Description

Technical Field

[0001] This utility model belongs to the field of fire emergency equipment technology, and specifically relates to a dynamic sign for emergency evacuation routes. Background Technology

[0002] The production environment of aluminum electrolysis plants is extremely hazardous. High-temperature molten salt, strong currents, and flammable gases such as hydrogen pose multiple hidden dangers. Sudden events such as cell leaks, busbar short circuits, gas leaks, or fires can seriously threaten personnel safety. Regarding emergency evacuation guidance, existing devices are mostly fixed fire indicator lights or fluorescent signs, installed only in preset locations, providing only one direction and lacking dynamic adjustment. Especially given the large size of aluminum electrolysis plants and numerous intersections, existing guidance methods remain fixed and cannot be adjusted according to real-time situations.

[0003] Electrolysis plants operate in complex and ever-changing environments. In the event of a sudden accident, conventional fixed indicator devices are insufficient due to their limited versatility. For example, if an electrolytic cell leaks or a gas explosion occurs in a certain area, visibility is limited. Existing signs, which still follow fixed directions, may point to dangerous areas. Fixed indicator lights cannot adjust their direction in real time, which can easily lead to delayed evacuation and potential danger.

[0004] Currently, emergency evacuation in aluminum electrolysis plants still relies on manual broadcasts or on-site command to adjust routes. However, the workshops are noisy and have low visibility, and the efficiency of instantaneous decision-making in emergencies is limited, making it difficult to effectively guide employees to evacuate safely and increasing the risk of casualties. Therefore, there is an urgent need for an emergency guidance device that can adapt to the harsh environment of aluminum electrolysis plants, accommodate passageway intersections, and dynamically adjust evacuation directions in real time to improve evacuation efficiency. Utility Model Content

[0005] The purpose of this invention is to overcome the above-mentioned defects and propose a dynamic emergency evacuation route sign; to solve the problem that traditional static evacuation signs cannot adjust the evacuation guidance direction according to real-time environmental changes, especially for guiding passage intersections.

[0006] The specific technical solution is as follows:

[0007] A dynamic emergency evacuation route sign includes:

[0008] main body;

[0009] The sensor assembly includes a hydrogen concentration detection probe located at the top of the main body, and a non-contact infrared ranging sensor and a multi-directional infrared temperature measurement module located at the bottom of the main body.

[0010] The main control box is located on the top of the main body. Inside it is a microcontroller that is electrically connected to the sensor assembly and a storage module that stores instruction information. The microcontroller is connected to the communication module through a spring-loaded terminal.

[0011] A directional display component includes four independently driven LED arrays and a support bracket. The support bracket is coaxially positioned in the middle of the main body, and the LED arrays are arranged in a rectangular shape and mounted on the outer side of the support bracket. The output terminal of the microcontroller is electrically connected to the LED arrays.

[0012] The power supply compartment, located at the bottom of the main body, is used to house the power supply batteries.

[0013] Furthermore, the main body includes an upper body and a lower body, and the support bracket is rotatably connected to the upper body and the lower body respectively; the support bracket is provided with a hollow main shaft for data cable to pass through.

[0014] Furthermore, in the above scheme, the upper and lower bodies have a cylindrical structure.

[0015] Furthermore, the lower body is equipped with a drive motor, the output shaft of which is connected to a support bracket, and the drive motor is electrically connected to the single-chip microcomputer.

[0016] Furthermore, the directional display component further includes four directional laser emitters, which are mounted on the support bracket and oriented in the same direction as the LED array.

[0017] Furthermore, the directional laser emitter is equipped with a filter wheel to convert the white laser light from the directional laser emitter into red, green, or blue light.

[0018] Furthermore, the multi-directional infrared temperature measurement module includes four temperature measuring heads with germanium lenses, which are evenly distributed on the sides of the lower body and correspond to the LED light array.

[0019] Furthermore, the above scheme includes four infrared ranging sensors, which are evenly distributed on the sides of the lower body and correspond to the LED light array.

[0021] Furthermore, the upper surface of the main body is provided with a mounting bracket, and the top of the mounting bracket is provided with a mounting plate with mounting holes.

