Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the 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 detecting the product terminal, the detection equipment is often far away from the product terminal, so that physical connection between the detection equipment and the first data transmission end and between the product terminal and the second data transmission end is not necessarily established at the same time, and further detection failure is caused.
Therefore, the embodiment of the application provides a communication connection establishment method scheme, which can greatly reduce detection failure caused by that the detection equipment does not receive a message.
The embodiment of the application discloses a 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 connected with a product terminal physically. Referring to fig. 1, the method includes:
step S11: and when the first data transmission end and the detection equipment are detected to establish physical connection, starting timing operation.
It should be noted that the present embodiment may start the timing operation in various manners, for example, by setting a timer, and is not particularly limited herein.
Step S12: and if the target message is not received within the time specified by the timing operation, notifying the product terminal to broadcast the target message through the second data transmission terminal.
In this embodiment, if the target message is not received within the time specified by the timing operation, the first data transmission end actively sends an instruction to the second data transmission end, so as to notify the product terminal to broadcast the target message 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 report specifically includes: notifying a target gateway in the product terminal to broadcast the target message through the second data transmission end; wherein each of the product terminals includes one or more of the target gateways.
Step S13: and acquiring the target message broadcasted by the product terminal and sent by the second data transmission end, and sending the target message to the detection equipment.
In this embodiment, after receiving the notification of the second data transmission end, the product terminal broadcasts the target message, and the first data transmission end obtains the target message broadcasted by the product terminal and sent by the second data transmission end, and sends the target message to the detection device.
Step S14: and establishing target communication connection with the detection equipment.
In this embodiment, after the target message 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 realizes remote detection of the product terminal by establishing the target communication connection.
Therefore, in the specified time, if the first data transmission end does not receive the target message broadcast by the product terminal, the first data transmission end actively informs the product terminal of broadcasting the target message through the second data transmission end, so that the problem of detection failure caused by that the detection equipment does not receive the target message can be greatly reduced.
In a specific embodiment, establishing the 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 of starting the timing operation until the first data transmission end establishes target communication connection with the detection equipment. Therefore, the method and the device can re-execute the step of starting the timing operation under the condition that the detection equipment does not receive the target message, so as to judge whether the target message is received or not, until the first data transmission end and the detection equipment establish target communication connection, and therefore the method and the device can avoid the problem of detection failure caused by the fact that the detection equipment does not receive the target message.
In another specific embodiment, establishing the target communication connection with the detection device may specifically include: and if the target message is received within the time specified by the timing operation, broadcasting the target message to the detection equipment, and re-executing the step S11, the step S12 and the step S13 of starting the timing operation until the first data transmission end and the detection equipment establish target communication connection. 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 is not established between the first data transmission end and the detection equipment until the first data transmission end and the detection equipment establish the target communication connection, so that the method and the device can ensure that the first data transmission end and the detection equipment establish the target communication connection.
In this embodiment, since each target gateway in the product terminal broadcasts the target message, when the target messages broadcast by all the target gateways in the product terminal are received, it is determined that the first data transmission end and the detection device establish the target communication connection, and the step of executing the start 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, the second data transmission end is connected with a product terminal in a physical mode, and compared with the previous embodiment, the technical scheme is further described and optimized. Referring to fig. 2, the method specifically includes:
step S21: and when the first data transmission end and the detection equipment are detected to establish physical connection, starting timing operation.
In comparison with the above embodiment, the detecting device in this embodiment may be a diagnostic apparatus, that is, when it is detected that the first data transmission end and the diagnostic apparatus are physically connected, 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 terminal to broadcast the request message so that the product terminal broadcasts the target message after receiving the request message.
In comparison with the above embodiment, the product terminal in this embodiment may be a vehicle, and the target message may be a vehicle notification message. In this way, in this embodiment, if the vehicle notification message is not received within the time specified by the timing operation, the request message is broadcast through the second data transmission end, the vehicle broadcasts the vehicle notification message after receiving the request message broadcast by the second data transmission end, and further, the second data transmission end sends the vehicle notification message to the first data transmission end after receiving the vehicle notification message.
Step S23: and acquiring the target message broadcasted by the product terminal and sent by the second data transmission end, and sending the target message to the detection equipment.
Based on the descriptions of the step S21 and the step S22, the step of obtaining the target message broadcasted by the product terminal and sent by the second data transmission end, and sending the target message to the detection device may specifically include: and acquiring the vehicle statement message which is sent by the second data transmission end and broadcast by the vehicle, 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 description of step S21, step S22 and step S23, the present embodiment can establish a target communication connection with the diagnostic apparatus, and thus, the present embodiment can implement remote diagnosis of the vehicle based on the target communication connection.
