[0032] In this embodiment, a matching method for a tractor and a trailer running on a mobile terminal, a computer terminal, or a similar computing device is provided. 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 the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than here.

[0033] Figure 2 is a schematic flowchart of a matching method for a tractor and a trailer provided according to an embodiment of the present application. This method is applied to a processing platform of a commercial vehicle system. The above-mentioned commercial vehicle system further includes a plurality of tractors, a plurality of trailers, a plurality of temperature and pressure sensors, and a plurality of receivers. One of the above-mentioned tractors is connected to one of the above-mentioned trailers. A temperature and pressure sensor is respectively installed on the rim of each tire of the above-mentioned tractor, and a temperature and pressure sensor is respectively installed on the rim of each tire of the above-mentioned trailer. A receiver is respectively installed on each of the above-mentioned tractors. A receiver communicates with a temperature and pressure sensor and the above-mentioned processing platform respectively. The temperature and pressure sensor includes a temperature sensor and a pressure sensor. The sensor is installed on the rim inside each tire of the tractor and the trailer by binding. The receiver is installed on the transverse axis of the tractor, and then a display is installed inside the cab. The display is powered on through the power supply inside the vehicle. The temperature and pressure sensor is a temperature sensor and a pressure sensor, such asFigure 2 As shown in Figure 2 , the method includes the following steps:

[0034] Step S201: Receive the temperature and pressure sensor number group sent by the target receiver. The temperature and pressure sensor number group includes multiple temperature and pressure sensor numbers, and the target receiver is one of all the receivers;

[0035] Specifically, for example, after the receiver receives four temperature and pressure sensor numbers (i.e., A, B, C, D), it will screen the received temperature and pressure sensor number group. The temperature and pressure sensors inside the tire send signals every 10s. The receiver receives the disordered temperature and pressure sensor IDs (ID means number) within a certain range. When the upload times of the same temperature and pressure sensor ID reach 10 times, the receiver will determine that the temperature and pressure sensor ID is valid. Then, these valid and disordered temperature and pressure sensor IDs are packed into a temperature and pressure sensor number group and sent to the display. At this time, because the temperature and pressure sensor IDs are disordered, the temperature and pressure data cannot be displayed on the screen of the display. The display will take the display ID and all the received sensor IDs as a whole and transmit them to the data receiving server through the Internet of Things platform;

[0036] Step S202: Extract the first part of the temperature and pressure sensor numbers from all the temperature and pressure sensor numbers in the temperature and pressure sensor number group. The first part of the temperature and pressure sensor numbers forms the first sensor number group, and extract the second part of the temperature and pressure sensor numbers from all the temperature and pressure sensor numbers in the temperature and pressure sensor number group. The second part of the temperature and pressure sensor numbers forms the second sensor number group. The first sensor number group includes the temperature and pressure sensor numbers in the temperature and pressure sensor number group that belong to the tractor, and the second sensor number group includes the temperature and pressure sensor numbers in the temperature and pressure sensor number group that belong to the trailer;

[0037] Specifically, for example, there are ten temperature and pressure sensor numbers, and five of them are the temperature and pressure sensor numbers that belong to the tractor. Then, these five are extracted to form the first sensor number group, and the other five temperature and pressure sensor numbers that belong to the trailer are extracted to form the second sensor number group for subsequent matching work;

[0038] The database of the processing platform stores a first mapping relationship and a second mapping relationship. Step S202 includes the following steps (that is, extract the first part of the temperature and pressure sensor numbers from all the temperature and pressure sensor numbers in the temperature and pressure sensor number group. The first part of the temperature and pressure sensor numbers forms the first sensor number group, and extract the second part of the temperature and pressure sensor numbers from all the temperature and pressure sensor numbers in the temperature and pressure sensor number group. The second part of the temperature and pressure sensor numbers forms the second sensor number group, including the following steps):

[0039] Step S2021: Determine the above-mentioned first part of temperature and pressure sensor numbers according to the above-mentioned first mapping relationship and all the above-mentioned temperature and pressure sensor numbers in the above-mentioned temperature and pressure sensor number group. The above-mentioned first mapping relationship is used to represent the mapping relationship between the tire numbers of the tractor and the above-mentioned temperature and pressure sensor numbers.

[0040] Specifically, according to the first mapping relationship, it is convenient to find the above-mentioned temperature and pressure sensor numbers belonging to the trailer in the temperature and pressure sensor number group.

[0041] Step S2022: Determine the above-mentioned second part of temperature and pressure sensor numbers according to the above-mentioned second mapping relationship and all the above-mentioned temperature and pressure sensor numbers in the above-mentioned temperature and pressure sensor number group. The above-mentioned second mapping relationship is used to represent the mapping relationship between the tire numbers of the trailer and the above-mentioned temperature and pressure sensor numbers.

