Description

Technical Field

[0001] This invention relates to the field of smelting technology in the iron and steel industry, and in particular to an intelligent flexible coke oven platform safety guardrail and its manufacturing method. Background Technology

[0002] Coke ovens are core equipment in the steel industry used for coke production during the smelting process. The oven platform, as a critical area for coke oven operation, maintenance, and material transfer, is constantly exposed to a complex environment characterized by high temperatures, high dust levels, and frequent equipment movement. A certain gap exists between the edge of the oven platform and the coke car tracks, and the coke cars (including pushers and quenchers) need to move back and forth along the tracks to complete operations such as coal charging and coke pushing. This exposes the oven platform area to multiple safety risks: operators may fall due to negligence when approaching the edge; collisions may occur between coke cars and fixed structures due to relative movement; and the temporary work area during oven door maintenance lacks effective protection, easily leading to accidents. Therefore, the safety guardrails on the coke oven platform are crucial facilities for ensuring the safety of operators and regulating equipment operating boundaries; their performance directly affects the safety and continuity of coking production.

[0003] The existing protective measures for coke oven platforms are clearly inadequate: Firstly, fixed rigid guardrails are mostly used. Although they can provide basic protection, they cannot meet the needs of coke car movement. When coke cars pass, they need to be manually disassembled or overturned, which not only increases the operational burden but also poses a safety hazard of interruption of protection. Secondly, the protective structure lacks flexible adjustment capabilities, and the wire rope is prone to slack or excessive tension due to long-term tension, leading to protective failure or breakage. Third, the safety early warning mechanism is imperfect, relying solely on manual patrols, making it difficult to detect people approaching dangerous areas in a timely manner, resulting in a delayed accident response; Fourth, the support structure is fixed and cannot be flexibly adjusted according to the furnace operation scenario (such as simultaneous maintenance of multiple furnace doors), resulting in poor adaptability.

[0004] In addition, the existing protective devices are not sufficiently linked with the coke car, and friction or jamming can easily occur due to relative movement, affecting the operating efficiency of the coke car. Furthermore, the lack of unified debugging standards leads to unstable overall protection effects, making it difficult to meet the high-efficiency and safety requirements of modern coking production. Summary of the Invention

[0005] This invention provides an intelligent flexible coke oven platform safety guardrail and its manufacturing method, which realizes independent, efficient and safe operation of oven door maintenance and smoke elimination, ensures that the problem of smoke from the oven door can be dealt with in a timely manner, avoids the spread of pollutants, improves the work rhythm, and meets the needs of simultaneous operation of multiple oven doors, thus protecting the health of operators and the safety of the working environment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A smart flexible coke oven platform safety guardrail and its manufacturing method are disclosed, comprising a follow-up pulley assembly, a movable support wheel group, a wire rope assembly, a drive pulley assembly, a wire rope fixing seat, an adjusting spring assembly, and an intelligent alarm system. The follower pulley assembly is fixed to the wire rope fixing seat by connecting bolts. The movable support wheel group is arranged at intervals on the side of the furnace platform steel structure frame between the two wire rope fixing seats to support the wire rope assembly. The wire rope assembly shuttles and winds between the follower pulley assembly and the drive pulley assembly, and passes through the effective space on the side of the coke car and the furnace platform. The drive pulley assembly is fixed to the steel structure frame of the coke car by connecting bolts. The wire rope fixing seat is fixed to the furnace platform by anchor bolts. The adjusting spring assembly is located at both ends of the wire rope assembly and fixed to the corresponding position of the wire rope fixing seat. The intelligent alarm system is set on both sides of the coke car near the edge of the furnace platform.

[0007] Preferably, the follower pulley assembly includes a first pulley, a first pulley bracket, a first drive shaft, a bearing, an oil cup, a cap, a bearing seat, a set screw, and a key. The first pulley is mounted on the first pulley bracket via the first drive shaft. The first drive shaft and the first pulley bracket are connected by a bearing. A cap and a bearing seat are respectively provided on both sides of the bearing. The oil cup is disposed on the bearing seat. The set screw and key are used to fix the first drive shaft and the first pulley.

