Description

Technical Field

[0001] This invention relates to the field of security equipment technology, and in particular to a protective fence and its calibration method. Background Technology

[0002] Currently, electronic fences are widely used in scenarios requiring high security, refined management, or protection in special environments. As an advanced protection system that integrates electronic technology and security concepts, it delineates restricted areas through virtual or physical means, enabling core functions such as proactive defense, precise monitoring, and flexible adaptation. It can effectively deter, block, and alarm against intrusion, providing reliable security for various scenarios.

[0003] However, the components of existing electronic fences are generally fixed using bolts or welding, making disassembly difficult. This results in significant time and labor costs during relocation, assembly, and maintenance, severely limiting deployment flexibility and operational efficiency. Furthermore, in the position calibration stage, existing solutions largely rely on manual observation of the laser emitted by the electronic fence. This not only leads to low calibration efficiency but also makes it difficult to guarantee accuracy, failing to meet the practical application requirements of some high-precision protection scenarios.

[0004] Therefore, there is an urgent need for a protective fence and its calibration method to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a protective fence and its calibration method, in which the components can be quickly disassembled and connected, and the efficiency and accuracy of position calibration are significantly improved.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] On the one hand, a protective fence is provided, including a support module, a calibration module, a connection module and a control module, wherein the calibration module is configured to emit and receive calibration light;

[0008] The connection module includes a first connector and a second connector that can be detachably connected. The first connector is disposed on the support module, and the calibration module is rotatably connected to the second connector. One of the first connector and the second connector is provided with a movable locking member. The locking member has a locked state and an unlocked state. In the locked state, the locking member is engaged with the other of the first connector and the second connector, and the first connector and the second connector are connected. In the unlocked state, the locking member is disengaged from the other of the first connector and the second connector, and the first connector and the second connector are separated.

[0009] The control module is electrically or communicatively connected to the calibration module. The control module is configured to control the opening and closing of the calibration module, record the intensity value of the received calibration light, and control the rotation angle of the calibration module.

[0010] Optionally, the connection module also includes an elastic operating member movably disposed on the first connecting member or the second connecting member. The elastic operating member is provided with a pushing inclined surface arranged at an angle to the locking member. The locking member contacts and slides with the pushing inclined surface, driving the elastic operating member to move along the first direction. The pushing inclined surface pushes the locking member to move along the unlocking direction, and the locking member switches from the locked state to the unlocked state.

[0011] Optionally, the elastic operating member includes an operating part and an elastic part. A pushing inclined surface is provided on the operating part. One end of the elastic part is connected to a first connecting member or a second connecting member, and the other end is connected to the operating part. The operating part moves in a second direction under the elastic force of the elastic part. The second direction is opposite to the first direction.

[0012] Optionally, the first or second connector is provided with an elastic element that is connected to the locking element, and the locking element abuts against the pushing slope under the elastic force of the elastic element.

[0013] Optionally, the support module includes a support body, a support base, and a connecting component. The lower end of the support body is detachably connected to the support base via the connecting component, and the upper end of the support body is connected to the first connecting member.

[0014] Optionally, the support base is provided with multiple traveling components, which are arranged at intervals along the circumference of the support base.

[0015] Optionally, the calibration module includes a transmitter and a receiver, and the protective fence also includes a transmitter driver and a receiver driver. Both the transmitter driver and the receiver driver are located on the second connector. The output end of the transmitter driver is connected to the transmitter and is used to drive the transmitter to rotate around its own axis. The output end of the receiver driver is connected to the receiver and is used to drive the receiver to rotate around its own axis.

[0016] Optionally, the other of the first and second connectors is provided with a locking groove, and the locking member can engage or disengage from the locking groove.

[0017] Optionally, the control module includes a control switch, a control circuit board, and a transmission circuit board. The control switch, control circuit board, and transmission circuit board are all electrically connected to the calibration module. The control switch is located on the second connector and is configured to control the opening and closing of the calibration module. The transmission circuit board is electrically or communicatively connected to the control circuit board and is configured to transmit the intensity value of the received calibration light to the control circuit board. The control circuit board is configured to control the rotation of the calibration module and record the intensity value of the received calibration light.

[0018] On the other hand, a method for calibrating a protective fence is provided, which is used to calibrate the emission direction of the calibration light of the aforementioned protective fence, wherein multiple protective fences are arranged at intervals along the protection direction;

[0019] The method for calibrating a protective fence includes the following steps:

[0020] The calibration module is activated using the control module, and the protective fence adjacent to the protective fence to be calibrated receives the calibration light emitted by the protective fence to be calibrated.

[0021] The control module drives the corresponding calibration module to rotate, which changes the direction of the calibration light emitted by the protective fence to be calibrated, and changes the intensity of the calibration light received by the adjacent protective fence.

