Description

Technical Field

[0001] This invention relates to the field of tunnel construction technology, and in particular to a health monitoring device and intelligent scheduling method for tunnel workers. Background Technology

[0002] The invention relates to the field of tunnel engineering safety monitoring technology, and in particular to a health monitoring device and intelligent scheduling method for tunnel workers. As an important part of underground engineering, tunnel operations have significant characteristics such as enclosed space, poor air circulation, easy accumulation of harmful gases, and difficulty in temperature regulation. At the same time, there are potential risks such as changes in the stability of the surrounding rock and mechanical vibration interference during the operation, which pose a serious threat to the health and safety of the workers.

[0003] Currently, safety management at tunnel operation sites largely relies on traditional monitoring and manual dispatching methods, which have many technical shortcomings:

[0004] Firstly, environmental monitoring methods are limited. Existing equipment can only monitor a single indicator independently, and the monitoring data is disconnected from human health data. This often results in situations where environmental anomalies have occurred but are not promptly warned, or where potential health risks to personnel are not linked to environmental triggers, leading to a lag in risk identification.

[0005] Secondly, the ventilation system is inefficient. Traditional tunnel ventilation equipment mostly operates at a fixed speed and cannot dynamically adjust the ventilation intensity according to the concentration of harmful gases and dust content. Moreover, the filter structure at the ventilation holes is easily blocked by dust accumulation, requiring regular manual cleaning. This not only increases the operation and maintenance costs, but may also lead to ventilation failure due to untimely cleaning, exacerbating environmental degradation.

[0006] Third, the emergency response is slow. When workers experience emergencies such as hypoxia or health abnormalities, the delivery of rescue supplies often relies on manual handling. Due to the limitations of tunnel space and inaccurate personnel positioning, the delivery time of supplies is long, missing the best rescue opportunity. At the same time, during manual dispatch, information needs to be transmitted through walkie-talkies, which can easily lead to instruction deviations and information gaps, further reducing the efficiency of emergency response.

[0007] Fourth, personnel health monitoring lacks continuity. Existing health monitoring is mostly achieved through pre-job physical examinations or fixed-point spot checks during operations. It is impossible to collect key physiological indicators such as heart rate and blood oxygen in real time, making it difficult to detect health abnormalities caused by hypoxia, fatigue, etc. in the first instance, thus creating safety loopholes.

[0008] To address the above problems, this invention proposes a health monitoring device and intelligent scheduling method for tunnel workers. Summary of the Invention

[0009] To address the problems of inefficient emergency dispatching and slow rescue response in existing tunnel systems, this invention proposes a health monitoring device and intelligent dispatching method for tunnel workers.

[0010] This invention proposes a health monitoring device and intelligent scheduling method for tunnel workers, comprising a smoke exhaust duct. An exhaust mechanism is arrayed on the outer surface of the lower support pipe of the smoke exhaust duct. An electric slide rail is fixedly connected to the upper outer surface of the smoke exhaust duct network. A conductive rail is provided on one side of the electric slide rail. The upper end of the conductive rail is fixedly connected to the upper outer surface of the smoke exhaust duct. A connecting frame is fixedly connected to the side of the slider of the electric slide rail. A conductive block is provided at one end of the connecting frame. One end of the conductive block of the connecting frame is electrically slidably connected to the conductive groove of the conductive rail. A conveying mechanism is provided at the lower end of the slider.

[0011] Preferably, the exhaust mechanism includes a mounting block, one side of which is fixedly connected to the outer surface of the exhaust duct. A ventilation hole is provided on the inclined surface of the mounting block, the inner wall of which is fixedly connected to the inner wall of the exhaust duct. An exhaust fan is installed inside the ventilation hole, and an exhaust motor is installed on one side of the exhaust fan. The outer casing of the exhaust motor is fixedly connected to the inner wall of the ventilation hole via a fixing rod. A filter plate is fixedly connected to the inner wall of the ventilation hole, a bearing is embedded in the center of the filter plate, and a feeding rod is fixedly connected to the inner ring of the bearing. The output shaft of the exhaust motor is fixedly connected to the center of the exhaust fan via a coupling. The center of the other side of the exhaust fan is fixedly connected to the inner ring of the bearing. A gas sensor and a temperature sensor are installed at the upper end of the mounting block.

