The extension direction of the first-level infrared light curtain sensor is different from the extension direction of the guide rail, and the first-level infrared light curtain sensor moves on the guide rail through the adjustment seat.

[0008] Furthermore, the first-level monitoring unit also includes a locking component, which is arranged between the adjustment seat and the guide rail. The locking component has a relatively set locking state and an unlocked state. When the locking component is in the locked state, the adjustment seat and the guide rail are fixed, and when the locking component is in the unlocked state, the adjustment seat can move relative to the guide rail.

[0009] Furthermore, the primary infrared light curtain sensor is rotatably arranged on the adjustment seat, and the protective plate rotates synchronously with the primary infrared light curtain sensor.

[0010] Furthermore, the first-level monitoring unit also includes a transmission structure, which is arranged between the locking assembly and the first-level infrared light curtain sensor. The first-level infrared light curtain sensor has a relatively set initial position and a collision position. The first-level infrared light curtain sensor rotates relative to the adjustment seat to switch between the initial position and the collision position. When the first-level infrared light curtain sensor rotates, it can drive the locking assembly to switch between a locked state and an unlocked state through the transmission structure.

Each monitoring unit is provided with an infrared light curtain sensor and an alarm for monitoring any possible intrusion object. Among them, the primary monitoring unit is a vertically mounted infrared light curtain sensor, which can detect the initial entry of the intrusion object. Once the object is detected, the alarm is immediately activated, and an alarm is sounded to warn the intruder to stop. The secondary monitoring unit can determine the length of the intrusion object. When the object enters, the sensor feeds back the length of the object according to the size of the shielding area, which helps to identify whether the intruder is a person or equipment, and activates the corresponding early warning mechanism. In addition to the infrared light curtain sensor and the alarm, the tertiary monitoring unit also includes a camera module. The camera module can capture images in the mine in real time and collect video data. When the intrusion object triggers the infrared light curtain, the camera module is activated to collect images at the moment of the intrusion for subsequent analysis and recording. The control and transmission unit is the core, which is electrically connected to the units of each level of the monitoring component and is responsible for collecting data signals generated by the infrared light curtain sensor and the camera module.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] like Figures 1 to 4As shown, an embodiment of the present invention provides an underground intrusion detection and early warning device, which includes a monitoring component 01 and a control and transmission unit 02. The monitoring component 01 includes a primary monitoring unit 10, a secondary monitoring unit 20 and a tertiary monitoring unit 30 arranged in sequence along the extension direction of the mine. The primary monitoring unit 10, the secondary monitoring unit 20 and the tertiary monitoring unit 30 can all monitor intrusion objects. The primary monitoring unit 10, the secondary monitoring unit 20 and the tertiary monitoring unit 30 are all provided with an infrared light curtain sensor and an alarm 101. The secondary monitoring unit 20 can monitor the length of the intrusion object. The tertiary monitoring unit 30 also includes a camera module 31, which can collect image signals in the mine. The control and transmission unit 02 is electrically connected to the primary monitoring unit 10, the secondary monitoring unit 20 and the tertiary monitoring unit 30 respectively. The control and transmission unit 02 can collect data signals of the primary monitoring unit 10, the secondary monitoring unit 20, the first and third monitoring units 30, and send the data signals to the management platform 05.

[0040] According to the technical solution of the present invention, the monitoring component 01 is composed of three main monitoring units: a first-level monitoring unit 10, a second-level monitoring unit 20 and a third-level monitoring unit 30. These units are arranged in sequence along the extension direction of the mine. Each monitoring unit is provided with an infrared light curtain sensor and an alarm 101 for monitoring any possible intrusion objects. Among them, the first-level monitoring unit is a vertically mounted infrared light curtain sensor, which can monitor the initial entry of the intrusion object. Once the object is detected, the alarm 101 is immediately activated to sound an alarm to warn the intruder to stop. The second-level monitoring unit 20 can determine the length of the intrusion object. When the object enters, the sensor feeds back the length of the object according to the size of the shielding area, which helps to identify whether the intruder is a person or equipment, and activates the corresponding early warning mechanism. In addition to the infrared light curtain sensor and the alarm 101, the third-level monitoring unit 30 also includes a camera module 31. The camera module 31 can capture images in the mine in real time and collect video data. When the intrusion object triggers the infrared light curtain, the camera module 31 is activated to collect images at the moment of the intrusion for subsequent analysis and recording. Among them, the camera module 31 includes a video acquisition unit 311. The control and transmission unit 02 is the core, electrically connected to each level of the monitoring component 01, and is responsible for collecting data signals generated by the infrared light curtain sensor and the video acquisition unit 311. These signals include monitoring information, length data, and video images of intruding objects. The control and transmission unit 02 preliminarily processes and integrates the collected information through the industrial Ethernet ring network 03, and then receives the information through the network receiving unit 04 to the management platform 05. The device provided in this embodiment can realize the intrusion identification of intruding objects and the identification of the intruding object body, and can implement targeted early warning actions, thereby improving the reliability of underground intrusion early warning.

