[0012] Preferably, the connecting valve pipe is composed of a hose and a regulating valve, and a detachable sleeve connection is arranged between the right end of the hose of the connecting valve pipe and the damping pipe of the valve pipe.

[0014] Preferably, step 1: prepare to wear the device, first wear the device, carry the back shell, the supporting part, the computing device, the adjusting part and the wire-releasing part behind the waist through the elastic waistband, and mount the extension identification module on the waist through the storage shell, and complete the preparation to wear the device through the above operations;

[0015] Step 2: Normal portable operation, before the extended identification module is released in normal conditions, the upper and lower air bags of the supporting part, the folding bags unfolded on both sides of the lower side, and the folding bag are all filled with helium. Since the density of helium is lower than that of air, it can provide buoyancy. Therefore, in normal conditions, the upper and lower air bags and the folding bags unfolded on both sides of the lower side can partially offset the gravity of the computing device, reducing the pressure on the back of the staff due to the weight of the equipment. At the same time, the helium filled in the folding bag can reduce the weight of the extended identification module stored in the storage shell, reducing the pressure on the waist of the staff, making the staff lighter during field investigations, and can cushion the computing device to prevent damage to the computing device caused by bumps in field movement;

[0016] Step 3: Ultra-long-distance voiceprint recognition operation. When ultra-long-distance voiceprint recognition is required, first open the connecting valve tube and the valve connecting tube to connect the lower airbag to the elastic bag through the connecting valve tube and the valve connecting tube. At this time, put your left hand behind your waist, pinch the pull ring and pull it to the left to turn the arm out of the storage slot. After turning 90 degrees, the block will contact the linkage arm, making the arm unable to rotate further. At this time, the staff can push the arm down to drive the linkage arm and the linkage bar to move downward. The downward movement of the linkage bar will drive the track block and the middle plate to move downward together, press down on the unfolded folding bag on the lower side, and make the hydrogen in the folding bag enter the lower airbag. The air is then transported into the elastic bag through the passage between the lower airbag and the elastic bag, causing the elastic bag to expand and expand. At this time, the connecting valve pipe and the valve connecting pipe are reset, closed and separated, and then the extended identification module is taken out from the storage shell. At this time, the extended identification module can float up due to the hydrogen filled in the elastic bag. Then the staff drives the reel to rotate by turning the knob to unwind the wound connecting rope, and as the connecting rope is continuously unwound, the moving range of the extended identification module continues to increase. At this time, the controller controls each electrical device to start, and connects the user terminal to the computing device through the data cable. The image captured by the camera can be transmitted to the computing device through the second signal transceiver and the first signal transceiver, and then transmitted to the user terminal for display. At this time, the staff can control the extension identification module to move through the terminal and the controller. First, the thrust of the running thrust fan can push the floating extension identification module to move. When turning is required, the push ring can be driven to move by controlling the extension and contraction of the electric push rod, so that the linkage and the rotating rod connected thereto can be rotated, and the rotation of the rotating rod can adjust the angle of the thrust fan to control the moving direction of the floating extension identification module. When it moves to the vicinity of wild animals, the thrust fan can be controlled to stop, so that the extension identification module floats near the wild animals. At this time, the sound emitted by the animal can be collected by the microphone, and the obtained audio data will be transmitted to the computing device through the second signal transceiver and the first signal transceiver, and the voiceprint analysis software running in the computing device can perform voiceprint analysis on the audio. The obtained voiceprint data can be sent to the user terminal for display on the one hand, and can be stored through the database management system running in the computing device on the other hand. The above operations complete the ultra-long-distance voiceprint recognition;

