[0025] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0026] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0027] Figure 1 Structural schematic diagram of a safety protection device provided by an embodiment of the present invention. This embodiment is applicable to an application scenario where a pedestrian passage and a mobile device passage are cross-arranged. Among them, the pedestrian passage can be understood as a passage for workshop operators to pass through; the mobile device passage can be understood as a passage for mobile devices (such as finished vehicles or handling trolleys) to pass through.

[0028] See Figure 1 As shown, the safety protection device of the present application includes: a guardrail 100, a driving component 200, a detection and interaction module 300, and a control module 400.

[0029] The guardrail 100 of the present application is fixed at a position adjacent to the pedestrian passage and the mobile device passage by a rotating shaft, and the guardrail 100 can rotate horizontally around the rotating shaft. The height of the guardrail 100 in the vertical direction is set according to the average height of mobile devices and operators, and no specific limitation is imposed thereon.

[0030] The driving component 200 of the present application is in transmission connection with the guardrail 100 to drive the guardrail 100 to move horizontally between a first limit position and a second limit position. Among them, when the guardrail 100 moves to the first limit position, it can intercept the pedestrian passage, and when the guardrail 100 moves to the second limit position, it can intercept the mobile device passage. In this embodiment, the pedestrian passage and the mobile device passage are arranged in a cross manner. Typically, the pedestrian passage and the mobile device passage are perpendicular to each other, that is, at a 90° angle. Correspondingly, when the guardrail 100 moves between the first limit position and the second limit position, it needs to rotate a corresponding angle (for example, rotate 90° clockwise or counterclockwise).

[0031] The detection and interaction module 300 of the present application is used to synchronously obtain the first interaction data of the pedestrian passage and the second interaction data of the mobile device passage, and obtain the limit feedback signal of the guardrail 100. Among them, the first interaction data can be understood as the data representing whether there are pedestrians passing through the pedestrian passage. The first interaction data can be the command data issued by the operator, or the data collected by the detection element; the second interaction data can be understood as the data representing whether there are mobile devices passing through the mobile device passage. The second interaction data can be the command data issued by the mobile device driver, or the data collected by the detection element; the limit feedback signal can be understood as the signal representing that the guardrail 100 reaches a specific position. Typically, the detection and interaction module 300 includes but is not limited to: optical detection elements, image detection elements, and switch elements. Among them, the switch elements include but are not limited to: manual switches such as buttons and knobs, or limit switches. Specifically, different types of elements can be set in the detection and interaction module 300, and the installation angles and quantities of different elements can be adaptively adjusted, which can improve the detection accuracy of pedestrians and mobile devices.

[0032] The control module 400 is respectively connected to the detection and interaction module 300 and the driving component 200, and is used to determine the driving control signal according to the first interaction data, the second interaction data, and the limit feedback signal, and control the driving component 200 to act according to the driving control signal to switch the guardrail 100 to the first limit position or the second limit position; among them, the priority of the first interaction data is higher than the priority of the second interaction data.

[0033] In this embodiment, "the priority of the first interaction data is higher than that of the second interaction data" means that when the driving control strategies corresponding to the first interaction data and the second interaction data are inconsistent, the driving control strategy corresponding to the first interaction data is preferentially used to control the operation of the driving component 200. For example, when it is determined according to the first interaction data that a pedestrian passes through the pedestrian passage, and at the same time it is determined according to the second interaction data that a mobile device passes through the mobile device passage, the control strategy when a pedestrian passes through the pedestrian passage is preferentially executed, and the guardrail 100 is switched to the second limit position. It should be noted that when it is determined according to the first interaction data that no pedestrian passes through the pedestrian passage, and at the same time it is determined according to the second interaction data that no mobile device passes through the mobile device passage, the guardrail 100 is also switched to the second limit position to ensure the priority passage of the pedestrian passage.

[0034] Specifically, the guardrail 100 can move between the first limit position and the second limit position under the drive of the driving component 200. The control module 400 receives the first interaction data of the pedestrian passage and the second interaction data of the mobile device passage in real time. When it is determined that a pedestrian passes through the pedestrian passage, the driving component 200 is controlled to act, and the guardrail 100 is driven to move to the second limit position until the limit feedback signal corresponding to the second limit position is received, successfully intercepting the mobile device passage; when it is determined that no pedestrian passes through the pedestrian passage and a mobile device passes through the mobile device passage, the driving component 200 is controlled to act, and the guardrail 100 is driven to move to the first limit position until the limit feedback signal corresponding to the first limit position is received, successfully intercepting the pedestrian passage. By collecting the interaction data of the pedestrian passage and the mobile device passage, the detection accuracy of vehicles and pedestrians is improved, and the guardrail is combined to effectively separate the human and vehicle passages, solving the problem that the existing finished vehicle production area lacks effective protection measures for the passage of staff and has poor safety, and can improve the safety of the finished vehicle workshop operation.

