It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present invention described herein can be implemented in an order different from those illustrated or described herein.

[0029] Embodiment 1

[0030] According to an embodiment of the present invention, a method embodiment of a method for determining a data transmission network 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 an order different from that here.

[0031] Figure 1 is a flowchart of a method for determining a data transmission network according to an embodiment of the present invention, as Figure 1 shown, the method includes the following steps:

[0032] Step S102, obtaining multiple historical timestamps of the data to be transmitted under multiple transmission networks, where the historical timestamp is the timestamp of the previous frame before the data to be transmitted enters the transmission network;

[0033] As an optional embodiment, before obtaining multiple historical timestamps of the data to be transmitted under multiple networks, the method further includes: performing an operation of adding a timestamp to the header of the data to be transmitted; inputting the data to be transmitted into multiple transmission networks through a first target system, where the first target system at least includes: a vehicle-mounted system, a ground system.

[0034] In the above optional embodiments, it is specifically divided into two cases: First, when the ground system sends data, a timestamp is added to the data header (or other parts). The timestamp occupies 10 bytes of space. The timestamp is the total number of milliseconds from 00:00:00 on January 1, 1970 Greenwich Mean Time (08:00:00 on January 1, 1970 Beijing Time) to the present. It will not generate duplicates and also avoids the overflow and clearing of life signals and frame sequence numbers, providing a more convenient judgment method for the vehicle-mounted system to select and discard data.

[0035] Second, when the vehicle-mounted system sends data, a timestamp is added to the data header (or other parts). The timestamp occupies 10 bytes of space. The timestamp is the total number of milliseconds from 00:00:00 on January 1, 1970 Greenwich Mean Time (08:00:00 on January 1, 1970 Beijing Time) to the present. It will not generate duplicates and also avoids the overflow and clearing of life signals and frame sequence numbers, providing a more convenient judgment method for the ground system to select and discard data.

[0036] Optionally, embodiments of the present invention can use frame sequence numbers 0 - 65535 as the basis for data selection. Other frame sequence numbers, such as 0 - 210, 0 - 220, etc., can also achieve data selection using the same principle.

[0037] Optionally, the data selection method of the embodiments of the present invention is based on the premise that the single-packet transmission delay time difference between the 4G private network and the 5G network does not exceed 5 s, and there is no loss of 25 consecutive packets in the 4G private network and the 5G network. If this premise is changed to other parameters, the corresponding frame sequence number range of the data selection method can also achieve the same result after corresponding changes.

[0038] Step S104, determine whether multiple historical timestamps are zero and obtain multiple first determination results;

[0039] Step S106, based on the multiple first determination results, compare the timestamps of multiple transmission networks to obtain a comparison result, where the timestamp includes a historical timestamp and / or a current timestamp, and the current timestamp is the timestamp of the current frame when the data to be transmitted is input to the transmission network.

[0040] As an alternative embodiment, based on multiple first judgment results, the timestamps of multiple transmission networks are compared to obtain a comparison result, including: when the first judgment result is that the historical timestamp is zero, obtaining the current timestamp in the transmission network, comparing the current timestamps of any two different transmission networks among the multiple transmission networks to obtain a comparison result; when the first judgment result is that the historical timestamp is not zero, obtaining the current timestamp in the transmission network, comparing the current timestamp of the same transmission network with the historical timestamp to obtain a first comparison result, processing the current timestamp based on the first comparison result, and comparing the current timestamps of any two different transmission networks among the multiple transmission networks based on the processing result to obtain a comparison result.

[0041] In the above alternative embodiment, after the vehicle-mounted system is powered on, the storage space representing the reception timestamp of the previous frame of data is default set to zero. After the vehicle-mounted system receives the data frames of two ground systems, the timestamps of the two data frames are respectively extracted. If the reception timestamp of the previous frame of data is 0 at this time, it means that this data frame is the first frame of data received by this channel. The timestamps of the two data frames are respectively compared, and the data frame with the larger timestamp is taken as the real data frame for reception and processing, and the data frame with the smaller timestamp is discarded.