[0022] The calibration position of the calibration module of the fence to be calibrated is determined when the intensity of the calibration light recorded by the calibration module of the adjacent protective fence is the maximum.

[0023] Determine whether the calibration module of the protective fence to be calibrated and the calibration modules of the adjacent protective fences are both in the calibration position. If so, complete the calibration of the emission direction of the calibration light of the protective fence to be calibrated. If not, drive the calibration modules of the two adjacent protective fences that are not in the calibration position to rotate until the calibration modules of the two adjacent protective fences are rotated to the calibration position.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] This invention provides a protective fence and its calibration method. After the locking member engages with the other of the first and second connecting members, the first connecting member can be stably connected to the second connecting member, allowing the calibration module to be securely installed on the support module, improving the reliability and safety of the protective fence during use. By releasing the locking member from the other of the first and second connecting members, the first and second connecting members can be separated, and the calibration module also separates from the support module. This achieves rapid separation of the calibration module from the support module, and is convenient to operate, significantly improving the deployment flexibility and maintenance efficiency of the protective fence. In the locked state, during the rotation of the driving calibration module, the angle of the calibration light emitted to the adjacent protective fence changes, and the intensity of the calibration light received by the adjacent protective fence changes. When the intensity of the calibration light received by the calibration module is at its maximum, it indicates that the straight line connecting the two protective fences is collinear with the calibration light. At this point, the position of the calibration module is the calibration position, and the direction of the calibration light is the direction required for protection. During the calibration process, the maximum intensity of the calibration light and the rotation angle of the calibration module are both controlled by the control module. Compared with existing technologies, no manual control is required, which significantly improves the efficiency and accuracy of the protective fence position calibration. Attached Figure Description

[0043] Example 1

[0044] like Figures 1 to 5 As shown, this embodiment provides a protective fence, in which the components can be quickly disassembled and connected, and the efficiency and accuracy of position calibration are significantly improved.

[0045] See Figure 1 and Figure 2The protective fence includes a support module 100, a calibration module 200, a connection module 300, and a control module. The calibration module 200 is configured to emit and receive calibration light. The connection module 300 includes a detachably connected first connector 310 and a second connector 320. The first connector 310 is disposed on the support module 100, and the calibration module 200 is rotatably connected to the second connector 320. A movable locking member 330 is provided on one of the first connector 310 and the second connector 320. The locking member 330 has a locked state and an unlocked state. In the unlocked state, the locking member 330 engages with the other of the first connector 310 and the second connector 320, and the first connector 310 is connected to the second connector 320. In the unlocked state, the locking member 330 disengages from the other of the first connector 310 and the second connector 320, and the first connector 310 is separated from the second connector 320. The control module is electrically or communicatively connected to the calibration module 200. The control module is configured to control the opening and closing of the calibration module 200, record the intensity value of the received calibration light, and control the rotation angle of the calibration module 200.

[0046] In this embodiment, the protective fence, after the locking member 330 engages with the other of the first connecting member 310 and the second connecting member 320, allows the first connecting member 310 to be stably connected to the second connecting member 320, enabling the calibration module 200 to be securely installed on the support module 100, thus improving the reliability and safety of the protective fence during use. By releasing the locking member 330 from the other of the first connecting member 310 and the second connecting member 320, the first connecting member 310 and the second connecting member 320 can be separated, and the calibration module 200 will also separate from the support module 100. This achieves rapid separation of the calibration module 200 from the support module 100, and is convenient to operate, significantly improving the deployment flexibility and maintenance efficiency of the protective fence. In the locked state, during the rotation of the driving calibration module 200, the angle of the calibration light emitted to the adjacent protective fence changes, and the intensity of the calibration light received by the adjacent protective fence changes. When the calibration light received by the calibration module 200 reaches its maximum intensity, it indicates that the straight line connecting the two protective fences is collinear with the calibration light. At this point, the position of the calibration module 200 is the calibration position, and the direction of the calibration light is the required direction for protection. During the calibration process, the maximum intensity of the calibration light and the rotation angle of the calibration module 200 are controlled by the control module. Compared with existing technologies, manual control is no longer required, significantly improving the efficiency and accuracy of protective fence position calibration.

[0047] In this embodiment, the appropriate type of calibration module 200 can be selected according to the specific protection situation, and the calibration module 200 can be connected to the support module 100 through the connection module 300 to meet the diverse and flexible security deployment needs.

[0048] Optionally, see Figure 1 and Figure 2 The connecting module 300 also includes an elastic operating member 340 movably disposed on the first connecting member 310 or the second connecting member 320. The elastic operating member 340 is provided with a pushing inclined surface 3411 arranged at an angle to the locking member 330. The locking member 330 contacts and slides with the pushing inclined surface 3411, driving the elastic operating member 340 to move along the first direction. The pushing inclined surface 3411 pushes the locking member 330 along the unlocking direction. Figure 2 The locking component 330 moves in the X direction and switches from the locked state to the unlocked state, which facilitates quick operation by staff and improves the convenience and efficiency of separating the calibration module 200 from the support module 100.

