Abstract
Description
Technical Field
[0001] This utility model relates to the field of alarm device technology, and more specifically, to a multi-level audible and visual alarm early warning device for high-speed railway construction sections. Background Technology
[0002] In the field of high-speed rail construction, because construction sections are usually distributed along long lines and involve complex terrain such as tracks, bridges, and tunnels, early warning and monitoring of safety risks such as personnel intrusion and equipment intrusion has always been a challenge in project management. Traditional construction early warning devices generally suffer from the following technical bottlenecks:
[0003] Existing devices mostly use a single sensor (such as a single microwave radar or camera) for monitoring, lacking a hierarchical filtering mechanism, resulting in a high false alarm rate. Most early warning devices are deployed at fixed points, limiting the monitoring angle and making it difficult to cover complex scenarios such as long lines, curves, and tunnels in high-speed rail construction. Especially at night or in inclement weather, cameras with fixed viewing angles are prone to monitoring failure due to insufficient lighting. In addition, the continuous monitoring and positioning accuracy of moving targets is insufficient. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a multi-level audible and visual alarm early warning device for high-speed railway construction sections, including a turntable and a top plate located above the turntable. A connecting rod connects the turntable and the top plate. A shaft assembly that rotates around the top plate is provided on the outside of the top plate. An outer warning component, a buffer warning component, and a core warning component are installed on the shaft assembly. An audible and visual actuator is installed on the outer wall of the shaft assembly. A drive component that drives the shaft assembly to rotate is installed on the top plate. A side support component that supports the shaft assembly is provided on the outside of the drive component.
[0005] In a preferred embodiment, the top plate is disc-shaped, and the shaft assembly includes a first bearing inner ring fixedly sleeved on the outside of the top plate, a movable first bearing outer ring sleeved on the outside of the first bearing inner ring, and a plurality of outwardly extending connecting rods connected to the outer wall of the first bearing outer ring, with connecting rings sleeved on the outer ends of the connecting rods.
[0006] In a preferred embodiment, a support ring plate is fixedly installed on the outer wall of the connecting ring, and a top cover covering the top plate, the inner ring of the first bearing, the outer ring of the first bearing, and the connecting rod is installed on the top of the connecting ring. A solar panel is installed on the top of the top cover.
[0007] In a preferred embodiment, the peripheral warning component includes a microwave radar mounted on the surface of the support ring plate, the buffer warning component includes an infrared thermal imaging lens mounted on the surface of the support ring plate, and the core warning component includes a visual camera mounted on the surface of the support ring plate.
[0008] In a preferred embodiment, the sound and light actuator includes a plurality of LED matrix beads uniformly fixed on the outer wall of the support ring plate.
[0009] In a preferred embodiment, the drive component includes a servo motor fixed to the surface of the turntable and a gear mounted on the top of the output shaft of the servo motor, and a gear ring meshing with the gear is mounted on the outer side wall of the outer ring of the first bearing.
[0010] In a preferred embodiment, the outer side of the servo motor is fitted with a protective cover fixed to the turntable. The inner side of the protective cover also has an external speaker unit and a battery. The side support includes a second bearing inner ring fixed to the bottom of the support ring plate and a second bearing outer ring movably fitted outside the second bearing inner ring. A lateral support rod is connected between the second bearing outer ring and the protective cover.
[0011] In a preferred embodiment, a vertical pole is connected to the bottom of the turntable, a base is installed at the bottom of the vertical pole, and a drive wheel is installed at the bottom of the base.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] 1. This utility model uses three levels of filtering—microwave radar, infrared thermal imaging, and visual camera—to significantly reduce the false alarm rate and ensure that alarms are only issued for real threats.
[0014] 2. The continuous rotation of the shaft assembly allows the sensor to cover a radius of tens of meters, eliminating blind spots in traditional fixed-point monitoring. It is especially suitable for high-speed rail construction sections with long lines and complex terrain. During the rotation, it can continuously lock onto moving targets and update location information in real time, facilitating rapid response by security personnel.
[0015] 3. By combining light signals with color and flashing and frequency changes in sound signals, light signals can effectively attract people's attention in complex environments such as bright light and noise, shorten reaction time, and gradually increase signal strength from warning to alarm, which conforms to the human perception of danger and avoids attention fatigue caused by continuous high-intensity alarms.

Detailed Implementation
[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.
[0021] like Figure 1-3 The multi-level audible and visual alarm and early warning device for high-speed railway construction sections shown includes a turntable 1 and a top plate 2 located above the turntable 1. A connecting rod 26 connects the turntable 1 and the top plate 2. A shaft assembly that rotates around the top plate 2 is provided on the outside of the top plate 2. The shaft assembly is equipped with an outer warning component, a buffer warning component, and a core warning component. An audible and visual actuator is installed on the outer wall of the shaft assembly. A drive component that drives the shaft assembly to rotate is installed on the top plate 2. A side support component that supports the shaft assembly is provided on the outside of the drive component.
