Description

Technical Field

[0001] This utility model relates to the field of railway safety protection technology, specifically to a fixed protection signal control system. Background Technology

[0002] In railway transportation operations, fixed protective signals (such as protective signs) are used to prevent shunting trains from accidentally entering dangerous areas and to ensure operational safety. Traditional protective signals are operated manually, which has the following problems:

[0003] 1. Inconvenient management: The application, unlocking, and removal of protection signals rely on manual registration, which is inefficient and prone to errors.

[0004] 2. Lack of status monitoring: It is impossible to monitor in real time whether the protection signal is in the correct locked or used state, which poses a safety hazard.

[0005] 3. Lack of coordinated early warning: The protective signals are not linked with the occupancy status of switches and shunting trains, making it difficult to provide timely warnings of dangerous situations.

[0006] Therefore, there is an urgent need for an automated and intelligent fixed protection signal control system to improve security and management efficiency. Utility Model Content

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a fixed protection signal control system, comprising:

[0011] The background program is used to realize remote electronic application, consent, electronic disclosure and automatic recording of usage of fixed protection signals;

[0012] The electronic occupancy indicator is used to display the status of the protection signal. When the protection signal is not locked, a warning sign is displayed at the corresponding track.

[0013] Furthermore, the shunting train occupancy monitoring device is a magnet, used to monitor the occupancy status of the shunting train.

[0014] Furthermore, the display and reminder device includes a display system installed in front of the protective signal track, used by shunting personnel to confirm the status of the protective signal in advance.

[0015] Furthermore, the background program is integrated into the station's electronic occupancy board, which automatically displays the usage status of the protection signal by collecting signals from the monitoring device, and supports remote one-click unlocking.

[0016] Furthermore, it also includes an alarm device that sends an alarm message to remind shunting personnel to stop the train when the protective signal has not been removed, the route is opened on the track, and the shunting train enters.

[0017] The advantages of the utility model compared to the prior art are:

[0018] 1. Improve safety: Monitor the status of protection signals in real time to avoid safety accidents caused by human error.

[0019] 2. Remote intelligent management: Through electronic application and one-click unlocking functions, manual intervention is reduced and work efficiency is improved.

[0031] Example 1: Application of Fixed Protection Signal Control System in Changle Station Freight Yard

[0032] 1. System Deployment

[0033] Automatic locking device installation: Electromagnetic locking devices are installed at the fixed protective signals (protective signs) in the freight yard and connected to the station control center. The protective signals are in the locked state (positioned) by default.

[0034] Monitoring device configuration:

[0035] A Hall sensor is installed at the pivot of the protective sign to monitor in real time whether the sign is raised or locked.

[0036] Magnets are installed in front of manual turnouts in non-centralized areas to monitor whether shunting trains enter the track.

[0037] Limit switches were installed at the gate of the freight yard to monitor the opening and closing status of the gate.

[0038] Display and alarm systems:

[0039] An LED display screen is installed in front of the track to dynamically display the status of the protection signal (e.g., "F" indicates that it is not locked).

[0040] Audible and visual alarms are installed in the shunting personnel's work area for hazard warning.

[0041] 2. Operating Procedures

[0042] Protection signal application and unlocking:

[0043] When freight personnel need to use protective signals, they can log in to the system via a handheld terminal or a fixed terminal and submit a usage application.

[0044] After receiving the application on the electronic track occupancy board, the station duty officer checks the track occupancy status and clicks the "Agree" button.

[0045] The system can remotely unlock the electromagnetic lock, and the protection signal can be manually raised for use.

[0046] Status monitoring and alarms:

[0047] If the protective signal is not removed (the locked state is not restored), and a shunting train approaches the track:

[0048] The magnet detected a train occupancy signal.

[0049] The system compares the switch position and the status of the protection signals to determine if there is a risk of conflict.

[0050] The LED screen displays "F" and an audible and visual alarm is activated to remind shunting personnel to stop the train.

[0051] Data Records:

[0052] The background program automatically records the application time, the person who approved it, the duration of use, and the removal time for each protection signal, generating an electronic ledger.

[0053] 3. Actual Results

[0054] Enhanced safety: Automatic monitoring and alarms prevent trains from accidentally entering the area due to the failure to remove protective signals.

[0055] Efficiency optimization: Remote electronic applications replace manual registration, reducing the time for a single operation from 5 minutes to 30 seconds.

[0056] Standardized management: Electronic records are traceable, solving the problems of easy loss and alteration of traditional paper ledgers.

[0057] Example 2:

[0058] Extended application of the system in areas with high shunting operation intensity

[0059] 1. Scene adaptation
