Abstract
Description
Technical Field
[0001] This utility model relates to the field of maintenance depot protection technology, and in particular to an automatic protection device for a maintenance depot level crossing. Background Technology
[0002] As an important site for EMU maintenance, the maintenance depot has a complex on-site working environment, high frequency of EMU entry and exit, and a diverse range of participating units and personnel. Workers frequently pass through the maintenance depot's level crossing, which can easily lead to accidents such as personnel injury or forcing moving EMUs to stop due to human negligence or fatigue.
[0003] The existing protection measures for maintenance personnel entering and exiting the maintenance depot mainly rely on voice announcements and barrier gates. Simple sound and light alarms are insufficient to provide effective deterrence and lack immediate protection. While barrier gates offer physical obstruction, they cannot verify whether a train has fully entered or exited the maintenance depot level crossing before allowing further entry or exit. Furthermore, if a train has not fully entered or exited the depot, the barrier gates automatically retract once the entry / exit signal is turned off, failing to provide full-process protection for the level crossing during train entry and exit.

[0038] Figure 1 This is a schematic diagram of the structure of an automatic protection device for a maintenance depot level crossing, provided as an embodiment of the present invention. Figure 2 A schematic diagram of the structure of another automatic protection device for a maintenance depot level crossing provided in this embodiment of the utility model. See also... Figure 1and Figure 2 The automatic protection device 100 includes a control module 10, a barrier module 20, and a warning module 30. The control module 10 is connected to the EMU depot safety interlocking monitoring system 200 and is used to receive vehicle entry / exit signals indicating the level crossing of the maintenance depot. The barrier modules 20 are located on both sides of the level crossing and are connected to the control module 10. They are used to lower the barrier based on a first control signal output by the control module 10. Sensors are installed on the barrier modules 20 to collect vehicle entry / exit status and feed it back to the control module 10. The barrier modules 20 are also used to raise the barrier based on a second control signal output by the control module 10. The warning modules 30 are located on both sides of the level crossing and are connected to the control module 10. They are used to issue a first warning message.
[0039] Specifically, as a crucial location for EMU (Electric Multiple Unit) maintenance, the maintenance depot, and the level crossing, serving as the primary access point for maintenance personnel, are essential for preventing accidental entry or exit of maintenance personnel and vehicles when EMUs enter or leave the maintenance depot. This invention connects the control module 10 to the EMU depot safety interlocking monitoring system 200. The EMU depot safety interlocking monitoring system 200 is a system designed to ensure the safety of EMU maintenance and preparation operations, enabling real-time monitoring of the EMU's status. The control module 10 receives entry / exit signals from the EMU depot safety interlocking monitoring system 200, which indicate whether a vehicle is entering or leaving the maintenance depot level crossing. These entry / exit signals refer to the signals indicating whether an EMU is entering or leaving the maintenance depot level crossing. The barrier module 20 is connected to the control module 10 and is located on both sides of the maintenance depot level crossing. When vehicles enter or exit the level crossing, the barrier module 20 receives the first control information output by the control module 10 and lowers the barrier accordingly, achieving physical obstruction. Furthermore, the barrier module 20 is equipped with sensors that collect data on the entry and exit status of train sets at the level crossing and feed this data back to the control module 10. When a train set has fully entered or exited the level crossing, the barrier module 20 raises the barrier according to the second control information output by the control module 10, facilitating the passage of maintenance personnel and vehicles. The warning module 30 is also connected to the control module 10 and is located on both sides of the maintenance depot level crossing. When train sets enter or exit the level crossing, the warning module 30 issues a first warning message based on the entry / exit signal, alerting maintenance personnel. The first warning information can be set according to actual needs. This embodiment does not limit this. For example, the first warning information can be a voice broadcast saying "Attention all units, the EMU on track XX is about to leave / enter the maintenance depot. Please pay attention to safety." and broadcast three times, and display the words "No Entry" on both sides of the level crossing of the maintenance depot when the blocking device is lowered.
