of the present invention, the suspension mechanism further includes an adjustment component, which includes a fixed plate and an adjustment rod. The two ends of the fixed plate are respectively fixedly connected to the bottom end of the suspension section, and the adjustment rod is threadedly installed in the middle of the fixed plate, with its bottom end abutting against the top of the multi-parameter sensor body.

[0021] The beneficial effects of this invention are as follows:

[0022] This invention integrates traditional early warning, control, and partial transmission functions into a single module by setting up an integrated data processing and decision-making module.

[0035] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples. Example

[0036] Please refer to the following: Figure 2 A coal mine underground fire early warning device includes: a multi-parameter sensor body 1, a hook 2 and a suspension mechanism 3. The hook 2 is used to fix the device at a preset monitoring position underground. In order to better adapt to the suspension mechanism 3, the hook 2 preferably uses a rectangular cross-section.

[0037] Please refer to the following: Figure 1 The multi-parameter sensor body 1 is equipped with a parameter acquisition module, an integrated data processing and decision-making module, a data transmission module and a power supply module.

[0038] The parameter acquisition module is used to collect relevant parameter data required downhole and transmit the collected data to the integrated data processing and decision-making module. The parameter acquisition module includes a methane acquisition unit, a carbon dioxide acquisition unit, a carbon monoxide acquisition unit, and a temperature and humidity acquisition unit.

[0039] The integrated data processing and decision-making module is used to process data from various acquisition units, generate early warning information, control the working status of sensors, and is responsible for some data transmission; the integrated data processing and decision-making module includes a data monitoring and analysis unit, an early warning processing unit, a control logic unit, and some data transmission units;

[0040] The data monitoring and analysis unit is used to analyze data from each acquisition unit in real time and detect whether there are any abnormalities; the early warning processing unit is used to generate corresponding early warning information based on preset thresholds and algorithms, indicating possible safety risks or abnormalities; the control logic unit is used to implement corresponding control strategies based on the early warning information, and adjust the sensor acquisition frequency and working mode; and the partial data transmission unit is used to transmit partial data to external systems so that timely countermeasures can be taken.

[0041] This invention integrates traditional early warning, control, and partial transmission functions into a single module by setting up an integrated data processing and decision-making module. This reduces the number of hardware components and connection complexity, lowers system maintenance costs, and simplifies the system structure. Furthermore, it enables rapid response to data changes and generates real-time early warning information, enhancing the real-time monitoring capability of the system and improving the real-time monitoring capabilities of the sensors. Simultaneously, by optimizing data processing algorithms and control strategies, it reduces system energy consumption and extends sensor lifespan, achieving energy reduction. Compared to traditional multi-parameter sensor systems, this invention is more intelligent and efficient, enhancing its application value in fields such as safety monitoring and environmental monitoring. Example

[0042] Please refer to the following: Figure 2 and Figure 3 As a second embodiment of the present invention, the difference from the first embodiment is that: the suspension mechanism 3 is connected to the multi-parameter sensor body 1, and serves as a suspension connection structure for connection with the hook 2; the suspension mechanism 3 includes a suspension frame 31, an elastic body 32, a clamping component 33, and a cable winding component 34, and the bottom end of the suspension frame 31 is slidably connected to the outside of the multi-parameter sensor body 1; wherein, the suspension frame 31 includes a suspension section 311 and two connecting sections 312, the suspension section 311 is convex in shape, and the connecting sections 312 are inverted L-shaped, the suspension section 311 is located at the top of the multi-parameter sensor body 1, and its bottom end is connected to the ends of the two connecting sections 312 respectively; symmetrically distributed openings are provided on both sides of the multi-parameter sensor body 1. The slide groove 4, with two connecting sections 312 slidably installed in the two slide grooves 4 respectively; the elastic body 32 is fixedly installed between the top of the multi-parameter sensor body 1 and the upper end of the suspension frame 31. The elastic body 32 can be a spring, and the number of springs can be set to two, with the two springs symmetrically distributed on the left and right; the clamping component 33 is set at the suspension end where the suspension frame 31 is connected to the hook 2, and it is used to lock the suspension end of the suspension frame 31; when the suspension frame 31 is suspended at the bottom end of the hook 2, the clamping component 33 is in contact with the hook 2; the cable winding component 34 is set on one side of the multi-parameter sensor body 1, and it is used to wind the cable connected to the multi-parameter sensor body 1. The cable winding component 34 is connected to the suspension frame 31.

