Description

Technical Field

[0001] This invention relates to the field of downhole safety monitoring technology, specifically a monitoring and early warning device based on wearable devices. Background Technology

[0002] As a core pillar industry of my country's energy supply, the coal industry's production environment is characterized by confined underground spaces, complex geological conditions, high dust concentrations, and dim lighting. Various violations of safety regulations (illegal command, illegal operation, and violation of labor discipline) during operations are the main causes of production safety accidents, directly threatening the lives of frontline employees and the stable operation of enterprises. Therefore, real-time and accurate monitoring of these violations by coal mine employees is a crucial link in ensuring safe coal mine production. Currently, underground monitoring of these violations mainly relies on fixed-deployment video surveillance equipment such as cameras. This type of monitoring method has many insurmountable shortcomings in practical application, resulting in significantly reduced monitoring accuracy and failing to meet the needs of comprehensive, blind-spot-free safety supervision. On the one hand, cameras have serious blind spots: underground roadways have many branches and equipment are densely arranged. Due to the limitations of installation location and shooting angle, cameras cannot cover key areas such as roadway corners, the bottom of equipment, and the area behind the working face. These blind spots often become hidden danger zones for violations of safety regulations, which cannot be effectively captured. On the other hand, the problem of body parts being obscured is frequent: underground workers need to wear personal protective equipment such as safety helmets, dust masks, and protective face shields. At the same time, the work process often involves moving materials and operating equipment, which can easily lead to limbs, tools, etc., obscuring key body parts or work actions. This makes it impossible for cameras to clearly identify whether the worker's operating posture and work process are compliant, resulting in misjudgment or omission of violations of safety regulations. In addition, fixed camera monitoring also has the problem of poor environmental adaptability: the high dust, humidity, and strong vibration environment underground can easily cause camera lens contamination and equipment failure, further reducing the stability and reliability of monitoring. At the same time, this method is difficult to achieve full-process tracking and monitoring of mobile workers. When workers leave the monitoring range of fixed cameras, they are in a regulatory vacuum, and their violations of safety regulations cannot be detected and warned in time.

[0003] To address the inherent shortcomings of fixed monitoring equipment, wearable monitoring devices, with their unique advantages such as close-fitting wear, strong tracking ability, and good environmental adaptability, are gradually becoming an important development direction for monitoring violations in coal mines. Wearable devices can be directly worn on key parts of the employee's body (such as safety helmets, wrists, and waists), and can follow the employee's movements to cover the entire work trajectory, fundamentally eliminating the blind spots of fixed cameras. At the same time, their ability to collect employee work data at close range can effectively avoid the obstruction and interference of body parts and the external environment on the monitoring field of view, accurately capturing key information such as the employee's operating actions, body posture, and work position. In addition, wearable devices can integrate multiple sensors (such as inertial sensors, image sensors, and sound and light sensors), combined with edge computing technology to achieve real-time identification and local early warning of violations, enabling rapid response to dangerous work conditions, providing immediate reminders to on-site supervisors and employees, and significantly improving the timeliness and effectiveness of safety supervision. Based on this, developing wearable monitoring equipment for violations of safety regulations that is adapted to the complex working environment of underground coal mines is of great practical significance and application value for making up for the shortcomings of existing monitoring technologies and improving the level of safety production supervision in coal mines. Summary of the Invention

[0004] This invention provides the following technical solution: a monitoring and early warning device based on wearable devices, comprising:

[0005] Wearable carrier, which can be a headband-mounted or body-worn device;

[0006] A detection and early warning device is fixedly mounted on a wearable carrier so that it can be worn by a miner and carried underground for monitoring and early warning during underground operations. The detection and early warning device includes a monitoring unit and an underground lighting unit.

[0007] The wearable carrier also includes a wireless transmitting device, which is electrically connected to the detection and early warning device. When the detection and early warning device detects danger or illegal operation, it transmits the information to the well monitoring room via the wireless transmitting device.

[0008] As a preferred embodiment of the present invention, the monitoring unit includes a shell fixedly installed on a wearable carrier, a ring block fixedly disposed inside the shell, a dust cover fixedly disposed on the side of the ring block, a monitoring camera fixedly disposed inside the dust cover, the monitoring camera being used to capture illegal operations underground, and transmitting the captured signals to the monitoring room above ground via the wireless transmitting device, a camera opening penetrating through the middle of the dust cover, and a gap for accommodating airflow being formed between the camera opening and the monitoring camera.

[0009] As a preferred embodiment of the present invention, the outer casing is further provided with a ventilation device and an early warning device;

[0010] The ventilation device includes a fan that is movably arranged along the axial direction of the outer casing, and four guide rods fixedly installed on the side of the ring block away from the monitoring camera. The four guide rods are distributed around the circumference of the ring block. The fan slides along the inside of the outer casing through a sliding connection with the four guide rods. A spring is sleeved on the periphery of each of the four guide rods, and a nut is threaded onto the end of each of the four guide rods. The spring is fixedly installed between the fan and the nut.