[0008] Preferably, the movable support wheel assembly includes support wheels, support columns, slewing bearings, slewing motors, pin one, swing frame, pin two, electro-hydraulic actuators, and electro-hydraulic actuator supports. The support wheels are evenly arranged in three groups on the support column with a spacing of 400 mm. The support column is connected to the swing frame via the slewing bearing. The slewing motor drives the slewing bearing to rotate. The swing frame is connected to the side of the furnace platform steel structure frame via pin one. One end of the electro-hydraulic actuator is connected to the swing frame via pin two, and the other end of the electro-hydraulic actuator is mounted on the electro-hydraulic actuator support. Pin one and the electro-hydraulic actuator support are welded to the side of the furnace platform steel structure frame.

[0009] Preferably, the wire rope assembly includes a wire rope and a wire rope clamp, and the wire rope clamp is used to fix the connection part of the wire rope. The wire rope passes between the follower pulley assembly and the drive pulley assembly to form a protective structure.

[0010] Preferably, the drive pulley assembly includes a second pulley, a second pulley bracket, a second drive shaft, a drive motor, a cover, a bearing, an oil cup, a cap, a bearing seat, a set screw, and a key. The second pulley is mounted on the second pulley bracket via the second drive shaft, and the drive motor is connected to the second drive shaft and drives it to rotate. The second drive shaft and the second pulley bracket are connected by a bearing, and a cover and a cap are respectively provided on both sides of the bearing. The oil cup is disposed on the bearing seat, and the set screw and key are used to fix the second drive shaft and the second pulley.

[0011] Preferably, the wire rope fixing seat is a welded structural component with mounting holes at its bottom that mate with anchor bolts, used to fix the wire rope fixing seat to the furnace platform foundation.

[0012] Preferably, the adjusting spring assembly includes an adjusting spring, a fixed seat, a screw, and a fixing nut. One end of the adjusting spring is connected to the wire rope assembly, and the other end of the adjusting spring is connected to the fixed seat via the screw. The fixing nut is used to adjust the extension length of the screw, and the fixed seat is fixed on the wire rope fixing seat.

[0013] Preferably, the intelligent alarm system includes a laser transmitter, a reflector, and a safety cover. The laser transmitter and the reflector are arranged opposite each other to form a light path, and the safety cover is installed outside the laser transmitter and the reflector. When an operator approaches the edge of the furnace and blocks the light path, the laser transmitter triggers an audible and visual alarm.

[0014] Preferably, the guardrail is 1200mm high, the wire rope assembly includes three wire ropes, which are evenly arranged vertically with a spacing of 400mm. The wire ropes correspond one-to-one with the three sets of support wheels of the movable support wheel assembly, and each set of movable support wheel assembly is provided with a proximity switch at the front and rear. The proximity switches are electrically connected to the control system and are used to control the raising or lowering of the movable support wheel assembly.

[0015] A method for manufacturing a smart flexible coke oven platform safety guardrail includes the following steps: Step 1: Install the wire rope fixing bracket and follower pulley assembly Two sets of wire rope fixing seats are fixed to the foundation at both ends of the furnace platform with anchor bolts. According to the design position, the follower pulley assembly is fixed to the corresponding position of the wire rope fixing seat with connecting bolts to ensure that the pulley axis of the follower pulley assembly is consistent with the preset wire rope path.

[0016] Step 2: Install the drive pulley assembly Based on the structural dimensions of the coke car, several drive pulley assemblies are fixed to corresponding positions on the front and rear sides of the coke car using connecting bolts. This ensures that the pulleys of the drive pulley assembly match the height of the follower pulley assembly, and that the wire rope can pass smoothly through the effective space between the coke car and the side of the furnace platform. The drive motor is then adjusted to ensure that the linear velocity of each drive pulley assembly matches the running speed of the coke car.

[0017] Step 3: Arrange the movable support wheel set Between the two wire rope fixing seats, several sets of movable support wheel sets are arranged on the side of the furnace platform steel structure frame at preset intervals. The first pin and the electro-hydraulic actuator support are welded to the side of the furnace platform steel structure frame. The swing frame is connected to the furnace platform steel structure frame through the first pin. The electro-hydraulic actuator is installed between the electro-hydraulic actuator support and the swing frame. The rotary motor and electro-hydraulic actuator are adjusted to ensure that the support wheels can rotate flexibly and that the movable support wheel sets can rise or fall smoothly. Proximity switches are installed in front of and behind the movable support wheel sets and connected to the control system.