As can be seen, the present application proposes a communication connection establishment method applied to a first data transmission end, including: when the first data transmission end and the detection equipment are detected to establish physical connection, starting timing operation; if the target message is not received within the time specified by the timing operation, notifying the second data transmission terminal to broadcast a request message so that the product terminal broadcasts the target message after receiving the request message; acquiring the target message broadcasted by the product terminal and sent by the second data transmission end, and sending the target message to the detection equipment; the first data transmission end can actively inform the product terminal of broadcasting the target message through the second data transmission end if the first data transmission end does not receive the target message sent by the product terminal in a specified time, 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 remote diagnosis of a vehicle, under normal conditions, the server side first establishes physical connection with the target vehicle, then the target vehicle broadcasts a vehicle statement message (usually broadcast three times), the maintenance side forwards the received message to the server side, after the received message is received by the server side, the vehicle statement message is broadcast to a preset diagnostic apparatus through the physical connection of the DOIP, after the received message is received by the diagnostic apparatus, a TCP connection is established with the server side, and interaction of the diagnostic message is started.
However, in the actual use process, the service end and the maintenance end are far apart, so that the time for establishing the DOIP physical connection between the service end and the maintenance end is not necessarily the same. For example, if the maintenance end has 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 established a DOIP physical connection at this time, the diagnostic apparatus cannot receive the broadcast, and cannot establish a TCP connection later. For another example, in the diagnosis process, the physical connection between the server and the diagnostic apparatus is disconnected for some reasons, and after reconnection, the target vehicle does not know that the server and the diagnostic apparatus have been reconnected, so that the target vehicle cannot broadcast, and therefore the diagnostic apparatus cannot receive the vehicle broadcast, and the remote diagnosis fails.
For the above case, referring to fig. 3, the present application applies the communication connection establishment method to a TCP connection establishment process for vehicle remote diagnosis. Specifically, the first data transmission end is a service end in a preset diagnostic box, namely a B-end connector in fig. 3, the second data transmission end is a maintenance end in the preset diagnostic box, namely 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 connected with a target vehicle in a DOIP physical manner.
In the TCP connection establishment process of vehicle remote diagnosis, when the fact that DOIP physical connection is established between the server side and a preset diagnostic instrument is detected, a timer is started to perform timing operation, if a vehicle statement message with Data Type of 0004 is not received within the time specified by the timer, the maintenance side is informed to broadcast a vehicle identification request message with Data Type of 0001 to the target vehicle, and therefore the target vehicle broadcasts the vehicle statement message after receiving the vehicle identification request message. After receiving the vehicle statement message broadcast by the target vehicle, the maintenance end sends the vehicle statement message to a service end through a cloud platform, and when the service end receives the vehicle statement message, the vehicle statement message is broadcast to the preset diagnostic instrument, and the step of starting the timer to perform timing operation is re-executed until the service end establishes TCP connection with the preset diagnostic instrument. And if the vehicle statement message is received within the time specified by the timer, broadcasting the vehicle statement message to the preset diagnostic instrument, and re-executing the step of starting the timer to perform timing operation until the server establishes TCP connection with the preset diagnostic instrument.
It should be noted that the specific process of judging whether the server side and the preset diagnostic apparatus establish a TCP connection is: since there may be one or more gateways in the target vehicle, and each gateway may broadcast a vehicle statement message, when receiving the vehicle statement messages broadcast by all the gateways in the target vehicle, it is determined that the server 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 statement 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 a maintenance terminal.
After the server side and the preset diagnostic instrument are connected through TCP, maintenance data of the target vehicle are obtained through the TCP connection, the preset diagnostic instrument is utilized, the maintenance data are diagnosed through the preset diagnostic instrument, corresponding diagnostic data are formed, and the diagnostic data are sent to the target vehicle through the TCP connection, so that remote diagnosis of the target vehicle is completed. In this way, if the service end and the diagnostic apparatus are not connected by TCP, or the diagnostic apparatus has not received the vehicle statement message, the service end actively notifies the target vehicle to broadcast the vehicle statement message through the maintenance end.
Correspondingly, the embodiment of the application also discloses a communication connection establishment device, as shown in fig. 4, which comprises:
a timing module 11, configured to start a timing operation when it is detected that the first data transmission end and the detection device establish a physical connection;
a target message obtaining module 12, configured to notify, if the target message is not received within a time specified by the timing operation, the product terminal to broadcast the target message through the second data transmission end;
a target message sending module 13, configured to obtain the target message broadcasted by the product terminal and sent by the second data transmission end, and send the target message to the detection device;
a communication connection establishment module 14 for establishing a target communication connection with the detection device.