[0012] Preferably, the conveying mechanism includes a drive motor, and a mounting bracket is fixedly attached to the outer surface of the drive motor housing. The upper end of the mounting bracket is slidably engaged with the inner wall of the groove opened at the lower end of the electric slide rail. A connecting column is fixedly connected to the side of the mounting bracket, and one end of the connecting column is fixedly connected to the side of the slider.

[0013] Preferably, the lower end of the slider is symmetrically provided with hanging rings, and the inner walls of the two hanging rings are rotatably connected to winding rollers through bearings. The surface of the winding rollers is wound with steel wire rope, one end of the winding rollers is fixedly connected to a driven gear, and a transmission rod is provided between the two winding rollers. One end of the transmission rod is fixedly connected to a main gear, and the surface of the main gear meshes with the surfaces of the two driven gears respectively. The outer surface of the transmission rod is rotatably sleeved with a fixing ring through a bearing, and the surface of the fixing ring is fixedly connected to the lower surface of the slider.

[0014] Preferably, L-shaped limiting plates are symmetrically arranged on both sides of the slider, and mounting grooves are symmetrically opened on both sides of the slider. A fixed pulley is fixedly connected to the inner wall of the mounting groove. One end of the wire rope enters along the lower surface of the slider and passes through the inner wall of the mounting groove of the slider. The surface of the wire rope is slidably connected to the surface of the fixed pulley and the surface of the wire rope is slidably connected to the body of the slider. One end of the wire rope passes through the limiting plate and extends to the bottom of the limiting plate.

[0015] Preferably, the surface of the wire rope is slidably connected with fixed plates, and two adjacent fixed plates are fixedly connected by steel reinforcing ribs. The end of the wire rope is fixedly connected to the end face of the fixed plate located at the bottom of the array. Each fixed plate is provided with an array of elastic limiting clips on its surface, and the surface of the elastic limiting clips holds a portable oxygen cylinder.

[0016] Preferably, one end of the exhaust motor is electrically connected to the conductive groove of the conductive rail via a cable, and one end of the drive motor is electrically connected to the conductive block of the connecting rod via a cable.

[0017] Preferably, a controller is provided on the side of the slider. The controller includes a data processing module, a wireless communication module, a drive control module, and an alarm control module. The data processing module is used to receive data from the gas sensor and the temperature sensor and perform analysis and comparison. The wireless communication module is used to establish two-way communication with the terminal equipment of the tunnel management center. The drive control module is used to send start, stop, and adjustment commands to the exhaust motor, the drive motor, and other power sources. The alarm control module is used to trigger an externally installed audible and visual alarm device.

[0018] Preferably, the gas sensor and the temperature sensor are electrically connected to the conductive groove of the conductive rail via cables, and are communicatively connected to the controller on the side of the slider.

[0019] Preferably, the intelligent scheduling method for the health monitoring equipment of tunnel workers is as follows:

[0020] Step 1: Before entering the tunnel, each worker wears a health monitoring ring on their arm. This ring monitors the worker's health status and transmits the data in real time to the controller on the side of the slider via a built-in wireless communication module. The controller then transmits the data to an external terminal device. If the gas sensor and temperature sensor on the upper part of the mounting block, as well as the monitoring ring worn by the worker, trigger an alarm signal, the monitoring ring will simultaneously send its position in the tunnel to the external terminal via a built-in positioning module. Then, the controller will issue instructions to the ventilation and conveying mechanisms.

[0021] Step 2: The slider on the electric slide rail drives the conveying mechanism to the abnormal position. The exhaust mechanism responds and executes synchronously with the conveying mechanism. The controller starts the exhaust motor through the drive control module. Based on the concentration of harmful gases detected by the gas sensor and the ambient temperature data from the temperature sensor, the exhaust fan speed is adjusted. The more serious the concentration or temperature exceeds the standard, the higher the speed. At the same time, the exhaust fan rotation drives the material-pulling rod to rotate, cleaning the dust and impurities attached to the surface of the filter plate, ensuring that the ventilation holes are unobstructed, and the harmful gases in the tunnel are discharged through the smoke exhaust pipe.

