Description

Technical Field

[0001] The present application relates to the field of ocean transportation, and in particular to an early warning method, device, equipment, medium, and product for ocean transportation of new energy vehicles. Background Art

[0002] With the development of the new energy electric vehicle market and the increase in international automobile trade, there is a growing demand for ocean transportation of various new energy vehicles. However, the large battery packs in new energy vehicles have a low probability of spontaneous combustion and other failure scenarios. Therefore, during international transportation (including but not limited to shipping), some new energy vehicles may experience thermal failure, namely spontaneous combustion.

[0003] Current methods of monitoring thermal failure during transportation are relatively traditional and cannot detect thermal failure in its early stages. For example, traditional smoke alarms, once triggered, actually indicate that the system has entered a combustion state, and may even pose a risk of fire to the entire ship or warehouse. Human intervention is difficult, resulting in huge property losses and life-threatening dangers. Summary of the Invention

[0004] In order to monitor abnormal conditions in the early stages of vehicle thermal failure and locate abnormal vehicles in a timely manner so as to arrange for staff to go to the cabin for inspection, the first aspect of the present application proposes an early warning method for ocean transportation of new energy vehicles, which is used in a cabin equipped with early warning terminals, wherein the early warning terminals are arranged in a matrix form.

[0005] The method includes the following steps: obtaining location information of multiple early warning terminals that emit abnormal signals, the location information including the floor number of the early warning terminal and the coordinates of the early warning terminal on the floor; for the early warning terminals with the same floor number, calculating the distance between the early warning terminals that emit abnormal signals, and determining the maximum distance between the first terminal and the second terminal that are farthest apart; when the maximum distance is greater than a threshold, based on a preset early warning area setting, determining multiple early warning areas of the same size and shape in the total area with the line connecting the first terminal and the second terminal as the diagonal; calculating the average value of the abnormal signals emitted by all the early warning terminals in each early warning area, and issuing an alarm at the midpoint of the early warning area with the largest average value.

[0006] Optionally, the warning area setting includes: the warning area is a square, and the threshold is the diagonal length of the warning area.

[0007] Optionally, the setting of the preset warning area includes determining a plurality of warning areas of the same size and shape in a total area with a line connecting the first terminal and the second terminal as a diagonal line, including:

[0008] Starting from the position of the first terminal or the second terminal, the warning area is determined end to end along the diagonal line of the warning area toward the second terminal or the first terminal;

[0009] When the last warning area exceeds the total area, the position of the second terminal or the first terminal is used as a starting point and the last warning area is re-determined along the diagonal line of the warning area toward the first terminal or the second terminal.

[0010] Optionally, when there is an overlapping area between two adjacent warning areas, average values ​​of abnormal signals of the overlapping area, a first area of ​​one warning area excluding the overlapping area, and a second area of ​​the other warning area excluding the overlapping area are calculated respectively, and judgment is performed:

[0011] When the average value of the abnormal signal in the overlapping area is the largest, a new warning area is determined with the position where the abnormal signal is the largest as the center;

[0012] When the average value of the abnormal signals in the overlapping area is greater than the average value of the abnormal signals in one of the first area and the second area, and less than the average value of the abnormal signals in the other of the first area and the second area, a new warning area is determined with the position where the abnormal signal is the largest as the center;

[0013] When the average value of the abnormal signal in the overlapping area is the smallest, no processing is performed.

[0014] By determining a new warning area centered on the new position based on the average value of abnormal signals in overlapping areas, the scope of the area where abnormal conditions may exist can be further narrowed.

[0015] Optionally, the warning area is a square area of ​​5m×5m.

[0016] Optionally, 9 warning terminals are set in each warning area.

[0017] Optionally, the maximum distance is determined according to the Pythagorean theorem based on the coordinates of the first terminal and the second terminal.

[0018] A second aspect of the present application provides an early warning device for ocean transportation of new energy vehicles, which is used in a cabin equipped with early warning terminals, wherein the early warning terminals are arranged in a matrix form and include:

[0019] a terminal positioning unit, configured to obtain location information of the plurality of warning terminals that send abnormal signals, the location information including the floor number of the warning terminal and the coordinates of the warning terminal on the floor;

[0020] a distance determining unit, configured to calculate, for the warning terminals on the same floor, the distances between the warning terminals that send abnormal signals, and determine the maximum distance between the first terminal and the second terminal that are the farthest apart;

[0022] The abnormality alarm unit is used to calculate the average value of the abnormality signals sent by all the warning terminals in each warning area, and to issue an alarm at the midpoint of the warning area where the average value is the largest.

