Referring to fig. 1, the data acquisition device specifically includes: the system comprises a protocol storage module 110, an information sending module 120, an information receiving module 130, an information screening and obtaining module 140 and an information reorganizing module 150.
The protocol storage module 110 is respectively in communication connection with the information sending module 120, the information receiving module 130, the information screening obtaining module 140, and the information reorganizing module 150, and is configured to store the associated content of a plurality of signals determined according to the standard test requirement, where each piece of associated content of the signals at least includes an ID of a request signal, a content of a field in the request signal, a sending time interval between fields in the same request signal, an ID of a received signal, a position and a value of an identification field in the received signal, a position of a target field in the received signal, an ID of a forwarding signal, a position of data corresponding to the target field in the forwarding signal corresponding to the ID, a sending time interval between different signals, and a processing manner after information is received.
The processing manner after the information is collected includes directly sending the information to the data receiving device 160 and/or sending the information to the information reorganizing module 150 for reorganizing. Further, the reorganized information is sent to the data receiving device 160 and/or to the information sending module 120, so that the reorganized information is sent to the vehicle-mounted network of the vehicle through the information sending module 120, and other external devices can conveniently obtain the reorganized information directly from the vehicle-mounted network of the vehicle.
The protocol storage module 110 is further configured to control the information sending module 120 to roll and send the request signals with different IDs and the contents of the fields in the same request signal to the automobile diagnostic interface 170 in a list circulation manner according to the sending time intervals between the fields in the same request signal and the sending time intervals between different signals stored in the protocol storage module, so as to orderly obtain the required data, avoid the complexity of subsequent data processing operations caused by confusion between different data, and facilitate the improvement of the data obtaining efficiency.
The information transmitting module 120 is communicatively connected to the automobile diagnostic interface 170, and a communication protocol used by the plurality of signals stored in the protocol storage module 110 is adapted to a communication protocol used by the automobile diagnostic interface 170 and an on-board network of the automobile.
The protocol storage module 110 is further configured to control the information collecting module 130 to receive, from the automobile diagnosis interface 170, a signal whose ID is the ID of the received signal based on the request signal of different IDs and the signal fed back by the content of the field in the same request signal according to the stored ID of the received signal; the information collecting module 130 is further in communication with the information filtering and obtaining module 140, and is configured to send a signal received by the information collecting module to the information filtering and obtaining module 140.
After sending the request signal to the automobile diagnosis interface 170, the automobile diagnosis interface 170 feeds back signals of multiple IDs, and in order to obtain the targeted signal, the information collecting module 130 pre-agrees with the ID of the signal to be received, so that the information collecting module 130 only receives the signal with the ID of the received signal, thereby achieving the purpose of first screening and filtering the signal, reducing the difficulty of subsequent processing operation on the signal, and improving the data obtaining efficiency and accuracy.

The location of the identification field and the value of the identification field in the received signal are used to determine the valid signal in the signal received by the information receiving module 130, that is, the data required for the benchmarking test. For example, the location of the identification field in the received signal is the first two bytes, the value of the identification field is 01, and if the value corresponding to the first two bytes of a signal received by the information receiving module 130 is 01, the signal is considered as a valid signal. In summary, the information filtering and obtaining module 140 filters data corresponding to a target field according to the position of the identification field in the received signal and the value of the identification field, and the position of the target field in the received signal, including: the information filtering and obtaining module 140 compares the data of the field corresponding to the position of the identification field in one signal of the received signals with the value of the identification field, and if the data of the field and the value of the identification field are equal, the one signal is determined to be a target signal; and screening out the data at the position of the target field in the target signal to be used as the data corresponding to the target field.

In order to facilitate efficient data acquisition by external devices, including data receiving devices, an arrangement between specific fields of the forward signal may be pre-agreed, for example, a signal that is forwarded as 8 bytes, the first two bytes may be agreed for storing vehicle speed data, and the second two bytes may be agreed for storing engine speed data. And if the position of the data corresponding to the target field in the forwarding signal of the corresponding ID is the first two bytes, storing the data corresponding to the target field at the first two bytes of the forwarding signal of the corresponding ID when the data is recombined. In summary, the information reorganizing module 150 is configured to reorganize data corresponding to a target field according to an ID of the forwarding signal and a position of the data corresponding to the target field in the forwarding signal of the corresponding ID, including: and storing the data corresponding to the target field in a corresponding position in the forwarding signal of the corresponding ID.
Further, the information sending module 120 forwards the recombined signal to the vehicle network of the vehicle through the vehicle diagnosis interface 170 according to a set frequency, so that other external devices can obtain the recombined signal from the vehicle network. The set frequency is determined by the information reorganizing module 150, the information reorganizing module 150 sends a reorganized signal to the information sending module 120, and the information sending module 120 performs an operation of forwarding the reorganized signal to the vehicle network of the vehicle through the vehicle diagnosis interface 170.
Further, when data at a location in a forwarding signal of an ID is updated, the forwarding signal of the ID is retransmitted. In particular, in the whole device, each module does not store data, all the data keep high timeliness, hysteresis is reduced as much as possible, and if the connection is disconnected and the like in the middle, real-time data is directly recorded after reconnection.
The embodiment has the following technical effects: the method can automatically acquire the automobile diagnosis data for the target test, and can realize the purpose of efficiently acquiring the target data according to the test requirement by screening and reorganizing the received automobile diagnosis information and transmitting the information to a device receiving end or directly transmitting the information to the upper part of an automobile network again.