[0043] When the multi-parameter sensor body 1 needs to be calibrated or repaired, by pulling down the multi-parameter sensor body 1, the clamping component 33 is pulled and comes into contact with the side of the hook 2, keeping the suspension frame 31 and the hook 2 in a temporarily locked state. At the same time, the multi-parameter sensor body 1 moves down along the locked suspension frame 31, and the cable winding component 34 is synchronously driven by the suspension frame 31 to extend the cable, so that the cable adapts to the position change of the multi-parameter sensor body 1, so that the multi-parameter sensor body 1 is not restricted by the cable and can move down smoothly. The elastic body 32 is also extended. When the bottom end of the connecting section 312 moves to contact the upper end of the slide 4, the multi-parameter sensor body 1 moves down to the lowest position. At this time, the staff can directly perform calibration operation on the multi-parameter sensor body 1 without the aid of a ladder. After calibration, the staff only needs to slowly release the multi-parameter sensor body 1. Under the elastic force of the elastic body 32, the monitor can move up and reset itself, and the clamping component will automatically release the locked state. At the same time, the cable winding mechanism will also tighten the cable.

[0044] Thus, the suspension mechanism 3 provided in this invention serves as a connection structure between the multi-parameter sensor body 1 and the hook 2. It has a downward extension function. During calibration, the multi-parameter sensor body 1 can be pulled downwards, and at the same time, the downward movement of the multi-parameter sensor body 1 drives the cable winding component 34 to perform a cable unwinding action. Ultimately, the multi-parameter sensor body 1 can be smoothly lowered, allowing the operator to perform calibration operations independently on the ground without the need for a ladder or other personnel, greatly reducing the difficulty of calibration and simplifying the calibration operation steps. Furthermore, by providing a clamping component, the multi-parameter sensor body 1 can be automatically locked when subjected to tension, preventing the multi-parameter sensor body 1 from shifting position during the process, which is more conducive to the operator's operation.

[0045] Please refer to the following: Figures 4 to 6 In one embodiment of the present invention, the clamping component 33 is disposed at the top end of the suspension section 311. The clamping component 33 includes a contact drive component, a first locking component, and a second locking component. The contact drive component has an elastic telescopic function and is slidably disposed at the top end of the suspension section 311. When the multi-parameter sensor body 1 is pulled, the contact drive component retracts into the suspension frame 31. The first locking component and the second locking component are both connected to the contact drive component. When the contact drive component is subjected to a pulling force, it drives the first locking component and the second locking component to move and contact the outer side of the hook 2 in turn, thereby locking the suspension frame 31 in the X-axis and Y-axis directions, respectively.

[0046] The contact drive component includes a connecting rod 331, a contact base plate 332, a return spring 333, and a positioning knob 334. The connecting rod 331 is slidably mounted on the top end of the suspension section 311, with its two ends passing through both sides of the suspension section 311. The contact base plate 332 is fixedly connected to the bottom end of the connecting rod 331. The positioning knob 334 is threadedly connected to the top end of the connecting rod 331, and its bottom end is in contact with the top surface of the suspension section 311. The return spring 333 is fitted on the lower end of the connecting rod 331, with its two ends fixedly connected to the suspension section 311 and the contact base plate 332, respectively.

[0047] The first locking component includes two first pressing bodies 335 and two first movable rods 336. The two first pressing bodies 335 are symmetrically distributed in the suspension section 311 with the connecting rod 331 as the axis of symmetry and along the X-axis. The ends of the two first pressing bodies 335 are fixedly connected to the two sides of the connecting rod 331, respectively. The two first movable rods 336 are symmetrically slidably installed in the suspension section 311. The two first movable rods 336 are distributed one-to-one with the two first pressing bodies 335. One end of the first movable rod 336 is provided with a first inclined groove 337. The bottom end of the first pressing body 335 is slidably connected to the first inclined groove 337. One end of the first movable rod 336 is fixedly installed between it and the inner wall of the suspension section 311. The other end of the first movable rod 336 passes through one side of the suspension section 311 and is threaded with a first locking block 339.

