Description

Technical Field

[0001] This utility model relates to the technical field of train early warning systems, specifically to an unmanned train crossing early warning system. Background Technology

[0002] Railway transportation, as an important mode of transport, undertakes a large number of passenger and freight transport tasks. As the infrastructure of railway transportation, the safety and stability of railway tracks are directly related to the operational safety of trains and the efficiency of transportation.

[0003] For example, Chinese patent application CN1760071A discloses a method and device for early warning of unmanned railway crossings. This device includes a ground sensor at the road end, an infrared sensor at the railway end, an audio-visual device and a camera at the crossing, and image monitors installed at the dispatching and monitoring center and on the train. When no train is passing, vehicles on the road touch the ground sensor before entering the crossing, triggering the audio-visual device to warn of safety. When a train enters, the infrared sensor detects the locomotive axle temperature and triggers an alarm with the audio-visual device. Drivers can see the crossing image on the monitor and take immediate action in case of danger. The device includes a ground sensor and an infrared sensor, which are connected to the audio-visual device via radio signals. The camera is connected to a wireless video transmitter station via wired electrical signals. The wireless base station transmits video signals and connects to the image monitors. This method and device achieve fully automated management.

[0004] However, the above-mentioned device still has certain drawbacks in use: the device only uses sound and light warnings to block pedestrians and vehicles, and there is still a possibility that children and others may run onto the tracks, thus failing to fully guarantee the safety of train operation. Utility Model Content

[0005] This invention provides an unmanned railway crossing early warning system to solve the technical problem that existing crossing early warning devices cannot completely block pedestrians and vehicles, thus affecting train safety.

[0006] To solve the above problems, the present invention provides an unmanned railway crossing early warning system, which adopts the following technical solution:

[0007] An unattended railway crossing early warning system includes a railway track extending in a left-right direction. Two retaining walls extending forward and backward are installed on both sides of the railway track. Retractable barriers extending left and right are installed on both sides of the railway track and between the two retaining walls to prevent others from entering the railway track when a train passes through. Position sensors for detecting the train's position are installed at both ends of the railway track to control the retractable barriers to close the passage when the train approaches. Laser lights for warning pedestrians are also installed on both sides of the railway track, and a grating sensor for detecting pedestrians is installed on one side of the laser lights.

[0008] Its beneficial effects are as follows: by setting up retractable barriers on both sides of the train track, the possibility of pedestrians and vehicles entering the train track when the train is approaching is eliminated, thus improving the safety of train operation. The setting of position sensors enables the train to automatically control the opening and closing of the retractable barriers, realizing the automatic operation of the equipment and improving the convenience of equipment operation.

[0009] Furthermore, video modules are installed on the retaining walls on both sides of the train track to monitor the passage of the train.

[0010] Furthermore, an audible and visual alarm is installed on the retaining wall in front of the train track to issue an alarm signal to pedestrians when the train approaches.

[0011] Furthermore, an infrared sensor is installed at the front end of the retaining wall behind the train track to detect whether there are pedestrians passing by on the train track.

[0012] Furthermore, communication modules are installed on the retaining walls on both sides of the train track. These communication modules are used to communicate with the train to inform the train driver of the detection results from the infrared sensing device.

[0013] Its beneficial effects are as follows: the setting of the communication module establishes a connection between the level crossing and the train, thereby enabling the train driver to take appropriate measures based on the pedestrian crossing situation, thus improving the safety of train operation.

[0014] Furthermore, the retractable barriers are all equipped with reflective fabric to warn pedestrians at night.

[0015] Furthermore, the position sensor is a metal sensor.

[0016] The beneficial effects of the unattended railway crossing early warning system provided by this utility model are:

[0017] 1. By installing retractable barriers on both sides of the train track, the possibility of pedestrians and vehicles entering the train track when the train is approaching is eliminated, thus improving the safety of train operation. The setting of position sensors enables the train to automatically control the opening and closing of the retractable barriers, realizing the automatic operation of the equipment and improving the convenience of equipment operation.