[0018] Step 4: Install the wire rope assembly and adjusting spring assembly The wire rope is passed sequentially through the follower pulley assembly, the drive pulley assembly, and the support wheel of the movable support wheel group to form a continuous protective cable. The connection points of the wire rope are fixed with wire rope clamps. One end of the adjusting spring of the adjusting spring assembly is connected to both ends of the wire rope, and the other end is fixed to the wire rope fixing seat through the fixing seat. The preload of the adjusting spring is adjusted by the screw and the fixing nut to ensure that the wire rope is taut and does not swing out of the use range.

[0019] Step 5: Install the intelligent alarm system Install laser transmitters and reflectors in the pre-defined warning areas on both sides of the coke car near the edge of the furnace platform, so that the two form a complete optical path. Install safety protective covers on the outside of the laser transmitters and reflectors, connect the laser transmitters to the audible and visual alarm device, and debug the alarm system to ensure that an audible and visual alarm can be issued in time when the optical path is blocked.

[0020] Step Six: System Integration Debugging Start the coke car operation and check whether the proximity switch of the movable support wheel assembly can be accurately triggered. Ensure that when the coke car approaches, the movable support wheel assembly can rotate the support wheel and fall according to the preset program. After the coke car leaves, it can rise and reset the support wheel. Check whether there is relative slippage between the drive pulley assembly and the wire rope to ensure that the two operate synchronously. Test the response sensitivity of the intelligent alarm system and verify the safety protection effect of the entire guardrail.

[0021] The beneficial effects of this invention are as follows: 1. Improve the timeliness and reliability of safety protection: The intelligent alarm system forms a light path through the laser transmitter and reflector. When personnel approach the edge of the furnace platform and block the light path, an audible and visual alarm can be triggered immediately, solving the problem of delayed response in traditional manual inspections. Three steel wire ropes are evenly arranged vertically to form a three-dimensional protection, which is precisely supported by the support wheels of the movable support wheel group to effectively prevent personnel from falling. In addition, the safety guard protects the laser device from environmental interference, ensuring stable early warning and greatly reducing safety hazards. 2. Enhanced adaptability and efficiency of the protective structure: The drive motor of the drive pulley assembly drives the second pulley to run synchronously with the coke car, avoiding relative slippage between the wire rope and the coke car, ensuring smooth movement of the coke car. The movable support wheel group senses the position of the coke car through a proximity switch, and the rotary motor drives the support wheel to rotate 90 degrees and raises and lowers it through an electro-hydraulic push rod. When the coke car approaches, it falls to avoid it, and rises and resets after it leaves. No manual intervention is required, which solves the problem of fixed guardrails obstructing the operation of the coke car and improves work efficiency. 3. Ensuring the stability and durability of the protection system: The adjusting spring assembly adjusts the preload through the screw and the fixing nut to ensure that the wire rope is always taut and does not sag, avoiding the risk of breakage due to slack or overtightness. The bearings and oil cups of the follow-up pulley assembly reduce friction loss, and the through cover and end cover of the drive pulley assembly protect the bearings from contamination, extending the equipment life. The overall structure ensures the coordination of all components through system linkage debugging, adapting to complex scenarios such as multi-furnace door operation and improving long-term operational stability.

