The vehicle-mounted communication terminal 121 forwards the vehicle data to the collector 112 every time it receives the vehicle data sent by the electronic control unit. As shown in fig. 4, after receiving first vehicle data of the electronic control unit at time T1, the vehicle-mounted communication terminal 121 immediately forwards the first vehicle data to the collector 112, and after receiving second vehicle data of the electronic control unit at time T2, immediately forwards the second vehicle data to the collector 112. Wherein T2= T1+ T, tn = T1+ (n-1) × T, tn-T1= T, (n-1) × T = T, n is a positive integer. It should be noted that the time delay such as the transmission delay and the propagation delay is ignored.

And under the condition that the vehicle-mounted communication terminal receives the acquisition instruction, the vehicle-mounted communication terminal can extract the enabling information in the configuration instruction through the decapsulation process and generate a request enabling message according to the configuration instruction. And then sending the request enabling message to the electronic control unit to indicate to start the electronic control unit to start the function according to the request message, and executing the step of sending the subscription event group to the electronic control unit after enabling. When the vehicle-mounted communication terminal and the electronic control unit adopt an SOME/IP transmission protocol for communication, the subscription event group can be a Fire & Forget message in the SOME/IP transmission protocol. It should be noted that, unlike the event message, the event message may trigger the electronic control unit to periodically upload the car data, and the Fire & form message is a message with return or no return, and the Fire & form message may be used to notify the electronic control unit to execute the function indicated by the Fire & form message without returning a message. It should be noted that, the reason why the electronic control unit is enabled before the step of sending the subscription event group to the electronic control unit is that the electronic control unit cannot acquire the vehicle data before the function of the electronic control unit is started.

And then determining a corresponding electronic control unit according to the data type, generating a request enabling message according to the enabling information, and generating a subscription event group according to the acquisition duration and the acquisition period. Then sending a request enabling message to the determined electronic control unit to enable the electronic control message to start the function, then sending a subscription event group to the determined electronic control unit to enable the electronic control unit to periodically send automobile data, and sending the received automobile data to the collector according to the address information when the automobile data is received each time.
In summary, when the vehicle-mounted communication terminal receives the acquisition instruction, the electronic control unit may be configured, and through the subscription event group, the electronic control unit periodically generates and uploads the automobile data after receiving the subscription event group. Therefore, the embodiment of the application flexibly selects the automobile data to be collected by configuring the electronic control unit on one hand, and carries out long-time and periodic monitoring on the automobile data by indicating the electronic control unit to periodically upload the automobile data on the other hand, so that the real-time performance of data collection is improved. In summary, the embodiment of the application improves the problems of fixed content and low real-time performance of data acquisition in the prior art.

Next, the data collection method provided in this embodiment will be described with the electronic control unit as an execution subject. Specifically, the method comprises the following steps:
601: and under the condition of receiving the subscription event group, periodically collecting original data according to the subscription event group, and generating an extensible markup language file according to a preset data model and the original data.
After receiving the subscription event group, the electronic control unit periodically collects the original data according to the collection period and the collection duration in the subscription event group. Whenever raw data is collected, the raw data is processed according to a preset data model (i.e. the same data model as that used by the server, which may be a YANG data model) to generate an eXtensible Markup Language (XML). That is, the original data is filled into the format indicated by the data model, so as to obtain the extensible markup language file conforming to the format indicated by the data model, and the extensible markup language file can store the identification of the receiver of the same data model. It should be noted that the server (including the collector, the controller and the analyzer), the vehicle-mounted communication terminal and the electronic control unit can store the data model.
For example, the code representation of XML may be as follows:
wherein the XML represents the vehicle data of the electronic control unit identified as 1, including: the name is air conditioner, the mode is refrigeration, and the wind speed is automatic.
602: and packaging the extensible markup language file to obtain automobile data, and sending the automobile data to the vehicle-mounted communication terminal, so that the vehicle-mounted communication terminal packages the automobile data again after receiving the automobile data, and uploads the packaged automobile data to the collector.
When the extensible markup language file is generated once, the electronic control unit encapsulates the extensible markup language file to obtain automobile data and sends the automobile data to the vehicle-mounted communication terminal, so that the vehicle-mounted communication terminal encapsulates the automobile data again after receiving the automobile data and uploads the encapsulated automobile data to the collector. For example, the electronic control unit encapsulates the xml file according to the SOME/IP transport protocol to obtain the car data, and sends the car data to the on-board communication terminal, so that the on-board communication terminal encapsulates according to the UDP transport protocol.
In summary, the present application provides a data collecting method applied to an electronic control unit, where after receiving a subscription event group, the electronic control unit periodically uploads automobile data according to an indication of the subscription event group.