[0035] Optionally, Figure 2 is a schematic structural diagram of a detection interaction module provided by an embodiment of the present invention. Refer to Figure 2As shown in the figure, the detection interaction module 300 of the present application includes: a human body detection unit 301, a mobile device detection unit 302, and a limit switch. Among them, the detection range of the human body detection unit 301 is set based on the walkway width of the pedestrian passage and human engineering data (including but not limited to the average height of operators and the walking trajectories of operators), and the detection element feeds the pedestrian detection data as the first interaction data to the control module 400; the detection range of the mobile device detection unit 302 is set based on the lane width of the mobile device passage and device morphology data, and the mobile device detection unit 302 feeds the device detection data as the second interaction data to the control module 400; the limit switch includes a first limit switch 303A and a second limit switch 303B. The first limit switch 303A is set at the first limit position, and the second limit switch 303B is set at the second limit position. The trigger signals of the first limit switch 303A and the second limit switch 303B are fed back to the control module 400 as the limit feedback signal.

[0036] Optionally, the human body detection unit 301 includes at least one of the following: a photodetector, an optical sensor, or an image acquisition unit; the mobile device detection unit 302 includes at least one of the following: a photodetector, an optical sensor, or an image acquisition unit. Preferably, the human body detection unit 301 uses a photodetector, and the mobile device detection unit 302 uses a camera.

[0037] Specifically, the human body detection unit 301 is provided with at least one type of detection element (such as a photodetector, an optical sensor, or an image acquisition unit). The number and installation angle of the detection element are adaptively adjusted based on the walkway width of the pedestrian passage and human engineering data (including but not limited to the average height of operators and the walking trajectories of operators), and no specific limitation is imposed thereon. Similarly, the mobile device detection unit 302 is provided with at least one type of detection element (such as a photodetector, an optical sensor, or an image acquisition unit). The number and installation angle of the detection element are adaptively adjusted based on the lane width of the mobile device passage and device morphology data, and no specific limitation is imposed thereon. Taking the human body detection unit 301 using a photodetector as an example, multiple groups of laser pair detectors can be set on the handrails on both sides of the pedestrian passage, and the first interaction data is the high and low level signals emitted by the laser pair detectors. Taking the mobile device detection unit 302 using a camera as an example, at least one camera can be set at the intersection of the pedestrian passage and the mobile device passage, and the camera faces the direction of the mobile device, and the second interaction data is the image data collected by the camera.

[0038] Optionally, the control module 400 is configured to: determine whether there is a pedestrian passing through the pedestrian passage according to the first interaction data, and when there is a pedestrian passing through the pedestrian passage, output a first drive control signal to switch the guardrail 100 to the second limit position until the limit feedback signal of the second limit position is received; when there is no pedestrian passing through the pedestrian passage, determine whether there is a mobile device passing through the mobile device passage according to the second interaction data, and when there is a mobile device passing through the mobile device passage, output a second drive control signal to switch the guardrail 100 to the first limit position until the limit feedback signal of the first limit position is received.

[0039] Optionally, the control module 400 is further configured to: when switching the guardrail 100 to the second limit position, determine the measured distance between the mobile device and the second limit position according to the second interaction data, and adjust the duty cycle of the drive control signal according to the measured distance to adjust the moving speed of the guardrail 100.