[0041] When an object intrudes into the primary monitoring unit 10, the infrared light curtain sensor detects the obstruction, and the local alarm 101 is immediately activated to warn the intruding object. If the object continues to move forward, the secondary monitoring unit 20 will further monitor the length of the object to help determine its type. If the object still does not stop and enters the range of the tertiary monitoring unit 30, the camera module 31 will automatically start to capture real-time images and transmit the image data together with the previously collected signals to the management platform 05. Based on the collected information, the management platform 05 analyzes the nature and location of the intruding object and takes appropriate security response measures.

[0042] like Figure 3 As shown, the primary monitoring unit 10 includes a mounting seat 11, a primary infrared light curtain sensor 12 and a protective plate 13. The mounting seat 11 is arranged on the side wall of the mine, the primary infrared light curtain sensor 12 is movably arranged on the mounting seat 11, and the primary infrared light curtain sensor 12 can move along the extension direction of the mine. The protective plate 13 is arranged on the side wall of the primary infrared light curtain sensor 12 close to the inner side of the mine.

[0043] In this embodiment, the mounting base 11 provides a stable foundation for the first-level infrared light curtain sensor 12, which is tightly connected to the side wall of the mine through a fixing. The mounting base 11 adopts a combination of a slide rail and a slider, and the slide rail is arranged along the extension direction of the mine to facilitate the movement of the first-level infrared light curtain sensor 12. The protective plate 13 is directly fixed on the side wall of the first-level infrared light curtain sensor 12, facing the inside of the mine, as a line of defense to intercept potential collisions.

[0044] Specifically, the material selection of the protection plate 13 should take into account impact resistance and corrosion resistance, such as stainless steel or high-strength plastic, to ensure long-term stable operation in the harsh environment underground.

[0045] Furthermore, the mounting seat 11 includes a guide rail 111 and an adjustment seat 112. The guide rail 111 is arranged along the extension direction of the mine, the adjustment seat 112 is movably arranged on the guide rail 111, the first-level infrared light curtain sensor 12 is arranged on the adjustment seat 112, the extension direction of the first-level infrared light curtain sensor 12 is different from the extension direction of the guide rail 111, and the first-level infrared light curtain sensor 12 moves on the guide rail 111 through the adjustment seat 112. In this embodiment, the guide rail 111 is laid along the extension direction of the mine, and can be a straight line or adjusted according to a specific curve of the mine to adapt to various underground terrains. The length of the guide rail 111 can be customized according to actual needs to ensure coverage of the entire monitoring area. The adjustment seat 112 is a movable structure, and a pulley or slider matching the guide rail 111 is arranged at the bottom thereof, so that the adjustment seat 112 can slide along the guide rail 111.

[0046] Furthermore, the first-level monitoring unit 10 also includes a locking component 14, which is arranged between the adjustment seat 112 and the guide rail 111. The locking component 14 has a relatively set locking state and an unlocked state. When the locking component 14 is in the locked state, the adjustment seat 112 and the guide rail 111 are fixedly arranged. When the locking component 14 is in the unlocked state, the adjustment seat 112 can move relative to the guide rail 111.

[0047] In this embodiment, the locking assembly 14 is located between the adjustment seat 112 and the guide rail 111, and is intended to achieve the switch between the lockable and movable states between the sensor and the guide rail 111, so as to protect the first-level infrared light curtain sensor 12 from direct damage. Under normal operating conditions, the locking assembly 14 is in a locked state, and a rigid connection is formed between the adjustment seat 112 and the guide rail 111, ensuring that the first-level infrared light curtain sensor 12 is stably fixed in its predetermined position, avoiding erroneous movement caused by vibration or other non-impact factors in the underground environment. When an external force acts on the protective plate 13 and then affects the first-level infrared light curtain sensor 12, the locking assembly 14 can sense this external force and automatically switch to an unlocked state. In the unlocked state, the connection between the adjustment seat 112 and the guide rail 111 becomes active, allowing the adjustment seat 112 to slide along the guide rail 111, thereby driving the first-level infrared light curtain sensor 12 to avoid as a whole, reducing the impact of direct impact, and protecting the safety of the first-level infrared light curtain sensor 12.