[0042] Specifically, according to the second mapping relationship, it is convenient to find the above-mentioned temperature and pressure sensor numbers belonging to the trailer in the temperature and pressure sensor number group.

[0043] Step S203: Determine the number of the target tractor corresponding to the above-mentioned target receiver according to all the above-mentioned temperature and pressure sensor numbers in the above-mentioned first sensor number group. The above-mentioned target tractor is one of all the above-mentioned tractors.

[0044] Specifically, for example, the temperature and pressure sensor numbers in the first sensor number group are A, B, C, D, and E respectively, and A, B, and C belong to the first tractor, and D and E belong to the second tractor, for the purpose of classification.

[0045] Step S203 includes the following steps (that is, determining the number of the target tractor corresponding to the above-mentioned target receiver according to all the above-mentioned temperature and pressure sensor numbers in the above-mentioned first sensor number group includes the following steps):

[0046] Step S2031: Extract multiple first target temperature and pressure sensor number groups from all the above-mentioned temperature and pressure sensor numbers in the above-mentioned first sensor number group. Each of the above-mentioned first target temperature and pressure sensor number groups includes at least one of the above-mentioned temperature and pressure sensor numbers in the above-mentioned first sensor number group. The above-mentioned temperature and pressure sensor numbers in the above-mentioned first target temperature and pressure sensor number group correspond to the numbers of the tractors.

[0047] Specifically, for example, the temperature and pressure sensor numbers in the first sensor number group are A, B, C, D, and E respectively, and A, B, and C belong to the first tractor, and D and E belong to the second tractor, for the purpose of classification.

[0048] Step S2032: Use the number of the tractor corresponding to the first target temperature and pressure sensor number with the largest quantity among the above-mentioned temperature and pressure sensor numbers as the number of the target tractor.

[0049] Specifically, since the number of temperature and pressure sensor numbers of the first tractor is greater than that of the second tractor, it is considered that the receiver is the receiver of the first tractor.

[0050] Step S204: Determine the number of the target trailer according to all the above-mentioned temperature and pressure sensor numbers in the second sensor number group and the number of the target tractor. The number of the target trailer is the number of the trailer connected to the tractor corresponding to the number of the tractor, so as to match the tractor corresponding to the target receiver with the target trailer.

[0051] Specifically, for example, if the temperature and pressure sensor numbers in the second sensor number group are G, H, I, J, K, where G, H, I are for the first trailer and J, K are for the second trailer, it is considered that there is a connection relationship between the first trailer and the first tractor. Then, match according to the number of the target tractor and the number of the target trailer, that is, bind the two vehicles and determine that the first tractor is towing the first trailer.

[0052] Step S204 includes the following steps (Determining the number of the target trailer according to all the above-mentioned temperature and pressure sensor numbers in the second sensor number group and the number of the target tractor, includes):

[0053] Step S2041: Extract multiple second target temperature and pressure sensor number groups from all the above-mentioned temperature and pressure sensor numbers in the second sensor number group. Each second target temperature and pressure sensor number group includes at least one of the above-mentioned temperature and pressure sensor numbers in the second sensor number group. The temperature and pressure sensor numbers in the second target temperature and pressure sensor number group correspond to the number of the trailer.

[0054] Specifically, for example, if the temperature and pressure sensor numbers in the second sensor number group are G, H, I, J, K, where G, H, I are for the first trailer and J, K are for the second trailer, since the number of temperature and pressure sensor numbers of the first trailer is greater than that of the second trailer, it is considered that the target trailer is the first trailer.

[0055] Step S2042: Use the number of the trailer corresponding to the second target temperature and pressure sensor number with the largest quantity among the above-mentioned temperature and pressure sensor numbers as the number of the target trailer, so as to determine that the target trailer is connected to the target tractor.

[0056] Specifically, there is a connection relationship between the first trailer and the first tractor. Then, according to the numbers of the target tractor and the target trailer, a match is made, that is, the two vehicles are bound, and it is determined that the first tractor is towing the first trailer.

[0057] In the process of determining the number of the target trailer according to all the above temperature and pressure sensor numbers in the above temperature and pressure sensor number group of the trailer and the number of the above target tractor, the above method further includes: According to W g =(N all -N g )+ID g , the wheel position of the above trailer is determined to determine the wheel position of the above trailer corresponding to each of the above temperature and pressure sensor numbers. The wheel position of the above trailer is used to represent the position of the tire of the above trailer. W g is the wheel position of the above trailer, N all is the total number of tires, N g is the number of tires of the above trailer, and ID g is the tire number of the above trailer.