[0040] Specifically, the control module 400 preferentially determines whether there is a pedestrian passing through the pedestrian passage according to the first interaction data. When there is a pedestrian passing through the pedestrian passage, it outputs a first drive control signal to control the driving component 200 to act forward, driving the guardrail 100 to move towards the second limit position. At the same time, it determines the measured distance between the mobile device and the second limit position according to the second interaction data, and adjusts the duty cycle of the second drive control signal according to the measured distance to adjust the moving speed of the guardrail 100 until the limit feedback signal corresponding to the second limit position is received, successfully intercepting the mobile device passage; when there is no pedestrian passing through the pedestrian passage, it determines whether there is a mobile device passing through the mobile device passage according to the second interaction data. When there is a mobile device passing through the mobile device passage, it outputs a second drive control signal to control the driving component 200 to act reversely, driving the guardrail 100 to move towards the first limit position until the limit feedback signal corresponding to the first limit position is received, successfully intercepting the pedestrian passage. By setting the priority of the interaction data of the pedestrian passage higher than that of the interaction data of the mobile device passage, the passage of the pedestrian passage and the safety of pedestrians are preferentially guaranteed; when there is a pedestrian passing through, by performing closed-loop adjustment on the moving speed of the guardrail, the safe separation of people and vehicles under different working conditions is realized, and the safety of the finished product workshop operation is improved.

[0041] Optionally, Figure 3 Another structural schematic diagram of the detection interaction module provided by the embodiment of the present invention. Refer to Figure 3As shown in the figure, the detection interaction module 300 of the present application includes: a human body detection unit 301, a changeover switch 304, and a limit switch; the human body detection unit 301 is provided with at least one type of detection element, and the detection range of the detection element is set based on the walkway width of the pedestrian passage and human engineering data, and the pedestrian detection data is fed back to the control module 400 as the first interaction data; the changeover switch 304 is arranged in the control cabinet and is used to obtain an active switching signal and feed back the active switching signal to the control module 400 as the second interaction data; the limit switch includes a first limit switch 303A and a second limit switch 303B, the first limit switch 303A is arranged at a first limit position, the second limit switch 303B is arranged at a second limit position, and the trigger signals of the first limit switch 303A and the second limit switch 303B are fed back to the control module 400 as limit feedback signals.

[0042] Optionally, the control module 400 is further configured to: when receiving the active switching signal, determine whether there is a pedestrian passing through the pedestrian passage according to the first interaction data, and when there is no pedestrian passing through the pedestrian passage, output a second drive control signal to switch the guardrail 100 to the first limit position until receiving the limit feedback signal of the first limit position.

[0043] Specifically, when there is no pedestrian and no mobile device, the guardrail 100 is located at the second limit position to ensure the priority of the pedestrian passage. When the finished vehicle travels to the guardrail 100, the driver can send an active switching signal through the changeover switch 304. After the control module 400 receives the active switching signal, it determines whether there is a pedestrian passing through the pedestrian passage according to the first interaction data. When there is a pedestrian passing through the pedestrian passage, the guardrail 100 remains in its current position; when there is no pedestrian passing through the pedestrian passage, the control module 400 outputs a second drive control signal to control the driving component 200 to act in the reverse direction, driving the guardrail 100 to move to the first limit position until receiving the limit feedback signal corresponding to the first limit position, and successfully intercepting the pedestrian passage. By setting the priority of the interaction data of the pedestrian passage higher than that of the mobile device passage, the priority of the pedestrian passage and the safety of pedestrians are guaranteed; when there is no pedestrian passing through and the mobile device needs to pass, the guardrail is controlled to move to achieve the safe separation of people and vehicles under different working conditions and improve the safety of the finished vehicle workshop operation.

[0044] Figure 4 It is a schematic diagram of the installation structure of a safety protection device provided by an embodiment of the present invention. In Figure 4 the embodiment shown, the arrow indicates the passing direction of the mobile device, S1 represents the first limit position, and S2 represents the second limit position. Refer to Figure 4As shown, the driving component 200 of the present application includes: a driving motor 201, a driving circuit 202 and an interlocking circuit 203; the driving motor 201 is transmission-connected to the guardrail 100; the driving circuit 202 is used to control the driving motor 201 to rotate forward or reverse according to a driving control signal; the interlocking circuit 203 is used to interlock the forward control circuit and the reverse control circuit of the driving motor 201.

[0045] Optionally, the drive circuit 202 may adopt an H-bridge drive circuit, which is composed of four switch elements (such as MOSFETs or transistors), and the direction of the current is changed by controlling the on and off of these switches, thereby realizing the forward and reverse rotation of the motor. In some embodiments, a dedicated H-bridge driver chip (such as L298N, L293D) can be used to simplify the circuit design. In some embodiments, a protection diode can also be set in the drive circuit 202, and a freewheeling diode is connected in parallel at both ends of each switch element to prevent the reverse voltage generated when the switch is switched from damaging the element.

