Through the above-mentioned settings, by setting the sensor body 1 to a regular shape and adopting a method of setting a plurality of side wings 2 at equal intervals on the outside, the sensor of the present invention can be conveniently placed in the vertical direction. In particular, the side wings 2 provided can more stably ensure the orientation of the sensor during the descent process, thereby facilitating the present invention to be accurately and stably placed at the target location. Furthermore, by providing a tail nail 4 at the bottom and making the center of gravity of the sensor coaxial and adjacent to the tail needle 4, the vertical orientation of the sensor during the landing process can be more effectively ensured, thereby enabling the present invention to be more accurately placed at the target location. In addition, the tail needle 4 provided can also be directly inserted vertically into the ground under the action of gravity, thereby ensuring that the sensor of the present invention is fixed at the placement position.

As shown in Figures 1, 2, 3, 4 and 5, according to an embodiment of the present invention, the sensor body 1 includes: a cylindrical shell 11, an upper cover assembly 12 detachably connected to the upper end of the cylindrical shell 11, a circuit structure 13 and a power supply structure 14 arranged in the cylindrical shell 11, and a counterweight cover assembly 15 detachably connected to the lower end of the cylindrical shell 11; in this embodiment, the circuit structure 13 is detachably connected to the lower side of the upper cover assembly 12; and the power supply structure 14 is detachably connected in the cylindrical shell 11. In this embodiment, the power supply structure 14 is electrically connected to the circuit structure 13. In this embodiment, the circuit structure 13 can be implemented using an FPGA board.

In this embodiment, the cylindrical shell 11 is provided with openings at the upper and lower ends in the axial direction, wherein the upper cover assembly 12 is mutually engaged with the opening at the upper end of the cylindrical shell 11, and a threaded connector is used at the edge of the upper cover assembly 12 to achieve fixation with the cylindrical shell 11. In this embodiment, an annular support is provided at the inner edge of the opening at the upper end of the cylindrical shell 11, and the upper cover assembly 12 is supported by the annular support, and the threaded connectors are mutually connected.

In this embodiment, the upper end of the cylindrical shell 11 is bent radially inward to form an opening for connecting the upper cover assembly 12, and the outer side of the upper end of the cylindrical shell 11 is made smoother so that the shape of the cylindrical shell 11 can better adapt to the smooth flow of external air.

As shown in FIG. 1 , FIG. 2 , FIG. 3 , FIG. 4 and FIG. 5 , according to an embodiment of the present invention, the upper cover assembly 12 includes: an upper cover body 121, an antenna connector 122, a charging interface 123, a hanging ear 124, and an antenna 125 connected to the antenna connector 122. In this embodiment, the antenna connector 122 is disposed at the center of the upper cover body 121, wherein the antenna connector 122 and the charging interface 123 are respectively connected to the circuit structure 13. In this embodiment, the hanging ears 124 are symmetrically disposed on opposite sides of the antenna connector 122.

In this embodiment, the upper cover body 121 is a circular plate body, and various holes are arranged on it to achieve fixed connection with the antenna connector 122 and the charging interface 123; wherein the antenna connector 122 and the charging interface 123 are arranged adjacently and spaced apart, so that the antenna connector 122 and the charging interface 123 are respectively fixed to the upper cover body 121 through their own locking nuts. Further, by arranging the antenna connector 122 at the center position of the upper cover body 121, when the antenna 125 is connected to the antenna connector 122, the antenna 125 is coaxial with the upper cover body 121, and the center of gravity of the antenna 125 and the antenna connector 122 is coaxial with the cylindrical shell 11, and in the process of placing the sensor of the present invention, it is more beneficial to ensure that the entire sensor is vertical during the falling process. In addition, by arranging the antenna 125 at the center position, the influence of the antenna 125 on the descending direction of the sensor can be effectively avoided, which is beneficial to ensure the stable falling of the present invention. In addition, by arranging the charging interface 123 adjacent to the antenna connector 122 , the mass of the charging interface 123 can be more easily and effectively concentrated at the center, which is beneficial to ensuring the vertical fall of the present invention.

In this embodiment, the symmetrical arrangement of the hanging ears 124 on the two opposite sides of the antenna connector 122 can make the mass distribution on the upper cover body 121 more uniform. In addition, through the symmetrical hanging ears 124, when the mounting part 3 is connected to the hanging ears 124, the mounting part 3 can surround the antenna 125, so that the sensor of the present invention is more vertically hoisted, so that the vertical fall is more beneficial. Therefore, when the mounting part 3 is connected to the external connection structure, the external connection structure is just above the antenna 125 to effectively avoid interference with the antenna 125.