[0049] Among them, see Figure 2 One end of the locking member 330 contacts the pushing ramp 3411, and the other end is detachably connected to the first connecting member 310 or the second connecting member 320. The pushing ramp 3411 gradually approaches the other end of the locking member 330 along a first direction. The unlocking direction gradually moves from the end of the locking member 330 away from the pushing ramp 3411 along the extension direction of the locking member 330 towards the end of the locking member 330 that contacts the pushing ramp 3411.

[0050] For example, the first direction is preferably perpendicular to the unlocking direction.

[0051] In this embodiment, see Figure 2 The locking member 330 and the elastic operating member 340 are both movably disposed on the second connecting member 320, or the locking member 330 and the elastic operating member 340 are both movably disposed on the first connecting member 310.

[0052] For example, one of the first connector 310 and the second connector 320 includes an outer connecting ring, and the other of the first connector 310 and the second connector 320 includes an inner connecting ring, with the outer connecting ring sleeved outside the inner connecting ring. Both the locking member 330 and the elastic operating member 340 are at least partially movable within the inner cavity of the inner connecting ring. In the locked state, the locking member 330 passes through the inner connecting ring and engages with the outer connecting ring; in the unlocked state, the locking member 330 is released from engagement with the outer connecting ring.

[0053] In other embodiments, the locking member 330 is disposed on one of the first connector 310 and the second connector 320, and the elastic operating member 340 is disposed on the other of the first connector 310 and the second connector 320.

[0054] For example, one of the first connector 310 and the second connector 320 includes an outer connecting ring, and the other of the first connector 310 and the second connector 320 includes an inner connecting ring, with the outer connecting ring sleeved outside the inner connecting ring. A locking member 330 is movably disposed on the inner connecting ring, and an elastic operating member 340 is movably disposed on the outer connecting ring. In the locked state, the locking member 330 engages with the outer connecting ring, driving the elastic operating member 340 to move. The pushing inclined surface 3411 drives the locking member 330 to move in a direction away from the outer connecting ring, and the locking member 330 switches from the locked state to the unlocked state.

[0055] In this embodiment, see Figure 1 and Figure 2 The elastic operating member 340 includes an operating part 341 and an elastic part 342. A pushing inclined surface 3411 is disposed on the operating part 341. One end of the elastic part 342 is connected to the first connecting member 310 or the second connecting member 320, and the other end is connected to the operating part 341. Under the elastic force of the elastic part 342, the operating part 341 moves in a second direction, which is opposite to the first direction. When the operating part 341 moves in the second direction, the pushing inclined surface 3411 pushes against the locking member 330 in the opposite direction to the unlocking direction, so that the locking member 330 can automatically switch to the locked state. This configuration ensures that the locking member 330 can only switch to the unlocked state under external force. When there is no external force, the locking member 330 can automatically switch and remain in the locked state, guaranteeing the reliability of the connection between the calibration module 200 and the support module 100. Moreover, when switching the locking member 330 from the locked state to the unlocked state, the driving force must overcome the elastic force of the elastic part 342 to drive the operating part 341 to move, effectively avoiding the separation of the first connecting member 310 and the second connecting member 320 due to accidental contact, further improving the reliability of the connection between the calibration module 200 and the support module 100.

[0056] See Figure 2 The operating part 341 is driven to move along the first direction. The operating part 341 causes the elastic part 342 to deform, and the elastic part 342 accumulates elastic potential energy. The locking member 330 can be switched to the unlocked state. At this time, the operator can separate the first connecting member 310 and the second connecting member 320 or adjust the relative position between the first connecting member 310 and the second connecting member 320. When it is necessary to connect the first connecting member 310 and the second connecting member 320, the operator can release the driving force on the operating part 341. The elastic part 342 returns to its deformed state. Under the elastic force of the elastic part 342, the operating part 341 automatically moves to the second direction. The pushing inclined surface 3411 moves accordingly and pushes the locking member 330 in the opposite direction of the unlocking direction. The locking member 330 automatically switches to the locked state.

[0057] Specifically, see Figure 2The first connecting member 310 includes an outer connecting ring, and the second connecting member 320 includes an inner connecting ring. The outer connecting ring is sleeved on the outside of the inner connecting ring. The locking member 330 and the elastic operating member 340 are both at least partially movable within the inner cavity of the inner connecting ring. A first mounting seat 321 is provided on the inner wall of the inner connecting ring, and a mounting groove is provided on the first mounting seat 321. One end of the elastic part 342 is disposed in the mounting groove, and one end of the operating part 341 is connected to the other end of the elastic part 342. The other end of the operating part 341 moves through the inner connecting ring and the outer connecting ring, that is, the other end of the operating part 341 protrudes relative to the outer wall of the outer connecting ring. Pressing the other end of the operating part 341 in the first direction switches the locking member 330 from a locked state to an unlocked state.