[0040] The technical solution provided in this embodiment of the utility model involves a control module connected to the EMU depot's safety interlocking monitoring system to receive EMU entry and exit signals. The blocking module lowers the barrier when the EMU enters or exits the maintenance depot based on these signals. Furthermore, the blocking module is equipped with sensors that can collect the EMU's entry and exit status, such as raising the barrier when the EMU has fully entered or exited the maintenance depot level crossing. Simultaneously, the warning module provides audible and visual warnings when the EMU enters or exits the depot. This utility model's automatic protection device achieves physical blocking through the blocking module while simultaneously providing audible and visual warnings to operators through the warning module. Moreover, by collecting vehicle entry and exit information through sensors on the blocking module, the control module can control the blocking module to retract the barrier after determining that the vehicle has fully entered or exited, allowing maintenance personnel and vehicles to pass, thus achieving automatic warning and protection functions.
[0041] Optional, Figure 3 This is a structural schematic diagram of another automatic protection device for a maintenance depot level crossing provided as an embodiment of the present utility model. Based on the above embodiment, see... Figure 2 and Figure 3 The automatic protection device also includes an identification module 40, which is connected to the control module 10, for identifying personnel information at the maintenance depot level crossing and outputting identification result signals to the control module 10; and an alarm module 30, which is also used to issue a second alarm message based on the identification result signal.
[0042] Specifically, the automatic protection device also includes an identification module 40, which is connected to the control module 10. The identification module 40 identifies personnel at the maintenance depot level crossing and outputs the identification result signal to the control module 10. When the automatic protection device 100 is deployed, the identification module 40 initiates personnel identification at the maintenance depot level crossing. If personnel are detected lingering at the level crossing during deployment, the identification result signal is immediately reported to the control module 10. The control module 10 then controls the barrier module 20 to retract the barrier, allowing lingering personnel to leave immediately. Simultaneously, the warning module 30 issues a second warning message based on the identification result signal. This second warning message can be set according to actual conditions; this embodiment does not limit its implementation. For example, the second warning message could be "The high-speed train is approaching; please leave as soon as possible." After the identification module 40 detects that the lingering personnel have left, the warning module stops issuing warnings, and the barrier module 20 immediately lowers the barrier, continuing to physically block the maintenance depot level crossing. The identification module 40 includes a camera located above the maintenance depot level crossing. The camera is connected to the control module 10 and acquires video recordings of the maintenance depot level crossing. When the system is armed, if personnel are detected loitering, the warning module 30 will issue a second warning message.
[0043] Optional, Figure 4This is a structural schematic diagram of another automatic protection device for a maintenance depot level crossing provided as an embodiment of the present utility model. Based on the above embodiment, see... Figure 2 and Figure 4 The blocking module 20 includes a first blocking unit 21 and a second blocking unit 22. The control module 10 is connected to the first blocking unit 21 and the second blocking unit 22 respectively. The first blocking unit 21 is located on one side of the maintenance depot level crossing, and the second blocking unit 22 is located on the other side of the maintenance depot level crossing, opposite to the first blocking unit 21.
[0044] Specifically, since the maintenance depot level crossing has passages at both ends of the track, barrier devices need to be installed on both sides of the level crossing. Therefore, the barrier module 20 of the automatic protection device 100 includes a first barrier unit 21 and a second barrier unit 22, and the control module 10 is connected to the first barrier unit 21 and the second barrier unit 22 respectively. The first barrier unit 21 is located on one side of the maintenance depot level crossing, and the second barrier unit 22 is located on the other side of the maintenance depot level crossing, and the first barrier unit 21 and the second barrier unit 22 are arranged opposite to each other.
