Technical Field
[0001] This utility model relates to the field of railway construction safety protection technology, and in particular to an electronic fence crossing sound and light alarm device for track construction personnel. Background Technology
[0002] Railway construction safety protection technology refers to a series of technical measures and methods adopted in the construction, maintenance and renovation of railways to ensure the personal safety of construction personnel, ensure the normal operation of railway equipment and facilities, and prevent interference and harm to railway transportation. A sound safety protection measure can create a safe and reliable working environment for construction personnel, enabling them to focus on construction tasks and improve work efficiency.
[0003] Existing railway construction safety protection measures mainly involve setting up protective fences. However, traditional protective fences have poor physical isolation flexibility and are difficult to adapt to frequent track construction operations in depots. Ordinary electronic fences have insufficient positioning accuracy in complex electromagnetic environments, such as weak GPS signals in metal structure areas. There are areas for improvement in existing technologies. Summary of the Invention
[0004] This utility model addresses the aforementioned shortcomings by providing a track construction worker electronic fence boundary crossing audible and visual alarm device, comprising: a safety helmet, an audible and visual alarm, a mounting box, and a pole. The mounting box is installed at the front end of the safety helmet, and the audible and visual alarm is fixedly installed at the top of the pole. The mounting box contains a positioning module for acquiring real-time location information of construction workers, and a storage module for pre-storing electronic fence coordinate data of an intercity railway depot. The positioning module and the storage module are connected to a controller for comparing the real-time location with the fence coordinates to generate a boundary crossing signal. An audible and visual alarm is externally connected to the controller for receiving the boundary crossing signal and issuing an audible and visual alarm. A power module is connected to the lower end of the controller. The positioning module is a UWB positioning module, and the electronic fence coordinate data includes dynamically adjusted construction restricted area and warning area boundaries. The mounting box is mounted on the safety helmet via a connecting seat.
[0005] Preferably, the connecting seat has an arc-shaped surface on the side away from the mounting box for fitting onto the safety helmet. The mounting box is provided with straps for fitting onto the safety helmet, with both ends of the straps fixedly disposed on both sides of the safety helmet. Each side of the safety helmet is fixedly provided with a pressure strip that presses against the outer wall of the safety helmet under the drive of the straps. The pressure strip is made of flexible material, and the two pressure strips are located within the space enclosed by the straps. One end of the pressure strip is fixedly disposed on the mounting box, and the end away from the mounting box has an opening through which the straps pass. The side of the pressure strip facing the safety helmet has several anti-slip strips, which are evenly distributed along the height direction on the pressure strip.
[0006] Preferably, the controller is also connected to a wireless communication module for sending boundary crossing signals to the depot DCC integrated system, the wireless communication module supporting both G and LoRa modes.
[0007] Preferably, the audible and visual alarm is installed beside the track via a pole, and is connected to a miniature buzzer located on the top of the safety helmet. The audible and visual alarm has a red and blue flashing function.
[0008] Preferably, the controller is also connected to an anti-interference module for filtering electromagnetic signal interference during train operation to avoid false alarms.
[0009] Preferably, the mounting box is provided with an outer cover plate, the mounting box and the outer cover plate are respectively provided with side blocks and the side blocks are connected by fixing bolts, and a sealing gasket is provided between the outer cover plate and the mounting box.
[0010] Preferably, the audible and visual alarm is provided with a mounting sleeve at the bottom, which is fitted onto the upright. The mounting sleeve has a mounting hole and a mounting bolt is connected between the mounting hole and the upright. The bottom of the upright is provided with a base.
[0011] Compared with existing technologies, this utility model incorporates a controller, a positioning module, a storage module, a wireless communication module, an anti-interference module, and a buzzer. The controller compares the real-time location with the fence coordinates to generate a boundary crossing signal. The positioning module acquires the real-time location information of construction personnel. The storage module pre-stores the electronic fence coordinate data of the intercity railway depot. The audible and visual alarm receives the boundary crossing signal and issues an audible and visual alarm. The anti-interference module filters electromagnetic signal interference from train operation. Through the combination of the above structures, dynamic boundary crossing alarm operations can be achieved. It can distinguish between "warning zones" and "prohibited zones," and issue graded alarms. Entering the warning zone triggers a flashing warning, while entering the prohibited zone triggers an audible and visual alarm plus a buzzer, ensuring the safety of construction personnel. It also has good flexibility, high precision, and anti-interference capabilities. Attached Figure Description

[0019] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:
[0020] like Figure 1-4 As shown, an electronic fence crossing alarm device for track construction workers includes: a safety helmet 1, an audible and visual alarm 2, a mounting box 3, and a pole 4. The mounting box 3 is installed at the front end of the safety helmet 1, and the audible and visual alarm 2 is fixedly installed at the top of the pole 4.
