[0045] A communication interface 15 is arranged outside the protective housing 11. The controller 5 is connected to the custom control component 2 and the operating device switch 6 through the communication interface 15, where the operating device switch 6 includes one or more of the emergency stop switch and the power supply switch of the operating device;

[0047] As an alternative implementation method, the three-dimensional protection sensor 1 is connected to the custom control component 2 through a USB data cable;

[0048] As another alternative implementation method, the communication interface is two LAN interfaces, and the three-dimensional protection sensor 1 is connected to the custom control component 2 and the power supply switch or the emergency stop switch of the operating device through a LAN data cable;

[0049] As another alternative implementation method, the communication interface 15 includes a USB interface and a LAN interface. The user can select an interface to connect the three-dimensional protection sensor 1 to the custom control component 2 according to different usage requirements and habits, and the two connection methods provide alternatives, that is, even if one of them cannot be used, the other can be used for connection; an external signal line is connected to the operating device switch 6 through the LAN interface;

[0050] In this embodiment, the communication interface 15 includes a USB interface and two LAN interfaces.

[0051] Further, as Figure 4 shown, the infrared lens assembly 3 includes an infrared lens emitter group 31 and an infrared lens receiver group 32;

[0052] The infrared lens emitter group 31 includes several infrared lens emitters 33 for emitting infrared light beams, and the several infrared lens emitters 33 are respectively connected to the input end of the controller 5;

[0053] The infrared lens receiver group 32 includes several infrared lens receivers 34 for collecting infrared light beams in real time, for collecting real-time information of received infrared light, and the several infrared lens receivers 34 are respectively connected to the input end of the controller 5, and transmit the collected information parameters circuit to the controller 5.

[0054] Further, the indication and warning component 4 includes an indicator light group 41 and a buzzer 42 (as Figure 5 shown).

[0055] Further, the controller 5 includes an information acquisition module 51, a signal conversion and operation module 52, and a control signal output module 53 (as Figure 6 shown);

[0056] The input end of the information acquisition module 51 is circuit-connected to the infrared lens assembly 3 to collect real-time parameter information of the infrared light beam; the output end of the information acquisition module 51 is connected to the control signal output module 53 through the signal conversion and operation module 52, and converts the collected parameter information into a control electrical signal after calculation;

[0057] The output end of the control signal output module 53 is connected to the indication and warning component 4 to control the working state of the indication and warning component 4 according to the type of the control signal.

[0058] Preferably, the controller 5 further includes a filtering module 54, which can filter and shield interference signals.

[0059] Further, the custom regulation component 2 includes an external computer 21 and a hardware input device 22, and the hardware input device 22 is connected to the external computer 21 for adjusting and customizing the detection range;

[0060] As an alternative implementation, the hardware input device 22 includes a keyboard and a mouse, and is line-connected to the external computer 21;

[0061] As another alternative implementation, the hardware input device 22 includes a keyboard and a mouse, and is Bluetooth-connected to the external computer 21;

[0062] In this embodiment, the Bluetooth connection method is adopted, which is not limited by short distance and is convenient to operate;

[0063] The external computer 21 is connected to the communication interface 12 by wire, and the range of the protection detection area displayed on the external computer 21 is custom-set and adjusted through the hardware input device 22.

[0064] Furthermore, the protection housing is provided with a power switch 14, which is connected to the infrared lens assembly 3, the indication and warning assembly 4, and the controller 5; it is used to turn on and off the adjustment function of the three-dimensional protection sensor 1. As an alternative, the power switch 14 is a push-button type. Pressing the power switch 14 supplies power to the three-dimensional protection sensor 1, and the indicator light group 41 lights up to display the operating state, and the infrared lens assembly 3, the indication and warning assembly 4, and the controller 5 work; pressing the power switch 14 again to turn it off stops the power supply, and each component stops operating.

[0065] As another alternative, the power switch 14 is a rotary type. Rotating the power switch 14 switches to the on or off state, thereby controlling the power supply to turn on or off.

[0066] Both are relatively common power switches 14. In this embodiment, the rotary power switch 14 is selected.

[0067] In this embodiment, in order to facilitate operation and not affect the divergence of the light beam, the power switch 14 is arranged on one side of the protection housing 11 away from the infrared lens assembly 3.

[0068] Furthermore, the protection housing 1 is made of aviation aluminum material, making it lightweight and high-strength.

[0069] Furthermore, the infrared lens assembly 3 includes a high-power infrared laser emitter group 31 and an infrared laser receiver group 32 with a wavelength of 850 nm.

[0070] Embodiment 2

[0071] The following is how the three-dimensional protection sensor provided in this embodiment is used:

[0072] When in use, the assembled three-dimensional protection sensor 1 is connected to the external computer 21 through the communication interface 12. Rotate the power switch 14 to start the three-dimensional protection sensor 1, and the indicator light group 41 lights up, indicating the power-on state.

[0073] Start the infrared lens emitter group 31. Multiple infrared lens emitters 33 emit infrared light. Under the action of different angles, the light beam diverges outward to form a projection plane. The space between the starting end of the light beam and the irradiated projection plane is set as the predetermined space to be monitored.