[0058] In some embodiments, see Figure 2 The operating part 341 is provided with a first limiting part 343, which is located in the inner cavity of the inner connecting ring. When locked, the first limiting part 343 abuts against the inner wall of the inner connecting ring to limit the maximum displacement of the operating part 341 along the second direction, ensuring that the pushing slope 3411 can always contact the locking member 330.

[0059] For example, the elastic part 342 is a spring.

[0060] For example, see Figure 2 The operating part 341 includes a first operating lever, a conical block, and a second operating lever. One end of the first operating lever is connected to the elastic part 342, and the other end is connected to the conical block. One end of the second operating lever is connected to the conical block, and the other end moves through the inner connecting ring and the outer connecting ring, and abuts against the inclined surface 3411, which is the outer wall of the conical block.

[0061] In this embodiment, see Figure 1 and Figure 2 The first connector 310 or the second connector 320 is provided with an elastic element 350 connected to the locking element 330. The locking element 330 abuts against the pushing slope 3411 under the elastic force of the elastic element 350. Under the elastic force of the elastic element 350, the locking element 330 applies pressure to the pushing slope 3411 in the unlocking direction, so that the pushing slope 3411 exerts a force on the locking element 330 in the opposite direction to the unlocking direction. The locking element 330 can be stably maintained in the locked state under the action of this force, which further improves the reliability of the connection between the calibration module 200 and the support module 100.

[0062] See Figure 2In the locked state, the elastic member 350 deforms and exerts a spring force on the locking member 330 in the unlocking direction. Under the action of this spring force, the locking member 330 applies pressure on the pushing slope 3411 in the unlocking direction. At the same time, the locking member 330 is subjected to a reverse force from the pushing slope 3411. When the operating part 341 is driven to move in the first direction, the locking member 330 slides along the pushing slope 3411, the elastic member 350 gradually recovers its deformation, and the spring force of the elastic member 350 on the locking member 330 gradually decreases.

[0063] Specifically, see Figure 2 The first connecting member 310 includes an outer connecting ring, and the second connecting member 320 includes an inner connecting ring. The outer connecting ring is sleeved outside the inner connecting ring. The locking member 330 and the elastic operating member 340 are both at least partially movable within the inner cavity of the inner connecting ring. A second mounting seat 322 is provided on the inner wall of the inner connecting ring. The second mounting seat 322 is provided with a mounting hole. One end of the locking member 330 contacts the pushing inclined surface 3411, and the other end passes through the mounting hole. The elastic member 350 is disposed in the mounting hole and connected to the locking member 330.

[0064] For example, see Figure 2 The elastic element 350 is a spring, and the locking element 330 is provided with a second limiting part 331. The mounting hole is a stepped hole. One end of the elastic element 350 is connected to the stepped surface of the stepped hole, and the other end is connected to the second limiting part 331.

[0065] For example, the locking element 330 is a rod.

[0066] In some embodiments, see Figure 2 There are two locking elements 330 and two elastic elements 350, with each elastic element 350 corresponding to one locking element 330. The two locking elements 330 are symmetrically arranged on both sides of the elastic operating element 340. (See reference...) Figure 2 In terms of orientation, the unlocking direction of the upper locking member 330 is from top to bottom, and the unlocking direction of the lower locking member 330 is from bottom to top.

[0067] The elastic force of the elastic part 342 is greater than the sum of the elastic forces of the two elastic elements 350, so as to ensure that when the driving force on the operating part 341 is released, the operating part 341 can overcome the elastic forces of the two elastic elements 350 and move along the second direction under the action of the elastic force of the elastic part 342.

[0068] Optionally, see Figure 2The first connector 310 and the second connector 320 are provided with a locking groove 311, and the locking member 330 can be engaged or disengaged from the locking groove 311. When the locking member 330 is engaged in the locking groove 311, the locking member 330 is in a locked state, and the first connector 310 and the second connector 320 are reliably connected; when the locking member 330 is disengaged from the locking groove 311, the locking member 330 is in an unlocked state, and the first connector 310 and the second connector 320 are separated.

