Description

Technical Field

[0001] The present invention relates to an automatic intelligent communication signal enhancement device, specifically a device that can be used to detect the positions of workers in underground mines or tunnels in real time based on the use of MESH network technology. Background Art

[0002] The locations in tunnels or underground mines are remote, have long lengths, and complex environments. When workers are exploring or working in tunnels, their safety is difficult to guarantee. Especially in case of an accident, it is very difficult to determine the specific position information and vital signs of the workers, and it is impossible for rescue personnel to accurately rescue them in the first time. At present, the traditional tunnel accident rescue methods rely on the trapped personnel's loud calls for help and carpet-like searches. This method takes a long time, incurs high costs, and cannot ensure the safety of the search and rescue personnel themselves. Summary of the Invention

[0003] Aiming at the above-mentioned drawbacks existing in the prior art, the present invention provides an automatic blind compensation device and a life detection device based on MESH network applied to tunnels, which can communicate with tunnel workers in real time and obtain positions and vital signs in real time, and has very important practical significance.

[0004] The technical solution of the present invention is: a device capable of automatically ejecting a MESH relay module, including an L-shaped housing. Inside the vertical part of the L-shaped housing, a plurality of MESH relay modules are stacked longitudinally. An outlet for the lowermost MESH relay module to exit is provided on the left side wall of the vertical part of the L-shaped housing corresponding to the lowermost MESH relay module. A baffle is provided at the outlet, and a return spring for resetting the baffle is also connected between the baffle and the outlet. The right side of the lower end of the vertical part of the L-shaped housing is connected to the horizontal part of the L-shaped housing. The vertical part and the horizontal part of the L-shaped housing are communicated. A pushing mechanism is provided inside the horizontal part of the L-shaped housing. The pushing mechanism is used to push the lowermost MESH relay module in the vertical part of the L-shaped housing out of the outlet so that it is released.

[0005] The above-mentioned MESH relay module is an ESP32 module.

[0006] The upper end of the above-mentioned baffle is hinged to the upper edge of the outlet through a hinge shaft, and the return spring is a return torsion spring provided on the hinge shaft.

[0007] The above-mentioned pushing mechanism includes a stepper motor. The stepper motor is fixed at the right end inside the horizontal part of the L-shaped housing. The output shaft of the stepper motor is coaxially connected to one end of the threaded rod. The other end of the threaded rod is threadedly connected to the threaded channel opened on the push plate. The stepper motor is also signal-connected to the central control module. By controlling the forward and reverse rotation of the stepper motor through the central control module, it is used to push out the MESH relay module at the bottom layer through the push plate from the outlet and to reset the push plate.

[0008] The above-mentioned push plate includes a plate body for pushing the MESH relay module. A seat body is provided on the side of the plate body facing the stepper motor, and the threaded channel is opened inside the seat body.

[0009] A strap for tying to the human body is provided on the side wall of the vertical part of the above-mentioned L-shaped housing.

[0010] A life detection device based on the MESH network for use in tunnels includes: a safety helmet with MESH nodes and the device capable of automatically ejecting the MESH relay module. The device capable of automatically ejecting the MESH relay module is snap-connected to the left side of the safety helmet through a first snap; a second snap is provided at the front end of the safety helmet, and an LED light and a camera are attached through the second snap; a MESH communication module is provided on the left side of the safety helmet; a lithium battery pack is also provided on the safety helmet, and the lithium battery pack is used to supply power to the device for automatically ejecting the MESH relay module, the camera, the central control module, and the LED light. The power supply wires are arranged in the wire groove provided above the safety helmet; the lithium battery pack is fixed to the worker's waist through a waistband and a snap, and supplies power to the entire device through the wire groove on the upper side of the safety helmet.

[0011] A working method of a life detection device based on the MESH network for use in tunnels includes the following steps:

[0012] Collect on-site video information through the camera on the safety helmet;

[0013] Transmit the video information to the MESH communication module on the left side of the helmet. The MESH communication module transmits the video information and its own MESH node position information to the ground remote monitoring staff through the MESH network;

[0014] Automatically perform blind compensation of information signals for the underground or tunnel workers during the forward exploration process to ensure the stability of the transmission line.