[0017] Step 4: Portable operation in the identification state. Although the downward movement of the middle connecting plate in the identification state will squeeze the lower folding bag and discharge the hydrogen, it will pull the upper folding bag to unfold. The unfolding of the upper folding bag will exhaust the upper airbag, and the upper airbag will exhaust the filled folding bag through the connecting tube to shrink the folding bag. At this time, since the extended identification module is no longer in the storage shell, the pressure on the right side of the staff's waist is suddenly reduced, so the contraction of the folding bag will not affect the portability, and the hydrogen in the folding bag will be replenished to the back shell, so that the supporting part can still reduce the pressure on the back of the staff's waist in the identification state, thereby reducing the weight of the staff. Through the above operations, the voiceprint recognition device can reduce the weight for the staff to carry.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the present invention, the extended recognition module, the adjustment part, the supporting part and other structures are set to enable ultra-long-distance voiceprint recognition. First, the connecting valve tube and the valve connecting tube need to be opened to connect the lower airbag with the elastic bag, and then the hydrogen is allowed to enter the airbag and the bag by operating the arm and the linkage component to expand the bag. Then, the extended recognition module is taken out from the storage shell and floated by hydrogen. The staff increases the moving range of the extended recognition module by unwinding the connecting rope, and then starts the device through the controller, and transmits the image to the computing device and the user terminal through the camera and each signal transceiver. The extended recognition module is operated by the controller, and its displacement and steering are controlled by the thrust fan and the electric push rod. After reaching the target position, the sound is collected by the microphone, and the audio data is transmitted to the computing device for voiceprint analysis, and the results are displayed on the user terminal and stored in the database, so as to complete the ultra-long-distance voiceprint recognition, and realize that the voiceprint recognition device can perform ultra-long-distance voiceprint recognition on wild animals through the extension and control mechanism, which solves the problem that the existing voiceprint recognition device is limited by the limited sound collection distance of the microphone and is difficult to recognize the voiceprint of wild animals at a long distance;

[0020] 2. In the present invention, the supporting part, computing device and main body are provided so that the airbag, folding bag and folding support bag of the supporting part are filled with helium. Since the density of helium is lower than that of air, it can provide buoyancy. Therefore, the gravity of the computing device can be partially offset by the airbag and folding bag, reducing the pressure on the back of the staff due to the weight of the equipment. At the same time, the helium filled in the folding support bag can reduce the weight of the extended identification module stored in the storage shell, reducing the pressure on the waist of the staff, making it lighter for the staff during field investigations, and cushioning the computing device to avoid damage to the computing device caused by bumps in the field, so that the voiceprint recognition device can be carried by the staff by reducing the weight, avoiding the influence of the weight of the equipment on the staff to carry and use in the field.