[0022] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0023] The main body of this utility model provides stable support for each component. The sensor assembly is used to capture environmental information. The microcontroller in the main control box is electrically connected to the sensor assembly and can link the storage module and communication module according to preset operations to control and realize the display. The four independent LED arrays of the directional display assembly are used to display and transmit directional information for different directions at the channel intersection, so as to realize emergency guidance.

[0024] This invention utilizes a drive motor to rotate the support bracket flexibly, combined with an independently driven LED light array and a directional laser emitter for aiming, and through the coordination of laser tri-color guidance and the LED light array, it clearly conveys safety guidance and danger warnings in low visibility conditions, enhancing the guidance effect.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0034] like Figure 1-5 As shown, this utility model discloses a dynamic emergency evacuation route sign, including a main body 1, sensor components, a main control box, a directional display component, and a power supply compartment 10. Through multi-sensor fusion detection and environmental perception, the directional display component dynamically displays the route, enabling dynamic adjustment of evacuation routes at intersections during sudden accidents in aluminum electrolysis plants. The main body 1 is divided into an upper body 11 and a lower body 12, with a cylindrical structure. The outer surface can be coated with a protective ceramic coating to withstand high-temperature corrosion. The sensor components include a hydrogen concentration detection probe 2 located at the top of the main body 1, and four non-contact infrared ranging sensors 3 and a multi-directional infrared temperature measurement module 4 located at the bottom of the main body 1, capable of comprehensively capturing environmental changes and generating data signals. The main control box is located at the top of the main body 1 and contains a microcontroller 5 electrically connected to the sensor components and a storage module 6 for storing instruction information. The microcontroller 5 is connected to a communication module 7 via spring-loaded terminals, forming the core control and communication hub. The directional display component includes four independently driven LED arrays 8, a support bracket 9, and four directional laser emitters 14. A support bracket 9 is coaxially positioned in the middle of the main body 1, rotatably connected to the upper body 11 and the lower body 12 respectively. The support bracket 9 has a hollow main shaft for data cable routing. An LED array 8 is arranged in a rectangle and mounted on the outside of the support bracket 9. A directional laser emitter 14 is mounted on the support bracket 9 and faces the same direction as the LED array 8. The directional laser emitter 14 has a filter wheel for converting white laser light into red, green, or blue light. The output of the microcontroller 5 is electrically connected to the LED array 8. A power supply compartment 10 is located at the bottom of the main body 1 and houses the power supply battery.

[0035] The lower end 12 of the main body 1 is equipped with a drive motor 13. The output shaft of the drive motor 13 is connected to the support bracket 9, and the drive motor 13 is electrically connected to the microcontroller 5, which can drive the support bracket 9 to rotate to adjust the indicated direction. The upper end face of the main body 1 is also equipped with a mounting bracket 17. The top of the mounting bracket 17 is equipped with a mounting plate with mounting holes for easy fixed installation of the device.

[0036] The four germanium lens temperature measuring heads of the multi-directional infrared temperature measuring module 4 correspond to the LED light array 8, enabling accurate detection of temperature in each indicated direction. A quartz protective tube can be fitted over the temperature measuring head, and the tube body is fixed to the main body 1 using a fluororubber sealing ring. Four non-contact infrared ranging sensors 3 correspond to the LED light array 8, employing prism reflection path design and other methods to accurately measure the distance to ground obstacles in each direction, indirectly indicating personnel movement and the unobstructedness of passageways.

[0037] The sensor assembly also includes a smoke sensor 15 and a vibration sensor 16, which detect the concentration of smoke in the air and abnormal vibration of the equipment, respectively, to achieve multi-dimensional monitoring. This addresses the problem that relying solely on hydrogen concentration, temperature, and distance detection is insufficient to comprehensively assess a hazard. By capturing smoke and vibration signals, it provides a more comprehensive understanding of the hazard and improves the reliability of evacuation guidance.