[0069] Specifically, see Figure 2 The first connecting member 310 includes an outer connecting ring, and the second connecting member 320 includes an inner connecting ring. The outer connecting ring is sleeved outside the inner connecting ring. The locking member 330 and the elastic operating member 340 are both at least partially movable within the inner cavity of the inner connecting ring. The locking groove 311 is located on the inner wall of the outer connecting ring. In the locked state, the locking member 330 passes through the inner connecting ring and engages in the locking groove 311, while the elastic member 350 accumulates elastic potential energy. When it is necessary to switch the locking member 330 to the unlocked state, the operating part 341 is pressed, causing the operating part 341 to move along the first direction. The elastic part 342 deforms, reducing the pushing force of the inclined surface 3411 on the locking member 330. Under the elastic force of the elastic member 350, the locking member 330 gradually moves away from the outer connecting ring along the unlocking direction. The locking member 330 gradually disengages from the locking groove 311; when it is necessary to switch the locking member 330 to the locked state, the pressure on the operating part 341 is released, and the operating part 341 automatically moves in the second direction under the elastic force of the elastic part 342. The pushing force of the pushing slope 3411 on the locking member 330 increases, and the locking member 330 gradually approaches the outer connecting ring in the opposite direction of the unlocking direction under the pushing force. The locking member 330 gradually gets stuck in the locking groove 311.

[0070] Optionally, see Figure 3 The support module 100 includes a support body 110, a support base 120, and a connecting component 130. The lower end of the support body 110 is detachably connected to the support base 120 via the connecting component 130, and the upper end of the support body 110 is connected to the first connecting member 310. The support body 110 and the support base 120 can also be disassembled and separated, which not only allows the support module 100 to be transported separately but also allows for flexible replacement of the support body 110 and the support base 120. This significantly improves the convenience of the support module 100 during movement, assembly, and maintenance, further ensuring the deployment flexibility and operational efficiency of the protective fence. In addition, this design allows for quick changes to the height of the protective fence by changing the length of the support body 110, expanding the versatility of the protective fence.

[0071] In this embodiment, see Figure 3The support base 120 is provided with multiple walking components 121, which are arranged at intervals along the circumference of the support base 120, so as to facilitate the flexible movement of the protective fence and improve the deployment flexibility and operation and maintenance efficiency of the protective fence.

[0072] Specifically, the walking component 121 includes casters, enabling the protective fence to move freely in any direction.

[0073] In some embodiments, the walking component 121 also includes a brake. When the protective fence is pushed or pulled to a predetermined position, the brake can be used to brake the casters, thereby keeping the protective fence stationary in the predetermined position. This improves the stability of the protective fence during use and effectively reduces the risk of tipping over due to external impact or uneven ground. When the protective fence needs to be moved, simply release the brake to allow the casters to return to a rotatable state.

[0074] In this embodiment, see Figure 2 and Figure 3 The connecting component 130 includes a third connector 131 and a fourth connector 132 that can be detachably connected. The third connector 131 is connected to the support base 120, and the fourth connector 132 is connected to the bottom of the support body 110. The connection method of the third connector 131 and the fourth connector 132 is the same as the connection method of the first connector 310 and the second connector 320, which will not be described again here.

[0075] In other embodiments, the connecting assembly 130 includes screwed bolts and nuts, and the support base 120 and the support body 110 are separably connected by bolts and nuts.

[0076] In this embodiment, see Figure 3 The support module 100 also includes a warning tape 111. The support body 110 is provided with a rotating shaft that can rotate around its own axis, and the warning tape 111 is wrapped around the rotating shaft. Pulling the warning tape 111 will unwrap the warning tape 111 from the rotating shaft and drive the rotating shaft to rotate. The warning tape 111 can achieve the effect of safety protection through physical marking.

[0077] For example, the support body 110 includes a support tube, and a rotating shaft is disposed in the inner cavity of the support tube. An opening is provided on the wall of the support tube, and a pull block is provided at the end of the warning tape 111, so that the staff can pull the warning tape 111 out of the opening by pulling the pull block.

[0078] In this embodiment, see Figure 3 The support body 110 is equipped with an operating handle 112, which allows staff to move the support body 110, making operation convenient and quick.

[0079] In this embodiment, a removable battery is installed on the support base 120. The battery is electrically connected to the control module and calibration module 200 and is configured to supply power to the control module and calibration module 200, so that the protective fence can be powered autonomously and is easy to use.

[0080] Specifically, see Figure 3 A sealing element 122 is provided on the support base 120, and the third connector 131 is sealed to the support base 120 through the sealing element 122 to prevent dust from affecting the normal use of the battery.

[0081] For example, the seal 122 is a rubber sealing ring that is vulcanized and bonded to the support base 120.

[0082] Optionally, see Figure 4 and Figure 5 The calibration module 200 includes a transmitter 210 and a receiver 220. The protective fence also includes a transmitter driver 510 and a receiver driver 520. Both the transmitter driver 510 and the receiver driver 520 are disposed on the second connector 320. The output end of the transmitter driver 510 is connected to the transmitter 210 and is used to drive the transmitter 210 to rotate around its own axis. The output end of the receiver driver 520 is connected to the receiver 220 and is used to drive the receiver 220 to rotate around its own axis. This arrangement allows the calibration module 200 to emit and receive calibration light independently without interference, which helps to improve the flexibility and convenience of calibration operations.