[0015] The working process of the above-mentioned automatic blind compensation work includes the following steps:

[0016] When the node signal strength of the MESH relay module released most recently received by the MESH communication module is lower than -60 dB, a signal is sent to the central control module. The central control module controls the stepping motor to rotate, so that the push plate moves forward a certain distance, causing the MESH relay module to push open the baffle and be released. The released MESH relay module enters the working state. The released MESH relay module serves as a MESH network relay node to enhance the information transmission of the MESH communication module, thereby ensuring the stability of the transmitted signal; after the MESH relay module is released, the baffle closes again under the reset action of the spring; the stepping motor is controlled to rotate in the opposite direction, so that the push plate moves back to the original position by the same distance.

[0017] The beneficial effects of the present invention: The present invention provides an automatic intelligent communication signal enhancement device based on the use of MESH network technology. The device carries MESH network relay equipment, which can repair and fill in the blind area of the MESH network in tunnels or underground mines, and is used to detect the position and life information of workers in underground mines or tunnels in real time.

[0025] The following combines Figures 1-7 , and describes in detail a specific embodiment of the present invention, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

[0026] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the technical solution of the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. Those skilled in the art of the present technology can understand that unless otherwise defined, all terms (including technical terms and scientific terms) used here have the same meaning as the general understanding of those of ordinary skill in the art to which the present invention belongs. It should also be understood that terms such as those defined in a general dictionary should be understood to have a meaning consistent with the meaning in the context of the prior art, and will not be interpreted with an idealized or overly formal meaning unless defined as here.

[0027] Referring Figures 1-7 , a device capable of automatically ejecting a MESH relay module provided by the present invention includes an L-shaped housing. A plurality of MESH relay modules 8 are stacked longitudinally inside the vertical part of the L-shaped housing. An outlet for the lowermost MESH relay module 8 to exit is provided on the left side wall of the vertical part of the L-shaped housing corresponding to the lowermost MESH relay module 8. A baffle 10 is provided at the outlet, and a return spring 9 for resetting the baffle 10 is also connected between the baffle 10 and the outlet. The right side of the lower end of the vertical part of the L-shaped housing is connected to the horizontal part of the L-shaped housing, and the vertical part and the horizontal part of the L-shaped housing are communicated. A pushing mechanism is provided inside the horizontal part of the L-shaped housing. The pushing mechanism is used to push the lowermost MESH relay module 8 in the vertical part of the L-shaped housing out of the outlet so that it is released. When the lowermost MESH relay module 8 is pushed out of the L-shaped housing, the baffle 10 will cover the outlet under the action of the return spring 9, thereby preventing the next MESH relay module 8 that has not been pushed by the pushing mechanism and falls from the vertical part of the L-shaped housing from falling out of the outlet.

[0028] Furthermore, the MESH relay module 8 is a MESH network relay module device. The internal electrical system structure and principle of the MESH network relay module device are prior art. The MESH network relay module device is specifically an ESP32 module.

[0029] Further, the upper end of the baffle 10 is hinged to the upper edge of the outlet through a hinge shaft, and the return spring 9 is a return torsion spring provided on the hinge shaft. When the baffle 10 is reset, it will be quickly reset under the dual action of the return spring and its own gravity, preventing other MESH transfer modules 8 that do not need to be released from falling out of the outlet.

