[0020] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings. Example 1

[0021] The intelligent safety warning system applicable to rail transit train maintenance workshops of this utility model includes a centralized control terminal 1 and warning terminals. The centralized control terminal 1 is connected to several warning terminals simultaneously, and the warning terminals are correspondingly installed on the trench crossing passage 4.

[0022] Specifically, the warning terminal includes a control box 2 and a warning module 3. The control box 2 and the warning module 3 are connected. The control box 2 is connected to the centralized control terminal 1. The control box 2 is installed on a column on one side of the trench crossing channel 4, and the warning module 3 is installed directly above the trench crossing channel 4.

[0023] like Figures 1 to 3 As shown, Figure 1 This is a schematic diagram of the installation of the warning terminal; Figure 2 This is a structural view of the warning module; Figure 3 This is an exploded view of the structure of the warning module.

[0024] The warning module 3 includes a housing 31, a physical barrier, and warning lights 32. The housing 31 is a rectangular box structure, with one side of the housing 31 fixedly positioned above the trench crossing passage 4. The physical barrier is located inside the housing 31, and an isolation groove is provided at the bottom of the housing 31. The physical barrier includes a roller shutter 33 and an isolation motor 34. One end of the roller shutter 33 is located in the isolation groove, and the isolation motor 34 is fixedly positioned inside the housing 31. The roller shutter 33 and the isolation motor 34 are connected by a drive. By unwinding and rewinding the roller shutter 33 through the isolation motor 34, a physical barrier can be formed or retracted below the housing 31, thereby providing a warning and isolation operation at the entrance of the trench crossing passage 4 to prevent personnel from crossing the trench under dangerous conditions. At least two warning lights 32 are provided, and each warning light 32 displays a different color. Both the warning lights 32 and the isolation motor 34 are connected to the control box 2.

[0025] The control box 2 provides a stable power supply to the warning module 3, receives command signals from the centralized control terminal 1, and accurately transmits these signals to the warning module 3 to control various operations of the warning module 3.

[0026] The commands issued by the centralized control terminal 1 are safety commands and work commands. In the safety command state, the control box 2 controls the isolation motor 34 to drive the roller shutter 33 to roll up into the outer casing 31, and all warning lights 32 are turned off, allowing safe passage through the trench crossing 4. In the work command state, the control box 2 controls the isolation motor 34 to drive the roller shutter 33 to unroll, forming a physical barrier at the entrance of the trench crossing 4. The warning lights 32 of different colors are displayed according to the corresponding working conditions, such as emitting a yellow flashing light when the train is shunted and emitting a red flashing light when pressure is applied.

[0027] Generally, the roller shutter 33 is provided with a reminder sign, which is displayed after the roller shutter 33 is unrolled to form a physical barrier.

[0028] The warning module 3 also includes a sensor 35 and a horn 36. Both the sensor 35 and the horn 36 are fixedly mounted on the outer wall of the housing 31 and are connected to the control box 2. The sensor 35 monitors in real time whether any object enters the sensing area, i.e., whether any object approaches the warning module 3. Once an intrusion is detected, a corresponding warning action is immediately triggered. The horn 36 plays warning voice messages, such as "Train shunting, caution," "Train pressure resistance, caution," and "No intrusion," to remind workers to pay attention to safety in a voice format.

[0029] Specifically, the outer casing 31 includes a rear cover plate 311, a front end plate 312, a top plate, a bottom plate, and two side end plates. The top plate, the bottom plate, and the two side end plates are respectively vertically arranged on one side edge of the front end plate 312, thereby forming a box structure with side openings. The rear cover plate 311 is detachably connected to the opening position. The rear cover plate 311 and the front end plate 312 are arranged in parallel. The top plate is located on the top of the outer casing 31, and the bottom plate is located on the bottom of the outer casing 31. The isolation groove is located on the bottom plate. The roller shutter 33 is fixedly arranged on the rear cover plate 311 through a connecting seat, and the rear cover plate 311 is fixedly arranged directly above the trench passage 4. The sensor 35 and the warning light 32 are both arranged on the front end plate 312 to facilitate light reminders and the detection of personnel approaching. The speaker 36 is arranged on the bottom plate to facilitate voice broadcast reminders at the trench passage 4 located below the outer casing 31.

[0030] Both the roller shutter 33 and the isolation motor 34 adopt the conventional roller shutter 33 door structure in the prior art.