[0036] Workflow: The portable ultra-long-distance voiceprint recognition device is used in field investigations as follows: preparation for wearing, first wear it, carry the back shell 12, the supporting part 2, the computing device 3, the adjusting part 4 and the releasing part 6 behind the waist through the elastic waistband 11, and hang the extended recognition module 5 on the waist through the storage shell 15, and complete the preparation for wearing through the above operations; normal portable operation, before the extended recognition module 5 is released in the normal state, the upper and lower side airbags 21 of the supporting part 2, the folding bags 22 on both sides of the lower side and the folding support bag 25 are filled with helium, and because the density of helium is less than that of air, it can It can provide buoyancy, so in normal state, the upper and lower side airbags 21 and the folding bags 22 unfolded on both sides of the lower side can partially offset the gravity of the computing device 3, reducing the pressure on the back of the staff due to the weight of the equipment. At the same time, the helium filled in the folding bag 25 can reduce the weight of the extended identification module 5 stored in the storage shell 15, reducing the pressure on the waist of the staff, making the staff lighter during field investigations, and buffering the computing device 3 to avoid damage to the computing device 3 caused by bumps in the field; ultra-long-distance voiceprint recognition operation, when ultra-long-distance voiceprint recognition is required When the folding sack 21 is in the air, the connecting valve tube 26 and the valve connecting tube 53 are opened first, so that the lower air bag 21 is connected with the elastic bag 52 through the connecting valve tube 26 and the valve connecting tube 53. At this time, the left hand is put behind the waist, the pull ring 46 is pinched and pulled to the left, so that the arm rod 45 is rotated out of the storage groove 44. After rotating 90 degrees, the block 47 will contact the linkage arm 43, so that the arm rod 45 cannot be rotated further. At this time, the staff can push the arm rod 45 downward to drive the linkage arm 43 and the linkage bar 42 to move downward. The downward movement of the linkage bar 42 will drive the track block 41 and the middle connecting plate 23 to move downward together, and press down the folding bag 22 unfolded at the lower side, so that the folding bag 22 The hydrogen in the lower airbag 21 enters the lower airbag 21, and is transported into the elastic bag 52 through the passage between the lower airbag 21 and the elastic bag 52, so that the elastic bag 52 expands and expands. At this time, the connecting valve tube 26 and the valve connecting tube 53 are reset, closed and separated, and then the extended identification module 5 is taken out from the storage shell 15. At this time, the extended identification module 5 can float up due to the hydrogen filled in the elastic bag 52; then the staff drives the reel 64 to rotate by turning the knob 63, and unwinds the wound connecting rope 65, and as the connecting rope 65 is continuously unwound, the moving range of the extended identification module 5 continues to increase;At this time, the controller 7 controls each electrical device to start, and connects the user terminal to the computing device 3 through a data line. At this time, the image captured by the camera 55 can be transmitted to the computing device 3 through the second signal transceiver 59 and the first signal transceiver 18, and then transmitted to the user terminal for display. At this time, the staff can control the extension recognition module 5 to move through the terminal and the controller 7. First, the thrust of the running thrust fan 57 can push the floating extension recognition module 5 to move. When turning is required, the extension and retraction of the electric push rod 563 can be controlled. The push ring 564 is driven to move, thereby rotating the linkage 562 and the rotating rod 561 connected thereto, and the rotation of the rotating rod 561 can adjust the angle of the thrust fan 57, so as to control the moving direction of the floating extended identification module 5. When it moves near a wild animal, the thrust fan 57 can be controlled to stop, so that the extended identification module 5 floats near the wild animal. At this time, the sound of the animal can be collected through the microphone 54, and the obtained audio data will be transmitted to the computing device 3 through the second signal transceiver 59 and the first signal transceiver 18. The voiceprint analysis software running in the computing device 3 can perform voiceprint analysis on the audio. The obtained voiceprint data can be sent to the user terminal for display on the one hand, and can be stored through the database management system running in the computing device 3 on the other hand. The above operations complete the ultra-long-distance voiceprint recognition; portable operation in the recognition state, the downward movement of the middle connecting plate 23 in the recognition state will squeeze the lower folding bag 22 and discharge the hydrogen, but will pull the upper folding bag 22 to unfold, and the unfolding of the upper folding bag 22 will evacuate the upper airbag 21, and the upper The airbag 21 will evacuate the filled folding bag 25 through the connecting pipe 24, so that the folding bag 25 will shrink. At this time, since the extended identification module 5 is no longer in the storage shell 15, the pressure on the right side of the staff's waist is suddenly reduced. Therefore, the shrinkage of the folding bag 25 will not affect the portability, and the hydrogen in the folding bag 25 will be replenished to the back shell 12, so that the supporting part 2 can still reduce the pressure on the back of the staff's waist in the identification state, thereby reducing the weight of the staff. Through the above operation, the voiceprint recognition device can reduce the weight so that the staff can carry it. ;

