Description

Technical Field

[0001] The present invention belongs to the technical field of security warning, and particularly relates to a perimeter three-dimensional security warning system. Background Art

[0002] Security prevention is defined as follows: making preparations and protections to cope with attacks or avoid being victimized, so that the protected object is in a safe state without danger, being unharmed, and without accidents. Obviously, safety is the goal, and prevention is the means. Achieving or realizing the goal of safety through the means of prevention is the basic connotation of security prevention.

[0003] Existing security systems: some mainly use cameras, with the advantage of being able to directly see the target and make judgments, but the disadvantage is that it requires people to observe in real time, which is easy to get tired and miss the target; some mainly use millimeter-wave radars, with the advantage of being able to detect the target in time, but the disadvantage is that the target cannot be viewed in time, and the erection of a three-dimensional security system requires the arrangement of more diagonal braces to ensure its erection stability. The erection of diagonal braces is time-consuming and laborious, and the handling and transfer of diagonal braces will occupy more space. Therefore, we designed a perimeter three-dimensional security warning system that can plan terrain information, calculate the target height information accordingly, and convert it into the pitching angle of the pan-tilt head, so that the camera can correctly aim at the target, and can intuitively display the warning area, non-warning area, and radar target, and has a foldable erection structure, which brings convenience to installation. Summary of the Invention

[0004] The purpose of the present invention is to provide a perimeter three-dimensional security warning system, which has the advantages of being able to plan terrain information, calculate the target height information accordingly, convert it into the pitching angle of the pan-tilt head, so that the camera can correctly aim at the target, and can intuitively display the warning area, non-warning area, and radar target, and has a foldable erection structure, which brings convenience to installation, so as to solve the above problems in the background art.

[0005] The technical solution of the present invention to solve the above technical problems is as follows: a perimeter three-dimensional security warning system, which is installed on a support vertical pole. The security system is composed of four radars, a pan-tilt head, a camera, a controller, a display screen, and an alarm. The support vertical pole stands on the ground through a foldable and stable bracket;

[0006] Through multiple radars, the surrounding area is monitored. If a moving target is found, on the one hand, it is displayed on the display screen, and at the same time, the pan-tilt head is adjusted to make the camera aim at the target;

[0007] The system can plan a non-warning area (where moving objects are not alarmed) and a warning area (where moving objects are alarmed in time); the relevant coordinates are called ground coordinates;

[0008] After the radar detects the target, it will lock the target information and report it to the controller; the relevant coordinates are called radar coordinates;

[0009] The controller receives the target information reported by the radar, converts the radar coordinates into ground coordinates, and then makes a judgment: if it is in the non-alert area, no alarm is given; if it is in the alert area, an alarm message is sent and the alarm light is lit.

[0010] When there are targets that have not been recorded, according to the established strategy, the controller selects one of them for recording (for a predetermined duration).

[0011] The alert area, working area, and radar targets are displayed on the screen, and the relevant coordinates are called display coordinates.

[0012] A radar target can be selected on the screen for continuous tracking.

[0013] Based on the angle of the pan-tilt head and the target distance, terrain information can be generated: a sector refers to a fan-shaped area with a certain angle, and a segment is a different distance area within the fan-shaped area.

Please note that in order to clearly show the structures of the components in the embodiments of the present invention, the drawings are not drawn according to the same scale. The same reference numerals are used to represent the same parts.

[0048] Embodiment 1: Figures 1-13 A perimeter three-dimensional security warning system showing an embodiment of the present invention is installed on a support vertical pole 2. The security system 1 is composed of four radars, a pan-tilt unit, a camera, a controller, a display screen, and an alarm. The support vertical pole 2 stands on the ground through a foldable and stable bracket;

[0049] Through multiple radars, the surrounding area is monitored. If a moving target is detected, on the one hand, it is displayed on the display screen, and at the same time, the pan-tilt unit is adjusted to make the camera aim at the target;

[0050] The system can plan a non-alarm area (no alarm for moving objects therein) and an alarm area (timely alarm for moving objects therein); the relevant coordinates are called ground coordinates;

[0051] After the radar detects a target, it will lock the target information and report it to the controller; the relevant coordinates are called radar coordinates;

[0052] Such as Figure 8 , the controller receives the target information reported by the radar, converts the radar coordinates into ground coordinates, and then makes a judgment: if it is in the non-alarm area, no alarm is given; if it is in the alarm area, an alarm message is sent and the alarm light is lit;

[0053] When there is a target that has not been recorded, according to the established strategy, the controller selects one of them for recording (for a predetermined duration);

[0054] The alarm area, working area, and radar targets are displayed on the screen, and the relevant coordinates are called display coordinates;

[0055] A radar target can be selected on the screen for continuous tracking;