[0023] A third aspect of the present application provides an electronic device, comprising a memory storing computer-executable instructions and a processor; when the instructions are executed by the processor, the device implements the method according to any one of the foregoing items.

[0024] A fourth aspect of the present application proposes a computer-readable medium, which stores one or more programs. The one or more programs can be executed by one or more processors to implement any of the methods described above.

[0025] A fifth aspect of the present application provides a computer program product, comprising a computer program, which implements any of the aforementioned methods when executed by a processor.

[0026] This application first screens out several key early warning terminals through the three-dimensional coordinates of each early warning terminal, and further determines one or more early warning areas through the key early warning terminals, thereby timely reducing the area where abnormal vehicles may exist to as small as possible in the early stage when abnormal situations may occur, greatly improving the efficiency of staff in searching for the location of abnormal vehicles and ensuring the safety of new energy vehicles during ocean transportation.

[0038] In order to make the above-mentioned purposes, features and advantages of this application more obvious and easy to understand, the early warning method for ocean transportation of new energy vehicles proposed in this application is further explained in detail below with reference to the accompanying drawings and specific implementation methods.

[0039] Figure 1 Flowchart of the early warning method for ocean transportation of new energy vehicles.

[0040] In step 101, the location information of multiple early warning terminals that send abnormal signals is obtained. The location information includes the floor number of the early warning terminal and the coordinates of the early warning terminal on the floor. Figure 2(a) is a schematic diagram of the distribution of early warning terminals on different floors in the cabin. Each cabin floor includes multiple neatly arranged early warning terminals 21. Figures 2(b) and 2(c) are schematic diagrams of the possible layouts of early warning terminals on each cabin floor (each black dot represents an early warning terminal). Figure 2(b) is an example of a dense matrix arrangement, and Figure 2(c) is an example of a sparse matrix arrangement. The location information can be represented in the form of coordinates. For example, based on the dense arrangement shown in Figure 2(b), the location information of the early warning terminal is represented as coordinates (x, y, z). Where z represents the floor number of the early warning terminal, x represents the horizontal coordinate position of the early warning terminal in the corresponding floor, and y represents the vertical coordinate position of the early warning terminal in the corresponding floor. Those skilled in the art will appreciate that the maximum values ​​of the horizontal and vertical coordinates in Figures 2(b) and 2(c) are merely examples and depend on the size of the area within the cabin where the new energy vehicle is located. Furthermore, the aforementioned location information is merely exemplary; other coordinate formats, or other forms other than coordinates, may be used to represent location information.

[0041] In step 102, for the early warning terminals with the same number of floors, the distance between the early warning terminals that send abnormal signals is calculated, and the maximum distance between the first terminal and the second terminal that is farthest away is determined. Since abnormalities may occur in vehicles in multiple floors at the same time, it is necessary to first divide the early warning terminals according to the number of floors to narrow the inspection scope after the alarm. When the location information of the vehicle is in the form of coordinates, the distance between the early warning terminals can be calculated based on the horizontal and vertical coordinates of the vehicle according to the Pythagorean theorem. For example, the coordinates of the first terminal and the second terminal located in the z1 floor are (x1, y1) and (x2, y2) in the z1 floor respectively, then the maximum distance d can be determined according to the following formula: After the early warning terminals are grouped according to the number of floors they are on, a preliminary area where abnormal vehicles may exist can be determined by determining the two early warning terminals that send abnormal signals that are farthest apart in each floor.

[0042] In step 103, when the maximum distance is greater than the threshold, based on the preset warning area setting, multiple warning areas of the same size and shape are determined in the total area with the line connecting the first terminal and the second terminal as the diagonal. Generally, based on the shape, size, parking position, space, etc. of the vehicle, the warning area setting may include: setting the warning area to a square, preferably a square, with the length of the square diagonal being the threshold; each warning area includes 9 warning terminals arranged in a 3*3 format. Figure 3As shown, the warning area is set as a 5m×5m square area, with nine warning terminals installed in each warning area, resulting in a threshold of approximately 7.07m. In this warning area setting, each warning area is guaranteed to cover the range of one vehicle. It is understood that other reasonable warning area settings are also possible.

