Description

Technical Field

[0001] The present application relates to the technical field of train positioning, and in particular to a train positioning method, a controller, a computer-readable storage medium, a processor, and a train positioning system. Background Art

[0002] Railway transportation is a relatively important mode of transportation today, enabling fast and efficient long-distance transportation. Railway train cars come in a variety of types, each with a different load capacity. Mixed trains are often encountered during loading or unloading. Therefore, if the train cannot be accurately positioned and the order and position of the cars cannot be accurately determined, loading or unloading operations will be more difficult and not conducive to management. For example, during coal loading, if the train cars cannot be accurately positioned, the spraying of antifreeze and dust suppressants during loading cannot be accurately controlled, resulting in waste of antifreeze and dust suppressants or untimely spraying.

[0003] The existing technology usually uses photoelectric sensors to determine the position and direction of travel of train cars. The specific solution is: photoelectric sensors are installed on the track. When the photoelectric sensors are blocked, it means that the car has entered the spraying area and spraying begins. If the photoelectric sensors are not blocked, it means that the gap between the two cars has entered the spraying area and spraying stops.

[0026] As introduced in the background technology, the prior art uses photoelectric sensors that are easily interfered with by the external environment to locate the train, resulting in inaccurate train positioning. In order to solve the problem of the prior art using photoelectric sensors that are easily interfered with by the external environment to locate the train, resulting in inaccurate train positioning, the embodiments of the present application provide a train positioning method, a controller, a computer-readable storage medium, a processor and a train positioning system.

It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0029] Figure 1 FIG. 1 is a flow chart of a train positioning method according to an embodiment of the present application. Figure 1 As shown, the method includes the following steps:

[0030] Step S201, the controller receives a plurality of the first digital signals from the analog-to-digital converter, wherein the first digital signals correspond one-to-one to the first electrical signals;

[0031] Specifically, a first digital signal represents that an axle passes through a first preset position.

[0032] It should be noted that if Figure 2 As shown, a train runs on a train track 10, the train includes a locomotive, the locomotive includes multiple axles, a first magnetic sensor 20 is set at a first preset position on the inner side of the train track 10, the first magnetic sensor 20 is communicatively connected to the analog-to-digital converter, when the axle passes directly above the first magnetic sensor 20, the first magnetic sensor 20 sends a first electrical signal to the analog-to-digital converter, the analog-to-digital converter is communicatively connected to the controller, the analog-to-digital converter is used to convert the first electrical signal into a first digital signal and send the first digital signal to the controller, and the train positioning method is applied to the controller.

[0033] It should also be noted that the axle is a magnetic object. When the axle passes through the first magnetic sensor, the magnetic field of the first magnetic sensor changes. The first magnetic sensor converts the magnetic field change into a first electrical signal and sends it to the analog-to-digital converter. The analog-to-digital converter is used to convert the first electrical signal into a first digital signal and send the first digital signal to the controller.

[0034] Step S202, the controller determines a first quantity based on all the first digital signals, where the first quantity is the quantity of the first digital signals;

[0035] Specifically, the number of the first digital signals represents the number of axles passing through the first preset position.

[0036] In order to achieve the positioning of the train, in an optional solution, the train further includes a plurality of carriages, each of which includes a preset number of axles. After step S202, the method further includes:

[0037] When the first number is greater than the second number, the controller determines The quotient of is the third quantity, determine The remainder is the fourth number, wherein Y is the first number, X1 is the second number, X2 is the preset number, the third number is the number of the carriages that have completely passed the first preset position at the current moment, the fourth number is the number of target axles that have completely passed the first preset position at the current moment, and the target axle is the axle of the carriage that has not completely passed the first preset position at the current moment.

[0038] In this embodiment, for example, the number of axles at the first preset position (the first number) is 15, the number of axles of the locomotive (the second number) is 6, and the number of axles of each carriage (the preset number) is 4. The quotient is 2 and the remainder is 1, that is, the number of cars that have completely passed the first preset position at the current moment (the third number) is 2, the car that has not completely passed the first preset position at the current moment is the third car, and the number of axles in the third car that have completely passed the first preset position at the current moment (the fourth number) is 1. At the current moment, the first preset position is between the first axle and the second axle of the third car.

[0039] In order to improve the accuracy of train positioning, in an optional solution, such as Figure 2 As shown, the third magnetic sensor 40 is arranged at a third preset position on the inner side of the above-mentioned train track 10, and the fourth magnetic sensor 50 is arranged at a fourth preset position on the inner side of the above-mentioned train track 10. The above-mentioned third preset position and the above-mentioned fourth preset position are located on different inner sides of the above-mentioned train track 10. The third direction is perpendicular to the length direction of the above-mentioned train track 10. The above-mentioned third direction starts from the above-mentioned third preset position and ends at the above-mentioned fourth preset position. The above-mentioned third magnetic sensor is communicatively connected with the above-mentioned analog-to-digital converter. When the above-mentioned axle passes directly above the above-mentioned third magnetic sensor, the above-mentioned third magnetic sensor sends a third electrical signal to the above-mentioned analog-to-digital converter. The above-mentioned analog-to-digital converter is used to convert the above-mentioned third electrical signal into a third digital signal and send the above-mentioned third digital signal to the above-mentioned controller. The above-mentioned fourth magnetic sensor is communicatively connected with the above-mentioned analog-to-digital converter. When the above-mentioned axle passes directly above the above-mentioned fourth magnetic sensor, the above-mentioned fourth magnetic sensor sends a fourth electrical signal to the above-mentioned analog-to-digital converter. The above-mentioned analog-to-digital converter is used to convert the above-mentioned fourth electrical signal into a fourth digital signal and send the above-mentioned fourth digital signal to the above-mentioned controller. Before the above-mentioned step S202, the above-mentioned method further includes:

[0040] The controller controls the analog-to-digital converter to detect whether the third electrical signal and the fourth electrical signal are received;

[0041] When the analog-to-digital converter receives the third electrical signal and the fourth electrical signal, the controller determines a result, where the result indicates that the train is passing through the first preset position.

[0042] In this embodiment, a third magnetic sensor and a fourth magnetic sensor are arranged on different inner sides of the train track. When the analog-to-digital converter receives the electrical signal from the third magnetic sensor and the electrical signal from the fourth magnetic sensor, it is determined that a train is indeed passing through the first preset position, eliminating the possibility of interference from other magnetic conductive materials. Then, the controller determines the number of axles passing through the first preset position and locates the train based on the number of axles at the first preset position, thereby improving the accuracy of train positioning.

[0043] In order to promptly eliminate interference from other magnetically conductive materials, in an optional solution, the controller is in communication with an alarm. After the controller controls the analog-to-digital converter to detect whether the third electrical signal and the fourth electrical signal are received, the method further includes:

[0044] The controller generates a first alarm message when the analog-to-digital converter receives the third electrical signal but does not receive the fourth electrical signal. The controller generates a second alarm message when the analog-to-digital converter receives the fourth electrical signal but does not receive the third electrical signal. The first alarm message is information indicating that the third magnetic sensor is abnormal, and the second alarm message is information indicating that the fourth magnetic sensor is abnormal.

[0045] In this embodiment, when the analog-to-digital converter receives the third electrical signal and does not receive the above-mentioned fourth electrical signal, it indicates that other magnetic materials may have passed through the third magnetic sensor. At this time, the alarm sounds an alarm to remind the staff to promptly remove the magnetic materials near the third magnetic sensor. When the analog-to-digital converter receives the fourth electrical signal and does not receive the above-mentioned third electrical signal, it indicates that other magnetic materials may have passed through the fourth magnetic sensor. At this time, the alarm sounds an alarm to remind the staff to promptly remove the magnetic materials near the fourth magnetic sensor.

[0046] In order to determine the direction of travel of the train, in an optional solution, such as Figure 2 As shown, the second magnetic sensor 30 is disposed at a second preset position on the inner side of the train track 10. The second preset position and the first preset position are located on the same inner side of the train track 10. The first direction is the same as the length direction of the train track 10. The first direction starts from the first preset position and ends at the second preset position. The second magnetic sensor 30 is communicatively connected to the analog-to-digital converter. When the axle passes directly above the second magnetic sensor, the second magnetic sensor sends a second electrical signal to the analog-to-digital converter. The analog-to-digital converter is used to convert the second electrical signal into a second digital signal and send the second digital signal to the controller. Before step S202, the method further includes:

[0047] The controller obtains a first time and a second time from the analog-to-digital converter, wherein the first time is the time when the analog-to-digital converter receives the first first electrical signal from the first magnetic sensor, and the second time is the time when the analog-to-digital converter receives the first second electrical signal from the second magnetic sensor;

[0048] When the first moment is less than the second moment, the controller determines that the running direction of the train is the first direction. When the first moment is greater than the second moment, the controller determines that the running direction of the train is the second direction. The second direction starts from the second preset position and ends at the first preset position.

[0049] In this embodiment, when the analog-to-digital converter first receives the first electrical signal from the first magnetic sensor and then receives the second electrical signal from the second magnetic sensor, the train's traveling direction is determined to be the first direction; when the analog-to-digital converter first receives the second electrical signal from the second magnetic sensor and then receives the first electrical signal from the first magnetic sensor, the train's traveling direction is determined to be the second direction.

[0050] In order to determine the running speed of the train, after the controller obtains the first time and the second time from the analog-to-digital converter, the method further includes:

[0051] The controller calculates the absolute value of the difference between the first moment and the second moment to obtain the running time;

[0052] The controller calculates the ratio of the running distance to the running time to obtain the running speed, wherein the running distance is the distance between the first preset position and the second preset position, and the running speed is the running speed of the train.

[0053] In this embodiment, for example, the distance between the first preset position and the second preset position is L, and the time difference between the moment when the analog-to-digital converter receives the first electrical signal from the first magnetic sensor and the moment when the analog-to-digital converter receives the second electrical signal from the second magnetic sensor is T. According to the formula V=L / T, the running speed V is obtained, that is, the traveling speed of the train is obtained.

