Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The system architecture related to the embodiment of the application comprises: the system comprises a cloud platform, a first data transmission end and a second data transmission end, wherein the first data transmission end and the second data transmission end are connected with the cloud platform; the first data transmission end is connected with the detection equipment, and the second data transmission end is connected with the product terminal.
When the product terminal is detected, the detection device is far away from the product terminal, so that physical connections are not necessarily established between the detection device and the first data transmission terminal and between the product terminal and the second data transmission terminal at the same time, and detection failure is caused.
Therefore, the embodiment of the present application provides a communication connection establishment method, which can greatly reduce detection failures caused by that the detection device does not receive a message.
The embodiment of the application discloses a communication connection establishing method, which is applied to a first data transmission end, wherein the first data transmission end is connected with a second data transmission end through a cloud platform, and the second data transmission end is physically connected with a product terminal. Referring to fig. 1, the method includes:
step S11: and starting timing operation when the first data transmission terminal is detected to be in physical connection with the detection equipment.
It should be noted that the present embodiment may start the timing operation in various ways, for example, by setting a timer to start the timing operation, which is not limited herein.
Step S12: and if the target message is not received within the time specified by the timing operation, informing the product terminal to broadcast the target message through the second data transmission terminal.
In this embodiment, if the target packet is not received within the time specified by the timing operation, the first data transmission end may actively send an instruction to the second data transmission end, so as to notify the product terminal to broadcast the target packet through the second data transmission end.
It should be noted that notifying, by the second data transmission end, the product terminal to broadcast the target packet specifically includes: informing a target gateway in the product terminal to broadcast the target message through the second data transmission terminal; wherein each of the product terminals includes one or more of the target gateways.
Step S13: and acquiring the target message broadcast by the product terminal and sent by the second data transmission terminal, and sending the target message to the detection equipment.
In this embodiment, the product terminal broadcasts the target packet after receiving the notification from the second data transmission terminal, and the first data transmission terminal obtains the target packet broadcasted by the product terminal and sent by the second data transmission terminal, and sends the target packet to the detection device.
Step S14: and establishing target communication connection with the detection equipment.
In this embodiment, after the target packet is sent to the detection device, a target communication connection is established with the detection device, so that the detection device can detect the product terminal based on the target communication connection, that is, the embodiment implements remote detection of the product terminal by establishing the target communication connection.
Therefore, within a specified time, if the first data transmission terminal does not receive the target message broadcasted by the product terminal, the first data transmission terminal can actively inform the product terminal to broadcast the target message through the second data transmission terminal, and therefore the problem of detection failure caused by the fact that the detection equipment does not receive the target message can be greatly reduced.
In a specific embodiment, the establishing a target communication connection with the detection device may specifically include: and if the target message is not received within the time specified by the timing operation, re-executing the step S11, the step S12 and the step S13 for starting the timing operation until the first data transmission end establishes the target communication connection with the detection device. Therefore, the method and the device can re-execute the step of starting the timing operation to judge whether the target message is received or not under the condition that the detection device does not receive the target message until the first data transmission terminal establishes the target communication connection with the detection device, and therefore the method and the device can avoid the problem of detection failure caused by the fact that the detection device does not receive the target message.
In another specific embodiment, the establishing a target communication connection with the detection device may specifically include: if the target message is received within the time specified by the timing operation, the target message is broadcasted to the detection device, and the step S11, the step S12 and the step S13 of starting the timing operation are executed again until the first data transmission terminal establishes target communication connection with the detection device. Therefore, the method and the device can re-execute the step of starting the timing operation under the condition that the target message is received but the target communication connection between the first data transmission terminal and the detection equipment is not established yet until the target communication connection between the first data transmission terminal and the detection equipment is established, and thus the method and the device can ensure that the target communication connection between the first data transmission terminal and the detection equipment is established.
In this embodiment, since each target gateway in the product terminal broadcasts the target packet, when the target packets broadcast by all the target gateways in the product terminal are received, it is determined that the first data transmission terminal establishes the target communication connection with the detection device, and the step of starting the timing operation is stopped.
The embodiment of the application discloses a specific communication connection establishment method, which is applied to a first data transmission end, wherein the first data transmission end is connected with a second data transmission end through a cloud platform, and the second data transmission end is physically connected with a product terminal. Referring to fig. 2, the method specifically includes:
step S21: and when the first data transmission terminal is detected to be in physical connection with the detection equipment, starting timing operation.
Compared with the previous embodiment, the detection device in this embodiment may be a diagnostic apparatus, that is, when it is detected that the first data transmission terminal is physically connected to the diagnostic apparatus, a timing operation is started.
Step S22: and if the target message is not received within the time specified by the timing operation, notifying the second data transmission end to broadcast the request message so that the product terminal broadcasts the target message after receiving the request message.
Compared with the previous embodiment, the product terminal in this embodiment may be a vehicle, and the target message may be a vehicle declaration message. In this way, in this embodiment, if a vehicle declaration message is not received within the time specified by the timing operation, the second data transmission terminal broadcasts the request message, the vehicle broadcasts the vehicle declaration message after receiving the request message broadcast by the second data transmission terminal, and further, the second data transmission terminal sends the vehicle declaration message to the first data transmission terminal after receiving the vehicle declaration message.
Step S23: and acquiring the target message broadcast by the product terminal and sent by the second data transmission terminal, and sending the target message to the detection equipment.
Based on the description of step S21 and step S22, the obtaining the target packet broadcasted by the product terminal and sent by the second data transmission end, and sending the target packet to the detection device may specifically include: and acquiring the vehicle statement message broadcasted by the vehicle and sent by the second data transmission terminal, and sending the vehicle statement message to the diagnostic instrument.
