Description

Technical Field

[0001] The utility model relates to the technical field of railway crossings, and particularly relates to an intelligent alarm system for a railway level crossing. Background Art

[0002] A level crossing refers to a place where a railway and a road cross each other on the same plane. When a railway intersects with a road, when the road traffic volume is small or there is no condition to set up a grade separation, the road should be reasonably merged and then a level crossing should be set up. To reduce crossing accidents, for crossings where the designed speed of railway passenger trains reaches 140 km / h and 120 km / h, a person must be on duty to guard; for crossings where the designed speed of railway passenger trains is slightly lower, reaching 100 km / h and 80 km / h, but the average annual day-night converted traffic volume (in the fifth year after the crossing is put into operation) of the crossing is greater than 10,000 vehicles and 20,000 vehicles respectively, a person should also be on duty to guard.

[0003] CN108032880A discloses a manned railway crossing safety system, including two tracks, a first pole, a second pole, a third pole, a fourth pole, a control room, a magnetoresistive sensor and an LED display device. The magnetoresistive sensor arranged on the track accurately obtains the arrival time of the train and gives an early warning in advance, evacuates the pedestrians and vehicles at the crossing and closes its passage, lights up the LED display device for dynamic display and reminder. If a pedestrian or vehicle does not notice the LED reminder caption, the infrared sensor makes a distance judgment. Once it enters the safe distance range, the voice alarm is triggered again, and at the same time, the guard can arrive at the scene in time to check. However, there are still the following technical problems: if the guard is not on the scene, the accident cannot be prevented in time. Content of the Utility Model

[0004] The utility model aims to solve the technical problems existing in the prior art, and particularly innovatively provides an intelligent alarm system for a railway level crossing, which is applicable to manned crossings, can detect the standing post of the on-duty staff, send a stop signal to the train and the road before the train arrives at the crossing, completely prohibit passage, and prevent safety accidents from occurring.

[0005] To achieve the above object, the utility model provides an intelligent alarm system for railway level crossings, which includes traffic lights, an oncoming train signal acquisition unit and a departing train signal acquisition unit respectively used for detecting the arrival or departure of trains, and also includes a protection detection unit and a protection signal machine. The protection signal machine is arranged on the left side of the oncoming direction of the up-line section of the railway. The protection detection unit includes a gate position detector and a personnel standing guard detector. The gate position detector is used to detect whether the gates on both sides of the railway on the road are opened in place. The personnel standing guard detector is arranged at the duty room near the crossing. The duty room is also provided with a patrol control unit. The detection output end of the gate position detector is connected to the gate position signal input end of the patrol control unit. The detection output end of the personnel standing guard detector is connected to the standing guard signal input end of the patrol control unit. The detection output end of the oncoming train signal acquisition unit is connected to the oncoming train signal input end of the patrol control unit. The detection output end of the departing train signal acquisition unit is connected to the departing train signal input end of the patrol control unit. The road passage signal output end of the patrol control unit is connected to the signal input end of the traffic lights. The train passage signal output end of the patrol control unit is connected to the signal input end of the protection signal machine.

[0006] In the above solution: each of the oncoming train signal acquisition units is equipped with a front-end wireless transceiver unit, and the patrol control unit is equipped with a centralized control transceiver unit and is wirelessly connected to the centralized control transceiver unit through the front-end wireless transceiver unit. It can transmit data through wireless signals, improve the transmission efficiency, is easy to install, and does not require wiring.

[0007] In the above solution: both the oncoming train signal acquisition unit and the departing train signal acquisition unit include pressure sensors, and can detect whether a train is approaching or departing through the pressure sensors.

[0008] In the above solution: the protection signal machine and the traffic lights are respectively equipped with a protection signal machine self-check controller and a traffic light self-check controller. The feedback signal output end of the protection signal machine is connected to the signal input end of the protection signal machine self-check controller. The signal output end of the protection signal machine self-check controller is connected to the protection signal machine feedback input end of the patrol control unit. The feedback signal output end of the traffic lights is connected to the signal input end of the traffic light self-check controller. The signal output end of the traffic light self-check controller is connected to the traffic signal feedback input end of the patrol control unit. It can perform self-check and patrol through the protection signal machine self-check controller and the traffic light self-check controller to timely detect equipment failures and reduce potential safety hazards.

[0009] In the above solution: monitoring units are arranged on the roads on both sides of the railway and in the duty room, and the road conditions can be viewed through the monitoring units.

[0010] In the above solution: The railway has only a pair of tracks. The oncoming signal acquisition unit and the departing signal acquisition unit are both in two groups and are both arranged on the same side of the railway. The protection signal lights are also two and are respectively arranged on the left and right sides of the railway. When there is only a pair of tracks, arranging them on the same side can improve the installation efficiency.

[0011] In summary, the beneficial effects of the present utility model are as follows: It can pre - send a stop - passing signal to the traffic signal lights and the protection signal lights to prohibit the highway and the train from passing to ensure the occurrence of an accident. After the staff trigger the passing instruction at the personnel standing detector, the protection signal lights are driven by the inspection control unit to prompt the train to pass first. After the train departs, the traffic signal lights are driven by the inspection control unit to prompt pedestrians and cars to pass, ensuring traffic safety. The provided oncoming signal acquisition unit and departing signal acquisition unit can automatically detect the arrival or departure of the train, so as to automatically switch to highway passage through the inspection control unit. It can ensure that after the safety hazards are eliminated by the duty personnel before passing, which can not only ensure the presence of the duty personnel at the scene, but also improve safety.

