[0028] With the above structure, by firmly installing the fixture on the rail 28 and adjusting the sensor group to a suitable position, the sensor group can detect the trains coming and going. When the first sensor 22 and the third sensor 29 detect the arrival of a train, the signal is transmitted to the receiver 24. After receiving the signal, the receiver 24 sends an audible and visual alarm to remind the level crossing attendant that the train is about to pass through the crossing, and at the same time starts the gate not closed controller to remind the attendant to immediately close the crossing gate 10 and stop the road 13 vehicles from passing through the crossing. When the receiver receives the signal that a train is about to pass through the crossing, the controller of the crossing gate 10 locks the gate opening controller. At this time, the attendant can only close the gate but cannot open it, even if there are multiple trains about to pass through the crossing. Only when all trains have completely passed through the level crossing for a period of time, the second sensor 23 and the fourth sensor 30 respectively send a train passing signal to release the locking of the crossing gate 10, and the attendant can smoothly open the gate and let the road 13 vehicles pass, thereby avoiding collision accidents caused by opening the gate incorrectly.
[0029] Specifically, the transmitter 25 is a 4G signal transmitter 25, and the two 4G signal transmitters 25 are respectively connected to the first sensor 22 and the third sensor 29, the first sensor 22 and the third sensor 29 are respectively used to detect the arrival of trains on the upstream railway track 11 and the downstream railway track 12, and send data to the server through the 4G signal transmitter 25.
[0030] Specifically, the receiver 24 is a 4G signal receiver 24, which is used to receive the signal sent by the 4G signal transmitter 25 and transferred by the server.
[0031] Specifically, the receiver 24 also includes an audible and visual alarm prompt and an alarm clearing sensor.
[0032] Specifically, 10 seconds after all trains have completely passed the level crossing, the second sensor 23 and the fourth sensor 30 respectively send out train passing signals to unlock the crossing gate 10. The crossing attendant can then successfully open the crossing gate 10 and allow vehicles on the highway 13 to pass, thereby avoiding accidents caused by the incorrect opening of the crossing gate 10.
[0033] In an embodiment of the utility model, the first adjustment seat includes a first mounting seat 14, a second mounting seat 15 and a first fastener 16.

[0034] The first mounting seat 14 and the second mounting seat 15 are respectively clamped on both sides of the rail 28 and fixed by the first fastener 16, wherein the first fastener 16 is composed of a stainless steel bolt and a bolt anti-loosening gasket, so that the fixture is firmly fixed on the rail 28 to prevent it from loosening due to the impact of the train.
[0035] In an embodiment of the utility model, the second adjustment seat includes a support seat 17 and a second fastener 18 . The support seat 17 is arranged on the top of the first mounting seat 14 . Two strip grooves 19 are provided on one side of the support seat 17 , and the support seat 17 is fixed by the second fastener 18 .
[0036] The second adjustment seat is fixedly mounted on the top of the first mounting seat 14 by a second fastener 18 , thereby providing support force for the subsequent installation of the fixing seat 20 .
[0037] In the embodiment of the utility model, the fixing seat 20 is L-shaped, and the fixing seat 20 is fixed to one side of the supporting seat 17 by two third fasteners 21, and the two third fasteners 21 are respectively embedded in the two strip grooves 19;
[0038] After the fixing base 20 is driven to move to a suitable height position along the strip groove 19 by the third fastener 21 , the third fastener 21 is tightened to fix the position of the fixing base 20 , thereby determining the position of the sensor so that the sensor can detect the vehicle.
[0039] In the embodiment of the utility model, it further comprises: two rubber pads 26; one end of the two rubber pads 26 is respectively connected to the inner wall of the mounting groove of the first mounting seat 14 and the second mounting seat 15, and the other end of the rubber pads 26 is respectively fitted to the two ends of the rail 28.
[0040] By providing the rubber pad 26 , the friction between the rail 28 and the first mounting seat 14 and the second mounting seat 15 is increased, and the characteristics of the rubber pad 26 can be used to absorb vibration, thereby achieving the purpose of reducing impact force.
[0041] In the embodiment of the present invention, the receiver 24 further includes a display screen and a buzzer, and the display screen displays the direction and number of oncoming vehicles.
[0042] When the receiver 24 receives the signal from the transmitter 25, the display screen shows the direction and number of oncoming vehicles, which is convenient for the attendant to observe the upcoming train, and sends a rough alarm signal through the buzzer to prompt the attendant to close the crossing gate 10 in time to prevent social vehicles and pedestrians from entering the crossing.
[0043] Specifically, the receiver 24 also includes a signal indication circuit, which displays whether the current 4G signal and the working status of the sensor group are intact.
[0044] In the embodiment of the utility model, a solar panel is provided on the top of the transmitter 25, a battery is provided on the bottom of the transmitter 25, and the battery is buried deep under the frozen soil layer.

[0047] Specifically, the transmitter 25 also includes a single-chip microcomputer, a 4G module and a circuit. The transmitter 25 drives the 4G module to send data to the server. After receiving the data, the server uploads the data to the receiver 24, and the receiver 24 issues an alarm. The transmitter 25 uses 4G as a carrier for data communication. In places where the 4G signal is good, it is not affected by distance, thus avoiding the waste of funds and construction difficulties caused by long-distance radiating cables.
[0048] In the embodiment of the present utility model, the first sensor 22 and the third sensor 29 are respectively installed at a position where the rails of the up railway track are 5000 meters away from the highway level crossing and the rails of the down railway track are 5000 meters away from the highway level crossing.
[0049] The utility model realizes the purpose of long-distance alarm by respectively arranging the first sensor and the third sensor at a distance of 5000 meters between the rails of the upward railway track and the road level crossing and the rails of the downward railway track and the road level crossing, and combining the transmitter 25, the receiver 24 and the sensor group.
[0050] Implementation process: By firmly installing the fixture on the rail 28 and adjusting the sensor group to a suitable position, the sensor group can detect the trains coming and going. When the first sensor 22 and the third sensor 29 detect the arrival of a train, the signal is transmitted to the receiver 24. After receiving the signal, the receiver 24 sends an audible and visual alarm to remind the level crossing attendant that the train is about to pass through the crossing, and at the same time starts the gate not closed controller to remind the attendant to immediately close the crossing gate 10 and stop the highway 13 vehicles from passing through the crossing. When the receiver receives the signal that a train is about to pass through the crossing, the controller of the crossing gate 10 locks the gate opening controller. At this time, the attendant can only close the gate but cannot open it, even if there are multiple trains about to pass through the crossing. Only when all trains have completely passed through the level crossing for a period of time, the second sensor 23 and the fourth sensor 30 respectively send a train passing signal to release the locking of the crossing gate 10, and the attendant can smoothly open the gate and let the highway 13 vehicles pass, thereby avoiding collision accidents caused by opening the gate incorrectly.
