Description

Technical Field

[0001] The utility model relates to an early relief detection device, belonging to the field of train detection. Background Art

[0002] Due to the limited transport capacity of railway lines, some trains have to give way at stations, usually freight trains give way to passenger trains, and slow trains give way to high-speed trains. Generally, after the passing train has completely entered a siding through the main line, the waiting train parked on the other siding will start to move. After starting, the train needs to ease, which makes the tail of the train extend and lengthen. The time required for ease is related to parameters such as locomotive model, decompression, and number of trains. The average ease time is more than 5 minutes.

[0003] When the passing train is running on the main line, the waiting train parked on the other side line cannot be relieved in advance because: if the passing train is running on the main line, the waiting train parked on the other side line will start to move at this time. After starting, the waiting train will be relieved first, making the tail of the train extend longer, such as Figure 1 As shown, if the extended length of the waiting train exceeds the insulating joint or invades the insulating joint, the track circuit will be turned on and the interlocking turnout system will immediately close the section, affecting the normal traffic order; if the extended length of the train exceeds the warning mark on the main line and the overtaking train has arrived at this time, it may cause the overtaking train to collide with the rear of the extended waiting train, causing a traffic accident.

[0004] All trains are parked on the siding, with the front of the train aligned with the stop sign. Although the trains are parked at the stop sign, the length of each train is different, resulting in an unstable position of the rear of the train. Currently, no matter how long or short the train is, the waiting train cannot be relieved in advance, reducing the efficiency of train dispatching. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0035] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0036] Example:

[0037] Combination Figures 2 to 5 This embodiment is described, a train early relief detection device, the relief detection device comprises a detection device 10, a geomagnetic device fixing part 14, a controller, a communication device, a No. 1 indicator light strip 5 and a No. 2 indicator light strip 6;

[0038] The geomagnetic device fixing member 14 is arranged on the railway sleeper 15 inside the railway insulation joint 12;

[0039] The geomagnetic equipment fixing member 14 comprises two U-shaped frames 1, four connecting ears 4, a connecting rod 2 and a hoop 3;

[0040] Each U-shaped frame 1 is connected to a connecting ear 4 at both ends, and each U-shaped frame 1 and the two connecting ears 4 are an integral structure.

[0041] Two U-shaped frames 1 are buckled on the upper and lower sides of the railway sleepers, and screws are passed through the connecting ears 4 to fix the two U-shaped frames 1 together. One end of the connecting rod 2 is connected to the side wall of the bottom U-shaped frame 1, and the other end of the connecting rod 2 is connected to the clamp 3. The detection device 10 is set in the clamp; and the distance between the detection device 10 and the railway insulation joint 12 is a set distance;

[0042] The detection device 10 is used to detect whether a reflected signal from the bottom of the train 17 is detected after the train 17 stops, and send the reflected signal to the controller through the communication device.

[0043] The controller is used to control the No. 1 indicator light strip 5 to light up when the reflected signal is received, prompting the train 17 not to ease in advance; when the reflected signal is not received, the controller controls the No. 2 indicator light strip 6 to light up, prompting the train 17 to ease in advance.

[0044] Specifically, because the train runs in both directions, it may be Figure 5 The direction of travel may also be Figure 5 Running in the opposite direction, if Figure 5 If the train travels in the opposite direction of its running direction, it is necessary to set a detection device on the sleepers traveling in the opposite direction. Therefore, in this embodiment, a geomagnetic device fixing part, a detection device, a relief detection device, a No. 1 indicator light belt and a No. 2 indicator light belt can be set in two-way directions.

[0046] like Figure 5 As shown, when the front of the train is aligned with the stop sign and stops, the detection device 10 of this embodiment is placed at a set distance from the railway insulation joint 12. When the train stops, the train does not pass over the detection device 10, indicating that the train can be relieved in advance. Therefore, the controller controls the No. 2 indicator light strip 6 to light up, and the No. 2 indicator light strip 6 displays "1". When the train driver or staff sees "1", they perform the early relief operation, and the train will not cross the insulation joint 12 after relief. When the train stops and passes over the detection device 10, the controller controls the No. 1 indicator light strip 5 to light up, and the No. 1 indicator light strip 5 displays "1". When the train driver or staff sees "1", the early relief operation is prohibited.

[0047] The structure included in this embodiment is further defined below:

[0048] The mitigation detection device further comprises an indication device 13,

[0049] The indicating device 13 is arranged on the platform; the indicating device 13 comprises a box 8, a bracket 9, a solar cell panel 7 and a battery;

[0050] The box body 8 is supported on a bracket 9, and the solar panel 7 is arranged on the top of the box body 8;

[0051] The controller and the battery are both arranged in the box 8, the indicator light strip 5 and the indicator light strip 6 are embedded in the surface of the box 8 in a cross position, the solar panel 7 supplies power to the battery, and the battery supplies power to the controller, the indicator light strip 5 and the indicator light strip 6.

[0052] Specifically, the indicating device 13 is installed in Figure 5 The platform shown is convenient for the train driver to check the displays of indicator light strip No. 1 5 and indicator light strip No. 2 6. When the indicator light strip No. 1 5 displays "1", the early relief operation is not performed; when the indicator light strip No. 2 6 displays "1", the early relief operation is performed.

[0053] The set distance is further limited below: the set distance is 10m.

[0054] Specifically, 10 meters is the train relief length.

[0055] The following further describes the equipment included in this embodiment:

[0056] The apparatus further comprises a positioning device,

[0057] The positioning device 11 is arranged at the rear of the train and is used to detect the position of the rear of the train 17 after the train is relieved in advance.

[0058] Specifically, when the train is relieved in advance, the position of the rear of the train is detected and transmitted to the locomotive terminal for display to determine the position reached by the rear of the train after the early relief.

[0059] The preferred modules of the positioning device are introduced below: Positioning device 1 is a Beidou positioning module.

[0060] The preferred modules of the communication equipment are introduced below: the communication equipment is a 4G communication equipment.

[0061] Specifically, the model of the 4G communication equipment is AIR724UG.

[0062] The following introduces the controller model: the controller model is STM32.

[0065] The detection device 10 includes a geomagnetic sensor and a millimeter wave radar;

[0066] The geomagnetic sensor is used to detect the magnetic field disturbance signal generated when the train 17 arrives and send it to the millimeter wave radar;

[0067] The millimeter wave radar is used to send a radar signal to the bottom of the train 17 after receiving the magnetic field disturbance signal. If no reflected signal from the bottom of the train 17 is received, it is determined that there is no train 17 on the top of the millimeter wave radar. If a reflected signal from the bottom of the train 17 is received, it is determined that there is a train 17 on the top of the millimeter wave radar.

[0068] Specifically, when a train passes, it will cause magnetic field disturbance. The geomagnetic sensor is used to detect the magnetic field disturbance. When the magnetic field disturbance occurs, it is determined that a train has arrived. The magnetic field disturbance is used as a trigger signal for the millimeter-wave radar to trigger the millimeter-wave radar to transmit a radar signal. If there is a train, the radar signal will be transmitted to the bottom of the train, and the bottom of the train will reflect the signal back. If there is no train, the bottom of the train will not reflect the signal back. Based on whether the reflected signal can be received, it is determined whether the train is pressing on the detection device, thereby determining whether it can be alleviated. The detection distance of the millimeter-wave radar is 20-40cm.