[0011] As a preferred embodiment of the present invention, the early warning device includes a sheet metal ring fixedly installed inside the housing. The sheet metal ring is located at the end of the air-expelling device away from the monitoring camera. A crossbeam is fixedly installed inside the sheet metal ring. A central shaft is rotatably installed inside the crossbeam. The central shaft is coaxial with the fan. A power connection plate is fixedly installed at the end of the central shaft near the air-expelling device. Initially, the power connection plate does not contact the end of the fan blades.

[0012] As a preferred embodiment of the present invention, a sheet metal bracket is fixedly installed at the end of the central shaft away from the power connection plate. Both ends of the sheet metal bracket are bent at ninety degrees, and two springs are fixedly installed at the bent portions at both ends of the sheet metal bracket. There are two springs, and a metal ball is fixedly installed at the ends of the two springs that are away from each other. The metal ball is located on the side of the sheet metal ring.

[0013] As a preferred embodiment of the present invention, the side of the outer shell is provided with a plurality of release grooves distributed at equal angles, and an impact piece is bent and arranged inside the release groove. The impact piece is located on the rotating track of the metal ball and is perpendicular to the rotating direction of the metal ball.

[0014] As a preferred embodiment of the present invention, the downhole lighting unit includes a focusing cover fixedly installed on the outside of the dust cover, the focusing cover extending to the periphery of the end of the dust cover, an annular lamp tube fixedly installed between the focusing cover and the dust cover, and a reflector bowl for focusing light fixedly installed between the focusing cover and the dust cover, which is suitable for focusing and reflecting the bright light emitted by the annular lamp tube through the reflector bowl.

[0015] As a preferred embodiment of the present invention, a lampshade is fixedly installed between the end of the light-concentrating cover and the end of the dust cover, and the lampshade is made of high light transmittance acrylic material.

[0016] As a preferred embodiment of the present invention, a connecting piece is fixedly installed between the inner wall of the dust cover and the outer wall of the monitoring camera, the monitoring camera is fixed by the connecting piece, and multiple ventilation slots are provided through the side of the connecting piece.

[0017] As a preferred embodiment of the present invention, a sheet metal sealing plate is fixedly installed at the end of the outer casing away from the monitoring camera, and multiple air inlet slots are provided through the side of the sheet metal sealing plate.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. Air is drawn in by a fan and delivered to one end of the monitoring camera. The airflow enters the channel between the monitoring camera and the dust cover through the inside of the ring block. As the fan continues to deliver air, the airflow then exits through multiple ventilation slots from the gap between the camera port and the monitoring camera. This process removes the heat generated by the monitoring camera while the airflow blows outward through the camera port to blow dust off the camera lens. Furthermore, the continuous outward airflow from the camera port also disperses dust floating in the air near the monitoring camera, thus reducing dust adhesion to the camera and ensuring that the monitoring camera always has good visibility, thereby enabling accurate monitoring of the mine.

[0020] 2. When miners attempt to cover the camera lens, since the camera is located inside the camera aperture, covering it only covers the aperture, obstructing the airflow from the blower. The blower, pushed by the airflow, slides away from the ring block along the four guide rods. The four springs are compressed and stored, and the blower gradually approaches the power connection plate until the fan blades contact it. The fan blades then rotate the power connection plate, which in turn rotates the central shaft, sheet metal bracket, springs, and metal balls. During rotation, the metal balls strike the release groove, producing a sharp metallic knocking sound to signal the miner to stop the unauthorized covering of the camera lens. If the miner ignores this, the metallic knocking sound is easily heard by underground management personnel, allowing for timely intervention and preventing underground safety hazards caused by the unauthorized operation.

[0021] 3. During normal use, the fan output shaft will not rub against the power coupling plate when driving the fan blades to rotate. Therefore, the output shaft power of the fan will not be lost during normal use, and the fan load will not increase. This also helps to reduce the power consumption of the fan, thereby increasing the battery life of the device. The device can be powered by a built-in lithium battery inside the casing, which provides the power required for the device to operate. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figure 4 The technical solution provided by the present invention specifically includes the following embodiments:

[0033] A monitoring and early warning device based on wearable devices includes a wearable carrier 100 and a detection and early warning device 200. The wearable carrier 100 can be a headband or a bodyband. The detection and early warning device 200 is fixedly mounted on the wearable carrier 100 so that the detection and early warning device 200 can be worn by the miner underground for monitoring and early warning of underground operations. The detection and early warning device 200 includes a monitoring unit and an underground lighting unit. The wearable carrier 100 also includes a wireless transmission device 300, which is electrically connected to the detection and early warning device 200. When the detection and early warning device 200 detects dangerous or illegal operations, it can transmit the information to the surface monitoring room through the wireless transmission device 300.