[0030] Further, as shown in Figure 7 , the pushing mechanism includes a stepping motor 11. The stepping motor 11 is fixed to the right end inside the horizontal part of the L-shaped housing. The output shaft of the stepping motor 11 is coaxially connected to one end of a threaded rod 20. The other end of the threaded rod 20 is threadedly connected to a threaded channel opened on a push plate 12. The threaded channel is arranged along the longitudinal direction of the horizontal part of the L-shaped housing. The push plate 12 is slidably connected longitudinally along the horizontal part of the L-shaped housing. The stepping motor 11 is also signal-connected to a central control module 14. By controlling the forward and reverse rotation of the stepping motor 11 through the central control module 14, it is used to push the bottom MESH transfer module 8 out of the outlet through the push plate 12 and realize the reset of the push plate 12. That is, when the stepping motor rotates forward and backward, under the guiding action of the threaded channel and the threaded rod, the push plate can move forward and backward. Specifically, the push plate 12 includes a plate body 12-1 for pushing the MESH transfer module 8. A seat body 12-2 is provided on the surface of the plate body 12-1 facing the stepping motor 11, and the threaded channel is opened in the seat body 12-2. A strap 13 for tying to the human body is provided on the side wall of the vertical part of the L-shaped housing and can be tied to the leg because a MESH network transfer module is very small and light.

[0031] An application of the MESH network-based life detection device for tunnels including the device capable of automatically ejecting MESH transfer modules of the present invention, comprising: a safety helmet 7 with MESH nodes and the device 15 capable of automatically ejecting MESH transfer modules. The device 15 capable of automatically ejecting MESH transfer modules is snap-connected to the left side of the safety helmet 7 through a first snap; a second snap is provided at the front end of the safety helmet 7, and an LED light and a camera 1 are connected through the second snap; a MESH communication module 2 is provided on the left side of the safety helmet 7; a lithium battery pack 4 is further provided on the safety helmet 7. The lithium battery pack 4 is used to supply power to the device 15 capable of automatically ejecting MESH transfer modules, the camera 1, the central control module 14, and the LED light. The power supply wires are arranged in a wire groove 3 provided above the safety helmet 7; the lithium battery pack 4 is fixed to the waist of the worker through a waistband 5 and a snap 6, and supplies power to the entire device through the wire groove 3 on the safety helmet 7.

[0032] A working method of the MESH network-based life detection device for tunnels of the present invention includes the following steps:

[0033] Collect the on-site video information through the camera on the safety helmet;

[0034] Transmit the video information to the MESH communication module 2 on the left side of the helmet. The MESH communication module 2 transmits the video information and its own MESH node position information to the ground remote monitoring staff through the MESH network;

[0035] Automatically perform blind compensation of information signals for the staff in the underground or tunnel during the forward exploration process to ensure the stability of the transmission line.

[0036] The working process of the above automatic blind compensation work includes the following steps:

[0037] When the node signal strength of the MESH relay module 8 (the MESH relay module is a node) released most recently received by the MESH communication module 2 is lower than -60 dB, send a signal to the central control module 14. The central control module 14 controls the stepping motor 11 to rotate, so that the push plate 12 moves forward a certain distance, and the MESH relay module 8 is pushed to open the baffle and released. The released MESH relay module 8 starts to work (when the MESH relay module 8 is inside the L-shaped housing, the elastic working switch button provided on its side wall will be compressed under the limiting action of the inner wall of the L-shaped housing, so that it is in the closed state. When it is released from the outlet, the elastic working switch will automatically pop up, so that the MESH relay module 8 is powered on and then in the working state). The released MESH relay module 8 serves as a MESH network relay node to enhance the information transmission of the MESH communication module 2 (that is, the information of the MESH communication module can be transmitted back to the remote through one node after another), so as to ensure the stability of the transmission signal; after the MESH relay module 8 is released, the baffle 10 is reset and closed again under the action of the spring 9; control the stepping motor 11 to rotate in the opposite direction, so that the push plate 12 moves back to the original position by the same distance.

[0038] In summary, the present invention provides an automatic intelligent communication signal enhancement device based on the use of MESH network technology. The device carried contains MESH network relay equipment, which can repair and supplement the blind area of the MESH network in the tunnel or underground, and is used to detect the position and life information of workers in the underground or tunnel in real time.

[0039] The above only discloses several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any changes that can be thought of by those skilled in the art should fall within the protection scope of the present invention.