[0018] 2. The communication module establishes a connection between the level crossing and the train, enabling the train driver to take appropriate measures based on the pedestrian crossing situation, thereby improving the safety of train operation. Attached Figure Description

Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] The main concept of this utility model is to eliminate the possibility of pedestrians and vehicles entering the train track 1 when the train is approaching by setting telescopic barriers 3 on both the front and rear sides of the train track 1, thereby improving the safety of train operation. The setting of position sensor 11 enables the automatic control of the opening and closing of the telescopic barriers 3 by the train, realizing the automatic operation of the equipment and improving the convenience of equipment operation.

[0025] After introducing the basic principles of this utility model, various non-limiting embodiments of this utility model are described in detail below. Any quantity of elements in the accompanying drawings is for illustrative purposes only and not for limitation, and any naming is for distinction only and has no limiting meaning.

[0026] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0027] Example 1 of an unattended railway crossing early warning system provided by this utility model:

[0028] like Figure 1As shown, the system includes a train track 1, which extends in a left-right direction. Two retaining walls 2 extending in front and back are provided on both sides of the train track 1. Retractable barriers 3 extending in left and right are provided between the two retaining walls 2 on the front side and between the two retaining walls 2 on the rear side to close the level crossing when a train approaches. Reflective cloth 31 is provided at the front end of the front retractable barrier 3 and at the rear end of the rear retractable barrier 3. The reflective cloth 31 is used to warn pedestrians at night.

[0029] Position sensors 11 are provided at both ends of the train track 1. The position sensors 11 are metal sensors to control the opening and closing of the telescopic barrier 3 when the train approaches. The front and rear sides of the train track 1 are provided with grating sensors 4. The grating sensors 4 are used to detect the movement of pedestrians and vehicles. The front end of the front grating sensor 4 and the rear end of the rear grating sensor 4 are provided with laser lights 5. The laser lights 5 are used to warn pedestrians and vehicles when the train approaches.

[0030] In addition, video modules 22 for monitoring the level crossing are installed on the retaining wall 2 at the right end of the front side of the train track 1 and the retaining wall 2 at the left end of the rear side of the train track 1. The retaining wall 2 at the left end of the front side is equipped with an audible and visual alarm 23 to issue an alarm signal to pedestrians when the train approaches. The retaining wall 2 at the right end of the rear side is equipped with an infrared sensor 24 to detect whether there are pedestrians crossing the train track 1. Communication modules 21 are installed at the rear end of the front video module 22 and the front end of the rear video module 22. The communication modules 21 are used to communicate with the train to inform the train driver of the detection results of the infrared sensor 24, so that the train driver can take corresponding measures according to the pedestrian crossing situation, thereby improving the safety of train operation.

[0031] The system works as follows: First, when a train approaches, the position sensor 11 located at the right end of the train track 1 detects the train's approach and transmits the signal to the telescopic barrier 3, laser light 5, and audible and visual alarm 23, activating the audible and visual warnings and laser warnings at the level crossing. At this time, the telescopic barriers 3 on both sides of the train track 1 close the level crossing. During the level crossing closure process, the grating sensor 4 detects the pedestrian's position and broadcasts warning information through the audible and visual alarm 23. The infrared sensor 24 detects obstacle information on the train track 1 and transmits the level crossing situation to the train control room in real time through the communication module 21, so that the train driver can control the train's operation according to the actual situation. After the train passes through the level crossing, the position sensor 11 located at the left end of the train track 1 detects the train's departure signal and then controls the telescopic barrier 3, laser light 5, and audible and visual alarm 23 to close.

[0032] Embodiment 2 of the unattended railway crossing early warning system provided by this utility model:

[0033] Its main difference from Example 1 is:

[0034] In Example 1, the position sensor is a metal sensor.