[0048] The second locking component includes two second pressing bodies 3310 and two second movable rods 3311. The two second pressing bodies 3310 are symmetrically distributed in the suspension section 311 with the connecting rod 331 as the axis of symmetry and along the Y-axis. The ends of the two second pressing bodies are fixedly connected to the two sides of the connecting rod 331 respectively. The two second movable rods 3311 are symmetrically slidably installed in the suspension section 311, and the two second movable rods 3311 are distributed one-to-one with the two second pressing bodies 3310. One end of the second movable rod 3311 is provided with a second inclined groove 3312, and the bottom end of the second pressing body 3310 is slidably connected to the second inclined groove 3312. A second connecting spring 3313 is fixedly installed between one end of the second movable rod 3311 and the outside of the connecting rod 331. The other end of the second movable rod 3311 passes through one side of the suspension section 311 and is threaded with a second locking block 3314. The ends of the first locking block 339 and the second locking block 3314 are both provided with rubber pads 3315.

[0049] When the clamping component 33 is in use, the multi-parameter sensor body 1 is subjected to a downward pulling force and begins to move downward. At the same time, the contact base plate 332 is subjected to an upward force relative to the suspension frame 31, causing it to begin to retract into the suspension section 311, and driving the connecting rod 331 and the positioning knob 334 to move upward together. Meanwhile, the return spring 333 is compressed synchronously. The two first pressing bodies 335 and the two second pressing bodies 3310 move upward in the suspension section 311 along with the connecting rod 331, generating horizontal pressing forces on the two first movable rods 336 and the two second movable rods 3311 respectively. This causes the two first locking blocks 339 to move closer synchronously along the X-axis, and the corresponding first connecting spring 338 to be stretched. Meanwhile, the two second locking blocks 3314 move away synchronously along the Y-axis, and the corresponding second connecting spring 3313 to be stretched. When the return spring 333 is compressed to its maximum contraction state, the connecting rod 331 no longer continues to move upward. The movement allows the two second locking blocks 3314 to first engage with the inner ends of the hook 2, and then the two first locking blocks 339 to contact the outer ends of the hook 2. During the gradual contact between the second locking blocks 3314 and the inner ends of the hook 2, if the suspension section 311 is not in the middle position of the hook 2, the squeezing action of the two second locking blocks 3314 can adjust the suspension section 311 to the middle position. After the two first locking blocks 339 contact the outer sides of the hook 2, the entire suspension frame 31 and the multi-parameter sensor body 1 remain fixed to the hook 2, preventing further movement. Thus, before the multi-parameter sensor body 1 reaches its lowest position, the position of the multi-parameter sensor body 1 is automatically corrected and locked. This prevents movement of the multi-parameter sensor body 1 during subsequent calibration operations, making manual operation easier and reducing calibration difficulty.

[0050] Alternatively, if the locking function of the clamping component 33 is not required, the first locking block 339 and the second locking block 3314 are rotated to retract on the first movable rod 336 and the second movable rod 3311 respectively, until they can no longer rotate. At this time, the first locking block 339 and the second locking block 3314 are in a fully retracted state. Then, the positioning knob 334 is rotated, and the positioning knob 334 moves up and down on the connecting rod 331. The force generated by the positioning knob 334 can make the connecting rod 331 move up relative to the suspension frame 31, and drive the contact base plate 332 to move up. At the same time, the return spring 333 is compressed until the return spring 333 is compressed to the maximum retracted state. Since the first locking block 339 and the second locking block 3314 are both in the maximum retracted state, they cannot contact the hook 2. At this time, the clamping component 33 is in a fully retracted state and no longer plays a locking and clamping role. This is suitable for scenarios where the multi-parameter sensor body 1 needs to move during calibration or maintenance.

[0051] The clamping component 33 of this invention is mainly used to lock the position of the multi-parameter sensor body 1, enabling it to move stably downwards. It utilizes the force generated when the multi-parameter sensor body 1 moves downwards to lock the X-axis and Y-axis directions of the multi-parameter sensor body 1. This locking method not only provides a more secure locking effect, but also corrects the position of the suspension frame 31 by locking the Y-axis first and then the X-axis, ensuring that the suspension frame 31 is in the middle position of the hook 2. Thus, after calibration, no manual correction is required. Therefore, when not in use, the clamping component 33 is in a retracted state and does not affect the suspension connection between the suspension frame 31 and the hook 2. When in use, it not only has a better locking effect but also an automatic correction function, thus adapting well to the usage scenarios of the suspension frame 31.