[0022] Step 3: Start the drive motor synchronously, which drives the main gear fixed at the end of the transmission rod to rotate. The main gear meshes and drives the driven gears and winding rollers on both sides to rotate, releasing the wire rope. The coiled array fixing plates gradually form a vertical array under the action of the wire rope. The wire rope drives the array fixing plates and the portable oxygen cylinder held by the elastic limit clamp to be smoothly transported to a height that the operator can reach. The operator takes out the portable oxygen cylinder to ensure their survival environment.

[0023] The beneficial effects of this invention are as follows:

[0024] 1. By installing gas and temperature sensors on the upper part of the mounting block, as well as health monitoring rings worn by workers, synchronous collection of tunnel environmental data and personnel physiological data is achieved. The controller data processing module analyzes and compares the data in real time, providing early warnings of risks such as excessive levels of harmful gases, abnormal temperatures, or abnormal heart rate and blood oxygen levels, thus preventing safety accidents caused by environmental deterioration or undetected health hazards and building a double safety barrier for tunnel operations.

[0025] 2. By setting up an exhaust mechanism and a conveying mechanism, the exhaust fan motor dynamically adjusts the exhaust fan speed according to environmental data, and works with the material guide rod to automatically clean the dust from the filter plate to ensure smooth ventilation; at the same time, the electric slide rail drives the conveying mechanism to move precisely to the abnormal position, and releases the steel wire rope through gear transmission to quickly transport the portable oxygen cylinder, greatly shortening the emergency response time.

[0026] 3. By setting up a wireless communication module for two-way linkage with the tunnel management center, automatic data uploading and remote command issuance are achieved. The entire dispatching process does not require manual on-site operation. A closed loop is formed from abnormal warning, equipment startup, resource delivery to status feedback, which reduces the error of manual monitoring and dispatching and also reduces the workload of management personnel. At the same time, the array-type fixing plate and elastic limit clamp can carry oxygen cylinders in batches to meet the emergency needs of multiple people, improving the practicality and dispatching flexibility of the equipment.

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0039] Reference Figures 1-10A health monitoring device for tunnel workers includes a smoke exhaust duct 1. A ventilation mechanism 2 is arrayed on the outer surface of a support pipe at the lower end of the smoke exhaust duct 1. An electric slide rail 4 is fixedly connected to the outer surface of the upper end of the smoke exhaust duct 1. A conductive rail 3 is provided on one side of the electric slide rail 4. The upper end of the conductive rail 3 is fixedly connected to the outer surface of the upper end of the smoke exhaust duct 1. A connecting frame 6 is fixedly connected to the side of a slider 40 of the electric slide rail 4. A conductive block is provided at one end of the connecting frame 6. One end of the conductive block of the connecting frame 6 is electrically slidably connected to the conductive groove of the conductive rail 3. A conveying mechanism 5 is provided at the lower end of the slider 40.

[0040] In this embodiment, the exhaust mechanism 2 includes a mounting block 21. One side of the mounting block 21 is fixedly connected to the outer surface of the exhaust duct 1. A ventilation hole is provided on the inclined surface of the mounting block 21. The inner wall of the ventilation hole is fixedly connected to the inner wall of the exhaust duct 1. An exhaust fan 22 is provided inside the ventilation hole. An exhaust motor 23 is provided on one side of the exhaust fan 22. The outer housing of the exhaust motor 23 is fixedly connected to the inner wall of the ventilation hole through a fixing rod. A filter plate 24 is fixedly connected to the inner wall of the ventilation hole. A bearing is embedded in the center of the filter plate 24. A feed rod 25 is fixedly connected to the inner ring of the bearing. The output shaft of the exhaust motor 23 is fixedly connected to the center of the exhaust fan 22 through a coupling. The center of the other side of the exhaust fan 22 is fixedly connected to the inner ring of the bearing. A gas sensor and a temperature sensor are provided at the upper end of the mounting block 21.