[0031] This utility model enables physical isolation and alarm activation of the warning module 3 and warning light 32 through remote control, effectively improving the safety of rail transit train maintenance workshops under conditions such as train entry and exit from the depot and pressure-resistant operations, reducing the probability of safety accidents, and improving the management efficiency of maintenance operations. Example 2

[0032] The intelligent safety warning system for rail transit train maintenance workshops also includes a relay module. The centralized control terminal 1 is connected to the warning terminal through the relay module. The relay module includes a housing, a power module, and a repeater. Both the power module and the repeater are housed within the housing and are connected to provide power. The centralized control terminal 1 is connected to the warning terminal through the repeater. The housing protects the internal components. The power module converts the AC220V workshop power supply to a power standard compatible with the repeater. The repeater is responsible for forwarding the command signals from the centralized control terminal 1, enhancing signal transmission distance and stability, and ensuring smooth wireless communication throughout the system.

[0033] The centralized control terminal 1 is a command issuing and signal receiving terminal. It sends commands to the warning terminal via wireless communication. After receiving the signal from the centralized control terminal 1, the warning terminal performs the corresponding action and feeds back its working status to the centralized control terminal 1 via wireless communication. For long transmission distances, the relay module can be set up on the transmission path to ensure the stability of wireless transmission.

[0034] like Figure 4 As shown, Figure 4 This is a structural view of the centralized control terminal. The centralized control terminal 1 includes a housing 11, a display screen 12, a switch 13, and a control module. The display screen 12 is embedded in the housing 11, the control module is disposed inside the housing 11, and the switch 13 is disposed on the housing 11. The display screen 12 and the switch 13 are both connected to the control module, and the control module is connected to each of the warning modules 3.

[0035] The switch 13 controls the overall opening and closing of the control module and the display screen 12. The control module receives the working status information of each warning module 3 and transmits it to the display screen 12 for display. The operator can issue instructions through the display screen 12, and the control module transmits the instructions to the corresponding warning module 3 to perform warning operations on the corresponding trench crossing channel 4.

[0036] This utility model has multiple working states to adapt to different operating conditions. Under normal operating conditions, the system is in the off state. At this time, the warning light 32 is not lit, the warning voice is not played, and the physical barrier remains in the raised state, so it will not interfere with normal workshop operations. When the train enters or leaves the depot, the centralized control terminal 1 sends a command to the relevant warning terminal. After receiving the command, the warning module 3 illuminates the yellow flashing light of the warning light 32, and at the same time, the speaker 36 plays the warning voice "Train shunting, be careful" and the physical barrier drops, forming a warning area in the trench crossing passage 4. If the sensor 35 detects an object entering the sensing area, the speaker 36 will immediately switch to playing the warning voice "No entry" to prevent personnel from entering the danger zone. When the train is undergoing pressure resistance operation, the system workflow is similar, but the warning light 32 turns into a red flashing light, the speaker 36 plays the warning voice "Train pressure resistance, be careful," and similarly plays the "No entry" voice warning when foreign object intrusion is detected.

[0037] The operating procedure of this utility model is as follows: When the equipment is powered on, the operator only needs to press the switch 13 button on the right side of the centralized control terminal 1, and the equipment will start automatically. After powering on, the display screen 12 shows the login interface. After the operator enters the correct account and password, they can enter the main page. The main page has corresponding function operation interfaces set according to the number of tracks in the workshop. For example, a system with 6 tracks has 6 function operation interfaces. Each interface has detailed function mode options for the first / second row warning terminals of that track, including the opening and closing control of train entry / exit mode and train pressure resistance mode. It can also operate the power switch 13 of the warning terminal and display its working status in real time. In addition, the system also has a dedicated system information interface for recording equipment operation records, storing alarm information, etc. When performing train entry / exit operations, the operator first selects the track to be operated, enters the corresponding operation interface, and then clicks the [Train Entry / Exit Open] button at the corresponding position of the first / second row. At this point, the system will sequentially issue commands to turn on the trench lights, the yellow warning light, and the warning voice, and to lower the physical barriers, according to preset logic. The "Current Status" area of ​​the operation interface will display the currently executed actions and status in real time. After the train's entry and exit operations are completed, the operator presses the "Train Entry / Exit Close" button on the operation interface, and the system will execute commands to turn off the yellow warning light, turn off the warning voice, raise the physical barriers, and turn off the trench lights. The operation of opening and closing the train pressure resistance mode is similar to that of the train entry / exit mode, achieved by operating the "Train Pressure Resistance On" and "Train Pressure Resistance Off" buttons. To check equipment fault information and equipment status, the operator only needs to click the "System Information" button to obtain detailed relevant information in the system information interface, facilitating timely detection and handling of equipment problems.

[0038] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