[0052] Please refer to the following: Figure 2 , Figure 7 and Figure 8 As an embodiment of the present invention, the cable winding component 34 includes a protective housing 341, a winding wheel 342, a transmission gear 343, and a guide wheel 344. The protective housing 341 is detachably installed on one side of the multi-parameter sensor body 1. The winding wheel 342 is rotatably installed inside the protective housing 341, and a cable is wound around the outside of the winding wheel 342. The transmission gear 343 is fixedly mounted on the rotating shaft of the winding wheel 342. A toothed groove 345 is provided on one side of the connecting section 312 near the protective housing 341, and one side of the transmission gear 343 meshes with the toothed groove 345. The guide wheel 344 is located below the winding wheel 342, and one side of it is rotatably connected to the inner wall of the protective housing 341. One end of the cable passes through the guide wheel 344 and then passes through one side of the protective housing 341. An adjustment knob 346 is rotatably installed on one side of the protective housing 341, and one end of the adjustment knob 346 is fixedly connected to one side of the winding wheel 342.

[0053] When the cable winding component 34 is in use, the multi-parameter sensor body 1 is pulled downwards, and the entire cable winding component 34 moves downwards along with the multi-parameter sensor body 1. At this time, the transmission gear 343 begins to move downwards along the left side of the suspension frame 31 and rotates synchronously under the action of the tooth groove 345, thereby driving the winding wheel 342 to rotate counterclockwise. This allows the cable wound on its surface to gradually lengthen. The lengthened cable can adapt to the position change of the multi-parameter sensor body 1 without obstructing it, ensuring that the multi-parameter sensor body 1 can smoothly move downwards to the lowest position. After calibration, when the multi-parameter sensor body 1 moves upwards, the take-up wheel can be driven to rotate clockwise to tighten the cable. When it is necessary to adjust the suspension position of the multi-parameter sensor body 1, the adjustment knob 346 can be actively rotated to drive the take-up wheel to rotate, so that the length of the cable can adapt to the change.

[0054] This invention, by setting up the cable winding component 34, is mainly used for winding cables. By connecting the cable winding component 34 with the suspension frame 31, it can synchronously and adaptively wind the cable when the multi-parameter sensor body 1 is moving. This allows the cable to automatically adapt to the movement of the multi-parameter sensor body 1 without obstructing its movement, thus solving the problem of the cable hindering the movement of the multi-parameter sensor body 1. In addition, the cable winding component 34 can also wind the cable independently. When it is necessary to change the suspension position of the multi-parameter sensor body 1, the length of the cable can be adaptively adjusted by actively rotating the winding wheel, eliminating the need to cut or extend the cable, making it more flexible in use.

[0055] Please refer to the following: Figure 9 As a further optimization of the above solution, a fixing knob 313 is threadedly installed at the lower end of the connecting section 312 away from the cable winding component 34, and one end of the fixing knob 313 passes through one side of the connecting section 312.

[0056] After the multi-parameter sensor body 1 is pulled to its lowest position, the end of the sensor is moved to fit against the inner wall of the slide 4 by rotating the fixing knob 313. The friction generated by the contact between the fixing knob 313 and the inner wall of the slide 4 can lock the position of the suspension frame 31, preventing it from being pulled by the elastic body 32. At this time, the operator does not need to pull the multi-parameter sensor body 1 by hand, which further reduces the calibration difficulty and facilitates operation. Example

[0057] Please refer to the following: Figure 10 and Figure 11 As a third embodiment of the present invention, the difference from the second embodiment is that the suspension mechanism 3 further includes an adjustment component 35, which includes a fixed plate 351 and an adjustment rod 352. The two ends of the fixed plate 351 are fixedly connected to the bottom end of the suspension section 311, and the adjustment rod 352 is threadedly installed in the middle of the fixed plate 351, with its bottom end fitting against the top of the multi-parameter sensor body 1.

[0058] When in use, the aforementioned adjustment component 35 can generate a vertical force on the suspension frame 31 by rotating the adjustment rod 352, since its bottom end is in contact with the top of the multi-parameter sensor body 1. This force drives the suspension frame 31 to move up and down, thereby achieving the function of adjusting the height of the suspension frame 31. This meets the needs of different suspension heights of the multi-parameter sensor body 1 in actual use scenarios, further improving the installation flexibility of the multi-parameter sensor body 1.

[0059] The embodiments of this specific implementation have been described above, but this embodiment is not limited to the specific implementation described above. The specific implementation described above is merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this embodiment, all of which are within the protection scope of this embodiment.