[0046] Optionally, the interlock circuit 203 may be provided with at least two relays, such as a first relay and a second relay, wherein the normally open contact of the first relay and the normally closed contact of the second relay are provided in the forward control circuit of the drive motor 201, and the normally open contact of the second relay and the normally closed contact of the first relay are provided in the reverse control circuit of the drive motor 201, so as to avoid the forward control circuit and the reverse control circuit being turned on at the same time. For example, see Figure 4 As shown, when the forward control circuit of the driving motor 201 is turned on, the driving circuit 202 drives the guardrail 100 to move to the second limit position S2 until a limit feedback signal corresponding to the second limit position S2 is received, thereby successfully intercepting the mobile device channel; when the reverse control circuit of the driving motor 201 is turned on, the driving circuit 202 drives the guardrail 100 to move to the first limit position S1 until a limit feedback signal corresponding to the first limit position S1 is received, thereby successfully intercepting the pedestrian channel.

[0047] Figure 5 A schematic diagram of another safety protection device provided by an embodiment of the present invention is shown in FIG. Figure 5 As shown, the safety protection device of the present application further includes: a timing unit 500, which is connected to the control module 400. The control module 400 is further configured to: after detecting that a mobile device passes through the mobile device channel, control the timing unit 500 to start timing, and when the timing time reaches a preset time, control the driving component 200 to operate and switch the guardrail 100 to the second limit position.

[0048] In this embodiment, the preset time can be understood as the waiting time for the mobile device to completely pass through the position where the guardrail 100 is located, and its specific value is not limited. By setting a timing unit, the delay protection of the guardrail displacement control is realized, avoiding collisions between the guardrail and the mobile device, and improving the safety and reliability of the device.

[0049] Figure 6 FIG. is a schematic structural diagram of another safety protection device provided by an embodiment of the present invention. Refer to Figure 6 As shown, the safety protection device of the present application further includes: a warning unit 600 and / or a communication unit 700; the warning unit 600 is connected to the control module 400, and the warning unit 600 is arranged within the visible range of the mobile device passage. The control module 400 is further configured to: when detecting a pedestrian or a mobile device, control the warning unit 600 to issue a warning; the communication unit 700 is connected to the control module 400, and the communication unit 700 is used to send at least one of the first interaction data, the second interaction data, the limit feedback signal, and the warning signal to the terminal device.

[0050] Optionally, the warning unit 600 includes but is not limited to at least one of the following: a warning light, a buzzer, and a graphic display.

[0051] Optionally, the terminal device includes but is not limited to at least one of the following: mobile terminals such as smart phones, smart wearable devices, and laptop computers, desktop computers, and servers.

[0052] Specifically, when the control module 400 detects that a pedestrian passes through the pedestrian passage, it controls the warning unit 600 to issue a first warning (such as a sound and light warning or a graphic warning) to remind the driver in the mobile device passage to pay attention and avoid the pedestrian; when the control module 400 detects that a mobile device passes through the mobile device passage, it controls the warning unit 600 to issue a second warning (such as a sound and light warning or a graphic warning) to remind the pedestrian to wait, improving the safety protection performance. By setting a remote communication function, the remote observation and recording of data and communication status are realized.

[0053] Based on the above embodiment, the embodiment of the present invention further provides a control method for a safety protection device, which is implemented based on the above safety protection device and has the corresponding control strategy and beneficial effects of the safety protection device.

[0054] In this embodiment, the safety protection device includes a guardrail, and the guardrail can move between a first limit position and a second limit position. The first limit position is used to intercept the pedestrian passage, and the second limit position is used to intercept the mobile device passage.

[0055] Figure 7 FIG. is a flowchart of a control method for a safety protection device provided by an embodiment of the present invention. As Figure 7As shown in the figure, the control method of the safety protection device includes the following steps:

[0056] S1: Synchronously obtain the first interaction data of the pedestrian passage and the second interaction data of the mobile device passage, and obtain the limit feedback signal of the guardrail.

[0057] S2: Determine the drive control signal according to the first interaction data, the second interaction data and the limit feedback signal, and control the drive component to act according to the drive control signal, and switch the guardrail to the first limit position or the second limit position.

[0058] Among them, the priority of the first interaction data is higher than that of the second interaction data.

[0059] Optionally, determining the drive control signal according to the first interaction data, the second interaction data and the limit feedback signal, and controlling the drive component to act according to the drive control signal to switch the guardrail to the first limit position or the second limit position includes: determining whether there are pedestrians passing through the pedestrian passage according to the first interaction data.