[0041] Specifically, the filter plate 24 is made of metal mesh with a pore size of 0.5-1mm, which can block dust in the tunnel from entering the smoke exhaust pipe 1. The length of the material-pushing rod 25 is adapted to the radius of the filter plate 24. When the exhaust fan 22 rotates, it drives the material-pushing rod 25 to rotate synchronously, scraping off the dust attached to the surface of the filter plate 24 to achieve a self-cleaning function. The gas sensor adopts an electrochemical sensor, which can detect the concentration of various harmful gases such as carbon monoxide and methane. The temperature sensor has a detection range of -10℃ to 60℃. The detection data of both are transmitted to the controller in real time via cable.

[0042] In this embodiment, the conveying mechanism 5 includes a drive motor 51, and a mounting bracket 52 is fixedly attached to the outer surface of the housing of the drive motor 51. The upper end of the mounting bracket 52 is slidably engaged with the inner wall of the groove opened at the lower end of the electric slide rail 4. A connecting post 53 is fixedly connected to the side of the mounting bracket 52, and one end of the connecting post 53 is fixedly connected to the side of the slider 40.

[0043] Specifically, the mounting bracket 52 adopts a U-shaped structure, and its upper end has a sliding snap-fit ​​method that is compatible with the slide groove of the electric slide rail 4. It can move synchronously with the slider 40 to ensure the stability of the drive motor 51 when it moves. The connecting column 53 is fixed to the mounting bracket 52 and the slider 40 by bolts, providing a fixing function for the mounting bracket 52. The drive motor 51 adopts a stepper motor, which can precisely control the speed and adapt to the winding and unwinding speed requirements of the wire rope 56.

[0044] In this embodiment, the lower end of the slider 40 is symmetrically provided with hanging rings 54. The inner walls of the two hanging rings 54 are rotatably connected to winding rollers 55 through bearings. The surface of the winding rollers 55 is wound with steel wire rope 56. One end of the winding rollers 55 is fixedly connected to the driven gear 57. A transmission rod 58 is provided between the two winding rollers 55. One end of the transmission rod 58 is fixedly connected to the main gear 59. The surface of the main gear 59 meshes with the surfaces of the two driven gears 57 respectively. The outer surface of the transmission rod 58 is rotatably sleeved with a fixing ring 510 through bearings. The surface of the fixing ring 510 is fixedly connected to the lower surface of the slider 40.

[0045] Specifically, the hanging ring 54 and the slider 40 are integrally formed. The outer ring of the bearing is interference-fitted with the inner wall of the hanging ring 54, and the inner ring is fixed to both ends of the winding roller 55 to reduce the frictional resistance when the winding roller 55 rotates. The main gear 59 and the driven gear 57 have the same module. When meshing, they can drive the two winding rollers 55 to rotate synchronously, ensuring that the winding and unwinding speeds of the wire ropes 56 on both sides are the same. The fixing ring 510 is fixed to the slider 40 by welding, which plays a supporting and limiting role for the transmission rod 58 and prevents deviation during transmission.

[0046] In this embodiment, L-shaped limiting plates 511 are symmetrically arranged on both sides of the slider 40, and mounting grooves are symmetrically opened on both sides of the slider 40. A fixed pulley is fixedly connected to the inner wall of the mounting groove. One end of the wire rope 56 enters along the lower surface of the slider 40 and passes through the inner wall of the mounting groove of the slider 40. The surface of the wire rope 56 is slidably connected to the surface of the fixed pulley and the surface of the wire rope 56 is slidably connected to the body of the slider 40. One end of the wire rope 56 passes through the limiting plate 511 and extends to the bottom of the limiting plate 511.

[0047] Specifically, the L-shaped limiting plate 511 is fixed to the slider 40 by bolts, and the through hole at its lower end is adapted to the diameter of the wire rope 56, which can limit the swing range of the wire rope 56; the shaft of the fixed pulley is fixed to the inner wall of the mounting groove, so that the winding and unwinding force of the winding roller 55 is transmitted to the fixed plate 512 more smoothly.

[0048] In this embodiment, the surface of the wire rope 56 is slidably connected to the fixing plate 512. Two adjacent fixing plates 512 are fixedly connected by steel reinforcing ribs. The end of the wire rope 56 is fixedly connected to the end face of the fixing plate 512 located at the bottom of the array. Each fixing plate 512 is provided with an array of elastic limiting clips 513 on its surface. The surface of the elastic limiting clips 513 holds a portable oxygen cylinder 514.