Step S24: and establishing target communication connection with the detection equipment.
As can be seen from the descriptions of step S21, step S22, and step S23, the present embodiment can establish the target communication connection with the diagnostic apparatus, and thus, the present embodiment can implement the remote diagnosis of the vehicle based on the target communication connection.
It can be seen that the present application provides a communication connection establishing method, applied to a first data transmission end, including: when detecting that the first data transmission terminal establishes physical connection with the detection equipment, starting timing operation; if the target message is not received within the time specified by the timing operation, notifying the second data transmission terminal of broadcasting the request message so that the product terminal broadcasts the target message after receiving the request message; acquiring the target message broadcast by the product terminal and sent by the second data transmission terminal, and sending the target message to the detection equipment; and establishing target communication connection with the detection equipment, and thus, if the first data transmission end does not receive a target message sent by the product terminal within a specified time, the first data transmission end can actively inform the product terminal to broadcast the target message through the second data transmission end, so that the problem of detection failure caused by the fact that the detection equipment does not receive the target message can be greatly reduced.
It should be noted that, in the process of vehicle remote diagnosis, under normal conditions, the service end first establishes a physical connection of the DOIP with the target vehicle, then the target vehicle broadcasts a vehicle declaration message (usually broadcast three times), the maintenance end forwards the received message to the service end, after the service end receives the message, the service end broadcasts the vehicle declaration message to a preset diagnosis instrument through the physical connection of the DOIP, after the diagnosis instrument receives the message, the service end establishes a TCP connection with the service end, and starts to perform interaction of the diagnosis message.
However, in the actual use process, since the service end and the maintenance end are far apart, the time for establishing the DOIP physical connection between the two ends is not necessarily the same. For example, if the service end has already established a DOIP physical connection with the target vehicle, the target vehicle will broadcast, but if the diagnostic apparatus and the service end have not yet established a DOIP physical connection at this time, the diagnostic apparatus will not receive the broadcast, and thus cannot establish a TCP connection later. For another example, in the process of diagnosis, physical connection between the service end and the diagnostic apparatus is disconnected due to some reasons, and after reconnection is performed, the target vehicle does not broadcast because the target vehicle does not know that the service end and the diagnostic apparatus are reconnected, so that the diagnostic apparatus cannot receive vehicle broadcasts, and remote diagnosis fails.
For the above situation, referring to fig. 3, the present application applies the communication connection establishment method to the TCP connection establishment process of vehicle remote diagnosis. Specifically, the first data transmission end is a service end in a preset diagnosis box, that is, a B-end connector in fig. 3, the second data transmission end is a maintenance end in the preset diagnosis box, that is, a C-end connector in fig. 3, the service end is connected with the maintenance end through a cloud platform, and the maintenance end is physically connected with a target vehicle by a DOIP.
In the TCP connection establishment process of vehicle remote diagnosis, when the fact that the service end establishes DOIP physical connection with a preset diagnostic instrument is detected, a timer is started to conduct timing operation, if a vehicle statement message with Data Type 0004 is not received within the time specified by the timer, the maintenance end is informed of broadcasting a vehicle identification request message with Data Type 0001 to the target vehicle, and therefore the target vehicle broadcasts the vehicle statement message after receiving the vehicle identification request message. And after receiving the vehicle statement message broadcasted by the target vehicle, the maintenance end sends the vehicle statement message to a service end through a cloud platform, and when receiving the vehicle statement message, the service end broadcasts the vehicle statement message to the preset diagnostic instrument and re-executes the step of starting the timer to perform timing operation until the service end establishes TCP connection with the preset diagnostic instrument. If the vehicle statement message is received within the time specified by the timer, the vehicle statement message is broadcasted to the preset diagnostic instrument, and the step of starting the timer for timing operation is executed again until the service end establishes TCP connection with the preset diagnostic instrument.
It should be noted that the specific process of determining whether the server establishes the TCP connection with the preset diagnostic apparatus is as follows: since there may be one or more gateways in the target vehicle, and each gateway may broadcast a vehicle declaration message, when vehicle declaration messages broadcast by all gateways in the target vehicle are received, it is determined that the service end has established a TCP connection with the preset diagnostic apparatus, and further, remote diagnosis can be performed through the TCP connection. And if the vehicle declaration message is not received or the TCP connection is not established within the time specified by the timer, broadcasting a vehicle identification request message through the maintenance terminal.
After the server side establishes TCP connection with the preset diagnostic instrument, the service data of the target vehicle are obtained through the TCP connection, the preset diagnostic instrument is used for diagnosing the service data to form corresponding diagnostic data, and the diagnostic data are sent to the target vehicle through the TCP connection to finish remote diagnosis of the target vehicle. Therefore, if the service end and the diagnostic instrument do not establish TCP connection or the diagnostic instrument does not receive the vehicle statement message, the service end can actively inform a target vehicle to broadcast the vehicle statement message through the maintenance end, and therefore the problem of diagnosis failure caused by the fact that the diagnostic instrument does not receive the vehicle statement message can be greatly reduced.
Correspondingly, an embodiment of the present application further discloses a communication connection establishing apparatus, and as shown in fig. 4, the apparatus includes:
a timing module 11, configured to start a timing operation when detecting that the first data transmission end establishes a physical connection with the detection device;
a target message obtaining module 12, configured to notify the product terminal to broadcast the target message through the second data transmission terminal if the target message is not received within the time specified by the timing operation;
a target message sending module 13, configured to obtain the target message broadcast by the product terminal and sent by the second data transmission end, and send the target message to the detection device;
and a communication connection establishing module 14, configured to establish a target communication connection with the detection device.