9. A portable ultra-long-distance voiceprint recognition device and method using any one of claims 1-8, characterized in that: Step 1: Prepare to wear the device. First, wear the device. Use the elastic waistband (11) to carry the back shell (12), the supporting part (2), the computing device (3), the adjusting part (4) and the wire-releasing part (6) behind the waist. Use the storage shell (15) to mount the extended identification module (5) on the waist. The above operations complete the preparation to wear the device. Step 2: In normal portable operation, before the extended identification module (5) is released, the upper and lower air bags (21) of the supporting part (2), the folding bags (22) unfolded on both sides of the lower side, and the folding support bag (25) are all filled with helium. Since the density of helium is less than that of air, it can provide buoyancy. Therefore, in normal operation, the upper and lower air bags (21) and the folding bags (22) unfolded on both sides of the lower side can partially offset the gravity of the computing device (3), thereby reducing the pressure on the back of the staff due to the weight of the equipment. At the same time, the helium filled in the folding support bag (25) can reduce the weight of the extended identification module (5) stored in the storage shell (15), thereby reducing the pressure on the waist of the staff, making the staff more portable during field investigations, and can also cushion the computing device (3) to prevent the bumps of field movement from causing damage to the computing device (3); Step 3: Ultra-long-distance voiceprint recognition operation. When ultra-long-distance voiceprint recognition is required, first open the connecting valve tube (26) and the valve connecting tube (53) to connect the lower airbag (21) to the elastic bag (52) through the connecting valve tube (26) and the valve connecting tube (53). At this time, put your left hand behind your waist, pinch the pull ring (46) and pull it to the left to make the arm (45) turn out from the storage groove (44). After turning 90 degrees, the block (47) will contact the linkage arm (43), so that the arm (45) cannot be rotated further. At this time, the staff can push the arm (45) downward to drive the linkage arm (43) and the linkage bar (42) to move downward. The downward movement of the linkage bar (42) will drive the track block (41) and the middle connecting plate (23) to move downward together, so as to open the folding The bag (22) is pressed downward, so that the hydrogen in the folding bag (22) enters the lower air bag (21) and is transported into the elastic bag (52) through the passage between the lower air bag (21) and the elastic bag (52), so that the elastic bag (52) expands and unfolds. At this time, the connecting valve pipe (26) and the valve connecting pipe (53) are reset, closed and separated, and then the extension identification module (5) is taken out from the storage shell (15). At this time, the extension identification module (5) can float up due to the hydrogen filled in the elastic bag (52); then the staff drives the reel (64) to rotate by turning the knob (63), and unwinds the wound connecting rope (65). As the connecting rope (65) is continuously unwound, the moving range of the extension identification module (5) continues to increase;At this time, the controller (7) controls each electrical device to start, and connects the user terminal to the computing device (3) through a data line. At this time, the image captured by the camera (55) can be transmitted to the computing device (3) through the second signal transceiver (59) and the first signal transceiver (18), and then transmitted to the user terminal for display. At this time, the staff can control the extension identification module (5) to move through the terminal and the controller (7). First, the thrust of the running thrust fan (57) can push the floating extension identification module (5) to move. When turning is required, the extension and contraction of the electric push rod (563) can drive the push ring (564) to move, thereby causing the linked link (562) and the rotating rod (561) to rotate, and the rotation of the rotating rod (561) can The angle of the thrust fan (57) can be adjusted to control the moving direction of the floating extended identification module (5). When the extended identification module (5) moves near a wild animal, the thrust fan (57) can be controlled to stop operating so that the extended identification module (5) floats near the wild animal. At this time, the sound of the animal can be collected by the microphone (54). The obtained audio data will be transmitted to the computing device (3) through the second signal transceiver (59) and the first signal transceiver (18). The voiceprint analysis software running in the computing device (3) can perform voiceprint analysis on the audio. The obtained voiceprint data can be sent to the user terminal for display and stored in the database management system running in the computing device (3). The above operations complete the ultra-long-distance voiceprint recognition. Step 4: Portable operation in the identification state. Although the downward movement of the middle connecting plate (23) in the identification state will squeeze the lower folding bag (22) and discharge the hydrogen, it will pull the upper folding bag (22) to expand. The expansion of the upper folding bag (22) will evacuate the upper air bag (21), and the upper air bag (21) will evacuate the filled folding bag (25) through the connecting pipe (24), causing the folding bag (25) to shrink. At this time, since the extended identification module (5) is no longer in the storage shell (15), the pressure on the right side of the staff's waist is suddenly reduced, so the shrinkage of the folding bag (25) will not affect the portability, and the hydrogen in the folding bag (25) will be replenished to the back shell (12), so that the supporting part (2) can still reduce the pressure on the back of the staff's waist in the identification state, thereby reducing the weight of the staff. Through the above operation, the voiceprint recognition device can be carried by the staff by reducing the weight.