[0049] Specifically, the fixing plate 512 is made of lightweight alloy material, and its surface has sliding holes that are compatible with the wire rope 56, allowing it to slide up and down within a small range along the wire rope 56; the two ends of the reinforcing rib are fixed to the adjacent fixing plate 512 by welding to form a stable array structure; the elastic limiting clip 513 is made of rubber and has deformable characteristics. Its clamping diameter is compatible with the diameter of the portable oxygen cylinder 514, which can not only firmly fix the oxygen cylinder, but also prevent wear on the cylinder body. 3-6 elastic limiting clips 513 are evenly arranged on each fixing plate 512 to achieve batch carrying. The portable oxygen cylinder 514 can be any oxygen cylinder commonly available on the market.

[0050] In this embodiment, one end of the exhaust motor 23 is electrically connected to the conductive groove of the conductive rail 3 via a cable, and one end of the drive motor 51 is electrically connected to the conductive block of the connecting frame 6 via a cable.

[0051] Specifically, the cable is a wear-resistant and corrosion-resistant flexible cable with a flame-retardant sheath. The conductive groove of the conductive rail 3 is equipped with copper conductive sheets, and the conductive block of the connecting frame 6 is made of graphite. When the two slide in contact, they can stably transmit power, ensuring that the power supply to the exhaust motor 23, drive motor 51 and other electrical equipment is uninterrupted during the movement of the slider 40.

[0052] In this embodiment, a controller is provided on the side of the slider 40. The controller includes a data processing module, a wireless communication module, a drive control module, and an alarm control module. The data processing module is used to receive gas and temperature sensors and perform analysis and comparison. The wireless communication module is used to establish two-way communication with the terminal equipment of the tunnel management center. The drive control module is used to send start, stop, and adjustment commands to the exhaust motor 23, drive motor 51, and other power sources. The alarm control module is used to trigger externally installed audible and visual alarm devices.

[0053] Specifically, the controller adopts an integrated cabinet structure, which is bolted to the side of the slider 40 facing the tunnel working area. The outer shell of the cabinet is made of 304 stainless steel with a thickness of 2mm and the surface is powder-coated for corrosion protection. The protection level reaches IP65, which can resist the corrosion of dust, humid air and construction splashes in the tunnel, and ensure that the internal modules work stably in a temperature range of -20℃ to 70℃. Waterproof wiring holes are opened on the side of the cabinet for connecting the cables of various sensors, motors and alarm devices. The inside is equipped with independent heat sinks and dust filters, and heat dissipation is achieved through natural convection to avoid overheating of the modules during long-term operation.

[0054] The controller is powered by conductive rail 3. The internal voltage regulator module converts the input AC220V voltage to DC24V to power the various functional modules and external related devices. It is also equipped with a 1200mAh backup lithium battery, which can keep the core module of the controller working for no less than 30 minutes in the event of a sudden power outage, ensuring that data is not lost and emergency commands are transmitted.

[0055] The data processing module collects abnormal environmental information in real time, including gas and temperature values, compares them with preset data thresholds, and packages the comparison results and the original collected data. Then, it transmits the data to the external terminal device via the wireless transmission module. The external terminal device performs secondary processing on the transmitted data and issues a scheduling command to drive the module to control the conveying mechanism 5 to work quickly and lower the portable oxygen cylinder 514 to a height that the operator can reach. At the same time, the alarm control module sends an alarm signal to the external terminal.

[0056] In this embodiment, the gas sensor and temperature sensor are electrically connected to the conductive groove of the conductive rail 3 via cables, and are communicatively connected to the controller on the side of the slider 40.

[0057] Specifically, the power supply cables and signal cables of the gas sensor and temperature sensor are integrated and arranged along the exhaust duct 1 and conductive rail 3 by fixing clips to avoid cable clutter; the sensor and controller use the Modbus communication protocol to ensure the accuracy and real-time performance of detection data transmission, with a transmission delay of no more than 1 second.