[0043] Specifically, the warning area can be determined in the total area according to the following method: first, starting from the position of the first terminal or the second terminal, the warning areas are determined end to end along the diagonal of the warning area toward the direction of the second terminal or the first terminal; then, when the last warning area exceeds the total area, the position of the second terminal or the first terminal is used as the starting point, and the last warning area is re-determined along the diagonal of the warning area toward the direction of the first terminal or the second terminal.

[0044] In one example, when the coordinates of the first terminal are (1, 1) and the coordinates of the second terminal are (4, 4), the total area is ((1, 1), (4, 4)). If the above-mentioned warning area setting including 9 warning terminals is used, then with the position of the first terminal as the starting point and the position of the second terminal as the end point, the first warning area determined is ((1, 1), (3, 3)). At this time, if the second warning area is set up along the diagonal line, the remaining area ((3, 3), (4, 4)) will either not constitute a warning area or exceed the total area range. Therefore, when determining the last warning area, it is necessary to determine it with a different starting point and in the opposite direction from the previous one, that is, the position of the second terminal is used as the starting point and the position of the first terminal is used as the end point direction, so that the final second warning area is ((2, 2), (4, 4)). Figure 4(a) shows the total area and a warning area P including 9 warning terminals, and Figure 4(b) shows the total area and another warning area Q including 9 warning terminals.

[0045] It can be seen that there is an overlapping area between the adjacent warning areas P and Q. For ease of explanation, the portion of warning area P that does not include the overlapping area is called the first area, and the portion of warning area Q that does not include the overlapping area is called the second area, as shown in Figure 4(c). Then, the average value of the abnormal signals emitted by the warning terminals included in the overlapping area, the first area, and the second area is calculated respectively, and the following judgment is made:

[0046] When the average value of the abnormal signal in the overlapping area is the largest, a new warning area is determined, centered on the location with the largest abnormal signal. When the abnormal signal in the overlapping area is the largest, it indicates that the probability of an abnormal vehicle in the overlapping area is the highest among the three areas. Therefore, warning areas P and Q can be merged, with the location with the largest abnormal signal in the overlapping area serving as the center of the merged new warning area. For example, if the abnormal signal at location (2, 3) is the largest, a new warning area M ((2, 2), (4, 4)) is constructed, centered on (2, 3), as shown in Figure 4(d).

[0047] When the average value of the abnormal signal in the overlapping area is greater than the average value of the abnormal signal in one of the first area and the second area, and is less than the average value of the abnormal signal in the other area of ​​the first area and the second area, a new early warning area is determined with the position of the largest abnormal signal as the center. In other words, if the comparison result of the average values ​​of the abnormal signals in the first area, the overlapping area, and the second area is a gradient change form of lowest, lower, high, or high, lower, lowest, it can be considered that this is caused by the value of the abnormal signal gradually decreasing outward at a higher position. Therefore, the new early warning area can be determined with the position of the largest abnormal signal as the center. It can also be said that the original early warning area P and early warning area Q are merged into a new early warning area with the position of the largest abnormal signal as the center.

[0048] When the average value of the abnormal signals in the overlapping area is the smallest, no processing is performed. When the average value of the abnormal signals in the overlapping area is the smallest, it means that the probability of an abnormal vehicle existing between the first area and the second area is extremely small, so there is no need to merge the warning area P and the warning area Q.

[0049] In step 104, the average value of the abnormal signals emitted by all warning terminals in each warning zone is calculated, and an alarm is issued at the midpoint of the warning zone with the largest average value. The warning zone with the largest average value is the area with the highest probability of an abnormal vehicle appearing. Issuing an alarm at the midpoint of this warning zone allows staff to most efficiently determine the actual location of the abnormal vehicle.

[0050] Another aspect of the present application provides an early warning device 500 for ocean transportation of new energy vehicles, such as Figure 5 As shown, a cabin equipped with early warning terminals, wherein the early warning terminals are arranged in a matrix form, comprises:

[0051] The terminal positioning unit 501 is used to obtain the location information of multiple warning terminals that send abnormal signals. The location information includes the floor number of the warning terminal and the coordinates of the warning terminal on the floor.

[0052] The distance determining unit 502 is configured to calculate the distances between the warning terminals that send abnormal signals for the same number of warning terminals, and determine the maximum distance between the first terminal and the second terminal that are the farthest apart;

[0054] The abnormality alarm unit 504 is used to calculate the average value of abnormality signals sent by all warning terminals in each warning area, and issue an alarm at the midpoint of the warning area with the largest average value.