In this embodiment, the mounting part 3 can be configured as a flexible hanging rope, for example, the mounting part 3 is a nylon rope, wherein the end of the mounting part 3 is connected to the hanging ear 124 by a knotted manner. By configuring the mounting part 3 as a hanging rope, the mounting part 3 of the present invention can be made lighter, and the present invention can effectively avoid the impact on the antenna 125 after landing.

In this embodiment, the upper cover body 121 can be made of an opaque PC material, and an indicator light display window can be provided thereon, and an indicator light lens 121a is embedded in the indicator light display window; wherein the indicator light lens 121a can be made of a PC lens and be black and semi-transparent. In this embodiment, the indicator light lens 121a and the indicator light display window on the upper cover body 121 are bonded and mutually engaged.

In this embodiment, a connecting leg is provided on the lower side of the upper cover body 121, and the circuit structure 13 can be supported and connected by the connecting leg; wherein the circuit structure 13 and the connecting leg are connected by a threaded connector. In this embodiment, the circuit structure 13 can adopt a PCB board structure, which realizes the corresponding micro-vibration detection function through the electrical connection between the power supply structure 14 and the antenna connector 122.

As shown in FIG. 1, FIG. 2, FIG. 3, FIG. 4 and FIG. 5, according to an embodiment of the present invention, the power structure 14 includes: a rechargeable battery 141 and a battery cover 142. In this embodiment, the battery cover 142 is used to accommodate the rechargeable battery 141 and to fix the rechargeable battery 141 in the cylindrical shell 11; wherein the cylindrical shell 11 is provided with a connecting plate 111 coaxially arranged with the cylindrical shell 11; the battery cover 142 is detachably connected to the connecting plate 111. In this embodiment, the connecting plate 111 is adjacent to the lower end of the cylindrical shell 11 and is arranged with a gap, so that the power structure 14 can be conveniently installed above the connecting plate 111; wherein the battery cover 142 is based on the method of arranging threaded connectors around to achieve fixation with the connecting plate 111, so that the rechargeable battery 141 can be conveniently confined between the connecting plate 111 and the battery cover 142. In this embodiment, the battery cover 142 can be made of PC opaque material, and the rechargeable battery 141 can be a lithium battery.

In this embodiment, the middle position of the connecting plate body 111 can be set to be hollow, so that the circuit structure 13 can be electrically connected to the detector 152 below through the hollow position, thereby realizing the collection of vibration signals.

As shown in FIG. 1, FIG. 2, FIG. 3, FIG. 4 and FIG. 5, according to one embodiment of the present invention, the counterweight cover assembly 15 includes: a counterweight cover 151, a detector 152 embedded in the counterweight cover 151, and a buffer pad 153 arranged at the end of the detector 152. In this embodiment, the counterweight cover 151 is detachably engaged with the lower end of the cylindrical shell 11, and the buffer pad 153 is arranged to abut against the connecting plate body 111. In this embodiment, the detector 152 is coaxially arranged with the counterweight cover 151, and the detector 152 is connected to the circuit structure 13.

In this embodiment, the counterweight cover 151 is made of stainless steel so that the counterweight cover 151 has a large mass, which can facilitate the sinking of the overall mass of the present invention to the bottom of the whole, thereby being more beneficial to ensuring the verticality of the present invention during the descent process, so as to effectively ensure accurate control of the overall posture.

In this embodiment, the upper end of the counterweight cover 151 is provided with an embedded installation groove, and the detector 152 can be embedded in the embedded installation groove. In order to ensure that the detector 152 and the embedded groove are installed reliably and stably, the shape and size of the embedded groove are matched with the shape of the detector 152, so that the sensor of the present invention can effectively avoid the shaking of the detector 152 during the launch process. Furthermore, the buffer pad 153 can be nested in the upper end of the detector 152, so that the upper side and upper end surface of the detector 152 can be protected, and then the annular protrusion provided on the middle part of the lower side of the connecting plate body 111 can limit the buffer pad 153 in the vertical direction, so as to effectively ensure the stable and reliable installation of the detector 152.

In this embodiment, the detector 152 is rigidly connected to the counterweight cover 151, and the micro-vibration signal within a range of 100 meters is collected through the contact between the counterweight cover 151 and the bottom surface. Specifically, after the detector collects the micro-vibration signal in the environment, it is transmitted to the circuit structure 13, and the circuit structure 13 amplifies the signal through the circuit, and then compares the amplified signal through a preset analysis algorithm, and finally identifies what kind of signal it is (such as a person walking, running, digging soil, various small animals walking, various cars, water flow, rain, etc.), and transmits the identification result to the background through a preset wireless network, and prompts or alerts are given in the background page or mobile terminal.