[0058] For example: The tractor has 10 wheel positions, and the trailer has 12 wheel positions. The tractor and the trailer exist as individuals. Then the wheel position numbers of the tractor should be wheel positions 1-10; the wheel position numbers of the trailer are 1-12. If the tractor and the trailer are regarded as a whole vehicle, the wheel position numbers should be 1-22. In this way, the wheel positions need to be strung together for display, so the wheel positions of the trailer should be 11-22.

[0059] Specifically, since a tractor has 10 tires and a trailer has 12 tires, the wheel positions of the tractor are the wheel positions among the total tires (i.e., 22 tires). After obtaining each wheel position, it is convenient to present the states of the temperature and pressure sensors of each tire on the display screen later, which is convenient for subsequent monitoring of the states of the tires of the tractor and the trailer.

[0060] In an embodiment of the present application, the above method further includes: receiving the temperature and pressure sensor number group sent by the target receiver every predetermined time. The above predetermined time is greater than or equal to 1 minute and less than or equal to 60 minutes. That is, the predetermined time is within 1 hour, which is convenient for subsequent re-binding. For example, if the first tractor is bound to the second trailer later, then the previous binding between the first tractor and the first trailer will be unbound at the same time.

[0061] Through the above embodiments, by collecting the numbers of multiple voltage stabilizing sensors and based on all the numbers of voltage stabilizing sensors, the automatic binding and unbinding of the tractor and the trailer are realized, so as to better realize the automated management of the commercial vehicle fleet, improve the driving safety of commercial vehicles, ensure the accurate management and monitoring of trailer data in commercial vehicles, reduce the workload and error rate of manual operations, and thus solve the problem of low matching efficiency between the tractor and the trailer in the existing automatic trailer swapping technology.

[0062] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the implementation process of the matching method for the tractor and the trailer of the present application will be described in detail below in conjunction with specific embodiments.

[0063] This embodiment relates to a specific matching method for a tractor and a trailer, including the following steps:

[0064] Step S1: The receiver randomly grabs a certain number of temperature and pressure sensor IDs and transmits them to the display. The display will record and detect the number of times each temperature and pressure sensor ID appears. When the number of times each temperature and pressure sensor ID appears is greater than 5 times, the temperature and pressure sensor ID is determined to be valid. At this time, the display only obtains the valid and disordered temperature and pressure sensor IDs, and the display cannot yet determine the wheel position of each temperature and pressure sensor. Wait for the background system to calculate and process the wheel position allocation of the temperature and pressure sensor IDs on the tractor Q and the trailer, and then send it to the display for the display of the wheel position and the temperature and pressure sensor.

[0065] Step S2: The processing platform receives all the temperature and pressure sensor IDs on the display ID, the tractor Q, the trailer A, and the trailer B. Find the corresponding tractor Q according to the ID of the display, and then find the tire numbers and all the corresponding temperature and pressure sensor IDs stored in the tractor Q, as well as the wheel position of the tire on the tractor Q; through the exclusion method from all the temperature and pressure sensor IDs, exclude the temperature and pressure sensor IDs of the tractor Q from all the temperature and pressure sensor IDs, and then find the temperature and pressure sensor IDs of the trailer A or the trailer B from the remaining temperature and pressure sensor IDs.

[0066] Step S3: Among the remaining temperature and pressure sensor IDs, match them with the temperature and pressure sensor IDs on the trailer A and the trailer B respectively, and calculate the share of the number of temperature and pressure sensor IDs in the trailer A and the trailer B in the remaining temperature and pressure sensor IDs. The trailer with the larger share of the number of temperature and pressure sensor IDs is considered to be the trailer bound to the tractor Q.

[0067] Step S4: According to the wheel position layout of the tractor Q and the trailer (A or B), calculate the total number of tires of the whole vehicle and the total number of tires of the tractor, and find the wheel positions of the tires on the trailer (A or B); in this way, the total number of tires of the whole vehicle sent to the display can be calculated.

[0068] Regardless of how the trailers are swapped, the tractor can automatically replace the trailers accurately according to the actual situation of the vehicle, ensuring real-time monitoring of the vehicle's running status.

[0069] 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 the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than here.

[0070] The embodiment of the present application also provides a processing platform. It should be noted that the processing platform of the embodiment of the present application can be used to execute the matching method for the tractor and the trailer provided by the embodiment of the present application. The processing platform is used to implement the above-mentioned embodiment and the preferred implementation manner, and those that have been described will not be repeated.