[0056] Such as Figure 9 New terrain sector step system diagram, terrain information can be generated according to the angle of the pan-tilt unit and the target distance: a sector refers to a fan-shaped area with a certain angle, such as Figure 10 New terrain segmentation step system diagram, segmentation is different distance areas within the fan-shaped area, such as Figure 13 Schematic diagram of the fan-shaped area;

[0057] When performing tracking or recording, according to the terrain information, calculate the height information of the target and convert it into the pitch angle of the pan-tilt unit;

[0058] Calculate the pitch angle of the pan-tilt unit according to the target information and the terrain information

[0059] The calculation schematic diagram is as Figure 11 and Figure 12 ; Explanation:

[0060] Segmentation: Starting distance AD, starting angle DAJ; Ending distance AF, ending angle FAJ;

[0061] Target: Distance AG;

[0062] The angle GAJ is the pan-tilt angle to be calculated, and GI is the height of the target;

[0063] Calculation steps:

[0064] Calculation: Starting height DJ = AD * sin(angle DAJ), ending height BF = AF * sin(angle FAJ); Calculation: Angle DAF = angle DAJ - angle FAJ, segmented distance DF = sqrt(AD * AD + AF * AF - 2 * AD * AF * cos(DAF));

[0065] Calculation: Height EF = height DJ - height BF, angle GDI = arccos(EF / DF);

[0066] Calculation of angle ADG, given that angle ADC = angle DAJ, angle ADG = 180 - angle ADC - angle GDI;

[0067] Calculation: Angle AGD = arcsin(sin(angle ADG) / AG * AD);

[0068] Calculation: Angle DAG = 180 - angle AGD – angle ADG;

[0069] Calculation: Angle GAJ = angle DAJ - angle DAG;

[0070] The foldable stabilizing bracket includes a movable collar 3 installed on the surface of the support vertical rod 2 and a base sleeve 4 installed at the bottom end of the surface of the support vertical rod 2. Both the base sleeve 4 and the movable collar 3 are fixedly installed on the surface of the support vertical rod 2 through three fasteners 5. Three planar support steels 6 are rotatably connected to the surface of the base sleeve 4 in a circumferential array through rotating shafts. A first rectangular groove 7 is formed at the top of the planar support steel 6. A rotatable telescopic assembly 8 is arranged in the inner cavity of the first rectangular groove 7. The telescopic assembly 8 includes a tube body 81 rotatably connected to the inner cavity of the first rectangular groove 7 through a rotating shaft. A rod body 82 is slidably connected to the inner cavity of the tube body 81. One end of the rod body 82 away from the tube body 81 is fixedly connected with an anti-detachment abutting block 13. The bottom of the movable collar 3 is fixedly connected with an external threaded tube 9. A threaded sleeve 10 is threadedly connected to the surface of the external threaded tube 9. The bottom of the threaded sleeve 10 is rotatably connected to a movable tube 11. Three abutting rings 12 are fixedly connected to the surface of the movable tube 11 in a circumferential array. The inner wall of the anti-detachment abutting block 13 abuts against the abutting rings 12. A second rectangular groove 14 is formed on the outer side of the bottom of the planar support steel 6.

[0071] Embodiment 2: It is basically the same as Embodiment 1. Further, a rotating shaft frame 83 is fixedly connected to the end of the surface of the tube body 81. A limiting block 84 is slidably connected to the inner cavity of the rotating shaft frame 83. The end of the limiting block 84 penetrates into the inner cavity of the tube body 81 and is adapted to the rod body 82. An eccentric rotating block 85 is rotatably connected to the inner cavity of the rotating shaft frame 83 through a rotating shaft. The eccentric rotating block 85 abuts against the limiting block 84. A fixing plate 86 is fixedly connected to one side of the rotating shaft frame 83. Two symmetrical movable rods 87 are arranged through the fixing plate 86. The movable rods 87 are slidably connected to the fixing plate 86. One end of the movable rod 87 is fixedly connected to the limiting block 84. A first spring 88 is sleeved on the surface of the movable rod 87. Through the arrangement of the movable rod 87, the movement of the limiting block 84 will drive the movable rod 87 to slide on the fixing plate 86, providing guidance and limitation for the movement of the limiting block 84, effectively restricting the movement direction of the limiting block 84, and improving the stability of the movement of the limiting block 84. The two ends of the first spring 88 respectively abut against the limiting block 84 and the fixing plate 86. A limiting arc groove 89 adapted to the eccentric rotating block 85 is formed on one side of the limiting block 84. A guiding strip 810 is fixedly connected to the surface of the rod body 82. A guiding groove 811 for the guiding strip 810 to slide is formed in the inner cavity of the tube body 81. Through the cooperation of the guiding strip 810 and the guiding groove 811, when the rod body 82 is pulled out from the inner cavity of the tube body 81, the guiding strip 810 will slide in the inner cavity of the guiding groove 811, ensuring that the rod body 82 will not rotate in the inner cavity of the tube body 81, improving the stability of the movement of the rod body 82, and also enabling the anti-detachment abutting block 13 to be aligned with the abutting rings 12, effectively avoiding deviation.