As shown in FIG. 1 , FIG. 2 , FIG. 3 , FIG. 4 and FIG. 5 , according to an embodiment of the present invention, the counterweight cover 151 includes: a fitting portion 151a and a cone portion 151b. In this embodiment, the fitting portion 151a and the cone portion 151b are coaxially arranged, and an embedding installation groove for embedding the detector 152 is arranged at the center position of the fitting portion 151a and the cone portion 151b. In this embodiment, the fitting portion 151a and the large end surface of the cone portion 151b are fixedly connected to each other, and the radial dimension of the fitting portion 151a is smaller than the radial dimension of the large diameter end of the cone portion 151b; in the direction away from the fitting portion 151a, the outer side surface of the cone portion 151b is a cone surface with a gradually decreasing radial dimension. In this embodiment, the tail nail 4 is detachably connected to the small diameter end of the cone portion 151b.

In this embodiment, the connecting plate body 111 and the engaging portion 151 a are connected by a threaded inner connector.

In this embodiment, the tail nail 4 is a stainless steel nail, which can be set as a conical nail as a whole, and the large diameter end of the tail nail 4 is connected to the small diameter end of the cone part 151b by a threaded connection. Through the above arrangement, the tail nail 4 is set as a stainless steel nail, which has high structural strength and large mass, and is beneficial to ensure that the present invention is stably inserted into the ground and increase the mass of the lower end of the present invention.

As shown in FIG. 1 , FIG. 2 , FIG. 3 , FIG. 4 and FIG. 5 , according to an embodiment of the present invention, the counterweight cover 151 further includes: a plurality of auxiliary side nails 151c; wherein the auxiliary side nails 151c are detachably connected to the cone portion 151b. In this embodiment, on the cone portion 151b, a plurality of auxiliary side nails 151c are arranged in a circumferential array around the tail nail 4; in the direction away from the counterweight cover 151, the tip of the tail nail 4 exceeds the tip of the auxiliary side nail 151c. In this embodiment, the auxiliary side nail 151c can also be set as a stainless steel nail, thereby, the auxiliary side nail 151c can effectively form an auxiliary support around the tail nail 4, so that when the sensor of the present invention is inserted into the ground and tilted, the tilted side will suppress the further tilt of the present invention due to the resistance of the auxiliary side nail 151c inserted into the ground, thereby guiding the sensor to be straightened and inserted in a relatively vertical posture, so as to achieve accurate and reliable deployment of the present invention. In addition, the auxiliary side nails 151c can effectively increase the contact range with the bottom surface, so that the surrounding micro-vibrations can be better sensed, which is beneficial to improving the sensitivity of the present invention.

In this embodiment, the auxiliary side nail 151c can be configured as a conical nail as a whole, and the large diameter end of the auxiliary side nail 151c is connected to the outer side surface of the cone portion 151b by a threaded connection. Through the above configuration, the auxiliary side nail 151c is configured as a stainless steel nail, which has high structural strength and large mass, and is beneficial for ensuring that the present invention is stably inserted into the ground and increasing the mass of the lower end of the present invention.

In this embodiment, the axial direction of the auxiliary side nail 151c is set parallel to the axial direction of the tail nail 4; or, the axial direction of the auxiliary side nail 151c is set to be inclined relative to the axial direction of the tail nail 4, wherein the auxiliary side nail 151c is set to extend outwardly from top to bottom, that is, it is set to be inclined in the direction away from the tail nail 4. Furthermore, since the inclined auxiliary side nail 151c can increase the supporting range of the auxiliary side nail 151c, the auxiliary side nail 151c can further effectively improve the effect of suppressing the skewness of the present invention, which is more beneficial to improving the accurate and reliable deployment of the present invention.

As shown in FIG6 , in another embodiment, the auxiliary side nail 151c can be connected to the cone part 151b in a sliding manner. Specifically, a mounting hole for connecting the auxiliary side nail 151c can be provided in the cone part 151b, and a controlled pop-up member A is provided in the mounting hole, wherein the end of the auxiliary side nail 151c is provided in contact with the controlled pop-up member A. In this embodiment, an opening structure 151c1 for opening the controlled pop-up member A is provided at the end of the auxiliary side nail 151c. In this embodiment, the opening structure 151c1 is opposite to the opening position on the controlled pop-up member A, and then the controlled pop-up member A can be deployed to achieve the auxiliary side nail 151c to extend a certain length, so that the auxiliary side nail 151c is inserted into the bottom surface to suppress the tilt of the present invention, and it can also be more convenient to reversely support the whole through the position where the auxiliary side nail 151c is connected to the cone part 151b, so that its tilt angle is further corrected, so that the posture of the present invention is more accurate.