[0022] Based on the above, the device drives the shaft assembly to rotate 360 degrees via a drive component, enabling the installed multi-level sensors (peripheral early warning components, buffer early warning components, and core early warning components) to perform a comprehensive scan of the high-speed rail construction section. When an anomaly is detected, an alarm signal of the corresponding level is issued through an audible and visual actuator, while the stable operation of the device is ensured by the power supply system and side support components.
[0023] The top plate 2 is disc-shaped. The shaft assembly includes a first bearing inner ring 3 fixedly sleeved on the outside of the top plate 2, and a movable first bearing outer ring 4 sleeved on the outside of the first bearing inner ring 3. Several outwardly extending connecting rods 5 are connected to the outer wall of the first bearing outer ring 4, and a connecting ring 6 is sleeved on the outer end of the connecting rod 5.
[0024] A support ring plate 7 is fixedly installed on the outer wall of the connecting ring 6. A top cover 8 covering the top plate 2, the inner ring 3 of the first bearing, the outer ring 4 of the first bearing, and the connecting rod 5 is installed at the top of the connecting ring 6. A solar panel 9 is installed on the top of the top cover 8.
[0025] The solar panel 9 on the top of the cover 8 converts light energy into electrical energy, which is stored in the battery 19 to power the servo motor 14, sensors, sound and light components, etc., thus achieving green energy saving.
[0026] The driving component includes a servo motor 14 fixed on the surface of the turntable 1 and a gear 15 mounted on the top of the output shaft of the servo motor 14. A gear ring 16 that meshes with the gear 15 is mounted on the outer side wall of the outer ring 4 of the first bearing.
[0027] Based on the above, the servo motor 14 is fixed to the turntable 1, and the gear 15 at the top of its output shaft meshes with the gear ring 16 on the outer side of the first bearing outer ring 4. After the servo motor 14 is started, it drives the first bearing outer ring 4 to rotate around the first bearing inner ring 3 through the gear 15, and then drives the connecting ring 6 and the support ring plate 7 to rotate synchronously through the connecting rod 5, so as to realize the sensor's 360-degree scanning without dead angles.
[0028] The peripheral early warning component includes a microwave radar 10 mounted on the surface of the support ring plate 7, the buffer early warning component includes an infrared thermal imaging lens 12 mounted on the surface of the support ring plate 7, and the core early warning component includes a visual camera 12 mounted on the surface of the support ring plate 7.
[0029] The sound and light actuator includes a number of LED matrix beads 13 that are uniformly fixed on the outer wall of the support ring plate 7. The LED matrix beads 13 are evenly distributed and the warning level is distinguished by different colors and flashing modes.
[0030] Based on the above, the microwave radar 10 provides peripheral early warning. It is installed on the surface of the support ring plate 7 and uses electromagnetic waves to detect distant areas. When a moving object (such as a person or vehicle) is detected entering the preset warning range, a signal is sent to the control system to trigger a preliminary warning, such as the LED matrix light bead 13 turning yellow and the external speaker unit 18 emitting a low-frequency alarm.
[0031] The infrared thermal imaging lens 12 performs secondary confirmation, conducting a second detection on the target locked by the microwave radar 10, and distinguishing biological heat sources (such as the human body) from non-biological objects (such as machinery) based on temperature characteristics. If the target is confirmed to be a human body, a medium-level warning is triggered (the LED light beads flash more frequently and the alarm tone is raised), and the visual camera 12 is activated to capture high-definition images.
[0032] The visual camera 12 performs image recognition on the target and uses AI algorithms to determine whether it is a construction worker (such as someone wearing a safety helmet or reflective clothing) or an unauthorized intruder. If it is determined to be an abnormal intrusion, the highest level alarm is triggered (the LED beads flash red light, the external speaker unit 18 emits a high-frequency alarm and broadcasts a voice warning, such as "Danger area, do not approach!"), and the image and location information are transmitted to the construction monitoring center in real time.
[0033] The outer side of the servo motor 14 is fitted with a protective cover 17 fixed on the turntable 1. The inner side of the protective cover 17 also has an external speaker unit 18 and a battery 19. The side support includes a second bearing inner ring 20 fixed to the bottom of the support ring plate 7 and a second bearing outer ring 21 movably fitted outside the second bearing inner ring 20. A lateral support rod 22 is connected between the second bearing outer ring 21 and the protective cover 17.
[0034] Based on the above, the side support includes a second bearing inner ring 20 fixed to the bottom of the support ring plate 7 and a second bearing outer ring 21 on the outside. It is connected to the protective cover 17 through the side support rod 22 to counteract the centrifugal force during rotation and ensure the smooth operation of the device.
[0035] The bottom of the turntable 1 is connected to a pole 23, and a base 24 is installed at the bottom of the pole 23. A drive wheel 25 is installed at the bottom of the base 24, which facilitates the rapid movement of workers and the deployment of devices at fixed points within the construction area.
[0036] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model.