[0054] In step S203, the controller determines that the locomotive has not completely traveled past the first preset position when the first number is less than or equal to a second number, where the second number is the number of the axles of the locomotive.

[0055] Specifically, when the number of axles passing through the first preset position is less than or equal to the number of axles of the locomotive, it is determined that the locomotive has not completely passed the first preset position. For example, the number of axles of the locomotive (first number) is 6, and the number of axles passing through the first preset position (second number) is 4. At this time, the first preset position is between the 4th and 5th axles of the locomotive. The number of axles of the locomotive (first number) is 6, and the number of axles passing through the first preset position (second number) is 6. At this time, it is determined that the first preset position is at the connection position between the locomotive and the first carriage.

[0056] It should be noted that in this application, the connection point between the locomotive and the first carriage belongs to the locomotive.

[0057] Through the above embodiment, when an axle passes through the first magnetic sensor, the magnetic field of the first magnetic sensor changes. The first magnetic sensor converts the magnetic field change into a first electrical signal and sends it to the analog-to-digital converter. The analog-to-digital converter converts the first electrical signal into a first digital signal and sends the first digital signal to the controller. The controller determines that the number of first digital signals is the number of axles passing through the first preset position. When the number of axles passing through the first preset position is less than or equal to the number of axles of the locomotive, the controller determines that the locomotive has not completely passed the first preset position, thereby achieving the positioning of the train. Compared with the prior art that uses photoelectric sensors that are easily interfered with by the external environment to locate the train, resulting in inaccurate train positioning, the first magnetic sensor of the present application does not come into direct contact with the axle, and uses an active magnetic field, is not affected by the external environment, is stable and reliable when used, and can achieve accurate positioning of the train. This method solves the problem of the prior art that uses photoelectric sensors that are easily interfered with by the external environment to locate the train, resulting in inaccurate train positioning.

The first direction starts from the first preset position and ends at the second preset position. The second magnetic sensor 30 is communicatively connected to the analog-to-digital converter. When the axle passes directly above the second magnetic sensor, the second magnetic sensor sends a second electrical signal to the analog-to-digital converter.

[0139] 1) The train positioning method of the present application, a train running on a train track, the train including a locomotive, the locomotive including multiple axles, a first magnetic sensor arranged at a first preset position on the inner side of the train track, the first magnetic sensor being communicatively connected to an analog-to-digital converter, when the axle passes directly above the first magnetic sensor, the first magnetic sensor sending a first electrical signal to the analog-to-digital converter, the analog-to-digital converter being communicatively connected to a controller, the analog-to-digital converter being used to convert the first electrical signal into a first digital signal and sending the first digital signal to the controller, the train positioning method being applied to the controller, the method comprising: the controller receiving multiple first digital signals from the analog-to-digital converter, the first digital signals corresponding one-to-one to the first electrical signals; the controller determining a first number based on all the first digital signals, the first number being the number of the first digital signals; the controller determining that the locomotive has not completely passed the first preset position when the first number is less than or equal to a second number, the second number being the number of the axles of the locomotive. When an axle passes through the first magnetic sensor, the magnetic field of the first magnetic sensor changes. The first magnetic sensor converts the magnetic field change into a first electrical signal and sends it to the analog-to-digital converter. The analog-to-digital converter converts the first electrical signal into a first digital signal and sends the first digital signal to the controller. The controller determines that the number of first digital signals is the number of axles passing through the first preset position. When the number of axles passing through the first preset position is less than or equal to the number of axles of the locomotive, the controller determines that the locomotive has not completely passed the first preset position, thereby achieving the positioning of the train. Compared with the prior art that uses photoelectric sensors that are easily interfered with by the external environment to position the train, resulting in inaccurate train positioning, the first magnetic sensor of the present application will not have direct contact with the axle, and uses an active magnetic field, which is not affected by the external environment. It is stable and reliable when used, and can achieve accurate positioning of the train. This method solves the problem of the prior art that uses photoelectric sensors that are easily interfered with by the external environment to position the train, resulting in inaccurate train positioning.

When an axle passes through the first magnetic sensor, the magnetic field of the first magnetic sensor changes. The first magnetic sensor converts the magnetic field change into a first electrical signal and sends it to the analog-to-digital converter. The analog-to-digital converter converts the first electrical signal into a first digital signal and sends the first digital signal to the controller. The controller determines that the number of first digital signals is the number of axles passing through the first preset position. When the number of axles passing through the first preset position is less than or equal to the number of axles of the locomotive, the controller determines that the locomotive has not completely passed the first preset position, thereby achieving the positioning of the train. Compared with the prior art that uses photoelectric sensors that are easily interfered with by the external environment to position the train, resulting in inaccurate train positioning, the first magnetic sensor of the present application will not have direct contact with the axle, and uses an active magnetic field, which is not affected by the external environment. It is stable and reliable when used, and can achieve accurate positioning of the train. The controller solves the problem of the prior art that uses photoelectric sensors that are easily interfered with by the external environment to position the train, resulting in inaccurate train positioning.
