Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
In the prior art, when the remote diagnosis is carried out on the automobile, the situation that the network cards of different types conflict in the same network segment exists, so that the remote diagnosis cannot be normally carried out due to abnormal networking, and the stability of the remote diagnosis is reduced. In order to overcome the technical problems, the application provides a network card communication configuration method which can ensure that remote diagnosis is smoothly and normally carried out and improve the stability of the remote diagnosis.
The embodiment of the application discloses a network card communication configuration method which is applied to vehicle communication interface equipment, and is shown in fig. 1, and the method can comprise the following steps:
step S11: acquiring a first IP (Internet protocol) address corresponding to a networking network card and a second IP address corresponding to a local network card; the networking network card is a network card for connecting with the Internet, and the local network card is a network card except the networking network card.
In this embodiment, the IP address corresponding to the networking network card is first obtained as the first IP address, and the IP address corresponding to the local network card is second IP address, where the networking network card is a network card for connecting to the internet, and the local network card is a network card other than the networking network card, that is, the two types of network cards are substantially identical, and in this embodiment, the networking network card and the local network card are distinguished by functions, which may affect internet access if they are located in the same network segment. Namely a networking network card or wifi is a networking network card. The local network card may be an ethernet card for performing vehicle diagnosis communication through TCP/IP (Transmission Control Protocol/Internet Protocol ) and ethernet based on UDS (Unified Diagnostic Services, unified diagnostic service) for dopp (Diagnostic over Internet Protocol), or a USB (Universal Serial Bus, serial communication bus) virtual network card, wifi, ethernet card for J2534 (one pair of upper receiving application software, and a programming interface driven by a lower receiving host computer) communication, or may be added to a bridge, and IP is uniformly distributed to the outside of the bridge, where the local network card may be the IP of the bridge, and the added bridge or each network card may be independently distributed with IP, which is not limited herein.
In this embodiment, the obtaining the first IP address corresponding to the networking network card and the second IP address corresponding to the local network card may include: and when the vehicle communication interface equipment receives the remote diagnosis instruction, acquiring a first IP address corresponding to the networking network card and a second IP address corresponding to the local network card. When entering the vehicle remote diagnosis flow, the IP addresses corresponding to the networking network card and the local network card are obtained first.
The present embodiment may be applied to a vehicle communication interface device (VCI-vehicle communication interface) that is primarily used for communication, has a specific software interface, and is programmed to implement diagnostic services, in fact even if the computer is in communication with the vehicle. For example, the vehicle diagnostic system shown in fig. 2 is a schematic structural diagram of a vehicle diagnostic system, in which the b\c terminal connector is a vehicle communication interface device, which is connected to a router or a hotspot of a client through ethernet, wifi, and performs remote diagnosis through Internet interactive data. When DOIP remote diagnosis is carried out, the C end distributes IP to the vehicle through another network card to communicate with the vehicle. And the end B applies IP to the diagnostic instrument through another network card, and communicates with the diagnostic instrument after being distributed to the IP. When J2534 remote is carried out, the B-end connector is connected with the PC through the USB, and IP is distributed to the PC through a USB virtual network card (wifi or Ethernet) and communication is carried out.
Step S12: and judging whether the first IP address and the second IP address are in the same network segment.
In this embodiment, after the first IP address and the second IP address are obtained, whether the first IP address and the second IP address are in the same network segment is determined, that is, whether the first IP address and the second IP address are in the same network segment is determined according to the existing network segment division condition of the network segment. It can be understood that the router or the IP of the hotspot is set by the user, and the IP of the vehicle communication interface device is set by the vehicle communication interface device, so that the local network card and the networking network card are inevitably in the same network segment, thereby causing conflict, failing to normally network, and causing the situation that remote diagnosis cannot be performed.
In this embodiment, the determining whether the first IP address and the second IP address are after the same network segment may further include: if the network is not in the same network segment, the local network card and the networking network card directly communicate according to the current configuration parameters. If the first IP address and the second IP address are not in the same network segment, namely the local network card and the networking network card cannot influence each other, the two network cards can directly communicate according to the current address.
Step S13: if the network is in the same network segment, selecting a corresponding target IP address for the local network card; the target IP address and the first IP address are in different network segments.
In this embodiment, if the first IP address and the second IP address are in the same network segment, a new IP address is selected for the local network card, and the new IP address and the first IP address are in different network segments, i.e. the IP address of the local network card is modified to other network segments, so that the IP address of the networking network card and the IP address of the local network card do not collide.
In this embodiment, the selecting a corresponding target IP address for the local network card may include: determining an original network segment in which the first IP address and the second IP address are located; and randomly selecting an IP address from any network segment except the original network segment as the target IP address for the local network card. When the target IP address is selected for the local network card, one IP address is selected randomly from any network segment except the network segment where the first IP address is located, namely, the networking network card and the local network card are ensured not to be in the same network segment. In this case, only the target IP address is selected, but the address is actually put into use.