[0034] For further details, please refer to [link / reference]. Figure 5 , Figure 7 , Figure 6 As shown:

[0035] The monitoring unit includes a housing 201 fixedly mounted on a wearable carrier 100. A ring block 202 is fixedly installed inside the housing 201, and a dust cover 204 is fixedly installed on the side of the ring block 202. A monitoring camera 203 is fixedly installed inside the dust cover 204. The monitoring camera 203 is used to capture images of illegal operations underground and transmits the captured signals to the surface monitoring room via a wireless transmission device 300. A camera opening 2041 is provided through the center of the dust cover 204, forming a gap between the camera opening 2041 and the monitoring camera 203 to allow airflow. The housing 201 also includes a ventilation device 208 and an early warning device 209. The ventilation device 208 includes a fan 2081 that is movably mounted along the axial direction of the housing 201. The fan 2081 slides along the inside of the outer shell 201 through a sliding connection with the four guide rods 2082 on the side of the ring block 202 away from the monitoring camera 203. The four guide rods 2082 are distributed along the circumference of the center of the ring block 202. The fan 2081 slides along the inside of the outer shell 201 through a sliding connection with the four guide rods 2082. A spring 2083 is sleeved on the periphery of each of the four guide rods 2082. A nut 2084 is threaded on the end of each of the four guide rods 2082. The spring 2083 is fixedly installed between the fan 2081 and the nut 2084. A connecting piece 206 is fixedly installed between the inner wall of the dust cover 204 and the outer wall of the monitoring camera 203. The monitoring camera 203 is fixed through the connecting piece 206. Multiple ventilation slots 207 are opened through the side of the connecting piece 206. Air is drawn in by the fan 2081 and delivered to one end of the monitoring camera 203. The airflow enters the channel between the monitoring camera 203 and the dust cover 204 through the inside of the ring block 202. As the fan 2081 continues to deliver air, the airflow is then output through multiple ventilation slots 207 from the gap between the camera port 2041 and the monitoring camera 203. This process removes the heat generated by the monitoring camera 203 during operation. At the same time, the airflow blown outward through the camera port 2041 is also used to blow dust off the lens of the monitoring camera 203. Furthermore, as the airflow is continuously output from the camera port 2041, it can also disperse and float the dust floating in the air near the monitoring camera 203 away from the monitoring camera 203, thereby alleviating the situation of dust adhering to the monitoring camera 203 and ensuring that the monitoring camera 203 always has a good perspective effect, thus enabling accurate monitoring of the underground.

[0036] For further details, please refer to [link / reference]. Figure 8 , Figure 8 As shown:

[0037] The early warning device 209 includes a sheet metal ring 2091 fixedly installed inside the housing 201. The sheet metal ring 2091 is located at the end of the exhaust fan 208 away from the monitoring camera 203. A crossbeam 2092 is fixedly installed inside the sheet metal ring 2091. A central shaft 2093 is rotatably installed inside the crossbeam 2092. The central shaft 2093 is coaxial with the fan 2081. A power connection plate 2094 is fixedly installed at the end of the central shaft 2093 near the exhaust fan 208. Initially, the power connection plate 2094 does not contact the end of the fan blades of the fan 2081. Therefore, during normal use, the output shaft of the fan 2081 will not rub against the power coupling plate 2094 when driving the fan blades to rotate. Thus, the output shaft of the fan 2081 will not lose power during normal use, and the load on the fan 2081 will not increase. This also helps to reduce the power consumption of the fan 2081, thereby increasing the battery life of the device. The device can be powered by a built-in lithium battery inside the housing 201, thus providing the electrical energy required for the device to operate.

[0038] For further details, please refer to [link / reference]. Figure 5 As shown:

[0039] A sheet metal bracket 2095 is fixedly installed at the end of the central shaft 2093 away from the power connection plate 2094. Both ends of the sheet metal bracket 2095 are bent at ninety degrees, and two springs 2096 are fixedly installed at the bent parts at both ends of the sheet metal bracket 2095. There are two springs 2096, and a metal ball 2097 is fixedly installed at the end of each spring 2096 away from the other end. The metal ball 2097 is located on the side of the sheet metal ring 2091. Multiple release grooves 2098 are distributed at equal angles on the side of the outer shell 201. Impact pieces 2099 are bent inside the release grooves 2098. The impact pieces 2099 are located on the rotating track of the metal ball 2097 and are perpendicular to the rotating direction of the metal ball 2097. When miners attempt to cover the lens of monitoring camera 203, since camera 203 is located inside the camera aperture 2041, covering camera 203 only covers the camera aperture 2041, obstructing the airflow delivered by fan 2081. The fan 2081, pushed by the airflow, slides along the four guide rods 2082 away from the ring block 202. The four springs 2083 are compressed and store energy. Fan 2081 gradually slides along the four guide rods 2082 towards the power connection plate 2094 until the tip of the fan blades of fan 2081 connects with the power connection plate 2094. Upon contact, the fan blades of the blower 2081 drive the power connection plate 2094 to rotate. The power connection plate 2094 further drives the central shaft 2093, sheet metal bracket 2095, spring 2096, and metal ball 2097 to rotate together. During the rotation, the metal ball 2097 strikes the release groove 2098 one by one, producing a sharp metallic knocking sound to indicate to the miner to stop the illegal operation of covering the lens of the monitoring camera 203. If the miner ignores it, the metallic knocking sound can be easily heard by the underground management personnel, who can then intervene on-site in a timely manner, thereby avoiding underground safety hazards caused by illegal operations.

[0040] For further details, please refer to [link / reference]. Figure 3 As shown:

[0041] The underground lighting unit includes a focusing cover 2012 fixedly installed on the outside of a dust cover 204. The focusing cover 2012 extends to the outer periphery of the end of the dust cover 204. A ring lamp tube 2013 is fixedly installed between the focusing cover 2012 and the dust cover 204. A reflector bowl 2014 for focusing light is also fixedly installed between the focusing cover 2012 and the dust cover 204, suitable for focusing and reflecting the light emitted by the ring lamp tube 2013 through the reflector bowl 2014. A lamp cover 2015, made of high-transmittance acrylic material, is fixedly installed between the end of the focusing cover 2012 and the end of the dust cover 204. After the light is emitted by the ring lamp tube 2013, the light is focused and reflected by the reflector bowl 2014 and then emitted outward through the lamp cover 2015. This provides daily lighting for underground operations and also provides the lighting required for monitoring and shooting by the monitoring camera 203, thereby improving the clarity of the shooting.

[0042] For further details, please refer to [link / reference]. ​ As shown:

[0043] A sheet metal sealing plate 2010 is fixedly installed at the end of the housing 201 away from the monitoring camera 203. Multiple air inlet slots 2011 are provided through the side of the sheet metal sealing plate 2010. The sheet metal sealing plate 2010 is used to shield the inside of the housing 201, reduce dust accumulation on the components inside the sheet metal sealing plate 2010, and the multiple air inlet slots 2011 can be used to supplement air into the housing 201, thereby supplying the air required by the fan 2081.

[0044] When a wearable device-based monitoring and early warning device is in operation, a fan 2081 draws air and delivers it to one end of the monitoring camera 203. The airflow enters the channel between the monitoring camera 203 and the dust cover 204 through the inside of the ring block 202. As the fan 2081 continues to deliver the airflow, the airflow is then output through multiple ventilation slots 207 from the gap between the camera port 2041 and the monitoring camera 203. This process removes the heat generated by the monitoring camera 203 during operation. At the same time, the airflow blowing outward through the camera port 2041 also blows dust off the lens of the monitoring camera 203. Furthermore, because the camera port 2041 continuously outputs airflow outward, it can also disperse and float dust floating in the air near the monitoring camera 203 away from the monitoring camera 203, thereby alleviating the situation of dust adhering to the monitoring camera 203 and ensuring that the monitoring camera 203 always has a good viewing effect, thus enabling accurate monitoring of the underground.

[0045] When miners attempt to cover the lens of monitoring camera 203, since camera 203 is located inside the camera aperture 2041, covering camera 203 only covers the camera aperture 2041, obstructing the airflow delivered by fan 2081. The fan 2081, pushed by the airflow, slides along the four guide rods 2082 away from the ring block 202. The four springs 2083 are compressed and store energy. Fan 2081 gradually slides along the four guide rods 2082 towards the power connection plate 2094 until the tip of the fan blades of fan 2081 connects with the power connection plate 2094. Upon contact, the fan blades of the blower 2081 drive the power connection plate 2094 to rotate. The power connection plate 2094 further drives the central shaft 2093, sheet metal bracket 2095, spring 2096, and metal ball 2097 to rotate together. During the rotation, the metal ball 2097 strikes the release groove 2098 one by one, producing a sharp metallic knocking sound to indicate to the miner to stop the illegal operation of covering the lens of the monitoring camera 203. If the miner ignores it, the metallic knocking sound can be easily heard by the underground management personnel, who can then intervene on-site in a timely manner, thereby avoiding underground safety hazards caused by illegal operations.

[0046] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention.
