For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed but may optionally include other steps or elements not listed or inherent to such process, method, article, or apparatus.
At present, the existing method for processing data by diagnosing joints in the process of diagnosing an automobile system is single-channel transceiving, as shown in fig. 1, when a plurality of systems exist, only one system can be scanned at a time, other systems wait for the completion of the first scanning and then sequentially go on, while the automobile is provided with a plurality of systems, when the automobile is scanned in a whole system, the time for processing data by diagnosing joints is very long, so that the diagnosis efficiency is low and the experience of customers is influenced.
In the existing diagnosis process, the data processing mode of the diagnosis joint is single-channel transceiving, when a plurality of systems exist, only one system can be scanned at a time, and when a plurality of systems exist, the data processing time of the diagnosis joint is the number of the systems multiplied by the scanning time of a single system, so that the speed of diagnosis is low, and the working efficiency of diagnosing the automobile system is low.
Based on the above, the embodiment of the application provides a multi-channel-based communication method, a multi-channel-based communication system and electronic equipment, and by the method, the technical problem of low working efficiency in diagnosing an automobile system can be relieved.
Embodiments of the present invention are further described below with reference to the accompanying drawings.
Fig. 1 is a flow chart of a multi-channel communication method according to an embodiment of the present application.

As shown in fig. 2, the method includes:
in step S210, in response to the distance between the connection device and the target vehicle to be diagnosed being smaller than the specified distance, RFID communication connection is established between the RFID chip and the target RFID reader-writer on the target vehicle through RFID identification.
The designated distance is an RFID communication distance threshold. Illustratively, the diagnostic connector, i.e., the connection device, is configured to quickly establish an RFID connection using RFID identification technology when the RFID communication distance is met prior to wired connection with the vehicle.
In step S220, the target RFID reader obtains RFID tag data corresponding to the plurality of systems to be diagnosed from the RFID chip by using RFID communication connection with the RFID chip.
Wherein, different RFID tag data can correspond to different systems to be diagnosed.
When the connecting device is not inserted into the target vehicle, the target RFID reader-writer on the connecting device is close to the target vehicle, and when the target vehicle approaches to a certain distance range, the target vehicle can communicate with the RFID chip through the RFID reader-writer, and a plurality of pieces of automobile system data to be scanned and diagnosed, namely the data of the system to be diagnosed, are acquired.
In practical applications, the vehicle diagnostic device may package communication commands of multiple vehicle systems to be diagnosed (i.e., multiple vehicle systems to be diagnosed), such as bus parameters, communication protocols, and query instructions, where after the connector on the vehicle diagnostic device is successfully connected to the RFID of the target vehicle, the connector sends the communication commands of the multiple vehicle systems to be diagnosed to the target vehicle through RFID tag data.
In step S230, the target vehicle performs system scanning through a plurality of channels based on a plurality of systems to be diagnosed, so as to obtain system scanning result data corresponding to the plurality of systems to be diagnosed.
Wherein, each of the plurality of systems to be diagnosed corresponds to a channel.
In practical application, when the connecting device approaches the target vehicle to a certain distance range, the automobile system to be scanned and diagnosed can be preprocessed through communication between the RFID reader-writer on the connecting device and the RFID chip on the target vehicle.

For example, after the diagnostic connector executes the communication command by using a plurality of channels, the result is returned to the diagnostic connector, so as to achieve the purpose of the concurrent scanning system.

Furthermore, the diagnosis joint can optimize the scanning speed of the automobile system by using a multichannel technology, and can process a plurality of system scanning data at one time through a multichannel mechanism and transmit the data back to the upper computer, so that the diagnosis speed is effectively improved, and the diagnosis work efficiency of the automobile system is further improved.