The drive pulley assembly 4 is fixed to the steel structure frame of the coke car by connecting bolts. The wire rope fixing seat 5 is fixed to the furnace platform by anchor bolts. The adjusting spring assembly 6 is located at both ends of the wire rope assembly 3 and fixed to the corresponding position of the wire rope fixing seat 5. The intelligent alarm system 7 is set on both sides of the coke car near the edge of the furnace platform. The follower pulley assembly 1 includes a first pulley 17, a first pulley bracket 19, a first drive shaft 18, a bearing 33, an oil cup 34, a cap 35, a bearing seat 36, a set screw 37, and a key 38. The first pulley 17 is mounted on the pulley bracket 19 via the first drive shaft 18. The drive shaft 18 and the pulley bracket 19 are connected by the bearing 33. The bearing 33 has a cap 35 and a bearing seat 36 on both sides. The oil cup 34 is disposed on the bearing seat 36. The set screw 37 and the key 38 are used to fix the drive shaft 18 and the pulley 17. The movable support wheel assembly 2 includes support wheels 8, support columns 9, slewing bearings 10, slewing motors 11, pin 12, swing frame 13, pin 2 14, electro-hydraulic actuators 15, and electro-hydraulic actuator supports 16. The support wheels 8 are evenly arranged in three groups on the support columns 9 with a spacing of 400 mm. The support columns 9 are connected to the swing frame 13 through the slewing bearings 10. The slewing motor 11 drives the slewing bearings 10 to rotate. The swing frame 13 is connected to the side of the furnace platform steel structure frame through pin 12. One end of the electro-hydraulic actuator 15 is connected to the swing frame 13 through pin 2 14, and the other end of the electro-hydraulic actuator 15 is mounted on the electro-hydraulic actuator supports 16. Pin 12 and electro-hydraulic actuator supports 16 are welded to the side of the furnace platform steel structure frame. The wire rope assembly 3 includes a wire rope 20 and a wire rope clamp 21, and the wire rope clamp 21 is used to fix the connection part of the wire rope 20. The wire rope 20 shuttles between the follower pulley assembly 1 and the drive pulley assembly 4 to form a protective structure. The drive pulley assembly 4 includes a second pulley 22, a second pulley bracket 23, a second drive shaft 24, a drive motor 25, a cover 32, a bearing 33, an oil cup 34, a cap 35, a bearing seat 36, a set screw 37, and a key 38. The second pulley 22 is mounted on the second pulley bracket 23 via the second drive shaft 24, and the drive motor 25 is connected to the second drive shaft 24 and drives it to rotate. The second drive shaft 24 and the second pulley bracket 23 are connected via the bearing 33, and a cover 32 and a cap 35 are respectively provided on both sides of the bearing 33. The oil cup 34 is provided on the bearing seat 36, and the set screw 37 and the key 38 are used to fix the second drive shaft 24 and the second pulley 22. The wire rope fixing seat 5 is a welded structural component, and its bottom is provided with mounting holes that cooperate with anchor bolts, for fixing the wire rope fixing seat 5 to the furnace platform foundation.

[0026] Through the above scheme, the structural design of each device provides a stable physical foundation for the guardrail. The bearing 33 of the follower pulley assembly 1 reduces the friction between the first drive shaft 18 and the bracket. The oil cup 34 facilitates the addition of grease, ensuring that the first pulley 17 rotates flexibly and that the wire rope 20 passes smoothly. The three sets of support wheels 8 of the movable support wheel group 2 correspond one-to-one with the three wire ropes 20. The rotation and lifting of the support wheels 8 are realized by the rotary motor 11 and the electro-hydraulic push rod 15, which can not only stably support the wire rope 20, but also avoid interference when the coke car approaches. The drive motor 25 of the drive pulley assembly 4 ensures that the second pulley 22 rotates synchronously with the coke car. The through cover 32 and the blind cover 35 prevent dust from entering the bearing 33 and extend its service life. The wire rope fixing seat 5 is fixed by the anchor bolts, providing a solid support for the overall structure. The wire rope clamp 21 ensures the strength of the connection part of the wire rope 20 and prevents breakage.

The wire rope assembly 3 shuttles and winds between the following pulley assembly 1 and the drive pulley assembly 4, and passes through the effective space on the side of the coke car and the furnace platform. The drive pulley assembly 4 is fixed to the steel structure frame of the coke car by connecting bolts. The wire rope fixing seat 5 is fixed to the furnace platform by anchor bolts. The adjusting spring assembly 6 is located at both ends of the wire rope assembly 3 and fixed to the corresponding position of the wire rope fixing seat 5. The intelligent alarm system 7 is set on both sides of the coke car near the edge of the furnace platform. The adjusting spring assembly 6 includes an adjusting spring 26, a fixed seat 27, a screw 28, and a fixing nut 29. One end of the adjusting spring 26 is connected to the wire rope assembly 3, and the other end of the adjusting spring 26 is connected to the fixed seat 27 via the screw 28. The fixing nut 29 is used to adjust the extension length of the screw 28, and the fixed seat 27 is fixed on the wire rope fixing seat 5. The intelligent alarm system 7 includes a laser transmitter 30, a reflector 31, and a safety cover 39. The laser transmitter 30 and the reflector 31 are arranged opposite each other to form a light path, and the safety cover 39 is installed outside the laser transmitter 30 and the reflector 31. When an operator approaches the edge of the furnace and blocks the light path, the laser transmitter 30 triggers an audible and visual alarm. The guardrail is 1200mm high. The wire rope assembly 3 includes three wire ropes 20, which are evenly arranged vertically with a spacing of 400mm. The wire ropes 20 correspond one-to-one with the three sets of support wheels 8 of the movable support wheel assembly 2. Each set of movable support wheel assembly 2 is equipped with a proximity switch at the front and rear. The proximity switches are electrically connected to the control system and are used to control the raising or lowering of the movable support wheel assembly 2. A method for manufacturing a smart flexible coke oven platform safety guardrail includes the following steps: Step 1: Install the wire rope fixing bracket and follower pulley assembly Two sets of wire rope fixing seats 5 are fixed to the foundations at both ends of the furnace platform with anchor bolts. According to the design position, the follower pulley assembly 1 is fixed to the corresponding position of the wire rope fixing seat 5 with connecting bolts to ensure that the pulley axis of the follower pulley assembly 1 is consistent with the preset wire rope path.