[0015] The present utility model will be further described below through embodiments in conjunction with the drawings:

[0016] Embodiment 1

[0017] As Figures 1 to 2 shown, an intelligent alarm system for a railway level crossing includes traffic signal lights 9, an inspection control unit 7, an oncoming signal acquisition unit 1 and a departing signal acquisition unit 3 respectively used to detect the arrival or departure of a train.

And all pressure sensors are also installed through sensor brackets and are provided with sensor protective covers. The oncoming signal acquisition unit 1 is arranged on one side of the upstream section of the railway, and the departing signal acquisition unit 3 is arranged in the downstream section of the railway and is close to the highway. The railway in this embodiment has only a pair of tracks. The oncoming signal acquisition unit 1 and the departing signal acquisition unit 3 are both in two groups and as Figure 2As shown, they are all set on the same side of the railway. The detection output end of the oncoming train signal acquisition unit 1 is connected to the oncoming train signal input end of the inspection control unit 7, and the detection output end of the departing train signal acquisition unit 3 is connected to the departing train signal input end of the inspection control unit 7. The highway traffic signal output end of the inspection control unit 7 is connected to the signal input end of the traffic signal lamp 9. The models of the inspection control unit 7 in this embodiment include but are not limited to S7-300 or XRL-KZ01.

[0018] To improve the transmission efficiency and installation efficiency, each oncoming train signal acquisition unit 1 is equipped with a front-end wireless transceiver unit 2, and the inspection control unit 7 is equipped with a centralized control transceiver unit 4, and they are wirelessly connected through the front-end wireless transceiver unit 2 and the centralized control transceiver unit 4. Among them, the centralized control transceiver unit 4 includes a wireless signal receiver with the model XRL-A450-5W and a wireless signal transmitter with the model XRL-T910M. The front-end wireless transceiver unit 2 includes a wireless signal receiver with the model XRL-A450-5W, a wireless signal transmitter with the model XRL-T910M, and a road remote controller with the model XRL-4L(XRL-4L-A)4.

[0019] On the up section of the railway, a protective signal machine 8 is also set, and the protective signal machine 8 is set on the left side in the oncoming train direction. There are also two protective signal machines 8 respectively set on the left and right sides of the railway, and the train passing signal output end of the inspection control unit 7 is connected to the signal input end of the protective signal machine 8.

[0020] It also includes a protection detection unit, and the protection detection unit includes a gate in-place detector 5 and a personnel standing guard detector 6. The gate in-place detector 5 is used to detect whether the gates on both sides of the highway of the railway are opened in place. In this embodiment, the gate in-place detector 5 directly uses the in-place feedback detection element of the gate machine.

[0021] The personnel standing guard detector 6 is set at the duty room near the crossing. The personnel standing guard detector 6 in this embodiment is a card reader with the model R330M or XRL-DK01. The inspection control unit 7 is installed in the duty room. The detection output end of the gate in-place detector 5 is connected to the gate in-place signal input end of the inspection control unit 7, and the detection output end of the personnel standing guard detector 6 is connected to the standing guard signal input end of the inspection control unit 7.

[0022] The protective signal machine 8 and the traffic signal lamp 9 are respectively equipped with a protective signal machine self-checking controller of model XRL-3K and a traffic signal lamp self-checking controller of model XRL-4HL. The feedback signal output end of the protective signal machine 8 is connected to the signal input end of the protective signal machine self-checking controller, and the signal output end of the protective signal machine self-checking controller is connected to the protective signal machine feedback input end of the inspection control unit 7. The feedback signal output end of the traffic signal lamp 9 is connected to the signal input end of the traffic signal lamp self-checking controller, and the signal output end of the traffic signal lamp self-checking controller is connected to the traffic signal feedback input end of the inspection control unit 7. Monitoring units 10 are arranged on the roads on both sides of the railway and in the duty room.

[0023] When the oncoming train signal acquisition unit 1 detects an oncoming train, the inspection control unit 7 first drives the traffic signal lamp 9 and the protective signal machine 8 to display red lights simultaneously to prohibit trains, automobiles and pedestrians from passing. At this time, the duty staff checks whether the turnstile is in the closed state. If the turnstile is in the closed state, the duty staff swipes the card at the personnel standing detector 6, that is, the crossing protection is successful. If the turnstile is not in the closed state, the duty staff closes the turnstile. At this time, the inspection control unit 7 drives the red light of the protective signal machine 8 to go out, and the train can pass normally. When the departure signal acquisition unit 3 detects that the train has completely passed, the inspection control unit 7 drives the turnstile to open. After the turnstile position detector 5 detects that the turnstile is completely opened, the traffic signal lamp 9 automatically changes from red to yellow flashing, and vehicles and pedestrians on the road can pass.

[0024] When the oncoming train signal acquisition unit 1 detects an oncoming train, if the turnstile is not in the closed state, or the duty staff does not swipe the card at the personnel standing detector 6 within the specified time, it means that the crossing protection is judged to be inadequate and there is a safety hazard. At this time, the inspection control unit 7 drives the traffic signal lamp 9 and the protective signal machine 8 to display red lights, and neither the road nor the railway allows vehicles to pass. After the turnstile is closed and the standing detector 6 detects the card swiping information of the duty staff at the same time, it means that the danger is eliminated, the red light of the protective signal machine 8 goes out, and the train is released. After the train passes through the departure signal acquisition unit 3, the inspection control unit 7 drives the turnstile to open. When the turnstile is fully opened, the traffic signal lamp 9 automatically changes from red to yellow flashing, and vehicles and pedestrians on the road can pass.