In this embodiment, the selecting a corresponding target IP address for the local network card may include: selecting a corresponding target IP address for the local network card, and sending a network detection message to all devices corresponding to a target network segment where the target IP address is located in a broadcasting mode according to an address resolution protocol; judging whether the target IP address is used or not according to the received response corresponding to the network detection message; if yes, the step of selecting the corresponding target IP address for the local network card is re-executed until the unused target IP address is selected. It can be understood that if the selected target IP address is already used, it cannot be provided to the local network card for use, if the target IP address is directly and easily conflicted, so after the target IP address is selected, it is detected first whether the IP address is occupied, if not, it can be used, if so, it needs to be selected again, and it is detected again until the target IP address which is not occupied and is different from the first IP address is selected. The detection of the target IP address may be performed by sending a network detection message, specifically, the network detection message may be sent to all devices corresponding to the target network segment where the target IP address is located by broadcasting according to an address resolution protocol (ARP, address Resolution Protocol), and if a certain IP address is occupied, a corresponding response may be fed back, so that whether the target IP address is occupied may be determined according to the received response.
Step S14: and configuring the local network card according to the target IP address so that the local network card can communicate according to the target IP address, and the networking network card can communicate according to the corresponding configuration parameters.
In this embodiment, after the target IP address is determined, the configuration for the local network card is performed based on the target IP address, and after the configuration, the local network card can communicate through the target IP address, so that the local network card and the networking network card perform remote diagnosis on the vehicle according to the configuration parameters.
In this embodiment, the configuring the local network card according to the target IP address may include: stopping the dynamic host configuration protocol service, and setting the IP address of the local network card as the target IP address by modifying a configuration file corresponding to the dynamic host configuration protocol service; restarting the dynamic host configuration protocol service. Specifically, the dynamic host configuration protocol service (DHCP, dynamic Host Configuration Protocol) is stopped, the configuration file corresponding to the dynamic host configuration protocol service is modified to set the IP address of the local network card as the target IP address, and then the dynamic host configuration protocol service is restarted, so that the address configuration is successful.
In this embodiment, after the configuring the local network card according to the target IP address, the method may further include: and reallocating the IP address for the networking network card according to the network segment where the first IP address is located, wherein the newly allocated IP address and the first IP address are in the same network segment. It can be understood that, because the networking network card and the local network card are in the same network segment when the previous network segments collide, the route is likely to go to the local network card at this time, the networking network card is unchanged at this time and may influence the internet surfing, and the gateway of the networking network card is certain to go to ensure the normal internet surfing by applying for the system reconfiguration route in the original network segment again.
In this embodiment, a specific vehicle remote diagnosis procedure is as follows:
1. entering a remote diagnosis;
2. reading the IP address of the local network card;
3. reading the IP address of the networking network card;
4. comparing whether the network is in the same network segment, if not, ending the process, and performing remote diagnosis;
5. selecting an IP address of one other network segment;
6. the local network card sends an Arp message, detects whether the IP is occupied, if so, executes the step 5, and does not occupy the step 7;
7. stopping the DHCP service and updating the configuration file of the DHCP service;
8. setting a local network card IP;
9. starting a DHCP service;
10. the networking network card reappears the IP address;
11. remote diagnosis is performed.
That is, in this embodiment, after entering the remote diagnosis, it is checked whether the IP addresses of the networking network card and the local network card are in the same network segment, if so, the IP of the local network card is modified to other network segments, and then an APR message is sent to inquire whether the IP is used, if not, the local network card is used, and the DHCP service is restarted, thereby solving the problem of IP address collision.
As can be seen from the above, in this embodiment, a first IP address corresponding to a networking network card and a second IP address corresponding to a local network card are obtained; the networking network card is a network card for connecting with the Internet, and the local network card is a network card except the networking network card; judging whether the first IP address and the second IP address are in the same network segment or not; if the network is in the same network segment, selecting a corresponding target IP address for the local network card; the target IP address and the first IP address are in different network segments; and configuring the local network card according to the target IP address so that the local network card can communicate according to the target IP address, and the networking network card can communicate according to the corresponding configuration parameters. Therefore, the problem of IP address conflict is solved, the smooth and normal remote diagnosis is ensured, and the stability of remote diagnosis is improved by checking whether the IP addresses of the networking network card and the local network card are in the same network segment and dynamically modifying the IP address of the local network card in the background through the vehicle communication interface equipment end when the networking network card and the local network card are in the same network segment.
Correspondingly, the embodiment of the application also discloses a network card communication configuration device, which is shown in fig. 3, and comprises the following steps:
