Description

Technical Field

[0001] This utility model relates to the field of safety protection system technology, and in particular to a railway operation safety protection system based on signal interlocking and satellite positioning. Background Technology

[0002] Railway work safety is a crucial measure to ensure the safety of train operations and personnel, and an important guarantee for safe production. During railway construction operations, the lack of protective measures or inadequate protection can seriously threaten the safety of train operations and the personal safety of workers, potentially leading to severe consequences and significant loss of life and property. Railway work safety protection systems are used to safeguard the safety of workers and railway operations.

[0003] Existing railway operation safety protection systems typically involve installing video surveillance equipment in the work area, with staff monitoring the area from a remote control room. When a locomotive is detected approaching the work area, an alarm system in the control room notifies the staff, who then immediately contact the workers by phone, instructing them to evacuate immediately to ensure their safety. However, this method only monitors the work area unilaterally, failing to provide real-time information on locomotive movement, and requires manual intervention from staff. This results in a relatively poor protective effect for railway operations.

[0004] In other words, the existing railway operation safety protection systems have the problem of poor protection effectiveness. Utility Model Content

[0058] The following is combined Figures 1 to 4 Here is a more complete embodiment of this application:

[0059] This utility model provides a railway operation safety protection system based on signal interlocking and satellite positioning, which includes a display screen, a frame, a handheld device, and a wireless signal transceiver module. Air guide plates are evenly fixed at the bottom of the frame, and a control box is installed at the bottom of the frame. A circuit board is installed inside the control box, and a wireless signal transceiver module, a central processing module, and a data storage module are installed sequentially from left to right on one side of the circuit board. A fan is installed inside the control box below the circuit board. A display screen is installed at the top of the frame. A handheld device and a second infrared camera are evenly installed at one end of the control box, and a first infrared camera, a speaker, a GPS positioning module, and a drone are evenly installed at the other end. The frame is made of stainless steel, and both the outer and inner walls of the frame are provided with rubber insulation layers. By providing rubber insulation layers on both the outer and inner walls of the frame, the anti-slip buffering performance and insulation effect of the frame are improved, enhancing the practicality of the device.

[0060] Specifically, ventilation plates 327 (set on the first and second heat dissipation vents) are welded to the top and bottom of the control box, and heat dissipation holes are evenly arranged on the ventilation plates. Dustproof filter cloth is fixed to the top and bottom of the ventilation plates. The dustproof filter cloth and the ventilation plates are bonded together. The material of the ventilation plates is aluminum alloy.

[0061] When in use, the fan inside the control box starts, driving the air inside the control box to flow. Combined with the function of the ventilation plate and the heat dissipation holes on it, the hot air generated by the operation of the electronic components inside the control box can be exchanged with the cooler air in the outside environment. This enables the control box to achieve a better air-cooling heat dissipation effect and reduces the heat loss of electronic components.

[0062] Specifically, the control box is made of aluminum alloy, and both the control box and the display screen are connected to the frame with screws to form a disassembly and installation structure; this optimizes the structure of the device, making it easy for users to disassemble and maintain the control box and display screen inside the frame.

[0063] Specifically, the air guide plate and the frame form an integrated welded structure, and a reserved air guide pipe is fixed on one side of the air guide plate, with a sealing plug threaded onto the reserved air guide pipe; this improves the robustness between the air guide plate and the frame through welding.

[0064] Specifically, both ends of the bottom of the air guide plate are welded with adsorption plates, the interior of the adsorption plates is connected to the interior of the air guide plate, and the bottom of the adsorption plates is uniformly provided with adsorption holes.

[0065] During use, the user can unscrew the sealing plug on the reserved air guide tube, and then use the air pump to extract the gas inside the air guide plate, thereby extracting the gas inside the adsorption plate that is connected to the inside of the air guide plate. This creates a negative pressure inside the adsorption holes evenly distributed at the bottom of the adsorption plate, which firmly adsorbs and fixes the device to the operating ground, thus enhancing the stability of the frame.

[0066] Specifically, the wireless signal transceiver module and the central processing module are connected bidirectionally by wires. The output of the central processing module is connected to the input of the display screen, the fan, and the data storage module by wires. The handheld device, the second infrared camera, the first infrared camera, and the GPS positioning module are connected bidirectionally to the central processing module. The output of the central processing module is connected to the input of the display screen, the speaker, and the drone.

[0067] Specifically, the handheld device can be model T60KM, the speaker can be model HX-225, the display screen can be model HD52100, both the second and first infrared cameras can be model IPC3601, the GPS positioning module can be model HW-623A, the central processing module can be model S7-200CN, the wireless signal transceiver module can be model AK-119S, the fan can be model XD2006, and the data storage module can be model CFM100.

[0068] The working principle of this protection system is as follows:

[0069] In use, an external power supply is required. The user first places the rack in a suitable operating position in the back-end workshop and assembles the display screen and control box inside the rack. Then, the user can use the central processing module on the control box to control a drone equipped with a camera and locator to move above the railway, creating a dedicated railway map through aerial photography. This facilitates targeted protection deployment for the corresponding railway lines. Based on the dedicated railway map, the user then constructs multiple monitoring sub-base stations along the railway line to be protected, installing a second infrared camera for monitoring on each sub-base station. Simultaneously, first infrared cameras are installed inside the locomotives traveling on the railway line. The locomotive is equipped with an infrared camera, speaker, and GPS positioning module. The locomotive's location and surrounding conditions are transmitted in real-time to the control box. The locomotive's internal speaker allows the control box to remotely send voice alarm data and railway worker location data to the speaker, which then alerts the driver. Furthermore, each worker on the railway line is equipped with a handheld device remotely connected to the control box. This handheld device uses a GPS / BeiDou locator, network communication module, and speaker to send location information to the control box. The system can also receive voice alarm signals remotely sent from the control box. In operation, this protection system can locate outdoor railway workers in real time, allowing train drivers to clearly know the workers' locations and work trajectories over a specific period. When personnel intrude into the restricted area, the train control console issues a voice alarm. When the train enters the personnel protection zone and approaches the work site, the handheld terminal broadcasts a voice alert, constantly reminding on-site personnel of the train's operational status. This achieves dual protection for both personnel and the train, enhancing safety. Furthermore, during use, the user can unscrew the pre-installed guide... The sealing plug on the air pipe, along with the air pump, draws out the gas from inside the air guide plate, which in turn draws out the gas from the adsorption plate connected to it. This creates a negative pressure inside the evenly spaced adsorption holes at the bottom of the adsorption plate, firmly adsorbing and fixing it to the operating ground, thus enhancing the stability of the frame. On the other hand, when the device is running, the fan inside the control box starts, driving the airflow inside the control box. Combined with the ventilation plate and the heat dissipation holes on it, the heat generated by the operation of the electronic components inside the control box can be exchanged with the cooler air in the outside environment. This allows the control box to achieve a better air-cooling effect and reduces the heat loss of the electronic components.

[0070] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