[0038] The circuit board of the microcontroller 5 inside the main control box can integrate an emergency path switching relay and a multi-channel optocoupler isolator to achieve secure signal isolation and transmission. The communication module 7 can use an embedded LoRa module and a WiFi 6 dual-band module. The signal antennas of the two modules can be arranged orthogonally, sharing a single coated ceramic substrate. The surface of this substrate can be etched with grounding grid isolation grooves, which are filled with conductive silicone sealant to effectively suppress communication interference. The microcontroller 5 achieves reliable connection through spring-loaded terminals. Its output directly drives the LED array 8 and the drive motor 13, forming a closed-loop feedback with the infrared ranging sensor 3.

[0039] Four LED light arrays 8 and corresponding directional laser emitters 14 form display guidance and laser guidance. When danger is detected, the microcontroller 5 adjusts the safety exit direction indication according to the pre-stored instructions, such as by turning the LED light arrays 8 on and off or displaying arrows, or by changing the color of the directional laser emitters 14, such as green indicating safety and red warning of danger, to enhance the warning effect.

[0040] This utility model's evacuation sign dynamically adjusts the evacuation direction by collaboratively monitoring environmental parameters using multiple sensors. It continuously collects key data such as hydrogen concentration, ambient temperature, and obstacle distance. When the hydrogen concentration exceeds a threshold or abnormally high temperatures are detected, the main control box immediately analyzes the data from each sensor and verifies the data using comparator circuits. After confirming a hazard, the system prioritizes activating the infrared ranging sensor 3 to scan the distribution of ground obstacles in all directions. Simultaneously, it acquires warning information from other nodes through the communication module 7. After integrating all data, the control terminal selects the optimal evacuation path, driving the corresponding LED light array 8 and directional laser emitter 14 to point in the target direction. A high-decibel alarm can be simultaneously emitted in conjunction with a buzzer, forming a combined visual and auditory warning. The evacuation path is a pre-stored selectable path, and a pre-stored table mapping key data such as hydrogen concentration, ambient temperature, and obstacle distance to the path, along with preset program settings for the operation of the LED light array 8 and laser emitter, is available. Those skilled in the art can implement this system. Figure 2-4 As shown, the LED light array 8 displays three different directional instruction graphics, such as left turn instruction, straight ahead instruction, and no-pass instruction.

[0041] In this solution, the microcontroller 5 is responsible for data reception, analysis, and instruction output. All operations are implemented based on existing technologies and do not involve program development. It receives data from various sensors using mature interface protocols and transmission methods. Based on the information pre-stored in the storage module 6, it analyzes the security level and uses conventional data processing logic. It controls the LED light array and laser emitter by outputting pre-stored display instructions. The drive motor 13 uses existing drive and circuit control technologies, and its connection with the communication module 7 also uses existing communication protocols.

[0042] In implementation, the sign is activated when an alarm is triggered. When the infrared ranging sensor 3 in a certain direction detects an obstacle within 3 meters for more than 10 seconds, the path switching logic is triggered. At this time, the microcontroller 5 controls the LED array 8 in the safe direction to light up and the directional laser emitter 14 to emit green light, while the LED array 8 in the dangerous direction is turned off and the laser emitter emits red light. Simultaneously, the communication module 7 is activated to send route update instructions to adjacent signs. The data of each sensor is refreshed in real time. A data table for selecting the path is preset in the storage unit. The corresponding display instruction strategy of the data table is selected according to different signal conditions to ensure real-time dynamic guidance under various dangerous conditions such as electrolyte leakage and fire spread. For example, when aluminum liquid leaks in the electrolytic cell area, the nearest sign detects the direction of the high-temperature heat source through the multi-directional infrared temperature measurement module 4. The microcontroller 5 controls the LED array 8 in the corresponding direction to turn off and the laser emitter 14 to emit red light, while the LED array 8 in the direction away from the heat source lights up and the laser emitter 14 emits green light. If the infrared ranging sensor 3 detects that the main channel is blocked by molten material, the indicating direction is automatically switched to the backup channel. The directional display component can also be driven by the drive motor 13, which can meet the guidance needs of complex channel junctions.

[0043] The above embodiments demonstrate various application scenarios of this dynamic signage in the complex environment of an aluminum electrolysis plant. Through dynamic signage, the safety and reliability of emergency evacuation are effectively improved. Those skilled in the art can make appropriate adjustments and improvements to the above embodiments according to actual needs, and such adjustments and improvements should all fall within the protection scope of this patent.