[0083] For example, the transmitter 210 is an infrared transmitter and the receiver 220 is an infrared receiver.

[0084] For example, the transmitting drive 510 is a motor or a disk, and the receiving drive 520 is a motor or a disk. When the transmitting drive 510 and / or the receiving drive 520 are disks, rotating the disk will drive the transmitting drive 210 or the receiving drive 220 to rotate.

[0085] In this embodiment, see Figure 4 and Figure 5 The protective fence also includes a mounting bracket 600, which includes a mounting base 610 disposed on the second connector 320 and a T-shaped bracket 620 disposed on the mounting base 610. The transmitter 210 and the receiver 220 are respectively mounted on the two ends of the flange of the T-shaped bracket 620. The transmitter 210 and the receiver 220 can rotate relative to the T-shaped bracket 620. The transmitter drive 510 and the receiver drive 520 are both disposed on the mounting base 610.

[0086] Specifically, the second connector 320 is sealed to the mounting base 610 to prevent dust from affecting the operation of the calibration module 200 and to improve the service life of the calibration module 200.

[0087] In this embodiment, see Figure 4 The mounting base 610 is provided with a charging port 611. The charging port 611 is electrically connected to the calibration module 200 and the control module via a wire. The charging port 611 is configured to supply power from an external power source to the calibration module 200 and the control module.

[0088] When the protective fence runs out of power, it can be recharged either by replacing the battery inside the support base 120 or by connecting an external power source to the charging port 611, which significantly improves the flexibility and convenience of recharging the protective fence.

[0089] In this embodiment, see Figure 4 and Figure 5 The mounting bracket 600 also includes a mounting top 630, on which a camera 631 electrically connected to the control module is mounted. The camera 631's shooting direction is the same as the direction of the calibration light emitted by the transmitter 210. Operators can visually obtain the direction of the calibration light's illumination through the content captured by the camera 631, further improving the convenience of calibration.

[0090] For example, the camera 631 employs a camera.

[0091] In this embodiment, see Figure 4 and Figure 5 A transparent protective cover 640 is provided on the mounting bracket 600, which covers the calibration module 200. Without affecting the calibration module 200's transmission and reception of calibration light, the transparent protective cover 640 effectively prevents dust or external debris from contacting the calibration module 200, thereby improving the service life and safety of the calibration module 200.

[0092] In an optional embodiment, the output of the transmitter driver 510 is directly connected to the transmitter 210, and the output of the receiver driver 520 is directly connected to the receiver 220.

[0093] In an optional embodiment, see [link to relevant documentation] Figure 4 and Figure 5The output end of the launch drive 510 is indirectly connected to the launcher 210, and the output end of the receiver drive 520 is indirectly connected to the receiver 220. Exemplarily, the protective fence also includes a meshing launch drive wheel 530 and a launch driven wheel 540. The launch driven wheel 540 is connected to the launcher 210, and the output end of the launch drive 510 is connected to the launch drive wheel 530 to drive the launch drive wheel 530 to rotate. The launch drive wheel 530 drives the launcher 210 to rotate via the launch driven wheel 540. The meshing of the teeth and the transmission ratio of the launch drive wheel 530 and the launch driven wheel 540 can optimize the power matching between the launch drive 510 and the launcher 210, improving the stability of the launcher 210's rotation. The protective fence also includes a meshing receiving drive wheel 550 and a receiving driven wheel 560. The receiving driven wheel 560 is connected to the receiving component 220, and the output end of the receiving drive component 520 is connected to the receiving drive wheel 550 to drive the receiving drive wheel 550 to rotate. The receiving drive wheel 550 drives the receiving component 220 to rotate through the receiving driven wheel 560. The meshing of the receiving drive wheel 550 and the receiving driven wheel 560, along with the adjustment of the transmission ratio, can optimize the power matching between the receiving drive component 520 and the receiving component 220, thereby improving the stability of the rotation of the receiving component 220.

[0094] In this embodiment, see Figure 5 The direction of the self-axis of the launching component 210 and the vertical direction ( Figure 5 The Z-direction of the receiver 220 is parallel to the vertical direction. The output end of the transmitter drive 510 extends horizontally. Both the transmitter drive wheel 530 and the transmitter driven wheel 540 are bevel gears. The axis of the receiver 220 is parallel to the vertical direction. The output end of the receiver drive 520 extends horizontally. Both the receiver drive wheel 550 and the receiver driven wheel 560 are bevel gears.

[0095] In other embodiments, the axial direction of the transmitter 210 is parallel to the output direction of the transmitter drive 510, and both the transmitter drive wheel 530 and the transmitter driven wheel 540 are circular gears; the axial direction of the receiver 220 is parallel to the output direction of the receiver drive 520, and both the receiver drive wheel 550 and the receiver driven wheel 560 are circular gears.