Furthermore, the controlled pop-up member A can be configured as a compressed elastic member, which includes: a bottom support A1, a compression spring A2 disposed on the bottom support A1, and a binding member A3 for binding the compression spring A2 and the compression spring A2; wherein, in the binding state, the compression spring A2 is in a compressed state, and when the opening structure 151c1 cuts off the binding member A3, the compression spring A2 stretches to achieve elastic support on the auxiliary side nail 151c and the cone portion 151b. In this embodiment, the bottom support A1 includes: a hard plate body A11 and an elastic plate body A12, wherein the binding member A3 binds the compression spring A2 and the hard plate body A11 together to achieve compression limitation on the compression spring A2. Furthermore, the elastic plate body A12 is provided with a fitting opening, which is arranged opposite to the binding piece A3, and the edge of the fitting opening is installed against the opening structure 151c1, and then the auxiliary side nail 151c can be elastically positioned based on the elastic plate body A12, so that the opening structure 151c1 can be away from the binding piece A3. Only when the auxiliary side nail 151c is in contact with the ground and the contact resistance is greater than the elasticity of the elastic plate body A12, the elastic plate body A12 is deformed, and the opening structure 151c1 can move toward the direction close to the binding piece A3 until it is cut off, so that the elastic force of the compression spring A2 is released to produce a corresponding elastic support effect to suppress the tilt degree of the present invention. In this embodiment, the elastic plate body A12 can be set as an arc plate, a flat plate, etc., and the interval between the position where the fitting opening of the elastic plate body A12 is set and the hard plate body A11 is the largest, so that the interval position between the opening structure 151c1 and the binding piece A3 can be effectively controlled. Among them, the triggering conditions can be restricted by selecting the elastic plate A12 with different elastic forces, so that the present invention can be adjusted for different use environments. For example, in areas with soft ground, the elastic plate A12 with smaller elastic force can be selected to achieve triggering under low resistance, so as to avoid the disadvantage of difficulty in triggering at a large inclination angle in areas with soft ground. Correspondingly, in areas with hard ground, the elastic plate A12 with larger elastic force can be selected to avoid angle transition correction caused by small inclination angle triggering in areas with hard ground.

In this embodiment, in order to facilitate the cutting of the binding member A3, the opening structure 151c1 can be set as a protrusion with a blade edge at the upper end, so as to achieve accurate cutting of the binding member A3 through the positioning effect of the engaging opening on the elastic plate body A12. Correspondingly, in order to ensure the smooth cutting process, the binding member A3 can be set as a rope-like object that can compress and bind the compression spring A2 and can be broken by the opening structure 151c1 according to actual conditions.

In this embodiment, in order to maintain the stable and reliable engagement of the auxiliary side nail 151c with the engagement opening on the elastic plate body A12, a support spring 151b1 can be further provided at a position where the auxiliary side nail 151c and the elastic plate body A12 are spaced apart. The upper end of the support spring 151b1 can abut against the annular protrusion provided on the auxiliary side nail 151c, and the lower end can abut against the support structure 151b2 connected to the cone portion 151b. The auxiliary side nail 151c can be conveniently restricted in the corresponding mounting hole by the provided support structure 151b2 to ensure the reliable installation of the auxiliary side nail 151c. It should be noted that the function of the support spring 151b1 is to maintain the reliable positioning of the auxiliary side nail 151c with the engagement opening. For this purpose, the elastic force of the support spring 151b1 only needs to satisfy the supporting function of the auxiliary side nail 151c, and its elastic force should be smaller than the elastic force of the elastic plate body A12 to avoid the triggering of the controlled pop-up member A.

In another embodiment, the controlled pop-up member A can also be set as a micro-container storing high-pressure gas, which can also be realized by the aforementioned opening method. Specifically, the bottom support A1 and the compression spring A2 in the aforementioned controlled pop-up member A can be replaced with a micro-container with an elastic plate body A12. Then, when the opening structure 151c1 on the auxiliary side nail 151c is connected with the fitting opening on the elastic plate body A12, it is directly opposite to the bottom of the micro-container, so that the internal compressed gas can be released by puncturing the bottom of the micro-container through the opening structure 151c1. The position where the auxiliary side nail 151c is connected to the cone part 151b can be reversely supported for the whole, so that its inclination angle can be further corrected. Among them, in order to facilitate the puncture of the micro-container, the opening structure 151c1 can be set as a cone column to achieve a tip puncture effect. Of course, a groove can also be set at the bottom of the micro-container to achieve thinning at some positions, making it easier to open the micro-container.

In another embodiment, the controlled pop-up member A can also be set as a telescopic screw structure, the screw is connected to the upper end of the auxiliary side nail 151c, and the telescopic length of the auxiliary side nail 151c is accurately controlled by a micro motor connected to the telescopic screw structure.