[0048] Furthermore, the first-level infrared light curtain sensor 12 is rotatably disposed on the adjustment seat 112, and the protective plate 13 rotates synchronously with the first-level infrared light curtain sensor 12. In this embodiment, the adjustment seat 112 is a sliding mechanism disposed on the guide rail 111, and the adjustment seat 112 can allow the first-level infrared light curtain sensor 12 to rotate at a certain angle, thereby allowing the sensor to rotate and dodge when subjected to external forces to avoid direct damage. The protective plate 13 is fixed to the side wall of the first-level infrared light curtain sensor 12 facing the interior of the mine, and rotates synchronously with the first-level infrared light curtain sensor 12. When the sensor is collided, the protective plate 13 rotates accordingly to form a dynamic protective barrier to block and disperse the collision force, and trigger the early warning module at the same time.

[0049] Furthermore, the first-level monitoring unit 10 also includes a transmission structure 15, which is arranged between the locking assembly 14 and the first-level infrared light curtain sensor 12. The first-level infrared light curtain sensor 12 has a relatively set initial position and a collision position. The first-level infrared light curtain sensor 12 rotates relative to the adjustment seat 112 to switch between the initial position and the collision position. When the first-level infrared light curtain sensor 12 rotates, it can drive the locking assembly 14 to switch between a locked state and an unlocked state through the transmission structure 15. When the first-level infrared light curtain sensor 12 is in the initial position, the locking assembly 14 is in a locked state. When the first-level infrared light curtain sensor 12 is in the collision position, the locking assembly 14 is in an unlocked state.

[0050] In this embodiment, the first-level infrared light curtain sensor 12 has a preset initial position, which is the position when the sensor is working normally. The first-level infrared light curtain sensor 12 also has a collision position, and when the sensor is subjected to external force, it can rotate to this position to avoid direct damage. The locking assembly 14 is intended to maintain the stability of the sensor in the initial position and prevent it from moving at will due to external forces in non-collision situations. The transmission structure 15 is arranged between the locking assembly 14 and the first-level infrared light curtain sensor 12. When the first-level infrared light curtain sensor 12 rotates due to a collision, the transmission structure 15 can transmit this movement to the locking assembly 14, triggering it to switch from a locked state to an unlocked state. This allows the first-level infrared light curtain sensor 12 to move evasively along the slide rail to protect itself.

[0051] Furthermore, the locking assembly 14 includes a plug-in connector 141 and a socket 142, wherein the socket 142 is disposed on the first end of the guide rail 111, and the plug-in connector 141 is movably disposed on the adjustment seat 112, and the plug-in connector 141 cooperates with the socket 142 to lock the position of the adjustment seat 112 on the guide rail 111. In this embodiment, the plug-in connector 141 is movably disposed on the adjustment seat 112, and one end of the plug-in connector 141 is designed to be conical or wedge-shaped, so as to facilitate quick and accurate alignment and plugging with the socket 142 on the guide rail 111, and the other end is connected to the adjustment seat 112, and is fixed by threads or buckles to ensure firmness in the locked state. The socket 142 is prefabricated at the first end of the guide rail 111, and is usually distributed at equal intervals along the guide rail 111 to provide multiple locking positions. The depth and diameter of the socket 142 are designed to match the plug-in connector 141 to ensure tightness and stability during plugging. When the primary infrared light curtain sensor 12 is hit, the unlocking connector 141 enables it to move along the adjustment seat 112. The tight fit between the connector 141 and the socket 142 ensures that the position of the sensor is fixed during the monitoring process, avoiding monitoring errors caused by vibration or external forces.

[0052] like Figure 4As shown, the transmission structure 15 includes a gear 151 and a toothed structure 152. The gear 151 is coaxially arranged with the primary infrared light curtain sensor 12 and rotates synchronously with the primary infrared light curtain sensor 12. The toothed structure 152 is arranged on the connector 141. The toothed structure 152 extends along the extension direction of the connector 141. The gear 151 and the toothed structure 152 are meshed with each other. When the primary infrared light curtain sensor 12 rotates, the gear 151 and the toothed structure 152 can cooperate to drive the connector 141 to move relative to the socket 142.