[0096] Optionally, see Figure 4 and Figure 5The control module includes a control switch 410, a control circuit board 420, and a transmission circuit board. The control switch 410, the control circuit board 420, and the transmission circuit board are all electrically connected to the calibration module 200. The control switch 410 is located on the second connector 320 and is configured to control the opening and closing of the calibration module 200. The transmission circuit board is electrically or communicatively connected to the control circuit board 420 and is configured to transmit the intensity value of the received calibration light to the control circuit board 420. The control circuit board 420 is configured to control the rotation of the calibration module 200 and record the intensity value of the received calibration light.

[0097] For example, see Figure 4 and Figure 5 The control circuit board 420 and the transmission circuit board are both mounted on the T-shaped bracket 620, and the control switch 410 is mounted on the mounting base 610.

[0098] In this embodiment, the control circuit board 420 adopts an integrated main control chip (such as a microcontroller). The main control chip is responsible for processing the data transmitted from the transmission circuit board, running the control algorithm, and controlling the rotation angle of the calibration module 200.

[0099] Specifically, both the transmitting drive unit 510 and the receiving drive unit 520 are motors. The control circuit board 420 is electrically connected to both the transmitting drive unit 510 and the receiving drive unit 520. The control circuit board 420 controls the rotation angle of the transmitting unit 210 and the receiving unit 220 by controlling the starting and stopping of the motors.

[0100] In this embodiment, both the transmitter 210 and the receiver 220 are infrared devices, and the calibration light is infrared light. The transmission circuit board can quantify the intensity of the received calibration light signal in real time and convert it into a digital signal or an electrical signal to feed back to the control circuit board 420.

[0101] In this embodiment, the control module also includes a communication component. Multiple protective fences are connected to each other through the communication component, enabling them to communicate with each other and form a local area network, thereby improving the convenience for staff to control multiple protective fences.

[0102] For example, the communication device includes, but is not limited to, long-range radio or narrowband Internet of Things.

[0103] Example 2

[0104] like Figure 6 As shown, this embodiment provides a protective fence calibration method for calibrating the emission direction of the calibration light of the protective fence in Embodiment 1. The protective fence has multiple sections spaced apart along the protection direction.

[0105] The method for calibrating this protective fence includes the following steps:

[0106] S1. The calibration module 200 is activated using the control module, and the protective fence adjacent to the protective fence to be calibrated receives the calibration light emitted by the protective fence to be calibrated.

[0107] In this embodiment, the following steps are included before step S1: assembling the protective fence. Specifically, a support body 110 of appropriate length is selected, and the support body 110 is connected to the support base 120 using the connecting component 130, and the control module is connected to the support body 110 using the connecting module 300; then, the universal wheels are braked using the brake unit, so that the protective fence remains stationary in the predetermined position.

[0108] S2. The control module drives the corresponding calibration module 200 to rotate, changing the direction of the calibration light emitted by the protective fence to be calibrated and changing the intensity of the calibration light received by the adjacent protective fence.

[0109] Specifically, the control module of the protective fence to be calibrated activates the corresponding transmitting drive 510, which drives the corresponding transmitting component 210 to rotate, changing the direction of the calibration light emitted to the adjacent protective fence. Simultaneously, the control module of the adjacent protective fence activates the corresponding receiving drive 520, which drives the corresponding receiving component 220 to rotate, changing the range of the receiving component 220 illuminated by the calibration light. This changes the intensity of the calibration light received by the adjacent protective fence, and the control module of the adjacent protective fence can record the range of change in the intensity value of the received calibration light in real time.

[0110] In this embodiment, the control module controls the transmitting drive 510 to drive the transmitting element 210 to rotate within a first preset angle range, and controls the receiving drive 520 of the adjacent protective fence to drive the corresponding receiving element 220 to rotate within a second preset angle range. Due to the influence of the mounting bracket 600, both the rotation of the transmitting element 210 and the rotation of the receiving element 220 have blind zones. When the rotating position of the transmitting element 210 is not within the first preset angle range, the transmitting element 210 rotates into the blind zone. At this time, no matter how the transmitting element 210 rotates, the receiving element 220 of the adjacent protective fence will not receive the calibration light. Similarly, when the rotating position of the receiving element 220 is not within the second preset angle range, the receiving element 220 rotates into the blind zone. At this time, no matter how the receiving element 220 rotates, it will not receive the calibration light.

[0111] S3. Determine the calibration position of the calibration module 200 of the protective fence to be calibrated when the intensity of the calibration light recorded by the control module of the adjacent protective fence is the maximum.