[0028] Step 2: Install the drive pulley assembly Based on the structural dimensions of the coke car, several drive pulley assemblies 4 are fixed to corresponding positions on the front and rear sides of the coke car using connecting bolts. This ensures that the pulleys of the drive pulley assembly 4 match the height of the pulleys of the follower pulley assembly 1, and that the wire rope can pass smoothly through the effective space between the coke car and the side of the furnace platform. The drive motor 25 is then adjusted to ensure that the linear velocity of each drive pulley assembly 4 matches the running speed of the coke car.

[0029] Step 3: Arrange the movable support wheel set Between the two wire rope fixing seats 5, several sets of movable support wheel groups 2 are arranged on the side of the furnace platform steel structure frame at preset intervals. The pin shaft 12 and the electro-hydraulic actuator support 16 are welded to the side of the furnace platform steel structure frame. The swing frame 13 is connected to the furnace platform steel structure frame through the pin shaft 12. The electro-hydraulic actuator 15 is installed between the electro-hydraulic actuator support 16 and the swing frame 13. The rotary motor 11 and the electro-hydraulic actuator 15 are adjusted to ensure that the support wheel 8 can rotate 90 degrees flexibly and that the movable support wheel group 2 can rise or fall smoothly. Proximity switches are installed in front of and behind the movable support wheel group 2 and connected to the control system.

[0030] Step 4: Install the wire rope assembly and adjusting spring assembly The wire rope 20 is passed sequentially through the follower pulley assembly 1, the drive pulley assembly 4, and the support wheel 8 of the movable support wheel group 2 to form a continuous protective cable. The connection points of the wire rope 20 are fixed with wire rope clamps 21. One end of the adjusting spring 26 of the adjusting spring assembly 6 is connected to both ends of the wire rope 20, and the other end is fixed to the wire rope fixing seat 5 through the fixing seat 27. The preload of the adjusting spring 26 is adjusted by the screw 28 and the fixing nut 29 to ensure that the wire rope 20 is taut and does not swing out of the range of use.

[0031] Step 5: Install the intelligent alarm system In the pre-set warning area on both sides of the coke car near the edge of the furnace platform, install a laser transmitter 30 and a reflector 31 to form a complete optical path. Install a safety cover 39 on the outside of the laser transmitter 30 and the reflector 31. Connect the laser transmitter 30 to the audible and visual alarm device and debug the alarm system to ensure that an audible and visual alarm can be issued in time when the optical path is blocked.

[0032] Step Six: System Integration Debugging Start the coke car operation and check whether the proximity switch of the movable support wheel assembly 2 can be accurately triggered to ensure that the movable support wheel assembly 2 can rotate the support wheel 8 and fall according to the preset program when the coke car approaches, and can rise and reset the support wheel 8 after the coke car leaves. Check whether there is relative slippage between the drive pulley assembly 4 and the wire rope 20 to ensure that the two operate synchronously. Test the response sensitivity of the intelligent alarm system 7 and verify the safety protection effect of the entire guardrail.