[0042] Similarly, after the ground system is powered on, the storage space representing the reception timestamp of the previous frame of data is default set to zero. After the ground system receives the data frames of two vehicle-mounted systems, the timestamps of the two data frames are respectively extracted. If the reception timestamp of the previous frame of data is 0 at this time, it means that this data frame is the first frame of data received by this channel. The timestamps of the two data frames are respectively compared, and the data frame with the larger timestamp is taken as the real data frame for reception and processing, and the data frame with the smaller timestamp is discarded.

[0043] As an alternative embodiment, processing the current timestamp based on the first comparison result includes: when the first comparison result is that the current timestamp is less than the historical timestamp, destroying the data to be transmitted.

[0044] In the above alternative embodiment, after the vehicle-mounted system receives the subsequent data frames of two ground systems, the timestamps of the two data frames are respectively extracted and compared with the timestamps of the previous frames of the two data frames. If the timestamp of this frame is larger than the timestamp of the previous frame, then this frame is the latest data frame of this channel. After the latest data frames of the 4G and 5G channels are determined, the timestamps of the two channels are compared, and the data frame with the larger timestamp is taken as the real data frame for reception and processing.

[0045] After receiving the subsequent data frames of the two vehicle-mounted systems, the same ground system extracts the timestamps of the two data frames respectively, and compares them with the timestamps of the previous frames of the two data frames. If the timestamp of this frame is larger than the timestamp of the previous frame, then this frame is the latest data frame of this channel. After the latest data frames of the 4G and 5G channels are determined, compare the timestamps of the two channels, and take the data frame with the larger timestamp as the real data frame for reception and processing.

[0046] Step S108, based on the comparison result, determine the target network, where the target network is one of multiple transmission networks.

[0047] As an optional embodiment, after determining the target network, the method further includes: using the target network to transmit the data to be transmitted to the second target system, where the second target system at least includes: a vehicle-mounted system, a ground system.

[0048] As an optional embodiment, based on the comparison result, determining the target network includes: when the current timestamp of the transmission network is greater than the current timestamps of other transmission networks, determining the transmission network as the target network.

[0049] As an optional embodiment, the transmission network at least includes: a 4G transmission network and a 5G transmission network at the same time.

[0050] As can be seen from the above, in the embodiment of the present invention, first, multiple historical timestamps of the data to be transmitted under multiple transmission networks can be obtained, where the historical timestamp is the timestamp of the previous frame before the data to be transmitted enters the transmission network; then it can be judged whether the multiple historical timestamps are zero and multiple first judgment results are obtained; then based on the multiple first judgment results, the timestamps of the multiple transmission networks can be compared to obtain a comparison result, where the timestamp includes a historical timestamp and / or a current timestamp, and the current timestamp is the timestamp of the current frame when the data to be transmitted enters the transmission network; finally, based on the comparison result, the target network can be determined, where the target network is one of multiple transmission networks. Through the method for determining a data transmission network provided by the embodiment of the present invention, the purpose of determining which communication network to use for data transmission by inputting the transmission data into multiple different communication networks and then comparing the timestamps corresponding to the multiple different communication networks is achieved, thereby realizing the technical effect of improving the stability of network data transmission, and further solving the technical problem of poor transmission stability of using a single-point network during open-pit production in related technologies.

[0051] Therefore, the embodiments of the present invention mainly have the following improvements and innovations:

[0052] 1. The 4G private network and 5G network are used simultaneously for vehicle-ground data transmission, reducing the blind area of the open-pit mine network coverage, reducing the impact of network single-point failures on the unmanned truck system, and greatly increasing the stability of vehicle-ground data transmission.

[0053] 2. The timestamp mechanism is used to select the 4G private network data, 5G network data, and dual-channel data, ensuring that the data received by the ground system and the vehicle-mounted system is the latest data and ensuring the control accuracy of the mining trucks.
