Description

Technical Field

[0001] The present invention relates to the field of vehicle communication technology, and in particular to a TBOX network testing method, device and computer-readable storage medium. Background Art

[0002] T-BOX (Telematics Box, remote communication terminal) is an important component of the vehicle intelligent network system. T-BOX mainly interacts with the controller area network (CAN) bus, vehicle computer, and telematics service provider (TSP) to realize the key functions of vehicle intelligent network.

[0003] In order to meet the requirements of advanced assisted driving and other functions, more and more electronic components are needed to participate in information interaction. The on-board Ethernet connection method is flexible and compact, which can greatly reduce the weight of the vehicle wiring harness. Through high bandwidth, it can achieve fast program refresh, audio, video and other streaming media high-speed transmission.

[0004] At present, the Ethernet of the T-BOX terminal provides Ethernet routing for key automotive domain controllers (Domain Control Unit, DCU), such as smart cockpits and autonomous driving, so the hardware reliability of its Ethernet path is particularly important. In the DV (Design Verification) test of automotive parts, tests such as electrical load, electromagnetic compatibility, high temperature, low temperature, humidity, drop, vibration, impact, salt spray, etc. are carried out to ensure hardware reliability. This requires checking whether the Ethernet path of the T-BOX terminal is normal after each test item.

[0005] Traditional Ethernet is generally connected using RJ45 connectors, but in-vehicle Ethernet does not specify a specific connector, so the types of Ethernet connectors on T-BOX terminals vary. More importantly, in-vehicle Ethernet T1 only has two wires, while traditional Ethernet has eight wires, so conventional T-BOX terminal Ethernet channel testing often requires an additional Ethernet converter to achieve the conversion and interconnection between T1 and RJ45. It is necessary to first convert from the T1 port of the T-BOX terminal to a dedicated Ethernet converter, and then convert from the converter to a common RJ45 port and connect to the test computer. For example, if the T-BOX terminal has one Ethernet channel, an Ethernet converter is required, and if the T-BOX terminal has 6 Ethernet channels, six Ethernet converters are required. In addition, each Ethernet channel needs to be configured as a master and slave, which brings great inconvenience to the test, and also increases additional costs and is inefficient. Summary of the invention

[0006] In order to overcome the deficiencies in the prior art, the present invention aims to provide a TBOX network testing method, device and computer-readable storage medium to solve the problems of cumbersome steps, high cost and low efficiency in the current TBOX network testing.

DETAILED DESCRIPTION

[0019] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0020] In the subsequent description, the suffixes such as "module", "component" or "unit" used to represent elements are only used to facilitate the description of the present invention, and have no specific meanings. Therefore, "module", "component" or "unit" can be used in a mixed manner.

[0021] Figure 1 This embodiment proposes a TBOX network testing method, which is applied to a tool end, one end of which is connected to a test end via a data cable, and the other end of which is connected to a tested end via an Ethernet cable. The method comprises: S1. Obtain a first network address of the tested terminal, and determine the address segment to which the first network address belongs; S2, allocating a second network address of the tool end and a third network address of the test end in the address segment, wherein the first network address, the second network address and the third network address are different; S3. Setting the tool end and the tested end to slave configuration and master configuration respectively, so that the diagnostic signal of the test end reaches the tested end via the tool end.

[0022] In this embodiment, please refer to Figure 5The working principle diagram of the TBOX network testing method of the present invention is shown. First, a T-BOX terminal is taken as a tool terminal, and the tool terminal is the same terminal as the "tested T-BOX terminal", that is, this T-BOX terminal is called a "tool T-BOX terminal". Considering that the two terminals are exactly the same, their Ethernet interfaces are also exactly the same, so the two T-BOX terminals can be directly connected by an Ethernet cable; then, taking a single Ethernet as an example, when doing a path test, first configure the "tool T-BOX terminal" as a slave configuration (Slave), and then set the "tested T-BOX terminal" as the master configuration (Master); finally, set the IP addresses of the test PC, the "tool T-BOX terminal" and the "tested T-BOX terminal" in the same address segment, for example, the target IP address of the "tested T-BOX terminal" is set to 192.168.1.1, the IP address of the "tool T-BOX terminal" is set to 192.168.1.2, and the IP address of the test PC is set to 192.168.1.8. At this time, when the test PC is connected to the "tool T-BOX terminal" via a USB cable, and then pings the IP address 192.168.1.1 of the "tested T-BOX terminal", it can be pinged through.