[0033] Through the above-mentioned scheme, the design of the adjusting spring assembly 6 and the intelligent alarm system 7 further enhances the practicality and safety of the guardrail. The adjusting spring 26 can flexibly adjust the preload through the screw 28 and the fixing nut 29 to compensate for the expansion and contraction of the wire rope 20 due to temperature changes or long-term use, ensuring that the protective rope is always in a stable tension state and avoiding the failure of protection caused by slack. The laser transmitter 30 and the reflector 31 of the intelligent alarm system 7 form an invisible warning boundary, and the safety protection cover 39 resists the influence of high temperature and dust, ensuring the stability of the light path. Once personnel approach, an alarm is triggered immediately to warn of danger in advance.

[0034] Each step of the manufacturing process ensures the accuracy of the device installation: Steps one and two ensure the compatibility between the foundation structure and the coke car; Step three adjusts the flexibility of the movable support wheel group 2; Step four ensures the connection strength and tension of the wire rope 20; Step five achieves reliable triggering of the alarm function; and Step six verifies the collaborative performance of each component through linkage debugging, ensuring that the overall system can stably play a protective role in scenarios such as coke car operation and multi-furnace door operation.

10. A method for manufacturing an intelligent flexible coke oven platform safety guardrail, using the intelligent flexible coke oven platform safety guardrail as described in claim 1, characterized in that, Includes the following steps: Step 1: Install the wire rope fixing bracket and follower pulley assembly Two sets of wire rope fixing seats (5) are fixed to the bases at both ends of the furnace platform with anchor bolts. According to the design position, the follower pulley assembly (1) is fixed to the corresponding position of the wire rope fixing seat (5) with connecting bolts to ensure that the pulley axis of the follower pulley assembly (1) is consistent with the preset wire rope path. Step 2: Install the drive pulley assembly According to the structural dimensions of the coke car, several drive pulley assemblies (4) are fixed at corresponding positions on the front and rear sides of the coke car by connecting bolts to ensure that the pulley of the drive pulley assembly (4) matches the pulley of the follower pulley assembly (1) in height, and that the wire rope can pass smoothly through the effective space between the coke car and the furnace platform. The drive motor (25) is adjusted to ensure that the linear speed of each drive pulley assembly (4) matches the running speed of the coke car. Step 3: Arrange the movable support wheel set Between the two wire rope fixing seats (5), several sets of movable support wheel groups (2) are arranged on the side of the furnace platform steel structure frame according to the preset interval length. The pin shaft (12) and the electro-hydraulic push rod support (16) are welded to the side of the furnace platform steel structure frame. The swing frame (13) is connected to the furnace platform steel structure frame through the pin shaft (12). The electro-hydraulic push rod (15) is installed between the electro-hydraulic push rod support (16) and the swing frame (13). The rotary motor (11) and the electro-hydraulic push rod (15) are adjusted to ensure that the support wheel (8) can rotate 90 degrees flexibly and the movable support wheel group (2) can rise or fall smoothly. Proximity switches (32) are installed in front of and behind the movable support wheel group (2) and connected to the control system. Step 4: Install the wire rope assembly and adjusting spring assembly The wire rope (20) is passed through the follower pulley assembly (1), the drive pulley assembly (4) and the support wheel (8) of the movable support wheel assembly (2) in sequence to form a continuous protective cable. The connection part of the wire rope (20) is fixed with a wire rope clamp (21).

The preload of the adjusting spring (26) is adjusted by the screw (28) and the fixing nut (29) to ensure that the wire rope (20) is taut and does not swing out of the range of use. Step 5: Install the intelligent alarm system In the pre-set warning area on both sides of the coke car near the edge of the furnace platform, install a laser transmitter (30) and a reflector (31) so that the two form a complete optical path. Install a safety guard (39) on the outside of the laser transmitter (30) and the reflector (31). Connect the laser transmitter (30) to the sound and light alarm device and debug the alarm system to ensure that a sound and light alarm can be issued in time when the optical path is blocked. Step Six: System Integration Debugging Start the coke car operation and check whether the proximity switch (32) of the movable support wheel assembly (2) can be accurately triggered. Ensure that the movable support wheel assembly (2) can rotate the support wheel (8) and fall according to the preset program when the coke car approaches. After the coke car leaves, it can rise and reset the support wheel (8). Check whether there is relative slippage between the drive pulley assembly (4) and the wire rope (20) to ensure that the two run synchronously. Test the response sensitivity of the intelligent alarm system (7) and verify the safety protection effect of the entire guardrail.