[0058] Reference Figures 1-10 A smart scheduling method for health monitoring equipment for tunnel workers, the specific scheduling method is as follows:

[0059] Step 1: Before entering the tunnel, each worker wears a health monitoring ring on their arm. This ring is used to monitor the worker's health status and transmits the data in real time to the controller on the side of the slider 40 via the built-in wireless communication module. The controller then transmits the data to the external terminal device. If the gas sensor and temperature sensor on the upper end of the mounting block 21 and the monitoring ring worn by the worker trigger an alarm signal, the monitoring ring will send its position in the tunnel to the external terminal via the built-in positioning module. Then the controller will issue instructions to the ventilation mechanism 2 and the conveying mechanism 5.

[0060] Step 2: The slider 40 on the electric slide rail 4 drives the conveying mechanism 5 to the abnormal position. The exhaust mechanism 2 responds and executes synchronously with the conveying mechanism 5. The controller starts the exhaust motor 23 through the drive control module. According to the concentration of harmful gas detected by the gas sensor and the ambient temperature data of the temperature sensor, the speed of the exhaust fan 22 is adjusted. The more serious the concentration or temperature exceeds the standard, the higher the speed. At the same time, the rotation of the exhaust fan 22 drives the material feeding rod 25 to rotate, cleaning the dust and impurities attached to the surface of the filter plate 24, ensuring that the ventilation holes are unobstructed, and the harmful gas in the tunnel is discharged through the smoke exhaust pipe 1.

[0061] Step 3: Start the drive motor 51 synchronously, which drives the main gear 59 fixed at the end of the transmission rod 58 to rotate. The main gear 59 meshes and drives the driven gears 57 on both sides and the winding roller 55 to rotate, releasing the wire rope 56. The coiled array fixing plate 512 gradually forms a vertical array under the action of the wire rope 56. The wire rope 56 drives the array fixing plate 512 and the portable oxygen cylinder 514 held by the elastic limit clamp 513 to be smoothly transported to a height accessible to the operator. The operator takes out the portable oxygen cylinder 514 to ensure their survival environment.

A health monitoring device for tunnel workers according to claim 8, characterized in that: The gas sensor and the temperature sensor are electrically connected to the conductive groove of the conductive rail (3) via cables and are communicatively connected to the controller on the side of the slider (40).

10. The intelligent scheduling method for health monitoring equipment for tunnel workers according to claim 9, characterized in that, The specific scheduling method is as follows: Step 1: Before entering the tunnel, each worker wears a health monitoring ring on their arm. The monitoring ring is used to monitor the health status of the workers. The data is transmitted in real time to the controller on the side of the slider (40) through the built-in wireless communication module. The controller then transmits the data to the external terminal device. If the gas sensor and temperature sensor on the upper end of the mounting block (21) and the monitoring ring worn by the worker trigger an alarm signal, the monitoring ring will send its position in the tunnel to the external terminal through the built-in positioning module. Then the controller issues instructions to the ventilation mechanism (2) and the conveying mechanism (5). Step 2: The slider (40) on the electric slide rail (4) drives the conveying mechanism (5) to the abnormal position. The exhaust mechanism (2) and the conveying mechanism (5) respond and execute synchronously. The controller starts the exhaust motor (23) through the drive control module. According to the concentration of harmful gas detected by the gas sensor and the ambient temperature data of the temperature sensor, the speed of the exhaust fan (22) is adjusted. The more serious the concentration or temperature exceeds the standard, the higher the speed. At the same time, the exhaust fan (22) rotates and drives the material pusher (25) to rotate, cleaning the dust and impurities attached to the surface of the filter plate (24) to ensure that the ventilation hole is unobstructed. The harmful gas in the tunnel is discharged through the smoke exhaust pipe (1). Step 3: Start the drive motor (51) synchronously, drive the main gear (59) fixed at the end of the transmission rod (58) to rotate. The main gear (59) meshes and drives the side slave gears (57) and winding rollers (55) to rotate, releasing the wire rope (56). The coiled array fixing plate (512) gradually forms a vertical array under the action of the wire rope (56). The wire rope (56) drives the array fixing plate (512) and the portable oxygen cylinder (514) held by the elastic limit clamp (513) to be smoothly transported to a height accessible to the operator. The operator takes out the portable oxygen cylinder (514) to ensure its survival environment.