[0074] The infrared receiver group 32 collects and transmits in real time the parameter information such as the divergence direction and divergence length of each light beam in the infrared lens emitter group 31 to the controller 5, and then transmits the information to the external computer 2 through the communication interface 12, and displays the integrated information of the light beams, and synchronously outputs the 3D contour map obtained by the divergence of multiple light beams at different angles and the depth-of-field map formed by different light beam divergence distances;

[0075] Both the manager and the operator can perform custom editing on the light beam information through the external computer 21 connected to the three-dimensional protection sensor 1 via the communication interface 12. Specifically, by using the input hardware 22 (including the keyboard and mouse) to select several light beams, the space between the emitting ends of the selected several light beams and the illuminated surface projected after divergence is the set monitoring space;

[0076] The infrared receiver group 32 collects and transmits in real time the parameter information such as the divergence direction and divergence length of each light beam in the infrared lens emitter group 31 to the controller 5 for internal calculation by the controller 5;

[0077] When there is no abnormality in the monitoring space and the monitoring value is within the set range, it is in a safe state;

[0078] The indicator light group 41 is determined to be in a dangerous state when there are foreign personnel or foreign objects entering the monitoring space or the monitoring value exceeds the set monitoring range; at least two indicator lights are included in the indicator light group 41, which are displayed in different colors respectively. For example, the safety indicator light is green and the dangerous state indicator light is red;

[0079] At this time, as an implementable method, when in a dangerous state, the safety indicator light goes out and the dangerous indicator light lights up, and the state of the monitoring area is distinguished by the color of the indicator light;

[0080] As another alternative implementation method, when in a dangerous state, the safety indicator light goes out and the dangerous indicator light flashes, and the state of the monitoring area is distinguished by the color of the indicator light and further warned by the flashing;

[0081] The buzzer 42 generates a buzzer warning sound to indicate that it is in a dangerous state at this time, and the personnel who break into this area need to evacuate quickly and the foreign object needs to be removed.

[0082] During the production and manufacturing process, the controller 5 is also connected to the emergency stop switch of the equipment operating in the monitoring area. When in a dangerous state, the circuit controls the emergency stop switch to pause the equipment to avoid harming the intruding personnel and avoiding the impact of foreign objects on the production process.

[0083] It can be widely applied to various application scenarios such as injection molding machine mold production operations, safety area protection, AGV / forklift obstacle recognition and emergency stop, and personnel and material flow recognition.

[0084] Embodiment 3

[0085] As Figure 8 shown, the operation method of the protection monitoring system based on the three-dimensional protection sensor includes the following steps:

[0086] S1: Number a plurality of infrared lens emitters 33 and infrared lens receivers 34 respectively through the custom regulation component 2; for example, there are 50 infrared lens emitters 33 and 50 infrared lens receivers 34, and label them as 1-50 and 51-100 respectively.

[0087] S2: Start the protection monitoring system, and the controller 5 collects the light source angles and depth information of a plurality of infrared lens emitters 33 and a plurality of infrared lens receivers 34, and transmits them to the external computer 21 to form a three-dimensional contour map and a depth-of-field map;

[0088] S3: Adjust the detection area boundary through the hardware input device 22, and only receive the light angles and depth information of a plurality of infrared lens emitters 33 and infrared lens receivers 34 within the monitoring area to form a three-dimensional contour map and a depth-of-field map of the monitoring area; in this step, the label range of the infrared lens emitters 33 or the external lens receivers 34 within the area to be monitored can be input through the keyboard. For example, input the monitoring range as the infrared lens emitters 33 numbered 20-40 and the infrared lens receivers 34 numbered 70-90. The controller 5 only collects the light source information within the range and transmits it to the external computer 21 to form a monitoring three-dimensional contour map and a depth-of-field map.

[0089] S4: Start the controller 5 to set the operating states (including on, off, power supply adjustment, etc.) of the indicating warning component 4 and the control operating device switch 6 in various situations.

[0090] For example, in the normal operating state, the controller 5 starts the normal operating state indicator light of the indicator light group 41 in the indicating warning component 4. In actual production, a green indicator light is generally used to indicate the normal operating state;

[0091] In abnormal situations, that is, when there are people entering or there are foreign objects at the edge of the monitoring area, the controller 5 starts the color warning of the indicator light group 41 and the buzzer 42 to beep and controls the operating state of the control operating device switch 6. In actual production, yellow is generally used to indicate that please be careful that you have entered the monitoring area and stay away from the operating equipment to avoid danger. The buzzer 42 can generate a beeping sound for warning purposes;

[0092] When a person is relatively close to the equipment within the monitoring area, the controller 5 starts the color warning of the indicator light group 41 and the buzzer 42 to beep. In actual production, red is generally used. The bright color warns people to be careful and stay away from danger. The buzzer 42 can generate a beeping sound for warning purposes.

[0093] Preferably, the controller 5 is connected to the emergency stop switch of the operating device. When a person is close to the operating device, the controller 5 remotely controls the device to stop urgently to avoid danger.

[0094] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "top", "bottom", "inner", "outer", "rear", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0095] In the present application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

Any person skilled in the art can easily make changes or variations within the technical scope disclosed by the present invention, and such changes or variations should be covered within the protection scope of the present invention.