[0053] In this embodiment, the gear 151 is coaxially arranged with the primary infrared light curtain sensor 12 to ensure that the two rotate synchronously. The number of teeth and the tooth shape of the gear 151 are precisely designed according to the expected rotation range and transmission efficiency to achieve stable and accurate transmission. The tooth structure 152 is installed on the connector 141, extending along the extension direction of the connector 141, matching the tooth shape of the gear 151, and forming a gear 151 rack transmission mechanism. The extension length of the tooth structure 152 should be sufficient to cover all the avoidance movement ranges of the sensor to ensure that the connector 141 can move smoothly in its direction when the sensor rotates.

[0054] Specifically, when the primary infrared light curtain sensor 12 is hit and rotates, it drives the gear 151 to rotate. Due to the meshing between the gear 151 and the toothed structure 152, each rotation of the gear 151 directly drives the toothed structure 152 to move along its axial direction, so that the connector 141 is disengaged from the socket 142, thereby allowing the primary infrared light curtain sensor 12 to slide along the guide rail 111 or the slide rail as a whole, achieving an avoidance action and reducing or avoiding damage.

[0055] Furthermore, the primary monitoring unit 10 further includes a first reset member and a second reset member. The first reset member is disposed between the adjustment seat 112 and the primary infrared light curtain sensor 12, and the first reset member is used to drive the primary infrared light curtain sensor 12 to rotate to an initial position. The second reset member is disposed between the guide rail 111 and the adjustment seat 112, and the second reset member is used to drive the adjustment seat 112 to move to the first end of the guide rail 111.

[0056] In this embodiment, the first reset member can be a spring or other elastic reset device, which is used to drive the reset of the rotation angle of the first-level infrared light curtain sensor 12, and is installed between the adjustment seat 112 and the first-level infrared light curtain sensor 12 to form a stable elastic connection to ensure that the sensor can automatically rotate back to the initial position after the rotation caused by the collision event. The second reset member is used to drive the adjustment seat 112 to reset to one end of the guide rail 111, and is located between the end of the guide rail 111 and the adjustment seat 112. In the unlocked state, the second reset member remains in a stretched or compressed state. Once the adjustment seat 112 moves along the guide rail 111, the reset member is further stretched or compressed with the displacement of the adjustment seat 112 to store the energy required for reset.

[0057] Furthermore, the monitoring component 01 also includes a fourth-level monitoring unit 40, which is located downstream of the third-level monitoring unit 30. The fourth-level monitoring unit 40 is electrically connected to the control and transmission unit 02. The fourth-level monitoring unit 40 also includes a lighting component 41, which can illuminate the mine.

[0058] In this embodiment, the fourth-level monitoring unit 40 is located downstream of the third-level monitoring unit 30. This arrangement can ensure that when the multi-level monitoring unit fails to successfully prevent the intrusion, the fourth-level monitoring unit 40 can serve as the last line of defense to provide additional early warning and lighting support. Among them, the fourth-level monitoring unit 40 includes a lighting component 41 and a control and transmission unit 02 that is tightly integrated therewith. The lighting component 41 is mainly responsible for providing high-brightness lighting to enhance visibility in the monitoring area and serve as a warning. Among them, the lighting component 41 includes a warning light tube 411 and a light tube slide 412, and the warning light tube 411 can move back and forth along the light tube slide 412.

[0059] Specifically, the warning light tube 411 can automatically adjust the brightness according to the alarm level of the monitoring unit. For example, when the first-level monitoring unit 10 detects an intrusion, the warning light tube 411 starts the basic lighting mode; after the second-level monitoring unit 20 is triggered, the brightness is increased to the warning level; and when the third-level monitoring unit 30 or a unit further downstream detects an intrusion, the warning light tube 411 reaches the maximum brightness, using strong light to warn the intruder and assist the camera module 31 to clearly capture the characteristics of the intruding object. The control and transmission unit 02 is closely integrated with the warning light tube 411. Based on the height of the intruding object identified by the first-level infrared light curtain and the second-level infrared light curtain sensor, the control and transmission unit 02 controls the warning light tube 411 to move along the light tube slide 412 to the corresponding height. For example, if the intruding object is detected to be an operator, the warning light tube 411 will move to the height corresponding to the operator's head for warning; if the intruding object is detected to be a vehicle, the warning light tube 411 will move to the height corresponding to the cab for warning. At the same time, the control and transmission unit 02 can also monitor the operating status of the warning lamp 411, such as lamp source failure, brightness adjustment error, etc., and feed back this information to the management platform 05 in a timely manner for remote maintenance or adjustment.