[0112] Specifically, during the rotation of the transmitter 210 of the protective fence to be calibrated and the receiver 220 of the adjacent protective fence, the control module of the adjacent protective fence records the intensity of the calibration light it receives in real time. Based on the intensity data recorded by the control module of the adjacent protective fence, the moment when the calibration light received by the receiver 220 of the adjacent protective fence is strongest can be determined. At this strongest moment, the position of the transmitter 210 of the protective fence to be calibrated is the final position it needs to rotate to, i.e., its calibration position, and the position of the receiver 220 of the adjacent protective fence is also the final position it needs to rotate to, i.e., its calibration position.

[0113] Among them, when the straight line between the transmitter 210 of the protective fence to be calibrated and the receiver 220 of the adjacent protective fence is collinear with the emitted calibration light, the intensity of the calibration light received by the adjacent protective fence is the greatest.

[0114] S4. Determine whether the calibration module 200 of the protective fence to be calibrated and the calibration module 200 of the adjacent protective fence are both in the calibration position. If yes, then complete the calibration of the emission direction of the calibration light of the protective fence to be calibrated. If not, drive the calibration module 200 of the two adjacent protective fences that is not in the calibration position to rotate until the calibration modules 200 of the two adjacent protective fences are both rotated to the calibration position.

[0115] After step S2, the position where the transmitter 210 of the protective fence to be calibrated stops may be its calibration position or it may not be in its calibration position; similarly, the position where the receiver 220 of the adjacent protective fence stops may be its calibration position or it may not be in its calibration position. Therefore, when performing step S4, it is first determined whether the transmitter 210 of the protective fence to be calibrated is in its calibration position, and whether the receiver 220 of the adjacent protective fence is in its calibration position.

[0116] Specifically, it is determined whether the transmitter 210 of the protective fence to be calibrated is in the calibration position. If so, the position calibration of the transmitter 210 is completed; otherwise, the control module of the protective fence to be calibrated drives the corresponding transmitter 210 to rotate until it reaches the calibration position, thus completing the automatic calibration of the transmitter 210's position. It is also determined whether the receiver 220 of the adjacent protective fence is in the calibration position. If so, the position calibration of the receiver 220 of the adjacent protective fence is completed; otherwise, the control module of the adjacent protective fence drives the corresponding receiver 220 to rotate until it reaches the calibration position, thus completing the automatic calibration of the receiver 220's position. When both the transmitter 210 of the protective fence to be calibrated and the receiver 220 of the adjacent protective fence are in the calibration position, the calibration direction calibration of the calibration light emitted by the protective fence to be calibrated is completed.

[0117] In this embodiment, multiple protective fences are arranged at intervals along the protection direction. The calibration process of the emission direction of the calibration light of any protective fence can be performed according to the above steps S1 to S4. The calibration operations of multiple protective fences can be carried out simultaneously or one by one.

[0118] The protective fence calibration method according to this embodiment calibrates the position of the protective fence and can automatically find the optimal emission direction of the calibration light. The alignment accuracy reaches the level of machine vision, far exceeding the manual adjustment of the human eye, and minimizes false alarms and missed alarms caused by misalignment from the root.

[0119] Optionally, the following steps may be included after step S4:

[0120] S5. After the preset working time of the protective fence, the control module determines whether the transmitter 210 and receiver 220 are both in the calibration position. If yes, the operation continues; otherwise, the control module controls the transmitter drive 510 to rotate the transmitter 210 and / or controls the receiver drive 520 to rotate the receiver 220 until both the transmitter 210 and receiver 220 are in the calibration position. This operation enables self-checking of the protective fence operation, improves the long-term stability of the protective fence, and ensures the protective effect.

[0121] In this embodiment, the protective fence also includes an alarm device that is electrically or communicatively connected to the control module. When the transmitter 210 and / or receiver 220 cannot be rotated to the calibration position, the alarm device will sound an alarm to remind staff to intervene manually in a timely manner, effectively changing the passive response to an active warning, and greatly improving the operation and maintenance efficiency and reliability of the protective fence.

[0122] For example, when the entire protective fence is moved or knocked down, the control module is severely obscured by dirt, or the control module suffers hardware damage, the transmitter 210 and / or receiver 220 may be unable to rotate to the calibration position.

[0123] In some embodiments, during the protection process, when the receiver 220 cannot receive the calibration light emitted by the transmitter 210 of the adjacent protective fence, it indicates that an external person has entered the area protected by the protective fence. At this time, the alarm will also sound an alarm to remind the staff in time, thus realizing the automatic protection function of the protective fence.

[0124] Optionally, the protective fence also includes a terminal control device (such as computer software or mobile phone software). After the control module is connected to the support body 110, the terminal control device communicates with the control module. At this time, the staff can remotely control the adjustment of the positions of multiple protective fences through the terminal control device.

[0125] Specifically, before step S1, staff can send a calibration start command to the protective fence to be calibrated through the terminal control device; after step S4, staff can receive calibration completion information through the terminal control device; in step S5 and during the use of the protective fence, the alarm signal issued by the alarm device can be transmitted to the staff through the terminal control device.

[0126] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
