[0002] In recent years, with the rapid development of my country's railway transportation, the level of railway electrification has become higher and higher, and a fairly high level of automation has been achieved in many aspects such as train driving, parking, and maintenance. At the same time, as a major railway country, my country still has a large number of locomotives in use. Many of these vehicles are old models with low automation levels. When docking railway train carriages, it mainly relies on manual operation. The locomotive driver needs to stop the train carriages under the guidance of the guide based on experience. However, in the actual operation process, since the locomotive driver often relies on experience to judge the parking distance, at night or in an environment with low visibility, the locomotive driver's judgment of the parking distance will be affected, which increases the difficulty of operation and safety risks. In order to solve the above problems, the utility model proposes a locomotive approaching coupling alarm. Summary of the invention

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0018] like Figure 1-3The locomotive approach coupling alarm shown includes a microcontroller unit 105, a drive module 107, a parameter input module, a prompt output module, a laser ranging sensor 112, and a power module 106 electrically connected to the drive module 107 and the microcontroller unit 105. The microcontroller unit 105 is usually an MCU module with low cost and high reliability.

[0019] The prompt output module includes a red light 108, a green light 109, a display 110 and a buzzer 111, and the prompt output module is electrically connected to the micro control unit 105 through the driving module 107. The driving module 107 is a driver for the red light 108, the green light 109, the display 110 and the buzzer 111, and is controlled by the micro control unit 105. The driving module 107 can drive the red light to start, the green light to start, the display to display real-time parameters or the buzzer to alarm, and can also drive two or more units at the same time to meet the needs under different working conditions.

[0020] The parameter input module and the laser range finder sensor 112 are electrically connected to the microcontroller unit 105, and the parameter input module is used to input preset parameter instructions to the MCU to adjust the operating parameters of the MCU. The basic configurable options of the parameter input module include setting menu, distance +, distance -, confirmation settings, etc. Its specific morphological structure can adopt a button panel or a touch panel (touch screen). When a button panel is adopted, it includes physical buttons such as button + 104, button - 103, button confirmation 102, and button settings 101. When a touch screen is adopted, the display 110 of the general prompt output module and the parameter input module are the same touch screen.

[0021] The laser distance measuring sensor 112 of the utility model is installed on the front of the locomotive. The parameter input module and the prompt output module are both arranged on the control panel of the locomotive driver's cab, so as to facilitate the driver to perform quick operation and receive information, and realize quick human-computer interaction.

[0022] The working embodiment is as follows: when the laser ranging sensor measures that the distance between the locomotive head and the car to be docked is 110 meters, the buzzer reminds the locomotive driver: the distance is 110 meters at this time, please slow down and keep the speed below 17km / h, and the display shows the distance between the locomotive head and the car to be docked and the speed of the locomotive at this time; when the laser ranging sensor measures that the distance between the locomotive head and the car to be docked is 55 meters, the buzzer reminds the locomotive driver: the distance is 55 meters at this time, please slow down and keep the speed below 12km / h, and the display shows the distance between the locomotive head and the car to be docked. The distance between the locomotive and the car to be docked and the speed of the locomotive at this time; when the laser ranging sensor measures that the distance between the locomotive front and the car to be docked is 33 meters, the buzzer reminds the locomotive driver: the distance is 33 meters at this time, please slow down and keep the speed below 7km / h, and the display shows the distance between the locomotive front and the car to be docked and the speed of the locomotive at this time; when the laser ranging sensor measures that the distance between the locomotive front and the car to be docked is less than 15 meters, the green light in the cab goes out and the red light comes on, and the buzzer reminds the locomotive driver: the distance is less than 15 meters at this time, please stop immediately to dock the cars.

[0023] When the laser ranging sensor measures that the distance between the locomotive head and the car to be docked is less than 10 meters, the green light in the cab goes out and the red light comes on, and the buzzer reminds the locomotive driver: the distance is less than 10 meters at this time, please stop immediately to dock the cars.

[0024] The utility model uses the distance measured by the laser ranging sensor to remind the locomotive driver to slow down or stop, which is more accurate than the driver's judgment of the parking distance based on experience, especially at night or in low visibility conditions, greatly improving the efficiency of railway train docking.

[0025] When installing the laser distance sensor 112, since the laser distance sensor 112 is a linear detection, a flat, protruding surface on the carriage should be selected as the reference surface as much as possible to better improve the detection accuracy. Therefore, when installing the laser distance sensor 112, it is necessary to consider that the actual installation position after installation should have a debugging margin to better achieve universal adaptation to different types of carriages and locomotives.

[0026] To this end, the utility model also discloses a special adjustment bracket, such as Figure 2 and 3 As shown in the figure, the laser distance sensor 112 is installed on the front of the locomotive through an adjustment bracket, and the adjustment bracket includes a square frame 1, and the frame 1 is evenly distributed with a plurality of screw holes 2, and is installed on the front of the locomotive through screws. In order to meet the flexibility of installation, the screw holes 2 are preferably strip holes extending along the length direction of each side of the frame 1.

[0027] The inner edge of the frame 1 is also provided with an inner retaining edge 3 perpendicular to the frame 1 (that is, an L-shaped folded edge forms the inner retaining edge 3). In order to further improve the strength, reinforcing ribs 9 are provided at the inner retaining edges 3 at the four corners of the frame 1. The inner retaining edges 3 on the left and right sides are provided with mounting holes 4 extending along the length direction of the inner retaining edges 3, that is, the mounting holes 4 are strip holes, and their extending direction is as follows: Figure 2 and 3 The adjusting bracket also includes two mutually parallel mounting screws 5, both ends of which are inserted into the mounting hole 4, and both ends are adapted with tension nuts 6. The tension nuts 6 can be composed of two independent nuts, and washers and springs can be added between the two to further ensure the locking strength.

[0028] The specific installation form of the laser distance sensor 112 is as follows: Figure 2 As shown in the figure, the upper and lower sides of the housing of the laser ranging sensor 112 are provided with mounting sleeves 7 adapted to the mounting screw 5, and are passed through the mounting sleeves 7 on the mounting screw 5. The mounting screws 5 at both ends of the mounting sleeves 7 are provided with clamping nuts 8.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