[0045] Optionally, based on the above embodiments, see [link to relevant documentation]. Figure 2 and Figure 4 The first blocking unit 21 includes a first sensor 211 and a second sensor 212. The control module 10 is connected to the first sensor 211 and the second sensor 212 respectively. The first sensor 211 is located on the first side of the first blocking unit 10, and the second sensor 212 is located on the second side of the first blocking unit 21. The first side of the first blocking unit 21 is the side of the first blocking unit 21 that is close to the track, and the second side of the first blocking unit 21 is adjacent to the first side of the first blocking unit.
[0046] Specifically, the barrier module 20 is equipped with multiple sensors. A first sensor 211 and a second sensor 212 are installed on the first barrier unit 21. The first sensor 211 is located on the first side of the first barrier unit 21, and the second sensor 212 is located on the second side of the first barrier unit 21. The first side is the side of the first barrier unit 21 closest to the track, and the second side of the first barrier unit 21 is adjacent to the first side. The first sensor 211 is used to collect data on whether the train has completely entered or exited the maintenance depot level crossing. After detecting that the train has completely entered or exited the level crossing, it sends the train's entry / exit status to the control module 10. The control module 10 outputs a second control signal, and the first barrier unit 21 controls the barrier to rise according to the second control signal. The second sensor 21 is used to detect whether maintenance personnel and vehicles are passing below when the first blocking unit 21 is landing. If maintenance personnel and vehicles are detected, the first blocking unit 21 is controlled to automatically retract. When the maintenance personnel and vehicles leave the protected area, the first blocking unit 21 immediately falls.
[0047] Optionally, based on the above embodiments, see [link to relevant documentation]. Figure 2 and Figure 4 The second blocking unit 22 includes a third sensor 221 and a fourth sensor 222. The control module 10 is connected to the third sensor 221 and the fourth sensor 222 respectively. The third sensor 221 is located on the first side of the second blocking unit 22, and the fourth sensor 222 is located on the second side of the second blocking unit 22. The first side of the second blocking unit 22 is the side of the second blocking unit that is close to the track, and the second side of the second blocking unit 22 is adjacent to the first side of the second blocking unit.
[0048] Specifically, a third sensor 221 and a fourth sensor 222 are installed on the second barrier unit 22. The third sensor 221 is located on the first side of the second barrier unit 22, and the fourth sensor 222 is located on the second side of the second barrier unit 22. The first side is the side of the second barrier unit 22 closest to the track, and the second side of the second barrier unit 22 is adjacent to the first side. The third sensor 221 is used to collect data on whether the train has completely entered or exited the maintenance depot level crossing. After detecting that the train has completely entered or exited the maintenance depot level crossing, the entry / exit status of the train is sent to the control module 10. The control module 10 outputs a second control signal, and the second barrier unit 22 controls the barrier to rise according to the second control signal. The second sensor 21 is used to detect whether maintenance personnel or maintenance vehicles are passing below when the second barrier unit 22 is descending. If maintenance personnel or maintenance vehicles are detected, the second barrier unit 22 is controlled to automatically retract. When the maintenance personnel or maintenance vehicles leave the protected area, the second barrier unit 22 immediately falls. This embodiment of the utility model installs two sensors in the first blocking unit 21 and the second blocking unit 22 respectively to detect the entry and exit status of the EMU and the status of maintenance personnel and maintenance vehicles. This not only accurately determines the time of raising the barrier, but also realizes the anti-smashing function, further ensuring the safety of personnel.

[0050] Specifically, the warning module 30 includes a first warning unit 31 and a second warning unit 32, which are located on opposite sides of the track. The first warning unit 31 is located on the side of the maintenance depot level crossing closest to the first blocking unit 21, and the second warning unit 32 is located on the side of the maintenance depot level crossing closest to the second blocking unit 22. The first warning unit 31 is used to issue a first warning message on the side closest to the first blocking unit 21 when a train enters or leaves the maintenance depot, and to issue a second warning message when maintenance personnel are detected in the protected area during deployment. The second warning unit 32 is used to issue a first warning message on the side closest to the second blocking unit 22 when a train enters or leaves the maintenance depot, and to issue a second warning message when maintenance personnel are detected in the protected area during deployment.