[0072] Embodiment 3: It is basically the same as Embodiment 1. Further, the limiting component 16 includes a limiting rod 161 penetrating through one side of the planar support steel 6. One end of the limiting rod 161 penetrates into the inner cavity of the second rectangular groove 14 and abuts against the ends of the two tapered rods 15. The surface of the limiting rod 161 is slidably connected to the planar support steel 6. A pull ring 162 is fixedly connected to one end of the limiting rod 161. A second spring 163 is sleeved on the surface of the limiting rod 161. The two ends of the second spring 163 are respectively fixedly connected to the pull ring 162 and the planar support steel 6.

[0073] Embodiment 4: It is basically the same as Embodiment 1. Further, an annular cavity 19 for the movable tube 11 to rotate is formed at the bottom of the threaded sleeve 10. An annular groove 20 is formed in the inner cavity of the annular cavity 19. A rotating ring 21 that rotates in the inner cavity of the annular groove 20 is fixedly connected to the top of the surface of the movable tube 11. Limiting strips 22 are fixedly connected to both sides of the inner cavity of the movable tube 11. Limiting grooves 23 for the limiting strips 22 to slide are formed on both sides of the surface of the external threaded tube 9. Through the combined use of the annular cavity 19, the annular groove 20, the rotating ring 21, the limiting strips 22, and the limiting grooves 23, when the threaded sleeve 10 rotates, it will move downward and rotate due to the external threaded tube 9. The rotating ring 21 on the movable tube 11 will rotate in the inner cavity of the annular groove 20, preventing the movable tube 11 from rotating following the rotation of the threaded sleeve 10. Moreover, when the movable tube 11 moves downward, the limiting strips 22 will slide in the inner cavities of the limiting grooves 23 on the surface of the external threaded tube 9, guiding and limiting the movement of the movable tube 11, and improving the stability of the movement of the movable tube 11.

[0074] The working principle of the foldable and stable support is as follows: The security system 1 is fixedly installed at the top of the support vertical rod 2. Then, pull the planar support steel 6 so that the planar support steel 6 disengages from the inner cavity of the U-shaped sleeve 17. Pull the pull ring 162 so that the limiting rod 161 disengages from the limit on the tapered rod 15. The tapered rod 15 will rotate due to its own gravity. Right the tapered rod 15 so that the tapered rod 15 pierces into the ground. Then, rotate the telescopic assembly 8 out of the inner cavity of the rectangular groove 1 7. Pull the rod body 82 until the anti-disengagement abutting block 13 at the end of the rod body 82 is sleeved on the abutting ring 12. Then, operate the eccentric rotating block 85 to rotate upward. The eccentric rotating block 85 will abut against the limiting block 84 and move towards the rod body 82, so that the limiting block 84 firmly abuts on the surface of the rod body 82, restricting the movement of the rod body 82 in the inner cavity of the pipe body 81 and locking the lengths of the rod body 82 and the pipe body 81. Then, operate the threaded sleeve 10 to rotate on the surface of the external threaded pipe 9. The threaded sleeve 10 moves downward and rotates due to the thread and then drives the movable pipe 11 to move downward. The movable pipe 11 drives the abutting ring 12 to move downward, so that the abutting ring 12 firmly abuts in the inner cavity of the anti-disengagement abutting block 13, and the setup is completed. When folding, rotate the eccentric rotating block 85 downward. The eccentric rotating block 85 will cancel the force applied to the limiting block 84. The limiting block 84 will move outward due to the restoring force of the spring 1 88, so that the limiting block 84 disengages from the contact with the rod body 82. Then, the rod body 82 can be inserted into the inner cavity of the pipe body 81. The telescopic assembly 8 is stored in the inner cavity of the rectangular groove 1 7. The tapered rod 15 is pulled out of the ground. The tapered rod 15 is rotated into the inner cavity of the rectangular groove 2 14 and is limited by the limiting rod 161. Rotate the planar support steel 6 into the inner cavity of the U-shaped sleeve 17. The planar support steel 6 abuts against the limiting arc strip 18, which will cause the U-shaped sleeve 17 to deform until the planar support steel 6 enters the deep part of the inner cavity of the U-shaped sleeve 17. The restoring force of the U-shaped sleeve 17 causes the limiting arc strip 18 to restrict the planar support steel 6, and the planar support steel 6 will not move without external force.

[0075] In summary, for the perimeter three-dimensional security warning system, the foldable and stable support enables the security system 1 to be quickly and stably erected on the ground. Moreover, the security system 1 can conveniently plan the warning area and non-warning area, can visually display the warning area, non-warning area, and radar targets, can automatically record the targets that have not been recorded, can specify targets and continuously track them, can plan terrain information, calculate the target height information based on this, and convert it into the pan-tilt angle of the pan-tilt head, so that the camera can correctly aim at the target.