[0023] It can be seen that in this embodiment, the above-mentioned "tool T-BOX terminal" plays the role of a tool and a routing conversion, thereby conveniently realizing the mutual ping-through from the test PC (192.168.1.8) to the device under test (192.168.1.1), and realizing the continuity test of the Ethernet path of the device under test.

[0024] Similarly, in this embodiment, the method for implementing multiple Ethernets can also adopt operations similar to the above scheme. For example, if the device under test has four Ethernets, four IP addresses are configured on the tool terminal and the device under test respectively, so that each Ethernet can be pinged separately on the test PC; further, in this embodiment, a batch test script is edited on the test PC to ping four Ethernets at the same time, which will greatly improve the test efficiency without adding extra costs.

[0025] The beneficial effect of this embodiment is that by obtaining the first network address of the tested end and determining the address segment to which the first network address belongs; allocating the second network address of the tool end and the third network address of the test end in the address segment, wherein the first network address, the second network address and the third network address are different; setting the tool end and the tested end as slave configuration and master configuration respectively, so that the diagnostic signal of the test end reaches the tested end via the tool end. An efficient and convenient TBOX network test solution is realized, which simplifies the implementation steps of TBOX network test, saves the software, hardware and time costs of the test process, and improves production efficiency.

[0026] Figure 2 This is a second flow chart of the TBOX network testing method of the present invention. Based on the above embodiment, obtaining the first network address of the tested terminal further includes: S11, obtaining the number of Ethernet networks of the tested end; S12. Determine a plurality of the first network addresses corresponding to the number.

[0027] In this embodiment, when the number of Ethernet networks of the tested end is greater than one, multiple first network addresses of the tested end are determined accordingly; further, the multiple first network addresses are written to the test end, and the test end records the multiple first network addresses of the same TBOX under test and associates them with the model information of the TBOX, thereby facilitating batch execution of test tasks for multiple groups of TBOX under test at the test end.

[0028] Furthermore, in this embodiment, determining the address segment to which the first network address belongs further includes: respectively setting an address segment corresponding to each of the first network addresses, wherein the multiple address segments obtained by setting are different from each other.

[0029] In this embodiment, when a tested TBOX has multiple different first network addresses, address segments corresponding to each of the first network addresses are set at the test end, wherein the multiple address segments obtained by setting are different from each other. At the same time, the set multiple address segments are associated with the model information of the tested TBOX and recorded.

[0030] Furthermore, in this embodiment, determining the address segment to which the first network address belongs further includes: performing statistics on the address segment corresponding to each of the first network addresses to determine multiple first network addresses belonging to the same address segment.

[0031] In this embodiment, when a tested TBOX has multiple different first network addresses and at least two addresses belong to the same address segment, all the first network addresses are divided to determine multiple first network addresses belonging to the same address segment; or, two addresses belonging to the same address segment are re-divided into two different address segments to avoid mutual influence during the testing of the corresponding two paths.

[0032] Furthermore, in this embodiment, allocating the second network address of the tool end and the third network address of the test end in the address segment further includes: setting the second network address and the third network address in multiple address segments respectively, wherein the first network address, the second network address and the third network address in each address segment are different.

[0033] In this embodiment, the first network address, the second network address and the third network address are grouped, and the three addresses in each group are different from each other and belong to the same address segment.

[0034] Furthermore, in this embodiment, allocating the second network address of the tool end and the third network address of the test end in the address segment further includes: for multiple first network addresses belonging to the same address segment, correspondingly setting different second network addresses and third network addresses in the same address segment.

[0035] In this embodiment, at the test end, a one-to-one correspondence is established between the first network address, the second network address and the third network address, so that even in the above situation, each path of the tested end can be tested individually.

[0036] Figure 3 This is the third flow chart of the TBOX network testing method of the present invention. Based on the above embodiment, the tool end and the tested end are respectively set to slave configuration and master configuration, further comprising: S31, detecting whether the number of Ethernets is greater than a preset value; S32. If the number of the Ethernets is greater than the preset value, a batch test script is created, and test paths corresponding to the number of entries are created in the batch test script, wherein each test path includes a diagnostic signal transmission path corresponding to the first network address, the second network address and the third network address.

[0037] In this embodiment, for example, if the number of networks at the tested end is three, three manual testing operations are still used. If the number of networks at the tested end is more than three, a batch test script is created through the test end, and test paths corresponding to the number of entries are created in the batch test script, wherein each test path includes a diagnostic signal transmission path corresponding to the first network address, the second network address and the third network address.