[0021] In this embodiment, the installation box 3 is equipped with a positioning module 6 for acquiring real-time location information of construction personnel, and a storage module 7 for storing pre-stored electronic fence coordinate data of the intercity railway depot. The positioning module 6 and the storage module 7 are connected to a controller 5 for comparing the real-time location with the fence coordinates to generate a boundary crossing signal. The controller 5 is externally connected to an audible and visual alarm 2 for receiving the boundary crossing signal and issuing an audible and visual alarm. The lower end of the controller 5 is connected to a power module 11. The positioning module 6 is a UWB positioning module. The electronic fence coordinate data includes dynamically adjusted construction restricted area and warning area boundaries. The controller 5 is also connected to a wireless communication module 8 for sending the boundary crossing signal to the depot's DCC integrated system. The wireless communication module 8 supports 4G and LoRa dual modes. The controller 5 is also connected to an anti-interference module 9 for filtering electromagnetic signal interference during train operation to avoid false alarms. Through the above structure, dynamic boundary crossing alarm operation can be realized, which can distinguish between "warning area" and "prohibited area", and provide graded alarms. Entering the warning area will trigger a flashing prompt, and crossing the prohibited area will trigger an audible and visual alarm plus a buzzer alarm, ensuring the safety of construction personnel. At the same time, it has good flexibility, high precision and anti-interference capabilities.
[0022] In this embodiment, the audible and visual alarm 2 is installed beside the track via a pole 4. The audible and visual alarm 2 is connected to a miniature buzzer 10 installed on the top of the safety helmet 1. The audible and visual alarm 2 has a red and blue flashing function. The bottom of the audible and visual alarm 2 is provided with a mounting sleeve 21, which is fitted onto the pole 4. The mounting sleeve 21 has a mounting hole 22, and a mounting bolt 23 connects the mounting hole 22 to the pole 4. The bottom of the pole 4 is provided with a base 41. The mounting sleeve 21 is fixed to the pole 4 through the mounting hole 22 and the mounting bolt 23. This allows for convenient installation and removal of the audible and visual alarm 2, making it easy to place the audible and visual alarm 2 beside the track and to disassemble and replace it, thus improving the flexibility of device maintenance. The audible and visual alarm 2 is equipped with a camera for capturing and detecting personnel behavior. It captures the behavior of people crossing the boundary in real time, assists in manual verification of alarm information, reduces false alarms, and the video data recorded by the camera can serve as evidence for tracing safety accidents, improving the traceability of safety management.
[0023] In this embodiment, an outer cover plate 31 is provided on the outside of the mounting box 3. Side blocks 32 are correspondingly provided on the sides of the mounting box 3 and the outer cover plate 31, and fixing bolts 33 connect the side blocks 32. A sealing gasket 34 is provided between the outer cover plate 31 and the mounting box 3. The outer cover plate 31 can be disassembled and assembled by the cooperation of the side blocks 32 and the fixing bolts 33, which allows the mounting box 3 to be opened quickly, facilitating the inspection, maintenance and adjustment of the internal circuit modules, and making future maintenance convenient.
[0024] like Figure 5 and Figure 6As shown, the mounting box 3 is mounted on the safety helmet 1 via a connecting seat 12. The connecting seat 12 has an arc-shaped surface 13 on the side away from the mounting box 3 for fitting onto the safety helmet 1. The mounting box 3 is provided with a strap 14 for fitting onto the safety helmet 1. The strap 14 is an elastic strap 14. The two ends of the strap 14 are respectively fixedly mounted on both sides of the safety helmet 1. Each side of the safety helmet 1 is fixedly provided with a pressure strip 15 that is pressed against the outer wall of the safety helmet 1 under the drive of the strap 14. The pressure strip 15 is made of flexible material, and the two pressure strips 15 are located within the space enclosed by the strap 14. One end of the pressure strip 15 is fixedly mounted on the mounting box 3, and the end away from the mounting box 3 has an opening 16 through which the strap 14 passes. The side of the pressure strip 15 facing the safety helmet 1 has several anti-slip strips 17, which are evenly distributed along the height direction on the pressure strip 15. During installation, the strap 14 is fitted onto the safety helmet 1. Since the safety helmet 1 has a large diameter, the strap 14 is always in a stretched state after being fitted. After the strap 14 is driven, the mounting box 3 is attached to the outer wall of the safety helmet through the connecting seat 12 with the arc surface 13. The pressure strips 15 on both sides of the mounting box 3 are firmly pressed against the outer wall of the safety helmet 1 under the drive of the strap 14, and the anti-slip strips 17 set on the pressure strips 15 abut against the safety helmet 1 to prevent the mounting box 3 from shifting.
[0025] The working principle and process of this utility model are as follows: When in use, the audible and visual alarm 2 is installed next to the track through the pole 4, and the control box 3 is installed at the front end of the safety helmet 1. When the construction personnel enter the warning zone, the audible and visual alarm 2 at the top of the pole 4 flashes to alert the construction personnel. When the construction personnel enter the 30-meter restricted area on the track, the buzzer 10 on the safety helmet 1 sounds an alarm, and at the same time, the audible and visual alarm 2 at the top of the pole 4 flashes, effectively alerting the construction personnel.
[0026] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications to the specification derived therefrom are still within the protection scope of this utility model.
